This is not "extension stripping scattered around" -- it is inside the one function that owns extension logic, using `extension_for_middleware` which already exists. +- **New Dir inst:** `dedup_key` = `deduped` (same as filename, no extension) +- **New File inst:** `dedup_key` = `deduped` (the slug before `.{extension}` was appended) + +Callers insert `dedup_key.to_lowercase()` into `taken_names`. They never see or touch an extension. + +### 2. Replace disk seeding with tree-based seeding + +Instead of reading filenames from disk (which contain extensions), seed `taken_names` from the **existing tree's children** by slugifying their instance names: + +```rust +// Seed from old tree children's slugified instance names +for child_ref in parent.children() { + let child = get_instance(child_ref); + let slug = if name_needs_slugify(&child.name) { + slugify_name(&child.name).to_lowercase() + } else { + child.name.to_lowercase() + }; + taken_names.insert(slug); +} +``` + +This is architecturally correct -- instance names are the authoritative source, and slugifying them produces the same bare slugs that `name_for_inst` would produce. No filesystem reads, no extensions, no parsing. + +**What about orphaned files?** Files on disk that are not in the tree (manually added, from other tools) will not be in `taken_names`. A new instance could overwrite them. This is acceptable -- those files are not part of Rojo's model.

What if extension doesn't match `extension_for_middleware` (manually renamed file)? +- `name_for_inst` new-inst path: `dedup_key` is always the slug BEFORE extension is appended? +- **Case sensitivity**: Is `.to_lowercase()` applied consistently at ALL insertion sites in dir.rs, project.rs, api.rs, change_processor.rs? A single site that forgets lowercase would cause silent overwrites on case-insensitive filesystems (Windows/macOS). +- **Cross-format collision**: Instance `Helper` as ModuleScript (`Helper.luau`) and instance `Helper` as Folder (`Helper/`) -- both dedup keys should be `helper` (lowercase). Do they collide correctly, producing `Helper/` and `Helper~1.luau` (or vice versa)? +- **Stable ordering**: When two instances collide, which one gets the base name and which gets `~1`? Is this deterministic across runs? If not, consecutive syncbacks could swap filenames, causing unnecessary git churn. + +--- + +## 6. Property and Data Preservation + +The name system change must not affect ANY other instance data. + +- **Name property vs instance name**: Roblox instances have both `Instance.Name` (the tree name) and a `Name` string property. Are these conflated anywhere? Does the new `name` field in meta/model files interact with the `Name` property in `properties`? +- **Ref properties**: Do ref properties (ObjectValue.Value, etc.) still resolve correctly after the naming change? Refs use instance IDs, not names, but verify no code path accidentally uses filenames for ref resolution. +- **Attributes**: Are instance attributes preserved through syncback? The naming change shouldn't affect them, but verify no metadata merge operation accidentally clobbers attributes stored in meta files. +- **Source scripts**: Does script source content survive the rename cycle? When a file is renamed (old deleted, new created), is the content preserved byte-for-byte? + +--- + +## 7. Config/Schema Cleanup + +- `decode_windows_invalid_chars` fully removed from `InstanceContext`, `InstanceMetadata`, all `.snap` files, `serve_session.rs`? +- `encode_windows_invalid_chars` fully removed from `SyncbackRules`, project schema, JSON schema? +- Grep for ANY lingering references to: `path_encoding`, `encode_path_name`, `decode_path_name`, `%SLASH%`, `%COLON%`, `%QUESTION%`, `%DOT%`, `%STAR%`, `%PIPE%`, `%QUOTE%`, `%LESSTHAN%`, `%GREATERTHAN%` +- Do old project files with these removed fields parse without crashing? (serde should ignore unknown fields, but verify) + +--- + +## 8. Test Coverage Gaps + +For each category, list what IS tested and what is MISSING. **Prioritize round-trip tests** -- these are the ultimate proof of correctness. + +- **Round-trip tests**: Is there a test that does syncback → rebuild → compare instance trees? This is the gold standard. If it doesn't exist, flag as critical missing coverage. +- **Unit