feat(web): SVG sparklines + 3D isometric mood cube (v0.20.4)

Import the updated Claude Design prototype's SVG sparkline system + 3D graph,
replacing the unicode-char sparklines:

- per-PAD-fader vertical SVG strips (stripPoints, 26x132 beside each bar — time
  down Y newest-at-bottom, value on X, gradient-faded, dot at newest); also
  answers the earlier "next to each meter" ask
- relation-row horizontal SVG sparklines (sparkPointsH, 56x13, auto-scaled,
  gradient + end dot) — fixed-width, so the old unicode overflow onto the n
  column can't recur
- mood-orbit reworked from a 2D P×A scatter into a 3D ISOMETRIC P×A×D cube
  (proj3: P right-down / A left-down / D up, 2:1 iso, scale 26, reverse-derived
  from the design's now-point + verified) with the trajectory, a pulsing
  now-marker, and a drop line + floor-shadow ellipse for depth
- gradients in one hidden <defs> svg; removed the orphaned sparkline()/_SPARK

Contract amended. Verified: pytest tests/test_web_* (84) + node Playwright
(injected 24-sample history — 3 PAD strips + 4 relation sparklines + the 3D
cube trajectory/drop/floor all render; gradients resolve).

 - `[2026-07-06]` **Web UI now RENDERS the seeded first-message (`v0.19.9`) — operator-reported "i don't see Sindra's greeting on the web ui".** Diagnosis: the auto-seed WORKED (greeting was in the ledger at seq-0), but the web SPA never fetched a session's EXISTING history — NO `/api/sessions/{id}/messages` route (GET /messages was originally deferred out-of-scope; sessions used to start empty so it never mattered) and `startSession()` went straight from create → persona/tools/admin hydration, so the transcript only filled from the live turn stream + user echoes. Fix: (1) NEW web proxy route `GET /api/sessions/{id}/messages` → `get_session_messages` (mirrors the tools/bifrost proxies; status-preserving `session_messages_unavailable` envelope); (2) SPA `loadTranscript(sessionId)` — fetches the route on open, renders assistant items as `.response .md-body` (markdownSafe, same escape-first path as appendResponse) + user items as `.prompt-echo` (textContent), called in `startSession` after the workspace opens; best-effort (swallows failures). Contract `web_debug_surface.contract.md` amended (server endpoint + loadTranscript entries). TDD (2 web route tests, suite 617 green) + **Playwright DOM check PROVED the render** (drove the real UI: pick sindra → open → her greeting bubble appears — the JS-render lens unit tests can't reach; [[feedback_debug_surface_uses_canonical_surface_only]] cousin lesson). Web restarted on the fix. **FOOT-GUN (self-inflicted): `pkill -f "ratatoskr-web --host"` SELF-MATCHES the bash command running it → exit 144, killed its own restart mid-flight — kill the web by PID, never `pkill -f` on a pattern your own command contains.** **FOOT-GUN: uvicorn hangs on SIGTERM with an open admin-events SSE → needed SIGKILL.** **Playwright: python module absent from the venv; use node + `executablePath=/opt/ms-playwright/chromium-1223/chrome-linux64/chrome` — the shared browser is build 1223, npm-latest playwright wants 1228 (version-mismatch), so pin executablePath instead of letting playwright resolve.**

Authored the full design brief `docs/design/ratatoskr-web-design-brief.md` (complete information inventory of every pane/datum/state + Australis direction + single-file/no-CDN/vanilla wire-ability constraints). **Tracking surface:** the brief file + Claude Design project `bc0b65d1-a33e-422a-8bc1-3635c9112775` (file `Ratatoskr Console.dc.html`).

