STRAFE: draw the heat field, real bullet danger, corrected ring comment
Three defects the owner hit as "no heat tiles anymore" under TR_MOVEMENT=strafe. 1. The strafe overlay drew ONLY the tiles on its strafe line, so the computed heat field was essentially invisible. It now draws the WHOLE field exactly as TFIL does (every non-zero tile, yellow->orange->red ramp by field max, integer value label) behind the same debugGraphics flag, with TR_STRAFE_HEAT_GRID=0 to hide it. The strafe overlays draw on top, unchanged. 2. STRAFE carried the SHIPPED bullet constants (core 10 / aura 5), so a bullet's own heat sat exactly ON PathDangerThreshold (10.0) and a bullet was never dangerous on its own in this mover; it only ever bit through its corridor. Defaults are now the retune's 20/10, exposed as TR_STRAFE_BULLET_CORE / TR_STRAFE_BULLET_AURA. 3. The ring mover's header documented CorridorHeat 5.0 / WallHotness 10.0 while the code has always been 10.0 / 15.0. A job read the comment and handed out sub-threshold heat values, which emptied the field. The comment now states the real values and their actual behaviour; no code values changed. Also sets strafe's heat defaults to the retune shape (bullet 20/10, corridor 10, wall 15/5, pillar 0), documented with the reason. Gate A re-run (j110, offline DrussGT fixture, measure_strafe_gates.nim): corrected DEFAULT : 24.6% of picks with ZERO safe tile, mean 11.17 safe j108 shipped field: 63.4% / 3.70 (reproduced exactly) j108 ring retune : 8.1% / 18.41 (reproduced exactly) bullet isolated : 11.4% / 17.07 The corrected default beats the shipped field but is WORSE than j108's retune row: the bullet retune alone costs 8.1 -> 11.4, the corridor/wall retune accounts for the rest. That is the deliberate price of making a bullet dangerous. Guards green: test_env_report 24 PASS, test_tfil_commit_env 30 PASS (shipped TFIL default untouched, byte-for-byte), test_tfil_ring_weights 24 PASS. The three new knobs are registered in the boot env report so the tree-scan guard stays clean. |

ModularBot: [result] round/battle outcome log lines (TR_RESULT_LOG, default on)
One greppable '[result]' line per round plus one at battle end, stdout only: [result] round 3/7 WE WON (enemy destroyed) | us 42.1 energy, them 0.0, 812 ticks | rounds won 3/7 [result] battle END: rounds won 4/7 Outcome is authoritative from RoundEndedEventForBot.results.rank (1 = winner); death observations (our onDeath, enemy onBotDeath) and onWonRound refine it into WE WON (enemy destroyed) / WE DIED (killed) / BOTH DIED (score decided) / TIMEOUT (score decided). Our own death is reported the instant it happens. TR_RESULT_LOG registers in the boot env report; default on, only explicit off-values disable it. No behaviour change - logging/state only. |

STRAFE movement: body pinned perpendicular to the threat, reversals by sign flip
New engine movements/strafe.nim, selected by TR_MOVEMENT=strafe (default stays tfil, byte-identical — test_tfil_commit_env.nim's 30 checks still pass). Design (the owner's): - AXIS = incoming bullet's direction when a bullet is in flight, else the perpendicular of the enemy bearing. The body heading is kept inside a band (TR_STRAFE_BAND, default 20 deg) around the perpendicular LINE; it turns only when outside the band, and never turns to face a movement target. - Candidate tiles on the perpendicular line through our position, both forward and backward, within TR_STRAFE_REACH px, with a perpendicular jitter of +/- TR_STRAFE_SPREAD tiles. A tile is acceptable when its path max heat is <= PathDangerThreshold, the SAME safety rule TFIL uses. - Move by SIGN only: setForward(+/-MaxSpeed>). Dwell is re-picked after a random number of ticks in [TR_STRAFE_DWELL_MIN, TR_STRAFE_DWELL_MAX], on arrival, or on a serious threat spike. - Heat machinery is REUSED from the shipped mover, not re-implemented: the exported heatDecay()/bulletMagScale() (j105 time-indexed model) and the PillarHotness/PillarRadiance globals (j106 pillar-free default). The heat shape is overridable via TR_STRAFE_CORRIDOR_HEAT/WALL_HOTNESS/WALL_RADIANCE (defaults = the shipped TFIL field). - GUI overlay: strafe line, threat axis, candidate tiles (safe/unsafe), chosen target, sign-coloured movement ray, and the heading band. Gates (offline, recorded DrussGT fixture, 20026 ticks): - A TILE AVAILABILITY: shipped heat field -> a safe tile exists on only 36.6% of picks (63.4% fall back to the least-hot tile); the ring retune (corridor 5, wall 10/5) raises it to 91.9%. - B PREDICTABILITY: reversal-interval entropy 5.84 bits vs TFIL 5.09; direction entropy 1.00 both; long-lag autocorrelation ~0 for both (no periodic component). Fewer reversals (710 vs 1453) and more full-speed ticks. measurements: common_libs/tests/measure_strafe_gates.nim Also registers TR_STRAFE_* in the boot env report (ModularBot_garage/src/ env_report.nim) and wires the engine into ModularBot.nim (hold -> strafe, ram trigger -> rammer). |

TFIL: remove the virtual centre pillar from the shipped default; register j102 env reads
The default mover painted a 30/10 radiance blob on the arena centre even though the arena has NO physical pillar there, creating a 4x4 tile (144x144 px) exclusion zone over open centre floor. Set PillarHotness/PillarRadiance to 0/0 in the shipped default (matching the ring variant) and add TR_TFIL_PILLAR_ON=1 to restore the old 30/10 field for A/B without a rebuild; registered in env_report. Because the shipped default legitimately changed, the default-path parity golden (fixtures/tfil_commit_default.golden) was regenerated from the NEW default, with an explicit 'deliberate default change' note in the test so a future failure is treated as a real regression. Also register the three env reads job j102 added in common_libs/bitbrain (TR_BITBRAIN_MODE / _DECAY_EVERY / _DECAY_SHIFT), which the env-report guard was failing on. Verification: test_env_report all green; test_tfil_commit_env 30/30. |

TFIL: time-indexed bullet heat (TR_TFIL_HEAT_TIME, DEFAULT OFF)
Make danger a function of time-to-arrival instead of flat distance. Bullet
core/aura/corridor heat becomes magnitude(power) * decay(dt), dt = along/speed:
* decay(dt) = exp(-dt/tau) is a function of TIME; a fixed tau projects a
pixel reach of speed*tau, so fast/weak bullets get a longer slope and slow
ones a shorter one — derived from speed = 20 - 3*power, not hand-tuned.
tau = TR_TFIL_HEAT_TAU.
* magnitude(power) scales the near-end heat with power from DAMAGE
(calcBulletDamage = 4p, linear in p; SCORE_PER_BULLET_DAMAGE = 1.0). Hit
probability is FLAT across power (docs/env_reference.md), so risk does not
justify power scaling — the cost of the hit does. Floored at 1.0 so a weak
bullet's near end is never less dangerous than the flat model.
Gain = TR_TFIL_HEAT_POWER_GAIN.
Every source is already f(dt), so the time-indexed planner (evaluate a cell at
the tick the bot would ARRIVE, i.e. heatDecay(dt - arrivalDelay)) is a one-line
change. It is intentionally NOT implemented here.
Default path is byte-identical: with TR_TFIL_HEAT_TIME unset both factors are
exactly 1.0 (IEEE x*1.0 is exact), and the committed golden replay in
common_libs/tests/test_tfil_commit_env.nim (20,026 ticks) still passes
byte-for-byte against the pre-change mover. The debug corridor outline is also
drawn only to the model's reach when enabled, so the GUI shows the shortening.
Offline field measurement (common_libs/tests/measure_tfil_heat_time.nim,
46,054 fixture ticks, tau=9/gain=1): corridor reach drops from 443px
wall-to-wall to 143px mean (32% retained); fraction of tiles > 10 goes
0.61 -> 0.57; largest contiguous safe region 118 -> 140 tiles; mean
distance-to-nearest-safe-tile 49 -> 42px. Saturation stays high because wall
radiance + pillar alone are 44% of tiles over threshold and are untouched.
Registers the three knobs in env_report (report + known-name set).