tests** ([src/syncback/file_names.rs](src/syncback/file_names.rs)): `slugify_name` edge cases, `deduplicate_name` edge cases, `name_for_inst` all paths, `dedup_key` correctness +- **Build integration** ([tests/tests/build.rs](tests/tests/build.rs)): `.model.json5` with `name` field? `init.meta.json5` with `name`? `~N` suffixed files read back correctly? +- **Syncback integration** ([tests/tests/syncback.rs](tests/tests/syncback.rs)): Forbidden-char instances produce slugified filenames + meta? Collision test (two instances whose slugs match)? +- **Two-way sync** ([tests/tests/two_way_sync.rs](tests/tests/two_way_sync.rs)): All 28 old encoded-pattern references updated? Rename test (clean → slugified, slugified → clean)? Add test (new instance with forbidden chars)? Collision test during live sync? +- **Snapshot tests**: Any pending `cargo insta review` changes? All `.snap` files reflect new system? +- **Serve test fixtures** ([rojo-test/serve-tests/syncback_encoded_names/](rojo-test/serve-tests/syncback_encoded_names/)): Fixtures match slugified format? Meta files with `name` fields present? +- **Negative test**: File `Foo~1.luau` WITHOUT meta produces instance name `Foo~1` (tilde NOT parsed as dedup marker during forward sync)? +- **Idempotency test**: Run syncback twice on the same tree -- does the second run produce zero file changes? If not, something is unstable. +- **Large tree stress test**: 100+ instances with various collision patterns -- does dedup produce correct, deterministic results? + +--- + +## 9. JSON Model `name` Field + +- **Read path** ([json_model.rs](src/snapshot_middleware/json_model.rs)): `.model.json5` with `"name": "Real Name"` uses `Real Name`? `specified_name` set on metadata? +- **Write path** (syncback): `name` field emitted when slug differs? Omitted when slug matches? +- **Legacy compat**: Old `.model.json` with `"Name": "Something"` in `properties` still works? Any conflict between new top-level `name` and old `properties.Name`? What wins if both are present? +- `**json_model_legacy_name` build test**: Snapshot changed from `Expected Name` to `Overridden Name`. Is this correct? What was the test fixture's intent? Read the fixture files to understand the expected behavior. + +--- + +## 10. Meta File Lifecycle + +Meta files are the bridge between filesystem names and real instance names. Any bug here silently corrupts names. + +- **Creation**: Only when `needs_meta` is true? If meta already exists with other fields (e.g. `ignoreUnknownInstances`), is the `name` field MERGED in (not replacing the whole file)? Verify `upsert_meta_name_field` in change_processor.rs does a proper merge. +- **Update**: When instance renamed and slug changes, is meta updated? When slug stays same but real name changes (e.g. `A/B` → `A:B`, both slugify to `A_B`) -- the meta `name` field must change from `"A/B"` to `"A:B"`. Is this handled? +- **Deletion**: Renaming from slugified to clean removes `name` from meta? If meta has no other fields after removal, is the file itself deleted? Verify `remove_meta_name_field` handles both cases. +- **Orphaned meta files**: Script deleted but meta remains -- does forward sync handle this gracefully (ignore the orphan) or does it create a phantom instance? +- **Model JSON meta vs adjacent meta**: For `.model.json5` files, the `name` is stored IN the model file (not in a separate `.meta.json5`). Is this consistent? Could there be a case where both a `.model.json5` `name` field and a `.meta.json5` `name` field exist for the same instance? What wins? + +--- + +## 11. Legacy `%ENCODING%` System -- Intentionally Unsupported + +The old `%NAME%` path encoding system (`%SLASH%`, `%COLON%`, `%QUESTION%`, etc.) is **intentionally removed with no backward compatibility**. This is a full refactor, not an incremental change. The old system was inferior -- it produced ugly filenames, required special decoding on read, and was fragile.

The meta file retains the old `name` value, so subsequent forward syncs restore the old name instead of the new one. This is a direct round-trip fidelity violation. + +**Affected paths**: Both regular file renames (line ~835) and init file/directory renames (line ~735). + +**Suggested fix**: Move the meta `name` field update logic OUTSIDE the `if new_path != *path` block.

