# Interactive registry maintain with llm-connect automation

Follow-up to **REUSE-WP-0013** (`establish`, `update`, `stats`). Workstation
rollout (**REUSE-WP-0014**) gave every sibling repo a registry scaffold; operators
still maintain entries manually or run `reuse-surface update` as a **non-interactive
report**. LLM maturity hints (`--suggest-maturity`) dump JSON for human review
with no apply path.

This workplan closes the **registry maintenance loop** from inside each domain
repo: interactive prompting for judgment calls, full automation for safe and
high-confidence changes, both backed by the existing **llm-connect** HTTP bridge.

**Baseline vector:** `D5 / A4 / C5 / R3`  
**Target vector:** `D5 / A4 / C5–C6 / R3` (tooling depth; reliability unchanged
until consumer telemetry program)

## Problem statement

| Pain | Today (WP-0013) | Target |
|---|---|---|
| Update registry after code changes | `update` prints suggestions; user must remember `--apply` | Guided session with per-change prompts |
| Maturity / evidence refresh | `--suggest-maturity` → JSON only | Structured LLM patches with review or auto-apply |
| Publish hygiene | Manual validate → commit → publish-check | `maintain` chains update → validate → optional publish-check |
| Agent vs human UX | Same stdout for both | TTY prompts for humans; JSON/event stream for agents |
| Sibling repo friction | `validate` defaults to install root | Auto-detect `registry/` in cwd |

## Design principles

1. **Deterministic first** — vector drift, missing index rows, and cited artifact
   paths apply without LLM; same safe-apply list as WP-0013-T06, extended.
2. **Interactive by default in TTY** — `reuse-surface maintain` prompts before
   any non-deterministic write; non-TTY requires `--yes` or `--auto`.
3. **Full automation is explicit** — `--auto` applies deterministic patches plus
   LLM proposals that pass schema validation and evidence gates; never silent
   promotion above configured ceilings (default: no auto D/A/C/R jumps > 1 level).
4. **LLM optional** — deterministic-only paths work without `LLM_CONNECT_URL`;
   LLM steps skip gracefully with a clear message.
5. **Validate gate** — every write path ends with `reuse-surface validate --root
   <repo>`; failed validation rolls back the session batch (atomic apply).
6. **Evidence-bound promotions** — auto-apply for maturity changes requires
   cited repo paths (tests, workflows, docs) present on disk; align checks with
   `specs/CapabilityMaturityStandard.md`.
7. **Boundary** — reuse-surface does not host models; llm-connect owns routing
   and credentials (`POST {LLM_CONNECT_URL}/execute`).

## Proposed CLI surface

```bash
# Interactive maintain (default in TTY)
cd ~/state-hub
export LLM_CONNECT_URL=http://127.0.0.1:8088   # optional
reuse-surface maintain
reuse-surface maintain --from-git-since origin/main
reuse-surface maintain --capability capability.statehub.workstream-coordinate

# Full automation (CI, agents, pre-commit)
reuse-surface maintain --auto --from-git-since HEAD~1
reuse-surface maintain --auto --no-llm          # deterministic only

# Non-interactive apply-all-safe (current update behavior, preserved)
reuse-surface update --all --from-git-since origin/main --apply

# Federation publish helper (chains maintain + validate + publish-check)
reuse-surface maintain --publish --raw-url https://gitea.../capabilities.yaml
```

### Interactive prompt flow (TTY)

```text
reuse-surface maintain
  → collect repo signals (git diff, index drift, roster stats)
  → deterministic suggestions (always listed first)
  → optional LLM patch proposals per capability (llm-connect)
  → for each pending change:
       [a]pply  [s]kip  [e]dit in $EDITOR  [q]uit  [A]pply all safe
  → atomic write + validate
  → summary: files changed, remaining manual items, publish reminder
```

### Automation tiers (`--auto`)

| Tier | Applies without prompt |
|---|---|
| `safe` | Deterministic patches (vector drift, evidence path append) |
| `llm-metadata` | LLM `consumer_feedback`, `notes`, non-level field updates |
| `llm-promote` | Single-step maturity bumps with on-disk evidence citations |

Configure ceiling via `--auto-max-delta 1` (default) or `--auto-max-delta 0` to
disable promotions.

