Report is at `.superpowers/sdd/2026-09-08-slice-3-export/task-1-report.md`. **VIABLE** - Commit `b04cccb` — `spike: svg2pdf under wasm32 — viable` (12 files; spec §1 row 13 added). - Module: `slides_pdf.wasm` 3,672,361 bytes (3.50 MiB), 0 host imports, byte-reproducible, no getrandom in the graph (no vendoring/patching needed). - Tests: Rust 5/5 (`no_host_imports`; text as Type0/CIDFontType2 + `FontFile2` subset `XFNOQL+LiberationSerif` + ToUnicode, `Tj` in inflated stream; 2 SVGs → 2 pages; ABI frame errors; PNG `<image>` embeds). Go wazero spike passes: compile 746 ms, render 5 ms/page, 200 pages in 140 ms at 7.6 MiB memory. - Concerns (detailed in report): font subset embedded per page, not per document (~7 KB/page/face); per-glyph `Tj` (extraction via ToUnicode, `pdftotext` not installed to confirm); only JPEG/PNG/GIF — any other raster fails the whole render, so the SVG encoder must never emit WebP; gate `.amadan/ci.d/10-gate` not yet wired for `core/pdf` (outside my file allowance; Task 4); `make ci` currently fails in `internal/slides/render` from the other agent's in-progress edits, not mine; first `cargo fetch` needed the sandbox off (read-only `~/.cargo/registry`).</result> <usage><subagent_tokens>155626</subagent_tokens><tool_uses>71</tool_uses><duration_ms>785538</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. Working tree clean; nothing of the other agent's touched. **Commit:** `effa68d feat: embedded Liberation fonts on every surface; the layout engine` **Tests:** `make ci` green (vet, gofmt, all Go tests, migration check). Browser drive **ran and passed** — it failed on `socket()` under the sandbox as predicted, so I re-ran it with the sandbox off. New goldens: `render/testdata` (font stacks only, one line each) and `layout/testdata/*.golden.json` (nine slides). **Concerns (full list in the report):** - `slides.css` has a real bug: `[slides-slide] { gap: var(--slides-gap) }` is a `cqw` on the query container itself, so region spacing and two-column widths move with the browser window. The engine uses the fullscreen-1920 value; fixing it needs the grid moved off the section. - Driving the numbers through Chromium found two errors I'd otherwise have shipped: `1cqw` is 16.8 not 19.2 on padded templates (content box, not border box — six templates were 12.5% oversized), and flow images/shapes are flex items that shrink. Both are now pinned by a browser test. - Fonts are duplicated (4.2 MB × 2) per the brief; `@font-face` uses the real family name, where Docs deliberately uses a private one. Both are one-line changes if you want them different. - I followed slides.css over three of the brief's parentheticals (divider thickness, quote italic/no rule, line heights) and the brief over slides.css on one (a shape's label is drawn). **Report:** `/home/paulca/amadan.net/oficina/slides/.claude/worktrees/slice-1/.superpowers/sdd/2026-09-08-slice-3-export/task-2-report.md`</result> <usage><subagent_tokens>389681</subagent_tokens><tool_uses>165</tool_uses><duration_ms>2600311</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 now have sufficient evidence to write the full review. ### Spec Compliance Task 2's scope matches the brief exactly: only `internal/slides/fonts/`, `internal/slides/layout/`, `internal/slides/static/{fonts,slides.css}`, and a minimal, behavior-preserving seam extraction in `internal/slides/render/{render.go,themes.go}` are touched. No files owned by the concurrent SVG/thumbs/pdfcore/export tasks were touched. - **Fonts everywhere**: twelve Liberation TTFs embedded in both `internal/slides/fonts/files/` and `internal/slides/static/fonts/`, byte-identical (`TestServedFontsMatchTheEmbeddedOnes`), OFL licence served at both locations. `fonts.go` API matches the brief: `Role{Heading,Body,Code}`, `Face{Family,Bold,Italic}`, `Get`, `Data`, `Metrics`, plus a documented, justified deviation on `Advance`'s signature (`(width, missing []rune)` instead of a single value) to satisfy §11's degrade-loudly rule — reasonable and disclosed. - **`truetype.go`**: diffed byte-for-byte against `/home/paulca/amadan.net/oficina/docs/internal/fonts/truetype.go` — identical except the documented header and the one intentional change (`Data(f)` instead of a `Data` field, `f.File()` method