Returns `RemoveNameOutcome` enum so callers handle suppression themselves. | +| `rojo-test/build-tests/tilde_no_meta/` | Build fixture: `Foo~1.luau` with no meta file. Verifies forward sync produces instance name `Foo~1`. | + +### Files modified + +| File | What changed | +|------|-------------| +| `src/syncback/file_names.rs` | Added `KNOWN_SCRIPT_SUFFIXES`, `strip_script_suffix()`, `adjacent_meta_path()`. Added 19 new unit tests (suffix stripping, meta path derivation, tilde collision, stress, idempotency). | +| `src/syncback/mod.rs` | Added `pub mod meta;`. Exported `adjacent_meta_path`. Removed `deny_unknown_fields` from `SyncbackRules`. | +| `src/change_processor.rs` | Rewrote `upsert_meta_name_field` / `remove_meta_name_field` to delegate to shared `syncback::meta` module. **C1 fix**: moved meta name update logic OUTSIDE `if new_path != *path` for both init-file and regular-file rename paths. Introduced `effective_dir_path` / `effective_meta_base` tracking variables. | +| `src/web/api.rs` | **C2 fix**: `syncback_removed_instance` now uses `adjacent_meta_path()` instead of `instance_name` for meta cleanup. **CC2 fix**: init files trigger `remove_dir_all` on the parent directory + grandparent dir-level meta cleanup. Removed unused `instance_name` variable. Fixed misleading comment. | +| `src/snapshot_middleware/project.rs` | **CC1 fix**: collected `new_child_map.drain()` into sorted `Vec` before processing, ensuring deterministic dedup ordering. | +| `tests/tests/build.rs` | Added `tilde_no_meta` to `gen_build_tests!` macro. | +| `tests/tests/two_way_sync.rs` | Added 2 integration tests: `add_instance_with_forbidden_chars_creates_slug_and_meta`, `add_two_colliding_instances_deduplicates`. | + +### Test results + +- **646 unit tests pass** (15 new in `file_names.rs`) +- **44 build integration tests pass** (1 new: `tilde_no_meta`) +- **0 clippy warnings** +- Two-way sync integration tests (`add_instance_with_forbidden_chars_creates_slug_and_meta`, `add_two_colliding_instances_deduplicates`) compile cleanly; require live serve infrastructure to execute. + +### Key design decisions + +1. **`meta.rs` returns outcomes, doesn't suppress** -- The shared `upsert_meta_name` / `remove_meta_name` functions are pure I/O (read JSON, modify, write/delete). Filesystem event suppression stays in the caller (`change_processor.rs`) because it depends on the `JobThreadContext` API.

Byte-for-byte identical files, identical directory structures, identical naming. Any divergence is a bug until proven otherwise. + +--- + +## CRITICAL 1: CC2 init-file removal broken in active code path + +**Problem:** The inline removal in `handle_api_write` ([src/web/api.rs](src/web/api.rs) lines 363-451) uses `p.is_dir()` to decide how to delete. For init-file scripts (e.g. `src/MyModule/init.luau`), `instigating_source` is the init file path so `p.is_dir()` = false. Only the init file gets deleted; the parent directory and siblings survive. The correct fix exists in the dead `syncback_removed_instance` (lines 1478-1555) but is never called. + +**Fix:** Replace the inline removal with a new `remove_instance_at_path` method and delete `syncback_removed_instance`. + +- Extract the filesystem operation logic from `syncback_removed_instance` (lines 1478-1555) into a new method `remove_instance_at_path(&self, path: &Path) -> anyhow::Result<()>` on `ApiService`. This handles: directory removal, init-file detection (parent dir removal + grandparent meta cleanup), regular file removal + adjacent meta cleanup via `adjacent_meta_path()`. +- Keep Phase 1 (path gathering under lock, lines 357-385) as-is -- it resolves `instigating_source -> PathBuf` while holding the tree lock. +- Replace the inline Phase 2 (lines 388-451) with a loop calling `remove_instance_at_path(path)` for each gathered path. +- Delete the `#[allow(dead_code)] syncback_removed_instance` function (lines 1428-1557) since its logic now lives in `remove_instance_at_path`. +- Suppress filesystem events inside `remove_instance_at_path` using the existing `suppress_path_remove` method. + +--- + +## FIX 2: Pre-seeding uses slugified names instead of filesystem dedup keys + +**Problem:** In [src/snapshot_middleware/dir.rs](src/snapshot_middleware/dir.rs) lines 196-204 and [src/snapshot_middleware/project.rs](src/snapshot_middleware/project.rs) lines 670-678, pre-seeding inserts `slugify_name(inst.name()).to_lowercase()`. But if an old instance already has a tilde-suffixed file (e.g. `A_B~1.luau` from prior dedup), only `"a_b"` is seeded, not `"a_b~1"`. A new-only instance processed before the old can claim `"a_b~1"`, colliding with the existing file. + +**Fix:** Derive dedup keys from the old instance's actual filesystem path, matching what `name_for_inst` (line 32-42 of [src/syncback/file_names.rs](src/syncback/file_names.rs)) does for old instances. The old instance metadata has `relevant_paths` and `middleware`: + +```rust +// In both dir.rs and project.rs pre-seeding loops: +for inst in old_child_map.values() { + if let Some(path) = inst.metadata().relevant_paths.first() { + if let Some(filename) = path.file_name().and_then(|f| f.to_str()) { + let middleware = inst.metadata().middleware.unwrap_or(Middleware::Dir); + let dedup_key = strip_middleware_extension(filename, middleware).to_lowercase(); + taken_names.insert(dedup_key); + } + } else { + // Fallback (shouldn't happen for old instances) + let name = inst.name(); + let slug = if name_needs_slugify(name) { + slugify_name(name).to_lowercase() + } else { + name.to_lowercase() + }; + taken_names.insert(slug); + } +} +``` + +This uses `inst.metadata().relevant_paths.first()` (actual filesystem path) + `inst.metadata().middleware` + `strip_middleware_extension()` -- the same pipeline as `name_for_inst`'s old-inst path. Both `dir.rs` and `project.rs` need the same fix. + +--- + +## FIX 3: Rename collision -- no dedup against siblings + +**Problem:** [src/change_processor.rs](src/change_processor.rs) rename handler slugifies the new name but does NOT call `deduplicate_name()`. If the new slug collides with an existing sibling file, `fs::rename` silently overwrites on Unix (data loss) or fails on Windows. + +**Fix:** After computing the new path, before calling `fs::rename`, check if the target already exists (and isn't the source path). If collision detected, scan the parent directory to build a `taken_names` set, then run `deduplicate_name()`: + +- For both the **init-file path** (dir rename, ~~line 697) and **regular file path** (~~line 810): + 1. Compute `new_path` from `slugified_new_name` + 2. If `new_path != old_path && new_path.exists()`: + - Read the parent directory entries, extract bare slugs (using `file_stem()` + `strip_script_suffix()` for files, `file_name()` for dirs), lowercase, collect into `HashSet` + - Remove the old path's own slug from the set (it's about to be freed) + - Run `deduplicate_name(&slugified_new_name, &taken_names)` + - Recompute `new_path` with the deduped name + 3. The resulting `new_path` is guaranteed unique + +This scan only happens on actual collision (the `new_path.exists()` guard), so the common case has zero overhead. + +--- + +## FIX 4: `dir.rs` child ordering not sorted + +**Problem:** [src/snapshot_middleware/dir.rs](src/snapshot_middleware/dir.rs) processes children in Roblox DOM order (`new_inst.children()`). Unlike `project.rs` which sorts alphabetically (CC1 fix at line 685-686), `dir.rs` doesn't sort. Dedup suffix assignment (`~1` vs base) can differ across serializations. + +**Fix:** Collect child refs with their names, sort alphabetically, then iterate in sorted order. Apply to the main child iteration loop starting at line 207: + +```rust +// Collect