BitBrain: TR_BITBRAIN_GAINS env knob (candidate set + fixed-gain degenerate)
Task A of campaign phase 2: the lead-gain candidate set is now pure env, so the live arms need no recompile. - common_libs/guns/bitbrain_gun.nim: BB_GAINS_ENV (TR_BITBRAIN_GAINS); the candidate list is parsed once at gun construction into a dynamic seq, so the hit counts/hit rates are sized to it. Unset/unparsable -> the shipped BB_CAND set [0,0.25,0.5,0.75,1.0] (byte-identical behaviour). Exactly ONE candidate degenerates to a FIXED gain applied from the first shot (learning bypassed), still gated to the long bands. parseGains clamps to [0,8], de-dupes and sorts so the argmax tie rule is unchanged. The [bb] line now prints the APPLIED gain AND the resulting angular shift, so a run's correction is auditable from stdout. - ModularBot_garage/src/env_report.nim: emit TR_BITBRAIN_GAINS (resolved candidate set) and add BB_GAINS_ENV to the known-name list. - tools/ab/arms_leadgain.txt: the 6-arm phase-2 sweep definition. |

BitBrain gun (id 16): Pattern-relative ADE+SBC aim corrector, default off
Wire the verified common_libs/bitbrain ADE+SBC library into ModularBot as a
fine-grained angular corrector on top of Pattern's prediction, the shape the
offline gate test measured (argmax readout over N correction classes).
- common_libs/guns/bitbrain_gun.nim: new gun. Input = the existing TMHorizon
53 bits (tmhBaseBits + tmhLits); output = argmax class centre over
+-TR_BITBRAIN_RANGE, applied by rotating the Pattern point around the shooter
exactly as tmhApplyShift does. Label = the +h-tick fact from TmHorizonGun's
own observation ring (never across a round). Prequential (defer + resolve).
AD layer synthesised online for our binary inputs (center=0): heuristic
cold-start thresholds + running-histogram ~1% percentile init + the library's
adaptThresholds. Memory modes perRound (default, measured best) / retained /
decay (periodic partial SBC wipe). Lazy network build + local RNG, so the
default path builds nothing and consumes no global randomness.
- tm_horizon.nim: export tmhUpdateHistory and add tmhObservedAt (label seam).
- selector.nim: register BITBRAIN at rack id 16, default rmOff, in the SAME

TFIL: env-gated commitment arms (tile-replan cancel is a bug)
The tile-change replan cancels the 15-tick movement commitment whenever OUR
tile changes. With GridSize=36 and speed up to 8 px/tick that is every ~5
ticks, so the commitment is cancelled by the motion it commands (measured:
96.9% of picks were tile-change replans, 33.8% of picks reversed direction).
Adds four env knobs, every default reproducing the shipped mover
byte-for-byte:
TR_TFIL_TILE_REPLAN self (default) | off | enemy
TR_TFIL_COMMIT_TICKS 15 (default)
TR_TFIL_NO_REV 0 (default)
TR_TFIL_COMMIT_LOG off (default, JSONL per-tick diagnostics)
- `off` honours the commitment; the danger replan stays the safety valve.
- `enemy` keys the cancel to the TARGET's tile displacement (the intent the
original comment claimed).
- `TR_TFIL_NO_REV` down-weights (never filters) tiles >90 deg from the travel
direction; the pool can never be emptied.
Default-path parity is guarded by test_tfil_commit_env.nim, which replays
tools/fixtures/tr_drussgt_vs_modularbot.jsonl and diffs every move command
against a golden generated from the pre-change build (git archive

Env report Part 2: warn on misnamed env vars (unknown + compile-time defines)
The boot report printed the raw env and the resolved values, but it never
told the user when a name was WRONG - which is the failure mode that cost
real time: `TMH_NSTATES` was exported as an env var although it is a
compile-time `{.intdefine.}` (`guns/tm_horizon.nim:102`), so the export was
a silent no-op. Add the two warning paths, both boot-only and stdout:
* unknown TR_*/GUN_* names are named explicitly. The known set is built
from the modules' exported env-name constants; the remaining inline
reads are listed once, and common_libs/tests/test_env_report.nim scans
the tree and fails if a name read anywhere is missing.
* any `{.intdefine.}`/`{.strdefine.}`/`{.booldefine.}` symbol present as
an env var is flagged, with the real runtime equivalent when one exists
(`TMH_NSTATES` -> `TR_TMHORIZON_NSTATES`) and an explicit "does not
exist - this knob is compile-time only" when it does not. The map is
derived by grepping the tree; the same test re-greps and fails on drift.
Warnings are emitted only when the env is dirty, so a correct run keeps the
documented A/B/build shape. TR_ENV_REPORT=0 still suppresses everything.
test_env_report.nim: 25 checks (known set, pure helpers, tree literal scan,
tree define scan). All 15 existing guard tests keep their exact counts.

Boot-time env report + fix the env reference
The bot is spawned by the server/GUI, so it inherits the SERVER's environment. The user could not tell whether their exports reached the bot, so print a one-shot greppable report at boot: grep '^\[env\]' /tmp/modularbot_stdout.log Section A prints every TR_*/GUN_* this process actually received, the count vs the total env size, a loud warning when nothing matched, and the process identity (pid/ppid, cwd, self command line, and the PARENT command line) so the spawn trap is obvious. Section B prints the resolved effective value of every documented knob with its source (env|default), including clamps and the rack's empty-set fallback. Build identity (NimVersion, compile date/time, binary path/size/mtime) pins the exact artifact. Suppress with TR_ENV_REPORT=0. docs/env_reference.md: add the missing GUN_SHOTLOG_PATH, GUN_SELECTOR_MINOBS/FLOOR/POOL/RANK/SHRINK/SEED, TR_ENV_REPORT and -d:TM_NCLAUSES; record the measured TR_TMHORIZON_WINDOW verdict; and add a prominent 'Did my env vars actually reach the bot?' section with the boot report, the /proc/PID/environ no-code check, the correct GUI launch recipe, and how to prove the trap deliberately. |

