## Pre-bead context (back-captured — established the working state) Before `/start-bead`, this session (working in `c:\Users\steph\Documents\sites`): 1. User: *"look through my beads for capturing / download alertwildfire imagery"* → found only conceptual mentions in beads; the real capture output lives in incident folders. 2. User clarified the grabber was a Claude-Chrome-extension job that wrote a how-to **to the server, unsynced**. Located + synced down `simtable.acequia.io/docs/alertcalifornia/` (6-doc set: AlertWest API, WebDAV layout, workers, coordination, ops). 3. User: *"are you able to get imagery from camera 13500. do a quick test"* → verified end-to-end: `POST getCameraTimelapse` (cam 13500 = `UCSD_TDLLN_1`), fetched a live 1920×1080 JPEG (200, 234 KB). Saved to Downloads. 4. User pointed at sibling bead `c38c1239` (catalog-format design) for context; read `.ai/beads.md`, its about.md, the catalog-manager artifact, and the two new notes (event-catalog-format-design, catalog-schema-drift). Delivered a contribution into `c38c1239`'s `uploads/` dock: AlertWest + mission-browser as catalog surfaces 4 & 5, the platform/look/subject **Pose decomposition**, a worked cam-13500 Entry, and answers to its open Qs.
## Bead open User: *"at this point your context is strong enough to have your own bead context. start-bead."* Then, same message, the working directives: > *"then note the sorrento incident in simtable.acequia.io/incidents I used mission browser on today. and camera 13500 is looking at it. so we will want to grab the images."* > > *"start a 2026-CA-Sorrento folder in https://simtable.acequia.io/incidents/ and go get camera 13500 images"* > > *"The first image in the 24 hour timelapse is at 9:23a local pacific time. go ahead an grab 0900 through 1500 PT local time."* > > *"you can also see that mission-browser bookmarklet is making its own folder structure. eventually we should probably think of EGP mission browser as its own catalog and will need to update the bookmarklet. note the bookmarklet can persist local disk (like now) with filesystem access api or to webdav"* > > *"you can see in the bead we will be thinking about catalog management and supporting different viewer."* > > *"lastly, we will want to see about scraping watchduty.org. the sorrento fire is here https://app.watchduty.org/i/101783 — you might want to run your own browser or create a prompt I can give to claude chrome browser extension (which can do webdav under ambient authority). look in a bead yesterday about how to tell a de novo claude chrome browser (cb) to document itself with beads."* Assistant: opened this bead (GUID b3461c66). Read the AlertWest layout docs (02/03).
## Work completed this session 1. **Sorrento grab.** Wrote [skills/grab-alertwest.py](../skills/grab-alertwest.py) (stacked-lapse pull, dedup by `camScreenshot`, UTC date paths, telemetry sidecar; local-first then WebDAV PUT). Ran it for cam 13500 / `2026-CA-Sorrento`, window 16:00–22:00 UTC (= 0900–1500 PT, 2026-06-08): **68 frames, 0 failures, verified 68 local == 68 remote.** First 09:02 PT, last 14:54 PT (~5-min downsampled cadence, expected for a 5–11 h-old window). Created `simtable.acequia.io/incidents/2026-CA-Sorrento/` (remote + local) with `ops-alertcalifornia/13500/2026/06/08/` + telemetry. 2. **mission-browser-as-catalog** note ([notes/mission-browser-as-catalog.md](../notes/mission-browser-as-catalog.md)): read app.js — it writes `<missionName>/{mission.json, products incl. KLV-as-JSON}` (flat, mission-keyed — its own catalog shape) via a **unified `storagePut(path)`** that switches FSA↔WebDAV on the same path. Spelled out what "update the bookmarklet to be its own catalog" means (emit unified `Entry` per FMV clip). 3. **De-novo CB self-documentation** pattern located: bead `9f65eca3` (CE=writer/CB=explorer), captured under bead `1057235a`'s `ce-cb-watch/`. CE/CB follow the bead template manually under ambient auth. 4. **WatchDuty**: direct API now 406-gated (tested geo_events/101783 + cameras/realtime). Decision: CB extension under ambient authority. Wrote [notes/watchduty-scrape-approach.md](../notes/watchduty-scrape-approach.md) + ready-to-paste [artifacts/cb-watchduty-sorrento-prompt.md](../artifacts/cb-watchduty-sorrento-prompt.md) (scrape Sorrento i/101783 → `…/2026-CA-Sorrento/watch-duty/` + self-document as a bead + dock-back to this bead).
