Bead `a617e16d-2257-40b7-8d30-9cfc5ff452e8` (wildfire-world-model). Verbatim user prompts; assistant turns summarized with pointers. CV body (Claude). This session also opened sibling bead `2aeb9f0b` (world-models) earlier; see its chat log for the LeCun/Hinton + canon work that this bead builds on.
**User (verbatim — opened this bead):** > review beads this week for incident-viewer, STACs of actual fire obsservation from misb aircraft, news, alertwildfire and ciitzen imagery. > > write up world-models technical approach and start-bead wildfire-world-model. mount-bead senior-architect and make initial plans of how to (fuse imagery, measure wildfire behavior, and have a model for their forecasting) **Context flagged:** IDE had `acequia-component.html` (bead `1697e2ae`) open; unrelated. **Assistant (summary):** 1. **Surveyed the ecology.** Launched an Explore agent over `.agents/` — inventoried ~16 wildfire/STAC/camera/engine beads grouped by fuse / measure / forecast. Key data: MISB aircraft FMV (`97559992`, `c66cbd1d`), AlertWildfire PTZ (`65783732`, `b3461c66`), news-heli ADS-B (`2986ff41`, `58c0a5e0`), citizen-imagery pose stack (`edb06426`/`74c30681`/`58091f55`/`09fd1bf6`), STAC catalog (`90f902e0`, `31f69717`), fire-progression TOA raster (`182bd1a7`), fire-in-taos CA (`b6fcda63`). Flagged gaps: no sim-vs-observed validation harness; firewatch-camera-grid not built; no live multi-clock sync. 2. **Found + mounted senior-architect** `b2d9f6e1` (grep over about.md). Read its deliverable: the 5-plane convergence stack (0 data/STAC · 1 UI-shell · 2 time-cursor · 3 engine-kit · 4 namespace-bus), "loosely couple, tightly align." Aligned every plan stage to a plane. 3. **Grounded fire science** via WebFetch of Wikipedia *Wildfire modeling* (Rothermel ROS, Byram fireline intensity, FARSITE Huygens, WRF-Fire level-set, ELMFIRE ensemble, EnKF/morphing assimilation). Note: WebSearch was degraded this session (prose, no links) — ML-fire-forecasting SOTA left confirm-pending. 4. **Started the bead** `a617e16d` (wildfire-world-model) and wrote: - `about.md` — identity, motivation (verbatim prompt), mounted beads, layout. - `notes/00-wildfire-world-model-orientation.md` — frame + ecology map + read order. - `notes/01-world-models-technical-approach.md` — **the writeup.** V/M/C decomposition mapped to fire (V=fuse→latent fire state, M=physics-prior+learned-residual dynamics, C=TOA/intensity/evac readout); why representation-space not generative-video; EnKF assimilation closing the loop; fire-science anchors; mapping to the 5 senior-architect planes. - `notes/02-initial-plans-fuse-measure-forecast.md` — **the three plans.** Plan A (fuse: A1 schema → A2 wire producers → A3 citizen dock → A4 encode-to-grid). Plan B (measure: B1 perimeter-from-imagery → B2 ROS field → B3 intensity/Byram → B4 behavior timeline). Plan C (forecast: C0 validation harness → C1 Rothermel/level-set physics baseline → C2 ensemble+EnKF → C3 learned residual). Build order recommended; worked example = Sandy Fire. - `uploads/README.md`, this chat log. 5. MKCOL + synced to canonical URI; HEAD-verified. **Gated decision surfaced:** drive Plan A / B / C first (recommendation: A1+A2 then C0+C1 for a demoable fuse→forecast→score thread on Sandy).
**User (verbatim — 2026-06-21):** > mount-bead wildfire-forage and bead wildcad as they relate to plan A > > Write up an overarching plan. also mount senior-architect **Assistant (summary):** - Located the two beads: `5b518c35` **wildfire-forager** (umbrella forager *pattern*: detection source → normalized ignition record → fan-out → catalog) and `bd08d6d4` **wildcad** (first source-subscriber; `subscribe-wildcad.mjs` over WildWeb/WildWeb-E dispatch). Read both about.md. - **Mounted** both into this bead's `about.md` as Plan A's detect/forage front-end; re-affirmed the senior-architect `b2d9f6e1` mount. - **Reframed Plan A** (`notes/02`): added stage **A0 — detect** (ignition trigger via wildcad/forager) and rewrote **A2 — forager fan-out** (an ignition record fans out to imagery/ADS-B/media foragers) instead of bespoke wiring. - **Wrote the overarching plan** (`2026-06-21/notes/03-overarching-plan.md`): the end-to-end spine **DETECT → FORAGE → FUSE → MEASURE → FORECAST → SERVE** as one namespace bus with **6 segments** (each an existing bead) and **4 contracts** (ignition record · fused-observation item · behavior raster · forecast product). Key insight recorded: the **forager pattern IS the first built instance of senior-architect plane 4 (namespace-as-bus)**; the world model extends the same bus downstream. Program-level build order (contracts → S0+S1 live → S2+S3 Sandy replay → S4 C0+C1 → C2 loop → citizen+social → C3 learned). 4 gated decisions surfaced (where the spine runs, first live AOI/centers, forward-vs-widen, wind/fuel sources). - Synced + HEAD-verified.
