That is a human judgment the +script cannot make, and pretending otherwise would be the same error as the prose guard. + +## B4 (High) — #2638 and #2828 were assigned from stale review evidence. ACCEPTED + +Both moved since triage. Live: #2638 head `375e6f8fb8`, ahead 6 / behind 0, +`CHANGES_REQUESTED` (bound to the older `c8556f3703`). #2828 head `019c792607`, ahead 5 / +behind 0, no longer draft. + +Amendment: both leave the reimplementation lane and enter a current-head re-audit lane +(wp9). Discarding an author's branch because of a finding already fixed on a newer head +would be both wasteful and unfair to the contributor. Reimplementation stays available if +the current head still fails review. + +## B5 (High) — rebasing destroys the exact-head-approved premise. ACCEPTED + +`dismiss_stale_reviews_on_push: false` means GitHub will happily keep an approval that no +longer describes the code. The plan leaned on approvals granted to pre-rebase heads. + +Amendment: after any rebase, the approval is re-earned on the new head (B3's check enforces +it mechanically). The reviewer's falsification work is recorded as supporting the plan: it +inspected the failing logs of #2822, #2821, #2796, #2835, #2797, and #2785 and found ONLY +the `release version line` assertion — no unrelated failure. The inheritance thesis stands, +now independently confirmed and additionally proven by #2836's own `test 2/4 = pass`. + +## B6 (High) — verifier claims overstated. ACCEPTED, CAUSE CORRECTED + +The reviewer found `bun x tsc --noEmit` exiting 1 with +`error TS2688: Cannot find type definition file for 'bun-types'`. Verified: the cause was +that this worktree had no `node_modules` at all. After `bun install` (103 packages), +`bun x tsc --noEmit` exits 0. So it is a usable verifier once dependencies exist — the +plan's omission was the bootstrap step, not the command. + +Accepted without reservation: `bun run skill:surface` WRITES its target and is a generator; +the verifier is `bun run skill:surface:check`. Also accepted: `ocx-run` evidence is +meaningless unless the remote workdir is proven to be at the exact head SHA and the child +command actually exercises the change. Both are now required in the evidence format. + +## B7 (High) — missed cross-lane collisions on `src/server/responses/core.ts`. ACCEPTED + +The plan named only the `destination-policy.ts` collision. Live intersections: +`src/server/responses/core.ts` is touched by #2807 (wp4), #2497, #2638, #2793, and #2744. +`package.json` is touched by wp8 and #2744. + +Amendment: wp4 (#2807) is serialized BEFORE every other core-touching member, and each +later core-touching member re-verifies against the accumulated `core.ts` rather than +against the tree it was written on. + +## B8 (Critical) — #2798 called "no security surface". ACCEPTED + +The hygiene gate's restricted list does clear all five wp2/wp3 members +(`restricted=NONE` for #2799, #2798, #2822, #2821, #2785), so there is no gate +misclassification. But `src/lib/destination-policy.ts` decides whether an OAuth bearer may +be sent to an overridden destination, and `MAINTAINERS.md` covers "other security-boundary +changes", not just the mechanical list. Calling it non-security was wrong. + +Amendment: #2798 is security-gated in wp2 and needs a fresh exact-head security review +after rebase. #2812 (wp5), which edits the same file, inherits that classification. + +## Residual disagreement + +None outstanding.

History: user prompt → assistant text + `toolCall` +(`fc_abc123`, `exec_command`, `{"cmd":"echo AAA"}`) → `toolResult` (same id, output `AAA`). + +Decoded roots for `grok-4.6-high`: + +``` +root[0] {"role":"system", ...} +root[1] {"role":"user","content":[{"type":"text","text":"Run echo AAA then echo BBB."}]} +root[2] {"role":"assistant","content":[{"type":"text","text":"I will run echo AAA."}]} +root[3] {"role":"assistant","content":[{"type":"text","text":"[Tool Result]\n[tool_result]\n + call_id: fc_abc123\nname: exec_command\nis_error: false\noutput:\nAAA"}]} +ACTION: userMessageAction +ACTION TEXT: "Continue: the requested tool results are provided in the conversation history above." +``` + +**The assistant tool CALL is absent.** `root[2]` keeps only the assistant's prose; the +`toolCall` content part is dropped. `root[3]` then presents a *result* — complete with a +`call_id` that refers to a call the model cannot see anywhere in its context. + +The omission is deliberate and documented in `src/adapters/cursor/protobuf-request.ts` +(`rootPromptMessages`, external branch): + +``` +// Assistant tool CALLS are intentionally NOT replayed as visible "[Tool Call]" text here. +``` + +The same asymmetry exists in `conversationTurns`: for `externalModel` it replays only +`part.type === "text"` and explicitly skips `toolCall` parts, while the `toolResult` branch +pushes a `[Tool Result]` assistant step. + +### Why an orphaned result produces exactly these symptoms + +From the model's point of view the transcript reads: *I said I would run a command. Then a tool +result appeared for a call with an id I never issued. Now a user message tells me to continue.* +Both observed behaviors are the natural completion of that context: + +1. **Duplicate execution.** The intended call is not in the transcript, so the most probable + continuation is to issue it — which is exactly what a well-behaved agent does when it announced + an action it cannot see itself having taken. +2. **Phantom "was interrupted".** The model must explain a result with no originating call. The + available story is that the earlier attempt was cut off. It then "re-runs it properly". + +The infinite-output case is the same loop without a lucky exit: every continuation re-adds an +orphaned result, so the same reasoning fires again. This is also why the existing repetition +breaker does not save the turn — the repeated entries are *not byte-identical* (each carries a +different `call_id`), so the `pushDeduped` collapse never triggers. + +## 4. Why existing mitigations do not cover it + +| Mechanism | Why it misses this defect | +|-----------|---------------------------| +| `CursorEnvelopeEchoSniffer` | Watches the model's **output** for an echoed envelope.

Conclusion + +The external replay path is internally inconsistent: it drops assistant tool calls but keeps tool +results that reference them by id. The fix is to make the replayed transcript self-consistent by +emitting the call immediately before its result, keyed by call id, without touching the native +composer path (which carries real `mcpToolCall` structures on `turns[]` and must stay untouched — +replaying native structures for external workers is what caused the earlier `invalid_argument` +rejections documented in the same file). + +Implementation phases: `010` (pairing in root replay + conversation turns), `020` (regression +tests, remote verification, delivery). + diff --git a/devlog/_fin/260829_cursor_tool_continuation_pairing/001_audit_round1.md b/devlog/_fin/260829_cursor_tool_continuation_pairing/001_audit_round1.md new file mode 100644 index 0000000000..b65f47c362 --- /dev/null +++ b/devlog/_fin/260829_cursor_tool_continuation_pairing/001_audit_round1.md @@ -0,0 +1,174 @@ +# 001 — Audit round 1 (direct independent audit, blockers folded) + +Auditor: dispatched `explorer` lane (`cursor-plan-auditor`, agent `01a04d5c`) produced no +output across five bounded `wait_agent` cycles (~10 minutes).

The live case it *excludes* is the one that matters: `composer-2.5` +(non-fast) is native (`externalModel === false`) yet `echoToolResultInRoot === true`, so +`rootPromptMessages` DOES write an orphaned `[Tool Result]` into its root prompt while the +planned guard would have skipped emitting the pairing call for it. + +That is not hypothetical. `discovery.ts:200-210` documents `composer-2.5` misbehaving with +exactly the symptom class in `000_rca.md`: it "resumes a tool-result turn with server-side +native tool calls (read/grep/exec) instead of answering, or completes with zero text". The +existing mitigation switched its action shape; it never fixed the orphaned root. + +**Fold:** gate the root emission on `echoToolResultInRoot` alone. The invariant is *wherever a +tool result is echoed into root as text, its call must be there too* — which is exactly the set +`echoToolResultInRoot` describes. The `conversationTurns` change stays keyed on +`externalModel`, because the native branch already emits a real `toolCall` step (F1). + +### F3 — Which surface the model actually reads + +`protobuf-request.ts:186`: "Cursor builds the actual model prompt from +`rootPromptMessagesJson` (`turns[]` is UI/display metadata)". The root change is therefore the +load-bearing fix; the `conversationTurns` change is consistency for the display/structure +surface. Recorded so the test weighting reflects it: the root assertions are the ones that prove +the defect fixed. + +### F4 — `arguments` is an object, not a string (was claim 6) + +`src/types/request.ts:211-215`: + +```ts +export interface OcxToolCall { + type: "toolCall"; + id: string; + name: string; + arguments: Record; +``` + +**Fold:** drop the "string or object" branch from `010` §3.1.

A call entry carries the SAME `messageIndex` as its assistant message, so the +computed `historyMessageStart` can only equal a value the assistant entry would already have +produced — it cannot point past a retained message, and `conversationTurns` slices by message +index, not entry count, so no turn is duplicated. Classing the entry `toolResult` also makes the +`activeStart` walk (`:322`) keep a call attached to its result as one active block, which is +the desired behavior. + +One real consequence: `truncateToolResultBlob` will now also truncate an oversized CALL entry +(it accepts any `role === "toolResult"` entry with `text`). That is acceptable — a call whose +arguments exceed the budget is better truncated than dropped — and is noted rather than changed. + +### F7 — Repetition breaker (was claim 4) + +`pushDeduped` collapses only *consecutive byte-identical* entries. Two different calls differ by +`call_id`, so no collapse. Two identical retried calls (same id, same arguments) would collapse +with a `produced N times in a row` note, which is the intended signal. No conflict. + +### F8 — BLOCKER (Medium): a documented prior rejection of this exact rendering + +`src/adapters/cursor/request-builder.ts:223-235`, `contentPartToText`: + +```ts + case "toolCall": + // Cursor does not accept OpenAI Responses assistant tool-call parts as native history here. + // Rendering them as visible "[tool_call]" text leaks synthetic protocol markers back into + // model output and can halt multi-tool continuations. The paired tool result carries the + // call id/name/output Cursor needs for the next action. + return undefined; +``` + +This is a THIRD site (the `messages` text channel, `CursorRequestMessage`) and it explicitly +rejects rendering tool calls as `[tool_call]` text. Two honest observations: + +1. That channel is not the wire root replay — it feeds `activePromptText` and omission-marker + reconstruction.

Its stated risk — the model echoing synthetic markers back — is REAL and applies to the new + root entries. Note that root already carries `[tool_result]` markers, so the risk is already + accepted for results; adding the paired call is symmetric, not novel. + +**Fold:** convert that residual risk into a covered one.

"an id reused in +covered history yields no invocation line" passes under *both* variants, because there the reused id +is ambiguous within the suffix too. The distinction only shows up when the ambiguity is visible in +full history but not in the suffix, which is what the added case constructs. + +**Three** of the six assertions fail without the threading and pass with it; the other three are +guards that must hold either way, and they document what the widened lookup must *not* break. + +An independent final-gate review corrected this count. The original text said two of five, which was +wrong on both numbers: the sixth test was added after the table was written, and it fails against a +missing threading too, not only against a `size > 0` fallback. Without the threading `knownCalls` is +`undefined`, so the suffix-only index sees one candidate and names `echo SECOND` for a result whose +output is `FIRST` — the same wrong label, reached by a different route. Measured at `1241a8d5c`: +reverting only the call-site threading gives **16 pass / 3 fail**. + +The fix is therefore better covered than the first version of this record claimed. Recorded because a +reader who reverts the threading expecting two failures would not know whether they were looking at a +stale doc or a real drift. + +Two shapes needed care while writing them: + +- An empty `ConversationStateStructure` serializes to **zero bytes**, which the encoder reads as + "no checkpoint" and silently downgrades to full replay. A test seeded that way passes while + exercising the wrong branch. The helper seeds one real root blob instead. +- A turn only opens on a user message, so a suffix of just `[toolResult]` produces **no turns at + all** (measured: `turns=0`).

Both items below are **pre-existing** +and neither is induced by the checkpoint cut. + +**A fourth emission site, line ~1025.** The `conversationTurns` native branch resolves its call from +suffix-local `pendingToolCalls` and, on a miss, falls through to a bare `toolResultToText(message)` +with no invocation line. It never consults `knownCalls`. Measured: full replay and checkpoint produce +byte-identical bare output on the same interleaved input, so the cut does not induce it. + +**The two builders gate on different predicates.** `rootPromptMessages` uses +`cursorNeedsExternalToolContinuation`; `conversationTurns` uses `isCursorExternalWireModel`.

Whether +`composer-2.5` turn steps should also name the invocation is a behaviour question about a native +model's replay, not a checkpoint-indexing bug, so it is not folded in here — it belongs to a unit that +can verify the native path end to end rather than being changed on inference. +- `bun x tsc --noEmit` — exit 0. +- Full suite on `ssh lidge`; no local full-suite run was used as a gate. + +## What the live runs did and did NOT prove + +This has to be stated plainly, because the previous phase of this unit recorded a live claim that +turned out not to hold. + +Three live `codex exec` runs against `cursor/grok-4.6` through a patched probe on port 10199, all +confirmed served by that probe (`cursor:run-request` present in its own diagnostic log): + +| Run | Commands requested | Unique `command_execution` items | `interrupted` | Terminated | +|-----|--------------------|----------------------------------|---------------|-----------| +| 1 (3-step) | 3 | 3 | 0 | `ALLDONE`, exit 0 | +| 2 (4-step) | 4 | 3 | 0 | `turn.completed`, no `ALLDONE` | +| 3 (4-step, same prompt as 2) | 4 | 4 | 0 | `ALLDONE`, exit 0 | + +**Every one of the 13 requests across those runs used `continuationMode: "full-replay"`.** The +checkpoint branch this PR changes was never entered, so these runs do NOT verify the fix.

