`create:finish` leaves the merge local until `create:release` pushes it, so
`main` is routinely ahead of its upstream between a merge and a release. The
branch front door demanded an exact match and refused until it was pushed,
forcing a manual `git push` that the model deliberately keeps out of it.
Reject only a `main` that is behind its upstream — matching `create:finish`,
which already tolerates being ahead — and record why pushing from `finish` was
rejected instead. The push stays with `create:release`, so the merge remains
reviewable locally, and the known issue about the deadlock is gone.
Resolves: backlog task "Resolve the finish/push tension".
A merged branch must carry a final commit adding a short summary of the
work under [Unreleased] in CHANGELOG.md. create:release derives the bump
heuristic from that body, so notes have to exist before release day;
rationale in development/workflow.md.
Same decisions, rationale, rejected alternatives and known issues, said with
less padding: ~5,530 -> ~4,730 words (-15%). Every fact from the first draft is
kept; only the wording, duplicated lead-ins and restated context are cut.
The GitHub Flow description and the type-first enforcement sentence still
appeared in both CONTRIBUTING.md and development/. development/ now carries only
the context and rationale that is not in CONTRIBUTING.md.
development/ had restated the actionables that CONTRIBUTING.md owns: the
branching step list, the script prefix list, the feedback-tier rule of thumb,
the commit convention and the type-driven test loop. Those now live only in
CONTRIBUTING.md; development/ keeps the decision blocks and links to the rule.
development/README.md, CONTRIBUTING.md and AGENTS.md state the 'write each fact
once' principle explicitly.
Category files under development/ replace the decision prose that was
scattered through README.md and CONTRIBUTING.md. Each decision is a block with
Decision (YYYY-MM) / Why / Rejected / Known issue; the new library.md records
the public API contract and its limitations. AGENTS.md and backlog.tasks now
point at the new home.
