fix(filestation): per-path serial for multi-path getinfo and delete by cmeans-claude-dev[bot] · Pull Request #77 · cmeans/mcp-synology

cmeans-claude-dev · 2026-05-01T03:30:43Z

Summary

Closes #68 (both halves). DSM 7.x's SYNO.FileStation.List getinfo and SYNO.FileStation.Delete start do not honor the documented comma-joined multi-path format — even on v2. A request with path=/a,/b is treated as a single literal path. For getinfo this surfaces as one synthetic record whose path field IS the literal comma-joined string (the handler's len(files) == 1 branch then renders it as a single info card). For delete_files it surfaces as a successful task that no-ops on every input, returning [+] Deleted N item(s) with all paths listed but none removed.

Fix: per-path serial calls. Both tools iterate paths and issue one DSM request per input path; results aggregate into the same response shape callers already expect (single info card for one path, table for multiple; per-share recycle-bin messaging unchanged for delete). Matches the user's documented workaround on #68. Trade-off: N round-trips for N paths, fine for typical small-N usage.

Round-1 → round-2 history

Round 1 hypothesized v3-vs-v2 misinterpretation and shipped a one-line v2 pin on getinfo. The newly-strengthened vdsm assertion (test_get_file_info_multiple_paths against DSM 7.2.2) failed in CI on the round-1 head:

AssertionError: v2 pin regression: response contains the comma-joined path string,
indicating DSM treated the input as a single literal path.
Got: 'File Info: /testshare,/writable\n========\n  Name:  \n  Path:  /testshare,/writable\n  Type:  File\n  Size:  0 B'

That output is exactly the bug shape #68 reports — and it reproduced even on v2. So the real bug isn't a version-pin miss; DSM 7.x just doesn't accept comma-joined multi-path on these methods. Round 2 (commit ddfac45) pivoted to per-path serial in both get_file_info and delete_files. Round-2 follow-up commit 4a3e695 added defensive empty-paths guards (Codecov was flagging the new branches); commit dd7c30e updated this PR's CHANGELOG test counts after that.

Diff at a glance

```python

Before — get_file_info

normalized = [normalize_path(p) for p in paths]
path_param = escape_multi_path(normalized)
data = await client.request(
"SYNO.FileStation.List", "getinfo",
params={"path": path_param, ...},
)
files = data.get("files", [])

After — get_file_info

normalized = [normalize_path(p) for p in paths]
files: list[dict[str, Any]] = []
for p in normalized:
data = await client.request(
"SYNO.FileStation.List", "getinfo",
version=getinfo_version,
params={"path": p, ...},
)
files.extend(data.get("files", []))
```

delete_files got the same treatment via an extracted _delete_one_path helper that owns the start → poll → stop async-task pattern; delete_files becomes a thin loop over normalized paths plus the existing recycle-bin messaging.

What stays from round 1

The v2 pin on getinfo itself remains (now defensive parallelism with Delete/CopyMove/Search rather than the bug fix it claimed to be in round 1).
tests/conftest.py SYNO.FileStation.List max_version=3 bump stays (matches DSM 7.x reality; protects future tests from being fooled by a max-resolves-to-2 default).
TestMultiPathDelete integration test (now re-exported on vdsm too).

Acceptance criteria

get_file_info returns one record per input path on real DSM 7.x.
delete_files actually deletes every path in a multi-path call on real DSM 7.x.
Per-share recycle-bin messaging on delete_files unchanged from fix(filestation): probe recycle-bin status per share #73.
Defensive empty-paths guard returns a precise not_found error on paths=[].

- Verify regression-detect on the new wire test: temporarily change metadata.py back to a single multi-path call (path=escape_multi_path(normalized)), run test_multipath_uses_per_path_serial_calls. It should fail with expected two DSM calls (one per path), got 1. Restore.
- Optionally: run the TestMultiPathDelete integration test against a real NAS to confirm multi-path delete actually deletes (requires tests/integration_config.yaml with a writable_folder). vdsm has it covered automatically via the re-export.

