+# Archive 5 re-merge
+
+Baseline: the user's build at `ba92948`. Source archive: `crates (5).zip`,
+SHA256 `ca57392b5625f228a46d32cb10b3455f9946f6bfefefb08cfd649ac3706569d5`.
+The first attempt is retained on `lol/archive-crates-5-integration` for reference.
+The replacement is on `lol/archive-crates-5-selective`, rebuilt from the baseline.
+Previously reviewed adapter code was reused where it fits the agreed ownership;
+the archive was not applied as a replacement source tree.
+
+## Agreed ownership
+
+| Area | Decision |
+| --- | --- |
+| Off-board movement, board possession, mounting/landing | Archive systems |
+| Grinds, spline queries, material/family handling | Archive systems |
+| Powerslides | Archive runtime and settings |
+| Reverts | Archive fallback, explicitly selected by the user |
+| Manuals and FPS display | Add archive support |
+| Session markers and automatic bail recovery | Keep user's features |
+| Plants, boneless and handplants | Keep user's behavior; adapt query interfaces |
+| Scoring/HUD, crash reporting, outfits/custom models | Keep user's features |
+| Map management, multiplayer, menus, replay | Keep user's features |
+| Pose sampling, authored clip overrides, blend-space evaluator | Keep current implementation |
+
+The archive redirects `RevertGround` requests to ordinary ground physics; it
+does not supply a dedicated revert solver. That fallback is intentional in this
+merge. The previous revert owner is not entered through normal state selection.
+Powerslide runtime, update and settings files match the archive.
+
+## Integration details
+
+The new off-board/grind owners use the current marker and respawn services.
+Manual marker returns retain the saved on/off-board state and clear pending
+physics work. Manual markers and automatic bail checkpoints remain separate.
+Plants query the new spline/trajectory interfaces. Multiplayer collision
+publication reads the new per-part board-volume state. Optional climbing resumes
+through the new off-board contact owners.
+
+The preservation audit found 46 feature files unchanged from `ba92948`, and
+eight adapter files changed: boneless launch, climbing approach/test queries,
+footplant ground/edge queries, handplant queries, network collision publication,
+and automatic-respawn observations. Shared frame/state coordination also adapts
+these retained features to the archive owners; unchanged feature files alone do
+not prove runtime compatibility.
+
+The user's interpolated animation/replay presentation function is unchanged.
+Only the archive's independent skater-culling fix was added around it. Existing
+native bump Begin dispatch/arithmetic, decoded-key sampling, authored clip
+replacements and weighted blend arithmetic remain. Unsupported stock predicates
+are not replaced with guesses, and optional unsupported branches retain explicit
+lazy diagnostics. The silent archive deck-angle no-op remains an explicit error
+if reached.
+
+Collection lookup accepts both readable and numeric AttribSys names. This fixes
+the first build's `Missing stock collection anim_motion/manual` initialization
+failure without changing or regenerating assets. Two data-only regression tests
+passed in the investigation; a static audit resolved 157 literal lookups against
+the prepared 6,849-collection export, including payload sizes.
+
+## Validation and private build
+
+`cargo check --workspace --tests --release --no-default-features --offline`
+passed for the reconciled owners. Gameplay tests were compiled, not executed.
+The final Windows executable is linked directly to an ignored private filename
+with explicit `/OUT` and `/PDB`, using the shared target cache and static CRT.
+The launcher is updated only after successful linking and PE/PDB provenance
+inspection. The ignored build manifest records the exact source revision/hash.
+
+The existing prepared customiser assets, ten maps, scoring HUD and marker overlay
+are reused. No ISO extraction, Blender, clean build, game launch, Steam session,
+push, merge into the main branch, or release is performed by this task.
+
+## Manual checks
+
+1. Start University and resume; check that initialization completes, the avatar
+   remains visible and the HUD/FPS display appears.
+2. Push, steer, brake, ollie, flip and manual. Try powerslides in both directions
+   and at low/high speeds; watch for sudden spins, loss of control or stuck poses.
+   Try revert input too, remembering this build uses the archive's fallback.
+3. Dismount, run, jump, fall, throw/retrieve and remount. Watch for floating feet,
+   immediate landing poses, board separation and unexpected bails.
+4. Enter/exit grinds from both sides; exercise plants, handplants and boneless.
+   Check for missed contact, abrupt launches and states that fail to end.
+5. Set a marker with LB + D-pad Down and return with LB + hold D-pad Up, on and
+   off the board. Bail separately; confirm the manual marker is not overwritten.
+6. Change maps, difficulty and outfits, then repeat recovery checks. Check replay
+   interpolation and multiplayer appearances/contacts in a prepared session.
+
+Report failures with the diagnostic report, map/difficulty and last controller
+action. Compile and source-preservation checks do not establish gameplay parity.
