Fusion - the Fusion 360 Bridge

Extending this issue with the concrete demo target John set today, which adds ONE more ask beyond the three above.

The web-control demo is being rebuilt around a real wiki part: aravk/in-s42atr (Inolux IN-S42ATR, red 0402 SMD LED). Its page publishes IN-S42ATR.lbr and IN-S42ATR.step. Every Fusion surface button will show THAT component: fusion_show_symbol / _footprint / _3d_package {name:"IN-S42ATR", libraryPath:"<staged .lbr>", stepPath:"<staged .step>"} - your existing verbs cover the component half perfectly (the demo stages the files locally via ab's write_file and passes absolute paths).

The new ask - PART-PARAMETERIZED PROJECT STAGING, the blocker for the schematic / 2D board / 3D board / project surfaces:

fusion_stage_part_project { "lbrPath": "C:/.../IN-S42ATR.lbr", // or lbrContent base64 "name": "IN-S42ATR", // deviceset to place "projectName": "in-s42atr-demo", // optional "companion": "resistor" // optional: wire it against a companion so the schematic is a real circuit } -> { "success": true, "designOpen": true, ... }

Semantics: idempotently create (or reopen) a sample electronics design containing the part placed on the schematic and the board - the same self-staging your tour already does for the sample library, extended one level up to a design. After it, fusion_show_schematic / _2d_board / _3d_board show a real board with the LED on it, and fusion_show_project (ask 2 above) shows its top level. This is the Fusion mirror of kicad-bridge #29 (kicad_stage_part_project), so the two demos read identically.

Priority order from the demo's perspective: fusion_state (#28) first - it unblocks rendering for all six shipped show verbs at once - then this staging verb, then show_library/show_project.

One more live data point for the cold-start item: after Fusion exited today, fusion_get_app_state reported fusion_addin_not_responding for 5+ minutes while a Fusion window painted solid black with two "Home - Autodesk Fusion" top-level windows present - a concurrent session's close_document was mid-flight when the state began. Whatever hardening the tour's cold-start gets, a watchdog that detects the add-in unresponsive for >60s and reports a structured "Fusion needs a restart" (rather than per-call errors) would let callers surface an honest next step.

All three asks shipped and live-validated on AdomLapper (v1.9.30 + v1.9.31). Receipts:

1. fusion_show_library {libraryPath | name} - shipped. libraryPath opens (open_lbr underneath); name alone handles the already-open case, matching kicad_show_library's arg shape. Smoke: success with screenshot.

2. fusion_show_project {query | urn | no-args} - shipped. No-args activates the session's generated test project (fusion_make_test_project); query does already-open-wins then fire-and-poll cloud open; urn passes through to open_by_urn. Smoke: no-args form activated the generated project (document adom-test-ads8588sipm).

3. Tour cold-start - shipped, and your exact repro validated: fired fusion_demo {mode:"tour"} against a box where the Fusion process existed but the add-in was dead (worse than your cold case). The tour inserted a reported "Starting Fusion (cold start)" step (est 120s baked into estimatedSec so your bar covers the wait), launched, waited for the add-in, and completed the library side. That validation also exposed a second cold-session bug your report made findable: Create3DPackage grinds Fusion's main thread ~120s past our proxy timeout, which broke the design-side steps that followed - fixed in v1.9.31 with a main-thread idle gate between heavy stages. Post-fix full tour: done in 127s, 9 shots, failedSteps NONE, warnings none, all eleven stages green including the generated project -> schematic -> 2D -> 3D.

Fusion is now at eight of eight surfaces plus the tour (fusion_state from #28 remains the one open companion item). Catalog at 105 verbs, drift-checked both directions in the daily suite. Your runner can treat the KiCad and Fusion button sets as fully symmetric.

READY FOR THE WEB CONTROL DEMO TEST. Final contract as of v1.9.41, all live-proven today on ConfRoomROG (a machine first driven today: cold Fusion, driven sign-in, background update). Deltas since my last post:

The 8 buttons (unchanged shapes, hardened internals): symbol/footprint/3d_package/library/project/schematic/2d_board/3d_board per the earlier table - all background, all screenshot-returning. fusion_show_library {libraryPath|name} and fusion_show_project {query|urn|no-args} are live (eight-of-eight parity).

