rdmbair15m5-changelog-20260923-1010-feat-20260831-06-autonomous-ticket-resolution

Delivered autonomous LLM-assisted issue and ticket resolution engine in Tyrell (FEAT-20260831-06), featuring pre-flight safety boundaries, model tier assignment, worktree isolation, automated test verification gates, and CLI integration.

Scope

• Hosts: rdmbair15m5 (execution/tests), rdmsm4x (canonical repo and ticket store)
• Repos: apps/Tyrell (commit a2e6490), issues (commit 217fcf1)

Files Touched

• apps/Tyrell/Sources/TyrellCore/Tickets/AutonomousIssueResolver.swift (created)
• apps/Tyrell/Tests/TyrellCoreTests/AutonomousIssueResolverTests.swift (created)
• apps/Tyrell/Sources/tyrell/Tyrell.swift (added resolve-auto CLI subcommand and usage string)

Implementation Details

1. Pre-Flight Authority Boundary: Enforces "The Four True Exceptions" to prevent unguided execution on physical hardware/keychain prompts, real financial spend, established decision overrides, or irreversible destructive deletion.
2. Model Tier Selection: Intelligently routes tasks based on severity and type across Haiku (triage/investigation), Sonnet 5 (reversible ops), Opus 5 High (interactive implementation), Opus 5 Max (irreversible release gates), and Fable 5.1 Max (oversight).
3. Isolated Worktree Lifecycle: Automatically allocates temporary worktrees via ECSWorktreeManager and cleans them up post-run.
4. Verification Gates: Runs baseline swift test before and after modifications, enforcing zero regressions.
5. CLI Face: Added tyrell ticket resolve-auto <ID> [--repo <path>] [--as <who>] [--dry-run] [--json].

Verification Evidence

• swift test --filter AutonomousIssueResolverTests: 3/3 tests passed in 0.022s (testDryRunExecution, testPlanResolutionModelTierMapping, testTheFourTrueExceptionsEscalation).
• swift test --filter TyrellTicketEngineTests: 5/5 tests passed in 0.019s.
• swift build --target tyrell: built cleanly in 0.82s.
• CLI execution: .build/debug/tyrell ticket help correctly lists resolve-auto.
• FEAT-20260831-06 resolved and moved to resolved/ in issues store on rdmsm4x.
• Commits pushed to origin, fleet, and backup remotes.