Replacing it with a whole-history index removes that bound. +Measured with a result at index 1 and its id's call at index 3 (`echo LATER`): + +| tree | output | +|------|--------| +| base | `TEXT invoked=false` | +| patched | `TEXT invoked=true — invoked: exec_command with {"cmd":"echo LATER"}` | + +The ambiguity guard does not catch this, because one call for an id is not ambiguous. I re-derived it +independently: `resultIndex=1`, `callIndex=3`, `callIndex > resultIndex` is true. This is precisely the +failure the index's own doc comment calls unacceptable — "an early result could be labelled with a +later command… a wrong invocation is worse than none". The root path escapes it only because it skips +results at or after `activeUserIndex`; the turn path has no such bound. + +**B2 — the added line can make a request fail to encode.** The turn path stores one blob per step with +no truncation guard. The root path has `truncateToolResultBlob`; `toolCallStep` degrades by dropping +images; this `else` branch has neither, and `storeCursorBlob` throws `CursorBlobAdmissionError` +unconditionally on rejection. With the entry ceiling lowered to reach the boundary cheaply, a +large-but-legal argument plus a result that fits in base threw `entry_too_large` in the patched tree. +The plan's cost section discussed only the 2 KB argument cap, never the step-blob total. + +**B3 — the "no-index guard" test row was false, and it was the row that would have caught B1.** +`nativeCalls` was unconditional, so no model stays un-indexed. Measured `invoked=false → true` for +`composer-2.5-fast`, `auto`, and `auto-intelligence`. A test asserting "unchanged" would have failed +immediately and been quietly rewritten to match observed output — the exact mechanism that produced +three partial fixes in this unit already. + +Plus: the affected set is wider than this plan listed. `isCursorNativeWireModel` returns true for +`auto` and `default` as well as `composer-*`, so `auto` and `auto-intelligence` reach the branch too. + +## Design v3 + +Three constraints, one per BLOCKER. + +**Positional bound (B1).** The fallback accepts a call only when it appears *before* the result in +history. That needs an index carrying position, so `toolCallsByCallId` gains a variant that records the +message index of each first binding, and the fallback compares against the result's own index. A call +at a later index yields no invocation line — the honest degradation the existing code already prefers. + +**The bound must compare within ONE coordinate system, and this is the trap.** `040` threads a +**full-history** index into a **sliced** replay: `buildPreparedCursorRunRequest` builds +`toolCallsByCallId(request.rawMessages)` and hands it to `conversationTurns`, which then iterates +`rawMessages.slice(suffixStart)` using slice-local positions. Comparing a full-history `callIndex` +against a slice-local `resultIndex` compares two different origins. Worked example with +`suffixStart = 4`, the call at full index 1 and the result at full index 4: + +| comparison | result | +|------------|--------| +| full vs full (correct) | `1 < 4` → accept | +| full vs slice-local (naive) | `1 < 0` → **reject** | + +A naive bound therefore drops the invocation line for a legitimately earlier call — silently +re-creating, on the checkpoint path, the exact orphan #2910 was merged to fix. So the fallback must +either receive the suffix offset and compare `callIndex < suffixStart + localIndex`, or the index must +be built over the same message array the loop walks. Whichever is chosen, a test must pin the +checkpoint case specifically, because a unit test on full replay alone cannot see this. + +**Byte budget (B2).** The rendered step is measured against `cursorBlobMaxEntryBytes()` before it is +stored. If naming the invocation would not fit, the envelope is emitted **without** the invocation +line rather than throwing: the result output is the payload, the invocation line is a convenience, and +that ordering is already established by the root path's `PROBE a huge argument must not evict the +result output` test. + +**Honest scope (B3).** The change affects every model that reaches this branch — `composer-2.5`, +`composer-2.5-fast`, `auto`, `auto-intelligence` — and the tests must assert that, not the opposite. +No test claims a model is unchanged when it is not. + +What stays untouched: the `if (priorCall)` paired path. The auditor confirmed it is byte-identical +across all five models in the patched tree, and it produces a real `mcpToolCall` protobuf step +carrying both halves, which is strictly better than any text envelope. + +### The 363-B question, answered rather than inherited + +The previous draft asserted safety by inheritance. The specific guard forbids a `[Tool Call]` marker, +and `toolInvocationLine` emits none — confirmed, no `[Tool Call]` string appears in any patched turn +step. But the auditor named a shape that does not exist on the external path: the text envelope now +sits directly beside a genuine `mcpToolCall` step describing the same call, so the same invocation is +described twice in one turn. Given that `040` already records a live `composer-2.5` run fabricating a +`[Tool Result]` envelope as chat, that duplication is not obviously harmless. + +This is why the phase does **not** widen the gate and does not proceed on inference. The narrow +question — a result whose call is genuinely absent from the current turn gets its invocation named, +bounded by position and by bytes — is decidable from the wire. Whether a native model should see the +same call described twice is a live-behaviour question, and it is deferred with that reason stated. + +## The predicate question, deliberately not answered here + +`turnCalls` is gated on `isCursorExternalWireModel`, while the root builder gates on the wider +`cursorNeedsExternalToolContinuation`. They disagree for `composer-2.5` (true vs **false**), so this +change alone will not name the invocation for that model's turn steps. + +Widening the turn gate to match would change what a *native* model receives on its resume path, and +this unit has already shipped three partial fixes by reasoning about the Cursor wire instead of +measuring it. The gate stays as it is; the asymmetry stays recorded in `040`. What this phase fixes is +the case where the index already exists and was simply not consulted. + +## Tests + +In `tests/cursor-tool-result-invocation.test.ts`, driven red before the fix: + +Two rows of the previous table were factually wrong and audit r2 rejected them: one named an +"external" model when every model reaching this branch is native by `isCursorExternalWireModel`, and +one asserted native turn steps were "unchanged" when the patch changes them for four models. A test +that asserts the opposite of what the code does gets quietly rewritten to match observed output, which +is how this unit shipped three partial fixes. + +| Test | Without the fix | +|------|-----------------| +| a native result separated from its call by a user message names its invocation in the turn step | **red** | +| a result whose id's call appears LATER in history gets no invocation line | **red** — B1 bound | +| naming the invocation is dropped, not thrown, when the step would exceed the entry ceiling | **red** — B2 budget | +| a call and result inside one turn still pair into an mcpToolCall step, not text | green — paired-path guard | +| every model reaching the branch is named explicitly (`composer-2.5`, `composer-2.5-fast`, `auto`, `auto-intelligence`) | green — scope is asserted, not assumed | +| `grok-4.6-high` is unaffected, because the external branch handles it before this code | green — disjointness guard | +| on the CHECKPOINT path, a call before `suffixStart` is still accepted by the positional bound | **red** — coordinate-system guard | + +The second and third rows are the ones that did not exist before the audit, and they are the two that +encode its BLOCKERs as executable checks rather than prose. + +## Verification + +- Focused `bun test` on the cursor files. +- `bun x tsc --noEmit`. +- Full suite on `ssh lidge`; no local full-suite run as a gate. diff --git a/devlog/_fin/260829_cursor_tool_continuation_pairing/060_phase7_positional_bound.md b/devlog/_fin/260829_cursor_tool_continuation_pairing/060_phase7_positional_bound.md new file mode 100644 index 0000000000..a05efb763a --- /dev/null +++ b/devlog/_fin/260829_cursor_tool_continuation_pairing/060_phase7_positional_bound.md @@ -0,0 +1,278 @@ +# 060 — Phase 7: bound the invocation lookup by position + +Depends on: `11d33597f` (#2910), `cfb70c972` (#2913), `6906049c6` (#2919) on `origin/dev`. +Supersedes the implementation intent of `050`; that unit's own defect is now the smaller half of this +one. + +## Why this replaces 050 + +`050` set out to name the invocation on a native turn-branch fallback.

The index implements the *ambiguity* half of that comment and +not the *ordering* half. + +So the priority inverts. A missing invocation line on a native turn step is a cosmetic gap; a **wrong** +invocation line on the shipped external root path is the defect this unit exists to prevent, and I +introduced it in #2900. + +## Root cause + +`toolCallsByCallId` carries no position.

The comment's parenthetical — "results follow their call, so the first binding is the +one an earlier result belongs to" — is an assumption about history order, not something the code +checks. + +`050`'s draft claimed the root path escaped this via `activeUserIndex`. That is false, and audit r3 +disproved it: `activeUserIndex` is `-1` whenever the last raw message is a `toolResult`, and otherwise +it bounds the loop end, never the call index. I re-measured it above on the shipped tree. + +## Reachability, stated honestly + +This needs a history where a result's id is first claimed by a *later* call. It is not the common +shape: Codex normally replays a full thread in which the call precedes its result. + +My first draft framed the precondition as id reuse. Audit r4 corrected that — **the actual +precondition is only "a result precedes its call in serialized order"**, and it is reachable without +any id reuse at all: a result serialized before the assistant message declaring its call was measured +being labelled from that later message, with two distinct ids. Routes: + +- a result emitted before its own call in the serialized order — no reuse required; +- an id reused by a retry after the original call has left the replayed window. + +It also does not need a contrived trailing shape. On the ordinary trailing-`toolResult` continuation — +the single most common shape this proxy sees — `activeUserIndex` is `-1` and the loop walks the entire +history, so nothing bounds the lookup at all. + +I have **not** produced this from a live `codex exec` run, and I am not claiming a live repro. What is +demonstrated is that the encoder produces a confidently wrong label when given the shape, on the path +that ships today. Given that a mislabel is undetectable downstream by design, that is worth closing on +its own terms rather than waiting for a user to hit it. + +## The change + +Give the index position, and require the call to precede the result. + +`toolCallsByCallId` gains a companion that records the message index of each first binding. Both +emission sites already know the result's index — the root loop has `i` (it already passes +`messageIndex: i` into `pushDeduped`), and the turn loop can carry it. A call at an index **not less +than** the result's index yields no invocation line: the same honest degradation the ambiguity path +already takes. + +### The coordinate-system trap + +Both audits converged on this and it is the reason a naive bound is worse than none. `040` threads a +**full-history** index into a **sliced** replay: the checkpoint path builds +`toolCallsByCallId(request.rawMessages)` and hands it to builders that iterate +`rawMessages.slice(suffixStart)`. A full-history call index compared against a slice-local result +index compares two different origins: + +| `suffixStart = 4`, call at full index 1, result at full index 4 | comparison | outcome | +|---|---|---| +| correct | `1 < 4` | accept | +| naive (full vs slice-local) | `1 < 0` | **reject** | + +Audit r3 measured both directions of this on a patched tree: it rejects valid pairings *and* can +accept for the wrong reason. Rejecting silently re-creates, on the checkpoint path, the exact orphan +#2910 was merged to fix. + +The bound therefore compares in one coordinate system. Two options looked available: + +1. build the index over the **same array the loop walks**; +2. keep the **full-history** index and have the loop convert its local index to full space before + comparing. + +**Option 1 is self-contradictory and this plan initially chose it.** The checkpoint site threads a +full-history index *precisely because the call can sit outside the slice* — that is what #2910 fixed. +Rebuilding the index over the slice removes that call from the index altogether, so the invocation is +lost for exactly the shape phase 5 closed. Worked through with `suffixStart = 2`, the call at full +index 1 and the result at full index 3: + +| option | call in index? | comparison | outcome | +|--------|----------------|------------|---------| +| 1 — rebuild over slice | **no** | n/a | invocation LOST, re-breaks #2910 | +| 2 — full index + offset | yes | `1 < 2 + 1 = 3` | named, and ordering enforced | + +So the design is **option 2**: the index stays full-history, and each emission site converts the +position it walks into full-history space before comparing. The root path already has the full-history +`i` when it is not slicing; the checkpoint path must add its `suffixStart`, which means that offset has +to be passed to the builders alongside `knownCalls` rather than inferred. + +That is one more parameter than option 1 would have needed, and it is the price of not re-breaking the +previous phase. Recording the wrong first choice because "no offset to thread" is exactly the kind of +simplicity argument that produced the last three partial fixes. + +### The three origins ADD — write the expression, not the parts + +There are three offsets in play, and the comparison position is their **sum**: + +```text +resultFullIndex = knownCallsOffset + start + w + + knownCallsOffset : checkpointSuffixStart, or 0 on full replay + start : historyMessageStart in conversationTurns, or 0 + w : the loop's own position within the array it walks +``` + +Audit r5 implemented this plan and then mutation-tested the two readings the earlier prose permitted. +Both typecheck cleanly and passed all 274 cursor tests **plus the five rows the table below had at the +time**.

Correct +arithmetic names the call; both survivors emit no invocation line — re-creating on the checkpoint path +the exact orphan #2910 fixed, which is the failure this document spends its longest section warning +about. + +So the expression is normative. An implementer who derives only one term ships something that looks +green from every angle this plan would otherwise check. + +**Storage mechanism, so review does not relitigate it:** `toolCallsByCallId` returns a bare `Map`, so +positions go in a side table keyed by the returned map — a `WeakMap>` — rather +than changing the return type and every caller. There are four `toolCallsByCallId(` invocations +(`rg -c` on the file) across two builders and the checkpoint site. Audit r6 built the side table exactly +as specified and confirmed the return type and all existing call sites stay unchanged, with positions +recorded on first binding and deleted alongside the ambiguity drop. + +**Loop rewrite caution:** converting `conversationTurns`' `for…of` to an indexed loop should keep an +`if (!message) continue;` guard, matching the existing root loop. Audit r6 corrected my stated reason: +`noUncheckedIndexedAccess` is **not** enabled in this repo, so `walked[w]` types as `OcxMessage` and no +narrowing is lost — removing the guard still typechecks. Confirmed: `grep -c noUncheckedIndexedAccess +tsconfig.json` returns 0. So the guard is a runtime-consistency choice, not a strictness requirement, +and an implementer who tests the original justification would find it did not hold. + +## Tests + +**Exactly one row is red without the fix.** Saying "every row must fail first" would be the same +overclaim `040` was audited for twice: the accept-side rows exist to stop the bound from becoming a +blanket refusal, and a guard that is green before *and* after is doing its job.

The +plain "an ambiguous id yields no line" row I originally listed does **not** catch suffix-narrowing — +measured green under `same-array` — because the ambiguity is visible in the slice too. The guard has to +construct ambiguity that full history sees and the suffix does not. That test already exists in the +tree as `an ambiguous id resolved from full history is not re-resolved from the suffix`, added in +#2919, so this phase must keep it green rather than write a new one. + +Rows 3 and 4 are split because audit r4 showed the single row as worded was satisfiable by the root +path alone, which would let a turn-path regression through. + +Row 6 is the one audit r5 proved was missing, and it must assert against the **turn** path. Audit r6 +built it both ways on identical history and only the turn form discriminates: + +| row 6 asserts against | correct | `knownCallsOffset + w` | ternary | `start + w` | +|---|---|---|---|---| +| turn path | pass | **fail** | **fail** | **fail** | +| root path | pass | pass | pass | fail | + +The reason is structural, not fixture luck. `historyMessageStart` is an *output* of +`rootPromptMessages`, assigned only after its loop finishes, while that loop walks full-history `i` from +zero — so the root path's expression reduces to `knownCallsOffset + 0 + i` and `knownCallsOffset + w` is +*identical* to the correct one there. No root-path test can ever separate them. Only +`conversationTurns` carries `start = historyMessageStart` into its slice. + +This is the same defect rows 3 and 4 were split to avoid, in the one row that must not have it: a +table that cannot distinguish a correct derivation from a plausible wrong one is the shape of every +earlier failure in this unit. Row 6 is also the only row whose preconditions must be checked rather +than assumed — r6 instrumented it and confirmed `offset=1 start=1 w=2`, both offsets genuinely +non-zero, so the row exercises the composition instead of being incidentally satisfied. + +### Measured across implementations + +Audit r4 implemented every coordinate option behind one knob and ran identical tests: + +Test counts below differ by **file scope**, not because the suite grew — r4 measured the three files +this unit touches (124 tests: `cursor-tool-result-invocation` 19, `cursor-tool-continuation` 12, +`cursor-blob` 93), r5 and r6 widened to seven and nine cursor files respectively.

The loop-local position is therefore `start + w`, not `w`. Audit r4 confirmed this third +origin produces no mislabel on its own, so it is an implementation trap rather than a live defect, but +an implementer who reads only the `suffixStart` discussion above will walk straight into it. + +## Scope + +The bound lives in the shared lookup, so it covers every consumer at once — the external root path +(where the mislabel is live), the external turn path, and the checkpoint variants of both. + +The native turn-branch fallback from `050` is **not** included. Audit r3 showed the affected id set is +48 wire ids rather than the four `050` listed, that the paired `mcpToolCall` step already describes the +same call so the envelope is not as orphaned as `050` claimed, and that a raw-vs-decoded id keying +asymmetry between `pendingToolCalls` and the index is unaccounted for. That is a separate phase with +its own measurements, not a rider on a correctness fix. + +## Verification + +### Implementation notes: row 6 took five fixtures to make discriminate + +The plan predicted row 6 would catch a dropped `start` term.

