…sionHost lifecycle
Phase P2, first slice (workstream B core, self-contained crate). Wires
nothing into the production dispatcher yet — that cutover (P2b) moves the
production caller and deletes the old path in the same PR.
- host_api: the ToolAdapter ABI (one adapter per extension, one `invoke`
method), ToolCall/ToolResult/ToolError/ToolPorts, and the RestrictedEgress
+ ScopedToolState host ports. ToolResult is behavior-only output; resource
usage/receipt/events/audit stay host-side in the loader/dispatcher pipeline.
- product_adapters: the generic ChannelAdapter trait (activate/cleanup/
inbound/deliver/list_targets) with normalized DTOs (VerifiedInbound,
InboundOutcome, NormalizedInboundMessage with the ≤4 KiB opaque
reply_context, OutboundEnvelope, DeliveryReport, AttachmentRef as a
reference not bytes), alongside the retiring ProductAdapter.
- New crate ironclaw_extension_host (products layer; deps host_api /
extensions / product_adapters only — no host_runtime, no composition):
- state.rs: the two standard state machines — one InstallationState enum
(Installed/Activating/Active/Deactivating/Removing/RemovalPending/Removed)
with deterministic transient resume targets, and one AuthAccountState
enum; both wire forms pinned.
- entrypoint.rs: ExtensionEntrypoint (side-effect-free, port-free bind) +
ExtensionBindings + the binding rule (declared surfaces must bind,
nothing undeclared may, auth never binds).
- active.rs: the immutable ActiveSnapshot (Arc swap, generations) with
capability-id and route-suffix resolver views and global conflict
detection.
- lifecycle.rs: ExtensionHost — the only writer of installation state and
the snapshot. Install/activate/deactivate/remove/restore under one async
mutex; activation runs channel.activate() and publishes exactly one
generation on success (nothing on failure); the fixed removal order
(unpublish → drain → channel.cleanup() → auth revoke/grant delete →
config/identity delete) with RemovalPending retry; startup restore that
resumes Active generations and skips invalid extensions. Auth revoke,
integration-state deletion, drain, and egress are injected ports so the
crate stays generic; the host owns only the order. Redacts hook errors
before persisting.
- store.rs: the InstallationRecordStore persistence port (carries the
resolved contract so restore never needs the package source) + an
in-memory impl. loaders/mod.rs: the ExtensionLoader port composition
dispatches by runtime kind.
- test_support.rs (feature-gated): resolved-manifest fixtures + scripted
tool/channel adapters, loader, removal hooks, drain, egress.
- 20 tests: binding rule, both state machines, and the lifecycle contract
(LIFE-1/2/5/6/7/8/9/11/12-context/14/15/16). The specificity scanner now
treats test_support modules as test code (fixtures may name concrete
products; overview §8), which also retired three now-covered allowlist
entries.
Checklist: LIFE-1/2/5/6/7/8/9/11/14/15/16 checked with named evidence; REC-2/
REC-3 checked at the store tier; LIFE-12 and AUTH-9 partially advanced with
the P3/P2b remainder noted inline.

Code Review
This pull request introduces the ironclaw_extension_host crate, implementing the core extension lifecycle host, active snapshot management, loaders, and resolvers for IronClaw Reborn, alongside the ToolAdapter and ChannelAdapter contracts. The review feedback identifies several critical correctness, robustness, and security issues that must be addressed: dynamic MCP tools will fail to resolve as they are not registered in the snapshot; state machine transition rules are defined but not enforced in lifecycle methods; removal hooks lack deadlines and could block the global lifecycle lock indefinitely; a single snapshot conflict during startup restore can brick the entire service boot; interrupted deactivations can incorrectly resurrect extensions on startup; and NormalizedInboundMessage validation lacks size bounds on text and attachments, posing OOM and database risks.
Important
The consumer version of Gemini Code Assist on GitHub is being sunset. Starting June 18, 2026, new organization installations will be blocked, and all code review activity will officially cease on July 17, 2026.

Correctness Issue: MCP Tools Resolution Failure
For MCP extensions, tools are discovered dynamically at load time (during load), meaning they are not present in the static resolved.tools list of the manifest.
Because ActiveSnapshot::build only populates capability_owner from extension.resolved.tools (lines 71-80), dynamically discovered MCP tools will never be registered in capability_owner. Consequently, resolve_tool will return None for any MCP tool call, breaking MCP tool execution entirely.
Recommendation:
Consider allowing MCP extensions to register their namespace prefix in ActiveSnapshot so that resolve_tool can fall back to routing by namespace prefix if an exact match in capability_owner is not found, or update the snapshot building process to support dynamically discovered capabilities.

Correctness Issue: State Machine Transitions Not Enforced
The state transition rules (can_transition_to) and the corresponding error variant LifecycleError::IllegalTransition are defined but never actually enforced or constructed in any of the lifecycle methods (activate, deactivate, remove, or install). This allows illegal transitions to proceed silently, leading to split-brain states and potential corruption.
Recommendation:
Enforce transition checks at the beginning of each lifecycle method.
let record = self.require_installed(extension_id).await?;
if !record.state.can_transition_to(InstallationState::Activating) {
return Err(LifecycleError::IllegalTransition {
extension_id: extension_id.to_string(),

Efficiency & Robustness Issue: Missing Deadlines on Removal Hooks
Unlike step 3 (channel.cleanup()), steps 4 (revoke_and_delete_grants) and 5 (delete_integration_state) are not wrapped in with_deadline.
Because these hooks can perform slow or blocking operations (such as remote network calls to revoke OAuth tokens), a hanging or slow hook will block the global lifecycle_lock Mutex indefinitely. Since this mutex serializes all lifecycle operations, a single hanging removal hook will brick the entire ExtensionHost for all other extensions.
Recommendation:
Wrap both calls in with_deadline using self.deps.hook_deadline to ensure they are bounded and cannot block the host indefinitely.

Robustness Issue: Single Conflict Bricks Startup Restore
If there is a duplicate capability ID or route suffix conflict among the restored extensions, ActiveSnapshot::build will return a SnapshotConflict error, causing restore_at_startup to fail entirely. This means a single conflicting or corrupted extension record will prevent the entire startup restore process from succeeding, bricking the service boot.
Recommendation:
Build the snapshot incrementally or check conflicts using would_conflict for each candidate extension. If a conflict is detected, skip only the conflicting extension, persist its state as Installed with the conflict error, and continue restoring the remaining valid extensions.

