feat(spend): make the durable token ceiling configurable and its refusal legible - #5032
Conversation
…sal legible (#4546) The spend-reservation ledger has reserved, journalled and refused since it landed, and no configuration could set a limit: every scope limit was undefined, the process-wide ledger was constructed with no policy argument, and src/types/config.ts declared no spend key. limitFor() therefore answered undefined on every install and the refusal branch was unreachable in production. Adds a strictly validated spend section with per-scope token ceilings, configureSharedSpendLedger to apply it at startup and to reconfigure a ledger that already exists, an admission gate that refuses an already-spent root before the body is parsed, and a refusal that names the scope and the ceiling on the message, the header, the synthetic log row and the workflow event. Unconfigured installs are unchanged: an absent, empty or ceiling-less section resolves to the observe-only default, resolves no ledger and opens no journal.

When a ceiling applies and the journal is corrupt or an append fails (for example, disk-full or permission errors), reserve() returns journal-corrupt or reserve-not-durable, but this branch returns true, so the physical send proceeds without any reservation and repeated sends can bypass every configured ceiling. Observe-only accounting may degrade open, but once an operator configures a ceiling these denials must stop dispatch rather than silently disable the protection.

For a normal top-level request carrying thread-id or session-id but no x-codex-parent-thread-id, this assigns no root and admitWorkflowTurn immediately returns undefined; attachRequestSpendTracker likewise omits rootId. Consequently spend.root.maxTokens neither accounts nor refuses ordinary top-level tasks and only protects requests that happen to carry the parent header. Derive the root from the top-level conversation identity when the parent header is absent, and use that same derivation in admission, send accounting, and the spend tracker.

The production tracker keys these scopes from logCtx.accountLogLabel and logCtx.provider, but those are presentation fields rather than the declared identities: Codex formats the provider as an account-specific value such as chatgpt-pabc123, while Anthropic deliberately omits accountLogLabel and folds the account into an anthropic-p… provider label. Thus Codex/Anthropic pool spend is split per account, and Anthropic's identity ceiling is not applied at all, allowing account rotation to exceed the configured pool and identity limits. Carry stable account and canonical provider-pool identifiers separately into the tracker.

Reserve the effective omitted-output ceiling before dispatch. src/server/responses/request-prepare.ts:379-384 sets spendOutputCeilingTokens only when the caller supplies max_output_tokens. When it is omitted, src/server/responses/request-spend.ts:74-86 passes outputCeilingTokens: 0 to the reservation.
The reservation therefore includes only input tokens. The ledger checks settled + reserved + unresolved + this reservation against each configured limit, so concurrent sends can pass while their output is unreserved. settle() later adds the actual output usage, and the scope can finish above its configured ceiling. This path is reachable through src/server/responses/core.ts:61, which attaches the tracker before the execution budget calls charge() at src/lib/request-execution-budget.ts:261-269.
Populate spendOutputCeilingTokens in request-prepare.ts from the final routed provider/model when the caller omits the field. Use the effective provider or model cap, including the adapter’s omitted-output default, and recompute it after any fallback changes route. Keep the explicit caller value when present. Add focused coverage for concurrent omitted-limit requests crossing a configured scope ceiling.

…4546) The canonical passthrough ladder reports its physical sends after the fetch, through budget.used, which charges the observer post hoc. reserve() refused anything over the limit and a refused reservation books nothing, so the send that would cross a ceiling was dropped from the total. That is a fixpoint: the total stays one send short of the limit forever, the scope never reads as exhausted, and nothing is ever refused. A reservation for a send that has already left now skips the limit check and the durability refusal, and is marked dispatched immediately. Taking the scope over its ceiling is what arms the next refusal. The request execution budget already documented this as the intended behaviour; the ledger could not honour it. A reservation that cannot be made durable now also refuses the dispatch. The ledger raises that denial only under a configured limit, so an unconfigured install is unchanged, and durability before admission is the reason this store is on disk.

