@@ -2352,8 +2352,10 @@
 - **Section T — the citation rule** (`[0.4.82]`, queue item (26); 24 assertions): a citation of an **existing** heading → exit 0 with `citations_seen`/`citations_in_series` counted, `citations_missing == []`, `series == ['7.1']`; **the defect** → exit 1 with `FAIL PLAN.md:2 [changelog]`, the message `cites [7.1.5] but CHANGELOG.md has no such heading`, `citations_missing == [{'path','line','version'}]`, `lang: changelog` (so `promote`'s `_lint_failure_verdict` keeps rendering it as *a rule, not a parse*), `ok`/`exit_code` flipped, and a human summary ending `citation(s) checked, 1 missing`; **blob basis** (claim committed, worktree fixed → still 1; after the fix commit → 0); **the fence** → a `[9.9.4]` token is *counted* (`seen 4`) but *not judged* (`in_series 3`, `missing []`, exit 0) with the human line `… 4 citation(s) checked, 0 missing`; **no `CHANGELOG.md`** → `seen 2, in_series 0, missing [], series []`, exit 0, no failure and no error (tokens read, nothing judged); **the contract** → the rule appears in the docstring block *and* in what `--help` renders (derived, byte-for-byte) together with the `SCOPE` sentence; **cleanup** → the section leaves the sandbox green so a later mutant's clean-run assertion cannot fail for its own reason. Fixtures use series **`7.1`** and write the missing token into a *fixture file*, never into this suite — a literal in-series version committed here would be a citation in the REAL tree and the rule would fail the repo that hosts its own test (that constraint is documented in the tool's `SCOPE` paragraph too).
 - **Section U — the human closing line** (`[0.4.83]`, queue item (29); 20 assertions): **U1** a missing citation → exit 1 with `result: 1 file(s) fail lint (changelog) (exit 1)` and **no** `fail to parse` anywhere in the output, `json_exit_code` mirroring the process and the failure's `lang` shown to be the field the line is derived from; **U2** a broken PHP file → `result: 1 file(s) fail to parse or compile (exit 1)` with **no** `fail lint (`, i.e. the specific diagnosis does not regress to vagueness; **U3** both at once → `result: 2 file(s) fail lint (changelog, php) (exit 1)` (sorted, de-duplicated, both kinds named); **U4** `_SYNTAX_LANGS` in `tools/repo-lint` and in `tools/promote-dev-to-prod` are **the same set**, extracted by regex from both files rather than imported (a child must not import its parent, and prose agreement is what drifted in `[0.4.53]`); **U5** the function is defined exactly once and `main()` prints it exactly once (no hand-rolled second literal — P/Q's shape applied to a runtime line); **U6** the section leaves the sandbox green so a later mutant's clean-run assertion cannot fail for its own reason; **U7** (`[0.4.85]`, queue item (31)) — U4 compares two *declarations* to each other and never asks whether either covers what the tool **emits**, so `u7_classify <path>` derives four sets from that file's own source (the `EXT_LANG` and `SHEBANG_LANG` dict values, the `_SYNTAX_LANGS` frozenset, every literal `"lang": "…"` the gates hand to `failures[]`) and asserts three things: **U7-1** it read four non-empty sets (an extraction that reads nothing would pass every subtraction below vacuously — the same "cannot verify is not a pass" discipline the tool itself has), **U7-2** every dispatch lang is classified as syntax, **U7-3** every emittable lang is syntax **or one of a DECLARED rule set** (`RULE_LANGS = {"changelog"}` — declared rather than derived as `gate − syntax`, which would absorb a new rule automatically and make the check tautological), **U7-4** `rules_match=YES`, that declaration compared back against the gate in **both** directions so it may not drift either. The same function runs against `$TOOL` and, in M23, against a copy carrying one extra `EXT_LANG` entry.
