Task 7's deploy bullet (`make release`, `carlos deploy`, canary walk, push, branch discussion) is untouched — that is the controller's. Commit: `526061d` — docs: slice 2 in AGENTS, README, PRODUCT, api.md; gate runs the JS toolchain (7 files, +671/−108, both trailers present, nothing pushed). Gate: green end to end on a clean `git archive HEAD` export (fresh `git init` so status/diff are meaningful) — `128 pass, 0 fail` node tests, 5 vectors regenerated clean, bundle rebuilt to the same `editor.d193d83bc4c2adaa.js`, `make ci` green, `gate: ok`, exit 0, export tree clean afterwards. Both new checks proven able to fail: a tampered vector (exit 1) and a renamed committed bundle (`D` + `??`, the stale-bundle message, exit 1, tree restored). Concerns: the vector-freshness step is largely redundant with `ops.test.mjs`, which fires first (the untracked half still earns it); `npm ci` now needs the npm registry at run time and whether the amadan runner reaches it is unverified; the gate has never run on the runner with these steps; `require_committed` uses a path-scoped `git clean -fdq` on its failure branch; and every claim in the docs comes from reading code and the six task reports, not from opening the editor.

The user can send it another message and resume it, so the same task-id may notify more than once.</note> <result>### Spec Compliance Task 7's first two bullets are implemented and match the brief. - **Gate** (`.amadan/ci.d/10-gate`): adds `node`/`npm` to the tool-check loop, `npm ci --cache "${NPM_CACHE:-$HOME/.npm}"` from `fixtures/`, `node --test *.test.mjs` (deliberately not `node --test fixtures/`, which Node 24 silently no-ops on), `node generate.mjs` + a freshness check on `fixtures/vectors`, `node build-bundles.mjs` + a freshness check on `internal/slides/static`, then `make ci` (which still runs the Go `vectors_test`). Order, `set -euo pipefail`, and the wasm `cmp` step are all unchanged and intact — verified by reading the full current script (`.amadan/ci.d/10-gate` lines 1–166). - **Docs**: `AGENTS.md`, `README.md`, `PRODUCT.md`, `docs/api.md` all rewritten to describe the editor, the live-sync wire, the fixtures rule, the bundle, the `href` ruling, the seams (`render.SlideWith`/`serveAsset`), what's not built, and the 503-without-a-store behavior. `.amadan/README.md` updated with the JS toolchain section and the `npm ci`-needs-registry trade-off. - Task 7's third bullet (`make release`, `carlos deploy`, canary walk, push, branch discussion) is explicitly and correctly left to the controller — the report says so plainly, and nothing in the diff claims it happened. ### Strengths - `require_committed()` is a clean, well-justified abstraction: it correctly explains *why* both `git diff --exit-code --name-status` and `git status --porcelain` are needed (a moved content hash produces a deletion **and** an untracked file — `git diff` alone misses half of it), and the report backs this with a concrete RED-run reproduction (renaming the committed bundle file) that shows exactly the failure mode the second check catches. - The report is unusually self-aware: it flags its own weak points (vector-check redundancy with `ops.test.mjs`, `npm ci` needing the registry, the gate never having run on the real runner, and the `git clean -fdq`) rather than hiding them. - Spot-checking a dozen factual claims against code found the documentation largely accurate: routes in `app.go`, `Slides-Seq`/`Slides-Snapshot` headers and 4-byte framing in `live.go`, 1 MiB update cap, SSE timings (15s ping / 5min TTL from `presentation.go`), presence heartbeat (20s, `fixtures/presence.mjs`) and two-missed-beats sweep (`live/hub.go`), `assets.go`'s 20 MiB cap and four allowed types, the editor's three panes and three-section inspector in `editor.html`, the `href` one-key-map shape in `core/src/schema.rs`, the 318-key catalog count (`grep -cE '^[A-Za-z0-9_.