M11 closeout: accept v1 release validation
The browser, offline and identity runs had last been taken on ef25b0a. The
closeout repeated them on the exact release-candidate tree, 3652dc6, whose
product code is identical to 96c1bf5, where the 100-turn evidence was run. No
product code changed, so the long-run evidence stands.

On 3652dc6:
- backend suite: 1421 passed, 17 skipped, 0 failed
- frontend suite: 161 of 161; lint clean
- production build clean
- docker build --no-cache: image SPA byte-identical to the local build
- browser regression: 38 of 38
- no-network container: 23 of 23
- identity diagnostic: 0 signals; the scripted self-test's detectors fire
- release-shaped smoke test from the image: 14 of 14

- M11 report: new S (exact-tree verification, including the identity
  results the report never carried) and T (acceptance record). Corrections:
  the REQUIRED FOR V1 count is 82, not 85, and L's browser narrator was
  qwen2.5:3b-instruct. P gains risks 16 and 17; risk 6 is widened.
- BUILD-MILESTONES.md: M11 COMPLETE / ACCEPTED, and a post-v1 backlog.
- V1-ACCEPTANCE-TESTS.md: the P release gate's result, and the P3
  disposition's run.
- planning/README.md, VERSION.md (v4.0), README.md: status, map, stop rule.
- tools/m11_browser.py: the G01 import wait could not fail, because the
  scenario's campaign is titled "Hidden Knowledge". It now waits for the
  imported source's row.

Found and carried, not fixed. The identity run stored protocol shapes the
extractor leaves, on 4 of 10 turns at a 4,096 window: event-call syntax and a
parroted length hint. The owner chose residual risk. The state rule's example
is fantasy, and the state lagged the narration. None occurs in the 100-turn
evidence.

No requirement changes. No release tag.

"""M11 §20-§21: the release regression, in a real browser, on the frozen build.
python -m tools.m11_browser --out <dir> [--show]
Run from `backend/`, with `frontend/dist` already built.
**A narrator is required**, from `AIDND_TEST_ENDPOINT`/`AIDND_TEST_MODEL`, and
the run refuses to start without one. `--no-narrator` opts out explicitly, and
then every check that needs a played turn *skips* and the run is marked
`partial` — it is a smoke test of the deterministic checks, not release evidence.
That is deliberate, and it is the second harness defect of this shape M11 has
found. Without a narrator no turn is ever played, so the campaign has no history:
Undo is correctly disabled, `D01` fails, the click that follows it throws, and a
run reports two failures that look exactly like a product regression and are not.
An unset environment variable must not be able to produce that. `--out` is
required on every harness here for the same reason — so the decision is made on
purpose rather than by omission.
## What this is and is not
It is the browser half of the release evidence: the M8 workflows re-run as
regression, the security behaviours that only exist in a browser, and the
accessibility properties M8 recorded as *checked by eye* and handed to M11 to
measure. It runs against the **built** SPA served by FastAPI — the production
path from `DEVELOPMENT.md` — because a Vite dev server is not what ships.
It is not a substitute for the component suite, which covers far more states far
faster. What lives here is what jsdom cannot answer: real layout, real focus,
real navigation, a real CSP, a real network stack.
## The rule this harness is built around
M8's review found five harness defects against seven product defects, and two of
the five were *masking* product defects. The lesson recorded there is that a
browser harness asserting on DOM structure, React internals or model wording
produces confident wrong answers. So every check below asserts on something the
product promises — a control's enabled state, a stored value, a request that was
or was not made, a computed style, an accessible name — and never on class names,
element ordering, or the narrator's prose.
