From e987d831535a175643d21f19c598d977af9c16ca Mon Sep 17 00:00:00 2001 From: tyeth Date: Sat, 29 Aug 2026 20:15:53 +0100 Subject: [PATCH 001/135] Perf: Add startup timing marks across main, server and renderer Startup cost was unmeasurable: nothing between process start, server ready and first paint carried a timestamp. src/startup-timeline.js records named marks against one epoch. Main stamps LUBAN_START_T0 into its environment; the forked server inherits it and the renderer reads it off window.process, so marks from all three processes are comparable. Each prints one ordered table at the end of its own startup. Lives at the top of src/ so every entry point reaches it with no build change - src/*.js is babel-compiled for main, and both webpack bundles resolve ../startup-timeline. No behaviour change.

The window loaded app/loading.html and only navigated to http://127.0.0.1: once the forked server reported ready, so the user watched a GIF for however long the fork took - 1.6s warm, 12-26s cold. The luban:// handler already serves app/** off disk, so the window now navigates straight there. The protocol registration, @electron/remote and the proxy config move ahead of the first load into prepareAppEnvironment(); startToBegin() keeps only bookkeeping. That makes every API call cross-origin, so the server answers CORS for luban:// origins - including the OPTIONS preflight superagent forces by sending Authorization and Cache-Control - and socket.io gets the cors option v4 requires. Three things the move exposed: - the scheme was registered without supportFetchAPI, so i18next's requests never reached the handler and always hit the 3s cap - express mounts the app directory at both / and /worker, so worker URLs arrive with a prefix that is not on disk; the handler now strips it, and reports a missing file rather than returning a stream that throws - components call the API as they mount, about a second before the server origin arrives, so those calls resolved against luban://. defaultAPIFactory now holds each call until the origin is known First paint 3275ms -> 1503ms warm, and now precedes server-ready rather than following it.

DataStorage's constructor logs from module scope and createServer() logs as its first statement, so the gap between those two lines is pure require() of ./app and ./services. Across 15 launches of my own log that gap was 12-24s cold and ~0.6s warm; a cold run of this branch's parent measured 26.6s. Nothing above the listener needs either module. The port now binds on a bare http.createServer whose handler parks requests, the ready callback fires immediately, and express, the machine channels, the slicer and the task workers load on the next tick. Parked requests are replayed once the app exists, so the gap refuses nothing. DataStorage.init() moves into the deferred block too - it must run after app.js, which installs the process-wide unhandledRejection handler that its floating font download relies on. The startup table prints at 'ready', which is now before all this, so the deferred phase reports its own line. Warm: bundle required 1081ms -> 369ms, server ready 1764ms -> 982ms, services ready at 1711ms and off the critical path.

Behind a VPN or offline the online-resource proxies never answered. All five logged the error and returned without touching res, so the renderer's XHR stayed open until the socket gave up. They now carry a 5s response / 10s deadline timeout and always reply, 503 on failure. getUserInfoData also stops calling agent.use() per request, which accumulated Authorization plugins on the shared agent and leaked whichever token was set last into unrelated calls. downloadManager had no timeout and no catch, so an unreachable font or calibration map left a floating rejection. It now aborts at 15s and resolves a boolean - callers treat these as best-effort. whenBackendOrigin() was unbounded, noted as a known gap in #18; it now rejects after 30s so API calls fail rather than queue for ever. CaseResource ran an access probe with no timeout at all, leaving a blank frame until its 60s iframe timer fired. Bounded at 2s, matching the home page probe. It was also mounted unconditionally and merely hidden with display-none, so every launch loaded an iframe from resources.snapmaker.com even for users who never open the Library; it now mounts on first open and stays mounted after. The home page says so inline - an empty grid with a label above the local examples - rather than popping a dialog.

Sentry.init ran at module scope, before app.whenReady, on every launch: 21 integrations, the Electron crashReporter, four OpenTelemetry globals and a read of its offline envelope store - all ahead of the first window, and all useless to someone offline or behind a VPN. Nobody opted in. It is now required and initialised only when the stored enableCrashReporting flag is set, which defaults to false. debug: true is dropped from the shipped config. electron-updater was imported at module scope and updateHandle() wired its listeners during startup, though nothing checks for updates until the renderer asks 200ms after mount. The wiring moves into wireAutoUpdater(), called on first use. node-fetch is likewise required where the changelog is fetched, its only caller. The flag is exposed as a Settings > General checkbox and a Settings menu item, both stating it applies on next start, backed by get/set-crash-reporting IPC. Main reads the store before any renderer exists, so the store is authoritative. Warm, same profile: app ready 497ms -> 76ms, first paint 1413ms -> 1055ms. Startup log drops from 106 to 69 lines.

Every frame is stamped with the firmware-reported position it was taken at. move_and_capture performs one bounded XY move at the current Z via the direct path - no Z parameter by design, Z and compound motion go through submit_gcode_job per #23 - waits for two settled heartbeats at the target, then captures. Guards: idle machine, toolhead off, per-call travel limit (mcpMaxJogDistance), build-envelope check in machine coordinates. The transport now passes tool-supplied MCP content through, so frames return as image content rather than JSON text. Closes #10. Closes #11.

Deriving the matrix stays the agent's job; the store keeps it. Closes #13.

Luban homes as G53;G28;G54 - a bare G28 leaves positions reported in an unselected workspace, which was the source of the impossible derived machine coordinates (Y 464/Z 656). - home now sends the same G53;G28;G54 sequence as Luban's button and warns that G28 also homes B (stock on the rotary rotates; observed -45 to 0 on hardware). - Every direct-path gcode an MCP tool sends is mirrored to the verbose console with the controller reply ([mcp:home] > G28 / < X:...), so the operator can see which coordinate frame each command ran in. - New query_firmware_position tool returns the raw M114 response alongside the heartbeat view - the authoritative frame check.

Rewritten around the Luban MCP surface (position-stamped capture, guarded single moves, Y/Z-keyed calibration store, one-step visual_servo, M114 frame check, human-gated jobs) and the machine semantics verified on hardware since: G53/G54 workspace model, home = (-19, 342, 328) via G53;G28;G54, origins persist across homing, toolhead-mounted camera with the platform moving under it in Y, rotary homes with G28. The vision core is unchanged and board_metrology.py is bundled. The skill degrades gracefully to the hand-relayed workflow when no MCP is live. A project-scope .mcp.json at the repo root points sessions at the local MCP endpoint (127.0.0.1:40889/mcp), so agents working in this repo get the luban server without per-command --mcp-config flags.

Direct moves now parse the absolute Z target from the executed gcode (G53 wrap selects the frame) and the settle loop waits until the reported Z matches within 0.15mm; home requires the position to move off its pre-G28 value at least once before accepting stability (25s fallback when starting at home). On timeout the position is returned with position_verified: false and a warning naming query_firmware_position - never silently. XY moves already verified against their target.

Bundle the pure-JS dependencies into the server bundle instead; only packages that cannot live inside a bundle stay external: native addons (serialport, font-scanner, lzma-native), packages that spawn or load sibling binaries/assets from their own package directory (snapmaker-lunar, snapmaker-luban-engine, opencv-wasm, errorhandler, formidable, socket.io serveClient), and template engines resolved by name at runtime (consolidate, hogan.js). Measured on the same machine: services-ready 9766ms for the first launch of the unbundled build vs 736ms launching the bundled build from a fresh folder of never-scanned files.

checkout token falls back to github.token when SACP_TOKEN is absent (the submodules are public repos, checkout rewrites their ssh URLs) - notarize.js skips notarization when APPLEID/APPLEIDPASS/TEAMID are not configured instead of throwing; electron-builder already skips code signing when CSC_LINK is absent, so macOS packages build unsigned -

Scan only src/*.{ts,js} and src/electron-app for main-process imports, add electron-updater and node-fetch explicitly (lazy require()s inside functions in main.js, invisible to the top-level import scan), and add the server externals mirroring KEEP_EXTERNAL in webpack.config.server.production.js. formidable and encoding are pinned outright: their former parents (superagent, node-fetch) are bundled now, so they are no longer installable as transitive deps. A clean 'npm install --omit=dev' of the manifest drops from 20726 files / 264MB (~404 packages) to 13392 files / 168MB, and every bare require() in the built dist artifacts was verified to resolve against the pruned install.

This adds the transport: a hand-rolled minimal MQTT 3.1.1 client over net/tls (zero new dependencies, same rationale as the MCP transport itself - Node 16), verified round-trip against public brokers on both plain TCP and TLS, and a ProbeFeedService that resolves configuration environment-first (LUBAN_MCP_MQTT_*) with the configstore as fallback, editable in a new Settings -> MCP Server section (password never echoed back). Feed channels: toolsetter, overtravel, probe. Topics accept an Adafruit IO feed key ({user}/feeds/{key}) or a full topic path; on Adafruit IO hosts the last value is primed via /get. The client id defaults to username + MAC bytes. Per-channel polarity: the Inverted setting lists channels whose sensor idles HIGH and reads low on contact (normally-open probe circuits - the operator's CNC touch probe), flipping the triggered interpretation; an empty payload is never contact. The overtravel channel is a tripwire: any triggered reading stops the running job, force-closes the machine connection, latches an alarm that blocks every motion tool, and reports to the operator. The latch clears only via clear_overtravel_alarm on the operator's explicit word (refused while the feed still reads triggered) or a restart. New tools (28 total): get_probe_feed_status, connect_probe_feed, disconnect_probe_feed, clear_overtravel_alarm; get_stored_state now carries the feed status.

ONE operator approval covers the whole routine - a new 'procedure' job kind whose confirm page shows the exact motion envelope (validator extents included) and whose server-side runner then steps deterministically against live sensor feedback; the model never chooses a Z during the run. Staged routine (operator-specified): XY to the setter centre at the post-home Z, Z travel to triggerZ + (longest bit - reference bit) + 50mm clearance, 1mm sensor-gated descent to first contact, 1mm retreat until release, 0.1mm approach, 0.3mm backoff, then a confirm pass at 0.1mm per >=2s - retreat and report the measured trigger Z, its delta from expectation, and the derived bit length. Every step verifies settle via the heartbeat and re-checks the overtravel latch; a hard floor (expected trigger Z minus a margin, default 3mm) bounds the descent; any abort retreats to the start height. Requires: homed, idle, toolhead off, probe feed connected (tripwire armed), toolsetter sensor readable and not already triggered. set_/get_tool_setter_config store the operator-stated reference (centre machine XY, trigger Z with a known bit, bit lengths); store_as_reference on a successful run locks the measured Z in. Hardware facts recorded: centre (79, 293), trigger Z 176 with a 75mm endmill. 31 tools total.

Two operator flows, both built on the tool setter (operator-specified): Flow A (MCP-managed): measure the old tool, goto_tool_change_position (operator-set park stored as tool_change_x/y/z in the setter config - this machine: Z at homing height, X at the far end, Y free; one approval, two steps: Z up first, then X/Y), operator swaps by hand, measure the new tool, then apply_tool_length_offset stages a single confirmed G92 Z(current work Z - (new-old)): nothing moves, the work frame shifts so work Z 0 stays on the same physical plane. Measurement history (last/previous, persisted with the config) feeds the delta; differences over 50mm are refused as a mismatched pair. Flow B (touchscreen manual-swap wizard, firmware matches tip positions itself - MCP applies NO offset): run_tool_setter gains stay_at_trigger (measure then HOLD the tip in contact so the operator confirms the matched position on the touchscreen; abort still retreats) and start_from_current (skip travel when the wizard has returned the tool over the setter - verified within 1.5mm of the centre and above the floor before trusting it). Adds .claude/skills/tool-change/SKILL.md with both flows and their failure modes. 33 tools total.

Same staged mechanics as the tool setter: coarse to contact, retreat to release, fine approach, quick lift-and-retest confirm cycles, median + spread reported, retreat to start on completion or abort. survey_bed: one approval drives a serpentine XY grid at the current Z (machine Z >= 250 unless the operator explicitly confirms clearance), capturing a frame per settled waypoint; frames are saved to disk with a machine-position index (bypassing the 12-frame cache) so the whole bed can be reviewed. Aborts on the first capture failure. 35 tools total.

