reorient

name	reorient
description	Manual re-pin of the session intent anchor. Use when the developer explicitly runs /reorient, says the original goal no longer applies, or pivots the session to a fundamentally different task. Do not use for constraint refinements (the intent-anchor UserPromptSubmit hook handles those automatically) or for per-turn alignment (that is drift-aligner).

reorient

Manual override of the anchored session intent. Writes a fresh anchor.json, archives the previous one, and resets the reservoir so the new intent gets a clean drift track.

Preconditions

• A prior anchor exists at plugins/intent-anchor/state/anchor.json (else there is nothing to override).

Inputs

• new_intent: The new goal statement from the developer. Required; no default.

Steps

1. Archive the old anchor. Move the current anchor.json to state/archive/anchor-<timestamp>.json.
2. Compute alignment delta. Run engines.c1_lcs.preservation_ratio between the old and new anchor texts. Report the drop — the developer should see how far the pivot is.
3. Write new anchor. Use shared.scripts.anchor.capture_anchor with the new text, atomic write.
4. Reset reservoir. Archive plugins/drift-aligner/state/reservoir.json and start fresh — the new intent gets its own N.
5. Publish djinn.intent.captured. Fresh session anchor; downstream consumers treat this as a new-session event.
6. Success criterion: New anchor is written, old is archived, reservoir reset. Return the alignment delta to the developer.

Outputs

• Fresh plugins/intent-anchor/state/anchor.json.
• Archived old anchor under state/archive/.
• Stdout: {old_hash, new_hash, alignment_delta} for the developer.

Tier justification

This is a judgment call — the developer is pivoting, and the orchestrator has to decide whether the new intent is distinct enough to warrant a reset or is really just a constraint refresh. Opus tier per ../../../CLAUDE.md § Agent tiers.

Failure modes

• F04 Task drift. The developer may request a "reorient" that is actually just a constraint addition — in that case, refuse and point at the UserPromptSubmit refresh path. Log F04 to state/precedent-log.md.
• F11 Reward hacking. Do not rewrite the anchor silently to make future drift scores look better. The old anchor must be archived verbatim.
