+State loading resets unsaved renderer history. A 400-frame X3 crossing,
+sampled every four frames against native width, has zero unexplained pixel
+differences after excluding relocated HUD pixels and the hidden 16-pixel face.
+
+The original Bit/Byte fall routines defer terrain collision until
+`cameraY+$98/$78`. A vertical approach can put that plane below the floor;
+the initial bad landing was also reproduced with the original ROM in Snes9x.
+Use the original stage record to begin collision by `recordY-8`. Collision
+chooses the actual landing; camera, actor coordinates, velocity and result
+flags are not forced. Bit needs its later `$98` operand compensated as well.
+Only `$07:907D` and `$3C:C588` receive this policy. Their interpreter hooks
+validate the original bytes and complete the 16-bit LDA with its original
+five slow-bus cycles and flags. No mutable ROM operands or extra serialized
+state are required.
+
+Generated reinjection now has 32 marked sites: the existing 30 horizontal
+sites/12 pairs, plus these two landing reads, and four separate streamer
+sites. `tools/test_hunter_landings.py` replays the before-door snapshots,
+observes both initial landings and active combat, and refuses already-started
+or completed setups. Byte lands at world Y663 and Bit at679, with visible feet
+at703 against floor704 (the normal collision inset), instead of695/727.
+Hybrid342, pure-interpreter684 and native256 checks pass. Owner floor/door
+acceptance is still pending; prior failed notes are retained individually.

+Hybrid342, pure-interpreter684 and native256 checks pass. The owner accepts
+Byte's floor, grab/recovery and exit, and confirms a single door face. The
+remaining moving-door garble was traced separately to checkpoint preparation.
+
+### Checkpoint graphics prerequisites
+
+A direct stage-8 checkpoint-1 load selects graphics group4, which assumes
+resident door asset `$56` from earlier group1. The prepared approach omitted
+that prerequisite: `$7F:8256/$7F:8356` remained zero. The original `$01:E065`
+door initializer cached those zeros and its animation referenced X's tiles.
+Unmodified Snes9x reproduces the same garble with this incomplete setup. The
+earlier native-width comparison only demonstrated renderer agreement; both
+widths shared the missing graphics, so it did not establish authentic art.
+
+`tools/hunter_approach.py` prepares the prerequisite through the original
+`$00:B1FC` cooperative graphics job, loading group1 then restoring group4
+before the room door initializes. It leaves actor/camera/collision/result
+state to the original game. This explicit assist bypasses earlier traversal;
+it does not validate the skipped graphics-group transition. The loaded base
+is `$F0`, attributes `$2F`, and the door CHR is identical to the independent
+original-ROM reference. Both the replay and owner-selector guards reject a
+missing asset or an existing room door with stale cached graphics fields.

+### Locked Lab 1 arena margins (2026-10-27)
+
+The Lab 1 end room exposed its neighboring corridor on the left and unbacked
+map space on the right at very wide aspects. Its original locked bounds
+`1600/0600/0600/1600/1600`, mode 1 and maps `$50/$58` now reuse the existing
+Sigma wall-edge compositor and BG2 containment. The approach keeps its normal
+streaming until the original room lock completes. No guest state is changed.
+
+Paired native256, hybrid342 and interpreter684 runs plus the actual 360-frame
+door approach preserve every native-view pixel, all 128 KiB WRAM and 64 KiB
+VRAM in 48 samples. Byte420, factory360, Kaiser120, hub120 and native rematch
+entry120 preserve complete output and WRAM against the preceding build.
+Refreshed Kaiser and all-clear hub states each replay 120 frames identically
+after current-build save/load. This qualifies presentation; alternate branch
+selection, full Lab 1 combat and its following transition remain separate.

