Documented the rdmpw3275m Atlassian/GitLab MCP investigation as structured Tyrell reference data and delivered an identical embedded copy to claude@rdmsm4x through the fleet message bus.

Scope

• Origin host: rdmpw3275m.
• Recipient: claude@rdmsm4x.
• Intended downstream project: tyrell.app MCP catalog/reconciliation work.
• No Tyrell repository or canonical source tree was edited from this non-canonical host.

Changes

• Created /Users/richh/dev/_handoff/codex-out/tyrell-mcp-catalog-reference-20260825/rdmpw3275m-atlassian-gitlab-mcp-reference.md.
• The reference artifact records:
  • deterministic attribution of localhost:5598/oauth/callback to the former Atlassian SSE URL under mcp-remote;
  • a point-in-time state matrix separating local config, package/plugin, process, listener, auth cache, tool inventory, account connector, and desired state;
  • evidence locations and bounded probes;
  • a proposed Tyrell identity/observation data model;
  • reconciliation labels such as configured_idle, auth_required, broken_runtime, stale_inventory, historical_only, removed_verified, and unknown;
  • false-positive controls, process-argument redaction guidance, account/host scoping, and shared-runner safety.
• Sent the full artifact as fleet message 20260825-145816-DBE540CD with topic tyrell-mcp-catalog-reference and priority high to claude@rdmsm4x.
• Synchronized the immutable fleet mailbox to all reachable peers.
• Created this changelog file for the local durable record.

Commands and operations

• Created the bounded handoff directory under /Users/richh/dev/_handoff/codex-out/.
• Authored both files using patch-based file creation.
• Used /Users/richh/.agent-coordination/agent_msg.zsh send --file ... so the reference content is embedded in the immutable mailbox message rather than depending on the scratch-host path.
• Ran /Users/richh/.agent-coordination/agent_msg.zsh sync.
• Used read-only stat, shasum -a 256, and pattern checks locally, then verified the replicated message over read-only SSH on rdmsm4x.

Verification

• Handoff artifact size: 10,814 bytes.
• Handoff artifact SHA-256: ad1075f84faa73bb10bd9e6771e07801e138eac6d0180c184021ed796332470b.
• Embedded local mailbox message size: 11,059 bytes.
• Local mailbox message SHA-256: e4e8121c714fc3189c220299a2579d5814a0cb9a550fa4fd4a7d28fad20c8eb1.
• Remote rdmsm4x mailbox message size: 11,059 bytes.
• Remote rdmsm4x mailbox message SHA-256: e4e8121c714fc3189c220299a2579d5814a0cb9a550fa4fd4a7d28fad20c8eb1.
• The local and remote message hashes match exactly.
• The message contains the full callback-attribution payload, not merely a local path.
• A bounded scan for common API/token patterns found no secret value in the handoff artifact or mailbox copy.
• Fleet synchronization returned ok for rdmsm4x, rdmbair13m5, rdmbair15m5, rdmpw3265m, and jdmbair13m5.

Files touched

• Created: /Users/richh/dev/_handoff/codex-out/tyrell-mcp-catalog-reference-20260825/rdmpw3275m-atlassian-gitlab-mcp-reference.md
• Created locally and replicated immutably: /Users/richh/.agent-coordination/mail/20260825-145816-DBE540CD__from-codex-rdmpw3275m__to-claude-rdmsm4x__tyrell-mcp-catalog-reference.md
• Created: /Users/richh/dev/LLM/Claude/changelogs/rdmpw3275m-changelog-20260825-1459-relay-mcp-catalog-reference-for-tyrell.md

Backup and undo

• The immutable replicated fleet message is the durable handoff copy. The source artifact is a secondary scratch-host copy.
• No canonical Tyrell file was changed, so no source rollback is required.
• If the handoff is superseded, send a new immutable correction referencing message 20260825-145816-DBE540CD; do not mutate or delete the original fleet message.

Outstanding owner action

• claude@rdmsm4x should review and save/integrate the reference into Tyrell's canonical MCP catalog design or reference-data location. Delivery is verified; downstream integration is not claimed here.
