Commit `66d8a69` on branch `editing`. `XmlTextRef::diff` comes from the `Text` trait it implements (`yrs` `src/types/text.rs:420`), returning `Vec<Diff<D>>` where `Diff` has `insert: Out` and `attributes: Option<Box<Attrs>>`. The brief's guessed signature and `Out::Any(Any::String(s))` match pattern were exactly correct — used verbatim, no fallback needed. Watched it fail first: `cargo test --test fragment` failed with `E0432: unresolved imports docs_core::fragment_html, docs_core::fragment_text` before `core/src/fragment.rs` existed (the test file's own import bugs — `Decode` trait, `XmlFragment` trait — were fixed in that same pass so the real missing-symbol error was visible). After implementing `core/src/fragment.rs` and wiring `core/src/lib.rs`: all 7 tests pass on first run, no assertions weakened. Full `.amadan/ci.d/10-gate`: exit 0. Required re-copying `internal/core/testdata/docs_core.wasm` from the fresh build (gate caught the stale artifact), now committed. Go steps needed `dangerouslyDisableSandbox` once for a sandbox-readonly build cache, unrelated to this change.

Spec verdict: **PASS**. Quality verdict: **APPROVED** (two low-severity, non-blocking findings). Findings (ranked): 1. Low — `core/src/fragment.rs` `node_text`: text sibling before a block inside an unknown wrapper merges with no separator (verified: produces `"orphanactual"`). Only reachable via hand-built Yjs updates outside ProseMirror's own schema; affects `fragment_text` only, not HTML. 2. Low — asymmetry: `fragment_html` preserves empty `<p></p>` blocks, `fragment_text` silently drops empty blocks entirely (untested by the shipped suite). 3. Informational — none of the 7 tests exercise `fragment_text` against nested list/heading structure, and `unknown_nodes_keep_their_text` only covers single-level nesting (I verified nested-unknown-wrapping-known manually; it works, just uncovered by committed tests). Verified via throwaway tests (written, run, then deleted — tree left clean, confirmed via `git status --porcelain`): hostile tag names (`"script"`), hostile attribute injection (`onerror`, `style`), and heading-level extremes (`0,99,-1,abc,"",300,6.5,1e9`) all produce valid escaped output with no wrapper leakage; `text_content` and existing wire fixtures are byte-identical in the diff. One line: **a crafted document cannot inject HTML** — tag names are matched against a closed literal set (unknown falls to no wrapper), no attribute is ever echoed into output, and all text content is routed through `escape()`.

(Note: `core.New` alone doesn't instantiate/check ABI — only `NewDoc`/rebuild do — so the brief's literal `TestABIVersionIsPinnedAtTwo` doesn't itself exercise the refusal; I checked it manually per the instructions.) - Rebuilt and committed `internal/core/testdata/docs_core.wasm` (496031 → 580941 bytes). - Full gate `.amadan/ci.d/10-gate` exits 0; `cargo test` (including `no_host_imports` under `DOCS_REQUIRE_WASM=1`) and `go test ./...` all pass.

Tree is clean (verified `git status --porcelain` empty; `.superpowers/` is gitignored). **Spec verdict: PASS.** ABI functions mirror the text pair exactly (error codes, bounds-check order, zero-length/invalid-handle behavior); version bumped consistently in the one place on each side; `HTML`/`htmlOn` mirror `Text`/`textOn` line-for-line including the retry-once-after-rebuild path. All verification commands pass; fresh `./scripts/build-wasm.sh` output is byte-identical (580941 bytes) to the committed artifact. **Quality verdict: PASS**, with one known debt (the vacuous test) still unresolved. **(a)** Confirmed by deleting the version check and re-running: `TestABIVersionIsPinnedAtTwo` still passes — genuinely vacuous. The proposed `var abiVersion` fix is the wrong shape: a mutable global only tests write risks corrupting a documented immutable contract for every later test in the same process if a test panics before restoring it (Go runs a package's tests in one binary). Better: extract `checkABIVersion(reported, want uint32) error` as a pure unexported function and unit-test it directly with arbitrary values — same coverage, no global mutation, no production-code compromise. **(b) REFUTED.** Measured three built variants: replacing `format!`/`write!` with static-str `match`/`push_str` made the binary **larger** (581177, 581280 vs 580941), not smaller. Stubbing `fragment_html` to `String::new()` (keeping the exports but removing all XmlFragment traversal) dropped it to 496616 — only 585 bytes over the pre-Task-2 baseline. The 85KB comes from `yrs`'s XML traversal/diff machinery (`children`, `get_attribute`, `diff`/`YChange`, XML `GetString`) becoming linker-reachable for the first time, not from `format!`. No fragment.rs change is warranted. Other findings: memory-safety pattern (bounds checks against wazero's actual linear memory) unchanged from `text_read` and correctly reused; cited `yrs` 0.23.5 `from_utf8_unchecked` sites verified real; `TestHandleHTMLRendersFragment` is a genuine, non-vacuous test.</result> <usage><subagent_tokens>90216</subagent_tokens><tool_uses>45</tool_uses><duration_ms>268314</duration_ms></usage> </task-notification>

