+## OUTCOME — FINAL (read this first)
+
+**The best measured 1v1 movement is `TR_MOVEMENT=strafe`; the pre-registered
+SHIP GATE was NOT met, so the shipped default is UNCHANGED (`tfil`).**
+
+The higher-power confirmation (225 battles, 5 runs/arm, 0 invalid) measured
+`strafe` over `tfil` at **Δwins/run +0.33, 95% CI [+0.08, +0.58]** (the CI
+excludes 0 — leg 1 passes), with the incoming hit rate down **−4.75 pp** and
+**−37.7 damage taken/run** at no detectable damage cost — but the **exact
+two-sided cross-opponent sign test is 10/13, p = 0.0923**, which does **not**
+clear the pre-registered p < 0.05 (leg 2 fails). Both legs were required, so
+**no default flip was made and no binary was rebuilt**. Refusing to ship when
+the pre-registered criterion fails is the task's own rule and is a **successful
+outcome**. The champion is confirmed as the best movement; it stays fully
+reachable as an explicit opt-in: **`TR_MOVEMENT=strafe`**.
+
+The full criterion, the confirmation tables (per-opponent, sign test, CI, MDE)
+and the ship decision follow directly below; the raw analyzer output is at the
+bottom of this file.

+## Final confirmation + SHIP
+
+> **Provenance.** The ship criterion below was pre-registered and committed in
+> `ff03e81` *before* the confirmation battles ran; that commit is the frozen
+> binary's source (`ff03e81591fc…`, binary sha256 `4757a734f3b0…`). Session
+> `/tmp/ab/j120_final`, arms file `tools/ab/arms_movement_final.txt`, frozen
+> panel `tools/ab/panel_movement.txt`, **3 arms × 15 opponents × 5 runs × 3
+> rounds = 225 battles**, conc 6, `--reference tfil`; **0 invalid runs, 0 failed
+> starts**. Power is higher than every previous batch (5 runs/arm vs 3).
+
+**THE PRE-REGISTERED SHIP CRITERION (fixed before fighting).** Ship the flip of
+`TR_MOVEMENT`'s default from `tfil` to `strafe` **only if**, on this frozen
+panel and one frozen binary, `strafe` beats `tfil` head-to-head on round wins/run
+with **both**: (1) the 95% CI on Δwins/run **excluding 0**; **and** (2) the
+cross-opponent **sign test favouring `strafe` at p < 0.05** (the campaign's
+standing convention, two-sided exact binomial).
+
+**SHIP DECISION: NO — the gate failed on the sign-test leg.** (MEASURED)
+
+| leg | test | result | verdict |
+|---|---|---|---|
+| 1 | 95% CI on Δwins/run (`strafe` − `tfil`) | **+0.33, 95% CI [+0.08, +0.58]** — excludes 0 | **PASS** |
+| 2 | cross-opponent sign test (exact, two-sided) | **10/13 decisive opponents, p = 0.0923** | **FAIL** (p > 0.05) |
+
+Both legs were required, so **the default was NOT flipped and the shipped binary
+was NOT rebuilt** — `TR_MOVEMENT` still defaults to `tfil`. Per Task 1's own
+rule, refusing to ship when the criterion fails is a successful outcome.

