# sow-tools / Crucible Agent Guide
This repo owns the **builder logic** for the migration: one Go module
(`gitea.westgate.pw/ShadowsOverWestgate/sow-tools`) producing the `crucible`
dispatcher and the `crucible-<name>` binaries (D11). Read
[`../AGENTS.md`](../AGENTS.md) (migration hub) and
[`../../KICKOFF_PROMPT.md`](../../KICKOFF_PROMPT.md) first.
## What this repo owns / does not own
Owns: build/extract/validate/compare pipeline, ERF/HAK packing, topdata 2da/tlk
compilation, wiki rendering/deploy, depot blob verify, music conversion,
changelog. Does **not** own authored game content (that is `sow-module` /
`sow-topdata` / `sow-assets-manifest`) or any production deploy authority (that
is `sow-platform`).
## Scaffold rules (Phase 5)
1. **Source is not transplanted.** The migration hard rules forbid copying the
`internal/` packages from `gitea/sow-tools` automatically. The operator
migrates them at cutover; see [`docs/migration-from-nwn-tool.md`](docs/migration-from-nwn-tool.md).
2. **Fail closed, never fake.** Unwired builders exit `70`. Do not stub a
builder to emit a placeholder artifact.
3. **Binaries are not committed.** They are CI artifacts / image layers (D19).
`/bin/`, `*.exe`, `nwn-tool`, `sow-toolkit` are gitignored.
4. **No home-dir / `NWN_ROOT` guessing.** Builders take roots explicitly via
flag or env. See [`docs/consumer-contract.md`](docs/consumer-contract.md).
5. **The registry is the command surface.** `internal/dispatch.Registry` is the
single source of truth; keep it in sync with `cmd/` and
[`docs/command-surface.md`](docs/command-surface.md). Adding a builder = a
`cmd/crucible-<name>/main.go` shim + a `Registry` entry + a doc row.
## Wiring a builder (operator cutover)
1. Migrate the relevant `internal/` package(s) from `gitea/sow-tools`.
2. Register a handler and flip the builder off the unwired path in
`internal/dispatch`.
3. Add tests; keep outputs deterministic (same input → same bytes).
4. `make check` must stay green; `make smoke` is updated to expect a wired exit.
## Commands
```bash
nix develop && make check # vet + test + shellcheck + yamllint
make build # cmd/* -> ./bin
make smoke # assert fail-closed contract
make image # crucible:<sha>
```
## Git
Never commit, branch, or push. Suggest a commit message; let the operator do it.

# sow-tools — Crucible
Crucible is the Shadows Over Westgate build/conversion/sync toolchain: one Go
module producing several small binaries plus a `crucible` dispatcher (D11). It is
the **only** repo that owns builder logic; the artifact repos (`sow-module`,
`sow-topdata`, `sow-assets-manifest`) invoke Crucible through wrapper scripts and
never embed a toolkit.
```text
Repos produce artifacts. sow-platform deploys artifacts.
Crucible is how the artifact repos turn source into artifacts.
```
## Binaries
| Binary | Dispatcher form | Owns |
| ------------------ | ------------------ | ----------------------------------------------- |
| `crucible` | — | dispatcher: `crucible <builder> [args]` |
| `crucible-depot` | `crucible depot` | content-addressed depot blob verify/move |
| `crucible-hak` | `crucible hak` | ERF/HAK pack/unpack + hak manifests |
| `crucible-module` | `crucible module` | build/extract/validate/compare the `.mod` |
| `crucible-topdata` | `crucible topdata` | compile 2da/tlk topdata + packages |
| `crucible-wiki` | `crucible wiki` | render + deploy mechanical wiki pages |
The dispatcher and the standalone shims share one registry
(`internal/dispatch`); the shims exist so consumer wrapper scripts can resolve a
single-token command. The full legacy `nwn-tool` command surface and where each
command lands is mapped in [`docs/command-surface.md`](docs/command-surface.md).
## Status (Phase 5 scaffold)
The suite **builds, vets, tests, and runs**, but every builder is **unwired**:
running one fails closed with exit `70` and never fakes an artifact. The internal
pipeline/topdata/erf/wiki/music packages from `gitea/sow-tools` are migrated by
the operator at cutover — the workspace hard rules forbid transplanting that
source automatically. See [`docs/migration-from-nwn-tool.md`](docs/migration-from-nwn-tool.md).
