From cdf173d1740e540becc2ecb340999d010a6f33e6 Mon Sep 17 00:00:00 2001 From: Zaki Date: Wed, 13 May 2026 05:39:39 -0700 Subject: [PATCH 01/46] feat(reborn): add ironclaw_hooks framework foundation (#3524) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Foundation slice of the Reborn loop hooks framework per nearai/ironclaw#3524. Lands the trust primitives, sealed decision types, dispatcher contract, and extension manifest schema; no Reborn middleware composition yet (next slice wires HookDispatcher into LoopCapabilityPort / LoopPromptPort). Design comment on #3524: https://github.com/nearai/ironclaw/issues/3524#issuecomment-4439890144 What this PR ships ================== * `crates/ironclaw_hooks/` — new crate * `identity` — content-addressed `HookId` (blake3 of length-prefixed extension + local + version fields). Same versioning primitive the rest of Reborn should converge on for replay safety. * `trust` — `HookTrustClass` enum (Builtin / Trusted / Installed) with per-kind default attenuation. Trust class is fixed by source, never declarable. * `kinds/` — sealed decision DTOs. `BeforeCapabilityHookDecision`, `HookPatch`, `ObserverFact` all have `pub` outer struct + `pub(crate)` inner enum + `pub(crate)` constructors. Same #3460 witness pattern. * `points/` — typed read-only contexts for each hook point. * `sink` — split sink traits per trust tier. `PrivilegedGateSink` exposes `allow()`; `RestrictedGateSink` does not. An Installed-tier hook literally cannot mint Allow at the type level. * `ordering` — phase → priority → hook id, stable. Phases gated by trust (Validation/Authorization Builtin-only). * `failure_policy` — Timeout/Panic/Malformed/AttenuationViolation categories. Gate/Mutator fail closed, Observer/Effect fail isolated. Slot poisoning persisted for the rest of the run on any category. * `registry` — run-profile-sourced bindings; phase-vs-trust gate enforced at insert; poisoning surface for the dispatcher. * `dispatch` — HookDispatcher with deterministic ordering, panic catch-unwind via futures::FutureExt, per-hook tokio::time::timeout, short-circuit gate composition (Deny > PauseAuth > PauseApproval > Allow), Telemetry-phase observers always run. * `manifest` — serde types for the `[[hooks]]` section of extension manifests. Predicate vs WASM body; same_tenant scope requires explicit grant; Validation/Authorization phases rejected at parse time because manifest hooks are always Installed. * `predicate` — typed predicate language for declarative Installed hooks (DenyCapability, PauseApproval, RateOrValueCap). Evaluator lives in the dispatcher follow-up, not here. * `crates/ironclaw_architecture/tests/reborn_dependency_boundaries.rs` * Added `ironclaw_turns` -> `ironclaw_hooks` to the forbidden list. * New BoundaryRule for `ironclaw_hooks` itself (cannot pull host_runtime, dispatcher, secrets, network, wasm, etc.). * `Cargo.toml` workspace member registration. What this PR deliberately does NOT ship ======================================== * Reborn middleware composition wrapping LoopCapabilityPort / LoopPromptPort with HookDispatcher. Next slice; ironclaw_reborn changes only. * WASM hook execution path. Programmatic hooks parse and validate from manifest; the wasmtime integration lands when the WASM dispatcher seam is built. * Predicate evaluation. Predicate types serialize and validate; the evaluator that turns a `RateOrValueCap` spec into a `Deny` decision is in the next slice alongside Reborn wiring. * Event-triggered hooks (Phase 5 of the original roadmap). * Self-authored hooks. Tracked separately at #3567 with monotonic-restriction + unforgeable-channel ratification. Test plan ========= * `cargo test -p ironclaw_hooks` — 47 tests (46 unit + 1 integration smoke for the manifest -> binding -> dispatch pipeline). * `cargo test -p ironclaw_architecture` — 13 tests; new boundary rule passes, existing rules unaffected. * `cargo clippy -p ironclaw_hooks --all-targets -- -D warnings` — clean. * `cargo fmt -p ironclaw_hooks -- --check` — clean. * `cargo check --workspace` — clean, no regressions in other crates.