Cases covered by `TestCheckABIVersion`/`TestCheckABIVersionErrorNamesBothNumbers`: equal (nil), reported lower, reported higher, reported zero, and the error text names both numbers exactly (`"core module reports ABI 5, host understands 2"`). Confirmed I watched it fail before the fix: stubbed `checkABIVersion` to always return `nil` (simulating the deleted check), ran the new tests, and 3 of 4 subtests plus the message test failed as expected; restored the real comparison and reran to green. Also kept `TestNewDocSucceedsAgainstTheCurrentModule` (calls `NewDoc`, which drives `instantiate`) so the extraction stays wired to something real, not just unit-tested in isolation. `.amadan/ci.d/10-gate` exits 0.</result> <usage><subagent_tokens>109010</subagent_tokens><tool_uses>19</tool_uses><duration_ms>158480</duration_ms></usage> </task-notification>

New tests `TestSeededDocumentsRenderAsHTML`/`TestWaterworksHistoryHasHeadings` pass. Three pre-existing tests asserted seeded content via `Store.Text`, which now legitimately reads empty (seed content moved to root "prosemirror"); moved them to `Store.HTML` and tightened `TestSeedContentMatchesItsSource` to also require real `<p>` markup rather than just non-empty text. **Rendered HTML** (Millbrook waterworks opening): ```html <p>A History of the Millbrook Waterworks</p><h2>Early years</h2><p>Before 1887, Millbrook drew its water the way most small towns did: from private wells, a handful of shared pumps on the main street...</p> ``` Five `<h2>`s render correctly (Early years, Construction and the first reservoir, Expansion through the early twentieth century, Modernization, The works today). **Honest read:** Signed in for real via magic link, screenshotted both the long and short documents in Chromium. It reads like a document — comfortable 6.5in measure, Georgia serif, headings clearly heavier without shouting, good rhythm between sections. Minor oddity (inherent to the brief's own classifier rule): the first paragraph repeats the title verbatim as body text right below the page's real `<h1>`, a bit redundant but working as specified.

The dev server process was killed and no fixture/source files were modified (fixture regeneration was verified in place and confirmed no diff). ## Summary **Spec verdict: PASS.** Every brief step delivered — `blocksFor` in `fixtures/generate-seed.mjs`, `Store.HTML` mirroring `Store.Text`, `handlers.go`/`show.html` wired to it, both test suites and the gate green, fixtures byte-reproducible with `clientID = 1` pinned. Confirmed live via a real magic-link sign-in and HTML fetch. **Quality verdict: PASS, with two real gaps** worth a follow-up commit — the known title-repeat defect, and `Store.Text` left as a silent trap. **Recommended fix for title repetition:** drop the seed generator's first block only when it equals the document's `Title`, in `fixtures/generate-seed.mjs` — not unconditionally, and not in the template. Proof: `letter.txt`'s first line ("Dear Members of the Harbourview Allotment Committee,") is real content, not a title echo, and I confirmed live that the letter document does *not* show the bug today — an unconditional drop would silently delete that line. A template-side fix would also leave the duplicated title sitting in `Store.Text`/`fragment_text` output for any future consumer (list preview, search). Ranked findings (full detail in the review file): 1. `internal/docs/store.go:385-401`, `internal/docs/models.go:30` — `Store.Text` now has zero production callers (confirmed by repo-wide grep); it reads a different CRDT root (`"content"` `Y.Text`) than every real document now uses (`"prosemirror"` fragment, per Task 1), so it silently returns `""` for anything real, and neither its own doc comment nor `models.go`'s pointer to it was updated. 2. `internal/docs/seed_test.go:29-49,127-224`, `internal/docs/sample_documents_test.go:60-73` — only `TestSeedContentMatchesItsSource` was genuinely tightened (new `<p>` assertion); the other two were swapped `Text`→`HTML` at unchanged strength, despite the report's blanket "tightening" claim. None are vacuous. 3. Escaping/`template.HTML` — no bypass found; `core/src/fragment.rs` escapes all text, emits no attributes, and `Store.HTML` is the sole construction site. 4. Fixture reproducibility — confirmed clean across two regenerations. 5. Template comments/structure/`docs-*` vocabulary — all intact, no `class="rst-*"`. 6. Live render — matches the known defect on 5/6 documents exactly as predicted; the letter is the exception, and nothing else looked wrong.

