FE-1316: Audit current system authority and drift

[lunelson]

Why

After a run of related work landed, this was a scheduled check-in: are we tracking every open thread correctly, and has anything drifted out of sync between what the docs say and what the code actually does? This is a review pass, not new product functionality.

What

• Reviewed 13 areas touched by recent work for leftover dead behavior, doc/code drift, and follow-up work that had lost its owner.
• Found and fixed one real, if small, product issue: outdated on-screen guidance text shown during a review step that no longer matched how corrections actually work.
• Confirmed the surrounding executor, comparison, and tracing subsystems are each on track with their existing owners rather than silently stalled.
• Opened two focused, scoped follow-ups instead of leaving loose ends: reconciling drifted internal documentation, and closing a gap in how we fingerprint automated test evidence (see the two PRs stacked above this one).

How to test

This is an audit/planning pass with one small text fix.

1. npm run check passes.
2. The two admitted follow-on issues (FE-1317, FE-1318) exist in Linear and are addressed by the PRs stacked on top of this one.

PR Summary

Low Risk
Planning-archive updates plus prompt-guidance text and tests; no executor or capture logic changes in this diff.

Overview
FE-1316 system reorientation audit is recorded as complete in memory/PLAN.md and docs/archive/PLAN_HISTORY.md: thirteen post-cleanup concerns get evidence-backed dispositions, promoted work stays with existing owners, and the temporary audit ledger is removed. Two Next frontiers are added—canonical-document-reconciliation (normative doc drift from the inventory) and host-landing-oracle-identity (PTY inputs in the host-landing oracle pack hash)—with full frontier definitions and dependency-graph entries.

The only runtime change fixes stale present_digest prompt text that still told providers to use approve / request changes / reject on the continuation ask. Guidance now matches the landed flow: continued asks collect conversational free-text corrections, do not accept the digest for capture, and require a successor digest plus a separate ask with acceptsDigest to authorize capture. exchanges-extension.test.ts asserts the new strings and explicitly rejects the old tri-state wording.

Pull request overview

This PR performs a documentation/audit pass following FE-1316, tightening the structured-exchange “present_digest → ask” guidance to match the current conversational correction flow, and updating planning artifacts to record the audit closeout plus two newly admitted follow-on frontiers.

Changes:

• Updated present_digest tool description/guidelines to reflect free-text correction continuations and the separate acceptsDigest capture step.
• Adjusted extension tests to assert the new guidance and reject the deprecated approve/request-changes/reject phrasing.
• Recorded FE-1316 closeout and admitted frontiers in memory/PLAN.md, with corresponding archival notes in docs/archive/PLAN_HISTORY.md.
