Revalidated unchanged ecs0lib adoption and ownership boundaries, independently reproduced a false-success Cascade Lake Homebrew sweep, and routed canary and divergent-repository lifecycle gates without changing product source or stopping live work.

Scope

• Execution host: rdmsm4x, local time 2026-09-02 00:20-00:27 EDT.
• Fleet reachability: message-bus sync succeeded to rdmbair13m5, rdmbair15m5, rdmpw3265m, rdmpw3275m, and jdmbair13m5.
• Canonical read-only inspection: /Users/richh/dev/lib/ecs0lib, /Users/richh/dev/lib/ECSCloudKit, 52 filtered immediate roots under /Users/richh/dev/apps, /Users/richh/dev/fleet/homebrew-intel, and the ticket store.
• Remote read-only inspection: active Homebrew build and logs on rdmpw3275m; process, memory, and swap state on rdmbair15m5.
• No application/library source, runtime, signature, deployment, published service, credentials, or user-owned process was modified.

Local state changed

• Updated /Users/richh/.agent-coordination/checkins/codex-rdmsm4x-ecs0lib-portfolio-monitor-20260901.json; it parses with jq -e and now hashes to 9dbe83bfa7cbab7d9d3f817c7c328687e1dd3d9163ccc71623ff8b055e3fa6c7.
• Appended one evidence comment to the already claimed TASK-20260830-02; its existing monitor lease remains valid through 01:41 EDT.
• Sent two immutable fleet-bus messages:
  • 20260902-002355-3D43C434 to claude@rdmsm4x and claude@rdmpw3275m: independent reproduction of ISSUE-20260902-01 and an offer to verify a corrected artifact only after an exact ticket/path/commit handoff.
  • 20260902-002531-C408DA0A to claude@rdmsm4x: current Tyrell canary health gate plus replicantDB/rooDB integration-state boundaries.
• Added this Markdown changelog. It will be mirrored into the iCloud llmlog Apple Notes folder and read back before completion is reported.

Shared-library state

• ecs0lib remains at 90c3c6ddd6377be6012617d1934a5fbce5c028aa with the same 14 ownerless untracked Swift files under Sources/ECS0System/Hardware, Sources/ECS0System/Provenance, and Tests/ECS0LibTests.
• All 14 current SHA-256 values exactly match the 23:44 manifest in the monitor check-in. No owner/ticket response arrived for them.
• ECSCloudKit remains clean at 93b9f700e7b73c02881b0a00007cb6f813720a43.
• Recomputed over 52 immediate canonical app roots, excluding dist, _review-shared, hidden agent/worktree/review roots, and the duplicate Xentropy reconciliation root:
  • ecs0lib: 26 declarations / 22 production-source importers.
  • ECSCloudKit: 15 declarations / 1 production-source importer.
  • ProcessRunner: zero active local declarations; only the two explicitly archived superseded copies in AINetNode and updateRoo were found.
• No shared-library file was staged, built, tested, or released for consumer adoption.

Independently reproduced Homebrew false-success defect

• New high-severity ISSUE-20260902-01 records that an active script advertised as Cascade Lake recompilation actually produces Homebrew's Westmere baseline and then labels the non-bottle receipt as native.
• On rdmpw3275m, /Users/richh/dev/scripts/brew_recompile_cascadelake.zsh is 636 lines and SHA-256 53fe1d038a70d649bd4b9e0e4fa85b1780e9540602bd86a7048a7e8072060834.
• Direct source inspection reproduced:
  • lines 538-540 export HOMEBREW_OPTFLAGS, HOMEBREW_ARCH, and HOMEBREW_OPTIMIZATION_LEVEL for Cascade Lake;
  • line 602 runs brew reinstall --build-from-source;
  • line 377 labels poured_from_bottle=false as Locally Compiled (Native).
• Installed Homebrew source independently shows super.rb:95 assigning HOMEBREW_OPTFLAGS = determine_optflags; super.rb:322-326 obtains the architecture from effective_arch; and shared.rb:298-302 selects Hardware.oldest_cpu in this path.
• Empirical build logs reproduced the reporter's exact counts:
  • blake3: 24 occurrences of -march=westmere, 0 of -march=cascadelake.
  • aribb24: 126 occurrences of -march=westmere, 0 of -march=cascadelake.
• The interactive sweep remained live as pid 34720 with boost child pid 90251 and b2 pid 91966 at 100 percent CPU. This monitor did not signal or stop it.
• fastfetch remained absent after the failed tuned-bottle attempt. The expected tuned-bottles directory remained absent, so bottle delivery count remains 0.
• claude@rdmpw3275m validly reclaimed FEAT-20260901-45 at 00:03 through approximately 04:03. The ticket note's proposed openssl-first build is not delivery evidence; no bottle exists yet.

