examples/roster_target.rs ranks stages by how many roster units are still
unharvested. The EnumUnit_S<NN> tables are found by hashing candidate TOC paths
(hash::TOC_NAME_SCHEMES) — UnitRoster::stage can only infer a tag when the roster
carries a UN_S<NN>_ prop, which most do not.
It picked S09 (10 missing). Flying it: 26 -> 36 units, 3 345 -> 4 785 rows,
2 351 -> 3 439 defaulted-on-disc values. New: e102_Battleship, e104_Carrier,
e107_AAFrigate, e011_Attacker_B, e008_TurretPlus, be001_TerrafoamingUnit,
e001_Elan_GR{,_Violeta}, f102_LightCarrier_Inv, f106_Destroyer_Inv.
Also settled: the definition objects are mission-independent. Eleven units appear in
more than one snapshot and four are not byte-identical, but compared through the
layout ZERO mapped fields differ — the 12 differing slots are all unmapped (offsets
4/8/16/20 and 0x250/0x268/0x300-0x308/0x330-0x338: object header and sub-object
pointers). So a harvested value is the definition, not a per-mission tweak, and the
earlier UN_f201_TCAF_Tanker flag resolves the same way. Cross-checks over three
snapshots: 1 052 agree, 0 disagree.
Third angle field found the same way (Through_AngleMaximum = 60 degrees in radians),
so the degrees<->radians rule covers any name containing "Angle".

examples/why_missed.rs reports the furthest gate per undecoded resource. Disc-wide
that is 47 rows / 43 distinct names, and they are mostly not ship geometry:
30 e_rou_/_rou_ pose & proxy composites (24-vertex marker boxes, extent 0.010)
6 .DAT particle composites in ptc_pack
8 damage/LOD variants (e101_bdy_02_d, e901_wing_05_*_m, ...)
3 props/other (g005 extent 0.196, _rou_f001_wep_05, e_rou_e005)
By gate: extent 32, coverage 8, winding 7. The extent bucket is almost entirely the
pose-proxy boxes, and lowering that floor was measured and refuted earlier. The one
genuinely interesting residual is e901_wing_05_L/R at winding 0.587/0.570 against the
0.70 floor — the signature of a thin double-sided sheet, unproven without a capture
with the boss on screen (flying stage 16 puts the container in memory but the unit
never appeared).
So: 6 247 / 6 294 resources decode (99.25 %), and every real mesh drawn in three
captured missions decodes at the GPU's own offsets with index runs matching byte for
byte (93/93 and 128/128).

desc_dump shows each index marker is followed by its OWN element triples: n201_01
declares strides 24, 24, 24 and 28 (the last sub-mesh has a fourth element), which
matches the runtime capture's stride=28 on that draw and the four distinct vertex
shaders. parse_vertex_decl read the first declaration for the whole pool.
all_vertex_decls reads one per marker; anchor_grouped_meshes uses each sub-mesh's
own stride for the pool walk, the pivot validation and the read. debug_grouped_report
follows the same setting so the diagnostic cannot blame the wrong gate — at n201_01's
capture-proven pool start it now reports "pad 0: ACCEPTED" instead of a NaN position.
With XBG7_SUBMESH_DECLS=1: resources that never decode 85 -> 47, resources decoding
in no container 63 -> 30, capture oracles unchanged (93/93 index runs, 42/42 index
counts), consistency unchanged at 96.
Off by default because selection has not caught up: the three n201_0x copies then
settle on one pool (twin_pairs_do_not_share_a_buffer fails), production still picks
a start 4 bytes before sub-mesh #1 rather than the proven one even though the proven
start validates and is unclaimed, and four newly decoded ptc_pack .dat composites
carry degenerate triangles. Format truth is settled; choosing among candidates is
the remaining work.

capture_ib_truth now proposes an identity for each drawn buffer our decoder cannot
place, by matching (vertex, index) counts against declared-but-not-decoded
resources. That identified n201_01/_02/_03 in Stage_S02.xpr — three of the 63
resources that decode in no container — and the capture pins all four sub-meshes:
#0 vb 0x32BA71C ib 0x32B39FC 4464 idx 777 v stride 24
#1 vb 0x32BEFF4 ib 0x32B5CDC 4464 idx 869 v stride 24
#2 vb 0x32C416C ib 0x32B7FBC 576 idx 192 v stride 24
#3 vb 0x32C536C ib 0x32B843C 4464 idx 869 v stride 28 <- different
The layout matches our assumptions exactly (tight index packing, last buffer flush
against vb0 so pad 0, span 27936 == align4-summed markers, contiguous vertex
buffers, max index == verts-1 everywhere). The defect is that sub-mesh #3 has a
different stride AND its own vertex shader: anchor_grouped_meshes parses one
declaration per resource and applies its stride to every sub-mesh, so it reads #3
out of phase (372 non-finite position components of 2607), and since the pivot is
the largest index count with ties going to the last marker, the pivot IS that
sub-mesh — so the whole resource is declined.
Also adds examples/miss_targets.rs (which container to aim a capture at): 63
resources decode nowhere, 58 of them in exactly one container, clustering as
Stage_S16 21 (e901_wing_05_*), ptc_pack 12, Base 6, then per-stage n2xx groups.
Flying stage 16 did not draw the e901 wings — the container is resident but the
unit must also be on screen.

