archvillainette ed6945d308 Adopt workspace-wide agent standards; retire sow-docs (#51)
Part of the workspace-wide standards rollout. Establishes where work lives (issues vs ADRs vs standing law), scaffolds `docs/agents/` for the engineering skills, and adopts ADR-0001 locally. See `sow-platform` ADR-0021 for the `sow-docs` retirement.Reviewed-on: #51

# ADR-0003: Crucible binary contract: standalone shims, fail-closed scaffold, no committed binaries
- **Status:** Accepted
- **Date:** 2026-06-11
- **Migrated from:** `sow-docs` `07-decisions-log.md` entry **D19**, on the
retirement of `sow-docs`. Content is the original decision, unchanged.
- **Decision:** Phase 5 builds `migration/sow-tools` (Crucible, D11) as a
multi-binary Go scaffold:
- One `crucible` dispatcher plus standalone `crucible-{depot,hak,module,topdata,wiki}`
binaries sharing one registry (`internal/dispatch`). The dispatcher is for
humans/CI; the **standalone shims are canonical for consumers** so wrapper
scripts resolve a single-token command and `"$builder" args` quoting stays
correct.
- Consumer resolution order: explicit env override
(`$SOW_MODULE_BUILD`/`$SOW_TOPDATA_BUILD`/`$CRUCIBLE`) → `crucible-<name>`
legacy `sow-<name>-build`. CI runs inside the pinned `crucible:<sha>` image.
- Every builder is **unwired** in the scaffold and fails closed (exit 70);
it never fakes an artifact. The `internal/` logic is migrated from
`gitea/sow-tools` by the operator at cutover (hard rule: no source
transplant by tooling).
- **Binaries are never committed** — they are CI artifacts / image layers.
Retires the committed `nwn-tool` / `tools/sow-toolkit`.
- Builders take `NWN_ROOT` only via explicit env/flag; no `$HOME` defaulting.
- **Rationale:** Locks the command surface, container, and CI shape so migrated
logic drops into a stable frame; aligns the three artifact repos onto one
Crucible contract while keeping back-compat with the pre-D11 skeletons.
- **Image name:** `registry.westgate.pw/deployment/crucible:<git-sha>` (the bare
`crucible:<sha>` is the local/dev tag).