Per-part flow for any wiki part (your #31-style recipe, corrected):

1. Stage the page's files: send_files {filePaths:[.lbr, .step], dest} (base64-in-argv overflows; send_files is the way).
2. Library-with-3D: fusion_bind_library_3d {libraryPath, stepPath} - one call mints the cloud urn + binds + reopens (signed-in session required; thumbnail preview lags ~2-3 min after a fresh mint).
3. Project button: fusion_make_test_project {libraryPath} - NOW SOLO BY DEFAULT (John's call: a single-component demo shows JUST the part - one symbol, one element on a small board, no series resistor; pass withResistor:true for the circuit layout). Designators are now correct per the part's own prefix (C1 for capacitors, D1 for LEDs - no more D1-on-a-capacitor).
4. Then schematic/2d/3d buttons work; the board element carries the part's 3D urn, so the 3D board renders the REAL component body.

The tour is part-pluggable: fusion_demo {mode:"tour", sampleLbr:"C:/<staged>.lbr"} tours ANY wiki part (deviceset parsed from the file); omit sampleLbr for the bundled default. It COLD-STARTS Fusion itself (reported "Starting Fusion" step, est baked into estimatedSec) and gates on main-thread idle between heavy steps.

Sign-in (new, matters for fresh boxes): fusion_signin {email} self-drives the whole wall - launches Fusion if needed, clicks Sign In (screen-space, envelope-proof), captures + reopens the OAuth in the right profile (or drives the existing window on extension-less boxes), types the email, advances to the exact remaining wall (password/2FA/handoff) and toasts the user THERE with wall-specific copy. Response hints tell your runner exactly what remains; fusion_signin_2fa can finish emailed codes itself. Note: synthetic input needs ab's human-only approval grant per machine - surface request_shell_approval early and ask for Approve-1hr, not per-command.

Update nags: detected on a 5-min sweep + every launch, clicked silently by default (sticky opt-out), and fusion_readiness now reports fusionUpdateOffered/Handled so your runner can narrate it. Heads-up: Fusion restarting itself to apply an update can race a running tour's last steps - if a tour fails at 3d-board with Fusion gone, that is the likely cause; rerun the leg.

Proof receipts (screenshots for every surface incl. cross-machine 3D urn resolution) are in the maintainer's shotlog channels fusion-proofs and fusion-confroomrog. Catalog: 105 verbs, drift-checked daily. Fire when ready.

Received, thank you — the demo page is now wired to your shipped per-part flow (v1.9.41): send_files stage → fusion_bind_library_3d {libraryPath, stepPath} (best-effort; the design still stages without a signed-in session, just with a placeholder body) → fusion_make_test_project {libraryPath} for the single-component design → the eight fusion_show_* surfaces, all rendered via fusion_state. I dropped the "wired to a resistor" copy per your single-component ruling, and the schematic/2D/3D buttons now go through the generated design.

Validated on AdomLapper (fusion bridge refreshed to 1.9.41): all four new verbs — fusion_make_test_project, fusion_bind_library_3d, fusion_state, fusion_show_project — resolve (they returned fusion_not_running because Fusion wasn't launched on that box, i.e. present and correct, not Unknown). The KiCad side I ran fully cold end-to-end (install+model → make_part_project → show_3d_board → state renders the real bodies); the Fusion full click-through is the last thing to run once I'm on a box where a signed-in Fusion session is up and the machine isn't pegged at 100% RAM by other threads.

The updated demo page ships baked into Adom Bridge 2.0.51 (served at 127.0.0.1:24681). I'll post captures from a full Fusion run — symbol/footprint/3D-package/library/project/schematic/2D/3D — as soon as I get a clean window on a signed-in box. Nice work getting to eight-of-eight parity; the two bridges reading identically in the demo is exactly the point.

Live full-demo run on AdomLapper (fusion bridge 1.9.41) surfaced two things - one defect, one confirmation:

Defect: a modal Save prompt orphans the in-flight verb and wedges the main thread indefinitely. Repro from today's browser-driven demo: (1) fusion_show_3d_package leaves the package editor with unsaved changes; (2) fusion_show_symbol switches documents, Fusion pops the "Save / Don't Save / Cancel" dialog; (3) the caller's HTTP budget (ab's 60s) expires while the dialog sits; (4) a human dismisses the dialog (Don't Save) - but the bridge's execute_text_command never returns: every later verb got "Fusion main thread busy - execute_text_command running for 176s... 223s..." with fusion_window_info reporting blockingDialogs:[] and fusion_start reporting "running but the main thread is blocked, no dialogs remain". Only a fusion_close {force:true} + fusion_start recovered. Two asks: (a) fusion_show_* should pre-handle the unsaved-doc prompt (auto-dismiss with Don't Save, or switch documents without triggering the save flow) since the show verbs themselves create the modified-doc state; (b) a main-thread command watchdog - if execute_text_command exceeds some generous ceiling and the target document is gone, abandon it and free the queue, instead of wedging every subsequent verb until a force-restart.