+
+### Godkarmachine and Doppler follow-up (2026-10-27)
+
+The lower Lab 1 checkpoint2 room and Doppler's real stage12 checkpoint2 end
+room have the same boundary problem. Their original locked bounds
+`1600/0700/0700/1600/1600` and `0a00/0400/0400/0a00/0a00` join Press and Sigma
+in one explicit descriptor table. All four use the existing wall compositor;
+ordinary corridors and native framing retain their previous policies.
+
+God/Doppler native256, hybrid342 and interpreter684 provide 48 paired samples
+with identical native-view pixels, full WRAM and all 64 KiB VRAM. Native entire
+output is identical. Byte420, factory360, Kaiser120, hub120, rematch entry120
+and Press120 preserve complete output/WRAM against the preceding build.
+The actual post-Doppler clear also reaches its password screen after 900
+frames with identical complete output/WRAM. Both current handoff states replay
+120 frames identically after save/load.
+
+Separate assisted combat runs now qualify live32HP Godkarmachine, Press
+Disposer and Doppler, actual projectile defeats after HP assistance, and
+native fortress counters `0->1` or `2->3`. God needs20 original dialogue
+edges to transform; Doppler needs54 before combat and54 after. Press's
+trunk and head are separate phases; aiming24 pixels above the parent origin
+finishes the head. These mechanics runs retain the exact preceding28f17ee
+binary identity; the new33949e75 executable adds only the presentation cases
+and has the paired checks above. Private evidence lists all bypasses.
+
+Checkpoint2/3 selection bypasses Lab 1's original branch fork. Position
+assists bypass ordinary corridor obstacles before Doppler's real door.
+Normal fortress next-stage selection remains unverified: repeated Start
+after the password loads stage0, and restoring the native fortress entry
+marker alone did not resolve it. No game defect or speculative marker fix is
+claimed. An authentically completed intro/normal-selection baseline is the
+next setup investigation. Lab2 branches and Kaiser/escape/ending remain open.

 Checkpoint2/3 selection bypasses Lab 1's original branch fork. Position
 assists bypass ordinary corridor obstacles before Doppler's real door.
-Normal fortress next-stage selection remains unverified: repeated Start
-after the password loads stage0, and restoring the native fortress entry
-marker alone did not resolve it. No game defect or speculative marker fix is
-claimed. An authentically completed intro/normal-selection baseline is the
-next setup investigation. Lab2 branches and Kaiser/escape/ending remain open.
+The earlier fixture did not qualify normal fortress next-stage selection.
+The clean native-context follow-up below supersedes that setup limitation;
+no speculative marker or progression fix was adopted.
+
+### Native fortress progression follow-up (2026-10-27)
+
+Controller-only password entry and original stage selection now provide a
+clean baseline with earlier progress and equipment initialized by the guest.
+The reference password reaches normal stage select in hybrid342 and pure
+native256. An independent Snes9x replay reaches the same screen with identical
+64 KiB VRAM; an unchanged menu mode is normal while awaiting input.
+
+On current33949e75, the original checkpoint3 loader preserves this native
+context and bypasses only Lab1 traversal/branch selection. Press starts at
+32 HP; the main/trunk survive idle at assisted1HP, then real shots destroy
+both. Original stage-clear, counter0->1, password, stage select and next
+laboratory selection pass without progression writes.
+
+The native selection chooses stage14's Vile branch. Checkpoint2 bypasses
+earlier traversal; right input then exercises the first door, descent, second
+door and armor introduction. Actor99's real defeat creates on-foot Vile
+actor97/sub2 at32HP. Each survives an idle check at1HP before real shots
+produce its native defeat. Twenty-three B edges finish the postfight script;
+the native stage-clear reaches counter1->2 and its password screen. Early
+private captures provisionally named this encounter Volt; the observed second
+form and corrected aggregate identify the Vile branch. Those filenames are
+historical evidence, not alternate boss coverage.
+
+The next native selection enters stage12/counter2. The all-clear hub fixture
+also now opens its real right door into the corridor. Original39:A2D0 caches
+`1FDA==FF` into door prerequisite `1F5F` bit0 at initialization: supplying FF
+after initialization leaves the cached gate locked. Reinitializing with the
+prerequisite already present naturally clears it. Player-only flight reaches
+the upper platform and native gravity lands atY1119 before real right input
+opens the door. The eight earlier rematch results are an explicit prerequisite
+bypass here, separate from the retained ca0 actual-eight-rematch proof.
+The optional human hub check is retired; owner notes remain unchanged.
+
+Position assists then bypass ordinary corridor obstacles before Doppler's
+original door. Native32HP, causal1HP idle check, real defeat and54 postfight
+B edges reach counter2->3. Password and normal stage selection now enter
+final stage13 without additional stage/counter/main-weapon writes. Its original
+Zero approach/dialogue also returns control after18 B edges.
+
+This adds current-build combat and normal progression evidence without
+claiming the skipped approaches or the other Lab2 branch. Kaiser/escape/ending
+and built-runtime/other-consumer qualification remain open.
+
+The final title code8a71 also passes paired checks on combined engine2cb versus
+ownera4: Byte420, factory360, God/Doppler/Press/Kaiser120 each, and the corrected
+hub exit300 at342, native256 and interpreter684. All144 samples preserve the
+complete presented image and128KiB WRAM; all three hub cases cross the door.
+Compiler definitions confirm both trace builds use FULL audio history despite
+the earlier cache-based SMALL/FULL inference. Performance remains a separate
+measurement gate; these functional comparisons establish no speed claim.

