# Phase 10: Pipeline Stabilization — Summary

## What Was Built

Phase 10 made the LLM pipeline reliable enough to work with GLM's rate limits and token constraints.

### Core Changes

| Component | Change | Purpose |
|-----------|--------|---------|
| `llm/providers/factory.py` | Added `retry_base_delay` to `ProviderConfig` | GLM needs 30s base, Anthropic uses 1s |
| `llm/providers/factory.py` | Added `get_retry_delay()` | Returns provider-specific delay |
| `llm/retry.py` | Added `provider_name` parameter to `with_llm_retry` | Enables provider-aware backoff |
| `llm/retry.py` | Added schema validation errors to transient patterns | Retries when LLM omits required fields |
| `llm/structured.py` | Added `TruncationResult` dataclass | Encapsulates truncation detection |
| `llm/structured.py` | Added `detect_truncation()` | Identifies incomplete JSON responses |
| `llm/missions/generator.py` | Added `generate_category_missions_multi()` | Multi-call generation with resume |
| `llm/missions/generator.py` | Added `provider_name` to `generate_category_missions()` | Wires provider delays |
| `llm/missions/pipeline.py` | Added `provider_name` and `category_cooldown` params | Provider-aware pipeline |
| `llm/missions/context.py` | Fixed `tokens_used` counter bug | Security section now respects budget |
| `llm/briefing/generator.py` | Added `provider_name` parameter | Wires provider delays to briefing |

### Post-Build Fixes

1. **Output 6 (429 errors):** `provider_name` wasn't being passed through the call chain
   - Fixed in `briefing/generator.py` and `testing_script.py`

2. **Output 7 (schema validation):** Schema errors weren't retried
   - Added "did not match expected schema" to transient patterns in `retry.py`

## Files Modified

- `src/unfamiliar/llm/providers/factory.py`
- `src/unfamiliar/llm/retry.py`
- `src/unfamiliar/llm/structured.py`
- `src/unfamiliar/llm/missions/generator.py`
- `src/unfamiliar/llm/missions/pipeline.py`
- `src/unfamiliar/llm/missions/context.py`
- `src/unfamiliar/llm/briefing/generator.py`
- `tests/test_llm_retry.py` (2 new tests)

## Test Results

- **Total tests:** 725 passing
- **New tests:** 2 (schema validation retry behavior)

## Verification

### Agent Verification (Complete)
- [x] All 725 unit tests pass
- [x] `get_retry_delay("glm")` returns 30.0
- [x] `with_llm_retry` uses provider-specific delays
- [x] Schema validation errors are retried

### User Verification (Complete)
- [x] Testing script ran successfully twice with GLM
- [x] Rate limit recovery with 30s+ delays working
- [x] Schema validation retry working

## Key Metrics

| Metric | Before | After |
|--------|--------|-------|
| GLM retry base delay | 1s | 30s |
| Schema errors retried | No | Yes |
| Truncation resume | No | Yes |
| `tokens_used` accuracy | Broken | Fixed |
