Fixes the three findings issue #1010 grouped as "lower priority than data integrity, but confirmed real and cheap to fix":

  1. Nested-bracket link-label regex gap (PR Declare the Repository Description in registry/repos.json (#639) #913): spec/validate.py's and spec/audit.py's [^\]]*-based link regexes stopped at the first ], so [API [docs]](url) passed both the registry description gate and strip_md_links() undetected. Replaced with a balanced bracket/paren scanner in both files.
  2. README PATH-persistence self-contradiction (PR Fix Promotion-PR Review Findings on Pre-Commit Hooks Rollout #964): the pre-commit snippet's README claimed uv tool install gives an unconditionally PATH-available command, contradicting the next sentence's own conditional-PATH guidance. Applied CodeRabbit's proposed wording.
  3. Quota-widening-only-when-empty gap (PR Widen the Copilot Bot ID Lookback Past a Long Outage #986): copilot_history() only widened past HISTORY_PRS when the narrow window came back fully empty, so a narrow window carrying only a Copilot comment (no formal review) returned early with no usable bot id, leaving a review just outside the window permanently unread. Widening is now keyed on whether a usable bot id was found, not on emptiness.

Each fix carries a regression test. Full suite (849 tests), ruff format/check, mypy, prose_lint, and repo_gate (eol/eol-coverage) all pass.

Closes #1010.

`[^\]]*`-based regexes in spec/validate.py and spec/audit.py stopped at
the first `]`, so a link label carrying its own nested brackets
(`[API [docs]](url)`) passed both the registry description gate and
strip_md_links() undetected. Replaced with a balanced bracket/paren
scanner in both files, kept in sync as before.

Fixes one of the three findings tracked in #1010.
The snippet's README claimed uv tool install gives an unconditionally
PATH-available command, contradicting the very next sentence, which
already treats PATH availability as conditional on uv's tool bin
directory. Claim only persistence here.

Fixes one of the three findings tracked in #1010.
copilot_history() only widened past HISTORY_PRS when the narrow window
came back fully empty. A narrow window carrying only a Copilot comment,
no formal review, returned early instead, leaving copilot_bot_id() with
nothing to read since only the review connection carries the id. A
formal review just outside the narrow window went permanently unread.
Widening is now keyed on copilot_bot_id(entries) rather than emptiness.

Fixes one of the three findings tracked in #1010.

📝 Walkthrough

Walkthrough

The change adds balanced Markdown link parsing, widens Copilot history lookup for comment-only results, adds regression and performance tests, and updates pre-commit installation guidance.

Changes

Balanced Markdown link validation

Layer / File(s) Summary
Balanced Markdown parsing and validation
spec/validate.py, spec/audit.py, scripts/tests/test_spec_validate.py
Balanced parsing recognizes nested and escaped link delimiters. Validation and stripping use the new parser. Tests cover nested links, escaped brackets, and unmatched-bracket performance.

Copilot history fallback

Layer / File(s) Summary
Widened Copilot history lookup
scripts/pr_review.py, scripts/tests/test_pr_review.py
copilot_history widens the search when narrow results contain no usable review bot ID. Regression coverage verifies comment-only narrow results.

Pre-commit installation guidance

Layer / File(s) Summary
Installation and hook execution documentation
catalog/snippets/pre-commit/README.md
The README clarifies persistent uv tool install commands and independent uvx hook execution.

High-Level Assessment

The following are alternative approaches to this PR:

1. Shared Markdown utility
  • ➕ Eliminates duplicated balanced-scanner logic.
  • ➕ Prevents validator and auditor behavior from drifting.
  • ➖ Couples independently executed specification tools.
  • ➖ May complicate standalone distribution or import paths.
2. Markdown parser dependency
  • ➕ Handles a broader range of Markdown syntax and escaping.
  • ➕ Avoids maintaining custom parsing rules.
  • ➖ Adds dependency and startup overhead for a narrow validation need.
  • ➖ Parser output may not match the repository's intentionally limited link grammar.

Recommendation: Keep the dependency-free balanced scanner for this focused fix because it directly covers the supported inline and reference link forms. If these parsers evolve again, extract the duplicated scanner into a shared, dependency-free spec utility to prevent drift while preserving standalone execution.

Widen Copilot history when no bot ID is available

Action required

1. Nested links evade scanning ✓ Resolved 🐞 Bug ≡ Correctness
Description
After a balanced bracket run is not itself followed by a destination, both scanners jump past the
whole run, so [[docs](url)] skips the valid inner [docs](url). description_errors() therefore
accepts a description containing a Markdown link, while strip_md_links() leaves the same link
unchanged.

Direct nested-input correctness gap in new scanner, matching recently accepted parser regression
fixes.

PR-#1004

ⓘ Recommendations generated based on similar findings in past PRs

Evidence
At the outer [ in [[docs](url)], _bracket_span returns the position after the final ];
neither following-link check succeeds, and line 97 jumps directly to that position, never inspecting
the inner [. The audit copy makes the same jump, and the cited callers use these scanner results
directly for rejection and link stripping.

## Issue description
The balanced scanners skip nested link candidates when an outer bracket run is not itself a link. For example, `[[docs](url)]` must still detect and strip the inner link.

## Issue Context
Advance only one character after a balanced label candidate fails both inline and reference-link checks; keep the full-span jump after a successful match. Apply equivalent behavior in both duplicated scanners and add regression coverage for validation and stripping.

2. Escaped labels strip incorrectly ✓ Resolved 🐞 Bug ≡ Correctness
Description
_bracket_span() counts backslash-escaped [ characters as nesting, so a valid link such as `[API
\[docs](url)` fails as an outer span and is instead stripped from the escaped inner bracket.
strip_md_links() consequently produces [API \docs rather than the link label API \[docs,
causing false README-description mismatch results.

spec/audit.py[R640-643]

ⓘ Recommendations generated based on similar findings in past PRs

Evidence
The new loop increments depth for every opening delimiter without checking whether it is escaped.
When the outer span never balances, markdown_link_spans() resumes at later characters and can
treat the escaped inner [ as a new link opener; strip_md_links() then preserves the prefix and
substitutes only that incorrect inner span.

## Issue description
The new bracket-depth scanner treats escaped delimiters as structural delimiters, corrupting link-label extraction for labels containing escaped brackets.

Code

Comment thread spec/audit.py
The balanced-bracket scanner had two correctness gaps of its own,
introduced by the same rewrite that fixed the nested-label regex gap:

On a span that matched brackets but was not itself followed by a
destination or reference, both scanners jumped to the end of the whole
span instead of retrying one character in, so a link nested inside a
non-link bracket run, e.g. [[docs](url)], was skipped entirely.

The bracket-matching stack counted a backslash-escaped delimiter
(\[, \], \(, \)) as real nesting, corrupting the label of a link
whose text legitimately contains an escaped bracket.

Both fixed in both files, with regression tests in each.
