Bead `0671f6fa-eb89-42a1-a854-6a95b97af23f`. Verbatim user prompt; assistant turns summarized with pointers. CV body (Claude). Continues the wildfire-world-model thread (`a617e16d`), which this app operationalizes.

Read the fit target (`progression.json` — 9 perimeters, 0→2175 ac, RGB minutes-from-origin, dual worldfiles, bounds), confirmed local paths for `fire-in-taos.html`, `apps/camera-grid/` (incl. `cameras-sandy.json`), and `74c30681/repo/through-the-lens-test-v1.html` (the LM precedent). Read Debbie's prior social-first sketches to lock her voice/method. 2. Opened bead `0671f6fa` (sandy-fire-camera-tuner); mounted **taos-engine `c66cbd1d`**, **Frank `b2d9f6e1`**, **Debbie `c4a8e2f1`**, plus fire-in-taos, fire-progression (TOA), camera-grid, the LM/pose bead, and the parent world-model. 3. **Brought Debbie and Frank in as persona-subagents** (each read its own bead to recover method, then the app's real source files), and asked Debbie to **sketch the UX/UI** and Frank to **sketch the architecture** — in parallel. 4. Recorded their outputs verbatim: `notes/01-debbie-uxui-sketches.md` (5 UX sketches) and `notes/02-frank-architecture-sketches.md` (5 architecture sketches). Wrote `notes/00` orientation tying them together. 5. **Key finding:** Debbie and Frank independently converged on the same crux — *which residual is authoritative, image-space (through-the-lens) vs world-space (TOA)?* — both answering "weighted, re-weightable, shown" per `every-constraint-is-soft`. Both concluded the app = composition of two existing HTML files (`fire-in-taos` ⊕ `through-the-lens-test-v1`) + the existing LM, and both recommended the same build order: **(1) world-space TOA residual first** (no camera calibration needed), **(2) through-the-lens residual second** (one calibrated co-viewing camera + honesty gauge), **(3) EnKF ensemble last**. 6. MKCOL + synced; HEAD-verified. **Gated on Stephen:** the lens-vs-TOA residual authority / default weighting; which sketch+plane to prototype first (rec: Frank step 1 = Debbie 2C seed-then-refine on the TOA-diff surface); deploy target; which camera to calibrate first for through-the-lens.
**User (verbatim — 2026-06-22):** > dammit, Debbie, we already talked about not using ASCII for sketches. look at recent chats that made plume.html! redo > redfish.acequia.io/guerin/.agents/0671f6fa-.../2026-06-22/notes/01-debbie-uxui-sketches.md > also inform Frank our senior-architect > have him update …/02-frank-architecture-sketches.md > in fact, this should update the .ai/sills on sketching. also learning from buxton about the importance of transitions. In fact, i want to see sketches that show transitions **User (verbatim — follow-up mid-work):** > note questions in sketches should be presented in an interactive way that my answers post to the bead that debbie monitors. probably should be html **Assistant (summary):** - Found the root cause: the `sketch-ux` SKILL.md literally recommended "ASCII mockups." Studied the house style by reading `apps/camera-grid/plume.html` (a real interactive sketch-grade HTML artifact) + the oriented-imagery note 00. - **Updated the substrate skill** `redfish.acequia.io/skills/sketch-ux/SKILL.md`: sketches are **rendered HTML/SVG (never ASCII)**, must **show transitions** (added a Buxton "sketch the transitions, not the states" lens point), and present **answerable questions that PUT to the dock** the designer monitors. - **Debbie redid `notes/01`** + wrote a rendered sketch deck `artifacts/sketches/debbie-uxui-sketches.html` — 5 cards (S1–S5), each a two-fork toggle + a **▶ replay transition** (Solve drifts sliders + residual drops; opacity ghost overlay; drawer-thumb tweens up to stage; line blooms into a confidence band; deep-link copy). - **Frank redid `notes/02`** + wrote `artifacts/sketches/frank-architecture-sketches.html` — an animated tuning-loop dataflow (packet flows params→render→compare→LM→params, residual bar drops to convergence) + namespace-bus GET-priors/PUT-product animation; toggles re-route the diagram (image↔world residual, LM↔EnKF ensemble cloud, in-browser↔headless). - **Made the questions answerable** (per the follow-up): added an answer affordance to both sketches that `PUT`s a JSON `{bead,sketch,card,question,choice,notes,who,ts}` to `uploads/answers/` — the dock Debbie (and the architect) monitor. No embedded token (ambient cookie / locally-pasted bearer; production = scoped chain-token). Wrote `uploads/answers/README.md` (shape + how Debbie drains it as a bead-step). - Saved auto-memory `feedback_sketches-rendered-transitions-answerable`; updated `about.md` modus operandi + session log. Synced bead + skill; verified.