The tip crossed the rotary at physical 128.9mm, struck the stock, and destroyed the probe; the firmware reported ok throughout and the settle verified. The one sensor that knew - the probe itself - was connected and ignored, because only the overtravel channel was a tripwire. Enforcement, mapped to causes: - Safe traverse height (operator law: 'always retreat to top gantry height before x/y moves'): direct XY moves below mcpSafeTraverseZ (default 320) are refused without operator_confirmed_clearance, in move_and_capture/goto_work_origin/visual_servo, the tool setter's travel phase, and survey_bed's staging gate. - Obstacle landmarks: set_landmark gains clearance_z (minimum safe toolhead machine Z over the box); direct XY paths crossing an obstacle's box below it are refused (segment-vs-AABB with 5mm margin). - Crash tripwire: a triggered reading on probe or toolsetter during motion (bracketed in sendGcodeVisible) that no procedure declared as expected contact latches a CRASH alarm - stop job, force-close connection, block all motion - the same machinery as overtravel; clear_overtravel_alarm clears either kind on the operator's word. Procedures declare their expected channels (tool setter: toolsetter +probe with accept_probe_contact; probe_point: probe). - Feed readings now logged server-side (the crash left no trace in the server log of whether the probe fired). - The approved-code page re-shows the exact gcode next to the one-time code (operator request): the last thing seen before handing over the code is what the code will run. - New skill .claude/skills/cnc-probing/SKILL.md and a Motion laws README section carry the incident and the process law that no session may chain motion calls or fabricate clearance heights again.

Requires operator MIN/MAX diameter estimates (start beyond max/2, ABORT at min/2 without contact) and a MEASURED top height. Reports fitted centre, COMBINED diameter (feature + tip, inseparable without one known) and per-azimuth residuals (tip roundness). Repositioning obeys motion law 2: hops only at the safe traverse height. Motion-law hardening from live operator corrections: - Law 2 absolute: ALL XY moves over 1mm at top gantry height - no local hop heights; sub-gantry XY is fine positioning <= 1mm only. - probe_point/probe_vector finish at the traverse height inside the approved envelope (no separate staged lift between probes). - move_z staged gcode self-documents: reason, frame, per-step deltas, and the sensor arrangement (no contact expected; trigger = CRASH). Probe envelopes carry their reason as a comment. - Direct execute path strips comment/blank lines: the controller never replies to a payload led by comments (hung live, job e34b19a913ff); the header stays on the confirm page only. Job-flow fixes found live: - Batch direct jobs can resume past step 1 (consumeToken accepted only 'approved'; a mid-series batch reads 'started' with its token re-armed). - The confirm page re-shows a still-valid code on revisit - a lost tab no longer dead-ends an approval. Docs: work origins do NOT survive machine reboots (re-verify originOffset every session); corrected end-of-job notes.

Staging against that phantom position - with the probe tip inside a hole in the chuck - is how crashes happen. - getPositionSnapshot flags reports older than 10s (period ~1s) with a loud STALE warning; assertFreshHeartbeat refuses procedure starts, move_z staging, job starts and direct moves on stale state. - query_firmware_position errors on an empty M114 reply (the dead-connection signature), and parses a real one as what it is: WORK coordinates in the selected workspace (operator-clarified) - primarily a liveness/frame check - with derived_machine computed via the heartbeat originOffset. - probe_circle gains INSIDE mode (operator-requested, hole checking): the operator positions the tip inside the hole at depth; marches step OUTWARD from that staged origin to the wall, retreat to the origin between azimuths - no hops, no Z motion until the final vertical raise out along the entry path. Result = hole diameter MINUS tip. Bounds still gate every march (abort at max/2 + eccentricity margin). First hardware run: chuck fixed hole, 8 points, fit rms 0.021mm, max residual 0.041mm, centre found 0.27mm from the staged origin. - Recording rule (operator): MACHINE coordinates only - work origins are volatile (a machine reboot mints a new one).

The ProbeFeedService is now transport-generic behind the ProbeTransport contract (probeTransport.ts): readings, polarity, the safety latch and reconnect backoff stay in the service; MQTT moved unchanged into MqttProbeTransport. The GPIO backend (gpioFeed.ts) spawns a python -c Blinka monitor that polls the pins (default 10 ms) and streams JSON lines - readings on change plus a 1 s heartbeat that is both liveness watchdog (silent 5 s -> reconnect) and freshness refresh. Pins configure as name:pull ("D2:up"); polarity uses the shared inverted mechanism. Verified on a real KB2040_U2IF (Ubuntu 24.04 box, probe A0 inverted, toolsetter D2, overtravel D3; bump test passed) and with a stubbed Blinka. gpio_bumptest.py verifies wiring and polarity by hand; requirements.txt pins Blinka + hidapi. Settings -> MCP Server exposes the transport choice (Auto/MQTT/GPIO), pins with inversion, python, poll interval and Blinka environment, flagging env overrides. Workspace -> Connection shows Probe / Tool Setter / Setter Overtravel pills (yellow unknown, green idle, red contact) driven by GET /api/mcp + mcp:activity, with an ALARM marker and an operator Clear alarm button (POST /api/mcp/clear-alarm -> clearTrip). Safety policy (operator, 2026-09-04): the overtravel tripwire latches only while a sensor-gated procedure or MCP motion is in flight (procedureArmed); a hand bump test with the machine idle is reported, not latched. The crash guard is now armed inside moveMachineSettled (every procedure move), not only move_and_capture. README, skills and install steps updated.

Devices are enumerated from /sys/class/video4linux (index-0 capture nodes only) and reported by udev's stable /dev/v4l/by-id path, because /dev/videoN renumbers when cameras come and go. The sticky last-good logic is untouched; a vanished device is still an error, never a substitution. Ubuntu 23.10+ restricts unprivileged user namespaces; without an AppArmor profile granting userns the Chromium sandbox aborts and Luban dies on launch with "Trace/breakpoint trap". The deb/rpm post-install (build/linux-after-install.sh, replacing electron-builder's template while keeping its symlink / SUID sandbox / desktop-db duties) writes /etc/apparmor.d/snapmaker-luban and reloads it; post-remove deletes it. Mac fork builds: unset repo secrets arrive as EMPTY env vars and an empty-but-set CSC_LINK made electron-builder import a certificate from "" (" not a file"). electron-builder.sh unsets empty CSC_* (before set -x) and disables keychain auto-discovery; the afterSign hook ad-hoc signs so the x64 + arm64 dmg/zip launch on Apple Silicon. All three platforms build green via workflow_dispatch. cnc-visual-alignment notes the per-platform camera device entries.

The private configstore key mcpInstalledModules is removed; the profile also falls back to the selected machine when none is connected and reports machineSettings + installedModulesSource. The MCP README absorbs everything that previously lived only in the assistant's memory files, so no new user (or agent) depends on them: the Ubuntu box deployment notes (KB2040/U2IF wiring and polarity, the udev rule needing SUBSYSTEM=="usb" because pip hidapi uses libusb, camera identification and by-id pinning, AppArmor, launching into an RDP session, where operator state lives and how to migrate it), the remaining hardware measurements (rotary stock, chuck fixed hole, post+hole = 10.41), standing operator rules not enforced in code, the current PR stack (#70-#73), Claude Code's MCP schema cache, startup facts, assistant tooling gotchas, and the open threads (results on the job record, traverse_xy, console ANSI leak, install size, GPIO-sized delays). The main Luban README gains a single line linking the MCP server with a health and safety warning: do not use it unless you accept software- commanded motion, never leave the CNC unattended or approach it while running, wear appropriate PPE.

A disabled sensor's channel is unbound on every transport - no topic or pin subscribed, no readings, no Workspace pill - and every procedure that needs it refuses through assertChannelReady with a message naming the setting; the feed is not even connected when only disabled sensors are configured. The operator will often run without the USB sensor bridge plugged in. Blinka's "BLINKA_U2IF ... no compatible device found" (and hid "open failed") is now classified as `bridge: not detected`; the service still retries with backoff but logs each distinct error once and thins the reconnect log after the third attempt, and get_probe_feed_status reports `unavailable: true` so the UI shows unknown pills instead of an error storm. mcpAllowLan / LUBAN_MCP_ALLOW_LAN (default off) binds the server on every interface but accepts only clients - and browser origins - on this machine's own IPv4 subnets (IPv4-mapped IPv6 unwrapped, other IPv6 refused); confirm-page links then use the LAN address, preferring real subnets over /32 VPN interfaces. There is no authentication, so the pane shows a red warning and lists the LAN URLs. Verified the subnet gate against this machine's real interfaces (same subnet incl. ::ffff: form allowed; other subnets, public, IPv6, garbage refused). README config table, architecture note and skills updated.

Every job now keeps an event log - state changes, the runner's phase announcements and probe-feed readings/alarms broadcast while it is the active job, gcode sent/replies, file-job progress every 5 % - and the procedure outcome is stored as job.result. get_gcode_job_status returns events (from since_event), result, terminal, and long-polls with wait_ms (up to 120 s), returning as soon as the state turns terminal or new events arrive, so one call replaces a polling loop. survey_bed's grid was a fixed pitch plus a stub at the far edge: with pitch 80 the rows ran 10, 90, 170, 250, 330 and then 340 - 80 mm jumps and a 10 mm tail, on both axes (surveys 25c4f87a / b123d156). pitch_mm is now a MAXIMUM: each axis span is divided into equal steps no larger than it (min 20), so rows and columns are uniform and both edges are covered; the response reports the effective step per axis and the coordinates. cnc-probing skill: wait on jobs with get_gcode_job_status wait_ms, never the server log.

The SSTP status poll rebuilds originOffset from offsetX/Y/Z on every beat, and a beat inside the move's G53...G54 window carries none; getPositionSnapshot fell through `|| 0` and silently reframed machine coordinates as work coordinates. A missing offset now reuses the last complete offset seen on the connection (originOffsetSource: cached, with a warning; assumed-zero only before any offset was ever reported, loudly), and the sequence runner's re-check re-reads once after a heartbeat period before aborting, reporting work/offset/source when it does. start_gcode_job on a procedure ran the whole runner inside the request, so tool setter and probe circuits (minutes) exceeded MCP client timeouts - twice now - and a client giving up could not see the result. The runner is detached: the outcome always lands on the job record; the call waits wait_ms (default 25 s, max 120 s) and returns the result if it arrived, otherwise a running status to long-poll with get_gcode_job_status.

Floor without contact = station recorded no_contact, reference unchanged, scan continues; the FIRST station finding nothing aborts. - start_z_machine REQUIRED (measured or operator-stated): the approach to station 1 is a full law-2 move - raise to the traverse height, hop at gantry height, guarded 1 mm descent (contact = CRASH). Caps are enforced by refusal at staging (surfaceScan.resolveEnvelope, assertHopsWithin); mechanics at runtime (probeSurface.ts): hops through moveMachineSettled with clearExpectedContact() in <= 10 mm sensor-checked segments so a touch during a hop latches CRASH, marches with setExpectedContact(['probe']), staged-position and per-march position re-check with one re-read after 1.2 s, abort-raise to the traverse height, phases via mcpBroadcast, structured result on job.result. surfaceScan.ts is import-free so it compiles alone; 23 unit tests cover station generation (path, serpentine grid incl. row turns), the 60 mm hop refusal, floor computation, line/plane fits with residuals, the Z matrix and the ASCII renderings.

Once 1000 entries accumulated, each push rotated the start index, so slot 0 became the oldest console line and the input element started mirroring console history - raw ANSI colour codes included (the ESC byte is unprintable in an , leaving e.g. "[35m14:52:00.108 [mcp:circle:confirm:az135] > G53[39m"). Verbose MCP probing floods the buffer past 1000 lines quickly, which is why it surfaced mid-procedure. Reproduced against the real CircularArray: the draft survives to entry 1000; entry 1001 replaces it with "line 1". The mcp:gcode broadcast itself was never coloured - the server sends raw gcode; cli-color magenta is applied in the Console widget for xterm rendering, where it belongs. Server-side log colouring untouched. Fix: keep the draft out of the circular buffer. Terminal.jsx holds it in a module-level inputDraft (same singleton pattern as its term / fitAddon, so it still survives page-switch remounts) and the input is now fully controlled; arrow-key recall goes through React state instead of writing event.target.value directly. terminalHistory is purely console lines: clear() no longer seeds a '' sentinel, the replay loops start at index 0 (they previously skipped slot 0 and, after rotation, silently dropped a real line), and a hasGreeted module flag keeps the help text from re-printing after clear + page switch.