vs field), exactly as claimed. - **`layout.Layout(d, index) (Paint, []Warning, error)`**, `Paint{W,H,Background,Ops}`, `Rect/Ellipse/Line/Image/Text{Runs}` — signatures verified directly against the brief, no drift. - **`regions.go` + `regions_test.go`**: the structural test genuinely regex-parses `grid-template-areas` (and scoped `grid-area` rules) out of `slides.css` and cross-checks region-name sets against the table, both directions. Not a rubber-stamp. - **1 cqw mapping**: verified in `sizes.go`/`regions_test.go` and pinned by a Chromium browser test. `scaleFor` correctly maps `padded` (16.8px) to the six templates that keep the section's 6.25% padding and `full` (19.2px) to `image-full` and every canvas slide (both drop padding in `slides.css` at lines 324 and 582-585) — checked against the CSS directly, mapping is correct per-template, not global. - **Greedy line breaking, never clip**: confirmed in `text.go`; overflow surfaces as `Warning{Kind: WarnOverflow}` rather than a `MaxLines` field literally — a reasonable, disclosed reinterpretation of the brief's wording that achieves the same "never clip, report" contract (`TestALongWordOverflowsRatherThanBeingCut`, `TestABlockTallerThanItsRegionIsReported`). - **Blocks**: table is equal-width columns with header bold (`colW := s.w/cols`, `head.face.Bold = true`), columns block clamps `count` to 2 or 3 and lays out equal-width children left to right, phone layer is never read (`TestThePhoneLayerIsNeverRead`), canvas z-order confirmed stable-sorted (`TestCanvasPaintsInZOrder`). - **Goldens**: 9 golden files for 9 fixture slides covering all 7 flow templates (including `blank`, which the real `sample.go` doesn't even use) + both canvas modes + every block type in §2.4, `-update` flag present, `TestNoOpIsNaNOrNegativelySized` guards every golden against NaN/Inf/negative sizes. - **`@font-face` hashes**: URLs carry a 16-hex SHA-256-derived content hash; spot-checked one against the actual file — matches. `TestSlidesCSSFontURLsCarryTheirContentHash` and `TestTheAppServesTheDeclaredFontFiles` (asserts `immutable`) both exist and are meaningful. - **`TestThemeContrast`**: verified it tests only hex colours, unaffected by the font change, still meaningful. Render goldens diff-checked line by line — the only changes are the font-stack strings, everything else (colors, structure) is byte-identical. - **Browser test**: compiles under `-tags browser` (`go vet` clean), uses the shared `harness` package which skips visibly without Chromium (`t.Fatal`/`t.Skip` gated by `RASTRILLO_BROWSER_OPTIONAL`) and is otherwise bounded by Go's test timeout — no retry/poll loops, one fixed 2s `chromedp.Sleep` for font load (see Minor issue below). - **`go test ./internal/slides/layout/ ./internal/slides/fonts/ ./internal/slides/render/... ./internal/slidestest/...`** all pass with `-count=1` (39.8s for slidestest, non-browser-tagged). ### Strengths - Exceptional traceability: nearly every non-obvious number in `sizes.go`/`regions.go` cites the exact `slides.css` rule it derives from, and the browser test that caught the two real bugs (cqw-on-content-box, flex-shrink) is kept as a permanent regression pin rather than being thrown away after the bugs were fixed. - The `slides.css` `gap`-on-container bug is diagnosed correctly (verified: `[slides-slide] { gap: var(--slides-gap) }` is written on the container itself, an element can't be its own query container), the engine's choice to use the fullscreen value is right for an export/projector engine, and it's disclosed rather than silently patched around. - `render.go`'s `SlideVars`/`ThemeID` extraction is clean and provably behavior-preserving (golden diffs show zero output change besides font strings). - The `Advance` missing-glyph handling is properly tested against non-BMP/CJK input and confirmed non-panicking. ### Issues **Minor** - `internal/slidestest/browser_layout_test.go` uses a fixed `chromedp.Sleep(2_000_000_000)` (2s) to wait for the stylesheet and fonts to apply, rather than polling `document.fonts.ready`. It's bounded and documented, not a hang risk, but it's the one named-risk item ("no sleeps") not fully met — a flaky-CI risk if font load ever takes longer than 2s on a loaded box. - Divergences from the