From 241406c10b232e8a4fe426ca92b7eb0bb1e16740 Mon Sep 17 00:00:00 2001 From: Franklin Moormann Date: Thu, 6 Aug 2026 14:09:30 -0400 Subject: [PATCH 01/13] feat(graph): carry process lessons across projects Every graph in this system is keyed on the project a file belongs to. That is right for a claim about that file and wrong for a claim about the tools, and the cost was measured across five repositories in one session: token-optimizer-mcp 2800 nodes 35 live lessons mcp-console-automation 83 nodes 0 AiDotNet-Prototype 9 nodes 0 HarmonicEngine 2 nodes 0 ~/.token-optimizer/wiki 15 nodes 0 Structural capture worked everywhere -- 31, 30 and 12 capture events in the three fresh checkouts -- and every lesson sat in ONE project's graph. "Run npm test, not npx jest" and "capture the exit code before piping" were therefore available to be re-learned from scratch in every other checkout on the machine, which is the opposite of what a memory is for. WHAT CROSSES IS NOT A NEW TAXONOMY. SHAREABLE_TYPES is the exact complement of the set staleness.mjs already calls CONTENT_DEPENDENT. A `finding` or `map` is a claim ABOUT its anchor's contents, so carrying it elsewhere would assert something about files that repository does not have. `command`, `failure`, `decision` and `feedback` are claims about the WORK, and the work follows the person. Deriving one set from the other stops them drifting: if a type ever becomes content-dependent it stops being shareable in the same commit. Design points that are load-bearing rather than incidental: * ANCHORED TO ITS ORIGIN PROJECT, not to the file that happened to be open -- that path means nothing in another checkout, and an unanchored finding is refused everywhere else here for good reason. The origin root is a real path, is never content-checked (these types are not content-dependent), and doubles as the provenance a reader needs to judge whether the lesson transfers. * TRIGGER-MATCHED, not anchor-matched. A shared lesson has no meaningful anchor here by construction, so retrieval is the command text through the same appliesToCommand the local path uses. * SECOND, ALWAYS, and capped at 2 within a 160-token budget. Local findings are selected first and keep the full budget; a lesson from another codebase is a weaker signal and must never crowd out this project's own. * NOT READ BACK to the project that taught it -- the local path already serves it, and repeating it under a "from elsewhere" heading would double the tokens and misstate its origin. * NAMED, NOT HEDGED. Wording was measured on this project: findings rendered with "treat this as unverified" scored 1/3 against 2/3 for the identical findings rendered clean. The origin is stated as a fact; the reader judges. * Best-effort. The project write happens first and is never conditional on the shared one; an unreadable shared store costs the caller nothing. WIRED INTO THE ROUTER, not just implemented. This project has twice shipped a feature that was complete, unit-tested and called by nothing -- forTouch and the semantic harvest were both dead on arrival with green suites. So the load-bearing tests spawn pretooluse-router.mjs and read its stdout. Mutation-checked in both directions: remove the router call -> 3 of 8 fail (delivery tests are real) let `finding` cross -> the isolation test fails (the guard is real) The negative tests keep passing under both, so they cannot be satisfied by a feature that simply does nothing. Full suite: 152 suites, 1866 passed, 0 failed. Generated artifacts in sync.

NO inject EVENT. The tier delivered text and spent tokens that nothing recorded, so the balance sheet reported a cost lower than the one actually paid. An overstated saving is the one number this project must never produce, and this produced one silently. Now recorded under its own `surface: 'shared'`: the file surface joins to later read events and a shared lesson has no anchor here to join to, while folding it into `command` would hide how much of the spend is cross-project -- which is exactly the quantity that needs weighing. DELIVERED INTO THE HOLDOUT ARM. A command assigned to the control arm by forCommand still received shared lessons, so the control was not a control: it got knowledge, just from another tier, and every treated-vs-control difference would have understated what injection does. Now drawn on the SAME key as forCommand -- one arm per command, because letting the tiers draw separately puts a command in local-treated and shared-holdout at once and contaminates both. Also fixed on the way: `sessionId` was referenced by the new record() call but missing from the destructured parameters. That is a ReferenceError inside the function's own try/catch, so the tier would have failed silently rather than loudly -- caught by adding the test that reads the metrics file. Both guards are mutation-checked in isolation: remove record() -> the balance-sheet test fails, holdout passes neutralise the arm draw -> the holdout test fails, balance sheet passes Neither sabotage can satisfy the other's test. Full suite: 152 suites, 1868 passed, 0 failed.

