AetherDriveData and AetherDrive, Union(12) (now a retired-do-not-reuse comment, as 26 is),
HardpointType.AetherDrive (last member, nothing shifts), Ship's drive sets, aggregates and
Axis write, the five request-field rows, GameplaySettings Aether multipliers, ShipInstance's
drive particles, SchematicDisplay's RPM display and AetherDriveUi, the undock refusal's drive
clause, the drive prefab and material, and AetherDb's drive roles and brownout row. The
design is kept at parked/aether-drive.
Adds EveryShippedShipHullHasATopSpeed. ARPG.unity still holds stale serialized references to
the removed SchematicDisplay fields and the RPM Display object; the next commit removes them.

- Entity.Target is one slot of TargetRef, read-only from outside
(IReadOnlyReactiveProperty); Entity.SetTarget is its one writer. A chunk is
taken only while the entity can see it, so a rock in darkness cannot be
picked. Every handler, agent, turret and test writes through SetTarget.
- Entity.ChunkInfo (Q14 A): the value the per-tick sensor rule settles at,
computed on demand through Sensor.PassiveRate/Sensor.Gain -- sum of the
active sensors' passive rates over (sensors x TargetInfoDecay), capped at 1.
Stored nowhere; no per-tick loop over chunks. ChunkVisible is the detection
threshold through the chunk path.
- The lost-track rule reads through the chunk path: Activate's reconciliation
and a per-tick check of the one slot drop a chunk target that has gone dark.
- Entity.VisibleChunksInReach (Q13 A): visible chunks within the longest range
among active weapons -- the one reach rule for cycling and programmatic picks.
- Entity-only readers take .Entity: TargetedBy/TargetedByCount, target items,
the stance gate (a chunk has no stance), lock (Q12 A: never on a chunk),
turrets, Combat, Minion, FireControl (a chunk fires untargeted until Cut 4).
TargetRange and the arc gate read a chunk's planar position.
- ActionGameManager: the reticle and next/previous offer visible ships and
visible chunks in reach; nearest stays enemies-only; the target panel,
indicator and fire-control debug take TargetRef. EntityInstance reads .Entity.
- MiningCut3Tests pin parity, darkness, monotone brightness, wear and break,
reach, the chunk query, target survival and loss, TargetRef equality, lock,
and field-kind assignment at generation and first load.

LaneAndSilhouetteAllocateNothingGivenAPooledBuffer failed in 1 of 12 full-suite
runs (1232 bytes over 1000 Lane calls) and in 0 of 100 runs of the test alone
or its class. The allocation is a one-off, not a per-call cost: under suite
load the runtime's background tier-up is delayed by other tests' JIT activity,
so first-use allocation lands inside the single measured window.
The rule stays: Lane and buffered Silhouette allocate nothing. The test now
measures up to 20 rounds of 1000 calls and requires the smallest round to be
zero. A per-call allocation appears in every round and still fails it.

The previous AlongBearingReturnsTheExactSlabIntersection wrote out SlabAxis's
own threshold (1e-9f) and clamp a second time in its ExactSlab helper, so a
mutant that only moved that threshold (C7b, 1e-9 to .2) agreed with both
copies identically and survived.
AlongBearingReturnsTheExactSlabIntersectionAtSeveralBearings replaces it: the
expected entry/exit now come from an exact ray-box intersection that never
special-cases a near-zero bearing component -- IEEE division by a signed zero
already yields the correctly signed infinity, so an axis with no motion is
unconstrained without a hand-written epsilon to disagree with SlabAxis's own.
Checked at the original fixture's bearing plus two within about 11 degrees of
an axis, inside C7b's mutated .2f threshold but nowhere near the real 1e-9f
one.

