Input, Save/Load, and Simulation: Post-load Generation, PaintTerrain, and Save/Load Restore

Post-load Generation, PaintTerrain, and Save/Load Restore

The same brush strip is tighter now too: 0x004bc210 stores the selected ordinal and refreshes one scalar caption from table 0x00621e24, 0x004bc260 exposes the cached world coordinate pair plus the currently selected scalar, and 0x004bc290 restyles the ordinal strip 0x0fa1..0x0fa7 plus the mapped mode strip 0x0faa..0x0faf against the current mode dword [0x006d0818+0x8c]. The next unresolved layer is narrower and more semantic: the setup side now has one grounded owner, world_run_post_load_generation_pipeline, and its building-side branch is no longer just one opaque block. We now have a region family, a region-border overlay rebuild, a region-owned structure-demand and placement dispatcher, and a deeper per-region worker that computes category demand, subtracts existing coverage, and tries candidate placements. The category map is tighter too: category 0 falls back to House, category 2 is the year-gated weighted region-profile family that also feeds the localized Industry Weightings stats panel, and category 3 now reaches a separate pool-driven picker whose fallback label is Commercial but whose aligned player-facing stats bucket is City Support. The normalized region band is tighter too: world_region_normalize_cached_structure_balance_scalars 0x00422320 no longer just writes an anonymous cached preview band at [region+0x2e2/+0x2e6/+0x2ea/+0x2ee]. Current growth-report evidence now grounds [region+0x2e2] as the weighted-profit-margin scalar and [region+0x2ee] as the annual-density-adjust scalar later formatted as a percent in Stats - City/Region, with [region+0x2e6/+0x2ea] left as the intermediate normalized-delta and clamped companion slots beneath that final adjust term. The per-region prepass feeding that normalization is tighter too: 0x00420d40 clears [region+0x306/+0x30a/+0x30e], walks the linked placed-structure chain from [region+0x383], accumulates two local placed-structure metrics through 0x0040ca70 and 0x0040ca80, and only for class-0 candidates also folds source field [source+0x141] through 0x0040cec0 into the third accumulator before tailing into the later scalar refresh. That tail helper 0x00420560 is tighter now too: on class-0 regions it revisits the same linked chain and folds a class-mix contribution into [region+0x312], with one source-derived term for candidate class 0, a separate branch keyed by [candidate+0x78c] and [site+0x246] for class 2, one fixed increment for class 3, and no current contribution from class 1. One neighboring collection-side dispatcher is tighter now too: 0x00433b80 only runs when global mutation depth 0x0062be40 is back at zero and then conditionally fans into the optional refresh hooks 0x00481430, 0x00413860, 0x004b2a90, and 0x004931e0. The periodic boundary side is narrower now too. 0x00422100, reached only from simulation_service_periodic_boundary_work 0x0040a590, first requires several live world state gates to stay clear, derives one year-sensitive random threshold from selected-year fields plus world width, then scans the region collection for eligible class-0 regions whose transient dwords [region+0x276] and [region+0x302] are both clear and which fail the city-connection peer probe 0x00420030(1,1,0,0). When the gate passes it picks one random eligible region, derives one small severity bucket from [region+0x25e], stores the scaled amount back into [region+0x276], and appends one queued 0x20-byte record through 0x004337c0 with literal kind 7, the chosen region id, that amount, the fixed payload 0x005c87a8, and sentinel dwords -1/-1. That append helper is now grounded directly too: 0x004337c0 allocates one zeroed linked 0x20-byte node, copies one string or payload seed into [node+0x04..], stores the six trailing caller dwords at [node+0x08..+0x1c], and appends the finished node to the singly linked list rooted at [state+0x66a6]. The gameplay label for that queued-record family is still open, but the structural link from periodic region selection into the scenario-state queue is now direct instead of speculative. One neighboring owner is tighter now too: 0x004358d0 walks the same live region collection and services those pending amounts after linked-site refreshes. When a region's pending amount at [region+0x276] is live and the city-connection peer probes 0x00420030 and 0x00420280 can resolve one matching peer site plus linked company through 0x0047efe0, it formats one localized notice from region name [region+0x356], world scalar [region+0x23a], and the pending amount, publishes that notice through 0x004554e0, posts the amount into company stat slot 4 through 0x0042a080, then clears [region+0x276] and stamps completion latch [region+0x302] = 1. When no peer-company branch is available and byte [region+0x316] is still clear, the same owner publishes one alternate one-shot notice from the same amount and region scalar before setting [region+0x316]. So the pending-region bonus lane is no longer just a queued setup artifact: it has a concrete later service owner and an explicit shell-facing fallback above the same queue family now too. 0x00438710 is the recurring queue service owner above [world+0x66a6] and [world+0x66aa], while 0x00438840 is the tiny dispatch-or-fallback sibling: it forwards the currently active queue node at [world+0x66aa] into the same node-handler table 0x00437c00, or opens the fixed custom modal rooted at localized id 0x153 when no active node is staged. company-credit side effect. One neighboring narrow counter is bounded too: 0x00422850 counts class-0 regions that pass a second 0x00420030 peer-probe variant with fixed flags (1,1,1) plus one caller-supplied trailing dword, and current callers are the query/script dispatch at 0x0042f856 and the later region-stats formatter at 0x004d2088. The remaining setup-side uncertainty has therefore narrowed again: the region seed and border-overlay pair clearly complete before the Setting up Players and Companies... banner is posted; [0x006cec74+0x174] now looks like the direct building-population gate; [0x006cec74+0x178] now looks like the direct seeding-burst gate and selected-year-adjust policy; and [0x006cec74+0x68] now aligns with editor-map mode because the same flag forces the .gmp family in the shell file coordinators while suppressing the later building and seeding branches and diverting the deeper region worker into alternate logic. One write side for that [shell+0x178] policy is now grounded too: inside shell_dispatch_ui_command 0x00464410, command ids 0x9d26..0x9d28 store command_id - 0x9d26 directly into [0x006cec74+0x178], yielding live values 0, 1, and 2. That means the later restore branch is no longer gated by an abstract hidden shell latch; at least one of its adjustment inputs is an explicit UI launch policy and current evidence still does not show that value being recovered from saved state. The 319 lane itself is no longer the open structural gap; it now clearly owns chairman-profile slot seeding, profile-record materialization, a shell editor surface over the same local record family, and a separate live-company presentation path through the company-list window. The later interior order of that same 319 lane is tighter now too: after the route-entry collection refresh on 0x006cfca8 it refreshes the auxiliary route-entry tracker collection 0x006cfcb4, then runs placed_structure_collection_refresh_local_runtime_records_and_position_scalars 0x004133b0, which first drains the queued local-runtime rebuild ids through collection 0x0062b2fc and then sweeps the live placed-structure collection 0x0062b26c for the later position-triplet side refresh, then a flagged world-grid cleanup sweep through the compact grid-flag query 0x00448af0 plus the neighboring local chunk-cell write helper 0x00533fe0, and only after that the later route-entry post-pass at 0x00491c20. The same 319 lane is tighter internally now too: the surrounding placed-structure collection side is no longer just the per-record loader family. 