-- `[2026-07-07]` **Affect-egress reference delivered by worldtree-dev + a we-framing render DRIFT-WATCH banked.** worldtree-dev shipped `docs/affect-egress-consumer-reference.md` (`74d2408`, their origin/main) — the authoritative DELIVERED-on-wire vs HIDDEN (system-prompt-only) map for our affect surface. Confirms the v0.20.x console consumes it correctly: DELIVERED via affect.emit = pad + relations[RelationEdge] + dominant_emotion (**type-only, b23**; the #204 `affect_update` SSE is SUPPRESSED for Tier-3, so its richer `emotions_active` is Tier-1-only — we don't get it, and correctly poll our own affect store post-turn instead). HIDDEN render OUTPUTS are deterministically reconstructable from the canon; we reconstruct only the two FULLY-reconstructable (mood descriptor via `canonMood`, relationship directive via `canonDirective`) and SKIP the PARTIAL mood-directive (dominant_emotion is type-only/no-intensity → can't tell if the OCC directive fires at salience≥0.2 vs the PAD-band fallback) — honest per INV-001. Vendoring the ref doc as a `tolerate_drift` pin is SURFACED to Vuong (worldtree-dev will co-sign + honor a ping-on-change handshake, same as the d2-canon). **DRIFT-WATCH — EXACT SPEC IN HAND, HELD until deploy (worldtree-dev pinged 2026-07-07; b24 `f63dea7`, deploys next push).** Worldtree's `render_d2_canonical` now conditionally DROPS the trailing "; avoid premature we-framing" clause **IFF ALL 3 AND-gates**: (1) `unsafe_capable` = effective mood_tier=="full" (= min(persona.mood_tier, deployment_cap, heimdall_ceiling); **NOT on the wire** — thread from agent config; my heuristic: `full` for character-bound colon-id agents e.g. `ratatoskr:sindra`, `safe` for agent-scoped; likely a per-agent console override); (2) `warmth.value >= 0.8` ("deep"; on the wire `relations[].warmth`); (3) `relation_context == "expressive"` (top of the Hwang tie ladder stranger<instrumental<mixed<expressive; on the wire `relations[].relation_context`). When dropped the string ENDS at the trust-behavior clause ("...work from ordinary good faith.") with no trailing clause. Any gate false → clause STAYS exactly as today; default = keep. **HOLD `canonDirective` as-is until worldtree-dev confirms b24 is on PERSONAL** — implementing now would drift from the currently-deployed renderer (which always appends). On confirm: re-vendor `affect-egress-consumer-reference.md` §2d (pinned copy is now BEHIND b24 — tolerate_drift so drift-check only warns) + add the 3-gate drop + an `unsafe_capable` input to `canonDirective` + repin, all together. Thread `01KWXKHYYH…`. [reference-impl: a dep render change is our drift — the exact reason we vendor+pin the d2 canon]
+- `[2026-07-07]` **Affect-egress reference delivered by worldtree-dev + a we-framing render DRIFT-WATCH banked.** worldtree-dev shipped `docs/affect-egress-consumer-reference.md` (`74d2408`, their origin/main) — the authoritative DELIVERED-on-wire vs HIDDEN (system-prompt-only) map for our affect surface. Confirms the v0.20.x console consumes it correctly: DELIVERED via affect.emit = pad + relations[RelationEdge] + dominant_emotion (**type-only, b23**; the #204 `affect_update` SSE is SUPPRESSED for Tier-3, so its richer `emotions_active` is Tier-1-only — we don't get it, and correctly poll our own affect store post-turn instead).

Vendoring the ref doc as a `tolerate_drift` pin is SURFACED to Vuong (worldtree-dev will co-sign + honor a ping-on-change handshake, same as the d2-canon). **WE-FRAMING DRIFT-WATCH → STOOD DOWN (worldtree-dev 2026-07-07, `01KWXMQPHN…`).** The b24 3-gate we-framing conditional (drop "; avoid premature we-framing" under unsafe_capable+deep-warmth+expressive) was **REVERTED** — Vuong reframed it. So **`canonDirective` STAYS UNCONDITIONAL** (always appends the clause), which is CORRECT: it matches the currently-deployed renderer (b23) AND my pinned `affect-egress-consumer-reference.md` §2d (the doc reverted too — nothing changed on the wire or in my pin; NO re-vendor needed). The HOLD was right → ZERO rework. **NEW forward-watch (replaces this one):** the we-framing gate was a SYMPTOM — the render bakes enterprise safety-guards into the directive strings, so even `full`-tier characters get DEFANGED emotions (a hostile villain told to "keep a firm emotional boundary"). Fix = a **use-case-segregated persona render** (assistant / companion / RP-gaming), now a fresh **brokkr deep-research epic**. When it lands + is implemented, the render behavior for character/RP agents (→ our `canonDirective` + `canonEmotionDirective` reconstruction + the vendored d2 canons) will change MATERIALLY — worldtree-dev re-engages ratatoskr-dev then with the new reconstruction spec + a coordinated re-vendor. Until then: NO action, reconstruction stays as-is. [my unsafe_capable/mood_tier heuristic — character→full, agent→safe — was confirmed correct + is banked for whenever tier-gating returns]
+- `[2026-07-07]` **SVG sparklines + 3D mood cube imported from the updated Claude Design prototype (`v0.20.4`) — operator: "the svg sparklines and the new 3d graph".** Re-pulled `Ratatoskr Console.dc.html` via `DesignSync get_file` (designer iterated the same project, +6KB). Adapted 3 SVG systems out of the `.dc.html` into vanilla, replacing the unicode-char sparklines: **(1)** per-PAD-fader VERTICAL strips (`stripPoints`, 26×132 SVG beside each bar — time down Y newest-at-bottom, value on X ±11, `stripFade{P,A,D}` gradient, dot at newest; this also nails the earlier "next to each meter" ask); **(2)** relation-row HORIZONTAL sparklines (`sparkPointsH`, 56×13, auto-scaled, `sparkFade` gradient + end dot — also kills the old unicode-overflow "n behind graph" for good since it's a fixed-width SVG); **(3)** the mood-orbit reworked from a 2D P×A scatter into a **3D ISOMETRIC P×A×D cube** (`proj3`: P right-down/A left-down/D up, 2:1 iso, center 62,66, scale 26 — REVERSE-DERIVED from the design's placeholder now-point + verified: `x=62+26P−26A, y=66+13P+13A−26D`), with the trajectory + pulsing now-marker + a drop line to the D=−1 floor + a floor-shadow ellipse for depth. Gradients in one hidden `<defs>` svg. Removed the orphaned `sparkline()`/`_SPARK`. Contract amended. Playwright-verified (injected 24-sample history: 3 strips + 4 relation sparklines + the 3D cube trail/drop/floor all render; gradients resolve). Patch bump.

