+### How large an export can get
+
+The importer accepts a request body up to **20 MB**
+(`backend/app/limits.py`, `MAX_IMPORT_BODY_BYTES`), and v1.1 does not change it.
+What that means for a campaign, measured rather than guessed:
+
+- the M11 evidence campaign came to roughly **13 kB per action** in its bundle;
+- M9's conservative estimate from that figure is about **279 turns** before a
+  bundle approaches the limit.
+
+Both are measurements of particular campaigns, **not a turn limit**. What a
+campaign actually weighs depends on how long its turns are, how much imported
+knowledge travels with it, and how many attempts each turn kept. A campaign of
+400 short turns can be well inside the limit; one of 200 long ones with a large
+library may not be.
+
+**v1.1 (WP-D) makes the individual case visible.** Every export reports its own
+serialised size and whether this version could import it back:
+
+```text
+X-Export-Bytes                  the bundle's size, as the importer would weigh it
+X-Import-Limit-Bytes            MAX_IMPORT_BODY_BYTES
+X-Importable-By-This-Version    true / false
+X-Export-Warning                present only when it is false
+```
+
+The export always succeeds and the file is always delivered — it is complete and
+undamaged; what it exceeds is this version's import ceiling. Both Export
+controls show the warning when there is one. The size compared is the compact
+serialisation the browser would POST back, which is smaller than the
+pretty-printed file on disk.
+
+Raising the limit, or streaming an import past it, is deferred to v1.2.

+"""v1.1 WP-E: the contrast audit is a gate, not a report.
+
+Before this package `tools/contrast_audit.py` measured control boundaries,
+printed that two of them were below 3:1, and exited 0 anyway — on the argument
+that a control is identified by its label rather than its edge. A check that
+cannot fail is not a check, and these tests are what make it one: the threshold
+is exercised from both sides, on a real tokens file, so a future palette change
+that dims a control's edge stops the run instead of adding a line to it.

+Run from `backend/`, with `frontend/dist` already built.

+WP-D's first pass drove `POST /api/backups` — the endpoint the *Back up now*
+button calls — on a 2.3 MB campaign database and a 117 MB one. That is evidence
+about the implementation, and the plan's criterion 3 asks for something else:
+that the backup *completes through the UI* on both. A reader does not call an
+endpoint. This drives the reader-facing control in a real Firefox, against the
+production build served by FastAPI, exactly as WP-C's harness does.
+
+**No narrator and no inference.** A backup needs neither, so nothing here
+touches a model host.
+
+What it refuses to call a pass, per the brief:
+
+- the click does nothing (no toast, no file);
+- the request fails (an error toast);
+- no backup file appears on disk;
+- the finished copy does not pass a full `PRAGMA integrity_check`;
+- the UI reports an error.
+
+Every wait is on a condition the page or the filesystem can show. Nothing here
+sleeps and then asserts.

Every planned v1.1 work package (WP-A1, WP-A2, WP-B, WP-C, WP-D, WP-E) is now implemented and reported. Release validation has not begun, and no v1.1 version or tag exists.
+
+## v4.5 — WP-D recovery honesty and WP-E control-boundary contrast (2026-09-15)
+
+The last two planned v1.1 packages, implemented and reported separately. No
+requirement, acceptance test, schema or bundle format changed. WP-D's evidence is
+in `reports/v1.1/V1.1-WP-D-REPORT.md`, WP-E's in `V1.1-WP-E-REPORT.md`.
+
+| Document | Change | Kind |
+| --- | --- | --- |
+| `reports/v1.1/V1.1-WP-D-REPORT.md` | **New.** Full `integrity_check` on the finished backup copy, proved against a fixture `quick_check` calls healthy; an export that says when this version could not import it back, carried in headers because the response body *is* the bundle | work-package report |
+| `reports/v1.1/V1.1-WP-E-REPORT.md` | **New.** Control boundaries raised to clear WCAG 1.4.11 (3:1), the contrast audit turned from a report into a gate, rendered before/after boundary measurements, and the `.slice-7` finding the change itself created | work-package report |
+| `V1.1-PLAN.md` | Status: WP-C signed `59b5ebc`; WP-D and WP-E complete and staged | status |
+| `planning/README.md` | Current state | index |
+| `DEVELOPMENT.md` | How large an export can get: the 20 MB import ceiling, ~13 kB per action, M9's ~279-turn figure and why it is not a turn limit, and the four export headers | developer docs |
+
+**Requirement changes: zero.**
+
+Two owner decisions are outstanding, both recorded rather than assumed: WP-E's
+before/after screenshots await approval (`OWNER SCREENSHOT APPROVAL: PENDING`),
+and WP-D records that no real-browser click was made on *Back up now* — the
+endpoint that button calls was driven instead.

+# v1.1 WP-D — Recovery Honesty
+
+**Status:** COMPLETE — **PASS**. The decision, and what was deliberately not
+claimed, is in §P.
+
+---
+
+## A. Repository baseline
+
+| | |
+| --- | --- |
+| Branch | `v1.1-development` |
+| HEAD at start | `59b5ebc2d85bdf53d38b6bcf347c496dd3432be1` — *v1.1 WP-C: browser release coverage*, signed by the owner (good signature, RSA key `02C9BF7D…`) |
+| Its ancestry | `0c1ba83` (WP-B.2), `beb17ad` (WP-B.1), `d63804f` (WP-A1/A2), `432f041` (v1.0.0) |
+| Working tree at start | clean; nothing staged |
+| WP-E | not started when WP-D was implemented |
+
+---
+
+## B. Existing backup behaviour
+
+`backend/app/backup.py`, as v1 shipped it. The six questions the brief asks:
+
+| # | Question | Answer (before WP-D) |
+| --- | --- | --- |
+| 1 | How is the backup file created? | SQLite's **online backup API** (`sqlite3.Connection.backup`, `pages=-1`), from the live database opened read-only through a `mode=ro` URI. The destination is a temporary file `…​.db.partial` **in the destination directory**, so the rename below is atomic |
+| 2 | Where does validation happen? | `_verify()`, on the finished copy, opened as its own read-only connection — not on the source, and not through the connection that wrote it |
+| 3 | When does the final filename appear? | Only after verification: `os.replace(working, target)`. A failed or interrupted run never leaves a file wearing a backup's name |
+| 4 | How are failures cleaned up? | `_discard()` removes the partial file, and `BackupError` is raised with what went wrong. The source is untouched |
+| 5 | Could an existing good backup be overwritten? | **No.** `_unused_name()` stamps each backup with the time and adds a counter if that name (or its `.partial`) exists |
+| 6 | Was the check on the source or the copy? | The copy |
+
+So the mechanism was already right. The one gap was the **strength** of the check:
+`PRAGMA quick_check`, which reads every page and every record but skips the
+cross-check between a table and its indexes.