Adds the next layer: 1. Capability- and prompt-port middleware (`ironclaw_hooks::middleware`) * `HookedLoopCapabilityPort` runs `dispatch_before_capability` before every invocation, translates the composed decision into the existing `CapabilityOutcome` vocabulary (Deny / PauseApproval / PauseAuth all map to `Denied` for now; gate-ref plumbing for real pause semantics lands in the next slice). * `HookedLoopPromptPort` runs `dispatch_before_prompt` before bundle construction. Observe-only for snippets in this slice; actual snippet injection waits for the shared `prompt_envelope::wrap_untrusted` helper (#3540 / #3471). 2. Declarative predicate evaluator (`ironclaw_hooks::evaluator`) * `DenyCapability` and `PauseApproval` predicates: stateless, evaluated directly against `BeforeCapabilityHookContext`. * `RateOrValueCap` with `InvocationCount` bound: sliding-window counter keyed by `(hook_id, capability_name)`, in-memory only. Window parsing supports `s`/`m`/`h`/`d` units; unparseable windows fail closed. * `NumericSum` bound: types implemented but evaluation returns Allow and emits a warn-level audit. Full argument-extraction story is a follow-up slice once capability arguments become hook-visible. * `PredicateEvaluator::evaluate_at(...)` test variant accepts an explicit `Instant` so sliding-window tests don't depend on real-clock progress. 3. Manifest -> dispatcher glue (`ironclaw_hooks::installed_hook`) * `PredicateBackedBeforeCapabilityHook` wraps a `HookPredicateSpec` plus an `Arc` and implements `RestrictedBeforeCapabilityHook`. The registry installer would construct one of these per `[[hooks]]` entry whose body is `HookManifestBody::Predicate`. * Sink reasons are `&'static str`, so the dynamic predicate `reason` surfaces in audit (via the evaluator's `EvaluatorDecision`) rather than the model-visible decision. Closed-vocabulary labels carry through to the sink. 4. Reborn composition seam (`ironclaw_reborn::loop_driver_host`) * `RebornLoopDriverHostFactory::with_hook_dispatcher(Arc)` opt-in builder method. When set, the factory wraps the capability and prompt ports with the hooked middleware. Default behavior (no dispatcher) is unchanged from the pre-hooks shape, so existing callers continue to work. * Added `ironclaw_hooks` as a dep in `ironclaw_reborn`. Test plan ========= * `cargo test -p ironclaw_hooks` — 60 tests pass (59 unit + 1 integration smoke; +13 vs the foundation commit covering middleware, evaluator, installed_hook). * `cargo test -p ironclaw_reborn` — 118 tests pass; no regressions from adding the dep. * `cargo test -p ironclaw_architecture` — 13 tests pass; the `ironclaw_turns -> ironclaw_hooks` boundary still holds and the new `ironclaw_hooks` rule (no host_runtime / dispatcher / secrets / network / wasm / reborn) is unaffected. * `cargo clippy -p ironclaw_hooks --all-targets --all-features -- -D warnings` — clean. * `cargo clippy -p ironclaw_reborn --all-targets -- -D warnings` — clean. * `cargo fmt --all -- --check` — clean. What still defers ================== * WASM hook execution path. * Persistent predicate counter (in-memory only for now). * Argument-extraction so `NumericSum` predicates evaluate against capability arguments. * Gate-ref plumbing so PauseApproval / PauseAuth surface real `CapabilityOutcome::ApprovalRequired` instead of `Denied`. * Prompt-snippet injection (waits for shared envelope helper). * Event-triggered hooks. * Self-authored hooks (#3567).

Tests drive host.invoke_capability(...) (not dispatcher.dispatch_before_capability(...) directly) so a regression in RebornLoopDriverHostFactory's wrapping composition surfaces here. Scenarios: - PredicateBackedBeforeCapabilityHook (DenyCapability NameEquals "cap.blocked") short-circuits invocation; inner port never called; outcome is Denied(unknown("hook_denied")). - A privileged selective hook that allows non-matching capabilities proves the wrapper does not blanket-deny: cap.allowed reaches the inner port and completes once. - Factory built without with_hook_dispatcher() lets cap.blocked through to the inner port, proving the hook plumbing is genuinely opt-in.

charset=UTF-8 Content-Transfer-Encoding: 8bit Three additions to ironclaw_hooks: B. `pass()` on gate sinks — distinguishes "evaluated, no opinion" from "returned without minting a decision." A passing hook contributes nothing to the composed decision; a silent hook is still Malformed and fails closed. `PredicateBackedBeforeCapabilityHook` now routes the evaluator's `Allow` decision through `sink.pass()` instead of the previous `deny("hook_predicate_pass")` workaround. A. `HookRegistrar` bridge — converts a `Vec` into `HookBinding`s + dispatcher impls in one call. Predicate bodies are wired through `PredicateBackedBeforeCapabilityHook`; WASM bodies return `HookError::RegistryConstruction` for now. Adds `HookDispatcher::insert_binding` so the registrar can mutate the registry through the dispatcher rather than reach inside. I. Self-authored hooks scaffolding — fourth `HookTrustClass` variant for hooks the agent authors at runtime. Run-scoped only; monotonic-restriction sink with no `allow`, no trusted-snippet path, no effect-class constructor. Closed-vocabulary `SelfAuthoredReason` enum keeps free-text reasons off the audit seam. `SelfAuthorshipProvenance` captures authoring run/turn, timestamp, spec digest, optional user ratification, and a generation-trace pointer. Durable persistence depends on the unforgeable channel from #3564 and lands separately.

Hooks that wanted to pause the loop for approval or auth instead failed the call closed, leaving the host's approval-router machinery unreachable from hook code. This change introduces a `HookGateRefFactory` trait in `ironclaw_hooks::middleware::gate_ref` that mints `LoopGateRef`s for pause-class decisions. `HookedLoopCapabilityPort` now takes an `Arc`, defaulting to `UuidHookGateRefFactory` (a locally-unique opaque-id factory suitable for tests and the foundation slice). Production deployments override via `.with_gate_ref_factory(...)` with a factory bound to the current `LoopRunContext` and the host's gate-router. The translation in `decision_to_outcome` is now async so it can await the factory. `PauseApproval` maps to `CapabilityOutcome::ApprovalRequired { gate_ref, safe_summary }` and `PauseAuth` to `AuthRequired`. If the factory itself errors, the middleware falls back to `Denied` with a sanitized `hook_gate_ref_unavailable` reason kind so the loop fails closed rather than routing through an unresolvable suspension. The underlying error text is dropped to avoid leaking gate-router state into model-visible output. Tests: - `pause_approval_decision_surfaces_as_approval_required`, `pause_auth_decision_surfaces_as_auth_required`, `gate_ref_factory_failure_falls_back_to_denied` in `middleware::capability_port::tests`. - `pause_approval_hook_surfaces_as_approval_required_with_real_gate_ref` in `crates/ironclaw_reborn/tests/hooks_integration.rs`, exercising the full `RebornLoopDriverHostFactory` composition with the default `UuidHookGateRefFactory`. - Gate-ref factory unit tests in `gate_ref::tests`.