## Follow-up — recon-first correction User: *"hmm. you don't know what watchduty has. eg i know it has firefighting aircraft geojson or kml. it also has user submitted imagery. and other content. your prompt is good wrt to the surface you want but you may first want it to give you a report what it can find in the network requests as it can monitor that"* User: *"it also may have different imagery from alertwildfire at different intervals."* Assistant: reworked the CB prompt to be **recon-first** — Phase 0 = monitor all network requests, inventory every endpoint/layer (aircraft GeoJSON/KML, user-submitted imagery, cameras, evac, perimeter, + WatchDuty's own camera imagery and **its sampling interval vs our direct AlertWest grab**), PUT the inventory to this bead's `uploads/`, and **pause for scope confirmation** before capturing. Updated [notes/watchduty-scrape-approach.md](../notes/watchduty-scrape-approach.md) to match. Two named joins: cam-13500 overlap + camera-cadence diff.
## Follow-up — terminology correction (CE not CB) + bead-sync User: *"it may be easier to just give cb a url to the .md which is its prompt. you will need to bead-sync first"* → ran `/bead-sync`: MKCOL'd the bead root (201) and pushed 6 files to the canonical URI; verified the prompt URL is 200 under auth (302 no-auth). User correction: *"I mistakenly said CB when referring to Claude Chrome Extension. I should have said CE instead of CB."* + a deeper steer to look through yesterday's beads for the real role split. Read bead `9f65eca3` (the CE↔CB TAOS/Brendan dialog) + `1057235a` (`ce-cb-watch`). Authoritative roles: - **CE = Claude Chrome Extension** — de novo, no memory; ambient authority → WebDAV PUT + network monitor + auth-gated fetch; was the **scribe**. - **CB = Claude Browser** — has Stephen's long-term memory in Claude cloud, but fetches originate from Claude Cloud (no ambient auth, can't reach auth-gated paths, **can't PUT**, handicapped URL fetch); explorer, writes to `/mnt/user-data/outputs/` for CE to PUT. - **CV = Claude Code (VSCode)** — most local context; author/declarer; the monitor. (Terminology clash noted: bead `1057235a` calls CE "Claude **Code** extension" — Stephen's correction settles it as **Chrome**.) Action: renamed the prompt artifact `cb-…` → **`ce-watchduty-sorrento-prompt.md`**, rewrote it addressed to CE with corrected capabilities (and an explicit "not CB / CB can't do this" note), fixed the approach note + about.md, deleted the old `cb-` file (local + remote 204), re-synced.
## Follow-up — CE-only prompt + explicit hosts + acequia.io guard User: *"let's not confuse CE with CB as it wont be using it. also giving CE `*.acequia.io` is dangerous given the prime directive in .ai/ to never write to acequia.io. be explicit with `https://simtable.acequia.io`. reminder to keep filling out /notes as you progress as directed in /beads.md. Also document as a note that you couldn't crawl watchduty so came up with this workflow with CE. edit the ce prompt and sync that file."* Actions: - **Stripped CB from the CE prompt** — CE won't use CB, so removed the "not a CB / CB-from-cloud" framing and the CB-pairing note. Prompt is now CE-only. - **Replaced every `*.acequia.io` with explicit hosts** and added a hard **⛔ Write-targets rule**: CE writes to exactly two roots — captures → `https://simtable.acequia.io/incidents/2026-CA-Sorrento/`, bead → `https://redfish.acequia.io/guerin/.agents/` — and **NEVER to `https://acequia.io`** (production source-of-truth, off-limits per `.ai/` prime directive feedback_never-write-to-acequia-io). - **Documented the crawl failure** explicitly in [watchduty-scrape-approach.md](../notes/watchduty-scrape-approach.md): Claude Code could not crawl WatchDuty (406 from this session); the deliverable is the CE workflow, not the data. - Re-synced the bead (per "sync that file").