brief's literal wording on divider thickness (8.4px vs. an implied 2px) and quote styling (italic, no left rule) are well-justified by reading the actual `slides.css` (verified: divider `block-size: var(--slides-rule)`, quote `blockquote { font-style: italic }` with no border-left declared anywhere) and consistent with the plan's "stylesheet is the truth" doctrine — flagging only because it's a deviation from the brief's parenthetical, not because it's wrong. No Critical or Important issues found. ### Assessment: Approved Every named-risk check (a–j) verified directly against source, not just the report's prose: the TrueType parser is copied verbatim, the regions test really parses the CSS grid, the 16.8/19.2 cqw split is applied correctly per template, goldens are guarded against NaN/negative values, `TestThemeContrast` remains valid and render goldens changed only in font strings, the browser test is bounded and skips cleanly, font URLs carry verified-correct content hashes with a licence-serving test, table/columns layout is equal-width with bold headers, and canvas z-order is stable-sorted. Focused test runs pass. The two disclosed divergences (slides.css's `gap`-on-container bug, and following slides.css over the brief's parenthetical on divider/quote) are reasoned, documented, and consistent with the plan's own "the paint list is the only input" / stylesheet-is-truth constraints — not compliance failures.</result> <usage><subagent_tokens>125978</subagent_tokens><tool_uses>70</tool_uses><duration_ms>281633</duration_ms></usage> </task-notification>

Commit: `0ca08b0 feat: PDF export through the slides_pdf module` (10 files, scoped by path). Tests: Rust 7/7 (`core/pdf`, incl. 2 new ABI edge tests); Go `pdfcore` 9/9 (fresh instance per render, `Rejected` on malformed SVG, deadline → `DeadlineExceeded`, 200 pages in 668 ms); Go `internal/slides` 5 new (sample deck headings recovered as glyph runs via ToUnicode+Tj, notes ≥ 2×slides, 201 refused/200 rendered in 553 ms, images inlined/downscaled/dropped with warnings, box-filter unit test). `make ci` green; gate's new pdf steps (fmt, clippy, build, `cmp`, `cargo test`) run green by hand; full gate not run (`npm ci` needs the registry). Module: 3,672,407 bytes (3.50 MiB), 0 host imports, reproducible (clean rebuild byte-identical to the committed copy). Concerns: (1) one font subset per page, accepted, follow-up noted; (2) the sample deck has 8 slides, not 9 — test asserts pages = `len(d.Slides)`; (3) WebP is dropped with a warning: neither stdlib nor the svg package decodes it — `golang.org/x/image/webp` is the fix, a go.mod decision; (4) `layout.Warning` carries no slide id for overflow warnings; (5) the PDF runtime is a package-level `sync.OnceValues`, not an `app` field (app.go was off-limits); (6) `pdftotext` absent — the test says so in its log; PyMuPDF used by hand to confirm extraction and rasterised pages look right.

The user can send it another message and resume it, so the same task-id may notify more than once.</note> <result>## Spec Compliance Reviewed `core/pdf` (via `b04cccb` + this diff's hardening) and `internal/slides/{export.go,pdfcore/}` against plan Global Constraints, spec §4.3, §1 row 13, and both briefs. - **§4.3 / Task 4 brief, part 1 (crate + host):** `internal/slides/pdfcore` matches the controller decision exactly — `New(ctx, opts...)` compiles once, refuses non-zero host imports, checks ABI version once; `Render(ctx, svgs, fonts)` instantiates fresh per call, runs under a 60 s deadline via `WithCloseOnContextDone`, closes unconditionally, wraps a clean module refusal as `RejectedError`/`Rejected()`, and leaves a trap or deadline as an ordinary (non-`Rejected`) error. `scripts/build-pdf-wasm.sh` unchanged from the spike; the gate rebuilds and `cmp`s. **Independently verified**: I rebuilt `slides_pdf.wasm` from source and `cmp`'d it byte-identical to the committed `internal/slides/pdfcore/testdata/slides_pdf.wasm` (3,672,407 bytes). - **§4.3 / Task 4 brief, part 2 (export pipeline):** `Export(ctx, d, ExportOptions{WithNotes, Assets})` matches the signature exactly; refuses `MaxExportSlides=200` before any layout/render work; never sets `svg.Options.AssetURL` (confirmed against `svg.go`'s `image()`, which draws nothing