# comprehensive-learning — Session Learning Pipeline

Single fire-and-forget skill running Phases 1–9 on **all machines** and Phases 10a+10
(cross-machine compilation + report) on **dev-primary only**.

> **Full phase specs**: `references/pipeline-detail.md` — read it when you need
> signal sources, extraction rules, candidate formats, or state file details.

## Mode-Based Routing

```bash
MACHINE=$(hostname -s 2>/dev/null || hostname | cut -d. -f1 | tr '[:upper:]' '[:lower:]')
case "$MACHINE" in
  dev-primary) CL_MODE="full" ;;
  dev-secondary) CL_MODE="contribute" ;;
  licensed-win-1|licensed-win-2) CL_MODE="contribute" ;;
  *) CL_MODE="contribute" ;;
esac
# All modes run Phases 1–9. Only 'full' runs Phase 10a (compilation) + Phase 10 (report).
```

## Cross-Machine Data Flow

| Machine | Commits | Notes |
|---------|---------|-------|
| dev-secondary | `candidates/`, `corrections/`, `patterns/`, `session-signals/` | Open-source CFD/dev |
| licensed-win-1 | `candidates/`, `corrections/`, `session-signals/`, `patterns/` | OrcaFlex/ANSYS |
| licensed-win-2 | `candidates/` | Windows; no AI CLIs |

dev-primary `git pull` in Phase 10a picks up all machines' committed derived state.

## Pipeline Summary

Run phases sequentially. Non-mandatory phases log failure and continue. Fatal failures
in Phases 1 or 4 set `_PIPELINE_EXIT=1`. Phase 10 always runs via `trap EXIT`.

| Phase | Name | Mandatory | Short description |
|-------|------|:---------:|-------------------|
| 1 | Insights | ✓ | Extract skill usage, tool patterns, session-quality signals from all log sources |
| 1b | Drift Detection | dev-primary | Detect python_runtime/file_placement/git_workflow violations in yesterday's log |
| 2 | Reflect | — | Invoke /reflect against reflect-history/ and trends/ |
| 3 | Knowledge | — | Invoke /knowledge; update patterns/ |
| 3b | Memory Compaction | — | Compact MEMORY.md + topic files |
| 3c | Memory Curation | — | Promote stable patterns, expire stale entries |
| 4 | Improve | ✓ | Invoke /improve; update skills + rules from candidates/ |
| 5 | Correction Trends | — | Analyze corrections/ for recurring failure patterns |
| 6 | WRK Feedback + Ecosystem | — | WRK quality review + skill usage frequency + ecosystem health |
| 7 | Action Candidates | — | Convert candidates/ entries to WRK items |
| 8 | Report Review | — | Review learning report for coherence |
| 9 | Skill Coverage Audit | weekly | Audit skill coverage via `identify-script-candidates.sh` + `skill-coverage-audit.sh`; include tier distribution from `skill-tier-report.py` (A/B/C/D per `config/skills/quality-tiers.yaml`) |
| 10a | Cross-Machine Compile | full only | git pull + aggregate from all machines |
| 10 | Report | always | Write report (trap EXIT) |

## Session Design: Lean by Default

Sessions are pure **multi-agent execution engines** — all brain directed at the task.
Analysis, maintenance, and learning are deferred to the nightly run.

| In-session | Nightly pipeline |
|------------|-----------------|
| WRK gate check + active-wrk set | All insight/reflect/knowledge/improve runs |
| Multi-agent implementation | Correction trend analysis |
| Fast signal capture (hooks write raw signals) | Candidate → WRK auto-creation |
| /session-start context load | Memory and skill file updates |
| Cross-review (Codex gate) | Ecosystem health checks |
| Commit + push | Session archive rsync |

**Must NOT run standalone during sessions:** `/insights`, `/reflect`, `/knowledge`,
`/improve`, `consume-signals.sh` heavy analysis, `ecosystem-health-check.sh`,
`session-end-evaluate.sh` scoring.

**Stop hooks:** one hook only, raw write, < 1 second. See WRK-304.

## Scheduling

Crontab entry (dev-primary, 22:00 nightly):
```bash
0 22 * * * cd /mnt/local-analysis/workspace-hub && \
  bash scripts/cron/comprehensive-learning-nightly.sh \
  >> .claude/state/learning-reports/cron.log 2>&1
```
Script: `scripts/cron/comprehensive-learning-nightly.sh`
— `git pull` is a hard gate; each `rsync` is independently `|| true`.

## Iron Law

> No learning pipeline phase (/insights, /reflect, /knowledge, /improve) shall run standalone during an active work session — learning is deferred to the nightly pipeline, always.

## Rationalization Defense

| Excuse | Reality |
|--------|---------|
| "I'll just run a quick /reflect to capture this insight" | /reflect consumes significant context and token budget. The nightly pipeline captures the same signals from hooks and logs — for free. |
| "The session is almost over, might as well run /improve now" | "Almost over" is when context is most valuable. Defer to nightly; hooks already captured the raw signals. |
| "This learning will be lost if I don't process it now" | Stop hooks write raw signals in < 1 second. The nightly pipeline processes them. Nothing is lost by deferring. |
| "The nightly cron might not run tonight" | Fix the cron job, do not work around it by running learning mid-session. Two problems are worse than one. |

## Red Flags

These phrases signal you are about to violate the Iron Law:
- "let me quickly run /insights before we continue"
- "I should capture this learning now"
- "running /improve won't take long"
- "the session is winding down anyway"