Energy economy: the cliff becomes a SLOPE, plus a finishing cap. 11% less energy.
The user's request: "when our bot is low OR enemy is low, it is useless to use high power instead low fast bullets have more chances to finish the enemy. Let's do a math slope: starting from some health down, the power goes down with it." 1. ENERGY SLOPE (`TR_POWER_ENERGY_*`), replacing the old hard step at 50 energy: cap = ENERGY_MAX at/above ENERGY_HI, ENERGY_MIN at/below ENERGY_LO, LINEAR in power between, clamped. Defaults HI=80 LO=20 MIN=0.5 MAX=3.0, so no cap >=80, 0.5 at <=20, and e.g. E=65 -> 2.375, E=50 -> 1.75, E=35 -> 1.125. Rationale: bullet speed is 20-3p, so lower power = FASTER bullet (less lead error, higher hit chance), fires more often (10+2p) and drains slower (p/shot). E[dE] = p(3P-1) => break-even hit probability is 1/3 INDEPENDENT of power, and our measured rates are 5-27%, far below it. 2. FINISHING CAP (`TR_POWER_FINISH_KILL`, default ON): cap power at the SMALLEST bullet that still removes the enemy's remaining energy - `E<=4 -> p=E/4` (min 0.1), `4<E<=16 -> p=(E+2)/6`, `E>16 -> no cap`. Rationale, and it makes the user's instinct stronger than a heuristic: server 1.3.1 caps the damage SCORE at the energy ACTUALLY REMOVED, so overkill is WASTED damage AND ~6x the energy for ZERO extra score. Damage is 4p (p<=1) / 6p-2 (p>1). Both are min-composed with the existing far/below-average caps, may only LOWER power (exhaustively tested), and are exempt while ramming. `TR_POWER_POLICY=0` still returns the uncapped control exactly. MEASURED ENERGY SAVING (offline replay of the DrussGT fixtures, 28,797 ticks): arm shots energy meanP E/1k ticks vs cliff control(uncapped) 1913 4646 2.43 161.4 -90.2% cliff (today) 2363 2443 1.03 84.8 0.0% slope 2404 2178 0.91 75.6 ** 10.9% LESS ** slope+finish 2404 2167 0.90 75.3 ** 11.3% LESS ** So the slope spends ~11% less energy than the cliff AND fires slightly MORE shots (2404 vs 2363) - both directions at once. HONEST NOTE on the finishing rule's reach here: ticks where the enemy is low (0 < E <= 16) are only 2252/28797 = 7.8% of these fixtures, so finishing adds just ~11 energy of saving against DrussGT. It matters in CLOSER fights, not this one. Verification: test_power_policy 58 (was 26) in BOTH the default and TR_POWER_POLICY=0 control arms - slope at E=100/80/65/50/35/20/5, powerToKill across E=0.1..100, the inverse-cover property for E<=16, monotonicity, ram exemption, and an exhaustive sweep proving power <= preference. Guards: test_gun_harness 39, test_vbullet_metric 11, test_power_selection 3, test_adaptive_radar 41, test_tfil_ring_weights 24, test_ram_decision 40, test_rack_membership 48, test_selector_tiebreak 19, test_tm_pattern_registration 20, test_vbullet_admit_gate 12. acceptance 12/12 PASS. ModularBot compiles release. Adds `common_libs/tests/measure_power_policy.nim` (the energy/histogram tool) and updates docs/env_reference.md for the new `energySlope|finishKill` log reasons. NOT MEASURED: the battle/hit-rate effect. The offline figures use the fixture shooter's energy as a proxy, open-loop; the RELATIVE saving is the meaningful part. |

TM horizon: retain learning ACROSS ROUNDS, reset only when the ENEMY changes
The user's requirement: "every battle i means from round 1 to round end-battle, so retain all learning until the enemy change." What was built wiped the Tsetlin machines EVERY ROUND, in two places (`onRoundStarted` and the gun's own tick-regression self-reset), so in a 7-round battle each round started cold, trained ~360 samples and threw them away - discarding most of its one chance to do what was asked: overfit the current enemy over the whole battle. THE FIX - two kinds of state, two triggers: - **`resetRoundState` (per ROUND)**: the observation ring, pending/deferred labels, the bullet proxy, motion history, per-tick caches, `roundStartTrained`. These MUST clear every round, because bots teleport back to the starting corners between rounds - an old position would build a garbage label. (That exact class of bug shipped 36-58% wrong labels in the old gun.) - **`resetLearning` (per BATTLE / per ENEMY)**: both Tsetlin machines, `trained`, `sideCorrect/sideTotal`, all histograms, the magnitude median, `pendingDropped`, `observedTargetId`. These now SURVIVE round boundaries. Triggers for the machine wipe: `onGameStarted` (primary) plus a redundant `roundNumber <= 1` fallback in `onRoundStarted`; and a TARGET CHANGE (`targetChanged`, knob `TR_TMHORIZON_RESET_ON_TARGET` default on - a no-op in 1v1, fires on melee target switches; first acquisition never wipes). The tick-regression self-reset now clears ONLY per-round state. Still NO cross-battle persistence: grep for file I/O in the gun finds none. PROOF IT WORKS (live 2-round battle, `TR_RACK_PATTERN=off TR_RACK_TMHORIZON=both`): [tmh-reset] reason=game_start trained_was=0 [tmh-reset] reason=round1 trained_was=0 ...exactly TWO reset lines in the whole battle, both at battle start, and NONE at the round-2 boundary. And the per-round summaries: [tmh-round] trained=1249 thisRound=1249 ... sideAcc=711/1177 (60.4%) [tmh-round] trained=2226 thisRound=977 ... sideAcc=1361/2154 (63.2%) `trained` CLIMBED 1249 -> 2226 across the boundary, and side accuracy rose 60.4% -> 63.2% in round 2 (one battle - suggestive, not proof). Unit tests: `test_tm_horizon` 79 (was 54), including "trained SURVIVES the boundary", "clause states SURVIVE", "trained climbs round1->round2", "game-start wipes and all clauses end Exclude", "different enemy wipes / same enemy does not / knob-off does not", and crucially "a label CANNOT be built across a round boundary" (ringValidCount==0, ringHas(oldTick)==false, pendingCount==0) - the single most dangerous interaction of this change. Guards: test_tm_horizon 79, test_rack_membership 48, test_gun_harness 39, test_vbullet_metric 11, test_power_selection 3, test_adaptive_radar 41, test_tfil_ring_weights 24, test_power_policy 26, test_ram_decision 40, test_selector_tiebreak 19, test_tm_pattern_registration 20, test_vbullet_admit_gate 12, test_tm_diag 48, test_tm_automata_diag 55, test_tm_clause_shape 66. acceptance_offline_vs_online 12/12 VERDICT PASS. Shipped rack unchanged: DefaultRackMembership is still Pattern-only, TMHORIZON off. Residual (pre-existing, out of scope, stated): the internal base `PatternMatcherGun` has a rolling move-history buffer that is NOT cleared at round boundaries - it never was, and the SHIPPED Pattern gun carries history across rounds too. It cannot affect label correctness (labels come from `g.ring`), only base-prediction quality in a round's first ticks. |

