Gantry moved finish-time merge repair from engine-specific paths into a selected pattern while retaining the engine's integration bracket. The resulting tree carries a bundled merge pattern, selection and frozen-closure handling, pattern invocation during finish, and records updated for that route.
How this walkthrough is structured
Feature
What did the run build and ship?
The current tree expresses merge repair through bundled patterns and an engine-owned finish bracket.
Build
How did Gantry structure the work?
The run separated the contract, selection, invocation, and record changes into four green milestones.
Milestone 1
Pattern Contract
2 tasks 9 agents 44m 11s wall time 227k peak context
The bundled pattern files now declare merge selection and share `troubleshoot.toml` across the entry patterns that need it. The published reference data describes the bundled merge and troubleshoot patterns. Current configuration and reference files therefore retain the contract this milestone described.
The brief made the pattern-format contract and bundled corpus carry merge repair as ordinary pattern execution. It grouped specification, composition, shared troubleshooting, and documentation work at one boundary. The ledger records this milestone green. The run facts do not attribute stages or review results to this milestone, so they do not locate further stress here.
Milestone 2
Merge Selection
4 tasks 14 agents 1h 26m wall time 245k peak context
`bind_selected_merge_pattern_invocation` resolves an explicit selection, a declared merge pattern, or the bundled default. The resume path reads a merge-pattern pin and backfills the bundled invocation when the frozen closure needs it. The CLI reference retains the `--merge` selector while preserving `gantry merge` as the partial-merge verb.
This milestone made a merge pattern resolvable before finish-time reconciliation needs one. Its brief kept selector handling, defaulting, parameter binding, and frozen-closure backfill in the same unit. The ledger records it green. The run facts provide no milestone attribution, so they cannot identify a local retry or review rejection.
Milestone 3
Merge Invocation
4 tasks 17 agents 2h 38m wall time 244k peak context
The finish implementation obtains the selected merge invocation and supplies engine-derived merge inputs to it. Its merge loop handles conflicted, residue, gate-red, and reintegrate states while retaining refusal and attempt information. The current code also rejects a conflicted return that leaves `MERGE_HEAD` present or lacks an integrate commit.
The brief assigned the engine bracket and the selected merge pattern distinct responsibilities during finish-time reconciliation. It concentrated merge states, refusals, stop handling, and resume behavior where one agent could reason about their boundary. The ledger records it green. The run facts do not assign stage outcomes to this milestone, leaving no recorded unit-local stress.
Milestone 4
Merge Record
5 tasks 19 agents 2h 39m wall time 242k peak context
The current finish path invokes a selected merge pattern and archives its resolver logs after a completed merge. Simulation code and the reference data remain among the files changed by the run. The absence of every prior merge implementation cannot be established from the supplied git facts alone, but the current finish code carries the selected-pattern route named by the brief.
The final milestone was the cleanup and record boundary for the pattern-driven merge path. Its brief covered removal of prior merge implementations together with tests, simulation, reference data, and documentation. The ledger records it green. The run facts contain no milestone-local stages, recoveries, or review findings for this unit.