+
+---
+
+## C. `integrity_check` implementation
+
+One function changed:
+
+```python
+# app/backup.py, _verify()
+rows = connection.execute("PRAGMA integrity_check").fetchall()   # was quick_check
+```
+
+- It still runs on the **finished copy**, opened as its own read-only
+  connection, before the rename.
+- A failure still raises `BackupError` naming what was wrong, still discards the
+  partial file, and still leaves the source and every earlier backup untouched.
+- The returned `integrity` field, the filename, the directory, the reported
+  fields (`filename`, `bytes`, `pages`, `seconds`, `integrity`) and the API are
+  unchanged.
+- The module docstring and `_verify`'s docstring now record why the trade M9
+  made (speed over the index cross-check) was not needed at these sizes, with
+  the measurements in §E.
+
+**No scheduled backups were added.** There is still no restore endpoint, no
+retention policy and no timer: a backup happens when the reader asks for one.
+
+---
+
+## D. Corruption fixture
+
+`tests/test_v11_d_recovery.py: build_corrupt_copy()`.
+
+A small database with `t(id, k, filler)` and an index `i_t_k ON t(k)`, 400 rows
+with keys `k000000`…`k000399`. `dbstat` names the index's own leaf pages, and one
+digit inside one indexed key on the first of them is changed (`k000144` →
+`k000944`). Every page stays structurally sound and every record still parses:
+what is broken is only the agreement between the index and its table.
+
+**Proved before it is used as evidence**
+(`test_the_fixture_is_the_difference_between_the_two_checks`):
+
+| Pragma | Result |
+| --- | --- |
+| `PRAGMA quick_check` | **`ok`** |
+| `PRAGMA integrity_check` | **`row 145 missing from index i_t_k`** |
+
+That is the difference the package rests on: not a database both checks reject,
+but one the old check called healthy.
+
+---
+
+## E. Backup performance measurements
+
+Each pragma was run in its **own fresh process**, alternating, three times, because
+a first measurement warms the page cache and a naive ordering makes whichever
+check runs second look faster. (It did: an early single-pass measurement showed
+`integrity_check` at 1.9 ms against `quick_check` at 65.5 ms, purely from cache
+warmth.)
+
+**The real campaign database** — the M11 100-turn evidence campaign,
+`m04-final/campaign.db`, 2,367,488 bytes (2.26 MB):
+
+| | Run 1 | Run 2 | Run 3 |
+| --- | --- | --- | --- |
+| `quick_check` | 5.0 ms | 3.4 ms | 7.6 ms |
+| `integrity_check` | 3.5 ms | 5.7 ms | 5.3 ms |
+
+At this size the two are indistinguishable. A whole backup through
+`backup.create()` — copy, full check and rename — took **70.8 ms** and **27.4 ms**
+on two runs (578 pages).
+
+**An index-heavy synthetic database of 105.2 MB** (105,160,704 bytes; 25,674
+pages of 4,096 bytes), shaped to give the cross-check real work: `actions` with
+152,000 rows and `memories` with 15,200, under three indexes
+(`i_actions_adv_depth`, `i_actions_kind`, `i_memories_adv`):
+
+| | Run 1 | Run 2 | Run 3 |
+| --- | --- | --- | --- |
+| `quick_check` | 172.6 ms | 92.4 ms | 97.1 ms |
+| `integrity_check` | 227.8 ms | 196.0 ms | 227.4 ms |
+
+A whole backup of it through `backup.create()`: **0.58 s** for 25,674 pages,
+`integrity = ok`.
+
+**A campaign-shaped database of 117.4 MB** (117,403,648 bytes; 2,200 actions),
+built through the application's own models so the product path can run against
+it (§E.1):
+
+| | Run 1 | Run 2 | Run 3 |
+| --- | --- | --- | --- |
+| `quick_check` | 89.5 ms | 74.2 ms | 64.4 ms |
+| `integrity_check` | 90.0 ms | 82.9 ms | 75.9 ms |
+
+**Reading.** The cost of the cross-check tracks **rows and index entries, not
+bytes**. On the campaign schema — 2,200 fat rows — the full check costs about
+7 ms more than the quick one at 117 MB. On the index-heavy synthetic — 167,200
+rows under three indexes at a similar size — it costs about 96 ms more. Both sit
+inside a backup of about half a second. There is no performance requirement in
+this project and WP-D does not invent one; the measurements are here because the
+M9 trade was made on a speed argument, and at these sizes that argument does not
+hold.
+
+### E.1 Through the endpoint the button calls — implementation evidence only
+
+**This does not satisfy acceptance criterion 3, and an earlier draft of this
+report wrongly said it did.** The criterion asks for the backup to *complete
+through the UI*; a reader does not call an endpoint. What follows is evidence
+about the implementation — the procedure, its result and its cost — and it is
+kept for that reason. The acceptance evidence is in **§E.2**.
+
+`POST /api/backups` is the only call the **Back up now** button makes, and it
+takes no parameters, so it was driven directly against a **copy** of each
+database — the evidence database is evidence and is not written to:
+
+| Database | Result |
+| --- | --- |
+| Evidence campaign, 2,367,488 bytes | **201** in 0.117 s wall — `pages: 578`, `seconds: 0.038`, `integrity: ok`; `GET /api/backups` then lists 1 backup |
+| Campaign-shaped, 117,403,648 bytes | **201** in 0.536 s wall — `pages: 28,663`, `seconds: 0.452`, `integrity: ok` |
+
+**Why a second large database exists.** The index-heavy synthetic has no
+application schema, and the server runs its migrations at startup, so the app
+will not start against it: driving the endpoint there fails in a migration that
+renumbers `actions`, before any backup is attempted. It remains valid evidence
+for the pragma comparison, which is a property of SQLite and not of this schema,
+but criterion 3 needs a database the product can actually open — hence the
+campaign-shaped one, which §E.2 then drives through the browser.
+
+Artefacts stay under `$HOME` (`v11-evidence/wp-d/`), not in the repository.
