BREAKING CHANGE: the {NNN} in CA-{SCANNER}-{NNN} identifies the check that
produced the finding. It used to be the finding's position in that scanner's
output for that run, which made it unstable across CONFIGURATIONS, not just
across releases as STATE framed it. Measured on two fixtures: "No custom
subagents" was CA-GAP-007 on minimal-project and CA-GAP-004 on healthy-project.
A user who fixed an unrelated earlier gap silently renumbered every later one,
so a .config-audit-ignore pin retargeted to a neighbouring finding with no
version change at all.
Second measured arm: README already documented the opposite scheme. It and the
scanner headers describe ~20 numbers as check codes (CA-SKL-003 = oversized
body, CA-PLH-015 = folder shadowing, CA-TOK-006 = schema deferral), and the
counter could only produce those in the all-fire case -- source-order positions
are 4, 3 and 8. The documentation described the scheme; the implementation was
what was wrong. Every published number is preserved by construction and pinned
exhaustively in tests/lib/finding-codes.test.mjs.
scanners/lib/finding-codes.mjs is the single authority. Every finding() call
passes a `code`; an undeclared or missing one THROWS. No counter fallback --
that would reproduce D1's findGapId -> 'unknown' silent degradation and let a
half-converted scanner ship IDs that look valid. findingCounter/resetCounter
are deleted outright, not left as no-ops. Retirement is now a mechanism:
RETIRED_CODES tombstones a withdrawn key so its number is never reissued,
seeded with GAP t3_8 -- the D1 removal that opened this chunk.
IDs are consequently NOT unique per finding: one check failing in three files
emits three findings sharing an ID. That inverts which consumer is correct, so
every f.id/findingId site was classified before the change. diff-engine and
most of fix-engine already keyed on scanner+title+file (drift was never lying);
fix-engine's verification did not, and keyed on the ID alone -- fixing one of
two sibling instances marked both fixed, and the untouched one, still present
in the re-scan, was reported as a REGRESSION. Red test first, then keyed on
(findingId, file), which both planFixes and applyFixes already carry.
plugin-health's crossIds Set was measured and is a clean negative: cross
findings are allFindings.slice(crossPluginStart) and codes 18/19 are emitted
only in that tail, so the partition holds by construction.
unknownSuppressions() reports a pin that names no declared check, in the
--output-file payload (ux-rules rule 2 -- a stderr-only warning is invisible to
the commands) and only when one exists, so a clean config is byte-identical.
That is what makes the break safe: a stale pin goes loud instead of dying quiet.
Frozen tests/snapshots/v5.0.0/ untouched on disk. IDs are masked out of that
comparison (mask-finding-ids.mjs) rather than re-derived -- re-deriving
positional IDs would assert the retired scheme against itself, and #58's
isGapEntry off-by-one is the measured example of that misfiring. The dead
re-derivation is removed from strip-retired-gap.mjs. default-output snapshots
re-approved after confirming the diff is IDs and nothing else.
Guards, each seen red against its own defect: a missing code (scanner errors
out mid-sweep), an orphan declaration, a resurrected retired key, and a
documented ID naming no check. The sweep asserts the union across all 16
scanners, never per scanner -- a per-scanner assertion goes green on a partial
conversion.
Fasit written before implementation: docs/mbug28-id-semantics-fasit.local.md,
including one correction made before running (CML has 12 checks over 13 call
sites -- the anchored and calibrated char-budget arms are one check, which a
repeated-title sweep found and my call-site count had missed).
Suite 1535 -> 1573, 0 failing.

The ? -> [^/] replacement ran AFTER the {{GLOBSTAR_SLASH}} placeholder was
restored to '(?:/.+/|/)', corrupting the group opener '(?:' into '([^/]:' —
every rule pattern containing a mid-pattern '/**/' silently matched only the
zero-dir branch and live rules were flagged 'matches no files' (CA-RUL).
Found by dogfooding /config-audit implement on a throwaway repo copy: the
implementer agent's correct 'posts/**/post.md' rule was flagged dead.
Fix: run the ? replacement before placeholder restoration. Fixture outcomes
byte-identical; frozen v5.0.0 baselines untouched.

