Looking good for a first slice. Let's keep going with the plan.

The user can send it another message and resume it, so the same task-id may notify more than once.</note> <result>Confirmed correct, all good. ### Findings 1. **Write-conflict retry (409)**: ADDRESSED — `internal/slides/decks.go:283-287` maps `gorm.ErrDuplicatedKey` from the `DeckUpdate` insert to `errDeckBusy`, with a comment explaining the two-lock relationship. `TestConcurrentWritersConflictThenRetry` (decks_test.go:611) and `TestApiOpsConflictIs409` (api_test.go:565) both pass. 2. **`set_meta` syncs `decks.title`/`theme`**: ADDRESSED — `metaRowUpdates` (api.go:570-403) pre-scans the batch, last-write-wins, theme gated by `validTheme` (decks.go:548), passed into `applyOps`' single transaction (decks.go:294-298). `TestApiSetMetaUpdatesTheDeckRow` passes. 3. **Token off the GET URL**: ADDRESSED — `createAgent` now renders the page directly with `Cache-Control: no-store` (agents.go:508, 224-226) instead of redirecting; `agents` GET handler no longer reads `?new=` (agents.go:374). `TestAgentTokenShownOnceAndHashed` passes and explicitly checks a replay via `/agents?new=&lt;token&gt;` shows nothing. 4. **`deleteDeck` cascades presentations**: ADDRESSED — live sessions read and rows deleted inside the transaction (decks.go:528-543), `hub.Publish(Ended: true)` fires only after the transaction commits successfully (decks.go:556-561). `TestDeletingADeckEndsItsPresentations` passes. 5. **Copy fixes**: ADDRESSED — `slides.viewer.empty.body` reworded (en.toml:707), no mention of "editor"; `PRODUCT.md` now says 143 keys, matching `grep -cE '^[A-Za-z0-9_.-]+ *=' internal/slides/locales/en.toml` = 143. One-liners: all ADDRESSED — `createPresentation` uses `errors.Is(err, gorm.ErrDuplicatedKey)` (presentation.go:349-353), `isUniqueViolation` removed, `strings` import still used elsewhere so no unused-import breakage; `readJSON` rejects trailing bytes via a second `Decode` into `json.RawMessage`, checking `errors.Is(err, io.EOF)` so trailing whitespace/newline still passes (api.go:290-321, verified by test at api_test.go:504-505 which POSTs a trailing `\n` and expects 200); `share.html` Revoke buttons carry `aria-label` (share.html:865-866, share.go:834); `docs/api.md` documents the agent-session pairing gate (docs/api.md:118-127), consistent with `presenterNotes`' `holder &amp;&amp; presenter` gate. Named-risk checks: - (a) Pre-scan correctness: verified by code inspection — two `set_meta` ops in one batch: map assignment overwrites, last wins; `set_meta` without `title`: `has` guard leaves that column untouched; a refused batch (h.Ops validation failure) returns before the `Create`/`Updates` calls, so the transaction never runs and the row is untouched — reinforced by the pre-existing `TestSettingsRowAndDocumentChangeTogether` which proves a mid-transaction row-update failure leaves the row unchanged. No test exercises the two-set_meta-in-one-batch or omitted-title cases directly, but the logic is straightforward and covered by reading. - (b) 200-on-POST: `no-store` set before render (agents.go:224-226), confirmed by test; the re-POST-on-refresh tradeoff is explicitly documented in the handler comment and docs/api.md, not specially handled in code — acceptable per the report's own framing. - (c) `deleteDeck` publish ordering: confirmed after-commit only, code at decks.go:552-561 (loop is after the `if err != nil { return }` check following `Transaction(...)`). - (d) 409 test honesty: `TestConcurrentWritersConflictThenRetry` runs a genuine two-handle sequential race (no sleep/goroutine needed since it's deterministic ordering); `TestApiOpsConflictIs409` stages via direct SQL decrement, documented as approximating "already lost" state, both attempts in `applyAgentOps` genuinely re-read the row (decks.go / api.go:543) — confirmed by trace-through. - (e) `readJSON` trailing-whitespace: confirmed `io.EOF` correctly matches trailing whitespace/newline; test at api_test.go:504-505 explicitly asserts trailing `\n` still returns 200. ### New Breakage in Fix Diff (Critical/Important only) None found. `go build ./...`, `go vet ./...`, and `go test ./...` all pass clean on 3e2b142. ### Out-of-Scope Observations - `share.go:124` still reads a `new` token from the query string for share-link creation (a different, pre-existing feature, unrelated to the agent-token GET-URL fix) — not a regression, just noting it wasn't touched and isn't in scope. ### Verdict All findings addressed.</result> <usage><subagent_tokens>83499</subagent_tokens><tool_uses>20</tool_uses><duration_ms>129452</duration_ms></usage> </task-notification>

