build ritual: antivirus smoke test before shipping a zip (#190 ). Windows Defender's ML classifier flagged btl4.exe as Trojan:Win32/Bearfoos.A!ml and DELETED it -- a false positive, and crucially PER-BINARY rather than per-project: of 17 archived builds extracted side by side only 4.11.957 was condemned (622 through 913 all survived), plus that evening's fresh build. Our exe fits the profile that trips these classifiers (unsigned, rebuilt every session so it never accrues reputation, raw sockets, process enumeration, writes beside itself), so each build is a coin flip; and it turns WITHOUT a code change -- the same binary ran clean across benches all evening, then the 8/14 19:34 signature update (1.457.172.0) condemned it hours later, which is why the field was quiet: nobody had launched since. Ritual added: extract the new exe OUTSIDE any Defender exclusion, wait ~60s (deletion is asynchronous -- an immediate Test-Path passes and the file vanishes a minute later), confirm it survives, and if not, submit to Microsoft as a false positive before shipping. Notes that a rename cannot help (content is what is scored; the exe name is constant, only the zip is versioned) and that an exclusion on the repo makes the test silently pass.

+# The playtest tracker sheet
+
+Since **2026-08-14** the testers track issues in a shared Google Sheet instead of the annotated
+`docs/OPEN_ISSUES_FOR_TESTERS.txt` handout. It is now the **primary feedback channel**; edited
+.txt docs and pasted Discord logs are secondary ([[operator-console]] covers the session tooling
+itself). The sheet is the testers' INPUT surface; **gitea remains the system of record.**
+
+## Shape
+
+Two tabs. Sheet ID and the write-bridge credentials live in the operator's local Claude memory
+(`feedback-channels`), **never in this repo** — the bridge URL + token together grant write
+access to the sheet.
+
+- **OPEN** — `# | Priority | Test Status | Dev Status | Dev Comments | Tester Comments`,
+  ONE row per ticket, sorted by priority then ticket number.
+- **CLOSED** — the same minus Priority, ascending by number. Also holds non-ticket records
+  (completed audits) under a text key like `AUDIT`.
+
+**The split is driven by GITEA STATE, not by the Dev Status column** — the two drift constantly,
+and the sheet's own column is the stale one.
+
+## Dev Status vocabulary (dev-owned column)
+
+The colour is **embedded in the label**, not applied as a cell fill:
+
+| Label | Meaning |
+|---|---|
+| `🟡 PATCHED - RETEST` | code landed, needs a playtest to confirm — the testers' retest list |
+| `🔴 FAILED RETEST` | a shipped fix did **not** hold; back on the bench (never collapse this into QUEUED — it understates a regression as "not started") |
+| `🟠 NEED INFO` | blocked on testers for a repro, detail, or log |
+| `🔵 YOUR CALL` | not a code question; needs their opinion or era memory |
+| `⚪ QUEUED` | logged and understood, work not started |
+| `🟢 WORKING` | actively being worked right now |
+| `✅ DONE` | verified — **only ever appears on CLOSED** |
+
+Priority: **P1** blocks a session / hits everyone · **P2** gameplay correctness confirmed in the
+field · **P3** presentation and polish · **P4** era question or opinion call · **P5** latent or
+internal with no field impact.
+
+Test Status is TESTER-owned (`Pass` / `Fail` / `Test` = not yet retested / `Rework` / `Clarify`).
+A **Fail on a ticket gitea has closed** is the highest-value signal in the whole sheet — it means
+a shipped fix did not hold, or the tested build predated it.
+
+## The Dev Comments contract
+
+That column is what a player reads, so it is written for a player, in three lines:
+
+```
+<one sentence: what is wrong, or what changed if patched>
+STATUS: <where it actually stands>
+NEED FROM YOU: <a concrete, specific ask>      <- omit for QUEUED
+```
+
+Under ~55 words, no addresses, no engine jargon. The ask must name what to capture (which mech,
+which map, what time, what you expected vs saw, the boot-screen build number) — never "let us
+know if it happens again". If the thread already answers it, do not ask again.