Two follow-ups to the pad-scoring fix, both driven by the same invariant (a
correctly located index run has no degenerate triangles):
- anchor_grouped_meshes picked its pad by first-match too; scoring the pivot run
the same way cleared every remaining ptc_pack composite (f102/f104/e107).
- anchor_pool_mesh now prefers a degenerate-free candidate over an earlier dirty
one. examples/better_home.rs showed the last two resources each had exactly one
degenerate-free, pool-covering block, sitting later in file order than the
lookalike we took. First-match order is kept for every clean hit, and a dirty
block is still used if nothing clean exists, so coverage cannot regress.
degenerate index runs, disc-wide: 582 -> 11 -> 1
captured index runs identical: 93/93 (unchanged)
resources decoded / misses: 6 209 / 85 (unchanged)
index runs changed / anchors moved: 590 / 10 (_rou_f402_dead x8, e201_bdy_03_m x2)
Cross-container minority decodes 89 -> 96, and that is progress: all seven new
rows are _rou_f402_dead, which now has a majority (32x25x8) for the first time, so
its seven wrong copies are named instead of hidden behind "no majority".
The last dirty run (_rou_f402_dead in Stage_S09) is blocked by distinct assignment
— its clean block is claimed by e_rou_f003_Near, both 24-vertex bounding boxes. A
winding-floor escalation for that case was written, measured to fire for nothing,
and reverted; the reasoning is kept as a comment.
Regression threshold tightened to 1. Suite green with --include-ignored apart from
the pre-existing known-failing cross-container consistency test.

Extending the capture comparison from index COUNTS to index VALUES
(`examples/capture_index_bytes.rs`, using the batch offsets the new ib logging
gives) showed 76 of 93 Stage_S02 index runs identical to the GPU's and 17
differing — every difference a shift by exactly one element, on buffers whose
index data sits at pad 2.
`anchor_pool_mesh` returned the FIRST pad that validated, and pad 0 is tried
first with the looser winding gate (0.70 vs 0.85). Read at pad 0, a pad-2 block
yields [true[1], true[2], …, garbage]: every index in range, the pool covered,
the positions right, the winding often just above 0.70 — so it validated, and
every triangle was mis-wired. Nothing count-based could see it.
The signature is decidable without the capture: a shifted run wires arbitrary
vertices, so triangles come out degenerate. 282 of 283 correctly anchored
Stage_S02 blocks have zero degenerate triangles, while the shifted readings carry
1–2 156. So score every validating pad by (degenerate triangles, then winding)
and keep the best. `XBG7_PAD_FIRST_MATCH=1` restores the old behaviour.
captured index runs identical: 76/93 -> 93/93 (2 025 elements)
decoded runs with a degenerate triangle: 579 -> 16 (disc-wide)
sub-meshes whose index run changed: 575 of 8 850
resources decoded / vertex anchors / consistency: unchanged (6 209 / same vb / 89)
Locked in by tests/mesh_disc.rs::decoded_index_runs_have_almost_no_degenerate_triangles.

The decoder's central unstated assumption — a block's index buffer sits
immediately before its vertex buffer (`vb - idx_count*2 - pad`, pad <= 3) — was
also the prime suspect for the residual anchor misses, since a capture-proven
`e106_eng_02_l` block was rejected outright. Measured it instead of assuming:
- extended the F10 ship capture to log each draw's index buffer (base, count,
min/max index) and to key its de-dup on the index range, so every draw batch
is recorded rather than only the first;
- `examples/capture_ib_truth.rs` places each drawn buffer in the container by its
dumped positions and scores the capture against our decode.
Stage_S02, 42 drawn buffers placed: our idx_count == the sum of the draw's index
batches for 42/42, the batch union covers the vertex pool exactly for 42/42, and
all 30 single-block cases sit at pad <= 3 (20 at pad 0, 10 at pad 2). The other
12 are grouped pools, where one index pool serves the whole group. So the layout
holds, the decoded index count is exact, and eng_02_l died on the connectivity
gate (since replaced by the winding gate) — not on index location. The shipped
exact-coverage rule is independently confirmed.
The recorded "capture indices=21 vs our 246" disagreement was an artefact of the
old de-dup key: 21 was the first of two batches, 21 + 225 = 246. Any conclusion
from a pre-2026-08-13 capture's `indices=` or `vbase - ibase` is about one batch,
not about the block.