0x004131f0 now cleanly constructs and stream-loads the live placed-structure collection, 0x00413230 constructs the empty runtime pool, 0x00413280 stream-loads tagged placed-structure entries with progress publishing, 0x00413260 is the matching release-and-free owner, and 0x00413550 now clearly resolves one site id, re-enters 0x0040e080 to release local runtime and linked-site follow-on state, and only then unlinks the entry from the live collection. The adjacent helper strip is tighter too: 0x00413620 is the collection-wide linked-peer overlay refresh sweep above 0x0040d2d0; 0x00413660 and 0x004136e0 are the neighboring owner-color and scalar publish sweeps; 0x00413750 is the shared mode-3/6 linked-site preview membership refresh owner; 0x00413860 is the collection-side center-cell roster sweep above 0x0040cd10; 0x004138b0 is the route-link cleanup sweep keyed by one center-cell u16 roster token; 0x004138f0 counts live placed structures whose cached candidate id [site+0x3d0] matches one caller-supplied structure id; 0x00413940 walks the same matching subset and accumulates source field [source+0x141] from 0x0040cec0 with a floor of 1; 0x004139a0 counts entries whose linked peer passes the narrower station-or-transit gate 0x0040d230; 0x00413a00/0x00413aa0 narrow that same linked-peer subset to candidate class 3 and 4; and 0x00413b40 is the subtype-4 companion counter whose last gate is the raw linked-instance candidate byte 0xb9. That 0x00413940 sum is now the direct link-count scale factor consumed by 0x0041e7be above the four cargo-summary banks. One neighboring year-side owner is tighter now too: 0x00435b50 is the shared year-threshold and structure-milestone news pass beneath periodic simulation and startup bring-up. It suppresses itself when the cached previous year still matches or scenario gate [0x006cec78+0x46c38] is live, then publishes fixed year notices for 1865/1895/1920/1958, formatted numeric notices for 1850/1900/1950, and later structure-milestone notices keyed by live counts of specific placed structures resolved through 0x00412af0 and counted through 0x004138f0, appending the finished records into the existing fixed-record/news lanes at 0x006cea4c and 0x004337c0 rather than through a separate hidden journal family. before that later world and shell reactivation tail, world_entry_transition_and_runtime_bringup runs one distinct post-bundle status and runtime refresh phase that posts progress ids 0x196 and 0x197 through 0x005193f0/0x00540120 with paired 0x004834e0 follow-ons, refreshes the live event collection at 0x0062be18 through scenario_event_collection_refresh_runtime_records_from_packed_state 0x00433130, rebuilds the scenario-side port-or-warehouse cargo recipe runtime tables through 0x00435630, and then runs the named-candidate availability preseed through 0x00437743. The recipe rebuild lane itself is tighter now too: 0x00435630 resolves both supplied and demanded token strings through the exact live cargo-name matcher cargo_collection_find_entry_by_exact_name 0x0041e9f0, fills empty token strings from the first live cargo entry before that match, and in mode 3 loops until the supplied and demanded strings no longer compare equal. The importer-side bridge is tighter now too: each of the twelve recipe books writes its active-line count into the paired runtime count lane beside the imported 0xbc descriptor strip, and after the full twelve-book sweep the helper explicitly re-enters structure_candidate_collection_rebuild_runtime_records_from_scenario_state 0x00412d70 when the live candidate collection exists. That keeps the strongest current static split narrow and concrete: mode-zero demand rows can still preserve readable cargo-name text in the saved recipe books, but only the nonzero imported rows reach the live 0xbc descriptor array, and the unresolved supply-marker forms still have no special decode path before the exact matcher runs. The immediate helper strip under that bridge is tighter now too: 0x00411d50 is the narrow descriptor-pattern predicate that returns true only when every imported descriptor keeps mode 0 and at least one descriptor has no subordinate rows, while 0x00411da0, 0x00411e10, and 0x00411e50 are conservative fixed-table accessors over candidate slot [candidate+0x798], exposing one copied name plus either a scalar pair or scalar triplet from the same fixed row in 0x005ed338..0x005edca4 rather than a separate loader family. One later subphase is tighter now too: before the broad world-reactivation sweep it posts progress ids 0x32dc/0x3714/0x3715, reloads one 0x108-byte packed profile block through 0x00531150, conditionally copies staged runtime-profile bytes back into 0x006cec7c while latch [profile+0x97] is set, mirrors the grounded campaign-scenario bit [profile+0xc5] and sandbox bit [profile+0x82] into world bytes [world+0x66de] and [world+0x66f2], and restores the selected year/profile lane through a tighter two-stage calendar path than before. Current local disassembly now shows the raw saved lane at [profile+0x77] first feeding helper 0x0051d3f0 with constant components (month=1, day=1, subphase=0, tick=0), which writes the resulting Jan-1-style tuple dwords into [world+0x05/+0x09]. Only after that seed does the same lane enter one mode-sensitive adjustment branch: non-editor startup mode can decrement the lane by 1 or 3 depending on shell-state editor gate [0x006cec74+0x68], shell-side selected-year-adjust policy [0x006cec74+0x178], and the saved special-condition slot [0x006cec78+0x4af7], and only that save/load bridge is narrower on the candidate side too: the constructor-side load owner structure_candidate_collection_construct_and_stream_load_runtime_records 0x004131f0 seeds global pool 0x0062b268 and immediately re-enters the broader collection importer structure_candidate_collection_stream_load_rebuild_runtime_summaries_and_refresh_named_availability 0x00412fb0. That owner streams each packed candidate body back through structure_candidate_stream_load_runtime_record_and_rebuild_cargo_state 0x004120b0, reruns the scenario-side recipe projection at 0x00412d70, refreshes the stem-policy lane at 0x00412ab0, rebuilds the collection aggregate subtotal band at [pool+0x8c..+0x9c], repopulates the fixed name catalog at 0x0061dbc2/0x0061dc09 for non-subtype-1 zero-availability candidates whose live ids stay within 0x6e, and then reruns the named-availability pass at 0x00412c10 before returning. The neighboring placed-structure side is bounded too: global pool 0x0062b26c comes from placed_structure_collection_construct_empty_runtime_pool 0x00413230, while the paired tagged collection owners 0x00413280 and 0x00413440 now own the broader placed-structure stream load/save path around tags 0x36b1/0x36b2/0x36b3 and the per-entry virtual load/save slots +0x40/+0x44. adjusted lane then feeds helper 0x0051d390 before world_set_selected_year_and_refresh_calendar_presentation_state 0x00409e80 stores the final absolute counter into [world+0x15] and refreshes [world+0x0d/+0x11]. That means the restore no longer reads as a direct [profile+0x77] -> [world+0x15] copy; the raw lane seeds the tuple immediately, but the final absolute-counter restore still depends on live shell/startup context. That dependency is tighter now too: current local evidence shows [shell+0x178] == 1 decrementing the restored lane by 1, [shell+0x178] == 2 subtracting 3, and otherwise a nonzero [0x006cec78+0x4af7] supplying the fallback -1 branch. That field is no longer unresolved: current local disassembly now shows 0x00436d10 bulk-zeroing the dword table rooted at [startup+0x4a7f] through rep stos, which includes +0x4af7, while the editor-side special conditions owner at 0x004cb2b0/0x004cb8e0 counts and commits that same 49-entry table from the static rule descriptors at 0x005f3ab0. The .smp save or restore family now grounds that live band directly too: world_runtime_serialize_smp_bundle 0x00446240 writes 49 dwords from [world+0x4a7f..