Ram: finisher-only by default, and the bullet-rain abort now measures real energy
Follows the diagnosis that proactive straight-line ramming CANNOT work: both bots have MAX_SPEED=8, so a pursuit cannot catch an evading equal-speed opponent. Measured over 49 rounds per arm, opportunity -> contact was **0/6** (base), 0/40 (ring), 0/12 (ringhot). The only proactive conversion in the whole corpus came from a FINISHER, and only because a <20-energy DrussGT stops fleeing (that episode closed at 6-8 px/tick). Opportunity episodes never got below ~80px; one ran the full 60-tick duration cap and closed only 198->171px; a perfectly aligned full-speed one closed 195->114px then plateaued. CHANGES - **Finisher-only default.** `finisher` (<20 energy, dist<300, we are healthier) and the rare `desperation` (both <5, dist<150) are kept; `opportunity` and the speculative `plan` are OFF. Both are env-reenableable with no rebuild: `TR_RAM_OPPORTUNITY=1` (tune via TR_RAM_OPP_DIST/MARGIN) and `TR_RAM_PLAN=1`. Justification: it removes 100+ non-converting episodes per fixture at zero measured loss (oldram vs base was p=0.69, damage 279 vs 284, survival 17/49 vs 16/49) - and each of those episodes spent up to 60 ticks driving STRAIGHT at the enemy, abandoning the mover's dodging and disrupting aim. - **`desperation` KEPT** deliberately: it is cheap and rare, fires only when both bots are nearly dead at short range (a coin-flip where 0.6 contact can decide it), and it is not the refuted straight-line pursuit. - **THE BULLET-RAIN ABORT WAS DEAD CODE AND IS NOW FIXED.** `onHitByBullet` accumulated raw bullet FIREPOWER while `TR_RAM_ABORT_DMG = 0.5` was documented as a DAMAGE rate - so the bar was implicitly "sum of power > 7.5 over 15 turns" and the maximum rate ever observed was 0.27. It now accumulates REAL ENERGY via a `bulletDamage(power)` helper matching the server's `4p` / `6p-2` formula, and `TR_RAM_ABORT_DMG` defaults to **2.0 energy/turn** (~30 HP over 15 turns): "abort an in-progress ram if we take > 2.0 energy per turn". Same effective bar for normal firepower, and it can now actually fire - the live run reports `dmgRate=1.07/turn` where the old units said 0.27. - **`ramStuckTicks` REMOVED.** It required `dist < 5px`; contact occurs at ~36px (two 18px radii) and position rewind prevents getting closer, so it could never increment. Only the 60-tick duration cap can now self-end a ram. LIVENESS (measured, default config, vs a charging Java RamFire, 3 rounds): default -> `[ram] ON reason=finisher` x3, `reason=opportunity` x0 TR_RAM_OPPORTUNITY=1 -> `reason=opportunity` x4, `reason=finisher` x2 So the opportunity states DID occur and are suppressed by the new default - the removal is real, not an arm that never fires. A line also read `[ram] OFF reason=duration dmgRate=1.07/turn`, confirming the new energy units. Adds docs/ramming_negative_result.md (70 lines) recording the question, the five diagnostic answers, the geometric reason, the finisher exception, the two dead code paths, and an explicit "do not re-attempt a proactive straight-line ram; if point-blank forcing is ever wanted it is an INTERCEPTION/cornering movement problem" note - the same pattern that stopped the corpse bug recurring. Guards: test_ram_decision 40 (was 28), test_gun_harness 39, test_vbullet_metric 11, test_power_selection 3, test_adaptive_radar 41, test_tfil_ring_weights 24, test_power_policy 26, test_rack_membership 48, test_selector_tiebreak 19, test_tm_pattern_registration 20, test_vbullet_admit_gate 12, acceptance_offline_vs_online 12/12. ModularBot compiles. Honest note: the abort-threshold fix is a real (tiny) behaviour change, NOT measured-neutral - it only bites while a finisher ram is under sustained fire, which is exactly the user's stated wish. The finisher-only removal itself is measured-neutral per the given A/B. |

TM radial gun: registered (default OFF) + label-bias fix that removes the bias but
retracts its own earlier learning claim === TASK 1: REGISTERED AS GUN 14, DEFAULT `off` === The radial TM gun is now a first-class rack member (`TMPATTERN`, id 14), forceable alone with `TR_RACK_TMPATTERN=both` plus every other `TR_RACK_*=off`. DEFAULT IS `off`, and the justification matters: `both` would let it compete for selection AND (because the shared VirtualTracker ring is order-sensitive) shift every other gun's learning order, so it CANNOT leave the default path unchanged. With `off` its predict and spawnBullets are additionally GATED on rack admission (the only gun wired that way), so the shipped default never spawns it at all: zero cost, zero ring perturbation. Live proof: 1-round battle with only TMPATTERN racked -> `gun 14 (TMPattern): vShots=400 selected=104 other-gun selections=0`. Default-path-unchanged proof: parity checks that the 15-gun default bestGun/ selectGun equals the old 14-gun rack RNG-draw-for-RNG-draw, that gun 14 is never selected by default, and acceptance 12/12. Cost: 0.36 ms/tick (predict 0.30 + onResult 0.05) ~= 3% of the 13.16 ms budget. Tsetlin in the same harness is 1.62 ms/tick, so the new gun is ~4.5x cheaper. === TASK 2: THE LABEL-BIAS FIX - AND A RETRACTION === Root cause confirmed: under bmPoint a SHORT radial correction resolves the virtual bullet BEFORE the base arrival tick, so the label was dropped (labelMisses). Fix: defer the label in a pending queue and flush it once the arrival tick is recorded; labels still come from the BASE arrival tick. labelMisses 4,281,695 -> 0 training samples 1,071,824 -> 5,345,847 (x5) radial head acc 48.8% -> 57.0% (shuffled control 20.0%) bmPoint hit rate 9.4/5.8% -> 9.1/5.7% (unchanged, within noise) So the fix IMPROVES LEARNING but NOT the metric. **RETRACTION OF THE PREVIOUS JOB'S CLAIM.** It reported the radial head's 48.8% against a 36.7% majority baseline and concluded "conditional learning, not a constant bias". With the bias removed, the correctly-measured majority baseline is **58.2%** - so the head at 57.0% is AT/BELOW majority. The earlier apparent conditional learning was PARTLY AN ARTEFACT OF THE BIASED SAMPLE. The bmPoint metric win is real (TMRadial > Linear early 16/2 p=0.0013, overall 18/0 p<0.0001; > shuffled 18/0 p<0.0001) but it comes from a NET-POSITIVE AVERAGE RADIAL SHIFT, not from beating a majority classifier. Recorded plainly rather than left standing. Guards: test_tm_pattern_registration 20 (new), test_tm_pattern_rack_live 4 (new), test_gun_harness 39, test_vbullet_metric 11, test_power_selection 3 (the SIGSEGV is gone - the knn_gun rewrite is now committed), test_adaptive_radar 41, test_tfil_ring_weights 24, test_power_policy 26, test_ram_decision 28, test_rack_membership 38, test_selector_tiebreak 19, test_tm_pattern_learning 3, acceptance_offline_vs_online 12/12. ModularBot compiles (release). Note: `common_libs/tests/range_guns.nim` still builds 14 offline drivers (the offline sweep constructs TmPatternGun directly and acceptance only inspects ids 0..13), so nothing breaks - but a future job wanting it in the offline rack must add a 15th driver and mirror the live admission gating. gun_stats.jsonl now emits 15 rows; downstream tooling should ignore id 14. |

racks: separate melee and 1v1 gun racks, plus per-mode real hit-rate data
The user's plan: "separate racks for melee and 1v1, so the bot switches from those based on the situation, and we can put the guns we want in one or both racks." MECHANISM - `RackMode` (rm1v1/rmMelee) derived from SERVER TRUTH: `rackMode(enemyCount)` = 1v1 when the count is 1, melee otherwise. This is the SAME `getEnemyCount()` value the radar already uses, so there is now ONE definition of the mode. (Using the tracker's known-enemy count was a previous bug in the radar: it read 1 before the second enemy was scanned.) - `RackMembership` per gun: both (default) | 1v1 | melee | off. - The selector ranks only admitted guns - including the floor path and the incumbent-hysteresis path. - Empty filtered set FALLS BACK to the full rack, so the bot can never end up with no gun. - Env-overridable at process start, no rebuild: `TR_RACK_<GUN>` for all 14 guns (TR_RACK_HEADON, TR_RACK_LINEAR, ... TR_RACK_TMSELECT), values both|1v1|melee|off. Empty/unknown -> both + a stderr warning, never fatal. - `[rack] mode=<1v1|melee> active=<guns> overrides=<...>` logged once per mode change, never per tick. DEFAULT IS UNCHANGED: every gun ships `rmBoth`, so behaviour is byte-identical until the user re-racks anything. Verified by the unit test's default-config selection parity (RNG draw for RNG draw) and by `test_gun_harness` 39 and acceptance 12/12. `chooseFromFit` iterates the admitted list in ascending id order, so the random tie-break draws are unchanged. NO TUNING DONE, deliberately: we had no per-gun melee hit-rate data, and an earlier 15-paired-run experiment found pruning neutral-to-negative on hit rate (p=0.57/0.21). So all guns stay `both` and the membership pass waits for data. PER-MODE DATA PLUMBING (this is what unblocks that pass): per-gun real shot accounting is now split by the rack in force at fire time, adding to gun_stats.jsonl: realShots1v1, realHits1v1, realHitRate1v1, realShotsMelee, realHitsMelee, realHitRateMelee. Verification: test_rack_membership 38/38 (new, pure, no battle); test_gun_harness 39, test_vbullet_metric 11, test_power_selection 3, test_adaptive_radar 41, test_tfil_ring_weights 24, test_power_policy 26, test_ram_decision 28; acceptance_offline_vs_online 12/12 VERDICT PASS; ModularBot compiles. The live `[rack]` line was observed switching 1v1 -> melee when the enemy died. The offline range never calls the selector (only spawnBullets/tickBullets/ reportFor), so mode filtering cannot change the offline result and no offline mode parameter was needed - confirmed by reasoning over the source and by 12/12. |

