The owner: choose the tile pool not only from the heat point but from the
geometric position too. Heat stays the hard filter; the draw over the
survivors is re-weighted by turn and/or distance. Three weighting forms
(soft softmax / top-K third / rejection band), one env name carrying both
axes. Default = off = today's uniform draw, byte-for-byte (golden parity).
WHAT DIFFERS FROM j9 (TR_TFIL_TURN_BIAS, a live null): that was a tiebreak
weight among the non-empty safe set only. This runs on the WHOLE pool the
draw already runs on, including the 2 promoted least-hot tiles the ~65%
forced picks choose from.
OFFLINE (8 fixtures x 3 seeds, no java): headline 'tile actually reached at
tta' 4.5% -> 16.9% at TR_TFIL_GEO_MODE=both-soft TR_TFIL_GEO_TAU=45, with
no diversity collapse (distinct tiles 220 -> 219, normalised entropy
0.87 -> 0.86, top-tile share 7.0% -> 8.6%). perpE — the perpendicular rate
in the FORCED population — does not move in ANY arm: that pool is 2 tiles
ranked by heat alone and the only lever is a coin flip.
Also registers j150's TR_TFIL_DIAG / TR_TFIL_DANGER_THRESHOLD in
env_report + knownEnvNames + .env.example (test_env_report was red) and
documents DANGER_THRESHOLD as quantisation-limited: heat comes in 5s, so
the effective steps are 10/15/20 and 10-14 admits zero extra tiles.
No battle, no server, no A/B run.
Measures the owner's two complaints per pick (turn angle, heat on the path
vs at the destination, time-to-arrive, and whether the destination is hot on
the recorded true future when we would arrive), split by empty vs non-empty
safe set. Result: the path IS scored (hard filter + least-hot fallback), but
there was NO time term at all -- 65% of picks outran the 15-tick commitment
and the chosen tile was reached 6.5% of the time. The bound refuses a
candidate we cannot reach in TR_TFIL_ARRIVE_TICKS (default 0 = off = today).