Items carried into 12.3's brief from 12.2's third Soul pass, all on code
12.3's own lane walk builds on:
- LaneSeamIsHalfOpen pins the s >= Hi admission test (FireControl.cs) on
the smallest fixture where the seam matters -- the s > Hi mutant that
survived 12.2 would have interleaved two columns at a shared seam once
12.3's walk started reading more than buffer[0].
- AlongBearingReturnsTheExactSlabIntersection gives AlongBearing/SlabAxis
their first test of actual VALUES (every mutant there survived in 12.2,
equivalent while only buffer[0].Cell was read) -- a diagonal fixture
checks Lane's own Entry/Exit against an independent slab solve, cell for
cell, in order.
- Corrected the allocation comments on Forecast and
LaneAndSilhouetteAllocateNothingGivenAPooledBuffer: the ~120 B/call on a
gated-in HitProbability is three GetBehavior<TargetingSystem> calls (not
EquippedItem.Behaviors, which is a plain array), plus CellsOf's ~944 B
when an item is aimed at; noted that the loose <500_000 bound doesn't
catch a reintroduced comparer wrapper but the buffered zero-allocation
asserts do.
- ZeroProbabilityShotCommitsAMissWithoutBuildingASilhouette is now
behavioural: PFire 0 comes from closing VisibleEntities (the real gate),
and "no Silhouette was built" is checked by asserting zero allocation
rather than reading CommitProbability's own struct default.
- Dropped the unused System.Reflection import.
Also replaces ExpectedMarchCells, which reproduced Entity.ApplyHit's own
deleted 0.5-step march, with ExpectedLaneCells, built on the
already-verified FireControl.Lane plus an independent penetration cutoff --
used by TurningAfterCommitChangesNothing, whose fixture also gets real
per-cell armour (the flat 1000 armour every Build() authors would let the
new sequential Absorb model's first cell alone swallow the whole 5-damage
shot, leaving nothing to show on the rest of a several-cell lane).

Measured (Release, 7x9 solid hull -- the LonginusX shipped-hull fixture the
brief named is not available to this test file):
- Lane: 0 B / 1000 calls (was: 64 B/call from Array.Sort's comparer wrapper;
now confirmed 0 after the earlier IComparable<T> change in this batch).
- Silhouette (caller-supplied buffer): 0 B / 1000 calls.
- HitProbability, gated in (a real, non-gated-out call): ~120 B/call. This is
NOT from Lane, Silhouette or the comparer -- it comes from Accuracy/
Resolution's own GetBehavior<T>, which walks Entity.Equipment and each
item's Behaviors (both ReactiveCollection<T>); that type's enumerator is
heap-allocated per foreach. This predates Cut 12.2 and is out of this cut's
scope to fix.
- Inspect, gated in: ~280 B/call (same cause, more GetBehavior<T> calls).
The Forecast comment claiming "the forecast path (HitProbability, Inspect) no
longer allocates on a gated-in call" was not true and is corrected to say what
was actually measured: Silhouette itself is allocation-free given a pooled
buffer, and the residual cost belongs to Entity's own collection choice.
LaneAndSilhouetteAllocateNothingGivenAPooledBuffer asserts the true zero-alloc
claims exactly and records (with a loose regression bound, not a false zero)
the unrelated Entity-level cost on the full HitProbability path.

CommitProbability's `if (p <= 0f) return 0f;` guards against building a
Silhouette for a shot that cannot hit. Stryker's `p < 0` boundary mutant
(excluding only p == 0 exactly) survived because nothing exercised the guard
at that exact boundary. ZeroProbabilityShotCommitsAMissWithoutBuildingA
Silhouette sets a real, fired shot's PFire to 0, calls CommitProbability
directly and asserts sil stays the zeroed default (Intervals null, Count 0 --
no Silhouette was built), then resolves the shot through Zone.Update and
checks it lands as a clean miss.
Manually verified against the exact `p < 0` patch: it now fails (sil.Intervals
comes back non-null, a real Silhouette array).

Only a 2x2 (BigMarker) aimed item was ever tested -- a square's centroid and
its bounding-box centre are the same point, so N11 (aim point = bounding-box
centre instead of the true cell-average centroid) survived. AimingAtAnLShaped
ItemCentresOnItsCentroidNotItsBoundingBox equips a 3-cell L-tromino (Build's
new equipLMarker fixture), fires from a diagonal facing so the shape's true
asymmetry projects fully onto the lateral axis, and asserts the empirical mean
lateral offset tracks the item's own true centroid (computed by the test) and
not its bounding-box centre.
Manually verified against N11's own patch: it now fails (empirical -2.139,
tracking the wrong bounding-box prediction -2.121, against the true centroid
-1.886); the existing BigMarker test is unaffected since a square's two
candidate points coincide.

TheHudEstimateIsTheCommitPrice used to fire each shot, then reach into
Zone.PendingShots and overwrite the frozen Tracking field after the fact. Build
now takes a `tracking` parameter (default 100000, matching the old fixed
value) alongside Precision and Accuracy, so this test authors Tracking = 6 up
front like every other frozen shooter stat, with no post-hoc patch loop.
Manually verified M15 (Commit applies PSpread twice) still fails this test
(empirical 0.070 vs forecast 0.126) after the rewrite.