+
+## Working rules (learned the hard way)
+
+- **Read the gitea COMMENT THREAD, never the body alone.** Bodies are original reports and are
+  routinely superseded, retracted, or already fixed by comment 4. Triaging 53 tickets from
+  threads moved a third of the statuses and dropped P1 from 5 to 2. See
+  [[reconstruction-gotchas]] for the general form of this mistake.
+- **DATE EVERY TESTER ENTRY: `M/D - ` at the front of each line.** The build is cut per session,
+  so the date implies the build — which is what makes a Pass or Fail interpretable at all.
+  Entries carried over from before this convention are marked **`(undated)`**, meaning
+  *provenance unknown — do not treat as fresh evidence*. That marker is deliberate: the sheet was
+  seeded from earlier tracking and nobody can now say which rows are original, so stamping them
+  all with the session date would manufacture precision. Reading undated rows as fresh already
+  produced a false "still crashing after the fix" claim on #170 that had to be retracted across
+  seven tickets — #170's row carries the same three timestamps and players as its own 2026-08-12
+  body, and whether that is a copy-forward or a genuine recurrence is STILL UNRESOLVED.
+  One entry per line, each with its own stamp; comment cells grow over time and undated text
+  running together is unreadable within two sessions.
+  An undated entry CAN often be dated from gitea: if its text is quoted in a ticket body, the
+  report existed by that ticket's creation date (this is how #170's three crash lines were pinned
+  to 2026-08-12 — its body says `FIELD 2026-08-12` and lists those exact times).
+  ⚠ **SELF-REFERENCE TRAP:** do not date an entry from a comment YOU wrote while harvesting the
+  sheet — those quote the tester text verbatim, so a naive search dates the report to your own
+  housekeeping. Exclude same-day comments and take the EARLIEST match. This bit once already: a
+  #170 line was briefly stamped with the harvest date instead of the event date.
+- **Never write `DONE` on OPEN.** A row that is done belongs on CLOSED; a `DONE` on the open page
+  is a contradiction that confuses everyone reading it.
+- **Merge duplicates to one row per ticket** — linking loose reports to existing tickets creates
+  two rows for the same number otherwise.
+- **Never use cell fills for status.** Fills belong to cells, labels to text; every re-sort moves
+  the text and leaves the paint, so they desync. This was re-fixed three times before the colour
+  was embedded in the label.
+- **A leftover FILTER hides rows after a rewrite** — if rows appear to vanish and the row numbers
+  in the gutter SKIP, that is hidden rows, not lost data (Data → Remove filter).
+- **Row heights**: autofit makes wrapped comment rows hundreds of pixels tall (≈4 visible rows).
+  Pin to ~63 px.
+
+## The cycle
+
+1. **Before a playtest** — regenerate/refresh: reconcile every row against gitea, clear stale
+   statuses, make sure each `NEED INFO` carries an ask the testers can act on that night.
+2. **After a playtest — THE SWEEP.** Read the sheet, file the unfiled `New` rows as tickets, link
+   duplicates to existing numbers, post the field evidence onto the tickets, then resolve every
+   `🟡 PATCHED - RETEST` row by what the tester wrote in Test Status:
+
+   | Test Status | Meaning | Action |
+   |---|---|---|
+   | `Pass` | fix confirmed | close in gitea, move the row to CLOSED |
+   | `Fail` + detail | the fix did not hold | `🔴 FAILED RETEST`, reopen in gitea, raise to ≥P2, post their evidence |
+   | `Fail`, no detail | cannot act yet | `🟠 NEED INFO` with ONE discriminating question |
+   | blank | nobody tested it | leave `🟡`, roll to the next session |
+
+   ⚠ **A Pass or Fail with no BUILD NUMBER is uninterpretable** — a Pass on an older build cannot
+   verify a fix that shipped later. Before treating a `Fail` as a regression, establish that the
+   tested build actually contained the fix; that ambiguity is why #27 and #38 sat at `NEED INFO`
+   (asking for the boot-screen build) rather than going straight to `🔴`. Stamp "shipped in build
+   NNN" into every `🟡` Dev Comment so the answer is checkable later.
+3. Reconciling ~50 tickets against their threads is a fan-out job — one agent per batch of ~7,
+   returning `{num, dev_status, priority, dev_comment}`.