Correctness & Logic Issue: Deactivating Resume Target Resurrects Extensions
When a crash occurs during deactivation, resume_target resolves Deactivating to Active. However, restore_at_startup does not actually re-run the deactivation process; it simply restores and publishes the extension as Active. This resurrects extensions that the user explicitly requested to deactivate.
Furthermore, for Removing, it resolves to Removing but restore_at_startup simply skips it without re-driving the removal, leaving the record permanently stuck in Removing state.
Recommendation:
- Change the resume target for
DeactivatingtoInstalledto safely complete the deactivation on startup. - Clarify or implement the automatic re-drive mechanism for
Removingstates during startup.

Security & Robustness Issue: Missing Size Bounds on Untrusted Message Fields
While validate correctly enforces a 4 KiB limit on reply_context, it does not enforce any bounds on text length or the number of attachments in NormalizedInboundMessage.
Since the adapter is considered untrusted for size, a buggy or malicious adapter could return an extremely large text string or an excessive number of attachments, leading to memory exhaustion (OOM) or database write failures in the host workflow.
Recommendation:
Enforce reasonable maximum limits on text length (e.g., 64 KiB) and attachments count in validate.
impl NormalizedInboundMessage {
/// Validate host-enforceable bounds on a normalized message before it
/// enters the workflow (the adapter is untrusted for size).
pub fn validate(&self) -> Result<(), ChannelError> {
if let Some(context) = &self.reply_context
&& context.len() > MAX_REPLY_CONTEXT_BYTES
{
return Err(ChannelError::Parse {
reason: "reply_context exceeds the 4 KiB bound".to_string(),

}Workstream C, first slice: the dispatcher resolves a prebound adapter by
capability id and the per-invocation package/runtime-kind selection is
deleted (TOOL-1/TOOL-2).
- ironclaw_dispatcher: `ToolResolver` port (resolve(capability_id) →
ResolvedCapability{provider, runtime, adapter}), `BoundCapabilityAdapter`
with per-invocation-only inputs, and `ChainToolResolver`. The registry
snapshot / get_capability / get_extension / runtime-mismatch /
adapter-map selection is gone; the crate no longer depends on
ironclaw_extensions or ironclaw_filesystem at all, which also retires
the dispatcher→extensions layer-matrix exception the kernel
consolidation had scheduled. Dispatch events, best-effort sink
semantics, redaction, and the resolution-failure reservation-release
guard are unchanged.
- ironclaw_host_runtime: the four runtime lanes become host-private
(RuntimeAdapter moved in-crate); new `RegistryLaneToolResolver`
prebinds every registry capability to its lane per registry
generation (SharedExtensionRegistry::version-cached map, rebuilt on
publish/unpublish). The dispatcher-era selection failures —
UnknownProvider, RuntimeMismatch, MissingRuntimeBackend — are
preserved as error bindings that release a prepared reservation
before failing, keeping the error surface intact.
- TOOL-3 proven at the callers: capability-host × dispatcher integration
(invoke, approval block/resume, wrong-user and expired-lease
rejections), host-runtime vertical slice (obligations fail before
dispatch; resources + events), rewritten dispatcher contract/event
suites at the resolver seam, 9 real-wasmtime lane tests, and the full
composition suite (1416 lib tests). One documented event delta: a
missing-backend failure now emits `runtime_selected` before
`dispatch_failed` — selection succeeded when the binding was built;
the backend is what is missing.
Checklist: TOOL-1, TOOL-2, TOOL-3 checked with named evidence. The
active-snapshot resolver for ExtensionHost-activated extensions chains
in with the composition cutover (next commit).

…dispatch Workstream B's production composition: the P2a contracts get their first production implementations and activated-extension dispatch cuts over from the registry-lane resolver to the extension host's active snapshot. - ironclaw_host_runtime: `ExtensionLaneToolBinder` — the narrow sanctioned factory that prebinds one package to its runtime lane as a behavior-only `ToolAdapter` (routes internally by capability id; the lane keeps its reservation-settlement legs; the auth-gate payload crosses the ABI intact). `HostRuntimeServices` gains a late-installed extension-resolver slot: when composition sets it, the dispatch chain becomes [snapshot resolver → registry lane] and the registry lane restricts to the synthetic `builtin` provider — activated extension capabilities must resolve from the snapshot, with no fallback (cutover, not a parallel path). - ironclaw_extension_host: `SnapshotToolResolver` + the dispatch-side wrapper over resolved `ToolAdapter` bindings (forwards the prepared reservation verbatim; re-measures output bytes; maps `ToolError` onto the lane-shaped dispatch categories); a lock-free `SnapshotWatch` mirror of the published generation; `LoadedExtension` so discovery-owning loaders can publish an effective contract; `NativeExtensionFactory` (the binary assembles these — composition never links a concrete extension crate); reserved-capability conflicts (an extension declaring a host built-in id fails activation, TOOL-10's activation leg). - ironclaw_reborn_composition: `CompositionExtensionLoader` dispatches by resolved runtime kind — binary-assembled native factories (reservation settlement decorated host-side), the first-party registry bridge, and the wasm/mcp/script lane binder; a channel-declaring extension whose serve graph is still host-owned binds the transitional no-route `HostServedChannelBridge` until P4/P5. `build_local_runtime` constructs the host after the lanes are fully configured, hydrates it from the facade's durable installation state, attaches it to the lifecycle facade, and installs the snapshot resolver. The facade drives the host at its choke points: activation commit (with unwind compensation — an unmirrored activation would be undispatchable) and removal unpublish. The facade remains the durable-lifecycle owner in P2b; durable seven-state ownership and the host-owned removal order migrate in P6. - `RebornBuildInput::with_native_extension_factories` threads the binary-assembled factory set (empty in production until P6; integration tests register the invented-vendor fixture factory). Proven: extension_host 23 (snapshot resolution across deactivation swaps, in-flight binding survival, auth-gate mapping, reserved-id conflict), host_runtime 311 incl. the binder pins (route-by-id, undeclared-capability, missing-lane bind error, builtin allowlist restriction), composition lib 1416, architecture suite green (the specificity scanner caught and forced generic wording in this commit's own comments).

