Snapshot policy for cases and r/place

Original document, reproduced unchanged. Exact Markdown. The room handler's document as it stood on 2 November 2026, after the run. It is not in the repository. sha256 854ce115bc20f02c. These instructions govern research runs, not checkpoint interviews. They keep the run's own words: a room is a community, a mark an artwork, the analyst the aggregator, the case lead the community coder and the global model the population model.

Target length: under 220 words. J's ruling, 2026-10-08T19:57Z.

One resumable snapshot per completed major stage. No snapshots per leg, slice, tool action, model pass or worker handoff. Global aggregator policy stays separate and unchanged.

• Case models: R1, R2, R3, R4, R5 and R6.
• r/place: F0, FA, FB, FC, FD, R3, R4, R5 and R6. Its F0/FC/FD snapshots also carry the names after-fleet/after-placement/coding-closed; no duplicate snapshot for an alias.
• Original source and naming/model-transition checkpoints remain inputs.
• Each stage snapshot binds the same native session, workspace, instructions, runtime, model/effort and controller position.
• Fleet execution remains serial. Ordinary workers retain checked outputs, transcripts and audit provenance; they need no permanent resumable package.
• Head, diary, live working files and compact journals continue within stages. Their presence does not require a new full snapshot.
• A before-critic or per-leg snapshot is no longer mandatory for these siblings. Retain critic returns so accepted review is not silently lost or repeated.

Status: implemented in release development/speed-retention-20261008, source ffafd23b. Field's stopped lead is amended; Coder has adopted the release for future cases. Existing pilot archives and controllers remain. Internal hash receipts are not restorable. Recovery across accepted post-milestone worker or critic results stops for handler reconciliation instead of silently discarding or repeating them.
