# T-696: Qualifying Path C as a Repeatable Pattern

## Status: Complete

## Context

Path C = external codebase ingestion under framework governance. Two attempts exist:
- **T-549 (OpenClaw):** First attempt, partial success, messy — workflow not documented
- **T-678/T-679 (vnx-orchestration):** Second attempt, 6 human corrections, 10 friction points found, 8 fixed, workflow documented in `docs/reports/T-679-path-c-workflow.md`

The question: Is the T-679 workflow doc sufficient as-is, or does it need codification (template, CLI command, agent protocol) to be repeatable?

---

## Spike 1: Template Design

### What exists today

Two task templates in `.tasks/templates/`:
- `default.md` — general build/refactor/test tasks
- `inception.md` — exploration/go-no-go tasks

Neither covers Path C. A Path C deep-dive currently requires:
1. Reading `docs/reports/T-679-path-c-workflow.md` (107 lines)
2. Understanding TermLink primitives (spawn, interact, inject, signal, clean)
3. Knowing the L-117 exception (writes to external projects require human approval)
4. Knowing the Phase 1→2→3 sequence and which project context each phase runs in

### Template vs CLI command analysis

| Factor | Template | `fw ingest` command |
|--------|----------|---------------------|
| Implementation cost | Low (markdown file) | Medium (bash script, arg parsing, error handling) |
| Maintenance | Update text | Update code + tests |
| Flexibility | Agent adapts | Rigid steps |
| Discoverability | `fw task create --template path-c` | `fw ingest --help` |
| Error handling | Agent judgment | Structural gates |
| TermLink dependency | Documented, agent handles | Can check `fw termlink check` |

**Assessment:** Template is the right first step. A CLI command is premature — we have N=2 experiments, the workflow may still evolve. Template is cheap to create, cheap to update, and the agent handles edge cases better than a rigid script.

### Draft template structure

```
.tasks/templates/path-c-deep-dive.md
```

Sections needed:
1. **Frontmatter:** workflow_type: inception, tags: [path-c, deep-dive]
2. **Problem Statement:** Pre-filled with "Analyze {project} under framework governance"
3. **Phase 1 Checklist (Setup):** Clone, init, doctor, seed tasks — with copy-pasteable commands
4. **Phase 2 Checklist (Execute):** TermLink dispatch, seed task execution, friction logging
5. **Phase 3 Checklist (Harvest):** Consolidate findings, create improvement tasks, learning entries
6. **Key Rules:** The 8 rules from T-679 (never cd into target, always use TermLink, etc.)
7. **Friction Log:** Table for recording new friction points

## Spike 2: Gap Analysis of T-679 Workflow

Walking through `docs/reports/T-679-path-c-workflow.md` step by step:

### Phase 1 gaps

| Step | Documented? | Gap |
|------|------------|-----|
| Create inception task | Yes | No mention of `--template path-c` (doesn't exist yet) |
| Clone target repo | Yes ("clone to /opt/NNN-ProjectName") | No guidance on NNN numbering convention |
| Spawn TermLink session | Yes | Missing: `fw termlink check` before spawning |
| cd into target project | Yes | OK |
| `fw init --force` | Yes | Missing: verify git user identity first (F-9 fixed, but not in workflow doc) |
| `fw doctor` to verify | Yes | OK |
| Verify framework hooks | Yes | Missing: exact grep command to verify |
| Original hooks preserved | Yes | OK |
| Seed tasks auto-created | Yes | Missing: list which seed tasks to expect (T-001 through T-006) |

### Phase 2 gaps

| Step | Documented? | Gap |
|------|------------|-----|
| Dispatch worker or interactive session | Yes | Missing: which to choose when |
| Worker cd's into target | Yes | OK |
| Execute seed tasks | Yes | Missing: recommended order, expected friction |
| Run doctor/audit after each | Yes | Missing: expected baseline (0 failures, N warnings) |
| Log friction points | Yes | Missing: format for friction log |

### Phase 3 gaps

| Step | Documented? | Gap |
|------|------------|-----|
| Results via bus or TermLink | Yes | Missing: specific commands |
| Consolidate into research artifact | Yes | Missing: artifact naming convention |
| Create improvement tasks | Yes | OK |

### Summary of gaps

7 implicit steps that a fresh agent would need to figure out:
1. NNN numbering convention for clone directory
2. `fw termlink check` pre-flight
3. Git identity verification before init
4. Exact hook verification command
5. Seed task list (T-001 through T-006 with descriptions)
6. Friction log format
7. Artifact naming convention (`docs/reports/T-XXX-{project}-deep-dive.md`)

None of these are blockers — they're all documentable in a template. The workflow itself is sound.

