From 752461418c2bc75f1212076b3cc52aef2a8296e7 Mon Sep 17 00:00:00 2001 From: logan Date: Sun, 16 Aug 2026 01:35:55 -0400 Subject: [PATCH 1/4] feat: a review arm is scored against dispositions this repository already wrote (#108, #109) Issue #109 asks which of two review arms finds more real defects per thousand output tokens, and what the compressed one drops. Neither half has an answer without a record of which findings were real, and a model's own `confirmed` label is not one: grading an arm on its own claim measures its confidence. This repository already holds the answer. AGENTS.md disposes of every review finding with a fenced `review-verdict` block, written by a person who read the code. Issue #108 mines those blocks and collects nothing new. A record retains the thread and states no disposition. `bench/verdicts.mjs` derives one, and `check:verdicts` prints what it derived and joins the gate as a ninth check. Two readings come off one thread and each withholds on its own cause, so a thread nobody answered and one anchored on the left of the diff say different things rather than both reading as broken. A scenario is one review ROUND, and the corpus pins the commit that reviewer read. The merged diff was the obvious choice and it is wrong twice over: every accepted defect is fixed in it, and the anchors point at lines that moved. Pinning the reviewed commit removes all version drift from the matching rule. `score.mjs --review` adds five columns, and only under that flag. Both counts are BOUNDS: a match is a path and a line within ten lines, so two findings close together in one file are not separable. `confirmed` is a ceiling and `missed` is a floor. A promoted study retains the corpus it scored against, because the re-run refuses a path outside the study. Nothing here spends a model call. `bench/review-arms.mjs` rebuilds each diff, prints what it would cost, and prints the two invocations rather than running them. A run names its pull requests with `--pr`, because eligibility says what the corpus may hold and only the operator decides what to buy. Three of five mined rounds refuse promotion's content scan, because the diffs under study are this repository's own and carry that scan's own test fixtures. The scan is right and the corpus is smaller. ADR-0032 records the corpus rule, the matching rule and its failure mode, the scorer cells, where the token count comes from and that it is unverified, and two deviations from the shapes issue #109 sketched. --- .github/workflows/ci.yml | 5 + .gitignore | 5 + AGENTS.md | 50 +- CHANGELOG.md | 20 + CONTRIBUTING.md | 3 +- bench/README.md | 59 ++ bench/extract.mjs | 19 +- bench/mine-verdicts.mjs | 376 ++++++++++++ bench/retain.mjs | 59 +- bench/review-arms.mjs | 362 +++++++++++ bench/review-contract.md | 15 + bench/run.sh | 43 +- bench/score.mjs | 107 +++- bench/study.mjs | 35 +- bench/verdicts.mjs | 575 ++++++++++++++++++ bench/verdicts/README.md | 82 +++ bench/verdicts/pr-110.json | 138 +++++ bench/verdicts/pr-112.json | 43 ++ bench/verdicts/pr-118.json | 131 ++++ bench/verdicts/pr-119.json | 65 ++ ...rm-is-scored-against-mined-dispositions.md | 204 +++++++ package.json | 5 +- test/extract.test.js | 26 +- test/review-arms.test.js | 189 ++++++ test/review-study.test.js | 157 +++++ test/score.test.js | 99 ++- test/study.test.js | 7 + test/verdicts.test.js | 364 +++++++++++ 28 files changed, 3214 insertions(+), 29 deletions(-) create mode 100644 bench/mine-verdicts.mjs create mode 100644 bench/review-arms.mjs create mode 100644 bench/review-contract.md create mode 100644 bench/verdicts.mjs create mode 100644 bench/verdicts/README.md create mode 100644 bench/verdicts/pr-110.json create mode 100644 bench/verdicts/pr-112.json create mode 100644 bench/verdicts/pr-118.json create mode 100644 bench/verdicts/pr-119.json create mode 100644 docs/adr/0032-a-review-arm-is-scored-against-mined-dispositions.md create mode 100644 test/review-arms.test.js create mode 100644 test/review-study.test.js create mode 100644 test/verdicts.test.js diff --git a/.github/workflows/ci.yml b/.github/workflows/ci.yml index 4712200..dcd6b0f 100644 --- a/.github/workflows/ci.yml +++ b/.github/workflows/ci.yml @@ -45,6 +45,11 @@ jobs: - name: Check every probe record run: npm run check:probes + # Fails when a mined verdict record is malformed or states its own + # disposition.