Commit: `3e2b142` — fix: final review — conflict 409, set_meta row sync, token off the URL, presentation cascade, copy (both trailers present, tree clean). Tests: TDD, each red first. New/updated — `TestConcurrentWritersConflictThenRetry` (package-internal, failed with "duplicated key not allowed"), `TestApiOpsConflictIs409` (reachable without sleeps by staging the race: row put one seq behind its log), `TestApiSetMetaUpdatesTheDeckRow`, `TestAgentTokenShownOnceAndHashed` (POST 200 + no-store, token in no URL; `mintAgent` helper updated), `TestDeletingADeckEndsItsPresentations` (real SSE stream must hear `"ended":true`; failed on deadline before), trailing-bytes cases in `TestApiRefusesBodiesItCannotRead`. `make ci` green: vet, gofmt, all packages ok, "models and migrations agree". Report at `.superpowers/sdd/2026-09-07-slice-1-live/final-fix-report.md`. Concerns: (1) item 2 uses the batch pre-scan rather than the resulting view — the view only exists after the commit, so deriving from it would hold SQLite's writer inside the transaction; `set_meta` is the only op touching meta, so the two agree. An agent setting `title: ""` now blanks the row title as well as the document's, which is the row mirroring the document by design. (2) `docs/api.md`'s new present paragraph reflects `presenterNotes`' `holder &amp;&amp; presenter` gate: an agent's session shows no code/QR on any page, so the JSON is the only source. (3) The token-page change breaks POST-redirect-GET on `/agents`; refresh re-POSTs and mints another agent (visible and revocable) — documented in the handler comment. (4) `share.go` still redirects its share-link token in a URL; the review scoped this fix to the agent token, so I left it. (5) Full `.amadan/ci.d/10-gate` not re-run — nothing under `core/` changed.</result> <usage><subagent_tokens>162668</subagent_tokens><tool_uses>123</tool_uses><duration_ms>839182</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 did this review myself in five passes (docs and ledger; router, auth, API and presenting; decks, share, viewer, hub and templates; catalog, tests, gate and docs; the canary and one experiment in a scratch copy under `~/.claude/tmp`, the worktree untouched). `go vet`, `gofmt`, `rastrillo migration check` and `go test ./...` are green on `d8ec71e`. ### Summary Slice 1 is a careful, well-seamed implementation: the security surfaces (allowlist oracle, hashed capabilities, missing-vs-revoked, cookie/bearer isolation, Referer redirect, CSP/Referrer-Policy on the canary) hold up under cross-cutting inspection, and the canary answers the right shapes (`/api/version` → `d8ec71e`, JSON 401 on `/api/v1`, HTML 404 on `/s/`, `/p/`, `/r/`). Two Important defects sit in the write path: the optimistic-lock retry in `applyOps` is dead code (a real conflict returns a wrapped `gorm.ErrDuplicatedKey`, not `errDeckBusy`, so the API answers 500 where `docs/api.md` promises 409, proven by a test in the scratch copy), and an agent's `set_meta` never updates the `decks` row, so the list, the API list and the settings page drift from the document. Nothing is Critical: no data is lost or exposed by either. ### Plan alignment Deviations, all recorded in the ledger and justified except where noted: - `slides.New` returns `(*http.ServeMux, *app, error)` with `Close` (ledger, Task 3). Fine. - Concern packages nested under `internal/slides/` (ruling; `migration check` needs one dir). - Sqids: plan said `sqids-go` from `ID`, min length 8; `decks.go:33-58` mints 10 random chars over Docs' alphabet. Better than the plan (unguessable, no ID leak) but **not recorded as a deviation**. Note it in the ledger. - `decks.html` has no Present/share affordances (ruling, Task 6): one entry point in the viewer. Fine. - `applyOps` signature grew a `rowUpdates` map (fix round, Task 3). Fine. - Spec §3.4 "the slide's transition" is not rendered on `/p/{session}`; `transition` is in the model only. Not mentioned anywhere; Minor. - `present.js` is 117 lines, under the plan's 120. Everything else in the file map exists where the plan put it. ### Findings #### Critical None. #### Important 1. **The write-conflict retry never fires; a real conflict is a 500, not a 409.** `internal/slides/decks.go:262-273` inserts `DeckUpdate{Seq: d.Seq+1}` *before* the `WHERE id = ? AND seq = ?` bump at `:278`. rastrillo's `db.Open` sets `TranslateError: true` (`db/db.go:97`), so under the `(deck_id, seq)` unique index the loser's insert returns `gorm.ErrDuplicatedKey`, wrapped at `:271` as `"record deck %s update %d: %w"`, and `editDeck` (`:322`) and `applyAgentOps` (`api.go:470`) see `!errors.Is(err, errDeckBusy)` and give up. Reproduced in the scratch copy: second writer got `slides: record deck … update 1: duplicated key not allowed`, `errors.Is(err, gorm.ErrDuplicatedKey) == true`, never `errDeckBusy`. Data is safe (the transaction rolls back), but two agents on one deck get a 500 with `{"error":"internal"}` and an HTML writer gets the 500 page, while `docs/api.md:65,178` promise 409. Fix: in `applyOps`, `if errors.Is(err, gorm.ErrDuplicatedKey) { return errDeckBusy }` on the insert (or do the seq bump first and insert second), and add the two-handles-one-seq test above to `decks_test.go`. 2. **An agent's `set_meta` leaves the `decks` row stale.