-]+ *=' internal/slides/locales/en.toml` reproduces exactly), and the "five vectors" claim (5 files in `fixtures/data/` and `fixtures/vectors/`) all check out. - No doc claims the editor was walked by hand in this task; the only "walks" references are to the automated `browser_test.go`, consistent with the report's honest disclosure that this task's docs came from reading code and prior reports, not from using the editor. ### Issues **Important** 1. **`require_committed`'s `git clean -fdq` is not clearly a data-loss warning, though it is narrowly scoped and largely justified.** It only runs on the failure branch, and only against the two directories being checked (`fixtures/vectors`, `internal/slides/static`), both of which are pure generated-and-committed output by design — nothing legitimate is meant to be hand-authored there. So in practice what gets deleted is either regenerable build output (the intended case) or a forbidden hand-edit to a vector (arguably correct to discard). The real gotcha: if a developer adds a new `fixtures/data/*.json` and runs the gate for the first time, `node generate.mjs` correctly produces the new vector files, the check sees them as untracked ("stale"), prints `gate: vectors are stale: run node fixtures/generate.mjs and commit` to stderr, and then **immediately deletes the very file the message told them to commit** before they can `git add` it. Re-running `generate.mjs` recovers it, but the sequence is confusing and worth a one-line fix (either mention explicitly that the check restores the directory, or reorder the message to say so). Not a blocker given the narrow scope, but it's the one named risk here that isn't fully resolved, only noted by the report's own concern #4. **Minor** 2. **`docs/api.md`'s refusal list for `POST /d/{sqid}/assets` is slightly wrong.** It lists `unsupported_type` as one of that endpoint's possible refusals (docs/api.md, "Refusals are..." under `### POST /d/{sqid}/assets`), but `registerAsset` (`internal/slides/assets.go` lines 268–360) never emits `unsupported_type` — that code belongs only to `signUpload` (line 165). A bad content type reaching `registerAsset` comes back as `not_an_image` (from `sniffImage`, line 328) instead. One word in an enumerated list; trivial fix. 3. **AGENTS.md's line-count claim is off by 19 lines.** "How the editor is put together" states "every other module under `fixtures/` is one concern and stays under 300 lines," but `fixtures/canvas.mjs` is 319 lines (`wc -l fixtures/canvas.mjs`). Either the claim needs qualifying (e.g., "close to 300") or the file needs trimming; as written it's factually false. ### Assessment **Needs fixes** — but the fixes are small and mechanical, not structural. The gate implementation itself is sound: step order, `set -euo pipefail`, the wasm `cmp`, and `NPM_CACHE` handling are all intact and correct, and the `require_committed` design is well-reasoned and proven against real failure scenarios. The documentation is substantially accurate on spot-check (10 of 12 checked claims verified exactly against code), but two concrete factual errors were found (the `unsupported_type` refusal misattribution and the false "under 300 lines" claim), and the one named safety risk the controller asked about — the failure-branch `git clean -fdq` — is acceptable in principle but not clearly communicated as a discard-on-failure behavior to a developer reading the printed message in the moment. None of these require redesign; they're a few lines each to correct before merge.</result> <usage><subagent_tokens>132208</subagent_tokens><tool_uses>36</tool_uses><duration_ms>266151</duration_ms></usage> </task-notification>

The user can send it another message and resume it, so the same task-id may notify more than once.