App, ticket, and integration deltas

• replicantDB canonical main advanced to 190f8953660c535000e2386bd65f86bc872ff650 for resolved SEC-20260901-06. The owner reports 1,105 tests with no failures. Current lifecycle truth is local-only and divergent: main is ahead 1 and behind 2 relative to both fleet/main and backup/main at 736c5d8, with seven dirty/untracked entries. It is not accepted as integrated or published.
• rooDB canonical main advanced to 963707f228b246f2e729ea6840f842ecdd94852e, also for SEC-20260901-06. The owner reports 172 tests with no failures. Current main is one commit ahead of fleet/main, backup/main, and origin/main at b462f0e; Support/ remains untracked. It is a valid local commit, not remote publication evidence.
• Tyrell canonical main advanced to b423a6dda41408dea091d3fe1cd639c3a70a5ed9 with 18 dirty/untracked entries. New TASK-20260902-01 is claimed by claude@rdmsm4x through 06:20 for a canary-to-fleet 0.2.0 build 4 deployment. This monitor will not sign or deploy.
• New FEAT-20260901-48 covers promoting discovered labels into the rooDB/replicantDB runtime vocabulary.
• No new immediate app or library directory was created. fleet/audit and fleet/overnight are older roots with new periodic reports, not new projects.
• Open governance observed: EPIC-20260831-02, SEC-20260830-01, REV-20260901-01, ISSUE-20260901-24, ISSUE-20260901-26, ISSUE-20260901-27, TASK-20260901-08, and ISSUE-20260902-01.

Tyrell canary and live-host gate

• New TASK-20260902-01 requires rdmbair15m5 as the mandatory Tyrell canary.
• Direct measurement there at 00:25 EDT still reproduced ISSUE-20260901-26:
  • replicantDB.app pid 1588: 11 GB memory and 11 GB compressed memory.
  • swap: 23,644.62 MB used of 24,576 MB.
  • physical memory: 962 MB unused.
  • both duplicate instances of Claude session 8d3fab16-38d4-4ccb-a35c-23644fe23a4e, pids 2624 and 70386, remain live.
• The earlier host owner paused further builds and killed nothing. The monitor asked the Tyrell lead to record a current canary health gate or explicit risk acceptance before deployment. It did not replace the canary, signal a process, or choose a session survivor.

Commands and verification

• scutil --get ComputerName, date, agent_msg.zsh whoami, agent_msg.zsh sync, focused bus reads, and recent-message enumeration.
• Read-only git rev-parse, git status --short, git log, git show --stat, branch/ref comparison, file enumeration, and per-file SHA-256 reconciliation.
• A manifest-aware app scan over source-of-truth package/project files and production Swift imports, with build, test, archive, support, snapshot, hidden, scratch, and review paths excluded.
• ticket show, ticket list, ticket search, and ticket claims --all for the named monitor/governance/new tickets.
• Remote read-only ps, pgrep, top, sysctl vm.swapusage, source rg, and Homebrew log flag counts.
• The first hash-comparison shell expression failed due quoting in its awk/jq fragments and therefore supplied no evidence. It was immediately replaced by a non-pipeline zsh loop; that valid run returned HASH_MISMATCHES=0 with exit 0.
• The first remote process query also failed before execution because an unquoted zsh pattern expanded locally. It was replaced with a safely quoted SSH command; all runtime evidence above comes only from the successful direct queries.

Backups, undo, and owner actions

• No product source or runtime was changed, so there is no source rollback action from this monitor.
• The 14 ecs0lib files remain in place and retain their prior hashes. Their full hash manifest is in the check-in. Do not reset, clean, stage, or adopt them until an owner/ticket is named.
• Ticket comments and fleet-bus messages are append-only evidence. Correct them by appending; do not delete them.
• To undo only the mutable monitor metadata, restore the prior check-in from coordination-integrity history if available and append a correction to TASK-20260830-02. Do not use that as authority to change any product worktree.
• Homebrew sweep owner: decide whether and how to stop or drain pid 34720, restore fastfetch, and use an architecture-valid bottle workflow. This monitor deliberately did not choose for the interactive job owner.
• Canonical leads: hand off ISSUE-20260902-01 or a child with exact corrected paths/commit and expected negative-control plus bottle-architecture evidence if independent verification is wanted.
• Tyrell lead: gate rdmbair15m5 canary use on current health evidence or record explicit risk acceptance; keep deployment lifecycle separate from successful local build state.
• replicantDB/rooDB owners: reconcile divergent/remote histories and dirty files before claiming integration or publication.
• Canonical ecs0lib lead: identify the owner/ticket for the 14 untracked files before any consumer migration.
