Wave 19: production-grade SDPO via ComposerDataCollator + adapter + collator fixes
Adds the full production data path Wave 18 deferred: ClaudeCodeIngester → adapter → ComposerDataCollator → compose_loss with proper hint injection at detected error sites. Two rounds of 3-reviewer cross-family review caught a critical SDPO mask alignment bug in round 1; round 2 verified the fix. NEW infrastructure: - composer_replication/ingestion/trace_examples.py: claude_states_to_trace_examples() adapter walks ClaudeCodeIngester output, detects [TOOL_RESULT (ERROR)] tagged user turns, marks the recovery assistant turn with tool_error="<kind>" so ComposerDataCollator._is_error_turn picks it up. Default classifier handles file_not_found, permission_denied, command_not_found, syntax_error, connection_error; users can pass custom error_kind_fn. Backward-scan finds errors even when intervening user turns separate the error from recovery. - composer_replication/ingestion/tests/test_trace_examples_adapter.py: 14 tests pinning the adapter contract (error detection, classifica…03bf323

Wave 10 — packaging: composer_replication is now pip-installable
Promotes the framework from "skeleton scattered across spike directories" to a proper installable Python package (closes vision-validation gap V4). What's new: pyproject.toml at repo root - Hatchling build backend - Python ≥3.10 - Core deps: torch≥2.0, transformers≥4.46 - Optional extras: replay (httpx), diloco (torchft-nightly), train (trl, peft, accelerate, datasets), dev (everything + pytest, ruff) - Project URLs point to the HF repo + Discussions composer_replication/ package (8 modules) - __init__.py re-exports the framework's public API: compose_loss, LossComponents, build_batch (Spike 006) generalized_jsd_loss (verified port of OPSD) ClaudeCodeIngester, IngestionStats, SYSTEM_PROMPT (Spike 007) TraceState, DPOPair, TeacherSpec, replay_trace, extract_dpo_pairs, DEFAULT_TEACHERS (Spike 001/005) ComposerReplicationTrainer (Spike 005, TRL subclass) make_diloco_outer_loop …ac05fbf
