# Content & Canon Build Tool Implementation Plan

> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.

**Goal:** Build a Python compiler that turns the authored Markdown bible (`content/lore/*.md`, prose + fenced `yaml` blocks) into validated, role-split runtime JSON (`content/world` client tree + `content/server` server-only tree), and promote Duncarrow as its acceptance test.

**Architecture:** A standalone `tools/content_build/` package with a four-stage pipeline — parse (Markdown → yaml blocks) → resolve/validate (a hard gate that aborts on any schema violation) → emit (route each field per the schema's role split) → write. Run manually (`python -m content_build`) or as a CI gate (`--check`, fails on stale-or-invalid). The build carries **no disposition numbers** — it validates rung *names* only; the client owns the band integers and the rung→midpoint mapping.

**Tech Stack:** Python 3.12, PyYAML (block parsing), pytest (TDD). No new runtime deps for the `api` proxy — the tool is dev/CI only. GDScript for the one client-loader change.

## Global Constraints

- **Locked schema — do not re-litigate.** The contract is fixed by `docs/superpowers/specs/2026-07-11-content-canon-schema-design.md`; this plan realizes `docs/superpowers/specs/2026-07-11-content-canon-build-tool-design.md`.
- **Charter §18 git flow:** this is non-doc code → all work on a branch off `dev` (`feature/content-build-tool`). Never commit to `master`. Doc/plan commits may land on `dev`. The human owns `dev → master`.
- **The build tool must not be importable by / bundled into the `api` proxy** (it ships to fly.io). It lives under `tools/`, never under `api/`.
- **Bands live in code, not the bible; the build never hardcodes a band integer.** Rung *names/order* come from the bible's `rule.disposition-ladder` `rungs:` field.
- **Only `status: canon` entries emit into shipping artifacts.** `candidate` entries still parse + validate (authors get errors early) but are not emitted.
- **Built JSON is committed.** Deterministic serialization (`json.dumps(obj, indent=2, sort_keys=True) + "\n"`) so `--check` diffs are stable.
- **The build never clears `content/world/npcs/`** — it is shared with legacy hand-authored NPCs (`fenn.json`, `cadwyn_vell.json`, `brannoc_thane.json`). The build overwrites only files it generates.
- **All commands run from the repo root**, using the repo venv and `PYTHONPATH=tools`:
  - Tests: `PYTHONPATH=tools .venv/bin/python -m pytest tools/content_build/tests -q`
  - Build: `PYTHONPATH=tools .venv/bin/python -m content_build`
  - Check: `PYTHONPATH=tools .venv/bin/python -m content_build --check`

### Task 1: Package scaffold, errors, and the Markdown parser

**Files:**
- Create: `tools/requirements-dev.txt`
- Create: `tools/content_build/__init__.py` (empty)
- Create: `tools/content_build/errors.py`
- Create: `tools/content_build/parse.py`
- Create: `tools/content_build/tests/__init__.py` (empty)
- Test: `tools/content_build/tests/test_parse.py`

**Interfaces:**
- Produces: `BuildError(message: str, source: str = "", entry_id: str = "")` with `.message/.source/.entry_id` attrs; `RawEntry` dataclass `{data: dict, source: str}`; `parse_bible(path: Path) -> list[RawEntry]`.

- [ ] **Step 1: Create the branch**

```bash
git checkout dev && git pull --ff-only 2>/dev/null; git checkout -b feature/content-build-tool
```

- [ ] **Step 2: Write the dev requirements and empty package files**

`tools/requirements-dev.txt`:
```
# Build-tool dev/CI deps. NOT installed into the api proxy runtime.
PyYAML==6.0.3
pytest==8.3.2
```

Create empty `tools/content_build/__init__.py` and `tools/content_build/tests/__init__.py`:
```bash
mkdir -p tools/content_build/tests/fixtures/valid
: > tools/content_build/__init__.py
: > tools/content_build/tests/__init__.py
```

- [ ] **Step 3: Write `errors.py`**

`tools/content_build/errors.py`:
```python
"""The single failure type. Every validation/parse problem raises BuildError so
the CLI can print a uniform 'BUILD FAILED: <what> [<id>] (<file:line>)'."""

        src = f" ({source})" if source else ""
        super().__init__(f"{message}{loc}{src}")
```

