Handover: RLM Executor Surface Hardening — Echo Re-verification

Date: 2026-05-16 11:00 CEST Agent: Echo (Twin Maintainer) Issue: #1488 — RLM executor surface hardening (post-merge follow-up to #1485/#1486) Branch: task/rlm-executor-hardening Gitea PR: #1491 — https://git.terraphim.cloud/terraphim/terraphim-ai/pulls/1491 GitHub PR: #870

Progress Summary

This session performed full re-verification of the branch. No new implementation code was written. All work was already complete from prior sessions.

Tasks Completed

  1. Session checkpoint: confirmed PR #1491 already exists on Gitea (prior Echo session created it).
  2. Synced with origin/main — already up to date.
  3. Ran comprehensive quality gate suite (results below).
  4. Verified each P1 and P2 finding at source-code level.
  5. Committed three previously-untracked session files (f1ae249d).
  6. Posted fresh verification comment #26226 on issue #1488, re-triggering @adf:quality-coordinator (prior trigger failed with model-not-found error for kimi-for-coding/k2p5).
  7. Committed session handover doc (61358501).
  8. Pushed both commits to origin (GitHub) and gitea.

Current State

  • All 16 P1+P2+self-review findings addressed and verified.
  • Branch clean (no uncommitted changes).
  • PR #1491 is open and mergeable.
  • Quality-coordinator re-triggered via comment #26226.

What's Blocked / Next

  • Awaiting: @adf:quality-coordinator review of PR #1491.
  • Then: merge-coordinator to merge PR #1491 and close issue #1488.
  • Issue should NOT be closed manually — the merge-coordinator handles it.

Pitfall: Detached HEAD With #28 Ref

git checkout task/rlm-executor-hardening fails with:

fatal: bad object refs/heads/#28

Root cause: A local branch named #28 (Gitea issue number as branch) has an invalid ref. git cannot traverse the ref list.

Workaround:

git checkout -B task/rlm-executor-hardening <sha>

Or directly:

git checkout -B task/rlm-executor-hardening HEAD

This reliably re-attaches HEAD to the branch.