🤖 Generated with Claude Code

Partial fix for #68 (the get_file_info half). modules/filestation/metadata.py:58 called SYNO.FileStation.List getinfo without specifying a version. On real DSM 7.x (which advertises v3 of FileStation.List) the request fell through to v3, which silently misinterprets the v2-style comma-joined `path` query param as a single literal path. DSM returned ONE synthetic record with that bogus path, and the handler's `len(files) == 1` branch rendered it as a single info card — even though the caller asked about multiple paths. Pin getinfo to v2 using the same negotiate_version(..., max_version=2) pattern Delete/CopyMove/Search already use. getinfo was missed when that sweep was done. Strong regression coverage: - tests/conftest.py: bump SYNO.FileStation.List max_version from 2 to 3 to match DSM 7.x reality. Without this bump, a regression that reverts the v2 pin would still send version=2 (default resolved to max_version=2) and the test would silently pass. - tests/modules/filestation/test_metadata.py::TestGetFileInfo:: test_request_pinned_to_v2: respx-captured request asserts api/method/version/path on the wire. Catches the regression even with v3 advertised. Also added tests/test_integration.py::TestMultiPathDelete (creates two folders, deletes in one multi-path call, verifies via list_files that BOTH are gone). For real-NAS / vdsm runs. The delete_files half of #68 is undiagnosed locally — Delete IS already pinned to v2, respx-level wire-dump shows correct comma-joined path, and the existing unit test passes. The bug only manifests on the user's actual DSM 7.1.1. Debug-level logs on a reproducer are the next step. #68 stays open until that's resolved.

Codecov Report

✅ All modified and coverable lines are covered by tests.

📢 Thoughts on this report? Let us know!

Closes #68 (both halves). vdsm CI on DSM 7.2.2 disproved the round-1 v2-pin hypothesis: the comma-joined path is mis-parsed by DSM as a single literal path even on v2 (proven by the new test_get_file_info_multiple_paths assertion failing in CI with `Path: /testshare,/writable`). Real fix matches the user's documented workaround: one DSM call per input path. Both get_file_info and delete_files now iterate paths and issue per-path requests, aggregating into the same response shape callers already expect. Refactor: - modules/filestation/metadata.py: get_file_info loops client.request for each path, accumulates `files[]`, renders single-info card for one result and table for multiple. - modules/filestation/operations.py: extracted _delete_one_path with the start → poll → stop async-task pattern; delete_files iterates paths and calls it. Per-share recycle-bin messaging unchanged. Tests: - tests/modules/filestation/test_metadata.py: replaced test_request_pinned_to_v2 with test_multipath_uses_per_path_serial_calls asserting N requests for N paths, each carrying a single path with no commas, all pinned to v2. - tests/vdsm/test_vdsm_integration.py: re-export TestMultiPathDelete so the new vdsm regression test runs in CI. Trade-off: N round-trips for N paths. Acceptable for typical small-N usage. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Course correction — round-1 root cause was wrong; ship per-path serial instead

vdsm CI on the round-1 PR (v2 pin on getinfo) just disproved the v2-pin hypothesis. The new vdsm assertion I added (test_get_file_info_multiple_paths on the same PR) failed on DSM 7.2.2:

```
AssertionError: v2 pin regression: response contains the comma-joined path string,
indicating DSM treated the input as a single literal path.
Got: 'File Info: /testshare,/writable\n========\n Name: \n Path: /testshare,/writable\n Type: File\n Size: 0 B'
```

DSM treated path=/testshare,/writable as one literal path even on v2 — exactly the symptom #68 reports. So the real bug isn't a version-pinning miss; it's that DSM 7.x's SYNO.FileStation.List getinfo (and SYNO.FileStation.Delete start) do not honor the documented comma-joined multi-path format at all.

Same vdsm pattern almost certainly explains the delete_files half too — the user's documented workaround on #68 was already "loop one path at a time," which is exactly what works. So I'm now fixing both halves in this PR with the same mechanism: per-path serial calls.

What changed (commit `ddfac45`)

modules/filestation/metadata.py::get_file_info — loops client.request for each input path; accumulates files[]; renders single-info card for one result, table for multiple. Per-path latency is one DSM round-trip.
modules/filestation/operations.py — extracted _delete_one_path with the start → poll → stop async-task pattern; delete_files iterates paths and calls it. Per-share recycle-bin messaging unchanged.
tests/modules/filestation/test_metadata.py — replaced the now-obsolete test_request_pinned_to_v2 with test_multipath_uses_per_path_serial_calls. Asserts N requests for N paths, each carrying a single path with no commas, all pinned to v2, results aggregate correctly.
tests/vdsm/test_vdsm_integration.py — re-export TestMultiPathDelete so the new multi-path delete regression test runs on vdsm too. Without this, vdsm wouldn't have caught the original delete bug; with it, it would have.