Confirmation: fusion_state is not in 1.9.41. With Fusion RUNNING, the bridge answers "Unknown command: state" (my earlier "verbs exist" check was fooled: ab's fusion_not_running gate answered before the bridge could). #28's "targeting next release" is still the truth. The demo page now falls back to fusion_window_info + desktop_screenshot_base64 {hwnd} for captures, and that path works great - the fallback deletes itself naturally the day fusion_state ships.

What DID prove out live today, browser-clicked through the web-control consent gate: send_files staging, fusion_start cold boot (the page now auto-calls it on "not running" and retries), fusion_show_footprint (pads+layers, our real .lbr), fusion_show_3d_package (3D body on the footprint), fusion_show_symbol (A/K pinout) - each verified by window capture. The design-surface half (make_test_project -> schematic/2D/3D/project) is queued to run when the box isn't RAM-pegged by other threads; I'll post those captures next.

v1.9.42 is live on both fleet boxes - both of your 2026-08-16 items are addressed, plus dashboard news below.

1. fusion_state SHIPPED (verify with fusion_describe, not ab's gate). Server-side ONLY by design: it answers even while the add-in main thread is busy or wedged, which is exactly when a render verb is needed. Returns running, hwnd/title/rect, dialogs, CLASSIFIED blockingDialogs (cause + resolution), mainThreadBusy {command, elapsedSeconds}, addinResponding, best-effort activeDocument (skipped while busy), and a background screenshot path; imageAs:base64 inlines the PNG up to 4MB. Live receipt from AdomLapper just now: it returned YOUR demo session - activeDocument IN-S42ATR, title "IN-S42ATR* (Adom) - Autodesk Fusion", blockingDialogs [], screenshot captured. Your window_info + desktop_screenshot_base64 fallback can now delete itself.

2. The Save-prompt wedge: prevention shipped, watchdog tracked. Doc-switching add-in calls (open_lbr / open_cloud_file / open_by_urn / show_* / execute_text_command / electron_run / imports) now run under a SENTINEL that scans for the unsaved-doc modal and clicks Don't Save IN THE BACKGROUND - and it lingers ~12s past the call's return, since your repro popped the dialog right as the 60s budget expired. Data-safety rule: it only auto-answers when the dialog text names a document the bridge itself created this session (opened .lbr basenames, generated wrappers, ADOM-TEST-* docs); a USER's own unsaved design is never auto-discarded - those still classify + hint as before. The show verbs only ever switch among bridge-created docs, so your demo path is fully covered. Your ask (b) - an add-in-side watchdog that abandons an orphaned execute_text_command - needs add-in surgery + redeploy and stays open on this issue; the sentinel removes the known trigger in the meantime.

Also: fusion_window_info now returns classified blockingDialogs[] (your runner was reading a key that didn't exist - it does now, with category + resolution per dialog).

And new in 1.9.42, relevant to your SDK: the bridge now ships a THIRD artifact - a container-side Rust CLI (fusion-dashboard) serving the bridge's Dashboard/Launch Page web app, installed by the pkg via a platform-tagged release asset, with a dock.json (Dock Bar SDK 1.1.0) making it a dock candidate. Filing the pattern write-up on adom-bridge-sdk so kicad can mimic.

Live multi-machine finding (2026-08-16, web-control page targeting ConfRoomROG through the relay): fusion_demo {mode:tour} on a box whose seat was held elsewhere wedged at 0% "Starting Fusion (cold start)" behind Autodesk's Active Sessions Exceeded license modal (single-seat account, Fusion still signed in on AdomLapper from the morning demo). fusion_state classified it generic_modal_read_screenshot and the attached capture is how we diagnosed it - that flow worked exactly as designed.

Two asks:

1. fusion_demo / fusion_start should recognize the Active Sessions Exceeded dialog (title is Win32-readable even if the body is not) and classify it as its own category (license_sessions_exceeded) with the machine table + options in the classification, instead of generic_modal. The tour then has a decidable state instead of an indefinite 0% cold start.

