Dynamic families added to the ABI + guest SDK:
- provisioner.* (14 methods, 1:1 plugin.Provisioner): wasm provisioning was
silently dead (RegisterWithProvisioner got a noopProvisioner and the cms
loader ignored has_provisioner). Now a LOAD-TIME capability via the new
CoreServices.Provisioner field; EnsureEmbed rejects RenderFunc-only embeds.
- content.* writes (content.Author + CoreServices.ContentAuthor):
create_page, set_page_blocks, publish_page, set_page_seo, upsert_post.
- settings.update_plugin_settings (settings.Updater grows the method).
- bridge.invoke + plugin.BridgeInvokable: opaque-payload cross-plugin calls
(typed GetService still returns nil across the sandbox by design).
- jobs.progress: HOOK_JOB handlers' progress() now crosses (was discarded).
New host→guest hooks: HOOK_AI_TOOL_CALL (executes recorded ai.ToolDefinition
handlers — registers tools in Register so every pooled instance has them),
HOOK_BRIDGE_CALL, HOOK_DIRECTORY_PANEL_SECTION, HOOK_DIRECTORY_PIN_DECORATOR.
The ai/bridge stubs now record handlers/values locally in addition to
forwarding names.
buf breaking clean (additive within ABI major 1); golden round-trips added
for the new families (cms host replays the same goldens).

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).

Block/template render funcs receive only ctx+content over the ABI, no
services. Load runs on a single pooled instance, so a DB-backed block on
any other pooled instance had a nil pool. HostServices() exposes the
CoreServices bound at _initialize on every instance (live db.* Pool +
capability stubs) so render funcs resolve their pool per-instance. Zero
value in native builds (Serve never called); callers nil-check Pool.
Enables the symposium wasm port (WO-WZ-012).

Bind the db.* driver over the same transport as the capability stubs so
deps.Pool keeps working for plugin sqlc code:
- dispatch.go: g.services.Pool = bnwasm.NewPool(capTransport) (nil on
native/DESCRIBE → fails cleanly, matching the caps stubs).
- hostcalls.go (wasip1): also bind the "bnwasm" database/sql driver's
process-global transport to CallHost.
- docs/wasm-abi.md: document the implemented guest driver + pgx-primary
rationale under the Pool disposition.

Every CoreServices interface (core/plugin/deps.go) now has a guest-side stub
that marshals to the WO-WZ-001 capability messages and dispatches through the
generic host_call transport, so plugin service code compiles and runs
unchanged against content.Content, settings.Settings, plugin.PluginBridge, etc.
- core/plugin/wasmguest/caps/: one file per family (17 families, 38 methods),
a var _ <iface> = (*stub)(nil) compile proof each, and NewCoreServices(call)
assembling them. The transport is injected (CallFunc) so marshaling is
natively testable; the wasm shim binds it to CallHost, DESCRIBE probes pass
nil (capability calls fail cleanly instead of nil-panicking).
- Error mapping wraps AbiError with <family>.<method> context and maps
DEADLINE_EXCEEDED onto context.DeadlineExceeded.
- RAGService.RegisterContentFetcher stays guest-side (RAGStub) for
HOOK_RAG_FETCH dispatch; Query/OnContentChanged marshal out. dispatch.go and
describe.go now source fetchers from the caps RAG stub.
- caps_roundtrip_test.go: fake transport + 76 deterministic golden payloads
(family_method_{req,resp}.pb) covering 100% of families, plus error-mapping,
deadline, nil-transport, and guest-side-fetcher tests. WO-WZ-006 replays the
same goldens to prevent host/guest drift.
- Acceptance: testdata/fixture Load hook calls deps.Content/Settings/Bridge
unchanged (compiles for wasip1); caps_wasmhost_test.go drives it end-to-end
through a real wazero module + fake host_call table.
- Disposition table in docs/wasm-abi.md: every member stub | host-side
(Pool, Interceptors, AppURL/MediaPath, CoreServiceBindings host-side).

The wasip1 half of the ABI: bn_alloc/bn_invoke/bn_free exports with a
live-pin map so the GC never frees host-visible buffers, the generic
`blockninja.host_call` import (single import decided over per-family
symbols; recorded in wasm-abi.md), and a dispatch table adapting an
unmodified plugin.PluginRegistration to all nine v1 hooks. Panics inside
plugin hooks come back as ABI_ERROR_CODE_INTERNAL — the instance stays
callable; traps stay reserved for runtime corruption.
DESCRIBE builds the PluginManifest from the registration's static funcs
plus a capture-only Register pass (block metas via the same
PluginBlockRegistry prefixing the .so loader applies, template/system/
page-template/email-wrapper keys), probes JobHandlers/ServiceHandlers/
Load with capture-only services for job types, RBAC roles, core-service
bindings, and RAG fetcher types. RenderContext values are rehydrated
through the exact core/blocks context keys, so existing block code
reading from ctx works unchanged.
Plugins build in REACTOR mode (go build -buildmode=c-shared): init()
calls wasmguest.Serve (non-blocking), main is never called, and the host
runs _initialize before any bn_invoke. Command mode deadlocks or exits
(verified against wazero v1.12.0) — documented prominently in
wasm-abi.md, which also now reconciles the import module namespace to
`blockninja` and requires bn_alloc'd buffers on both directions.
Dispatch/describe/context logic is buildable on every GOOS; only
exports.go and hostcalls.go carry the wasip1 tag. dispatch_test.go
covers describe, hook routing, envelope mismatch, decode failures,
template-override resolution, panic recovery, and lifecycle hooks
natively.
