Findings from a 6-agent autonomous audit (engineering, content/strategy,
cross-repo, package code review, sketch UX/a11y, codex second-opinion).
Verified each load-bearing claim before acting (ghcr.io 401, /sdk/ts/ 404,
brew tap 404, 11 H1s on /architecture/, iframe -233px desktop clip, sketch
same-row edge bug, Sharp libvips LGPL transitive).

Site copy honesty:
- Architecture H1: "Bank-Grade Platform Architecture" -> "Reference architecture
  for bank-grade internal-tooling fleets" + v0.1.0-vs-target callout note.
  Demoted 10x "# Part X" -> "## Part X" (was 11 H1s, now 1).
- Removed duplicate six-commitments recap from §4 (links to manifesto).
- Aligned starter-api stack to shipped state (Go 1.25 + chi + pgx, not
  Go 1.23 + Fiber + GORM). Marked Temporal as v1.0 target.
- Fixed OTel auto-instrumentation list (chi+pgx, not Fiber+GORM).
- Launch H1: "bank-grade foundation" -> "first SDK release". Reframed
  "everything... on a public registry you can install from right now" to
  honest "SDKs on registries; substrate from source".
- Launch table CLI: pinned-version @v0.1.1 -> @latest (avoids drift claim).
- Try-it: kept "Stand it up in an afternoon" but rewrote step 2 to use
  git-clone + values-dev.yaml (the path that works at v0.1.0); helm-OCI
  flow moved into a v1.0-target caution block. Dropped non-existent
  Homebrew tap line. Dropped Argo-CD reconcile step (it isn't shipped).
  Added kind-cluster prerequisites.
- /sdk/ index: added per-package status column (all v0.1.0 today).
- /tools/: trimmed 5 "coming soon" cards down to 2 (OTel Config + CloudEvents
  Validator) per strategist call. Softened "Excalidraw (looks amateur)"
  punch-down. Sketch promoted to its own H2 from the tools/diagrams pair.
- /examples/access-requests/: disclosed dev-cookie-shim limitation.
- Stale "Spectral" comment in astro.config -> IBM Plex Sans.
- Dropped IBM Plex Mono fallback from theme.css (JetBrains Mono is canonical).

Engineering:
- IFrameTool.astro: fixed full-bleed via JS measurement instead of
  100vw + calc(50% - 50vw) trick (which misaligns with Starlight's
  splash-template left-anchored content column, off-screen left -233px).
  Also: forwards parent location.hash into iframe src so /tools/sketch/
  share links route the encoded DSL into the embedded tool.
- Removed iframe sandbox= attr: `allow-scripts + allow-same-origin`
  together negates sandbox and Chromium warns. Same-origin anyway.
- check.yml: added permissions: contents:read minimal token scope.
- index.md: title "Plinth" (-> rendered as "Plinth | Plinth") replaced
  with the tagline. Added theme-color meta site-wide.

Sketch tool (public/tools/sketch-app.html):
- Toolbar wraps on mobile (was clipping Copy share link off-screen).
- "Empty" example now actually empty (was rendering a non-empty SVG with
  just the cite floating; placeholder text wasn't shown).
- Share-link encoding chunked to 8KB, with a 64KB DSL cap.
- Bad hash now flashes "share link malformed" instead of silently falling
  through to default.
- Status: aria-live=polite, distinct ✕ vs ● glyph for err/ok (not just
  color). Updates via replaceChildren (no innerHTML) so SR doesn't
  over-announce.
- Added <h1 visually-hidden>, wrapped editor in <main>, <label for>
  on the example select, autofocus on textarea (primary surface).
- Fixed render: shows placeholder when DSL parses to 0 nodes (was
  rendering an empty cite-only SVG).