 - **Section V — the NUMBER in the closing line counts files** (`[0.4.84]`, queue item (30); 14 assertions): U's two branches are both **one-failure** fixtures, so every assertion in U is satisfied by a counter that never counted files at all — V supplies the case where the two counts disagree. **V1** three `## [7.1.1]` headings → **two `FAIL CHANGELOG.md:` lines** with `result: 1 file(s) fail lint (changelog) (exit 1)` and **no** `result: 2 file(s)` anywhere (the defect, reproduced in the harness rather than quoted from a run); **V2** the same run in JSON, `len(failures) == 2` and `len({f['path'] …}) == 1`, both paths `CHANGELOG.md` — the two figures the sentence must *choose* between, asserted to differ so the fix cannot be "right" by coincidence; **V3** the opposite direction, two distinct broken PHP files → still `result: 2 file(s) fail to parse or compile (exit 1)`, so a fix that collapsed the number to 1 is caught too; **V4** the source shape, three counts (the derivation occurs once, both branch strings are fed `{n_files}`, `{len(failures)} file(s) fail` occurs zero times) — a later edit cannot silently hand the label a failure count again; **V5** the sandbox left green. `kinds` is deliberately **not** de-duplicated per file: one file tripping two rules must still be told both, so the noun decides the number while the list stays per failure.
 - **Section W — a lang with no linter wired is "cannot verify", never a crash** (`[0.4.86]`, queue item (33); 25 assertions): three independent tables decide what a committed file means — `EXT_LANG`, `SHEBANG_LANG` and `lint()`'s `cmd` dict (plus `LINE_RE`), so the first can grow an entry the second has never heard of. Measured before the fix (throwaway repo, one committed `app.ts`, each variant a copy of the tool with only the `.ts` entry added): **no cmd → `KeyError` at `cmd = {`, exit 1, stdout 0 bytes, traceback**; **no `LINE_RE` → `KeyError` at `LINE_RE[lang].search(msg)`, the same signature** — exit 1 is the code *defined* to carry `result: …` and it carried nothing, so a machine reader cannot tell "these files fail lint" from "the linter crashed". Both dispatches are `.get()` now, and the two failures are deliberately **not** treated alike: **no cmd → `errors[]` + exit 3** (`no linter wired for lang: <lang>`, since no check ran — and a silent `unsupported_ext`-style skip would render "nobody wired it" as "nothing to do"), **no line parser → `failures[]` with `line: null` + exit 1** (the linter *did* run and did say no; demoting a verified failure to exit 3 would hide a real breakage behind an environment problem). **W0** asserts the real tool cannot reproduce this at all (`.ts` is `unsupported_ext` there → exit 0), so the section's fixtures are the *future* edit: `w_build <out> <mode>` copies `$TOOL` and adds the `.ts` entry plus a `cmd` entry (`noline`/`wired`) and a `LINE_RE` entry (`wired`), each needle **counted** in an embedded python builder, with the cmd anchor accepting **both** spellings (`}.get(lang)` and the pre-step `}[lang]`) so a pre-fix replay fails on behaviour rather than on a build. **W2** (no cmd) = exit 3, empty stderr, no traceback, one `errors[]` entry naming `app.ts`/`typescript`, `failures == []`, the same **15-key** object any run emits, both human lines; **W3** (cmd, no parser) = exit 1, empty stderr, `line: null` with the message kept, `errors == []`, both human lines; **W4** is the over-correction guard (a wired `LINE_RE` still reports `line == 7`); **W5** pins the source shape (one `.get` per table, zero surviving subscripts, `--help` naming the new exit-3 cause — first draft reflowed because the phrase straddled a line break and W5's own needle could not match it); **W6** leaves the sandbox green. **No new mutant**: M23 already plants the unclassified `EXT_LANG` entry and catches it *analytically* because nothing runs that copy — W executes that copy now, so `M24` would re-plant what W2 runs; the index stays at **23**, and the suite's **header** (stopping at `M16` / `Section S`) is untouched, because extending a copy nothing checks is items (5)/(32) rather than their fix.
