Recorded the clean Tyrell Build 16 and ReplicantDB memory-bound source checkpoints that landed after the 23:24 monitor snapshot, completed two explicitly pending Tyrell Apple Notes records from an Aqua session, and preserved all release/runtime gates.

Scope and relationship to the primary record

• Host: rdmsm4x; observation and assist window 2026-09-02 23:27-23:33 EDT.
• This addendum supplements /Users/richh/dev/LLM/Claude/changelogs/rdmsm4x-changelog-20260902-2324-ecs0lib-post-reboot-portfolio-monitor.md without rewriting its accurate earlier snapshot.
• Monitor ticket: TASK-20260830-02, owned as metadata-only by codex@rdmsm4x/ecs0lib-monitor through 2026-09-03 01:24:54 EDT.
• No application/shared-library source, owner worktree, foreign ticket lifecycle, installed runtime, process, signing identity, device, database, service, canary, deployment, publication, credential, or destructive state was changed by this monitor.

Tyrell Build 16 checkpoint

• The resumed isolated owner committed source correction a991b308e492d5001dd235e1e11724089651ee52 and clean documentation head 117b4a89ef7b9fbe62f857c18bb03fd465b2d0d5 in /Users/richh/dev/_worktrees/tyrell-build16-ios-lifecycle-20260902.
• FEAT-20260902-33 is resolved within the source-only boundary. SEC-20260902-04 remains in progress for independent rereview of the corrected range; no integration acceptance is inferred.
• The monitor checked the retained evidence files and reproduced their SHA-256 values:
  • Focused iOS log: 1f969c264a38fe242b0abf4859735760049ae8d71db6cd67370faaa5d177aeb8; visible aggregate 21/21, zero failures. The owner records 2,000/2,000 configuration-boundary iterations.
  • Fresh iOS full log: 03536b9cb3dea64d509d60b0e19b5fc86aa3f1fbc216dfccc13b216daed8c33c; visible aggregate 72/72, zero failures.
  • Package log: 1f6cd6adf73f2968bc51a97e554e8dcc437dc00dc3171fdf5250934ef1131f83; 242 XCTest plus 404 Swift Testing equals 646/646, zero failures.
  • Unsigned iOS Release, TyrellCloudProjection Release, and tyrell-app Release logs have SHA-256 0775cffc58729cb56d9b7cd9ed0e23c1fb746070f736546aa579f8efecdab8ca, 9f5c4233f1ee9026994bf9a8b950b5939ce8b80ffd106a3766ca21039685053b, and d940582f0b913818c42fbf35e857d7973be98e600d0233adc6ee4dd8475722fa.
• The clean source candidate is not signed, integrated, installed, canaried, or deployed. Build 11 remains the accepted live fleet runtime.

ReplicantDB bounded-memory checkpoint and hold

• The isolated worktree /Users/richh/dev/_handoff/codex-out/replicantdb-memory-bounds-20260902 is clean at documentation head 6bab2f1, over source commit 259c791 and base 0310483.
• Source changes replace passive full duplicate-detail hydration with SQL aggregate counters and a bounded/lazy browser while preserving explicit all-groups dedup semantics.
• Owner evidence records focused DuplicateStatisticsMemoryBoundTests at 4/4.
• The full package suite reached 1,095 executed with one failure. The failure is not accepted as a passing release gate: LocalIntelligenceTests launches nested swift package describe while the outer swift test holds the same worktree .build lock. The owner sampled the wait, attributed parent/child lock ownership, terminated the blocked child, and filed blocking ISSUE-20260902-20.
• ISSUE-20260901-26 remains in progress and explicitly HOLD before build, signing, process restart, database operation, canary, or deployment. The earlier installed runtime was not changed.

Intel update progress

• rdmpw3275m advanced from 168/206 to 172/206 at 23:26 EDT through the existing private pinned run.
• mackup recorded nocompile; mas was building. No skip, stop, restart, rerun, or configuration change was made.
• rdmpw3265m remains complete at its previously recorded warning outcome.

Apple Notes durability assist

• Two owner check-ins explicitly recorded that their background Codex sessions could not send AppleEvents and preserved exact local changelog files for the next Aqua-capable session.
• This monitor verified launchctl managername=Aqua, then submitted:
  • /Users/richh/dev/LLM/Claude/changelogs/rdmsm4x-changelog-20260902-2327-tyrell-build16-ios-lifecycle-correction.md, SHA-256 a6c18b85738435c3624f0b66df297885d63e3cef5de051bbcc0161d62be8391c, attributed to FEAT-20260902-33.
  • /Users/richh/dev/LLM/Claude/changelogs/rdmsm4x-changelog-20260902-2320-tyrell-build17-menubar-successor.md, SHA-256 bb1f667ef9a6b5e344cda90a2bbf0d140a6ec39d5075131cb43756d74660fb60, attributed to ISSUE-20260902-19.
• Both helper calls returned OK.
• Direct Apple Notes llmlog readback found Build 17 as the newest note, created 23:32:16 EDT with 5,676 HTML body characters, and Build 16 second, created 23:31:53 EDT with 9,844 HTML body characters.
• Message 20260902-233249-70E479A2 told the owners that publication is complete and asked them not to retry, preventing duplicate Notes entries. It also offered a bounded independent review of ISSUE-20260902-20 or the memory candidate after exact ticket/path/log transfer.

Files and metadata changed by this monitor

• /Users/richh/.agent-coordination/checkins/codex-rdmsm4x-ecs0lib-portfolio-monitor-20260901.json received the post-checkpoint addendum and remains valid JSON.
• /Users/richh/dev/issues/open/TASK-20260830-02-monitor-shared-libraries-and-repair-reus.md and /Users/richh/dev/issues/index.sqlite received one additive monitor-ticket evidence comment.
• /Users/richh/.agent-coordination/mail/20260902-233249-70E479A2__from-codex-rdmsm4x__to-codex-rdmsm4x-claude-rdmsm4x__tyrell-notes-completed-and-replicant-hold-offer.md was created by the immutable bus.
• Two Apple Notes entries were created from the already-existing Tyrell changelog files.
• This addendum file was created and is submitted through /Users/richh/scripts/notes_changelog.zsh for its own durable record.

Verification, rollback, and next actions

• Commands were read-only except for the stated monitor metadata and Notes records: git status/log/show, shasum -a 256, retained-log rg, ticket show/comment, check-in jq, Notes helper/readback, bus send/sync, and remote retained-log inspection.
• No product backup was required because no product source/runtime was changed by the monitor. The named Git commits and owner handoffs are the preservation points.
• If a Notes record is later found duplicated, keep the ticket-attributed entry and remove only the duplicate after checking its body and creation time. Do not delete either source changelog.
• Tyrell integration must wait for SEC-20260902-04 rereview and later signing/local/canary gates.
• ReplicantDB must resolve or deliberately isolate ISSUE-20260902-20, rerun an unambiguous full suite, then pass candidate build and rollback-protected canary gates before any fleet deployment or cleanup.
• Canonical ecs0lib, ECSCloudKit, and adoption counts remain unchanged from the primary record.
• No secrets, tokens, credentials, signed URLs, or private application payloads were recorded.