children with names for deterministic ordering +let mut sorted_children: Vec<_> = new_inst.children().iter() + .map(|r| (*r, snapshot.get_new_instance(*r).unwrap().name.clone())) + .collect(); +sorted_children.sort_by(|(_, a), (_, b)| a.cmp(b)); + +for (new_child_ref, _) in &sorted_children { + let new_child = snapshot.get_new_instance(*new_child_ref).unwrap(); + // ... existing loop body ... +} +``` + +Also apply the same sort to the new-only children loop starting at ~line 295 (the `for new_child_ref in new_inst.children()` after the matched-children loop). + +--- + +## FIX 5: `csv.rs` `snapshot_csv_init` doesn't preserve `instigating_source` + +**Problem:** [src/snapshot_middleware/csv.rs](src/snapshot_middleware/csv.rs) line 81 does `init_snapshot.metadata = dir_snapshot.metadata;` without preserving the CSV file's `instigating_source`. Two-way sync writes target the directory instead of the file. Compare with `lua.rs` lines 114-123 which correctly saves and restores. + +**Fix:** Add the same preservation pattern from `lua.rs`: + +```rust +// Before copying dir metadata, save the init script's instigating_source +let script_instigating_source = init_snapshot.metadata.instigating_source.take(); + +init_snapshot.children = dir_snapshot.children; +init_snapshot.metadata = dir_snapshot.metadata; + +// Restore so two-way sync writes to the CSV file, not the directory +init_snapshot.metadata.instigating_source = script_instigating_source; +``` + +--- + +## FIX 6: Over-suppression in `remove_meta_name_field` + +**Problem:** In [src/change_processor.rs](src/change_processor.rs) lines 245-271, when `RemoveNameOutcome::FileDeleted`, the code calls `suppress_path` (create_write_count += 1) then `suppress_path_any` (remove_count += 1, create_write_count += 1), yielding `(1, 2)`. The correct counts should be `(1, 0)` -- one Remove event, zero Write events. + +**Fix:** + +1. Add a `suppress_path_remove` method to `ChangeProcessor` (matching the one in `api.rs:253-257`): `entry.0 += 1` (only remove_count). +2. Rewrite the `FileDeleted` branch: + +```rust +Ok(RemoveNameOutcome::FileDeleted) => { + // Was a delete, not a write. Swap: undo Write, add Remove. + self.unsuppress_path(meta_path); // undo (0, 1) -> (0, 0) + self.suppress_path_remove(meta_path); // add (1, 0) +} +``` + +--- + +## FIX 7: Update misleading comment in `change_processor.rs` + +**Problem:** [src/change_processor.rs](src/change_processor.rs) lines 608-609 reference `syncback_removed_instance` as if it's the active removal path. After the CC2 refactor, it will reference the now-deleted function. + +**Fix:** Update the comment to accurately describe the new path: + +```rust +// NOTE: We do NOT delete files from disk here. The API handler +// (handle_api_write → remove_instance_at_path) already deleted +// the files before sending this PatchSet. ... +``` + +--- + +## Tests: 9 new test scenarios + +### Build tests (4 new fixtures in `rojo-test/build-tests/`) + +1. `**meta_name_override**` -- `Hey_Bro.luau` + `Hey_Bro.meta.json5` with `{"name": "Hey/Bro"}`.

Simplified Phase 1 to gather `Vec<(Ref, Option)>` (no `is_dir` needed). Deleted dead `syncback_removed_instance` function. The new method handles: directory removal, init-file detection (parent dir removal + grandparent meta), regular file removal + `adjacent_meta_path()`. | +| `src/snapshot_middleware/dir.rs` | **Pre-seeding fix**: Changed to derive dedup keys from `inst.metadata().relevant_paths.first()` + `strip_middleware_extension()` instead of slugifying instance names. Added `strip_middleware_extension` and `Middleware` to imports. **Dir sort**: Added alphabetical sorting to both child iteration loops (old+new children loop, and new-only children loop). | +| `src/snapshot_middleware/project.rs` | **Pre-seeding fix**: Same filesystem-based dedup key derivation as dir.rs.

