TFIL: measure the commitment A/B on 490 live DrussGT rounds - no effect

Browse Source 
Runs the five-arm commitment A/B that 19bf461 only implemented. One frozen
binary (git archive 19bf461, sha256 46e7ce19...) vs the real DrussGT through
tools/robocode_shim/run_bridge_battle.sh: 7 runs x 7 rounds per arm against
real DrussGT in the pre-registered block, plus an independent replication
block (runs 8-14) - 70 battles, 490 rounds, 5 arms in parallel.

  A control (shipped)          B TR_TFIL_TILE_REPLAN=off
  C B + TR_TFIL_NO_REV=1       D TR_TFIL_TILE_REPLAN=enemy
  E B + TR_TFIL_COMMIT_TICKS=30   (TR_TFIL_COMMIT_LOG=1 on every arm)

RESULT: no arm improves damage/run or round wins vs the shipped mover. Pooled
(14 runs/arm, exact two-sided permutation test over all C(28,14) relabellings):

  arm  damage/run (delta, p)        round wins (delta, p)
  A    274.44                       2.79  (39/98)
  B    274.07 (-0.37, p=0.97)       3.07  (+0.29, p=0.66)
  C    257.34 (-17.10, p=0.16)      2.43  (-0.36, p=0.47)
  D    286.61 (+12.17, p=0.36)      3.29  (+0.50, p=0.35)
  E    265.29 (-9.15, p=0.56)       2.93  (+0.14, p=0.89)

The replication is what settles it: block 1 alone showed D at +20.99 damage
(p=0.26); block 2 put D at +3.36. Nothing replicates.

The PREMISE fails. Honouring the commitment does not reduce reversals - it
raises the reversal-pick rate from 33.9% (control) to 50.9% (B) / 57.0% (E);
the no-reversal arm C only claws part of it back (42.4%). The post-reversal
speed dip (~4.9 -> ~4.0 px/tick at +1..+2 calls) is identical in every arm, so
it is a property of turning around, not of the tile replan, and arm A - the
arm carrying the bug - has the LOWEST mean abs(speed) of all five.

Both premise premises are also caught by the metric the report is careful
about: arm C takes significantly FEWER hits (87.2 vs 96.5/run, p=0.0022) while
dealing the least damage and winning the fewest rounds - a movement change
alters hits taken, shots fired and round length at once, which is exactly why
damage and round wins are the primary metrics and hit rate is not.

Treatment verified per arm from the per-tick TR_TFIL_COMMIT_LOG: the pick
interval moves off ~5 calls only where the arm says it should (A 5.05 with
96.6% tile_self replans; B 14.77 with 0%; C 14.79; D 5.29 with 95.7%
tile_enemy; E 26.62), matching the offline fixture replay (5.07 / 14.65 /
14.65 / 4.94 / 27.57). Every arm ran.

Round wins are the final RESULTS firstPlaces, cross-checked against each
round's BotDeathEvent (35/35 and 35/35 runs agree). Damage is the server's
BulletHitBotEvent damage, attributed by numeric owner/victim id and verified
against the capture's own event counters.

measure_tfil_commit_ab.nim reads the raw run artifacts (JSONL states, events
sidecar, capture stdout, commit log) and prints the whole deliverable:
arm table, per-run values, the exact per-run permutation test, the exact
round-level hypergeometric test (flagged anti-conservative - rounds cluster
within a run), the treatment diagnostics, and the direct answer. It reproduces
either report offline from the committed summary:

  nim c -r --path:common_libs common_libs/tests/measure_tfil_commit_ab.nim \
      --from-summary common_libs/tests/fixtures/tfil_commit_ab_results_runs14.json

The raw ~200 MB of battle artifacts are not committed; the committed summary
holds every per-run value plus the arm-level diagnostics.

# TFIL commitment A/B — measured
POOLED: runs 1-7 (pre-registered primary) + runs 8-14 (independent replication; 70 battles, 490 rounds). The replication can be analysed alone with --first-run 8 --runs 14.
source commit: `19bf461`
frozen ModularBot binary sha256: `46e7ce19cc7889dacc0c5add9b29928dadb757fbc6ecbdb7765cddd7813361c0`
raw artifacts (NOT committed, live only): `/tmp/tfil_ab2/out/<arm>/run<n>.jsonl` + `...events.jsonl` and `/tmp/tfil_ab2/logs/<arm>/run<n>.out` + `...commit.jsonl`
analysed runs per arm: 14 (this file is self-consistent; re-run the tool with --runs N on the raw dir for a different block)
damage = server BulletHitBotEvent damage, attributed by numeric owner/victim id and verified against the capture's own counters; round wins = final RESULTS `firstPlaces`, cross-checked against BotDeathEvent.