A rule's paths:/globs: pattern scopes relative to the directory containing
the rule's .claude/, not the outer scan target. countGlobMatches globbed
against the scan root and collectProjectFiles' depth>4 cutoff never reached
deep matching files, so a live rule in a nested repo (e.g. a marketplace
checkout under ~/.claude) was wrongly flagged "matches no files / never
activates" (high) — a false F-grade for any user with rules in a nested repo.
Same scope-conflation family as M-BUG-1/2/8.
- deriveProjectRoot(ruleAbsPath): parent of the rule's .claude segment.
- collect + glob per project root (cached), relative to that root — so a
nested repo's rule resolves against its own tree, where its files live.
- user-global rules (root === HOME) skip the no-match check: they scope
against whatever project is active at runtime, not a fixed tree, so
"matches 0 files here" is not a dead-rule signal (and avoids a HOME walk).
TDD: 2 failing tests (nested-repo false-positive + HOME guard) -> green.
Full suite 1307/0; frozen v5.0.0 + default-output snapshots unchanged (RUL
appears in none; the fix is a no-op when projectRoot === targetPath, i.e. the
common single-repo scan). Dogfooding C6: clears the 2 ktg-privat false
positives on the real machine and surfaces a previously-hidden genuine dead
rule (false negative) in the bundled optimal-setup example.

Per the official "what survives compaction" model (context-window.md):
only the project-root CLAUDE.md (+ unscoped rules) is re-injected after a
context compaction. Two additive, structural findings (low severity):
- RUL: a large (>50-line) PATH-SCOPED rule — reloads only on a matching
file read, and is not re-injected after compaction, so must-hold rules
can silently drop mid-session.
- CML: a NESTED (subdirectory) CLAUDE.md — not re-injected after
compaction (only the project root is).
Additive (no new scanner, count stays 13); one humanizer entry each;
hermetic temp-fixture tests (positive + negative). Suite 957 -> 961,
SC-5 byte-stable, self-audit A/A.
Known limitation (pre-existing, broader than A): the lightweight
frontmatter parser reads inline `paths:` but not YAML block sequences,
so block-sequence-scoped rules are still seen as unscoped. Deferred.
Part of v5.5.0 "steering-model I". Foundation (active-config-reader
enumeration) deferred to v5.6 with B.

HKV: add Setup, UserPromptExpansion, PostToolBatch to VALID_EVENTS,
verified live against code.claude.com/docs/en/hooks.md (2026-06-19). A
valid hook using one of these was wrongly flagged "will never fire" — a
user could delete a working hook. Made the "(N total)" hint dynamic so
it can't drift again. Flagged the unverified kebab 'post-session' in a
comment (an existing test depends on it; follow-up check needed).
RUL: reword the globs finding. Only `paths:` is documented; whether CC
ever read `globs` is unverified, so the old "deprecated/legacy" framing
overclaimed (Verifiseringsplikt). New wording steers to the documented
`paths:` field. Updated the coupled fix-engine title match and the
humanizer entry (which also carried the "field was renamed" overclaim).
Suite 950 -> 954 (badge bumped). self-audit A/A, scanner count 13. No
version bump — these land in the pending v5.4.1 patch.

Add /ultraresearch-local for structured research combining local codebase
analysis with external knowledge via parallel agent swarms. Produces research
briefs with triangulation, confidence ratings, and source quality assessment.
New command: /ultraresearch-local with modes --quick, --local, --external, --fg.
New agents: research-orchestrator (opus), docs-researcher, community-researcher,
security-researcher, contrarian-researcher, gemini-bridge (all sonnet).
New template: research-brief-template.md.
Integration: --research flag in /ultraplan-local accepts pre-built research
briefs (up to 3), enriches the interview and exploration phases. Planning
orchestrator cross-references brief findings during synthesis.
Design principle: Context Engineering — right information to right agent at
right time. Research briefs are structured artifacts in the pipeline:
ultraresearch → brief → ultraplan --research → plan → ultraexecute.