when neither inline nor `AssetURL` resolve — no external references possible); images capped at 20 MiB *before* `image.DecodeConfig`, then a 50-megapixel cap *before* `image.Decode` (correct decompression-bomb ordering); downscale to 2000 px long edge via a hand-written, unit-tested box filter. - **Spec §1 row 13** was already recorded by Task 1 (`b04cccb`); this diff didn't need to touch it and didn't. - **Named-risk checklist (a)–(h):** all directly verified — see Strengths/Issues below. One item (d) has a real but minor deviation from the literal brief text (font choice/size for notes), noted under Minor. ## Strengths - `core/pdf/src/abi.rs`: `host_slice` fixes real UB (`from_raw_parts` over a null pointer for a `(0,0)` pair); `in_bounds` uses `checked_add` (no overflow panic); `set_result` is documented and actually structured so no `RefCell` borrow is ever held across a `usvg`/`svg2pdf` call — confirmed by reading `render_frames`. `panic = "abort"` is set in `Cargo.toml`. `split_frames`/`render` use `.get()`-bounds slicing and `map_err`/`ok_or_else` throughout — no `unwrap`/`expect`/panicking index found in `lib.rs` or `abi.rs`. - `no_host_imports` test present, correctly gated by `SLIDES_REQUIRE_WASM`, and the gate's new steps (fmt, clippy, build, `cmp`, `cargo test`) mirror the CRDT core's four steps in the same order for the same reason. Ran it myself: `cargo fmt`/native `cargo test` (7/7 pass), and a from-scratch `./scripts/build-pdf-wasm.sh` whose output is byte-identical to the committed artifact. - `TestExportSampleDeck`'s glyph assertion is genuinely a glyph-level check, not a header check: it inflates every `FlateDecode` stream, parses each `Type0` font's `ToUnicode` CMap (`bfchar`/`bfrange`), walks `Tf`/`Tj` operators per form XObject, and recovers every slide heading and every notes paragraph's first word as real Unicode text. `pdftotext`'s absence is handled gracefully (logged, not silently no-op). - Re-ran everything myself and all pass: `internal/slides/pdfcore` (9/9), `internal/slides` export tests (5/5, including 200-slide timing at 546 ms/1.47 MB and image inline/drop behavior), Rust `core/pdf` tests (7/7 native). - `AGENTS.md` updated with the second-crate description and the wasm-staleness trap extended to `slides_pdf.wasm`. ## Issues **Critical:** None found. **Important:** 1. Every `WarnAsset` warning `export.go` emits has an empty `Block` — `layout.Warning` has no slide-id field at all, so a status page can't attribute a dropped image to a slide, only describe it in `Detail` text by asset id. This is disclosed in the task-4-report (concern #4) as intentionally deferred (widening the struct is layout's file, outside this task), but it's real today and worth confirming Task 5 will actually do it rather than letting it silently stay dropped. 2. Neither `internal/slides/pdfcore/pdfcore.go` nor the existing `internal/slides/core/core.go` sets a wazero memory limit (`WithMemoryLimitPages` or similar) on the runtime config — the only ceiling is the 60 s deadline. Not a regression introduced by this diff (matches the CRDT host's existing posture exactly), but it was on the named-risk list and remains open on both hosts. **Minor:** 1. `task-4-brief.md` specifies notes pages in "Liberation Serif 24 pt"; the shipped code uses Liberation Sans at the deck's own `--slides-t-3`/`--slides-body-m` sizes (≈67 pt title / ≈47 pt body at 1920×1080), a deliberate and commented choice to match the deck's own type scale — but it's an undisclosed deviation from the brief's literal text, not called out in the report. 2. Font subsets are embedded per page, not per document (svg2pdf's `to_chunk` has no shared-context API) — 1.7 MB for 200 text-only pages vs. an estimated <100 KB with sharing. Honestly disclosed in both reports as accepted for this slice. 3. WebP is dropped end-to-end with a warning despite being accepted on upload; disclosed as concern #3, needs a `go.mod` decision (`x/image/webp`) out of this task's scope. 4. `pdfRuntime` is a package-level `sync.OnceValues`, not owned by `app` — disclosed (concern #5) as intentional since `app.go` is outside this task's file allowance. ## Assessment **Approved.