** `api.go:396` calls `applyOps(..., nil)` with no `rowUpdates`, so `title`/`theme` in the document move but `decks.title`/`decks.theme` do not. `decks.go:456` (list), `api.go:243` (API list `title`), and `decks.go:730` (settings pre-fill) all read the row; the viewer reads `view.Meta.Title`. `models.go:64-66` says "both move together on every write" and `docs/api.md:247` documents `set_meta` as the way to set the title. Fix: after a successful batch in `applyAgentOps`, derive `rowUpdates` from the resulting view's `Meta.Title`/`Meta.Theme` (the view is already returned by `applyOps`) and fold them into the same transaction, or have `apiOps` scan the batch for `set_meta` and pass `title`/`theme` as `rowUpdates`, validating `theme` with `validTheme`. 3. **Agent tokens ride a GET URL.** `agents.go:451` redirects to `/agents?new=sl_…`, a 238-bit long-lived write credential landing in browser history, the CARLOS edge's access log, and the `Referer` of every same-origin click made from that page. The share and remote tokens are URL capabilities by spec design, so their `?new=`/`?t=` is the accepted trade; the agent token is meant for an `Authorization` header only and is worse to leak. Fix: render `agents.html` straight from the POST with a 200 (the double-submit guard in `rastrillo.js` and a `Cache-Control: no-store` cover the PRG concern), or stash the token server-side under a one-shot random nonce and redirect with the nonce. 4. **`deleteDeck` does not cascade `presentations`.** `decks.go:876-892` deletes updates, grants and share links but not `Presentation` rows. A live session on a deleted deck keeps its pairing code "taken" for 12 h (`createPresentation`, `presentation.go:340`), `liveSessionFor` still finds it, `/p/{sqid}` answers 404 from `deckOf` while `/p/{sqid}/command` still writes to the row, and the audience never hears `ended`. Fix: `tx.Where("deck_id = ?", d.ID).Delete(&amp;Presentation{})` in the same transaction, and `a.hub.Publish(sqid, Event{Ended: true})` for any live one after commit. 5. **`slides.viewer.empty.body` still says "Add one from the editor"** (`locales/en.toml:181`). Confirmed. There is no editor; an agent or the API is the way. Fix the sentence before merge since it renders on a real state. #### Minor - `createPresentation` (`presentation.go:352`) string-matches `"UNIQUE"` via `isUniqueViolation` while `createDeckRow` (`decks.go:355`) uses `gorm.ErrDuplicatedKey`; with `TranslateError` on, the driver text may not contain `UNIQUE` at all. Use `errors.Is(err, gorm.ErrDuplicatedKey)` in both. - `share.html:56-58`: the Revoke button has no accessible name naming the link, while `agents.html:52` does (`aria-label="Revoke {principal}"`). Add `RevokeAria` with the created date. - `saveDeckSettings` writes the row through `applyOps`' `WHERE id = ? AND seq = ?` (`decks.go:278`), i.e. not owner-scoped in SQL; ownership is established by `ownedDeckFor` just before. Acceptable given team decks are meant to be writable, but note it against SKILL.md §3. - `presenterNotes` shows the pairing block only for `holder &amp;&amp; presenter` (`presentation.go:735`); a session started via `POST /api/v1/decks/{sqid}/present` has `Actor = agent:N`, so a person opening `notes_url` never sees the QR/code. The JSON carries both, so it works, but say so in `docs/api.md:194-216`. - `/s/{token}` performs a write (`views + 1`, `share.go:319`) and a full wasm replay per request from an unauthenticated holder; `/p/{session}/stream` lets any sqid holder open unbounded SSE goroutines (5 min each). Bounded per request, unbounded in count; Docs made the same trade. Worth an edge rate limit note in AGENTS.md. - `readJSON` (`api.go:188`) does not reject trailing bytes after the JSON value; add `dec.Decode(&amp;struct{}{}) != io.EOF` → 422. - `PRODUCT.md:151` says "121 keys today"; `en.toml` has 142. The ledger's "off by 2" is now off by 21. - `app.go:170` comment says `/api/v1` is mounted "ahead of" the chi router; `ServeMux` picks by pattern specificity, not order (ledger already parked this). - Spec §3.4 transitions (`fade`) are not rendered on the surface; either render `data-transition` and a CSS rule or record it as slice 2. - `presentation.go:1003` `heartbeat.Reset` on an undrained timer relies on Go 1.23+ semantics; `go.mod` says 1.25, so fine, but pin the reason in a comment. **Done well:** `gateBegin`/`sameAnswer` (auth.go:120-208) is the most careful allowlist-oracle defence I have seen in the family; `visibleDecks`' parenthesised OR; hashed capabilities with constant-time compares everywhere; `presentStream` subscribing before re-reading the row; the hub dropping rather than skipping; the API mounted on the `ServeMux` outside `csrf.Protect` with `bearerActor` reading only the header (verified: `/api/v1/decks` with a cookie is 401, and no HTML route accepts an agent bearer, `presentCommand`'s bearer is the remote token); `render.Slide` filtering hrefs and always emitting `alt`; the templates carry no literal English (scanned: only the "Slides" brand, a recorded ruling), bare `rst-*` grammar with only allowed utility classes, 56 px remote targets, blackout as words; the test suite hits the real router, the SSE test is bounded by a 10 s context and there is not a `time.Sleep` anywhere. ### Deferred/parked triage Fix before merge: - Task 8 minor: `slides.viewer.empty.body` mentions an editor (Important 5 above). - Task 7 minor "409 branch untested": it is untestable because it