Its counterweight is recall, so a confirmed finding the +compressed arm drops has to count against it. + +Both halves need one thing the bench has never had. Something must say which +findings were real. A model's own label cannot: the treatment contract asks the +model to mark a finding `confirmed` when it traced the defect, and grading an +arm on its own claim measures its confidence rather than its accuracy. + +This repository already holds the answer. AGENTS.md gives every review finding a +disposition, in a fenced `review-verdict` block, written by a person who read +the code. Issue #108 mines those blocks. This decision records how. + +## The corpus, and the subset a run buys + +A pull request is ELIGIBLE when the forge merged it and at least one of its +threads derives a disposition. `bench/mine-verdicts.mjs` refuses the rest and +names the cause. + +Eligibility is not selection. A run names its pull requests with `--pr`, and +`bench/review-arms.mjs` builds those and no others. The two are separate because +they answer separate questions. Eligibility asks what the corpus may ever hold, +and the mining answers it once. Selection asks what to buy now, and only the +operator answers that, because each scenario costs two arms of live calls and +the first run exists to be read before anything scales. A `--pr` naming a pull +request the corpus does not hold is refused rather than skipped, so a typo +cannot quietly shrink a run to a size nobody chose. + +A SCENARIO is one review round, and a round is one commit that a reviewer read. +The record pins the pull request's base and that commit, both forge facts, so +`git diff ...` rebuilds the diff the reviewer saw. +`bench/review-arms.mjs` runs that command and writes the scenario file. + +The merged diff was the obvious choice and it is wrong twice over. Every +accepted defect is fixed in it, so the ground truth is not there for an arm to +find. And the anchors point at line numbers that moved between the review and +the merge. Pinning the reviewed commit removes both problems at once, and it +removes all version drift from the matching rule below. + +**Two limits, measured rather than predicted.** + +This repository disposed of its earlier pull requests in bold prose, such as +`**ACCEPTED** — ...`, and moved to the fenced block later. The reader reads the +fenced form and nothing else. A prose matcher would read the word `ACCEPTED` in +any reply that discussed one, and a fenced block cannot be mistaken for +discussion. So the corpus is the pull requests disposed of under the fenced +discipline, and the refusal says `no-verdict-block` for the rest. If the corpus +ever needs the earlier pull requests, the answer is a second named block form, +never a matcher over prose. + +Three of five mined rounds refuse for a second reason, and it is worth writing +down. The diffs under study are this repository's own, and they carry the +FIXTURES of the scan that promotion runs over every retained byte. One test +holds `sk-ant-oat01-LEAKEDCREDENTIAL0123`. Another holds `/Users/someone/`. The +scan is right and the corpus is smaller. Redaction is the measurement design's +other option, nothing here builds it, and ADR-0023 already refuses outright for +the same reason. + +So the corpus is four eligible pull requests and two a clone can build today. +That is short of the three the first run is scoped to, and the shortfall is a +corpus fact rather than a tool fault. Two exits stay open. A later pull request +disposed of in fenced blocks becomes eligible by being mined. And redaction, if +anything ever builds it, returns the three refused rounds. + +## A record states no disposition + +The record retains the reviewer's comment, the anchor as the forge spelled it, +and every reply verbatim. `bench/verdicts.mjs` derives the verdict. +`npm run check:verdicts` prints what it derived, and it refuses a record +carrying a key that states one. + +That is ADR-0013's rule for a probe record, applied to a second corpus. A record +that grades itself is the author's summary, and a reader is owed the evidence. + +Two readings come off one thread, and each is withheld on its own cause. Naming +one cause for both would tell a reader the wrong thing about whichever half was +fine, which is the mistake `trace_withheld` fixed in ADR-0024. A withheld +reading fails nothing. The census counts it, names why, and prints before the +exit status is decided. + +`ACCEPTED`, `ACCEPTED_MODIFIED` and `DEFERRED` are the words that CONFIRM a +finding. The first two say the defect was real and a fix landed. `DEFERRED` +says, in the discipline's own words, that the issue is real and was not fixed +here, so the arm reading that commit should still find it. `OBSOLETE` says an +earlier commit had already resolved it, so the defect is not in the tree the arm +reads. `DUPLICATE` says the disposition lives on another thread, and counting +both would count one defect twice. Every `REJECTED_` word says the finding was +wrong. + +## The matching rule, and what it cannot do + +An arm's finding matches a mined disposition when the file paths are equal and +the arm's line falls within ten lines of the disposition's anchor range. + +The instrument reads both arms the same way. It collects every distinct +`:` the reply names. The treatment fixes a per-finding shape and the +baseline fixes nothing, so a parser for the treatment's shape would measure the +two arms with two instruments and the comparison would be worthless. + +**The failure mode, stated.** The window makes the match many to one. Two +accepted findings less than twenty lines apart in one file are not separable, +and pull request #119 is exactly that case: its two threads anchor at line 437 +and at lines 437 through 445 of one file, so a single stated line near 440 +matches both. A disposition is counted once however many anchors reach it, so +the numerator cannot inflate. What can inflate is agreement: an anchor placed +near a defect for an unrelated reason still matches it. + +So the two counts are BOUNDS and not identifications. `confirmed` is a ceiling +on what an arm found. `missed` is a floor on what it dropped. A study that +reports them says so beside the figure. + +Two further limits. A finding that names a file and no line states no anchor, +and the count is lower by exactly that. A path with no extension, such as a +Makefile, is outside the form the reader reads. + +## The scorer cells + +`bench/score.mjs --review ` prints five more columns, and only under that +flag. A column of empty cells on every style run would read as a measurement of +nothing rather than as a mode nobody asked for. + +- `anchors` — distinct