Both hop segments had been echoed by the controller at their targets, but the re-check judged two heartbeats: one lagging (previous segment's position) and one carrying machine-frame coordinates - the HTTP channel sends G90 / G53; / G1 / G54; as four requests and a status poll inside that window reports the G53 frame, with the offset still populated, MISSING, or read as (0, 0, 0). The WiFi heartbeat is a 2 s poll, not ~1 s. - positionOfRecord.ts: pure judgement helpers. matchFrame accepts a report in either frame; judgeRecheck passes on a matching report or on the engine's record while the report predates it, treats a report still showing the pre-move position as stale (job de932e286afd: a 4 mm hop's echo verified X174, the next beat - stamped 750 ms later - still read X178 and, read twice with 1 ms of clock jitter, counted as two agreeing beats), and aborts only when two beats >= 1 s apart agree the machine is elsewhere; judgeOffsetReport treats a zero offset that contradicts the cached non-zero one as a transient until it persists for 3 QUIET beats (none while direct gcode is in flight) - job 70b2b8c675a6: all 84 settle-waits carried offset 0,0,0 (the stall root cause); job 42df7b9351b7: the same beat read Z320 as Z-8 before a descent. The engine also keeps its own trusted offset (the one that last proved an arrival) and judges echoes with it first. Verified on the 133-station band-1 grid: settle-wait 0, zeroOffsetStreak 0, median station 13.5 s. - probing.ts: every verified arrival becomes the position of record; echo and settle checks are frame-aware; "stable" means two DISTINCT beats; operator rule: a <= 1 mm move with no contradicting echo is taken as arrived after a 400 ms grace when the heartbeat lags (position-estimated event). Shared expectMachinePosition replaces the per-runner re-read-once checks; knownMachinePosition() (record first) drives runner descents, which abort if the toolhead is already below the target; move_z waits accept either frame too. - Operator law (2026-09-05): every procedure descent toward the work runs in <= 5 mm segments (descendInSegments) with a lenient settle that never waits on the heartbeat - a single long G1 cannot be stopped once sent. Contact detection during descents is asynchronous: the probe feed's crash guard latches CRASH the instant an unexpected channel fires in flight and the next segment is refused; a serial senseAfter check is opt-in (serialCheck) for manoeuvres that need a synchronous verdict. Surface scans, probe_sequence, probe_circle and the tool setter's travel (which clears its expected contacts for the descent) all use it. - Slow zone for surface scans (jobs d8f6ec1b5c11 / cdbc29371b97): a coarse step is executed whole before the runner sees the probe, so the coarse ladder pressed the probe past contact by up to a full step. From station 2 coarse steps stop slow_zone_mm (default 1) above the previous contact and fine steps take over to slow_zone + 2 x coarse below it; station 1 caps coarse at 1 mm unless expected_z_machine (a measured neighbour) is given. coarse_step_mm is capped at 1 mm in EVERY probing procedure (operator: never 2). Confirm pages print the zone; results carry approach and worstPressMm. sensor_delay_ms floor 30 (was 100). - Approval hand-off (operator request): start_gcode_job with wait_for_approval_ms (<= 120 s) stays open until the operator clicks approve on the confirm page and then starts the job with no code to copy (approved: false, timed_out: true when they have not clicked yet; call again). The click in the browser remains the only authority. mcpApprovalHandoff agent|code (Settings -> MCP Server -> Job approval, LUBAN_MCP_APPROVAL_HANDOFF) restores the relayed-code scheme. - diagnostics.ts: event-loop stall ticker, heartbeat cadence / gaps / frame flips / zero-offset beats, gcode exec/idle timing with a step trace and slow_step events, sensor pipe latency (GPIO monitor stamps ts), sense_overrun and settle-wait/settle-done events; get_mcp_diagnostics tool (incl. originOffset cache/streak/trusted) and /api/mcp field. - Buffer sizes are settings: mcpJobEventLimit (default 2000, 400-100000) and mcpDiagnosticsRecentLimit (default 40, 10-10000), env overrides, editable in Settings -> MCP Server -> Diagnostic buffers; job events page by seq so since_event / next_event_index survive trimming. - README + skills (cnc-probing, tool-change, cnc-visual-alignment): heartbeat frames, position-of-record rules, segmented descents, coarse press / slow zone / 1 mm cap, approval hand-off, diagnostics, buffers and the event-log budget for large grids.

New pure module machinePosition.ts judges each distinct heartbeat: a controller echo (position of record) outranks it; a beat whose derived machine value is more than 50 mm outside the travel, or whose raw fields jumped by exactly the offset (frame flip), or that arrived before any offset was reported, is REJECTED - the last accepted position is held with `reliability: awaiting-resync` until a coherent beat rectifies it (operator law 2026-09-14: such a reading is a mistake, never a position; ignore it, do not reinterpret it). Nothing is assumed. getPositionSnapshot now returns the judged `machine` plus `reliability`, `frame`, `reasons` and the rejected beat's `derived` value for diagnostics. assertFreshHeartbeat - already in front of every procedure start, direct move, job start and Z staging - refuses on awaiting-resync/stale, so a Z 555 artefact can no longer pass the traverse-height guard or a landmark clearance check; survey_bed and the tool-setter tools gate explicitly. The state (cached offset, zero-streak, previous raw, last accepted, trusted offset, echo record) is consolidated and forgotten on every (re)connection, because work origins die on a machine reboot. The gcode sequence counter moves into positionOfRecord.ts so tools/machine.ts can read the echo record without importing the channel code. The Workspace console no longer prints its own unguarded subtraction (the ">500" lines): Marlin:state shows the raw report, and a new mcp:position event carries the judged machine position and its reliability once per beat (UI-only broadcast, not recorded on the job). get_mcp_diagnostics reports rejected beats by reason, resyncs and disconnects. 13 unit tests cover the judge, including the recorded incidents (Z 555.7 / Z 656 artefacts, the zero-offset streak, the return from a G53 window).

The crossing-landmark exemption for segments at or above the traverse height is removed from checkMotion: it existed because the rotary-axis landmark's clearance (328) sat above the old traverse height, and it let a traverse cross the rotary box - tailstock included, height unmeasured - with 8 mm of unverified headroom. At 328 a hop passes every stored clearance on its own merits; a hop below 328 (surface scan, stepped link) is checked like any low segment; marches stay exempt (they stop on contact); volumes refuse at any Z below their clearance. get_stored_state.limits reports safeTraverseZMm.

The new traverse_xy tool is the transport twin of move_z: an absolute XY target or an ordered series (max 20) at the traverse height, ONE operator approval on the confirm page, one start_gcode_job call per leg on the direct path so the position persists. Refused unless the toolhead is already at or above mcpSafeTraverseZ (328) - raise with move_z first; there is deliberately no override. Every leg is checked against the stored landmarks (checkMotion) and every target against the travel; Z is never written; default frame MACHINE with G53 declared on every step (work-frame steps declare G54). The planner is a pure module (traversePlan.ts, 10 unit tests, 44 total) and the confirm header states frame, current position, Z-unchanged, every leg with its machine coordinates and distance, total travel and the sensor note.

The runner's abort path tested `err instanceof ProcedureAbort`, which is false for an Error subclass once the prototype chain is lost in a down-levelled build, so the partial result it had built was never attached. ProcedureAbort / ProcedureStopped now live in a pure module with a marker property, an explicit prototype and isProcedureAbort / isProcedureStopped helpers, and every runner tests the marker. start_gcode_job stores the partial result on any abort, with the ending beside it. Every job now carries a structured `ending` (kind, reason, when, how many stations/ops were measured): completed, stopped-by-agent, stopped-by-operator, withdrawn, rejected-by-operator, crash-alarm, overtravel-alarm, unexpected-contact, controller-rejected, timeout, operation-failure, machine-stopped, completion-unverified - classified in the pure jobEnding.ts. File jobs log each pause (door interlock or operator pause) and say so in their ending; describe(), get_gcode_job_status and the stop_gcode_job note all report it. 6 new tests (51 total), including the lost-prototype case.

The critiques converged; this applies them: cnc-motion-rules: checklist first with "ask once" and a transit fast path; law 1 resolved against law 6 (a named procedure authorises STAGING, the page is the decision point, a program is one decision point); below-328 transits ask for the Z lift; chat-stated landmarks and clearance == 328; law 6 names every motion tool, wait_for_approval_ms, confirm-URL delivery and the "no confirmations" answer; law 7 allows file jobs for programs; work-frame case first in the handshake; operator-stated probe length = which probe, not the value; resync is passive with re-read thresholds; new S7 "Running a program someone else generated" and S8 canonical calls with the real argument schemas (traverse_xy, move_z, submit/start/status, run_tool_setter, the two-op find-then-scan probe_program and the reference grammar); incidents moved to an appendix. cnc-probing: 407 -> 191 lines. Laws are a pointer; leads with find-then- scan; unknown-Z route and its cost; measuring inside an unmeasured region (retiring a keep-out); op-selection table (probe_circle is vertical-axis only); spacing fencepost; hop_mode by spacing x slope; event budget at the point of decision; reading a profile (symmetry centre, not highestAt); bit_length_mm is a protrusion. CAM probing moved to references/, the bed survey moved to cnc-visual-alignment, which gains the viewing-pose arithmetic. TOOLS.md: `home` no longer claims to clear stale position state; argument lists on the job and motion tools. evals/evals.json (8 prompts, assertions) and evals/REVIEW-2026-09-14.md record the method, numbers, findings and the eval-set critique; run outputs live under .claude/skill-evals/ (ignored).

One approval, no questions. ## 1. The seven motion laws 1. **One motion per instruction, and no inferred approvals.** When the operator enumerates steps, execute exactly the step they name and stop. NEVER chain motion calls in a single - command (`&&`, one script, one turn) — each motion needs a decision point in front of it. - The 2026-09-01 crash happened because step 2 fired 117 ms after step 1 succeeded, with no - chance to intervene. A motion is authorised ONLY by an explicit imperative in the operator's - latest message ("home it", "go", "run the probe"). A motion mentioned in passing — "take a - photo before homing", "then we'll traverse", an approved plan that lists it — is context, - not a command: announce the next motion and WAIT for the word (violated 2026-09-02: homed - off the back of "before homing"). + command (`&&`, one script, one turn) — each motion needs a decision point in front of it + (appendix A, incident 1). A motion mentioned in passing — "take a photo before homing", + "then we'll traverse", a plan they approved — is context, not a command: announce it and + WAIT for the word. **Resolution with law 6**: a request that names a procedure ("scan the + tailstock", "probe along X from 164 to 176") authorises STAGING that procedure; the confirm + page is its decision point. A staged program or procedure is ONE decision point for every + move inside its approved envelope — that is the efficient lawful form, not a violation. 2. **X/Y traverses happen at top gantry height — ALL of them.** Any XY move over 1 mm is - planned at the traverse height (`mcpSafeTraverseZ`, default **machine Z328** = home Z), - with no exceptions: not between probe points, not "local hops" above a measured feature - top, not at any other "measured safe" height (operator, 2026-09-02: "x/y motion over 1mm is - never below gantry height"). Retreat Z FIRST, traverse, then descend at the destination. - The only sub-gantry XY motion is fine positioning of ≤ 1 mm (touch-test nudges, probe march - steps) and the in-procedure envelopes in §4, which the operator approves on the confirm - page as part of that one tool call — the NEXT motion starts from a full retreat again. - Enforced: direct XY moves below `mcpSafeTraverseZ` are refused without - `operator_confirmed_clearance`, which only the operator's explicit words authorise and which - is for emergencies, never for planning around this law. + planned at the traverse height (`mcpSafeTraverseZ`, default **machine Z328** = home Z; a + head reading 327.999 is at it).

Visual inference from camera frames is for FINDING things, not for clearing them — - the crash analysis misread the same stock's orientation twice from photos. If a height is - unknown, ask, or measure from a proven-safe height with `probe_point`. -4. **Landmarks are obstacles.** Give bed fixtures a `clearance_z` in `set_landmark`.