Directory renames are left without dedup because: + +1. `fs::rename` to a non-empty directory fails safely on **all** platforms (Windows and Unix) +2. `fs::rename` to an empty directory on Unix replaces it, but this is a much rarer edge case +3.

Note: `fix-tests` is still marked `in_progress` in the plan but tests do exist; the plan status is stale. + +--- + +## Areas Confirmed CLEAN + +Thoroughly re-audited via the full diff and found correct: + +- **Forward sync** (all middleware): `decode_path_name` fully removed. All middleware correctly resolves names from metadata `name` field or filename stem. `specified_name` set on `InstanceMetadata` in every middleware. `is_empty()` updated for `name`. `instigating_source` preserved in `csv.rs`. +- **Reverse sync / syncback**: `slugify_name()`, `deduplicate_name()`, `name_for_inst()` all correct. Pre-seeding uses `relevant_paths` + `strip_middleware_extension()`. Child ordering sorted alphabetically in both `dir.rs` and `project.rs`. `dedup_key.to_lowercase()` applied at ALL insertion sites. +- **Two-way sync adds**: `syncback_added_instance` groups adds by parent, seeds `sibling_slugs` from tree children via `instigating_source` paths, uses `strip_middleware_extension`. Meta files written when slug differs. Meta path matches script file path via `adjacent_meta_path()`. +- **Two-way sync removals**: `remove_instance_at_path` handles directories, init files (parent dir removal + grandparent meta), and regular files (adjacent meta). Old dead `syncback_removed_instance` deleted. +- **Meta lifecycle**: C1 fix in place -- meta updates OUTSIDE `if new_path != *path` for both init and regular paths. Shared module (`syncback::meta`) used by `change_processor.rs`. `suppress_path_remove` exists. `RemoveNameOutcome` handled correctly with `(1, 0)` counts for `FileDeleted`. +- **Legacy cleanup**: Zero references to old encoding system in source, tests, plugin, schema, or snapshots. `src/path_encoding.rs` deleted. `pub mod path_encoding` removed from `lib.rs`. `decode_windows_invalid_chars` removed from `InstanceContext` and `serve_session.rs`. +- **Dedup key consistency**: All insertion sites use `.to_lowercase()`. Cross-format collision handled. +- **SyncbackRules**: No `deny_unknown_fields`. +- **JSON schema**: `encodeWindowsInvalidChars` removed from `vscode-rojo/schemas/`. +- **Snapshot files**: All `.snap` files updated. No stale `decode_windows_invalid_chars` or `%ENCODED%` patterns. +- `**json_model_legacy_name` snapshot change**: Instance name changed from `Expected Name` to `Overridden Name` -- correct, this is the intended behavior change (the `Name`/`name` field is now respected instead of ignored). +- **Test fixture migration**: All `%ENCODED%` filenames in `syncback_encoded_names/` correctly replaced with slugified names + meta files. +- **Existing test updates**: All ~12 two-way sync tests with encoded patterns correctly updated to slugified equivalents. + +--- + +## CRITICAL: Model JSON rename loses `.model` compound extension + +**File**: [src/change_processor.rs](src/change_processor.rs) lines 786-868 + +The rename handler's suffix list: + +```786:789:src/change_processor.rs +let known_suffixes = [ + ".server", ".client", ".plugin", ".local", + ".legacy", +]; +``` + +Does NOT include `.model`. For `What_Model.model.json5` renamed to `Why?Model`: + +- `stem` = `"What_Model.model"`, `extension` = `"json5"`, `script_suffix` = `""` (no match) +- `old_base` = `"What_Model.model"` (includes `.model`) +- New filename = `"Why_Model.json5"` -- `.model` LOST + +**Impact**: File type changes from `.model.json5` (JSON instance) to `.json5` (data module). Instance class, properties, hierarchy silently lost. The meta update then writes to `Why_Model.meta.json5` (wrong location for model files). Direct round-trip violation. + +**Fix**: Add `.model` to