+0x4b3f] plus one trailing scalar at [world+0x4b43], and world_load_saved_runtime_state_bundle 0x00446d40 restores the same fixed 0xc8-byte band symmetrically. Slot 30 in that table is localized pair 3722/3723 Disable Cargo Economy, so +0x4af7 now reads as the live copy of that saved scenario rule, not a startup-runtime-only mystery latch. The neighboring fixed reads line up with the same rule cluster too: +0x4aef is slot 28 Completely Disable Money-Related Things, +0x4af3 is slot 29 Use Bio-Accelerator Cars, +0x4afb is slot 31 Use Wartime Cargos, +0x4aff is slot 32 Disable Train Crashes, +0x4b03 is slot 33 Disable Train Crashes AND Breakdowns, and +0x4b07 is slot 34 AI Ignore Territories At Startup. So the remaining loader gap is narrower than before: the restore still depends on live shell policy [shell+0x178], but the +0x4af7 input itself is save-derived scenario rule data rather than something that requires runtime tracing to discover. Its read-side family is no longer isolated to the selected-year restore either: it also shapes the chunk size in simulation_run_chunked_fast_forward_burst 0x00437b20 and appears in candidate/local-service selection and station-detail-side scoring branches around 0x0047f910, 0x00410d87, and 0x005069c6, which now makes this whole slot cluster look like broader runtime consumers of scenario special conditions rather than one startup-only mode enum. One file-side anchor is now tighter too: the checked classic and 1.05 gmp/gms/gmx corpus does expose the same aligned 0x0d64..0x0e2c 50-dword band as the grounded .smp runtime save or restore copy into [world+0x4a7f..+0x4b43], but most checked file families only populate a sparse subset of that band. The first 36 dwords still behave like the older inferred fixed rule matrix with hidden slot 35 fixed to sentinel value 1, while the trailing 13 unlabeled rule lanes plus one scalar vary much more selectively by file family. Current local corpus scans make that split concrete: the grounded 1.05 scenario-save family (p.gms, q.gms) stably lights lanes 35, 37, 39, 44, 45, 46, 47, 48; the base 1.05 save family (Autosave.gms, nom.gms) only shares lane 35 stably and otherwise varies sparsely through 42, 45, and 47; the checked grounded 1.05 maps, the lone 1.05 alt save, and the visible sandbox-family .gmx files keep only the sentinel lane 35 nonzero. So the current loader boundary is narrower than before: the .smp path still gives a grounded direct runtime-band restore, and checked gmp/gms/gmx files now show a partially populated projection of that same aligned band rather than a wholly separate fixed record family. The overlap against the later scalar window is now explicit too: trailing band indices 36..49 are byte-identical with post-window offsets 0x00..0x34, so every nonzero lane in that prefix of the post-sentinel scalar window is also a nonzero lane in the aligned runtime-rule band. That means the real “other fields” boundary inside the post-sentinel window starts only at 0x0e2c: 0x0df4..0x0e2c is the aligned-band overlap prefix, while 0x0e2c..0x0f30 is the later tail that still looks like save-side scalar state. Local corpus scans now make that tail split more specific. The base 1.05 save family (Autosave.gms, nom.gms) shares a stable tail subset at relative offsets 0xb4, 0xc0, 0xe0, 0xfc, and 0x100, with additional per-file lanes around them. The 1.05 scenario-save family (p.gms, q.gms) has a much denser stable tail covering 0x08, 0x0c, 0x10, 0x14, 0x20, 0x24, 0x28, 0x30, 0x34, 0x3c, 0x5c, 0x6c, 0xa0, 0xa8, 0xbc, 0xc0, 0xc4, 0xc8, 0xcc, 0xdc, 0xe0, 0xe4, 0xe8, 0xf4, 0xf8, and 0xfc; those values still differ per save, but the occupancy is stable. The lone 1.05 alt save (g.gms) only lights 0x20, 0x34, 0xf0, and 0xf4. Grounded map families and classic saves keep the tail zeroed, while the only current map-side outlier remains Tutorial_2.gmp under the broad unknown map-family bucket. The immediately following fixed file window at 0x0df4..0x0f30 is now bounded separately as well: checked maps and classic saves leave that whole post-sentinel band zeroed, while checked 1.05 saves carry sparse nonzero dwords there, many of which decode cleanly as normal little-endian f32 values. That makes the adjacent band look like a 1.05 save-only runtime band rather than scenario-static payload, even though its semantics are still open. One numeric alignment inside that band is now exact too: the tail start 0x0e2c is the same relative distance from the aligned runtime-rule base 0x0d64 as live object offset +0x4b47 is from grounded world-rule base [world+0x4a7f], so the bounded tail window 0x0e2c..0x0f30 is offset-aligned with live bytes [world+0x4b47..+0x4c4b]. The first grounded live field at that boundary is no longer anonymous. 0x004367c0 sets one outcome mode in [world+0x4a73], zeros [world+0x4d], snapshots the selected-year lane to [world+0x4c88], and then copies localized id 2923 You lose. or 2924 You win, cheater... into [world+0x4b47]; 0x00472dd0 formats localized id 3918 %1 has won the game! with one live profile name and writes that string into the same destination; and one compact runtime-effect branch inside world_apply_compact_runtime_effect_record_to_resolved_targets 0x00431b20 resets the same destination to the fixed placeholder token at 0x005c87a8. That gives a grounded live owner above the latch too: simulation_service_world_outcome_mode_prompt_and_transition_effects 0x00436350 is the frame-serviced consumer of [world+0x4a73], stamping completion latch [world+0x4a77], driving the outcome-mode prompt rooted at localized id 0x169, and triggering the world-side transition paths around 0x482150 while leaving [world+0x4b47] as the current outcome-status payload source. That gives a grounded live interpretation for the start of the tail: [world+0x4b47] is the start of a victory or outcome status-text buffer, not a float lane. The same evidence also gives a useful caution: those live helpers copy up to 0x12c bytes into [world+0x4b47..+0x4c73], so the current bounded file-tail window 0x0e2c..0x0f30 cuts through the first 0x104 bytes of a grounded text field rather than ending on a clean live-field boundary. One small continuation probe now tightens that edge: the remaining file window 0x0f30..0x0f58 is exactly the last 0x28 bytes needed to reach the clean live-field boundary at [world+0x4c73], and checked 1.05 saves still carry sparse nonzero bytes in that continuation window rather than a trailing text-looking suffix. Checked 1.05 save bytes in the aligned region therefore still do not resemble preserved text; they stay mostly zero at the beginning and many nonzero lanes decode as ordinary f32 values. So the safest current note is: the tail is offset-aligned with the live object beyond +0x4b43, but it is not yet a validated byte-for-byte mirror of the live [world+0x4b47] status-text buffer, and the current nonzero save-side content continues right up to the first clean field edge at 0x0f58. The next exact grounded fields after that edge are byte lanes, not restored dwords: 0x0f59 maps to [world+0x4c74] Auto-Show Grade During Track Lay, 0x0f5d maps to [world+0x4c78] Starting Building Density Level, 0x0f61 maps to [world+0x4c7c] Building Density Growth, 0x0f65 maps to grounded dword [world+0x4c80] leftover simulation time accumulator, and 0x0f6d maps to byte [world+0x4c88] selected-year lane snapshot. The first later grounded dword after that is [world+0x4c8c] at 0x0f71. The frame-side follow-on above the outcome prompt is grounded now too: after 0x00436350 stamps [world+0x4a77], internal branch 0x0043963d keeps running only while [world+0x4a7b] still matches the current step-local marker, then services the queued runtime-effect record family rooted at [world+0x66a6] through 0x00438710, conditionally opens Overview.win through 0x004f3a10 when the preview fixed-record collection at 0x006cea4c still has one admissible entry, and conditionally opens LoadScreen.win page 0 through 0x004e4ee0 when shell latch 0x006d4000 is clear and world flag [world+0x4d] is still nonzero. The same branch also conditionally toggles pause or resume through 0x00437a60 when no live multiplayer session object is present at 0x006cd8d8. That splits the outcome prompt owner 0x00436350 cleanly from the later post-transition follow-on strip instead of leaving both behaviors folded into one unnamed frame tail. That means the simple 4-byte file-lane model stops matching grounded live field boundaries immediately after the text-buffer edge: the post- 0x0f58 file bytes are still offset-correlated to live state, but they are no longer naturally dword-aligned with the next grounded object fields. The new byte-neighborhood probe makes the mismatch more concrete. In checked 1.05 scenario saves, the exact grounded byte offsets themselves do not look like clean selector values: p.gms carries 0x33 at 0x0f5d and 0x8c at 0x0f6d, while q.gms carries 0xcc and 0xba at those same offsets. The only clean float-looking starts in that neighborhood instead appear one byte earlier, at 0x0f5c and 0x0f6c: p.gms decodes those as roughly 7.6 and 6.0172, while q.gms decodes them as roughly 23.6 and 44.6824. That tightens the current read further: the checked save bytes remain offset-correlated to the live [world+0x4c74..