Its planner only saw + harness state, not the task trajectory. Its parsed Update/Delete edits had no + baseline. `rollback_id` was written to JSONL but did not invert any edit. +- This change closes a deliberately narrower loop than Prime's broad trajectory + review: explicitly selected evidence -> local candidate memories -> durable + undo -> conflict-checked rollback. It is not a claim of feature parity, a + general learning system, or a measured performance improvement. + +## Native API and authorization + +`session/refine/run` accepts an optional `trajectoryItemIds` array. Omitting it +preserves the existing instruction/consolidation behavior. With selected evidence, +the planner uses a fixed, constrained distillation directive rather than arbitrary +`instructions`. For example: + +```json +{ + "sessionId": "", + "trajectoryItemIds": [""] +} +``` + +Trajectory selection requires an idle root session. Sanitized evidence is frozen +in memory at admission, so a later turn cannot expand the selected text. + +A client must show the selected text for the user's review before submitting IDs, +and explain that the session's configured model/provider will receive that text +and the current target harness entries. This API field is the explicit selection +boundary, not an automatic history-mining permission. There is no new UI picker +in this change; clients may obtain IDs through the existing session item API. + +- At most 16 IDs from this root session, at most 2,000 Unicode characters per + item and 12,000 in total. Duplicate/missing IDs and unsupported types fail + closed. Selection is read from the session actor, not arbitrary paths/journals. +- User text, assistant text and string-valued ToolResult outputs are supported. + Reasoning, images, arbitrary structured tool output, arguments, provider + payloads, file paths and child transcripts are not traversed or serialized. +- Trajectory selection cannot be combined with global scope, rollback, automatic + refinement or a child session. Python/kernel `refine.run` rejects trajectory + selection; an agent cannot opt itself into reading additional history. +- Known secret markers cause the whole matching line to be replaced before the + model call. This is **best-effort** redaction, not a comprehensive secret/PII + detector. User review remains necessary; do not select sensitive text merely + because this filter exists. Text may also be truncated, explicitly marked. +- Excerpts are JSON data labelled untrusted, including historical user-role text. + They do not authorize new instructions, permissions, preferences or policies. + The host permits at most four local memory Create edits, with bounded text and + no file path. Prompt/skill/subagent edits and Update/Delete are rejected. +- Candidate memories retain source item IDs and an `unverified_trajectory_lesson` + trust label. Their digest explicitly warns that they are unverified suggestions, + not instructions or permissions. Ordinary consolidation does not receive + candidate entries, preventing that path from silently reclassifying them as + skills/prompts. This is defense in depth, not a proof that + prompt injection or hallucination is solved. Raw selected excerpts are not + copied into a separate durable trajectory archive. +- Empty model edits remain a no-op. Invalid/failed trajectory planning does not + fall back to copying the request into memory. Apply failures are persisted as + `refinement_not_applied` warning items, not successful refinement items. + +All manual and automatic refinement/rollback writes defer in Plan Mode. The +planner holds no store lock; host-owned baselines are captured before its model +call. Entries become available at the existing next-turn digest boundary. + +## Atomic persistence and real rollback + +The existing cross-process sidecar lock covers one read/check/write transaction. +`harness_state.json` now holds optional `refinement_history`, containing the +actual committed before/after images and rollback links. Entries, normal history +and undo records are serialized into one private temporary file, synced and +atomically replaced together. A later invalid edit leaves the whole previous +file unchanged. CRUD keeps this additional field intact. + +New `refinements.jsonl` files are private and append-locked; existing file +permissions are preserved. The file is a compatibility audit mirror. +It is not the rollback authority. A mirror append failure cannot lose the +canonical undo record or turn a partial write into a valid history entry. + +To undo an entry, send the existing Native fields: + +```json +{ + "sessionId": "", + "rollbackId": "", + "global": false +} +``` + +Rollback bypasses the model, constructs inverse Create/Update/Delete operations +from committed history, and verifies every affected current entry against the +recorded post-image before committing. Unrelated entries survive. Update versions +increase, including on undo, so restoring equal content does not erase the +history conflict. Duplicate rollback, missing/legacy-only history, stale edits, +identity mismatches, duplicate entry edits and immutable base-prompt edits fail +without partial application. Global rollback requires explicitly selecting the +global store; stored paths never redirect a write. + +Old state files load with empty undo history. Old JSONL records are intentionally +not guessed into reversible changes, because they may lack baselines or may +have been appended independently of a successful state commit. An old binary +that rewrites state can drop the new optional history field; downgrade therefore +loses rollback availability, not silently reconstructs it. History is not pruned +in this minimum implementation and retains prior entry content for undo. A +privacy purge/retention UI and bounded archival need a separate design. + +## Regression and evaluation boundaries + +Coverage includes Create/Update/Delete undo after reload, stale forward/undo +conflicts, all-or-nothing validation, legacy-only history refusal, simultaneous +rollback, unrelated concurrent edits, monotonic versions, private files, +unsupported/duplicate/missing trajectory selection, Unicode bounds, known-secret +redaction, structural trust restrictions, digest-marker escaping, manual Plan Mode and audit-mirror +failure.