## Suggested execution order

```text
T01 registry-patch JSON schema + LLM prompt templates
  → T02 expand deterministic signal collectors
  → T03 interactive prompt module (TTY + non-TTY)
  → T04 maintain command (orchestrator)
  → T05 LLM patch apply path with evidence gates
  → T06 --auto mode + atomic batch apply/rollback
  → T07 validate cwd auto-detect; index.updated bump
  → T08 sibling integration (Makefile template, optional hook generator)
  → T09 docs, tests, gap-analysis priority 28
```

## Dependencies

| Dependency | Owner | Notes |
|---|---|---|
| llm-connect | llm-connect | `LLM_CONNECT_URL`; mocked in pytest |
| WP-0013 modules | reuse-surface | `registry_update.py`, `llm_bridge.py`, `establish.py` |
| Maturity standard | reuse-surface | Promotion evidence rules in prompts and gates |
| Sibling repo adoption | Domain owners | Run `maintain` in each checkout; optional CI step |

## Add Registry Patch Schema And LLM Templates

```task
id: REUSE-WP-0016-T01
status: done
priority: high
state_hub_task_id: "f5daf384-ca4e-42ec-8530-bf5d46155284"
```

Define `schemas/registry-patch.schema.json` for structured update proposals
(consumed by interactive and `--auto` paths):

- `patches[]`: `{ capability_id, kind, confidence, rationale, field_path, value |
  append, promotion_history_entry }`
- `kinds`: `vector_sync`, `evidence_append`, `artifact_append`, `maturity_promote`,
  `consumer_feedback`, `relation_add`, `index_row_add`
- `evidence_citations[]`: repo-relative paths supporting each patch

Add prompt builders in `reuse_surface/registry_update.py` (or
`reuse_surface/maintain_llm.py`):

- `build_maintain_prompt(repo_root, capability_id, git_since, context_files)`
- Schema-constrained JSON via `request_json_object` + validator
- Reuse maturity level definitions from `CapabilityMaturityStandard.md` in prompt
  context (summary table, not full doc)

Pytest: fixture repo + mocked llm-connect returning valid/invalid patches.

## Expand Deterministic Signal Collectors

```task
id: REUSE-WP-0016-T02
status: done
priority: high
state_hub_task_id: "55e6d943-6237-4332-9b01-2fa42aceff1f"
```

Extend `collect_deterministic_suggestions` in `registry_update.py`:

| Signal | Suggested field |
|---|---|
| `.gitea/workflows/*.yml` changed | `evidence.tests` or `evidence.documentation` |
| `docs/**` changed | `evidence.documentation` |
| `pyproject.toml` / `[project.scripts]` added | `availability.current_artifacts` |
| New `registry/capabilities/*.md` without index row | `index_row_add` patch |
| `index.updated` stale vs last git touch on `registry/` | bump `updated` date |
| Missing entry file for index row | `missing_entry` (blocking warning) |

Keep `--apply` safe-list explicit in code (document in module docstring). Add
regression tests in `tests/test_registry_update.py`.

## Implement Interactive Prompt Module

```task
id: REUSE-WP-0016-T03
status: done
priority: high
state_hub_task_id: "fe3a2e99-8c40-48a7-9d70-0e92b48146d2"
```

New module `reuse_surface/interactive.py`:

- Detect TTY (`sys.stdin.isatty()`)
- `prompt_patch(patch) -> Literal["apply","skip","edit","quit"]` with short
  summary (kind, capability_id, rationale, field preview)
- `prompt_batch(patches) -> list[patch]` supporting **Apply all safe** for
  deterministic kinds only
- Non-TTY: raise unless `assume_yes` / `auto_mode` set; emit JSON lines
  (`{"event":"suggestion",...}`) for agent consumers
- Optional `$EDITOR` flow: write temp YAML snippet, re-parse on save

No llm-connect dependency. Pytest with stdin mocked via `io.StringIO`.

## Implement maintain Command

```task
id: REUSE-WP-0016-T04
status: done
priority: high
state_hub_task_id: "6e3a7b3d-1037-49ed-ad7c-341d21c333da"
```

Add `reuse-surface maintain` in `cli.py` (or alias `update --interactive` if
prefer fewer top-level verbs — default to **`maintain`** as the user-facing
entry point):

**Flags:**

| Flag | Purpose |
|---|---|
| `--path` | Repo root (default cwd) |
| `--capability` / `--all` | Scope |
| `--from-git-since` | Git ref for change detection |
| `--llm-url` | Override `LLM_CONNECT_URL` |
| `--no-llm` | Skip LLM phase |
| `--publish` | Run `establish --publish-check` after successful validate |
| `--raw-url` | Required when `--publish` |
| `--format json` | Machine-readable session result |

**Flow:**

1. Run T02 collectors
2. If LLM enabled: run T01 prompts per capability in scope
3. Merge deterministic + LLM into ordered patch list (deterministic first)
4. T03 interactive selection (unless `--auto` — T06)
5. T05 apply + T06 atomic validate

Preserve existing `update` command unchanged for scripting backward compatibility.

## LLM Patch Apply Path With Evidence Gates

```task
id: REUSE-WP-0016-T05
status: done
priority: medium
state_hub_task_id: "f0baa772-b7f0-4143-9fd9-9c96db17f532"
```

Implement `apply_patches(repo_root, patches) -> list[str]`:

- Reuse `apply_deterministic_suggestions` for overlapping kinds
- New writers: `promotion_history` append, `maturity.*.current` with vector
  sync to index, `consumer_feedback` append, `relations.*` append (optional v1)
- **Evidence gate:** for `maturity_promote`, require every
  `evidence_citations` path to exist under `repo_root`; reject patch if not
- **Level gate:** refuse promotion if delta > `--auto-max-delta` unless
  interactive user confirms
- Bump `registry/indexes/capabilities.yaml` `updated` field on any write

Pytest: promote with/without evidence files; vector/index consistency after apply.