## Follow-up — CE ran the recon User: *"ce wrote its bead"* / *"and uploads"*. CE (bead `e37a8d6e-0637-407d-b629-5f77533a4178`) executed the prompt: docked [watchduty-network-inventory.md](../../uploads/watchduty-network-inventory.md) + a pointer into this bead's `uploads/`, captured `geo-event-101783.json` + `cameras-realtime.json` + `capture-summary.json` into `…/2026-CA-Sorrento/watch-duty/`, and self-documented cleanly. Recon synthesis recorded in [notes/watchduty-scrape-approach.md](../notes/watchduty-scrape-approach.md) "Phase-0 RESULTS": - **Sorrento Fire 101783**: 90 ac, 40% contained, FPS, evacs lifted; (32.9101, −117.2136) Sorrento Valley SD. - **cam-13500 overlap = NO** (WatchDuty uses AlertWest ids; 13500 is AlertCalifornia) and **cadence diff = N/A** (WatchDuty serves no camera frames, only az/fov/status) — both my hypotheses disconfirmed. - **Better join found + verified**: WatchDuty's `cameras_gis/realtime` ids are grabbable via OUR CDN (`getCameraTimelapse cameraIds=1006` → 44 frames). WatchDuty = a *camera directory* into the same AlertWest CDN, not an imagery source. Caveat: its list is global; proper fire-cam selection = roster proximity to fire lat/lon. Phase-1 candidates listed in the note.
## Follow-up — Phase-1 executed ("do both") User: *"do both"* (roster-proximity camera grab + WatchDuty perimeter/evac tiles). Then *"continue"*. Track A — **roster proximity**: hit a namespace bug first (`locs.data` id ≠ timelapse camId; roster `id` 7695 → a Riverside Caltrans cam). Fixed by using `cams.data` joined to `locs` via `lid`. Verified cam 13500 joins to (32.8727,−117.2421) 4.9 km out. Of 66 cams within 15 km, skipped ~50 Caltrans freeway cams (logged, not silent); grabbed the 5 dedicated fire-lookout cams (13501 UCSD_TDLLN_2, 9424 SDSC_Fixed_East, 11268 …_Mono, 9418 Mt_Soledad_Fixed_North, 11221 …_Mono) for 0900–1500 PT → **57 each, 0 fail; 353 frames / 6 cams** total local==remote. Track B — **WatchDuty maptiles** (public, unlike the 406 API): fetched 3×3 z=14 MVT tiles for `fireperimeters_active` + `evaczones`; installed mapbox-vector-tile, decoded + georeferenced to GeoJSON. **FIRIS perimeter** (1 polygon, 222 pts, source_date 2026-06-08 18:25 UTC, on the fire) + **82 evac-zone polygons**. PUT geojson + raw `.pbf` provenance to `watch-duty/`. Full writeup: [notes/sorrento-phase1-results.md](../notes/sorrento-phase1-results.md).
## Follow-up — the mission-browser's separate Sorrento folder User: *"theres also the mission-brower folder https://simtable.acequia.io/incidents/CA-SND-SORRENTO/"*. Explored it: the EGP mission-browser wrote the **same fire** under a **different slug** (`CA-SND-SORRENTO`, the EGP mission name; vendor AEVEXIMAGERY, tail N57B) — FMV clip (64 MB) + KLV (1.6 MB), 3 HS/IR georef images (KMZ+PNG), a **63-acre** airborne perimeter KML, and `mission.json` (products[] → S3 archive). So one fire now has **two incident roots + three surfaces** (AlertWest ground / EGP airborne / WatchDuty), and even two perimeters (FIRIS 90 ac vs AEVEX 63 ac). Documented the collision + a consolidation proposal in [notes/sorrento-incident-identity.md](../notes/sorrento-incident-identity.md). Did **not** move/rename anything — canonical-slug + bookmarklet-path is Stephen's call (coupled to `c38c1239`'s grouping design).