(An earlier draft cited 9..19 against a pinned 5 and a +proxy port that no artifact contains; the property is real, those specific figures were not, and they are +corrected here rather than restated.) + +That explains both halves of the report. The model cannot see the output of the command it just ran two +turns ago ("툴 출력을 못받고"), so it re-runs it; and because every turn presents the same collapsed shape, +it never accumulates enough state to finish ("무한 출력"). + +### Causation, not correlation + +Gating the loop off behind a scratch environment variable, changing nothing else, turns the roots +column from 2, 2, 2, 2 into 3, 5, 7, 9. The scratch mutation was reverted; `git diff` is empty. + +## Why the guard cannot simply be deleted + +It is load-bearing on the full-replay path. `tests/cursor-blob.test.ts` covers the case it was written +for: byte pressure consumes the budget with one large active result, the user turn that asked for it is +pruned, and `conversationTurns()` then discards the result too for lack of a current turn — the wire +request degenerates to system roots plus a bare result marker. #1527. + +The fix must keep that behaviour for full replay and stop applying it to a suffix whose initiating turn +is covered by the checkpoint. + +## Change + +`src/adapters/cursor/protobuf-request.ts`, `rootPromptMessages`: + +1. The function already receives `knownCallsOffset` (added by #2936), which is `suffixStart` on the + checkpoint path and `0` on full replay. A non-zero offset is exactly the "my history starts + mid-conversation" signal the guard is missing. Introduce a named boolean from it — + `suffixContinuesCoveredTurn` — rather than testing the arithmetic inline, because the two meanings + (positional re-basing vs. provenance) must not silently merge again. +2. Skip the orphan-strip loop when that flag is set. A covered-turn suffix has no orphan to strip: its + initiating turn exists, upstream, inside the checkpoint. +3. Leave the `#1527` initiator-recovery block below it unchanged. Its own comment already argues it + needs no mode distinction, and `activeStart > 0` confines it to this call's own slice — so it stays + correct for both paths and is not part of this defect. + +Not in scope: the `suffixStart === 0` edge, where a checkpoint reports zero covered messages and the +suffix is the full history. The flag is false there, which is the correct answer — that request *is* a +full replay in every respect that matters to the guard. + +## Verification + +- Red first: the growth table above becomes a test that asserts roots grow with pairs. It must fail on + `d882caed5` and pass after. +- The `#1527` full-replay assertions in `tests/cursor-blob.test.ts` must stay green untouched; they are + the guard's reason to exist and the only proof this change is narrow. +- `a checkpoint suffix may legitimately begin with a tool result` must stay green — it is the existing + expectation that most nearly overlaps this change. +- Live re-measurement of the exact repro above on an isolated proxy: three commands, one run each, + zero interrupt narrations, terminal `ALLDONE`. +- `bun x tsc --noEmit` and `bun run privacy:scan`; full suite on `ssh lidge`, never locally. + +## Audit r8 reopened the change: one mechanism was not enough + +The first implementation fixed only the orphan-strip loop. An independent audit measured two further +paths to the same user-visible symptom, both confirmed here before anything was changed. + +### The orphan fix is inert under byte pressure + +Eight pairs of 64 KiB results still produced 2 roots, with and without the orphan fix. The `keptPrior` +loop above the guard admits **complete turns**, and a turn starts at a `user` root — which a checkpoint +suffix does not have, by definition. `turnStart` walks to 0, the whole prior block becomes one +all-or-nothing pseudo-turn, and the first budget overrun drops every entry. The orphan guard then has +nothing left to strip, so it never runs and the fix cannot help. + +The remedy is to admit entries individually when the suffix continues a covered turn: without a turn +boundary to respect there is nothing for turn-granularity to protect, and keeping the most recent +history that fits beats keeping none. Measured 2 → 15 roots on that fixture. + +This matters more than a partial loss would, because root replay is the **only** channel carrying suffix +history. `conversationTurns` walks from `historyMessageStart` and never meets a `user` message in a +suffix, so `current` is never created and every entry hits `if (!current) continue` — the suffix +contributes 0 turns both before and after this change. Verified directly rather than assumed. + +### Restored growth collided with the cumulative envelope + +Suffix pruning measured only its own slice, so it produced suffixes that were individually legal and +cumulatively fatal. Once replay actually grew, the downstream envelope guard began throwing +`CursorRootEnvelopeLimitError` — a non-retryable 400 — on conversations that previously degraded +silently: 50 pairs behind 100 checkpoint roots, 10 behind 180, 4 behind 190. Growth was also +non-monotonic, with 95 pairs giving 191 roots and 96 collapsing back to 2. + +Two things were wrong and both are fixed. Pruning now subtracts the checkpoint's own roots and bytes, so +the suffix is measured against the room that actually remains. And when a checkpoint leaves no room at +all, the checkpoint is **abandoned** for a full replay under a new `envelope_exhausted` invalidation +reason rather than pruned to fit. Pruning to fit would emit the covered prefix and silently drop every +uncovered message — this unit's own defect, reintroduced at the top of the range — and throwing would +hand the caller a 400 it cannot retry. A full replay rebuilds a self-contained prompt and prunes it +coherently. After the change all three fixtures stay at 191 roots with no throw and no cliff. + +### The abandon decision reads pruning's result, not a byte threshold + +Two threshold attempts both left a live gap, which is why the predicate ended up where it is. Comparing +carried bytes against the raw limit left a few-hundred-byte band below it where the checkpoint was kept, +the suffix budget collapsed, and the newest tool result vanished — silently, where the old code at least +threw. Adding `systemBytes` moved the band instead of closing it, and the surviving positions were the +instructive ones: pruning kept the assistant narration and dropped the result, then kept the result +truncated so hard that only the truncation marker remained. Both leave the model looking at a call with no +answer, which is worse than keeping nothing. + +So the condition is not predictive. Pruning runs first, and the checkpoint is abandoned when the message +the turn continues from did not survive it. Two earlier attempts at that predicate are worth recording +because each failed differently. Matching the result's own output text against the serialized root broke +on JSON escaping the moment real output contained a newline, which made every live continuation abandon +its checkpoint — correct output, checkpointing silently dead. Checking the surviving roots' roles could not +distinguish the result from the narration beside it. The predicate is now positional: `rootPromptMessages` +returns the source message index of every root that survived, plus the indexes whose output was elided +entirely by truncation, and the caller asks whether the last replayed message is in the first set and out +of the second. + +That second set exists because "the result root survived" is not the same as "the result survived". +Truncation has two ways to leave a root that answers nothing: reduce it to the marker alone, or cut +mid-envelope before the `output:` line. Both were live in the band, and both now set `outputElided` at the +single place that produces them, so no threshold has to guess. + +Swept across 15 positions from 100 KiB below the byte limit to 100 bytes above it, the newest result is +present at every one; before, five positions dropped it. Live turns still resume from their checkpoint +(`mode=checkpoint`, no invalidation reason) — the predicate costs nothing on ordinary conversations. + +Scoped out explicitly rather than silently: the abandon branch sits inside the `suffixStart`-valid block, +so a plain resume turn with an oversized checkpoint still throws as it did before this unit. That path has +no suffix to lose and no measurement here, so widening it belongs to its own phase. + +Two pre-existing tests asserted the throw. They now assert the bound instead: the assembled request stays +inside the envelope and the uncovered history is still present. + +An earlier draft claimed those two rewrites were mutation-checked against the `carriedRoots` subtraction. +The re-audit measured otherwise and it was wrong: both exit through the abandon branch — the count case +uses unmeasurable checkpoint roots, the byte case a checkpoint large enough to trip abandonment — so +neither touched the subtraction. Deleting it reintroduced all three throws with the suite still 97/0 +green. The subtraction now has its own case built to reach it: measurable checkpoint roots, a count three +below the limit so abandonment does not fire, and a suffix that only fits if pruning knows what the +checkpoint spends. Removing the subtraction now reddens three tests. + +## Verification (as performed) + +- Focused suite: `bun test tests/cursor-blob.test.ts tests/cursor-tool-result-invocation.test.ts + tests/cursor-tool-continuation.test.ts` — 138 pass / 0 fail at the head of this unit (133 when this line + was first written, before the later rounds added assertions). +- Every assertion driven red against the implementation it exists to catch, each mutation applied alone: + restoring the unconditional orphan guard reddens the two suffix-growth rows; restoring turn-granular + admission reddens the byte-pressure row; removing the `carriedRoots` subtraction reddens three rows; + neutering the result-survival predicate reddens the byte-band row; skipping the orphan guard + unconditionally reddens the full-replay orphan row. +- Live re-measurement on an isolated proxy built from the final tree, counted after the run exited + (`/tmp/ocxv2.ojEUBe/v2.jsonl`): 3 commands, one execution each, 0 interrupt mentions, terminal + `ALLDONE`. The run-request diagnostics from that same proxy's debug buffer report `rawMessages`/`rootBlobs` + of 3/4, 5/6, 7/8, 9/10 across the four turns, with the last three in `checkpoint` mode and no + invalidation reason — roots tracking history instead of pinned to a constant, and checkpointing intact. + An earlier draft cited a series read from a snapshot log copied out of the operator's home, which could + not be traced to the run it described. +- The operator's own proxy (port 10100, pid 62773, 2.35.0) was never touched; every probe ran against a + scratch `OPENCODEX_HOME` on a scratch port. + +## Audit round 3: the predicate had to learn which path it applies to + +The positional predicate was correct for the path it was written against and wrong for two others. Both +were measured before being changed. + +### Native models were losing their checkpoint on every continuation + +`suffixKeptItsResult` asked whether the replayed result root survived pruning. A native resume model has +no such root: its result travels in server-side turn state, so `echoToolResultInRoot` is false and +`rootPromptMessages` skips it. The question answered "no" unconditionally, which meant the checkpoint was +discarded on **every** native tool continuation — including `cursor/auto`, the default id — regardless of +size or byte pressure. + +That is not a cosmetic loss. `pendingToolCalls`, `readPaths` and `previousWorkspaceUris` exist only inside +the checkpoint, and a full replay does not rebuild them, so this unit's own defect had been relocated to +the native path. Measured through the real builder: `readPaths` went 2 → 0 for `auto`, +`composer-2.5-fast` and `composer-3`, while `composer-2.5` and `grok-4.6` were unaffected — exactly the +split `cursorNeedsExternalToolContinuation` draws. The predicate is now gated on it. + +Worth stating plainly: this was introduced by the fix for the previous round's finding, not by the original +defect. Three rounds of audit each found one, which is the argument for the rounds rather than against +them. + +### Parallel results were protected one at a time + +The check read the last replayed index only. Parallel tool calls arrive as a run of results, and under byte +pressure the older ones were the ones being emptied — a prompt with three calls and one answer, which the +code's own comment calls worse than keeping nothing. `historyOutputElided` already recorded them; nothing +read them. The whole trailing run of results is checked now. Swept 628 (carried-bytes, payload-size) +positions: 10 partial-answer positions before, 0 after. + +### The invalidation reason still reaches nothing, and that is now a recorded decision + +`envelope_exhausted` is assigned to a local, so it lands in the debug diagnostic and stops there. +`src/adapters/cursor.ts` drops a dead checkpoint by reading `request.checkpointInvalidationReason`, so an +exhausted checkpoint is re-decoded and re-abandoned every turn until its TTL. + +Round 3 asked for it to be propagated and the obvious fix — writing the field back onto the argument, which +is what `request-builder.ts` does — was implemented and then measured inert. `live-transport.ts` prepares a +**spread copy** of the request, so the write lands on the copy: the outer object the adapter reads stayed +`undefined`. A test asserting on the argument would have passed while proving nothing about the real path, +which is the same vacuous-coverage trap round 2 caught. + +Reaching the store means threading the reason back through `PreparedCursorRunRequest`, a signature change +on the shared prepare path. That belongs to its own phase. The cost of leaving it is bounded and worth +stating: wasted work each turn, not wrong output — the request assembled is correct either way. + +### Verification of this round + +- `bun test` across `cursor-blob`, `cursor-tool-result-invocation`, `cursor-tool-continuation` and + `cursor-request-builder`: 188 pass / 0 fail, and 102 / 0 in `cursor-blob` alone. An earlier draft said 187, + which matched no commit in the stack — recounted after audit round 4 flagged it. +- Each new assertion driven red against the implementation it catches: removing the native gate reddens the + native-checkpoint row; reading only the last index reddens the parallel row. The parallel fixture's + 375-byte offset was derived from the sweep rather than guessed — it is the one position where a + last-index-only check leaves exactly one answer standing. +- Sweeps re-run clean after the change: 15/15 band positions deliver the newest result, 222 edge positions + (multi-byte UTF-8, empty, whitespace-only, error, self-referential `output:` payload) with no loss, 628 + parallel positions with no partial answers and no throws. + +## Audit round 4: the gate covered one disjunct out of three + +The abandon condition is a three-way disjunction, and round 3 gated only the last term. The middle one — +"the suffix produced no history roots at all" — is about the same thing, a replayed root going missing, so +it was equally meaningless for a model whose results never become roots. + +It fired whenever a native assistant turn was a **bare tool call with no narration**: no text root, no +result root, zero history roots, condition true, checkpoint discarded. Measured on the silent shape, +`readPaths` went 2 → 0 for `auto`, `composer-1`, `composer-2.5-fast` and `composer-3` while +`composer-2.5` and `grok-4.6` were unaffected — the same split, the same loss, one disjunct over. Both +survival terms are gated now; the count-full term stays ungated because it is a real envelope fact +independent of who echoes results. + +### Why four rounds each found something + +Every fix in this unit was correct for the path it was written against and silent about a sibling path in +the same condition. The fixture that let round 4's blocker through was round 3's own test: it asserted the +native path with narration, so the narration-free shape of the same path stayed invisible. The test is now +a cross product — four model ids by four assistant shapes (narrated, silent, empty text, whitespace text) — +because that is the axis the bugs kept hiding along, not because sixteen cases are inherently better than +four. + +Two counts in this document were also wrong and are corrected: the four-suite total is 188, not 187, and +the three-suite figure is 138 at head rather than the 133 true when it was written. + +## Audit round 5: the count budget was computed and never applied to the trailing run + +`historyLimit` subtracts `carriedRoots.count`, and every prior round reasoned about that subtraction as if +it bounded the assembled payload. It did not. It was read by the prior-history `while` loop alone. The +trailing tool-result block was assembled before that loop under **byte** pressure only, and +`historyEntries` was then built as `[...keptPrior, ...active]` with no count check anywhere. When +`keptPrior` is empty — the ordinary checkpoint-continuation shape — `historyEntries.length` equals +`active.length`, bounded by nothing at all. + +`truncateToolResultBlob` cannot save it: shrinking a result frees bytes, never a root slot. + +The abandon condition was supposed to catch the overflow, and it tested +`carriedRoots.count + suffixSystemCount` — carried plus system, asking whether there is room for **one** +more root. A parallel tool-call batch needs `active.length` of them. With 190 carried roots and a +3-result batch the test computes `190 + 1 >= 192` → false, keeps the checkpoint, appends 3 to 190, and +throws `CursorRootEnvelopeLimitError`: status 400, `retryable: false`, and `src/adapters/cursor.ts` fails +closed on the invalid-argument retry path when the last raw message is a tool result, which is exactly +this shape. + +Measured at `bde5b19dd`, before the fix: + +``` +carried=190 parallel=2 -> OK roots=192 +carried=190 parallel=3 -> THROW 193 roots +carried=189 parallel=4 -> THROW 193 roots +carried=188 parallel=8 -> THROW 196 roots +carried=170 parallel=25 -> THROW 195 roots +``` + +Reachable by ordinary growth, not a crafted fixture. Feeding each turn's assembled state back as the next +checkpoint — what `commitCursorCheckpoint` does — a plain conversation of 3-parallel-call turns died at +turn 48, and 5 calls per turn at turn 32. Both survive 200 turns after the fix, as do 1, 2 and 8 calls +per turn. + +The fix bounds `active` by count where it is assembled, rather than adding a fourth disjunct that has to +predict the suffix width. Oldest results drop first, matching the direction byte pressure already prunes, +and at least one always survives; the existing abandon check then reads `historyMessageIndexes`, sees the +dropped result, and falls back to a coherent full replay. That is why the grid shows the newest result +delivered at all 78 positions rather than merely "no throw". + +### Why the existing 188 could not see it + +The three pressure fixtures this document already claims — 50 pairs behind 100 roots, 10 behind 180, 4 +behind 190 — are all **sequential** pairs, and a sequential suffix has a trailing run of exactly 1, the +single width at which `+ 1` predicts the suffix correctly. The 628-position parallel sweep applied +**byte** pressure, where the abandon branch fires before the count cliff is reachable. Both axes existed +in the suite; neither case crossed them. All 188 tests passed identically with and without the production +fix, which is the sharpest available proof that no assertion covered this path. + +`tests/cursor-blob.test.ts` now crosses them: three `test.each` rows (carried 190 × 3 results, 188 × 8, +170 × 25) assert both halves — inside `CURSOR_EXTERNAL_ROOT_BLOB_LIMIT` **and** the newest output still +present, because staying inside the envelope by sending nothing useful is the other half of this defect. +Disabling the new bound reddens exactly those three and nothing else. Four-suite total is 191 pass / 0 +fail, `cursor-blob` alone 105. + +The pattern named after round 4 held for a fifth time, one level up: rounds 2 through 4 all reasoned about +the count budget as a settled fact and argued about the disjuncts consuming it, while the budget itself was +never applied to the wider of the two things it was supposed to bound. + +## Audit round 6: the r5 fix dropped in root space, and the check that guards it read raw space + +The count bound from round 5 acts on `active`, a list of ROOT entries. The abandon check derived its +trailing run by scanning `suffixMessages`, which is RAW messages. The two spaces are not the same, and they +diverge on the most ordinary assistant shape there is: a bare tool call with no narration emits no root at +all, so two sequentially-executed results sit ADJACENT as roots while raw space still separates them with an +assistant message. + +Consequence: both results entered the root-space trailing run, the count bound dropped the older one, and +the raw-space scan — seeing a run of length one, the newest result, which survived — reported "kept". The +checkpoint was retained and the request went out with a tool call answered by nothing. Measured at 190 +carried roots with bare-call pairs: the first answer was absent from every root and from `turns[]`. No +throw, no diagnostic, and the model's only sensible response is to re-issue the call — the exact loop this +unit exists to end, reintroduced by the fix for the previous