Release 2.1.166 (2026-07-25)¶

Bug fixes¶

source vergil.toml from develop, never main (#2532) vrg-github-repo-config read the canonical vergil.toml from main ahead of develop, so a config change merged to develop was silently ignored by apply until a release carried it to main — and main may not exist in an unreleased repo. Config now tracks the default branch (develop), matching how GitHub runs workflows off the default branch. main is dropped entirely, not merely reordered: under GitFlow, content reaches main only via develop, so main can never hold a vergil.toml that develop lacks — a main fallback could only ever return the same file or a staler one. The local working-copy bootstrap fallback is unchanged. Ref #2530.

make the retrospective the terminal bookend in the epic-lifecycle standard (#2533) Spawned by epic #201's documentation-review sweep. Rewrites the bookend convention: the retrospective is the terminal bookend / final gate that closes the epic, documentation-review runs before it, and the follow-on brainstorm is semi-optional (no longer the closing act). Adds the three-skill lifecycle (epic-create -> epic-implement -> epic-retrospective) to the Creating-an-epic section. Refs vergil-project/.github#201.