- [ ] **Step 4: Write the failing parser test**

    return entries
```

- [ ] **Step 7: Run the test to verify it passes**

Run: `PYTHONPATH=tools .venv/bin/python -m pytest tools/content_build/tests/test_parse.py -q`
Expected: PASS (4 passed).

- [ ] **Step 8: Commit**

**Note (accepted this cycle):** cross-status `related` integrity (a `canon` entry referencing a `candidate` entry, which would emit a dangling reference) is **not** checked — Duncarrow promotes atomically (all entries flip together). Revisit if a bible ever ships mixed-status.

### Task 4: Emit — routing, secrecy safety-check, write

**Files:**
- Create: `tools/content_build/emit.py`
- Create: `tools/content_build/tests/fixtures/valid/world.md`
- Test: `tools/content_build/tests/test_emit.py`

**Interfaces:**
- Consumes: `World` (Task 3), `Entry`, `LADDER_ID` (Task 3).
- Produces:
  - `dump_json(obj) -> str` — `json.dumps(obj, indent=2, sort_keys=True) + "\n"`.
  - `build_trees(world: World) -> tuple[dict, dict]` — `(client_files, server_files)`, each `{relpath: json_obj}` over **canon-status** entries only.
  - `check_secrecy(client_files: dict, world: World) -> None` — raises `BuildError` if any client record carrying a `body` originates from a `secrecy >= 3` entry.
  - `write_trees(client_files, server_files, world_dir: Path, server_dir: Path) -> None`.

- [ ] **Step 1: Write the valid fixture bible**

### Task 6: Promote Duncarrow (the acceptance run)

**Files:**
- Rename: `candidate-town.md` → `content/lore/duncarrow.md`
- Create: `content/lore/canon-roadmap.md`
- Create (BUILT, committed): `content/world/canon/*.json`, `content/world/topics/*.json`, `content/world/npcs/{mera-fenn,mayor-oswin-crell,harn-blackwood}.json`, `content/server/npcs/*.json`, `content/server/topics/*.json`
- Test: `tools/content_build/tests/test_duncarrow.py`

**Interfaces:**
- Consumes: the whole tool (Tasks 1–5).
- Produces: the committed Duncarrow artifacts; a green `--check`.

- [ ] **Step 1: Move the specimen into the lore tree**

```bash
git mv candidate-town.md content/lore/duncarrow.md
```

- [ ] **Step 2: Convert every fenced block to a `yaml` fence**

In `content/lore/duncarrow.md`, change every block's opening fence from ` ``` ` to ` ```yaml ` (the parser only reads `yaml`-tagged blocks). Leave prose commentary and closing fences as-is.

- [ ] **Step 3: Make each `knows` list valid YAML**

Rewrite every `knows` entry from the one-line `- fact: X   gate: Y` form to a proper mapping. Example (Mera Fenn's block becomes):

```yaml
knows:
  - {fact: rumor.elves-avoid-the-shrine, gate: neutral}
  - {fact: rumor.travelers-go-missing, gate: warm}
  - {fact: fact.militia-never-investigates, gate: warm}
  - {fact: fact.crells-guard-acts-alone, gate: trusted}
```

Apply the same conversion to Mayor Crell's and Harn Blackwood's `knows` lists.

- [ ] **Step 4: Apply the six specimen conformance fixes**

1. **Drop `knows: town.duncarrow`** links from `npc.mayor-oswin-crell` and `npc.harn-blackwood` (a canon entity may not appear in a `knows` list; the town is public and spoken freely).
2. **Rename** `shrine.the-white-antlers` → `place.the-white-antlers` (id namespace must equal type), and update **every** `related` reference to it — in `town.duncarrow`, `rumor.elves-avoid-the-shrine`, `rumor.travelers-go-missing`, `secret.crell-runs-slave-trade`.
3. **Add two canon stubs** so all `related` ids resolve (paste as new `yaml` blocks under the WORLD RULE section):

```yaml
id: region.the-tallow-reach
type: region
status: canon
secrecy: 0
related: []
body: >
  The Tallow Reach — the lowland march of grain towns and wool roads that
  Duncarrow sits at the edge of, feeding the pass trade.
```

```yaml
id: faction.elves
type: faction
status: canon
secrecy: 0
related: []
body: >
  The elven travellers of the road — no single polity, but the people whose
  passage through the White Antlers, and its recent absence, the town notices.
```

4. **Drop `secret.crell-runs-slave-trade`** from the **public** `person.mayor-oswin-crell` record's `related` (leave it `related: [town.duncarrow]`). The secret still links *to* the mayor, and the `npc.mayor-oswin-crell` layer still holds it at `gate: never` — that is the real bounded-move test.
5. **Add `rungs:`** to `rule.disposition-ladder` (keep the existing prose `body`):

```yaml
id: rule.disposition-ladder
type: rule
status: canon
secrecy: 0
related: []
rungs: [hostile, cold, neutral, warm, trusted]
body: >
  NPC trust toward the player is one of five ordered states:
  hostile < cold < neutral < warm < trusted. ...
```

6. **Flip every entry** `status: candidate` → `status: canon` (all of them — Duncarrow promotes atomically).

- [ ] **Step 5: Write the canon roadmap index**

`content/lore/canon-roadmap.md`:
```markdown
# Canon Roadmap

The world's answer to `docs/roadmap.md`: what is authored vs pending, and the
order the Margreave is being written. Source of truth is `content/lore/*.md`;
`content/world` + `content/server` are BUILT from it (`python -m content_build`).

