CC 2.1.226's /doctor Check 8 covers auto mode with usage-weighted judgement.
The binding positioning forbids carrying a feature whose whole value is
duplicating a /doctor check, so the "adopt this feature" nudge goes. The
deterministic side stays: SET still validates autoMode structure and still
flags it as dead config in shared project settings. GAP dimensions 25 -> 24.
The title lived in FOUR tables, not the two the removal was scoped against:
the dimension list, scoring TITLE_TO_ID, the humanizer's static translations,
and the scoring denominators (TIER_COUNTS t3 8->7, TOTAL_DIMENSIONS 25->24,
MAX_WEIGHTED 42->41) -- the one that moves a user-visible number. findGapId
falls back to 'unknown' silently, so a partial removal would have degraded
without failing. A blanket sync invariant now asserts all four against
GAP_CHECKS instead of comparing occurrences pairwise; each arm was verified
red against its own defect (denominator drift, orphaned humanizer entry,
resurrected dimension).
Frozen tests/snapshots/v5.0.0/ stays untouched. strip-retired-gap.mjs is the
removal twin of strip-added-scanner.mjs: it strips the retired dimension from
whichever side still carries it and re-derives GAP IDs, since retiring a
dimension from mid-list shifts every later ID by one. Derived utilization
figures are dropped from comparison rather than recomputed -- recomputing them
in a test helper would assert the new arithmetic against itself, and
scoring.test.mjs already pins them exactly. Re-seeding was rejected: it would
silently bake in any other drift across every scanner those four files cover.
risk_score, risk_band, verdict, overallGrade, maturity and segment are
byte-identical across the change (severity info carries zero risk weight; GAP
is excluded from the overall grade). Utilization shifts 43 -> 44 on the fixture.
D2 (CA-SKL-002) is NOT removed. Verified against the primary source first: the
CC changelog carries exactly one budget-fraction statement (L3786, 2.1.32) and
nothing supersedes it, so our 2% is current and 002 is not a duplicate with a
stale figure. /doctor's ~1% could not be reconciled from the changelog and it
discloses its own numbers as disk estimates, so it is recorded, not adopted.
Left explicitly unverified in a code note: L3786 says "character budget" while
we express tokens -- a 4x difference nobody can settle from the wording.
Suite 1531 -> 1535, all green.

New AGT scanner flags the aggregate always-loaded cost of the agent listing
(every active agent's name+description is injected each turn so the model
knows what it can delegate to). Mirrors the SKL skill-listing pattern but
encodes the key honesty caveat: the agent-listing mechanism is INFERRED
(agents are absent from Claude Code's documented context breakdown), so the
token figure is an UPPER-BOUND estimate and the aggregate budget is a
config-audit heuristic anchored on 200k — not a CC-documented allotment.
- scanners/agent-listing-scanner.mjs + scanners/lib/agent-listing-budget.mjs
- 8 TDD tests (tests/scanners/agent-listing-scanner.test.mjs)
- AGT folds into the Token Efficiency health area (scoring.mjs)
- byte-stability: AGT added to strip-added-scanner (frozen v5.0.0 baselines
left untouched, same as OST/OPT); SC-5 default-output snapshot refreshed
- suite 1168 -> 1176 green

First detector of the 'is the config OPTIMAL?' axis (vs the existing 'correct?' scanners). New orchestrated scanner family CA-OPT (count 14->15), the deterministic half of the hybrid optimization lens.
CA-OPT-001 (low, Missed opportunity): a multi-step procedure in CLAUDE.md (>=6 consecutive numbered steps) that belongs in a skill. Reads recommendation + provenance from the best-practices register (BP-MECH-003). Conservative by design; the negative corpus proves null false-positives. Prose-judgment cases (lifecycle->hook, 'never'->permission) are deferred to the Chunk 2b opus analyzer.
Wiring mirrors OST: orchestrator entry, humanizer (OPT->'Missed opportunity' + family), scoring (OPT->'CLAUDE.md', existing area -> no new posture row -> byte-stable), strip-helper (OST,OPT), SC-5 regenerated under hermetic HOME (additive OPT entry only). 10 new tests; suite 1045->1055, self-audit A/A, readmeCheck passed (all verified with a clean HOME).
Note: the pre-existing TOK test reads the real ~/.claude (non-hermetic) -> run the suite with a clean HOME for deterministic results. Tracked as a separate follow-up.