is unreachable (Important 1). The test I wrote above is the missing one. - Task 8 minor: PRODUCT.md key count (one line). Can wait (follow-up issue each): - Copy-review of every new string by Paul (Tasks 1, 5, 6, 7): not a code defect; gate on Paul. - Task 3: `decks.go` size; `theme.invalid` integration test. Task 4: `render.go` size; `meta.aspect`; indent 2-3 untested; CSS unseen in a browser (walk the canary once signed in). - Task 5/7: hand-written `readonly` field, upstream request to rastrillo `field-text`. - Task 6: Present twice mints a fresh token (documented); two simultaneous presenters pick the newest session; `goto` out-of-range is in fact tested (`present_test.go:246`); bearer callers to `/p/*/command` must send `Origin` (documented in `api.go`). - Task 7: no API rate limit; nested `duplicate_slide` on a 409 retry (moot until Important 1 lands, then re-check `mintOpIDs` is idempotent across the retry — it is, ids are written into `ops` on attempt 0). - Task 1 minors (Sec-Fetch-Site making Origin dead in the test POST helper is already covered by `postLegacy`; `extractEnvFlag` now refuses a valueless `-env`). - Task 9: DNS CNAME for `slides.oficina.works` and the `SLIDES_ORIGIN` flip; the branch discussion and `amadan ci status` exit 0 are still owed per AGENTS.md before the squash. ### Verdict: Needs fixes Blocking: (1) map the duplicate-key insert to `errDeckBusy` so the retry and the documented 409 exist, with the conflict test; (2) sync `decks.title`/`theme` on an agent `set_meta`; (3) keep the agent token out of the GET URL; (4) cascade `presentations` on deck delete; (5) reword `slides.viewer.empty.body`. All five are small, contained changes; after them, plus the branch discussion and a green `amadan ci status`, this is ready to squash.</result> <usage><subagent_tokens>267139</subagent_tokens><tool_uses>68</tool_uses><duration_ms>475017</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>## Spec Compliance **Verdict: compliant.** Every named risk in the review brief was checked against the actual code and passes. - **Bearer gate failure modes** (`internal/slides/agents.go:597-645` in the diff, i.e. `bearerActor`): empty header → `bearerToken` returns `""` (`presentation.go:1240-1247`, reused not duplicated) → 401 `unauthorized`; wrong prefix → `EqualFold` fails → same 401; revoked and never-issued tokens both fall through `gorm.ErrRecordNotFound` to the identical 401 (no oracle); a constant-time compare runs after the indexed hash lookup. Verified with `TestApiNeverReadsCookie` (revoked path in `TestRevokedTokenIs401`). - **HTML reachable with a bearer?** No — `/api/v1` is mounted on the raw `http.ServeMux` (`app.go`), `bearerActor` is only `Use()`d inside `apiRouter()`. `TestApiNeverReadsCookie` proves the mirror: `GET /` with a bearer and no cookie still redirects to sign-in (303), and `GET /api/v1/decks` with a valid session cookie and no bearer is 401. - **CSRF ruling.** Verified independently by reading `/home/paulca/go/pkg/mod/amadan.net/rastrillo/rastrillo@v0.26.0/csrf/csrf.go:25-45`: `SameOrigin` falls through all three checks to a bare `return false` when `Sec-Fetch-Site`, `Origin`, and `Referer` are all absent, which is exactly what a non-browser client sends. The report's claim is accurate. - **Ops id-minting before validation.** `mintOpIDs` (`api.go`) mutates the local `ops` slice in place, but the response body on a rejected batch (`apiInvalid`, called from `apiOps`'s `default` branch) only ever carries `error`/`message`/`op` — the `ids` map computed in `applyAgentOps` is discarded on every non-nil error return, so a refused batch never leaks minted ids. Confirmed against `core/src/ops.rs:1092-1121`'s two-pass check/apply split, which really does write nothing on a rejected batch. - **`If-None-Match`.** `matchesETag` (`api.go`) handles a comma-separated list, `*`, and weak (`W/`) validators per RFC 9110, checked before `openDeck` runs (skips the wasm replay entirely on a 304). - **1 MiB limit.** `readJSON` wraps `r.Body` in `http.MaxBytesReader(w, r.Body, maxAPIBody)` and unwraps `*http.MaxBytesError` via `errors.As` to answer 413; exercised by `TestApiRefusesBodiesItCannotRead`. - **`present` reuse.** `apiPresent` calls the same `livePresentations`/`createPresentation` (`presentation.go`) that `startPresenting` uses, scoped by `actor` the same way, so repeated calls re-pair rather than duplicate — matches `TestApiPresentStartsATalk`'s "same session twice" assertion. - **Actor rendering escaping.