+0x4c8c] neighborhood, but they are still not a validated byte-for-byte mirror of the exact live field layout. Local A second byte-oriented neighborhood immediately after that now has the same kind of split rather than a clean restored-field mirror. The earlier grounded anchors in that band all stay zero in the checked 1.05 saves: exact file offset 0x0f87 maps to selected-year bucket companion scalar [world+0x4ca2], while 0x0f93 and 0x0f97 map to the two startup-dispatch reset-owned bands [world+0x4cae] and [world+0x4cb2], and the local corpus leaves all three exact dword starts zeroed. The same is true for the later exact byte-owned policy lanes: file offsets 0x0f78, 0x0f7c, 0x0f7d, and 0x0f7e map cleanly to grounded byte fields [world+0x4c93] and [world+0x4c97..+0x4c99]: the linked-site removal follow-on gate plus the three editor locomotives-page policy bytes All Steam Locos Avail., All Diesel Locos Avail., and All Electric Locos Avail.. In the checked 1.05 save corpus those four exact byte lanes all stay 0, which is at least structurally clean. The later grounded dword fields in the same neighborhood are less direct again. Exact file offset 0x0f9f maps to [world+0x4cba] (the station-list selected-station mirror) and exact offset 0x0fa3 maps to cached available-locomotive rating [world+0x4cbe], but the checked save bytes at those exact dword starts do not look like clean preserved ids or floats. The only stable float-looking starts sit three bytes earlier, at 0x0f9c and 0x0fa0: p.gms yields roughly 96.8754 and 186.4795, q.gms yields 329.9467 and the same 0x0fa0-side candidate shape, g.gms yields 7.0 and 95.8507, and Autosave.gms only shows the later 0x0fa0 candidate at about 68.2629. So this later band now has the same conservative read as the post-text one: the save bytes are still offset-correlated to grounded live fields, but the exact live byte or dword layout is not yet validated as a direct on-disk mirror. One more structural cut is now grounded beyond that neighborhood. The aligned scalar plateau 0x0fa7..0x0fe7 ends exactly at the later recipe-book root [world+0x0fe7] already grounded in the port-or-warehouse cargo editor and runtime rebuild path. We still do not have live semantic names for the plateau itself, but its aligned dword run now splits cleanly by save family. The base 1.05 saves (Autosave.gms, nom.gms) carry one stable signature with 0x0faf = 0x8000003f, 0x0fb3 = 0x75c28f3f, repeated 0x75c28f3c lanes through 0x0fbf, a sign-flipped lane 0x0fc3 = 0xa3d70a3c, one tiny marker at 0x0fc7 = 0x0000003b, and 0x0fcb = 0x00300000. The scenario-save family (p.gms, q.gms) carries a different stable plateau over the same offsets, beginning 0x0faf = 0x4000003f, 0x0fb3 = 0xe560423f, then 0x03126f3b, 0x1374bc3c, and paired 0x23d70a3c lanes at 0x0fbf/0x0fc3, with 0x0fc7 = 0x0000003c. The alt-save family (g.gms) follows the base signature through 0x0fc7, then diverges sharply into the same 0xcdcdcd.. fill pattern already seen in its earlier header lanes. So the current best fit for 0x0fa7..0x0fe7 is a family-shaped aligned scalar plateau that belongs to save-side runtime state and terminates immediately before the grounded recipe-book block, not one more directly named live-field mirror. One conservative loader-side summary probe now starts exactly at that recipe root instead of extending the plateau model further. The fixed recipe-book block spans twelve books from 0x0fe7 with stride 0x4e1, and the checked map/save pairs Alternate USA.gmp -> Autosave.gms, Southern Pacific.gmp -> p.gms, and Spanish Mainline.gmp -> g.gms preserve that rooted block byte-for-byte in the sampled local corpus. The current probe therefore treats it as preserved scenario payload rather than save-only runtime drift and only reports per-book signatures: a coarse head kind over the pre-line region, the raw book+0x3ed annual-production dword, and one raw summary for each of the five fixed 0x30-byte cargo lines beginning at book+0x3f1: coarse line kind, raw mode dword, raw annual-amount dword, and the raw supplied/demanded cargo-token dwords at +0x08 and +0x1c. That is enough to separate zero, 0xcd-filled, and mixed books or lines without overstating line semantics beyond the grounded editor/runtime ownership already documented below. Local corpus clustering now makes the remaining split more specific. The base 1.05 save family (Autosave.gms, nom.gms) shares a narrow tail-heavy subset with stable relative offsets 0xec, 0xf8, 0x118, 0x134, and 0x138, while still varying in value across files. The 1.05 scenario-save family (p.gms, q.gms) shares a much broader stable set spanning almost the whole window from 0x04 through 0x134, again with per-file scalar differences but consistent occupancy. Pairwise compare runs tighten that read further: Autosave.gms vs nom.gms does not preserve one common numeric tail signature even at the shared base-save offsets, and p.gms vs q.gms keeps the broad scenario-save occupancy pattern but still changes every shared value, with q.gms additionally lighting two extra lanes at 0x78 and 0x84. So the current best fit is “family-shaped live scalar state” rather than family-default constants. The lone 1.05 alt-save sample (g.gms) only lights up four lanes at 0x58, 0x6c, 0x128, and 0x12c. The checked 1.05 maps and classic saves stay zero in that same bounded window, which strengthens the current read that this is runtime-save scalar state rather than generic map payload. One older unknown map-family outlier in the local corpus does still carry a populated window: Tutorial_2.gmp under the classic install tree. So the safest current note is “zero for grounded map families and classic save families, nonzero for observed 1.05 save families, with one older unknown-map exception.” Static consumer grounding is still sparse for that tail: direct object-offset hits currently only name the trailing scalar [world+0x4b43] through the editor panel and .smp save or restore family, while local opcode searches do not yet surface equally direct reads for the intervening +0x4b0b..+0x4b3f tail lanes. So the save-file family clustering is now strong, but those later tail scalars remain structurally bounded rather than semantically named. The same branch is no longer world-entry-only either: current local disassembly now shows the identical lane-adjust and 0x51d3f0 -> 0x51d390 -> 0x409e80 sequence in the post-fast-forward selected-year tail at 0x004370e0, which lines up with the existing post-fast-forward callers already mapped under 0x00433bd0, 0x00435603, 0x0041e970, and 0x00436af0. That restore now also has some neighboring slot semantics bounded well enough to carry in the loader notes. Slot 31 [0x006cec78+0x4afb] is no longer best read as an unnamed runtime cargo-economy latch: local disassembly now ties it directly to the saved special-condition table entry Use Wartime Cargos, and the strongest current runtime owner is structure_candidate_collection_refresh_cargo_economy_filter_flags 0x0041eac0. Inside that candidate-collection sweep the branch at 0x0041ed37 only activates when slot 31 is set and then treats the string family Clothing, Cheese, Meat, Ammunition, Weapons, and Diesel as one special cargo set before writing the live candidate filter byte [entry+0x56]. That makes the old read-side note around 0x00412560 tighter too: the neighboring descriptor gate is now best