Commit `a7795e1` on branch `editing`. **Letter's first block now:** `<paragraph>Dear Members of the Harbourview Allotment Committee,</paragraph>` — verified directly against the regenerated `.bin` (not assumed); `letter.update.bin` is byte-identical to before (absent from `git status`), so this is the pre-existing correct behavior, untouched. **Store.Text test:** Added `TestSeedTextReturnsRealProse`, watched it fail first: `Text = "", want it to contain the packing list's real opening line`. Then repointed `text_string` (abi.rs) to `fragment_text`, no ABI bump, with the "why" documented at the function. **Test results:** `go test ./...` and `.amadan/ci.d/10-gate` both green (exit 0), including Rust (`fragment.rs`, `wire_compat.rs`, `wasm_trap_containment.rs`) and Go suites. Repointing broke other tests reading `fixtures/data` (Y.Text) through `Text`/`(*Handle).Text`; added `fixtures/vectors/fragment/{hello,unicode,formatted,concurrent}` and repointed those tests, leaving `TestSlowUpdateIsCutOffByGuestCallTimeout`'s pinned RNG-mutation reproducer untouched on the old fixtures. Also corrected the earlier report's overbroad "tightened" claim — narrowed to the one test (`TestSeedContentMatchesItsSource`) that actually was.</result> <usage><subagent_tokens>263199</subagent_tokens><tool_uses>78</tool_uses><duration_ms>798303</duration_ms></usage> </task-notification>

Full review written to `.superpowers/sdd/2026-08-31-editing/task-3-rereview.md`. **Both findings genuinely fixed.** Finding 1: `blocksFor` in `fixtures/generate-seed.mjs` now drops the first block only on exact trimmed match against a `titles` map — verified by decoding the regenerated `.update.bin` bytes directly: 5/6 docs drop their title-echo, `letter.txt` still opens with its real salutation. Finding 2: `core/src/abi.rs::text_string` now calls `fragment_text` (root "prosemirror"); `text_content` is untouched and still backs the wire-compat Y.Text tests. **Repointed tests — all kept strength, none weakened:** - `wasm_trap_containment.rs` (both tests) — kept; the hardcoded trap-repro hex is independent of the fixture-dir swap, ran live and still reproduces `MemoryOutOfBounds`. - `wire_compat.rs::abi_round_trips_a_fixture` — kept (uses pre-existing `simple.bin`). - `TestTrappedInstanceIsDiscardedAndRebuilds` — kept. - `TestSlowUpdateIsCutOffByGuestCallTimeout` — correctly left on `fixtures/data` for its RNG-mutation loop; ran live, still reproduces the pathological ~4.3s decode, cut off at 1s cap. - `TestAppliesFixturesUnderWazero` + `TestGarbageUpdateReturnsErrorNotTrap` — kept; concurrent still tests a genuine two-client conflict merge (block-level analogue of the old char-run merge), formatted arguably tightened (now also checks the format attribute name decoded correctly). - `store_test.go`'s two repointed tests — kept. **Fixture reproducibility:** confirmed — regenerated both `generate-fragment.mjs` and `generate-seed.mjs` twice, `git status` stayed clean each time, byte counts identical. **Verification:** `cargo test` (16/16), `go test ./...` (all pass), `.amadan/ci.d/10-gate` (full green, one benign sandbox artifact from `go build`'s module cache that didn't stop the gate). Tree left clean. **Nothing else broken.** `Store.Text`/`HTML` doc comments in `store.go` were already root-agnostic and needed no update; `TestApplyLogCapFailsCleanly` correctly stayed on the old fixture since it asserts rejection, not content.</result> <usage><subagent_tokens>114727</subagent_tokens><tool_uses>42</tool_uses><duration_ms>367573</duration_ms></usage> </task-notification>