Do not accept a denied pre-dispatch reservation.
tracking-capacity-exhausted can be returned by SpendReservationLedger.reserve() without creating a ledger reservation. The branch at src/server/responses/request-spend.ts:103-108 still returns true, and live is updated only after a successful reservation. RequestExecutionBudget.reserveDispatch() therefore accepts the dispatch and creates a permit without a tracker slot. If that permit is released, refund() pops an earlier slot. If the request settles, settle() applies the later send's usage to that earlier slot.
The same state loss exists for a duplicate denial if that denial is reached. A fresh randomUUID() makes that case uncommon in the production tracker, but capacity exhaustion is a reachable case. Configured durability and journal-corruption denials already return false before dispatch. Observe-only journal failures are admitted as successful reservations and do append to live.
Return false for all pre-dispatch denials, including capacity and duplicate denials. If an alreadySent report must remain permissive, append an explicit untracked marker and make refund() and settle() consume that marker without calling ledger operations for another send.

Merging. This closes the last live half of #4546, and I want two things on the record before it lands. The deviation from the brief was correct. I asked for admission at Naming the two limitations rather than papering over them is what makes this mergeable. A send that crosses a ceiling mid-request still reports The unconfigured path staying byte-identical is the property I care most about here, because the ledger is already on and journaling — a default ceiling would have started refusing real traffic on upgrade. Absent, empty and all-scopes-absent resolving to the same observe-only policy, with no ledger resolved at admission and no journal opened, is exactly right. Also noting that the warn-on-load was dropped because |

