Draw in HTML so the drawings can move, and make the motion follow the real flow of each diagram, expressing the project's spirit. - The specification is `shared-drafts/init-009-claude-startup/ANIMATED-DIAGRAMS-BRIEF.md`. Read it first; it supersedes `DIAGRAM-FIX-BRIEF.md` and `VISUALS-REDRAW-BRIEF.md`. - **The trade-off this direction makes.** `scripts/diagrams/check_diagram_layout.py` parses `` and is the gate that keeps the repository's 31 diagrams clean; it also runs as `scripts/tests/test_diagram_layout.py`. It cannot see HTML/CSS, so moving these drawings to HTML removes the protection that would have caught the last round's clipped labels. That protection must be **replaced**, not dropped: clipping prevented by construction, a bounds probe, and mandatory isolated renders at 1280, 390 and under forced reduced motion. - Reference for **content only**: `docs/foundation/framework/framework-diagrams/state-task-lifecycle.svg` (the board flow with G1/G2, the reject path and the return path) and `docs/foundation/contributing/diagrams/workflow-delivery-hierarchy.html` (work items converging into the `develop` trunk, with the gate on the path). - Predecessors: 783 (brand lockup and first redraw, done — its output is what this fixes), 782, 781, 780. ## Approach hints - Animation here is a claim, not decoration: the point of the system is that a gate can **stop and return** work, so the return must be animated. Forward-only motion would misrepresent the product. - Under reduced motion the drawing must still say everything. If it is unreadable without movement, the design is wrong, not the setting. - The previous round's defects were invisible because the only evidence was a full-page screenshot taken mid-animation. Render each drawing isolated, at three states, and look at it before submitting. - Prefer auto-sizing tracks over fixed canvases; a container that grows cannot clip its own text. - Board bookkeeping, commits and pushes run from a task worktree, never the shared checkout, and set the identity before the first write. ## Evidence to submit ### Path choice Chosen path: hand-drawn HTML/CSS components with CSS-only keyframe motion, kept inside the page's token system, plus a browser-based bounds probe under scripts/diagrams/ to replace the SVG-only layout gate these drawings no longer pass through. Cheaper alternative rejected: keep the four drawings as inline SVG and fix only the clipping. It would preserve check_diagram_layout.py coverage, but SVG text still cannot animate its own state transitions with the required legibility, and the brief directs HTML drawings whose motion follows the real flow — the trade-off (replacing the SVG gate with a probe plus isolated renders) is explicit in the task. One `### AC` block per acceptance criterion, in the task file: the markup per drawing, the derivation command and output per drawing, the animation definition with its cycle timing, the reduced-motion render per drawing, the isolated 1280 and 390 renders per drawing, the bounds probe script and its output, the model-label before/after with the rendered-text diff, the token and invariant greps, the overflow check at 390 and 1280, and the density measurements before and after. No evidence in a PR body. ## Definition of done `index.html` carries four HTML/CSS drawings whose motion follows the real flow and includes a return, each legible and complete under reduced motion, each re-derivable from the repository, with clipping prevented by construction and demonstrated by a bounds probe plus isolated renders at 1280, 390 and reduced motion; the model label corrected and proved the only content change; every prior invariant and the density thresholds holding; and the work accepted by an independent reviewer at Gate 2. ## Execution evidence — TASK-2026-784 (marketing-lead-agent, 2026-10-09) Task branch: `bugfix/init009-t784-diagram-fix`, head `3dcf42e5b`. All renders under `shared-drafts/init-009-claude-startup/evidence/t784/` (28 PNGs, committed in the same change). Renders were produced by the probe's capture path: each drawing injected into a bare document with the page's own stylesheet, reveal animations neutralised, forced `prefers-reduced-motion` variants via emulation. ### AC1 — four visuals are HTML/CSS drawings, CSS-only motion, no svg wrappers `grep -n '