## Authored (status: canon)

- **duncarrow.md** — Duncarrow (the Tallow Reach market town), the White Antlers
  shrine, the Crell secret chain, and NPCs Mera Fenn (witness), Mayor Crell
  (control), Harn Blackwood (texture). The bounded-dialogue / disposition-gate
  specimen.

## Pending (not yet authored)

- The rest of the Tallow Reach region; the elven road-peoples beyond the stub
  `faction.elves`; the seven worldbuilding topics tracked in the
  canon-architecture direction.
```

- [ ] **Step 6: Run the build and fix any validation errors**

Run: `PYTHONPATH=tools .venv/bin/python -m content_build`
Expected: exit 0, no `BUILD FAILED` output. If it reports an error, the message names the entry id + `duncarrow.md:<line>` — fix that block and re-run.

- [ ] **Step 7: Write the round-trip acceptance test**

`tools/content_build/tests/test_duncarrow.py`:
```python
"""End-to-end: the real promoted Duncarrow bible builds green and routes the
Crell secret correctly (body server-only; the id ships in the gate skeleton)."""

import json
from pathlib import Path

from content_build.__main__ import _load_world, check
from content_build.emit import build_trees

REPO = Path(__file__).resolve().parents[3]
LORE = REPO / "content" / "lore"
WORLD = REPO / "content" / "world"
SERVER = REPO / "content" / "server"


def test_duncarrow_builds_and_check_is_clean():
    assert check(LORE, WORLD, SERVER) == 0


def test_secret_body_is_server_only():
    client, server = build_trees(_load_world(LORE))
    assert "topics/crell-runs-slave-trade.json" in server
    # the secret's descriptive id ships in the gate skeleton (schema property)...
    npc = client["npcs/mayor-oswin-crell.json"]
    assert any(k["fact_id"] == "secret.crell-runs-slave-trade"
               and k["gate"] == "never" for k in npc["knows"])
    # ...but its BODY never reaches any client artifact
    blob = json.dumps(client)
    assert "elf-slaving" not in blob and "sells them into slavery" not in blob


def test_mera_never_holds_the_secret():
    client, _ = build_trees(_load_world(LORE))
    fenn = client["npcs/mera-fenn.json"]
    facts = {k["fact_id"] for k in fenn["knows"]}
    assert "secret.crell-runs-slave-trade" not in facts
    assert "fact.crells-guard-acts-alone" in facts
```

- [ ] **Step 8: Run the acceptance test**

Run: `PYTHONPATH=tools .venv/bin/python -m pytest tools/content_build/tests/test_duncarrow.py -q`
Expected: PASS (3 passed). If `test_secret_body_is_server_only` fails on the `elf-slaving`/`slavery` assertion, the secret body leaked into a client artifact — a real bug; stop and fix routing.

- [ ] **Step 9: Commit the promoted bible + built artifacts**

```bash
git add content/lore/duncarrow.md content/lore/canon-roadmap.md content/world content/server tools/content_build/tests/test_duncarrow.py
git commit -m "feat(content): promote Duncarrow; build client/server artifacts"
```

### Task 7: Client loader tolerates the new `canon/` + `topics/` dirs

**Files:**
- Modify: `client/scripts/content/content_db.gd`
- Test: `client/tests/unit/test_content_db.gd`

**Interfaces:**
- Consumes: the built `content/world/{canon,topics}/*.json` (Task 6).
- Produces: `ContentDB` gains `canon_entities: Dictionary`, `topics: Dictionary`, and `canon(id)/topic(id)/has_canon(id)/has_topic(id)` accessors. The backing var is `canon_entities` (not `canon`) because GDScript forbids a var and a method sharing a name — mirroring the existing `var locations` / `func location` pairing. Existing dirs + legacy `fenn.json` unchanged.

- [ ] **Step 1: Write the failing loader tests**

Append to `client/tests/unit/test_content_db.gd`:
```gdscript
func test_loads_canon_and_topics():
	assert_true(db.has_canon("town.duncarrow"))
	assert_true(db.has_canon("place.the-white-antlers"))
	assert_true(db.has_topic("rumor.travelers-go-missing"))


func test_topic_skeleton_has_no_body():
	var t := db.topic("secret.crell-runs-slave-trade")
	assert_false(t.has("body"))  # bodies are server-only