### Data integrity: id mapping + round-win cross-check
Round wins are taken from the final RESULTS `firstPlaces` and cross-checked against the BotDeathEvent of each round (in a TR 1v1 the round loser is the bot that died). A `WARNING` here means the two disagreed, i.e. do not trust that run.

### Round-level test (exact, anti-conservative)
Sum statistic over all rounds of the arm vs arm A only; exact hypergeometric null. ANTI-CONSERVATIVE: the rounds of an arm are not independent (rounds are clustered within a run, and a run is often 0/7 or 7/7), so this p is smaller than the per-run p by construction.
| arm | rounds won | rounds lost | all rounds pooled | exact p (round level, vs A) |
|---|---:|---:|---|---:|
| A | 39 | 59 | 39/98 | 1.0000 |
| B | 43 | 55 | 43/98 | 0.6641 |
| C | 34 | 64 | 34/98 | 0.5547 |
| D | 46 | 52 | 46/98 | 0.3872 |
| E | 41 | 57 | 41/98 | 0.8845 |
## 4. TREATMENT diagnostics (TR_TFIL_COMMIT_LOG — did the arm actually apply?)
| arm | commit calls | picks | interval (calls) | % tile_self replans | % tile_enemy | % danger | % expiry | % init | reversal-pick rate | mean abs(speed) |
|---|---:|---:|---:|---:|---:|---:|---:|---:|---:|---:|
| A | 183270 | 36190 | 5.05 | 96.6% | 0.0% | 0.5% | 2.6% | 0.3% | 33.9% | 4.69 |
| B | 178439 | 12029 | 14.77 | 0.0% | 0.0% | 4.8% | 94.3% | 0.9% | 50.9% | 5.37 |
| C | 180987 | 12184 | 14.79 | 0.0% | 0.0% | 4.4% | 94.7% | 0.9% | 42.4% | 5.47 |
| D | 173956 | 32772 | 5.29 | 0.0% | 95.7% | 0.5% | 3.4% | 0.4% | 37.6% | 4.98 |
| E | 177989 | 6640 | 26.62 | 0.0% | 0.0% | 37.0% | 61.2% | 1.7% | 57.0% | 4.91 |
Same diagnostics from the OFFLINE fixture replay (`nim c -r --path:common_libs common_libs/tests/test_tfil_commit_env.nim`, 20026 ticks, no Java):
| arm | interval | reversal rate |
|---|---:|---:|
| A control | 5.07 | 33.7% |
| B commit | 14.65 | 41.1% |
| C commit+noRev | 14.65 | 32.9% |
| D enemyTile | 4.94 | 35.6% |
| E commit30 | 27.57 | 42.0% |
The offline and live diagnostics agree on every arm: the interval moves off ~5 calls exactly where the arm says it should, so every treatment applied.
### Mean self-speed MAGNITUDE abs(sp) by offset (in calls) around a REVERSAL pick
This is the series that tests the premise 'the reversal collapses the bot's speed'. `sp` is the SIGNED speed at the call; the signed mean over the whole battle is ~0 because the bot drives backwards about half the time, so the magnitude is the informative statistic.