Hand-derived "machine" values of Z555 and Z656, and a verified Z320 read -as Z−8, all came from doing the subtraction on one such beat. The server now judges; you read. +**Nothing you do performs the resync.** The server clears `awaiting-resync` when a coherent +beat arrives (normally the next one, 2 s). Homing does not clear it, reconnecting does not +clear it, re-reading only lets you see that it cleared.

If your MCP client times out anyway, the result is still on the record. -`next_event_index` is a sequence number, not an array index: the log keeps 2000 events and -paging stays valid when it trims. - -**Stopping a procedure.** `stop_gcode_job {job_id}` on a running procedure (probe_*, -probe_program, tool setter, survey) is a cooperative stop: the runner finishes the step in -flight (<= 1 mm or one sensor window), raises to the traverse height and ends the job in -state `stopped` with everything measured so far in `result` (stations, contacts, -completed ops, `derived`). The call waits up to `wait_ms` (default 20 s) and answers -`{ok: true, stopped | stopping}`; if `stopping`, long-poll the status.

A procedure that has not -started yet is withdrawn by the same call. - -When a procedure is slow or aborts, the evidence is already in its events - do not grep -server logs. `gcode` events carry `execMs` (send to controller reply) and `idleMs` (previous -reply to this send; engine + sensor window only, so > 750 ms inside a job also raises a -`slow_step` event). `event_loop_stall`, `heartbeat_gap`, `heartbeat_frame_flip`, -`sense_overrun` and `position-estimated` events name the server-side cause when there is -one; `get_mcp_diagnostics` has the totals. The machine heartbeat is a 2 s poll: a -`position-recheck` note saying the record or a machine-frame (G53 window) report was used -is normal, not a fault - the runner verified every move against the controller's echo. -Likewise a `get_position` warning that a zero work-origin offset was set aside (a -G53-window beat reports offsets as 0,0,0 with machine coordinates in `pos`) is the server -protecting you: machine coordinates stay right, `originOffsetSource` reads `cached`. Only a -zero offset that persists for 3 beats is believed. If a scan aborts saying the toolhead is -BELOW the descent target, do not re-stage from a lower `start_z_machine` - verify the -position with `query_firmware_position` first; the check exists because one bad beat once -read Z320 as Z-8. - -`survey_bed`'s `pitch_mm` is a MAXIMUM: each axis is divided evenly into steps no larger -than it (min 20), so rows and columns are uniform and both edges are covered — no more 80 mm -jumps followed by a 10 mm stub. Pick the pitch from what one frame covers. - -## Circle probing - -`probe_circle` measures a roughly-round vertical feature (post, boss, pin): -N radial marches from evenly spaced azimuths, one staged envelope, then a -least-squares circle fit. It REQUIRES the operator's min/max diameter -estimates (marches start beyond max/2 and abort at min/2 without contact) -and a MEASURED top height. Physics: every contact adds the tip's effective -radius, so the fit yields the COMBINED diameter — feature and tip are -inseparable unless one is known. Direction-dependent residuals expose an -out-of-round tip (the post-unbending health check). Repositioning between -points obeys law 2 in full: lift to the safe traverse height, hop, descend; -a probe touch during a hop or descent latches the CRASH alarm. +Both procedures measure a TOP surface with many −Z marches under ONE approval; every number is +machine coordinates and every contact Z is TOOLHEAD Z. -## Surface flatness and height maps +- `probe_surface_path` — N stations along a line: `start_x/start_y` + `end_x/end_y` (or + `dx/dy` + `length_mm`); `stations` (2–400; above 60 the confirm page warns about duration and + event budget) or `spacing_mm` (a MAXIMUM; stations = `floor(length / spacing) + 1`, both + ends included — 164→176 at 0.2 is 61 stations, 164.1→175.9 is 60).

The runner reaches station 1 law-2 style (raise, hop at 328, segmented guarded +descent), then works the envelope. -Two staged procedures measure a TOP surface with many −Z marches under ONE -operator approval; every commanded move is enumerated on the confirm page, -all numbers are machine coordinates, and every contact Z is TOOLHEAD Z (the -surface is that minus the probe length). - -- `probe_surface_path` — N stations along a straight line (`start_x/start_y` - plus `end_x/end_y` or `dx/dy` + `length_mm`; sampled by `stations` count or a - MAXIMUM `spacing_mm`). Use it for "is this stock level along Y", "how much - does the board rise toward the free end", a rotary-mounted flat. Result: - per-station XYZ (or `no_contact`), Z min/max/range, best-fit line slope (mm - per 100 mm and degrees, rise over the length), flatness = residual - peak-to-valley, a text profile. -- `probe_surface_grid` — a serpentine grid over a region (`x_min..y_max` or - `center_x/center_y` + `size_x_mm[/size_y_mm]`; sampled by a MAXIMUM `pitch_mm` - or `x_count/y_count`, max 400 stations).

Result: - `zMatrix` (rows = ys ascending, cols = xs ascending, null = no contact), - best-fit plane (tilt X/Y) with per-point residuals and flatness, and a text - `heightMap` printed with +Y at the top like the bed seen from above. - -`start_z_machine` is REQUIRED for both: the toolhead machine Z at which the -first march starts with the tip just above the surface — measured (an earlier -`probe_point -Z`, a previous scan) or operator-stated, never inferred from a -photo (law 3). The runner reaches it law-2 style: raise to the traverse height, -hop at gantry height to station 1, then descend in ≤ 5 mm segments to 20 mm -above `start_z_machine` under the asynchronous crash guard (a probe touch latches -CRASH and the next segment is refused), then a guarded 1 mm descent with a serial -sensor check after each step. Every procedure descent is segmented like this -(operator law: a single long move toward the work cannot be stopped once sent), -and the segments do not wait on the heartbeat - expect `position-estimated` notes. - -**The envelope (operator law, 2026-09-05)** — the ONLY exception to motion law -2, valid inside these two procedures only, between consecutive stations only. -The operator's words: "no more than 20mm z safe delta from the top (within a -horizontal change of 60mm)". - -| Parameter | Default | Hard limit | Meaning | +**Envelope (operator law, 2026-09-05)** — the one exception to law 2, between consecutive +stations only.

Also bounded by `floor_z_machine` (default `start_z_machine − max_drop_mm`), the deepest Z the scan can ever command — shown on the confirm page. | - -Reaching the floor without contact records the station `no_contact` and the -scan CONTINUES with the reference height unchanged (a pocket, a hole, an edge -overshoot); the first station finding nothing aborts. Hops run in ≤ 10 mm -sensor-checked segments expecting NO contact — a touch during a hop means the -surface rose more than `z_safe_delta_mm` and latches the CRASH alarm (law 5). -Completion and abort both raise to the traverse height. Never ask for the caps -to be widened and never approximate a scan with `probe_sequence` hops at a -"measured safe" height — that is exactly what law 2 forbids. - -**Coarse press.** `coarse_step_mm` is also the worst-case press into the probe: -the controller finishes a step before the runner sees the sensor. From station 2 -the runner uses the previous contact as the expected height and switches to fine -steps `slow_zone_mm` (default 1) above it — press one fine step. Station 1 has no -neighbour, so its coarse step is capped at 1 mm unless you pass -`expected_z_machine` (a MEASURED neighbouring contact — a `probe_point -Z`, a -`probe_sequence` centre, an earlier scan; never a guess, law 3).