** The implementation matches the controller's decisions and spec §4.3 precisely, the named-risk checklist holds up under direct source reading and independent test/build verification (including an out-of-band reproducible-build check), and both reports' claims about test rigor (glyph extraction, reproducibility, timing) check out. The two Important items are consciously deferred, disclosed gaps rather than unaddressed defects — worth a short follow-up note (notes-page font deviation from the brief; confirming Task 5 widens `layout.Warning` with a slide id) but not blocking.</result> <usage><subagent_tokens>129731</subagent_tokens><tool_uses>42</tool_uses><duration_ms>317538</duration_ms></usage> </task-notification>

Commit: `6c757a4 feat: SVG encoder and thumbnails on every surface; grid gap fix` Tests: `make ci` green; `go test -tags browser ./...` green (browser drive ran, sandbox off — it fails on `socket()` inside the sandbox as predicted). The layout drive now pins the region gap at two viewport widths (43.68 at 1920, 17.745 at 780), which is the assertion that would have caught the original bug. `npm test` in fixtures 138/138. Bundle rebuilt reproducibly (same hash twice). Concerns: an SVG in an `<img>` fetches nothing, so thumbnails set type in whatever face the reader has locally (Liberation is not embedded — ~800KB/thumb would be); WebP cannot be inlined at all (stdlib has no decoder, so the brief's "re-encode to PNG" is impossible under the constraint) and falls back to its URL; inlining reads asset bytes per thumbnail miss; the remote's preview lost its phone reflow and is now the 16:9 picture; `docs/api.md` still lacks the `.svg` API route (task 5).

Writing the final review. ### Spec Compliance All controller decisions verified against the committed diff (base `0ca08b0` → head `6c757a4`) and confirmed by running the code (`go build ./...` clean; targeted `go test` on `svg`, `slidestest`, `layout` packages all pass; `node --test strip.test.mjs` passes): - `svg.Encode(p, Options{Title, InlineImages, AssetURL})` — matches exactly (`internal/slides/svg/svg.go:61-84`). - SVG 1.1, `viewBox="0 0 1920 1080"`, `role="img"`, `<title>` — present (`svg.go:98-103`). - One `<text>` per line, `<tspan>` per run, each run given its own `x` via `fonts.Advance` — present and tested (`TestEachRunIsPlacedAtItsOwnX`). - Links: http/https/mailto only, tested directly against `javascript:`, `data:`, `file:`, `vbscript:` (`TestOnlyWebAndMailLinksSurvive`). - Shapes with `rx`, arrow `<marker>`s, `fill="none"` written explicitly — present and tested. - Images: data URI when `InlineImages` succeeds (PNG/JPEG/GIF sniffed server-side, never client-declared), else `AssetURL`; `preserveAspectRatio`/`clipPath` for cover — present and tested. - Always well-formed XML: `esc` escapes and strips XML-1.0-illegal characters; every test parses output back with `encoding/xml`; `thumbs_test.go` parses every sample-deck slide (`TestEverySampleSlideIsWellFormedSVG`, verified passing). - Four thumbnail surfaces wired (`/d/…`, `/s/{token}/…`, `/p/{session}/…`, `/api/v1/…`), `image/svg+xml`, CSP, `nosniff`, `ETag` from `(seq, id, w)` with 304, `Cache-Control: private, max-age=0, must-revalidate` — all present, all covered by new `internal/slidestest/thumbs_test.go` (verified passing, including revoked-link 404 and stranger-403/404 cases). - Strip and presenter/remote switched to `<img>`; strip's `?seq=` cache-bust is deck-seq-based and only refetches slides `strip.mark()`ed dirty (per-slide for text/structure edits, deck-wide for theme/meta/asset changes) — correct and matches spec. - `slides.css` gap bug fixed by moving the template grid onto a `[slides-frame]` descendant of the query container; `regions.go`/`sizes.go` and every golden re-measured; browser test now pins the gap at two widths (1920→43.68, 780→17.745), with the arithmetic checked independently against `sizes.go`. - Performance test present, budget 50ms/slide, warm-up pass, skipped under `-short` (verified: matches brief verbatim). ### Strengths - The named-risk items are handled correctly and demonstrably: the 304 check in `serveThumb` happens strictly before `openDeck` (the expensive wasm replay) since the ETag is built from `d.Seq`, a plain SQL column already loaded by the capability helper (`deckForShareLink`/`presentationFor`/`deckFor`) — confirmed