## 5. Direct answer
- control (shipped mover): damage/run 274.44, round wins/run 2.79 (39/98), hits taken/run 96.50, reversal-pick rate 33.9%, mean abs(speed) 4.69
- arm B (B honour commitment): damage/run 274.07 (delta -0.37, p=0.9720) -> not distinguishable from control; round wins/run 3.07 (delta 0.29, p=0.6561) -> not distinguishable from control; hits taken/run 89.00 (delta -7.50, p=0.0577); reversal-pick rate 50.9% (control 33.9%)
- arm C (C B + no-reversal): damage/run 257.34 (delta -17.10, p=0.1559) -> not distinguishable from control; round wins/run 2.43 (delta -0.36, p=0.4720) -> not distinguishable from control; hits taken/run 87.21 (delta -9.29, p=0.0022); reversal-pick rate 42.4% (control 33.9%)
- arm D (D enemy-keyed cancel): damage/run 286.61 (delta 12.17, p=0.3567) -> not distinguishable from control; round wins/run 3.29 (delta 0.50, p=0.3500) -> not distinguishable from control; hits taken/run 92.50 (delta -4.00, p=0.2132); reversal-pick rate 37.6% (control 33.9%)
- arm E (E commit 30 ticks): damage/run 265.29 (delta -9.15, p=0.5574) -> not distinguishable from control; round wins/run 2.93 (delta 0.14, p=0.8865) -> not distinguishable from control; hits taken/run 92.36 (delta -4.14, p=0.2078); reversal-pick rate 57.0% (control 33.9%)
**NO ARM improves damage/run or round wins vs the shipped mover at p < 0.05.** Best point estimate on damage/run is arm D (delta 12.17); best on round wins/run is arm D (delta 0.50). Neither is statistically distinguishable from control at this n.
PREMISE CHECK (the bug report claimed the tile-change replan cancels the commitment, the reversals it causes are what get us hit):
- The cancel IS real and dominant in the shipped mover: arm A ends its commitment because of OUR tile change for 96.6% of picks at a 5.05-call interval. Arms B/C/E remove it (0.0% tile_self replans, interval 14.77 / 26.62) and arm D re-keys it to the enemy tile (95.7% tile_enemy).
- But honouring the commitment does NOT reduce reversal picks: the reversal rate RISES from 33.9% (control) to 50.9% (B) and 57.0% (E). The no-reversal arm C only claws part of that back (42.4%), still above control.
- The speed dip after a reversal is present in EVERY arm (see the profile table: ~4.9 -> ~4.0 px/tick at offsets +1..+2), i.e. it is a property of turning around, not of the tile replan. Arm A -- the arm carrying the bug -- actually has the LOWEST mean abs(speed).

# TFIL commitment A/B — measured
PRE-REGISTERED PRIMARY BLOCK: runs 1-7 per arm (35 battles, 245 rounds), 5 arms in parallel, 7 runs x 7 rounds each.
source commit: `19bf461`
frozen ModularBot binary sha256: `46e7ce19cc7889dacc0c5add9b29928dadb757fbc6ecbdb7765cddd7813361c0`
raw artifacts (NOT committed, live only): `/tmp/tfil_ab2/out/<arm>/run<n>.jsonl` + `...events.jsonl` and `/tmp/tfil_ab2/logs/<arm>/run<n>.out` + `...commit.jsonl`
analysed runs per arm: 7 (this file is self-consistent; re-run the tool with --runs N on the raw dir for a different block)
damage = server BulletHitBotEvent damage, attributed by numeric owner/victim id and verified against the capture's own counters; round wins = final RESULTS `firstPlaces`, cross-checked against BotDeathEvent.

### Data integrity: id mapping + round-win cross-check
Round wins are taken from the final RESULTS `firstPlaces` and cross-checked against the BotDeathEvent of each round (in a TR 1v1 the round loser is the bot that died). A `WARNING` here means the two disagreed, i.e. do not trust that run.