</note> <result>I worked in four passes (server transport and integrity; core tolerance and CSRF; a poison-update experiment in a scratch copy plus a11y/docs/tests; canary probes), no subagents. Worktree untouched; the experiment ran in `/home/paulca/.cache/tmp/claude-1001/slides-scratch` and `/poison`. ### Summary Slice 2 lands the whole plan: the live-sync wire, hub, snapshots, the editor, inspector, canvas, switcher, presence, assets and the JS-aware gate, with real HTTP tests and a canary that answers the right unauthenticated shapes (`/api/version` → `526061d`; signed-out GETs 303 to `/signin`; POST/PUT without a session 403). One Critical stands: a member can POST a well-formed Yjs update whose values have the wrong *type* (a `box` with a string `x`, a `background.kind` number, a non-object `assets` entry, a non-string `fonts` field), the core accepts it, `commitUpdate` stores it, and from then on `openDeck` fails at `deck.Parse` for every surface and every write path — the deck is bricked with no path back short of DB surgery. Two Importants (snapshots are not cascaded on delete; a dropped 4xx batch is shown as "Offline, retrying") and a handful of small items round it out. ### Plan alignment All seven tasks are present and match the plan's Global Constraints: framing and `Slides-Seq` derived from the body (`live.go:113`), `Slides-Snapshot` at `since=0` only, SSE with `update`/`presence`/ping and the presentation stream's timings, snapshots at 200 by the crossing request after commit, presence in the hub only, 503 without a store, one bundle, Docs' three modules copied verbatim. Op vocabulary: `core/src/ops.rs` has 15 variants; `fixtures/ops-parse.mjs` has the same 15 cases; nothing on one side only. The browser builds no slide structure itself (`innerHTML` only receives server HTML in `stage.mjs:234` and `strip.mjs:125`; the rest is chrome — handles, avatars, list rows). Deviations, all rulinged or reported: `verify-rust.mjs` became `core/vectors_test.go` (equivalent, and the gate regenerates vectors); href map shape (row 12); fonts as CSS strings; the phone-override badge is in the inspector, not on the stage block (spec §3.2, Task 5 report); the "failed" status state the ledger deferred to Task 7 was not added. ### Findings **Critical** 1. **A poison update bricks a deck for everyone.** `commitUpdate` (`live.go:314-317`) only asks the core whether the bytes *apply*; it never asks whether the resulting view still parses. The Rust view is tolerant at the top level (`schema::maps_of`, `get_string` return defaults for wrong shapes) but passes `box`, `background`, `fonts`, `phone` and every `assets` entry through as whatever object is there (`view.rs:105,126,147,155`), and `deck.Parse` (`deck.go:173`) unmarshals into typed structs. Reproduced in the scratch copy with updates minted by the fixtures' own `yjs`: of 15 shapes, four brick — `box.x = "a"`, `background.kind = 5`, `fonts.body = []`, `assets.x = "str"` — each with `deck: parse view: json: cannot unmarshal …`. `openDeck` (`decks.go:192-221`) sits under the viewer, the editor, `deckSlide`, `serveAsset`, the API's `editDeck` **and** `appendUpdate` itself, so after the row commits nothing can render and nothing can write. Fix, two layers: (a) in `appendUpdate`, move `h.Apply` out of the transaction and follow it with `h.JSON` + `deck.Parse` *before* the insert, answering 422 (`errUpdateRefused`) on a parse failure — this costs no extra wasm call, because `mirrorMeta` (`live.go:389`) already does that read after commit; hand it the parsed view instead. (b) In `view.rs`, emit `box`/`background`/`fonts`/`phone` only when every field has the right type and skip `assets` entries that are not maps with a string `ref`, mirror that in `fixtures/view.mjs`, add a vector. Add `TestPoisonUpdateDoesNotBrickTheDeck` in `slidestest/live_test.go` posting the four shapes and asserting `GET /d/{sqid}` still 200s. The existing `TestRefusedUpdateIs422` only posts non-Yjs bytes. **Important** 2. **`deleteDeck` does not delete `deck_snapshots`** (`decks.go:1031-1047` deletes presentations, updates, grants, share links, the row). `decks.id` is `AUTOINCREMENT` (`0002_create_decks.sql`), so the orphan cannot be replayed into a reused id, but each orphan is a whole copy of a deleted deck kept forever. One more `tx.Where("deck_id = ?", d.ID).Delete(&amp;DeckSnapshot{})` and an assertion in `decks_test.go`. 3. **A dropped batch is reported as "Offline, retrying."