** `lastChangeBy`/`rowSub` write the badge string (`🤖 name~email`) into a plain Go `string` field consumed by `html/template` (`render.go` imports `html/template`), so it is contextually auto-escaped; no `template.HTML` cast anywhere in the diff. - Global constraints — `Agent` model shape, token format (`sl_`+40 `[A-Za-z0-9]`, `crypto/rand` with proper modulo-bias rejection, SHA-256 hex, constant-time compare), principal `&lt;name&gt;~&lt;email&gt;`, `agent:&lt;id&gt;` actor on every write, endpoints/JSON shapes, error identifiers, "Last change by" resolution, `docs/api.md` coverage, catalog-keyed copy, scriptless forms, rastrillo §3-4 scoping — all checked directly against `models.go`, `agents.go`, `api.go`, `decks.go`, `en.toml`, `agents.html`, and `docs/api.md`, and all match. - Spot-checked every `docs/api.md` curl example's route and JSON shape against the handlers and against `core/src/ops.rs`'s actual `Op` field names (`markdown`, `new_id`/`new_block_ids`, etc., not the spec's looser prose) — all accurate. ## Strengths - The CSRF-mount decision is independently correct, not just asserted — I read `csrf.go` myself and it holds. - The refused-batch/id-minting interaction is subtle and handled right: ids are written into the batch before the core's two-pass check so later ops in the same batch can reference them, but never surfaced to the caller unless the whole batch actually committed. - `applyAgentOps`'s single retry re-reads the deck row and reuses the ids already baked into `ops` rather than re-minting, so a retried batch can't hand back different ids for the same logical request. - Test coverage is broad and adversarial in the right places: cookie-vs-bearer isolation tested both directions, cross-operator visibility (`TestApiListsWhatTheOperatorCanSee`, `TestAgentsAreTheirOperatorsAlone`), duplicate_slide's multi-id minting, ETag staleness, and all three body-refusal paths (415/413/422). - `actorLabels`/`lastChangeBy` are two queries regardless of row count, not N+1, and degrade gracefully (empty label) rather than leaking a raw `person:7` on a deleted actor. - `docs/api.md` is accurate against the actual handlers, not the spec's paraphrase — it reflects the real field names (`markdown`, not `text`), which is what an implementer actually needs. ## Issues #### Critical None found. #### Important - **Copy not run through the mandatory `copy-review` gate.** 22 new catalog keys and all of `docs/api.md` shipped without the review the skill requires before user-facing language is written into a file. The implementer flagged this themselves (report §Concerns 1). The prose reads well on inspection, but it hasn't been through the required gate, so it should not be treated as final. Not a defect in the code under review, but it's a real gap that should close before this ships. #### Minor - `mintOpIDs`'s per-attempt `blocks` map is recomputed from a freshly reopened view on the 409 retry, but `new_block_ids` (once already minted on attempt 0) is not regenerated — so a `duplicate_slide` chain inside one batch that depends on a later op's block count could theoretically use a stale count if a concurrent writer changed the *source* slide's block count in the retry window. Extremely narrow (needs a genuine 409 race plus a same-batch nested `duplicate_slide`), and the report already discloses the 409 path as untested end-to-end (`api.go`'s `applyAgentOps`). Worth a follow-up test once the harness has a seam for concurrent writers, not worth blocking on. - Self-disclosed, reasonable-as-is perf notes (`api.go`'s `apiListDecks` opening every deck for a slide count; `apiGetDeck` reading the view twice) mirror pre-existing costs `decks.go`'s own list screen already pays — no new problem introduced, just inherited. - `app.go`'s comment that `/api/v1` is mounted "ahead of" the chi router implies registration order matters for `http.ServeMux` routing; it doesn't — `ServeMux` picks the most specific pattern regardless of order. Harmless (the more-specific pattern always wins here), but the comment overstates the mechanism. ## Assessment **Task quality:** Approved **Reasoning:** Every named risk in the review brief was verified against the actual code (not just the report's claims) and holds up: the CSRF-mount rationale is correct per an independent read of `csrf.go`, the bearer gate fails closed and uniformly across revoked/malformed/empty/wrong-prefix cases, minted ids never leak on a refused batch, `If-None-Match` and the 1 MiB body limit are implemented correctly, `present` correctly reuses the existing presentation machinery, and actor strings are safely auto-escaped. Tests are substantive and check the properties that matter (isolation, atomicity of refused batches, visibility scoping) rather than just happy paths. `docs/api.md` was spot-checked endpoint-by-endpoint against the handlers and the core's real op vocabulary and is accurate. The only outstanding item is procedural — the mandatory copy-review gate wasn't run — which the implementer already surfaced and which doesn't affect the correctness of the code itself.