round's blocker. + +`tests/cursor-blob.test.ts` uses that bare-call shape in nine fixtures, so this was not an exotic input. + +Two separable defects sat in the same place. The drop was also unnecessary: `historyLimit` subtracted +`systemEntryCount` on the checkpoint path, where the caller appends only `ids.slice(suffixSystemCount)` and +the checkpoint's own system roots are already inside `carriedRoots.count`. One free slot was charged twice, +so at 190 carried roots the limit came out 1 where 2 results fit. + +Both are fixed at the origin of the mismatch rather than at the call site. `rootPromptMessages` now returns +`activeMessageIndexes` — the trailing run as pruning saw it, recorded before pruning can shrink it — and the +abandon check reads that instead of re-deriving a run it cannot see correctly. It falls back to the +raw-space scan when the field is empty, which is how the full-replay and native shapes keep their previous +behaviour. `chargeableSystemCount` is zero on the covered-turn path, closing the double charge. + +Measured after the fix: 24 bare-call configurations across carried 170-190 and 2-8 pairs lose no answer at +all, and the reclaimed slot is visible — 192 roots where the defect emitted 191. + +### Mutation evidence, including one gap this caught in its own first attempt + +- abandon check re-derives from raw space → 2 red +- system count charged twice → 1 red +- the round 5 count bound removed → 5 red + +The middle row is worth keeping. The first version of the silent-loss test passed with the double charge +still in place, because that defect abandons the checkpoint and a full replay carries every answer — correct +output, reached wastefully, which no assertion about answer presence can distinguish. It took a second case +asserting the exact root count at exact fit to pin the arithmetic. A test that cannot fail against the +defect it was written for is the thing five of these six rounds actually kept finding. + +Round 6 also found that `outputElided` on the marker-only truncation return had no coverage: removing the +flag left all 191 tests green, and `tests/` is outside `tsconfig`'s `include`, so nothing else would have +noticed either. Covered now by asserting the abandonment it is supposed to trigger. + +Four-suite total is 197 pass / 0 fail; `cursor-blob` alone 111. + +## Audit round 7: the repetition note stopped the walk that protects the results + +The trailing-result walk tested one thing — `role === "toolResult"` — and walked backwards from the very end +of `history`. The repetition breaker appends a synthetic `[context note]` **user** root after the transcript +when the same output repeats three times or more. That note stands for no message, so it carries no +`messageIndex`, and the walk hit it immediately and stopped: `activeStart === history.length`, the trailing +run came out empty, `activeMessageIndexes` came out `[]`. + +Two failures at once, both worse than the defect round 6 fixed: + +The results lost trailing-run status altogether. They fell through into `prior` and were pruned as ordinary +history, so the "keep at least one result" floor never applied to them. + +And the empty `activeMessageIndexes` sent the abandon check into its raw-space fallback — the exact scan +round 6 exists to avoid. Measured: at 186 carried roots the note-armed shape was RETAINED where the +identical shape without the note correctly abandoned to a coherent full replay. + +The trigger is the worst possible one. The note arms on three consecutive identical assistant narrations, +which is the runaway-repetition shape this entire unit exists to end — so the input most likely to hit the +defect is the input the fix was written for. + +Instrumented state at the moment of the break: + +``` +PRUNE {historyLen:10, activeStart:10, active:0, activeIdx:[], historyLimit:6, lastRole:"user"} +ABANDON {activeIdx:[], usedFallback:true, trailingIndexes:[19], keptEnough:true} +``` + +`activeStart` equal to `historyLen` is the whole bug in one number. + +The walk now skips trailing roots that carry no `messageIndex` before looking for the result run, and the +excluded roots are re-appended afterwards so the note itself still reaches the model. That re-append is the +part that needed care: a root added after pruning has to be paid for DURING pruning, or the envelope is +overrun by exactly its number. Left uncharged, note-armed continuations at 188-190 carried roots threw the +non-retryable 400 for both sequential and parallel suffixes. `syntheticCount` and `syntheticBytes` are +therefore charged in the count bound, in the prior-history admission loop, and in the byte accounting, and +the orphan-strip floor counts them too so the strip cannot eat into the trailing run. + +### The byte relaxation was dropped rather than covered + +Round 7 also found that `chargeableSystemBytes = 0` had no coverage: reverting it alone left all four suites +green. The double-charge argument applies to bytes in principle, but no configuration could be found where +relaxing it changes the assembled payload — six crossings of carried bytes against system size against +result size in the deciding band produced byte-identical output either way. So it is gone. Charging the +system bytes twice only ever errs conservative, and untested new code on the envelope path is a liability, +not a saving. The count relaxation stays: it is covered, and its own case reddens without it. + +### Mutation evidence + +- the `messageIndex` walk removed (r11 defect restored) → 1 red +- `syntheticCount` uncharged in the count bound → 1 red +- the note dropped from the payload instead of re-appended → 1 red +- `syntheticCount` uncharged in the prior-history loop → 2 red + +The middle two are why this round's first attempt was not finished: both charges initially had no failing +test, exactly the condition round 6 had already been caught on once. A 224-configuration count sweep across +carried 185-191 by note-armed sequential and parallel suffixes showed the uncharged version throwing and the +charged version clean, which is what the new boundary case now asserts. + +Four-suite total is 198 pass / 0 fail; `cursor-blob` alone 115. Sweeps re-run clean at this head: 1440 +configurations across narrated, bare-call, whitespace-text and parallel shapes with zero envelope overruns, +zero orphaned calls and zero lost newest results; 78-position count-by-parallel grid clean; all five +multi-turn growth shapes survive 200 turns. + +## Audit round 8: the note was inside the array every pruning block reasons about + +Round 7 re-appended the note into `historyEntries` before the pruning blocks ran, and from that point every +one of them had to recognise a tail it could only identify by position. The initiator-recovery block could +not. Its floor is "stop when one entry is left", so with `[toolResult, note]` it counted the note as the +survivor and shifted off the **result**. + +What reached the model, one 600 KB result, three identical narrations instead of two the only difference: + +``` +PLAIN roots=3 lens=[16, 24, 524067] <- the answer +ARMED roots=3 lens=[16, 24, 193] <- the note, and nothing else +``` + +193 bytes of "take a DIFFERENT action" in place of the output the model was waiting for. The result had +already been truncated to fit; the recovery block deleted it anyway. This is the reported symptom exactly — +no tool output, so the model runs the command again — re-entered through the fix for it. + +A second mechanism compounded it. `activeBytes` included `syntheticBytes` while the equal-share divisor did +not, so shares summed to the entire budget and adding the note back always exceeded it. The +shrink-toward-equal-share pass — whose whole purpose is "a missing result is worse than a truncated one" — +became structurally unfittable, and control fell through to the loop that deletes a whole result. 246 bytes +of note cost a 200 KB answer. Reviewer measured 166 of 432 byte-pressure configurations losing an answer. + +### The fix is structural, not another floor + +Adding `+ trailingSynthetic.length` to each floor would have worked and would have left the next block to +discover the same trap. Instead the tail is held **out** of `historyEntries` entirely until assembly, and +every budget below is expressed net of it: `historyLimitForReal` and `historyBudgetForReal` are computed +once, before the first result is measured. The pruning blocks then reason only about real history and cannot +mistake one kind of root for the other, and the reservation is what keeps the tail from overrunning the +envelope when it returns. + +That the reservation is load-bearing was proved twice over: with it removed the same shapes 400 on the byte +limit, and an intermediate version that held the tail out without reserving its bytes committed 51 bytes +over. + +### Coverage, which was the round's second finding + +The entire `syntheticBytes` charge family had no test: neutralizing it in one edit left the suite green +while a sweep against that mutation threw 148 envelope errors. That is the third uncovered hunk in this +unit, and it landed in the same commit whose message drops `chargeableSystemBytes` for being uncovered — +the argument was made and then not applied to the new code beside it. + +Mutation evidence at this head: + +- byte reservation removed → 2 red +- count reservation removed → 3 red +- note dropped from the payload → 4 red +- `messageIndex` walk removed (r11 defect) → 3 red +- note re-appended into `historyEntries` **and** the gross budget spent (r12 defect in full) → 2 red + +The last row is worth stating precisely: re-appending alone is now harmless, because the reservation +prevents the loss on its own. The defect needed both halves, and the test catches the pair. + +Four-suite total is 201 pass / 0 fail; `cursor-blob` alone 118. Sweeps at this head: 896 note-armed +configurations across four assistant shapes crossed with count and byte pressure, 1440-case +call-answer-invariant sweep, 224-case count sweep, 78-position grid — zero overruns, zero orphaned calls, +zero lost answers, zero notes lost. Five multi-turn growth shapes survive 200 turns. + +### What eight rounds actually found + +One defect, re-entering through each of its own fixes. Every round's patch was correct for the path it was +written against and silent about a sibling path in the same condition — and three times the sibling was +created by the previous fix. The through-line is not carelessness about the condition; it is that each fix +added a fact to the pruning code (`carriedRoots`, a count bound, a root-space run, a synthetic tail) without +asking which existing block already assumed that fact absent. The last fix is the first that removes a +distinction rather than adding one. + +## Audit round 9: a subtraction clamped at zero cannot say "unaffordable" + +The reservation was `Math.max(0, historyBudget - syntheticBytes)`, and the tail was appended +unconditionally. Those two facts are compatible only while the difference is non-negative. Below that the +clamp reports "the note costs nothing", every pruning block correctly reasons about a budget of zero and +emits nothing, and the note is appended anyway — so the payload lands over the limit by exactly the deficit +the clamp erased. With 26 bytes free and a 246-byte note, 220 bytes over and a non-retryable 400. + +Holding the tail out of `historyEntries` is what made it unrecoverable. No block below could see it, so +none could charge it. + +Ninth iteration of the same pattern, and this time the new fact was *the tail is always appended*; the +construct that assumed otherwise was the clamp introduced beside it. + +### Why every fixture missed it + +The exposed shape is a turn that does **not** end in a tool result — an ordinary user interjection after a +repetitive stretch. With a trailing result the abandon check's survival disjuncts fire and rescue the turn; +on a plain follow-up they structurally cannot, and nothing else bounded the tail. Every fixture in +`cursor-blob` is a tool continuation. Measured across 42 carried-byte positions: 13 throws with the note +armed, 0 without, all on the interjection tail. + +The note is now dropped when it cannot be paid for. That is this unit's own priority order, stated in the +round 8 record and applied here: a missing instruction is recoverable, a missing tool result restarts the +loop. + +### One inert condition removed rather than shipped + +The first version of the affordability test also required a free root slot. It could not be made to matter: +60 boundary positions at and past the root limit behaved identically with and without it, because the count +bound already stops at one surviving result. It is gone. Byte affordability alone decides. + +That is the second time in this unit an inert guard was written and then dropped, and the reason is worth +recording: an envelope condition that cannot fail is indistinguishable from one that is wrong, so keeping it +costs the next reader the same audit it cost this one. + +Also corrected: one `activeBytes > historyBudget` gate still read the gross budget while its body wrote the +net one. Provably no behavioural difference — the entry has already been truncated to net by then — but it +is the exact drift that seeded rounds 5 and 6. + +Mutation evidence: affordability removed → 3 red; tail appended regardless of affordability → 3 red. + +Four-suite total is 208 pass / 0 fail; `cursor-blob` alone 122. Every sweep re-run clean at this head: 42 +deficit positions, 60 count-boundary positions, 150 zero-budget boundary cases, 896 note-armed +configurations, 1440-case call-answer invariant, 224-case count sweep, 78-position grid, 24 bare-call cases, +and five multi-turn growth shapes surviving 200 turns. + +## Audit round 10: the guard removed as inert was load-bearing at exactly one value + +Round 9 dropped the count half of the affordability test, arguing that the count bound below always leaves a +slot free because it keeps one result. That is true for every value of `historyLimit` except 1 — where the +one free slot is precisely the one the surviving result takes. The note was then judged affordable on bytes +alone, the reservation clamped to zero, and the append pushed full replay to 193 roots. + +Four armed-only `CursorRootEnvelopeLimitError` throws at 191 system prompts, across both tails and both +suffix widths, where the same request without the note assembled 192 and succeeded. Full replay has no +abandon branch, so nothing rescued it. + +The reasoning error is worth naming precisely, because the sweep that supported it was real. It varied +**carried roots on the checkpoint path**, where the count-full disjunct abandons the checkpoint long before +`historyLimit` can reach 1. The reachable route is full replay with many system prompts — a different axis +entirely, and one no earlier round had needed. "Inert across 60 positions" was a true statement about the +wrong sixty. + +Both conjuncts are restored. The lesson is not that removing inert guards was wrong; it is that "inert" +needs the axis that can make it fire, and a sweep along one axis does not establish it along another. + +### The reservation was uncovered, distinctly from the append + +Round 9's own mutation table claimed the affordability check was covered. It was covered at the **append** +site only: neutering `syntheticCount`/`syntheticBytes` while leaving `trailingSynthetic` gated left the +suite green, because asserting on the assembled payload cannot separate "the deficit was charged" from "the +tail simply was not appended". Asserting the exact root count at the boundary does separate them, and that +case is now present. + +Mutation evidence at this head, each applied alone: + +- count conjunct removed (the r14 defect) → 4 red +- byte conjunct removed (the r13 defect) → 3 red +- reservation neutered, append still gated → 6 red +- append ungated → 7 red + +Four-suite total is 212 pass / 0 fail; `cursor-blob` alone 126. + +### Ten rounds, one shape + +Every round found the same class of defect: a fact added to the pruning code beside a construct that assumed +it absent. Rounds 5 through 10 were each triggered by the previous round's own fix. Two of those were +arguments about whether a guard could fire — one dropped correctly, one dropped wrongly and restored here — +which suggests the code's real difficulty is that its budget arithmetic has several axes and any single sweep +silently fixes all but one of them. + +## Audit round 11: PASS, and the two notes it left + +Round 11 found no blocker. It confirmed `syntheticCountRaw` can only be 0 or 1 — one push site, once per +request — so the conjunct reduces to `historyLimit >= 2` when the note exists, and checked that threshold in +both directions: at 1 the single free slot belongs to the result, at 2 both fit exactly at 192 roots. It +audited all 25 budget references and found gross values only in the affordability test itself, which is +where they belong. Across 5040 checkpoint configurations and 200-turn feedback growth at five call widths: +no throw, no overrun, no lost newest result, no orphaned call. + +Its attribution rig is the more useful artifact. Driving HEAD, the parent, and base `dev` through identical +576-position grids: HEAD is never worse than its parent anywhere, and the 8 positions where HEAD throws and +`dev` did not are all 192 system prompts, where the prompts alone exceed the envelope and HEAD throws with +or without the note. On those same positions `dev` emitted 192 roots carrying **zero** tool results — the +re-run loop this unit exists to end. Totals: HEAD 104 throws / 232 newest-lost, parent 112 / 232, `dev` +96 / 372. + +### The threshold is now pinned from the tight side too + +Round 11's one actionable note: tightening `>= 1` to `>= 2` left all 212 tests green. Over-conservative is +safer than over-eager, but a suite that cannot tell a correct bound from an unnecessarily strict one is +exactly the gap that cost round 14. A case at two free slots now asserts that the note and the answer both +arrive at exactly 192 roots: relaxing the bound reddens 4, tightening it reddens 1. + +### A claim in the round 10 record was wrong + +That record said the reservation had been pinned at the append site only, and that neutering +`syntheticCount`/`syntheticBytes` left the suite green. On the parent commit that mutation already reddens +6, all of them pre-existing round 8 and 9 cases. The count-conjunct finding stands on its own evidence; this +secondary claim did not, and the root-count case is not what closed it. + +### Remaining known gap, scoped out deliberately + +On the extreme byte axis — a single system prompt near 523 KB — the note can be kept while the result +truncates to a marker, which inverts this unit's stated priority order. That band is identical on the parent +(24 positions) and far worse on `dev` (180), so it is pre-existing and improved here rather than introduced. +Full replay has no abandon branch to rescue it, which makes it a genuine follow-up rather than a +non-problem, and it belongs to its own phase. + +Four-suite total is 213 pass / 0 fail; `cursor-blob` alone 127. + +## Terminal outcome + +PR #2940 landed on `dev` as squash commit `62df78d8dd2451accdc0ddd615b9fad080d64a60`, from head +`0340d17599b65dda8b739a30107f59297e0d145b`, with CI green at that exact head. The remote gate on +`ssh lidge` was re-run against the merge commit itself and reported exit 0 with 16359 pass / 0 fail / +16 skip, so the landed tree is verified rather than only the pre-merge head. + +Round 11 is the closing verdict: PASS, with two minor notes, both addressed in `0340d1759` before the +merge — a threshold case pinned from the tight side, and the correction of a wrong secondary claim in +the round 10 record. Rounds 1 through 10 each found a genuine blocker, and rounds 5 through 10 were +each triggered by the previous round's own fix. That is the finding worth carrying forward: every one +of those fixes added a fact to the pruning code without asking which existing block had assumed that +fact absent. + +Three items were scoped out on purpose and are not defects of this unit. The `envelope_exhausted` +reason still does not reach the checkpoint store, and the spread copy in `live-transport.ts` makes it +provably inert rather than merely unobserved; propagating it needs a signature change on a shared +prepare path. On the extreme byte axis near a 523 KB system prompt the repetition note can survive +while the result truncates to a marker, which is pre-existing and measurably better here than on the +parent. And `composer-2.5` assembles 194 roots because it is a hybrid — `echoToolResultInRoot` true +with `externalModel` false — which places it outside the envelope guard; that behaviour is identical +on `dev` and predates this work. + +This unit moves to `_fin` under the rule in `AGENTS.md`: the work it records is now visible in public +git history. diff --git a/devlog/_fin/260829_cursor_tool_continuation_pairing/080_final_gate.md b/devlog/_fin/260829_cursor_tool_continuation_pairing/080_final_gate.md new file mode 100644 index 0000000000..732fcb4a21 --- /dev/null +++ b/devlog/_fin/260829_cursor_tool_continuation_pairing/080_final_gate.md @@ -0,0 +1,78 @@ +# 080 — Final gate: independent audit of the landed fix + +Reviewed tree: `7747bf74f`, checked out detached and clean, which at the time was `origin/dev`. +The fix path and this unit are byte-identical at later heads, so the audit still describes them. + +## Why a separate gate, after eleven rounds + +Rounds 1 through 11 in `070` audited the change while it was being built, against a plan the same +session wrote.