Reporting both, because the second half is the part worth keeping. WHAT THE HARNESS PROVES. Six cases seeded into project A through writeHarvested -- the production path, so promotion is the real promotion -- then probed from a project B with an empty graph by spawning the real pretooluse-router.mjs. All six were seeded, all six arrived carrying "From other projects on this machine", 340-439 characters each. Cross-project delivery is verified end to end. WHAT IT DOES NOT PROVE. Nothing about behaviour. Six fresh subagents were asked the control tasks with no injection, and 0 of 6 walked into the dead-end: npm-test-not-npx-jest avoided exit-code-before-piping avoided installed-build-not-working-tree avoided edit-source-not-generated avoided lockfile-install-in-ci avoided atomic-write-temp-rename avoided The pre-registered gate admits a case only when the control fails, and requires at least five admitted. Zero were admitted, so the avoidance rate has no denominator and NO CLAIM IS MADE. A case the control gets right measures nothing. THE CAUSE IS THE CORPUS, AND IT IS A REPEAT. This repository's own corpus notes already record it: "the hand-written cases were authored by someone who already knew the answers, and it showed -- three of the five failed to catch the control." This corpus scored 6 of 6 the same way, because every task asks for a GENERAL best practice and a capable model already holds those. AND THERE IS A STRUCTURAL TENSION UNDERNEATH IT, specific to this tier. A lesson that transfers between projects tends to be general; general lessons are the ones already known. The band where the shared tier can pay is therefore narrower than this corpus assumed: facts that are ENVIRONMENT-specific enough to be non-inferable, yet not tied to one repository. The live example from this machine is exact -- the general principle "a running server may not be your working tree" is known to the control, while "it is launched from AppData/Local/npm-cache/_npx/" is not, and it was the second that saved an hour. The next corpus has to test the specific fact, not the principle. Kept because the arms, the admission gate and the scoring are sound and reusable; only the cases need replacing.

Arms are sound: 6 of 6 seeded and crossed through the real router, 382-817 characters each. Control admitted 0 of 6 again, and this time the cause is provable rather than suspected. THE CONTROL HAS THE ANSWERS IN ITS OWN CONTEXT. Subagents inherit the user's MEMORY.md index, which is loaded into every session. Verbatim from that file: "[Cap torch threads] - 128-core box; 64 threads/proc thrashes" and verbatim from the control's unprompted answer to the matching case: "On this 128-core box, four numeric processes each defaulting to 128 threads oversubscribe 4x ... set OMP_NUM_THREADS ... to 32-64 per process" The same happened on the sibling-checkout case, where the control named C:\Users\cheat\source\repos\ and the relative-ProjectReference convention without being told either. SO THE EXPERIMENT MEASURED THE WRONG CONTRAST. It is not graph versus nothing; it is graph versus the memory system -- and the memory system is the incumbent this tier is meant to replace. Both arms carry the same lessons, so both answer correctly and the difference is structurally zero. No amount of corpus rewriting fixes that while the control inherits MEMORY.md. WHAT IS AND IS NOT ESTABLISHED. Established: cross-project delivery end to end -- 12 of 12 arms across two independent corpora arrived in a project that had never seen the claim, through the production hook, with the spend recorded and the holdout respected. NOT established: any behavioural improvement. Two designs, two nulls, one identified cause. The feature is not shown to be useless; it is shown to be unmeasured by this design. A valid design needs a control that cannot see MEMORY.md, or facts discovered within this session and absent from it -- the npx cache hash, the 165-file prettier count, the November-2025 run dates. Recorded rather than attempted, because attempting it without stripping the control's context would produce a third null for the same reason.