</result> <usage><subagent_tokens>147569</subagent_tokens><tool_uses>41</tool_uses><duration_ms>348319</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>**Status:** complete, `make ci` green (vet, gofmt, tests, migration check). **Commit:** `d8ec71e` — `feat: drive API with agent principals` (branch `worktree-slice-1`, not pushed). **Tests:** 14 new in `internal/slidestest/{agents,api}_test.go` — all 7 brief-named ones plus 7 more; all failed before implementation, all pass now. **Key findings / concerns:** - CSRF ruling confirmed: `csrf.SameOrigin` explicitly refuses a request with no `Sec-Fetch-Site`/`Origin`/`Referer`, so `/api/v1/` is mounted on the ServeMux ahead of the chi router, outside `csrf.Protect`, gated by the bearer alone. Explained in `api.go`, `app.go` and `docs/api.md`. - The `op` index in a 422 is real, not inferred: the Rust core already prefixes rejections with `op {i}:`, and the handler parses it back. - Error shape follows the task constraint (`{"error":"invalid","op":N,"message":…}`), not the brief's literal `{"error":"&lt;core message&gt;"}` — `error` is a fixed identifier on every status. - `actorFor` kept its `(u User)` signature; the API composes `agent:&lt;id&gt;` from the resolved principal instead of a request-scoped switch inside a function every screen calls. - Copy was **not** put through the `copy-review` gate (22 new catalog keys + `docs/api.md`) — it needs an interactive session. - The 409 conflict branch is untested (no concurrency seam in the harness); `register_asset` has no upload endpoint yet; no in-process rate limit on the API. **Report:** `/home/paulca/amadan.net/oficina/slides/.claude/worktrees/slice-1/.superpowers/sdd/2026-09-07-slice-1-live/task-7-report.md`</result> <usage><subagent_tokens>225098</subagent_tokens><tool_uses>103</tool_uses><duration_ms>1124652</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>Good — all of these are the concurrent agent's in-progress work (matches the brief's "ignore" list), not touched by my review. My build only wrote under `core/target/`, as instructed. Now compiling the final review. ### Spec Compliance (Missing/Extra/Misunderstood; ⚠️ unverifiable) - No missing deliverables: `AGENTS.md` and `README.md` rewritten, `PRODUCT.md` created with the `&lt;!-- impeccable:product-schema 1 --&gt;` header and ten sections, `.amadan/ci.d/10-gate` created (the four scaffold steps deleted), `.amadan/ci` now execs it, `.amadan/README.md` added with the runner-allowlist note. `CLAUDE.md` correctly left untouched. - Gate step order deviates from the brief's literal listing (`cargo test`, `cargo clippy`, `build-wasm.sh`, `cmp`) — the implementation runs fmt → clippy → wasm build → cmp → test → `make ci`. This is justified and verified true: `core/tests/no_host_imports.rs` reads the wasm artifact off disk and only fails hard under `SLIDES_REQUIRE_WASM=1`, so testing before building would race the artifact's presence. Every step the brief named is present; only the ordering changed, for a documented reason. Not a compliance defect. - Two out-of-scope files were touched (`core/src/layout.rs`, `core/src/ops.rs`, `core/tests/ops.rs` reformatted; `internal/slides/core/testdata/slides_core.wasm` rebuilt) to make the new gate pass. Verified both were pre-existing faults (rustfmt drift, stale wasm) rather than newly introduced ones — the rustfmt diff is whitespace-only (confirmed by reading every hunk) and `cargo fmt --check` now passes clean; the rebuilt wasm is now byte-identical to a fresh `scripts/build-wasm.sh` build (confirmed via `cmp`). Reasonable scope creep, honestly reported. - ⚠️ `docs/api.md`, linked from all three documents, does not exist yet (task 7, concurrent) — correctly flagged by the implementer as a forward reference that could break if task 7 lands under a different filename. Not verifiable from this task alone. ### Strengths - Every named-risk check passed: rustfmt hunks are pure reformatting, the wasm rebuild is reproducible byte-for-byte off the worktree (confirms the `--remap-path-prefix` claim in `.amadan/README.md`), `.amadan/ci` execs the gate and both files are executable. - Docs are unusually well-grounded: seams (`actorFor`, `visibleDecks`, `deckFor`/`ownedDeckFor`, `openDeck`, `applyOps`/`editDeck`, `render.Slide`, `present.Hub`), env vars, routes, `clippy.toml`, `rust-toolchain.toml`, and multiple locale-catalog string quotes all matched the code exactly on spot-check. - Spec citations checked against section numbers (§0.1, §0.2, §1 rulings 2/3/5/7/8/9/11, §6.2, §6.3, §7.1, §7.2, §8) are all accurate to the actual spec text. - `[inferred — confirm]` markers used correctly in `PRODUCT.md` for the two claims that are readings rather than citations (team size, the "slide is not themed chrome" reading). - The implementer independently caught and flagged a real bug outside its touch list (`slides.viewer.empty.body` mentions "the editor," which doesn't exist in slice 1) rather than silently fixing or ignoring it. ### Issues #### Critical None. #### Important None. #### Minor - `PRODUCT.md` states `internal/slides/locales/en.toml` has "121 keys today" (Capabilities and Constraints section). Actual count is 119 (`grep -cE '^[A-Za-z0-9_.-]+ *=' internal/slides/locales/en.toml`). Small, easily-fixed factual drift — the catalog will keep moving under concurrent work, so this may already be stale by design, but as read it's off by 2. ### Assessment **Task quality:** Approved **Reasoning:** All deliverables in the brief are present and correct in substance. The three named highest-risk items (rustfmt-only diff, wasm byte-identity, gate wiring) all check out under direct verification, not just the implementer's say-so. A broad spot-check of factual claims across AGENTS.md/README.md/PRODUCT.md against the actual code (routes, env vars, seam functions, toolchain pin, clippy config, catalog strings) turned up only one minor numeric inaccuracy (locale key count off by 2), which doesn't affect any behavioral or architectural claim. The two out-of-scope file changes (rustfmt, wasm rebuild) were necessary, verified pre-existing, and honestly disclosed rather than buried. No fixes are required before merge; the locale-count nit can be picked up whenever the catalog is next touched.