Bounds are required (law 3): -the confirm page shows them, and the runner refuses the op outside them, stops the -program raised and keeps earlier results under `result.ops`. Order ops so every -reference points backwards; `on_fail: "skip"` lets an overtravel-type op fail -without ending the program. A four-face survey is `rotate_b 90 → centre sequence → -N-S path → W-E path → sides sequence → rotate_b 180 → …`; budget the event log -(≈ 100 + stations × 120 per scan op) before staging and use -`wait_for_approval_ms` to start. Staging REFUSES a program whose estimate exceeds the -job event limit and tells you the number to ask the operator for. - -**New stock, nothing known but the jig.** Geometry is NEVER a prerequisite: a program -that references only its own earlier ops (any B0-only, stationary or off-rotary survey) -needs nothing stored, so stage it. Only a reference to `axis.*` needs the rotary axis -and probe length; check `get_stored_state → geometry`, and if they are unset, MEASURE -them and store them yourself with `set_probe_geometry` (axis Z = mean of an -opposite-face pair minus the probe length, axis X = mid of a side pair, probe length -from `run_tool_setter accept_probe_contact`) - or write the program without `axis.*`. -Never ask the operator to type numbers into a settings pane, and never type them into -your program as constants. Stock size is a property of the stock, not the jig: pass the -largest reach of THIS stock as `swept_radius_mm` on `rotate_b` if you want the -tip-outside-the-cylinder check. Then: - -- **Find the top** without knowing the height: a `sequence` whose `descend` is - `{"from": "axis.z_contact", "plus": , "between": [...]}` - and whose probe is `dz: -1, max_travel_mm: ` (segmented descent, 1 mm - coarse in the last band). Without `axis`, descend to an operator-stated Z instead. -- **Derive, don't guess**: `{"mid": ["s0.west.x", "s0.east.x"], "between": [...]}` is the - stock centre; `{"diff": ["s0.east.x", "s0.west.x"], "scale": 0.5, "plus": - "axis.z_contact", "between": [...]}` is the B90 face height (axis + half-width); - `{"min"|"max": [...]}` over several paths. References may sit anywhere in an op's - arguments (`steps[].z`, `start_x`, `expected_profile.circle.center_x`). Name your - probes `top`, `west*`, `east*`, `end*` and the result's `derived` section (thickness - per face pair, centring, width with tip, centre X, yaw, end slope) is computed for - you - it is planning inference, never a clearance. -- **Keep-out for this clamping**: pass `keep_out: [{"name": "chuck jaws", "machine": - {"x0", "y0", "x1", "y1"}, "clearance_z"}]` (toolhead Z) - a VOLUME nothing enters, not - even a descent column. Stored landmarks are CROSSING obstacles: they forbid traversing - into or out of their box low, and a hop, column or march wholly inside one (probing - the stock inside the rotary-axis landmark) is allowed - the operator approves it on - the page. So never ask to delete or shrink the rotary landmark to make a scan pass; if - a check names it, the plan really does enter or leave the rotary region low. Both are - checked at staging AND when references resolve; a hit names the step. Jaws reach - ~Y269 on this jig (measured 2026-09-02); the tailstock bracket stands above the stock - below ~Y110 - use those as `keep_out` volumes, with the operator's confirmation. -- **Cylinders**: `surface_path` with `expected_profile: {"circle": {"center_x": {"from": - "axis.x", ...}, "center_z_contact": {"from": "axis.z_contact", ...}, "radius": }}` - each station's slow zone and drop band follow the circle; stations more than - 0.7 R off the axis are refused. Locate the crown with `summary.highestAt.x`. -- **Repeat per rotation**: `{"id": "faces", "kind": "group", "for_b": [0, 90, 180, 270], - "ops": [...]}` runs the inner ops once per angle after a `rotate_b`; write `${b}` in - ids/names/paths (or leave ids plain and they get `_b`). - -- **Side marches on stock of estimated size**: start each march OUTSIDE the largest - size the stock could be, set `max_travel_mm` to cover the whole uncertainty (the - travel is approved, so a long limit costs time, not safety), and put the first side - probe at mid-length, never near a corner. A march that reaches its limit records - `status: "no_contact"` and the sequence CONTINUES (`on_miss` default) - a miss is the - measurement "nothing within N mm". Only pass `on_miss: "abort"` when a later step is - unsafe without that contact. A reference to a missed probe refuses its op instead. - -**Block on the bed or in the chuck: `probe_stock_outline` (centre from an estimate).** -Give it the estimated centre and size, the operator's `start_z_machine` / -`floor_z_machine`, and it finds the top at `top_points` (default 3; the highest wins, a -sample > `hole_tolerance_mm` lower is a hole and ignored - so a first probe in a drilled -hole cannot define the surface), then marches the sides from `overextend_mm` outside the -estimate at `top - side_depth_mm`, `points_per_side` per side, skipping along each face at -`side_standoff_mm` off the last contact (a projection bumps the probe outward, never -aborts), and returns `centerMachine`, `centerWork`, `sizeMm` (centre-to-centre), -`sizePhysicalMm` (MINUS the tip diameter - external faces lie one tip radius inside their -contacts; the centre needs no correction), `yawDeg`. Use it instead of hand-built -sequences whenever the job is "where is this block and how big is it". Defaults are -deliberately generous: `points_per_side` 3 (midpoint first), `side_max_travel_mm` 25, -`overextend_mm` 5, `side_depth_mm` 2. Do NOT shorten the travel to save time: the first -outline on the box marched 11 mm and missed a face 13.6 mm away because the centre estimate -was 3.85 mm off - travel must cover overextend + width uncertainty + centre uncertainty + -margin, and a march that finds nothing is only lost time. For top scans over stock that may -be narrow or offset from the estimate, keep `spacing_mm` at 5 or less. Also an op kind -`stock_outline` in `probe_program`. For surface scans over uneven or holed stock use -`hop_mode: "stepped"` with `hop_lift_mm` (contact lifts and continues) instead of a big -`z_safe_delta_mm`. - -**A probing program from CAM (Fusion 360 / FreeCAD / Grbl post): `run_probing_gcode`.** -Pass the program text as `gcode` with a `reason`; it is translated, never sent raw: -each `G38.2`/`G38.3` becomes a sensor-gated march to its target (the travel limit, so -post the cycles with GENEROUS travel - the same lesson as the outline: a short cycle -silently misses), `G38.4`/`G38.5` a probe-away until release, links follow law 2 -(`link_mode` "raise" default; "stepped" for touch-probing links at the programmed -height). Feeds in the file are ignored; M3/M4, M0/M1, M6, G28, G92, arcs and `#` -macros are refused with the line number - fix the post, do not strip lines by hand -without telling the operator. Coordinates are the CAM WCS (work frame) unless `frame: -"machine"`; the work origin must be live on the heartbeat. Put `(PROBE id=.. name=.. -nominal=x,y,z normal=i,j,k tol=u,l)` before a cycle so the report carries nominals and -tolerance verdicts. Read `reportText` (default `fusion` = Fusion "inspection results" -G800/G801 text the CAM imports; `csv`, `grbl`, `json`) or call `get_inspection_report` -for another format; the file path under `mcp-inspection/` is in `files`. Use -`report_format: "renishaw"` for Probe WCS / Probe Geometry features (Fusion imports the -Renishaw print-out for those) - it needs `group=`/`role=` (`x_minus`, `x_plus`, `y_minus`, -`y_plus`) and `feature=`/`nominal_size=`/`nominal_center=`/`tol_size=`/`tol_pos=` in the -`(PROBE …)` comments; `fusion` is for Inspect Surface points. The repo ships a Fusion post -that writes all of this (`docs/post/snapmaker-probing.cps`, unverified in Fusion) and a -firmware note: the Snapmaker controller compiles G38 in but on the 3DP probe input, so the -MCP always translates - never expect a raw G38 to touch the CNC probe. - -**Landmarks vs the traverse height.** The traverse height is machine Z328 (home) and every -stored landmark clearance is at or below it, so a hop at the traverse height passes the -crossing check on its own merits — there is no exemption. A hop BELOW 328 (a surface-scan -hop, a stepped link) is checked against crossing landmarks like any low segment; marches are -exempt because they stop on contact. A refusal naming a landmark therefore means a low hop or -a descent column enters or leaves its box - fix the plan, do not touch the landmark. The -tailstock inside the `rotary-axis` box is UNMEASURED: treat Y < 110 there as a `keep_out` -volume until it has been probed. - -Hardware test order for a new program: B0 half without rotations first, then one -rotation, then the whole program - and compare `derived` with the operator's calipers. - -**Speed.** Read `result.timing` (or `get_job_timing`) after a scan instead of mining -events: per command kind it gives count, feeds, distance, controller time vs motion -time vs overhead, idle and sensor windows, plus per-station wall time. The coarse walk -down from the hop height is the biggest cost (~19 of 30 commands per station at -`z_safe_delta_mm` 20), so on stock known to vary < 5 mm between stations use -`z_safe_delta_mm: 5`, `confirm_passes: 2` and `sensor_delay_ms: 30` on GPIO (an -11-station path ~400 s → ~170 s). Never raise the coarse feed yourself: impact speed is -the operator's call. - -**Event-log budget — check it BEFORE staging a large scan.** The job keeps at most -`mcpJobEventLimit` events (default 2000; `get_mcp_diagnostics` → `buffers` and the -Settings pane show the live value). Beyond that the log keeps its first 20 events -and the newest tail — `eventsTotal` > `eventCount` on the job tells you it trimmed. -The procedure `result` (stations, fit, height map) is stored separately and is -never trimmed; only the step-by-step evidence is. Measured cost (8-station path, -`z_safe_delta_mm` 20, coarse 1, fine 0.1, 3 confirm passes: 763 events): - -| Item | Events | -|---|---| -| Fixed: approval, raise, traverse, 20-step guarded descent, final raise | ≈ 100 | -| Per station (coarse ladder over the 20 mm retract ≈ 19 steps, ≈ 10 fine, 3 confirm cycles, hop segments, readings, diagnostics) | ≈ 90–120 | -| Same with `z_safe_delta_mm` 5 on a known-flat surface (4 coarse steps) | ≈ 60 | - -So `events ≈ 100 + stations × 110` (use 120 to be safe): the default 2000 covers -about 15 stations; a 5 × 5 grid needs ~3000, a 10 × 10 grid ~12 000, the 400-station -maximum ~48 000.

PR #90 fixed the ABORT path; this makes the SUCCESS path end the same way: a Z-only G53 raise straight up to mcpSafeTraverseZ, nothing sent if the head is already there (float tolerance), never back to the start height. stay_at_trigger (touchscreen manual-swap wizard) is unchanged: the tip is held in contact, no retreat at all. - probing.ts: factor the shared `raiseToTop` (trip = no motion, optional hold-if-triggered, skip at the top, else one Z-only move; returns the outcome and final Z); `abortRaiseToTop` is now a wrapper that uses the abort-* phase names and clears expected contact before the raise, exactly as before. The success-path lift keeps the setter channels expected (it starts in contact), as the old retreat did. - traversePlan.ts: `planAbortRaise` -> `planRaiseToTop` (same decision, both paths); new pure `planToolSetterEnd` (hold / raise / skip) drives the confirm-page end line. - toolSetter.ts: plan.endZ, Phase 6 via raiseToTop with `retreated` / `retreat-skipped` phases, result.finalZ reports where the head was left, header comment and confirm page say so. - tools/toolsetter.ts: description + plan.end_z. - Tests: three #91 cases (below top raises to 328; at top sends nothing; stay_at_trigger holds) - 57 passing. - Docs: README law 9, docs/TOOLS.md, skills cnc-motion-rules (law 8), tool-change, cnc-probing.

One long-lived ffmpeg (or mcpCameraUrl poller) owns the camera only while a browser is attached; its frames feed a FrameHub that fans out to viewers (fps cap, client cap, socket backpressure, stale flag, backoff restart) AND serves every MCP capture through camera.ts's new LiveFrameSource hook, so capture_frame / move_and_capture / visual_servo / survey_bed keep working while someone watches and go back to one-shot captures 5 s after the last viewer leaves. Settings -> MCP Server gains a Camera section: stream on/off (persisted as mcpCameraStreamEnabled, applied at once - off disconnects viewers and answers 404), fps, and the live URL. Default on once a camera is configured. stream_url is reported by list_cameras, capture_frame and get_stored_state. Pure parts (JPEG marker-walking splitter, hub, backoff, enabled default) are unit-tested in tests/mjpegFanout.test.ts; run.ts now awaits async cases. Not hardware-tested: the camera is on the Ubuntu box.

Three operator corrections shape the plan. The camera is session state, not a rig constant - it can move, be knocked or be swapped between power cycles, so pixel-to-machine work needs a pre-configuration stage that bootstraps from nothing. Motion should be allowed at 320 and above, not only at 328. And clearance_z should state the obstacle's own height, with the server adding the live tool protrusion and a margin. The last two are one change: README 594-604 records that the rotary landmark declares 328 because that number had to cover a fitted probe, which is why the floor had to rise to meet it. Separating obstacle height from tool length lets the floor drop, so the clearance basis lands before the floor change. Laid out as a stack of micro PRs - A unblock, B clearance basis, C motion floor, D camera bootstrap and perspective model, E overlap survey and mosaic, F skills and evals - each putting its decision in a pure module with tests under npm run test:mcp.

Governing principles + +**Camera geometry is session state.** + +- Nothing converts a pixel into a machine coordinate, or a machine coordinate into a viewing + pose, until a camera model has been solved *and verified in this power cycle*. A plain + capture is always allowed: a frame FINDS things, it clears nothing (law 3). +- The model is bound to evidence, not to time: a fingerprint (device, resolution, reference + frame hash) plus a connection epoch. A reboot, a reconnect, a different camera or a failed + verification all mark it unverified. +- The bootstrap must work **from nothing** — no assumed direction, offset, field of view or + lens. Doctrine may describe the method; it may never carry the numbers. + +**A clearance is a property of the obstacle, not of the tool.** + +- `clearance_z` states how tall the *obstacle* is. The server adds the current tool's + protrusion and a margin to decide the minimum toolhead Z. An unknown tool resolves to the + longest bit in use, and if even that is unknown the crossing is refused. + +**The motion floor and the park height are different numbers.** + +- The **motion floor** (320) is the lowest Z at which XY transport may happen at all. +- The **park/traverse height** (328) is where procedures hop between stations, retreat on + abort, and finish. Nothing about that changes. + +--- + +## 3. Why the floor and the clearance basis are one change + +From `README.md:594-604`: job 34d787bdb2d7 lost its last op because the `rotary-axis` +landmark declares clearance **328** while the traverse height was then **320** — a hop at 320 +*outside* the rotary footprint was refused. The fix at the time exempted segments at or above +the traverse height from crossing checks, which also let a traverse cross the rotary box with +8 mm of headroom nobody had measured. The operator then set the traverse height to 328 and +removed the exemption. + +The rotary's clearance is 328 because it had to cover a fitted touch probe (~71–73 mm) on top +of the physical hardware. That single number conflates obstacle height with tool length, and +because it conflates them it had to be set to the machine's ceiling — which is why the floor +had to rise to meet it. + +Separating the two numbers dissolves the knot: the rotary box gets its *physical* top, +the checker adds the live tool protrusion plus a margin, and a hop at 320 over clear bed +passes while a hop over the rotary is judged on measured quantities instead of a blanket +ceiling. **This is why B lands before C in the stack.** + +### The risk, stated plainly + +Dropping the blanket floor from 328 to 320 removes 8 mm of *blind* protection — the margin +that guards things nobody has entered in the landmark registry (clamps, stock, vises, +fixtures). After C, an unmapped object taller than ~320 minus the tool length is protected by +nothing. Mitigations built into the stack: + +- The floor is a config value (`mcpMotionFloorZ`, default 320) — one setting reverts it. +- C ships only after B, so the registry is expressed in physical heights and can be trusted + to do the work the blanket floor used to do. +- `get_stored_state.limits` reports both numbers, and the landmark report names every box + still on the legacy basis. +- The operator confirms once that nothing unmapped on the bed stands above the floor minus + the longest bit.

Every traverse-height check already allows that noise (TRAVERSE_Z_TOLERANCE_MM, added after home reported 327.9989959716797 for a 328 home); the obstacle-clearance compare in checkMotion still used 1e-9. The constant moves to envelopeChecks.ts as POSITION_EPSILON_MM - the most primitive pure module, which nothing else imports - and traversePlan's TRAVERSE_Z_TOLERANCE_MM becomes an alias, so its ten call sites are untouched and the two numbers cannot drift apart. The epsilon is noise, not slack: 327.9 over a 328 clearance is still refused.

Live 2026-09-19 that cost a re-home. restore_work_frame sends G90 and G54 on their own lines over the direct path. It carries no axis word, so it is permitted while the position is awaiting-resync or stale, and it reports the position of record before and after, re-read two status periods later. The remedy is also named where an agent actually meets the problem: the refusal from requireReliableMachine now says to call restore_work_frame, why it is allowed, and that a re-home is not the remedy. Both the program and the wording live in frameRecovery.ts so they can be tested - the restore is a legal job that stages cleanly, not a special case carved out of the rules.