func test_legacy_npcs_still_load():
	assert_true(db.has_npc("fenn"))
	assert_true(db.has_npc("mera-fenn"))
```

- [ ] **Step 2: Run to verify it fails**

Run: `cd client && ./run_tests.sh -gtest=res://tests/unit/test_content_db.gd`
Expected: FAIL — `has_canon`/`has_topic` not found (or the dicts are empty).

- [ ] **Step 3: Add the two dirs and accessors to `content_db.gd`**

In `client/scripts/content/content_db.gd`, add two vars after the existing `items` var (line ~10):
```gdscript
var canon_entities: Dictionary = {}
var topics: Dictionary = {}
```

In `load_from()`, after the existing `items = _load_dir(...)` line, add:
```gdscript
	canon_entities = _load_dir(world.path_join("canon"))
	topics = _load_dir(world.path_join("topics"))
```

Add accessors next to the existing `location()/npc()/...` accessors (note the
backing var `canon_entities` — a `func canon` cannot share a name with its var):
```gdscript
func canon(id: String) -> Dictionary: return canon_entities.get(id, {})
func topic(id: String) -> Dictionary: return topics.get(id, {})
func has_canon(id: String) -> bool: return canon_entities.has(id)
func has_topic(id: String) -> bool: return topics.has(id)
```

Note: `_load_dir` already `push_error`s and skips a missing dir, so this stays safe if `canon/`/`topics/` are ever absent.

- [ ] **Step 4: Run to verify it passes**

Run: `cd client && ./run_tests.sh -gtest=res://tests/unit/test_content_db.gd`
Expected: PASS — the new tests green, existing `test_content_db` tests still green.

- [ ] **Step 5: Run the full client suite to confirm no regressions**

Run: `cd client && ./run_tests.sh`
Expected: PASS (no new failures).

- [ ] **Step 6: Commit**

```bash
git add client/scripts/content/content_db.gd client/tests/unit/test_content_db.gd
git commit -m "feat(client): ContentDB loads canon/ + topics/ built dirs"
```

### Task 8: CI gate

**Files:**
- Create: `.github/workflows/content-build.yml`

**Interfaces:**
- Consumes: the tool + committed artifacts (Tasks 1–6).
- Produces: a CI job that runs the tool tests and `--check`.

> **Note:** the repo has no CI yet. This adds a minimal GitHub Actions workflow. If the project uses a different CI provider, port these two commands (`pytest tools/content_build/tests` and `python -m content_build --check`) to it and skip this file.

- [ ] **Step 1: Write the workflow**

`.github/workflows/content-build.yml`:
```yaml
name: content-build
on:
  push:
    paths: ["content/**", "tools/content_build/**", ".github/workflows/content-build.yml"]
  pull_request:
    paths: ["content/**", "tools/content_build/**"]
jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-python@v5
        with:
          python-version: "3.12"
      - run: pip install -r tools/requirements-dev.txt
      - name: Unit tests
        run: PYTHONPATH=tools python -m pytest tools/content_build/tests -q
      - name: Content freshness + validity
        run: PYTHONPATH=tools python -m content_build --check
```

- [ ] **Step 2: Sanity-run the two CI commands locally**

Run:
```bash
PYTHONPATH=tools .venv/bin/python -m pytest tools/content_build/tests -q
PYTHONPATH=tools .venv/bin/python -m content_build --check
```
Expected: both exit 0.

- [ ] **Step 3: Commit**

```bash
git add .github/workflows/content-build.yml
git commit -m "ci: content-build tests + --check gate"
```

---

## Done criteria

- `PYTHONPATH=tools .venv/bin/python -m pytest tools/content_build/tests -q` → all green (parse, model, resolve, emit, cli, duncarrow).
- `PYTHONPATH=tools .venv/bin/python -m content_build --check` → exit 0.
- `content/lore/duncarrow.md` + `content/lore/canon-roadmap.md` exist; `candidate-town.md` is gone.
- Built `content/world/{canon,topics,npcs}` + `content/server/{npcs,topics}` committed; the Crell secret **body** appears only under `content/server/`.
- `cd client && ./run_tests.sh` → green, legacy NPCs still load.
- Then: **superpowers:finishing-a-development-branch** to smoke-test and (on the human's confirmation, per §18) merge `feature/content-build-tool` → `dev` with `--no-ff`.

## Out of scope (next cycles — do NOT build here)

- Runtime consumption: client computing gated `available_moves` from the new npc skeletons; `api` reading personas from `content/server/`; voicing Mera Fenn end to end.
- Legacy `fenn.json` migration to a bible.
- Godot export packaging (include `world/`, exclude `server/`).
- Opaque topic ids (the descriptive-slug spoiler property is inherent to the locked schema — noted, not fixed).