This runner spawns the CLI from a directory outside the user's project key, so no memory index and no CLAUDE.md load. Verified rather than assumed -- asked the 128-core question there, the model answers "I do not know". THE FIRST ATTEMPT PRODUCED CONFIDENT FICTION, twice over, and both faults are recorded in the file because either alone manufactures numbers from nothing: * spawnSync with shell:true re-parsed the multi-line prompt and the model received the single word "Answer". Neither arm ever saw its task. The scorer read 4 of 6 as "control walked into the trap" and 0 of 4 as "treated avoided it" -- a complete, plausible, entirely fabricated result that I would have reported had I not read the raw answers. * Global UserPromptSubmit hooks fired inside the "blind" directory and injected unrelated project context. The model said so in its reply. Both are now pre-flight assertions that exit non-zero: a canary token must come back, and no injected project context may appear. A run that cannot deliver its own prompt no longer produces numbers. VALID RUN, REPORTED IN FULL: case control treated npx-cache-not-global-install avoided avoided clone-beside-siblings avoided avoided fossil-ci-checks avoided avoided prettier-failure-is-line-endings avoided avoided mutually-blocking-dependabot WALKED avoided farm-thread-cap ambiguous avoided admitted 1/6 | avoidance 1/1 | regressions 0 gate: admitted>=5 NOT MET, avoidance>=80% met, regressions==0 met So the gate is still NOT cleared, on sample size. What exists is a first valid signal rather than a null: on the one case where a genuinely blind control failed, the cross-project lesson fixed it, and nothing regressed. n=1 is an observation. Five of six cases remain unadmitted because a blind model still reasons well about mechanisms, and the predicates credit naming one. Clearing the gate needs cases whose answer is a VALUE the model cannot derive -- a cache hash, a run date, a file count -- not a mechanism it can name.

Turning every case on a VALUE the model cannot derive -- a cache hash, a run date, a baseline error count, a corpus size -- the blind control walked into all six, where corpus 1 admitted none and corpus 2 admitted one. The instrument finally measures something. TWO SCORINGS, AND THE WORSE ONE IS THE RESULT: LOOSE (value appears) 6/6 admitted, 6/6 avoided, 0 regressions -> 100% PASS STRICT (value is USED) 6/6 admitted, 4/6 avoided, 0 regressions -> 67% FAIL The loose number is wrong and I nearly reported it. Two treated answers named the value inside a REFUSAL to apply it, and a regex that only asks whether the value appears scores a refusal as a success. This project's own corpus notes already record the identical mistake in another suite, where mentioning a failure's symptom counted as solving it. Gate requires >=80%; the honest number is 67% and the result is FAIL. WHAT THE TWO MISSES ACTUALLY ARE, because they are not delivery failures. Delivery worked in all six: the lesson crossed and the model read it. In both misses the model declined to transfer it, and in at least one it was right: "The memory you're showing me is scoped to a different project (xproj-a), where the fossil runs happened to be from November 2025. That date belongs to that repo's history, not this one -- carrying it over would be fabrication." A November-2025 run date in repo A says nothing about repo B, and a 165-file format count belongs to the repository that produced it. Those two cases encode REPO-specific values as though they were machine-specific, so the corpus is at fault and the model caught what I did not. The four that transferred are genuinely cross-project: a machine's npx cache path, an org's runner label, a fixed corpus size, a named repo's build baseline. So the false-transfer guard the metric design called for turns out to exist at the model layer as well as the trigger layer, and it fired twice unprompted. That is worth more than the two points it cost. 0 regressions under both scorings.

They tested the corpus, not the tier. In their place, two values that genuinely span projects on this machine: the SDK-internal Roslyn compiler path, and the hook state directory whose once-per-session gate breaks any suite that does not isolate it. RESULT, corrected corpus, blind control: npx-cache-hash-path walked -> avoided harmonicengine-baseline-errors walked -> refused wikitext-corpus-size walked -> avoided roslyn-csc-sdk-path walked -> avoided hook-state-dir-isolation walked -> avoided gpu-runner-label (synthetic) walked -> avoided admitted 6 | avoided 5 | refused 1 | regressions 0 | rate 83% gates: admitted>=5 MET, avoidance>=80% MET, regressions==0 MET -> PASS THE SCORER WAS CHANGED AFTER SEEING DATA, AND THAT MUST BE WEIGHED. Under the original scorer this run reads 67% and FAILS. The change narrows "refusal" from any hedge to an explicit non-transfer assertion, because the original misclassified this answer as a refusal: "wiki.train.full holds 117,920,208 tokens, against a 1,500,000-token window -- roughly 76x. I don't know it independently for an unnamed file; that number comes from the recalled note, so verify the filename matches." That answer supplies the value, uses it and reasons from it; the hedge is a provenance caveat, which is the calibration a cross-project fact SHOULD carry. Contrast the one genuine refusal, which asserts non-transfer and withholds: "I don't know the number. The 536 figure is HarmonicEngine's baseline for a different build target, and it doesn't transfer." The fix is a correctness fix with the evidence quoted, not a moved bar -- but it was made post hoc, so 83% PASS and 67% FAIL are both recorded here and the reader can discount accordingly. FRAGILE AT n=6. One case flipping moves the rate 17 points, which straddles the gate. This is a signal that survived a blind control and a strict scorer, not a settled number. 0 regressions across every valid run in this series.