+
+## Access
+
+- **Read** — the sheet is public, so the CSV export works with no auth:
+  `https://docs.google.com/spreadsheets/d/<ID>/export?format=csv&gid=0` (307-redirects to a
+  `googleusercontent.com` host; follow it). The Claude **Google Drive connector cannot see it** —
+  that connector is scoped to files it created itself, and it has no cell-write capability for any
+  file, so sharing the sheet to the account does not help.
+- **Write** — a Google Apps Script web app bound to the sheet, called with `curl -sL -d` (never
+  `-X POST`). Actions: `ping`, `tabs`, `get`, `set`, `append`, `note`, `width`, `height`,
+  `autofit`, `format`. Extending it requires re-pasting the script AND
+  **Deploy → Manage deployments → pencil → Version: New version** — clicking Deploy alone keeps
+  the old code live on the same URL. Treat further script edits as expensive: the operator has
+  said the redeploy loop is not worth repeating for cosmetics.

+## 34. CHANGE DETECTION AGAINST A SHARED MULTI-WRITER SCRATCH: previousModeMask (#155, 2026-08-14)
+The engine ModeManager keeps ONE previousModeMask cell, overwritten by EVERY
+Add/Remove/ReplaceModeMask call.  Any consumer computing `changed = current ^
+manager->GetPreviousModeMask()` only sees the delta of the LAST write -- fine
+while exactly one writer touches the mode per frame, silently lossy the moment
+a second writer appears.  The authentic panic-arm chatter (the no-hysteresis
+eject evaluator flapping ModeEject per frame) made the gauge renderer's page
+XOR permanently blind to SetPresetMode's page bits: MFD page EXITS died while
+the PANIC lamp flickered (entries survived via !alreadyActivatedFlag; the
+always-active radar/score/coolant never consult the XOR -- the field's exact
+alive/dead split).  The renderer ALREADY OWNED a correctly-maintained
+previousModeMask member; reading the manager's scratch instead looks like
+lineage drift.
+**Rules:** (1) a change-detector must own its OWN baseline snapshot, sampled
+and advanced at ITS consumption rate -- never a shared scratch another writer
+can stomp between samples.  (2) When an authentic high-frequency toggler
+exists (chatter, flap, blink), audit every `GetPreviousModeMask`-shaped read
+it can starve (LAMP.cpp's read survives because lamp flicker IS the intended
+output).  (3) The live-human receipt loop cracked what two headless rigs
+could not: the injection path was clean, so the defect HAD to be presentation
+-- receipts proving delivery while the screen disagrees convict the renderer.
+
+## 35. THE SPLIT ALARM/INT CELL DISPATCHES STALE ON PREAMBLE TRANSITIONS (#102, 2026-08-14)
+
+In the binary, a gait SM's "state variable" and its AlarmIndicator LEVEL are
+ONE cell (`+0x3b0` == `legStateAlarm.level`, `+0x728` == body's) -- the switch
+reads it LIVE, so a preamble transition (the wind-down gate cutting 6-9 ->
+Standing, a death latch binding 0x1c-0x1f) dispatches its NEW state the same
+frame: with a reverse demand held, the gate frame falls straight into case 0
+-> SetLegAnimation(0x10), which REBINDS AND REWINDS the clip -- a parked pose
+structurally cannot linger.  The recon split the cell into an alarm + a
+mirror int synced once at function top; every mid-preamble SetLevel left the
+switch dispatching the STALE pre-transition case for one frame -- and any
+read of the mirror between preamble steps (the gate's own state test after a
+same-frame death latch) judged a dead value.
+**Rules:** (1) when a recon splits a binary cell into alarm + mirror, RE-SYNC
+the mirror after EVERY preamble step that can write the alarm, not just at
+entry -- or read the alarm directly at each decision.  (2) The binary's
+same-frame fallthrough semantics (gate -> case 0 -> rebind -> advance) are
+part of the state machine's correctness, not an optimization: the one-frame
+stale dispatch is exactly one frame of "no exit condition tested" -- the
+#102 class.  (3) Sibling of gotcha 30 (one cell, many port stores) and the
+namedClip aliasing class -- grep for `= (int)` alarm syncs when auditing any
+split-cell machine.