Fixes the pre-existing bug where hosted-MCP discovery through the runtime-dispatched activation path never worked: discovery runs at activation, outside the dispatch obligation pipeline, so nothing staged the connection-template capability's network policy or product-auth credential under the discovery scope — `tools/list` always failed transient and activation silently fell back to the bundled manifest with zero model-visible tools (masked under manifest v2 by the placeholder-tool fallback; pinned honestly in P1). - ironclaw_host_runtime: `ProductAuthProviderRuntimePorts` gains the credential-account resolver and the network-policy store, with two narrow staging entry points for host-driven calls that bypass the dispatch pipeline: `stage_credential_requirement_once` (secret-handle and product-auth-account sources, same resolver and AuthRequired classification as the obligation lane) and `stage_network_policy_once`. - ironclaw_reborn_composition: activation stages the template capability's declared credentials plus a server-host-only network policy under the discovery scope before `tools/list`. Best-effort by design: a staging failure leaves exactly the pre-fix fallback-to-bundled behavior; a successful stage gives discovery the same injected authority a dispatched invocation carries. The ports attach late (with the generic host) because the early handle predates the credential-account resolver wiring. - The P1 truth-pin flips: `local_dev_extension_activate_hosted_mcp_ stages_discovery_and_publishes_tools` drives the dispatched activation with a scripted vendor transport UNDER the real host egress pipeline and proves the discovered tool publishes model-visible AND that every discovery call (initialize → notifications/initialized → tools/list) carried the staged credential on the wire.

…napshot
The integration harness's direct registry publication
(`publish_bundled_extension_for_test`) now also mirrors the package into
the generic extension host — the twin of the production activation choke
point — because extension dispatch resolves from the active snapshot and a
registry-only publish would be undispatchable. In-code fixture packages
with no catalog entry (the visibility probe) supply their resolved
contract explicitly; the composition loader falls back to a
trust-derived manifest source when no durable record exists (test-seam
only; production activations always install a record first).
Proven: reborn_integration_{secret_injection,web_access,
extension_visibility,tool_disclosure,mcp,durable,wiring_parity} and
reborn_group_extensions green — github WASM dispatch (with credential
injection recorded on the wire) now flows snapshot-first through the
chain with the registry lane restricted to built-ins.

- tests/integration/extension_runtime.rs:
- acme_fixture_lifecycle_dispatches_from_the_active_snapshot — the
invented-vendor fixture drives install → activate → dispatch →
remove through model tool calls against the REAL pipeline: the
facade mirrors activation into the generic host, the fixture's
`first_party` native factory (assembled through the same
`RebornBuildInput` seam the binary uses) binds its adapters, input
schema validation runs off the fixture's real schema files, and the
tool dispatches FROM THE ACTIVE SNAPSHOT (the registry lane is
builtin-restricted, so there is no other way it can resolve).

handle lives on group storage). Provisioning failure FAILS the test —

backend matrix gains the Postgres case.

recorder retained through it.

`ProductAdapterRuntimeEntry` / `list_enabled_product_adapter_entries` was never the production path (the audit's finding) and the P2 cutover makes the active snapshot the dispatch-time source of truth — delete the projection, its read-path validation twin (write-path validation stays pinned in ironclaw_extensions), and rewrite the registry contract tests against the surviving section-projection and store surfaces.

…eature The libsql-only clippy lane (--no-default-features --features libsql) has been red since the StorageMode::Postgres matrix landed: deadpool_postgres/tokio_postgres are postgres-feature-optional deps, but the testcontainer path in tests/integration/support/builder.rs referenced them unconditionally. PR CI runs the all-features lane only, so this was a latent merge-queue breaker for the whole runtime train. cfg-split match arms keep StorageMode::Postgres compiling on every lane; the not(postgres) arm hard-errors (a Postgres skip stays a failure per REL-3), and the variant/helpers gate cleanly.