</result> <usage><subagent_tokens>84315</subagent_tokens><tool_uses>38</tool_uses><duration_ms>134435</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>**Status:** done. **Commit:** `3c96685` — `docs: AGENTS, README, PRODUCT and the one CI gate` (14 files; report file left uncommitted, as is the other agents' in-flight work). **Gate:** green, exit 0. Run against a clean `git archive HEAD` export, because two other agents have uncommitted work here (`internal/slidestest/api_test.go` was gofmt-unclean mid-write). Tail: `go vet` / `go test` all ok, `rastrillo migration check: models and migrations agree`, `gate: ok`. **Concerns:** - The new gate went red first run on two pre-existing faults, both fixed in this commit and both outside the task's touch list: `core/src/{layout,ops}.rs` + `core/tests/ops.rs` had never seen rustfmt, and the committed `slides_core.wasm` was already stale before that reformat (verified by stashing and rebuilding). - `docs/api.md` does not exist yet (task 7). Three documents link to it; a different filename breaks all three. - `slides.viewer.empty.body` in `locales/en.toml` tells the reader to "add one from the editor" — there is no editor in slice 1. Left alone (outside touch list); the catalog's owner should reword it. - The runner `-repo oficina/slides` allowlist edit is recorded from the brief, not verified — the unit file is unreadable from here. - Gate order differs from the brief: wasm build runs before `cargo test`, because `no_host_imports.rs` reads the artifact off disk and otherwise skips. **Report:** `/home/paulca/amadan.net/oficina/slides/.claude/worktrees/slice-1/.superpowers/sdd/2026-09-07-slice-1-live/task-8-report.md`</result> <usage><subagent_tokens>151632</subagent_tokens><tool_uses>61</tool_uses><duration_ms>556765</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>This confirms the visible-text-plus-`&lt;progress&gt;` pattern from spec §3.4 (counter text carries the semantics via a screen-reader-visible span, `&lt;progress&gt;` is `aria-hidden` decoration). All checks are complete. ### Spec Compliance **Verdict: Compliant.** All routes, the model shape, the hub semantics, the token/code/sqid capability split, the 12-hour/ended 410 handling, the scriptless floor, and audience follow all match spec §3.4/§5/§8 and the controller decisions. - `Presentation` model matches the brief field-for-field: `internal/slides/models.go:197-217`. - `present.Hub` matches interface exactly (`New`, `Subscribe(key) (&lt;-chan Event, cancel)`, `Publish`, `Event{Slide,Blackout,Ended}`, buffer 8, slow-subscriber dropped): `internal/slides/present/hub.go`. - `POST /d/{sqid}/present` via `deckFor`→`visibleDecks` (not owner-only), reuses a live session by same actor, mints a fresh token, 303s to `/p/{session}/notes?t=&lt;token&gt;`: `internal/slides/presentation.go:270-320` (matches the controller decision's `?t=`, overriding the brief's stray `?remote=`). - Routes outside the session group all present and capability-addressed: `internal/slides/app.go:73-87`. - SSE: `event: slide`, one event on connect, 15s ping, 30s write deadline, 5min TTL, `r.Context().Done()` handled: `internal/slides/presentation.go:987-1074` — exactly the constants named in the brief (`streamWriteDeadline`, `streamHeartbeat`, `streamTTL`). - `POST /p/{session}/command`: `op` next/prev/goto/blackout/end, `t` form or Bearer, constant-time compare (`subtle.ConstantTimeCompare`, `presentation.go:121`), `UPDATE ... WHERE id=? AND ended_at IS NULL` inside a transaction (`presentation.go:1170-1180`), publishes, 303 to same-origin Referer else 204 (`presentation.go:1200-1210`, using `a.sameOrigin`). - `GET /r/{code}` pair, dead code 404; `GET /p/{session}/remote?t=` four big forms (56px buttons). - Ended/&gt;12h → 410 via `ErrorPage`-equivalent `a.gone`, applied consistently through `livePresentations` (scoping query) and `presentationOver` (single-row check) — both use the same `presentTTL` constant. - Audience follow lives in `sharedDeck` (`share.go:350-368`) with `?follow=1`, scriptless `&lt;meta refresh 5&gt;`, script optional; correctly falls back to a plain redirect when the session isn't live (including mid-view — tested). - `present.js` is 117 lines (verified by `wc -l`), page complete without it, `data-remote-token` only rendered for the token holder (`present.html:65`, `present_notes.html`, `remote.html`). - QR via `github.com/skip2/go-qrcode`, inline SVG, `role="img"`, `aria-label` naming the code, black-on-white fixed: `presentation.go:qrSVG`. - Every write records an actor; every visible string is a catalog key (`en.toml` diff has matching keys for every `rastrillo.T`/`Tf` call