What stays from round 1

The v2 pin on getinfo itself remains (now defensive parallelism with Delete/CopyMove/Search rather than the bug fix it claimed to be in round 1).
The tests/conftest.py SYNO.FileStation.List max_version=3 bump stays (matches DSM 7.x reality; protects future tests from being fooled by a max-resolves-to-2 default).
The TestMultiPathDelete integration test stays (now also re-exported on vdsm).

Trade-off

N round-trips for N paths. Multi-path delete on 12 paths now does 12 start → poll → stop cycles serially — a few seconds slower than the (broken) batch call. Acceptable for typical small-N usage; matches the user's existing workaround.

Title updated; PR body's "What's NOT in this PR" section is now stale (the delete half IS in this PR). I'll update the body too if QA finds it useful.

Codecov on PR #77 flagged 2 missing patch lines: the `if not paths: error_response(...)` guard added to both get_file_info and delete_files in the per-path serial refactor. Without input, the per-path loop would silently no-op and either return an empty success message (delete) or fall through to a less precise "no file information returned" not_found (get_file_info). The guard short-circuits to a precise "No paths provided" not_found before any DSM call. Adds two regression tests asserting the guard fires with the expected error envelope (code, message, param, value). Patch coverage on the PR diff now 100%.

QA Round 1 — Two findings, both doc

The actual fix is solid. Round-1 hypothesis (pin getinfo to v2) was correctly disproven by vdsm CI on DSM 7.2.2; round-2 pivoted to per-path serial in both get_file_info and delete_files, matching the user's documented workaround on #68. The _delete_one_path extraction is clean, the empty-paths defensive guards are good additions, and the new wire-level test (test_multipath_uses_per_path_serial_calls) catches the right regression class. TestMultiPathDelete integration coverage re-exported to vdsm correctly. CHANGELOG entry and Dev's follow-up comment on #68 both accurately describe the per-path-serial approach.

Findings

ID	Finding
F1 (substantive)	PR body is from round 1; the code is round 2. The PR body still describes the v2-pin-only approach with `delete_files` punted to a future PR — but the actual code, the CHANGELOG entry, and Dev's own 2026-05-01 03:42:56Z comment on issue #68 ("Update — both halves now addressed in PR #77") all correctly reflect the per-path-serial fix for both halves of #68. Specific stale parts of the PR body: (a) Summary opens "Partial fix for #68 — the `get_file_info` half." — both halves are fixed; (b) "Root cause" and "Diff" sections describe and show only the v2-pin one-line change — actual approach is the per-path serial loop; (c) "What's NOT in this PR: The `delete_files` half of #68 remains undiagnosed." — it's diagnosed and fixed; (d) "Bonus" framing on `TestMultiPathDelete` — it's no longer a bonus, it's the regression test for one of the actual fixes in this PR; (e) Manual test #2 references `tests/modules/filestation/test_metadata.py::TestGetFileInfo::test_request_pinned_to_v2`, which does not exist — the round-2 rename is `test_multipath_uses_per_path_serial_calls`; (f) Manual test #8's verification recipe describes how to test the v2-pin approach, not per-path serial; (g) "Verification I already ran" reports 548 passed — actual is 550. Per the project's doc-drift-is-substantive rule, blocking. Full rewrite of the PR body to match the round-2 implementation. The CHANGELOG entry is already a strong template for the rewrite.
F2 (substantive — minor)	CHANGELOG count drift. The CHANGELOG entry near the end reads `548 unit tests pass at 96.05% coverage`. My local run on `4a3e695` shows 550 passed at 96.13%. The +2 empty-paths defensive-guard tests added in commit `4a3e695` ("test(filestation): cover empty-paths defensive guard") didn't trigger a CHANGELOG amendment — that commit changed test counts but not the prose that quotes them. Update to `550 unit tests pass at 96.13% coverage`, or drop the specific number to make the entry resilient to future test additions on the same branch. Per the project's strict CHANGELOG-per-PR discipline, the round-2 commits should have included this amendment.