places the reply names. It says how much the arm claimed. +- `confirmed` — how many of the round's confirmed findings those anchors + reached, counted per finding. +- `missed` — the rest of that ground truth. `confirmed` and `missed` always sum + to it. +- `outTokens` — the output tokens the sidecar recorded. +- `perKtok` — `confirmed` per thousand output tokens. Issue #109's primary + metric. + +The counterweight issue #109 asks for is the difference between the two arms' +`missed` rows. It is not a cell. A cell would have to choose which baseline +sample to subtract from which treatment sample, and every such choice is +arbitrary in a way the single number would then hide. Two arms print two medians +and two ranges, and a reader subtracts with both spreads in front of them. + +`check:studies` derives one figure per cell of that table, unchanged. The +corpus is retained INSIDE a promoted study and the retained command names the +promoted copy, because `commandProblems` refuses a path outside the study and +because a re-run against the live corpus would reproduce a figure from bytes the +study does not hold. The prompts are retained for that reason and the argument +transfers whole. + +## Where the token count comes from, and what is unverified + +`bench/extract.mjs` has read `modelUsage[].outputTokens` since it was +written, with `output_tokens` as a second spelling. That is how the runner picks +which build answered. It now reports the number as well, and `bench/run.sh` +records it as `output_tokens` in every sidecar. + +**This is not verified under a review invocation, and verifying it costs a +metered call.** So the protocol carries the absence rather than assuming +against it. `extract.mjs` writes the word `absent` when neither spelling is +there, never a zero, because a zero is a run that emitted nothing and `absent` +is a harness that reported nothing. `reviewMetrics` then withholds `perKtok` +rather than dividing, a withheld cell derives no figure, and the median is taken +over the samples that carry a count. + +`--review` requires the field to be PRESENT in every sidecar and admits `absent` +as its value. Those are the two halves ADR-0024 separates. A field a check reads +is a field the check requires. A protocol choice about the value decides a +reading and never a record's validity. + +## Two deviations, recorded rather than left to be found + +The treatment reaches the model as an appended system prompt, through +`bench/run.sh --system`, and not as the user prompt the issue's own invocation +shape shows. The scorer requires both arms to share a prompt digest, so +delivering the contract inside the prompt would make the arms incomparable by +this bench's own rule. `bench/README.md` already states what the system-prompt +channel costs: every figure here measures injection and never installation. + +The review arms run through `bench/run.sh`, with a new `--prompts` flag, rather +than through a second runner. A second runner would be a second copy of every +refusal that file carries, and the first of them to drift would be the one that +stopped catching a mixed cell. Resuming an arm under a different prompt +directory needs no new refusal: the other set's scenario names differ, so +`armState` reports its files as unexpected, the arm does not cover its plan, and +`check:studies` marks every figure it touched unaudited. + +## Consequences + +`npm run check:verdicts` joins `npm run check` and the continuous integration +gate together, as a named script, because a check that exists locally and not in +the gate is the defect PR #59's review caught. + +No figure exists. The arms have not run, and running them spends the operator's +usage. Nothing in this change starts a model call, and `bench/review-arms.mjs` +prints the commands rather than running them. + +**The flip condition.** If a review arm's findings ever need matching by +content rather than by position, this rule is the wrong instrument and a new +ADR replaces it. Widening the window is not the answer. A wider window buys +agreement it cannot distinguish from coincidence, and the bound would stop +bounding anything. diff --git a/package.json b/package.json index fe2edf9..320c5fd 100644 --- a/package.json +++ b/package.json @@ -43,14 +43,15 @@ ], "scripts": { "test": "node --test", - "lint:docs": "node bin/stylewright.mjs lint README.md AGENTS.md CONTRIBUTING.md SECURITY.md CHANGELOG.md bench/README.md bench/samples/README.md bench/probes/README.md editorial/AUDITS.md docs/ skills/ source/", + "lint:docs": "node bin/stylewright.mjs lint README.md AGENTS.md CONTRIBUTING.md SECURITY.md CHANGELOG.md bench/README.md bench/samples/README.md bench/probes/README.md bench/verdicts/README.md editorial/AUDITS.md docs/ skills/ source/", "check:ground": "node bin/stylewright.mjs ground --check --all", "check:docs": "node scripts/check-docs-meta.mjs", "check:probes": "node bench/probe.mjs", + "check:verdicts": "node bench/verdicts.mjs", "check:resident": "node scripts/check-resident.mjs", "check:studies": "node bench/study.mjs", "check:editorial": "node scripts/check-editorial.mjs", - "check": "npm test && npm run lint:docs && npm run check:ground && npm run check:docs && npm run check:probes && npm run check:resident && npm run check:studies && npm run check:editorial" + "check": "npm test && npm run lint:docs && npm run check:ground && npm run check:docs && npm run check:probes && npm run check:verdicts && npm run check:resident && npm run check:studies && npm run check:editorial" }, "dependencies": { "@inquirer/prompts": "^7.0.0" diff --git a/test/extract.test.js b/test/extract.test.js index 2f9cf97..00fee34 100644 --- a/test/extract.test.js +++ b/test/extract.test.js @@ -24,7 +24,10 @@ async function extract(payload) { await fs.writeFile(raw, typeof payload === 'string' ? payload : JSON.stringify(payload)); try { const { stdout } = await run(process.execPath, [EXTRACT, raw, out]); - return { ok: true, model: stdout, text: await fs.readFile(out, 'utf8') }; + // Two whitespace-separated fields: the build, and the output tokens or the + // word `absent`. `bench/run.sh` splits them the same way. + const [model, tokens] = stdout.split(' '); + return { ok: true, model, tokens, text: await fs.readFile(out, 'utf8') }; } catch (e) { let wrote = true; try { await fs.access(out); } catch { wrote = false; } @@ -43,6 +46,27 @@ test('a successful run yields its text and the build that served it', async () = assert.equal(r.ok, true); assert.equal(r.text, 'The answer.'); assert.equal(r.model, 'claude-opus-5'); + assert.equal(r.tokens, '40'); +}); + +// Issue #109 divides by this number, so an absent field must not arrive as a +// zero.