F8 (Soul's earlier fix batch, 2026-09-24) moved range computation ahead of the
visibility gate in FireControl.PFire so Fire's own flight time stays real even
when the shot prices at PFire 0, but no test observed that behaviour --
N4 (Soul's own mutation set, reverting F8) survived every existing test.
InvisibleTargetStillResolvesAtItsRealFlightTime fires at a target removed from
VisibleEntities and checks the shot does not resolve before its real 5s
arrival (N4's bug would resolve it instantly, at range 0) and resolves as a
miss once it does.
Manually verified against the exact N4 patch: it now fails (arrival at ~1s
instead of ~6s, i.e. range treated as 0).

TwoProngHullSplitsTheScatterAcrossBothIntervals's own within-prong check
(atNearColumn > atFarColumn) held under M12/M12b (an entire second silhouette
built at the wrong sigma) and the sigma/sqrt(2) Stryker mutants, because every
wrong sigma tried still puts more mass on the nearer column -- direction alone
cannot separate a sigma of 1.5 from 1.5*sqrt(2). Their analytic near/far mass
ratios are well apart (~2.9 true vs ~1.73 at sigma*sqrt(2)), so the test now
computes the true ratio from the same per-cell Gaussian integral it already
uses and asserts the empirical ratio (8000 shots) tracks it within a tolerance
that rejects the wrong-sigma ratio.
Manually verified against the exact M12 and M12b patches from Soul's mutation
script: both now fail this test (empirical ratios 581 and 1.68, matching a
collapsed and a sqrt(2)-shifted sigma respectively, against the analytic ~2.9).

Replaces LateralDrawIsHalfOpenAtTheShadowsTopEdge (reflection into the private
LateralDraw) with:
- ShotAtBearingLoTouchingOnlyACellCornerHitsMetal and
ShotAtBearingLoOnTurningArmourHitsMetal, Soul's two named-seed crash repros
(Cut12-edge-68442709 and Cut12-edge-64078070 -- StableHash(zone name) seeds
Zone.CombatSeed, so the exact name reproduces the exact die roll) run
through the real public Fire/Zone.Update path, asserting the shot commits a
hit whose cell's own projected lateral interval contains the drawn Lateral,
instead of throwing.
- LaneNeverEmptiesAtAnIntervalEdge, the general sweep: every interval's Lo and
the point just below its own half-open Hi, across several bearings,
precisions and hulls (including a non-convex, holed one), must never return
an empty lane from FireControl.Lane.
Build gained a zoneName parameter (Cut 6.1's one-fixed-name convention doesn't
serve a repro that needs an exact CombatSeed) and a tracking parameter and an
equipLMarker fixture, both used by later findings in this batch.

F1 (correctness): LateralDraw clamped the drawn lateral to the closed
[Lo, Hi], not the spec's half-open [Lo, Hi). Soul enumerated all 2^24
NextFloat outputs against TurningArmourIntoTheShotTakesItOnTheArmour's own
geometry and found 3 that draw exactly Hi, which Lane's own half-open filter
then admits no cell for -- a hit that passed its roll landing nowhere (R3).
Fixed the clamp; Lane's silent int2.zero fallback on an empty lane is now a
thrown InvalidOperationException, since an empty lane is provably impossible
after the fix. Committed Soul's edge probe as
LateralDrawIsHalfOpenAtTheShadowsTopEdge.
F6/F8: HitProbability, Inspect and Fire each assembled bearing -> Silhouette
-> PSpread (or recomputed range) in their own copy; a shooter-frame bearing
bug in HitProbability's copy survived while the identical bug in Inspect's
copy was caught. Collapsed into one Forecast function and one PFire(out range)
overload; both callers, and Fire, read the one computation.
F2: FireControlCut12Tests' zone names carried a Guid, breaking every other
cut's fixed-seed convention (FireControlCut6Tests.cs:62-63) and reseeding the
die every run -- the actual source of the flake in
TurningArmourIntoTheShotTakesItOnTheArmour. Fixed to a fixed zone name.
F3/F4/F5/F7: added a two-prong hull fixture (LateralDraw's walk past the first
interval, and a wrong-sigma placement, were unreachable when every fixture
projects to one interval), a real-roll empirical test for CommitProbability
(the old one called the pure function twice and compared it to itself),
enough Penetration in TurningAfterCommitChangesNothing for ApplyHit to
actually read the bearing, and a 2x2 item fixture for ResolveAimPoint's
average (every "Marker" elsewhere is 1x1, so sum/length and sum*length agree).
F9: Lane's own comment claimed no allocation while its sort used
Comparer<T>.Create over a closure; LaneCell now carries its own precomputed
projection and Lane sorts with a stateless singleton comparer. Corrected an
overclaiming comment in FireAuthorityTests (SigmaFloor makes the aimed-lane
draw ~68% per shot, not deterministic; the fixture's fixed zone name is what
actually makes it reproduce).
Cost: Silhouette takes an optional caller-rented Interval[] buffer; the
forecast path (HitProbability/Inspect, via Forecast) rents from
ArrayPool<Interval>.Shared and returns it before returning, since neither
reads sil.Intervals after the call. Commit/CommitProbability still get an
owned array, since LateralDraw needs it alive past the call. Measured on
LonginusX (66 cells, Release): unaimed 672 B -> 184 B/call (1512-1637ns before,
1482-1560ns after); aimed 1160 B -> 672 B/call (2123-2140ns before,
2094-2162ns after) -- the remaining ~488B/call gap between aimed and unaimed
is ResolveAimPoint's own CellsOf allocation (a List<int2>+ToArray per call),
not in this batch's scope.