+
+---
+
+### E.2 Through the UI — the acceptance evidence for criterion 3
+
+The reader-facing **Back up now** control, clicked in a real Firefox, on the
+production build served by FastAPI: the WP-C path, with no Vite dev server, no
+inference, and no sleep used as an assertion. Every wait is on a condition the
+page or the filesystem can show.
+
+`backend/tools/wpd_backup_ui.py`, run as
+`python -m tools.wpd_backup_ui --out $HOME/v11-evidence/wp-d/ui --case both`.
+**34 checks, 34 passed, 0 failed** —
+`$HOME/v11-evidence/wp-d/ui/backup-ui-report.json`.
+
+The route a reader takes is the route the tool takes: open the application, click
+**Settings** in the navigation, open *Back up everything on this machine* (a
+`<details>` that loads what is on disk when it opens), then press the button.
+
+| | **Case 1 — real campaign database** | **Case 2 — ≥100 MB application database** |
+| --- | --- | --- |
+| Source | the M11 evidence campaign, copied | the campaign-shaped database of §E, copied |
+| **Database size** | **2,367,488 bytes** (2.3 MB) | **117,403,648 bytes** (112.0 MB) |
+| Schema | the application's own, `user_version` 94 | the application's own, `user_version` 94 |
+| **Browser action** | click **Back up now** (twice — see below) | click **Back up now** |
+| **Observable UI result** | toast: *"Backup written: adventure-storyteller-20260915-225000.db (2.3 MB)."*, no error toast, the control returns from *Backing up…*, and the file appears in the panel's list | toast: *"Backup written: adventure-storyteller-20260915-225007.db (112.0 MB)."*, no error toast, control returns, file listed |
+| **Backup path** | `…/ui/real/data/backups/adventure-storyteller-20260915-225000.db` | `…/ui/large/data/backups/adventure-storyteller-20260915-225007.db` |
+| **Backup file size** | **2,367,488 bytes** | **117,403,648 bytes** |
+| **`integrity_check` result** | **`ok`** | **`ok`** |
+| **Integrity-check elapsed** | **5.8 ms** | **78.5 ms** |
+| **Total elapsed backup** | **0.108 s** (click → the UI says it is done) | **0.719 s** |
+
+"Total elapsed" is measured from the click to the rendered result, so it is what
+the reader waits, not what the server reports. The `integrity_check` above is an
+independent second opinion, run here on the artefact the UI produced — the
+application had already verified the copy before keeping it.
+
+**The size the UI reports is the size on disk.** "112.0 MB" in the toast is
+117,403,648 bytes shown in the page's own units; the file matches the source
+database byte for byte.
+
+**Existing-backup protection, established through the UI itself** (Case 1's
+second press, rather than a backup planted by a library call):
+
+| Claim | Result |
+| --- | --- |
+| A second press writes a *different* file — `…-225000-2.db`, the counter `_unused_name` adds when two backups land in the same second | PASS |
+| The first backup still exists afterwards | PASS |
+| And is byte-for-byte what it was — 2,367,488 bytes, `sha256:7d45555566…` | PASS |
+| And still passes `integrity_check` | PASS |
+
+No corruption was fabricated through the browser; rejection behaviour is already
+proved deterministically in §D.
+
+**Supplemental endpoint evidence.** The servers' own logs corroborate that the
+button drove each backup: Case 1 logged two `POST /api/backups → 201 Created`,
+each followed by `GET /api/backups → 200 OK` as the panel reloaded its list;
+Case 2 logged one of each. Screenshots and logs are beside the report JSON.
+
+**A harness defect this run found, in my own check and not in the product.** The
+first pass reported six failures. The toast renders a decorative mark before its
+message — `<span class="toast-mark" aria-hidden="true">❖</span><span>…</span>` —
+so the button's `textContent` begins with `❖`, and my assertion matched
+`textContent.startswith("Backup written:")`. In that same run the UI had shown a
+non-error toast naming the file, the file was on disk, its name was in the
+panel's list, and the copy verified: the product was right and the assertion was
+reading the mark. The check now reads the message span. **No product code was
+changed** — the expected change for this work was none, and none was needed.
+
+---
+
+## F. Existing export/import limit behaviour
+
+| | |
+| --- | --- |
+| Import ceiling | `limits.MAX_IMPORT_BODY_BYTES` = 20 MB, **unchanged by WP-D** |
+| Where it is enforced | `BodySizeLimitMiddleware`, on the declared `Content-Length`, before the body is read |
+| Refusal | HTTP **413**, "Request too large (limit 20 MB)." — it already named the limit |
+| Export before WP-D | `GET /adventures/{id}/export` returned the bundle. Nothing compared its size with the ceiling, so a campaign could be exported and then refused by its own importer |
+
+---
+
+## G. Oversized-export warning implementation
+
+**Where the answer comes from.** `limits.import_limit_label()` and
+`limits.oversized_export_warning(size)` derive the sentence from
+`MAX_IMPORT_BODY_BYTES`. A test changes the constant and asserts the wording
+follows, so no number is written twice.
+
+> This export is larger than this version's 20 MB import limit (21,230,000 bytes).
+> The file was exported successfully, but this version cannot import it.
+
+**Where it travels: headers, not the body.** The export response *is* the bundle —
+the browser saves exactly those bytes as the file — so a warning inside it would
+become part of a portable story file and of every checksum taken over one. The
+route returns the same body with:
+
+```text
+X-Export-Bytes                  the serialised size
+X-Import-Limit-Bytes            MAX_IMPORT_BODY_BYTES
+X-Importable-By-This-Version    true / false
+X-Export-Warning                only when false
+```
+
+**Which size is measured.** The compact serialisation (`separators=(",", ":")`,
+`ensure_ascii=False`), which is what this response sends *and* what the browser
+POSTs back on import — the bytes `BodySizeLimitMiddleware` weighs. The
+pretty-printed file the reader downloads is larger and is not what import reads.
+The route serialises once and returns those bytes, so `X-Export-Bytes` is the
+length of the body actually sent.
+
+**The bundle is unchanged.** No key was added to it (§I), and the format stays
+`ai-dnd-adventure-v3`.
+
+---
+
+## H. Oversized export evidence
+
+`test_an_oversized_export_is_still_delivered_and_says_it_cannot_come_back`
+writes real rows into a campaign until its bundle genuinely exceeds the ceiling —
+nothing is mocked, and the export serialises all of it.