Anchoring each key string to the first store AFTER the accessor call makes the
extraction exact: 159 fields, 125 of them floats, and verify_fieldmap now checks
every one against the live objects -- 154 agree with the disc, 0 disagree.
The last ten mismatches taught the rule: angle fields are degrees on disc and
RADIANS at runtime (AV_PitchPlus_Max 3.6 -> 0.0628319; MaximumBank_Normal 60 ->
1.0472), an exact conversion across every angle field and unit.
101 defaulted fields now have runtime values: angle limits default to 3.6 degrees,
afterburner/turn-attack fields to 0, FiringRange to 0 (matching the loader's miss
value), Size_Y to that unit's Size_X, and the ratio family is per-unit rather than
constant (HQRatio 0.2 or 1, DefencePoint 0.1 or 0.25, ...).
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The filler builds each key as addi r4, r30, -N with r30 = 0x82088f94, so every
store's field NAME is a string in the image. Pairing keys with the following stfs
gives the layout outright: Size_X/Y/Z at +48/52/56, HQRatio +88, ShieldRatio +92,
ThrusterRatio +96, resistances +116..132, Radar/FCS/FiringRange +672/676/680,
Attack/Defence points +692/696/700. verify_fieldmap.rs checks it against the live
dump: 62 fields agree with the disc, 0 disagree.
That yields the runtime value of each field for units whose record omits it --
HQRatio 0.2/1, ThrusterRatio 0.2/1, ShieldRatio 1, ResistanceToPlayer 1,
ResistanceToShell 0.1, ResistanceToExplosion 0.5, AttackVesselPoint 0.1,
AttackCraftPoint 0.1/0.5, DefencePoint 0.1/0.25, FiringRange 0, Size_Y = Size_X.
Recorded with the caveat that several show two values across units, so these are
per-unit runtime values rather than one global default.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
pool_window.rs shows the Destroyer's raw tokens: "200.0" "Size_X" "Size_Y"
"2000.0" "Size_Z" -- Size_Y is a bare key, so the 13 runtime values recovered
earlier are real defaults, not a reader artefact.
The filler reads each size field through sub_822FC5A8, which loads f31 from
0x8209fd28 = 0.0 at entry and returns it on a pool miss, then stores to +52.
Nothing else in the 15876-byte filler writes +52, so the definition leaves a
defaulted Size_Y at 0.0 and the runtime 200 is written later.
Two corrections: the +48/+52/+56 comparison block builds a size-class bitmask
against 1000.0 (constant 0x8209fd20), not a has-value mask; and both earlier
Size_Y derivation candidates are refuted (one is a conditional pick, the other
multiplies into a different struct).

Searched RAM for HP 25000 (200+ hits, too common), for the rare float
AttackVesselPoint 0.08 (64 hits, no window holds the unit's other values, one hit
is a code constant), and for the ID string itself (two copies, each pointed at
from -0x10, but the surrounding 256 words hold none of the numbers because that
region is the IDXD string pool where values are ASCII).
Hypothesis recorded as 🟡: IDXD is reflective and the engine likely reads values
from the pool by key on demand, caching only the per-frame ones -- which is
exactly what the 0x820af844 object contains at any dump depth. If so, a defaulted
field has no value anywhere in data and the default is applied by code at read
time, so Route B for the Ratio/Count family needs the read path or the static
DuckDB route, not more scanning. The 13 Size_Y values worked because Size_Y is
one of the cached fields.

Dumping 512 words instead of 96 finds exactly the same 4 of ~50 disc values, for
all five correlated units, so the rest of the record is not in this structure.
Also corrects the reason recorded last commit: get_f32 is NOT unreliable on
default-heavy records -- it resolves 46-57 numeric fields per unit, which is what
made the emptiness of the correlation measurable in the first place. The one
automated hit (YawDragFactor -> +0x0c) remains false: +0x0c holds the integer 2
as a denormal and collided with the float 2.0.
Next probe is a RAM-wide search for a unit-distinctive value, not a bigger window.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Anchoring on a unit whose disc record sets a field locates it in the live object:
Size_X/Y/Z (+0x30/34/38) and HP (+0x54) confirmed across five capital ships and
the player fighter; +0x74 (0.8) and +0x84 (0.97) are probable ThrusterRatio and
ResistanceParalyze but rest on a single anchoring unit; +0x40 varies per unit and
is unidentified.
live_offsets.rs automates the correlation and currently produces one hit which is
false -- YawDragFactor 2.0 collided with the integer 2 at +0x0c stored as a
denormal. Causes recorded: get_f32 is unreliable on default-heavy IDXD records
because the value-before-key pairing shifts, and 96 words only reaches +0x180
while RadarRange/FCSRange sit beyond it. Next run dumps 512 words.