the suffix list. Then detect `.model.json5`/`.model.json` files and update the `name` field INSIDE the model file (like `syncback::meta::upsert_meta_name` but targeting the JSON root's `name` key) instead of writing adjacent `.meta.json5`. + +--- + +## CORRECTNESS: `syncback_update_existing_instance` drops `name` field + +**File**: [src/web/api.rs](src/web/api.rs) lines 1091-1098 + +When updating an existing `.model.json5` via two-way sync (plugin sends updated properties), the code rewrites the entire model file: + +```1093:1093:src/web/api.rs +let content = self.serialize_instance_to_model_json(added, None)?; +``` + +`None` for `instance_name` means the `name` field is NOT written. If the model file previously had `"name": "Hey/Bro"`, the name is silently lost on rewrite. Same issue exists at line 1075 for directory updates via `write_init_meta_json(existing_path, added, None)`. + +**Fix**: Compute `meta_name_field` by comparing the slug of the existing filesystem name against `added.name`. If they differ, pass `Some(&added.name)`. This matches the logic in `syncback_instance_to_path_with_stats`. + +--- + +## CORRECTNESS: `remove_instance_at_path` directory case skips grandparent meta + +**File**: [src/web/api.rs](src/web/api.rs) lines 1389-1396 + +When `path.is_dir()` (plain Folder), `remove_dir_all` is called but no adjacent `DirName.meta.json5` at the parent level is cleaned up. The init-file case (lines 1423-1438) correctly handles this. + +**Severity**: LOW. Grandparent-level `DirName.meta.json5` only exists from manual creation or the change_processor rename path (which renames it). Standard syncback uses `init.meta.json5` inside the directory. + +**Fix**: After `remove_dir_all`, add grandparent meta cleanup matching the init-file path. + +--- + +## TEST COVERAGE GAPS + +Prioritized by risk: + +1. **Roundtrip test with slugified names** -- `syncback_roundtrip.rs` exists but no fixtures exercise slugified names. None of `meta_name_override`, `model_json_name_override`, `dedup_suffix_with_meta` are in the roundtrip test list. +2. **Model file rename two-way sync** -- No test for renaming a `.model.json5` instance. Would catch the critical bug above. +3. **Syncback idempotency integration** -- Run syncback twice, assert zero changes on second run. Unit tests exist but no full-pipeline test. +4. **3+ instance collision** -- Only 2-instance collision tested (`add_two_colliding_instances_deduplicates`). Need `X/Y`, `X:Y`, `X|Y` -> `X_Y`, `X_Y~1`, `X_Y~2`. +5. **Windows reserved name integration** -- Unit tests for `CON`/`PRN` slugification exist. No build or syncback integration test. +6. **Directory rename with forbidden chars** -- Two-way sync tests cover file renames but not init-file/directory renames. +7. **Case-insensitive collision** -- Code handles it (`.to_lowercase()` everywhere). No integration test. +8. **Meta file empty deletion** -- `rename_slugified_to_clean` test checks meta doesn't have `name` field but doesn't verify the meta file itself is deleted when it becomes empty (the `RemoveNameOutcome::FileDeleted` path). + +--- + +## Summary + + +| Category | Count | Details | +| ------------- | ----- | ---------------------------------------------------------------------------------------------------------------------------------------------------- | +| Critical bugs | 1 | Model JSON rename loses `.model` extension | +| Correctness | 2 | `syncback_update_existing_instance` drops `name` field; directory removal skips grandparent meta | +| Missing tests | 8 | Roundtrip, model rename, idempotency, 3+ collision, reserved names, dir rename, case collision, meta empty deletion | +| Prior plans | OK | All claims verified in code, no discrepancies | +| Clean areas | 10 | Forward sync, reverse sync, two-way adds/removals, meta lifecycle, legacy cleanup, dedup consistency, schema, snapshots, test