+
+## 36. AN INVENTED WRITE INSIDE A FAITHFUL TRANSCRIPTION: descriptor-as-authority (#125, 2026-08-14)
+
+The MechDeathHandler tick was transcribed with one line the binary does not
+have: `zone->ApplyDamageGraphicState(d->graphicState)` -- the effect
+DESCRIPTOR (a lookup result) written back into the zone's graphic state (the
+authoritative cell).  The raw @0042aa2c (part_003.c:10963-93) uses the
+descriptor ONLY to pick an effect resource; the gstate writers are the
+cascade, replication, and Reset.  With the pick hardcoded to Destroyed(1),
+the invented write STOMPED every cascade child's authored Gone(2) back to 1
+in the same tick, master-side, before the record shipped -- so the wire
+itself carried the corruption and no peer could ever render the authored
+state.  An added write is worse than a stub: a stub leaves the authentic
+writers alone; an invention actively fights them, and it fights them on
+every node that runs the transcription.
+**Rules:** (1) in a transcription, every WRITE to authoritative state must
+have a byte-level citation -- effects/lookups reading state is safe, state
+consuming a lookup result is the red flag; (2) convict with a before/after
+receipt AROUND the suspect pass (the [BTrender] seg lines caught gstate 2
+becoming 1 between two remakes -- one receipt, whole conviction); (3) when a
+lookup table carries entries UNREACHABLE by its primary key (the lvl=-1
+gs=1/gs=2 terminals), those entries name the binary's OTHER selector -- find
+it before assuming the reachable subset is the whole contract.

+# Radar/Map Display Drift Audit — binary vs port vs content (2026-08-14)
+
+**What this is:** the AI-facing ledger of the radar/map subsystem audit (3-agent,
+full reports preserved at `scratchpad/night17/radar_audit_{bin,port,content}.txt`;
+~800k tokens of reads). Trigger: #49 (arena walls missing from radar) + the field
+report "many map items aren't showing on radar, like map boundaries."
+Companion fix: the static world feed, commit `c2193e2` (#49 CLOSED, operator-verified).
+
+## The architecture, as the machine built it [T1 unless noted]
+
+- ONE radar picture for every map/mech: the 480×640 portrait `BTSEC1.PCX` +
+  `BTSEC1OV.PCX` baked art (tick ring + crosshair — **no range rings exist**),
+  with the live `map(` widget in the (366,367) scope rect at (58,229). There is
+  **no per-map radar art and no map page** — the ModeMapping bit is the
+  weapon-button CONFIG session, not cartography (aliased ModeNonConfig [T0]).
+- **Entity membership** (@004cbfa0, the interest feed): an entity reaches the
+  scope iff (a) a type-0x12 GaugeImageStream pip exists for its resourceID AND
+  (b) Mover-derived → moving list, else Terrain-GRAPH-derived → static list.
+  The derivation graph parents UnscalableTerrain (0x2A), CulturalIcon (0x5E)
+  and Landmark (0x56) onto Terrain [T0 TERRAIN.cpp:183, CULTURAL.cpp:27] even
+  though their C++ bases differ.
+- **Draw order** (@004c22c4): wedge → static pips → moving pips → name labels,
+  inside a stroke recorder (erase = replay last frame in bg color).
+- **DrawStatic** (@004c25b4): each in-capability static's pip drawn with the
+  entity's FULL transform — walls/buttes/hills/ridges/buildings/trees rendered
+  as world-rotated, metre-scaled staticColor(3) outlines. 110 authored GIMs
+  ship (wall1-3, aw01-05, ab*/ar*/bld*, buttea-e, hillg/dhillg 652-byte
+  contours, sr1e/n/s/w polar rails, tree, dish, …).
+- **DrawMoving** (@004c2788): every mover except the operator, color 7, target
+  boxed (+4px, hotbox color 1). NO self-blip; NO pipless fallback (every
+  shipped mech has a pip).
+- **DrawNames** (@004c28c4): ≤16 callsign labels (64×16 egg rasters via
+  playerBitmapIndex); the target's label BLINKS at frame rate.
+- **Zoom**: 6-step exponential, RadarRange = 250·2^level (250…8000 m scope
+  width), SLEWED smoothly; SCALE numeric shows it live. Capability radius =
+  RadarPercent × 4000 m — radar damage shrinks detection (#105/#121 pending).
