Fourth and final family extraction. A pure behaviour-preserving move: the mutating checkout verbs -- update, bisect, merge, revert, undo, redo, commit, amend -- and the helpers private to them (the undo journal, the dirty-tree gate, the checkout record, the commit and amend manifest assembly) move verbatim into src/cmd/checkout.zig, byte-identical to their source but for the pub the dispatch forces on the eight handlers. commitEpoch stays in main.zig because main itself builds the ambient clock from it; shared helpers stay pub and aliased. With this, main.zig holds only main, the verb dispatch, init, the shared helpers and the test surface -- the eleven-thousand-line file is now four cmd families plus a thin dispatch core. No helper duplicated, no cross-cmd import, test count unchanged. check-in: ae54e47b3c user: dmestas tags: trunk

The final family extraction, completing the split of the CLI surface out of main.zig. A pure behaviour-preserving move: the mutating verbs -- update, bisect, merge, revert, undo, redo, commit, amend -- and the helpers and tests private to them move verbatim into src/cmd/checkout.zig, byte-identical to their source but for the pub the dispatch switch forces on the eight dispatched handlers.

The move is non-contiguous: the update error mapper, the digest wire helpers, mintControlArtifact, and commitEpoch stay in main.zig because they are shared with other verbs or with main itself, so moving them would cross a cmd boundary or duplicate them. Shared helpers stay pub and are aliased so the moved bodies read unchanged. No helper duplicated, no cross-cmd import, test count unchanged.

After this, main.zig retains only main, the verb dispatch, runInit, the genuinely shared helpers, and the test helpers. closed check-in: 9870033d32 user: dmestas tags: s5-checkout

Third of four family extractions. A pure behaviour-preserving move: the read surface -- stat, log, leaves, timeline, branch, tag, info, ls, cat, artifact, annotate -- and the name-resolution and rendering helpers private to it move verbatim into src/cmd/history.zig, byte-identical to their source but for the pub the dispatch switch forces on the eleven handlers. The extraction is non-contiguous: the mutating checkout verbs interleave with the read verbs in the file and stay exactly in place. repoReadFail stays pub in main.zig because the sync family calls it, so moving it would cross cmd boundaries. Shared helpers stay pub and aliased so moved bodies read unchanged. No helper duplicated, no cross-cmd import, test count unchanged. check-in: 3bbc572acd user: dmestas tags: trunk