Strings truncate to 256 bytes; objects/arrays cap at 8-deep. `extract_numeric` supports dotted + bracketed paths (`order.amount`, `items[0].price`) and returns `Option`. The inner representation is sealed so external callers can't bypass bounds. - Introduce `CapabilityInputResolver` + bundled `NullCapabilityInputResolver` in `middleware/resolver.rs`. The hooks crate intentionally doesn't know how to dereference a `CapabilityInputRef` — that knowledge belongs to the production host. Until a real resolver is wired in (follow-up), arguments are `Unresolved` and `NumericSum` fails closed. - `HookedLoopCapabilityPort::new` defaults to the null resolver; new builder `.with_resolver(Arc)` overrides. - `PredicateEvaluator` gains a tenant-keyed `value_history` map. The `NumericSum` arm parses `max` + `window`, extracts the numeric value from sanitized args, accumulates within the rolling window, and applies `on_exceeded` when the sum exceeds the cap. Unresolved args, missing field, non-numeric field, unparseable max, and unparseable window all fail closed via the configured `OnExceededAction`. - Add `BeforeCapabilityHookContext::new_unresolved(...)` convenience ctor; existing test sites switch to it instead of churning every call site through the 4-arg ctor. Test count: +14 (8 new SanitizedArguments tests, 6 new NumericSum evaluator tests, 1 null-resolver test; one old NumericSum-stub-related gap closed).

Sealed `BeforeCapabilityHookImpl`, `BeforePromptHookImpl`, and `ObserverHookImpl` to `pub(crate)` and replaced the single generic `install_before_capability` / `install_before_prompt` / `install_observer` surface with tier-specific public installers (`install_builtin_*`, `install_trusted_*`, `install_installed_*`) that build the binding with the matching trust class internally. Updated registrar, internal middleware tests, the hooks foundation pipeline test, and the reborn `hooks_integration` test to drive the new surface. Added regression tests proving the trust class is set by the installer and that the seal is type-level. - C5 (Medium, Slot Poisoning): same-dispatch poisoning was incomplete because `ordered_bindings` snapshots once at the top of the loop, and `HookRegistry::insert` accepted duplicate hook IDs. Rejected duplicate hook IDs (any point) in `HookRegistry::insert` and added a poison re-check before invoking each hook impl in `dispatch_before_capability`, `dispatch_before_prompt`, and `dispatch_observer_at`. Added regression tests for both behaviors. - C6 (Medium, Manifest / Predicate Validation): `parse_window` could panic on non-ASCII input because `split_at(len - 1)` requires a char boundary. Rewrote to compute the unit char's UTF-8 byte length and slice safely, added a public `validate_window` helper, and wired it into `HookManifestEntry::validate` for both `InvocationCount` and `NumericSum` bounds. Added tests for non-ASCII, empty, single-char, and zero-duration windows. - C2 (High, Tenant Isolation): partial fix only. The `PredicateEvaluator`'s sliding-window counter was keyed by `(hook_id, capability)`, so cross-tenant state could leak. Extended `HistoryKey` to include `tenant_id` and added a regression test proving counters partition by tenant. Documented the broader dispatcher-per-build / per-run-fresh-dispatcher pattern as deferred follow-up in `crates/ironclaw_hooks/CLAUDE.md`.

