Sylpheed RE agent b3c8632006 re: a music bank is two stems that play together -- not intro+loop, and
not something to concatenate

Q10, and it starts by withdrawing the question's own premise. BGM_001 is
not three sub-waves of 10 KB / 4.47 MB / 4.67 MB: the 10 KB is the bank
header. A bank is exactly TWO waves, and across all 32 BGM banks on the
disc the two always have the SAME duration -- equal to 0.01 s over
lengths from 37 s to 277 s. That alone kills intro+loop and kills two
halves of one piece, both of which require unequal lengths.

Four banks appear to break the rule and do not: BGM_106-109 are the known
leading-region straddle, and the giveaway is that the entry named
BGM_107.slb contains BANK id=1108. The seek packet counts pin each join
exactly, so they realign to the same two-equal-waves shape rather than
being dropped as noise. That trap goes in METHOD.

Then the roles, by decoding both waves to PCM. They are
sample-synchronous: transient-envelope correlation searched over +/-5 s
peaks at lag +0.00 s, and both waves stop at the same millisecond,
167.663 s. Two stems of one performance, meant to sound at once. Wave 1
is quieter, has almost no bass and is far more L/R-decorrelated, which
reads as a surround-rear pair or a second intensity layer -- I cannot
separate those two from the file, and say so: ChannelMask is 0x0002 on
both, and this game's channel metadata is already documented as
meaningless.

Two things the port needs that are NOT on the disc, both marked as
authored: the track is not a seamless loop (BGM_001 fades out and is
followed by 6.15 s of silence, no loop-point field found), and nothing
names which bank the menu plays -- all 32 BGM cues are numeric.

Raw Blame History

Refuted — claims that were tested and died

Read this before proposing a hypothesis. Every line below was believed at some point, measured, and found false. Reviving one costs a whole iteration and produces nothing.

This file exists because the list had been living in the autonomous agent's loop prompt — the only copy, lost the moment the container was. A refuted result is a real result; it belongs in the corpus like any other.

Format: each entry is the claim as it was believed. Where the true answer is known it follows after . Grouped by subject so a grep for your noun finds the neighbourhood, not just the line.


Offsets, structs and the progress singleton

  • position = instance 0x12c → refuted.
  • +0x29d0 → refuted.
  • "an offset intersection can find a struct's consumer" → only for LARGE or unusual offsets. Small ones have no power (+184: 301/351/115 hits).
  • "a +1956 store means a progress write" → writes go through the COPY, not direct stores. 9 direct stores, none of them a progress write.
  • "the singleton-global filter can find progress writers" → it fails its own control.
  • "the progress copy destination is an r1-relative stack local" → it is a frame register. The r1 assumption returned 0 for all 21 candidates including the known-good — the filter was killed by its own control.
  • "word B's writer also stores the Time/Points record" → it does not.
  • "the debriefing records the metric with the clear bit" → 44 calls, exactly two strings (DEBRIEFING, BASE_INFO), no Time, no Points.
  • "0x820AF030 holds live state" → all 384 words constant; it is a spawned-entity record, not live state.

Screens, classes and RTTI

  • "the transition between menu screens is a cut" → it is a fade through black; a 0.5 Hz screenshot burst simply samples too slowly to see it. screen-transitions.md
  • "the main menu's initial focus is fixed" → three boots of one script gave TUTORIAL, TUTORIAL, NEW GAME.
  • "the title menus drop d-pad presses shorter than ~0.3 s" → refuted by my own data. The menu wraps at both ends; every press registered, and the "missing" step was the wrap. See menu-navigation-semantics.md.
  • "the main menu opens with NEW GAME focused" → it opens on TUTORIAL, 2/2 boots (🟡 a third recorded run implies NEW GAME, so this is reproducible, not invariant).
  • "GP_TITLE builds 6/8/9 are three submenus" → 8 is the JAPANESE main menu, and 6/9 are the English and Japanese EXTRAS submenu. GP_TITLE holds eight screens shipped twice (EN/JP), and exactly one submenu. See ui-title-build-map.md.
  • "the PRESS Ⓐ BUTTON plate is a state of the title build" → it is its own build (2/3), composited over build 4 and faded in a beat later.
  • "the RTTI route can name the anonymous classes" → 1 150 vtables: 1 150 ANON_, 0 rtti_present, 0 base classes.
  • "the sibling vtable methods name the class" → they cannot.
  • "xrefs can name the callers of a vtable method" → no.
  • "the ind_call refutation voids existing corpus claims" → damage bounded, 4/4 caller claims verify. But xrefs.ind_call is a CROSS PRODUCT — always filter kind='call'.
  • "BASE_INFO marks the 5-slot screen family" → it discriminates screen-config from table-read, 9/9 vs 10/10.
  • "a high key count means a rich screen" → sub_82297550 / sub_822A2F00's 27 "keys" are coordinate pairs, i.e. a layout table.
  • "EX_ = the CHALLENGE-mission debriefing" → EX_ is EXTRA, mission-kind 3.
  • "the EX_ selection has not been shown" → it has: [[obj+4]+184] == 3.

