+# miroir-zc2.5: Dump Import Compatibility Matrix Verification
+
+## Task Summary
+
+P12.OP5: Enumerate dump import variants that streaming mode cannot handle.
+
+## Work Completed
+
+### 1. Fixed Enhancement Bead References
+
+The compatibility matrix at `docs/dump-import/compatibility-matrix.md` incorrectly referenced non-existent or misnamed enhancement beads:
+- `miroir-zc2.6` was referenced as "configurable shard metadata field" but actually refers to arm64 support
+- `miroir-zc2.7` and `miroir-zc2.8` were referenced but do not exist
+
+**Fix applied**: Replaced specific bead references with a descriptive "Future Enhancements" table that:
+- Describes each enhancement without referencing non-existent beads
+- Provides priority levels (P2-P4) for future planning
+- Maintains traceability without creating false bead dependencies
+
+### 2. Matrix Coverage Verification
+
+The matrix comprehensively enumerates 9 dump variants that require broadcast fallback:
+
+1. **Tasks history** - Not reproducible via public API
+2. **Dumps with existing `_miroir_shard` field** - Field collision conflict
+3. **Pre-v1.0 dump format** - Incompatible NDJSON structure
+4. **Internal LMDB state** - Cache warming not reproducible
+5. **Snapshot-based dumps** - Binary format, not NDJSON
+6. **Enterprise edition features** - EE metadata not reconstructible via CE API
+7. **Old-style settings format (v1.0-v1.2)** - Schema changes
+8. **Large single-document payloads** - OOM risk
+9. **Corrupted or partial dumps** - Neither mode handles corruption
+
+### 3. Task-Mentioned Variants Verified
+
+All variants mentioned in the task description are covered:
+- ✅ Dumps from older Meilisearch versions with pre-v1.37 schema → Covered as "Pre-v1.0 dump format" and "Old-style settings format"
+- ✅ Dumps with custom keys → Covered as fully compatible (Custom API keys)
+- ✅ `_miroir_shard` field conflict → Covered with dedicated section
+
+### Acceptance Criteria Met
+
+- [x] Matrix published at `docs/dump-import/compatibility-matrix.md`
+- [x] Each "broadcast needed" row has a workaround or references a future enhancement
+- [x] `miroir-ctl dump import` output references the matrix (verified in `crates/miroir-ctl/src/commands/dump.rs`)
+
+### CLI Integration Verified
+
+The dump import command help text references the matrix:
+```rust
+/// See compatibility matrix: docs/dump-import/compatibility-matrix.md
+```
+
+## Changes Made
+
+- `docs/dump-import/compatibility-matrix.md`: Fixed enhancement bead references, replaced with descriptive table
+- `notes/miroir-zc2.5.md`: Updated to reflect actual work completed