+
+### Reading (MEASURED / INFERRED)
+
+* **MEASURED — the champion is confirmed on effect size and mechanism.**
+  `strafe` wins **+0.33 wins/run** over `tfil` (CI [+0.08, +0.58]); the
+  incoming hit rate is down **−4.75 pp** (CI [−6.64, −2.86]; 1/15 opponents
+  favour `tfil`) and **−37.7 damage taken/run** (CI [−55.50, −19.97]) at a
+  damage cost of −7.85/run, **inside the MDE (11.81) so not detectable**. This
+  is the **fifth independent session** to show the same survival win (previous
+  four: 53.0% vs 42.2%, 52.6% vs 38.5%, and Batches 1–2's +0.33…+0.58).
+* **MEASURED — the gate is a sign-test near-miss, not a contradiction.** Ten of
+  thirteen decisive opponents favour `strafe`; two ties (Diamond, SpinBot — both
+  ≈0 wins/run for `tfil`) and three **exactly −0.20** opponents (DrussGT,
+  WallAvoider, DiamondStealer — each −1 round out of 15) leave the exact
+  binomial at p = 0.0923. The **sign-flip permutation (p = 0.0178)** and
+  **Wilcoxon (p = 0.0189)** — the campaign's other two cross-opponent tests —
+  both clear 0.05; only the exact sign test does not. I did **not** move the
+  pre-registered goalpost: the gate as committed required the sign test, so the
+  ship did not happen.
+* **MEASURED — the challenger nominally out-scored the champion in this
+  session.** `wide_spread` posted the session's best wins/run (+0.51, CI
+  [+0.16, +0.85], sign test 10/12 p = 0.0386) and was damage-neutral (−2.08,
+  inside its MDE). In Batches 3–4 it was a tie (+0.11, p = 0.55). **INFERRED:**
+  the two arms are **not separable** head-to-head in this design (both sit
+  ~+0.3…+0.5 over `tfil`); the confirmation does not install `wide_spread` as a
+  better champion — it merely fails to separate it.
+* **MEASURED — `tfil` is the worst of the three on both primaries**: 40.4% round
+  wins vs 51.6% (`strafe`) and 57.3% (`wide_spread`), and the highest incoming
+  hit rate (17.40%). The direction of the whole campaign is unchanged.
+
+### What the default is now, and how to use/revert it
+
+**The default is `TR_MOVEMENT=tfil` — UNCHANGED.** No source line was edited and
+no binary was rebuilt, so the shipped `ModularBot_garage/out/ModularBot` is the
+same binary as before this job. (The single dispatch line that would flip the
+default is `ModularBot_garage/src/ModularBot.nim:118`:
+`let MovementName* = getEnv("TR_MOVEMENT", "tfil")…`.)
+
+To run the confirmed-best movement, opt in with an env-only switch (both engines
+are always compiled in, so no rebuild is needed):
+
+```sh
+TR_MOVEMENT=strafe
+```
+
+`tfil` remains the default and is a one-word revert (`TR_MOVEMENT=tfil`); an
+unrecognised value still falls back to `tfil`.
+
+### Honest limits (what this design space did NOT cover)
+
+* **The failed gate is a discrete sign test on 15 opponents.** At n = 13
+  decisive, 10/13 is one opponent short of the 11/13 needed for two-sided
+  p < 0.05; the effect (51.6% vs 40.4% round-win rate) and its CI are
+  unambiguous. Settling the sign test would need a **pre-registered larger
+  panel** — adding opponents now would start a new panel and re-open every prior
+  verdict, so it was not done.
+* **The confirmation could not resolve `strafe` vs `wide_spread`** (+0.18
+  wins/run apart, overlapping CIs).
+* **Scope:** 1v1, 800×600, these 15 opponents. Nothing here is evidence about
+  melee (a different game — see j116), the twins/smaller arena, or opponents
+  harder than this panel.
+* **Local optimum:** the strafe retune is the measured optimum only *of the knobs
+  that were swept* (reversal dwell, spread/reach, heat strength, wall geometry).
+  A structurally different mover (wave surfer, learned policy) is untested.
+* **Round wins here are survival wins.** The measured advantage is "takes fewer,
+  weaker hits and survives more rounds at unchanged damage output", not "kills
+  faster"; it need not transfer to an opponent that wins on damage.
+
+**Pre-registered prediction — WRONG, recorded as wrong.** I predicted `strafe`
+would pass both legs and ship, and that `wide_spread` would tie it. `strafe`
+passed leg 1 but **failed leg 2** (p = 0.0923), so the ship prediction is wrong;
+`wide_spread` was nominally *above* `strafe` (+0.51 vs +0.33), wrong in
+direction though correct that no separation exists.

+### MEASURED: cross-opponent aggregation (the verdict layer)
+
+Deltas are per-opponent (arm − reference). `spread` is the SD of those deltas ACROSS opponents; `SE` = spread/√n; `95% CI` = mean ± t·SE. Sign test = how many opponents the arm wins (ties dropped), exact binomial; sign-flip = permutation test on the mean of the deltas.

+### The pre-registered verdict (rules fixed in `docs/movement_campaign.md`)
+
+PRIMARY metrics are dmg/run and wins/run; hit rate is never the verdict. The pre-registered rule says an arm is BETTER when one primary metric is UP at sign-test p<0.05 `while the other does not go down`. That phrase has two readings and BOTH are printed:
+
+* **strict** — the other metric's mean delta is not negative at all (`Δ >= 0`). Nothing can be BETTER while it costs *any* mean damage.
+* **substantive** — the other metric's delta is not *detectably* down: the sign test is not significant **and** the delta is smaller than that metric's MDE (the pre-registered rule 3 says an effect under the MDE is not detectable, so it cannot count as a loss).
+
+| rank | arm | Δwins/run | Δdmg/run | sign test wins | sign test dmg | verdict (strict) | verdict (substantive) |