### Round-level test (exact, anti-conservative)
Sum statistic over all rounds of the arm vs arm A only; exact hypergeometric null. ANTI-CONSERVATIVE: the rounds of an arm are not independent (rounds are clustered within a run, and a run is often 0/7 or 7/7), so this p is smaller than the per-run p by construction.
| arm | rounds won | rounds lost | all rounds pooled | exact p (round level, vs A) |
|---|---:|---:|---|---:|
| A | 19 | 30 | 19/49 | 1.0000 |
| B | 23 | 26 | 23/49 | 0.5406 |
| C | 17 | 32 | 17/49 | 0.8342 |
| D | 24 | 25 | 24/49 | 0.4157 |
| E | 24 | 25 | 24/49 | 0.4157 |
## 4. TREATMENT diagnostics (TR_TFIL_COMMIT_LOG — did the arm actually apply?)
| arm | commit calls | picks | interval (calls) | % tile_self replans | % tile_enemy | % danger | % expiry | % init | reversal-pick rate | mean abs(speed) |
|---|---:|---:|---:|---:|---:|---:|---:|---:|---:|---:|
| A | 91795 | 18185 | 5.04 | 96.7% | 0.0% | 0.5% | 2.5% | 0.3% | 34.1% | 4.69 |
| B | 87863 | 5920 | 14.78 | 0.0% | 0.0% | 4.5% | 94.6% | 0.9% | 51.5% | 5.37 |
| C | 91331 | 6142 | 14.80 | 0.0% | 0.0% | 4.4% | 94.7% | 0.9% | 42.4% | 5.45 |
| D | 88392 | 16595 | 5.31 | 0.0% | 95.8% | 0.5% | 3.3% | 0.3% | 37.4% | 4.99 |
| E | 88864 | 3327 | 26.52 | 0.0% | 0.0% | 38.5% | 59.8% | 1.7% | 57.4% | 4.92 |
Same diagnostics from the OFFLINE fixture replay (`nim c -r --path:common_libs common_libs/tests/test_tfil_commit_env.nim`, 20026 ticks, no Java):
| arm | interval | reversal rate |
|---|---:|---:|
| A control | 5.07 | 33.7% |
| B commit | 14.65 | 41.1% |
| C commit+noRev | 14.65 | 32.9% |
| D enemyTile | 4.94 | 35.6% |
| E commit30 | 27.57 | 42.0% |
The offline and live diagnostics agree on every arm: the interval moves off ~5 calls exactly where the arm says it should, so every treatment applied.
### Mean self-speed MAGNITUDE abs(sp) by offset (in calls) around a REVERSAL pick
This is the series that tests the premise 'the reversal collapses the bot's speed'. `sp` is the SIGNED speed at the call; the signed mean over the whole battle is ~0 because the bot drives backwards about half the time, so the magnitude is the informative statistic.
| arm | -5 | -4 | -3 | -2 | -1 | +0 | +1 | +2 | +3 | +4 | +5 | +6 | +7 | +8 | +9 | +10 |
|---|---:|---:|---:|---:|---:|---:|---:|---:|---:|---:|---:|---:|---:|---:|---:|---:|
| A | 4.67 | 4.67 | 4.71 | 4.75 | 4.84 | 4.89 | 4.24 | 4.00 | 4.10 | 4.25 | 4.39 | 4.52 | 4.59 | 4.68 | 4.79 | 4.87 |
| B | 5.95 | 5.93 | 5.87 | 5.76 | 5.58 | 5.37 | 4.38 | 3.95 | 4.12 | 4.53 | 4.96 | 5.29 | 5.60 | 5.78 | 5.87 | 5.94 |
| C | 6.08 | 6.02 | 5.94 | 5.83 | 5.66 | 5.31 | 4.46 | 4.06 | 4.21 | 4.55 | 4.87 | 5.23 | 5.58 | 5.90 | 6.04 | 6.08 |
| D | 5.15 | 5.10 | 5.07 | 5.06 | 5.03 | 4.98 | 4.42 | 4.27 | 4.39 | 4.56 | 4.70 | 4.82 | 4.90 | 5.04 | 5.12 | 5.15 |
| E | 5.03 | 4.97 | 4.88 | 4.81 | 4.66 | 4.54 | 4.26 | 4.17 | 4.28 | 4.44 | 4.58 | 4.76 | 4.94 | 5.12 | 5.27 | 5.35 |
(reversal samples per arm: A=6200, B=3047, C=2602, D=6199, E=1910)
## 5. Direct answer
- control (shipped mover): damage/run 280.38, round wins/run 2.71 (19/49), hits taken/run 95.71, reversal-pick rate 34.1%, mean abs(speed) 4.69
- arm B (B honour commitment): damage/run 281.05 (delta 0.67, p=0.9650) -> not distinguishable from control; round wins/run 3.29 (delta 0.57, p=0.6020) -> not distinguishable from control; hits taken/run 90.00 (delta -5.71, p=0.3904); reversal-pick rate 51.5% (control 34.1%)
- arm C (C B + no-reversal): damage/run 250.51 (delta -29.87, p=0.0880) -> not distinguishable from control; round wins/run 2.43 (delta -0.29, p=0.8164) -> not distinguishable from control; hits taken/run 85.71 (delta -10.00, p=0.0437); reversal-pick rate 42.4% (control 34.1%)
- arm D (D enemy-keyed cancel): damage/run 301.36 (delta 20.99, p=0.2617) -> not distinguishable from control; round wins/run 3.43 (delta 0.71, p=0.4312) -> not distinguishable from control; hits taken/run 93.29 (delta -2.43, p=0.6463); reversal-pick rate 37.4% (control 34.1%)
- arm E (E commit 30 ticks): damage/run 285.89 (delta 5.51, p=0.7121) -> not distinguishable from control; round wins/run 3.43 (delta 0.71, p=0.3019) -> not distinguishable from control; hits taken/run 96.14 (delta 0.43, p=0.9510); reversal-pick rate 57.4% (control 34.1%)
**NO ARM improves damage/run or round wins vs the shipped mover at p < 0.05.** Best point estimate on damage/run is arm D (delta 20.99); best on round wins/run is arm D (delta 0.71). Neither is statistically distinguishable from control at this n.
PREMISE CHECK (the bug report claimed the tile-change replan cancels the commitment, the reversals it causes are what get us hit):
- The cancel IS real and dominant in the shipped mover: arm A ends its commitment because of OUR tile change for 96.7% of picks at a 5.04-call interval. Arms B/C/E remove it (0.0% tile_self replans, interval 14.78 / 26.52) and arm D re-keys it to the enemy tile (95.8% tile_enemy).
- But honouring the commitment does NOT reduce reversal picks: the reversal rate RISES from 34.1% (control) to 51.5% (B) and 57.4% (E). The no-reversal arm C only claws part of that back (42.4%), still above control.
- The speed dip after a reversal is present in EVERY arm (see the profile table: ~4.9 -> ~4.0 px/tick at offsets +1..+2), i.e. it is a property of turning around, not of the tile replan. Arm A -- the arm carrying the bug -- actually has the LOWEST mean abs(speed).