+### Other Lab2 route and room boundaries (2026-10-27)
+
+The other native Lab2 selection now has separate coverage. The earlier Vile
+prerequisite is supplied before original stage selection; checkpoint2 bypasses
+the approach. Native256 and interpreter684 follow the same780-frame original
+door/descent/introduction timeline, create actor4A at32HP, and advance the native
+fortress counter1->2 after an assisted1HP idle check and a real shot. No current
+success, camera, control or other boss-part HP is written.
+
+This route revealed a512px room whose expanded margins exposed a neighboring
+corridor, black void and a wrapped BG2 boss copy. BG1 now reflects only beyond
+the authored room. A shared PPU clip band contains BG2 using BG1 actual scroll,
+retaining the real body in genuine offscreen room columns. It preserves native
+camera-shake pixels and clears with the normal frame-local presentation policy.
+
+Final758756b9 passes72 paired samples at256/342/684, centered and at both camera
+edges: every native/authored-room pixel,128KiB WRAM and64KiB VRAM matches339.
+The900-frame entrance probe compares rendered output and observes no correction
+while the entrance door is visible. The full-health entrance, real-shot clear
+and current-build save/load pass. Eight unrelated scenes preserve complete
+output and WRAM over112 paired samples, including accepted Byte/factory,
+God/Press/Doppler/Kaiser, the corrected hub exit and the other Vile route.
+These checks do not qualify skipped traversal, the Kaiser finishing hit,
+escape/ending, independent audio or the remaining human visuals.

+### Refreshed engine base (2026-10-27)
+
+Reviewed engine0095609 is rebased onto main5ac4b98 and has the same tracked
+tree as compiled combinede772aca and integrationa99e2fc. The title now pins
+this engine. New buildc3d20fc6 passes156 paired full-picture/WRAM samples
+against preserved95ad, including Byte/factory, the fortress rooms, hub exits
+and684px Lab2 pans. Its sampled Press PCM and full SPC state match byte for
+byte in default and pure execution. Current save/load, Pause/Capture and the
+refreshed live1HP Kaiser setup replay exactly.
+
+The package selects native APU time and SLICE8 CRC with the standard title
+renderer. Six paired240-frame samples in each execution mode are small and
+mixed within host variation: neutral/inconclusive, with no broader speed claim.
+Warm startup and memory costs are effectively unchanged. Earlier combat and
+renderer proofs keep their original binary identities. The four pending
+human checks are unchanged; accepted Byte/doors/factory checks are preserved.
+Kaiser finishing hit/escape/ending, skipped content/independent audio and
+broader-consumer follow-up remain open. Exact data is in `new_main_qualification`.