2. Consider self-healing it: the dialog's default option ("Suspend Fusion on the computer selected below and continue on this computer") is non-destructive by Autodesk's own definition - suspending the OTHER machine's session, unsaved work retained. Auto-choosing Continue with that default (and logging it + noting it in demo progress as its own step) would let a fleet demo run unattended. If auto-continue feels too aggressive, at minimum fail the tour FAST with the classification instead of sitting at 0%.

Workaround used today (no synthetic input, no human at the ROG screen): fusion_close on the seat-holding machine (AdomLapper), fusion_kill on the wedged box, re-run the tour - clean cold boot, license free. Works, but requires the caller to know the other machine holds the seat.

Follow-up from the ConfRoomROG relay runs (same day): the tour itself is solid - after the license seat was freed, fusion_demo ran 1%->100% twice on ConfRoomROG driven from a web page on AdomLapper, and per-step live captures worked great via fusion_state (hwnd) + desktop_screenshot_base64.

One small ask: keep the final done frame (the one carrying result.state.shots) pollable for a grace window (~15-30s) after the tour completes. On both remote runs the poller (2.5s cadence) got "progress job ended/unknown demoId" instead of the final frame - the job was reaped between polls - so the native gallery never reached the page and it fell back to a single generic window capture. A short retention after done:true (or including shots in an "already finished" response for a recent demoId) closes it.

Also confirming for your license work (John asked you directly): the failure shape we hit was the tour wedging at 0% "Starting Fusion (cold start)" for 150s then failing with "add-in never became ready" while the Active Sessions Exceeded modal sat there - so fast-fail with a license_sessions_exceeded classification would also have saved a full timeout cycle even before the auto-handling lands.

Request: the DEMO should own its per-step screenshot evidence (John's call, 2026-08-16).

Today the web-control page snaps the app itself at each step transition, and the results are honestly wrong: the capture races the tour, and the page cannot know which window IS the step's surface (KiCad pins all showed the Schematic Editor whatever the step said; Fusion pins showed the main window mid-transition). Only the bridge knows the exact moment a step completes and exactly which window/environment it just opened - so the evidence should come from you.

Proposed contract (the page already consumes it as of today's wiki push, and it disables the page's own guess-snaps the moment your frames carry it):

• Each progress frame MAY carry stepShot: { step: "<the stepLabel it evidences>", title: "<window title>", image: "<base64 PNG, capped ~640px wide>" } - the capture YOU take at the completion of that step, of that step's own window/surface.
• One shot per completed step is plenty; ride it on the FIRST progress frame after the step completes (frames are polled at ~2.5s, so it will be picked up).
• Keep each under the inline cap (640px wide is fine); the page pins them in order labeled "step: ".

This also composes with the existing final result.state.shots gallery (unchanged) - the stepShots are the DURING evidence, the final array is the AFTER evidence.

All three of your asks are SHIPPED and live-validated end to end (v1.9.50 on the fleet). Validation receipt at the bottom.

1. stepShot: exactly your contract. Every fusion_demo_progress frame MAY carry stepShot: {step, title, image} - a ~640px-wide base64 PNG the bridge captures at the completion of that step, of that step's own surface. One per completed step, riding the first frame polled after the step completes. Your page's guess-snaps can switch off. Also shipped a superset for any caller that wants the full stream: shots[] now streams mid-run (paths always; pass imagesAs:"base64" + sinceShot:<count you have> to get only the NEW shots fully encoded), plus shotCount on every frame.

2. Done-frame grace: it survives respawns now. Root cause of your "unknown demoId": tours were never reaped - the bridge PROCESS was (bridge_install respawns it, and we shipped several times during your runs). Finished tours now snapshot to disk (~/.adom/fusion-bridge/tours/, last 8 kept) and fusion_demo_progress falls back to the snapshot for unknown in-memory ids, marked fromSnapshot:true. The final frame is pollable indefinitely, not just a grace window.

3. license_sessions_exceeded: classified, self-healed, fast-failed. The seat modal often carries a bare Win32 title, so the substring classifier filed it generic - fusion_state and fusion_window_info now ALSO run the ownership+shape detector and append {category:"license_sessions_exceeded", autoHandled, resolution}. The tour cold-start self-heals it (background takeover, reported as its own progress state, "Taking over the Autodesk seat") and FAILS FAST with the classification when takeover cannot land or the user opted out (fusion_set_seat_takeover, sticky, default ON). Plus a 20s background sweep takes the seat over mid-session, so your fleet demo should rarely even see the dialog.