Implemented `internal/docs/assets.go` + wired into `app.go`'s `/static/*` route; both tests then pass. **Test results:** full `internal/docs` package ok (9.2s); `.amadan/ci.d/10-gate` exit 0. **One necessary deviation:** Go's `//go:embed` can't cross `..`, so the committed tree lives at `internal/docs/static/` (not a top-level `static/` as the brief's file list literally suggested) — same pattern as the existing `internal/docs/views/`. Also wrote the anonymous-request test with `httptest.NewRequest` + `app.Handler().ServeHTTP` directly rather than the brief's literal `app.TestRequest(t, "", ...)`, since `TestRequest` always signs someone in and has no empty-address special case. **CI gate gap:** it already runs `npm ci` and `go test ./...`, which exercises the new deps and embedded bundle automatically — no change needed there. It does *not* verify the committed bundle matches a fresh `node build-editor.mjs` build, unlike the analogous wasm freshness check for `core/`. Flagged in the full report but not added, since it's outside Task 4's specified steps.

No sourcemaps, banners, timestamps, or absolute paths found in script or output (`grep sourceMappingURL`/`/home/paulca` → 0 hits). esbuild's actual work runs in a pinned-version (`0.28.2`) native binary, not Node-interpreted JS, so Node version is irrelevant; a CI freshness check only needs one fixed runner to agree with itself, which is weaker than cross-machine reproducibility and already demonstrated. **Recommendation: (a)** — add the full freshness check to `.amadan/ci.d/10-gate`, mirroring the wasm check (rebuild + `git diff --quiet -- internal/docs/static/`). No nondeterminism found; the risk (Task 6 edits the entry point) is live and the fix is cheap. Findings (ranked, all confirmed by direct testing, not just reading): 1. Anonymous serving confirmed live via real `httptest.NewServer` + anonymous `http.Get`: 200, correct content-type/cache-control, route registered in `internal/docs/app.go:435` above the `RequireSession` group. `assets_test.go`'s `TestEditorBundleIsServed` genuinely uses an unauthenticated request path. 2. Caching hash provably computed over served bytes (`internal/docs/assets.go:75-89`); 0/2+ bundle case panics at init with an actionable message (`assets.go:44-58`). 3. All deps pinned exact, from npmjs.org, `yjs` unchanged at `13.6.27`; only expected transitives present. 4. `go:embed` relocation to `internal/docs/static/` confirmed necessary; no stray top-level `static/` references anywhere. 5. Both new tests are non-vacuous — each assertion fails under the corresponding defect. 6. Gate gap (no bundle freshness check) is real and pre-existing per the brief, but should be closed before Task 6 — see recommendation (a).

Commit `d1d0884` on branch `editing`. `.amadan/ci.d/10-gate` exits 0. Implemented `GET /d/{sqid}/updates` (streams the concatenated update log, owner-scoped, capped at `maxLogBytes = 8<<20`, fails loudly with a logged sqid on overflow rather than truncating) and `POST /d/{sqid}/updates` (wraps the body in `http.MaxBytesReader` at `maxUpdateBytes = 1<<20` before reading, applies via `Store.ApplyUpdate`, maps any core rejection to 400 without persisting). Both use `Store.Get`'s existing 404-not-403 owner scoping. CSRF origin-checking is not exempted for the route. **Owner-scoping verification**: ran the four tests before routes existed — the scoping test passed for the wrong reason (unrouted 404), the other three failed correctly. Wired the routes, then temporarily patched `getDocumentForUpdates` to bypass ownership (raw sqid-only lookup); reran the scoping test and it failed for real (`200`/`204` instead of `404`). Reverted to the real `Store.Get(ctx, owner, sqid)` implementation (diffed byte-identical against my backup before committing) and it passed. **Parked Task 1 findings**, fixed in `core/src/fragment.rs`'s `node_text`: (a) a text sibling preceding a block now gets flushed before the block consumes its own children, so `"orphanactual"` becomes `"orphan\n\nactual"`; (b) an empty `<p></p>` now leaves a blank text segment (matching `fragment_html`) instead of vanishing, distinguished from a block whose child already flushed via a `had_children` guard so nested blocks (e.g. `list_item > paragraph`) don't gain spurious empty entries. Three new Rust tests cover this, all passing. Test results: `go test ./...` green; `cargo test` (core, 19 tests) green; full CI gate green, including the wasm-freshness check (re-copied `internal/core/testdata/docs_core.wasm`) and the JS/Rust wire-compat round trip.

