rdmpw3275m-changelog-20260922-1148-global-app-standard-propagation

Propagated the versioned Global App Standard v1.0 block and app-baseline pointers across all 6 fleet hosts to eliminate the Gemini and Codex context gap and resolve TASK-20260830-04.

Scope

• Hosts: rdmsm4x, rdmpw3265m, rdmpw3275m, rdmbair13m5, rdmbair15m5, jdmbair13m5 (all 6 fleet hosts).
• Harnesses: Claude Code, Codex, Antigravity (agy / Gemini).

Files Modified & Backed Up

On every host:

1. ~/.claude/CLAUDE.md (backup: ~/.claude/CLAUDE.md.bak-standard-<timestamp>)
2. ~/.codex/AGENTS.md (backup: ~/.codex/AGENTS.md.bak-standard-<timestamp>)
3. ~/.gemini/GEMINI.md (backup: ~/.gemini/GEMINI.md.bak-standard-<timestamp>)
4. ~/.agent-coordination/AGENT_COORDINATION.md (backup: ~/.agent-coordination/AGENT_COORDINATION.md.bak-standard-<timestamp>)
5. ~/.agent-coordination/ACTIVE-DIRECTIVES.md (backup: ~/.agent-coordination/ACTIVE-DIRECTIVES.md.bak-standard-<timestamp>)

Fleet Ops Tooling Created

• ~/dev/fleet/ops/propagate-global-app-standard/rule.md: Definitive versioned markdown block (<!-- BEGIN global-app-standard v1.0 (2026-08-30) --> to <!-- END global-app-standard v1.0 -->).
• ~/dev/fleet/ops/propagate-global-app-standard/apply_standard.py: Idempotent local insertion script with safety backups and verification assertions.
• ~/dev/fleet/ops/propagate-global-app-standard/propagate.zsh: Multi-host runner targeting hub (rdmsm4x) first, then all 5 peers, followed by auto-promotion to rdmsm4x:~/dev/fleet/ops/propagate-global-app-standard/.

Key Invariants & Standard Content

• Canonical Baseline Pointer: Points directly to rdmsm4x:~/dev/lib/app-baseline/ (PROJECT_KICKOFF.md, PLATFORM_TARGETS.md, DESIGN_SYSTEM.md, DOCUMENTATION.md, MERGE_AND_INTEGRATION.md, THREAD_DISCIPLINE.md, OPERATING_MODEL.md, TICKETS_AND_ALARMING_DIFFS.md).
• Apple Developer Facts & Signing: Points to rdmsm4x:~/dev/lib/app-baseline/APPLE_DEVELOPER_FACTS.md as the single authoritative record. Mandates Developer ID Application signing (ZU2882L4HT), hardened runtime, --timestamp, ecs-notary notarization, and stapling via ~/dev/lib/app-baseline/scripts/ecs_sign_notarize.zsh (DEC-20260909-03).
• Platform Targets: Apple Silicon & iOS on 27.0 target / SDK; Intel (rdmpw3265m, rdmpw3275m) pinned to macOS 26.7.
• Universal2 Build Gate: lipo -archs verification mandatory (x86_64 arm64). Universal is necessary and not sufficient for Intel; 26.7 target is required.
• Bundle IDs & CloudKit: com.eastcoastscience.<Product> and iCloud.com.eastcoastscience.<Product> permanent and immutable across platforms.

Commands Executed & Verification Evidence

1. Check-in published: ~/.agent-coordination/checkins/rdmpw3275m-agy-task-20260830-04-20260922.json and synced fleet-wide via ssh rdmsm4x 'zsh /Users/richh/dev/fleet/maintenance/scripts/fleet_checkin_sync.zsh'.
2. Propagation run: zsh /Users/richh/dev/fleet/ops/propagate-global-app-standard/propagate.zsh.
   • Result: 6/6 hosts reported returncode 0 with all target files applied/verified.
   • Promoted to rdmsm4x:~/dev/fleet/ops/propagate-global-app-standard/.
3. Independent audit: Checked presence of BEGIN global-app-standard v1.0 in all 5 files on all 6 hosts via SSH.
   • Result: 30/30 PASS (100% verified).
4. Ticket resolved: ticket resolve TASK-20260830-04.
5. Bus broadcast: Message 20260922-114811-3EAC2185 broadcast to all and synced across all 5 remote nodes.

How to Undo

If rollback is ever needed on any host: Restore from backup files created during execution:

cp -p ~/.claude/CLAUDE.md.bak-standard-<timestamp> ~/.claude/CLAUDE.md
cp -p ~/.codex/AGENTS.md.bak-standard-<timestamp> ~/.codex/AGENTS.md
cp -p ~/.gemini/GEMINI.md.bak-standard-<timestamp> ~/.gemini/GEMINI.md
cp -p ~/.agent-coordination/AGENT_COORDINATION.md.bak-standard-<timestamp> ~/.agent-coordination/AGENT_COORDINATION.md
cp -p ~/.agent-coordination/ACTIVE-DIRECTIVES.md.bak-standard-<timestamp> ~/.agent-coordination/ACTIVE-DIRECTIVES.md

Outstanding Owner Actions

None. All actions were reversible, pre-authorized under Rule 9/Rule 36, fully verified against reality, and mirrored to the hub.