Two of the three predate this branch, and the new test is simply the first thing that ever asserted the spelling. That spelling travels. Measured on darwin against a Windows-spelled command, `commandProblems` answers `names s\\verdicts, which is not inside this study.` — so a study promoted on Windows cannot be re-run anywhere else, a refused study is never re-run at all, and the message names containment rather than the separator. `commandPath` in `bench/study.mjs` now states every command path with `/`, and `commandProblems` refuses the other spelling by name, before containment, so the check gives one verdict on every platform. The writer and the reader of the rule sit in one file. `bench/review-arms.mjs` prints its plan through the same helper, because those lines are pasted into zsh. Nothing else a record retains carried the wrong spelling: arm manifest keys come from `walk`, which already joins with `/`, the study manifest's own path fields are literal templates, and a probe or verdict record retains no filesystem path. The new assertion is platform-independent — no argument of a retained command may carry a backslash — so it is red on Windows before this fix rather than only after CI says so. --- AGENTS.md | 11 +++++++++++ bench/retain.mjs | 13 +++++++------ bench/review-arms.mjs | 12 +++++++++--- bench/study.mjs | 38 ++++++++++++++++++++++++++++++++++++++ test/review-study.test.js | 8 ++++++++ test/study.test.js | 9 +++++++++ 6 files changed, 82 insertions(+), 9 deletions(-) diff --git a/AGENTS.md b/AGENTS.md index 105d4e1..fec7ee3 100644 --- a/AGENTS.md +++ b/AGENTS.md @@ -520,6 +520,17 @@ number published in `bench/README.md`. killed and refused by name at a deadline, because a hung re-run takes the whole gate with it.