It does +not emit a separate assistant `[Tool Call]` root before the result. It names the invocation *inside* +the result envelope, as an `invoked: with ` line +(`src/adapters/cursor/protobuf-request.ts`).

System roots are all retained before the history budget is +computed (`:309-380`), and trailing active tool results are byte-pruned but never +count-pruned. + +Reproduced in isolated probes: 193 roots from 193 system prompts; 614,430 root bytes +from a single 600 KiB system prompt; 194 roots from one system plus 193 trailing +results. Each reported `continuationMode: "full-replay"`. + +Two further escapes the first draft missed: + +- **Cumulative checkpoint roots (blocker 9).** Suffix roots are appended AFTER + existing checkpoint roots (`:937-947`) but `rootPromptMessages` sees only the + suffix. A probe with 192 checkpoint roots plus a two-root suffix emitted 194. +- **The empty-history early return (blocker 10).** `rootPromptMessages` returns + before external enforcement when `rawMessages` is empty (`:198-215`). A guard + placed only in the external-history branch leaves this path unbounded; a probe + emitted 193 system roots through it. + +Both mean the guard cannot live inside `rootPromptMessages`. The final root set +exists only after checkpoint or full-replay assembly completes (`:959-974`), and +that is where enforcement belongs. + +## Defect 2 — a tool result can be sent without the request that caused it + +External replay omits assistant tool-call roots by design (`:288`). The pruner puts +every trailing tool result into `active` (`:321-326`), so one large result can +consume the whole history budget and drop the preceding user turn (`:348-357`). The +orphan guard preserves that lone result and sets `historyMessageStart` to it +(`:365-369`); `conversationTurns()` then finds no current user turn and drops it from +`turns[]` too (`:719`, `:763`). + +The emitted request is system roots, an assistant-role tool-result marker, zero turn +blobs, and the generic Continue action. The audit's one correction to the framing: +it is not literally instruction-free — system instructions and the Continue action +are present. What is missing is the initiating user instruction, which is what makes +a large-context turn answerable. A model given that answers in a handful of tokens, +matching the report (200 OK, 4-19 output tokens at 80-95k input), reproduced with no +Cursor account. + +`tests/cursor-blob.test.ts:474` asserts the oversized result and its truncation +marker survive. It never asserts the initiating turn survives, which is why CI stayed +green over a request shape that cannot work. + +## Blocker 8 — why the obvious rule was wrong + +The first draft said: never emit a result-only continuation. That is correct for full +replay and WRONG for checkpoint continuation. Production sets `checkpointSuffixStart` +to the covered message count (`src/adapters/cursor/request-builder.ts:479-488`), so a +valid suffix may legitimately begin with a tool result — the initiating turn is +already inside the checkpoint. `rootPromptMessages` receives only the sliced suffix +(`:915-933`) and cannot recover it, so a blanket rule would reject or corrupt correct +continuation. + +The distinction must be an explicit argument, not inferred from message shape. Pass a +replay origin: `"checkpoint-covered"` only from the branch where checkpoint decoding +succeeded (`conversationState` established at `:917-918`) and `checkpointSuffixStart` +passed validation (`:919-926`); `"full-replay"` from every fallback path (`:959-960`). +Do not derive it from the advisory `request.continuationMode`. + +## Change map + +### `rootPromptMessages` — replay origin + +Accept an explicit origin (`:198-204`). + +Full replay retains the initiating user or developer root together with every +contiguous trailing tool-result root; if that group cannot fit, fail rather than emit +a result-only replay. Checkpoint-covered replay may begin with tool results. + +### `rootPromptMessages` — atomic tool-result block (blocker 11) + +The first draft's "atomic block" contradicted the 192-root cap: 193 results plus a +system root cannot be both. Atomicity means MEMBERSHIP: every result present in +original order, or construction fails. Explicit text truncation of a result may +remain, but whole-result deletion — `shift`, `filter`, marker omission — is forbidden +(`:318-341`). A count-only assertion would let an implementation silently drop +results and still pass, so tests assert result IDENTITY, not just count. + +### `buildPreparedCursorRunRequest` — one measurement, one guard + +Immediately after `conversationState` is final (`:959-994`), measure +`rootPromptMessagesJson` once: `rootCount` from the final ID list; `rootBytes` as the +sum of stored blob lengths, counting repeated IDs repeatedly; fail closed if any final +ID is unmeasurable. For external models, reject when count exceeds 192 or bytes exceed +512 KiB. Use this same measurement for the `run-request` telemetry. + +This single site fixes blockers 9 and 10 together: it sees checkpoint roots plus +suffix, and it is downstream of the empty-history early return. + +### `native-exec.ts` — blob size accessor + +Add a read-only `cursorBlobByteLength(blobId)` over the existing store +(`:333-340`, `:457-459`), returning stored byte length and never content. Requiring +resolvable sizes is safe because committed checkpoints already fail when a referenced +blob cannot be pinned (`src/adapters/cursor/checkpoint-store.ts:220-228`). + +### `cursor-errors.ts` — typed failure (blocker 12) + +Add `CursorRootEnvelopeLimitError` following the existing typed-error pattern +(`:36-71`): stable `name`, `code = "cursor_root_envelope_limit"`, `status = 400`, and +readonly `rootCount`, `rootBytes`, `maxRootCount`, `maxRootBytes`. Classify as an +invalid Cursor request. Add `CursorRootMeasurementError` for an unmeasurable final blob rather than logging +an invented number (re-audit blocker 6, which correctly noted the first revision left +it undefined): `code = "cursor_root_measurement_failed"`, `status = 500` because it +is an internal accounting failure rather than an oversized client request, carrying +the unmeasurable blob id and the count measured so far. It maps through the adapter +with the same non-retryable discipline. + +`isRetryableCursorError` returns false for both classes before any text heuristic +(`transport-retry.ts:20-39`) — retrying an over-envelope request only reproduces it. +The terminal catch in `src/adapters/cursor.ts:477-488` preserves status 400, +`invalid_request_error`, the code, and `retryable: false` instead of degrading to a +message-inferred 502. + +### Telemetry (blocker 13) + +The first draft called telemetry defect-free. It is not. For a pure checkpoint, +`rootPromptMessagesState` is undefined and `:990-992` reports `rootBytes: 0` despite +real checkpoint roots. For suffix replay, `:948-953` records `suffixRoots.byteLength` +including a synthetic system root that was then removed. Both are fixed by reporting +the single final measurement above — which matters beyond observability, because the +blocker-9 guard depends on the same number being right. + +Also drop the synthetic default-system root from suffix assembly (`:927-953`) so +suffix accounting stops including a root absent from the final envelope. + +## Accept criteria + +1. **Full replay keeps its initiating turn.** External full replay under cap, one + initiating user root, uniquely identified trailing results: the final non-system + sequence is the initiating user followed by every expected `call_id` in order. + Mutation: classify the call checkpoint-covered, or drop the initiating root — red. + (b) **Developer-root initiator (re-audit 5).** The same case with a `developer` + root as initiator. Turn discovery currently scans for `user` only + (`protobuf-request.ts:346-351`) even though its own comment says user or + developer, so a user-only test would pass an implementation that still drops a + developer-initiated turn. Fix the scan and assert the developer root survives. +2. **Checkpoint-covered result-only suffix stays valid.** A pinned checkpoint covers + the initiating turn and the suffix slices to a tool result: checkpoint roots + remain, the result is appended, no synthetic system root appears. + Mutation: apply the full-replay rule to the suffix — rejects or loses the result, + red. This is the blocker-8 regression guard. +3. **Count guard is cumulative.** 192 checkpoint roots plus a two-root suffix throws + with `rootCount === 194`. Mutation: guard only `suffixRoots` — no throw, red. +4. **Byte guard is cumulative.** Under 192 roots whose hydrated final bytes exceed + 512 KiB throws, and `rootBytes` equals the independently hydrated sum. + Mutation: count-only, or suffix-local byte accounting — no throw, red. +5. **The early return cannot bypass enforcement.** 193 system prompts with no + `rawMessages` throws with `rootCount === 193`. Mutation: guard only the + external-history branch — serializes fine, red. +6. **Tool-result membership is all-or-fail.** (a) An under-cap block with unique + `call_id`s keeps every identity and order. (b) 193 active results plus one system + root throws rather than emitting a shortened envelope. + Mutation: restore `active.shift()` or any arbitrary deletion — identity or + rejection assertion red even though the count still fits. + (c) **Combined byte overflow (re-audit 4).** Several results, each individually + representable, whose combined block exceeds the budget — the only shape that + reaches the deletion loop at `protobuf-request.ts:328-330`. Assert every result + identity survives or the request is rejected; never a silently shortened block. + Without this case the `active.shift()` mutation is NOT red, because 193 small + results stay under the byte budget and get caught by the count guard instead — + the re-audit's correction. +7. **Byte truncation cannot erase a result.** When the system leaves less room than + the minimum result-plus-marker representation, throw. Mutation: restore the + current omission path (`:332-340`) — succeeds without the result, red. +8. **The typed failure carries evidence.** Assert class, `name`, `code`, + `status === 400`, exact measured counts, both limits, and + `isRetryableCursorError(error) === false`; then the same class through the adapter + for event status, type, code, retryability. + Mutation: throw a generic Error, omit measured fields, or match on message regex + — at least one assertion red. This is what makes blocker 12 non-vacuous. +9. **Telemetry equals the final envelope.** (a) Pure checkpoint with debug enabled: + `rootBlobs` and `rootBytes` equal the hydrated checkpoint roots, not zero. + (b) Checkpoint plus suffix: telemetry equals the final sum and excludes the removed + synthetic system root. + Mutation: restore `rootPromptMessagesState?.byteLength ?? 0` or + `suffixRoots.byteLength` — red. +10. **An unmeasurable root is counted, not fatal (corrected during build).** A root + carried inside a decoded checkpoint need not exist in the local blob store — + Cursor minted some of them, and a resumed conversation legitimately references + ids this process never wrote. The count limit still binds such a root; the byte + total becomes a floor, and `unmeasuredRoots` in the diagnostic says so. + Mutation `unmeasured-fatal` (throw on an unmeasurable root) — red, 5 fail. +11. Invalid checkpoint bytes still report `continuationMode: "full-replay"` with + `checkpointInvalidationReason: "decode_failed"`. +12. Valid tool-suspended checkpoint continuation does not regress. + +## Corrections made during implementation + +Two things in the plan above were wrong and were changed rather than implemented as +written. Both were caught by running mutations, not by reading. + +**`CursorRootMeasurementError` was designed and then deleted.** Criterion 10 +originally required failing closed on an unmeasurable root. Implementing it broke +three already-passing checkpoint tests, which is the evidence that failing closed +rejects working continuation: checkpoint roots are *expected* to be absent from the +local store. With the fail-closed branch gone the class became unreachable, and an +unreachable error class cannot be tested, so it is not in the shipped diff. The +reasoning is recorded next to `isCursorRootEnvelopeError` so the next reader does not +re-add it. + +**The `replayOrigin` parameter was removed as non-load-bearing.** The plan gated +orphan-result recovery on whether the call was a full replay or a checkpoint suffix. +A mutation that forced the suffix branch could not be made red — `activeStart > 0` +already confines the search to the current call's slice, so the flag never decided +anything. Worse, gating on it would have *recreated* the defect for a checkpoint +suffix that does contain its own initiating turn. A parameter that cannot be observed +is not a safeguard. + +## Verification + +`bun test tests/cursor-blob.test.ts tests/cursor-request-builder.test.ts +tests/cursor-transport-retry.test.ts`: 153 pass, 0 fail. `bun x tsc --noEmit` clean. +CI on the exact PR head is primary; the request path is shared, so the merged tree is +verified before merge.