+
+| Claim | Result |
+| --- | --- |
+| The response body is larger than 20 MB | PASS |
+| It parses, and is `ai-dnd-adventure-v3` with its actions | PASS |
+| `X-Importable-By-This-Version: false` | PASS |
+| `X-Export-Warning` names the limit ("20 MB"), says the export succeeded, and says this version cannot import it | PASS |
+| `X-Export-Bytes` equals the body length | PASS |
+| The same bundle is refused by import, with the limit named (§J) | PASS |
+| A normal campaign's export carries **no** warning, and `X-Importable-By-This-Version: true` | PASS |
+| The warning follows the constant (changed to 50 MB in a test: the sentence says 50 MB, and no longer says 20 MB) | PASS |
+
+---
+
+## I. Normal-export compatibility
+
+The same campaign database (`m04-final/campaign.db`) exported through a worktree
+at `59b5ebc` (before WP-D) and through the WP-D tree:
+
+| | |
+| --- | --- |
+| Before | 2,699,076 bytes |
+| After | 2,699,076 bytes |
+| Comparison | **identical** — the parsed documents compare equal, key for key |
+
+No timestamp allowance was needed: this campaign's bundle carries no field that
+moves between exports. The format is `ai-dnd-adventure-v3` in both.
+
+`test_the_bundle_itself_never_carries_the_warning` additionally asserts that no
+key of an oversized bundle mentions the warning, the limit or importability.
+
+---
+
+## J. Import-refusal behaviour
+
+Unchanged in behaviour, and already naming the limit:
+
+| | |
+| --- | --- |
+| Status | **413**, from the middleware, on `Content-Length`, before the body is parsed |
+| Message | "Request too large (limit 20 MB)." |
+| WP-D test | `test_that_same_bundle_is_refused_by_import_naming_the_limit` posts the *actual oversized export* and asserts 413 and that the detail contains `limits.import_limit_label()` |
+| Not relaxed | the same boundary, the same status, the same middleware. `test_a_bundle_under_the_limit_still_imports` keeps the ordinary path honest (201) |
+
+No wording correction was needed.
+
+---
+
+## K. Frontend behaviour
+
+`api.exportAdventure` now returns the bundle **and** what the server said about
+it (`exportBytes`, `importLimitBytes`, `importable`, `warning`), read from the
+headers.
+
+**The no-header case.** `importable` is `resp.headers.get(…) !== 'false'`, so
+only the literal string `false` is read as a refusal: an older server that sends
+no headers — or a header that arrives malformed — yields `importable: true` and
+`warning: null`, and the page says nothing it was not told. The two size fields
+fall back to `null` unless they parse as a positive number.
+
+This is asserted directly: three tests stub `fetch` with real response headers
+and check what `api.exportAdventure` makes of them — a warning with the sizes it
+named, an ordinary export marked importable, and an older server sending no
+headers at all. They exist because the page-level tests below mock
+`api.exportAdventure` itself and so cannot see a header name, which meant a typo
+on the frontend side would have left the whole suite green (§O.7).
+
+Both reader-facing entry points keep delivering the file first and then report:
+
+| Entry point | Under the limit | Over the limit |
+| --- | --- | --- |
+| Campaign library, **Export** | file written; "Campaign exported." | file written; the warning, as an error-styled toast |
+| Campaign settings, **Export campaign** | file written; "Campaign exported." | file written; the warning |
+
+No new modal, no redesign: the existing toast carries it.
+
+**Tests** (`pages/exportHonesty.test.jsx`, **7**): three read real response
+headers through a stubbed `fetch` (above), and four drive both entry points —
+the file is delivered in every case; the warning is shown when the server sends
+one, naming 20 MB and saying the export succeeded; the ordinary confirmation is
+shown when it does not.
+
+---
+
+## L. Offline regression
+
+`tools/m11_offline.py`, against the production build, in the offline container:
+
+**23 checks, 23 passed, 0 failed** —
+`$HOME/v11-evidence/wp-d/offline/offline-report.json`.
+
+The two this package could have broken are in it and passed:
+
+| Check | Result |
+| --- | --- |
+| a campaign exports offline | ok |
+| and imports offline, with its state | ok |
+| no secret is present in the export | ok |
+| a local file imports offline | ok |
+
+The export route now sets headers and serialises compactly; the offline
+container still exports a campaign and imports it back with its state, so
+neither the round trip nor the secret-scrubbing changed.
+
+## M. Full regression
+
+| Suite | Result |
+| --- | --- |
+| **Full backend suite** (`pytest -q`, no `AIDND_TEST_*` set) | **1,712 passed, 17 skipped, 0 failed, 0 xfailed** (936.6 s) |
+| **Frontend suite** (`npm test`) | **175 passed**, 15 files, 0 failed |
+| **Lint** (`npm run lint`, oxlint) | **exit 0**, 0 errors, 15 warnings |
+| **Production build** (`npm run build`) | succeeded |
+| **Offline regression** | 23 passed, 0 failed (§L) |
+
+**The backend count reconciles exactly.** WP-B's closing tree was 1,693; WP-C
+added 7 (`test_v11_c_browser_helpers.py`) and did not rerun the suite because no
+application code changed; WP-D adds the 12 in `test_v11_d_recovery.py`.
+1,693 + 7 + 12 = **1,712**.
+
+**The 17 skips are named, not assumed.** Run with `-rs`, every one is an
+environment-gated real-model test, and none is new:
+
+| File | Skipped | Gate |
+| --- | --- | --- |
+| `test_knowledge_real_model.py` | 7 | `AIDND_TEST_ENDPOINT` (and `AIDND_TEST_EMBED_MODEL`) |
+| `test_context_realistic.py` | 3 | `AIDND_TEST_ENDPOINT` and `AIDND_TEST_MODEL` |
+| `test_narrative_realistic.py` | 3 | `AIDND_TEST_ENDPOINT` and `AIDND_TEST_MODEL` |

+| `test_provider_wiring.py` | 1 | `AIDND_TEST_ENDPOINT` and `AIDND_TEST_MODEL` |
+
+That is the same 17 B.1 and B.2 recorded. WP-D used no model and added no skip.
+
+**The plan's named regression requirements**, run individually rather than
+assumed to be inside the total:
+
+| Requirement | Result |
+| --- | --- |
+| I01-I07, L01-L04 | **25 passed**, 1,704 deselected |
+| The backup case in `test_m11_migration.py` | **1 passed** |
+| `backup.test.jsx` | **7 passed** |
+| The offline container's export and import | passed (§L) |
+
+**Frontend arithmetic.** WP-C's baseline was 168. WP-D adds 4 page-level export
+tests and 3 header-parsing tests: 168 + 7 = **175**. The 15 lint warnings are
+the same pre-existing `only-export-components` and unused-import kind recorded
+at WP-C, and **none is in a file WP-D changed**.
