JesseMarkowitzandClaude Opus 5 59b5ebc2d8 v1.1 WP-C: browser release coverage
Drives in a real browser the reader workflows v1 proved only through the API
or the component suite, including an export that leaves the browser as a
file. Final run: 91 checks (the 38 existing M11 checks plus 53 new), 0 failed,
0 skipped, on the production build over trusted-LAN HTTPS.

- tools/m11_browser.py: scenarios for Retry and takes, Save Point create /
  restore / Redo, state correction (accepted, and a refused correction with
  its reason), narration length reaching each turn's prompt, failed
  generation (an unserved model blocked up front; a listed model that cannot
  narrate failing in the open) and recovery, and export download from the
  library and from campaign settings, imported into a fresh application.
  Rows are tagged M11 / WP-C and counted separately; --only for development.
  The M11 checks now wait on conditions instead of sleeping.
- tools/m11_webdriver.py: Firefox download preferences, a $HOME-only
  download folder, a download wait that ignores partial, empty, pre-existing
  and still-growing files, centred real clicks, tabs, and condition waits.
- tests/test_v11_c_browser_helpers.py: the download wait, prefs and $HOME
  guard, without a browser.
- frontend: a correction the story refused was presented as "Generation
  failed" with a Retry offer and a typed-input claim. It is now "That
  correction was not applied", not retryable, with the reason kept
  (errors.js, FailureNotice.jsx; 3 regression tests).
- DEVELOPMENT.md: the harness command, download profile and $HOME rule,
  what counts as a finished download, and the no-sleep rule.
- docs: V1.1-PLAN, VERSION v4.4, planning README,
  reports/v1.1/V1.1-WP-C-REPORT.md.

Open for the owner: "Correct" on an Important Facts row is always refused
(K1), and a partly refused correction is not reachable from the reader UI.

"""M11 §20-§21 and v1.1 WP-C: the release regression, in a real browser, on the frozen build.
python -m tools.m11_browser --out <dir> [--show] [--only name,name] [--no-narrator]
Run from `backend/`, with `frontend/dist` already built. `--out` must be under
`$HOME`: the browser's downloads are written inside it, and the snap Firefox can
write nowhere else.
**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, and a file that really lands
on disk.
## 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, a file on disk — and never
on class names, element ordering, or the narrator's prose.
**v1.1 WP-C adds a second rule: nothing waits by sleeping.** Every wait is on a
condition the page, the browser or the filesystem can show, and a condition that
already holds before the action it is meant to observe is not a wait for that
action. The M11 checks slept before four of their assertions; they now wait.
## The two suites
Every row is tagged with its suite, and the report counts each on its own:
- `M11`: the 38 checks of the v1 release regression, unchanged in name and in
what they assert.
- `WP-C`: the reader-facing behaviours v1 proved only through the API or the
component suite — Retry and takes, Save Points, state correction, narration
length, failed generation, and an export that leaves the browser as a file.