+- **Section X — a *mixed* run: `cannot verify` may not swallow the verified failure** (`[0.4.89]`, queue item (34); 17 assertions): M5's two fixtures are errors-only and failures-only, so the **middle** case — an unwired linter *and* a real `php -l` failure in the same run — was asserted nowhere, and there the closing line was built from `errors[]` alone: `result: cannot verify - 1 lint error(s) (exit 3)` printed directly under a `FAIL app.php:2 [php]` line it never mentioned, the last sentence a reader acts on naming only the half that is not a verdict. **X1** the fixture is a **copy** of the real tool (section W's `w_build … nocmd`, which adds the `.ts` `EXT_LANG` entry with no linter behind it — the real tool cannot produce this run at all), never `$TOOL`; **X2** the JSON never lied (`failures[0].path == 'app.php'`, `errors[0].path == 'app.ts'`, `exit_code 3`, `ok false`) and `exit_code 3` is asserted a second time as **M5 intact** — the wording fix must not move a verdict; **X3** THE defect: exit 3 preserved, stderr empty, the **LAST** line byte-exact at `result: cannot verify - 1 lint error(s), and 1 file(s) fail to parse or compile (exit 3)` with the `FAIL` and `ERROR` halves both present above it; **X4** the over-correction guard — fix the PHP file, keep the unwired linter, and the line must return to `result: cannot verify - 1 lint error(s) (exit 3)` **byte-identical to the pre-step form** (W2's own needle) with no `, and ` invented where there is no failure, because the clause is added by the presence of `failures` and by nothing else; **X5** the source shape — `def _failure_clause(failures) -> str:` defined exactly **once**, named exactly **three** times (1 definition + 2 callers) and the cannot-verify literal `result: cannot verify - {len(errors)} lint error(s){clause}` occurring exactly **once**, i.e. the fix had to be reached by *quoting* one derivation rather than by writing a second copy of the failure wording (the copy is what broke); **X6** the sandbox left green. **V4's needle moved with it**: `grep -cF 'result: {n_files} file(s) fail'` → `grep -cF '{n_files} file(s) fail'`, still wanting **2**, because the `result: ` prefix is now added by whichever caller composes the line while the clause it quotes is shared — the invariant (two branches, both fed the distinct-path count) is unchanged and the needle was narrowed to the part that is still one thing.
+- **Pre-fix replay for `[0.4.89]`**: the new suite against `HEAD`'s tool blob swapped **in place** (old md5 `1cb2a12e2ff5fc22dca8aec7e15427ef` → new `08644e5482dd9d6272d7beafcb81579f`, restored and re-verified byte-identical; log `/tmp/opencode/prefix34/pre-fix.log`) → **411 passed / 6 failed**: **X3's last line**, **X5 ×3** (0 definitions, 0 callers, and the `…error(s){clause}` literal absent — the three assertions that say "one derivation, two quotations"), **X5's** third counted with them, and **M24's precondition** (the `clause = f", and …"` needle does not exist, so its other three assertions could not run — hence **411 counted pre-fix against 420 post-fix**: 420 − 6 − 3). Guards that passed pre-fix and thereby identify themselves: **X1**, all of **X2** (both halves were always in the JSON), **X4 ×3** (the errors-only line was already byte-identical — it is the line this step did *not* change, which is exactly why it is a guard), **X6**, **V4 ×3** after the needle moved, and all of sections A–W. **The backup for this swap was taken wrong and the record says so**: the capture command was `git show HEAD:tools/repo-lint > /tmp/opencode/prefix34/new-tool.bak`, which writes the **old** blob under a name meaning "new" — so the restore step `cp`'d the *pre-fix* file back over the three edits and `git status` showed only the test file still modified. It was caught by an md5 mismatch against `08644e54…` before anything was staged, the three edits were re-applied, and the reconstruction came out **byte-identical** (same md5), so the replay above still describes the file it names; `/tmp/opencode/prefix34/new-tool.bak` still holds the old blob despite its name, and the lesson is that a replay's restore path must be verified by hash *before* it is trusted, not after it fails.
 - **Pre-fix replay for `[0.4.86]`**: the new suite against `HEAD`'s tool blob swapped **in place** (old md5 `0df9317ebe19afafeafb4766e3f8c405` → new `1cb2a12e2ff5fc22dca8aec7e15427ef`, restored and re-verified byte-identical; log `/tmp/opencode/prefix33/pre-fix.log`) → **382 passed / 17 failed**, every red in section W: **W2 ×8** (exit 3 vs the crash's 1, stderr, traceback, three JSON assertions, both human lines), **W3 ×5** (stderr, two JSON, both human), **W5 ×4** (both `.get` counts, the two surviving subscripts, the `--help` clause). **382 + 17 = 399**; the 8 W assertions that passed pre-fix identify themselves as guards — **W0 ×2, W1, W3's exit code, W4's exit code, W6 ×2** — the middle two passing **coincidentally**, because the pre-step crash also exited 1, which is exactly why no exit-code assertion could ever have caught this defect.