ramming: make the decision PROACTIVE, with a bullet-rain abort
The user watched 1v1 and melee runs and saw ram opportunities arise that the bot
declined: "there were moments where the bot could jump over the enemy and shred
it but shot it down instead."
DIAGNOSIS - a chicken-and-egg loop. `ramOpportunity` required dist < 50px, but
an offline measurement over 15 rounds vs DrussGT found the closest approach was
118.7px and the <50px trigger had NEVER fired: the mover has no reason to close,
so the trigger waited for a proximity nothing created. The MECHANISM to close
already existed (the ring mover expresses a ram as band=(0,50)); what was
missing was a decision that fires at a range the bot can actually close from.
Changes:
- opportunity gate relaxed: dist 50 -> TR_RAM_OPP_DIST (200), energy margin
+30 -> TR_RAM_OPP_MARGIN (15). Both env-tunable, no rebuild needed.
- New pure module `common_libs/movements/ram_decision.nim` holding the trigger
and abort logic (no battle/API deps), so it is unit-testable.
- BULLET-RAIN ABORT (the user asked for this earlier): `onHitByBullet` now
accumulates `e.bullet.power` into a 15-turn ring; damageRatePerTurn = sum/15;
an in-progress ram aborts when rate > TR_RAM_ABORT_DMG (0.5/turn). On abort:
isRamming=false, cooldown 30, TARGET KEPT, and the mover returns to the normal
range band. It never stops the bot.
- Opt-in, DEFAULT-OFF `plan` trigger for "change of plan when the gun duel is
failing" (dist<250, margin+20, selected gun's pooled virtual rate < 0.05).
Left off because a cold gun reads 0.0 and would qualify - speculative.
- `TR_RAM_LOG=1` change-gated line: `[ram] ON reason=opportunity dist=143
selfE=78 enemyE=41 cap=3.0 band=[0,50]` / `[ram] OFF reason=bulletRain`.
- Existing cooldown/duration/stuck machinery untouched (stuck>10 or duration>60
-> abort + cooldown 30). A refactor bug that briefly DROPPED the
`ramCooldownTicks == 0` gate was caught and fixed.
Trigger set (first match wins): finisher (dist<300, enemy<20, we are healthier);
opportunity (dist<200, we lead by 15+); desperation (both <5, dist<150); plan
(off). All require enemy>0, a valid target, and no cooldown.
Proof the intent now fires at a closable distance (28/28 unit checks):
PASS: opportunity fires at dist 143 with a 37-energy lead <- the exact case
PASS: old gate (dist<50, margin+30) does NOT fire at 143 <- the old bug
PASS: fires at 199px / does NOT fire at 201px
+ margin, finisher priority, desperation, plan on/off, window mean, abort
threshold checks.
HONEST FRAMING: ram damage is 0.6 per CONTACT EVENT, one-shot (collision
resolution rewinds positions so contacts do not stream) - small next to a p=3.0
bullet hit (16). The payoff is that point-blank forces hit probability toward 1,
so heavy bullets stop missing and E[dE]=p(3P-1) turns positive above P=1/3; ram
damage also scores 2.0/point (highest in the game) and a ram kill carries a 0.30
bonus vs 0.20. So this is "force the fight to point-blank", not "the ram shreds
them". Base rate is rare (2 collisions in the whole fixture corpus).
Guards: test_ram_decision 28 (new), test_power_policy 26, test_gun_harness 39,
test_vbullet_metric 11, test_power_selection 3, test_adaptive_radar 41,
test_tfil_ring_weights 24. Compiles (release).
UNVERIFIED: the live effect. No A/B has run, and whether the mover actually
reaches contact is unproven.

power policy: cap power by range and energy, gate 3.0 on above-average chances
Implements the user's energy management request: "firing from more than 200px should be a 'not good chances zone' so faster bullets and more chances to hit matters more than single hit damage with low chances. When we are lower than 50 health, same thing. I would like to use 3.0 power only when the chances of hitting are higher than average." Design: a CAP on top of the existing `bestPower`, not a rewrite. `bestPower` still answers "which bin does this gun's own data prefer"; the policy caps it: ramming -> 3.0 (reason ram, exempt) dist > TR_POWER_FAR_DIST (200) -> 1.0 (far) elif selfEnergy < TR_POWER_LOW_ENERGY (50) -> 1.0 (lowEnergy) elif pEst <= pRef -> 2.0 (belowAvg) else -> 3.0 (full) power = min(gunPreferredBinPower, cap) # can only LOWER power p=1.0 is the right "low" tier on the measured mechanics: bullet speed 20-3p so p=1.0 gives speed 17 vs 11 at p=3.0 (55% faster = less lead error), fire interval 10+2p so 12 ticks vs 16 (33% more shots), and drain 0.083/turn vs 0.1875 (2.25x slower). All three things the user asked for at long range. pEst = the chosen bin's virtual rate (gun aggregate when the bin is empty); pRef = the gun's aggregate mean unless TR_POWER_REF > 0. No-data guns are vacuously below-average -> cap 2.0 (conservative, documented). Control arm: TR_POWER_POLICY=0 = uncapped = today's behaviour exactly. Knobs: TR_POWER_POLICY, TR_POWER_FAR_DIST, TR_POWER_LOW_ENERGY, TR_POWER_FAR_CAP, TR_POWER_MID_CAP, TR_POWER_REF, TR_POWER_LOG. TR_POWER_MID_CAP exists because the user did not specify the middle case (close + healthy + not-above-average); 2.0 is the default, flippable to 1.0. Seam: the cap lives in a pure `applyPowerPolicy` and is applied only in `selectShot` (the single place real shots are chosen), so the logic is testable without a battle. Ram is wired from `shouldRam` - the same value the movement dispatch uses for the (0,50) band. CORRECTION TO AN ASSUMPTION IN THE TASK: `offline_range.nim` does NOT call `bestPower`/`selectShot` - it only replays virtual-bullet spawn/resolve across all power bins, independent of the real shot's power. So there is no offline power-selection path that could diverge from the live one, and the acceptance test guards the metric, not the policy. Policy coverage therefore comes from the new unit test. Verification: test_power_policy 26/26 in BOTH modes (default and TR_POWER_POLICY=0 control arm); test_gun_harness 39, test_vbullet_metric 11, test_power_selection 3, test_adaptive_radar 41, test_tfil_ring_weights 24; acceptance_offline_vs_online 12/12 VERDICT PASS (live battle). ModularBot compiles. UNVERIFIED: the live effect on damage/survival/score. No A/B has run. |