Live definition objects carry no name, so identity comes from the values:
unit_signatures.rs prints (HP, Size_X/Y/Z) for every disc unit and vessel, and a
live object is the record whose known fields it reproduces. 7 of 14 match a disc
record outright; the other 7 match nothing because their records default a field
-- 18 of 23 vessel records are missing at least one, nearly always Size_Y.
Matching each single-default record against the live object that reproduces its
remaining fields resolves 13 values (Destroyer 200, Cruiser 600/700, ASFrigate
80, ADAN Destroyer 300, Acropolis 400, ISCMissile 300, plus _Inv/_EX variants).
Every one equals that unit's Size_X, so the engine's own parsed definitions
confirm the statically-derived inheritance rule.
Limits stated: variants share one live object, and the ...Ratio/...Count family
is not resolved -- their offsets in the live object are still unknown.

Filtering after the assignment made every subset query a full decode (~15s on a
50MB container). full_decode_cached memoises it per container -- fingerprint is
length plus three sampled 4KB windows, keyed with min_consistency, last four kept.
Decoding five ships from Stage_S02 in turn: 10.5s for the first, then 48us-1.4ms.
A stage now costs one decode rather than one per ship. Ten suites green, viewer

models_named pruned to the wanted set BEFORE distinct assignment, so collision
resolution saw a different resource population and returned different offsets:
27 of 356 resources in Stage_S02 decoded differently when asked for alone,
including real geometry (f001_bdy_30, f106_sld_02_l/m/d, f101_wep_01_l). Both the
viewer and assemble_ship decode subsets, so both could disagree with the
container's own answer. This was a regression from distinct assignment itself.
Fixed by filtering the OUTPUT: the assignment always runs over the whole
container. One-name, three-name and full decodes now agree exactly. Cost: a
single-resource query on a 50MB container goes from near-instant to ~15s;
per-container caching is the follow-up. Ten suites green.

Checking the vertex count of every minority decode: all 89 are 24-vertex
resources, including e101_wep_01_l, which last commit called the one real
geometry disagreement -- it is a 24-vert box too. So after this thread's fixes no
real mesh on the disc decodes differently in different containers; what remains
is structurally identical bounding boxes swapping identities, which needs an
ordering rule rather than a validity gate. Monotone anchoring was refuted before
but under a decoder with other defects, and is now cheap to judge: 89 -> 0.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
consensus_check names the minority container instead of just flagging
disagreement: 89 minority decodes across 477 resources with a majority, and 88
are scene composites. A composite's descriptor carries a 24-vertex bounding box
(e_rou_e106 -> 22x22x22, e_rou_f106 -> 745x718x718); those boxes look
interchangeable so the assignment shuffles per container. 1141 of 6209 decoded
resources have scene nodes. Counting only real geometry the disc has ONE
disagreement: e101_wep_01_l in Stage_S25.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Last iteration reported e303_wep_01 as inflated 30-110x by assemble_ship. Wrong:
the composite nodes carry scale 1.0 and orthonormal matrices, and under the
current decoder the turret places as 49x23x42 at +/-179. The 1600x2100x4800 box
only appears with XBG7_COVER_SLACK=4 -- the exact-coverage fix had already
repaired the turret too. The error came from comparing a deliberately pre-fix
render against post-fix measurements.
The containment screen's blindness therefore has a mundane cause: one mis-decode
inflated the envelope and hid another. Kept as a forward-looking invariant with
that caveat.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
envelope_screen measures per-axis protrusion past the sibling envelope, the
relationship the eye used. It still does not flag e106_bdy_03, and dumping the
static assembly shows why: e303_wep_01's world box is 1600x2100x4800 around a
~400x400x2000 hull, so nothing can protrude. The decode is innocent -- that
resource is 49x23x42 in every container -- so the static assembler is inflating
it 30-110x per axis, non-uniformly. The screen is only meaningful once placement
is trustworthy, and the assembler now has a worse defect than the decoder had.

Rendered f101/f105/f106/e105 statically -- all coherent, no stray masses, so the
e106 slab was specific. slab_screen.rs tries to automate the check by comparing
each part's min-axis extent to its ship median, but it produces identical flags
with and without the coverage fix at both 4x and 2.5x: it never sees
e106_bdy_03, the part it was built for. The eye used relationship (a mass apart
from the hull), not scale; a containment test is the right analogue and is not
built. Kept for what it does show: f002_bdy_22's 100000-unit tether and
t901_e01_D's mast are legitimate, and capture-verified f101_bdy_01 flags at 6x.

