rdmbair15m5-changelog-20260914-1827-tyrell-build23-r1-repeat-inventory-pass

Build 23 R1 completed a second matching inventory pass on rdmbair15m5, satisfying only the unchanged repeated-inventory prerequisite while the protected canary continues soaking.

Scope and changes

• Host: designated Tyrell canary rdmbair15m5.
• The existing guard automatically recorded pass 2 at 2026-09-14 18:09:14.868 EDT; no operator changed the canary runtime, daemon, app, database, guard, launchd configuration, or power policy.
• Documentation evidence was captured from the live state and promoted to /Users/richh/dev/_handoff/tyrell-build23-memory-20260914/canary-r1-repeat-inventory-20260914-1809.
• This changelog is the only newly staged file on the canary host. No reboot, sleep, relaunch, acceptance, fleet expansion, Build 22 installation, merge, tag, or release occurred.

Verification evidence

• Pass 1 and pass 2 each covered 38 roots across 29 bundle plans. The guard's name-size-mtime comparison set completed_passes=[1,2] and unchanged_repeat=true.
• The transition sample retained daemon PID 26620, start Mon Sep 14 17:01:46 2026, the exact hash-addressed Build 23 path, 50,611,424 physical bytes, 26 descriptors, TCP count 2, and the required AC/open envelope.
• Read-only guard/power/interlock verification passed with guard PID 26393 and caffeinate PID 26474. Both sleep assertions remain active; candidate autoload remains disabled and the persistent recovery sentinel remains loaded and armed.
• The live canary verifier returned RC 0. The immutable snapshot contains 81 samples spanning 4800.827883005 seconds with maximum gap 60.044849873 seconds, one PID/start/path, descriptor range 26..31, TCP count 2, and all status, permission, and power-envelope checks valid.
• Snapshot MANIFEST.sha256 verifies all 96 entries with RC 0; manifest-file SHA-256 is 1885c7230392ca9ab02052327862a245a2ede0e9d2ecd688f354da3c56e15097.

Recovery and remaining gates

• Exact signed Build 15 daemon SHA-256 dbc440bd54b85a54dd6c4150b23b3e508bff7d8d8080687d81b9ba7ac2cbbcf0 and Build 17 app SHA-256 8693ebce3d474fed049597d11e3579bf1cd32f7a78acfd9544c78d77592da05e remain the rollback pair. The healthy live database must not be overwritten.
• No runtime undo is applicable because this milestone performed read-only verification and documentation. Removing the documentation would not alter the active canary and is not required.
• Six-hour gate remains no earlier than 2026-09-14 23:11:47 EDT; fixed 24-hour gate remains no earlier than 2026-09-15 17:01:47 EDT. CPU, later fresh-app, controlled-reboot, integration, and rollback-protected rollout gates remain open.

Outstanding owner action: none; keep the host on AC with its lid open while the unchanged guard continues.