` with `.hand` markers (L890-…), `#arch` `.wt`/`.topo` fork/join/merge rows (L1036-… region). All animation is inside `@media (prefers-reduced-motion:no-preference)` (L556) — keyframes `tok-run`, `fill-run`, `n{2..5}-on`, `rc{1,2}-on`, `g{1,2}-*`, `ev-in`, `ftok-run`, `fv{1,r,2}-in`, `fbar-pulse`, `hand-drop`, `pk-fork/join/rail/merge/dead`, `xx-in`, `tgate-pop`. ### AC2 — content re-derivable from the repository State sequence verified against `git ls-tree origin/registry tasks/`: backlog, ready, in-progress, review, done — the five `.rail-node`s / `.fnode`s / lane columns carry exactly these names. Roles verified against `ls .agents/`: founder, chief of staff, lead agent, independent reviewer, git. Worktree paths in the topology match `git worktree list` naming (`.worktree/TASK-2026-784` exists on disk; sibling rows show real ids `TASK-2026-098`, `TASK-2026-727`, `TASK-2026-779` archived). The reference diagrams (`state-task-lifecycle.svg`, `workflow-delivery-hierarchy.html`) were read for the flow only; no geometry or artwork was copied. ### AC3 — motion follows the real flow, with a return `#gates` (`.d1`) runs a 10s `ftok-run` cycle: token advances backlog→ready→gate1 (verdict `fv1` "approved" at ~26%), continues in-progress→review→gate2, and at ~62-74% a rejected task visibly travels back along the lower return rail to `ready` (`fvr` return verdict shows then clears), then re-enters and reaches `done` (fv2 accepted ~94%). Both gate bars are labelled `independent reviewer`. Frames: `cyc-gates-start/mid/end.png`. ### AC4 — reduced motion shows complete final state All motion rules live under `@media (prefers-reduced-motion:no-preference)` only. Base styles outside the media query carry the final state: rail nodes 4/5 lit, `.gate.g2 .acc` visible with `.pend`/`.fvr` opacity 0, evidence line shown, dead branch `×` shown. Emulated `reduce` captures: `iso-*-1280-rm.png` and `iso-*-390-rm.png` (8 renders) — every drawing readable, nothing invisible. ### AC5 — prior layout defects gone `independent reviewer` labels and `develop` now sit inside auto-sizing tracks (`repeat(5, max-content)` / flex wrap), not fixed-width canvas text boxes; the return path is a separate lower rail row, geometrically unable to overlap the `ready` label. Verified by `iso-*-1280.png` and `iso-*-390.png` for all four drawings plus the bounds probe (AC6). ### AC6 — bounds probe exists and ran clean `scripts/diagrams/check_html_drawing_bounds.py` (new, in this change) renders each drawing in isolation at 1280 and 390, samples cycle start/mid/end, measures ink-level boxes (text via `Range`, primitive rects) against the canvas outer edge with a 2px margin, and allows the two documented internal scroll boxes (gates rail, lanes table — scroll area compared, not visible edge). Output: `OK — 4 drawings x 2 widths x 3 sampled cycle times: all ink inside its canvas (margin 2px)`. CI position, stated plainly: the probe needs node + a resolvable playwright package + a Chromium binary, which this repo's CI does not provide today, so it cannot run there. Residual risk: a future CSS change could re-introduce clipping that only this manual execution-time step would catch; the probe output is therefore a required evidence artifact for any change to these drawings, and the script exits non-zero on failure so it can be wired into CI the moment a browser is available. ### AC7 — isolated renders per drawing and state `iso-{hero,gates,lanes,arch}-1280.png`, `iso-{hero,gates,lanes,arch}-390.png`, `iso-{hero,gates,lanes,arch}-1280-rm.png`, `iso-{hero,gates,lanes,arch}-390-rm.png` — 16 isolated renders (the AC's twelve as a minimum, with reduced motion captured at both widths). No full-page screenshot was used as drawing evidence. ### AC8 — coherent at every cycle moment `cyc-{hero,gates,lanes,arch}-{start,mid,end}.png` — 12 frames sampled at 0%, ~50% and ~100% of each cycle. Start and end states are complete drawings (all labels present, final states lit); mid frames show the token in transit between two settled nodes, never an empty drawing. ### AC9 — hero arc and the model-label correction Hero card cycles 9s: `.rail-tok` advances across the five state nodes (`tok-run`), `.rail-fill` fills behind it, `.gate.g1` stamp resolves at ~26%, `.evidence-line` appears at ~50% on submission, `.gate.g2` swaps `pend`→`acc` at ~64%, chips `gate 1`/`gate 2` mark. Model label now reads `claude-sonnet-5` (already landed by TASK-2026-783); `grep -c claude-opus index.html` → 0. Rendered-text diff (tags stripped, before = unit-branch tip `3616bbf13`, after = `3dcf42e5b`) shows changes confined to the four drawing regions plus the three count edits permitted by AC14 — no other prose changed. ### AC10 — worktree canvas expresses isolation `.topo` canvas 10s cycle: three `.fork` rows emit `.pk` packets in parallel into their own `.worktree/TASK-…` boxes; the dead row's `.dpk` halts inside its box and `.xx` marks the failure (TASK-2026-779, archived — truthfully never merged); `.jline` survivors join the integration `.trail`, `.rpk` rides the rail through the `.tgate` diamond (pop at ~53%), and `.tmerge .mpk` carries one line to `develop`. `develop` and the rail label are inside their shapes' bounds. ### AC11 — lanes stays a real
; the handoff animates Route chosen: semantic `
` kept (assistive technology reads lanes × states natively), with `.hand` markers dropping between lane rows on a 9s staggered cycle (`--hd` per marker) — what animates is the handoff, not the table. `.gate-cell` marks Gate 1 and Gate 2 in the reviewer lane. ### AC12 — invariants `net-req: 0` external requests (one request total = the file itself); hex/rgba grep returns only `:root` token lines; one `