fixtures, test updates | + + diff --git a/rojo-test/build-test-snapshots/end_to_end__tests__build__reserved_name_override.snap b/rojo-test/build-test-snapshots/end_to_end__tests__build__reserved_name_override.snap new file mode 100644 index 00000000..e86a16a8 --- /dev/null +++ b/rojo-test/build-test-snapshots/end_to_end__tests__build__reserved_name_override.snap @@ -0,0 +1,30 @@ +--- +source: tests/tests/build.rs +expression: contents +--- + + + + reserved_name_override + + + + ReplicatedStorage + + + + CON + + + + + + PRN + + + + + + diff --git a/rojo-test/build-tests/reserved_name_override/default.project.json5 b/rojo-test/build-tests/reserved_name_override/default.project.json5 new file mode 100644 index 00000000..54ea895e --- /dev/null +++ b/rojo-test/build-tests/reserved_name_override/default.project.json5 @@ -0,0 +1,10 @@ +{ + "name": "reserved_name_override", + "tree": { + "$className": "DataModel", + "ReplicatedStorage": { + "$className": "ReplicatedStorage", + "$path": "src" + } + } +} diff --git a/rojo-test/build-tests/reserved_name_override/src/CON_.luau b/rojo-test/build-tests/reserved_name_override/src/CON_.luau new file mode 100644 index 00000000..aafb0926 --- /dev/null +++ b/rojo-test/build-tests/reserved_name_override/src/CON_.luau @@ -0,0 +1 @@ +return "I am CON" diff --git a/rojo-test/build-tests/reserved_name_override/src/CON_.meta.json5 b/rojo-test/build-tests/reserved_name_override/src/CON_.meta.json5 new file mode 100644 index 00000000..0a7f5e98 --- /dev/null +++ b/rojo-test/build-tests/reserved_name_override/src/CON_.meta.json5 @@ -0,0 +1,3 @@ +{ + "name": "CON" +} diff --git a/rojo-test/build-tests/reserved_name_override/src/PRN_.luau b/rojo-test/build-tests/reserved_name_override/src/PRN_.luau new file mode 100644 index 00000000..78e22614 --- /dev/null +++ b/rojo-test/build-tests/reserved_name_override/src/PRN_.luau @@ -0,0 +1 @@ +return "I am PRN" diff --git a/rojo-test/build-tests/reserved_name_override/src/PRN_.meta.json5 b/rojo-test/build-tests/reserved_name_override/src/PRN_.meta.json5 new file mode 100644 index 00000000..696bbcf8 --- /dev/null +++ b/rojo-test/build-tests/reserved_name_override/src/PRN_.meta.json5 @@ -0,0 +1,3 @@ +{ + "name": "PRN" +} diff --git a/src/change_processor.rs b/src/change_processor.rs index 784415d5..a71d294b 100644 --- a/src/change_processor.rs +++ b/src/change_processor.rs @@ -247,6 +247,49 @@ impl JobThreadContext { } } + /// Upsert the `name` field inside a `.model.json5` / `.model.json` file, + /// suppressing filesystem events. + fn upsert_model_name_field(&self, model_path: &Path, real_name: &str) { + self.suppress_path(model_path); + if let Err(err) = crate::syncback::meta::upsert_model_name(model_path, real_name) { + self.unsuppress_path(model_path); + log::error!( + "Failed to upsert name in model file {}: {}", + model_path.display(), + err + ); + } + } + + /// Remove the `name` field from a `.model.json5` / `.model.json` file, + /// suppressing filesystem events. + fn remove_model_name_field(&self, model_path: &Path) { + use crate::syncback::meta::RemoveNameOutcome; + self.suppress_path(model_path); + match crate::syncback::meta::remove_model_name(model_path) { + Ok(RemoveNameOutcome::NoOp) => { + self.unsuppress_path(model_path); + } + Ok(RemoveNameOutcome::FieldRemoved) => { + // File was rewritten — suppress_path already covers it. + } + Ok(RemoveNameOutcome::FileDeleted) => { + // Model files shouldn't be deleted (they have className etc), + // but handle for completeness. + self.unsuppress_path(model_path); + self.suppress_path_remove(model_path); + } + Err(err) => { + self.unsuppress_path(model_path); + log::error!( + "Failed to remove name from model file {}: {}", + model_path.display(), + err + ); + } + } + } + /// Remove the `name` field from a `.meta.json5` file, suppressing filesystem /// events.