by reading `thumbs.go:124-136` and `models.go`'s `Deck.Seq`. - XSS surface is well covered: every text/title/fill/font-family value goes through `esc`; hrefs are allowlisted and escaped; `AssetURL` output is escaped; inlined image bytes are always server-sniffed (`sniffImage`), never client-declared MIME; the one raw-splice path (nested SVG assets) is gated behind the pre-existing `sanitiseSVG` registration-time pass and this package's own additional `<style>`/directive/proc-inst refusal — a defensible, tested design, not a new hole. - Capability resolution is fully reused (not reimplemented) across all four thumbnail routes, so revoked-link→404 and ended-session→410 behavior is inherited from the same helpers the page routes use, and each surface's `AssetURL` fallback is scoped to that surface's own base path — no cross-capability leakage. - Test coverage is unusually thorough: `internal/slidestest/thumbs_test.go` exercises all four surfaces, ETag revalidation, `?w=` bucketing, missing-slide (no stray ETag on 404), share-link revocation closing the thumbnail, and stranger/anonymous access denial — all verified passing. - The report is candid and technically accurate everywhere I checked it against the diff (WebP/GIF handling, per-request asset-read cost, nested-`<style>` refusal, remote losing phone reflow, stale `docs/api.md` line, sample-deck slide count vs. plan's "nine"). ### Issues **Critical:** none found. **Important:** - The presenter's notes window and the remote (`presentation.go`'s `slideThumbImg`) now render the current/next slide as a fixed 16:9 picture instead of `render.Phone`'s reflowed HTML. Spec §3.4 literally calls these "current and next slide thumbnails," so this is textually compliant, and it's a reasonable call — but it is a real readability regression on a phone-sized remote (fixed-width text scaled down like a photo, rather than reflowed larger). This is a product judgment call the report flags itself; I'd want explicit sign-off that "thumbnail" was meant to override the phone-reflow rule here, rather than treat this task's diff as having silently settled it. - `docs/api.md:200` still says "(An SVG thumbnail lands beside it later.)" — now false. Explicitly out of task 3's scope (task 5 brief owns `docs/api.md`), so not a task-3 defect, but flagging so it isn't lost. **Minor:** - `thumbHeaders`' CSP includes `style-src 'unsafe-inline'`, which nothing the encoder emits appears to need (no `style=` attributes or `<style>` elements are ever written — nested SVGs with `<style>` are explicitly refused). Not a vulnerability (doesn't enable script execution), but worth trimming or explaining in a comment. - No dedicated test exercises an *ended* presentation session hitting `/p/{session}/slides/{id}.svg` (410 vs 404) directly, though the underlying `presentationFor`/`presentationOver` logic is shared and presumably covered elsewhere for the page route. - `svg.inlineTypes` includes `image/gif`, but `sniffImage` (pre-existing, `assets.go`) never detects GIF and the app doesn't accept GIF uploads at all (spec §2.7 lists PNG/JPEG/WebP/SVG) — dead code, apparently there to match what `svg2pdf` can decode for task 4's PDF path rather than a thumbnail bug. Worth a one-line comment tying it to task 4 so a future reader doesn't take it as a thumbnail gap. ### Assessment **Approved.** Task 3 meets its brief and the controller decisions in full, matches spec §4.2's letter, and every named risk I checked resolves correctly (XSS surface, capability isolation, ETag-before-openDeck ordering, gap-fix consistency at two widths, per-slide cache-bust granularity, no English literals in JS, XML well-formedness). The two Important items are judgment calls already surfaced honestly in the report (remote phone-reflow tradeoff, stale docs line explicitly deferred to task 5) rather than defects introduced by this task, and the Minor items are cosmetic/forward-compatibility notes. I independently rebuilt the module and ran the SVG/thumbs/layout Go tests plus the JS strip test; all pass.</result> <usage><subagent_tokens>161282</subagent_tokens><tool_uses>64</tool_uses><duration_ms>288716</duration_ms></usage> </task-notification>