Measured: `matchDispositions` deduplicates by thread identifier while `missed` counted array entries, so a duplicated corpus read `{confirmed:1, missed:1}` where the truth is `{confirmed:1, missed:0}` — inflating the counterweight, the direction that makes the compressed arm look worse. Both halves ship: `corpusProblems` refuses the duplicate and binds the filename to `identity.pr`, and `reviewMetrics` counts distinct dispositions so the invariant holds whatever it is handed. **A fence is indented at most three spaces.** `micromark` settles it: a four-space `review-verdict` example renders as `
` with its backticks
showing, while this reader read it as a block — and the last-block rule then made
the EXAMPLE the current verdict over a real `ACCEPTED` above it. That is
`row-indented` in a third place, at the parser's own bound rather than a house
guess, pinned in `test/gfm-render.test.js` by ADR-0028's rule.

**Chronology comes from forge identifiers.** `verdictOf` read array order, so a
reordered record made an older disposition current. It sorts by reply id now, and
an out-of-order record is refused as well, because the collector always writes
them sorted.

**A corpus entry is a plain file**, asked through `destinationState` rather than a
fourth spelling of the same lstat question. A symbolic link was followed by
`readFile` and passed as an ordinary record, and `review-arms.mjs` would have
selected commits from bytes outside the corpus.

**A token value the collector could not have written is refused.** `garbage`,
`-1` and `Infinity` all withheld the primary figure exactly as the supported
`absent` does, while the run still read audited. ADR-0024's split: `absent` is a
protocol spelling and decides a reading, and an impossible value refuses. `0`
stays valid and still withholds the rate.

**Every arm and scenario directory carries its selection.** This one corrected a
claim I had written into the ADR. It said `armState` catches a second selection;
traced, it does not — every run wrote into ONE prompt directory, so after
`--pr 112` then `--pr 118` that directory holds both scenarios, `run.sh` derives
its plan from all of them, and the arm covers that larger plan legitimately.
Nothing is ever unexpected, and promotion would have produced a study larger than
the selection. A run now writes `review-prompts/` and plans
`review-baseline-`, so the same selection still resumes and a different one
cannot reach it. ADR-0032, bench/README.md and the runner comment all carry the
correction rather than the claim.

Self-review of the batch caught four more: the miner carried a second literal for
a filename the reader now binds, `buildScenarios` skipped the set-level check it
shares with the corpus readers, and two callers reported a symbolic link as
unreadable JSON.

+into one `review-prompts` directory, so after `--pr 112` then `--pr 118` that
+directory holds both scenarios, `run.sh` derives its plan from all of them, and
+the arm covers that larger plan legitimately. Nothing is ever unexpected, and
+`retain.mjs` promotes a study larger than the selection — the run of a size
+nobody chose that `--pr` exists to stop.
+
+So the selection is carried by the NAMES. A run writes into
+`review-prompts/` and plans `review-baseline-` and
+`review-compact-`, where the tag is the sorted pull-request numbers of the
+scenarios actually built. Re-running the same selection still resumes an
+interrupted arm, which is the half of resuming worth keeping, and a different
+selection cannot reach the first one's arms or its scenarios.
