v0.2.0 tag pushed → release.yml ran green on the first real attempt with the new NPM_TOKEN → @nynb/sandpaper@0.2.0 is on npm, WITH a verified SLSA provenance attestation (npm view @nynb/sandpaper@0.2.0 dist.attestations) → a GitHub Release was cut automatically. Push order needed a merge, not a rebase — main had drifted from the two Dependabot squash-merges; rebasing would have orphaned the already-pushed v0.2.0 tag's commit, so merged instead. One real bug found and fixed: the changelog-extraction awk step silently never matched (a -v backslash-escaping pitfall — l-awk-v-escaping), so v0.2.0's release notes shipped wrong; fixed the workflow AND retroactively corrected the live release via gh release edit. Both Dependabot PRs merged. Noticed the GitHub Release itself reports immutable: true already.v0.2.0 →/sandpaper:release for real, the first time — the owner confirmed a MINOR bump (a whole new command + verify-publish.js shipped since v0.1.0, not just fixes): drafted CHANGELOG.md's [0.2.0] section from the actual diff, about to run npm version minor + push --follow-tags to test whether release.yml can now publish with the fresh NPM_TOKEN.CHANGELOG.md →NPM_TOKEN. Separately: Vercel Web Analytics added to site/ only — a plain deferred <script> tag pointing at Vercel's /_vercel/insights/script.js (the vanilla-HTML equivalent of the Next.js <Analytics/> component, since site/ has no bundler to import that into), deliberately not added to brain/ — that's generated boilerplate shared by every Sandpaper install, not this repo's to instrument on other users' behalf. Owner still needs to flip "Web Analytics" on in the sandpaper-site Vercel project (Analytics tab → Enable) for the script to have anywhere to report to.site/index.html →/sandpaper:release drafts notes + a semver bump from this very log, writes CHANGELOG.md, runs npm version + push; the pushed tag hands off to .github/workflows/release.yml (test → verify-publish → npm publish --provenance → a GitHub Release). bin/verify-publish.js turns the tarball-safety checks (no site/, no secrets, a size envelope) from manual vigilance into a CI gate on every push (ci.yml, Node 18/20/22); dependabot.yml patches pinned Actions. Also retroactively tagged v0.1.0 at the true publish commit. Caught the CI-publish version of the EOTP wall: an Automation-type npm token is required, not a regular one — recorded as l-npm-automation-token. Owner still needs to add the NPM_TOKEN repo secret before the release workflow can actually publish.D-018 →sandpaper-site → site/, sandpaper-brain → brain/. This commit is the test: a plain git push, no manual vercel deploy, to confirm auto-deploy actually fires on both projects.t-0034 →@nynb/sandpaper@0.1.0 is live on npm. The owner ran npm publish and approved the browser 2FA prompt; the registry briefly 404'd on propagation (checked 3× over ~45s) before resolving — npm access list packages had already confirmed the name was claimed, which correctly predicted it was real. Verified two ways: raw registry metadata (full 0.1.0 version doc, tarball, shasum) and a live npx @nynb/sandpaper help smoke test from the actual registry. Flipped the install command everywhere it's user-facing — root README.md, the live landing (site/index.html, 6 occurrences) — to lead with npx @nynb/sandpaper, keeping the GitHub form as an explicit no-account fallback. Credited as t-0037.npm →sand-paper rejected as "too similar to existing package sandpaper" — an anti-squatting policy npm view never surfaces (l-npm-similarity). Renamed to @nynb/sandpaper per npm's own suggested fix — scoping exempts the similarity check (D-017, supersedes D-016). Tarball re-verified clean (30 files, 69.5 kB). Retried npm publish — blocked on EOTP (npm's 2FA challenge needs a live browser approval; can't complete from a non-interactive run). Owner needs to run npm publish --access public once more themselves.D-017 →sand-paper (owner's pick; sandpaper is taken, v1.4.6). package.json now carries two bin entries (sandpaper + sand-paper, same file) so the CLI keeps its name while npx sand-paper … is guaranteed to resolve. npm pack --dry-run re-verified: 30 files, 69.5 kB, no site/ leakage. The