It does not hash `$CODEX_HOME/AGENTS.md`. + +`probePromptText` runs the child with `cwd = resolveCodexHomeDir()` +(`src/codex/prompt-text-probe.ts:400`) and extracts that file's body as the +`__agents_md` layer (`:365`). The fingerprint is a component of `commandKey()` +(`:137-145`), which is the sole admission identity in `runSharedPromptProbe` +(`:302`). So an `AGENTS.md` edit leaves the key unchanged, the next request matches +`active.key`, joins the in-flight pre-write probe, and is served pre-write text. + +Reproduced deterministically at `a7504ab8e`: identical fingerprints before and +after the write, and both callers received `"old-agent-text"`. + +This is the same class of bug the fingerprint was introduced to fix. The original +`revision` covered only config/store transaction bytes, so editing the selected base +variant changed the prompt without moving the revision. Naming one more uncovered +input does not change the shape of the defect: admission identity must name every +input the probe renders. + +## Fix + +Hash the `CODEX_HOME` instruction files into the fingerprint. + +The path is `resolveCodexHomeDir()`, **not** `dirname(activeConfigPath(opts))`. The +plan audit rejected the latter and it is right: `tests/codex-prompt-route.test.ts:115-125` +injects `codexPromptPaths` at a fixture root while setting `CODEX_HOME` to a separate +decoy, precisely so a route that ignored the injected paths is caught. Deriving the +`AGENTS.md` path from `configPath` would name a file the probe never reads, and the +regression would pass while production stayed broken. + +Both spellings are hashed, in Codex's own precedence order: `AGENTS.override.md` +is preferred over `AGENTS.md`, so an override edit must move the key too. Absent +files hash to a distinct sentinel, so create and delete both move the key. + +## What this does not cover, stated rather than implied + +The guarantee is bounded to OpenCodex-managed writes plus the `CODEX_HOME` +instruction files. It is not complete prompt-state identity, and the code says so +instead of implying otherwise: + +- Skill metadata, plugin manifests, and MCP/app availability feed + ``, `` and ``. +- Clock, timezone, shell and permission state feed ``. + +None is writable through `/api/codex-prompt`; each needs an external edit +concurrent with an in-flight probe. A 15-second window bounded by a fail-closed +`busy` is the exposure, and pretending to fingerprint a clock would be worse than +documenting it. + +The external `model_instructions_file` target was on that list and has been moved +off it. Listing it there was the wrong call twice over: it is an ordinary file this +process can read, and leaving it out meant the guarantee depended on whether we +authored the selected base prompt. A fourth review round found the asymmetry — +managed variant bytes hashed, an external selection recorded as the bare word +`external`. Its path and bytes are now hashed like any other field. + +One correction to that round's stated impact, because the difference matters for +anyone reading this later: `base-instructions` is reported `not-exposed` +unconditionally, since `prompt_debug.rs` discards it. So the stale value was never +rendered back to a caller. The defect was a real hole in admission identity, not an +observable stale layer, and it is worth closing on the first ground alone. + +## Round-by-round record + +Four review rounds, four real defects. Worth keeping because the pattern is the +point: each fix was itself reviewed, and three of the four findings were in code +written to fix the previous finding. + +1. The fingerprint omitted `AGENTS.md` entirely. +2. Fields were concatenated unframed, so contents could imitate a separator; the + `\0absent` sentinel collided with a file holding those literal bytes. +3. `computeRevision` still had that same unframed shape inside it — and that value + is also the write-path concurrency token, so the collision reached further than + the probe. +4. An external base selection was hashed as a bare kind string. +5. Two more: a relative `model_instructions_file` was resolved against the proxy's + own working directory instead of the config file's, so it hashed an unrelated + file; and only the two built-in project-document names were considered, so a + configured `project_doc_fallback_filenames` entry could be edited unnoticed. + +## The pattern, and where it stops + +Five rounds is the interesting part of this record. Each fix was reviewed, and four +of the six findings were in code written to close the previous finding. The reason is +consistent: a cache key is only as good as its worst-covered input, and "I added the +input I was told about" is not the same as "the key names everything the output +depends on". Framing, path resolution, and candidate-set breadth each failed +separately. + +A sixth round then rejected the first version of this very section, and it was right. +It claimed the ancestor walk could never find anything because the probe runs in +`CODEX_HOME` with no checkout around it. The default project-root marker is `.git`, +and `~/.codex` inside a dotfiles repository is an ordinary setup: there, Codex renders +the repository's own `AGENTS.md` and the walk matters. The same round found two more +parsing gaps — upstream trims each configured filename and drops whitespace-only +entries, and the ordinary multi-line array spelling was missed by a single-line regex. + +So the walk is now performed rather than argued away: nearest ancestor holding a +configured marker, then every directory from that root down to the home, with a +present-but-empty `project_root_markers` disabling detection exactly as upstream does. + +An eighth round then rejected this section a second time. Skill metadata had been +written off as "a directory tree with no stable enumeration contract"; a live edit to +one `SKILL.md` description moved the probe's rendered output while the fingerprint +stood still. It is a directory listing and one file read per skill. The manifests are +hashed now. + +What remains uncovered: + +- **Plugin manifests and MCP/app availability.** Availability is a live connector + state, not a file this process can stat. +- **Clock, timezone, shell.** Not files. A fingerprint over a clock is not a + fingerprint. + +The exposure is an external edit landing inside a single in-flight probe's window. Be +precise about the failure mode, because an earlier draft of this sentence got it +backwards: for an input the key does not cover, the key does not move, so the caller +DOES join and DOES receive the older rendering. Fail-closed `busy` is what happens for +a covered input. An uncovered one is a stale read of one layer's text, bounded to that +window, in a read-only inspection view. + +This section has now been wrong twice, in the same direction both times: something was +called unreadable when it was merely inconvenient to read. The standard that survived +is narrow — an input belongs on this list only when no file on disk determines it. +Anything with a path gets hashed. + +## Why this is a bounded key and not a total one + +Nine rounds in, the useful conclusion is about the shape of the specification rather +than any single input. "Hash everything the rendered prompt depends on" is closable +only against a pinned Codex: the dependency graph belongs to Codex, is private, and +moves independently of this repository. A new config field or a changed precedence +upstream silently widens the gap without anything here changing. + +So this is a bounded invalidation key over known local inputs, and the code says that +rather than implying identity. + +A design that needs no enumeration exists and was assessed: admit on TIME, where a +request may join a probe only if the probe started after the request arrived. The +correctness argument holds — such a probe read the filesystem after every write that +completed before the request — and it needs a monotonic in-process ordinal rather than +a clock. It was not adopted because it removes almost all the coalescing that motivated +the work: a probe spawns immediately, so the ordinary second caller arrives after the +start and would always be refused. Recovering both properties means cohort batching — +hold arrivals briefly, spawn once the cohort is closed — which is a different change +from this one. + +That is a real option, not a dismissal, and it belongs to whoever needs a strict +"never older than my arrival" contract. What ships here is the bounded key, which is +strictly better than the revision-only key it replaces. + +## The reader, and why it stopped being a regex + +Rounds five, six and seven each found another valid TOML spelling the hand-rolled +reader missed: a multi-line array, then a comment directly after the opening bracket, +then a quoted key. Three rounds, three patches to the same regex, each closing one +spelling and leaving the rest. + +At that point the pattern was the defect. TOML is not a line format, so no regex over +lines can enumerate what a parser accepts, and each fix was only ever going to cover +the example in front of it. `Bun.TOML.parse` reads both keys now. + +The module header forbids trusting a JS TOML parser, and that prohibition is worth +not eroding, so the distinction matters: it is about VERIFYING BYTES WE WRITE, where +Bun and Rust `toml_edit` disagree on escapes and Codex reads what we wrote. This is a +read of two arrays of plain filenames, and the failure directions are opposite. A +parse disagreement here costs a redundant probe; a missed spelling costs a stale read. +An unparseable file yields nothing, which is correct — Codex could not load it either. + +## Verification + +Route-level, in the file whose fixture separates `CODEX_HOME` from the injected +paths — the only place this can fail honestly. Two callers separated by an +`AGENTS.md` write must not share a flight: the second returns `busy`, and a later +request returns the new text. Repeated for `AGENTS.override.md`. + +Named mutation: delete the instruction-file contribution from the fingerprint. The +regression must go red with identical keys and one spawn. diff --git a/devlog/_plan/260829_bugpr_lane_h_residual_issues/140_pr2884_shim_backup_matcher.md b/devlog/_plan/260829_bugpr_lane_h_residual_issues/140_pr2884_shim_backup_matcher.md new file mode 100644 index 0000000000..71ffe76685 --- /dev/null +++ b/devlog/_plan/260829_bugpr_lane_h_residual_issues/140_pr2884_shim_backup_matcher.md @@ -0,0 +1,94 @@ +# 140 — #2884: match the shim's launcher backups, and only those + +Contributor PR #2884 reported a real defect with `ps` output from an affected host.

The generic OAuth replay cannot pick it up either — that +branch is limited to xAI, GitHub Copilot, and Kiro (`:3020-3024`). `/v1/responses/compact` +carries the identical gate (`src/server/responses/compact.ts:679-686`). + +So the `401` falls through to terminal handling, is classified `credential` +(`src/codex/routing.ts:349-367`), and that branch marks reauth and removes every +affinity entry for the account (`:2146-2157`). + +`/v1/chat/completions` bridges into `handleResponses` +(`src/server/chat-completions.ts:242`), so fixing core covers it too. + +One correction to the report's wording: `needsReauth` is a process-local `Set` +(`src/codex/account-runtime-state.ts:3-10`), not a persisted credential-store field. +The account recovers on restart. That makes the defect less severe than "stored account +corrupted" and no less real — inside a running proxy the account is out of rotation and +its affinity is gone. + +## What gets built + +The machinery exists; ordinary pool has more of it than main does. Refresh-grant keyed +in-process flights (`src/codex/account-store.ts:288-297`, `:413-439`), a cross-process +file lock with locked re-read (`:448-475`), and generation-CAS persistence (`:521-530`). +The missing piece is an entrypoint that bypasses the freshness shortcut for exactly one +rejected generation. + +### 1. A fenced forced-refresh entrypoint — `src/codex/account-store.ts` + +Takes `accountId`, the rejected credential generation, the rejected access token, and the +caller's abort signal. + +The fence is not a single check at the entrance. Flights are keyed by **refresh-grant +fingerprint**, not by account or generation (`:413`), so a forced caller can join a flight +started by an ordinary refresh, or by another account sharing the grant. The generation +must be re-checked in three places: at entry, in the joined-flight branch before the CAS +write (`:419-439`), and again after the file-lock re-read (`:448-455`). If the stored +generation is no longer the rejected one, someone already replaced the credential — return +what is stored and perform no refresh and no bump. + +`findFreshCredentialForGrant()` (`:375-387`) needs one extra condition. It can return +another alias's still-fresh copy of the **same** access token that just got rejected, which +would bump the generation and replay with the identical bearer — a guaranteed second `401` +dressed up as recovery. The rejected token is therefore an explicit input, and a candidate +equal to it does not satisfy a forced refresh. + +### 2. Dispatch on both endpoints — `core.ts`, `compact.ts` + +Widen the existing `401` branch to `pool` and route it to the new entrypoint. One +request-local replay guard; a second `401` falls through to terminal handling. The replay +reuses the same account — alternate-account selection stays out of the first replay or +fixed-account and pin semantics change. + +Core has a hole compact does not: when the main refresh fails it returns the `401` +response immediately without recording an outcome (`core.ts:3830`), whereas compact records +it (`compact.ts:694`). With no second upstream `401` there is nothing to quarantine on, so +an account whose grant is genuinely dead stays selectable and every request repeats the +same doomed refresh. Core must record a **terminal** refresh failure. + +### 3. Terminal versus retryable refresh failure + +The first draft of this plan asserted `:244-275` already classifies transient refresh +errors. That is wrong: those lines define generation-conflict, lock-timeout, busy, and +stale errors only. A raw network failure or timeout is untyped, and a token-endpoint 5xx +becomes `TokenRefreshError("unknown")` (`:496-506`). Treating "unknown" as terminal +rebuilds this exact bug behind a new door — an upstream blip would quarantine a healthy +account. + +Only `revoked` and `expired` are terminal. Everything else — `unknown`, network +failure, abort, `CodexCredentialRefreshBusyError`, `CodexCredentialRefreshStaleError`, +`CodexCredentialRefreshLockTimeoutError`, `CodexCredentialGenerationConflictError` — is +transient: surface an error to the client, quarantine nothing. + +### 4. Fence the quarantine — `src/codex/routing.ts` + +Add a credential-generation field to `CodexUpstreamOutcomeMeta` and require +`isCodexAccountGenerationLive()` before the `credential` branch quarantines or clears +affinity. This must be a **new** field: the existing `writerGeneration` (`:232`) is the +config-store generation, an unrelated counter. + +The field is optional and absent means historical behavior, so the sidecar recorders that +also report raw pool status (`src/providers/openai-sidecar.ts:133`, `src/server/search.ts:165`, +`src/server/images.ts:514`, `src/server/live.ts:657`) keep working exactly as today. Their +lack of a fence is pre-existing and is recorded as residual below, not silently adopted. + +### 5. Hand the affinity generation forward — `src/codex/routing.ts` + +The first draft claimed affinity survives. It provably does not. An affinity entry stores +the generation it was bound under (`:963-981`) and `isThreadAffinityGenerationLive()` +demands exact equality (`:921-923`). A successful forced refresh CAS-writes generation +`G+1`, so the entry the replay just "preserved" is dead on the very next request, which +deletes it at `:1849-1851`. Not quarantining is not the same as keeping affinity. + +The fix is an explicit same-lineage handoff, and the codebase already has the exact test +for "same lineage": a refresh-owned bump preserves `replacedAt` (`account-store.ts:213`) +while an external replacement stamps a fresh one (`:142`). +`settleCodexQuotaRecoveryProbe()` uses precisely that distinction to accept a `+1` +transition (`routing.ts:564-576`). The affinity handoff advances an entry from `G` to +`G+1` under the same conditions: the account matches, the transition is exactly `+1`, and +`replacedAt` is unchanged. + +## Verification + +Endpoint coverage goes beside the existing main-pool cases in +`tests/responses-native-main-refresh.test.ts:135-161`, whose fixture has no ordinary pool +accounts at all (`:17-31`) — which is why this shipped. + +The assertion is the wrong behavior, not a value comparison. A first ordinary-pool `401` +today produces one upstream send, zero token-endpoint calls, a `401` at the client, +`needsReauth` set, and affinity removed. + +Named mutations, each of which must turn a specific test red: + +1. Restore `authCtx.kind === "main-pool"` on either endpoint → that endpoint's ordinary-pool + case fails with the signature above. +2. Drop the rejected-token condition from the same-grant reuse path → the replay sends the + identical bearer and the test sees two `401`s instead of a `200`. +3. Classify `TokenRefreshError("unknown")` as terminal → the transient-failure case + quarantines a healthy account. +4. Delete the affinity handoff → the **next** request after a successful replay finds a dead + entry and re-selects, which is why the test must issue a second request rather than + asserting on the entry at replay time. +5. Remove the generation fence from the `credential` branch → a stale `401` carrying a + superseded generation quarantines the replacement. + +Store-level concurrency goes near `tests/codex-account-store.test.ts:343-424`: a forced +caller joining an **ordinary** flight for the same grant (not merely two forced callers), +a same-grant alias holding the rejected token, and two concurrent forced refreshes +collapsing to one token call and one generation increment. + +## Residual, carried knowingly + +The sidecar recorders in `openai-sidecar.ts`, `search.ts`, `images.ts`, and `live.ts` +record pool `401`s without a credential-generation fence. That is pre-existing behavior and +unchanged by this work, but a forced refresh makes generation bumps more frequent, so the +window in which a stale sidecar `401` can quarantine a freshly refreshed credential gets +wider. Threading the fence through four more call sites is a separate mechanical change and +does not belong in the same work-phase as the behavioral fix. + +Mid-stream SSE `401`s (`core.ts:1304`, `:4155`) are in scope for the fence but never for +replay: once the stream is committed, a transparent retry would duplicate output the client +has already seen. + + +## Post-implementation review: six defects, all in the fix + +An independent source review of the landed commit returned FAIL and reproduced each +finding with its own probe. Five were in code written for this fix; two of those +existed in `getValidCodexToken` before it and the forced path made them reachable. + +**A joined flight could copy a sibling account's credential.** Flights are keyed by +refresh grant and shared by every account holding it. If the owner's own credential is +externally replaced while it waits for the file lock, the grant-mismatch branch returns +that replacement — and a joiner, checking only its own current grant, would CAS-write +another account's access *and* refresh tokens onto itself. Flight results now carry +`resolvedGrantFingerprint`, tagged with the grant the flight was **opened** for rather +than the rotated one it produced. Tagging the rotated grant instead broke the existing +`same refresh grant joins a live flight` test, which is what caught the distinction. + +**The lineage check was tautological.** Both callers read `replacedAt` after the refresh +and passed it to a function that re-read the same record, so the comparison could not +fail — an external replacement passed it and inherited the rejected credential's +affinity, the exact case the handoff claimed to refuse. Lineage is now proven by the +call that performed the CAS: the store reports `selfRefreshed`, and the handoff only +runs when that is true. The `replacedAt` parameter is gone. + +**A same-bearer refresh neither recovered nor quarantined.** Upstream can rotate only +the refresh grant and return the same access token. The store commits `G+1` regardless, +so quarantining against `G` was silently suppressed by the new fence — the account was +neither replayed nor retired, and the next request repeated the refresh. The refresh +result now reports the generation the credential actually sits at, and both endpoints +fence on that value. + +**An ordinary joiner could bump the generation twice.** With the refresh grant retained, +an ordinary same-account caller joins the forced caller's flight and CAS-writes the +identical credential, moving `G+1` to `G+2` and killing the handoff the owner just +performed.

