+{{CURRENT REQUIREMENTS}}
+
+These requirements refine planner history handling in `g3-planner`, focusing on ensuring
+that `planner_history.txt` consistently records git commit entries **before** the actual
+`git commit` is executed, and on understanding how this invariant was previously lost.
+
+## 1. Guarantee `GIT COMMIT` History Entry Precedes the Commit
+
+**Goal**: In planning mode, every successful git commit initiated by the planner must have a
+corresponding `GIT COMMIT (<MESSAGE>)` line written to `<codepath>/g3-plan/planner_history.txt`
+*before* the commit is attempted.
+
+**Current behavior (as of this revision)**:
+- `crates/g3-planner/src/planner.rs`, function `stage_and_commit()` already contains:
+  - A call to `history::write_git_commit(&config.plan_dir(), summary)?;` immediately before
+    calling `git::commit(&config.codepath, summary, description)?;`
+- This matches the intended ordering, but a previous version had the history write *after* the
+  commit. That bug was later “fixed” and then reintroduced once during refactors.
+
+**Required behavior**:
+1. Treat the ordering as a strict invariant for all planner-driven commits:
+   - `planner_history.txt` must always be updated with a `GIT COMMIT (<MESSAGE>)` line
+     **before** calling any function that performs the actual `git commit`.
+2. If the commit fails (e.g. git returns error), the `GIT COMMIT` history entry must still
+   remain in `planner_history.txt` to reflect the attempted commit.
+3. The summary string written to history must match the actual commit summary used in
+   `git::commit()`.
+
+**Acceptance criteria**:
+- Static inspection: in `stage_and_commit()` (and in any future helper functions that might wrap
+  it), the call order is unambiguous and there is no path where `git::commit` can run without the
+  preceding `write_git_commit` call.
+- Behavioral: in a test/planning run, intentionally cause the commit to fail (e.g. by breaking
+  git config) and verify that:
+  - A new `GIT COMMIT (<MESSAGE>)` line appears in `planner_history.txt`.
+  - No commit is created in git.
+
+## 2. Identify How the Ordering Bug Was Previously Undone
+
+**Goal**: Understand how the previously-correct ordering was lost so that future changes avoid
+reintroducing the same bug.
+
+**Investigation requirements**:
+1. Use `git` history to find the commit that originally moved `history::write_git_commit` to *after*
+   `git::commit` inside `stage_and_commit()`:
+   - Search for changes to `crates/g3-planner/src/planner.rs`, function `stage_and_commit`.
+   - Identify the commit SHA, author, and commit message where the order became incorrect.
+2. Identify the later commit that restored the correct order (writing history before commit):
+   - Record the SHA and message for the fix.
+3. Summarize in **one short paragraph** (kept outside of the code, e.g. in a planning note or
+   as a comment in `planner_history.txt` via a dedicated entry) **why** the ordering regressed.
+   Possible root causes to look for:
+   - Refactorings that moved staging/commit logic but did not preserve history semantics.
+   - Changes that tried to “simplify” logging and accidentally rearranged calls.
+   - Copy‑paste from an older version of `stage_and_commit`.
+
+**Output expectations** (for the human operator, not the code):
+- A concise explanation along the lines of:
+  - “Commit `<SHA1>` refactored `stage_and_commit` and inadvertently moved
+     `write_git_commit` after `git::commit`. Commit `<SHA2>` later corrected this by
+     restoring the original order. The regression was caused by copying the older
+     implementation from `<file/branch>` without re‑applying the earlier fix.”
+
+## 3. Guardrails to Prevent Future Regression
+
+**Goal**: Make it harder to accidentally reintroduce the wrong ordering of history vs. commit.
+
+**Required changes**:
+1. Add a short, explicit comment directly above the `write_git_commit` call in
+   `stage_and_commit()` explaining the ordering requirement, for example:
+   - `// IMPORTANT: Write GIT COMMIT entry to planner_history BEFORE actually running git commit.`
+   - `// This is relied on for audit trail and for post‑mortem analysis when commits fail.`
+2. Add a lightweight test around `stage_and_commit()` (or a thin wrapper) that asserts the
+   intended behavior at a higher level, such as:
+   - Using a fake or test double for `git::commit` and `history::write_git_commit` to ensure
+     `write_git_commit` is invoked first.
+   - This test should live in `crates/g3-planner/tests/` and not depend on a real git repo.
+3. Document the invariant in planner‑mode requirements (this document) so that future
+   requirement refinements and implementations continue to emphasize:
+   - “Always write `GIT COMMIT (<MESSAGE>)` to planner_history.txt before performing the
+      actual `git commit`.”
+
+---
+
+{{ORIGINAL USER REQUIREMENTS -- THIS SECTION WILL BE IGNORED BY THE IMPLEMENTATION}}
+
+
+The bug you previously fixed has reappeared. Make SURE the "COMMIT" line to the planner_history
+is added BEFORE you make the commit.
+
+Check the history for the previous fix, and identify why the fix was undone?

+## Investigation Summary
+
+Commit ff8b3e7c7b3bf89c140d24b6f59e443a4f9db0d8 (2025-12-09) initially implemented
+planning mode with the history write AFTER the git commit. Commit 633da0d8a685f462c4a74fb5f7b63e4de50596bf
+(also 2025-12-09, later the same day) corrected this by moving the history write BEFORE
+the commit, with the comment "Log commit to history BEFORE making the commit (provides
+audit trail even if commit fails)". The current HEAD maintains this correct ordering.
+
+## Root Cause Analysis
+
+The bug was introduced during the initial implementation of planning mode. The original code
+placed the history write after the git commit, which meant that if the commit failed (e.g.,
+due to git configuration errors, network issues, or missing staged files), no audit trail
+would exist in planner_history.txt. This was quickly identified and fixed the same day.
+
+The fix could potentially be undone during future refactoring if developers are not aware
+of the critical ordering requirement. This is why we have added:
+
+1. Comprehensive inline documentation explaining the invariant
+2. Historical context in comments referencing the original bug
+3. A comprehensive test suite that validates the ordering under various failure scenarios
+4. Clear warnings against moving the history write after the commit
+
+## Implementation Complete
+
+All tasks completed successfully:
+- Enhanced comments in planner.rs with CRITICAL INVARIANT documentation
+- Created comprehensive test suite (5 tests, all passing)
+- Tests cover: empty staging, successful commits, failed commits, multiple entries, format validation
+- Ordering invariant is now explicitly documented and tested
