Re‑assert the History Ordering Invariant (No Behavioral Change Intended) + +**Goal**: Treat the ordering of history writes vs. git commits as a non‑negotiable +invariant and make the expected behavior fully observable and testable. + +1. The required behavior remains: + - `history::write_git_commit(&plan_dir, summary)` (or equivalent) must always be + called **before** any function that can perform a git commit (e.g. + `git::commit(&codepath, summary, description)`). + - If the commit later fails, the `GIT COMMIT ()` entry must still remain + in `planner_history.txt`. + - The `` written to history must exactly match the commit summary passed + to `git::commit`. +2. Treat this as a **hard invariant** for planner‑mode commits and document it in + code comments where the behavior is enforced. +3. No change in the user‑visible semantics is desired here; the purpose of these + requirements is to make the invariant harder to accidentally violate and easier + to verify. + +## 2. Verify `append_entry` Is Not the Root Cause + +The user speculates that flushing might be needed in the helper that appends to +`planner_history.txt`: + +```rust +/// Append an entry to planner_history.txt +fn append_entry(plan_dir: &Path, entry: &str) -> Result<()> { + let history_path = plan_dir.join("planner_history.txt"); + + let mut file = OpenOptions::new() + .create(true) + .append(true) + .open(&history_path) + .context("Failed to open planner_history.txt for appending")?; + + writeln!(file, "{}", entry) + .context("Failed to write to planner_history.txt")?; + + Ok(()) +} +``` + +**Requirements**: +1. Locate the actual implementation of `append_entry` (or equivalent) in + `crates/g3-planner` and confirm it behaves as above (OpenOptions with + `.append(true)` and a single `writeln!`). +2. Decide whether an explicit flush is necessary: + - If the file handle is dropped immediately after `writeln!`, an additional + `file.flush()` is **not** expected to change durability semantics for normal + operation, but adding it is acceptable if it simplifies reasoning. + - If the file handle is reused across multiple calls or buffered beyond the + scope of `append_entry`, add an explicit `file.flush()` before returning and + document why. +3. Record the conclusion in a short code comment **inside** `append_entry` to make + clear that the function is not responsible for the observed ordering bug in + planner history (which is about **call order**, not I/O buffering), unless you + have strong evidence to the contrary. + +## 3. Git History Analysis: Confirm the Regression Story + +These requirements complement the earlier investigation requirements by +emphasizing a sanity check against the most recent regression. + +1. Re‑use (do not duplicate) the existing investigation logic that finds: + - The commit that moved `write_git_commit` after `git::commit`. + - The later commit that restored the correct order. +2. For the current regression that prompted these requirements, confirm via `git + log -p` on `crates/g3-planner/src/planner.rs`: + - That `stage_and_commit()` (or any wrapper that performs commits) currently + calls `write_git_commit` before `git::commit`. + - That any temporary reordering that reintroduced the bug is now gone. +3. Update the existing external note / explanation (from the previous + requirements) with a **one‑sentence addendum** that explicitly mentions this + latest regression was again caused by call‑order changes, not by I/O buffering + in `append_entry`. + +## 4. Explicit End‑to‑End Verification Using a Throwaway Repo + +**Goal**: The planner behavior must be verified end‑to‑end in an isolated test +repository so that both the human user and the coach can see evidence that the +history/commit ordering is correct. + +1. Create a throwaway git repository at `/tmp/commit_test`: + - Initialize a repo: `git init /tmp/commit_test`. + - Create a minimal, valid Rust or placeholder project that allows running g3 + in planning mode against it. +2. Run g3 **in planning mode** with that repo as the codepath (and a workspace of + your choice), using the recommended CLI flags from previous requirements. +3. Go through a minimal planning cycle that performs a **successful** commit from + planner mode. +4. After the commit: + - Inspect `/tmp/commit_test/g3-plan/planner_history.txt`. + - Confirm that the **last history entry at the time of the commit** is a + `GIT COMMIT ()` line, and that `` matches the actual git + commit summary. +5. Save the exact shell commands used and the relevant excerpt of + `planner_history.txt` (last ~10 lines) in a short note (e.g. a comment block + in `planner_history.txt` or a separate markdown file under `g3-plan`) so that + the coach can verify the test was truly executed. +6. These verification artifacts are for humans; the application itself does not + need to parse or enforce them. + +## 5. Strengthen Guardrails Against Future Regressions + +These guardrails build on those already specified in +`completed_requirements_2025-12-10_16-55-05.md` and should be updated rather +than duplicated. + +1. In the **same location** where you previously added the comment explaining the + ordering requirement above `write_git_commit` in `stage_and_commit()`, extend + the comment to explicitly reference: + - That this ordering has regressed multiple times + - That changes to staging/committing logic **must** keep `write_git_commit` + before `git::commit`. +2. If not already done, ensure there is at least one test in + `crates/g3-planner/tests/` that: + - Uses a fake/simulated `git::commit` implementation. + - Asserts that `write_git_commit` is invoked before the fake commit function. + - Fails loudly if the order is reversed. +3. Make sure any new helper function that performs commits (e.g. a shared + `commit_with_history()` function, if introduced) encapsulates the invariant: + - Callers **must not** be allowed to call `git::commit` directly from planner + mode without going through the history‑aware helper. + +--- + +{{ORIGINAL USER REQUIREMENTS -- THIS SECTION WILL BE IGNORED BY THE IMPLEMENTATION}} + +Despite the previous fix, the COMMIT.