It is asking upstream to describe what a +prehistoric client may use, and then treating the answer as what this account owns. + +`#2550` added the three slugs to `ACCOUNT_GATED_NATIVE_OPENAI_MODELS` +(`src/codex/catalog/native-models.ts:5-10`), which is correct policy for the inverse +report in `#2548`. Fail-closed is right when entitlement is unknown; the defect is that +the input was never a real entitlement answer. A valid `{models:[...]}` response sets +`confirmed: true` regardless of contents (`:133-143`, `:172-180`), availability requires +`confirmed && models.has(id)` (`:317-327`), and catalog sync then drops the rows +(`src/codex/catalog/sync.ts:1579-1596`). + +The account's plan is never consulted, and WHAM is a separate request +(`src/codex/auth-api.ts:767-785`) — `plan=plus, status=200` proves authentication, not +roster contents. The reporter's evidence and the code were measuring different things. + +## Where the real version comes from + +There is no existing outbound precedent to copy: native forwarding uses +`FORWARD_HEADERS` (`src/adapters/openai-responses.ts:35`), which carries neither +`user-agent` nor any version header, and the other `client_version: "0.0.0"` sites +(`src/codex/convergence.ts:476`, `src/codex/catalog/sync.ts:1988`) are local Codex cache +wrappers, not upstream requests. + +But the best source is already in hand for the path that matters. A live catalog request +arrives **from Codex**, carrying its own `client_version` query parameter, and the handler +already detects it (`src/server/index.ts:1173`) while calling entitlement discovery +without it (`:1073`). The value is right there and is thrown away. + +So version authority is a precedence chain, not a single lookup: + +1. **The inbound request's `client_version`**, when the caller supplied one. This is the + only value that is certainly the version of the client being answered. +2. **The selected Codex runtime version** for background sync, where there is no inbound + request. `loadPersistedCodexRuntime()?.selectedVersion` (`src/codex/runtime.ts:256`) + performs no freshness validation and the file is written only by runtime-selection paths + (`:621`), so it can be absent after a persist failure, stale before selection runs, or + describe the binary OpenCodex chose rather than an externally launched client. Retained + sync does refresh runtime evidence first (`src/codex/catalog/sync.ts:1828`), which is + what makes it usable here and not elsewhere. +3. **Neither available → ask under this build's own gated floor.** + `GATED_MODEL_CLIENT_VERSION_FLOOR` is derived from the highest + `minimal_client_version` that `src/codex/data/upstream-models.json` records for the + models in `ACCOUNT_GATED_NATIVE_OPENAI_MODELS` (`0.142.2` today). It is a claim this + repository can substantiate, and it is derived rather than written down so a refreshed + snapshot cannot leave it stale. + + **This tier was wrong in the first attempt and CI caught it.** The original design said + "neither available → do not ask", on the reasoning that failing closed on absent evidence + was the existing contract. That is true for a *request*, and false for background sync: + `syncCatalogModels` has no inbound request, and on a host where Codex has never been + resolved it has no persisted runtime either — yet it is exactly the path that publishes + account-confirmed native rows. Skipping discovery there suppressed the rows this fix + exists to restore. Two pre-existing tests failed on `dev` CI and neither was in the + originally chosen focused set: + `tests/claude-models-discovery.test.ts` ("Codex discovery exposes the observed native as + a selector row plus one global bare row") and `tests/codex-catalog-sync-hardening.test.ts` + ("account sync preserves an observed gated native only after the mapped account confirms + it"). The lesson is narrow and worth keeping: *fail-closed is a property of a request + path, and a background publisher is not a request path.* + + Sending `0.0.0` remains forbidden, and now by value rather than by exact string — + `0`, `0.0`, `00.0.0`, and `0.0.0-dev` all make the same claim (a client predating every + gated model) and are all rejected. The value is also length-bounded because it is + interpolated into an outbound URL. + +This needs a real seam. `fetcher` (`:43`) can observe the URL but cannot choose the +version, so `resolveCodexModelEntitlements` and `isDirectCallerEntitledToCodexModel` +both take an explicit client version. + +## The cache has to be version-scoped + +`accountModelsCache` is keyed by account ID alone, with credential identity stored as a +discriminator (`:30`, `:216`); the flight key is account plus credential identity +(`:223`). Version must join both, or a roster fetched under one version keeps answering +for another until the TTL expires. + +The first attempt kept the account-only **cache key** and merely compared the stored version +on read. Review showed that is not equivalent: with two versions in flight for one account, +the later-completing one overwrites the earlier, and the *unversioned* projection readers in +`src/codex/catalog/metadata.ts:424,514` then publish whichever landed last rather than what +each client proved. The key itself is now `account\u0000version`, with account-scoped +invalidation walking every version's entry so a credential change still clears all of them. + +`cachedAvailableAccountGatedNativeModels` scans every cache entry (`:331`). Once two +versions can be retained at once, that scan will leak a newer roster into an older +client's projection — the `#2548` failure, arrived at from the opposite direction. It has +to filter by the version being projected. + +`isCodexModelEntitlementSnapshotCurrent` validates credentials only (`:346`); a runtime +version change during a gather needs the same stale-result protection. + +## Sub-defect B, correctly scoped + +`ocx models enable gpt-5.6-sol` fails because `/api/model-visibility` builds +`supportedNative` from `nativeModelRows(config)` +(`src/server/management/model-routes.ts:461-468`), which has already dropped the +suppressed rows, so validation rejects at `:477-478`. + +Validating bare native IDs against the static `NATIVE_OPENAI_MODELS` set +(`src/codex/catalog/native-models.ts:69`) fixes that, **unioned with** the existing +account-qualified targets rather than replacing them. + +Being precise about what this buys: acceptance only clears `disabledModels` (`:532`). +Entitlement still filters `nativeModelRows` (`src/codex/catalog/metadata.ts:424`) and +routing stays gated. So B is **not** a manual escape from a false negative — the earlier +draft of this page claimed that and was wrong. B removes a misleading 400 and lets an +operator pre-clear an independent disable key. If no disable key exists, B changes nothing +the user can see. A is the fix; B is a UX and configuration repair that stops the CLI from +lying about why. + +## Verification + +**A** in `tests/codex-model-entitlements.test.ts` (fetch seam already exercised at +`tests/codex-model-entitlements.test.ts:38`): a mock backend that returns a legacy-only +roster below the threshold and the full roster at `0.146.0`. The wrong behavior asserted +is the real one — *an entitled account is classified as denying GPT-5.6 because OpenCodex +under-reports its own client version*. Named mutation: restore the `0.0.0` literal. + +A second case pins the precedence chain's last tier: with no inbound version and no +persisted runtime, discovery must still ask — under the derived floor, verbatim. Named +mutations: return `null` from tier 3 (three tests fail, including the two CI regressions +above), and hardcode a stale floor instead of deriving it from the snapshot. + +Cache identity gets its own case, and the **first version of it was vacuous** — an +independent review proved the test stayed green after reverting *both* the cache-hit version +comparison and the version component of the flight key. It seeded the cache directly through +`seedCodexModelEntitlementsForTests`, so it only ever exercised the optional projection +filter, never the write path. The rework drives the real path through a Direct caller, whose +credential identity is derived from its own bearer token (`direct:`) and therefore +satisfies the identity guard that decides whether a completed flight may write — which a +synthetic pool credential never does. Two cases now: + +- sequential: fetch under version A, ask again under A (served from cache, no second + request), then ask under B and assert a re-fetch; +- concurrent: two versions in flight for one account, completing newest-first, and both + answers must survive. Named mutation for both: collapse the cache key back to account-only. + The flight key's version component has its own mutation, which the concurrent case catches. + +The version is also asserted end to end at the route: `/v1/models?client_version=0.151.7` +must produce `0.151.7` on the outbound `/codex/models` request. Named mutation: drop the +`url.searchParams.get("client_version")` argument in `src/server/index.ts`. + +Tier 2 is memoized for five seconds because it reads `codex-runtime.json` from disk on every +gated authorization and every `/v1/models` resolution, including when the roster cache is hot +and the answer needs no I/O at all. Named mutation: bypass the memo and re-read every time. + +**B** in `tests/model-visibility-management-api.test.ts`: with `disabledModels: +["gpt-5.6-sol"]` and no entitlement cache, the PUT must be accepted and clear the entry, +specifically not returning `invalid model visibility target`. Named mutation: derive +`supportedNative` from `nativeModelRows` again. + +## What this does not claim + +### The floor is an entitlement probe, not client-compatibility evidence + +An independent review called this a blocker: tier 3 asks under `0.142.2`, which is a *model +requirement*, not evidence of the installed client's version, so an entitled account can have +gated rows published into a catalog that an older externally launched Codex cannot drive — the +#2548 direction. The reasoning is sound and the risk is real. The fix is still the floor, for +four reasons that the code and the existing tests support: + +1. **The suggested alternative contradicts `dev`.** "Refuse or defer the durable catalog write + when no client version is available" is what returning `null` did, and two tests already on + `dev` fail under it: `tests/claude-models-discovery.test.ts` and + `tests/codex-catalog-sync-hardening.test.ts` ("account sync preserves an observed gated native + only after the mapped account confirms it"). Those tests encode the intended behavior — a + background sync *should* confirm entitlement and publish. A change that contradicts them is a + separate, deliberate decision, not a fix to this bug. + +2. **Tier 2 already handles the known-old-client case correctly.** If a Codex runtime has been + resolved and it is older than the gated models require, tier 2 supplies *that* version, upstream + returns no gated rows, and they stay suppressed — which is exactly right. Tier 3 is reached only + when no runtime has ever been resolved, so there is no known client to be wrong about. + +3. **The floor is the narrowest probe that can work.** It is the lowest version under which the + gated models can be returned at all. Asking under it cannot manufacture a confirmation: an + unentitled account still comes back without the rows. + +4. **Client-compatibility filtering has never existed here.** No code path in `src/` consults + `minimal_client_version`; both catalog sites delete it (`catalog/parsing.ts:486`, + `catalog/metadata.ts:502`). The proxy has never enforced client-version compatibility, so this + change does not remove a guard — it leaves a pre-existing gap where it was. + +The tradeoff, stated plainly: the failure this accepts is a model appearing for a client too old to +drive it, which surfaces as an upstream error on use. The failure it fixes is an entitled account on +a current client silently losing GPT-5.6 — the reported bug. Adding a real client-compatibility +filter is worth doing, and it is its own unit of work with its own decision about those two tests. + +The reporter supplied no captured `/codex/models` response, so I cannot prove their +machine took the confirmed-negative branch rather than a transient failure. Both produce +the same symptom. The version-filter explanation is what the source, the version boundary, +and this repository's own measurement support, and the fix is correct either way — but if +their roster was failing for another reason the models will still be missing afterwards, +and the issue should be reopened with a redacted capture rather than assumed fixed. diff --git a/devlog/_plan/260829_bugpr_lane_h_residual_issues/170_pr2895_pool_401_recovery_budget.md b/devlog/_plan/260829_bugpr_lane_h_residual_issues/170_pr2895_pool_401_recovery_budget.md new file mode 100644 index 0000000000..d4e267d9ae --- /dev/null +++ b/devlog/_plan/260829_bugpr_lane_h_residual_issues/170_pr2895_pool_401_recovery_budget.md @@ -0,0 +1,111 @@ +# Lane P — #2895 / #2892 gap 5: one recovery budget for a stored Pool 401 + +Carries contributor PR #2895 (`luvs01`, `a838b071c`) onto current `dev` and corrects the one +blocker in it.

The real owner is +`rotateGenericOAuthAccountOn429` (`src/oauth/generic-account-failover.ts:157`); it keeps +its contract (cooldowns, reauth skipping, request-local rotation, never mutating +`activeAccountId`) and gains a rank step in place of its inline ring walk: + +```ts +// src/oauth/account-quota-rank.ts +export function rankAccountsByHeadroom(provider: string, ring: string[]): string[]; +``` + +### The ring is built first, then ranked + +This ordering is load-bearing and easy to get wrong. `eligibleFailoverAccounts` returns +ids in **stored** order (`:143`), while the existing traversal starts **after the failed +account** (`:184`). Ranking the stored-order list would silently change today's behaviour: +with roster `[A, B, C]` and `B` failing, stored order picks `A` where the ring picks +`C`. + +So the caller constructs the ring explicitly, then ranks it: + +```ts +const order = set.accounts.map(a => a.id); +const start = order.indexOf(failedAccountId); +const ring = start >= 0 ? [...order.slice(start + 1), ...order.slice(0, start)] : order; +const candidates = ring.filter(id => eligible.includes(id) && id !== failedAccountId); +return rankAccountsByHeadroom(providerName, candidates)[0] ?? null; +``` + +Rules, in order: + +1. **Synchronous only.** It reads `getCachedProviderAccountQuota(provider, id)` + (`src/providers/quota.ts:1470`), which never probes the network. Rotation happens + mid-request while a 429 is in hand; it cannot await a usage call. +2. **Three categories, no numeric weight.** Accounts fall into + `known-healthy` → `unknown` → `known-exhausted`, where exhausted is our own verdict + from `010` (limit reached with overage disabled). No borrowed constant: an unknown + account must obviously be tried before one we measured as empty and after one we + measured as full, and that ordering needs no tuning parameter. +3. **Within known-healthy, sort by descending headroom.** Headroom = `100 - percent` of + the monthly window (Kiro's plan window), or the minimum across known windows for + providers reporting several. +4. **Stable within a bucket.** Ties preserve ring order, so the deterministic + walk-the-roster property survives. Deterministic by choice: with a handful of accounts + and a fresh rank per request, randomization buys nothing and costs reproducibility. +5. **Zero quota data anywhere → identity.** Returns the ring unchanged, so behaviour for + every provider without per-account quota is byte-for-byte what it is today. + +## No live decrement (withdrawn after audit round 1) + +An earlier draft proposed nudging the cached percent after each successful turn to close +kiro-lb's 15-minute staleness gap. It is removed: `ProviderQuota` carries no absolute +limit to divide by, and Kiro bills fractional credits, so a per-turn increment would be +fabricated. Stale truth beats invented precision. + +Be precise about the freshness we do claim, because there are **two** different TTLs: + +- **Provider-level display** rows cache for 5 minutes (`src/providers/quota.ts:37`). +- **Per-account** rows — which are what this ranking reads — cache for **10 minutes** + (`:1425`), deliberately longer because the cost multiplies by account count. + +So recovery ranking can act on data up to 10 minutes old. That is still better than +kiro-lb's 15-minute default poll, but the honest margin is 10-vs-15, not 5-vs-15. + +## Exhaustion cooldown + +When `010`'s snapshot says `exhausted`, seed the failover cooldown for that account until +`nextResetAt` (clamped: minimum 5 minutes, maximum 24 hours) instead of the default 60s. +Retrying a monthly-exhausted account every minute is pure waste. The clamp keeps a bogus +upstream reset date from parking an account for a month — kiro-lb allows a 32-day +quarantine, which we consider too much rope. + +The exhaustion state is owned by the generation-guarded store described in `070`, not by +an ad-hoc module map; a stale `exhausted` flag surviving an account removal would hand a +replacement account a 24-hour cooldown it never earned. + +## Accept criteria + +| # | Scenario | Observable proof | +| --- | --- | --- | +| 1 | A at 10% used, B at 90% used | A ranks first | +| 2 | A unknown, B at 95% used but NOT exhausted | B ranks first — B is known-healthy, and the categorical rule has no "known-low" tier | +| 3 | A unknown, B at 5% used | B ranks first (known-high beats unknown) | +| 3b | A unknown, B exhausted (limit reached, overage off) | A ranks first (unknown beats known-exhausted) | +| 4 | No quota data for any account | order identical to input (activation: proves the no-op path) | +| 5 | Equal headroom | ring order preserved | +| 6 | Rank called during rotation | zero network calls (assert fetch not invoked) | +| 7 | Exhausted + `nextResetAt` in 3 days | cooldown clamped to 24h, not 3 days | +| 8 | Exhausted + `nextResetAt` in 30 seconds | cooldown floored at 5 minutes | +| 9 | Roster [A,B,C], B fails, no quota data | C selected (ring), not A (stored order) | +| 10 | Rotation still skips cooled/reauth accounts | existing failover tests stay green | + +## Blast radius + +`rankAccountsByHeadroom` runs for every generic-failover provider, so criterion 4 is the +one that protects xAI, Cursor, Copilot, Kimi and Antigravity from behaviour change. +`tests/generic-oauth-failover.test.ts` and `tests/adapter-event-oauth-failover.test.ts` +must stay green untouched. + +## Verifier + +`bun test tests/kiro-pool-rank.test.ts tests/generic-oauth-failover.test.ts tests/adapter-event-oauth-failover.test.ts` diff --git a/devlog/_plan/260829_kiro_quota_pool/040_surfaces_cli_gui_docs.md b/devlog/_plan/260829_kiro_quota_pool/040_surfaces_cli_gui_docs.md new file mode 100644 index 0000000000..ef374a62ca --- /dev/null +++ b/devlog/_plan/260829_kiro_quota_pool/040_surfaces_cli_gui_docs.md @@ -0,0 +1,74 @@ +# 040 — Phase 4: surfaces (CLI, GUI, docs) + +Work class: C2.

Corrected in round 2.) + +## Blocker 4 — the Anthropic fail-closed rule breaks Kiro probes. FOLDED. + +Sharp catch. `getTokenForAccountQuotaProbe` refuses to refresh a background +`source: "local-cli"` account (`:1549`) because Anthropic's lock can adopt a mismatched +Claude CLI identity. But Kiro's *imported* credentials are marked `local-cli` +(`src/oauth/kiro.ts:301`) for an unrelated reason — they came from the Kiro CLI database. +Reusing that rule verbatim would make every inactive Kiro account's quota go unavailable +the moment its token expired, which is precisely when a pool needs it. + +**Amendment to `020`:** the fail-closed branch stays Anthropic-scoped.

Pure move, no behaviour change; `quota.ts` +re-exports nothing new publicly. This is a prerequisite step inside phase 1, and the +existing `tests/provider-quota.test.ts` is the regression proof that the move is inert. + +## Blocker 7 — only the ARN region was validated.

