Stage Catalog Fortress

Fortress stage catalog

Scope: Stage-local catalog for Fortress, compact selector 7 / native stage ID 9. Shared record grammar, resource notation, evidence labels, and safety rules are owned by Stage catalogs. General extension-selector/materializer mechanics and composed-proof chronology remain owned by Global item materialization and solvability.

Stage identity and evidence

• Static-confirmed: all 9 ordinary pickup records, all 7 stock outer slots, and the recognized resource records below are decoded from the clean USA N64 ROM.
• Runtime-confirmed: the complete Fortress resource file was byte-matched against captured runtime memory at 0x801F4E20.
• Runtime-confirmed: representative Fortress ordinary-pickup collection/persistence is established, but all 9 Fortress records have not been individually exhausted one by one in runtime testing.
• Runtime/user-observed + Static-confirmed trigger ownership: the three crystal reward records are spawned after defeating Kia, Jataaka, and Sareena. Fortress overlay file 0x9E statically couples encounter indices 0/1/2 to the first three 0x30 pickup records and activates each record after the matching assassin encounter. For randomizer semantics these are three boss-defeat reward locations; the crystal identity is the stock reward, not a permanent binding between boss and reward.
• Runtime-confirmed, proof-only (2026-09-30): the Fortress five-import stress ROM replaced the first five stock Herbs locations with Potion, Urn of Vitality, Formula, Eye, and Shield while retaining the sixth Herbs record byte-for-byte as a control. Manual validation confirmed Fortress loaded normally; all five imported visuals rendered correctly and awarded the expected items; the control Herbs remained normal; and no rendering, audio, stability, or stage-progression regression was observed on the tested route.
• Runtime-confirmed, proof-only (2026-09-30): Kia's boss-defeat reward record 0xC4834 was changed from Crystal Kia to a Potion while preserving the boss-owned 0x8000 activation gate in +0x14. Manual validation confirmed no Potion reward existed before Kia's defeat; defeating Kia activated the replacement reward at the boss location; the model rendered as Potion; collection awarded Potion rather than Crystal Kia; and the encounter/stage remained healthy on the tested route. This confirms reward identity can change independently of the Fortress boss trigger on this bounded case.

