feat(ci): prune release assets outside the newest two tags (#52)
Gitea has no release-asset retention, so every v* tag kept its full
cross-platform binary set forever — 31 tags had accumulated 1.8 GB on the
production host disk. Nothing consumes an old asset: CI takes the Crucible
binary from the Nix flake, and every deleted file is reproducible from its tag.

scripts/prune-release-assets.sh lists every release page, sorts by creation
date, skips the newest two published releases, and deletes the remaining
releases' attachments. Two rather than one so a release in flight never leaves
the previous download broken. Drafts never consume a keep slot. Releases, tags,
source archives and release notes are untouched.

Nothing is excluded — SHA256SUMS and the wrappers go with the binaries: the
checksums are only meaningful next to the files they cover, and the consumer
drift-check reads the wrappers from the latest release, which stays complete.

The step is best-effort: a stale asset is cheaper than a blocked publish, so
API failures warn and the step carries continue-on-error.

# 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 (cutover performed)
The internal `app`/`pipeline`/`project`/`erf`/`gff`/`topdata`/`changelog`/
`validator` packages from `gitea/sow-tools` have been migrated into this tree, and
the `module`, `topdata`, `hak`, and `wiki` builders now **delegate to the migrated
`nwn-tool` command surface** (mapped in
[`docs/command-surface.md`](docs/command-surface.md)). `config` and `changelog`
are global commands on the dispatcher. `depot` has no migrated logic yet, so it
keeps the fail-closed path: exit `70`, never a faked artifact.
See [`docs/migration-from-nwn-tool.md`](docs/migration-from-nwn-tool.md) for what
was done and what remains (the consumer `--manifest/--source/--out` flag contract
is the open Phase-6 item).
## Quick start (no Nix)
Teammates without Nix don't build anything — they run the bootstrap wrapper,
which downloads the latest released `crucible` for your OS and runs it:
```bash
./crucible # interactive menu (pick a command)
./crucible module build
./crucible topdata validate
```
Windows (PowerShell):
```powershell
.\crucible.ps1 module build
```
The binary is cached under `~/.cache/crucible/<version>/` (`%LOCALAPPDATA%\crucible`
on Windows); `--repo-local` caches inside the repo instead. Private releases:
set `CRUCIBLE_TOKEN` or write the token to `~/.config/crucible/token`.
## Develop
Self-contained (D8) — a host with only Nix can run everything:
```bash
nix develop # Go + 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
```
Binaries are **never committed** — they are CI artifacts (D19).
This retires the old habit of checking in `nwn-tool` / `sow-toolkit`.
## CI
PR-first (D7): checks run once on pull requests; the only publish event is a
`v*` tag (see `runbooks/ci-trigger-standard.md` in sow-docs,
https://git.westgate.pw/ShadowsOverWestgate/sow-docs).
- `ci.yml` — vet, test, shellcheck, yamllint, binary smoke, and cross-build all
targets once per pull request.
- `build-binaries.yml` — on a `v*` tag, cross-build and upload the binaries,
`SHA256SUMS`, and the wrappers to the Gitea release, then delete the assets
of every release except the newest two — Gitea keeps them forever otherwise,
and every binary is reproducible from its tag.
- `sync-wrappers.yml` — on a `main` push that touches `wrappers/`, auto-PR the
canonical wrappers to the consumer repos in `wrappers/consumers.txt`.
Consumer drift checks run after those PRs merge to `main`, not on the PRs
themselves, to avoid recursive cross-repo checks.
## Consumers
How the artifact repos resolve a Crucible binary is
documented in [`docs/consumer-contract.md`](docs/consumer-contract.md).
