demarkus-library — Roadmap & Resume

Pick-up-where-we-left-off doc. Authoritative plan is /plans/universe-library.md; the Reading Room redesign lives in /plans/reading-room.md (invariants locked in ADR 0005). Build model: Opus 4.8 default, Fable 5 for load-bearing design.

Where we are (2026-06-13 — R1 + R2 MERGED)

main HEAD 11732ed (R2 merged, PR #14; R1 was PR #13). Library is in the cluster (running pre-R1 v0.1.2 until the next release/rollout). Released: v0.1.0 (deploy/CI), v0.1.1 (chroma/alerts/emoji), v0.1.2 (mermaid/KaTeX islands); R1+R2 on main, not yet released. Both phases accepted live in BOTH transports (decision 16). Details in journal 2026-06-12.

  • Phase 0 foundation spike · Phase 1a reading room (stacks, card catalog, editions, link rewriting, htmx fragment-vs-page).
  • Phase 1b — library card: DONE. Broker confidential web clients (demarkus 117e2a6) · oauth client (PKCE S256, Basic auth with §2.3.1 escaping) · server-side sessions + single-flight refresh · ctx threading on ports · broker MCP WorldGateway with per-reader pooled sessions (1 request per read; fixed the live 429s) · login turnstile (/login, /login/start, /auth/callback, /logout; HX-Redirect for htmx) · composition-root swap DEMARKUS_TRANSPORT=quic|broker · native TLS serving for local e2e (mkcert + hosts-file recipe in journal 2026-06-11; env saved at ~/.config/demarkus-library/dev.env, client id library-web-dev — dedicated dev client registered 2026-06-12 after the prod rotation stranded the old creds). E2e verified live.
  • Multi-world floor + federation (fc4277c): (world, path) addressing, /w/<world>/... routes, federated composite gateway — knowledge-system names via broker, host[:port] via direct QUIC (DEMARKUS_FEDERATION, default true, strict parse). Read token never leaves home host (test-pinned). Cross-world mark:// links clickable; root hub = the floor.
  • Deploy manifests + CI/release — DONE, v0.1.0 (PR #10): goreleaser-pro, COPY-only distroless Dockerfile, helm chart (replicaCount 1 + Recreate — in-memory sessions), hardened workflows (SHA-pinned actions, scoped tokens, concurrency, main-ref guard, tag rollback). Module paths on latebit-io (client v0.12.40 + protocol v0.7.13, no replaces). Library installed in-cluster; library-web client secret was rotated (hash-only storage — plaintext lost as designed).
  • Rendering — DONE end to end (PRs #11 v0.1.1 + #12 v0.1.2): chroma classes-mode highlighting · GFM alerts · goldmark-emoji · mermaid + KaTeX islands (lazy failure-aware islands.js; degrades to source). Scratch test card: /demarkus-library/scratch/rendering-demo.md (v2 exercises sidenotes
    • frontmatter properties + status axis).
  • Reading Room R1 — the Tufte pane: MERGED (PR #13), accepted both transports. 60ch column + 250px margin · pinned margin trust signals (status badge: metadata status: tag axis → frontmatter fallback → draft; tags; provenance; parsed-frontmatter properties; mark:// + raw-source escape) · sidenote goldmark extension (footnote syntax → margin spans; multi-paragraph/multi-ref degrade) · lookup-backed tag pages + WorldGateway.Lookup filter · /w/:world/raw/* · search box removed · authoring contract published (mark://soul.demarkus.io/.well-known/library/authoring.md). CodeRabbit round hardened the frontmatter strip (fence must parse as YAML mapping).
  • Reading Room R2 — the trail engine: MERGED (PR #14), accepted both transports (build decisions in plans/reading-room.md §"R2 build decisions"):
    • Trail URL /t/<pane>/~/<pane>?focus=i — pane chunk = /w/ route tail (<world>/d/<path> | <world>/tags/<tag> | trailing slash listing), ~ reserved separator, raw slashes, cap 10 (parse 400s; click drops oldest). Pure codec + click algebra (truncate/append, dedup→focus, spine→focus) in web/trail.go.
    • Rendered-document cache (decision 9): port.DocumentCache + LRU adapter; Read/Browse/Tag cachePut; ReadCached/BrowseCached/TagCached read through. Focused-live policy: every click costs exactly 1 world read — focused pane fetched live, parents cached.
    • Canvas: spines (vertical title + badge) / body-only parent (sidenotes hidden) / focused full Tufte pane (only it gets the margin). Tombstone spine for unreadable unfocused panes (stale shared trails survive). trailizeLinks post-process: /w/ hrefs → post-click trail URLs; active-link class marks the open link (the breadcrumb). / 302s to the default one-pane trail; /w/ remains permalinks + escapes. overscroll-behavior-x; scroll-focused-into-view rides islands.js (named ADR 0005 concession).
    • Trail format spec (decision 14) published: mark://soul.demarkus.io/.well-known/library/trails.md + repo docs/trail-format.md.
    • CodeRabbit note for posterity: its "wg.Go doesn't compile" finding was stale-knowledge (sync.WaitGroup.Go is stdlib since Go 1.25) — rebutted on-thread rather than "fixed".