Stages, missions and the challenge set

  • "the disc's stages are numbered 1..28" → S01S16 story, S17 cut, S18S23 tutorials, S24S29 challenge.
  • "S24S29 are story missions" → they are the challenge missions.
  • "the challenge missions have their own maps" → they reuse GP_MAIN_GAME_E.pak's stage records.
  • "the challenge REQUIREMENT values are 16,25,26,27,29" → the chain is 16→24→25→26→27→28.
  • "the Extra0n family shares one leaderboard metric" → RECORD_TYPE is per-stage: 3 Time / 3 Points.
  • "stage = filled SHAB count + 1" → refuted.
  • "the first TRIGGER is always the point of no return" → refuted.
  • "EnumUnit_S14.tbl might be missing" / "S14's 13 are a manifest omission" / "asteroids are exempt from the manifest" → S14's 13 are dangling deployments. NEEDS-HUMAN: fly S14.
  • "StageMessageSet_S02.tbl is not in the pak" → it is.
  • "S28_p1 has an asteroid volume with no definition" → refuted.
  • "test_s8p1_asteroid.tbl is test-only" → refuted.
  • "the settings family has 28 or 29 objects" → 24.

ISL / mission scripting

  • "the bytecode is in the .embsec_ sections" → refuted.
  • "only 31 built-ins take a unit" → refuted.
  • "sub_8230C398 is the message pump" → refuted.
  • "bus+8216 is the subscriber registry" → refuted.
  • "the ScriptPhase vtable is ≥200 slots" → 113.

IDXD, paks and naming

  • "IDXD record keys are name_hash" → record keys are tag_hash (case-SENSITIVE); name_hash is case-INSENSITIVE and used for pak keys.
  • "pak TOC order is stage order" / "TOC order is semantic order" → it is not.
  • "the executable holds the asset names" → the image names no data value at all; that route is powerless.
  • "the image might name a data VALUE" → powerless.
  • "the XPR2 manifest names hash to the DefTables tables" → refuted.
  • "the DefTables model names are unreachable" → reachable via the Enumerate declaration tables (1 413/1 425, 99.2 %).
  • "the GP_MAIN_GAME_* unnamed block is undiscovered data" → refuted.
  • "each GP_MAIN_GAME_* Enumerate object declares something" → refuted.
  • "GP_HANGAR_ARSENAL is missing data tables" → refuted.
  • "the Enumeration self-index can name objects" → a self-index names records, not files.
  • "a per-pak prefix might close the 2D blocker" → no.
  • "the + paths might name the 2D or GP_READY_ROOM keys" → the +-dictionary route is exhausted, 0 of 1 817.
  • "the game:\ paths are unresolved" → refuted.
  • "a set-difference over file names can see reuse" → it cannot; join per USER. Per-pak copies are ×6.

Audio

  • "BGM_001.slb is three sub-waves (10 KB + 4.47 MB + 4.67 MB)" → the 10 KB is the bank header; a bank is two waves.
  • "a music bank's two waves might be intro + loop, two variations, or two halves" → they are two stems of one performance, played together — equal duration in 32/32 banks, and sample-synchronous. structures/bgm-two-stems.md
  • "BGM_106BGM_109 break the two-wave rule" → they are the leading-region straddle; realigned across entry boundaries they obey it.
  • "the cue table names which BGM belongs to which screen" → all 32 BGM cues are numeric (BGM_001BGM_109).