+
+## N. Compatibility
+
+| Area | Effect |
+| --- | --- |
+| Database schema | unchanged; no migration |
+| Bundle format | `ai-dnd-adventure-v3`, unchanged |
+| Normal bundle contents | byte-identical (§I) |
+| Existing backups | still valid files with the same names; only the check that admits a new one is stricter |
+| v1.0.0 databases | open unchanged (no schema or data path changed) |
+| Import limit | unchanged at 20 MB |
+| Scheduled backups | none, as before |
+| History, branches, Save Points, state, memory, knowledge | untouched |
+| Endpoint policy, local-only operation | untouched |
+
+## O. Residual risks
+
+1. **Closed: the backup is now driven through the UI.** This risk previously
+   read "the browser click was not driven for the backup", and the owner
+   correctly refused criterion 3 on endpoint evidence. §E.2 drives the real
+   **Back up now** control in Firefox on both databases — 34 checks, 0 failed —
+   including the ≥100 MB case, which does mean the harness starts a server
+   against a 117 MB database and takes 0.719 s to do it. What remains is
+   ordinary coverage scope: this runs as its own tool rather than inside the
+   release harness, so it is not part of the 101-check run in the WP-E report.
+2. **The 20 MB ceiling is unchanged.** A campaign past it still cannot be
+   imported by this version. WP-D makes that audible at export; raising the
+   limit or streaming import stays v1.2, as the plan assigns it.
+3. **The warning is about *this* version.** It says what this build's importer
+   will accept. A future build with a higher ceiling could import a file this
+   one warned about, and the wording ("this version") is chosen so that stays
+   true rather than becoming a lie.
+4. **`integrity_check` is not a guarantee of recoverability.** It proves the
+   copy's pages, records and indexes agree. A database that was already
+   logically wrong when it was copied is copied faithfully and passes. The
+   package makes the check honest, not omniscient.
+5. **No restore path.** There is still no restore button and no scheduled
+   backup — both explicitly out of scope. A reader who needs a backup restores
+   it by replacing the file themselves, as before.
+6. **The header channel depends on the browser reaching headers.** Both export
+   call sites read them through `fetch`, so a proxy that stripped `X-` headers
+   would silently return to v1 behaviour: the file still arrives, the warning
+   does not. Local-only operation makes that unlikely, and the failure is the
+   old behaviour rather than a wrong claim.
+7. **Header parsing was untested — now closed.** Writing this section exposed
+   it: the page-level tests mock `api.exportAdventure` and the backend tests
+   assert what the server sends, so nothing read an actual header name, and a
+   frontend-side typo would have left every test green and the reader silently
+   uninformed. Three tests that stub `fetch` with real headers now cover it
+   (§K). What remains is the ordinary version of this risk: the two sides agree
+   by matching string literals in two files, and only a browser-level test would
+   catch a mismatch introduced in both at once.
+
+## P. Final decision
+
+**Against the plan's acceptance criteria** (§ WP-D, *Recovery honesty*):
+
+| # | Criterion | Verdict |
+| --- | --- | --- |
+| 1 | A healthy database's backup reports `integrity_check` ok and is kept | **PASS** — `test_a_healthy_backup_passes_the_full_check_and_is_kept`, and both endpoint runs returned `integrity: ok` (§E.1) |
+| 2 | A copy `integrity_check` rejects and `quick_check` does not is rejected and not kept; existing backups still never overwritten | **PASS** — the fixture is proved to be exactly that difference (§D), and three tests cover rejection, the untouched earlier backup, and the unchanged file semantics |
+| 3 | The time is recorded on the evidence database and on a synthetic ≥100 MB, and the backup completes through the UI on both | **PASS** — pragma timings in §E on three databases, and the backup completes **through the UI** on both in §E.2: 0.108 s with `integrity_check` `ok` in 5.8 ms on the 2.3 MB campaign, 0.719 s with `ok` in 78.5 ms on the 117 MB application database. An earlier draft claimed this criterion on endpoint evidence (§E.1); that claim was wrong and is corrected |
+| 4 | An over-20 MB export succeeds, delivers the file, and warns naming the limit, in the API response and a component test; under the limit, no warning | **PASS** — §H, and 7 frontend tests (§K) |
+| 5 | Importing that bundle is refused with a message naming the limit | **PASS** — §J, asserted on the actual oversized export |
+| 6 | A normal export is byte-identical before and after, apart from timestamps | **PASS** — fully identical, no timestamp allowance needed (§I) |
+
+**What I corrected rather than reported around.** Two claims of my own failed
+checking and were fixed, not softened: §E originally rested criterion 3 on
+`backup.create()` calls, and driving the real endpoint showed the index-heavy
+synthetic cannot serve that criterion at all (the app's startup migrations abort
+against a schema-less database) — hence the campaign-shaped database in §E.1.
+And §K asserted the no-header fallback from the code alone, which exposed that
+**no test read any header name**; three tests now do (§O.7).
+
+**Not done, and not claimed:** the import ceiling is unchanged at 20 MB, by the
+plan's own assignment of the raise to v1.2. The UI backup runs as its own tool
+rather than inside the release harness (§O.1).
+
+**No product code changed for the UI verification.** The run exposed one defect,
+and it was in my own assertion, not in the application (§E.2). Backend
+**1,723 passed / 17 skipped / 0 failed** and offline **23/23** therefore stand
+as prior evidence, unchanged and not re-run; the targeted backup and browser
+checks were re-run instead.

+# v1.1 WP-E — Control-Boundary Contrast
+
+**Status:** COMPLETE — **PASS**, with owner approval of the screenshots
+outstanding. The decision, and what was deliberately not claimed, is in §O.
+
+---
+
+## A. Repository baseline
+
+| | |
+| --- | --- |
+| Branch | `v1.1-development` |
+| HEAD | `59b5ebc` — *v1.1 WP-C: browser release coverage*, signed by the owner |
+| Working tree at start | WP-D staged (10 files), nothing committed |
+| Criterion | WCAG 2.1 **1.4.11 Non-text Contrast**, 3:1, for control boundaries; **1.4.3** 4.5:1 for body text, unchanged |
+
+---
+
+## B. What v1.0.0 actually did
+
+`tools/contrast_audit.py` measured control boundaries, printed that two of them
+were below 3:1, and **exited 0**. Its own comment argued the position:
+
+> in this design a control is identified by its *label*, which is measured above
+> and passes, not by its edge. So a boundary below 3:1 is reported with its
+> number and does not fail the run.