 - **Pre-fix replay for `[0.4.84]`**: the new suite against `HEAD`'s tool blob swapped **in place** (old md5 `16d7a0cc073ab416ff0d685ae666c481` → new `0df9317ebe19afafeafb4766e3f8c405`, restored and re-verified byte-identical; log `/tmp/opencode/pre-fix-replay-84.log`) → **357 passed / 6 failed**, every red a section-V finding or an unplantable precondition: **V1 ×2** (the `result: 1 file(s)` pin and its `result: 2 file(s)` twin), **V4 ×3** (the distinct-path derivation absent, both `{n_files}` branch strings absent, `{len(failures)} file(s) fail` present twice), **M22's precondition** (the needle does not exist — its other three assertions could not run, hence **357 counted pre-fix against 366 post-fix**: 366 − 6 − 3). Guards that passed pre-fix and thereby identify themselves: **V1's exit code and FAIL-line count**, **V2** (the JSON figures the line must choose between were already right — only the printed number was wrong), **V3** (the over-correction direction was already true before the fix, which is exactly why it is a guard and not a finding), **V5** and all of sections A–U unchanged. Captured **in place**, the way `[0.4.83]` learned to: a copy outside `tools/` makes section L report `repo_root: /tmp/…` and exit 3.
 - **No pre-fix replay for `[0.4.85]`, and the reason is the change**: that step edits **only** the suite — `git show HEAD:tools/repo-lint | md5sum` and `md5sum tools/repo-lint` both read `0df9317ebe19afafeafb4766e3f8c405` before it, so there is no "before" tool to swap in and a replay would be the baseline re-quoted. The red this step's assertions can produce is instead demonstrated **inside** the suite by M23, which is the same claim in a checkable form: the identical `u7_classify` call returns `dispatch_unclassified=NONE` for the tool and `dispatch_unclassified=typescript` for a copy carrying one unclassified `EXT_LANG` entry. The old suite against the untouched tool was measured at **366/0** immediately before the edit; the new suite on the same tree is **374/0**, i.e. exactly the eight assertions added and nothing moved.
 - **Pre-fix replay for `[0.4.83]`**: the new suite against `HEAD`'s tool blob swapped **in place** (new md5 `16d7a0cc073ab416ff0d685ae666c481`; old `0a5ccfcbbc9093212cce0c4d54d4d28c`, restored and re-verified byte-identical) → **333 passed / 9 failed**, every red a section-U finding or an unplantable precondition: **U1 ×2** (the rule line and its `fail to parse` twin), **U2**, **U3**, **U4** (no `_SYNTAX_LANGS` exists yet, so the set is unmatched), **U5 ×2** (0 definitions, 0 prints), **M20/M21 preconditions ×2** (the `if all(k in _SYNTAX_LANGS …)` needle does not exist — their other six assertions could not run, hence **342 counted pre-fix against 348 post-fix**). Guards that passed pre-fix and thereby identify themselves: **U1's exit codes**, **U2's exit code**, **U3's exit code** and all of sections A–T unchanged. Captured **in place**, not via `REPO_LINT_BIN` pointing outside `tools/`: the first attempt did exactly that and returned 11 extra reds in section L, because `default_repo()` resolves relative to the script — a harness artifact (`repo_root: /tmp/…`, exit 3) that cost one capture to read correctly, the same trap `[0.4.60]`'s replay documented.

 - **Section U — the human closing line** (`[0.4.83]`, queue item (29); 20 assertions): **U1** a missing citation → exit 1 with `result: 1 file(s) fail lint (changelog) (exit 1)` and **no** `fail to parse` anywhere in the output, `json_exit_code` mirroring the process and the failure's `lang` shown to be the field the line is derived from; **U2** a broken PHP file → `result: 1 file(s) fail to parse or compile (exit 1)` with **no** `fail lint (`, i.e. the specific diagnosis does not regress to vagueness; **U3** both at once → `result: 2 file(s) fail lint (changelog, php) (exit 1)` (sorted, de-duplicated, both kinds named); **U4** `_SYNTAX_LANGS` in `tools/repo-lint` and in `tools/promote-dev-to-prod` are **the same set**, extracted by regex from both files rather than imported (a child must not import its parent, and prose agreement is what drifted in `[0.4.53]`); **U5** the function is defined exactly once and `main()` prints it exactly once (no hand-rolled second literal — P/Q's shape applied to a runtime line); **U6** the section leaves the sandbox green so a later mutant's clean-run assertion cannot fail for its own reason; **U7** (`[0.4.85]`, queue item (31)) — U4 compares two *declarations* to each other and never asks whether either covers what the tool **emits**, so `u7_classify <path>` derives four sets from that file's own source (the `EXT_LANG` and `SHEBANG_LANG` dict values, the `_SYNTAX_LANGS` frozenset, every literal `"lang": "…"` the gates hand to `failures[]`) and asserts three things: **U7-1** it read four non-empty sets (an extraction that reads nothing would pass every subtraction below vacuously — the same "cannot verify is not a pass" discipline the tool itself has), **U7-2** every dispatch lang is classified as syntax, **U7-3** every emittable lang is syntax **or one of a DECLARED rule set** (`RULE_LANGS = {"changelog"}` — declared rather than derived as `gate − syntax`, which would absorb a new rule automatically and make the check tautological), **U7-4** `rules_match=YES`, that declaration compared back against the gate in **both** directions so it may not drift either. The same function runs against `$TOOL` and, in M23, against a copy carrying one extra `EXT_LANG` entry.