understood as using the live copy of the Use Wartime Cargos scenario rule, not an anonymous cargo-economy mode byte. Slot 34 [0x006cec78+0x4b07] is similarly bounded on the runtime side: the wrapper at 0x004013f0, which sits immediately above the broader company-start or city-connection chooser 0x00404ce0, snapshots region dword [entry+0x2d] across all 0x18 live region records in 0x006cfc9c, zeros that field while the chooser runs, and then restores the original values on exit. That is a strong current fit for the editor rule AI Ignore Territories At Startup, even though the exact meaning of region field +0x2d remains open. Slot 29 [0x006cec78+0x4af3] is less semantically tidy but still worth carrying as a bounded consumer family: the branch at 0x0041d286 activates one later placed-structure or building-side scoring path only when that slot is nonzero and the linked candidate or era record at [entry+0x41] equals 5, while two already-grounded world helpers world_scan_secondary_grid_marked_cell_bounds 0x0044ce60 and world_service_secondary_grid_marked_cell_overlay_cache 0x0044c670 also gate on the same slot. So the identity of slot 29 as saved rule data is grounded, but the downstream runtime semantics are still mixed enough that the loader should preserve the raw value without trying to rename its whole consumer family yet. The neighboring train-safety slots are now bounded enough to keep as a cautious runtime split too. Slot 33 [0x006cec78+0x4b03] Disable Train Crashes AND Breakdowns is the coarse gate in the currently recovered train-side deterioration family around 0x004af8a0: the very first branch at 0x004af8ab jumps straight to the function tail when the slot is set, bypassing the year-scaled threshold build, the later random or threshold comparison, and the two follow-on state transitions at 0x004ad7a0 and 0x004ada00. Slot 32 [0x006cec78+0x4aff] Disable Train Crashes is narrower in the same family: after the threshold path has already run, the branch at 0x004af9c1 uses slot 32 to suppress only the lower failure-transition path and force the milder follow-on at 0x004ada00. That same slot-33 read also appears in the smaller train-side scalar query at 0x004ac460, where setting it returns one fixed float immediately before the ordinary route-object-dependent calculation runs. So the current best loader-facing read is: slot 33 is the broad train deterioration bypass, slot 32 is the narrower crash-only branch inside that same family, but the exact player-facing names of the two unnamed train helpers still need one more naming pass. That restore now also has one concrete file-side correlation in the classic .gms family: local save inspection now consistently finds 0x32dc at 0x76e8, 0x3714 at 0x76ec, and 0x3715 at 0x77f8 in Autosave.gms, kk.gms, and hh.gms, leaving one exact 0x108-byte span from 0x76f0 to 0x77f8 between 0x3714 and 0x3715. That span already carries staged-profile-looking payload text such as British Isles.gmp, so the current static-file evidence now supports the atlas-side 0x108 packed-profile note for the classic save family even though the exact field layout inside that block is still unresolved. The same classic corpus is tighter now too: inside that 0x108 span the map-path C string begins at relative offset 0x13, the display-name C string begins at 0x46, the block is otherwise almost entirely zeroed, and the three local samples are byte-identical except for the leading dword at +0x00 (3 in Autosave.gms and hh.gms, 5 in kk.gms). The currently atlas-tracked bytes [profile+0x77], [profile+0x82], [profile+0x97], and [profile+0xc5] are all 0 in that classic sample set, so the current file-side evidence grounds the block boundaries and the embedded strings but does not yet show live examples of those branch-driving latches being set. One 1.05-era file-side analogue is now visible too, but only as an inference from repeated save structure rather than a disassembly-side field map: local .gms files in rt3_105/Saved Games carry one compact string-bearing block at 0x73c0 with the same broad shape as the classic profile slab, including a leading dword at +0x00, one map-path string at +0x10, one display-name string at +0x43, and a small nonzero tail around +0x76..+0x88. In that 1.05 corpus the analogue bytes at relative +0x77 and +0x82 are now nonzero in every checked sample (Autosave.gms/nom.gms show 0x07 and 0x4d; p.gms/q.gms show 0x07 and 0x90; g.gms shows 0x07 and 0xa3), while relative +0x97 and +0xc5 remain 0. The compared 1.05 save set is tighter now too: Autosave.gms and nom.gms cluster together on Alternate USA.gmp with +0x82 = 0x4d, g.gms carries Spanish Mainline.gmp with +0x82 = 0xa3, and p.gms/q.gms cluster on Southern Pacific.gmp with +0x82 = 0x90; across all five files the same inferred analogue lane at +0x77 stays fixed at 0x07, while the same map- or scenario-sensitive tail word at +0x80 tracks those 0x4d/0xa3/0x90 byte lanes (0x364d0000, 0x29a30000, 0x1b900000). The leading dword at +0x00 also splits the same corpus, with Autosave.gms alone at 3 and the other four checked 1.05 saves at 5. That is enough to say the wider save corpus does contain nonzero candidates for two of the atlas-tracked profile lanes, and that one of them varies coherently with the loaded scenario family, but not yet enough to claim that the 1.05 block reuses the exact same semantic field assignments as the classic one. The loader-side family split is tighter now too: p.gms and q.gms no longer live under a generic fallback; their save headers now classify as one explicit rt3-105-scenario-save branch with preamble words 0x00040001/0x00018000/0x00000746 and the early secondary window 0x00130000/0x86a00100/0x21000001/0xa0000100, while g.gms now classifies as a second explicit rt3-105-alt-save branch with the different preamble lane 0x0001c001/.../0x00000754 and early window 0x00010000/0x49f00100/0x00000002/0xa0000000. That branch now carries the same bootstrap, anchor-cycle, named 1.05 trailer, and narrow profile-block extraction path as the other 1.05 saves. The bridge just below that trailer is now explicit too: the common 1.05 save branch carries selector/descriptor 0x7110 -> 0x7801 in Autosave.gms and 0x7110 -> 0x7401 in nom.gms, and both still reach the same first later candidate at span_target + 0x189c, well before the packed profile at span_target + 0x3d48; the rt3-105-alt-save branch instead carries 0x54cd -> 0x5901 and its first later candidate lands at packed_profile + 0x104, essentially on the profile tail; the scenario-save branch still diverges locally with 0x0001 -> 0x0186 and never enters that later 0x32c8-spanned bridge at all. The common-branch bridge payload is narrower now too: both checked base saves expose the same 0x20-byte primary block at 0x4f14 followed by the same denser secondary block at 0x671c, 0x1808 bytes later, and that secondary block now appears to run intact up to the packed-profile start at 0x73c0 for a total observed span of 0xca4 bytes. The trailing slice of that secondary block is now typed one level further: a small header at secondary+0x354 carries the observed stride 0x22, capacity 0x44, and count 0x43, followed by a fixed-width 67-entry name table starting at secondary+0x3b5 and running through names like AluminumMill, AutoPlant, Bakery, Port00..11, and Warehouse00..11, with a short footer (dc3200001437000000) after the last entry. The trailing per-entry word is now surfaced too: most entries carry 0x00000001, while the currently observed zero-trailer subset is Nuclear Power Plant, Recycling Plant, and Uranium Mine. That footer is tighter now too: it parses directly as 0x32dc, 0x3714, and one trailing zero byte, so the shared map/save catalog currently ends on the same two grounded late-rehydrate progress ids that the classic staged-profile band already exposed. The strongest structural read is therefore that the entire 0x6a70..0x73c0 catalog region is shared verbatim between Alternate USA.gmp and the derived Autosave.gms, not rebuilt independently during save. Combined with the earlier grounded record-layout work under 0x00437743, 0x00434ea0, and 0x00434f20, the current safest semantic read is that this shared catalog is