Rendering assembled e106 from Stage_S02 showed the old slab: e106_bdy_03 spanning
600x1600x998 where three other containers give 276x236x941. Its anchor had slack
3, and the coverage gate tolerated up to three unreferenced tail vertices --
tolerance that was hiding a mis-anchor, since real blocks reach their last vertex
exactly (8580 of 8629). Requiring exact coverage moves it to the block the other
containers agree on and the slab disappears.

biggest bucket turns out NOT to be the blocker: replacing the absolute area test
with a scale-free collinearity test decodes no more resources and raises
inconsistency 39 -> 44, and dropping the extent floor to 0.05 adds two. Both stay
as opt-in knobs (XBG7_REL_DEGEN, XBG7_MIN_EXTENT) rather than defaults. Also

The last two blocks that under-covered their vertex pool were f102_break.dat and
f104_break.dat in ptc_pack.xpr, each reading a neighbouring block's index buffer
against the wrong declaration (414 verts indexed to 404; 160 indexed to 79).
Their marker lists do not map onto the stored blocks -- only 2 of 9 and 4 of 10
sub-meshes decoded at all. Requiring coverage (max_idx + 4 >= vtx_count) for
pre-pivot sub-meshes drops exactly the mismatched pieces.
Every decoded sub-mesh disc-wide now covers its pool: 8580 at slack 0, 49 within

coverage_audit measures index coverage per decoded sub-mesh. 8586 of them
reference their last vertex exactly, so the 'buffer not covered' gate is well
founded -- but 18 had NEGATIVE slack: indices up to 364 vertices past the end of
their own buffer, emitted because anchor_grouped_meshes reads pre-pivot
sub-meshes unconditionally. Quality gates stay relaxed there (a tiny flat lead
part is legitimately poor) but index range is now required.

debug_grouped_report (why_rejected) shows n206_02's alternative pool is ACCEPTED

came from the audit comparing decoded geometry, and that offset holds a direct
(unmirrored) copy, so a separated pair still looked identical. The audit now

loser, so that pair is a validator case (like eng_02_l before the cap move), not
a selection one. Also fixes a stale '0.28 (default)' label in edge_cap_sweep.

twin_mirror_audit applies the capture-derived rule to all 166 containers: of 34
equal-count twin pairs, 18 are exact X-mirrors, 15 related another way, 1
identical, 0 unrelated. Two calibration fixes were needed first (authored halves
need a tolerance, and a mirrored pair may be stored in another vertex order).
The one collapse, n206_01/_02, is a grouped-pool pair -- the path distinct
assignment excludes -- so it names the next target. Added a disc-gated
regression test; refreshed the stale ignore message on the consistency test.

locate_draw counts copies of a captured buffer. The f105 parts _rou_f105_break
claims exist 3-6 times over (the 2336-vert one: 6 direct AND 6 mirrored), and
every live LOD checked is anchored on a direct, byte-identical copy -- so the
composite taking the drawn copy costs nothing. This also calibrates the oracle:
'exact' (anchored at the drawn offset) is stricter than correct, so 45/46 is a
lower bound. Open: a resource landing on a MIRRORED copy would be a real defect
invisible to every count-based metric.

capture_truth_scan places every drawn buffer across all 166 containers by modal
vbase-offset. Stage_S02 wins with 64 matches at one constant against Stage_S01's
16, and the logs carry f101/f105/f106/e105 -- a Stage-02 cast. Stage_S01 looked
consistent because the shared block is duplicated verbatim (twins 0x116F0 apart
in both), so the earlier structural findings hold; only the loaded-container
claim was wrong. The S02 table places 46 buffers, 12 claimed by nobody, and
resolves the six Stage_S01 mystery buffers as e105 parts.

XBG7_EDGE_CAP / XBG7_SMALL_TRIS make the threshold sweepable (defaults unchanged,
full suite green). Above 0.417 the capture-proven eng_02_l anchors exactly right
and no e106 part regresses, and nothing that decoded at 0.28 is lost -- but ~250
existing anchors move silently and 18 shared resources lose cross-container
consistency. Not changed: the movers have no oracle yet.

debug_find_index_buffer scans the container for an index buffer that validates
against a capture-proven vertex buffer. For eng_02_l nothing validates with the
connectivity test on; with it off the nearest hit is exact pad-0 adjacency
(vb-ib = 144 = 72*2). The block's mean_edge/diag is 0.417 against a 0.28 cap --
the documented false positive for coarse LODs, now caught with ground truth.

debug_try_anchor asks validate_block directly at the capture-proven offsets. Both
119-vert twin buffers are accepted by both twins (so the correct block lost the
first-match race, and a distinct assignment fixes it); the drawn 51-vert bridge
buffer is accepted by both bridge resources; eng_02_l's proven offset is rejected
outright, even with the pad widened to 64 -- a validator gap, not a selection one.

debug_vertex_run_starts exposes the anchor scan's candidate list: Stage_S01 has
15710 stride-24 starts and all three capture-proven offsets (0x3c55d8 twin,
0x40e418 bridge, 0x44a32c eng_02_l) are among them. anchor_pool_mesh takes the
first that validates, so an earlier lookalike wins. Scoped to the current
decoder's e106 cases; does not overturn the residual-51 finding.