owner doesn't have an npm account yet — account creation + npm login are theirs to do (credential steps); npm publish itself will get an explicit go once they're logged in.D-016 →t-0012 (theme.css single skin — brain imports it, toolbar reads its tokens; docs stay archival), t-0013 (/sandpaper:theme exists), t-0014 (the contract + plan ops + lens rules live in CLAUDE.md/SKILL.md); and the blueprint identity (D-015) shipped with no task — credited as t-0036. Phase 1: 55% → 71% (15/21), overall 33/40 · 83%. Landing proof stats trued up (15 · 17 · 33/40 · 63).the plan →?v=2 + explicit twitter tags), and the canvas is now a recessed drafting-table band inset in the sheet (fixes the standout the sheet move erased). REJECTED: “never out of sync” (overclaim), drag&drop (unshipped, P1), canvas-as-dev-only (it's content, not capability — and the landing's proof). Privacy → q-privacy + t-0035 (publish preflight). Uncommitted — under owner review.q-privacy →site/, sandpaper-brain ← brain/), domains attached with zero registrar work (the domain was Vercel-registered, NS already Vercel's). Production-verified the resolver on the live detached brain: out-links rewrite to GitHub at click time. Redeploys are manual (vercel deploy --prod --yes --cwd …) until git integration is wired; npm still waits on a name.sandpaper.sh →footer selector leaking 56px into every board, an 86px plan-page void, and stale hand-typed dates (the log's day divider is now derived in brain.js). Favicons stripped to the bare mark per the owner. Uncommitted, awaiting verdict.brain.css →theme.css token surgery — 88 lines swapped, one engine fix (plate ref-link used --clay, unreadable on prussian). Fonts → Archivo + JetBrains Mono across every page. The shipped default skin is now blueprint.theme.css →site/ — static, zero-build). Copy chosen by a judged pitch lab (5 angles × 3 blind judges; “artifact” won: “Your repo can explain itself”); signature = a self-stamping hero demo re-enacting w-0193; sections graded P80→P2000. A 4-critic panel (cold-viewer · art-director · copy-chief · a11y) drove 30+ fixes, incl. a hand-tinted stat blocker (proof stats now link into the brain), WCAG contrast tokens, and no-JS visibility. OG card + favicon + deploy guide (site/README.md: sandpaper.sh←site/, brain.sandpaper.sh←brain/).the page →github.com/codevalley/sandpaper and verified the friend flow end-to-end: npx github:codevalley/sandpaper install-skill on a fresh repo scaffolds skill + hooks + brain with the source meta derived from their origin. Post-push polish: fixed a column overrun in the install output, and escaped all target-repo inputs (remote URL · package name) in generated pages — a hostile cloned repo could otherwise inject markup (stored XSS). npm publish stays deferred.the README →brain/ must be always publishable (no build step) — 1 inventory agent + 3 adversarial critics. Measured 158 out-links across 13 pages, 73% anchored spec refs GitHub blob view can't render. Verdicts: write-time absolute dead (kills local-first), publish-step dead (is the banned step), runtime resolver viable — relative links + per-head source meta (blob/HEAD/ + package name) + name-checked probe (no cache) + click-time rewrite. t-0019 reshapes to resolver + stamp-time lint; exporter optional. Boarded as 007.board 007 →t-0019, not removing links. Boarded as 006.t-0019 →LICENSE, enriched package.json (author · repository · homepage · bugs; fixed start), extended .gitignore. Verified npm pack: 30 files, 60 kB, ships only the tool (no brain content or .sandpaper). Blocked on the name — sandpaper is taken on npm (v1.4.6); awaiting the owner's pick. GitHub CLI is authed as codevalley.package.json →SANDPAPER (leading ░ border keeps every row flush; all 38 wide). In both the install output and the /init welcome.setup.js →SANDPAPER where every row is exactly 46 wide, flush at col 2. Applied in both the install output (setup.js) and the /sandpaper:init welcome (init.md).setup.js →install-skill / init / rebuild terminal output marketing-friendly — the ASCII banner, bold SKILL/BRAIN sections with aligned ✓ rows, a prominent ▸ NEXT call-out, and subtle colour that degrades to plain on a non-TTY.setup.js →sandpaper rebuild — a one-command full reset: backs up the old brain to brain.bak-<date>/ (never destroyed), reinstalls, and lays down a fresh multi-page skeleton; run /sandpaper:init to fill it. Alias reset.the README →sandpaper upgrade to bring an existing brain's structure up to date — it now adds any missing skeleton pages (lens pages / books) via the shared writeSkeleton(), alongside the assets/hooks/commands/canvas refresh, and guides you to run /sandpaper:init to fill them. Tested on a simulated single-pager: 1 page → 7, skin preserved.the README →init was inventing structure from prose and collapsing to one page with #anchor nav. Now install-skill scaffolds the full multi-page skeleton (cover + 3 lens pages + 3 books, shell nav wired to relative paths) and the slash command FILLS it. Also swapped the /init banner to the block-char one.the gotcha →/sandpaper:init intro with tighter user-centric copy, an honest ~15–30 min estimate (was “2–3”), a tight close, and the money shot — init now runs open at the end (via the pkg recorded in the manifest) so the browser opens on its own.the command →/sandpaper:init bugs caught while testing: (1) install-skill now scaffolds the package's assets locally, and the slash command is told to USE them and never hunt templates from a sibling repo (it had grabbed productcraft's brain); (2) the go-ahead gate + wizard now use the AskUserQuestion dialog, not plain prose that broke the flow.the gotcha →sandpaper upgrade — brings an existing brain up to the current package: refreshes commands + hooks + engine assets (brain.css/brain.js) while preserving your theme.css, and injects the canvas region into a cover that predates it. Idempotent; tested on a simulated old brain.the README →<details> accordion that reopens into a sheet), capped at five. Designed the stack + a Canvas→Brain two-layer diagram, and boarded the model + “what stamping is” explanation as board 003.the canvas →/sandpaper:canvas command + a fresh-repo empty state, and dogfooded board 001. Lens doors demote to nav below it.why →/sandpaper:init now gates on an explicit go-ahead — a cheap size read + a rough time/token estimate before the heavy harvest, with an offer to scope it down. No more free-falling into the full init.the command →● Claude Code · idle (reads as a tool, not a person), and the ⌖/✎ glyphs became crisp centred stroke SVGs (the crosshair was off-centre and muddy).toolbar →● Claude · idle (drops the redundant Sandpaper wordmark, light readable text, lowercase live states), the ⌖ ✎ >_ icons became one monochrome ink family, and the doubled rule under a .lens-hero card is gone on every lens page (a single .lens-hero + .zone CSS fix). Verified live.toolbar →/ redirects to the brain + ports auto-bump past conflicts, and refreshed the cover's lens-cards to current/parallel content. Verified live (Playwright).gotcha →install-skill now auto-wires the hooks (preserves existing settings, dedupes by command), /sandpaper:init gained an intro + closing summary, the on-page first-run tour ships, and the floating toolbar adopts the host theme.css at runtime so a re-skin reaches it too.gotcha →npx sandpaper CLI (install-skill · init · doctor · open) + src/setup.js + the .sandpaper/manifest.json; tested end-to-end on a fresh repo (doctor ✓ healthy), idempotent, npm-pack clean at 45.5kB.how →/sandpaper:init smarter — wide artifact discovery (classify specs/logs/docs by content, not filename) + an interactive wizard (fill discovery gaps + shape which lenses/books/theme the brain holds).the plan →/init on a cold throwaway repo (linkrot) via a fresh subagent — it found 2 real bugs and generated an accurate brain; the friction (no spec / no count-engine / no manifest) is the Initiative G spec.verdict →/sandpaper:help (the grouped command index) + /sandpaper:open (start the server + open the brain) — 11 commands now.the skill →/sandpaper commands (stamp/init/plan/decide/learn/log/sync/serve/theme) and enabled the auto-update hooks — the Skill initiative is done; we now run on our own skill.the skill →SKILL.md; hooks are opt-in.how →theme.css (55 tokens); brain.css imports + consumes it, toolbar self-scoped.why →