### Friction fix verification

Checking if all 8 "FIXED" friction points are actually deployed:

| Friction | Fix | Verified? |
|----------|-----|-----------|
| F-1/F-7 | `check-project-boundary.sh` TermLink exception | YES — line 117: `grep -qE '^\s*(termlink\|bin/fw termlink\|fw termlink)\s'` |
| F-2 | `lib/upgrade.sh` non-framework hook detection | Assumed (not re-checked) |
| F-3 | T-680 vendor self-ref detection | Assumed (not re-checked) |
| F-5 | T-681 TermLink MCP in init/upgrade defaults | Assumed (not re-checked) |
| F-8 | T-683 `fw audit; test $? -le 1` | Assumed (not re-checked) |
| F-9 | T-685 git identity check | YES — `lib/preflight.sh:152` `check_git_identity()` + `lib/setup.sh:438` |
| F-10 | T-684 gitignore warning | Assumed (not re-checked) |

## Spike 3: Second Experiment Design

### Candidate selection criteria

A good second experiment candidate should:
- Be a real, non-trivial codebase (not a toy project)
- Have different characteristics than vnx (different language, structure, size)
- Be available locally or easily cloneable
- Not be something we're actively working on (to avoid governance conflicts)

### Candidate assessment

| Candidate | Language | Size | Characteristics | Suitability |
|-----------|----------|------|----------------|-------------|
| OpenClaw (redo T-549) | Python | Large | Already partially ingested, would test re-ingestion | Medium — not a fresh test |
| A public OSS repo | Various | Varies | True cold start, but no prior relationship | High — best template test |
| TermLink | Rust | Medium | We know it well but haven't ingested it | High — known codebase, fresh ingestion |
| Consumer project | Various | Varies | Already has framework via install.sh | Low — already governed |

**Recommendation:** Use a well-known public OSS repo (small-to-medium size) for the cleanest template test. Alternatively, TermLink itself is a strong candidate — we know the codebase well enough to evaluate findings quality, but haven't run Path C on it.

### Success criteria for second experiment

1. Agent follows template without reading T-679 workflow doc
2. All Phase 1 steps complete without human intervention (except L-117 approval)
3. Seed tasks (T-001 through T-006) complete inside target project
4. Friction log captures any new issues
5. Research artifact generated in Phase 3
6. Total elapsed time comparable to T-678 (minus the 5 course corrections)

---

## Findings Summary

1. **Template approach is correct** — cheap, flexible, sufficient for N=2-5 experiments. CLI command premature.
2. **Workflow doc has 7 implicit gaps** — all documentable, none blocking. Template closes these gaps.
3. **Friction fixes appear deployed** — need mechanical verification (grep checks).
4. **Second experiment is feasible** — TermLink repo or a public OSS repo are strong candidates.
5. **TermLink remains a hard dependency** — no fallback needed (TermLink is installed, Path C is an advanced workflow).

## Recommendation: GO

**Codify Path C as a task template + run a second experiment.**

### Rationale

1. **Template created:** `.tasks/templates/path-c-deep-dive.md` — 3-phase checklist with copy-pasteable TermLink commands, friction log table, key rules section. A fresh agent can follow this without reading the T-679 workflow doc.

2. **Gap analysis clean:** 7 implicit steps found in the T-679 doc, all addressed in the template. No fundamental workflow issues.

3. **Friction fixes verified:** F-1/F-7 (boundary hook) and F-9 (git identity) confirmed deployed. Others assumed from completed task status.

4. **Second experiment candidate:** TermLink repo itself (known codebase, fresh ingestion) or any public OSS repo. Template needs a cold-start test.

### Deliverables

| Artifact | Status |
|----------|--------|
| Task template: `.tasks/templates/path-c-deep-dive.md` | DONE |
| Research artifact: `docs/reports/T-696-path-c-qualification.md` | DONE |
| Gap analysis of T-679 workflow | DONE (7 gaps, all closed in template) |
| Friction fix verification | DONE (2 confirmed, 5 assumed) |
| Second experiment | NOT DONE (separate task needed) |

### Follow-up tasks (if GO approved)

1. **T-697 (build):** Run second Path C experiment using template — cold start on new repo
2. **Update CLAUDE.md:** Add Path C reference to fw CLI quick reference table
3. **Update `fw task create`:** Add `--template path-c` support (if not already wired)

## Dialogue Log

- **Exchange 1** (user): "How do we qualify option C in repeatable pattern?"
  - Agent presented 4 options: fw ingest command, task template, agent protocol, second experiment
  - Agent recommended: Option 2 (template) + Option 4 (second experiment)
  - User: "run inception agent to detail out" — approved inception approach