Previously, hook dispatch was invisible — denies, pauses, failures, and observer fires left no trace in the host's observability backend. Changes: - `ironclaw_turns`: add `HookDispatched`, `HookDecisionEmitted`, and `HookFailed` variants to `LoopHostMilestoneKind`, with a closed- vocabulary `HookDecisionSummary` enum (Allow/Deny/PauseApproval/ PauseAuth/Pass/Patch). Introduce a lightweight `HookMilestoneSink` trait that emits hook-specific *kinds* without requiring a `LoopRunContext` (the dispatcher is a process-wide singleton that cannot own a per-run context), plus a `RunScopedHookMilestoneSink` adapter that injects run context and forwards to the existing `LoopHostMilestoneSink`. Also add `InMemoryHookMilestoneSink` for tests. - `ironclaw_hooks`: add a `telemetry` module that converts hook-crate types (`HookId`, `HookTrustClass`, `HookPointSpec`, `FailureCategory`, `FailureDisposition`, `BeforeCapabilityHookDecision`) into the wire- shape labels and summaries the milestone sink expects. Hook ids cross the seam as hex strings because the strongly-typed `HookId` cannot be imported from `ironclaw_turns` (the architecture test enforces `ironclaw_turns -> ironclaw_hooks` stays absent). - `ironclaw_hooks::dispatch`: add an optional `Arc` to `HookDispatcher`, set via `with_milestone_sink`. Emit `HookDispatched` before each hook runs, `HookDecisionEmitted` after a decision/pass/patch, and `HookFailed` on timeout/panic/malformed/missing-impl across all three dispatch paths (before_capability, before_prompt, observer). Default behavior (no sink attached) emits nothing — preserves the pre-telemetry observable surface. - `ironclaw_reborn`: document on `with_hook_dispatcher` that callers attach the milestone sink to the dispatcher *before* wrapping it in `Arc` and installing it into the factory, using a `RunScopedHookMilestoneSink` to inject run-context. The dispatcher itself is shared across runs, so attaching a fixed run-context inside it would be wrong. Update `RuntimeEvent` projection in `milestone_events.rs` to ignore the new hook kinds (no projection pathway yet; emitted milestones are consumed by SSE observers directly). Tests: - `ironclaw_hooks::dispatch`: 5 new tests covering milestone emission for deny decisions, panic failures, prompt-mutator patches, observer pass-throughs, and the no-sink default. - `ironclaw_reborn` hooks_integration: end-to-end test wiring a `RunScopedHookMilestoneSink` onto the dispatcher and asserting hook activity surfaces in the host's `LoopHostMilestoneSink`. Total: +6 hook telemetry tests; no existing tests modified.

Migrates `ironclaw_host_runtime::memory_context` to delegate envelope wrapping, marker rejection, and control-character stripping to the new crate while keeping the `LoopSafeSummary`-specific 512-byte cap and byte truncation local. Existing memory_context behavior and tests are preserved. Wires the same envelope into `ironclaw_hooks`: * `HookPatch::add_enveloped_snippet` now takes a raw body and wraps it via `wrap_untrusted(EnvelopeSource::Hook, …)`. `Installed` hooks produce `Untrusted` envelopes; `Builtin`/`Trusted`/`SelfAuthored` produce `Trusted` envelopes so downstream readers can distinguish the two paths through a uniform marker. * `HookedLoopPromptPort::build_prompt_bundle` is no longer observe-only. After dispatching `before_prompt`, it envelope-wraps every snippet patch (passing `Enveloped` through, wrapping `Trusted` with the envelope helper), enforces the 4 KiB aggregate snippet byte budget across patches, and appends the wrapped snippets to the prompt bundle's `messages` as `system`-role `LoopModelMessage` entries carrying deterministic `msg:hook..` content refs (mirroring the skill-snippet ref convention). The envelope crate is a leaf with no ironclaw dependencies, satisfying the boundary contract; the existing `ironclaw_hooks` boundary rule in `reborn_dependency_boundaries` continues to hold because `ironclaw_prompt_envelope` is not on its forbidden list. Test count delta: * `ironclaw_prompt_envelope`: +13 new tests (crate did not exist). * `ironclaw_hooks`: 84 → 88 tests (+4 prompt-port behavior tests: `hook_patch_appended_as_envelope_wrapped_message`, `total_byte_budget_enforced_across_patches`, `instruction_hijack_in_patch_rejected`, `trusted_hook_patch_wrapped_with_trust_marker`). * `ironclaw_host_runtime` memory_context: unchanged (8 tests still pass).

Document the MissingImpl path as the one case that emits a sole HookFailed with no preceding HookDispatched (the dispatcher discovers the protocol violation before the hook is actually dispatched). Add a multi-hook dispatch test that installs three hooks with mixed outcomes (allow/deny/panic) at the same point and asserts each hook produces its own paired sequence in the deterministic (phase, priority, hook_id) order taken from the dispatcher's registry.

The wrappers are applied only when a HookDispatcher is set on the factory, so the default factory shape is unchanged. Add four integration scenarios in crates/ironclaw_reborn/tests/hooks_integration.rs: - observer_hook_fires_after_model_through_factory - observer_hook_fires_after_capability_through_factory - observer_hook_fires_after_checkpoint_through_factory - observer_panic_does_not_fail_model_call (panic-isolation regression) Relax the test-fixture model gateway from "panic if invoked" to returning a stub assistant reply so the AfterModel / panic-isolation tests can drive stream_model through the wrapped port. The existing capability-port tests never touch the gateway, so their behavior is unchanged.

The terminal `.build_arc()` wraps in `Arc` and yields an immutable handle. Tightens the public surface on `HookDispatcher`: `new`, `with_timeout`, `with_milestone_sink`, and every `install_*_*` method are now `pub(crate)`. Outside callers route exclusively through the builder, so "wire the milestone sink before Arc-wrapping" is a compile-time fact rather than a documentation convention. `HookRegistrar::install` now takes a `HookDispatcherBuilder` by value and returns `(HookDispatcherBuilder, Vec)`, keeping the builder chainable through manifest installation. `RebornLoopDriverHostFactory` gains `with_hook_dispatcher_builder` to let callers defer `.build_arc()` to the factory — a step toward the FU8 per-build dispatcher pattern. Migrates `foundation_pipeline.rs` and `hooks_integration.rs` to the builder. Internal middleware and dispatch tests continue to use the crate-private `HookDispatcher::new` directly.