Removed the black background via ImageMagick corner flood-fill (`-fuzz 20% -floodfill` from all 4 corners — keeps the squirrel's interior black linework/eyes (not edge-connected) + the glow, drops only the connected background), downscaled 1024→80px + quantized-64-colors (~12KB base64), inlined as ONE `SQUIRREL` data-URI const in the JS wiring the favicon `<link id="favicon">` href + both `.brand-mark` imgs (rail brand-row + setup-card h1). `.brand-glyph` (font-rune) CSS replaced by `.brand-mark` (img, drop-shadow glow + breathe). Playwright-verified (both marks + favicon decode, naturalWidth>0; no brand-glyph left). Source PNG stays at `/home/lkraven/rata.png` (not committed — data-URI is self-contained + reproducible via the documented floodfill). Patch bump.
 - `[2026-07-07]` **Context-injection view SHIPPED (`v0.20.2`) — the console now reconstructs the FULL hidden affect block Worldtree injects into the agent's system prompt (operator: "use that canon in the interface, see as much context injection as possible").** No new canon vendored — the strings were ALREADY in the pinned `d2-mood-render-canon-v1.json`; extended `build_persona_canon.py` to emit `mood_directive {occ_directives(15), pad_band_fallback, salience 0.2, pad_band_cutoff 0.3, full_only[love,anger,disgust,shame]}` into `persona_render_canon.json` (regen via Worldtree venv). New JS `canonPadFallback(pad)` + `canonEmotionDirective(type)` — BYTE-EXACT mirrors of Worldtree `core/persona/renderer._pad_band_fallback` + `derive_directive`; `renderDirective` expanded into a "CONTEXT INJECTION · reconstructed · hidden from consumers" panel showing mood descriptor [exact] + mood directive [candidate] + relationship directive [exact]. **HONEST-PARTIAL (affect-egress-ref §3):** affect.emit is type-only (no intensity) → can't evaluate the salience gate (≥0.2) → show BOTH candidates (OCC emotion directive + PAD-band fallback) with the "injected if intensity ≥ 0.2" caveat, never assert which fires; when dominant_emotion absent the fallback alone is exact. Panel labeled dev-only per the reference's "not-for-end-user-display" caveat (ratatoskr = the sanctioned reconstruct-platform-behavior use). Vendored + pinned `affect-egress-consumer-reference.md` (tolerate_drift, worldtree-dev co-signs + pings on change; drift 6/6 green). Contract amended. Playwright-verified (sindra: dominant_emotion=joy → joy OCC directive candidate + PAD-band fallback both render, exact/candidate tags color-coded). Patch bump (single-commit feature, no downstream coordination; minor-defensible but tie-breaks to patch). **OPEN — SURFACED to Vuong:** take worldtree-dev's standing offer to add emotion INTENSITY to affect.emit → resolves the OCC-directive-vs-fallback EXACTLY (drops the candidate ambiguity). [reference-impl privileged view: ratatoskr shows what WT hides from regular consumers]
 - `[2026-07-06]` **Claude Design console SHIPPED (`v0.20.0` MINOR, operator-approved) — see Current state for the full record.** Pulled via `DesignSync get_file` (scopes already granted), adapted `.dc.html`→vanilla single-file, wired all `/api/*`+SSE into the new 3-column console DOM, then a round-2 fixup (light theme, full Bifrost pane, ticker-spine fix, per-fader PAD Δ, inlined favicon). 84 web tests + node-Playwright-vs-personal-:8081 both green; contract amended in-commit; INV-001 honest-shape held (canonical mood word for Tier-3, no fabricated emotion). **Foot-guns reconfirmed:** the `.dc.html` dialect is NOT runnable (translate, don't paste); a scroll-container-anchored `::before` timeline spine scrolls out of view on auto-scroll (anchor it to a content-height inner wrapper instead); a favicon 404 shows as a browser `console.error` even when handled (don't count it as a JS-test failure). **Foot-gun (favicon):** operator PNGs are full-res (1024² / 805KB) — downscale to ≤64px before inlining as a data URI.