…te machine (reconcile main) (#6116) * feat(extensions): capability-surface vocabulary and manifest projection Introduce CapabilitySurfaceKind (tool/channel/auth + reserved trigger/file) in ironclaw_host_api and derive an order-stable capability-surface projection on ExtensionManifestV2: one tool surface per capability declaration, contract-projected section surfaces (ironclaw.product_adapter/v1 external_channel sections project the channel surface; host-native web/cli/synchronous_api sections project none), and one auth surface per distinct product-auth provider with OAuth scopes unioned. Host API contracts projecting tool/auth section surfaces fail closed - those kinds have dedicated declaration paths. The extension is the top-level product object; surfaces answer "which faces of this extension can be enabled?" without a separate channel registry and without runtime kind leaking into product taxonomy (NEA-25, stack PR 1 of unified extension surfaces). Contract: docs/reborn/contracts/extensions.md "Capability surfaces" names the pinned tests (manifest_v2_contract.rs surface block; manifest_ingestion.rs projection through the real adapter contract). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * refactor(extensions)!: complete manifest v2 cutover - host_api contracts everywhere Every manifest now declares its sections through [[host_api]] contracts; the legacy top-level [[capabilities]] form is rejected for every source, host-bundled exactly as installed. All 10 remaining legacy first-party manifests (gmail, google-calendar/docs/drive/sheets/slides, nearai-mcp, notion-mcp, slack, web-access) move onto the ironclaw.capability_provider/v1 section form. One parse entry point remains: ExtensionManifestV2::parse(input, source, catalog, contracts). The contract-free record constructor, the optional- contracts variant, and contract-free ExtensionDiscovery::discover are deleted, along with LegacyTopLevelCapabilitiesForInstalledSource. Host API contracts now raise a typed HostApiSectionError: in-crate contracts (capability provider) preserve precise ManifestV2Error variants (DuplicateEffect, UnknownHostPort, CapabilityIdNotPrefixed, ...) instead of string-flattening them - previously only the deleted legacy path reported typed errors. Domain crates keep redacted reason strings wrapped as HostApiSectionRejected. Production TOML surgery (NEAR AI endpoint audience rewrite) and the shared test fixture converters (legacy_capability_fixture_to_v2 in the dispatcher and host_runtime test support) now emit the host_api form. Contract: docs/reborn/contracts/extensions.md "Cutover (complete)" + converted examples. NEA-25 stack PR 2; no persisted-state impact (installed manifests already could not use the legacy form). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * refactor(reborn)!: extension-surface discovery replaces the connectable-channels rail Channel discovery is now extension-surface data, not a parallel registry. RebornExtensionInfo carries `surfaces` - a tagged enum where `channel` has typed direction (inbound = external messages arrive; outbound = the host delivers final replies/notifications, from the adapter section's InboundMessages/ExternalFinalReplyPush flags), the caller's connection state, and the connect affordance. Lifecycle summaries carry channel_directions + channel_connection, produced from the PR-1 manifest projection instead of a section re-parse. Deleted outright (no shims): ConnectableChannelsProductFacade and its DTOs, GET /api/webchat/v2/channels/connectable (route, descriptor, handler, contract rows), slack_connectable_channel.rs, SlackOperatorRouteVisibility, and the never-read channel_connection_facade_slot activation wire. The one-variant LifecycleExtensionSurfaceKind is deleted; every crate imports ironclaw_host_api::CapabilitySurfaceKind from its owner (no facade re-export). ChannelConnectionFacade survives as the caller-scoped binding seam (connection state + disconnect cleanup). External-identity binding is host-owned and product-blind: the new generic ProviderIdentityActorResolver (provider_identity.rs) is parameterized by provider/adapter-id/actor-kind data; slack_actor_identity.rs is deleted and Slack's wiring is a three-line parameterization. A new channel gets actor-to-user resolution by declaring surfaces, not by writing a resolver. Frontend: channels tab renders from installed extensions' channel surfaces; the Slack admin section self-gates on the operator-scoped setup endpoint; the vestigial action-prop chain and the connectable-channels query/invalidation are gone. NEA-25 stack PR 3. Caller-level pins: reborn_services_contract list_extensions_projects_channel_surface_with_directions_and_connection; provider_identity resolver tests; frontend channels-tab/setup-panel suites (602 tests). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * feat(reborn)!: one slack extension - slack_bot and slack_personal retired The Slack channel and the user-scoped Slack tools are one extension. assets/slack/manifest.toml declares both surfaces: the product_adapter.inbound channel section (Events API ingress, request signature verification, host-authored bot egress, inbound+outbound directions) and the capability_provider tools section (search, list, history, user info, send-as-you), under provider `slack`. No per-surface runtime was needed: the retired slack_bot manifest's first_party service declaration was descriptive-only (the host mounts the channel service); the wasm runtime serves the tools. Deleted identities (no aliases): the slack_bot package, assets, digest, catalog-hiding (is_internal_extension_package_ref), onboarding and activation special cases; the slack_personal provider id everywhere including the frontend OAuth-card display map ("personal" survives only in flow-named identifiers for the user-scoped OAuth flow). The slack_bot_token / slack_signing_secret credential HANDLES stay - they are workspace secrets, not identities. Two one-time forward data migrations, both pinned and idempotent: - installation state: loading folds persisted slack_bot manifest records and installation rows into the unified slack extension (enabled-wins merge, credential bindings union, host-bundled manifest record seeded when absent) and persists the migrated snapshot immediately; - credential accounts: a boot sweep in the rooted factory builder rewrites provider slack_personal -> slack via the durable account store (sweep_all_accounts extracted from the refresh-candidate walk). Operator setup-save activation uses the new ChannelSetupActivationCredentialGate: per-caller product-auth accounts never gate operator channel activation - each caller auth-gates at tool-call time (auth_required). With the identities unified, the per-caller channel-connection SetupRequired gate is live for the first time: the connections key and the extension id finally match. NEA-25 stack PR 4. Deployment note: Slack operator env referencing the slack_personal provider id needs a one-word update. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * refactor(reborn)!: extensions wire carries runtime + surfaces, not a conflated kind The extension wire's `kind: String` conflated two axes: product taxonomy ("channel") and runtime implementation ("wasm_tool", "mcp_server"). Both DTOs (RebornExtensionInfo, RebornExtensionRegistryEntry) now carry `runtime: String` - the honest implementation name (wasm / mcp / first_party / system / script; Script no longer masquerades as wasm_tool) - and `surfaces` (registry entries gain them too, via the shared wire_surfaces builder). extension_kind() and wire_kind() are deleted; an axis-separation pin proves a channel-surface extension keeps its runtime label while projecting the channel surface. Frontend follows: extensions-schema exposes RUNTIME_LABELS + extensionSurfaces/hasChannelSurface/hasToolSurface (KIND_LABELS and isChannelExtensionKind deleted); the channels view filters on the channel surface, the tools view on the rest, and the MCP view keys on the honest runtime label as a deliberate operator-facing runtime grouping. Install/configure payloads carry `surfaces` so the modal routes channel-surface extensions to the connect panel without a kind string. i18n extensions.kind.* keys become extensions.runtime.* across all 11 locales (channel/wasm_channel/channel_relay labels deleted). Also folds in the stale-source cleanups the swap surfaced: the webui_v2 CLAUDE.md route table row for the deleted connectable route, assets.rs source pins (setup-panel self-gate, channel-surface pins), test fixture ids still using the retired slack_bot identity, and doc comments naming the deleted parse entry points. NEA-25 stack PR 5. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * test(architecture): zero-legacy gate for the retired NEA-25 taxonomy Pin every identifier the unified extension model retired at zero occurrences across Reborn code (crates/, the WebUI frontend sources, tests/integration/): the connectable-channels rail, the one-variant lifecycle surface kind, the conflated extension `kind` wire string (extension_kind/wire_kind/KIND_LABELS/isChannelExtensionKind), the Slack-specific actor resolver, the contract-free manifest parse paths, and the retired slack_bot / slack_personal identity forms (credential HANDLES like slack_bot_token are matched around, not banned). Sanctioned exceptions are path-scoped: the v1->Reborn migration crate reads v1 vocabulary by design, and the two one-time forward data migrations name the identities they fold forward. v1 (src/, root tests/) is out of scope - it is being strangled wholesale. The gate immediately earned its keep: it flagged dead vm-context stubs for the deleted listConnectableChannels client across the chat-send test harness (33 stubs incl. two feeding nothing but data), a leftover ["connectable-channels"] invalidation in the configure modal, and its two test expectations - all removed here.

Messaging now groups on the declared channel surface (the same hasChannelSurface helper the extensions page uses), and the runtime-keyed MCP rail is deleted outright — runtime is a card badge, never a grouping axis, and tool visibility lives on the Tools views. Regression test: useChannels.test.ts pins surface-derived grouping, rejects a kind-wearing impostor with no channel surface, and pins that no runtime-grouped MCP rail comes back.

The gate now scans .tsx and pins quoted "wasm_channel"/"channel_relay"/"mcp_server" forms; the v1 gateway enclave joins the sanctioned paths (it still serves the v1 kind wire and is strangled wholesale, like src/).

Exactly one of [runtime] or [mcp] declares the implementation; [mcp] is mutually exclusive with [[tools]] and [channel].

Every integration is now an installable extension package driven by a generic runtime that installs, activates, dispatches, and removes using only the manifest plus two adapter seams (ToolAdapter, ChannelAdapter) and one recipe-driven auth engine — no generic crate names or branches on a concrete extension. ~34k lines of per-vendor Slack machinery deleted. Phases (each preserved as a live branch + PR for the review record): P0 (#5993) Architecture gates: specificity scanner + dependency-direction gate + retired-taxonomy gate, allowlist enumerating today's violations; acme-messenger fixture assets.