RebornLoopDriverHostFactory gains with_capability_input_resolver(...), and when both a hook dispatcher and resolver are configured the factory threads the adapter into HookedLoopCapabilityPort::with_resolver — so NumericSum and other argument-dependent predicates evaluate against real, sanitized inputs instead of failing closed against the framework's null default. The adapter also enforces a configurable serialized-byte budget (default 64 KiB) as defense in depth ahead of the hooks crate's per-string and depth caps in SanitizedArguments. Unit tests cover the four adapter branches (resolved JSON, inner-error → None, non-object pass-through, oversized → None) and a new end-to-end integration test (numeric_sum_predicate_caps_total_value_against_real_inputs) drives the full factory wiring: with a NumericSum cap of 99 over an "amount" field, two invocations carrying {"amount":"50"} let the first pass through and deny the second at the hook seam, with the inner port reached exactly once.

The closure is invoked once per `build_text_only_host*` call, so dispatcher-owned mutable state — slot poisoning, registry mutations, predicate-counter siblings — is scoped to a single host build instead of shared across every host the factory produces. The legacy `with_hook_dispatcher(Arc)` adapter is kept as a thin wrapper that returns clones of the same `Arc` on every build. Its shared-state behavior is now documented as an explicit opt-in for backward compat; new wiring should prefer the factory closure. Adds two regression tests: - `per_build_dispatcher_state_does_not_leak_across_runs` — installs a panicking hook, builds two hosts back-to-back, and proves the inner port is never reached on build 2 (fresh slot still applies the fail-closed deny). Pins per-run isolation. - `legacy_with_hook_dispatcher_shares_state_across_builds` — pins the shared-state semantic of the legacy adapter as the explicit baseline. Migrates `predicate_deny_hook_short_circuits_inner_port` to the new factory-closure path so the new wiring is exercised by the existing suite.

Earlier +slices held one `Arc` on the Reborn factory and reused it +for every `build_text_only_host*` call, which meant a hook poisoned during +run N stayed disabled for runs N+1, N+2, … The +`PredicateEvaluator`'s sliding-window counter is keyed by +`(hook_id, tenant_id, capability)` so rate-cap state was already correctly +partitioned across tenants, but the dispatcher itself was not. + +The Reborn factory now accepts a **closure** that mints a fresh dispatcher +per host build: + +```rust +RebornLoopDriverHostFactory::new(/* … */) + .with_hook_dispatcher_factory(move || { + let mut dispatcher = HookDispatcher::new(HookRegistry::new()); + dispatcher + .install_builtin_before_capability( + hook_id, + HookPhase::Policy, + Box::new(my_hook), + ) + .expect("install hook"); + // Optional: per-build telemetry wiring. + let sink = Arc::new(RunScopedHookMilestoneSink::new( + run_context.clone(), + Arc::clone(&host_milestone_sink) as _, + )); + Arc::new(dispatcher.with_milestone_sink(sink)) + }); +``` + +The closure must be `Fn + Send + Sync + 'static` and return +`Arc`. It is invoked exactly once per +`build_text_only_host*` call, so any state captured inside (e.g. the +template registry, the milestone-sink template, or feature flags) lives in +the closure while the dispatcher itself — and its poison state — is scoped +to one run. + +The legacy `with_hook_dispatcher(Arc)` adapter still exists +and intentionally preserves the old shared-state semantic for backward +compat: it wraps the supplied `Arc` in a closure that returns clones of the +same `Arc`, so a hook poisoned in run N stays poisoned for run N+1. New +call sites should reach for `with_hook_dispatcher_factory` for real per-run +isolation. + +Cross-run isolation is regression-tested in +`crates/ironclaw_reborn/tests/hooks_integration.rs`: +`per_build_dispatcher_state_does_not_leak_across_runs` installs a panicking +hook and proves that the inner port still never receives the call on build +2 (because the fresh dispatcher's slot is un-poisoned and re-applies the +fail-closed deny). `legacy_with_hook_dispatcher_shares_state_across_builds` +pins the shared-state semantic of the legacy adapter as the explicit +opt-in baseline. diff --git a/crates/ironclaw_reborn/src/loop_driver_host.rs b/crates/ironclaw_reborn/src/loop_driver_host.rs index 086c021b06d..b9e67877c18 100644 --- a/crates/ironclaw_reborn/src/loop_driver_host.rs +++ b/crates/ironclaw_reborn/src/loop_driver_host.rs @@ -915,6 +915,20 @@ fn host_runtime_error(error: HostRuntimeError) -> AgentLoopHostError { } } +/// Factory closure that produces an `Arc` for each host +/// build.

Project the matching `LoopHostMilestoneKind::Hook*` variants in `DurableLoopHostMilestoneSink` so hook telemetry now lands in the same durable event log as model/reply/loop milestones — SSE observers still see live hook events, and audit replay can reconstruct the full hook trail. - `ironclaw_events`: add hook variants to `RuntimeEventKind`, optional hook fields on `RuntimeEvent` (`hook_id`, `hook_point`, `hook_trust_class`, `hook_decision`, `hook_failure_category`, `hook_failure_disposition`), typed constructors (`hook_dispatched`, `hook_decision_emitted`, `hook_failed`), and dedicated sanitizers (`sanitize_hook_label`, `sanitize_hook_id`) re-run on every wire crossing. No new crate dependency edges; hook strings cross the boundary opaque. - `ironclaw_reborn::milestone_events`: project the three hook milestone kinds via a new `loop.hook` capability id. `HookDecisionSummary` is collapsed to its closed-vocabulary `kind_name()` so sanitized reasons never enter the durable substrate. - `ironclaw_event_projections`: extend `TimelineEntryKind` and the `RuntimeEventKind -> RunProjectionStatus` mapping so hook events are pure telemetry — they preserve the current run status rather than changing it. - Tests: 4 unit tests in `ironclaw_events::runtime_event::tests` (serde round-trip per variant + unsafe-label collapse), 3 in `ironclaw_reborn::milestone_events::tests` (projection per variant, including the assertion that raw `Deny { reason }` text does not reach the durable wire payload). Existing replay-projection direct-construction tests updated for the new RuntimeEvent fields.