The first Stryker pass (375 mutants, 69 survivors on this cut's own changed
lines) found one real split-authority bug and several untested edges:
- HitProbability recomputed target.Position - source.Position a second time
for PSpread's range, a second place the same subtraction could flip sign.
PFire now returns its own gate-computed range by out parameter; HitProbability
reads that one value instead of a second copy.
- TravelDirection's point-blank fallback and Fire's null-target guard around it
were only ever exercised at shooter/target pairs where the real direction
happened to equal the (0,1) fallback by coincidence.
- diagnostic.PFire (presentation) was only ever checked at PSensor == 1, where
Accuracy * PSensor and Accuracy / PSensor agree.
- CommitProbability's four-factor product was only ever checked with
pDeviation == 1 (no fixture moved a target between fire and commit), where
* and / by 1 agree.
- ResolveAimPoint's zero-cells fallback (an aimed item that no longer occupies
any cell) was never reached; every fixture's marker survives to be hit.
New tests: TravelDirectionMatchesThePredictedInterceptAndFallsBackAtPointBlank,
DiagnosticPFireIsAccuracyTimesPSensor, CommitProbabilityIsTheExactProductOfItsFourFactors,
AimPointFallsBackWhenTheAimedItemNoLongerOccupiesAnyCell.

FireControl.Silhouette replaces HullKernel/WeightedPick/POnHull: the hull's
lateral shadow at a bearing, merged into intervals, integrated exactly with
CultMath.erf/erfinv instead of a discrete per-cell Gaussian sum. FireControl.Lane
does exact slab traversal to pick the impact cell from a lateral offset; only
its first element (the entry-nearest occupied cell) is used here, per the cut
map -- the rest is 12.3's armour-first absorption march.
Bearing timing: PendingShot.PBase is renamed PFire and now carries only the
shooter-side factor (Accuracy x PSensor) behind the gates; TravelDirection,
Spread and FireRange are frozen alongside it. The target's facing is read live
at Commit through FireControl.CommitProbability (steps 1-5 of the spec's
"Bearing timing"), not frozen at Fire, so a target that turns its armour into
an incoming shot takes the hit there. ShotOutcome gains Bearing/Lateral,
frozen at commit; Apply reads only those, never a live position or facing.
Entity.ApplyHit takes an already-schematic bearing instead of a world
direction, and the ToSchematic call 12.1 put inside it is gone.
Superseded tests: PlacementAndProbabilityShareOneKernel, EveryHitLandsOnMetal
and AimingAtTheSternHitsTheStern are replaced by
FireControlCut12Tests.PlacementAndProbabilityShareOneSilhouette,
HitsLandOnTheFacingEdge and AimingAtAnItemCentresTheScatterOnItsLane.
FireAuthorityTests.AimedHitLandsOnSelectedItem and PenetrationMarchIsPlanar are
updated for ApplyHit's new bearing parameter and Lane's entry-nearest-cell
placement (a solid hull's Tool item is never itself the entry cell; reaching
it now needs the same penetration march the new tests exercise).