used). ### Strengths - The hub's departure from Docs' advisory-seq pattern (drop-and-close instead of skip) is well-reasoned and directly tested (`TestSlowSubscriberIsDropped`), and the SSE handler's `case e, ok := &lt;-ch: if !ok { return }` correctly turns that into a clean reconnect. - `commandChanges` centralizes the write-shape as a `map[string]any` allowlist (rastrillo SKILL.md §4 discipline), never binding the form directly onto the model. - Three-tier capability model (sqid view / token drive / code name) is consistently enforced everywhere a session is resolved — `presentationFor`, `remote`, `remotePair`, `presenterNotes` all agree on who may see what. - `presentCommand`'s Referer redirect is checked against the app's resolved origin (`a.sameOrigin`), so it cannot become an open redirect — verified by reading `sameOrigin`'s implementation. - No token appears in any log line (`a.fail` logs only `what`/`err`/`ref`; the one `logger.Info` call logs session/op/slide/actor, not `t`), and rastrillo's own framework logging (`serve.go`) doesn't log full request URLs either. - Test coverage is unusually thorough and exercises the exact edge cases named in this review's brief: wrong/absent token → 404 (`TestWrongRemoteTokenIs404`), command on an ended session → 410 (`TestEndedSessionIs410`), follow ending mid-session → redirect back to deck (`TestFollowOfferedOnlyWhileLive`), scriptless forms (`TestScriptlessRemoteButtonsAreForms`), and `next` past the last slide clamping rather than erroring. - `go build ./internal/slides/...` compiles clean. ### Issues #### Critical None found. #### Important None found. #### Minor - **`decks.html` left untouched** despite being listed in the brief's file list. The report gives a reasoned justification (avoiding a second "Present" entry point per SKILL.md §7's anti-stacking rule), and `viewer.html` does carry the Present form — but this is a deviation from the brief that a controller should explicitly bless rather than have judged for them by the implementer alone. - **Two simultaneous live presenters on one deck**: `liveSessionFor` (used by both the audience-follow offer and by nothing else) picks only the most-recently-started session via `Order("started_at DESC")`. An audience member could be silently switched to a different presenter's session if a second person starts presenting the same deck while the first is still live. Documented in a comment, not tested, and a plausible-but-unverified edge case (spec doesn't rule on this scenario either). - **`goto` out-of-range** is handled correctly (`commandChanges` returns `errBadCommand` → 422) but has no dedicated test — only in-range `goto` and past-the-end `next` are exercised in `TestRemoteCommandAdvancesSlideAndPublishes`. Behavior is correct on inspection; only test coverage is thin here. - Bearer-caller-must-send-Origin friction (report's own flagged concern #2) is real and confirmed by reading `csrf.Protect`/`SameOrigin` — a native remote with no browser-style headers would be refused with 403 today. This is a known, accepted trade-off per the report, not a defect, but worth the controller's awareness for the "native remote" future spec mentions. ### Assessment **Task quality:** Approved **Reasoning:** Every route, model field, capability rule, and scriptless requirement in the brief and spec §3.4/§8 is implemented and matches; the three named-risk areas I traced by hand (SSE cleanup/hibernation timing, hub non-blocking Publish, token non-leakage, Referer open-redirect, 12-hour consistency, QR escaping, present.js line count and token-gating) all check out on direct inspection of the diff and, for the line count and compile-cleanliness, direct verification against the working tree. Test coverage for the request edge cases named in this review (wrong token, ended session, follow-mid-session) is present and exercises the real code paths (real SSE stream, real hub, real transaction). The only findings are minor: one undocumented-to-the-controller file-list deviation (justified but should be surfaced), a documented-but-untested multi-presenter edge case, and thin test coverage for one already-correct branch (goto out of range).</result> <usage><subagent_tokens>135894</subagent_tokens><tool_uses>49</tool_uses><duration_ms>253080</duration_ms></usage> </task-notification>

Tests: 2 hub tests + 6 named integration tests all pass (SSE asserted against a real `httptest` server under a context deadline; `-race` clean); full suite green. Concerns: - Pressing Present twice reuses the session but mints a fresh remote token, retiring a paired phone (only the hash is stored; the pairing copy says so). - A bearer caller must still send `Origin` — `csrf.Protect` is app-wide by design. - `?slide=N` on the surface is local browsing; prev/next are command forms only when the request carries the remote token (a sqid-only watcher must not drive the room). - `decks.html` left untouched (brief listed it): the row already links to the deck, where Present lives. - Copy not run through the copy-review skill — no interactive user in this session; every string is a key in `en.toml`.