the bundled source form of the scenario-side named candidate-availability table later mirrored into [state+0x66b2], with each entry's trailing dword now reading as the same availability override bit later copied into [candidate+0x7ac]. The candidate-side refresh strip is tighter now too: 0x00412c10 walks the live candidate pool, forces [candidate+0x7ac] = 1 whenever availability bytes [candidate+0xba/+0xbb] are already set or subtype [candidate+0x32] is not 2, and only for the remaining subtype-2 records does it consult 0x00434ea0 by stem before tailing into the dependent cargo-economy filter rebuild 0x0041eac0. The adjacent collection helpers also read cleanly now: 0x00412bd0 is the collection-wide 0x00411ee0 cargo-summary rebuild sweep over imported 0xbc descriptor arrays, while 0x00412ba0 is the remove-and-release sibling that clears one candidate's dependent runtime descriptor and cargo-membership tables through 0x00411cb0 before erasing that id from the pool. One lower runtime detail is explicit now too: 0x00411ee0 does not just “refresh summary tables.” It rebuilds the two emitted cargo-id tables at [candidate+0x79c] and [candidate+0x7a0] from one temporary 0x35-cargo mark band, stores their counts at [candidate+0x7a4] and [candidate+0x7a8], and accumulates the scaled runtime rates into [candidate+0xa1..+0xb8]; mode-0 descriptor rows use the shared production cap at [candidate+0x2a] divided by the descriptor amount, while nonzero mode rows bypass that cap scaling. The loader-side coverage is tighter now too: the same table parser now attaches both to the common-save bridge payload and directly to the fixed source range in .gmp files and the non-common rt3-105-scenario-save / rt3-105-alt-save branches. That makes the scenario variation explicit instead of anecdotal. Alternate USA keeps only three zero-availability names in this table (Nuclear Power Plant, Recycling Plant, Uranium Mine), Southern Pacific widens the zero set to twelve (AutoPlant, Chemical Plant, Electric Plant, Farm Rubber, FarmRice, FarmSugar, Nuclear Power Plant, Plastics Factory, Recycling Plant, Tire Factory, Toy Factory, Uranium Mine), and Spanish Mainline widens it again to forty-two, including Bauxite Mine, Logging Camp, Oil Well, Port00, and the Warehouse00..11 run while also flipping Recycling Plant back to available. The header lanes just ahead of the table vary coherently with those scenario branches too: Alternate USA carries header_word_0 = 0x10000000, Southern Pacific carries 0x00000000, and Spanish Mainline carries 0xcdcdcdcd, while the structural fields from header_word_2 onward remain stable (0x332e, 0x1, 0x22, 0x44, 0x43) and the 9-byte footer still decodes as 0x32dc, 0x3714, 0x00 in all three checked maps. A wider corpus scan over the visible .gmp/.gms files makes those two anonymous header lanes less mysterious too: the parser currently sees only three stable (header_word_0, header_word_1) pairs across 79 files with this table shape, namely (0x00000000, 0x00000000), (0x10000000, 0x00009000), and (0xcdcdcdcd, 0xcdcdcdcd). The zero-availability count varies widely underneath the first and third pairs (0..56 under the zero pair, 14..67 under the 0xcdcdcdcd pair), so those two lanes no longer look like counts or direct availability payload; the safest current read is that they are coarse scenario-family or source-template markers above the stable 0x332e/0x22/0x44/0x43 table header, with 0xcdcdcdcd still plausibly acting as one reused filler or sentinel lane rather than a meaningful numeric threshold. Current exported disassembly notes still do not ground one direct loader-side or editor-side consumer of header_word_0 or header_word_1 themselves, so that family-marker read remains an inference from corpus structure rather than a named field assignment. The new loader-side compare command makes the save-copy claim sharper too: for the checked pairs Alternate USA.gmp -> Autosave.gms, Southern Pacific.gmp -> p.gms, and Spanish Mainline.gmp -> g.gms, the parsed candidate-availability table contents now match exactly entry-for-entry, with the only reported differences being the outer container family (map vs save) and source-kind path (map-fixed-catalog-range vs the save-side branch). has the explicit companion world_refresh_selected_year_bucket_scalar_band 0x00433bd0, which rebuilds the dependent selected-year bucket floats after the packed year changes; and then rehydrates the named locomotive availability collection at [world+0x66b6] through locomotive_collection_refresh_runtime_availability_overrides_and_usage_state 0x00461e00. That locomotive-side restore is tighter now too: its tail explicitly re-enters scenario_state_refresh_cached_available_locomotive_rating 0x00436af0, which rebuilds one cached available-locomotive rating at [state+0x4cbe] from the current year plus the strongest surviving available locomotive-side rating scalar [loco+0x20], and the tiny query sibling 0x00434080 is now bounded as the shell-side clamped read helper over that same cached field, with the grounded shell-side reader later bucketing that value against 40/50/70/85/100. The same rehydrate band also refreshes the live structure-candidate filter and year-visible counts through structure_candidate_collection_refresh_filter_and_year_visible_counts 0x0041e970, rebuilding the paired per-slot bands at [candidates+0x246] and [candidates+0x16e] and the aggregate counts at [candidates+0x31a] and [candidates+0x242]; the same late checkpoint also re-enters placed_structure_collection_seed_candidate_subtype2_runtime_latch 0x00434d40, which seeds runtime dword [candidate+0x7b0] across subtype-2 candidate records before the later world-wide reactivation sweep. That checkpoint also now has an explicit shell-facing scalar publisher: world_publish_shell_controller_progress_scalar_from_year_thresholds_or_selector_overrides 0x004354a0 writes one clamped 0..255 value into the current shell presentation object, sourcing it either from the shell selector override pairs or from the scenario-side year-threshold band rooted at [state+0x3a/+0x51/+0x55/+0x59/+0x5d/+0x61]; and just ahead of the later scenario-side recipe rebuild, the same band also re-enters scenario_state_ensure_derived_year_threshold_band 0x00435603, which only falls into its heavier rebuild body while [state+0x3a] < 2 and otherwise leaves the derived year-threshold companion slots [state+0x51/+0x55/+0x59/+0x5d/+0x61] unchanged. The neighboring late status checkpoints around progress ids 0x196 and 0x197 also share one explicit stage gate now: world_query_global_stage_counter_reached_late_reactivation_threshold 0x00444dc5 compares the global counter 0x00620e94 against threshold 0x9901, and the two current callers use a negative result to clear [world+0x39] before the broader world and shell reactivation sweep. The later reactivation tail is tighter now too: it includes the region-center world-grid flag reseed pass 0x0044c4b0, which clears bit 0x10 across the live grid and then marks one representative center cell for each class-0 region through 0x00455f60; its immediate sibling 0x0044c450 then reruns placed_structure_rebuild_candidate_cargo_service_bitsets 0x0042c690 across every live grid cell. The small secondary-raster premark helper 0x0044c570 is bounded now too: it only admits cells whose current raster byte has no bits in mask 0x3e and whose parallel class query 0x00534e10 is false, then rewrites that masked class field to 0x02 and widens the same cached bounds-and-count band [world+0x21c6..+0x21d6]. The next helper 0x0044ce60 scans the secondary raster at [world+0x2135] for cells with any bits in mask 0x3e, caching min/max bounds plus a marked-cell count in [world+0x21c6..