PluginManifest gains `codeless` (additive, buf-breaking clean): an artifact
with NO plugin.wasm that the host runs entirely. `ninja plugin build`
classifies by repo shape — no Go source → codeless (manifest synthesized from
plugin.mod + optional manifest.yaml: theme presets, fonts, settings schema,
master pages, CSS, icon packs, deps); Go source → wasm as always. New
`--codeless` flag asserts the expectation.
Both artifact kinds now pack the declarative dirs: blocks/ (the cms
blocks.yaml manifest-FS layout — definition-backed blocks), templates/, and
seed/ (seed.json: settings/media/pages/menu items, applied host-side via the
WO-WZ-019 provisioner). The packer structurally validates blocks.yaml and
seed.json (schema JSON validity, file presence, traversal safety); full
semantic validation stays host-side at install.
`ninja plugin verify`: plugin.wasm is required exactly when NOT codeless; a
codeless manifest declaring any computing hook (http/jobs/load/unload/media/
RAG/tags/filters/services/guest blocks/data_dir) is rejected —
CodelessHookViolation mirrors the cms reader check (lockstep duplication).

pongo2 stays host-side and is never compiled into a guest; plugins render
templates by handing the host a {template, data} pair, and the host calls
back into the free guest instance for plugin-declared tags/filters.
ABI (additive, buf-breaking clean):
- RenderBlockResponse gains a `powered` PoweredBlock{template, data_json};
a block returns EITHER html OR powered.
- New hooks HOOK_RENDER_TAG (10) / HOOK_APPLY_FILTER (11) with
RenderTag{Request,Response} and ApplyFilter{Request,Response}.
- PluginManifest gains repeated declared_tags / declared_filters (31/32).
Guest SDK (core/blocks, core/plugin/wasmguest):
- blocks.PoweredBlock(template, data) / DecodePoweredBlock: NUL-sentinel
marker so BlockFunc's string signature is unchanged (smallest additive
change — no ripple to existing blocks or the host guest-side).
- blocks.RegisterTag / RegisterFilter (+ RenderContext = context.Context)
write a package-level registry; runRegister resets it per registration
for deterministic DESCRIBE + dispatch.
- DESCRIBE emits declared_tags/filters; dispatch handles RENDER_TAG /
APPLY_FILTER (fn errors → response.error; panics → AbiError INTERNAL,
instance stays callable).
Docs: core/docs/wasm-abi.md gains the render-as-a-host-capability model,
the powered-block flow (re-entrancy-free), the plugin API, and the
HOST-SIDE CONTRACT the cms phase implements.
Tests: unit round-trips for powered/RENDER_TAG/APPLY_FILTER (dispatch +
error + unknown + panic + per-guest registry isolation) plus a real
wazero round-trip through the compiled fixture module. Verified no
guest-reachable package imports pongo2 (go list -deps on the wasip1
fixture build is clean).

`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.
