Inline comments:
In `@docs/reference/akr-archives.mdx`:
- Line 279: Update the archive documentation sentence to refer to “Current v11
local StartPos saves” instead of v10, keeping the surrounding import and
recreation guidance unchanged.
In `@docs/reference/snapshot-bundle.md`:
- Line 5: Update the local reconstruction snapshot version statement to document
the v11 contract, including that the current format is akron-reconstruction-v11
and older slots must be recaptured.
In `@docs/startpos-restore-verification.md`:
- Line 226: Remove the machine-specific absolute path from the verification
documentation and replace it with a repository-relative path or neutral
verification-workspace description, preserving the surrounding verification
guidance.
In `@scripts/akron-verify/map-sweep-bulk.sh`:
- Line 141: In the launch flow of the bulk sweep script, create or refresh
/tmp/akron-bulk.marker immediately before starting Celeste on non-Windows
systems. Keep the existing readiness check using the marker and DONE LOADING log
condition unchanged.
- Line 333: Update the relaunch failure handling around launch_game so it logs
the failure but does not continue past the aggregation block. Allow the existing
missing-results handling to record the current SID as blocked in results.json
and summary.json.
In `@Source/Packs/akron-snapshot-bundle.cs`:
- Line 196: Update the pack processing around Read and Write to enforce a
cumulative expanded-document limit: track the aggregate declared document length
using checked arithmetic, reject the bundle before invoking readDocument when it
exceeds MaxPackDocumentBytes, and apply the same aggregate bound while writing.
Preserve the existing per-document MaxDocumentBytes validation.
In `@tests/startpos-reconstruction-tests.cs`:
- Around line 3169-3170: Replace the new direct Celeste/Monocle accessor usage
throughout the affected test paths with the existing backing-field helpers,
including Components, Scene, Entity, Camera, and List capacity reads. Add a
helper for VirtualMap grid reads that accesses its backing storage instead of
the indexer, then route all relevant callers through it while preserving current
behavior and assertion outcomes.

Decode quoted arguments losslessly, reject malformed command files before dispatch, and migrate room, setup-path, TAS-path, and perf-label producers. Serialize warp acknowledgements so escaped room names survive output framing.

StartPos was refusing valid modded-room snapshots when a clean room had different object populations or when callbacks reached detached components before their owning fields. Deep graphs could overflow the save worker's stack, and boxed native pointers could leave restart copies pending indefinitely.
This reconstructs state through entity identity and authenticated ownership rather than map-specific exceptions. It preserves scene-resource aliases, retained map metadata, readonly fields, and room-owned dust styles, and stops resource indexing at process/native boundaries. Unsupported native Lua state now refuses capture explicitly instead of copying VM handles or hanging. The sweep checks actual asynchronous capture, load, and export completion.
The first commit preserves the tested setup-v10 prerequisite: shared lossless snapshot bundles, background compression, and atomic export replacement. The second contains the ownership and persistence fixes. Review follow-up bounds aggregate expansion and parsing work, fixes bulk recovery and partial-side reporting, preserves escaped automation arguments, and makes the identity index and fixtures work with CI's stripped references. Published beta 79/80 history and the merged test-audit documents are preserved.
Verification
a-0/a-2and Forsaken City1/6bpassed capture, restart-copy completion, export/import, independent cold loads, repeated warm loads, player/session comparisons, and resumed gameplay on the final ownership candidate. Screenshots showed normal gameplay.Double Vision/Feedback Loopand frozenflygoneLab-secretpassed on the preceding native-boundary candidate.Deltarefused capture with the Lua warning, left no slot or pending copy, and resumed gameplay. This verifies safe refusal; native Lua rewind remains unsupported.bash -n.Recorded hashes, timings, regression scenarios, and limitations are in the verification record.
Compatibility
Local snapshots move to
akron-reconstruction-v11; setup packs useakron-setup-v10. Recapture older StartPos slots, then re-export their packs. Positions, spawn settings, and keybinds are unchanged.File-backed automation now uses JSON-escaped quoted arguments and JSON room-warp acknowledgements. Use the updated harness with the updated Akron build. Bare arguments keep literal backslashes; the verification and perf shell harnesses require local
python3for encoding.