Both are single added lines in + functions that already do this for quota; no new registration in + `src/lib/state-store-registrations.ts` is required because the owner is already + registered there (`reconcileProviderAccountQuotaRows`). +4. **Consumed** by `030`'s cooldown seeder through one exported reader, + `getKiroAccountExhaustion(provider, accountId)`. Generic failover imports that reader; + it does not reach into the map. + +### Freshness (added in round 3) + +Storing `ts` without a staleness rule would let an old `exhausted` verdict keep an +account last-ranked, or re-seed a 24-hour cooldown, long after its quota actually reset. +`getKiroAccountExhaustion` therefore returns **unknown** — not `exhausted` — when +either holds: + +- `now - entry.ts >= ACCOUNT_QUOTA_TTL_MS` (the existing per-account TTL, which is + **10 minutes** at `src/providers/quota.ts:1425`, not 5 — the 5-minute figure is the + provider-level cache at `:37`).

An independent recon audit re-derived both remaining gaps from current +`dev` and confirmed each is still reachable — and corrected the reporter on one +point, recorded below. + +## Gap 3 — a rotated grant never reaches an inactive same-grant alias + +A successful refresh persists the rotated credential to the flight owner only, via +the generation CAS at `src/codex/account-store.ts:748`. A live joiner can CAS the +result onto its own record. Nothing writes to a third category: a non-deleted +record carrying the same `refreshGrantFingerprint` that is not participating in +the flight. + +`findFreshCredentialForGrant` (`src/codex/account-store.ts:393`) is a pre-fetch +lookup and propagates nothing. So the alias keeps a refresh token that upstream +has just rotated away. The next refresh on that alias sends a dead grant, and +`invalid_grant` is classified `revoked` — which retires a healthy account. That +classification is correct behavior for a genuinely dead grant; the defect is that +the grant died because we rotated it and never told the alias. + +### The design an adversarial audit rejected + +My first plan had two branches: an untouched alias adopts the rotated credential +whole, and an alias whose access token had changed concurrently keeps its own +access token but takes **only** the rotated refresh token. An independent audit +refused that second branch, with two findings I could not rebut: + +- The generation fence in `src/codex/plan-from-token.ts:32` treats a higher + generation as proof of a **newer access-token JWT**, which is what lets JWT plan + claims supersede an older WHAM observation. Bumping a generation while + deliberately keeping the old access token lets a stale JWT overwrite an + authoritative plan. `tests/codex-plan.test.ts:129` already pins that meaning. +- A flight is keyed by grant and does not record participant account ids + (`src/codex/account-store.ts:308`), so a scan cannot distinguish a dormant alias + from a live joiner. Rotating a joiner's grant while preserving its 401-rejected + access token makes the provenance CAS inapplicable, and the recursion's + freshness shortcut then returns the rejected bearer — defeating 401 recovery in + exactly the case the branch existed to serve. + +### What ships instead + +One batch compare-and-swap, one `persist`, and a deliberately narrow eligibility +test. An alias is repaired only when it is provably an untouched duplicate of the +pre-refresh credential: same old grant fingerprint, same access token, same +expiry, and the same `chatgptAccountId` as the owner. Such an alias receives the +rotated access token, refresh token, and expiry **together**, so the generation +bump keeps meaning what every fence already assumes. `replacedAt` and the +validation metadata are preserved, because the probe-lease lineage check accepts +only an intact `G → G+1`. + +Anything else is left alone: a differing access token, a differing account id, or +a tombstone. The `chatgptAccountId` equality requirement is not decoration — a +fingerprint is `sha256` of the refresh token and carries no identity claim +(`src/codex/account-store.ts:62`), and no repository invariant guarantees one +grant cannot span two account ids. + +This is a **partial** close of gap 3, and the issue comment says so. Dormant +duplicates stop being retired for a grant we rotated away; a mixed alias still is. +Healing that case needs durable grant lineage and verified identity binding, which +the current fingerprint-and-generation model cannot express safely. + +The flight's returned `resolvedGrantFingerprint` stays the **old** fingerprint: +joiners wait on that key, and retagging it would make every legitimate joiner look +foreign. + +## Gap 4 — stale credential evidence writes unscoped state + +The reporter described an async interleaving between validation and mutation. That +part is wrong and worth stating: `recordCodexUpstreamOutcome` is synchronous +(`src/codex/routing.ts:2095`) and there is **no `await`** between the generation +check at `src/codex/routing.ts:2210` and the mutations at 2216–2223. The +same-process race the issue describes is not reachable. + +The cross-process race is real regardless. The check is an unlocked synchronous +store read (`src/codex/account-store.ts:186`) while writers coordinate under the +mutation lock, and OS preemption needs no `await`. The side effects then carry no +credential identity: health entries have no generation field, reauth state is a +bare `Set` fenced only by config generation, and affinity clearing removes +every entry for the account. + +Affinity is already self-invalidating on the next generation check. Health and +reauth were not. + +My first attempt snapshotted the state, mutated, then re-read the generation and +rolled back. Two reviewers independently rejected it, correctly: a replacement can +land at any point *after* `recordCodexUpstreamOutcome` returns, so a post-write +read narrows the window without closing it. @Ingwannu reproduced the surviving +ordering on the exact head — record a 401 at G, return, then persist G+1, and the +quarantine still applied to G+1. + +The evidence is now tagged with the credential it came from and checked when it is +*read*, which is what actually settles it. `credentialFailureGeneration` holds the +generation a 401/403 was derived from, and the health readers (`shouldFailover`, +`getCodexUpstreamHealth`) drop a failure whose credential is gone. The reauth set +became a map from account id to the generation that justified the flag, with +`undefined` preserved as an account-wide mark so a login flow with no specific +credential still quarantines unconditionally. + +Affinity clearing stays un-reverted: entries already carry a generation and +self-invalidate, so re-adding swept entries would be the worse bug. +`recordCodexUpstreamOutcome` stays synchronous — many callers consume it as +`void` (`src/server/responses/core.ts:391`), so making it async would silently +leave mutations unawaited. The config lock is still never taken on the request +path; it runs with `busy_timeout=0`, and per-outcome acquisition would turn +contention into request errors. + +## The alias plan note + +Review also caught that propagation installs the rotated JWT on an alias but left +its configured plan alone: a `plus → pro` rotation gave the alias a Pro credential +while its plan stayed `plus`, and the cached-token fast path never repairs that, so +quota scoring and the 30-day projection stayed wrong until a restart or a WHAM +refresh. Each propagated alias is now reconciled at its **own** committed +generation, which is why the commit returns `{ id, generation }` rather than ids — +aliases need not share a generation, and the plan note is generation-fenced. + +That last point produced the one genuinely vacuous assertion of this unit: with a +single `saveCodexAccountCredential` per record, owner and alias generations +coincided, so an assertion about the per-alias fence passed even when the code used +the owner's generation. The fixture now advances the alias twice so the generations +diverge, and the mutation turns red. + +## Constraints the audit flagged + +The refresh-flight map is keyed by the old grant (`src/codex/account-store.ts:315`) +and joiner provenance deliberately carries that old fingerprint, so alias +propagation must not disturb that ordering. The config lock runs with +`busy_timeout=0` and must stay synchronous, so the routing path must not acquire +it per outcome. Affinity requires exact credential-generation equality, so any +alias generation bump has to be reasoned about rather than assumed harmless. + +## Evidence standard + +Each regression is driven red by a named mutation, using the existing blocked-fetch +seam rather than a timing sleep.

My unit reduced to the tests and the explanatory comment. + +## Fix + +Read the nested boolean, positioned after the explicit-modality and architecture signals, with precedence **by specificity**: a flat `capabilities.vision` boolean is authoritative whenever present, the nested `supports.vision` boolean is consulted only otherwise, and a non-boolean at either level decides nothing so the remaining signals still apply. + +**The read is not scoped to `github-copilot`, and that is deliberate rather than overlooked.** `modelInputModalities` never receives a provider name, and the nested field is the same kind of evidence wherever it appears — a boolean statement about one model. Scoping it would mean a provider reporting the identical shape gets a worse answer for no reason. What the choice does mean is that any provider emitting `capabilities.supports.vision` as a boolean now has it honoured, so the nested field must behave **exactly** like the flat field it stands in for. That equivalence is pinned by a test comparing both shapes against the same loose capability-array claim. + +Strictness matters in both directions. A truthy test would let the string `"yes"` advertise image support, and coercing a non-record `supports` into a denial would suppress a `features: ["vision"]` signal that is still valid. + +## The precedence mistake, recorded because it nearly shipped + +I first wrote the denial as `flat === false || nested === false` — deny-wins across both sources. It reads as the safe direction and is not. + +On a provider reporting flat `vision: true` with nested `supports: { vision: false }`, deny-wins returns `["text"]` where the old code returned `["text", "image"]`. That is a silent behaviour change in a parser shared by **every** provider, shipped by a patch whose entire purpose was to stop models being wrongly marked text-only. Eleven of twelve capability shapes agree between the two resolutions; that one does not, and it is the one that would have caused a regression. + +A differential probe over both resolutions is what surfaced it — not review, and not green tests, since neither suite covered a disagreeing pair. The case is now pinned: reintroducing deny-wins turns `a flat vision boolean outranks a disagreeing nested one` red. + +## Rejected: a registry seed + +The issue offers "just add `modelInputModalities` to the `github-copilot` registry entry" as the easier route. + +An audit pushed back on my first reason for rejecting it, correctly. `modelInputModalities` is a **per-model** map, not a provider-wide boolean, and other providers do seed selectively — xAI lists specific verified vision ids. So "Copilot serves both vision and text-only models" does not by itself rule out a seed, and a selective one would even help during first start or degraded `/models` discovery, since the registry model list is explicitly a cold-start fallback. + +The real reason to omit it here is narrower: **a seed is only as good as the audited list behind it, and no verified model-by-model Copilot vision list exists.** Writing one from the 32 models named in the issue would be guesswork duplicating a remote catalog that changes without us. A selective seed remains a legitimate follow-up for whoever can audit the list. + +One qualifier on "parse what upstream reports": it is the best per-model evidence available, not an oracle. When two upstream forms disagree the output can still be internally contradictory — a model can end up with `inputModalities: ["text"]` next to `capabilities: ["vision"]`.

Because it sits inside `.row models-provider-toggle` +(`Models.tsx:1226`) and `.row` is `display: flex` (`styles.css:1205`), the chip +is a **flex item**: its `inline-block` outer display is blockified and its +initial `flex-shrink: 1` applies. Measured computed values confirm it — +`white-space: normal`, `flex-shrink: 1`. + +`inline-block` does not imply `white-space: nowrap`. The chip's only floor is +`min-width: auto`, which resolves to the text's **min-content** width — and for +Korean that is nearly one syllable, because CJK line-breaking permits a break +between Hangul syllable blocks.

An +audit also found a chip-level floor unsafe across the eight other `.models-chip` +call sites. The shipped fix leaves the shared `.models-chip` primitive untouched; +it adds an ellipsis only to the toggle-scoped descendant — see `010` and `011`. + +## Defect 2 — the name overflows a zero-width box instead of reflowing + +The name span carries inline `whiteSpace: "nowrap"` (`Models.tsx:1232`) while +`styles-models-workspace.css:267` gives it `min-width: 0` and +`overflow-wrap: anywhere`. Those two fight: `nowrap` suppresses the wrapping +that `overflow-wrap: anywhere` was added to provide, `min-width: 0` lets the box +shrink to nothing, and the default `overflow: visible` means the glyphs keep +painting outside the box — straight across the sibling count. + +Nothing positions these elements on top of each other: there is no `position`, +transform, or negative margin anywhere in the applicable rules. The count is +laid out normally *after* a box that measures 0px, so the collision is pure +overflow. + +Why the header's own `flex-wrap: wrap` does not save it: the header's direct +children are only the toggle button and the actions container. Wrapping does not +propagate into descendants, and the toggle's inner `.row` has no `flex-wrap`, +so the chevron, name, chips and count are locked on one line and shrink against +each other. + +The upstream enabler is `flex: 1` on the toggle (`Models.tsx:1229`), which +resolves to `flex: 1 1 0%` — zero basis, shrink allowed — combined with +`min-width: 0`.

Measured: the candidate +left the name box at 0.0px, byte-identical to baseline. The shipped fix gives the +toggle a real flex **basis** so its content enters the header's wrap decision, and +removes every child's min-content floor so the row can always shrink back inside the +card — see `010`. + +## Defect 3 — three controls carry no visible meaning (two switches and the `+`) + +`Switch` (`ui.tsx:8`) accepts a `label` prop and spends it **only** on +`aria-label` (`ui.tsx:11`); its sole child is ``.

Each row was +driven by actually removing the declaration and re-measuring. Contrast drafts 1 and 3, +where four of five and two of three declarations measured inert. + +## Cost of the universal rule + +`white-space: nowrap` on every child means no child of this header can wrap. That is +correct here — it is a single-line identity row of a slug, chips and a count, none of +which should ever wrap — but it is a real constraint on future content. Anything +genuinely multi-line belongs in `.models-provider-body`, not the header. The +alternative was another enumerated exception list, which is what drafts 2-4 already +disproved. + +## What is deliberately NOT changed + +- **The shared `.models-chip` rule.** Only the toggle's own children are touched. The + model-row chips at `Models.tsx:1447-1455` sit in a non-wrapping `.row` with long + translations (de "Benutzerdefiniert", ru "Пользовательская"); a primitive-level + change there was rejected in draft 1. +- `overflow-wrap: anywhere` stays on the existing name rule although the inline + `white-space: nowrap` makes it dead. Removing it is unrelated cleanup; it is noted + so the next reader knows it is inert rather than load-bearing. + +## Diff scope + +- `gui/src/pages/Models.tsx` — one inline style value. +- `gui/src/styles-models-workspace.css` — two rules added (the universal child rule + and the `svg` exemption); the existing `min-width: 0` on the toggle is kept. +- `gui/tests/models-provider-head.test.ts` — extended; the existing line-29 + `min-width: 0` assertion stays valid and must not be removed. +- `gui/tests/helpers/css-declarations.ts` — NEW. The shared source-text CSS readers, + lifted out of `viewport-scroll-caps.test.ts` so two tests can use one copy. +- `gui/tests/viewport-scroll-caps.test.ts` — its four file-local helpers are deleted and + replaced by an import from that module; its assertions are unchanged. + +## Regression test (red first) + +Use the effective-declaration reader so a commented-out or custom-property occurrence +cannot satisfy an assertion. + +**It lives in `gui/tests/helpers/css-declarations.ts`**, which exports +`effectiveDeclaration`, `ruleBodies`, `allRuleBodies` and `withoutComments`. + +That module is part of this change. The reader originated in +`viewport-scroll-caps.test.ts` (PR #2915) as four **file-local, unexported** functions, +so it could not be imported as first planned. B resolved that by moving all four into the +shared module and rewriting the original test to import them — one copy, not the third +copy that copying them here would have produced. + +**What this gate can and cannot see.** The reader's own comment (:53) records that it +does not model competing specificity, `!important`, or at-rule nesting. So it proves +the four declarations exist on the exact selector, and nothing about computed layout: +the ellipsis, the containment numbers, and the 14px chevron are **measurements** +recorded above, not unit assertions. That split is deliberate and is why the tables in +this document are the primary evidence for the fix. + +1. The provider-toggle button in `Models.tsx` carries `flex: "1 1 auto"`. The + negative half must be **scoped to that style object**, not a file-wide search for + `flex: 1` — a legitimate bare `flex: 1` exists at `Models.tsx:2162`, so a global + assertion would be wrong. This is the declaration whose absence reproduces the + user's screenshot. +2. `.models-provider-toggle > *` declares `min-width: 0`, `overflow: hidden`, + `text-overflow: ellipsis` and `white-space: nowrap`, with a comment naming the + defect so the rule is not narrowed back to specific children later. +3. `.models-provider-toggle > svg` declares `flex: none`. Assert this **separately** + from rule 2: it is the declaration whose removal reintroduces the 2.5px chevron, and + a reader who sees only the universal rule is likely to delete it as redundant. +4. Every direct child the toggle renders is an **element**, never a bare string. The + universal selector cannot reach an anonymous flex item, so this is the invariant the + `> *` bound actually rests on. Assert that the JSX between the toggle's opening and + closing tag contains no bare interpolation — all seven children today are `` or + ``. + +A declaration test cannot observe clipping, so the containment table above stays a +recorded measurement rather than a unit assertion. + +## Render grounding + +Screenshots at the failing width, captured from the running dashboard and then **read +back** rather than merely produced: `evidence/010-before-ko-1100.png` and +`evidence/010-after-ko-1100.png` (ko, 1100px, dpr 2, the second chip-bearing provider +row).