Verified by doing: `go test ./...` green, `cargo test` green (incl. 3 new fragment tests), `.amadan/ci.d/10-gate` exit 0. Confirmed `yrs` `from_utf8_unchecked` at `read.rs:137`. Hostile POSTs (driven through the real router): empty body, truncated (½ and 1 byte), huge-length varint, 64×`0xff`, single `0x00` → all **400, none persisted**. Valid foreign-client update and real `nested.bin`/`marks.bin` → 204. **Exhaustive single-byte flip of `simple.bin` (291 flips): 194 accepted / 97 rejected, 0 read-errors and 0 HTML-errors after any accept.** One flip triggered a genuine trap in `yrs` (`panic_const_div_by_zero` in `block_store::find_pivot` from `docs_core_apply`) — **contained**: instance discarded+rebuilt, 400 returned, nothing persisted, document readable, no hang (whole sweep 4.1s). Also confirmed: injected >8MB log → GET returns **500 + 19-byte error page, not a truncated log**; `MaxBytesReader` wraps before `io.ReadAll` (413 before buffering); guest-call 1s timeout + `WithCloseOnContextDone` on the POST path. Owner scoping is **not vacuous** — I neutralised `owned()` and `TestUpdatesEndpointsAreOwnerScoped` failed for real (stranger GET=200/POST=204). The `had_children` guard is correct across all three fragment cases; tests use discriminating exact-string asserts. Findings: - **LOW-1** — `store.go` `ApplyUpdate` (~485-505) + `migrations/0001`: no `UNIQUE(doc_id, seq)` and non-atomic `MAX(seq)`→INSERT. Task 5 first exposes `ApplyUpdate` to concurrency; simultaneous POSTs to one doc can write duplicate seqs. Harmless (CRDT convergence, per-request instance) but the invariant is unenforced. - **LOW-2** — `handlers.go` `updatesPost`: all `ApplyUpdate` errors collapse to 400 + Info log, so a real rebuild-failure or DB error is mis-reported as "bad update" and under-logged. Split clean-rejection/`Recovered` (400) from other errors (500 + Error). - **INFO** — 8MB doc → 500 on GET for the owner; loud-not-silent, the intended D2 behaviour pending compaction.

Commit `f1be04a` on branch `editing` (fix round 1, on top of `d1d0884`). `.amadan/ci.d/10-gate` exits 0. **(1) 400/500 classification** — `internal/core/core.go` gains `RejectedError`/`Rejected(err)` mirroring the existing `RecoveredError`/`Recovered(err)`. `store.go`'s `ApplyUpdate` wraps only the *new* update's `h.Apply` error in an unexported `*updateRejection` (a replay failure calls the same `core.Handle.Apply` and would otherwise be indistinguishable). `handlers.go` requires that wrapper *and* `Recovered`/`Rejected`/`ErrUpdateLogFull` before returning 400/Info; everything else is 500/Error with the doc id. Induced a real 500 (`TestInternalApplyFailureReturns500NotBadUpdate`) by writing a garbage row directly into `doc_updates` so the next POST's replay genuinely fails through the real wasm core — no mock. **(2) seq race** — chose "compute and insert inside one transaction" over retry-on-collision: `rastrillo/db`'s write pool caps at one SQLite connection, so `gorm.DB.Transaction` makes a racing request block on `Begin` until the first commits, closing the race by queuing rather than racing-and-retrying. Verified this matters: a bounded 5-attempt retry-loop version I built first genuinely exhausted its budget and returned real 500s under a 21-goroutine race, while the transaction version passed 15/15 clean runs. Added `UNIQUE(doc_id, seq)` (migration `0003`) as a backstop, safe to apply as-is since no live database was ever exposed to the vulnerable code. Confirmed `TestConcurrentUpdatesDoNotCollideOnSeq` fails against the pre-fix two-statement code: reverted locally (never committed) and it failed 3/3 runs (rows going missing / genuine 500s) before the transaction fix, 15/15 clean after. One correction en route: my first race-test draft posted 7 different fixtures concurrently and hit real, unrelated core rejections, because every fixture pins the same `clientID` for reproducibility, making them structurally incompatible when layered together — switched to reposting one fixture N times instead.