New `asset_uploads` table + migration 0008. - **2 fixed** — registration accepts only a receipt matching this deck *and* actor, unspent, <2h. A ref alone is 404. Cross-deck copy path deliberately not built (spec says why). - **5 fixed** — new `GET /s/{token}/stream`; followers stay on `/s/{token}` for page, fragment, stream and assets; sqid never rendered on a follow page; stream re-resolves the link per event. Permission mismatch settled in spec §3.4 + ruling 15. - **6 fixed** — admission rechecked in `currentUser` (sessions revoked on all devices, cookie cleared, live talks ended, `/signin?err=removed`) and in the bearer gate (401). Offboarding table in spec §6.1; share links deliberately survive. - **13 fixed** — `present.js` tracks requested vs displayed with monotonic request stamps. - **15 fixed** — `remote:<session>` with issuer logged; spec §6.2 + ruling 17. Tests: `make ci` green. New `internal/slidestest/capabilities_test.go` (7 tests) plus updated `assets_test.go`/`present_test.go` — all pass; each new test fails against the old behaviour. Browser drive `go test -tags browser ./internal/slidestest/` **ok (63.9s) only with the Bash sandbox disabled** — sandboxed, Chromium dies on `socket() failed: Operation not permitted` (controller may want `/sandbox`). Full gate deliberately not run (wave A mid-edit on `core/`, `fixtures/`, wasm). Concerns: (1) no `node --test` for `present.js` — no JS harness exists outside `fixtures/`, which was off-limits; finding 13 rests on the browser drive plus attribute assertions. (2) `fixtures/uploads.mjs` has one now-false comment line ("computing it here is what makes the presigned URL possible") — comment only, left untouched as wave A's path. (3) Registration now re-writes ≤20 MiB per picture; documented as the accepted cost. (4) I took spec rulings 14–17; wave A's are 18–19, no collision.

Full gate not run (other agent mid-edit). **Concerns:** (1) The other agent's `f1c235d` staged the spec and `docs/api.md` whole, so my spec amendments (rulings 18–20, all `codex 3/4/7/10` paragraphs) and api.md notes landed in *their* commit — nothing lost, attribution off. (2) `move_slide` still clones/reinserts (same hazard at slide level) — noted in spec §2.3, not fixed. (3) `AGENTS.md` should mention `Check` in the gate; left alone as the other agent was editing it.

Tree clean, one commit, not pushed. **Commit:** `174a410 fix: slide order is data too (codex 4 at slide level); export status agrees with the held bytes; docs` **Per item:** 1. **`move_slide`** — fixed in wave A's shape, not a second one: helpers renamed to `ordered_maps`/`orderedMaps` + `place_entry`/`placeEntry` (+ new `place_new` shared by `add_slide`/`add_block`); `move_slide`/`add_slide`/`duplicate_slide`/`remove_slide` never rebuild the array; view sorts and hides `order`, so no downstream reader changed. `changes.mjs` had to learn that a slide's own `order` key is a strip re-sync. Tests in Rust, Node and Go (over the wire). 2. **Export status** — page, fragment and API status fall back to the app's hour-long record (`exportFallback`); reasoning in the code and spec §4.3. Chose the fallback over shortening the hold: the other way takes away a promised download. `ForgetExportJobs` is the test seam; the test fails 404 without the fix (verified for both the page and the API arms). 3. **AGENTS.md** — `Handle.Check` beside `deck.Parse`, a reading-order seam, both wasm artefacts + ABI-2 traps, offboarding recheck, `asset_uploads`/migration 0008. 4. **`uploads.mjs`** — false comment corrected; the app mints the staging key, the client's hash is a claim. **Tests:** Rust 30+1+12 / 1+6; Node 149 pass; both wasm `cmp` identical; bundle reproducible (`editor.ea69e9f399e840e0.js`); `make ci` green. Only `every-block.yjs` moved bytes — no `.view.json` moved. **Gate:** full `.amadan/ci.d/10-gate` on a clean `git archive HEAD` of `174a410` → `gate: ok`, `gate exit=0`. **Browser drive:** `ok 61.6s` — fails on `socket()` inside the Bash sandbox, passes with it off (ran it that way). **Concerns:** `duplicate_slide` still inserts at array `i+1` (harmless, untidy); `ForgetExportJobs` reassigns fields without a lock (test seam only); a slide's `order` isn't `Check`-validated, same tolerance the block key has; wave B's `present.js` test and bearer upload gaps remain.