Fortress-specific notes, constraints, and proof-local evidence

• Checkpoint/progression static closure (2026-09-29): the stock Fortress crystal records use generic callback 0x80038770, but its stage-9 branch awards IDs 0x20..0x22 and acquired bits without taking the generic direct 0x80062D60 presentation request or pickup-created 0x802C18F8 selector-write branches. Crystal USE dispatch entries map to position-gated progression handlers 0x8007239C / 0x80072400 / 0x80072464, which commit bits 0x08/0x10/0x20 in 0x802C0D54. The stock crystal award path is therefore Static-confirmed checkpoint-free. The remaining Fortress blocker is different: each boss-defeat reward location must materialize/award whichever logical item the global layout assigns while preserving the boss trigger.
• The stock resource file has exactly 7 occupied outer slots. Its outer table occupies file-relative 0x0000..0x001B; the first descriptor starts immediately at 0x1C. There is no empty stock logical selector.
• Adding an eighth stock-table word in place would overwrite that first descriptor. This is a Static-confirmed stock-layout fact, not a claim that Fortress lacks all ordinary-pickup selector expansion paths.
• Slot 5 aliases the Herbs descriptor 0x1338 used by slot 3. Slots 4 and 6 have no ordinary-pickup users, but all three remain protected until other Fortress actor/script references are resolved.
• Bit-15 activation-gate closure (2026-10-02, Static-confirmed; Kia replacement Runtime-confirmed): the crystal parameters 0x8000/0x8001/0x8002 use the same destination-record activation gate established generically in the Bridge audit. Pickup-manager setup consumes raw bit 0x8000; callback dispatch masks it away. Fortress encounter manager 0x802EFDB0 clears that bit only on the indexed boss reward record after the corresponding assassin completes. The low 15 bits remain the logical crystal index/ID input to the stock callback.
• The first three catalog rows describe the stock spawned rewards for the Kia/Jataaka/Sareena boss checks. Static overlay trace now resolves the exact association: ASSASSIN1/type 0x0D -> Kia record 0xC4834, ASSASSIN3/type 0x13 -> Jataaka record 0xC4864, and ASSASSIN2/type 0x1C -> Sareena record 0xC4894. The manager copies the defeated actor X into record +0x00 and clears the 0x8000 bit in record +0x14 to activate the indexed reward. The final global materializer must preserve this trigger while allowing any assigned logical item identity in the reward record.
• Fortress selector/checkpoint ownership closure (2026-10-02, Static-confirmed): raw Fortress overlay file 0x9E is ROM [0xC0330,0xC4C70) at runtime base 0x802ECE30. Direct global-selector writes in this overlay are: selector 9 during an initialization/re-entry path at ROM 0xC044C; selector 5 at 0xC28FC, selector 6 at 0xC2938, selector 8 at 0xC2998, and encounter-index-derived selector s4+2 at 0xC38B0. None of the nine ordinary pickup callbacks write 0x802C18F8.
• Boss-defeat checkpoint binding (2026-10-02, Static-confirmed): encounter manager 0x802EFDB0 handles indices s4=0/1/2. On completion it writes selector s4+2, producing 2/3/4, and separately records the completed encounter mask and activates the corresponding gated reward record. Fortress spawn-table selectors 2/3/4 at 0x800A01BC/0x800A01D0/0x800A01E4 have X/Y coordinates 0x00047300/-0x00054000, 0x00194900/-0x000A8000, and 0x00414E00/-0x000FC000, exactly matching the three encounter-table centers in 0x802F15B8 + index*0x18. Therefore those checkpoint/state advances are boss-encounter-owned, not reward-pickup-owned.
• Crystal-use progression/checkpoint binding (2026-10-02, Static-confirmed): permanent use handlers 0x8007239C / 0x80072400 / 0x80072464 commit progression bits 0x08/0x10/0x20 after player-position checks. Fortress overlay state machine 0x802EF30C consumes (0x802C0D54 >> 3) & 7 and maps progression states into later native selector/checkpoint states: 5, 6, and 8, each through a stock 0x80062D60 presentation path where applicable. The position windows for the first two USE handlers center on selector-5 and selector-6 spawn coordinates (X=0x000A8000 and 0x003C0000); the third USE zone centers around X≈0x0023FC00, adjacent to selector-7 spawn 0x00240000, while the completed third progression route advances onward to selector 8. These are native progression/use semantics, not ordinary reward-location semantics.
• Accepted Fortress destination contract (2026-10-02): none of the nine ordinary Fortress locations needs a checkpoint wrapper. The six stock Herbs locations have no identified destination activation/checkpoint side effect. The first three boss-reward locations retain only their destination-owned bit-15 activation gate and encounter-controlled X relocation; the assigned logical reward is materialized/awarded independently. Logical crystals remain checkpoint-free inventory rewards; their later USE handlers and Fortress progression/checkpoint state remain stock-owned. The shared materializer's generic destination-gate preservation already represents this contract.
• Composed five-import stress construction — Runtime-confirmed, proof-only: the disposable proof replaces the first five stock Herbs locations with Potion, Urn of Vitality, Formula, Eye, and Shield, retains another Herbs record byte-for-byte as a control, and supplies five contiguous extension-selector entries plus self-contained imported bundles. Manual runtime validation confirmed the five models/awards and untouched Herbs control in Fortress with no observed rendering, audio, stability, or progression regression on the tested route. The generalized construction details remain on Global item materialization and solvability.
• Fortress ordinary-location ownership is now statically closed for all nine records. The shared materializer already generalizes destination bit-15 preservation across all three assassin reward records and keeps logical crystal awards separate; the Kia substituted-reward route is Runtime-confirmed bounded evidence. Remaining work belongs to whole-system wrapper/integration validation rather than more Fortress ownership research.