charset=UTF-8 Content-Transfer-Encoding: 8bit Audit finding C3: extensions could declare `[[hooks]]` with `scope = "own_capabilities"` in their manifest, but the dispatcher never enforced it — an Installed hook from ext-A could fire against capabilities provided by ext-B. Scope was parsed but not load-bearing. This change makes scope load-bearing end-to-end: - `BeforeCapabilityHookContext` carries an optional `provider: ironclaw_host_api::ExtensionId` populated by the middleware. The hook context is `#[non_exhaustive]` already so this is non-breaking. - `HookBinding` gains `owning_extension: Option` and `scope: HookBindingScope`. `HookBindingScope` is `Global` / `OwnCapabilities` / `SameTenant`. Builtin and Trusted bindings default to `Global` and carry no `owning_extension`; Installed bindings carry both, sourced from the manifest. - `HookDispatcher::install_installed_*` installers now require the caller to pass `(owning_extension, scope)`. The registrar derives both from the manifest entry, so manifest authorship is the single source of truth. - A new `CapabilityProviderResolver` trait + bundled `NullCapabilityProviderResolver` lets the middleware lift the capability id to its provider at invocation time. The middleware wires the resolved provider into the hook context. - `dispatch_before_capability` consults `binding.scope.permits(...)` before invoking each hook. Bindings that don't permit the current invocation are inert — no sink call, no failure record, no poisoning. Conservative defaults: - When the provider resolver returns `None` (no resolver wired, or the capability has no known provider), `OwnCapabilities`-scoped hooks do NOT fire. An attacker cannot bypass scope filtering by stripping provider info from the descriptor. Tests: - 5 new dispatcher tests cover OwnCapabilities matching, foreign provider, unresolved provider, SameTenant, and Builtin Global. - 1 new registrar test asserts manifest scope and extension propagate into `HookBinding`. - 1 new middleware test asserts the provider resolver populates the hook context. - 1 new integration test in `ironclaw_reborn` proves an ext-A hook scoped to `OwnCapabilities` does not intercept invocations that have no resolved provider (the production composition default).