The first read of the capture-truth table located our resources by searching the
container for their leading vertices, which reads much worse than reality: the
same leading run occurs at several offsets in one container. GameMesh now carries
the offset the anchor scan actually chose, so the comparison is exact -- 4 of the
ship's drawn buffers are anchored correctly, 2 are the twin collapse, and 2 are
real mis-anchors of a size we do decode (brg 51 verts, eng_02_l 44).

Locating each drawn buffer's positions inside Stage_S01.xpr shows vbase - offset
is one constant (0x1A94FFF4, same in two runs), so a capture gives ground truth
at file-offset granularity. Read against our anchor scan it is a defect list:
full/_m resources starting at their own _l buffer, eight drawn buffers claimed by
nobody, and the bdy_01_l/bdy_02_l twins sharing one buffer while the container
carries both halves (0x3b3ee8 and its exact X-mirror at 0x3c55d8).

texture_disc.rs and mesh_disc.rs fall back to "/home/fabi/RE Project Sylpheed/..."
when SYLPHEED_ISO / SYLPHEED_RES3D are unset. The directory is "RE - Project
Sylpheed"; the fallbacks were missing the " - ", so stage_models_decode,
stage_models_sweep and stage_models_quality_audit failed with NotFound for anyone
who did not happen to know the env var. They now pass unaided (10/10 in
mesh_disc).
Found while auditing what the suite actually exercises after withdrawing the
anchor change: an ISO-gated test skipping, and an ignored test failing on a typo,
are both "green" in a normal run.
Full state, with SYLPHEED_ISO/DISC/RES3D set and --include-ignored: 82 lib tests
and every disc/ISO suite pass; the single failure is
shared_resources_decode_identically_in_every_container, which is deliberately
written as the target state and #[ignore]d.

Dumping the remaining Arsenal components turned up placements reading as
4294966780 and 4294966856 -- negative as i32 (-516, -440). X and Y are signed;
off-screen animation starts are negative, and read as unsigned a reimplementation
would draw them four billion pixels off.
The raw region then showed the rest of it. The trailing word is a TIME, and a
group is an in -> hold -> out animation: prselect_win1 runs
t=4:-516 -> 6:-71 -> 7:81 -> 8:127 -> 23:134 -> 24:134 -> 25:127 -> 27:81 ->
31:-71 -> 1:-516. So NEITHER the first nor the last keyframe is where the element
sits -- both are off-screen. The resting position is the max-dwell keyframe,
(127,155)..(134,155) here, which is where the weapon-list panel actually appears.
This corrects my own note from earlier today, which reported "final=" positions.
Static elements were unaffected (the pause menu's buttons have identical
keyframes) but animated ones were misread. screen_layout.rs now reports the
max-dwell pose plus the full timeline, and both captures are regenerated.
Also seen while dumping: kind 0x2, and a .sbo child (scrollbar) parented to the
list window.

examples/screen_layout.rs dumps a bundle's declaration table and placement region
together. It reproduces the tutorial pause menu exactly and reads the ARSENAL the
same way -- 23 elements that match the running game: eight buttons prbtn1..8.rat
at X=242 evenly spaced (the config declares WEAPON_CATEGORIES = 8, and eight
categories are what the Arsenal shows), prexp3.t32 declared SEVEN times at X=726
34px apart (the DATA SHEET rows), prexp1 sliding (726,143)->(1286,143) with
prexp1a parented to it, and prmsg at (151,645).
Two additions to the format:
kind = 0x4 marks a REPEATED INSTANCE of a sprite -- prexp3.t32 appears once
with 0x0 then six times with 0x4, each with its own placement. So the element
name is not a key; the declaration index is.
A screen composes from named .prt components. GP_HANGAR_ARSENAL.pak has 510
RATC entries because its config names components (Menu = prmain_scr.prt, etc.)
and they resolve under the config's own PATH prefix: prmain_scr.prt is absent,
eng\prmain_scr.prt is present -- the same <lang>+<member> convention the movie
table uses. A sub-component reads identically: psselect_win1 declares 4
elements, three parented to element 0.

Tier 3 matched a part to its hardpoint by trailing index, so `e105_brg`
compared "01" == "" against GN_Bridge_01 and fell through silently. The runtime
capture is what exposed it: the game draws the bridge and places it at
[0, 70, -1850] rel e105_bdy_01, and assemble_ship emitted nothing there.
With no index to match on, take the lowest-numbered frame of the category.
Diffing assemble_ship part counts across every container: 34 (stage, ship)
entries gain parts — e102 +2 (bridge and engine), e104 +1, e105 +1, Stages
02-29. ship_audit is unchanged, so nothing regressed, and the capture now agrees
to dT 0.03 / dR 0.000.
Also fixes the diff itself: correlate_frames compared static against a rotation
sampled from the first block, which can belong to another INSTANCE of the class.
Scoped to the position-agreeing cluster, e105_eng_01 goes 1.711 -> 0.000 and
both e106 nacelles to 0.000. The one remaining rotation delta (e106_wep_02_01,
0.134) is a turret whose rotation varies by 0.182 between blocks that agree on
its position — the runtime disagrees with itself more than with the assembler.
The new rotVar column makes that distinction visible.

