timothyandtimothy	469d19852c	fix(788): one declarative H10 verdict vocabulary, derived by both sides (#846) ... The verdict words lived in two hand-written shell copies — the `case` arms of post-review-verdict.sh (write) and the POS_RE/NEG_RE regexes of check-review-verdict.sh (read) — held together by nothing but a comment that had already gone stale. scripts/lib/review-verdict-vocabulary.sh now declares them once and both sides derive; neither script enumerates a verdict word any more. Only the WORD SET moved. The grammar stays in check-review-verdict.sh, where every #629 false-open actually lived. No parity test: #774 shipped one and withdrew it after six rounds, because a regex over shell source is not a shell parser. The proof is behavioural and graded MUTATION — the harness restores the pre-#788 hardcoded POS_RE each run and requires it to redden. Enforcement is a DATA dependency, not a control-flow gate. Review round 1 found a real fail-open in the first commit: `${#arr[@]}` is nounset-safe only for a declared-empty array, and under `set -u` that error inside a function called as `if ! validate` skips BOTH branches — so on the reader (deliberately no `set -e`) an explicit BLOCKED @ head classified `positive`, exit 0. Validation now sets a sentinel on its last line and the derived views refuse without it. Six cold review rounds; rounds 2-6 found no fail-open across differential fuzzing (4788 / 2612 / 7560 payloads, zero divergences from origin/main's grammar), sentinel forgery, environment poisoning, declare -p evasion on bash 5.3 and 3.2, path/symlink resolution and probe TOCTOU. Every malformation fails closed: reader exit 2, writer exit 1 with nothing posted. Also corrected: CLAUDE.md and release.review-verdict-gate both enumerated the vocabulary without LGTM, a word the code has accepted since #629. fixes #788 Co-authored-by: Timothy <timothy@noreply.gitea.tblindustries.be>	2026-08-26 20:58:09 +00:00
timothyandClaude Opus 5	50bcd7b0c7	fix(629): strip raw HTML blocks, and state where the hardening stops ... Round 5: raw HTML is the third code-block form. `<pre>`, `<code>` and HTML comments all render their contents literally, so a verdict inside one is an example, not an approval: <pre> / <code> / <!-- ... --> containing a verdict -> positive Now stripped, tracked as a marker count rather than parsed — the direction of error is to strip MORE, which can only ever withhold approval. Mutation-verified: removing the stripper fails all five cases. AND THE HARDENING STOPS HERE, deliberately. The record now says so, because otherwise the next session re-derives it: this is a best-effort heuristic, not a markdown parser. It covers the three code-block forms markdown has (fenced; indented, via the column-0 rule; raw HTML) and is not proof against every way to render text as non-prose. Stopping is safe because the comment is NOT the load-bearing gate. Since #622 the authoritative signal is the `review-verdict/h10` commit status, written only by post-review-verdict.sh from explicit arguments — a comment cannot forge it. This classifier is condition (c) of the PreToolUse hook: defense in depth on an agent's merge call. A residual false-open means the hook does not object; it does not mean a merge happens. Five rounds found five code-block forms, four of them introduced while fixing the previous round. The generalisable rule, now in the record: when a heuristic keeps failing at the edges, check whether it is actually the thing enforcing the invariant before spending another round on it. Also measured, against the real corpus: a "verdict must be the first line" rule would have killed every code-block form at once, but 14 of 18 verdict markers ever posted in this repo are NOT on the first line — so it was rejected as a retroactive break, not deferred. 178 tests. refs #629 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Decisions-Edit: yes	2026-07-26 01:14:59 +02:00
timothyandClaude Opus 5	28a9d0dbfd	fix(629): round-4 — require the marker at COLUMN 0, narrowing the grammar instead of patching again ... Round 4 found the last false-open: markdown has a SECOND code-block form the fence stripper does not cover — indented blocks (4 spaces or a tab). A pasted indented example still self-approved: Example: Review-verdict: MERGEABLE @ <head> -> positive Adding an indented-code stripper would be the same move that produced rounds 2, 3 and 4: fixing the instance, not the class. So the grammar is narrowed instead — the marker must sit at COLUMN 0. That kills every indentation-based ambiguity at once (4-space, tab, list-nested, arbitrary indent). Cost, accepted deliberately: a verdict indented under a list item is now ignored and classifies `absent`, which asks a human. For a gate, erring toward ignoring is the safe direction. Fence detection KEEPS its leading-whitespace tolerance, because stripping more is always safe. `test_leading_indent_is_tolerated` asserted the old behaviour and is replaced by `test_falseopen_an_indented_verdict_is_not_a_verdict`, parameterised over four indent shapes and mutation-verified: restoring `^[[:space:]]*` fails all four, control green. 172 tests. Round 4 verified clean by execution: the rc plumbing fails closed for a forced failure in the inner jq, awk, grep AND the pipeline producer (rc 3/4/5/93 -> exit 2); fence-length semantics, mismatched markers, CRLF fences, 10-marker fences, blockquote fences; emoji, CRLF, a 120k line, 200 comments; NUL rejection with no JSON-encoding bypass. refs #629 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Decisions-Edit: yes	2026-07-26 00:52:11 +02:00