Units, weapons, effects and assets

  • "Generic (394) is the unit datasheet" → refuted.
  • "a loadout's Arm1 names an item" → it names a hardpoint slot (Turret_NNN), 59/59.
  • "EnumUnit and the unit datasheet share a vocabulary" → they do not.
  • "the roster is the Generic.Model set" → roster 40, Generic.Model 46, GameResourceID 480 — three vocabularies.
  • "every unit ID is UN_<l>###_<FACTION>_<name>" → the grammar is UN_<letter>###_[<subkind>_]<FACTION>_<name>.
  • "_EXn is the Extra0n index" → three different EX vocabularies exist.
  • "the only two _EX5 names on the disc are the AA gun and the DeltaSaber" → refuted.
  • "running the tutorial will instantiate the _Ttrl weapons" → refuted.
  • "the disc has exactly three EnumWeapon tables" → four.
  • "the wep_NN package gaps are unshipped weapons" / "wep_85 is the tip of a family" → wep_85 is the only declared-but-unshipped asset (59/0/1/26).
  • "nothing is deployed without being declared" → refuted.
  • "effects are one namespace" → refuted.
  • "the 58 undeclared effect names are missing assets" → refuted.
  • "all five orphan effects are unshipped" → refuted.
  • "eff_f0002 ships in Base.xpr" → refuted.
  • "Base.xpr holds more bound effects than ptc_pack" → refuted.
  • "the 34 unlocated are a scatter" → refuted.
  • "the 9 unlocated might be under another prefix" → refuted.
  • "ptc_pack has 532 names" → 727.
  • "the _e/_f law is effect-FIELD-specific" → it is the faction law, 564/564.
  • "a disc-wide .xpr byte search can show an effect is ABSENT" → it cannot.
  • "rot_n001 is on the disc" → refuted.
  • "rou_f004's mesh is in Stage_S28.xpr" → it is in DeltaSaber_A.xpr.
  • "parent + _all + _child is the composite-model convention" → refuted. _hangar is real (59 of 166, 59/59 with a bare twin); _all/_child is not.
  • "Motion_guard_start has no damage variants" → refuted.
  • "CoverArea bits 2 and 3 are mutually exclusive" → refuted.
  • "the 27 unresolved NamePlate values are missing objects" → refuted.

LOD, background and misc tables

  • "EnumLODSet_* is a per-stage family" → EnumLODSet_test.tbl serves 17 stages; 17+5+1 = 23.
  • "there are 8 orphan LOD tables" → 6.
  • "the orphans are stale copies of _test" → refuted.
  • "S25 is absent from the DefTables LOD families" → refuted.
  • "BackGroundID has no referent anywhere" → it is an identity.
  • "BackGroundPackage == BG_<id>.xpr" → refuted.
  • "<X>ID + <X>Package is a convention" → refuted.
  • "Placement_* / RouteTest_* are unattached" → refuted.
  • "the AsteroidDefinition join does not reproduce by hash" → it does.
  • "the 8-value frame is a new finding" → it was already in the corpus.

Loaders, config and tuning

  • "the config reader is XML" → INI.
  • "sub_822F9498 is the unit-definition loader" → it is PlayerParams's.
  • "sub_822AE628 reads the main-game Tweak" → refuted.
  • "sub_8230D1F8 is a rank table" → it is the stage-settings loader.
  • "sub_82286BC8's key list is new" → refuted.
  • "sub_825F2CF0 / sub_825F2F88 read a post-processing table" → refuted.
  • "Booster is a new schema" / "Booster is the player craft's flight envelope" → refuted; nothing selects Booster.
  • "the AnalogRevice/Tweak block is unreachable" → reachable (sub_821A6CF0, base 0x820A1630).
  • "a 0-xref string block has no reader" → refuted.
  • "the AI table was NEEDS-HUMAN" → refuted.
  • "the PG* HUD names are undocumented" → they are documented.
  • "a base-solver row identifies a FUNCTION" → it does not.
  • "a 64K-boundary base is low confidence" → inverted; it is high confidence.
  • "the 0x820B0000 cluster is a false positive" → refuted.
  • "a pointer to a function in the image implies a registry" → refuted. .pdata is not a registry.
  • "the 13 player-facing chatter tables are the WINGMAN tables" → refuted.
  • "the 8 undeclared chatter tables are tutorial chatter" → refuted.
  • "other datasheets ship a schema too" → refuted.