movement: range-weighted TFIL variant + tamed heat field (opt-in, default unchanged)
New mover `the_floor_is_lava_ring.nim`, a COPY of `the_floor_is_lava.nim` (which stays byte-identical - the user explicitly wants the current TFIL preserved). Selected only via `TR_MOVEMENT=tfil_ring`; the default stays `tfil`. WHY: our measured real hit rate vs DrussGT is strongly range-dependent - 21.6% at 0-100px, 27.1% at 100-200px, 19.3% at 200-300, 10.9% at 300-400, 6.8% at 400-600, 5.4% at 600-800 - but we shoot from ~450px on average. Plain TFIL has no range preference at all. THE ONE CHANGE: the final tile draw is re-weighted toward a target band. rangeW(d) = 1.0 if lo<=d<=hi; exp(-((lo-d)/K)^2) if d<lo; exp(-((d-hi)/K)^2) if d>hi w_i = rangeW(d_i)^(1/T); chosen ~ Categorical(w) FLAT TOP on purpose: a Gaussian centred on the band midpoint would collapse the band to a point and destroy the within-band hedge. `T` is the only knob; `TR_TFIL_RANGE_TEMP=0` gives plain `rand(candidates.high)` - the exact control arm. Safety stays a HARD constraint: the weighting only reorders the draw among the pool the old code already accepted, so it can never pick a tile the old code rejected (monotone refinement). Small pools (<4) stay uniform. Randomness is deliberately KEPT: a measured A/B showed committing to the "best" tile made real hit rate WORSE (7.02% -> 5.10%), so the distribution is tilted, never removed. HEAT TAMING (ring copy only; env-overridable): TR_TFIL_CORRIDOR_HEAT 20.0 -> 5.0 TR_TFIL_WALL_HOTNESS 30.0 -> 10.0 Rationale, measured: `CorridorHeat=20` is TWICE `PathDangerThreshold=10`, so a single corridor could poison a path by itself; `WallHotness=30` with `WallRadiance=10` put the outer two tile rings over threshold on their own. Per-source shares of total lava: wall 60.6%, corridor 25.4%, pillar 7.4%, everything else <3%. MEASURED EFFECT (primary fixture, 20,026 ticks / 15 rounds, field identity verified max diff 0.000e+00): metric original(20/30) ring(5/10) band-weightable ticks 10.79% 26.45% mean safeTiles/tick 15.19 85.04 ticks with 0 safe (pre-fallback) 58.5% 7.5% safePool >= 4 39.05% 92.47% >=1 safe tile in 100-200px 11.84% 26.64% MEAN CLOSEST-SAFE-TILE DISTANCE 397.78px 284.84px tiles > 10 threshold 0.61 0.15 The 397.78px figure is why the bot stayed far away: the safety filter left nothing safe near the target, and 397px is our WORST range. Control: setting corridor=20 wall=30 reproduces the original baseline exactly. CEILING, honestly: even at corridor 0 / wall 0 only ~40% of ticks are band-weightable, so no constant tweak fully unlocks the range weighting. Ram unification: the ring mover takes a `band` field; ramming becomes just `band=(0,50)`, so there is one movement engine. The `tfil` path is unchanged. Observability: magenta annulus at the band edges, candidates tinted by weight, chosen tile marked; one `[tfil_ring]` log line on change (now including corridorHeat/wallHotness). Guards: test_tfil_ring_weights 24/24 (new, pure, no battle), test_gun_harness 39, test_vbullet_metric 11, test_power_selection 3, test_adaptive_radar 41. UNVERIFIED: the mover's live effect. It has not been run in a battle yet. |

tracker: corpses do not exist - revert the fix and retire the workaround
The belief "BotDeathEvent never reaches ModularBot, so enemyTracker keeps dead
enemies alive forever" was written into a code comment and then believed twice.
It is FALSE. Measured in a 7-bot melee with a per-tick probe comparing
enemyTracker's alive count against the server's getEnemyCount():
metric 1.3.1 (20 rd) 0.35.5 (15 rd)
observed enemy deaths 83 68
...non-round-ending 83 (100%) 66 (97%)
ekBotDeath events DROPPED 0 0
max dispatch lag (turns behind) 1 1
phantom ticks 1 / 16,820 1 / 12,596
MAX CORPSE LIFETIME 0 ticks 0 ticks
victims still alive at round end 0 0
onBotDeath fires for every death, including non-round-ending ones. The
API-level event-drop mechanism IS real (test_event_drop_mechanism.nim proves
it: ekBotDeath is not in isCritical and MAX_EVENTS_AGE=2) - the bot simply
never falls far enough behind for it to trigger (max lag 1 turn).
Removed:
- reconcileWithServer + ReconcilePersistTicks/mismatchTicks/sawServerAlive
(uncommitted, and ON BY DEFAULT despite the premise being false). Its own
comment admitted a shorter window once KILLED A LIVE ENEMY ("it fired three
more times after the tracker marked it dead") - a latent mis-prune path
defending against a bug that does not exist.
- The radar's CorpseTicks=40 filter and the same-class age>60 filter in
recordRadarStats, both carrying the false comment. Removal changes no real
behaviour: buildState feeds the radar enemyTracker.allAlive(), so a dead
enemy never reaches computeScan.
Kept:
- The TR_TRACKER_PROBE instrument (default OFF), which produced the table above.
- test_event_drop_mechanism.nim - the drop mechanism is a genuine library
behaviour worth guarding.
- isAlive/aliveCount on the tracker.
Added: docs/tracker_death_events.md (the durable negative, so this is not
re-invented a third time) and test_enemy_tracker_death.nim (13 checks) in place
of the test for the deleted feature.
Guards: test_gun_harness 39/39, test_vbullet_metric 11, test_power_selection 3,
test_adaptive_radar 41/41, test_event_drop_mechanism 6, test_enemy_tracker_death

feat(radar): adaptive melee radar sweeps only the arc containing all enemies
Replaces melee_scan in the rack. melee_scan spun the radar at the 45 deg/tick cap unconditionally, so a full 360 deg revolution took 8 ticks and every enemy was scanned roughly every 8 ticks. The new module starts with the same full spin, and once it is SURE it has covered every enemy it sweeps back and forth over only the minimal covering arc of all enemy bearings. MEASURED, real melees via the bridge, per-enemy onScannedBot counts: 3-bot melee (2 enemies): 29.6 -> 61.1 scans/100 melee-ticks (2.06x) 4-bot melee (3 enemies): 36.0 -> 75.7 scans/100 melee-ticks (2.10x) Covering-arc widths observed: mostly <90 deg in the 2-enemy case, up to 240 deg in the 3-enemy case, so the gain shrinks as the arc widens - and at the ExitTrackWidthDeg=300 fallback it degenerates to exactly the old full spin, so there is no loss when narrowing would not help. TRADEOFF, recorded rather than hidden: a wider arc legitimately takes longer to traverse, so the freshness window costs 5-7 points (fresh<=16: 93-95% vs 98-100%) and more at fresh<=8 (75-76% vs 97-100%). More scans per enemy, at slightly staler individual fixes. DESIGN: acquisition spins 360 until every live known enemy was seen within FreshnessTicks=16 (two revolutions of slack), no new id appeared, and the live count matches getEnemyCount(); that must hold FreshStreakTicks=3 consecutive ticks. Tracking then bang-bang sweeps the wraparound-aware covering arc (350+10 -> 20 through 0) widened by MarginDeg=20 each end, at up to 45 deg/tick. Fallbacks return to acquisition: any stale enemy, any new id, or an arc >= 300 deg. Enter 270 / Exit 300 gives 30 deg of hysteresis so it cannot flap. Adds EnemyInfo.lastSeenTick (additive) so coverage is judged on staleness, not mere knowledge - without it an enemy that slipped behind the sweep would keep contributing its own stale bearing, which is self-confirming. The offline range now round-trips that field from the fixture 'lst'. COMPANION FIX, and it matters: the radar-mode switch used the TRACKER's known enemy count, so in melee the bot saw one enemy before scanning the second, locked to 1v1, and the melee radar never ran at all. Now uses getEnemyCount() (server truth), so melee mode persists until one enemy is genuinely left. 41 new unit checks (wraparound arcs, straddle at 0/360, single/empty enemies, the 45 deg/tick cap, every phase transition and fallback). melee_scan is kept but marked DEPRECATED; nothing in the rack imports it. Non-regression: 33 gun-harness checks, vbullet metric, power selection, and 12/12 offline==online acceptance all pass. |