 - **Section V — the NUMBER in the closing line counts files** (`[0.4.84]`, queue item (30); 14 assertions): U's two branches are both **one-failure** fixtures, so every assertion in U is satisfied by a counter that never counted files at all — V supplies the case where the two counts disagree. **V1** three `## [7.1.1]` headings → **two `FAIL CHANGELOG.md:` lines** with `result: 1 file(s) fail lint (changelog) (exit 1)` and **no** `result: 2 file(s)` anywhere (the defect, reproduced in the harness rather than quoted from a run); **V2** the same run in JSON, `len(failures) == 2` and `len({f['path'] …}) == 1`, both paths `CHANGELOG.md` — the two figures the sentence must *choose* between, asserted to differ so the fix cannot be "right" by coincidence; **V3** the opposite direction, two distinct broken PHP files → still `result: 2 file(s) fail to parse or compile (exit 1)`, so a fix that collapsed the number to 1 is caught too; **V4** the source shape, three counts (the derivation occurs once, both branch strings are fed `{n_files}`, `{len(failures)} file(s) fail` occurs zero times) — a later edit cannot silently hand the label a failure count again; **V5** the sandbox left green. `kinds` is deliberately **not** de-duplicated per file: one file tripping two rules must still be told both, so the noun decides the number while the list stays per failure.
 - **Section W — a lang with no linter wired is "cannot verify", never a crash** (`[0.4.86]`, queue item (33); 25 assertions): three independent tables decide what a committed file means — `EXT_LANG`, `SHEBANG_LANG` and `lint()`'s `cmd` dict (plus `LINE_RE`), so the first can grow an entry the second has never heard of. Measured before the fix (throwaway repo, one committed `app.ts`, each variant a copy of the tool with only the `.ts` entry added): **no cmd → `KeyError` at `cmd = {`, exit 1, stdout 0 bytes, traceback**; **no `LINE_RE` → `KeyError` at `LINE_RE[lang].search(msg)`, the same signature** — exit 1 is the code *defined* to carry `result: …` and it carried nothing, so a machine reader cannot tell "these files fail lint" from "the linter crashed". Both dispatches are `.get()` now, and the two failures are deliberately **not** treated alike: **no cmd → `errors[]` + exit 3** (`no linter wired for lang: <lang>`, since no check ran — and a silent `unsupported_ext`-style skip would render "nobody wired it" as "nothing to do"), **no line parser → `failures[]` with `line: null` + exit 1** (the linter *did* run and did say no; demoting a verified failure to exit 3 would hide a real breakage behind an environment problem). **W0** asserts the real tool cannot reproduce this at all (`.ts` is `unsupported_ext` there → exit 0), so the section's fixtures are the *future* edit: `w_build <out> <mode>` copies `$TOOL` and adds the `.ts` entry plus a `cmd` entry (`noline`/`wired`) and a `LINE_RE` entry (`wired`), each needle **counted** in an embedded python builder, with the cmd anchor accepting **both** spellings (`}.get(lang)` and the pre-step `}[lang]`) so a pre-fix replay fails on behaviour rather than on a build. **W2** (no cmd) = exit 3, empty stderr, no traceback, one `errors[]` entry naming `app.ts`/`typescript`, `failures == []`, the same **15-key** object any run emits, both human lines; **W3** (cmd, no parser) = exit 1, empty stderr, `line: null` with the message kept, `errors == []`, both human lines; **W4** is the over-correction guard (a wired `LINE_RE` still reports `line == 7`); **W5** pins the source shape (one `.get` per table, zero surviving subscripts, `--help` naming the new exit-3 cause — first draft reflowed because the phrase straddled a line break and W5's own needle could not match it); **W6** leaves the sandbox green. **No new mutant**: M23 already plants the unclassified `EXT_LANG` entry and catches it *analytically* because nothing runs that copy — W executes that copy now, so `M24` would re-plant what W2 runs; the index stays at **23**, and the suite's **header** (stopping at `M16` / `Section S`) is untouched, because extending a copy nothing checks is items (5)/(32) rather than their fix.