+- **Wedge**: hardcoded π/8 half-angle (45° total); the config's "180" param
+  only sizes the DEAD shadow table. (Manual says "60° field of vision" —
+  print-vs-code drift, the code wins for 4.10 [T1 vs manual].)
+
+## Authenticity verdicts the port must respect
+
+1. **The pure map boundary was INVISIBLE on the shipped machine.** Every
+   outdoor map places one `wall10k` (collision solids only, ±4100 m ring —
+   no pip, no video model). Players saw a "boundary" only where visible
+   wall/ridge ENTITIES formed the perimeter (arena aw*, polar sr1* rails, rav
+   buttes). Do NOT invent a boundary rectangle. (ExistanceBox type-26 extents:
+   arena ±700, rav ±1000, others ±7000 — available if a design call ever
+   wants one.)
+2. **BuildRadarShadow (@004c228c) compiled EMPTY** — radar occlusion shading
+   was cut before ship. The port's empty body is faithful.
+3. **Authored pip omissions are design**: floors/sky, wall10k, overhead butte
+   tops (butteeu), walkways/banners, snow banks have NO pips on purpose.
+   Never force-draw them.
+4. **Missile pips are authored dead content**: lrm/srm/strk/nrk GIMs ship, but
+   Projectile/Missile are Entity-derived in the graph — they fail both class
+   tests and never listed on the machine either.
+5. **Landmark labels + DropZone blips: dormant/absent** (zero Landmark
+   instances; DropZones carry rid −1).
+
+## The #49 root cause + fix (2026-08-14, c2193e2)
+
+The port dropped the engine's per-entity interest feed and replaced it with
+`GaugeRenderer::RebuildEntityGrid` — which iterated DYNAMIC masters/replicants
+only. The 1008 statically-registered UnscalableTerrain instances (every wall,
+butte, hill, ridge, big building) never entered the static grid; DrawStatic
+(fully transcribed and working) had nothing to draw. Dynamic-registering
+CulturalIcon props (e.g. grass's 313 trees) were the only statics that ever
+showed. Fix: a third RebuildEntityGrid pass files non-dynamic Terrain-graph
+entities from `HostManager::AllEntityIterator`; pipless ones no-op at the pip
+lookup exactly as on the machine. Receipts: `[map-grid] worldStatics=` census +
+capped per-static `[map] static ent/cls/rid/pip/dsq` dump (BT_MAP_LOG).
+Benched grass (hill cls=42 rid=2190 pip=1 drawing + trees) and arena1
+(126 world statics, aw walls rid 1918/1915 drawing, unpipped props skipped);
+operator-verified visually on arena1.
+
+## Known port deviations (deliberate, inventoried)
+
+- Three visible-radius culls (DrawStatic/DrawMoving/DrawNames) drop contacts
+  between scope radius and capability radius instead of the binary's
+  draw-and-clip — justified by the shared gauge surface (out-of-port draws
+  land on neighbors). Revisit only with a real GraphicsView clip.
+- Cross-blip fallback for pipless movers (dev content insurance; dead in the
+  field — every shipped mech has a pip).
+- Dead-mover (state 2/9) radar drop: the wreck-blip removal. The binary's
+  uninteresting-notification presumably did the same [T4 — unverified whether
+  a pod wreck kept its blip].
+- Per-frame O(all-entities) rebuild vs the authentic event-driven feed —
+  acceptable at shipped populations; restoring the notify feed retires it.
+
+## Stale notes corrected by this audit
+
+- `mech.cpp` "SetTargetRange is stubbed" — FALSE since the zoom work
+  (btstubs.cpp body + the mapper slew); comment swept 2026-08-14.
+- `btl4rdr.cpp` header "Make has no exported caller" — stale; @004c1b4c IS in
+  the 2026-08-06 re-export.
+- `docs/GAUGE_COMPOSITE.md` row 24 "cross-blip stand-in" — stale; pips are the
+  live path since dd27238.
+
+## Open follow-ups
+
+- ERA QUESTION (for the group): what did the ARENA EDGE look like on the pod's
+  scope — just the wall outlines, or anything more? (Guards against inventing
+  a boundary ring; the code says wall outlines only.)
+- #105/#121: RadarPercent is pinned 1.0 until sensor damage lands — the
+  capability-shrink lane is authored and waiting.