New orchestrated scanner output-style-scanner.mjs — first new family since
SKL. Three findings, each pinned to a CONFIRMED V-row of the steering-model
plan + re-verified against code.claude.com/docs/en/output-styles:
- CA-OST-001 (medium, V10): user/project custom style missing
keep-coding-instructions:true (default false) → silently strips built-in
software-engineering instructions when active. Scoped to user/project.
- CA-OST-002 (low, V11): plugin style with force-for-plugin:true overrides the
user's selected outputStyle. Verifiseringsplikt correction — the plan bullet
said "project/user style," but force-for-plugin is plugin-styles-only per the
docs, so the check keys on source==='plugin'.
- CA-OST-003 (medium): settings outputStyle matching no built-in
(Default/Explanatory/Learning/Proactive, case-insensitive) nor discovered
custom style → dead config.
Byte-stability — a scanner addition, not a field addition. Growing the
scanners array + scanners_ok cannot be hidden by a field strip, but re-seeding
frozen v5.0.0 (the SKL precedent) would now bake in B2's hotspot triple +
claudeMd drift. So, per the B2 lesson, frozen v5.0.0 snapshots are PRESERVED
and the OST entry is stripped at compare time via new
tests/helpers/strip-added-scanner.mjs (wired into json/raw-backcompat + the
Step 5/6 humanizer tests); only SC-5 default-output is regenerated (additive
OST entry, diff reviewed). OST is fixture-gated (no output styles on
marketplace-medium / hermetic HOME → silent).
Wiring: orchestrator; humanizer (OST→Configuration mistake) + humanizer-data
OST family (title-coupled); scoring (OST→Settings, keeps 10 areas). Suite
1012→1023 (+11). Badges: scanners 14, tests 1023, TRANSLATIONS families 15.
Lore swept: README, CLAUDE.md, scanner-internals, humanizer.md. self-audit A/A.

Annotate every ranked TOK hotspot with the load-pattern triple
(loadPattern/survivesCompaction/derivationConfidence):
- hotspotLoadPattern() maps each discovery `type` → a deriveLoadPattern kind.
Rules reuse activeConfig.rules for precise `scoped` handling; claude-md maps
by scope. Two new deriveLoadPattern kinds back the rest: `command`
(on-demand — body loads on /invoke) and `harness-config` (external —
settings/keybindings/.mcp.json/hooks.json/plugin.json configure the CLI, not
the model context, so they cost no per-turn context tokens). Honest split:
the .mcp.json FILE is external; the MCP server's tool schemas are a separate
`always` hotspot.
Byte-stability — the opposite of B1's manifest. token-hotspots IS a byte-equal
SC-6/SC-7 CLI, and its hotspots ride inside scan-orchestrator + posture, so the
change touched SIX frozen-v5.0.0 comparisons across five test files. Resolved by
preserving the frozen baselines: a shared tests/helpers/strip-hotspot-load-pattern.mjs
strips the additive triple before each byte-equal compare (proves the original
schema is byte-identical). SC-5 default-output snapshots (scan-orchestrator +
token-hotspots) regenerated — diff reviewed as additive-only.
Tests 1008→1012. Self-audit A/A, scanner count unchanged at 13 (C bumps to 14).
Completes v5.6 B (B1 manifest + B2 token-hotspots).

The COL collision-scanner and the CLAUDE.md cascade resolve ~/.claude from
process.env.HOME (active-config-reader). Snapshot/byte CLIs were spawned with
the developer's real HOME, so they picked up installed plugins/skills and the
user CLAUDE.md — making the v5.0.0 + default-output snapshots machine- and
time-dependent. They were seeded 2026-05-01 with COL=1 (a real ~/.claude skill
collision) and drifted to COL=0 after the polyrepo split: 26 pre-existing
failures unrelated to Batch 1.
Fix (test-only, no production change):
- tests/helpers/hermetic-home.mjs — empty temp HOME, mirroring the pattern
collision.test.mjs already uses for the COL unit test.
- 7 harnesses spawn CLIs (or call lint()) under the hermetic HOME, so output
depends only on committed fixtures. Determinism verified across runs.
- Re-seeded all snapshots under hermetic HOME via SEED_SNAPSHOT/UPDATE_SNAPSHOT
(added a SEED guard to the frozen v5.0.0 byte tests). Snapshots now reflect
the fixture alone (COL=0, fixture-only activeConfig counts).
- Also re-seeded the unused env-aware snapshots (manifest/whats-active/
plugin-health), which had baked dozens of real ~/.claude skill/plugin names
into the committed repo — privacy cleanup.
Full suite: 812/812 green, stable across 3 runs.