LSM had `commoncap` ordering bugs; K8S had webhook bypass via `--disable-admission-plugins`; CRX has had repeated permission-escalation flaws. **Type-level enforcement of "Installed cannot Allow" is the most defensible part of ICLAW's design and the part most underrepresented in prior art.** ✓✓ + +--- + +### Axis 3 — Attenuation (how privilege is restricted at registration) + +| Sys | Mechanism | +|---|---| +| LSM | None at registration — module is loaded with full LSM API surface | +| EBPF | Verifier rejects unsafe programs; helper-function allowlist per program type | +| ENVOY | proxy-wasm: ABI surface limits what filter can do; no attenuation beyond ABI | +| K8S | Webhook URL + resource selector in MutatingWebhookConfiguration; no attenuation of decision power | +| OPA | Policy bundles can be partitioned, but policies have full Rego power | +| CRX | Manifest permissions declared at install; user can revoke; some permissions runtime-prompted | +| VSC | None — extension has user-level privilege | +| TAURI | Permission set + scope (allowlist/denylist patterns) attached to capability grant | +| **ICLAW** | **Per-tier default attenuation + manifest-declared scope (`Global`/`OwnCapabilities`/`SameTenant`) enforced at dispatch + capability ↔ hook binding** | + +**Observation:** Tauri's permission+scope model is the closest analog. ICLAW adds the **tier-based default attenuation** layer on top — Installed hooks default to a smaller capability set than Trusted hooks, even before manifest-declared scope. + +**Divergence:** Manifest scope (`OwnCapabilities`) is enforced at *dispatch time* by filtering bindings against `ctx.provider`, not just at install time. Why: install-time-only enforcement (Tauri, K8S) is bypassable if any caller can construct a context without provider info. Dispatch-time enforcement defends against future internal callers that might not have known about scope. This was specifically codex audit finding C3. ✓ + +--- + +### Axis 4 — Decision vocabulary (what can a hook return) + +| Sys | Decisions | +|---|---| +| LSM | int return: 0=allow, -EPERM=deny; no mutate, no pause | +| EBPF | LSM hook return: 0=allow, negative errno=deny; tracing hooks return value ignored | +| ENVOY | StopIteration / Continue / SendLocalReply (synthesized response); can rewrite headers/body | +| K8S | Validating: Allowed/Denied + reason; Mutating: JSON Patch operations | +| OPA | `allow`/`deny` rules + violation messages; can return arbitrary structured decision | +| CRX | declarativeNetRequest: block/redirect/upgradeScheme/modifyHeaders/allowAllRequests | +| VSC | N/A — extensions act, they don't decide | +| TAURI | Allow / Deny via capability evaluation; no mutation | +| **ICLAW** | **`Allow` (Privileged only), `Deny`, `PauseApproval` (returns gate-ref for human approval), `PauseAuth` (returns gate-ref for auth), `Pass` (no opinion), `Patch` (mutators), `Effect` (observers, future)** | + +**Observation:** Most systems are allow/deny only. K8S adds mutation. ICLAW's `PauseApproval`/`PauseAuth` (returning a gate-ref instead of a binary verdict) is closest to **OAuth step-up authentication** in spirit — the hook can require an out-of-band user action before deciding. No system in this table has this exact primitive. + +**Divergence:** Pause-with-gate-ref is novel here. Why: agent loops have a human-on-the-side that synchronous syscall mediators (LSM) don't have. Routing a decision to the user is a real outcome, not an error. The risk is gate-ref forgery — addressed via `HookGateRefFactory`-minted UUIDs, but worth a property test that gate-refs are unguessable and one-shot. **TODO — add to threat model.** ⚠️ + +**Divergence:** `Pass` (no-opinion) as a first-class return distinct from `Allow`. LSM has no equivalent — every LSM either allows or denies. Why we diverge: with multiple hooks at a point, "I don't care" is genuinely different from "I bless this." OPA has the same shape (a deny rule that doesn't fire ≠ an allow rule that does fire). ✓ + +--- + +### Axis 5 — Failure semantics (panic, timeout, malformed return) + +| Sys | Panic/crash | Timeout | Malformed | +|---|---|---|---| +| LSM | Kernel panic (module bugs are catastrophic) | N/A — synchronous, no timeout | Compile-time prevented | +| EBPF | Verifier rejects unsafe; runtime division-by-zero etc. terminates program (treated as deny for LSM hooks) | Instruction limit | Verifier rejects | +| ENVOY | proxy-wasm: trap → filter disabled for connection | Configurable per filter; trap on exceed | ABI mismatch → trap | +| K8S | Webhook crash → `failurePolicy: Fail` rejects admission or `Ignore` proceeds | Configurable timeout; same `failurePolicy` applies | Same | +| OPA | Engine error → fail open or closed (deployment choice) | Configurable | Eval error | +| CRX | Service worker crash → restarted; ongoing request may not complete | declarativeNetRequest is declarative; no runtime per-rule | N/A | +| VSC | Extension crash → reported to user; affected commands fail | N/A | N/A | +| TAURI | Plugin panic → IPC call returns error; app continues | Per-command | N/A | +| **ICLAW** | **`catch_unwind` per hook; failure_policy matrix: Gate=FailClosed, Observer=FailIsolated, Mutator=FailIsolated, Effect=FailClosed; poison sticks for process lifetime** | **`tokio::time::timeout` per hook; same policy matrix** | **AttenuationViolation = FailClosed** | + +**Observation:** The `failure_policy` matrix — different defaults for different *kinds* of hooks at the same point — is unusual. K8S has a single `failurePolicy` per webhook config. Envoy has per-filter trap behavior but not differentiated by what the filter was doing. + +**Divergence:** ICLAW's "Gate failures FailClosed, Observer failures FailIsolated" is the right call: a crashed gate is unsafe (you can't tell whether it would have allowed), but a crashed observer just loses telemetry for one event. LSM gets this wrong (panic on bug = no syscall mediation at all). K8S gets this right but only on operator say-so. ✓ + +**Divergence:** Poison sticks for process lifetime. K8S retries failed webhooks per request. Why ICLAW diverges: in an agent loop, a hook that's panicking repeatedly is more likely buggy than transiently faulty, and retrying it makes the loop unobservable. The cost is operator action (process restart or hook reinstall) to recover. Worth documenting as a known property. ✓ (with doc nit) + +--- + +### Axis 6 — Isolation unit (where does the hook execute) + +| Sys | Unit | +|---|---| +| LSM | Same kernel address space — no isolation | +| EBPF | Same kernel, but