No production logic changed (only a test-support doc-comment). Checklist (docs/reborn/extension-runtime/checklist.md): - Un-tick the two overstated rows with honest notes: - LIFE-12: shared-vendor grant policy is a P6-deferred no-op stub (FacadeOwnedRemovalHooks::revoke_and_delete_grants); only the empty-case removal context is pinned, so preserve/remove-on-last-consumer is unproven. - DEL-9: the deletion script passes locally (--trees-only green) but no CI workflow invokes it; the dependency-direction half runs via the ironclaw_architecture arch test. The "in CI" clause is unmet (tracked with REL-5). - Tick MAN-8 (reserved trigger/file kinds, wire-pinned, no binding path) and MAN-9 (reborn_code_never_references_retired_taxonomy, green) with named evidence. Annotate MAN-6/MAN-7 as PARTIAL (missing ceiling-rejection / activation-caller tests) rather than tick. - Refresh dead/stale citations: drop nonexistent slack_host_beta.rs and RuntimeHttpEgressUnavailable (OUT-4); correct slack_serve/e2e_tests.rs -> channel_host/e2e_tests.rs and 24 -> 28 count (ING-12, OUT-1); replace two retired OUT-2 test names; correct OUT-9 "both-DB store suite" (libsql-only); narrow AUTH-1's composition sub-note (allowlist-gated, tracked by DEL-8). Tally unchanged at 99 checked / 20 open -- now the correct rows. REL-4 docs: - CHANGELOG [Unreleased]: add entries for the VendorId rename + manifest-v3, the unified delivery coordinator, and the auth-engine/provider-spec deletion. - Correct hard-stale deleted-symbol refs in contracts/{host-api,extensions, communication-delivery-resolution,product-adapters}.md and FEATURE_PARITY.md (RuntimeCredentialAccountProviderId -> VendorId; ProductAdapter -> ChannelAdapter; drop nonexistent ironclaw_channel_adapter crate). - Add RETIRED banners to telegram-v2.md and _contract-freeze-index.md. - Clean a stale HostOAuthProviderSpec doc-comment (test_support).

Greenfield: zero state-migration logic (every deployment wiped). Extension state machine (Option A, owner-decided): - Collapse installation state to ONE honest projection enum: Installed, Configured, Active, Disabled, Failed(terminal), Unsupported (+ Removed signal). - Delete the dormant 7-state in-memory machine, is_transient/resume_target, restore_at_startup, the multi-step host remove()+RemovalPending, and the LifecyclePhase<->InstallationState double-projection mirror (all verified test-only/dead in production). - Add terminal Failed for non-auth activation failure; keep + WIRE the orthogonal auth-account axis (Connected/Expired/RefreshFailed + typed last_error) to the WebUI; drop the never-produced Revoking state. - Wire activation_error + auth-account state to the wire and frontend (honest states rendered; 728/728 frontend tests). Correctness fixes surfaced by the reconciliation: - product_adapter host-API registry: all composition manifest-validation paths use the augmented registry (were failing product_adapter installs). - OAuth continuation: ContinuationDispatchLease single-flight guard (fixes a concurrent-callback deadlock) + fail_completed_continuation compensation so a Failed post-OAuth activation terminalizes instead of falling through. - Strip legacy migration: identity fold, skill backfill, manifest backfill.

A3 (removal cancels pending flows) FLAGGED, not applied: on this branch cleanup_for_lifecycle revokes accounts but never cancels pending flows (a real gap vs main — a late callback could mint a credential post-uninstall).

Auth cluster (owner: use ours; drop main's #5957 dispatch machinery): - Delete the orphaned LifecycleAuthContinuationDispatcher lane (dead at base; extension-card OAuth is SetupOnly + frontend-driven activation, pinned by the restored oauth_callback_with_lifecycle_activation_returns_ok_without_resume) and restore our 2-arg factory dispatcher wiring. - Keep main's canceled-flow-denies-blocked-gate half in product_workflow and add dispatch_canceled_auth_continuation to the dispatcher trait + all impls (production caller lands with the A3 follow-up arm). - Excise main's claim/settle machinery from test fakes (auth_interaction_contract, manual_tokens). Split-artifact repairs (add the missing import/binding, never revert crates): - Dedup both-sides-added tests (extension_search_*, restore_skips_*) and re-express main's LifecyclePhase/LifecycleExtensionSurfaceKind copies onto InstallationState/CapabilitySurfaceKind. - Re-add dropped identifiers: BUDGET_ACCOUNTING_FAILED_CATEGORY import (its absence turned the pinned-summary match into a catch-all), canonicalize_installation_rows, WireState.channel_configs, automation hold-type re-exports (#6066), fs-browse contract-test imports (#5896), VendorId for the retired RuntimeCredentialAccountProviderId name. - Fix duplicate struct-literal fields (requested_model, model_usage) and the frontend importMutation duplicate; teach main's #6088 test our hasChannelSurface taxonomy helper; drop the orphaned mcp-tab.test.ts (component superseded pre-fork by the unified ToolsTab). - Excise all 13 undeclared slack-v2-host-beta cfg sites (main's retired pre-unification test lane; guarded tests drove APIs deleted here). Audit gaps folded (nothing deferred): - #6089: restore resource_governor_libsql_contract.rs + its [[test]] entry. - #6066: restore scenario_triggered_gate_hold_visible.rs. - #6105: re-express the Slack channel lifecycle state-machine scenario onto the generic channel model (generic ChannelConnectionTestBundle over GenericChannelConnectionFacade + identity-binding store, §6.4 removal disconnect slot wired through the group harness). - #6058: strip the deleted ownership-migration crate from Dockerfile.reborn and replace the smoke test with a guard pinning its absence (blank-slate deploy: no state migration ships in this tree). Known-red (inherited from the base, tracked for the follow-up validation phase; #6116 draft CI never ran the test suites, and the identical failure — "timed out waiting for Completed; last status=BlockedAuth" — reproduces at bare 516d6cc65 in a clean worktree): slack activation parks on BlockedAuth under harness credential seeding, failing slack_tools_invoke_through_the_generic_dispatcher_with_recorded_egress and the new #6105 scenario's Phase 1 (the scenario is catching this real pre-existing break); auth_lifecycle's two uninstall-denies-gate tests go green once A3 + the F2 arm land on the PR branch.

