+## Phase 22: Conductor-loop calibration with a live collaborator (#43)
+
+- First full loop through the live-seat path: decompose → dispatch
+  (agent-send.sh, class=actionable) → receipt → line-by-line diff review →
+  suite-gated integration. Worker: ms-test seat (glm-5.3-flash) in the repo
+  cwd, scoped to docs/TOOLS.md, no git.
+- Before (conductor baseline): suites 24/74/14/17 green; TOOLS.md had no
+  tools/ coverage; Maintenance table claimed test-task.sh = 58 cases (stale).
+- After: TOOLS.md gains "Tools (host-side)" (agent-send.sh, agent-watch.sh,
+  unslop-check.js), corrected counts, reading-guide fix; suites 24/74/14/17
+  + verify green post-integration.
+- Masking-failure rule applied: every documented flag/subcommand/exit code
+  independently verified against tool source by the conductor, not taken
+  from the worker's report (all claims checked out).
+- Worker caught a spec gap the conductor missed: the intro reading-guide
+  ("all entry points are scripts/*.sh") became false with the new section;
+  amendment flagged, reviewed, accepted.
+- Process correction: the worker's first reply was typed into the pane
+  without agent-send.sh and never delivered; the protocol resend is the
+  report of record. Comms discipline is load-bearing, not ceremony.
+- CURRENT.md staleness corrected: it still named M16 as next though M16
+  (#38) and M17 (#40–#42, skill-lifecycle-v1, release 0.0.12) had shipped;
+  late entries added to its completed log, next action is now M18.
+
+## Result (calibration)
+
+The conductor loop is proven end to end on a live seat; TOOLS.md covers the
+tools/ tree; suites green at every gate.