Note (not a finding)

Held off on flipping the PR-body manual-test checkboxes because items #2 and #8 reference an approach and a test name that don't exist post-round-2. Will check them in round 2 once the body is rewritten — the tests themselves all pass, and the only reason boxes are still empty is the stale body.

Verdict

QA Failed Round 1. Both findings are documentation fixes; the code itself is in a clean place. Round 2 should be a single PR-body rewrite + a one-line CHANGELOG count tweak.

Applying QA Failed as the final act of round 1. Both findings are doc fixes: F1 is a comprehensive PR-body rewrite to match the round-2 per-path-serial approach (the code, CHANGELOG, and #68 comment thread are all current — only the PR body is stale).

Round 2 — F1 + F2 addressed (doc-only fixes)

F1 — PR body rewrite

Full rewrite of the PR body to match the round-2 per-path-serial implementation. Specifically resolves all seven sub-points QA flagged:

(a) Summary now opens with "Closes v0.5.0 regression: delete_files and get_file_info silently mishandle multi-path arrays #68 (both halves)" — no more "partial fix".
(b) Root cause + Diff now describe DSM 7.x's refusal to honor comma-joined multi-path and show the before/after of the per-path serial loop (no more v2-pin one-liner).
(c) "What's NOT in this PR" section deleted — both halves are in the PR.
(d) "Bonus" framing on TestMultiPathDelete removed — it's now part of "What stays from round 1" as the regression test for one of the actual fixes here.
(e) Manual test Add PR label automation and QA gate workflows #2 now references test_multipath_uses_per_path_serial_calls (the real round-2 name).
(f) Manual test Add Glama score badge to README #8 verification recipe rewritten to test the per-path serial fix (revert to single multi-path call, run wire test, expect failure of "expected two DSM calls (one per path), got 1").
(g) Verification table updated to 550 passed, 96.13% coverage.

Also added a "Round-1 → round-2 history" section so future readers can trace the v2-pin → per-path-serial pivot without needing to read the comment thread, and an "Acceptance criteria" section anchored on the user-visible behaviors closed by the PR.

F2 — CHANGELOG count

Commit dd7c30e updates the CHANGELOG entry's trailing test-count from 548 unit tests pass at 96.05% coverage → 550 unit tests pass at 96.13% coverage to match the head after the round-2 empty-paths-guard tests landed. Kept the specific number per the project's convention (other entries cite counts too) rather than dropping it as the alternative QA suggested.

No code changes this round

Both findings were doc-only. The code on the branch is unchanged from the round-2 head (4a3e695) other than the CHANGELOG amendment in dd7c30e. CI on the new head should match — 13/13 green, vdsm SUCCESS.

Ready for round 2.

cmeans

QA Round 2 — PASS

Both round-1 findings closed.

F1 — PR body rewrite

Comprehensive rewrite. Summary now opens **Closes #68 (both halves).** and accurately describes the per-path-serial fix. New "Round-1 → round-2 history" section preserves the disproven v2-pin hypothesis as part of the audit trail and quotes the actual vdsm CI failure that drove the pivot — useful for future readers wondering why the pin is still there. The "Diff at a glance" snippet now shows the per-path serial loop (not the v2-pin one-liner), and "What stays from round 1" cleanly separates the still-relevant pieces (defensive v2 pin, conftest max_version=3 bump, TestMultiPathDelete) from the abandoned hypothesis. Acceptance criteria restructured to match the actual fix.

Manual-test section is fully reworked:

#2 now references the correct test name test_multipath_uses_per_path_serial_calls (round-1 referenced the nonexistent test_request_pinned_to_v2).
#3 is new: covers both empty-paths defensive guards.
#7 is a thoughtful new structural-correctness check (escape_multi_path no longer imported in metadata.py).
#8's regression-detect recipe is now accurate for the per-path-serial approach (revert metadata.py to escape_multi_path-style, expect "expected two DSM calls, got 1").
#9 acknowledges that vdsm covers TestMultiPathDelete automatically via the re-export.

F2 — CHANGELOG count tweak

dd7c30e flipped 548 unit tests pass at 96.05% coverage → 550 unit tests pass at 96.13% coverage. Single-line fix exactly as recommended.

