This run restored a shipping-target dead-code lint, then used that signal to remove retired code and finish related ownership moves. Its milestones separate the enforcement rule, the removals, pattern-reference validation, live API consolidation, and module structure.
How this walkthrough is structured
Feature
What did the run build and ship?
The current tree retains the shipping lint, its release-pattern validation, and the later module surfaces that carry the cleanup forward.
Build
How did Gantry structure the work?
The cut made production reachability enforceable before dividing the resulting cleanup across focused ownership boundaries.
Milestone 1
Lint Signal
1 tasks 7 agents 39m 24s wall time 199k peak context
The root test script still runs clippy against the shipping binary in stripped configurations. The test-reliability analysis still explains why that tier omits test targets and what dead code it catches. The production check and its rationale remain together in the tree.
The cut placed a shipping-target lint tier before the cleanup, giving later removals a production check to answer to. Its brief isolates stripped configurations and test-only reachability from the broader deletion work. The ledger records the milestone green, while the measured run record does not attribute gate or review events to this milestone.
Milestone 2
Dead Code Cleanup
8 tasks 22 agents 2h wall time 208k peak context
The diagram remains split into API, layout, paint, and widget modules, with module documentation at those boundaries. Retired animation access and the former TUI state file are absent from the current tree. The broader removal set cannot be isolated further from the current git facts, which report the run rather than individual cleanup decisions.
Dead Code Cleanup separated removal of retired surfaces and stale suppressions from the rule that exposed them. The brief gave the work explicit limits: preserve live behaviour and retain named contracts at their live locations. The ledger marks the boundary green, but the run record supplies no milestone-local account of stress or recovery.
Milestone 3
Pattern Invocations
1 tasks 7 agents 27m 25s wall time 213k peak context
Raw pattern reference discovery currently returns direct include references only. Its source documentation states that call and for targets are validated in the composed definition namespace. A current test loads the release pattern through the bundled-pattern lookup, so that boundary remains exercised.
Pattern Invocations confined the historical question about invocation discovery to a dedicated milestone. Its brief required a history check before either restoring a contract or retiring it, then required bundled-pattern validation. The ledger records completion without a recovery, and the run record gives no milestone-local stage attribution.
Milestone 4
Live Shape
5 tasks 15 agents 1h 9m wall time 121k peak context
The current text module collapses blank input when its caller requests collapsed blank lines. The TUI state imports its devtools-only modal dispatch behind the matching configuration condition. Those surviving seams show the ownership and feature-boundary work, while the git facts do not isolate every consolidation named by the brief.
Live Shape grouped retired representations and duplicate implementations by the modules that own their meaning. The brief made compatibility and named latent behaviour changes the boundary, rather than treating a broad refactor as its own result. The milestone is green in the ledger; the available run facts cannot locate a gate result or review finding within it.
Milestone 5
Module Structure
5 tasks 15 agents 1h 46m wall time 175k peak context
The current command reference exposes the devtools tour as `gantry --tour`. The mock-agent surface remains behind test or devtools configuration, and the stats CLI now asks the run-state value for its label directly. Those current surfaces confirm the flag and ownership changes; the present tree does not isolate every module move listed in the brief.
Module Structure followed the lint and live-shape work with the ownership moves named by the plan. Its brief kept public behaviour stable apart from the devtools flag rename, giving the structural changes a defined compatibility boundary. The ledger records a green result, but the run facts provide no milestone-specific stage history.
