`ninja plugin build` compiles a plugin to reactor-mode wasip1 wasm (Go >= 1.24 enforced), extracts manifest.pb by driving one HOOK_DESCRIBE over wazero with failing host stubs, and packs a tar.zst .bnp (plugin.wasm, plugin.mod, manifest.pb + migrations/schemas/assets/web-dist when present) with a summary table. A describe-time capability call (e.g. db.* from Register) fails with an actionable error naming the offending method. `ninja plugin verify` re-runs the CMS reader's layout/name/abi/path-safety/size checks standalone (deliberate duplication of cms backend/plugin/bnp/reader.go; kept in lockstep by WO-WZ-010). ABI riders (additive; buf breaking clean): - ABI_ERROR_CODE_TX_EXPIRED enum value + bnwasm guest mapping to a new bnwasm.ErrTxExpired sentinel (retryable tx expiry, distinct from real faults); the cms dbexec side adopts the emit separately. - PluginManifest.data_dir bool + a first-class `data_dir` key on the plugin.mod parser (so writeMod's struct round-trip can't drop it); `plugin build` stamps it from plugin.mod into the manifest. Docs: wasm-abi.md gains a Building & packing section, the error-code table row, the manifest data_dir mapping, and the plugin.mod reference. Tests: CLI e2e builds the WZ-002 fixture → verify + manifest block keys; a capfixture proves the actionable describe-time error; verify rejects each malformed class; bnwasm TX_EXPIRED classification.