Implemented the ProseMirror editor per the brief (`fixtures/editor-entry.js`), added the `docs-editor`/`data-sqid` mount point and script tag to `internal/docs/views/show.html`, wired `Sqid`/`EditorScript` through `handlers.go`'s `showPage`, and added `internal/docs/editor_view_test.go` (failing first, then passing). While actually exercising the running app (per Step 6), found and fixed two real bugs that the green test suite never caught: 1. `new EditorView(el, {state})` **appends** a sibling DOM node instead of replacing `el`'s contents — fixed with `{mount: el}`. 2. `GET /d/{sqid}/updates` returns a raw, unframed concatenation of per-POST Yjs updates; a single `Y.applyUpdate` call silently decodes only the first message, so a second edit vanished on reload. Proved this in isolation with real `yjs` first, then fixed by looping `Y.readUpdate` over one `lib0/decoding` decoder until exhausted (added `lib0` as an explicit fixtures dependency). Verified in a real Playwright-driven browser session (real magic-link sign-in): typed a sentinel sentence into a seeded document, waited past the debounce, reloaded, and confirmed the text persisted. Then confirmed with plain `curl` (no JS at all) that the same edit renders server-side, with exactly one `docs-editor` mount point referencing the committed bundle.

Full review: `/home/paulca/amadan.net/carlos/docs/.superpowers/sdd/2026-08-31-editing/final-review.md`. **What I did in the browser** (real Chromium, real magic-link sign-in, dev server on 8177): two separate edits with reload — both persisted (the fixed decode bug stays fixed); edit → reload → edit with a fresh Y.Doc client → all persisted; rapid typing across five debounce windows — all persisted; navigate-away inside the 400ms window — the beacon really carried the bytes; one aborted POST — requeue/retry recovered; a persisted-but-client-saw-failure resend — idempotent, content once. Then plain `curl`: the server-rendered page contains the browser-made edits verbatim (§6.2 holds for edited documents), and CSRF probes got 403. `go test ./...`, `cargo test` (DOCS_REQUIRE_WASM=1), and `10-gate` all green; tree left clean, server stopped. **Findings:** 1. **HIGH, reproduced — F1**: `fixtures/editor-entry.js:88-97` requeues any `!r.ok` flush and merges later edits into the poisoned batch. A ~1.2MB paste → 413 → observed `413,413,413` for every later edit → after reload the paste **and both later small edits were gone**, silently. Same sibling class as the decode bug; violates the file's own "never lose an edit silently" invariant. Not BLOCKING only because it needs a >1MB single flush and loses nothing until tab close; fix is ~5 lines (don't retry 4xx / don't merge a rejected batch). 2. **MEDIUM — F2**: `data-save-failed` has no CSS and no catalog copy — save failure is invisible (plan-authored). 3. **MEDIUM — F3**: one row per 400ms flush makes the core's 4096-update cap (`internal/core/core.go:103`) reachable in ordinary sustained use; hitting it is a permanent per-document F1 wedge. §4.1 snapshots just became time-sensitive. 4. **LOW**: in-flight flush bytes aren't beaconed at unload, and `sendBeacon`'s return is ignored (~64KB quota); `Store.ApplyUpdate`'s owner re-check (`store.go:494`) doesn't filter `deleted_at` (unreachable today). No cross-task drift (root `"prosemirror"` consistent; the ABI text repoint chased through every caller; D1–D5 all honoured; no vacuous tests found in the branch's additions). **Security composes**: every path to the CRDT passes session → origin-check (verified 403) → owner-scoped 404 → size cap → DB-re-derived ownership → wasm-sandboxed yrs, with escaping done once in Rust against a fixed allowlist emitting zero attributes — nothing opens what another layer closed.</result> <usage><subagent_tokens>172221</subagent_tokens><tool_uses>56</tool_uses><duration_ms>576454</duration_ms></usage> </task-notification>