Remove the legacy slack events alias smoke test (MIG-5 aliases are deleted; blank-slate deploy mounts no compat routes). - available_extensions: restore main's #5459 InstalledLocal stamp for filesystem-discovered packages (the merge kept the pre-merge HostBundled stamp — a restart could relabel an untrusted upload into first-party trust). The four import/trust pins that caught it pass again unchanged. - extension_lifecycle: fixtures parse v3 through the production version-dispatching entry (ExtensionManifestRecord::from_toml); main-dialect github fixture converted to this branch's capability_provider shape; empty channel_disconnect_slot now FAILS removal loud (typed, retryable, redacted) for channel+auth extensions with an authenticated actor instead of skipping the per-caller disconnect — removal never reports removed:true without cleanup (owner fail-closed ruling). - i18n: all 10 locales reconciled with en — translations added for the 11 Option-A auth-account/state keys; 3 retired state keys (pairing/pairing_required/ready) dropped. extension_host lib: 269 passed / 0 failed. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(reborn): unblock slack extension activation in the integration harness (S3) Two independent defects made slack (and every credentialed extension in a non-user-aligned group) fail activation or the turn after it: 1. Harness credential seeds landed under the wrong user (BlockedAuth). `seed_capability_credential_account` seeded under the capability harness's fixed constructor user, but production capability dispatch (`local_dev_visible_capability_request` / `local_dev_resource_scope_for_run` in `crates/ironclaw_reborn_composition/src/runtime/local_dev.rs`) resolves the execution user per run as thread owner -> run actor -> fixed fallback, and every harness thread run carries an actor, so the fixed fallback never applies. In groups that do not align the harness user to the binding subject (`extension_runtime_acme`, `extension_delivery`), the activation credential gate looked up the run's resolved user, found zero accounts (`accounts_for_owner` -> [] -> `CredentialMissing`), and parked the run BlockedAuth. The seed helper now derives the same owner -> actor resolution production uses, and the now-unused `capability_user_id()` accessor (whose doc claimed the fixed user was the dispatch user) is removed. 2. The bundled slack package omitted three tools' schema/prompt assets (`host_stage_unavailable_capability`). `crates/ironclaw_first_party_extensions/src/packages/slack.rs` shipped schema+prompt assets for only 5 of the manifest's 8 tools — `get_conversation_info`, `get_thread_replies`, and `whoami` were missing. Install materializes only listed assets, so activation succeeded but the NEXT visible-surface refresh failed reading `schemas/slack/get_conversation_info.input.v1.json` (`HostRuntimeError::InvalidRequest` from the hot capability catalog), failing every subsequent turn in the thread — the actual Phase 1 failure in `reborn_group_extensions`. Added the six missing embeds. Regression coverage: extended the existing `bundled_first_party_manifest_asset_refs_are_packaged` test to derive the package set from the catalog itself instead of a hand-maintained id list (slack's absence from that list is exactly how the gap shipped) and to require the WASM runtime module asset as well; it fails naming the exact missing slack schema without fix 2. The activation path itself is pinned by the previously-failing integration tests, now green: `slack_tools_invoke_through_the_generic_dispatcher_with_recorded_egress`, `acme_fixture_lifecycle_dispatches_from_the_active_snapshot` (both storage arms), `reborn_group_extensions` (13/13 incl. the slack channel lifecycle state machine), `reborn_integration_tool_call`, `reborn_integration_extension_ingress`, and `reborn_integration_extension_delivery`. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(e2e): re-express Playwright suite + live canaries onto the unified extension wire; unbreak the Tools tab - extensions-page: the mcp→tools rename was half-finished — the URL guard accepted the dead 'mcp' id (blank page) and bounced the canonical 'tools' id, leaving the Tools view unreachable. Legacy mcp deep-links now redirect to /extensions/tools; sidebar sub-nav uses the tools id + existing key. Regression pins added. - tests/e2e: retired wire fields re-expressed (kind→runtime, activation_status→installation_state, surfaces taxonomy, honest §6.1 states); per-provider OAuth start route dropped from the 401 list (generic /oauth/start); the five native window.confirm remove flows converted to the shared ConfirmDialog (#6084); setup payload mocks use the real lifecycle shape; one pre-existing main e2e bug fixed (banner asserted on the wrong tab; never ran in CI). 43/43 + 7/7 against a real branch binary. - live canaries: provider slack (not slack_personal), generic channel-dm-targets + channel-identities storage layouts, unified registry channel-surface discovery, oauth/slack/callback path. Self-tests 179(+28)+15+60 green; vitest 751/751. Owner follow-ups noted in PR: live Slack OAuth client provisioning path (env wiring removed on this branch) and a stale composition CLAUDE.md routes section. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(auth): audit + review blockers — scope ceiling, Notion refresh, fan-out retryability, removal/callback race (#6128) * fix(auth): clamp exchange scopes to the unified recipe ceiling, not the per-flow request Connecting a second extension of a shared vendor signed the first one out (gmail -> google-docs): each connect requests only its own extension's scopes, a cumulative-grant vendor (recipe data: Google's include_granted_scopes) echoes every previously granted scope, and the A6 clamp stored granted ∩ requested — stripping the first extension's scopes from the single shared vendor account, whose update replaces the scope set (update_account_from_exchange). The account then failed the first extension's scope-aware requirement check. Clamp against the recipe's declared scope ceiling instead — for a shared vendor that ceiling is the cross-manifest union the production resolver already builds (unified_vendor_recipes via bundled_vendor_recipes). The anti-over-claim property holds (scopes no recipe ever declared are still dropped; a narrowed grant is never widened back to the request), while vendor-attested cumulative grants inside the ceiling are preserved. The per-flow request still drives the authorize URL and the downgrade warn. Generic: no vendor branch; Google's cumulative behavior stays declared in its manifest TOML. Regression tests (auth_engine_contract): - exchange_preserves_cumulative_grant_within_unified_ceiling — real gmail + google-docs manifests unioned like production; fails on the old clamp with exactly the reported scope loss (verified red before fix). - exchange_clamps_echoed_scopes_to_recipe_ceiling — reworked A6 pin: an echoed scope outside every declared ceiling is dropped, an omitted requested scope is never widened back in. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(recipes): capture Notion refresh_token + expires_in (A4) The bundled [auth.notion] recipe captured only /access_token, so the pointer-driven engine stored Notion's ~1h access token as non-expiring: nothing ever refreshed and every Notion connection died within the hour. (The parity checklist's green tick rested on main's auto-parsing Standard token shape, which did not survive the unified merge.) TOML-only fix, recipe-only invariant intact: declare /refresh_token and /expires_in captures plus [auth.notion.refresh] rotates_refresh_token = true (OAuth 2.1 DCR public client, single-use rotating refresh tokens). Regression tests (verified red on the old manifest, green after): - auth_engine_contract::notion_recipe_declares_refresh_and_expiry_capture pins the real bundled manifest's capture declarations. - dcr_vendor_registers_once_and_runs_standard_oauth_afterwards extended: the exchange must capture and store the rotating refresh token. Checklist: Notion section re-anchored to this branch's evidence; A16 (DCR client re-register on invalid_client) noted as now non-latent, tracked. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(auth): keep blocked-run fan-out retryable; settle replayed gate continuations idempotently Two related dispatch-semantics fixes (audit blocker #2; independently reported by the mega-PR review as 'BlockedAuth fanout failures become permanently non-retryable'): 1. An incomplete fan-out sweep (unreadable turn snapshot, or any resume failure) now returns an error so the completed flow's continuation is NEVER marked dispatched — the re-drive paths (browser flow reconcile, lifecycle cleanup re-enumeration) retry the whole dispatch. Previously the sweep was best-effort: one transient coordinator error permanently stranded every other parked run of the provider. The sweep still continues past a failing run so one wedged run cannot starve the rest. 2. Replays are made safe end-to-end by settling the primary resume idempotently, the same way the deny path already does: a continuation whose gate is no longer the run's blocked gate (the run resumed, or re-blocked on a NEW gate) converges as a side-effect-free Ok instead of erroring forever. The safety property — a stale reference never resumes a different gate, an auth continuation never resolves a non-auth gate — is unchanged and still pinned (side-effect-freedom asserts kept); what changes is convergence instead of a permanently unacknowledged flow and a reconcile loop hammering a non-retryable error. Tests: - blocked_auth_resume: incomplete_fan_out_keeps_the_continuation_retryable (first dispatch fails with a transient resume error and surfaces it; the re-driven dispatch completes the sweep; run resumed exactly once) — replaces the best-effort pin, which failed against the new semantics. - product_workflow: resume_continuation_leaves_settled_gate_untouched (superseded gate + already-resumed run both converge with zero coordinator calls); the two old rejects-stale pins reworked to assert side-effect-free convergence (they failed red against the new code for the old semantics, as expected). - factory/auth_tests: oauth_callback_with_stale_gate_converges_without_ resuming — the callback now succeeds, the credential is minted, and the run stays parked on its CURRENT gate untouched. Suite status: product_workflow lib 93/93; composition lib 1199 passing; the 2 remaining composition failures are not from this change: production_libsql_oauth_callback_fans_out_* is red on the unmodified base (verified by stash-and-run), and gate_prompt_is_posted_exactly_once_* is a parallelism flake (green 3/3 standalone). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(auth): close the removal/callback credential-resurrection race Mega-PR review finding ('OAuth callback can recreate credentials during removal', verified): lifecycle cleanup enumerated accounts FIRST and canceled flows second, so a callback completing between the two minted a credential the scan had already missed; the flow loop then saw the terminal flow as a desired end state and removal returned success with a live credential for the removed extension. Fix, two layers: 1. Reorder cleanup_for_lifecycle (durable + fake): cancel the provider's pending flows FIRST, then enumerate accounts. A racing callback either loses — its flow is canceled before complete_oauth_callback can write an account — or wins and completes first, in which case its mint already exists when the (now-later) scan runs and is revoked like any other. F2 continuation reporting rides the flow pass unchanged. 2. Callback-side compensation (cross-replica defense): if the flow's completion write loses its CAS race after the account write (a concurrent lifecycle cancel on another replica — no shared in-process lock), revoke the just-minted account and purge its secret handles best-effort before surfacing the original conflict (compensate_unanchored_callback_account). Test: extended completed_unacknowledged_turn_gate_cleanup_emits_once_ then_converges with the callback-wins invariant — the completed flow's credential is revoked by the same cleanup pass. The exact mid-cleanup interleave is not deterministically reachable at the contract tier (the durable store's per-flow lock serializes it in-process; the reorder closes the cross-phase window by construction) — per testing.md this limitation is documented here and in the PR rather than faked with a timing test. Suites: ironclaw_auth 30+27+70 green; composition product_auth 139 green. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * docs(extensions): correct the resolved-manifest contract to blank-slate fail-loud The `WireManifestRecord.resolved` doc comment still described a legacy backfill ("absent only on legacy records, which backfill by compiling once at load") that the code below it does NOT do — `into_manifest_record` fails loud on an absent resolved contract. Per the owner directive (no state-migration logic anywhere for the new extension state; blank-slate deploy), the fail-loud behavior is correct and Henry's "backfill from old raw_toml" required-fix is rejected. Comment-only; behavior unchanged.