## Summary Patch release rolling up the post-0.5.0 fixes. Five PRs land in this release: - **#69** — Atomic state-file writes (closes #36). New `core/fs.py::atomic_write_text` helper; `save_state` and `_save_global_state` route through it. Eliminates torn-write windows on `state.yaml` / `global.yaml`. - **#71** — Atomic write for `cli/setup.py` interactive config (closes #70). Last user-visible non-atomic write site cascaded onto the same helper. - **#72** — README per-installer and per-OS download-breakdown badges. Mirrors mcp-clipboard's layout; all 9 new badges link to `cmeans/pypi-winnow-downloads` (the dogfooded service). - **#73** — Recycle-bin status probed per share (closes #37). Lazy `ensure_recycle_status` helper; self-correct on observation; clear-on-reauth via new `AuthManager.add_on_reauth_callback` API. Fixes incorrect "Recycle bin is enabled" messaging on shares with `#recycle` disabled. - **#77** — Per-path serial for multi-path `getinfo` and `delete` (closes #68). **Critical: fixes a v0.5.0 silent-no-op regression on `delete_files` with multi-path arrays** — caller would see `[+] Deleted N item(s)` listing every path, but none were actually deleted on real DSM 7.x. Same root cause on `get_file_info` (single synthetic record with comma-joined `path`). Both tools now issue one DSM call per input path. ## Files touched (per CLAUDE.md release procedure) - `pyproject.toml`: 0.5.0 → 0.5.1 - `server.json`: synced via `scripts/sync-server-json.py` (top-level + `packages[0].version`) - `uv.lock`: refreshed via `uv lock` - `CHANGELOG.md`: `## Unreleased` renamed to `## 0.5.1 (2026-05-01)`; fresh empty `## Unreleased` added above for the next cycle ## QA ### Manual tests 1. - [x] `python scripts/sync-server-json.py --check` — reports "in sync (0.5.1)". 2. - [x] `uv run pytest` — 550 passed, 96.13% coverage. 3. - [x] `uv run ruff check src/ tests/ scripts/` — clean. 4. - [x] `uv run ruff format --check src/ tests/ scripts/` — clean. 5. - [x] `uv run mypy src/ scripts/` — clean. 6. - [x] CHANGELOG diff is exactly: `## Unreleased` → `## 0.5.1 (2026-05-01)`, plus a fresh empty `## Unreleased` heading inserted above.

Closes #84. Same root-cause family as #68 (delete + getinfo). DSM 7.x's `SYNO.FileStation.CopyMove start` does not honor the documented comma-joined multi-path format on v2 — a request with `path=/a,/b` is treated as a single literal path and silently no-ops while the task reports success. Symptom on `move_files(paths=[a, b])`: tool returns `Moved 2 item(s) ... Source files have been removed.` while no files actually move on disk; same shape on `copy_files`. Single-path moves worked in v0.5.1 because the comma-join is never constructed for a one-element list. The multi-path code path was never exercised by an integration test that asserted BOTH source and destination state, so the silent-no-op slipped through. Fix matches PR #77's approach for delete: extract `_copy_move_one_path` and iterate, issuing one DSM CopyMove task per input path inside `_copy_move`. `escape_multi_path` is no longer called there. `restore_from_recycle_bin` routes through `_copy_move` for its multi-path branch, so it inherits the fix automatically. Tests (4 new unit + 6 new integration; 1 strengthened): Unit: - TestCopyFiles::test_multipath_uses_per_path_serial_calls — N CopyMove start requests for N paths, each with a single path (no commas), all pinned to v2, results aggregate correctly. - TestMoveFiles::test_multipath_uses_per_path_serial_calls — same shape with remove_src=true asserted per-call. - test_copy_empty_paths_returns_not_found and test_move_empty_paths_returns_not_found — defensive guard added with the per-path refactor. Integration (also re-exported in tests/vdsm/test_vdsm_integration.py): - TestMultiPathMove (3 cases) — creates two folders, multi-path move, asserts both at dest AND both gone from source. - TestMultiPathCopy (3 cases) — same shape but asserts both at dest AND both still at source (the copy invariant). Strengthened: - TestWriteOperations::test_07_verify_move — previously-soft "should not be in this listing" comment converted to a hard `assert "original/" not in src_listing` so silent-no-op moves can't slip past dest-only checks. 558 unit tests pass at 96.18% coverage. ruff/mypy clean.