Copy anything important before leaving this page." once a batch is permanently dropped. Also found and fixed, via the coordinator's own required ">1MB paste, reload" check (not in the reviewer's list): dropping a batch left the local Y.Doc diverged, silently poisoning *every* later edit (204 returned, but never actually integrated server-side — confirmed in isolation with real yjs). Fixed with `resync()`: on permanent rejection, discard the diverged doc/view and rebuild from a fresh server fetch.

Verdict: **F1 HOLDS** — gate ok, 3/3 node tests, `go test ./...` ok; live: 1.2MB paste got one 413, was never re-POSTed, next edit POSTed alone (204) and survived reload. **F2 HOLDS** — indicator appeared with exact catalog copy for both states (failed sticky across later saves; retrying cleared after a network blip recovered). **F3 HOLDS** — 4096×2s = 2h16m and 4096×400ms ≈ 27min both check out; the unload tradeoff was considered (pendingBytes covers in-flight; beacon-refusal fallback added). **Resync HOLDS on the happy path, BROKEN on its own error path** (below). In the browser (real Chromium via playwright-core against `run-dev.sh`, signed in by magic link): typed, pasted 1.2MB, saw the failed indicator, typed after, reloaded — later text survived, paste gone. Then aborted the resync GET at the drop moment: resync failed once, and everything typed afterwards got **real 204s (315B, 259B) and vanished on reload**. Findings: 1. **BLOCKING** — fixtures/editor-entry.js:175 (resync catch): "another chance the next time a batch is dropped" is false — poisoned edits 204, never 4xx, so resync is never retried; one transient failure recreates the silent-204 loss for the whole session, and the failed copy ("before leaving this page") steers the user to stay on the broken page when reload is the cure. Fix is small: retry resync from the catch / on `online`. 2. MEDIUM — render.go:130 failed copy tells the user to copy text resync already wiped from the screen (verified: paste gone from DOM before the indicator is readable). 3. MEDIUM — editor-entry.js beforeunload: keepalive fetch shares sendBeacon's 64KiB quota (verified: 100KB rejects, 30KB resolves) — the fallback cannot carry the paste-sized case its comment cites. 4. MEDIUM — core.go Apply/handlers.go updatesPost still 204 unintegratable updates; the class stays open server-side — name it in the §4.1 snapshot plan. 5. LOW — poisoned 204 rows permanently burn the 4096-row/8MB caps; LOW — resync loses cursor/focus; LOW — a full log becomes a drop→full-GET cycle every 2s. 6. NOTE — save-queue.test.mjs is real (stub matches fetch semantics), but nothing automated covers resync/sessionFailed/DOM wiring — tests pass with resync deleted.

Fixed by extracting retry logic into `fixtures/resync-controller.mjs` (exponential backoff 1s→30s cap, plus immediate retry on the `online` event), with `diverged` gating every local edit so nothing is sent (and no 204s wasted) while unrecovered. Re-ran the identical reproduction against the fix: the during-divergence edit is never even POSTed, the retry recovers within seconds, and a post-recovery edit survives reload. **New failed-state copy:** *"Some changes couldn't be saved and were lost. Reload the page if this keeps happening."* **Keepalive quota:** verified `fetch(..., {keepalive:true})` shares materially the same ~64KB limit as `sendBeacon` (100KB refused by both, 30KB through both) — it was never a real fallback for paste-sized payloads. Corrected the comment to say so honestly rather than claim coverage that doesn't exist; kept the fallback since it can still help when `sendBeacon`'s refusal was about the page's shared quota, not this payload's own size. Added `fixtures/resync-controller.test.mjs` (fake-clock, `node --test`, wired into the gate) covering drop→attempt→fail→retry→succeed and the `online` fast path; confirmed it fails for the right reason against the pre-fix logic first.</result> <usage><subagent_tokens>395887</subagent_tokens><tool_uses>36</tool_uses><duration_ms>641510</duration_ms></usage> </task-notification>