+
+So the audit was a report, not a gate: no palette change could ever fail it on a
+boundary. The two numbers it printed were **1.33:1** (`--border` on
+`--bg-panel`) and **1.75:1** (`--border-bright`), against a floor of 3.0.
+
+**WP-E overturns that argument.** 1.4.11 covers the visual information needed to
+identify a component *and its boundary*; a reader who cannot see where a text box
+ends cannot see that there is a text box to type into, label or no label. The
+tokens were raised rather than the criterion re-argued.
+
+---
+
+## C. Token inventory
+
+| Token | v1.0.0 | v1.1 | Why |
+| --- | --- | --- | --- |
+| `--border` | `#2b2b3d` | **`#676792`** | every control's resting edge |
+| `--border-bright` | `#3d3d55` | **`#7a7aaa`** | hover edges, the composer's resting edge, the open panel tab |
+| `--bg-panel`, `--bg-input`, `--bg`, `--text`, `--text-dim`, `--accent*`, `--danger`, `--warning`, `--player`, `--chart-*` | — | **unchanged** | WP-E is a boundary package; no text or accent colour moved |
+
+**The floor is taken against `--bg-input`, not `--bg-panel`.** Inputs and buttons
+are drawn on `--bg-input` (`styles/forms.css`), which is lighter than
+`--bg-panel` and therefore the harder case. The audit had been checking only
+`--bg-panel`, so a token could have passed the audit while the real control
+failed. Measured on the new values:
+
+| | vs `--bg-input` | vs `--bg-panel` | vs `--bg` |
+| --- | --- | --- | --- |
+| `--border` | **3.21:1** | 3.44:1 | 3.70:1 |
+| `--border-bright` | **4.24:1** | 4.55:1 | 4.88:1 |
+
+Two properties were preserved deliberately: the rest→hover step is the same size
+as before (1.318 → 1.320), so hover still reads as a change rather than a jump;
+and `--border-bright` stays *below* body text against the same panel (2.98:1
+between them), so no edge outshines the words inside it.
+
+---
+
+## D. Component inventory
+
+Where these tokens are actually drawn, from the stylesheets:
+
+| Control | Rule | Rest | Hover / active | Focus |
+| --- | --- | --- | --- | --- |
+| Story composer | `.input-bar` (story.css) | `--border-bright` on `--bg-panel` | — | `--accent-dim` + `--accent-glow` ring |
+| Story controls | `.story-controls button` | `--border` on `--bg-panel` | `--border-bright` | (M11 focus check) |
+| Fields and buttons | `forms.css` | `--border` on `--bg-input` | `--accent-dim` | `--accent-dim` + ring |
+| Panel tabs | `.panel-tabs button` | **`transparent`** | `--border` on hover, `--border-bright` when active | — |
+| Top navigation | `.topnav` | `--border` bottom edge on **`--bg-panel-glass`** | — | — |
+| Scrollbar thumb | `base.css` | `--border-bright` as a *fill* on `--bg` | `--accent-dim` | — |
+
+Two of these cannot be answered by token arithmetic at all, and both are
+measured in the browser instead (§G): the nav sits on a translucent panel, and
+the panel tab's edge is `transparent` until the panel is open.
+
+---
+
+## E. The audit is now a gate
+
+`tools/contrast_audit.py`:
+
+1. **Boundary pairs fail.** `text` and `boundary` rows are both pass/fail; the
+   advisory branch is gone. The run returns 1 if either kind falls short.
+2. **Eight boundary pairs replace two.** Each border is checked against every
+   background it is drawn on — `--bg-input`, `--bg-panel` and `--bg` — plus the
+   focused edge (`--accent-dim`) on both panel and field backgrounds.
+3. **The verdict is taken on the number that is printed** (rounded to two
+   decimals), so a pair shown as `3.00:1` is not failed for arithmetic the
+   reader cannot see.
+4. The comment block that argued the old position is replaced by one recording
+   what changed and why, including why `--bg-panel-glass` is not in the list.
+
+## F. Gate tests
+
+`backend/tests/test_v11_e_contrast.py` — **11 passed**. The threshold is
+exercised from both sides, on real token files:
+
+| Test | Result |
+| --- | --- |
+| A boundary at **2.99:1** against `--bg-input` fails the run (exit 1) | PASS |
+| A boundary at **3.00:1** passes (exit 0) | PASS |
+| The **v1.0.0 value** `#2b2b3d` fails, at 1.24:1 against `--bg-input` | PASS |
+| A dimmed `--text-dim` still fails as a *text* pair | PASS |
+| A renamed token is a failure, not a silent skip | PASS |
+| The shipped palette passes both criteria | PASS |
+| Every boundary pair is measured against the background it is drawn on | PASS |
+| The M11 text baselines are unchanged: 14.57 / 13.57 / 5.48 / 5.88 | PASS |
+| The hover edge stays brighter than the resting edge | PASS |
+| No boundary becomes as loud as body text | PASS |
+| The WCAG ratio formula is anchored on known values (21:1, 1:1, symmetry) | PASS |
+
+The 2.99 and 3.00 values are worth noting: **both clear 3:1 against
+`--bg-panel`** (3.21 and 3.22). They decide the gate only because the floor is
+now taken against the background the control is really on — so these two tests
+also prove §C's change is doing work.
+
+---
+
+## G. Browser measurement
+
+`tools/m11_browser.py` gains a third suite, **WP-E**, counted separately from
+M11's 38 and WP-C's 53. It measures the *rendered* edge — `borderColor` from
+`getComputedStyle` — against what is actually behind it, with every translucent
+layer composited bottom-up.
+
+A boundary is measured against **both** adjacent colours (the control's own fill
+inside it, the background outside it) and passes on the better of the two: an
+edge that matches its fill but contrasts with the page is still a visible
+outline. What 1.4.11 asks is that the component's extent be perceivable.
+
+Two harness capabilities were added for this (`tools/m11_webdriver.py`):
+
+- **`hover()`** moves a real pointer through the WebDriver Actions API.
+  Dispatching a `mouseover` event from JavaScript does *not* trigger CSS
+  `:hover`, so a synthetic event would have re-measured the resting edge and
+  reported it as the hover edge.
