Normalization Before Comparison + +Auto-generated fields (timestamps, invocation IDs, internal counters) differ +between backends. The normalizer strips these before comparison, keeping only +business-relevant fields: author, text content, state deltas. + +### 2. JSONL Fixture Format + +Each replay case is persisted as a JSONL file where each line is a typed step +(case_header, event, memory_write, memory_query, summary_step, track_event). +This is human-readable, diff-friendly, and language-agnostic — Go and Python +can share the same fixtures. + +### 3. Backend Gating via Environment Variables + +Redis tests are gated behind the `REDIS_URL` environment variable. If Redis is +unavailable, the tests gracefully skip rather than failing. InMemory and SQLite +tests always run (SQLite uses `:memory:` mode). + +### 4. Recursive Diff with Allowed Diffs + +The `recursive_diff()` function traverses the entire snapshot tree (dicts, +lists, primitives). `DiffEntry.allowed` tracks which differences are expected +(e.g., summary text may differ slightly between backends due to truncation +semantics) vs. those that indicate a real bug. + +### 5. Alignment with Go Reference + +The data types (`EventSpec`, `MemoryWriteSpec`, `ReplayCase`, etc.) and 10 test +scenarios mirror the Go implementation in `trpc-agent-go/session/replaytest/`, +enabling cross-SDK consistency validation in the future. + +## Replay Execution Flow + +``` +For each ReplayCase: + 1. Create session (app_name, user_id, session_id) + 2. Apply initial_state + 3. For each EventSpec: append event to session + 4. For each MemoryWriteSpec: store memory entry + 5. For each MemoryQuerySpec: search memory + 6. For each SummaryStep (at after_event_index): trigger summary + 7. For each TrackEventSpec: record track event + 8.