 - **Section X — a *mixed* run: `cannot verify` may not swallow the verified failure** (`[0.4.89]`, queue item (34); 17 assertions): M5's two fixtures are errors-only and failures-only, so the **middle** case — an unwired linter *and* a real `php -l` failure in the same run — was asserted nowhere, and there the closing line was built from `errors[]` alone: `result: cannot verify - 1 lint error(s) (exit 3)` printed directly under a `FAIL app.php:2 [php]` line it never mentioned, the last sentence a reader acts on naming only the half that is not a verdict. **X1** the fixture is a **copy** of the real tool (section W's `w_build … nocmd`, which adds the `.ts` `EXT_LANG` entry with no linter behind it — the real tool cannot produce this run at all), never `$TOOL`; **X2** the JSON never lied (`failures[0].path == 'app.php'`, `errors[0].path == 'app.ts'`, `exit_code 3`, `ok false`) and `exit_code 3` is asserted a second time as **M5 intact** — the wording fix must not move a verdict; **X3** THE defect: exit 3 preserved, stderr empty, the **LAST** line byte-exact at `result: cannot verify - 1 lint error(s), and 1 file(s) fail to parse or compile (exit 3)` with the `FAIL` and `ERROR` halves both present above it; **X4** the over-correction guard — fix the PHP file, keep the unwired linter, and the line must return to `result: cannot verify - 1 lint error(s) (exit 3)` **byte-identical to the pre-step form** (W2's own needle) with no `, and ` invented where there is no failure, because the clause is added by the presence of `failures` and by nothing else; **X5** the source shape — `def _failure_clause(failures) -> str:` defined exactly **once**, named exactly **three** times (1 definition + 2 callers) and the cannot-verify literal `result: cannot verify - {len(errors)} lint error(s){clause}` occurring exactly **once**, i.e. the fix had to be reached by *quoting* one derivation rather than by writing a second copy of the failure wording (the copy is what broke); **X6** the sandbox left green. **V4's needle moved with it**: `grep -cF 'result: {n_files} file(s) fail'` → `grep -cF '{n_files} file(s) fail'`, still wanting **2**, because the `result: ` prefix is now added by whichever caller composes the line while the clause it quotes is shared — the invariant (two branches, both fed the distinct-path count) is unchanged and the needle was narrowed to the part that is still one thing.
-- **Pre-fix replay for `[0.4.89]`**: the new suite against `HEAD`'s tool blob swapped **in place** (old md5 `1cb2a12e2ff5fc22dca8aec7e15427ef` → new `08644e5482dd9d6272d7beafcb81579f`, restored and re-verified byte-identical; log `/tmp/opencode/prefix34/pre-fix.log`) → **411 passed / 6 failed**: **X3's last line**, **X5 ×3** (0 definitions, 0 callers, and the `…error(s){clause}` literal absent — the three assertions that say "one derivation, two quotations"), **X5's** third counted with them, and **M24's precondition** (the `clause = f", and …"` needle does not exist, so its other three assertions could not run — hence **411 counted pre-fix against 420 post-fix**: 420 − 6 − 3). Guards that passed pre-fix and thereby identify themselves: **X1**, all of **X2** (both halves were always in the JSON), **X4 ×3** (the errors-only line was already byte-identical — it is the line this step did *not* change, which is exactly why it is a guard), **X6**, **V4 ×3** after the needle moved, and all of sections A–W. **The backup for this swap was taken wrong and the record says so**: the capture command was `git show HEAD:tools/repo-lint > /tmp/opencode/prefix34/new-tool.bak`, which writes the **old** blob under a name meaning "new" — so the restore step `cp`'d the *pre-fix* file back over the three edits and `git status` showed only the test file still modified. It was caught by an md5 mismatch against `08644e54…` before anything was staged, the three edits were re-applied, and the reconstruction came out **byte-identical** (same md5), so the replay above still describes the file it names; `/tmp/opencode/prefix34/new-tool.bak` still holds the old blob despite its name, and the lesson is that a replay's restore path must be verified by hash *before* it is trusted, not after it fails.