fix(logging): [config] reported a stale gun - it printed before selection ran
The user spotted this from the game itself: the [config] line always said
gun=HeadOn while the in-game turret and bullet COLOURS varied. The colours are
set at the selection site, so they were truthful and the log was not.
MEASURED, one 2-round battle, same process:
[config] output : 6 lines, ALL gun=HeadOn
tracker selection : Displace 25.1%, HeadOn 20.8%, Pattern 15.5%,
KNN 14.1%, Tsetlin 6.3%, WallBounce 6.1%, ...
Root cause: printConfig did GunNames[bot.currentGun] but EVERY call site ran
before the tick's gun selection - onRoundStarted right after currentGun = 0
(so HeadOn by construction), and the target/radar-change prints. The selection
that sets currentGun is ~490 lines later in the same tick. radarMode and
currentTargetId ARE updated before those sites, which is exactly why the radar
and target columns looked plausible while the gun column did not.
WHERE IT CAME FROM: git history shows commit

fix(test): repair the flaky offline==online acceptance; make the tie-break truly random
TASK 2 - THE FLAKY ACCEPTANCE TEST, root-caused. It was NOT a live/offline boundary race as suspected. The replay spawned gun 13 (TMSelect) while live has EnableTmSelector = false and never does. The shared VirtualTracker ring is ORDER-SENSITIVE, so gun 13's extra 4 bullets/tick shift the ring head and permute the per-tick RESOLUTION ORDER of every other gun. The learning guns append observations in resolution order, so their predictions shifted and produced small hit deltas that moved between runs. Evidence: the first KNN divergence was at rtick=174 with the SAME resolution set merely reordered (live ft133,138,139,142,148,150,151 vs offline ft150,151,133,138,139,142,148); after closing gun 13's ready gate offline the live and offline KNN traces became BYTE-IDENTICAL (diff empty, 904/904 lines). Fix: mirror the live rack in the replay. No tick exclusion, no tolerance loosening. Stability: 5/5 consecutive runs now report 12/12 exact, each with enemyDied=true - the death boundary is included, not excluded. The proof is now real rather than a lucky run. TASK 1 - the tie-break was not random. randomize() was only reached incidentally through initTsetlinGun(), so a rack without Tsetlin had a fixed rand() stream and ties always resolved the same way across process restarts. Added seedSelectorRng() after gun construction, honouring GUN_SELECTOR_SEED. Evidence: unseeded, 6 separate processes gave different pick sequences; with GUN_SELECTOR_SEED=42, 3 processes gave identical sequences. TASK 3 - PRUNING DOES NOT HELP; keep the full rack. 15 PAIRED runs per variant vs DrussGT, 8 rounds, identical seeds: baseline 3238 shots 6.18% (events 6.16%) 200 dmg/run Tsetlin disabled 3522 shots 5.76% (events 5.71%) 197 dmg/run Tsetlin+Displace 3478 shots 5.46% (events 5.37%) 183 dmg/run Paired permutation tests: -0.34pp p=0.57 and -0.70pp p=0.21. Per-run distributions completely overlap (baseline range [2.68, 10.00]; 15/15 and 14/15 runs inside it). A Crazy control showed no separation either. So removing the measured-worst real performers is neutral-to-slightly-negative, and with sd ~1.8pp a definitive claim either way would need far more runs. CORRECTION TO A CLAIM I MADE: the 'virtual metric is INVERTED' finding does NOT reproduce. Job-24 measured Spearman -0.374; this job measures +0.335 over the same 13 guns with a different but equally defensible aggregation. Two opposite signs means the correlation is NOT robustly negative - it is WEAK AND SIGN-UNSTABLE. The honest statement is that virtual hit rate is a poor ranker, not an inverted one. The docs assert the inversion and need correcting. Also adds per-process GUN_STATS_PATH/GUN_SHOTLOG_PATH so concurrent A/B runs do not clobber each other, and an env-gated GUN_RACK_DISABLE for rack A/Bs. All default behaviour is unchanged when the env vars are unset. |

feat(guns): scale-aware power selection (+52% damage); TM classifier gun built, measured, DISABLED
TASK 2 - power selection, a clear win. bestPower used an ABSOLUTE MinHitRate = 0.40 bar. Measured per-bin virtual rates (rolling-100 fraction) show no bin ever clears 40%, so 11 of 14 guns were stuck at bin 0 (power 1.0) even where higher bins were comparable: Linear p1.0 44% p1.5 39% p2.0 30% p3.0 29% old bin 0 -> new bin 3 Accel p1.0 44% p1.5 40% p2.0 26% p3.0 29% old bin 1 -> new bin 3 Pattern p1.0 50% p1.5 40% p2.0 27% p3.0 12% old bin 1 -> new bin 2 Replaced with a scale-aware PowerBarFrac = 0.50 (a dimensionless FRACTION of the gun's own best bin rate). 13 of 14 selections now pick heavier bullets. Real effect vs DrussGT (8 rounds x 3 runs): hit rate unchanged (7.56% -> 7.47%) but damage dealt +52% (157 -> 239 per run) and rounds end faster. Same accuracy, half the shots, half again more damage. TASK 1 - the TM pattern-classifier gun does NOT earn its slot. It was built as a mixture of experts with a corrected-Granmo TM as a multi-class gate over HeadOn/Linear/Circular/WallBounce/Accel, labelled by which expert's prediction was closest to the actual enemy position (an exact, supervised, per-shot label - no delayed credit). Offline it loses to the best of its OWN experts on essentially every fixture, and against DrussGT it cost real performance: baseline (path+relative) 7.56% real hit rate, damage 157 + power fix 7.47%, damage 239 + power fix + TM gun 5.59%, damage 133 The gun was selected on 806 ticks and fired 24 real shots at 4.2%. So the tree ships with EnableTmSelector = false: code and wiring kept intact for re-enabling, but it is not in the active rack. Worth recording from the clause dump: the gate DOES latch onto meaningful structure. On energy-threshold-turner, HeadOn's clauses key on the energy bits (the rule's own driving variable) while Circular keys on distance/velocity. So the TM is learning something real and interpretable - it simply cannot beat 'always pick the best expert'. Root cause (INFERRED): the closest-expert label is noisy because several experts are near-tied, and under the path metric the winner varies by power bin while the gate sees one shared per-tick input, so a one-vs-rest gate over a saturated 870-bit clause space has no margin to exploit. (Zero-padding the 2-frame window was tried first and saturated every clause at 256-755 included literals; alternating the two real frames fixed that.) Also factors the corrected feedback into an exported tmLearnDir and exports the encoding/TM primitives; the Tsetlin tests still reproduce the documented mean=13.8 included literals, so the refactor is behaviour-preserving. Verified: 33/33 guard checks, tsetlin tests green, metric checks green, new power-selection guard green (13/14 selections change; relative bar still picks bin 1 and not bin 3 for a [30,25,12,5]% profile), 12/12 offline==online acceptance under the shipped default. |