A hand-authored file has no such obligation, and on 2026-09-19 one ended in G53: the controller kept the machine workspace, so every later heartbeat carried machine coordinates with the work-origin offset still populated, the position of record rejected all of them, and motion and staging refused until a re-home. The validator now records the frame a file LEAVES SELECTED (frame.endsInFrame, which is the modal state at end of file, not the frame its moves ran in), and resolveJobFrame refuses any job that ends with G53 selected - including one whose moves ran in the work frame and only switched at the end. The refusal names the epilogue it wants; the gcode itself is still never edited. Only submit_gcode_job resolves a frame, so this lands exactly on the hand-authored path it is meant for.

The validator knew exactly what the file should say and made the agent write it out again anyway. suggestGcode() returns a corrected draft for the three edits that need no decision: an inline G53 split onto its own line, a missing G90 added first, and a trailing G54 when the file would otherwise leave the controller in the machine workspace. Anything needing a judgement - which frame an undeclared file meant, whether a G92 was intended - returns null; a suggestion is only offered when it is certain, and it is re-validated before being handed over. validate_gcode reports it as suggested_gcode / suggested_changes, and a staging refusal appends it under "Re-submit this instead". The submitted file is still never edited: this is the program the agent should have written, not a rewrite of theirs. The epilogue is judged on the SPLIT program, because an inline G53 selects nothing - which is the bug being fixed.

Both were staged through submit_gcode_job, which had no opinion about what the file was for. A cnc file that is nothing but transport is now refused at staging, naming the tool that emits the declared, frame-restoring, landmark-checked version. "Transport" is drawn tightly enough that real work is never caught by it: the file must move in XY only or in Z only - exactly what the two tools can express between them - with no spindle, no probing, no arcs, no B rotation, no G92, no relative motion, and no more than eight motion lines. A toolpath, a slicer export or anything that moves in XY and Z together is left alone. The validator gains motionAxes and usesProbing to say this precisely.

Conflating the obstacle's height with the fitted tool has two costs: the number has to be re-stated on every tool change, which nobody does, so it ends up set for the longest thing ever fitted - and it therefore sits at the machine ceiling. The rotary-axis landmark declares 328, the homing height, because it had to cover a ~73 mm touch probe on top of the hardware, and the README records what that cost: job 34d787bdb2d7 lost its last op when a hop at 320 OUTSIDE the rotary footprint was refused against it. Landmarks now carry clearanceBasis. 'physical' states the top of the obstacle itself, so the tool can be added at check time and the number stays true. set_landmark takes obstacle_top_z for that, and keeps clearance_z as the legacy form; giving both is refused, since they are the same number measured to different things. Nothing is re-interpreted: every stored record loads as 'toolhead' and is enforced exactly as before. Reading 328 as a physical height would demand a toolhead Z of 400, so the migration has to be the operator's word, not ours. The check itself is unchanged in this commit.

Nothing reports which tool is in the collet: the tool setter measures one when asked, and the operator declares the longest bit in use and the touch probe's effective length once each. Any of the three could be fitted right now. resolveToolProtrusion takes the longest of them, with provenance. A measurement therefore only ever LENGTHENS the requirement - shortening a clearance on the strength of a measurement that may predate a tool change nobody mentioned is exactly the risky reading. When nothing at all is known the answer is null, never a guess, and the note names the tools that would fix it. run_tool_setter now records derivedBitLengthMm - what the tool actually protrudes, as opposed to the length declared to plan the descent - so the measured candidate exists at all. Measurements written before this carry no derived length and are ignored.

With the touch probe fitted a 250 mm obstacle reproduces exactly the 328 that used to be hard-coded into the landmark; with a 2 mm engraving bit it asks for 257, which is where the machine gets its working room back. A physical obstacle whose requirement CANNOT be computed - nothing known about the tool - is impassable, not passable, and the refusal names the two tools that would fix it. A legacy 'toolhead' clearance is enforced exactly as before and is never inflated by the tool a second time. The direct-move guard had its own copy of the comparison, which is the one that actually fired on 2026-09-19 (move_and_capture -> obstaclesOnPath): it now shares the same requirement and the same float-noise epsilon, so the 327.999994-against-328 refusal is fixed on that path too, not just in the procedure planners. Every checkMotion caller passes the live tool length; traversePlan stays pure and takes it from its caller.

Every landmark now reports requiredToolheadZ - what its clearance actually demands of the toolhead with the tool currently resolved - and says in words where that number came from. Records still on the legacy basis carry the restatement they want, and the summary lists them together with the resolved tool protrusion, its source and the margin, so the migration is visible in one read instead of having to be inferred landmark by landmark. set_landmark echoes the same advice when it writes a legacy clearance, at the moment someone is thinking about that obstacle.

It sits at the ceiling because of the second job - the rotary landmark declares clearance 328 since that number had to cover a fitted touch probe, so the floor had to rise to meet it (README, job 34d787bdb2d7, where a hop at 320 OUTSIDE the rotary footprint was refused). With clearances now stating obstacle heights and the tool added at check time, the two separate. safeTraverseZ stays the park height at 328; motionFloorZ is new, defaults to 320, is clamped to never exceed the park height, and is what law 2 is enforced against - traverse_xy, move_and_capture, survey_bed and the tool setter's travel to the setter. Hops, retreats, probe start heights and every procedure's ending are untouched. The traverse-height exemption from crossing checks stays REMOVED: a hop at the floor is checked against every stored box exactly like any low segment, which is what makes a floor below the park height safe at all. planTraverseXy also stops planning its segments at the park height and plans them at the height the toolhead is actually at (snapped up only by the heartbeat's float noise). That was harmless while the floor WAS the park height and wrong the moment transport is allowed lower - it would have checked a corridor the toolhead was not in. Residual risk, stated plainly: 8 mm less blind protection for anything on the bed with no landmark. mcpMotionFloorZ is the one setting that reverts it.

It can sit differently after every power cycle, be knocked, be re-aimed, or be a different camera entirely. So camera geometry is session state. CameraModel carries where the camera is (offset and rotation relative to the toolhead), what it sees (intrinsics, with k1 only when the targets constrain it), the Z band its poses actually covered, its residuals, and a state that says whether any of it may still be used. judgeCameraModel decides that on evidence rather than age: a different camera or a different resolution needs a full bootstrap; a reconnect needs a verification, because nothing about a camera survives a power cycle on trust; and a model that has only ever agreed with the data it was fitted to has demonstrated nothing, so it stays unverified until it passes a pose that was not in its own fit. An unnamed device is unknown, not different - an MJPEG URL names none. A new solve never overwrites the old one: the previous model is kept superseded with its residuals, so "was the camera moved between these two jobs?" stays answerable afterwards. Nothing consumes the model yet; this is the type, the store and the judgement.

It guessed from a remembered "the camera looks -X, 90-150 mm", moved 30 mm to find out, and spent three operator approvals establishing a sign. cameraGeometry answers it from the model: viewPose returns the toolhead position that puts a machine point dead centre, whatever direction the camera looks and whatever the tilt, with the standoff it implies. machineToPixel and pixelToMachine are inverses of each other on a STATED Z plane - the plane is always an argument, never a guess, because a single frame cannot say how far away what it sees is, and assuming one plane for a feature on another is what read ~4x wrong on the board. fovAt measures the real footprint across the frame's own corners, which is what makes an overlapping survey computable at all. jacobianAt regenerates the legacy 2x2 so visual_servo is untouched - that matrix was always this model linearised at one Y and one Z, it just had no model to come from. Everything works in machine coordinates, which is why one rigid transform is enough: the gantry carries X and Z and the platform carries Y, but the machine frame is the tool relative to the work, and in it the camera centre is the toolhead position plus a fixed offset. Nothing converts through a model that is not verified, a pixel outside the region the fit constrains is refused rather than silently converted, a point behind the camera is reported as such, and a toolhead Z outside the band the poses covered is flagged as extrapolation.

A stored model is always UNVERIFIED: agreeing with the data it was fitted to demonstrates nothing. verify_camera_model is what makes it usable - it predicts where a target of known machine coordinates should appear at the current toolhead position, compares that with where it actually appears, and records the residual in pixels and millimetres. Beyond tolerance the model stays unverified and the note says plainly that the camera has probably been moved and that no pixel should be converted through it meanwhile. It is also the first camera call of any session, which is the point: a model is bound to a connection epoch, so a reconnect demands this check before anything trusts the geometry again. No motion - position the toolhead first. requireCameraModel is the gate the pixel-consuming tools will use.

"search" is the step that needs no calibration to mean anything, which is why it comes first: a serpentine grid at the park height across the X band the camera could be looking from, bracketing the tool setter, whose machine XY is known exactly. Which frames contain the setter, compared with the toolhead XY of those frames, gives the camera offset INCLUDING ITS SIGN with no prior assumption whatever. The 2026-09-19 session reached the same grid only after forty minutes of single poses and an assumed offset that pointed the wrong way. "poses" visits the poses that coarse offset implies and sweeps Z from the park height to the motion floor with XY STATIONARY - a vertical baseline, not a diagonal through unknown space - capturing at every stop. Targets at different heights over that baseline are what turn a flat pixels-per-millimetre figure into perspective. The planning is pure and tested. Transport is always at the park height and the head returns there before the next XY move; a descent is segmented and crash-guarded like any other. The camera looks into keep-outs on purpose, but the toolhead does not enter one: a pose it cannot reach is dropped with a reason, a sweep that would descend into a box keeps the stops above it, and nothing is ever quietly adjusted. For a descent every obstacle is judged as a volume - the 'crossing' exemption is for probing inside a footprint, not for looking at it. A bootstrap with no target of known machine coordinates measures nothing, so that is a refusal naming the tools that would fix it.

Ten unknowns - the camera's offset from the toolhead, its orientation, and a pinhole's fx/fy/cx/cy - fitted against sightings of points whose machine coordinates the machine already knows: the tool setter's centre and plate top, the rotary axis line and its named ends. It refuses to call a fit a solve when it is not one. Fewer than six observations, or fewer than three distinct poses, is a refusal that says why: the offset and the focal length trade off against each other from a single standoff, which is exactly what the Z sweep exists to separate. Detection is optional and deliberately conservative - a wrong detection is worse than none, because the fit believes it - so hand marks are a first-class input and always win. k1 is never fitted here: a distortion term from a handful of points would be noise wearing a physical name, and the cost is carried honestly by central_region, computed from how much of the frame the targets actually covered. --self-test recovers a known model from synthetic sightings, then does it again with the marks jittered by 1.5 px, because a solver that only works on exact input is not a solver for this. The half-turn case in the Rodrigues inverse is handled explicitly: a camera looking straight down at a bed IS a half-turn from the identity, so the naive form divides by zero on the most ordinary mounting there is.

Given an overlap, the pitch is computed from the model's real footprint on that plane: pitchForOverlap is pure and tested, including that a 30% pitch really does leave about 30% shared. An absurd overlap is clamped rather than producing a pitch of nothing, and pitch_mm still caps the result. It needs a VERIFIED model and says so - the field of view is the whole basis of the number, and guessing it is exactly what this replaces. plane_z is stated, never inferred: a frame cannot tell how far away what it sees is. The envelope the operator approves carries the pitch and where it came from, including a warning when the Z is outside the band the model was solved over.

It had to stage that as a separate job, which then could not be withdrawn, and the agent ended up telling its operator in prose not to approve it. survey_bed takes z_levels: up to six full passes of the grid, highest first, one approval for the series. Each level is entered with XY STATIONARY, so the survey is a stack of flat passes and never a diagonal through unknown space, and every level must be at or above the motion floor unless the operator has explicitly said otherwise - the refusal names the levels that are too low rather than silently clamping them. Frames carry their own Z and the index lists the levels, so a mosaic can be built per plane.