+### Native final-room trigger qualification (2026-10-27)
+
+On current c3d20fc6, the clean native fortress route now reaches the
+original upper-room cue, full32HP Sigma introduction, real projectile
+defeat and full32HP Kaiser introduction/control return. Native256/default
+and684/interpreter repeats pass the same cues; introductions take22 and36
+B pulses respectively. Combat hit timing is not asserted equal.
+
+Actual ladder grabs/climbs and connector traversal work. Position-only
+alignment and flight bypass ordinary shaft/wall-jump traversal; main
+Sigma HP1 survives idle before the real hit. No camera, AI, progression
+or result flags are written. The hit changes a mutable parameter byte;
+stable actor-slot/id proves HP0/primary04 and corrects a false helper
+failure. Original raw output and excluded setup experiments are retained.
+
+Current Kaiser save/load and Pause/Capture/restart are exact in full
+pixels and128KiB WRAM. Captures now include actual generated-CPU
+registers. Kaiser finishing hit, escape and endings remain unverified;
+the existing optional human segment remains available. See
+`native_final_qualification` in the audit JSON for assists and evidence.

+### Fixed epilogue and assisted aftermath (2026-10-27)
+
+The opening ending scene repeats its sun and factory at wide widths.
+Code87f198e retains the authored256px composition only for ending
+mode6/phase0, reusing the existing frame-width hook. The scrolling
+cast returns to adaptive widescreen in phase2. Gameplay is unchanged.
+
+New3435c017 at342/default and684/interpreter preserves every native
+epilogue pixel and128KiB WRAM across20 samples/6000frames per mode.
+The cast restores full width and identical whole output. Actual clear
+entry, four current-state replays, the portable debug-host regression,
+Byte/factory/Kaiser/hub samples and current Kaiser Save/Pause/Capture
+also pass. Source generator/core/package settings are unchanged.
+
+The preceding c3d2 audit now exercises original virus creation, rising
+lava/camera, contact/recovery, upper corridor, Zero rescue/dialogue and
+counter3->5/ending mode6 at342 and684. A further24000 no-input/no-RAM
+frames at342 reach Thanks for playing / Presented by CAPCOM. Kaiser
+HP0 deliberately bypasses the unverified finishing hit. Position assists
+bypass wall-jump traversal and correct an entry below a raised ledge;
+no camera, AI, progression, escape or ending flags are written. The
+same low prepared entry stalls natively too, so it is excluded as a
+demonstrated widescreen defect. Real finishing hit, uninterrupted
+physical escape and alternate rescue ending remain unverified. Exact
+binary identities and caveats are in `epilogue_and_aftermath_followup`.

+### Maoh object canvas and shared presentation follow-up (2026-10-27)
+
+Maoh uses BG1 for its roof, BG2 for a moving boss canvas and BG3 for the city.
+The scoped stage0 policy keeps live boss tiles, hides unrelated circular-map
+cells, widens the genuine skyline and repeats only32px world-edge strips
+beyond the combat roof. Real in-room damage remains; outer margins no longer
+reflect another door, boss or destroyed floor. Codee5e5f15 pins engine05786e5.
+
+Build10994be1 passes fresh opening, original full32HP introduction, assisted
+real projectile defeat, native clear/stage-select and controller next-stage
+load at256/default,342/default and684/interpreter. All93 sampled native
+pictures/WRAM/VRAM/OAM agree with3435; six current live/selection replays
+match exactly. Connecting travel and HP1/aiming assists remain explicit.
+
+The shared X2/X3 package passes188 full-output/128KiB WRAM regression
+samples, non-silent PCM/full SPC/APU comparisons, and all four prepared
+states’ save/load and Pause/Capture/restart checks. Accepted Byte/doors/
+factory observations remain closed. Per-game timing samples are small
+and mixed: neutral/inconclusive, without a speed claim. Actual trace is
+FULL in these diagnostic builds despite the SMALL cache request.
+Remaining human/content/branch/audio gaps are unchanged; see
+`maoh_object_canvas_followup` for precise identities and bypasses.