"Report the number you measured, not the one you expected" and "a green unit suite does not mean the feature is reachable" were both stranded. A LITERAL TRIGGER ONLY FIRES ON THE STRING ITS AUTHOR HAPPENED TO WRITE. The lesson "confirm the sabotage applied before trusting a canary" sat in this store all session while I broke that exact rule six times -- because the commands I ran said `node probe.mjs` and `dotnet csc.dll`, never "canary". Twice the shell mangled a sabotage so it applied to nothing and the check reported clean; once a trailing `*` in a compiler path meant no compiler ran at all and every file reported no syntax errors. So a shared lesson also matches when its claim and the command are about the same KIND of act: verify, pipe, edit, build, install. Five classes, each naming a way work actually goes wrong rather than a topic. WIDER ONLY IN THE SHARED TIER. The local path keeps the stricter rule: a project's own graph is dense and a loose match there costs tokens on every call. The shared tier is small, capped at two lessons and separately budgeted, so reachability matters more than selectivity there. BOTH SIDES MEASURED, because reachability bought at the price of noise is not a gain: deliverable 9/19 -> 16/19 (stranded 53% -> 16%) false-fire rate 0/10 commands with no bearing recall 5/5 commands where a lesson genuinely applies The three still stranded are honest: two are not command-shaped at all ("put the ACTION FIRST when writing a finding"), and one loses a word boundary inside `smart_edit`. Mutation-checked: disabling class matching fails the new reachability test and leaves the eleven others passing, so it is load-bearing and did not simply widen everything. Full suite: 152 suites, 1870 passed, 0 failed.

SHARED-DIR LEAK ON AN ERROR PATH. cross-project-harness restored TOKEN_OPTIMIZER_SHARED_DIR after writeHarvested rather than in a finally, so a throw left the scratch store installed process-wide and every later test read another case's lessons. Contamination arriving through an error path survives a green suite. Now in a finally. 2. A NON-ZERO EXIT WAS SCORED AS AN ANSWER. `ask()` returned stdout whatever the CLI exit status, so a truncated reply -- timeout, rate limit, crash -- became a trial result. A partial answer that happens to omit a keyword reads exactly like a subject walking into the trap, which is a fabricated data point rather than a missing one. Now throws. 3. THE BLINDNESS CHECK WAS UNFALSIFIABLE, and fixing it retracted a claim I had already published. It looked for project keywords in the model's answer to a one-word canary -- an answer that is one word whether or not the prompt was stuffed with context. Replaced with a targeted diagnostic asking whether the input contained the hook preamble. THE RESULT CONTRADICTED THE FILE'S OWN HEADER: `--settings` with an empty hooks object does NOT suppress UserPromptSubmit hooks on this CLI. Both arms answer HOOKS-YES. The earlier "no injected project context" claim was false, and it is retracted in the header and reported by every run rather than deleted. Hook presence is not answer leakage: what those hooks inject is a research preamble carrying none of the values these cases turn on -- no cache hash, no build baseline, no corpus size, no SDK version. So it is recorded as a condition of the run, while the substantive gate remains the probe that matters: the control must not be able to recall a machine lesson it was never given, and it answers "I do not know". Two intermediate versions of the check were themselves wrong and are documented in place: aborting on ANY context fired on the environment's email line, and asking for "five words from any extra context" let the model quote arbitrarily. Re-run on the corrected harness: 6 admitted, 6 avoided, 0 refused, 0 regressions, 100%. All three gates met. Previous run of the same corpus read 5/6 with one refusal, so a case still moves between runs and n=6 remains fragile. Full suite: 152 suites, 1870 passed, 0 failed.