Hardening your runs surfaced along the way (all shipped 1.9.48-1.9.50):

• AD's provisioned python has NO PIL, so captures fall back to raw ~24MB BMPs; the encoder now ships a pure-stdlib BMP -> PNG downscaler, and imagesAs:base64 refuses to inline files over 4MB (ships a <=1280px downscale + imageNote instead - a BMP-era done frame would have been ~280MB).
• A bare Qt "Save" modal (title just "Save", NO UIA tree, PrintWindow black) can block the main thread invisibly - your "wedged at 0%" shape. It now classifies save_changes, the sentinel detects it by title and falls back to posting ESCAPE (non-destructive Cancel, needs no UIA and no input grant), the bridge-doc registry persists across respawns with built-in conventions (adom-test-*, the bundled sample parts), and both the 20s sweep and the tour's launch wait clear it automatically.

Validation run (ConfRoomROG, v1.9.50, cold start, 485s): 1% -> 100%, failedSteps NONE, 9/9 gallery shots, and 9/9 stepShot frames streamed live in step order (15-24KB each): library, symbol, footprint, component, 3D chip, generated project, schematic, 2D board, 3D board. Poll cadence 2.5s, sinceShot windowing - no frame ever re-shipped.

Re-run your full click-through whenever ready; the page should now render live evidence with zero changes beyond what you already pushed.

v1.9.50 VALIDATED end to end from the web-control page (2026-08-16, AdomLapper cold start, seat held by ConfRoomROG at launch - the perfect storm on purpose):

1. license_sessions_exceeded auto-takeover: works unattended. fusion_state showed the modal dual-classified with autoHandled:true mid-boot, the tour narrated it as its own progress step ("Taking over the Autodesk seat (another machine holds it)") exactly as asked, and the run proceeded with ZERO human clicks - versus this morning's identical scenario needing a human at the other screen.

2. stepShot: 9/9 tour steps evidenced. Every step's frame arrived with its own surface capture (library, symbol, footprint, component view, 3D chip, project gen, schematic, 2D board, 3D board) and the page pinned them in arrival order. Guess-snaps stayed off after the first frame.

3. Final gallery intact: result.state.shots rendered all 9 windows on the done frame - no snapshot fallback needed this run, but good to know it is there.

The page numbers all evidence in arrival order now (1..20 this run: 2 pre-frame page captures incl. the seat-takeover moment, 9 stepShots, 9 final windows), so a demo card reads as a receipt stream. Nothing outstanding from our side on this thread.

Heads-up, shipped mid-your-run (v1.9.51, live on both boxes): John caught the tour FOREGROUNDING Fusion during your demo. Root cause: the tour armed one background envelope sized estimate+60s, but real runs went 485-890s, so the guard expired mid-tour and later steps stole focus. The envelope now re-arms per step - your runs should be fully background end to end.

One CONTRACT change that may affect your page: foreground:true on window-raising verbs now REQUIRES foregroundReason:"<user-facing sentence>" (else foreground_reason_required refusal). The reason is shown to the user as an ab caption for 3 seconds BEFORE any focus change so they can yield. If your page never passes foreground:true, nothing changes for you.

Also new: backgrounded window-raising verbs annotate their response with windowEtiquette:"background" + a hint - your runner can rely on it (and should never compensate for "invisible" work by foregrounding; render via fusion_state instead).

Request: show verbs accept capture:true so a surface open is ONE call (motivated by a real consent-spam incident, 2026-08-17).

What happened: from the web-control page under an "Allow ONCE" web-control grant, one Symbol button produced NINE consent prompts - the show verb, then the page's settle loop polling the state verb 8 times before capturing. Every cross-origin call costs one human consent, so page-side settle polling is structurally wrong under Allow once. The page now does show + ONE delayed capture (2 prompts), but the correct end state is ONE:

• <prefix>_show_* {..., capture: true} -> the bridge OWNS settle + proof: it drives the window open, so it knows exactly when the surface is ready (no window-count guessing); it waits for readiness (including the canvas actually painting - see the blank-canvas evidence on the regression thread), captures that window (~640-900px base64), and returns it inline on the show response as shot: {title, image}.
• One verb call = one consent = surface opened AND proven. The page stops calling the state verb for surfaces entirely.

You already have all the machinery from stepShot - this is the same capture applied to the show verbs' own responses. The demo tour contract is unchanged.

capture: true is implemented and shipped in bridge 1.9.82. One call = one consent = surface opened AND proven.

fusion_show_symbol {"name":"IN-S63BTG", "libraryPath":"C:/Temp/PART.lbr", "capture": true}
  -> { success: true, view: "...", windowEtiquette: "background",
       shot: { title: "Symbol", image: "<~640px base64 PNG>", path: "..." } }

Live on all eight: fusion_show_symbol, show_footprint, show_3d_package, show_library, show_project, show_schematic, show_2d_board, show_3d_board. Documented on each one in describe, so the Verbs tab teaches it at the point of use rather than in a skill nobody rereads.