test(range): restore the 12/12 offline==online proof; measure TM clause readability
Task 1 - the acceptance proof was unrunnable because RecordWorldState was a
compile-time const set to false. It is now a RUNTIME switch
(let RecordWorldState* = existsEnv("TR_RECORD_WORLDSTATE")), default OFF, so
ordinary runs write no fixture, and acceptance_offline_vs_online.nim enables
it for the battle it spawns and clears it afterwards. Restored and run twice:
12/12 deterministic guns match exactly (128-tick and 546-tick battles), with
Tsetlin reported separately as stochastic. Both nimble build variants clean.
Task 2 - does a compact encoding turn the TM's 99.35% into a READABLE rule?
Measured across window sizes (fixed seed, no tuning):
frames TEST acc eff.lits/clause firing clauses counterfactual low/high/mean
10 99.35% 152.8 37 100/24/62.4%
3 95.94% 54.9 35 96/20/58.6%
2 99.48% 39.6 38 95/25/60.7%
1 98.30% 19.2 45 100/24/62.3%
So 2 frames is strictly better than 10 on BOTH axes: +0.13 accuracy for 4x
smaller clauses. The 3-frame dip is non-monotonic and left unexplained rather
than smoothed over.
A readable rule WAS partially recovered. Five clauses carry the exact Gray
form !g10 ^ !g9 ^ !g8; g10 is inert in this data, so the effective rule is the
2-literal proposition !g9 ^ !g8, i.e. energy < 25.6. That is a genuine
threshold in readable propositional form - but at 25.6, NOT the labelled 30,
because 256 is a power-of-two Gray boundary expressible in two literals while
300 needs a longer conjunction. The TM found the nearest SIMPLE threshold.
The honest caveat: that threshold is not the ensemble's decision mechanism.
The counterfactual follow rate (high 24%, mean 62.3%) is statistically
identical at 1, 2 and 10 frames, so compactness did not make the model read
energy - its vote is carried by co-occurring bearing/velocity/heading/wall
literals. Also identified: clauses containing all 11 Gray energy bits are
satisfied at exactly one raw value (50, the dataset floor), so they are
'energy has hit the floor' detectors, not thresholds.
Methodological fix worth keeping: the earlier single-frame counterfactual
wrote energy into all 10 frame slots including the zeroed ones, reviving dead
clauses and producing a spurious 2% high-follow rate. setEnergyFrames now
rewrites only the exposed frames; the corrected figure is 24%.

feat(gun_harness): offline gun range, proven equivalent to live play
Gun evaluation previously required a full end-to-end battle (Java server + battle runner + websocket IPC to 2 bot processes, 50 rounds, ~3.4 min) and yielded only ~300-900 REAL shots across 13 guns -- far too few to rank guns, which is why tuning needed many repetitions. VirtualTracker is already a pure function of (WorldState stream, gun list); the only reason it needed Java was where WorldState came from. So the range replays a seq[WorldState] through the SAME tracker: offline and online scores are the same metric by construction, not an approximation. ACCEPTANCE TEST (the point of the whole thing): record one live round, replay it offline, compare per-gun virtual hit rates. 12/12 deterministic guns match EXACTLY, reproduced twice. Tsetlin is compared separately because tmLearnOne calls rand(). Getting to 12/12 exposed two real ordering quirks in the live loop: run() calls go() before the aim/fire block, so tickBullets resolves against the NEXT tick's scan while the prediction used the previous one; and if the target dies during that go() the final tick's spawn+resolution is skipped entirely. The recorder emits an end marker for the second case. The 5th (selected-gun) predict call was verified to be a no-op. Measured cost: 8 fixtures (1770 ticks, ~92k virtual bullets, 13 guns) replay in 2.9 s, ~32k virtual bullets/s -- roughly 70x faster and 100x more samples than a live gauntlet. Also adds a per-tick WorldState recorder behind const RecordWorldState (default off, mirrors the ShotLog idiom) which records the state the bot ACTUALLY builds, staleness included, rather than true positions -- recording the latter would hand the guns perfect information and produce flattering scores. 9 new guard checks (33 total, all passing), including fixture round-trip, replay determinism, stationary->HeadOn 100%, constant-velocity->Linear>HeadOn, and the energy-threshold turner crossing at t=41. |

feat(selector): range-aware firing gate fitted to 2611 measured shots
Measured, not assumed. With the gate temporarily opened to 20 deg, every real shot was logged (tick, angle error at fire time, distance, power, hit) across 3 gauntlets: 2611 shots, 57.3% aggregate. Findings: - The geometric cone atan(BotRadius/d) is directionally confirmed but a WEAK lever: even at 0.0-0.1 deg error the hit rate at 400-600px is only ~53-57%, because PREDICTION error dominates alignment error. - Real effect of tightening the gate: 57.9% -> 68.0% aggregate hit rate (fixed 0.1 deg), not the 76.9% previously reported -- that was a high-variance draw (per-rep 62.8/66.4/77.2%). - The shipped range-aware gate (SafetyFactor 0.6) does NOT beat the fixed 2.0 deg gate on hit rate (55.8% vs 57.9%, ~1.5 sigma, inside noise). It fires 22-28% more shots and therefore lands more total hits (~509 vs ~434 per rep). No per-adversary score delta exceeded the 300-point run-to-run noise band, so no config is demonstrably better on score. Shipped anyway because it is strictly more expressive (a fixed threshold is the special case), tunable from one const, and physically motivated, but the honest verdict is recorded in-code: the gate is not the bottleneck. AimThresholdDeg is removed; shouldFire now takes distPx. Degenerate or NaN distance falls back to the ceiling rather than dividing by zero. Also adds a per-shot logger to ModularBot behind 'const ShotLog' so the measurement above is reproducible, and 10 new guard checks (24 total, all passing) covering monotonicity, clamping, formula, perfect alignment, gross misalignment and degenerate distance. Cross-checked against the server source: the gun fires BEFORE the turn is applied, so the logged angle error is the true departure error, and fireAssist auto-aim is off (unset by the Nim API and forced false by setAdjustRadarForGunTurn). |

fix(guns): per-bin wave queues unbreak GF/DecayGF/KNN learning; fix vbullet drops
Wave queues (guess_factor, decay_gf, knn_gun): predict() stored ONE wave per tick while onResult() popped one per resolved bullet (~4/tick), so the queue drained to empty within a few dozen ticks, ~3 of every 4 resolutions returned without learning, and the survivor paired with a same-tick wave (bearingDelta ~= 0) pinning the histogram at centre. PROOF: GF.vHits == HeadOn.vHits and DecayGF.vHits == HeadOn.vHits byte-for-byte in every one of 50 rounds — the guns had degenerated to HeadOn. Now each gun keeps a per-bin FIFO with an O(1) head cursor. At most one push per (tick, bin) so the fire site's 5th predict() call is a no-op, and onResult pops the oldest wave of its OWN bin via e.bulletPower. Aiming math untouched (it was already correct: 0 deg = East, CCW+). maxBullets 2048 -> 8192: the rack spawns 52 bullets/tick so the ring wrapped every ~39 ticks while a long power-3 shot needs ~90, silently discarding unresolved bullets and biasing every measured hit rate by range. Added a droppedBullets counter so a future overflow is measurable, and wavePushes/ waveStarved counters on the three guns. After the fix: vDropped = 0 and vStarved = 0 across all 48 recorded rounds. fitnessFor is now exported, deterministic (enemies iterated in ascending id order) and shared by the selector and the stats dump, replacing a hand-rolled merge in ModularBot that never advanced its window head. Round lines gain additive keys: vDropped, vStarved. |

feat(gun_harness): per-gun REAL hit attribution + bestPower cold-start fix
Attribution is proven, not guessed: the server assigns a per-round-unique bulletId (GunEngine.nextBulletId) and stamps the same id on BulletFired, BulletHitBot, BulletHitWall and BulletHitBullet. Keep a FIFO of fired gun ids, stamp bulletId -> gunId on onBulletFired, resolve through that map. Hits are deferred when onBulletHit precedes onBulletFired in the same turn (client dispatches priority 70 > 60), which recovered 14 unattributed hits. 99.9% of shots and 99.8% of hits attributed. Stats lines now carry per-gun realShots/realHits/realHitRate; the old keys and round-level totals are unchanged. bestPower: a gun with zero observations in every bin previously returned the HIGHEST bin (power 3.0) because an empty bin satisfied the 'count == 0' clause on the first countdown iteration. Cold guns now return the lowest bin as the docstring always claimed. Warm-gun path untouched. |