This matches the downstream skeletons: `sow-module` / `sow-topdata` package
scripts already fail closed until they can resolve a Crucible binary.
## Develop
Self-contained (D8) — a host with only Nix can run everything:
```bash
nix develop # Go + ffmpeg + shellcheck + yamllint + make
make check # go vet + go test + shellcheck + yamllint
make build # build every cmd/* into ./bin (gitignored)
make smoke # build + assert the fail-closed contract
make image # docker build -> crucible:<sha>
```
Binaries are **never committed** — they are CI artifacts / image layers (D19).
This retires the old habit of checking in `nwn-tool` / `sow-toolkit`.
## CI
PR-first (D7): every check runs on pull requests and on push to `main`.
- `test.yml` — vet, test, shellcheck, yamllint, binary smoke.
- `build-image.yml` — build `registry.westgate.pw/sow/crucible:<sha>`; publish
only on `main`. PRs build but never push. No mutable tags.
- `release.yml` — tag-gated binary bundles; image re-tag is wired in Phase 6.
## Consumers
How the artifact repos resolve a Crucible binary (and the `NWN_ROOT` rule) is
documented in [`docs/consumer-contract.md`](docs/consumer-contract.md).

# Crucible command surface
Crucible re-homes the single `nwn-tool` (a.k.a. `sow-toolkit`) command surface
into five builders plus a dispatcher (D11). This table maps every legacy command
to its Crucible home. It is the migration contract — keep it in sync with
`internal/dispatch.Registry`.
## Builders
| Builder | Legacy `nwn-tool` commands subsumed |
| ------------------ | ------------------------------------------------------------------------------------- |
| `crucible-module` | `build`, `build-module`, `extract`, `validate`, `compare`, `apply-hak-manifest`† |
| `crucible-topdata` | `validate-topdata`, `build-topdata`, `build-top-package`, `compare-topdata`, `convert-topdata` |
| `crucible-hak` | `build-haks`, `apply-hak-manifest` |
| `crucible-wiki` | `build-wiki`, `deploy-wiki` |
| `crucible-depot` | (new) depot blob verify/move — was shell `mc`/S3 in `sow-assets-manifest` |
`apply-hak-manifest` is HAK-list maintenance on a module; it is reachable from
both `crucible-module` and `crucible-hak`. Canonical home is `crucible-hak`.
## Folded / global commands
These legacy commands are **not** top-level builders:
- `music *` (`list-datasets`, `scan`, `build`, `credits`, `validate`, `manifest`,
`normalize`) → folds into the **module/hak build pipeline** (music BMUs are
packed into HAKs at build time). Exposed as `crucible-module music ...` /
`crucible-hak music ...` when wired. Needs `ffmpeg` at runtime.
- `config *` (`validate`, `effective`, `inspect`, `explain`, `sources`) → a
**global** concern shared by every builder; exposed as a global subcommand
group, not its own binary.
- `build-changelog` → release tooling; lands as a global `crucible changelog`
rather than a content builder.
## Global commands (implemented in the scaffold)
```text
crucible help | -h usage + builder list
crucible version | -V build version (git sha via -ldflags)
crucible list builders, one per line: name<TAB>bin<TAB>summary
```
`crucible list` is machine-readable so CI can enumerate builders without parsing
help text.
## Global flags (planned, at wiring time)
`--quiet`, `--verbose`, `--debug` (the legacy verbosity model), passed after the
builder name, e.g. `crucible topdata build-topdata --verbose`.

# Crucible consumer contract
How the artifact repos (`sow-module`, `sow-topdata`, `sow-assets-manifest`)
locate and invoke a Crucible builder. The goal: **no local-machine assumptions**
(Phase 5 exit criterion). A consumer either finds a Crucible binary or fails
closed — it never fakes an artifact.
## Resolution order (single-token command)
Each consumer wrapper resolves its builder to one executable token, in order:
1. **Explicit override**`$SOW_MODULE_BUILD` / `$SOW_TOPDATA_BUILD` /
`$CRUCIBLE` (a path or name), if set and executable. Back-compat with the
pre-Crucible skeletons.
