rdmsm4x changelog — safely resumed halted work

Resumed only conflict-safe work from the week: repaired the fleet zero-byte monitor and completed HyperFile P1 XPC peer validation in isolated worktrees, reconciled the stale portfolio catalog read-only, and preserved every newer/dirty/actively owned canonical state.

Scope

• Host: rdmsm4x.
• Canonical development estate: /Users/richh/dev.
• Project modes: fleetreg zero-byte tripwire is Production; HyperFile is Prototype.
• No remote host was mutated.
• No branch was merged or pushed.
• No service, helper, LaunchAgent, live monitor, site, or deployment was activated.

• Canonical /Users/richh/dev/apps/hyperFile remained clean at 9a6490008de329427f6a335840a7e0d44ae59b96.

Shared index and audit output

• The existing _nocontext shared-index owner integrated exactly two bounded changes in /Users/richh/Library/Mobile Documents/com~apple~CloudDocs/Codex/projects/AGENTS.md principles/PROJECTS.md:
  • added the Fleet zero-byte tripwire milestone;
  • replaced the stale HyperFile line with the verified isolated P1 milestone.
• Shared-index SHA-256 changed from 521ae28d76ea585c29e1c26c5ff67aa9d83d893cadf718e5902c7ee4c50ea23c to 91b2060c7b34aa160a7d95365c7b014a226f3e5cc43a229abdecae5c7d5005dc; line count changed from 63 to 64. All unrelated lines were preserved.
• Created user-facing report /Users/richh/Documents/Codex/2026-08-28/resume/outputs/resumed-work-audit-2026-08-28.md, SHA-256 9eb8558d357b4748720a0d181a029d700a20d4a2b5c19b424a6f499107090a99.

Continuation and portfolio audit

• Codex task audit artifact SHA-256: f156a9bd82bf10d0bb926c6bae4d9c38bf6fe10de576b8fb38efbbe3eac701df.
• Portfolio live reconciliation artifact SHA-256: 3e3a21a9e28c6fe2769c81ad0e9055b6c67cd911361c50ae264f4e6a4729df04.
• The portfolio task performed read-only reconciliation only; no catalog, packet, source, task, folder, or archive mutation occurred.

Backups and rollback

• The feature work is recoverably preserved in named branches and isolated worktrees. The exact rollback/reference commits are fleetreg d51abdc76bcdddbd195103776f75dfb6f1e5568c and HyperFile 9a6490008de329427f6a335840a7e0d44ae59b96.
• No live runtime file was overwritten, so no live-script or LaunchAgent rollback backup was needed in this phase.
• No separate prewrite backup of the shared PROJECTS.md was created by its index owner; its narrow update is bounded by exact before/after hashes and iCloud version history.
• Do not delete either worktree or branch. If Rich later asks to discard one, enumerate its commits and require the explicit destructive confirmation defined by the branch-finishing workflow.
• If either branch is merged locally, rerun its entire acceptance suite on the merged tree before cleanup.
• A future zero-byte monitor live activation must first create an explicit timestamped backup of the current live script, LaunchAgent plist, state.json, and HALTED marker, then verify installed hashes and observed run state before declaring runtime acceptance.

Outstanding owner decisions

• Fleet zero-byte branch: merge locally, push/create a PR, or keep isolated.
• HyperFile branch: merge locally, push/create a PR, or keep isolated.
• Fleet monitor live rollout is a separate decision after source integration; the current manual HALTED gate remains active.
• HyperFile signing, helper installation/registration, and live-XPC validation remain separately gated.
• XEntropy install continuation, ReplicantDB UI continuation, Apple Shortcuts repair, Buzz, ScanRoo historical lanes, and unresolved portfolio placements remain stopped for the owner/current-state reasons recorded in the audit.
