Dogfooding `/config-audit` (the router) against the repo, fasit written before
any run (docs/router-fasit.local.md, untouched). Every claim below is measured
behaviour, not a reading of the source.
1. Bare `<target-path>` inside the step-3 fence is a shell REDIRECTION, not an
argument. Measured in zsh: both CLIs failed before starting, no output file
was written, and the echoed status was 1 — inside the band the router's own
gate calls "continue normally". Quoting makes an unsubstituted placeholder
reach argv, so it fails in the CLI where the exit code means something.
Swept the whole class: 30 sites across 12 further command files, since a
defect in one file is a class until the opposite is measured. New guard:
command-placeholder-shell-safety.test.mjs.
2. The orchestrator's exit code was discarded. Two commands on one line share a
single trailing `echo $?`, which reports only the last: measured, an
orchestrator exit 3 echoed as posture's 0, so the "3 -> stop" gate could
never fire. Both statuses are now captured and echoed.
3. "Running 12 configuration scanners" — the orchestrator registers 16. The new
test binds the narrated count to the registry so the next scanner added
cannot re-stale it silently.
4. The Area Breakdown table hardcoded 7 rows; posture emits 9 quality areas.
Token Efficiency (a B on this repo) and Plugin Hygiene never reached the
user. Rows added, and the row set is now asserted against lib/scoring.mjs.
Label aligned: "MCP Servers" -> "MCP", as posture emits it.
5. Step 6 rendered "the headline line from the humanized stderr scorecard" and
forbade deriving a replacement — while step 3 sent posture's stderr to
/dev/null, as UX rule 2 requires, and the prose is absent from the JSON
payload (measured). The slot could only be improvised. posture's stderr now
goes to a file in the session dir, as commands/posture.md already did; the
user still never sees raw scanner output.
Also: `grep -q -- "--raw"` matched any argument CONTAINING --raw (measured on
`--rawdog` and on a path with --raw in it) — anchored to whole arguments.
SCOPE_FLAGS renamed SCOPE_FLAG, since zsh does not word-split and the plural
invited the M-BUG-45 shape.
command-shell-state-shape.test.mjs only recognised line-initial assignments, so
it reported the idiomatic `node …; STATUS=$?` capture as never assigned. Widened
to assignments after a separator; verified it still fails on a real cross-block
reference before trusting it.
Suite 1477 -> 1483, frozen v5.0.0 snapshots untouched.

Every command so far asked an addition question — what to add, what to move,
what it costs. Nothing asked what is no longer earning its always-loaded rent.
This adds that axis as a fourth lensCheck on the existing hybrid motor rather
than a new scanner or a 22nd command: the measured payoff (~18% of one file)
justifies a mode, not machinery.
It is the only lens that proposes REMOVING config, so it carries a guarantee
the others don't need: a load-bearing block is never a candidate. Precision is
asymmetric — a missed dead line costs a few tokens per turn, a deleted one
costs a wrong remote or a broken script — so the floor is decided in code
(lib/floor-exclusion.mjs) before the opus judge sees anything, never in prose.
Granularity is the leaf block, with two structural exceptions: a paragraph
ending in ':' merges with the list it introduces, and an ordered list is a
contract whose steps inherit floor from any sibling. Unordered lists
deliberately do not inherit — a load-bearing bullet and a disposable one
routinely share a list, and container-reasoning is the error the hand-built
ground truth exists to catch.
Verified against that ground truth (built before any classifier existed), with
the comparison machine-checked rather than read by eye: zero load-bearing
blocks proposed, 11/18 deletable groups surfaced, ~756 tok ~ 18% of a ~4300
token file — inside the pre-registered band. The first run found five floor
violations the synthesized fixture missed; each got a structural rule and a
fixture shape so it cannot regress.
Three real bugs the dogfood run exposed, all now covered:
- JS \b is ASCII-only, so /\bunngå\b/ never matches — every Norwegian keyword
ending in æ/ø/å was silently dead.
- A bare word/word is not a path; "pros/cons" vetoed the largest deletable
block until PATH_RE was tightened to rooted paths and globs.
- "Mid-sentence" must key on a preceding lowercase letter; the loose version
read **bold labels:** and quoted openers as entities, costing 4 of 11 groups.
BP-SUB-001 is grounded entirely in the Anthropic steering blog already cited by
BP-MECH-001..004 and asserts nothing from the talk that motivated the feature —
no "80%", no ablation figure.
Suite 1365 -> 1382/0. Frozen v5.0.0 snapshots untouched; plain optimize output
byte-identical on identical input (--subtract adds keys only when passed).
knowledge-refresh-cli's reference date moved to 2026-08-01: its premise that
every seed entry was verified 2026-06-20 expired when BP-SUB-001 got a genuine
verification date, and backdating the entry to fit the test would have been a
lie about when its source was checked.

The recall+precision halves of the CA-OPT hybrid motor for the three
mechanism-fit cases the deterministic OPT scanner (2a) deliberately skips:
lifecycle→hook (BP-MECH-001), unscoped path-specific→rule (BP-MECH-002),
absolute "never"→permission (BP-MECH-004).
New:
- scanners/lib/lens-prefilter.mjs — cheap, recall-oriented line scan of the
CLAUDE.md body; detector names mirror the register lensCheck fields; skips
fenced code, gates the path class on an instruction verb. Pure + 13 tests.
- scanners/optimize-lens-cli.mjs — discovery + OPT scanner + pre-filter; attaches
only the CONFIRMED register entry to each candidate (unverifiable → dropped,
Verifiseringsplikt); emits {deterministic, candidates, register, counts}.
- agents/optimization-lens-agent.md — opus precision gate (7th agent, orange):
reads the real CLAUDE.md, drops low-confidence candidates, keeps only genuine
opportunities, cites register id + source.
- commands/optimize.md — /config-audit optimize orchestrates pre-filter→agent→report.
Agent-driven → deliberately NOT byte-stable (own command, outside the snapshot
suite). No new orchestrated scanner → scanner count stays 15. Counts: agents
6→7, commands 18→19, suite 1055→1068. Self-audit A/A unchanged, readmeCheck
passed (clean HOME). Plan: docs/v5.7-optimization-lens-plan.md.
