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RETIRED_CODES tombstones a withdrawn key so its number is never reissued,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.

CNF compared every discovered settings.json/hooks.json pairwise regardless of
origin, so it treated installed plugins' bundled configs — each plugin's own
settings.json/hooks.json plus its shipped test fixtures and examples under
~/.claude/plugins/ — as if they were the user's authored cascade. A "conflict"
between two plugins' bundled test fixtures is not something a user can resolve,
yet these dominated the count: 339 CNF findings on this machine (315 high-sev
permission allow/deny "conflicts", 18 duplicate-hook, 6 settings-key), almost all
sourced from plugin-internal fixtures. The Conflicts grade was F on pure noise.
Fix: CNF excludes any file whose path is under `.claude/plugins/` from conflict
analysis (new isPluginBundled predicate; absPath marker). Kept CNF-local rather
than a discovery-level skip on purpose: an active plugin's contributed
hooks.json/.mcp.json legitimately lives in plugins/cache and other scanners need
it — only conflict analysis must ignore plugin-bundled files. Same class as
M-BUG-8 (non-live config trees treated as live). Suite 1344/0 (+3: plugin-bundled
exclusion, discovery-side sanity, over-exclusion guard). Frozen v5.0.0 + SC-5
snapshots untouched (marketplace-medium has no plugins/ paths), no re-seed.
Dogfood ~/.claude CNF 339->0 (F-grade was 100% plugin-bundled noise; the ~3
genuine user-scope local settings have no actual conflicting keys, matching the
plan C5 "real surface ~3 files" prediction).
Follow-up (not in this fix): classifyScope tags plugin-bundled files by checking
basePath instead of the file's own path, so scope:'plugin' is effectively dead
for a ~/.claude-rooted scan. Fixing it would let every scanner trust the scope
field, but that is a discovery-layer change beyond this bug's scope.
The DIS scanner collapsed Tool(param) rules to the bare tool name, so
Agent(model:opus) deny + Agent(model:sonnet) allow (and the same for
WebFetch(domain:...)) were flagged as dead config — a false positive now
that CC 2.1.178 matches Tool(param:value) and 2.1.172 adds domain rules.
The conflict-detector shared the blind spot from the other side: a
wildcard deny like WebFetch(domain:*) did not cover a
WebFetch(domain:good.com) allow, so a genuine cross-scope conflict was
missed (false negative).
New shared scanners/lib/permission-rules.mjs:
- parseRule / paramMatches (glob)
- dominates(deny, allow) -> DIS dead-allow (deny fully covers allow)
- rulesIntersect(a, b) -> CNF cross-scope conflict (match sets intersect)
DIS now delegates to dominates; conflict-detector :156 delegates to
rulesIntersect. A bare deny still covers all params, so true positives
are preserved (Bash deny + Bash(npm:*) allow still flagged).
Re-seeded the marketplace-medium snapshots: the false-positive CA-DIS
finding (Read(src/**) allow + Read(./.env) deny) is correctly gone. This
changes snapshot CONTENT only — envelope schema is unchanged, so --json
and --raw stay byte-stable.
Full suite: 837/837 green (+25). self-audit PASS, A(100)/A(97).
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.