+- **`screenshot()`** writes the viewport as a PNG, for the before/after evidence.
+
+**A defect this found in my own first measurement.** The first run reported the
+hover edge as `rgb(114, 114, 160)` and the focused edge as `rgb(144, 120, 81)` —
+neither of which is any token. Both controls carry `transition: border-color
+0.15s`, so the measurement was taken mid-animation, on a colour no state
+actually has. `_settled()` now polls until the computed edge colour is the same
+on two consecutive reads before measuring (polled, not slept, per this harness's
+own rule). After the fix the same edges read exactly `rgb(122, 122, 170)`
+(`--border-bright`) and `rgb(150, 119, 58)` (`--accent-dim`).
+
+---
+
+## H. Before and after, measured in the browser
+
+Both passes were taken the same way — `--only boundaries --no-narrator`, the
+production build — with only `tokens.css` differing. Evidence under
+`$HOME/v11-evidence/wp-e/before/` and `.../after/`.
+
+| Control (state) | Before | After | Floor |
+| --- | --- | --- | --- |
+| Story composer — resting edge | **1.88:1** FAIL | **4.88:1** pass | 3.0 |
+| Story control — resting edge | **1.43:1** FAIL | **3.70:1** pass | 3.0 |
+| Open panel tab — resting edge | **1.75:1** FAIL | **4.55:1** pass | 3.0 |
+| Story control — hover edge | **1.88:1** FAIL | **4.88:1** pass | 3.0 |
+| Top navigation — translucent edge | **1.43:1** FAIL | **3.70:1** pass | 3.0 |
+| Story composer — focused edge | 4.70:1 pass | 4.70:1 pass | 3.0 |
+
+**Suite result: before 5 passed / 5 failed; after 10 passed / 0 failed / 0
+skipped.**
+
+Two things this table says that a summary would blur:
+
+- **Focus was never the defect.** The focused edge (`--accent-dim`) already
+  cleared 3:1 in v1.0.0 at 4.70:1, and WP-E did not change it. What failed was
+  rest and hover — the states a reader spends all their time in.
+- **The translucent edge is real evidence.** The nav's background composited to
+  `rgb(17, 17, 29)` — `--bg-panel-glass` (rgba 19,19,32 @ 0.82) over
+  `rgb(10, 10, 15)` — not a fallback. That is the case token arithmetic cannot
+  reach, and it moved from 1.43:1 to 3.70:1.
+
+## I. Screenshots
+
+| File | |
+| --- | --- |
+| `before/control-boundaries.png` | 131,175 bytes, 1366×682 |
+| `before/control-boundaries-nav.png` | 63,376 bytes, 1366×682 |
+| `after/control-boundaries.png` | 132,430 bytes, 1366×682 |
+| `after/control-boundaries-nav.png` | 63,541 bytes, 1366×682 |
+
+All four are PNG, 1366×682, taken on the production build through the same
+harness path, differing only in `tokens.css`. The play-page pair shows the
+composer, the story controls and the open panel tab; the nav pair shows the
+translucent top edge on the library route.
+
+## J. A finding this package created and fixed
+
+Raising `--border-bright` broke something that had nothing to do with control
+boundaries. `.slice-7` in the context inspector's token breakdown was painted
+with `var(--border-bright)`, so it followed the token to `#7a7aaa` — an OKLab ΔE
+of **0.035** from `.slice-6` (`#7c86b8`), making two neighbouring chart slices
+effectively the same colour. The other slices sit **0.100–0.119** from their
+nearest neighbour.
+
+`.slice-7` is now pinned to `#3d3d55`, the literal value it already rendered, so
+its appearance is unchanged from v1.0.0 and its separation (ΔE **0.251**) is the
+widest in the set. A chart fill and a control edge have different jobs and should
+not share a token.
+
+Reassigning it to a fresh hue was considered and rejected on evidence: inside the
+palette's own chroma (0.045–0.120) and lightness (0.586–0.804) bands, the only
+hues clearing the set's 0.100 separation floor are pinks near 14°, which is
+`--danger`'s territory. Painting an ordinary prompt section in the colour this
+application reserves for failure would trade an accessibility fix for a semantic
+lie.
+
+*(A first attempt, `#5d7f9e`, was rejected by the same measurement at ΔE 0.061 —
+below every real slice. It is recorded here because it was written into the file
+before it was measured.)*
+
+## K. Text contrast regression
+
+Unchanged, and asserted so in §F: **14.57:1** body text on the page, **13.57:1**
+in a panel, **5.48:1** secondary text in a panel, **5.88:1** on the page. Every
+text pair still clears 1.4.3, and no text token was touched.
+
+## L. Browser release regression
+
+The full harness, all three suites, against a real narrator on the production
+build. Evidence: `$HOME/v11-evidence/wp-e/release/browser-report.json`.
+
+| | |
+| --- | --- |
+| Kind | **`release regression`** — not `partial`, not `development (only …)` |
+| Narrator | `qwen2.5:3b-instruct`, the reference model, over plain HTTP on the LAN GPU host |
+| Browser | Firefox 155.0.1, geckodriver 0.37.1 |
+| Served | FastAPI on loopback, the **built** SPA (`dist` 2026-09-15T21:08:52) |
+| Duration | 71 s |
+| Turns played | **8**, of which `turns_not_clean` **0** and `protocol_shapes_in_narration` **0** |
+
+**Counted per suite, as the brief requires:**
+
+| Suite | Passed | Failed | Skipped |
+| --- | --- | --- | --- |
+| **M11** (the v1 release regression) | **38** | **0** | **0** |
+| **WP-C** (browser release coverage) | **53** | **0** | **0** |
+| **WP-E** (control boundaries) | **10** | **0** | **0** |
+| **Total** | **101** | **0** | **0** |
+
+M11's 38 and WP-C's 53 are unchanged in count and in name: WP-E added a suite
+beside them rather than altering either. The `kind` field is quoted above
+because a fast run invites the question — 71 s for 101 checks including 8
+narrated turns is the GPU host being quick with a 3B model, and the 8 recorded
+turns with no unclean accounting are what rule out narration having been
+skipped.
+
+The WP-E rows in this run are the same ten as the standalone capture in §H,
+re-measured with a narrator present and a full story on the page.
