Legacy SHA arrays are populated from the returned OIDs so the transitional fields stay intact. +- Post-commit hook now builds a libgit2-backed `gm_git_repository_port` instead of poking `ctx->git_repo`; journal helpers lean solely on ports and clean up the adapter after processing. +- Hook journey note: fake git port fuels the edge tests; with augment helpers on the seam, the remaining hook work is porting merge detection and retiring the legacy `git_ops` shim. +- Augment helpers now resolve HEAD/parent blob OIDs through the repository port (new `resolve_blob_at_commit` seam), and the fake git adapter learned commit-scoped blob mapping so tests can assert hook behavior without libgit2. +- Architecture doc updated (`docs/architecture/augments-system.md`) with the post-commit ➜ repository-port wiring so future hooks keep the seam intact. +- Merge detection runs through the port too: added `commit_parent_count`, rewired the post-commit hook to create/dispose the port up front, and landed a `test_hook_augment` suite that exercises HEAD/parent blob lookups and merge detection via the fake adapter. +- `gm_context_t` is now strictly port-based—dropped the legacy `git_ops`/`git_repo` shim, handed raw libgit2 ownership to the CLI runtime, refreshed cache/journal tests, and kept the new shape green with `make ci-local`. +- Next up: finish scouring CLI + bench utilities for direct libgit2 calls, port them behind adapters, and keep clang-tidy quiet while we prep the PR. +- Lesson logged: mirroring libgit2 semantics meant storing commit sequences per ref; keeping messages alongside the OIDs made the reader decode deterministic again. +- Cap’n memo: espresso's on deck—once edge jumps ports, we raid the galley for celebratory biscotti. +- Filesystem tidy sweep: replaced the lingering raw `memset` calls in `gm_fs_path_dirname`/`gm_fs_path_basename_append` with `gm_memset_safe`, added the explicit `separator_len` so the bool math stops tripping clang-tidy, and pulled in the security header for the helper prototypes. +- POSIX temp adapter now defines `_GNU_SOURCE` up front and trusts glibc's `realpath`; the redundant extern declaration is gone, keeping include-cleaner + tidy happy. +- Immediate next move: rerun `make ci-local` once these filesystem fixes settle, then chase the remaining bool-to-int clang-tidy nits in the staged benchmark + fake git port files before we go PR hunting. +- Lesson logged: tidy catches implicit bool arithmetic fast—introducing small helper variables beats sprinkling casts and keeps the intent readable for future hex refactors. +- Message in a bottle: future Cap’n, there’s cocoa in the galley—sip it while you double-check the tidy report before raising the PR flag. +- CodeRabbit pass (batch 2): accepted output-zeroing and error-propagation notes—commit creation now clears result OIDs up front, commit message reads null-init outputs, hook blob lookups zero result buffers and distinguish NOT_FOUND from real failures, commit walks honour `GM_CALLBACK_STOP`, and the fake port header owns its std includes. +- CodeRabbit pass (batch 3): reaffirmed the wildebeest benchmark already routes queries via `gm_oid_t`, clarified detached-HEAD fallback inside `gm_hook_get_blob_sha`, and brought the PR171 review docs in line with the front-matter/TOC guidelines. + ## Next Steps (handoff checklist) - Complete on-disk cache migration to OID-only storage and naming;

It fails to highlight the most significant refactoring or feature change that a reviewer should notice when scanning PR titles. | Please update the title to a concise sentence that reflects the main change, for example “Introduce gm_git_repository_port abstraction and migrate core Git operations to use it.” | +| Description Check | ⚠️ Warning | The description is a flat list of commit scopes and messages rather than the structured template required by this repository, and it omits the “## Summary,” “## Change Areas,” “## Risk,” and “## Code Review Guidance” sections along with their expected content and checkboxes. As a result, reviewers cannot easily see the rationale, affected areas, risk assessment, or guidance for reviewing this PR. | Please rewrite the description to follow the repository’s template by adding a “## Summary” explaining why these changes are needed, populating the “## Change Areas” and “## Risk” sections with checkboxes, and including the “## Code Review Guidance” block to guide reviewers. | +| Docstring Coverage | ⚠️ Warning | Docstring coverage is 8.91% which is insufficient. The required threshold is 80.00%. | You can run `@coderabbitai generate docstrings` to improve docstring coverage. | + +
