PR #776 (seventh merge wave + bare-main rule shard) squash-merged onto main at 04:56:15Z. 17 PRs total this session arc. PR #775 round-2 thread fixes pushed: (a) P1 internal inconsistency between "never use bare main" rule and the local-main-tracking-origin example using `git switch main` — fixed with explicit clarification that bare `git switch main` is safe ONLY when `refs/heads/main` exists locally and tracks origin (Git's lookup order finds the local ref first); all other refs in the example reframed to fully-qualified `refs/remotes/origin/main` form; (b) P2 misread `channel:` label — was prose continuation, not a frontmatter field; inlined to "forwarded by Aaron through the maintainer channel (the live Claude Code CLI conversation surface):" so no apparent label exists; (c) P1 MEMORY.md entry too long — trimmed from full paragraph to one-liner per memory/README.md ~200-line cap discipline; detailed content remains in the dedicated memory file. Amara's round-2 packet additions also landed in the same commit: **hard-stop pattern** (`set -euo pipefail` + explicit `exit 1` on base-ref failure — Amara's actual catch was "fatal happened, loop continued", not just bare-main ambiguity); **better fetch refspec form** `refs/heads/main:refs/remotes/origin/main` to ensure remote-tracking-ref refresh; **pre-canonization search evidence section** recording the actual search terms used + the closest-hit non-fit, so future-Claude can audit the search-before-canonizing decision. All 3 PR #775 threads resolved. | [#776 merged](https://github.com/Lucent-Financial-Group/Zeta/pull/776), [#775 round-2](https://github.com/Lucent-Financial-Group/Zeta/pull/775) | Trajectory observation: this tick demonstrated the bare-main rule's self-application AND the hard-stop pattern (the branch creation used `git switch --detach refs/remotes/origin/main || { echo "failed..."; exit 1; }` — the rule applied to its own creation event). The Amara round-2 packet also surfaced an important meta-finding: the rule needs to address not just ambiguity but the failure-continuation that makes ambiguity dangerous. The keeper "Multiple mains are topology. Bare main in automation is ambiguity. Continuing after fatal base-ref failure is the actual bug." captures the full failure mode — the bug was always the continuation, not just the ambiguity. |