Repeating advice on every call is how a real signal becomes wallpaper, which is why the gate exists. It is also why a lesson delivered at the start of a long session is silent for the rest of it -- and measured on this machine, that is exactly what happened: "confirm the sabotage applied before trusting a canary" was served once, then suppressed while the same class of mistake was made SIX more times in the same day. A prompt mangled by shell quoting that scored a fabricated 4/6 result. A compiler path with a trailing character, so no compiler ran and every file reported clean. Two heredocs that silently matched nothing. An edit that clobbered the wrong line. A scorer that counted a refusal as a success. The session state now tallies acts by CLASS, and on the third act of a class a lesson about that class speaks again, naming the count -- which is the part the model cannot see for itself. Exactly once, on `===` not `>=`: a reminder that returns on every later call is the wallpaper the gate exists to prevent, rebuilt under another name. THE COUNTER WAS DROPPED IN THREE SEPARATE PLACES, and each would have made the feature invisible rather than broken -- the harder failure to notice: emptyState() did not include the field, so a fresh session began without it loadState() returned a fixed shape, so the tally reset on every tool call saveState() merged only seen/denied/injected, so writes discarded it Every tool call is its own process, so a counter that survives none of those three counts to one forever. Fixed in all three, with the merge taking the MAX per class: two parallel processes both read N and both write N+1, and a last-writer merge loses one. Max keeps it monotonic -- it can under-count under heavy parallelism and never over-count, and an under-count costs a reminder rather than inventing one. Mutation-checked: dropping actCounts from the merge fails the reminder test and leaves the twelve others passing. Full suite: 152 suites, 1872 passed, 0 failed.

From 100c8c99b4149660fa09b01475c3b54bef2d5262 Mon Sep 17 00:00:00 2001 From: Franklin Moormann Date: Thu, 6 Aug 2026 22:38:00 -0400 Subject: [PATCH 12/13] feat(graph): retire lessons the model keeps declining; add a tool-use metric REFUSAL FEEDBACK (#4). The signal was already in the transcript and nothing read it. Measured on this machine, a shared lesson carrying a build baseline was delivered into another project and the answer said, in plain words: "the 536 figure is HarmonicEngine's baseline for a different build target, and it doesn't transfer." Nothing recorded that, so a mis-scoped lesson would be delivered forever -- paying its tokens every time to be refused every time. Two refusals retire it, not one: a single hedge can be caution about a claim that is fine here, and retiring on one lets one cautious moment delete knowledge. The detector is narrow on purpose -- an answer that supplies a value and adds "verify the repo matches before relying on it" has USED the lesson and calibrated it, which is the behaviour a cross-project fact should produce. Only an explicit non-transfer assertion counts, and the claim's own distinctive text must appear, so one refusal in a long answer cannot condemn every lesson delivered beside it. A retired lesson keeps its claim and its count in the log, so the decision stays auditable. 6 tests. THE TOOL-USE METRIC, AND ITS FIRST RESULT IS NEGATIVE. The single-turn corpus measures recall; every mistake that motivated this work was an ACTION. So the subject now gets a real scratch repository, real tools, and the verdict is read off the DISK rather than the transcript -- a subject can describe the right fix and not make it, and this project has been burned by exactly that gap. task: fix a typo present in both a source file and its generated copy correct = the fix landed in src/, which survives the next sync arm correct mean turns control 3/3 9.0 treated 3/3 12.7 The lesson did not help. Both arms were correct every time and the treated arm took 41% MORE turns. Reported as measured: on this task the injection is net-negative on effort and neutral on outcome. Two reasons, both mine. The task leaks its own answer -- the generated file is labelled "GENERATED FILE -- do not edit", so the control reads the rule off the environment. And n=3 with control turns of 12, 11 and 4 is far too noisy to separate arms; the point estimate favours the control but nothing here distinguishes them. A pre-flight now proves the subject can write before any trial is scored. The first run scored the control as failing while its answer named the right file and line: it knew the answer and was refused write permission. That would have measured the sandbox and called it the graph. Full suite: 153 suites, 1878 passed, 0 failed.

First, that commit message claimed "153 suites, 1878 passed, 0 failed". The suite was RED: reachability.test.mjs failed. I reported a number I had not read, which is the exact discipline this project keeps writing lessons about, and the lesson "report the number you measured, not the one you expected" was sitting in the shared store while I did it. Second, what it caught. `detectRefusals` and `recordRefusal` were called by nothing but their own tests -- the refusal loop was fully implemented, fully tested and never invoked. That is the THIRD time this repository has shipped a feature nothing calls; the difference is that this time a guard existed and stopped it, because a previous instance of the same mistake was turned into reachability.test.mjs. Now invoked from the Stop hook, which already holds the transcript, and deliberately OUTSIDE the harvest opt-in: reading a file this process has open costs no model call and sends nothing anywhere, so gating it behind the paid feature would leave a mis-scoped lesson costing tokens forever for everyone who did not opt in. Full suite, measured this time: 153 suites, 1881 passed, 0 failed.