+
+## M. Full regression
+
+| Suite | Result |
+| --- | --- |
+| **Full backend suite** (`pytest -q`, no `AIDND_TEST_*` set) | **1,723 passed, 17 skipped, 0 failed, 0 xfailed** (1,054.7 s) |
+| **Frontend suite** (`npm test`) | **175 passed**, 15 files, 0 failed |
+| **Lint** (`npm run lint`, oxlint) | **exit 0**, 0 errors, 15 warnings |
+| **Production build** (`npm run build`) | succeeded |
+| **Browser harness** (M11 + WP-C + WP-E) | **101 passed, 0 failed, 0 skipped** (§L) |
+| **Contrast audit** (`python tools/contrast_audit.py`) | **exit 0** — every text pair and every boundary pair passes |
+
+**The backend count reconciles exactly.** WP-D's tree was 1,712; WP-E adds the
+11 in `test_v11_e_contrast.py`. 1,712 + 11 = **1,723**. The 17 skips are the same
+environment-gated real-model tests recorded since B.1 — WP-E used no model and
+added no skip.
+
+**The plan's regression requirements for WP-E** were the frontend suite and
+lint, and the harness's accessibility checks. All three pass: 175 and exit 0
+above, and M11's `A11y` rows — accessible names, visible keyboard focus, no
+positive tabindex, nothing revealed only on hover, and the four rendered text
+contrasts — are inside the 38/38 in §L.
+
+**Lint detail.** The 15 warnings are the same pre-existing
+`only-export-components` and unused-import kind recorded at WP-C and WP-D, and
+**none is in a file WP-E changed**. `tokens.css` and `context.css` are not
+flagged.
+
+## N. Residual risks
+
+1. **The screenshots are unapproved.** The measurements say every boundary now
+   clears 3:1; whether the result *looks* right in this design is a judgment
+   the numbers cannot make. Recorded as PENDING in §O, not assumed.
+2. **Five controls are measured in the browser; the rest inherit.** The audit
+   checks token pairs, and the harness measures the composer, a story control,
+   the open panel tab, the nav edge and the focused composer. Every other
+   bordered surface — modals, cards, the knowledge and context panels — draws
+   the same two tokens, so it moves with them, but none is individually
+   measured. A component that overrides a border with a literal colour would
+   not be caught by either check.
+3. **`--bg-panel-glass` is outside the token audit by nature.** It is rgba over
+   a gradient, so no token pair can express it; its edge is covered only by the
+   browser measurement, which runs in the harness rather than in CI.
+4. **Disabled controls are deliberately not measured.** `.story-controls
+   button:disabled` carries `opacity: 0.35`, so a disabled control's rendered
+   edge is dimmer than any value here. WCAG 1.4.11 exempts inactive components,
+   and the harness selects `:not(:disabled)` on purpose — stated so that the
+   exclusion is visible rather than looking like an oversight.
+5. **The chart set was re-checked only where WP-E disturbed it.** `.slice-7`'s
+   separation and colour-blind distance were measured against the other seven
+   (§J); the set as a whole was not re-audited, which is outside this package.
+6. **`a11y.test.jsx` was not extended**, though the plan listed it as likely
+   affected. It asserts structure and names, not colours, and adding colour
+   assertions in jsdom would test the stylesheet's text rather than a rendered
+   result. Boundary contrast is asserted instead where it can be measured: the
+   gate tests (§F) and the browser (§G).
+
+**One risk that turned out not to exist.** §G's rule — a boundary passes on the
+better of its two adjacent colours — was written to avoid failing an edge that
+contrasts with the page but matches its own fill. In the event it never did any
+work: every measured boundary clears 3:1 against **both** neighbours (composer
+4.55/4.88, story control 3.44/3.70, panel tab 4.24/4.55, hover 4.55/4.88, focus
+4.38/4.70, nav 3.51/3.70). The stricter reading would have produced the same
+verdict on every row.
+
+## O. Final decision
+
+**Against the plan's acceptance criteria** (§ WP-E, *Control-boundary contrast*):
+
+| # | Criterion | Verdict |
+| --- | --- | --- |
+| 1 | `tools.contrast_audit` exits non-zero on any boundary pair below 3:1, and 0 on the package tree | **PASS** — 2.99:1 exits 1 and 3.00:1 exits 0 (§F); the v1.0.0 value exits 1; the package tree exits 0 |
+| 2 | Every text pair still clears 4.5:1, and the rendered text contrasts do not fall below v1's 14.57 / 5.48 / 13.57 / 5.88 | **PASS** — asserted as exact baselines in §F and re-measured on the rendered page in §L's M11 rows. No text token changed |
+| 3 | The rendered boundary of the story input and of a primary control, at rest and on hover, is at least 3:1; the focus indicator is still visible | **PASS** — composer 4.88:1, story control 3.70:1 at rest and 4.88:1 on hover (§H), and M11's visible-focus check passes in §L |
+| 4 | The owner approves the before-and-after screenshots, and the report records the approval | **PENDING** — not a criterion I can satisfy. The four PNGs are in §I |
+
+**Where I exceeded the criterion, said plainly.** The plan asks for 3:1 "against
+their panel" and names two controls. This package measures against
+**`--bg-input`** as well — the lighter background inputs and buttons are really
+drawn on, and the one that decides the gate — and adds the open panel tab, the
+translucent navigation edge and the focused state. The stricter floor is the
+reason the two threshold tests in §F are decided by `--bg-input` rather than
+`--bg-panel`, where both would have passed.
+
+**What I got wrong and corrected.** Three of my own claims failed checking and
+were fixed rather than softened: the first hover and focus measurements were
+taken mid-transition and reported colours no state has (§G); two contrast
+figures were written into `context.css` before being measured, and were wrong
+(§J); and my first gate check reported the current tokens as failing because my
+harness crashed on a shallow path, not because of any contrast.
+
+**Not done, and not claimed:** owner approval (criterion 4), individual
+measurement of every bordered component (§N.2), and any palette work beyond the
+two boundary tokens and the one chart fill that borrowed from them.
+
+```text
+WP-E CONTRAST GATE: PASS
+WP-E BOUNDARY MEASUREMENT: PASS
+
+WP-E OVERALL:
+PASS, pending owner approval of the screenshots (criterion 4)
+```
+
+All WP-E changes are **staged and uncommitted**. No commit, no push, no tag.
+v1.1 release validation has not begun.
+
+```text
+OWNER SCREENSHOT APPROVAL: PENDING
+```
+
+The before/after screenshots in §I are the evidence for a change a reader judges
+by looking at it. The measurements say every boundary now clears 3:1; whether
+the result looks right in this design is the owner's call, and it is recorded as
+pending rather than assumed.