Single-mutex DeliveryRunLedger: active single-flight set + bounded delivered-run memory, one atomic claim decision (two locks would reintroduce the TOCTOU); delivered recorded at the terminal-notification point, so a failed/timed-out loop stays retryable by a later ack.

[skip-regression-check] Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(reborn): restore the installed-inventory guard on extension OAuth start; 409 replayed callbacks on settled flows Two dropped production halves of main-pinned behavior (both from the #5957 fold), found while fixing the red composition-core bucket: - The extension OAuth start route now requires the requester extension to be in the caller's installed inventory (fail-closed: unwired lookup rejects 503, absent extension rejects 409 invalid_request before any flow work), re-checks after flow creation, and aborts the just-started flow (cancel + PKCE-verifier drop) when an uninstall races the start. The merge had fused main's two tests into one (main's reject-test name over the binding-test body) and dropped the guard entirely — a start for a non-installed package returned 200. De-fused: `extension_oauth_start_rejects_package_missing_ from_installed_inventory` (guard fires before the engine is resolved) + `extension_oauth_start_for_installed_package_attaches_update_binding`, plus the race pin (`..._aborts_the_started_flow_when_uninstall_races`) and the fail-closed pin (`installed_extension_lookup_is_required_even_in_ test_builds`). Production wiring: `webui_serve` hands the bundle's `RebornServicesApi` to the route state (`with_webui_api`). - `ensure_oauth_callback_flow_known` now rejects a settled flow with `FlowAlreadyTerminal` (409 flow_already_terminal) before the expiry check and the PKCE-verifier lookup, so a replayed callback can't surface the process-local verifier purge as an incidental 404. Pins the already- committed replay legs in `product_auth_google_oauth_callback_rejects_ disallowed_scopes` / `..._rejects_empty_parsed_scopes`. Note (Auth=ours): the route rejects replays for EVERY terminal state including Completed — manager-level claim idempotency on completed flows is unchanged; main's completed-replay success re-render rides its continuation-redispatch machinery, which stays out by owner decision. - The binding test's continuation assertion is re-expressed onto SetupOnly: extension-card OAuth starts create SetupOnly flows (frontend-driven activation), the LifecycleActivation continuation lane is retired. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * refactor(dispatcher): delete BoundCapabilityRequest, adapters take CapabilityDispatchRequest The struct was field-for-field identical to host_api::CapabilityDispatchRequest (which this crate already re-exports) and its sole construction was an identity copy at dispatch time — the §1.1 mechanism-1 re-wrap the architecture- simplification doc targets. BoundCapabilityAdapter now receives the authorized request unchanged; the reservation-ownership contract moved onto the trait doc. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(extension-host): durable reply-context store over ScopedFilesystem The ingress reply-context store (ING-11) was a hand-written process-local InMemoryReplyContextStore wired into production — every pre-admission reply context was lost on restart, so a source-route reply after a restart had no context to bind to. Replace it with a CAS-updated snapshot per (extension, installation) on the tenant-shared filesystem (latest context per conversation, same bounded FIFO eviction), following the FilesystemChannelDmTargetStore pattern and arch-simplification §4.3 (in-memory is a backend, not a store — tests ride InMemoryBackend). Regression test: contexts_survive_store_recreation_over_the_same_filesystem (red by construction against the deleted process-local store, whose state died with the instance). Router contract tests keep a file-local fake. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * refactor(host-api,extensions): sweep dead capability-ABI surface, collapse normalized-message twins - Delete ScopedToolState (+error) and the always-None ToolPorts.state slot: zero implementors, zero references outside host_api. Re-add with the first real consumer. - Delete ResolvedExtensionManifestExt: empty blanket-impl extension trait with zero callers (generic_host computes the predicates inline). - Drop ToolCall.invocation_id: the invocation identity already rides ToolCall.scope (ResourceScope.invocation_id); the field was a §1.1 dead-accretion duplicate. - Slack/Telegram: delete the byte-identical {Slack,Telegram}NormalizedMessage intermediates; normalize_* now constructs the ChannelAdapter contract's NormalizedInboundMessage directly (AttachmentRef mapping moved into the normalizers, channel inbound() is a pass-through). NormalizedInboundMessage gains derive(Debug), matching what the twins already exposed. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * refactor(extension-host): rename InMemoryInstallationRecordStore to RehydratedInstallationRecordStore It is not a §4.3-class parallel store: it is the boot-rehydrated derived execution view of the durable ExtensionInstallationStore (lifecycle.md), with no durable twin of its port to maintain in lock-step. The old name put it in the banned InMemory*Store class and its doc claimed 'for contract tests' while production wires it at generic_host — name and doc now say what it is.