+### Final-stage entrance camera (2026-10-27)
+
+Buildd897f993 reuses the parked X1 view-anchor mechanism in engine819e2e1.
+At the demonstrated final-stage entrance, the extra columns go inside the
+room, removing the unused strip to its left. Native camera/scroll/OAM and
+sequence state are unchanged. HUD and dialogue retain screen coordinates.
+This is scoped to the measured chamber and internal widths up to512;684
+retains the previous centred policy because its one-sided ordinary OBJ span
+exceeds512. Other rooms and wider anchoring remain separate work.
+
+Twenty-five controller-only movement samples retain the complete native
+picture outside the existing HUD footprints and exact128KiB WRAM. The
+observed image origin moves from0 to43 as X leaves the wall. Kaiser, escape,
+Byte and factory retain whole output/WRAM in68 samples. Native256 and
+684/interpreter remain unchanged in16 samples. Current-build entry/Kaiser
+save/load and Pause/Capture/restart checks pass; seven PPU fixtures pass.
+One initial unsettled Byte picture is retained as an inconclusive observer
+sample; the independent settled replay passes every sample.
+
+The unmodified Snes9x reference confirms the entrance composition and the
+original shaft pipe walls. Static shaft-art inspection uses explicit camera
+positioning and does not certify an independent original escape sequence.
+The walls above the fire are authored background art. The owner separately
+accepts the absence of a duplicate Kaiser head. Actual finishing-hit,
+ordinary escape and other pending audit gates retain their own status.

+### Earned Zero-loss finale and current Bit follow-up (2026-10-27)
+
+Build d897f993 passes the fresh final-stage route at 256/default, 342/default
+and 684/interpreter using the earlier naturally earned Zero-loss fixtures.
+The original loader preserves that result; real Sigma damage, full Kaiser
+introduction, actual virus damage, original top-camera arrival, controller
+wall jumps over the raised ledge, alternate rescue, native counter 3->5/clear
+and ending all execute. All three ending save/load replays preserve the
+complete output and 128 KiB WRAM. Cross-width timing equality is not asserted.
+
+Earlier fortress eligibility and connecting travel/shaft ascent are assisted.
+Kaiser HP=0 explicitly bypasses the finishing hit, which the owner has already
+qualified separately. After selecting earlier fortress eligibility, no
+unavailable, camera, AI, current encounter outcome or later progression flags
+are supplied; no writes occur after the native clear.
+The earlier actual-loss fixture retains its 10994 identity. This closes fresh
+loss-result propagation, not ordinary whole-stage traversal.
+
+Current Bit also passes original floor contact at Y=679 (feet=703, floor=704,
+camera Y=559), full 32 HP introduction, a real assisted Buster finishing hit,
+native departure/result 01, right-door crossing and normal control return.
+The before-room floor-only owner setup includes original resident door art.
+Only Bit floor appearance awaits human confirmation; no accepted Byte,
+door, camera, Kaiser, factory or X2 check needs repeating.
+
+Very-wide entrance anchoring above 512, uncovered stage/sublevel/branch/exit
+travel, independent original-game music/SFX and broader shared-engine consumer
+qualification remain open. Machine-readable current_status is authoritative;
+older identity-specific remaining lists describe their historical milestone.

+
+### Producer coordinates for very-wide entrance views (2026-10-27)
+
+The private candidate now anchors the final-stage entrance at684 and800px.
+It observes full signed X at the original CX4 microcode write02:80E6 and
+binds it to the actual OAM XY upload. An exact microcode signature guards
+the policy; guest camera, OAM, collision, AI and progression stay untouched.
+Pending and uploaded positions travel through the title save/rollback extension.
+The shared desktop host also retains the16-bit budget: casting272 to eight
+bits previously collapsed800px output to288px.
+
+All nine PPU fixtures and the synthetic original-instruction observer pass.
+Forty-six runtime samples retain full WRAM/VRAM/OAM equality;256/342px full
+images match the accepted build in entry, Byte, factory and Kaiser workloads.
+At684/800 the corresponding native world pixels below the HUD match; actual
+800px output replaces the baseline288px wrap. Current-build full-image/WRAM
+save/load replays pass at342,684 and800. Matched342px runtime samples are
+inconclusive on the shared host (median+3.14%, range-2.64%..+5.05%);
+this is not a speed claim. Raw evidence is `cx4-coordinate-qualification.json`
+in the retained audit workspace.
+
+The current owner build remainsd897 and all prepared human checks are accepted.
+Full very-wide chamber travel/transitions, uncovered
+content/audio and broader engine qualification remain before release.
+
+Image inspection also exposed a moving61px BG2 strip outside its slower
+parallax canvas. Very-wide anchoring now stays within both BG layers. The
+repeated46samples and three current-state replays pass;<=512 placement
+retains its accepted behavior. No new owner check is prepared.