** `save-queue.mjs` correctly drops a 4xx batch and emits `failed`; `editor-entry.js:390-395` maps every non-ok state to `offline` and marks `sessionFailed`, so the person sees `slides.editor.status.offline` ("Offline, retrying") while their edits have been discarded and the resync has rebuilt the doc without them. Add a `failed` state with its own catalog line ("Some changes could not be saved; reload to continue") — the ledger deferred this to Task 7 and Task 7 did not do it. 4. **The SVG gate can be bypassed by writing the ref straight into the document.** `registerAsset` sanitises and stores clean bytes under a new hash, but the doc is written by the client's `register_asset` op, and any member can POST an update naming the *unsanitised* hash they PUT via the presigned URL. `serveAsset` (`assets.go:475-487`) then finds the ref in `view.Assets` and, with an S3 store, 302s to the raw object — served from the bucket's origin (so not an XSS on this app; the Dir path is protected by the CSP sandbox). Not a merge blocker while no store is bound; before one is, either record verified refs server-side (a small `deck_assets(deck_id, ref)` table written by `registerAsset` and required by `serveAsset`) or sniff-and-sanitise on the Dir path and only presign refs that table holds. **Minor** 5. `strip.mjs:105` re-appends every `&lt;li&gt;` on a remote reorder, which drops focus from a focused strip item (WCAG 2.2, ledger's own deferred line). Only move nodes whose position differs, and restore `document.activeElement` afterwards. 6. Presence `client` is client-chosen (`live.go:616`): a member can overwrite a colleague's cursor by reusing their client id. Cosmetic within a team; keying the map by `(user, client)` closes it. 7. `/s/{token}/assets/{ref}` and `serveAsset` generally instantiate a wasm module and replay the log per image, and the share route is unauthenticated. The per-(deck, seq) view cache the ledger deferred would cover both; until then a share-link holder can make each image cost a replay. 8. A member in a loop can open unbounded streams; each is one goroutine for up to 5 minutes. Same as Docs; a per-user cap on `Subscribe` is a later change. 9. Undo scoping is right (`trackedOrigins = {ySyncPluginKey, LOCAL}`, remote bytes tagged `REMOTE`), the CSS `[slides-editor] [hidden]` rule is right, the presence live region speaks only on join/leave — credit, no action. ### Deferred/parked triage Fix before merge: #3 (failed state), #5 (strip focus), and the ledger's "delete cascades" gap surfaces as #2. Later: 409/ping/TTL tests, `ids.mjs` test, `raw=1`, thumb scale, `data-seq`, nudge coalescing, the stage phone-override badge (record the spec §3.2 deviation in the spec), the `(deck, seq)` cache (#7), the real-bucket PUT test and the https requirement for `crypto.subtle` (say it in README), the snapshot ABI column (snapshot bytes are Yjs v1, not ABI-bound; fine to wait), the `nohash` message. Accepted: `mirrorMeta` lag window. ### Docs consistency Ten claims checked against code and all hold: 503 without a store; snapshot cadence 200; the wire's framing, headers and `since=0` snapshot; presence whole-set with name/colour from the users row; both write paths publish and snapshot; `build-bundles.mjs` deletes stale hashes; 20 MiB and four types; three capability-keyed asset routes; undo scoped to the person; the gate's step list. One wording nit: README's "CI does not build it for you" sits beside "the gate rebuilds and diffs" — say "CI does not commit it for you". ### Tests Real HTTP throughout `slidestest`; the stream test is event-driven with no sleeps; the only `time.After` is a poll in the browser drive. Seven browser drives plus the upload drive match what the reports claim. `make ci` is the Go half of the one gate, and the gate's `require_committed` restores the tree on failure — well done. ### Verdict: Needs fixes Blocking: **#1** (pre-commit parse gate in `appendUpdate` plus the tolerant view and its test), **#2** (snapshot cascade), **#3** (failed status state). Recommended in the same round because they are small: **#5**. **#4** must land before `carlos store create` is run.</result> <usage><subagent_tokens>176682</subagent_tokens><tool_uses>56</tool_uses><duration_ms>469170</duration_ms></usage> </task-notification>
