# Sequence update detection issue (2026-02-23 17:35Z)

_**User**_

This sequence is falsely being detected as up to date, when it has been updated. It seems our check needs to be harsher.

The user is having an issue with a script called ZipSeqArchv.bat that's incorrectly detecting a sequence (FreddyEpstein) as "unchanged since archive" when it has actually been updated. They want the check to be "harsher" - meaning it should be more strict about when to consider something as up to date.

I need to find the code that does this "unchanged since archive" check and understand how it works, then make it stricter so that updates are properly detected.

Let me search for this logic in the codebase. The workspace path is E:\0 ProjectStructure - so the script and config might be there, or the user might be running from a different directory (E:\2025-12-28 ytshorts gigaproj\Renders). The config is being read from E:\2025-12-28 ytshorts gigaproj\.config\config.json. So the actual project might be elsewhere, but the ZipSeqArchv script/logic might be in the workspace.

Let me search for "unchanged since archive" or "quick-skipped" or the logic that determines if a sequence is up to date.

Searching the codebase for where "unchanged since archive" / "quick-skipped" is determined so we can tighten the up-to-date check.

The logic is in zip_sequences.py. Let me read the relevant section around line 1152 and the "quick check" that uses dir_mtime vs archive_mtime. The history mentions:
- "Quick check: if directory mtime is older than archive, likely unchanged"
- dir_mtime <= archive_mtime leads to quick-skip

So the issue is: the quick check only uses directory mtime. If the directory's mtime wasn't updated when files inside were changed (e.g. files copied in without touching the folder, or different filesystem behavior), we get a false "unchanged". Making the check "harsher" could mean:
1. Don't do the quick check at all — always compute full state and compare (slower but correct).
2. Or add a stricter condition: e.g. require that the latest file mtime in the directory is also <= archive mtime, or that file count/size matches.

Let me read the actual implementation in zip_sequences.py to see the full flow.

Reading the quick-check logic in `zip_sequences.py`:

I see the flow. The quick check does:
1. If archive exists and stored_state exists
2. Verify all stored files still exist (catches deletions)
3. If dir_mtime <= archive_mtime → quick-skip ("unchanged since archive")

The problem: **directory mtime** is unreliable. On Windows (and sometimes elsewhere), modifying or adding files inside a directory doesn't always update the directory's mtime. So the sequence can have new/updated files but the folder's mtime might still be older than the archive.

To make the check harsher we have two options:
1. **Remove the quick check entirely** — always compute full state and compare. Correct but slower for large trees.
2. **Tighten the quick check** — e.g. don't trust dir_mtime alone; require that we also check the max mtime of files in the directory (or at least one file's mtime). But that would require scanning files anyway, so we might as well do full state.

The cleanest "harsher" approach: **disable the mtime-based quick skip** so we always compute full state and do the real state_changed() comparison. That way we never skip a sequence that has actually changed. We still have the "state-skipped" path when state matches after computing it.

So I'll remove or bypass the quick check: when archive exists and stored_state exists, don't do the dir_mtime <= archive_mtime skip. Still do the "stored files exist" check for the deletion case if we want, but the key is to not skip based on mtime. Actually re-reading the user message: "falsely being detected as up to date" — so we're quick-skipping when we shouldn't. So the fix is to not do the quick skip (or make it much stricter).

Making it "harsher" = don't trust mtime. So: remove the quick-skip branch that uses dir_mtime. We can leave the "stored files exist" check as a fast path for "something was deleted" (if we still want to avoid full state when files were only deleted?), but actually if we remove the quick-skip we always compute state. So the simplest fix is: when archive exists and stored_state exists, don't do the mtime quick-skip — always compute seq_state and run state_changed().

Let me do that: remove the block that does quick_skipped and "Skipping ... (unchanged since archive)" based on dir_mtime. We'll fall through to compute_state and then state_changed.

The issue is clear: the quick check uses **directory mtime** (dir_mtime <= archive_mtime) to skip. On Windows, the directory's mtime often doesn't update when files inside are added or changed, so we get false "unchanged". The fix is to stop trusting that and always do the full state comparison. I'll remove the mtime-based quick-skip so we always compute state and compare with state_changed().
</details></think>

Identifying the cause: the quick-skip uses directory mtime (dir_mtime <= archive_mtime). On Windows, a folder's mtime often doesn't update when files inside are added or modified, causing false "unchanged" skips. Removing the mtime-based quick-skip so we always compute full state and run the real state comparison.