## TFIL commitment A/B — measurement harness.
##
## Consumes the raw artifacts produced by the five-arm, seven-run, seven-round
## A/B against the real DrussGT bridge (tools/robocode_shim/run_bridge_battle.sh)
## and reports
##
## 1. the arm table: damage/run, ROUND WINS, hits taken, shots, per-run values
## 2. the exact two-sided permutation p for damage and for round wins
## 3. the per-arm TREATMENT diagnostics (from TR_TFIL_COMMIT_LOG): decision
## interval, % tile-change replans, reversal-pick rate, speed profile
## around reversals — this is what proves the treatment actually applied
##
## Expected raw layout (produced by the A/B driver):
## <raw>/out/<ARM>/run<r>.jsonl per-tick states (ex/ey = DrussGT, sx/sy = us)
## <raw>/out/<ARM>/run<r>.events.jsonl fire/hit/death events (numeric bot ids)
## <raw>/out/<ARM>/run<r>.rounds.json round boundaries (startTick/count)
## <raw>/logs/<ARM>/run<r>.out capture stdout (final RESULTS block)
## <raw>/logs/<ARM>/run<r>.commit.jsonl TFIL per-tick commit diagnostics
##
## Modes:
## nim c -r --path:common_libs common_libs/tests/measure_tfil_commit_ab.nim \
## --raw /tmp/tfil_ab2 --summary common_libs/tests/fixtures/tfil_commit_ab_results.json \
## --report common_libs/tests/fixtures/tfil_commit_ab_report.md
## ... --from-summary <json> # re-print the report from the committed summary
##
## NOTE on the ingredients, because they are easy to get wrong:
## * In the shim's JSONL, `e*` is the capture SUBJECT and `s*` is the other bot.
## run_bridge_battle.sh is invoked with `--subject DrussGT`, so `e*` = DrussGT
## and `s*` = ModularBot (the bot under test). Verified here by matching the
## events sidecar's bullet origins against both recorded positions.
## * The "[capture] ROUND n" stdout lines carry the CUMULATIVE score and the
## battle rank so far, NOT the round result. Round wins are taken from the
## final RESULTS block (`firstPlaces`) and cross-checked against the
## BotDeathEvent in the events sidecar (the loser of a TR 1v1 round is the
## bot that died).
## * `damage` is the server's own BulletHitBotEvent damage, attributed by
## numeric owner/victim id.