2. **Standalone Crucible binary**`crucible-module` / `crucible-topdata` /
`crucible-hak` / `crucible-depot` on `PATH`.
3. **Legacy name**`sow-module-build` / `sow-topdata-build` on `PATH`
(pre-D11; kept so nothing breaks during cutover).
If none resolve, the wrapper exits non-zero with a Phase 5 message. The
`crucible` dispatcher (`crucible module …`) is for humans and CI introspection;
wrappers prefer the single-token `crucible-<name>` shim so `"$builder" args`
quoting stays correct.
## In CI (preferred)
Run the consumer job inside the pinned image and the binaries are on `PATH`:
```yaml
container:
image: registry.westgate.pw/sow/crucible:<sha> # pinned, immutable
```
No host install, no `$HOME` layout, no developer machine assumptions.
## `NWN_ROOT` rule
Crucible **never guesses `NWN_ROOT` from `$HOME`** (this was a deploy-notes
pain point). The NWN install/data root is passed explicitly:
- env `NWN_ROOT=/path/to/nwn`, or
- flag `--nwn-root /path/to/nwn`.
A builder that needs `NWN_ROOT` and receives neither must fail closed with a
clear message, not fall back to a home-directory default.
## Determinism
Same inputs → identical output bytes. Consumers may checksum artifacts across
runs; non-determinism is a builder bug.

# Migrating from `nwn-tool` to Crucible (operator cutover)
The legacy toolchain lives at `gitea/sow-tools` as a single `nwn-tool` binary
(entry `cmd/nwn-tool`, logic under `internal/`). This repo is the Crucible
rewrite. Per the migration hard rules, the `internal/` source is **not**
transplanted automatically — the operator migrates it. This is the checklist.
## Why a clean scaffold first
- The hard rules forbid copying old-repo source into the migration tree
(`build from scratch; reference, don't transplant`).
- The downstream skeletons (`sow-module`, `sow-topdata`) already fail closed
until they can resolve a Crucible binary; the scaffold satisfies that contract
without faking artifacts.
- The scaffold pins the **shape** (module path, dispatcher, multi-binary layout,
container, CI) so the migrated logic drops into a stable frame.
## Cutover steps
1. **Move the internal packages.** Bring `internal/{app,pipeline,project,erf,
gff,topdata,music,changelog,validator}` from `gitea/sow-tools` into this repo.
Re-home `internal/app` command wiring behind `internal/dispatch` instead of
the old flag parser in `cmd/nwn-tool`.
2. **Restore dependencies.** Add `golang.org/x/text` and `gopkg.in/yaml.v3` back
to `go.mod`; commit the resulting `go.sum`. (`docker/Dockerfile` already
tolerates an absent `go.sum` for the scaffold; it will be present after this.)
3. **Wire each builder.** In `internal/dispatch`, register a handler per builder
and remove it from the unwired fail-closed path. Map the legacy commands per
[`command-surface.md`](command-surface.md).
4. **Kill the home-dir / `NWN_ROOT` defaulting.** Honor only explicit
env/flag roots per [`consumer-contract.md`](consumer-contract.md).
5. **Drop the committed binary.** Delete `nwn-tool` / `tools/sow-toolkit` from
the source tree; `.gitignore` already excludes them. Binaries become CI
artifacts and image layers only.
6. **Carry the determinism test.** Port
`TestBuildNativeKeepsGeneratedIDsStableAcrossRepeatedBuilds` and keep it green.
7. **Runtime base for music.** If music conversion is wired, switch the final
Docker stage from `distroless/static` to a debian-slim base that includes
`ffmpeg`.
8. **Update `make smoke`.** Once a builder is wired, change the smoke
expectation for it from exit `70` to a real success path.
## Wrapper contract carried over
Consumer repos keep the `SCRIPT_WRAPPER_CONTRACT` resolution behavior, now
pointed at Crucible binaries — see [`consumer-contract.md`](consumer-contract.md).
The old `SOW_TOOLS_DEV_BINARY` dev override maps to `$CRUCIBLE` /
`$SOW_MODULE_BUILD` / `$SOW_TOPDATA_BUILD`.