Conformance imports GroupTriggerPolicy from its owner. Protocol tests ride the engine crate (identical 36-test twin); adapter/conformance suites stay. Verified: both crate suites, reborn_integration_extension_delivery 16/16 (telegram update -> turn -> coordinated reply on libsql + Postgres), architecture suite 63/0, clippy -D warnings on both crates. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * feat(reborn): generic WebGeneratedCode channel pairing seam (P2) The second connect strategy goes generic: composition builds a vendor-blind pairing service per binary-assembled account-setup descriptor declaring WebGeneratedCode. Codes mint web-side (rotating, 15-min TTL, CAS-claimed single winner) and are consumed by the channel's verified webhook through a new pre-admission gate on the generic inbound sink; consumption binds the external actor through the installation-scoped identity bindings under the extension-id provider, records the DM target in the canonical store, and resumes parked runs via the standard SetupOnly auth-continuation fan-out (idempotent completion outbox retried from status polling). Unpair drops codes, bindings, the DM target, and conversation-actor pairings together, and extension removal + channel disconnect route through the same service. Wiring: descriptors ride RebornBuildInput (the CLI declares telegram's, including the t.me deep-link template resolved from non-secret channel config), the lifecycle consults descriptors for connect strategy/copy, the channel host resolves inbound actors for pairing extensions through the identity lookup (unbound actors fail closed instead of inheriting the operator), and bearer-authed mint/status/unpair routes mount per extension through the protected-route seam. Frontend: the pairing panel and its API client generalize (code + optional deep link/QR + countdown + poll + disconnect, vendor copy via i18n {name}-interpolated keys and the wire requirement); the Configure modal probes the generic status route to pick the minted-code panel over the proof-code paste box, and the chat onboarding card routes purely on the declared strategy. Fold repairs folded in: main's #6203 fail-closed approval-lookup projection (store outage renders a transient stream failure, not a contextless prompt), the get_job_logs v2 parity baseline + output_schema_ref dialect rule, and the external-channel activation-copy pin. Verified: composition 1528/0 (incl. 9 new pairing unit tests + interceptor), integration extension delivery+ingress 31/0, architecture 63/0, frontend tsc + vitest 803/803, clippy three-lane matrix -D warnings clean.

P2 — adapters,
ExtensionHost, and the tool-dispatch cutoverThird PR of the extension-runtime train (design:
docs/reborn/extension-runtime/). P2a landed the generic contracts; this completes the phase with Workstream C and the production composition.The dispatch cutover (TOOL-1/2/3)
RuntimeDispatchernow resolves a prebound adapter by capability id through the injectedToolResolverport — the per-invocation registry/package/runtime-kind selection is deleted, andironclaw_dispatcherno longer depends onironclaw_extensions/ironclaw_filesystemat all (retiring a scheduled layer-matrix exception). The production chain is[active-snapshot resolver → registry lane], with the registry lane restricted to the syntheticbuiltinprovider once the snapshot resolver is installed: activated-extension dispatch has exactly one path, no fallback.TOOL-3 is pinned at the callers: capability-host × dispatcher integration (approval block/resume, wrong-user/expired-lease rejections), the host-runtime vertical slice (obligations fail before dispatch), the rewritten dispatcher event contracts, 9 real-wasmtime lane tests, and the full composition suite. One documented event delta: a missing-backend failure now emits
runtime_selectedbeforedispatch_failed(selection succeeded at bind time; the backend is what's missing).ExtensionHostcomposed (first production impls of the P2a traits)CompositionExtensionLoaderdispatches by resolved runtime kind: binary-assembled native factories (RebornBuildInput::with_native_extension_factories— empty in production until P6), the first-party registry bridge (gmail/gsuite/web-access until their crates extract), and the wasm/mcp/script lane binder (ExtensionLaneToolBinder, the narrow host-runtime factory that keeps the lanes sealed). A channel-declaring extension whose serve graph is still host-owned (Slack) binds a transitional no-route bridge so the binding rule holds until P4/P5. The lifecycle facade remains the durable-lifecycle owner and drives the host at its choke points (activation commit with unwind compensation, removal unpublish, boot hydration); durable seven-state ownership and the host-owned removal order migrate in P6.The hosted-MCP discovery bug is fixed (pre-existing)
Discovery runs at activation, outside the dispatch obligation pipeline, so nothing staged the connection credential/network policy —
tools/listalways failed transient and silently fell back. Activation now stages both under the discovery scope; the P1 truth-pin flipped:local_dev_extension_activate_hosted_mcp_stages_discovery_and_publishes_toolsproves live discovery through the REAL egress pipeline with the staged credential observed on the vendor wire, and the discovered tool published model-visible.Integration proof +