A capture at controlled range (ship_capture_close.sh: lock a capital ship, close
on it, F10 per range band) finally draws capital-ship hulls at full detail. Two
correctness fixes were needed before the numbers meant anything:
* one F10 log is ~14 frames with no delimiter, and WV_ref^-1 . WV_p only cancels
the camera within one frame — segment_frames splits on vertex-buffer
recurrence, and correlate_frames cross-checks the blocks against each other
instead of trusting a single shot;
* aggregate by consensus, not median: a stage holds several ships of one class
sharing vertex buffers, so a block can mix two instances.
Result: f105, e105 and e106 reproduce assemble_ship to <=0.43 units in
translation and 0.000 in rotation for every part that does not move. The e106
rules generalise, and the viewer bug report now points at the viewer. Narrow
leftovers: e105_brg is missing from assemble_ship, e105_eng_01 rotation differs
by 1.711.

Inverting the capture↔part question (invert_capture over one container,
vcount_index over all 166) identifies every large draw in the 2026-07-31
capture: the player's own DeltaSaber (10891 verts), its weapon packs, the
backdrop and particles. Of f101/e105/e106 only 1-3 of 15-37 resources have a
drawn vcount, each a 44-225-vertex far-LOD/effect piece whose count collides
with dozens of unrelated resources.
So the zero-correlation was not an LOD-list gap, not over-strict position
validation and not a different draw path: the ships were too far away to be
drawn. approach_capture.py flies at a locked capital ship and presses F10 per
range band, stamping each capture with its distance.

idxd_tokens took the sub-record type list as an argument already but still
hard-filtered entries to those declaring a `Weapon_*` id, so it could not be
pointed at another schema. Filter on the requested type names instead -- it now
splits `EnumUnit` (Generic/Maneuver/Shield/Explosion/Frame/Turret/...) too.
gmem: honour $GMEM_FILE. `cp --sparse=always /dev/shm/xenia_memory_* snap.bin`
takes ~2 s and reads identically, which matters because a running Canary pegs
every core under lavapipe and makes repeated live reads stall unpredictably.
Groundwork for the craft (UNIT) stats. Not a finding yet: in menus only the
player craft's *name* is resident -- the flight-model object is not instantiated
until a mission loads, so that needs an in-mission snapshot.

Canary backs the whole guest address space with one shared-memory file, so the
game's RAM is readable from the host while it runs -- no debugger, no emulator
patch. That turns the parked Route-B question (fields the IDXD omits because
they sit at their default) from "unreachable" into a table lookup.
gmem.py maps guest VAs into /dev/shm/xenia_memory_* via Xenia's fixed table and
searches only the allocated extents, so a full-RAM scan is ~0.2 s.
weapon_runtime.py finds the parsed objects by scanning for their vtable, then
*solves* the struct layout instead of guessing it: every (field, offset,
encoding) triple is scored against the disc records, and a binding is accepted
only with zero contradictions -- and marked confirmed only when >=10 records
agree on >=3 distinct values, because a field whose samples are all one number
matches any offset holding that constant.
Result: Weapon (0xc0) and Shell (0x200) mapped, 4393 values the disc does not
carry, for all 126 weapons at 5 % save progress. Cross-checks hold -- the
Arsenal DATA SHEET read 4 for wep_05/wep_60 Max. Lock Ons and the memory read
agrees; the in-flight HUD's 06000/00300 match LoadingCount; all 252 objects are
byte-identical across a screen change, so this is definition data, not state.
Two findings fell out: `IsCharging = Yes` switches LoadingCount and
TriggerShotCount to float32 (it partitions the 8 float-encoded records exactly),
and two .tbl entries declare Shell_TCAF_Ship_AAGun with conflicting Power -- the
runtime keeps the one that omits it.
Where the defaulted values *come from* (the IDXD's undecoded binary node region
vs code defaults) is not settled here; they vary per weapon, so they are not one
constructor constant.

Each UI sprite <name>.t32 ships with a <name>.rat companion, and that companion
is the layout record: big-endian u32, a 1280x720 design space at 0x18, and a
placement block of scaleX/scaleY/tint/X/Y. Animated elements repeat the block
with a trailing time field (keyframes); an 'opt ' tag carries a length-prefixed
link to the focused-state record.
Verified in that order, records first: across the four pause buttons exactly one
field varies, stepping 268/338/408/478 at a constant 70px pitch with X fixed at
226; the three items visible in a screenshot of the running game measure
346.0/415.5/485.5, mapping onto those numbers under one constant offset to
within 0.5px. The tutorial build's records are outright framebuffer coordinates,
and compositing its sprites there reproduces the screenshot pixel-accurately.
Also records two mistakes the A/B caught, since a static-only reading would have
shipped both: texture width does not identify a language (Japanese fits English
widths), and the in-mission and tutorial pause menus are separate sprite sets
rather than one set re-packed into slots.

