rdmpw3275m-changelog-20260914-1755-tyrell-build23-r1-short-gate-pass

Build 23 R1 passed the unchanged short physical-footprint gate on the designated canary; long-runtime, repeated-inventory, controlled-reboot, integration, and rollout acceptance remain pending.

Scope and changes

• Coordinator/control host: rdmpw3275m; canonical records: rdmsm4x; runtime checks and fresh app probe: designated canary rdmbair15m5 only.
• No fleet expansion, source integration, merge, tag, release, Build 22 install, or Build 20/21 relaunch occurred.
• Added canonical short-gate evidence at /Users/richh/dev/_handoff/tyrell-build23-memory-20260914/canary-r1-short-gate-20260914-1741.
• Added a reproducible gate comment to ISSUE-20260912-01 and extended the coordinator lease through 2026-09-15 01:51:42 EDT.
• Updated only the Tyrell row in canonical /Users/richh/dev/PROJECTS.md; after SHA-256 1d953ba49c996dc37102268a0d85b825ce8ab1c16456638dbe96761284605fce.
• Updated the owned fleet check-in to build23_r1_short_gate_passed_long_gates_pending.

Commands and verification

• Independently imported the frozen staged memory_gate.validate_window, selected the first 31 samples at or after 600 seconds, and compared the result structurally with short-gate.json.
• Exact match, RC 0: 31 samples / 1800.305619955 seconds; physical endpoint 106.048133850 MiB; endpoint growth -2.079856723 MiB/min; least-squares growth -0.234698030 MiB/min. Limits remain 300 MiB and +0.20 MiB/min.
• One exact PID 26620/start/path; max gap 60.044849873 seconds; descriptor endpoints 26->26/range 26..27; TCP exactly 2; every status and permission probe HTTP 200 valid JSON; all gate samples rdmbair15m5/AC/open.

Rollback and remaining gates

• Guard still retains exact signed Build 15 daemon SHA-256 dbc440bd54b85a54dd6c4150b23b3e508bff7d8d8080687d81b9ba7ac2cbbcf0 and Build 17 app SHA-256 8693ebce3d474fed049597d11e3579bf1cd32f7a78acfd9544c78d77592da05e.
• Fresh backup remains /Users/richh/Library/Application Support/Tyrell/backups/20260914-1656-build23-r1-preflight-093d653/tyrell.db, SHA-256 94cd2cf7b743f54a75235d49e6ff3d8095866a4a179252c906fb1fce40d6833d; do not restore over a healthy live DB.
• Keep rdmbair15m5 on AC with lid open. Do not reboot, sleep, relaunch, accept, or expand the candidate.
• Six-hour gate cannot run before 2026-09-14 23:11:47 EDT; fixed 24-hour gate before 2026-09-15 17:01:47 EDT.
• Only one inventory pass is complete and unchanged_repeat=false; repeated-inventory, CPU, later fresh-app, controlled-reboot, integration, and fleet-rollout gates remain open.
• Build 22 remains READY_QUEUED_NOT_INSTALLED; its daemon is prohibited. Separate bug ISSUE-20260914-15 must not be integrated into this frozen candidate.
