Audit findings & fixes:
- temperature was never set (API defaulted to 1.0) → now explicit 0.0 for deterministic JSON
- llm_max_tokens=65536 exceeded hard_limit=32768 → aligned to 32768
- Output ratio estimates were 5-30x too high (based on actual pipeline data):
stage2: 0.6→0.05, stage3: 2.0→0.3, stage4: 0.5→0.3, stage5: 2.5→0.8
- request_params now structured as api_params (what's sent to LLM) vs pipeline_config
(internal estimator settings) — no more ambiguous 'hard_limit' in request params
- temperature=0.0 sent on both primary and fallback endpoints
Three resilience improvements to the pipeline:
1. LLMResponse(str) subclass carries finish_reason metadata from the LLM.
_safe_parse_llm_response detects truncation (finish=length) and raises
LLMTruncationError instead of wastefully retrying with a JSON nudge
that makes the prompt even longer.
2. Stage 4 classification now batches moments (20 per call) instead of
sending all moments in a single LLM call. Prevents context window
overflow for videos with many moments. Batch results are merged with
reindexed moment_index values.
3. run_pipeline auto-resumes from the last completed stage on error/retry
instead of always restarting from stage 2. Queries pipeline_events for
the most recent run to find completed stages. clean_reprocess trigger
still forces a full restart.

Stage 4 classification was truncating (finish=length) because the 0.15x
output ratio underestimated token needs. Inflated all stage ratios,
bumped the buffer from 20% to 50%, raised the floor from 2048 to 4096,
and fixed _safe_parse_llm_response to forward max_tokens on retry
instead of falling back to the 65k default.

Auto-mode commit 7aa33cd accidentally deleted 78 files (14,814 lines) during M005
execution. Subsequent commits rebuilt some frontend files but backend/, alembic/,
tests/, whisper/, docker configs, and prompts were never restored in this repo.
This commit restores the full project tree by syncing from ub01's working directory,
which has all M001-M007 features running in production containers.
Restored: backend/ (config, models, routers, database, redis, search_service, worker),
alembic/ (6 migrations), docker/ (Dockerfiles, nginx, compose), prompts/ (4 stages),
tests/, whisper/, README.md, .env.example, chrysopedia-spec.md