Once every frame is placed where the model says it belongs, "the hole is at mosaic pixel (u, v) on plane Z" becomes a lookup through the index's own affine - instead of what the 2026-09-19 session was reduced to, which was inferring a position from one frame and a remembered scale that turned out to have the wrong sign. One mosaic per Z pass, written beside the frames, with its machine bounding box, its millimetres per pixel, the pixel-to-machine affine and the fraction of the canvas no frame covered. Machine Y runs UP the picture and the affine says so. Each frame is drawn by inverse mapping over its own footprint: for every mosaic pixel it could cover, the model is asked which of its pixels that machine point projects to. Hole-free where a forward splat would leave gaps, and it costs the mosaic's area rather than frames times pixels. A whole-bed mosaic is coarsened rather than refused - the scale gives way, not the coverage. Seams are not blended. A hard edge at the right coordinates says more than an average of two disagreeing views, and where two frames disagree that is evidence about the camera rather than something to smooth over. Without a verified model there is no mosaic and the index says so, naming camera_bootstrap; the frames themselves are still all there.

Comparing them costs nothing during the render and is the only free evidence available about whether the model still describes the camera. A pure brightness difference is not disagreement - auto-exposure does that between any two frames - so it is subtracted before judging. What is left is structural: the same ground landing in different places, which means the camera was knocked, re-aimed or swapped since the model was solved. Past the threshold the model is marked unverified there and then, with a note naming verify_camera_model and camera_bootstrap. Too little shared ground is inconclusive, never a pass and never a condemnation: the note says so and points at overlap_fraction.

The skill says plainly that the floor could only drop once clearances stopped carrying tool length, that there is still no exemption for being high, and what it costs - 8 mm less blind protection for anything on the bed with no landmark. Law 4 becomes the obstacle's own height: state obstacle_top_z, the server adds the fitted tool and a margin, a measurement only ever lengthens the requirement, and an unknown tool makes a physically stated obstacle impassable rather than passable. With the probe fitted a 250 mm obstacle still demands 328; with a 2 mm bit it demands 257. The position-of-record section gains the case that cost the 2026-09-19 session: a controller left in the machine workspace, which no amount of waiting fixes, is recognised after three beats and cured by restore_work_frame - not by a re-home, which only works by accident because it emits a G54 on the way. And the hygiene that stops it: every machine-frame job hands the frame back, which is the real reason to use traverse_xy and move_z rather than writing the file yourself.

On 2026-09-19 an agent followed it, went to toolhead X 290 for a feature at X~170, moved +30 mm to check, watched the workpiece slide further out of frame, and was corrected to "260 is about the max" - three operator approvals to establish a sign that one measurement settles. That section is gone. In its place: the camera is session state, so verify_camera_model is the first camera call of every session, with a table of what each outcome means and which tool fixes it; camera_bootstrap solves the geometry from nothing in two stages, the first of which needs no calibration to mean anything; and plan_view_pose answers "where must the toolhead go to see this" from the measured model. The old number survives only as the cautionary tale, quoted as the thing that was wrong. The survey section leads with "survey first, single poses second" - the same session found what it wanted in the first grid it ran, after forty minutes of single poses - and documents overlap_fraction, z_levels, the machine-indexed mosaic and the seams as the drift check.

"view-unfamiliar-workpiece-and-map-its-top" checks that a model solved two days ago is verified before any pose arithmetic, that a survey beats a chain of single poses, and that a position is read off the mosaic rather than inferred from one frame and a remembered scale. "camera-knocked-and-controller-stuck-in-g53" puts both of the 2026-09-19 faults in one prompt and grades diagnosing them separately, curing the position with restore_work_frame rather than a re-home, and not computing a pose until the camera model is verified again. Every eval gains two assertions: transport at or above the motion floor with the park height kept distinct, and no assumed camera offset, field of view or viewing direction. Eval 0 loses the hint it used to carry - "the toolhead camera looks -X and sees ~90-150 mm to its -X side". Handing an agent that number is exactly the mistake being fixed, and grading it on following the hint would have rewarded the behaviour that cost the session. The visual-alignment description no longer advertises Y-keyed calibration as the mechanism. These are the scenarios, not a rerun: the fresh-agent evals across Opus, Sonnet and Haiku still need running against the new skills.

18:52:03 +0100 Subject: [PATCH 112/135] Docs: The tool reference carries the new surface Six tools were added across this stack and none of them was in TOOLS.md, which is the file an agent reads to find out what exists. Discoverability is not a footnote here: the 2026-09-19 session hand-wrote transit gcode while traverse_xy sat unused, and reached a camera grid only after forty minutes of single poses. Adds restore_work_frame beside the direct-motion tools, a "the camera model" section that leads with the camera being session state rather than a rig constant, and the new survey_bed arguments - overlap-derived pitch, z_levels, the machine-indexed mosaic and the seams as a drift check. The plan doc records what was built and, as plainly, what was not: the fresh-agent eval rerun, and any exercise against the live machine, which was not reachable from this session.

From b9479114337e45d6a208b00bdb587ac4fb956689 Mon Sep 17 00:00:00 2001 From: tyeth Date: Sat, 19 Sep 2026 21:28:48 +0100 Subject: [PATCH 113/135] Fix: Say what a dead probe feed means, and for how long it has been dead Live 2026-09-19 on the box: the KB2040 U2IF bridge enumerated on USB, Blinka resolved its board id, and the first digitalio.DigitalInOut() never returned - the bridge was wedged. The transport reported "GPIO monitor produced no ready line within 30000 ms" and retried quietly for eighteen minutes. Nobody saw anything: the machine was not connected, so the Workspace pills were not on screen, and the only other signal was connected:false among forty fields. Probing was never unsafe - assertChannelReady already refuses without a live feed - but finding out when you try to probe is not good enough for a sensor whose whole job is to be watching. Two changes, both about saying what is true: The monitor now emits progress as it comes up (imports done, each pin configured), so a ready timeout can be classified. "Blinka loaded and the bridge answered as KB2040_U2IF, but configuring the first pin never returned - the board is enumerated on USB but not servicing requests; UNPLUG AND REPLUG it, nothing in software can reset it" is a different fault from "the interpreter produced nothing, check the venv and adafruit-blinka", and the old message covered both. And the status carries a sentence: how long it has been down, how many attempts, what it blocks (every probing procedure and tool-setter run, because the overtravel tripwire cannot be armed without it) and that nothing needs restarting once the physical cause is fixed. It rides on get_stored_state, which is the call every session is told to make first. The judgement is pure and tested, including that a wedged bridge is never told to reinstall Blinka and a failed import is never told to replug the board.

That was wrong, and the operator said so: it is a previous instance not releasing its reference. Confirmed on the box. `lsusb -t` showed the KB2040's HID interface as Driver=[none] instead of Driver=usbhid - a libusb claim that a monitor killed by the 30 s ready timeout never reattached. The board still enumerated and `import board` still resolved KB2040_U2IF in about a second, which is why this looked like dead hardware; only the first digitalio.DigitalInOut() blocked. USBDEVFS_RESET on the device node fixed it outright: before If 2 Class=Human Interface Device, Driver=[none] after If 2 Class=Human Interface Device, Driver=usbhid pin configuration 40 s+ hang -> 1.17 s, D2 idle as documented No root needed - the node carries a plugdev ACL - so the transport now does it itself. On a ready timeout that carries the leaked-claim signature (board loaded, no pin configured) it resets the bridge and retries, and the error says what it did. Node has no ioctl and this transport already requires a Python interpreter, so the reset runs there. The scan is deliberately narrow: only known U2IF vendors, and only a device whose HID interface actually has no driver bound. Resetting USB devices at large is not this module's business. Non-Linux hosts skip it rather than failing - the retry is still what recovers. Verified against the real device in its healthy state: the helper finds the KB2040 and correctly declines to reset it, "HID interface still bound to its kernel driver".

They were built on 2026-09-15 and never rebuilt, so while this branch carries the corrected camera doctrine in SKILL.md, the packaged copies still told an agent "the camera looks -X, seeing roughly 90-150 mm to the toolhead's -X side" - the exact folklore that cost the 2026-09-19 session three operator approvals and sent the toolhead the wrong way. Rebuilt from the sources in this branch. The visual-alignment package also gains scripts/camera_bootstrap.py, which was never in it, and the motion-rules package picks up the two new eval scenarios. Built with a sorted walk so the archives are deterministic: a diff between two builds means a real content change rather than a reordered directory listing. Checked by reading back out of the archives - the old arithmetic appears zero times as an instruction and survives only inside the paragraph that quotes it as the thing that was wrong.

[PATCH 116/135] Feature: Choose the camera by looking through it, not by editing a config key Two cameras have been attached to the Ubuntu box since the second one appeared, and the whole hazard is that both return perfectly good frames. A picture from the wrong camera is not an error anywhere: it decodes, it template-matches, and every millimetre measured through it is wrong. Until now the only way to pick between them was for the operator to edit mcpCameraDevice by hand - and there was no way to see what a camera looked at before pinning it, because capture_frame only ever opens the configured one. preview_cameras takes one frame from EACH attached camera, labelled with its device string and frame_id. A camera that will not open is reported beside the others rather than replaced by a substitute frame, and the selection is left alone - it is a look, not a change. select_camera pins the choice (mcpCameraDevice, or mcpCameraUrl for a snapshot URL; picking one clears the other, since the URL wins wherever both are set). It requires confirm_frame_id: a frame that provably came from THAT camera. Frames now carry the device they were captured from through the frame cache, so evidence from the other camera is refused by name instead of being taken on trust. The proof is waived only where there is nothing to get wrong - one camera attached, or re-pinning the one already in use - and operator_confirmed remains for the operator's own word. The call returns a fresh frame from the camera it just selected, so the selection verifies itself. Device matching resolves an entry, a /dev path (the by-id symlink or the node it resolves to), a friendly name, or a substring that names exactly ONE camera. Two matches is a refusal listing both, not a coin toss, and a bare index is refused outright: neither /dev/videoN numbering nor enumeration order survives a replug. Changing camera invalidates the solved camera model on the spot - that geometry belonged to the old camera - rather than waiting for the next call that happens to pass a fingerprint. requireCameraModel judges without one, so a swap would otherwise have gone unnoticed. verify_camera_model now compares the device as well as the resolution, so a model solved for the other camera cannot re-verify itself on a lucky residual. Supporting changes: capture from a named device without touching the sticky choice (a preview never becomes the last-good fallback); candidate enumeration that is not hidden behind a set mcpCameraUrl; the stream loop reports which device it holds, so previewing the streamed camera is served from the loop that already has it open, and a new selection restarts the loop onto it for whoever is watching. The matcher is pure and unit-tested against the real two-camera listing (14 cases). Docs, TOOLS.md and the cnc-visual-alignment skill updated - its row still said the operator pins mcpCameraDevice - and the packaged skill zip rebuilt. Not yet exercised against the hardware: the MCP connector was refusing connections.

No such file or directory which is true and useless. It does not say which cameras ARE attached, and it reads like a broken camera rather than a stale choice - the cure is a new selection, not a new camera. A pinned device is deliberately not checked against the device list on the happy path: enumeration costs an ffmpeg spawn on Windows, on every single capture. So the list is fetched only once a capture has already failed, and only to answer the question the failure raises. A pinned camera that is no longer attached now gets: The selected camera "..." is not attached any more. Attached now: "...", "...". Run preview_cameras to see what each one is looking at, then select_camera to choose one - refusing to silently substitute a different camera. (ffmpeg: ...) An empty device list is NOT treated as evidence the camera vanished - that means enumeration itself failed, and claiming otherwise would send someone hunting the wrong fault. The ffmpeg text is kept either way: it is still the proximate evidence. The two older hints that told the operator to set mcpCameraDevice by hand now point at select_camera, which is the thing that exists to do it. Decision logic is pure and unit-tested (4 cases, including the empty-list one); 199 tests pass.