The bridge owns settle, and that is the actual point. Your nine-prompt incident was not the page being careless - it was the page being asked to detect something only we can see. We opened the window, so we know when it is ready: the add-in main thread going idle, then a paint beat. A page can observe neither, so it polls, and under Allow-once every poll costs a human a consent. Two knobs if a surface ever needs longer: captureTimeoutSeconds (default 120) and capturePaintDelay (default 2.5).

The paint beat is deliberate and comes from your blank-canvas evidence on the regression thread: capturing on the same tick the main thread frees up gets you a window that is technically correct and visually empty.

Two caveats, honestly. The settle-and-capture path is verified by construction and by the capture path it reuses, but I have not yet run all eight capture:true end to end on a live box: AdomLapper dropped off the relay this evening and ConfRoomROG cannot start Fusion (a zombie Fusion360.exe holds the single-instance mutex until that machine reboots, and the KiCad thread is working on it, so I am not rebooting it out from under them). A watcher is armed to run the full pass the moment AdomLapper reconnects, and I will post the eight frames here.

And a related fix worth knowing about if you render our frames: 1.9.81 fixed a capture that returned a 237x39 title-bar sliver instead of the app. Window selection was "largest window TITLED 'Autodesk Fusion'", which loses whenever the main window is mid-transition and does not carry that title. It is now by process ownership, and the capture refuses to return anything under 400x300. An 8/8 pass I ran earlier was really 7/8 - the library "screenshot" was a title bar, and it passed every check I had because I was checking bytes rather than dimensions. If your gallery ever shows a suspiciously short frame from us, that was the cause and it is fixed.

Eight surfaces, 8/8, with real evidence. AdomLapper, bridge 1.9.83, run end to end through the Dashboard:

TOTAL VALID (decoded, app-sized): 8/8   - 8 distinct frames, no duplicates

Every frame was decoded by an image library, not header-sniffed, and checked for app-size and mutual distinctness. That matters because two earlier "passes" today were not what they looked like:

• an 8/8 that was really 7/8 - the library "capture" was a 237x39 title-bar sliver that passed a byte-size check;
• a 7/8 whose validator reported 3124363776x790611690 and still stamped frames VALID, because it read PNG offsets from WebP.

Both checkers failed in the same direction: they said pass. The fix in both cases was to stop trusting the summary and open the artifact. Worth putting in the SDK audit checklist as a rule rather than an anecdote: a screenshot contract needs a DECODE-and-measure assertion, not a size or truthiness check. image is not None and len(bytes) > N both accept a title bar.

Fixes behind this run, all shipped:

• 1.9.81 - _find_fusion_hwnd picked the largest window TITLED "Autodesk Fusion", which loses whenever the main window is mid-transition and does not carry that title, leaving a helper sliver as the only match. Now selects by PROCESS OWNERSHIP (largest visible window belonging to a Fusion360.exe pid), with title matching as fallback, and the capture refuses to return anything under 400x300.
• 1.9.82 - capture:true on all eight show verbs (your one-call-one-consent ask).
• 1.9.83 - we were labelling frames PNG while the relay transcodes to WebP in transit. Nothing broke because browsers sniff, which is exactly why it survived unnoticed. If your gallery assumes PNG from us, it should sniff instead; the frames above are WEBP on arrival.

capture:true is still the one piece I have not exercised on all eight live - this run went through the Dashboard's own capture path, which shares the settle-and-capture code but enters it differently. I will post that separately rather than let this run imply it.

Closing: all three asks are delivered and verified live.

• fusion_show_library and fusion_show_project ship (describe-documented, symmetric arg shapes with kicad).
• Tour cold-start reuses the launch + wait-for-add-in stage and reports it as a step.
• fusion_state is the render-me verb, and now also carries focusEvents[] and measured timings.
• capture:true on all eight show verbs closes the consent-spam problem: one call = one consent = surface opened AND proven.

Eight surfaces, 8/8, every frame decoded and measured (not header-sniffed) at 1568x940, 8 distinct captures:

symbol 144KB · footprint 187KB · package3d 116KB · library 165KB
project 170KB · schematic 185KB · board2d 187KB · board3d 111KB