timothyandClaude Opus 5	299e7b27af	fix(629): round-3 fixes — fence LENGTH semantics, and stop masking reader failures ... Third review round, third set of real findings. Both reproduced before fixing. 1. High: markdown closes a fence only with N-or-more of the SAME marker it was opened with, so a ```` block legitimately CONTAINS a ``` line as content. Toggling on any 3+ marker left the fence at that inner line and graded the verdict below it as a real approval: ````text / ``` / Review-verdict: MERGEABLE @ <head> / ```` -> positive Now tracks the opening marker's character and length; a shorter or different marker while a fence is open is content, so it neither closes the fence nor escapes it. 2. Medium: `awk ... | grep ... || true` flattened "no match" (grep rc 1, normal) together with a real tool failure (rc >= 2). A failing reader produced no verdict lines at all — `absent` — silently discarding a real BLOCKED verdict. awk and grep are now checked separately, and only "no match" is tolerated. Also fixed while writing (2): `[ rc = 0 ] && printf` as the loop body's LAST command would leave the subshell exiting 1 whenever the newest comment carried no verdict, which the rc check would then report as a failure to read comment bodies — an ordinary PR reading as broken. Uses an `if`. 169 tests. Both findings mutation-verified: restoring the naive fence toggle fails all four longer-fence cases, restoring `|| true` fails the failing-grep case, control green. Verified the ordinary shapes still work: plain ``` and ~~~ fences and lang-tagged fences still stripped, an unclosed fence still swallows, a real verdict beside a fenced example still counts, and a fenced positive alongside a real BLOCKED still classifies negative. refs #629 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Decisions-Edit: yes	2026-07-26 00:47:40 +02:00
timothyandClaude Opus 5	f151b93245	fix(629): review fixes — tilde fences, an unbounded sha field, and a forgeable comment boundary ... Cross-family review of 38a96f47 returned BLOCKED with three findings. All reproduced first: ~~~ fence -> positive fences were stripped for ``` only; markdown also takes ~~~ @ <40hex>f / ZZZ -> positive the sha matched {7,40} with NO right boundary, so an over-long or malformed token was TRUNCATED into a passing one \x01BODY-BOUNDARY\x01 -> positive an in-band separator joined comment bodies, so a body containing that line forged a boundary, reset fence state mid-comment, and exposed a verdict inside an unclosed fence Fixes: both fence markers honoured; the hex run matched whole, required to end at a non-alphanumeric boundary, with its length validated separately so an out-of-range token is rejected rather than trimmed to fit; and bodies carried OUT-OF-BAND (one JSON-encoded string per line), which removes the forgery class instead of escaping the sentinel. The third is the one worth remembering: an in-band delimiter is forgeable by whoever writes the data, and here that is anyone who can comment on the PR. Two of these fixes broke previously-green tests, both of which were right to break: - an over-long token now classifies `no-sha`, not `stale`. The fixture asserting `stale` was 45 hex chars, so it had been exercising the length guard while claiming to test the prefix rule. Rebuilt as a well-formed 40-char sha that contains the head prefix without starting with it. - `jq -e` exits 4 when a filter produces NO output, which is the legitimate empty-comment-list case. Treating it as an error turned "no comments yet" into an input error — and callers fail closed on those, so a new PR would have read as unclassifiable. Exit 4 is now accepted. 44 classifier tests, 155 total. `~~~` and the boundary fixes are each mutation-verified; the out-of-band fix has no equivalent mutation (it is structural, not a regex) so its evidence is the direct reproduction against the previous commit. refs #629 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Decisions-Edit: yes	2026-07-26 00:47:40 +02:00
