ADR-1703 Phase 7 / epic #1702 closeout. The mechanical teardown is already
complete across phases 1-6 (regex scanner retired P3, ratchet deleted P4,
allowlist portability-usage gone, windows-portability-ok comments swept,
every DEFECT.WINDOWS-* predicate rewritten per-phase). This phase delivers the
two remaining ADR-mandated closeout items:
- docs/contributing/adding-a-portability-rule.md: the forward architecture
recipe (Diátaxis Explanation) — the five seams (rule / portability-vocab /
platform-guard / disable-ban / ci-test-scope), the zero-escape-hatch contract,
the shipped-rule catalog, and the step-by-step checklist for adding a new
local/* portability rule.
- docs/adr/1703: Status Proposed -> Accepted (all seven phases shipped); a
Phase 7 as-built note recording the two deviations from the Phase 0 catalog —
Phase 6's rename-only scope decision (#1740) and the codex-review precision
tightening on require-fs-op-fallback.
- docs/contributing/cross-platform-portability-rules.md: cross-link to the new
guide from the rule reference.
No code, no test, no runtime change. Epic #1702 Phase 6 box checked; Phase 7
box + epic closure to follow at PR merge.
Closes#1744

* feat(#1740): require-fs-op-fallback production AST rule + Windows transient-lock retry (Phase 6)
ADR-1703 Phase 6 of the cross-platform portability epic (#1702). Adds the
second production-code portability AST rule + the ADR-mandated glob expansion
to bin/install.js and scripts/build-hooks.js.
- eslint-rules/require-fs-op-fallback.cjs: flags an unguarded fs.rename /
fs.renameSync (the atomic-publish primitive named first in
DEFECT.WINDOWS-FS-OPS.symptom) that is NOT inside a try/catch whose handler
references a transient errno ('EPERM'/'EBUSY'/'EACCES' or a *RETRY_ERRNOS
set) AND NOT behind a Windows platform guard. A catch that silently swallows
or cleans-up-and-rethrows without an errno check does NOT satisfy the
defect's 'never silently swallow' clause. copyFile/unlink are deliberately
not flagged (they are the fallback primitives per the defect's own
fix-forward). Scope narrowed to rename per Phase 5's precision discipline;
documented on #1740.
- src/shell-command-projection.cts: export retryRenameSync(from, to) — the
drop-in bounded-retry helper over the existing atomicRenameWithRetry.
- 27 bare fs.renameSync sites across 11 modules routed through retryRenameSync
(capability-lifecycle/lock/source, installer-migrations, milestone, phase,
planning-workspace, roadmap-upgrade, runtime-hooks-surface, state,
workstream). Idempotent on POSIX; resilient to AV/indexer transient locks
on Windows.
- eslint.config.mjs: register rule at error on src/**/*.cts; new focused
portability-rules block covering bin/install.js + scripts/build-hooks.js
(ADR-1703 L124-126 glob expansion — both files are compliant: zero
rename violations).
- tests: 15-case RuleTester suite; portability-rule-disable-ban extended
(PROTECTED_RULES + scans bin/install.js/build-hooks.js with shebang
handling); ci-test-scope portability-lint selection rule.
- CONTEXT.md DEFECT.WINDOWS-FS-OPS predicate rewritten to point at the rule;
docs/contributing/cross-platform-portability-rules.md reference + how-to.
Closes#1740
* chore(#1740): backfill changeset pr:1742
* fix(#1740): tighten require-fs-op-fallback precision (codex review HIGH-1/HIGH-2)
Addresses two false-negative findings from the codex (gpt-5.5/high)
adversarial review of PR #1742:
HIGH-1 — a catch that REFERENCES a transient errno but only rethrows (no
retry/fallback) was marked compliant. The DEFECT.WINDOWS-FS-OPS fix-forward
requires retry, not just recognition. Fix: catchHandlerHasRetrySignal now
requires a loop `continue` backedge OR a `return <call>` delegation; a bare
rethrow is flagged. The misleading `/* retry logic */` valid test is replaced
with a real retry loop, and the rethrow-only shape is added as invalid.
HIGH-2 — the nested-try ancestor walk treated an OUTER errno-catch as
protecting the rename even when an INNER catch intercepted/swallowed the error
(the outer catch is unreachable). Fix: isInsideTransientErrnoTryCatch now stops
at the NEAREST enclosing TryStatement WITH A CATCH HANDLER whose block contains
the rename (try-finally is skipped — it doesn't catch); outer catches are no
longer consulted. The unsound nested-try valid test is converted to invalid,
and a try-finally-skipped valid case is added.
Verified: 17 RuleTester cases pass; zero new production violations (the 27
fixed sites use retryRenameSync; the real retry loops — atomicRenameWithRetry,
capability-ledger/consent, build-hooks — remain compliant via continue/errno);
lint:ci green; disable-ban + vocab-drift green.

* feat(#1733): normalize-path-in-content production AST rule (Phase 5)
ADR-1703 Phase 5 — the first production-code rule. local/normalize-path-in-content
(src/**/*.cts, @typescript-eslint/parser): flags a path-returning fn result
(path.basename excluded — returns a separator-less filename) interpolated into an
@-reference / config-dir markdown body without .replace(/\\/g,'/') normalization,
per RULESET.CONTENT-PATH-NORMALIZATION / DEFECT.WINDOWS-PATH-LEAK-IN-MARKDOWN-CONTENT.
Build-and-assess found the canonical defect site (computePathPrefix) already
compliant and only 1 src/ hit — a false positive (path.basename in a status
message) — eliminated by narrowing (exclude basename; require a real @-ref/
config-dir marker, not bare .md). 0 src/ violations: clean forward-prevention.
The out-of-band disable-ban now scans src/**/*.cts too (typescript-estree) so the
production rule also cannot be eslint-disabled. Registered (error) + PROTECTED_RULES;
CONTEXT.md predicates + how-to doc updated.
- RuleTester suite (26 cases)

* docs(#1733): add changeset for Windows agent-skills path-leak fix
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
* fix: harden mutation-matrix.cjs stdin read against EAGAIN on non-blocking pipe
scripts/mutation-matrix.cjs read piped stdin via readFileSync(process.stdin.fd).
On macOS libuv marks the stdin pipe fd non-blocking, so a synchronous read can
throw EAGAIN before the writer fills the pipe — intermittently, under heavy CI
shard load — aborting the script (status 2) and flaking mutation-matrix-ratchet.
Replace with readStdinSync(): an fs.readSync loop that retries on EAGAIN (1ms
synchronous Atomics.wait yield), stops on 0-byte/EOF, and rethrows other errors.
Deterministic regression test injects EAGAIN via an fs.readSync monkeypatch.

* ci: re-run golden-install-parity on src/lib + installer changes (close drift guard)
golden-install-parity hashes every installed bin/lib/*.cjs per runtime, so it
must re-run whenever the built lib could change. ci-test-scope selected it for
neither src/** nor installer changes, so a source-only edit (e.g. #1691's
milestone.cts/roadmap.cts) recompiled bin/lib and silently drifted the golden
fixtures past the scoped lane. Add golden-install-parity.test.cjs to both the
'TS runtime sources' and 'installer and package layout' selection rules, with
behavioral regression tests for each.