Asking for the default reach of 200 mm around a tool setter at X79 planned a first waypoint at X-25: six millimetres past the end of the machine, discovered on the first move of a procedure the operator had already approved. A y_span of 100 did the same at Y343 against a 342 limit. Nothing in the MCP knew where the toolhead can go. checkMotion checks obstacles; the position of record checks beats against the machine-definition size with 50 mm of slop, which is a sanity filter for garbage readings and was never a statement about reachable travel. So a planner wanting a band to sweep had nothing to clamp against and invented one. machineTravel.ts resolves it in three layers, strongest first: STATED travel_x_min / travel_x_max / travel_y_min / travel_y_max in the geometry store (set_probe_geometry, env-overridable) - the measured limits for THIS rig. OBSERVED a position the toolhead has actually occupied is proof that point is reachable, so it widens an end nobody has stated. Home is the usual source: an A350 sitting at X-19 has demonstrated X-19. NOMINAL the machine definition's size box. Evidence never overrides the operator: an observed position outside a STATED end is reported as a conflict rather than silently widening it, because one of the two is wrong and a planner should not pick which. This is dynamic because machines are. An A350's definition says 320 x 350 while its frame runs X -19...339 and Y 0...342; an A250, an Artisan, a bracing kit or a firmware limit found by sweep all move the numbers. Unknown machine with nothing stated = no honest box, so the planner REFUSES and names the tool that fixes it rather than guessing a band. clampBand() then clips the requested reach into that travel and reports what it lost, per end, in millimetres. The reach is symmetric but a machine is not: this rig's tool setter sits 98 mm from the X minimum and 260 mm from the maximum, so a 200 mm request cannot be honoured evenly - and a planner that quietly halves it leaves someone wondering why the camera was never found. The staging result now carries travel, travel_sources (stated / observed / nominal per end) and a clipped[] explanation that also reaches next_step. 14 unit tests covering both edges, both-ends overrun, a target near the far edge, a zero span, a target outside the travel, an inverted travel, and the stated-vs-observed conflict. 213 tests pass.

The same envelope was written out by hand in ten more places, and two of them clamped silently. Now every planner asks requirePlanningTravel() (stated -> observed -> nominal, machineTravel.ts) and checks its points with assertWithinTravel(), whose refusal names the point, the axis, the overshoot and which layer the limit came from. The two silent clamps report: - probe_point / probe_vector marches are shortened with clampRay(), and the plan carries travelClippedBy onto the confirm page - a face beyond a shortened march would otherwise read as "no contact"; - survey_bed clamps stated bounds INTO the travel with clampBand() and returns `clipped` (also on the confirm page); its defaults are the travel inset by margin_mm rather than the nominal box. traverse_xy's planner takes TravelLimits instead of a nominal box plus the XY_BOUNDS_*_MARGIN_MM constants, which are gone. move_z's Z ceiling is the higher of the definition and the park height, not size + 40. All comparisons tolerate the heartbeat's float noise (TRAVEL_EPSILON_MM).

Safe that day only because the motion floor sat high relative to the bed's contents, not because anything checked. surveyPlan.ts (pure, six tests) plans the legs against every stored box as a volume, the way the camera pose sweep does - a camera can look from above: - a waypoint whose descent column into a level hits an obstacle is DROPPED from that pass with the reason (result.dropped, the confirm page, the survey's index.json); the serpentine index is kept so the gap in the frames is explained; - a link between kept waypoints that would cross a box at the level is LIFTED: raise with XY stationary, hop at the park height, descend at the destination - each its own gcode line, counted as lifted_links; - a link that fails even at the park height drops its destination; - only a grid with nothing left to capture is refused. Levels are entered by hopping at the previous height and descending at the first waypoint (or raising first when the new level is higher), so the grid stays a stack of flat passes. The runner executes the approved legs rather than the raw waypoint list. The description's stale "machine Z >= 250" is replaced by the motion floor it actually checks.

Every cap a planner applied to its arguments lived inline - `Math.min(Math.max(Number(args.x) || 1, 0.2), 1)` in eight planners, `> 150`, `> 400`, `120000`, `* 4, 3500`, `0.15` through the tools - so a reader could not tell a deliberate variation from a copy-paste drift. procedureLimits.ts (pure, eight tests) names each as { default, min, max } with its reason, and clampTo / clampCount / within / resolveMarchParams replace the idiom. Semantics are unchanged except: - probe_circle's coarse step cap drops from 2 mm to the 1 mm every other planner already obeyed (operator law 2026-09-05: never 2 mm); - the backoff floor follows the CLAMPED fine step rather than the raw argument (a fine step asked at 5 is 0.5, and so is the floor). Deliberate variations are named as their own Bounded next to the shared one: SURFACE_COARSE_STEP_MM (0.5 floor), GPIO_SENSOR_DELAY_MS (30 ms floor, jobs 1db4/d8f6), the tool setter's backoff / delay / release timeout, probe_circle's default and confirm passes. The heartbeat tolerance stays POSITION_EPSILON_MM / TRAVEL_EPSILON_MM, as before.

The operator law of 2026-09-05 ("never 2 mm") is about the PHYSICAL move: a G1 toward the work cannot be stopped once sent, so the press into the probe is the whole move. Every coarse ladder treated coarse_step_mm as that move - one G1 per step, one sensor read after it - so the only way to bound the press was to cap the step, which is what made probe_circle's 2 mm radial advance look like a violation. probing.marchInSegments(move, fromS, toS, channels, sensorDelayMs) turns any march advance (a scalar along a unit vector, one axis coordinate, a Z) into settle-verified moves of at most MARCH_SEGMENT_MM (1 mm), each followed by its own senseAfter window, stopping at the segment a contact is sensed on - a 2 mm step that meets the surface 0.6 mm in reports 0.6 mm in. The pure planner marchSegments (procedureLimits.ts) divides the advance evenly with the end exact and is unit-tested. Every coarse ladder goes through it: marchToContact (probe_stock_outline, run_probing_gcode, probe_program ops), probe_point, probe_vector, probe_sequence, probe_circle, the surface scans' coarse/fine ladder, and the tool setter's coarse descent. Retreats move away from the work and stay whole; fine steps are already below the segment. The confirm pages say the moves are segmented. The coarse caps are unchanged: they bound the logical advance, and probe_circle keeps its 2 mm.

Result carries elapsedMs, expectedMs, settleWaitMs and how it was verified. - probing.awaitMachineSettled: the shared idle-and-B gate. - probeProgram capture op: waits for that gate before every frame, and again after its own view hop (operator: "any camera op should await the previous op's position confirmation first").

Job 96baca79b3b8 (a capture op viewing from machine (190, 140)) broke that: the runner's raise-to-Z328 and XY hop were prose comments, the body's only motion line was the closing raise, and the page read X/Y extents "-", Frame UNDECLARED, Z extents MACHINE UNRESOLVED, plus a genuine "motion before any G90/G91" warning. - programEnvelope.ts (new, pure): the probe_program body as ONE declared machine-frame block - G90, G53; before the first move, every op's commanded lines inside it, the closing raise, G54; after. A capture with a viewing position renders the two moves moveMachineSettled will send (G1 Z F600, G1 X Y F600); a rotation renders its G0 B; a closing home renders G28. Sub-plan previews are embedded without their own G90/G53;/G54; wrapper, which also ends the false "mixed frames" warning on every program whose last op was a scan, sequence or outline. - tools/staging.ts (new): validateStagedEnvelope() runs every server-emitted body - all procedures and direct moves - through resolveJobFrame(), so the page's Frame row and machine-resolved Z extents are filled for them as for a submitted file (they were always "UNRESOLVED - see warnings" with nothing to see). A body that would be refused from an agent is an emitter bug and is thrown, never shown. - probeCam.ts, probeOutline.ts: run_probing_gcode and probe_stock_outline envelopes now hand the frame back with G54; like every other emitter. - validator.ts: G28 is reported (usesHoming + warning) since the extents cannot include homing travel. - jobs.ts: the SERVER-DRIVEN banner and heading say the lines are the plan the runner will command, computed into the table, never streamed. - procedureLimits.ts: TRAVEL_FEED / COARSE_FEED / FINE_FEED move here (pure) and are re-exported from probing.ts. - tests: programEnvelope.test.ts (10 cases incl. the 96baca79b3b8 regression), validator G28 case.

Work (0, 0) is resolved through the heartbeat's origin offset at staging and the move is planned - motion floor, toolhead travel, landmark crossings, all against the RESOLVED machine destination - and emitted in MACHINE coordinates (G90 / G53; / G1 X Y / G54;), so the confirm page shows where the head actually goes and the approved job goes exactly there even if the origin is re-zeroed before start. Refused while the origin offset is not the heartbeat's own reading or the position of record carries warnings; assertSafeToMove (overtravel, fresh + reliable heartbeat, idle, toolhead off, homed) applies with no override. The operator_confirmed_clearance switch and the on-arrival frame are gone from this tool; the confirm page is the operator's word. - move_and_capture is Z-gated FIRST (gateDirectXy). Before any XY is commanded: unknown machine Z refuses; a head below the safe traverse height (mcpSafeTraverseZ, Z328) is raised straight up first - a Z-only G53 move, awaited to two matching heartbeats - and the XY is sent only once it has settled; landmarks are checked at the Z the XY will actually run at. Before: the check compared against the motion floor, ran after the travel cap, and was skipped outright when machine Z was null. Ordering after: args -> reliable position + safety -> travel cap -> channel -> Z GATE (refuse / raise / proceed) -> landmarks at planZ -> travel -> pacing -> XY. operator_confirmed_clearance remains the one escape hatch (XY at the current Z, no raise); it does not lift the unknown-Z refusal. - home: implementation untouched. cnc-motion-rules SKILL.md law 6 no longer lists home among the staged tools and states that home and move_and_capture move on the call itself; law 1 / the checklist ("homing is itself a motion", needs the operator's word, homes B) and the vocabulary (G53;G28;G54) are kept coherent; goto_work_origin joins the staged list; section 4, 5 and 8 updated. cnc-motion-rules.zip rebuilt with a sorted walk. Visual-alignment skill and TOOLS.md tool lines updated. - tests: directMovePlan.test.ts (10 cases: the gate's four branches, the machine-resolved destination on the page, cached/assumed offset and warnings refused, travel and landmark checks against the resolved point, the floor).

Operator ruling 2026-09-21: the motion floor is the right gate. gateDirectXy now takes floorZ and the call site passes motionFloorZ(). The threshold and the raise target move together: the floor is the height a direct XY may run at, so it is also where a low head is raised to. Landmarks are still checked at planZ, so anything needing more height (the rotary landmark's clearance 328) is still refused rather than driven through. goto_work_origin is unchanged - it is a staged move, where law 2's traverse height applies.

Over a top that is right (the surface is higher here); inside a pocket a lateral contact is a WALL, and job f84f2a263333 (2026-09-21) climbed onto the rim in two 2 mm lifts, then the guarded descent at the destination met the top face and the runner raised a CRASH alarm with the tip held on the wood (issue #167). Now (camLinks.ts, pure): every XY link is classified by the station it heads for. link_mode "stepped" picks per link - a link toward a SIDE-MARCH station (|z| of the G38.2 direction < 0.5) is a WALL link, toward a -Z station a TOP link; link_mode "wall" forces the wall behaviour. A wall link's first contact backs off 1 mm, retreats hop_lift_mm further along the REVERSE travel vector (the only proven-clear direction, capped at the link start, never +Z), is recorded as a `link_contact` (tip centre, travel direction, the station it was heading for) and marks that station `blocked`: the approach moves up to it are skipped, its cycle records status blocked with blockedBy, and the run continues from where the head is. A contact during the guarded descent at a stepped link's destination is a blocked station too: 1 mm back, release check, straight back up the column to the link Z, continue - sensed serially with the contact expected, so the async crash latch no longer force-closes the connection. Raise-mode descents keep the collision semantics unless the new top_z_machine (a MEASURED top) says the contact is AT the top within one guarded step. top_z_machine also caps top-style +Z lifts at the top, so a lift that would leave the pocket blocks the station instead. Every +Z lift that went on is recorded as a link_contact too. marchCore.ts holds the stepped traverse and the link descent against a small IO interface, so both run under ts-node on a fake machine: reverse-vector retreat with no Z change, retreat capped at the start, +Z lift-and-retry, top-capped lift -> blocked, descent contact -> blocked (never below the contact, expected set only for the guarded steps), raise-mode descent contact -> abort with the law-8 raise decision, target reached. camLinks tests use the pass-2 program tail (px_lw_8 -> px_lw_9 -> px_ew_1) and the emitter's top shape. march.ts binds the cores to the engine; probeOutline's stepped traverses are unchanged in behaviour. The confirm page names the link style, the station, the retreat direction and the blocked outcome on every link, and the report gains linkContacts, summary.blocked and CSV rows for the link contacts. The abort path is unchanged: straight up to the traverse height, held only while the probe still reads contact (law 8).