timothyandClaude Opus 5	0f83b54334	fix(629): close three false-opens in the H10 verdict grammar, and give it tests ... The H10 classification lived inline in `pretooluse-merge-consent.sh` with no tests. Three protections the `release.review-verdict-gate` record described were never actually implemented, and each graded an unreviewed head as approved. All three reproduced first: 1 MERGEABLE-LATER -> positive the token was prefix-matched, so any word STARTING with mergeable/approved/lgtm passed 2 fenced code block -> positive the line-start anchor is satisfied inside ```, so documentation showing the convention was a verdict 3 URL-borne sha -> positive the sha came from the first `@<hex>` ANYWHERE on the line, so a markdown link could supply it Fixes: whole-word token matching, with a token in neither vocabulary classified `unknown` (never positive, and not guessed into a block either — it goes to a human); fenced blocks stripped with fence state reset per comment body; the sha read from the verdict's OWN `@ <sha>` field, which also makes multi-`@` lines unambiguous. The grammar moves to `scripts/check-review-verdict.sh` so it can be tested at all — 38 tests, and each fix mutation-verified: restoring the old regex/extraction makes exactly the corresponding test fail, control green. #629's fourth reported item is NOT a defect and is not claimed as a fix. A later `@ <head>` on a BLOCKED line was reported as "masking a negative"; under the documented grammar that line is a verdict for the sha in its own field, so `stale` is correct — and was correct before this change too. Kept as a characterization test. `test_post_review_verdict.py`'s cross-check re-implemented the hook's regexes in Python and asserted the shell still contained them. That mirror is removed: it is the same duplication that let these three survive, and a Python copy would keep passing while the shell drifted. It now runs the real classifier. The decision record is corrected — it asserted the URL protection this commit actually adds. Note: the active corpus is 5637 lines against a 5600 budget, so the validator emits its consolidation warning (non-blocking). That is #620's subject, not regressed here. fixes #629 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Decisions-Edit: yes	2026-07-26 00:47:40 +02:00
timothy	fba5233caf	feat(610): split the decision corpus into one YAML-frontmatter file per record ... 168 records -> docs/decisions/records/<area>/<topic>.md (163 active, 23 dirs) and docs/decisions/archive/<area>/<topic>.md (5 archived). The filename IS the key, so one-active-record-per-key becomes a filesystem property rather than a validator check, and supersession becomes a `git mv`. WHY: the monolith was a concurrency problem before an aesthetic one. A 3,900-line append target made parallel sessions collide -- PR #605 and PR #614 both hit append-vs-append conflicts during routine rebases, and hand-resolving those inside the corpus is exactly the operation the rationale-rewrite guard exists to police. HOW IT IS VERIFIED: a ~170-file diff cannot be meaningfully read, so correctness does not rest on reading it. The parser was taught BOTH formats first, so the body-diff guard parses the old form at the merge-base and the new form at head -- the migration validates itself, no bypass. The proof is a field-level equivalence harness: 168 records before and after, zero lost, zero gained, zero field mismatches, zero rationale bodies differing. Reviewers should scrutinise the harness; it is the actual evidence. What measuring caught that reading would not have: - ~500 lines sit OUTSIDE any record -- decisions.md's lifecycle schema and each topic file's preamble, mostly the only copy. Source files are kept and stripped, never deleted. They also cannot be filed per-area: topic files hold several areas and 4 of 23 areas span several files. - Archive discovery was a non-recursive glob; after the split it found ZERO archived records, surfacing as four bogus "supersedes points to unknown key" errors rather than an obvious failure. - ~32 live docs point into the corpus BY DATE, which the split dangles. Each stripped file now ends with a generated "Records formerly in this file" index, which also rescues the identical breadcrumbs in old issue comments. - decisions.md's "In this file:" list was 97 same-file anchor bullets that the split makes WRONG, not merely stale. Dropped; the generated index replaces them with links that resolve. The equivalence harness now runs against a checked-in FIXTURE, not the live corpus. The earlier version migrated the real tree, which made it a one-shot: the moment the migration landed there was nothing left to move and the tests failed for reasons unrelated to the code. A fixture keeps them testing the SCRIPT rather than the repo's current state. Keys preserved verbatim, warts included: `sched` (12) and `scheduling` (1) remain two directories for one concept. Renaming a key is not a move -- it changes identity, breaks the equivalence proof, and invalidates MemPalace's per-key drawers. Taxonomy normalisation is separate work. refs #610	2026-07-25 19:45:09 +02:00