+### Native OBJ quotas and the connecting fortress route (2026-10-27)
+
+Busy wide margins were consuming the native32-object/34-sliver quotas. The
+private3368 build keeps margin work outside those quotas while retaining
+authentic native overflow, OAM order and the explicit NoSpriteLimits option.
+The old evaluator fails eight synthetic assertions across both renderers; all
+nine PPU fixtures now pass. Twelve exact corridor inputs match zero-extra
+native OBJ pixels and overflow flags below the HUD. The observed missing
+native pixels (3,10,3 in three samples) are repaired.
+
+Thirty-eight paired samples retain whole images and full WRAM/VRAM/OAM at
+256/342 in entry, Byte, factory and Kaiser scenes. Three current-build image/
+WRAM replays pass, including full32HP Kaiser at800. The assisted800 route
+now crosses the corridor, both ladder transitions and the long shaft into
+full32HP Sigma, an actual HP1-assisted Buster defeat, and full32HP Kaiser.
+All119 sampled route states retain paired WRAM/VRAM/OAM equality. Traversal
+positions, health and protection are assists; ladders/dialogue/boss damage run
+on original controller input. No camera, AI, control or result flags are set.
+
+Matched diagnostic cost samples retain neutral native256 throughput. The busy
+342 workload measures median+4.02% (+0.003..+0.199ms/frame) while rendering
+required sprites the old quotas discarded.800 measures-1.72% on the shared
+host; it does not offset the342 cost or establish an optimization win. Slowest
+observed candidate throughput is170fps. Broader consumers remain a separate
+gate. Raw evidence: `native-quota-qualification.json`.
+
+The connecting route exposes a separate unresolved issue: unused background
+space and out-of-room projectiles beside the vertical travel rooms, including
+the full43px right gutter at342. `beads-8wg.19.5` owns that fix. Trigger
+progress does not clear this visual failure. The owner build remainsd897,
+all prepared human checks stay accepted, and no release/handoff is made.

+### Bounded final-fortress travel canvas (2026-10-27)
+
+The connecting shafts now continue their authored outer wall pixel into
+overflow gutters. Bounds come from the loaded BG1 screen rows, preserving
+intentional transparent cells and genuine offscreen terrain. The two visible
+source rows can have different spans. BG2 retains its live circular canvas,
+including negative logical Y; BG2 and guest OAM are clipped outside the room.
+Configured HUD slots and native OBJ quotas remain intact. The accepted
+entrance anchor and closed boss policies retain ownership. No camera, AI,
+collision, encounter-result or progression value is replaced.
+
+Native256/342/684/800 static comparisons and moving342/684/800 ladder/shaft
+routes preserve native pixels and full WRAM/VRAM/OAM. Bit, Byte, factory and
+the entrance retain their full342px output in automated regression; all three
+current-build shaft save/load replays pass. Nine PPU fixtures pass; the new
+guest-OAM clipping assertions fail on the preceding engine, across both
+renderers. Before/after images show the342px brown gutter and stray projectile
+replaced by wall continuation, including the wider source-row transitions.
+
+This resolves the demonstrated canvas gap in `beads-8wg.19.5`; it does not
+qualify skipped stage/sublevel/branch/exit travel or independent original
+music/SFX. Raw qualification and matched diagnostic cost samples are retained
+in `fortress-travel-qualification.json`. This is a correctness change, not an
+optimization claim. The owner runtime remainsd897, all prepared checks remain
+accepted, and broader engine consumer/final merge qualification stays open.