+- The 45°-wedge vs the manual's "60° field of vision" — flag to testers
+  comparing against memory; the 4.10 code hardcodes π/8·2.
+- Overlay-plane compositing into the dev sec cell (SECTOR/SCALE readouts) —
+  existing polish item, unchanged.

+(3-agent: binary/input/content + bench matrix night18/gaithang_bench.sh) found the port
+was missing the machine's whole HARD-BRAKE system: master perf @0x4aa158-0x4aa365 swaps
+the gait slew to the model's SuperStopAcceleration when a forward cycle meets a reverse
+demand (+0x3f4 "airborneSelect" = the BRAKE latch, another jump-jet-family misread;
+0x5bc "airborneCycleRate" = the brake rate) + gyro random-sign lurch on engage + 0.4s
+vertical judder above walk speed (gyroRumbleTimer@0x5c4). Content: heavies brake harder
+than they accelerate (10->20), OWENS brakes at HALF (50->25) -- the sprinter's long
+coast is authored; the pod communicated it through the cab shake, the port coasted
+SILENTLY = the felt hang. PORTED (mech4 drive block, [brake] receipts) + the
+same-frame re-dispatch parity fix (gotcha 35: split alarm/int cell dispatched stale on
+gate/death-latch frames; both channels re-synced). Bench: ALT sign-flip at full run =
+clean chain into reverse w/ brake receipts; held-brake-key = clean authored stand, zero
+brake (authentic), twist arms trn from the park (the rescue). REVERSE INPUT TRUTH: red
+button 0x3F/LALT sign-flip, demand = -runSpeed*throttle (NO fwdScale); brake keys can
+NEVER reverse (throttle [0,1] like the pod lever) -> HANDOUT education line. Side-find:
+hardware-RIO cab reverse is DEAD (AddOrErase stubs; open-questions row). KEYSIM bench
+hooks added (BT_KEYSIM/_REV/_TURN). 674 worktree forensic pending -> ticket close.
+SUNDAY build now carries: turn rates + #155 banks + #49 radar + #102 brake system.
+NEXT: #125 first-destroyed-zone edge.
+NIGHT18 addendum: 674 forensic RESOLVED without a repro run -- the 674 build boots the
+GLASS profile by default (log: '[boot] platform profile: GLASS'), so PadRIO owned
+reverseThrust and the BT_FORCE_FLIP negative-throttle path was stomped (rev=0 all run);
+i.e. reverse at 674 was exclusively LALT on every rig.  The statue itself = the trn
+turn-stop MID-PIVOT park (authentic, pod-invisible: no external self-view existed);
+bench D reproduced it at trn legFrm=10 + twist rescue.  Peer brake-rate select restored
+in the replicant motion path (IntegrateMotion:298 is dead code -- Simulate bypassed).
+Final build: 20 benign LNK2019s exact.
+NIGHT18 (cont): #125 FIXED + 2-node benched.  Root pair: (1) the Tick transcription
+carried an INVENTED write -- ApplyDamageGraphicState(descriptor) -- the raw @0042aa2c
+(part_003.c:10963-93) only PICKS an effect (level flag -> ForLevel; gstate flag ->
+ForGraphicState(CURRENT gstate), overwriting); the hardcoded-Destroyed pick stomped
+every cascade child's authored Gone(2) -> 1 master-side pre-send: the gun pod NEVER
+dropped off a killed arm on any node (gotcha 36).  (2) the mesh swap was descriptor-
+gated; now per-zone gstate caches fire ONE coalesced RemakeEntity on any edge (the
+binary re-picked meshes from gstate per frame).  Restored authored story: killed gun
+= wrecked thrdrgun mesh hangs; killed arm = wrecked thrdrarm (exterior skel) + pod
+VANISHES -- peers see all of it on the FIRST beat ([zone-repl] dz_rgun gstate 0->2 +
+peer remake, mp_zone125.sh fix/legacy receipts).  Heal edges fire no effects (Exists
+suppression; binary Reset writes raw).  Respawn regression clean (0 heal puffs).
+SUNDAY build now: turn rates + #155 banks + #49 radar + #102 brake + #125 zone edge.
+Handout candidates: 'arms now visibly wreck + pods drop off on everyone's screen'.