## Summary Closes #84. Same root-cause family as #68 (delete + getinfo). DSM 7.x's `SYNO.FileStation.CopyMove start` does **not** honor the documented comma-joined multi-path format on v2 — a request with `path=/a,/b` is treated as a single literal path and silently no-ops while the task reports success. Symptom on `move_files(paths=[a, b])`: tool returns `Moved 2 item(s) ... Source files have been removed.` while no files actually move on disk. Same shape on `copy_files`. Single-path moves worked in v0.5.1 because the comma-join is never constructed for a one-element list. The multi-path code path was never exercised by an integration test that asserted *both* source and destination state, so the silent-no-op slipped past the existing dest-only check. ## Why this slipped through (and what changed in coverage) - No multi-path move or copy integration test existed. `test_06_move_folder` did one single-path call; the post-#68 `TestMultiPathDelete` was added for delete only. - `test_07_verify_move` only asserted the file appeared at the destination — the source-side check was a comment, not an assertion. A silent no-op that returned a success string would have passed. This PR adds the missing multi-path tests for both move and copy and strengthens the single-path test to also assert source-side state. Going forward, any state-mutating integration test should follow the source-AND-dest pattern so silent-no-op regressions can't return. ## What changed - **Code:** Extracted `_copy_move_one_path` (mirroring `_delete_one_path` from #77) and wrapped `_copy_move` in a per-path loop. `escape_multi_path` is no longer called there. `restore_from_recycle_bin` routes through `_copy_move` for its multi-path branch, so it inherits the fix automatically. Added a defensive empty-list guard at the top of `_copy_move` so an empty `paths` list short-circuits with a clear error instead of returning a misleading "0 item(s)" success message. - **Pinned to v2** kept — same DSM v3 JSON-format issue as #77. - **Aggregated `processed_size`** across per-path tasks so the response keeps reporting the total byte count. ## Tests **Unit (4 new):** - `TestCopyFiles::test_multipath_uses_per_path_serial_calls` — N CopyMove `start` requests for N paths, each carrying a single path (no commas), all pinned to v2, aggregated response covers every input file. - `TestMoveFiles::test_multipath_uses_per_path_serial_calls` — same shape with `remove_src=true` asserted per-call. - `test_copy_empty_paths_returns_not_found` / `test_move_empty_paths_returns_not_found` — defensive guard added with the refactor. **Integration (6 new, also re-exported in `tests/vdsm/test_vdsm_integration.py`):** - `TestMultiPathMove` (3 cases): create two folders → multi-path move → assert BOTH at dest AND both gone from source. - `TestMultiPathCopy` (3 cases): same shape but assert BOTH at dest AND both still at source (the copy invariant). **Strengthened (1):** - `TestWriteOperations::test_07_verify_move` — previously-soft "should not be in this listing" comment converted to `assert "original/" not in src_listing` so silent-no-op moves can't slip past dest-only checks. 581 unit tests pass at 96.19% coverage on the rebased branch (post-#83 merge into main). ruff/mypy clean. ## Test plan - [x] `uv run pytest tests/modules/filestation/test_operations.py -v` — 33 pass (was 29) - [x] `uv run pytest` — full unit suite green (581 passed, 112 deselected, 96.19%) - [x] `uv run ruff check src/ tests/` - [x] `uv run ruff format --check src/ tests/` - [x] `uv run mypy src/` - [x] vdsm CI runs `TestMultiPathMove` + `TestMultiPathCopy` against DSM 7.2.2 and they pass - [ ] Smoke against real NAS (post-merge): two-file `move_files` actually moves both files; `get_file_info` confirms files at dest with non-zero size and absent at source 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: cmeans-claude-dev[bot] <272174644+cmeans-claude-dev[bot]@users.noreply.github.com> Co-authored-by: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