+0x21d6]; the larger sibling 0x0044c670 then consumes those cached bounds to normalize the same raster and rebuild one dependent overlay/cache surface before the later route-style rebuild, shell-window, and briefing branches. That overlay side is tighter now too: after 0x0044c670 resolves scaled surface dimensions through 0x00534c50, it walks one local 3 x 32 sample lattice through the static offset tables at 0x00624b28/0x00624b48, keeps only secondary-raster classes 4..0x0d, folds several interpolated 0x0051db80 samples into one strongest local score, writes packed overlay pixels into the staged surface buffer, and only then publishes that staged overlay through 0x00534af0. The lower helper layer under that overlay pass is tighter now too: 0x00534e10 is the reusable secondary-raster class-set predicate for classes 1/3/4/5, 0x00534e50 is the smaller neighboring class-subset predicate for 1/4, 0x00534ec0 covers 2/4/5, 0x00534f00 covers 3/5, 0x00534e90 is the marked-bit query over the same 3-byte cell family, and the nearby local counter 0x0044bdb0 is now bounded as the 8-neighbor count companion for that same 2/4/5 subset, walking the shared 0x00624b28/0x00624b48 offset tables and re-entering 0x00534ec0 on each bounded neighbor cell. The first caller cluster around 0x0044bf9d..0x0044c37b therefore reads as a secondary-raster neighborhood service band rather than a generic map scan. 0x00533e70 and 0x00534160 are the coarser siblings over the overlay table at [world+0x1685]: the first clears coarse chunk objects across one clamped rectangle, while the second ensures one chunk object and seeds local marks through its deeper stamp helper. One level up, the neighboring rect owner 0x005374d0 now reads as the shared secondary-overlay refresh pass: it reruns the local sample and unsigned-word reducers 0x00536230/0x00536420, rebuilds the signed vector byte planes through 0x00536710, and then rebuilds the multiscale support surfaces through 0x00533890, whose inner reducers now explicitly target the packed sample-triplet buffer plus the float and unsigned-word support planes rooted at the five-entry per-scale families [world+0x15f1..+0x1601], [world+0x1605..+0x1615], and [world+0x1619..+0x1629]. The setup side of that same family is tighter now too: 0x005375c0 is the shared ensure-and-seed owner that allocates the sample, sidecar, mask, raster, vector, and coarse-cell tables together; crucially, it seeds [world+0x1655] with byte 0x02 and [world+0x1659] with byte 0x01, which closes the default-fill split. The local component-walk owner under the same neighborhood band is tighter now too: 0x0044c200 allocates a temporary width*height visit bitmap at 0x0062c128, seeds one class-2/4/5 starting cell, derives an initial direction index through the remap table 0x005ee5d4, and then fans into the deeper recursive walker 0x0044be20. That deeper walker widens dirty bounds [world+0x21ad..+0x21b9], stamps one companion-word orientation lane through 0x005ee5cc, reuses 0x00534ec0 plus 0x0044bdb0 to filter admissible neighbors, tracks temporary visitation in 0x0062c128, and then applies the local byte-1 edge-bit 0x04/0x08 updates before returning. So the 0x0044bf9d..0x0044c422 cluster now reads as a real connected-component walk plus edge-flag refresh layer over the secondary raster rather than only a loose group of local neighbor counters. The adjacent mutation strip is tighter now too: 0x0044dcf0 refreshes companion-word bit 0x200 in one local rectangle by checking whether any neighbor belongs to class set 2/4/5, while 0x0044df10 clears three local sidecar byte planes, demotes class 4 to 1 and class 5 to 3, and then reruns that marked-bit refresh over the surrounding +/-1 window. One level up, 0x0044e500 is the rect-wide owner that recomputes byte-1 edge bits 0x04/0x08 for class-2/4/5 cells, dispatches 0x0044df10 on incompatible local patterns, and finally consumes the pending global seed pair at [0x006d1304+0x78/+0x7c] through 0x0044c200. The shell-side owner of that pending pair is tighter now too: [0x006d1304] is the live PaintTerrain.win shell singleton while the callback-heavy side also keeps a second rooted pointer at 0x006d1334; the tool constructor snapshots the broader terrain-paint state into both families while the world-side raster owner still only consumes [0x006d1304+0x78/+0x7c] as one pending component-seed pair. Its radial sibling 0x0044e7d0 is narrower: after validating world-space coordinates through 0x00414bd0, it stamps class-2 marks into the secondary raster by walking one clamped bounding box and admitting cells only when the radial falloff helper 0x0051db80 stays positive before re-entering 0x0044c570. The two small support predicates under that same strip are now explicit too: 0x00414bd0 is the float grid-bounds gate, and 0x00449df0 is the integer rectangle clamp-and-validity helper shared by the local mutation owners. One level up, the broader rect-scoped owner is tighter now too: world_rebuild_secondary_raster_derived_surface_and_companion_planes_in_rect 0x0044e940 first reclamps the caller rectangle through 0x00449df0, reruns the local edge-refresh owner 0x0044e500, lazily ensures one presentation target through 0x0051f090/0x00534910/0x00534920/0x00534930: the first helper resolves the shared world-presentation owner, 0x00534910/0x00534920 expose the current staging flag and buffer root, and 0x00534930 captures one normalized-bounds rect into that staging buffer before the later publish step 0x00534af0. The same family then resolves scaled target dimensions through 0x00534c50 before allocating one temporary width*height mask. Its main scan then walks the live secondary raster [world+0x165d] through the same class predicates 0x00534e10/0x00534e50/0x00534f00/0x00534ec0: class-1/3/4/5 cells force 0xff into the four sidecar byte planes [world+0x1631..+0x163d], while the broader per-cell pass writes packed values into the ensured target through 0x00534730 and also updates nibble lanes at byte offsets +0x2 and +0x5 inside the same three-byte secondary-raster cell family. After the publish it notifies the shell owner at 0x0062be68, re-enters 0x00449f80 and 0x004881b0, frees the temporary mask, expands the caller rectangle by dirty bounds [world+0x21ad..+0x21b9] through 0x00536710, and finally seeds companion byte [world+0x162d] with 0xc4 on cells selected from mask plane [world+0x1655]. So the 0x0044e500 -> 0x0044e940 band is now a real derived-surface and companion-plane rebuild family rather than only a loose collection of local raster mutations. The local evidence now also supports a stronger negative conclusion: unlike [world+0x1655], that second mask plane is not part of the actively rebuilt runtime overlay path, and in the grounded local corpus it behaves only as a separately seeded, cleared, and persisted sibling plane. One level lower, the base-plane allocator 0x00532c80 now reads more cleanly too: it is the narrower owner that clears [world+0x15e1], optionally applies the current grid dimensions, allocates the base float-summary plane [world+0x1605], the four sidecar byte planes [world+0x1631..+0x163d], both one-byte mask planes [world+0x1655/+0x1659], and the packed secondary raster [world+0x165d], then seeds those planes with the same 0x02/0x01/0x00 default split. The load-side owner for those same planes is tighter now too: the constructor thunk 0x0044e910 immediately feeds the heavier payload body 0x0044cfb0, which reads the rooted chunk families 0x2ee2/0x2ee3/0x2ef4/0x2ef5/0x2ef6/0x2ee4/0x2ee5/0x2f43/0x2f44, allocates the core world-grid and secondary-raster arrays [world+0x2129..+0x2141] plus the route-entry collection 0x006cfca8, initializes every grid-cell record through 0x0042ae50, and only then hands off into world_compute_transport_and_pricing_grid 0x0044fb70, the neighboring presentation refresh 0x00449f20, and the shell-mode pulse 0x00484d70. So the 0x0044e910 -> 0x0044cfb0 load side is now bounded as the heavy world-grid and secondary-raster bundle-load body rather than just another anonymous constructor tail. One level higher again, the broader world-presentation reinitializer 0x00537e60 now sits above that base allocator and the larger support-family ensure path 0x005375c0: it stores the live grid dimensions, hard-resets the whole overlay runtime family through 0x00532590, and that reset strip is no longer opaque either: the immediately preceding local helpers 0x00532310..0x00532550 now bound one compact overlay-local state family under the same owner. 0x00532310/0x00532360/0x00532370/0x00532380 own the seven-dword companion block [world+0x15b5..