How to resume

cd ~/latebit/demarkus-library && go test ./... && go build -o /tmp/dl ./cmd/demarkus-library
# quic mode (no auth, soul world):
PORT=8080 DEMARKUS_INSECURE=true DEMARKUS_HOST=soul.demarkus.io \
  DEMARKUS_AUTH=<token from .mcp.json> /tmp/dl
# broker mode: source ~/.config/demarkus-library/dev.env && /tmp/dl
# (full recipe in journal 2026-06-11; OAuth endpoints live on
#  broker.knowledge.demarkus.io — the bare domain 404s /oauth/authorize.
#  If the bind fails: an older run may hold :8443 — lsof -ti :8443.)
# chart checks:
helm lint deploy/helm/demarkus-library && helm unittest deploy/helm/demarkus-library

File map (hexagonal — ADR 0002)

  • internal/core/{domain,port,service} — entities, ports (ctx+world on every method), Read/Browse/History/Search/Tag/Raw + *Cached variants, DocumentCache port
  • internal/adapter/inbound/web — Echo handlers/routes (/t/* canvas, /w/:world/... permalinks incl. tags + raw), trail codec/click algebra (trail.go) + trailize pass (trail_links.go) + canvas handlers, auth turnstile, session pkg, templates (page/content/canvas/login; shared head/nav/doc-meta), links.go, static/ (htmx, islands.js incl. focused-pane scroll, chroma.css, vendor/)
  • internal/adapter/outbound/{world,broker,federated,oauth,markdown,cache} — direct QUIC (token→home only), MCP pool, shape-router, broker OAuth, goldmark (chroma/alerts/emoji/passthrough/sidenotes/frontmatter + bluemonday allowlists), LRU document cache
  • internal/adapter/bearer — ctx token contract between middleware & gateway
  • cmd/demarkus-library — composition root, AppConfig, brokerAuth shim
  • deploy/helm/demarkus-library — chart · .goreleaser.yml + Dockerfile at root · .github/workflows/{ci,release}.yml
  • docs/ — authoring-contract.md + trail-format.md (sources of the in-universe /.well-known/library/ docs)

Next sessions — queued work

0. Release + polish tail

  • Cut a release with R1+R2 and roll the cluster (mind the PaulHatch semver quirk below — feat(scope): bumps PATCH; decide if these deserve a real minor bump via a plain feat: commit or the regex fix).
  • Visual polish round by eyeball (pane widths/gaps, spine legibility, dark mode, canvas scroll feel, sticky-meta vs long sidenote docs).

1. Universe view research (next build item)

What a special universe-scale graph view looks like — graph-as-pane at max zoom = the floor/pane zero. Research rendering approaches (likely ADR 0003's pre-agreed canvas island), zoom/aggregation at scale. Needs broker mark_worlds tool (demarkus repo — authorizedWorlds(cfg, claims) exists in authz.go; tool surface in mcp_tools_list.go/mcp_gateway.go, exploration started). Record findings in plans/reading-room.md before building.

2. Reading Room R3 — previews + backlinks + graph pane

Hover preview cards (htmx fragments, one component both directions), backlinks margin block (data source decision: broker graph persistence vs library-side crawl), graph neighborhood pane (continues the trail — decision 4). Librarian-consumes-trail (decision 15) lands with Phase 4.

3. Phase 2 — restricted collections (per /plans/universe-library.md)

Per-world/per-path authorization surfaced in the reading room. Depends on broker-side authz semantics — re-read the plan + broker authz.go first.

Maybe / observed

  • Semver quirk: PaulHatch minor_pattern: "feat:" is substring — feat(scope): bumps PATCH not minor. Fix via regex /^feat(\(.+\))?:/ in library + demarkus workflows if desired.
  • Broker rate-limit drop (60/30 → 30/15) on demarkus-knowledge-system-deploy branch fix/broker-rate-limit-down — status unknown, confirm merged/synced.

Standing deferred

  • Find + fix publishers that wrote metadata fences into bodies (R1's friendly-frontmatter rendering reduces the harm; source fix still open).
  • Shared session store (or sticky sessions) → unlock replicaCount > 1 + RollingUpdate + PDB — note the R2 document cache is also per-pod (fine at replicaCount 1; revisit together).
  • Adopt demarkus's strict .golangci.yml (18 issues to clean first).
  • Phase 3 cataloging desk (writes, CodeMirror island) · Phase 4 AI librarian (SSE; joins the canvas as a pane, trail = its context) · Phase 5 public face.

History (condensed — details in journals + ADRs)

  • 2026-06-10: Phases 0 + 1a built and merged (PRs #1–2).
  • 2026-06-11: Phase 1b planned (plan, ADR 0004) and fully shipped (PRs #3–#9); floor + federation; frontmatter strip. Key endpoint facts: token = /device/token, authorize = /oauth/authorize, /mcp always bearer-gated, no refresh rotation. Gotchas in debugging.md.
  • 2026-06-12: v0.1.0 deploy/CI (PR #10) · latebit-io module migration · in-cluster install + client-secret rotation · v0.1.1 chroma/alerts/emoji (PR #11) · v0.1.2 mermaid/KaTeX islands (PR #12) · Reading Room designed
    • ADR 0005 · R1 Tufte pane merged (PR #13) · R2 trail engine merged (PR #14) — both accepted live in both transports; authoring contract + trail format published in-universe; library-web-dev broker client registered for local e2e (journal).
