docs(audits): commit the 2026-08-04 audit report per ADR-0006

[dlovell]

ADR-0006 places one mechanical obligation on the caller: commit each audit report to docs/audits/<date>-<scope>.md, because the auditor's "rerun and compare" promise is — in the ADR's own words — "vacuous while reports die in the invoking conversation."

I ran the audit of 88d16b4, acted on all three shapes (#109, #110, #112), and left the report in the conversation. That is precisely the failure the ADR exists to prevent. Without this, the M1–M9 measurement series, the seven mutation results, and the checked-and-dropped list all get re-derived from scratch next run.

Conformance after this PR:

ADR-0006 requirement	Status
Auditor reads the newest prior report before measuring	✅ read 2026-08-02-adr-0005-acceptance.md, re-ran M1–M7
Agent writes no files	✅
A disposal draft per shape	✅
Caller commits the report to docs/audits/	✅ this PR
Each shape filed, landed, or recorded	✅ #109, #110, #112

The report is verbatim apart from two caller additions:

1. A disposition table, so the next reader sees which shapes closed and where.
2. A correction block on Shape 3. Its "satisfied at introduction zero times in six" claim was falsified while reviewing docs: record two audit shapes as accepted, with reasons #112 — a selection effect, with feat: Nix devcontainer base — CI-published, multi-arch, default for non-seed overlays #41 and feat: track .claude/agents in git; per-subdir state symlinks (ADR-0003) #74 appearing in the report's own violation list while those same commits shipped at-introduction guards. Committing a known-false claim into the durable baseline would be worse than not committing it, so the correction ships with it, including the generalisable lesson: an "N for N" history claim needs the inverse query — are there contradicting instances outside the sampled set? — not just verification that the sampled ones are individually correct.

Docs only. pre-commit run --all-files clean.

Closing — holding the audit report out of git for now at the author's request. The file stays as a working draft; ADR-0006's commit step will happen separately once reviewed.