+0x15cd] together with live flag byte [world+0x15b4]; 0x005323f0, 0x00532460, and 0x00532490 are the ensure, publish, and query strip for cached surface root [world+0x478] using saved dimensions [world+0x159c/+0x15a0]; 0x005324e0/0x00532500 are the live-flag setters for [world+0x159b]; 0x00532510 is the direct setter for mode byte [world+0x159a]; and 0x00532520/0x00532550 own the four-dword saved dimension quad [world+0x15a4..+0x15b0]. So the broader 0x00532590 reset really does sit at the base of a concrete local cached-surface and companion-block owner family, not just a pile of unrelated presentation fields. The reinitializer then reinitializes the secondary-overlay family for those dimensions, and then republishes the neighboring overlay constants and support owners used by both the world-side reattach branch and the .smp restore-side presentation rebuild path, including several owners that all funnel through the shared static-template slot allocator 0x00532ad0 over the local 0x100 pointer band at [world+0x08]. Those neighboring owners are tighter now too: 0x00535070 is the small primary overlay-surface-or-template setup owner; 0x00535100 is the heavier requested-dimension apply and four-slot overlay-surface rebuild owner used by the setup-side regenerate branch and the load-side bundle path; while 0x005356e0 and 0x00535890 seed two larger static-template slot bands rooted at [world+0x1568/+0x156c/+0x1574/+0x1578] and [world+0x1560/+0x1564] respectively; the remaining heavier sibling 0x00535430 now reads as a shared four-slot overlay-surface rebuild owner that resamples one source or fallback descriptor into a short local slot strip above [world+0x155c]. The immediate helper strip under that same family is tighter now too: 0x00534f60 is the small presentation-owner base init above 0x00532590; 0x00534f80 releases one transient surface handle at [world+0x478] and clears byte [world+0x159b]; 0x00532760 releases the current overlay slot chosen by selector [world+0x1558]; 0x005327a0 clamps two requested surface dimensions down to supported power-of-two sizes while also enforcing shell display caps from [0x006d4024+0x114243/+0x114247]; 0x00532860 is the local twelve-slot stitching pass over the parallel bands rooted at [world+0x08/+0x0c/+0x18], copying terminal rows and edge dwords between those sibling slot surfaces before finalizing the primary band through 0x00541c10; 0x00532960 is the adjacent paired projection helper that maps two caller counters through the current 16x16 and 4x4 rounded grid quanta and writes the resulting coarse offsets back to two out-pointers; 0x005329e0 maps one (x,y) pair into a 1-based coarse 4x4 overlay region id using the current rounded grid dimensions; 0x00532a30 is the direct getter for local dword [world+0x1554], which still reads only as the live count or tag for this overlay slot band; 0x00532a40 and 0x00532aa0 are the time-selected query helpers over the first and second template-seeded slot bands rooted at [world+0x1568/+0x156c] and [world+0x1560/+0x1564]; and 0x00532a90 is the direct getter for trailing fallback slot [world+0x1578]. The next adjacent owner is tighter now too: 0x00532b30 is the shared release/reset path for the local overlay slot band at [world+0x08], with a split release policy keyed by shell flag [0x006d4024+0x11422e] and a special forced-direct range for slot ids 1..0x10, after which it clears band fields [world+0x1554/+0x1568/+0x1570/+0x155c/+0x1560/+0x1564]. The tail of that same reinitializer is tighter one level up too: 0x00527ce0 is the broader ensure owner that watches current grid extents plus world tag [world+0x2121], re-enters 0x00532860 when those cached values change, rebuilds or releases local helper [this+0x65], and then clears the two large global scratch planes rooted at 0x008f2520 and 0x00b33530. The tail of that same reinitializer is tighter now too: after the larger support-family setup it seeds one seven-entry default overlay companion set through 0x005373b0, whose inner allocator 0x00535950 populates the local 0x1b-entry slot table from the static template rows 0x005dd300..0x005dd378. The lifecycle side is tighter in the same way now: 0x00536044 is the shared teardown owner that frees those same three five-entry support families together with both mask planes, the packed secondary raster, the vector-byte planes, the local staging buffer, and the neighboring sidecar or coarse-cell tables. The remaining base-float lane is tighter too: the larger rebuild owner 0x00538360 now clearly writes one base float-summary field into [world+0x1605], clears both one-byte mask planes, and then only repopulates the primary mask plane [world+0x1655] for the qualifying class-1 interior cells before re-entering 0x00532d90 to normalize that base float-summary plane globally and 0x00532f60 to expand positive cells through one caller radius. That asymmetry is now enough to close the local semantic edge: [world+0x1655] is the actively rebuilt primary overlay mask, while [world+0x1659] is only the separately seeded and persisted secondary mask sibling with no comparably grounded distinct read-side consumer. The only grounded getter call to its root accessor 0x00533b60 is the shell staging branch at 0x00525bad, and that branch immediately discards the returned pointer. The bundle side is now explicit too: .smp save-load treats the two mask planes as separate payloads with chunk ids 0x2cee for [world+0x1655] and 0x2d51 for [world+0x1659], while the neighboring 0x2d49/0x2d50 branches are the separate packed secondary-raster import lanes rather than alternate consumers of the second mask plane. So, in the mapped local code, 0x1659 is best treated as a persisted compatibility or seed-state sibling, not as a second actively consumed runtime overlay mask. The transport/pricing preview side is tighter now too: 0x00538060 sits directly beneath 0x0044faf0, first seeds one preview handle through 0x00535430 using the short C_ descriptor, temporarily overrides shell globals [0x006d4024+0x11423b/+0x11423f/+0x114254/+0x114255], and then loads %1.tga through 0x0053c1c0 -> 0x00541970. It clamps that sampled image into the 0x401 x 0x401 range, rewrites [world+0x1605] plus the mask/raster family [world+0x1655/+0x1659/+0x165d] from the sampled pixels, optionally re-enters 0x00532d90/0x00532f60, republishes the seeded preview handle through 0x0053c000, and then re-enters 0x005375c0(1, 0, 0). The small shell-global owner it also touches is tighter now too: 0x006d401c is constructed by 0x00538640, 0x005386e0 publishes the primary timed text lane, 0x005387a0 publishes the secondary fixed 10000 ms lane, 0x00538810 finds the first registered shell window containing one child control id by walking each window through 0x0053f830, and 0x00538840/0x00538880/0x00538890 manage the owner's local 1000-slot active-token table keyed by child control id. The adjacent list strip is tighter too: 0x00538990 is the registered-window virtual-slot-0 gate that stops on the first zero return, 0x005389c0 is the shared unlink helper for the same doubly linked list rooted at [owner+0x00/+0x04], 0x00538a60 is the zero-counter gate over [owner+0xc60], 0x00538a70 is the matching full reset-and-release body used during bootstrap teardown, and 0x00538a10/0x00538a20/0x00538a30/0x00538a40 are the direct getter, setter, increment, and clamped decrement helpers for the owner's scalar lanes [+0xc5c] and [+0xc60]. The next shell-runtime strip is tighter now too: 0x005388d0 is the shared 12-dword descriptor dispatcher with the optional override validator at [owner+0xc75] and the recursive kind 6 -> 0xb7 rewrite; 0x00538c70 is the prioritized cached-text owner over [owner+0xbd8/+0xbdc/+0xbe0/+0xbe4] that emits descriptor kind 0xae through 0x005388d0; shell_dispatch_synthetic_12_dword_descriptor_from_five_scalars 0x00538e00 is the five-scalar descriptor-synthesis wrapper above that same dispatcher; 0x00538e50 is the sorted registered-window insert owner over node key [node+0x21]; 0x00538ec0 is the refresh sweep over the indexed helper collection rooted at [owner+0xc69]; and 0x00538f10 is the broader optional-window publish plus blocking descriptor loop used by modal launchers and some shell transition paths.