## Summary Closes #42. The "Version pinning" bullet under `## Key Conventions → DSM API Client` previously named only CopyMove, Delete, and Search as v2-pinned. Audit of `src/` (`grep -rn "max_version=2\|min(.*max_version, 2)"`) found two more pins the bullet didn't mention: - **`SYNO.FileStation.Upload`** (`src/mcp_synology/core/client.py:354`, inside `upload_file`) — Upload is a special-case multipart POST not routed through `request()`, so its v2 pin lives in the upload code path with `min(info.max_version, 2)`. v3 advertises a JSON body the multipart code can't speak. - **`SYNO.FileStation.List getinfo`** (`src/mcp_synology/modules/filestation/metadata.py:80`) — added by PR #77 to dodge the v3 multipath quirk that surfaced as #68. The bullet now lists all five APIs with file pointers and the rationale: *"removing any of these pins reintroduces silent failures on DSM 7.x — the v3 request format DSM advertises is metadata, not a mandate."* A future refactor can't innocently strip a pin and rediscover the bug. ## Audit verification ``` $ grep -rn "max_version=2\|min(.*max_version, 2)" src/ src/mcp_synology/modules/filestation/search.py:78: search_version = min(2, client.negotiate_version("SYNO.FileStation.Search", max_version=2)) src/mcp_synology/modules/filestation/metadata.py:80: getinfo_version = min(2, client.negotiate_version("SYNO.FileStation.List", max_version=2)) src/mcp_synology/modules/filestation/operations.py:309: copymove_version = min(2, client.negotiate_version("SYNO.FileStation.CopyMove", max_version=2)) src/mcp_synology/modules/filestation/operations.py:467: delete_version = min(2, client.negotiate_version("SYNO.FileStation.Delete", max_version=2)) src/mcp_synology/core/client.py:354: resolved_version = version if version is not None else min(info.max_version, 2) ``` 5 pins → 5 mentions in the convention. No undocumented pins remain. ## Files changed - `CLAUDE.md` — single bullet rewritten under `## Key Conventions → DSM API Client` - `CHANGELOG.md` — `### Changed` entry under `## Unreleased` ## Test plan - [x] CI green - [x] `grep -c "Upload\|List getinfo" CLAUDE.md` returns ≥1 - [x] No code change, so functional smoke not needed 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: cmeans-claude-dev[bot] <272174644+cmeans-claude-dev[bot]@users.noreply.github.com> Co-authored-by: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

## Summary - Closes **#95**: `create_folder` silently mangled multi-path arrays in v0.5.2 — DSM received `name=a,b` / `folder_path=/X,/X` as single literals and created one mangled folder while the tool reported `Created 1 folder(s)`. - Same root-cause family as #68 (delete + getinfo, fixed in #77) and #84 (move/copy, fixed in #85). `create_folder` was the last unfixed write tool in the family — missed when the broader array-flattening fix landed because there was no multipath unit test for it. - Fix matches the established per-path serial pattern: one DSM `CreateFolder` call per input path, aggregating `folders[]` from each response. `escape_multi_path` is no longer called there. - Adds `TestCreateFolder::test_multipath_uses_per_path_serial_calls` asserting (a) N create requests for N paths, (b) each request carries a single bare `name` and a single `folder_path` parent (no commas), and (c) the aggregated response names every input folder. The unit-test gap that let #95 ship is closed. - Files **#96** as the systematic test-coverage follow-up: per-path-serial multipath tests + vdsm coverage for every File Station write tool, so the fifth instance of this regression class can be caught in CI rather than in live usage. ## Test plan - [x] `uv run pytest -q` — 600 passed, 96.25% coverage (was 599 / 96.25%) - [x] `uv run ruff check src/ tests/` — clean - [x] `uv run ruff format --check src/ tests/` — clean - [x] `uv run mypy src/` — clean - [x] New multipath test fails on the pre-fix code (verified during TDD: `expected two CreateFolder calls (one per path), got 1` with `folder_path='/video/Show,/video/Show'`) - [ ] vdsm integration smoke (deferred — adds a dedicated multipath vdsm test for `create_folder` is part of #96) ## Notable The fix removes the now-unused `escape_multi_path` import from `operations.py` since no remaining function in that file calls it. The helper itself stays in `helpers.py` (still legitimate for any caller that needs path-as-form-param escaping that doesn't traffic in the array-flattening shape). 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: cmeans-claude-dev[bot] <272174644+cmeans-claude-dev[bot]@users.noreply.github.com> Co-authored-by: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