## Implement --auto Mode And Atomic Batch

```task
id: REUSE-WP-0016-T06
status: done
priority: medium
state_hub_task_id: "bd8f6243-24a3-44f8-9824-4cc2518ad8d9"
```

`maintain --auto`:

- Apply all `safe` deterministic patches
- Apply LLM patches with `confidence >= --auto-confidence` (default `high`) and
  passing evidence gates
- `--auto-max-delta` (default `1`) caps promotion steps per dimension per session
- `--yes` on non-TTY equivalent to `--auto` with default thresholds

**Atomic batch:** write all entry/index changes to temp files under
`.reuse-surface-session/`; on validate success, rename into place; on failure,
discard and print validator errors.

Exit codes: `0` ok, `1` validation/schema failure, `2` partial skip (no writes).

## Validate Cwd Auto-Detect And Publish Helper

```task
id: REUSE-WP-0016-T07
status: done
priority: low
state_hub_task_id: "a61c0843-f44b-4e75-9043-7d042087e015"
```

- When `--root` / `--path` omitted and `./registry/indexes/capabilities.yaml`
  exists, default repo root to cwd (validate, update, maintain, stats)
- `maintain --publish --raw-url` chains: maintain session → validate →
  `establish.publish_check` → print pass/fail markdown
- Document raw URL convention in session summary when `REUSE_SURFACE_RAW_URL` set

## Sibling Integration Templates

```task
id: REUSE-WP-0016-T08
status: done
priority: low
state_hub_task_id: "ec2d58a3-c797-464b-9fb3-464f71360c9c"
```

Ship copy-paste artifacts (not installed into sibling repos automatically):

- `templates/Makefile.registry.fragment` — `registry-maintain`, `registry-check`
- `templates/git-hook.pre-commit.registry` — `maintain --auto --no-llm` when
  `registry/` changed
- `establish --scaffold` append: optional `--hook` writes `.git/hooks/pre-commit`
  (refuse overwrite unless `--force`)

Dogfood: run against `state-hub` checkout when available.

## Documentation, Tests, And Gap Note

```task
id: REUSE-WP-0016-T09
status: done
priority: low
state_hub_task_id: "85f8f549-7df9-493c-b43b-f1b67af3ee6c"
```

- `tools/README.md` — `maintain` command reference; interactive vs `--auto`
- `docs/RegistryFederation.md` — link maintain + publish to sibling onboarding
- `registry/README.md` — operator checklist after `maintain` session
- `docs/IntentScopeGapAnalysis.md` — add priority **28** (registry maintenance
  automation); mark open
- `SCOPE.md` — extend "What Is Possible Now" when T04 ships
- CI: `maintain --auto --no-llm` on reuse-surface self-registry (informational
  or gated); no live llm-connect in CI
- Pytest count increase; `reuse-surface validate` unchanged for default path

---

## Acceptance

- [x] `reuse-surface maintain` in TTY walks through suggestions with apply/skip/edit
- [x] `maintain --auto --no-llm` applies deterministic patches and validates atomically
- [x] LLM patches apply only with schema validation + evidence gates
- [x] `maintain --publish --raw-url` reports federation publish pass/fail
- [x] Non-TTY without `--auto`/`--yes` fails with clear message (no silent writes)
- [x] `validate` defaults to cwd when local `registry/` index exists
- [x] All new behavior documented; gap priority 28 recorded

## Completion notes (2026-06-17)

- Modules: `maintain.py`, `maintain_llm.py`, `patches.py`, `interactive.py`
- Schema: `schemas/registry-patch.schema.json`
- Templates: `templates/Makefile.registry.fragment`, `templates/git-hook.pre-commit.registry`
- CLI: `reuse-surface maintain`; `establish --scaffold --hook`
- Tests: `tests/test_maintain.py`, `tests/test_interactive.py` (59 pytest total)

## Out of scope

- Hub cache invalidation webhooks (gap priority from §3.1 — separate workplan)
- Auto `hub register` (still operator step with token)
- Embedding / ML overlap detection (keep `overlaps` heuristic)
- llm-connect hosting or provider configuration inside reuse-surface
- Fully unattended maturity promotion without evidence citations

## Dogfood target

From `~/state-hub` (or any roster repo with `publish_check: pass`):

```bash
export LLM_CONNECT_URL=http://127.0.0.1:8088
reuse-surface maintain --from-git-since origin/main
reuse-surface maintain --auto --from-git-since HEAD~3
reuse-surface maintain --publish \
  --raw-url https://gitea.coulomb.social/coulomb/state-hub/raw/main/registry/indexes/capabilities.yaml
```

Success: registry files updated, `validate --root .` passes, publish-check 200.