Summary
An operator can now set a durable token ceiling, a send that crosses one is recorded rather than dropped, and a refusal says which ceiling fired.
The spend-reservation ledger has reserved, journalled and refused since #4546, and #4707 gave it a production caller that books one entry per physical send. What was missing was any way to say yes.
DEFAULT_SPEND_RESERVATION_POLICYleft every scope limit undefined, the process-wide ledger was constructed with nopolicyargument, andsrc/types/config.tsdeclared no spend key — solimitFor()answeredundefinedfor every scope on every install and the refusal branch was unreachable in production. The onlySpendReservationPolicyin the tree with a realmaxTokenslived in two test files.That is why the reported incident passes every live ceiling: the live ceilings are counts (256 physical sends and 64 distinct children per ten-minute window) against a measured rate of about 61 per ten minutes, while ~8.7M uncached input tokens per ten minutes met no ceiling at all.
What this adds
spendsection with per-scope token ceilings (root,identity,pool) andretentionDays, strictly validated at every level.maxTokensmust be a positive integer — 0 would read as a budget and refuse everything.spendPolicyFromConfigandconfigureSharedSpendLedgerinsrc/lib/spend-reservation-ledger.ts, applied at startup beside the other process-wide budgets. Applying a policy to a ledger that already exists reconfigures it rather than rebuilding it, so every figure already accounted survives and raising a ceiling is not a forgiveness.x-opencodex-local-refusalheader, the synthetic request-log row and the/api/workflow-budgetevent ring.The defect that would have made all of that inert, found in review of the first cut. The canonical passthrough ladder does not reserve its physical sends: it sends, then reports the count through
onSendsConsumed, which assigns throughbudget.usedand charges the observer after the fact.src/lib/request-execution-budget.tsalready documented the intended semantics — "the ledger records them even past a ceiling it would have refused, because refusing after the fact only hides spend that was really incurred" — and the ledger could not honour it, becausereserve()refused anything over the limit and a refused reservation books nothing.That is a fixpoint rather than a rounding error. The send that would cross the ceiling is dropped from the total, the total stays one send short of the limit forever, the scope never reads as exhausted, and every later request is admitted. Against a 20M root ceiling with ~142k-token requests, accounting would stall near 19.9M and nothing would ever be refused. A reservation for a send that has already left now skips the limit check and the durability refusal, and is marked dispatched immediately so it cannot be handed back for free. Taking the scope over its ceiling is exactly what arms the next refusal.
The same review found the other half: the production tracker treated every non-limit denial as permission to send, including
reserve-not-durable. Durability before admission is the reason this store is on disk — a send whose record a restart would forget is how an exhausted budget comes back with a fresh allowance — so that denial now refuses the dispatch. The ledger raises it only when a limit is configured, so an unconfigured install is still never refused there. Capacity and duplicate-send-id stay permissive: they say the ledger cannot account for a send, which is a degradation to report, not an outage to cause.Unconfigured behaviour does not change. An absent, empty, or ceiling-less section resolves to the same observe-only policy the ledger has always had: no ledger is resolved at admission, no journal is opened, and nothing is refused. The ledger is on and journalling by default, so a shipped default ceiling would start refusing real traffic on the first upgrade that ran this code — there is deliberately no default figure anywhere in this change.
Reservation-at-admission, and why it is not literally at
src/server/index.ts. AWorkflowSpendRequestneeds an input token count and an enforceable output ceiling. At HTTP admission the body has not been read, no route has been resolved and no account has been picked, so reserving there would book a journal record and consume a send id for a figure known to be wrong. What admission can do without a token count is refuse a scope that is already spent, and that is what it now does — the cheapest refusal in the path. The reservation itself stays at the physical send where the figures exist; identity and pool can only refuse there, because neither is known until routing picks an account.Counts and tokens are an intersection, stated rather than emergent. Counts are checked first because a count check reads two integers this process already holds while a token check may build the ledger and replay its journal. A count denial is decided before any reservation is booked and a token denial before any count is charged, so neither leaves the other to unwind, and neither is relabelled as the other — "sends exhausted" and "spend exhausted" send an operator to two different remedies. Both directions are pinned by new tests.
Validation follows the closed-vocabulary precedent. The root config schema is
.passthrough(), so the section is.strict()likecodexPoolandquotaResetNotify. The #2106 lesson applies with more force here: elsewhere an ignored typo leaves a feature off, here it leaves the budget off, and a budget nobody enforces looks exactly like one nobody has exceeded. A malformed section degrades to no ceiling rather than costing the operator their providers, so the write path rejects it (validateConfigCandidate) and load diagnostics report it (malformedSpendWarning).What this does not reach. The root scope is the
x-codex-parent-thread-idheader, as it already is for the count caps, so unparented traffic sits outside the root ceiling — the identity and pool ceilings still apply to it, and an operator who wants a bound on one-off traffic should set one of those. A send that crosses a ceiling mid-request is still reported on the wire asrequest_send_budget_exhausted, because the request execution budget reduces every refusal toallowed: falsebefore four different dispatch renderers; its log row and event are markedworkflow_spend_exhaustedwith the scope and the ceiling, and the next request is refused legibly. AndlogCtx.spendOutputCeilingTokensis set only from an explicitmax_output_tokensand is not clamped to the model cap, so a caller that sends none under-reserves the in-flight guard — settlement uses real reported usage, so the durable total is unaffected. All three are recorded in the devlog entry rather than fixed here.Finding 2 of the closure assessment — cohort keying concentrating a fan-out onto the interactive account — is deliberately untouched. Nothing here changes routing.
Closes #4546
Verification
Local verification was not run, because this lane forbids it. No test, focused or full, no
bun run typecheck, no build, no install, and noocxinvocation was executed against this checkout — a past local run deleted a real~/.opencodexdirectory. Hosted CI at the exact head is the evidence for this PR.What was done instead:

On the third box specifically: the refusal carries the scope name and the ceiling, never a scope id. Root ids are client thread headers and identity ids are credentials, and the ledger writes salted aliases for exactly that reason — a 429 body is no safer a place for one. A test asserts the raw root id is absent from the body. The one new fail-open surface was closed rather than opened: an undurable reservation under a configured ceiling now refuses. No auth, credential or workflow surface is touched, and the new default remains "refuse nothing".