 - **Pre-fix replay for `[0.4.86]`**: the new suite against `HEAD`'s tool blob swapped **in place** (old md5 `0df9317ebe19afafeafb4766e3f8c405` → new `1cb2a12e2ff5fc22dca8aec7e15427ef`, restored and re-verified byte-identical; log `/tmp/opencode/prefix33/pre-fix.log`) → **382 passed / 17 failed**, every red in section W: **W2 ×8** (exit 3 vs the crash's 1, stderr, traceback, three JSON assertions, both human lines), **W3 ×5** (stderr, two JSON, both human), **W5 ×4** (both `.get` counts, the two surviving subscripts, the `--help` clause). **382 + 17 = 399**; the 8 W assertions that passed pre-fix identify themselves as guards — **W0 ×2, W1, W3's exit code, W4's exit code, W6 ×2** — the middle two passing **coincidentally**, because the pre-step crash also exited 1, which is exactly why no exit-code assertion could ever have caught this defect.
 - **Pre-fix replay for `[0.4.84]`**: the new suite against `HEAD`'s tool blob swapped **in place** (old md5 `16d7a0cc073ab416ff0d685ae666c481` → new `0df9317ebe19afafeafb4766e3f8c405`, restored and re-verified byte-identical; log `/tmp/opencode/pre-fix-replay-84.log`) → **357 passed / 6 failed**, every red a section-V finding or an unplantable precondition: **V1 ×2** (the `result: 1 file(s)` pin and its `result: 2 file(s)` twin), **V4 ×3** (the distinct-path derivation absent, both `{n_files}` branch strings absent, `{len(failures)} file(s) fail` present twice), **M22's precondition** (the needle does not exist — its other three assertions could not run, hence **357 counted pre-fix against 366 post-fix**: 366 − 6 − 3). Guards that passed pre-fix and thereby identify themselves: **V1's exit code and FAIL-line count**, **V2** (the JSON figures the line must choose between were already right — only the printed number was wrong), **V3** (the over-correction direction was already true before the fix, which is exactly why it is a guard and not a finding), **V5** and all of sections A–U unchanged. Captured **in place**, the way `[0.4.83]` learned to: a copy outside `tools/` makes section L report `repo_root: /tmp/…` and exit 3.
 - **No pre-fix replay for `[0.4.85]`, and the reason is the change**: that step edits **only** the suite — `git show HEAD:tools/repo-lint | md5sum` and `md5sum tools/repo-lint` both read `0df9317ebe19afafeafb4766e3f8c405` before it, so there is no "before" tool to swap in and a replay would be the baseline re-quoted. The red this step's assertions can produce is instead demonstrated **inside** the suite by M23, which is the same claim in a checkable form: the identical `u7_classify` call returns `dispatch_unclassified=NONE` for the tool and `dispatch_unclassified=typescript` for a copy carrying one unclassified `EXT_LANG` entry. The old suite against the untouched tool was measured at **366/0** immediately before the edit; the new suite on the same tree is **374/0**, i.e. exactly the eight assertions added and nothing moved.
 - **Pre-fix replay for `[0.4.83]`**: the new suite against `HEAD`'s tool blob swapped **in place** (new md5 `16d7a0cc073ab416ff0d685ae666c481`; old `0a5ccfcbbc9093212cce0c4d54d4d28c`, restored and re-verified byte-identical) → **333 passed / 9 failed**, every red a section-U finding or an unplantable precondition: **U1 ×2** (the rule line and its `fail to parse` twin), **U2**, **U3**, **U4** (no `_SYNTAX_LANGS` exists yet, so the set is unmatched), **U5 ×2** (0 definitions, 0 prints), **M20/M21 preconditions ×2** (the `if all(k in _SYNTAX_LANGS …)` needle does not exist — their other six assertions could not run, hence **342 counted pre-fix against 348 post-fix**). Guards that passed pre-fix and thereby identify themselves: **U1's exit codes**, **U2's exit code**, **U3's exit code** and all of sections A–T unchanged. Captured **in place**, not via `REPO_LINT_BIN` pointing outside `tools/`: the first attempt did exactly that and returned 11 extra reds in section L, because `default_repo()` resolves relative to the script — a harness artifact (`repo_root: /tmp/…`, exit 3) that cost one capture to read correctly, the same trap `[0.4.60]`'s replay documented.
