…1014) ## Summary The intent-staleness advisory (`check_intent_staleness`/`hub_last_change` in `spec/audit.py`) compared two dates and read no content at all: a downstream copy's last commit against the hub canonical's last commit. The verbatim engine already normalizes three classes of governed drift before hashing (`spec/fidelity-model.md` "Normalization"): line endings, a `uses: <action>@<sha>` pin with its trailing version comment, and a job's `needs:` list. The intent advisory applied none of that, so a Dependabot pin bump on a workflow file's hub canonical marked every downstream carrier as "possibly trailing" at once, for a class of drift the fidelity model already treats as governed per-repo churn rather than a deviation. ## Fix `hub_last_change()` now walks the canonical's full git history and returns the newest revision whose normalized content differs from its predecessor's (`_last_effective_change`), falling back to the file's creation revision if every bump back to it was normalized-only. `git_file_history()` and `hub_last_change()` now share one cached history walk (`_git_revisions`) instead of two separate `git log` calls. Verified live against the two files named in the issue: `publish-release.yml` now dates from a real job-condition change (#844) instead of the pin-only Dependabot bump (#612) the issue measured, and `validate-task.yml` picks up its most recent real change. Added self-test coverage for `_last_effective_change` (pin-only chain back to creation, a real change under a later pin bump, a single-revision file, and unreadable history treated as effective rather than silently skipped). Updated the `fidelity-model.md` "intent" description and the `check_intent_staleness`/`hub_last_change` docstrings to state the normalization explicitly. ## Validation - `python3 spec/audit.py --selftest` (includes the new `_last_effective_change` cases) - `ruff check` / `ruff format --check` / `mypy` on `spec/audit.py` - `python3 scripts/prose_lint.py` - `python3 scripts/repo_gate.py` - `python3 scripts/host_gate.py` - Live-checked `hub_last_change()` against `publish-release.yml` and `validate-task.yml`, confirming the returned commit is a real content change, not the Dependabot pin bump.

- Around line 1726-1732: Update the audit history and canonical-content reads
around the git-log invocation to use an audit-owned checkout refreshed from the
hub’s main branch immediately before reading. Ensure hub_last_change and
check_intent_staleness derive exclusively from that main checkout, while keeping
the audit read-only and avoiding the current HEAD or working checkout.
- Around line 1721-1722: Update the git show handling in git_file_history to
distinguish a confirmed deleted path from command execution failures: return
None only when the revision explicitly indicates the path is absent, and
otherwise raise an execution error containing the path, SHA, and stderr.
Preserve deletion handling while preventing failed revisions from being treated
as history changes, and revise the related self-test to cover the
confirmed-deletion boundary rather than accepting a generic git show failure.

## Summary
`_git_revisions()` (spec/audit.py) converted every non-zero `git show
<sha>:<path>` into `text=None` alike: a confirmed deletion (the commit
came from `git log -- <path>`, which includes the commit that removed
the path, so `git show` correctly finds nothing there) and a genuine
command fault (a corrupt object, a permission or encoding fluke) read
the same way. A real failure could silently pass as an ordinary deletion
instead of surfacing as the tool fault it is.
## Fix
`git show`'s stderr for a confirmed deletion is stable ("fatal: path
'<path>' does not exist in '<sha>'"), verified empirically against a
real deleted-then-committed file in a throwaway repo. Match on that
phrase to keep the None path for a deletion; raise `RuntimeError` with
the path, sha, and stderr for anything else, matching the existing `git
log` failure handling one function up.
Added a self-test that builds a throwaway git repo with a deleted file
and confirms the deletion revision reads as None without raising.
## Validation
- `python3 spec/audit.py --selftest`
- `uvx ruff check` / `uvx ruff format --check spec/audit.py`
- `uvx mypy spec/audit.py`
- `python3 scripts/prose_lint.py` (full check set)
- `python3 scripts/repo_gate.py`
- `python3 scripts/host_gate.py --repo .`

## Summary `git ls-tree` only proved rel_path had *some* entry at a revision, not that the entry was a regular file: a file-to-directory transition (a canonical path later replaced by a directory of the same name) still returns a non-empty ls-tree line, so the code proceeded to `git show`, which succeeds on a tree path and returns a directory listing, not file content. That listing would then be hashed and compared as if it were the file's real text. ## Fix Parse the ls-tree entry's type field and only treat rel_path as present when it is `blob`. Anything else (a tree from a file-to-directory transition, a commit gitlink from a submodule) reads the same as absent. Added a self-test covering the file-to-directory transition. ## Validation - `python3 spec/audit.py --selftest` - `uvx ruff check` / `uvx ruff format --check spec/audit.py` - `uvx mypy spec/audit.py` - `python3 scripts/prose_lint.py` (full check set) - `python3 scripts/repo_gate.py` Raised by CodeRabbit on PR #1016 (develop -> main promotion). 🤖 Generated with [Claude Code](https://claude.com/claude-code) <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **Bug Fixes** * Improved audit handling when a tracked file is replaced by a directory or submodule. * Such transitions are now processed safely without treating them as file content. * Added coverage for file-to-directory changes in the self-test suite. <!-- end of auto-generated comment: release notes by coderabbit.ai -->

## Summary A symlink's `git ls-tree` type is `blob` too, the same as a regular file: only its mode (120000) differs. Checking entry type alone let a file-to-symlink transition through as file content, and `git show` on a symlink revision returns the link's target path string, not the content it points to, so that string would be hashed and compared as if it were the file's real text. ## Fix Check the ls-tree mode field directly instead of the type: only `100644` (regular) and `100755` (executable) count as file content, everything else (`040000` tree, `120000` symlink, `160000` gitlink, or absent) reads as None. Added a self-test covering a file-to-symlink transition. ## Validation - `python3 spec/audit.py --selftest` - `uvx ruff check` / `uvx ruff format --check spec/audit.py` - `uvx mypy spec/audit.py` - `python3 scripts/prose_lint.py` (full check set) - `python3 scripts/repo_gate.py` Raised by CodeRabbit on PR #1016 (develop -> main promotion). 🤖 Generated with [Claude Code](https://claude.com/claude-code) <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **Bug Fixes** * Improved handling of historical symlinks, directories, and submodules during audit comparisons. * Prevented unsupported path types from being treated as readable file content. * Added coverage for symlink transitions in audit validation. <!-- end of auto-generated comment: release notes by coderabbit.ai -->
