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 (2026-06-12 late — v0.1.2 on main, R1 on branch)

main HEAD 1f68dac. Library is in the cluster (Fritz installed 2026-06-12). Released: v0.1.0 (deploy/CI), v0.1.1 (chroma/alerts/emoji), v0.1.2 (mermaid/KaTeX islands). ADR 0005 accepted. Reading Room R1 (the Tufte pane) BUILT on feature/reading-room-r1, acceptance VERIFIED in both transports — staged, awaiting Fritz's commit/PR. 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 (allowlist built from chroma.StandardTypes; generated chroma.css light/dark) · GFM alerts (gm-alert-callouts, emoji icons, light-dark() palette) · goldmark-emoji · mermaid 11.15.0 + KaTeX 0.17.0 islands (ADR 0003 concessions recorded; ~3.7MB vendored; lazy failure-aware loader islands.js, re-scans on htmx:afterSettle; degrades to source). Scratch test card: /demarkus-library/scratch/rendering-demo.md (v2 now also exercises sidenotes + frontmatter properties + status axis).
  • Reading Room R1 — the Tufte pane: BUILT + ACCEPTED (2026-06-12, branch feature/reading-room-r1): 60ch column + 250px margin (Charter serif, off-white/off-black, booktabs tables) · pinned margin metadata (status badge — metadata status: tag axis → frontmatter fallback → draft; tag links; provenance; parsed-frontmatter properties; mark:// + raw-source escape) · sidenote goldmark extension (footnote syntax → margin spans; multi-paragraph/multi-ref degrade to footnotes) · WorldGateway.Lookup filter arg + lookup-backed tag pages /w/:world/tags/:tag · raw route /w/:world/raw/* (text/plain) · nav search box removed (decision 5) · authoring contract (decision 13) published at mark://soul.demarkus.io/.well-known/library/authoring.md (+ repo docs/authoring-contract.md). Acceptance verified live in BOTH transports (decision 16): quic against soul.demarkus.io; broker via full login through broker.knowledge.demarkus.io with the new library-web-dev client (Fritz click-through 2026-06-12).

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)
# 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
  • internal/adapter/inbound/web — Echo handlers/routes (/w/:world/... incl. tags + raw), auth turnstile, session pkg, templates (page/content/login), links.go, static/ (htmx, islands.js, generated chroma.css, vendor/ mermaid+katex)
  • internal/adapter/outbound/{world,broker,federated,oauth,markdown} — direct QUIC (token→home only), MCP pool, shape-router, broker OAuth, goldmark (chroma/alerts/emoji/passthrough/sidenotes/frontmatter + bluemonday allowlists)
  • 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 — source of the in-universe authoring contract

Next sessions — queued work

0. R1 tail

Fritz: commit/PR feature/reading-room-r1 (staged, accepted both transports). Visual polish round (spacing, dark mode, sticky-meta vs long sidenotes) by eyeball — fold findings into the PR or a fix branch.

1. Reading Room R2 — the trail engine

Stack URL (/t/... path segments, cap 10), canvas + panes + spines, truncate/dedup/focus, active-link highlight, rendered-HTML cache keyed (world, path, version) — HARD REQUIREMENT (rate-limit math in plan), scroll-into-view snippet, overscroll-behavior-x. Catalog-as-pane. Trail format documentation ships with R2 (decision 14).

2. Universe view research (alongside R2)

What a special universe-scale graph view looks like — graph-as-pane at max zoom = the floor/pane zero. Research rendering approaches (likely the 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.

3. 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.

4. 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 in the chart.
  • Adopt demarkus's strict .golangci.yml (18 issues to clean first).
  • Phase 3 cataloging desk (writes, CodeMirror island) · Phase 4 AI librarian (SSE) · 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 · broker rate-limit drop prepped · v0.1.1 chroma/alerts/emoji (PR #11) · v0.1.2 mermaid/KaTeX islands (PR #12, ADR 0003 updated) · Reading Room designed + ADR 0005 · R1 Tufte pane built on feature/reading-room-r1 + accepted in both transports (sidenotes, margin trust signals, tag pages, raw escape, no search box, authoring contract in-universe; library-web-dev broker client registered for local e2e) (journal).

Git / process notes