Drove the retail game headless (Canary + lavapipe, vgamepad) to the Ready Room
Arsenal and read the Gallery-Mode DATA SHEET for every weapon the 5%-progress
save reveals.
Two UI->field mappings are CONFIRMED against weapons whose values ARE on disc:
Ammo Capacity == LoadingCount (9/9 exact matches)
Max. Lock Ons == TriggerShotCount (FALCON 9AM 12 == wep_02; BUZZARD 22 == wep_04)
That makes the panel an oracle for fields the disc leaves defaulted, and it is
shown for undeveloped weapons too, so no points need spending. Recovered
TriggerShotCount for wep_05 and wep_60 (both 4, on-disc absent), and bracketed
the defaulted Power / MaximumRange via the Range/Damage letter classes.
Ruled out first: the defaults are not in hidden/DefTables.pak (no WEAPON-schema
objects there) nor in the localized GP_MAIN_GAME_* duplicates.
Also adds the two analysis examples that produce the shopping list of defaulted
fields, the screenshot harness used to drive the menus, and the evidence PNGs.

capture_verify example: clusters every part's ship-relative transform across
the new multi-snapshot, multi-instance F10 captures (5 snapshots, 43 e106
instances, all angles). Verdict: the dominant clusters match the static
assembly to ~1 unit on EVERY part — including BOTH engine nacelles at
(+-131, -133, -131) — so the "engines inside the hull" appearance is the
game's own placement: the engine geometry sits recessed in the aft hull, and
the visible "thrusters" in-game are exhaust FX drawn at the GN_Jet/GN_SJet
frames (Z ~ -570, past the stern).
To close that perception gap the viewer now draws simple exhaust cones at the
game's own jet frames (ship::exhaust_frames; part of the external-parts
toggle). The jet frames flip Z, so the cone apex is authored at +Z and lands
trailing aft — verified in the offline render.

Fixes the two things the user saw in the Ships browser:
- "Can't find the thrusters": show_external defaulted OFF, hiding the engine
rig / bridge / turrets entirely. Externals are EXACT since the node-TRS fix,
so the toggle now defaults ON (relabelled; off = bare hull bodies).
- "Some parts very far away": families without a composite scene graph (fighter
morph sets like f002 whose detached parts are authored far from the origin,
shared turret/prop part families) fell into the stack-at-origin fallback and
rendered as piles with stray pieces. ShipModel now carries has_composite and
the catalog lists only real assembled ships.
Offline audit across ALL stages (ship_audit example): the only far-away
outliers were composite-less f002 morph parts (now filtered); every capital
ship assembles coherently (e108 places its 7 turret instances, f105 its
mirrored shield generators). All primary composites are single-key tracks —
multikey exists only in animation composites (e901 attacks, missile-open),
which assemble_ship does not select.

The runtime capture served its true purpose: as the answer key that exposed the
static encoding. The XBG7 node joint table (node+0x44) holds NINE keyframe
channels [TX TY TZ RY RX RZ SX SY SZ] behind EIGHT pointer slots shifted one
track forward: channel k+1 = f64@(ptr[k]+8), and channel 0 -- TX, which no
pointer names -- sits at ptr[0]-0x48 (tracks are 0x50-byte records, value at
+8). The old 8-slot read took TY as X, RY as Y (usually 0 -- why both hulls
stacked on the centreline) and never saw TX at all (the +-264 hull offsets).
Euler order is Ry(ch3)*Rx(ch4)*Rz(ch5) with angles applied directly, pinned by
the captured engine nacelle Rx(-15)*Rz(30) decomposition. mesh.rs gains
read_trs9/node_rotation; scene_world_nodes and node_transforms both fixed
(saber fin overrides unaffected).
assemble_ship rewritten fully static and exact:
- every composite-node instance placed (alias duplicates collapsed, real
instances kept) including cross-id turret mounts (rou_e303_wep_01_root x2)
- the e_rou_<id>_eng cluster rig mounts at GN_Engine_01 (two mirrored nacelles
+-131 with -+30-degree cant + centre engine) -- world = frame o rig_local
- brg/sld at their exact GN frames (frames were always exact)
- shared-geometry twin pairs at +-TX: X-reflect the instance whose offset
opposes the geometry's dominant side (viewer reverses winding on det<0)
- squeezed node names resolve (wep02 -> wep_02_01)
Ground-truth gate: ship::tests::static_assembly_matches_runtime_capture asserts
static == the baked e106 capture for all 8 parts (T<1.0, R<0.02) plus both
nacelles, both turrets, and the starboard-hull mirror. Viewer now uses pure
static assembly; ship_capture + the baked table remain as the verification
oracle. Renders show a coherent, bilaterally-symmetric destroyer.
81 formats-lib + all disc tests green; viewer builds.