verifier-bounded (no unbounded loops, no arbitrary memory) | +| ENVOY | proxy-wasm: per-filter wasm VM, sandboxed; native C++: same process | +| K8S | Out-of-process (separate webhook service), network-isolated | +| OPA | Sidecar process (typical) or in-process library (advanced) | +| CRX | Service worker (separate JS context); content scripts in page context with isolated world | +| VSC | Extension host process (separate Node.js process per workspace) | +| TAURI | In-process Rust plugin (trusted) or webview JS (sandboxed) | +| **ICLAW** | **In-process Rust** (Builtin/Trusted/Installed-predicate); **WASM sandbox** stubbed for Installed-WASM hooks | + +**Observation:** Out-of-process isolation (K8S, OPA, VSC) is the gold standard for buggy/untrusted hooks but adds latency + operational complexity. In-process with type-level sealing (ICLAW for now) is acceptable while hook authors are trusted; becomes a problem when third-party Installed hooks ship. + +**Divergence:** Installed-WASM execution is **stubbed** in v1; runtime Installed hooks are predicate-language only (no arbitrary code). Why: a typed predicate language is small enough to audit by hand (and is what we have); WASM execution adds wasmtime as a dependency surface and a new isolation boundary we'd want a separate threat model for. ✓ (deferred deliberately) + +--- + +### Axis 7 — Manifest / declaration + +| Sys | How hooks are declared | +|---|---| +| LSM | C registration call at kernel init | +| EBPF | BPF program loaded via syscall; attach point in syscall args | +| ENVOY | Static config or xDS; filter chain in listener YAML | +| K8S | `ValidatingWebhookConfiguration` / `MutatingWebhookConfiguration` CRDs | +| OPA | Policy bundles loaded from disk/HTTP/OCI | +| CRX | `manifest.json` at extension install | +| VSC | `package.json` `contributes` section | +| TAURI | `tauri.conf.json` permissions + per-capability `.toml` files | +| **ICLAW** | **`[[hooks]]` table in extension manifest with id, version, attach point, phase, priority, scope, body (Predicate \| Wasm), trust class derived from extension trust** | + +**Observation:** ICLAW's manifest shape is closest to **K8S `ValidatingWebhookConfiguration`** in fields (id, scope/selector, failure policy) and closest to **Tauri permissions** in being shipped *with the extension* rather than installed by the operator. This is the right hybrid for an agent runtime where extensions are user-installed but operate on user data. + +**Divergence:** `HookId` is content-addressed (blake3 of `extension_id || hook_local_id || hook_version || extension_version`). K8S uses operator-chosen names; CRX uses extension-id + listener-name. Why: content addressing makes duplicate-installation detection automatic, and it makes the milestone audit log uniquely identify the *exact bytes* of the hook that fired. Cost: hook IDs are 64-char hex strings, not human-friendly. ✓ + +--- + +### Axis 8 — Telemetry / audit + +| Sys | Audit substrate | +|---|---| +| LSM | audit subsystem (auditd) for `LSM_AUDIT_*` events; per-LSM optional | +| EBPF | perf ring buffer / bpf_trace_printk; Tetragon emits structured events to userspace | +| ENVOY | Access logs + stats; per-filter metrics | +| K8S | API server audit log records admission outcome | +| OPA | Decision logs (structured) — opt-in | +| CRX | None standardized; chrome://extensions logs | +| VSC | None standardized; extension can write its own | +| TAURI | None standardized | +| **ICLAW** | **`HookDispatched` / `HookDecisionEmitted` / `HookFailed` milestones on `LoopHostMilestoneSink`; projected into `RuntimeEvent::Hook*` for durable audit; L3 schema snapshots + L4 pairing-invariant matrix tests** | + +**Observation:** Most extension systems (CRX, VSC, Tauri) ship *no standard* audit substrate, which is one reason third-party extensions are hard to trust. The systems that *do* (OPA decision logs, K8S audit, Tetragon events) are the systems people trust for high-stakes deployments. ICLAW lining up with the *trusted-substrate* group is the right call. + +**Divergence:** Pairing-invariant matrix test (every dispatch outcome ⇒ exactly one Dispatched + one terminator). No prior-art system documents this property as a test. Why ICLAW has it: "LLM data is never deleted" project rule means hook decisions must be reconstructable from the event log alone; dropped or duplicated emissions break that property silently. ✓✓ + +--- + +## Where IronClaw stands out (vs prior art) + +1. **Type-level trust enforcement.** No survey system enforces "Installed cannot mint Allow" via sealed enum variants + tier-specific installers. The closest analog is Pony's reference capabilities — a different domain but the same insight that *unforgeable distinctions belong in the type system*. +2. **Phase-ordered dispatch with stable tiebreakers.** OPA has analogous ordering but only inside one engine; LSM has stacking but flat. ICLAW's phase layer externalizes ordering concerns from hook authors in a way few systems do. +3. **Dispatch-time manifest-scope enforcement** (not install-time only). +4. **Failure-kind matrix** (Gate=FailClosed vs Observer=FailIsolated at the same point). +5. **PauseApproval/PauseAuth as first-class decisions** with gate-ref minting. +6. **Pairing-invariant audit matrix** as a regression test, not just a design claim. +7. **Tenant-keyed predicate state** + per-build dispatcher (full tenant isolation for in-memory predicate counters). + +## Where IronClaw is conventional (and should be) + +1. **Phases (Validation→Authorization→Policy→Telemetry)** — same shape as Envoy filter phases and K8S admission stages. +2. **Allow/Deny + reason** — same as LSM, K8S, OPA. +3. **Mutator hooks emit patches** — same as K8S mutating admission. +4. **Manifest-declared attach point** — same as K8S, CRX, Tauri. +5. **Content-addressed identity** — same conceptual primitive as Git object IDs or OCI image digests. + +## Where IronClaw is conventional but **shouldn't** be (open questions) + +1. **In-process execution for Installed hooks.** K8S/OPA/VSC isolate untrusted code out-of-process; ICLAW keeps Installed hooks in-process and relies on predicate-language audit-by-hand for safety. This is fine while there's no Installed-WASM path. **Once Installed-WASM lands, revisit out-of-process or VM-per-extension isolation.** +2. **Sticky poison for process lifetime.** K8S retries; ICLAW does not. Right call for now, but document the failure mode for operators. +3. **No formal model of the dispatch invariants.** OPA has Rego semantics; LSM-BPF has the verifier. ICLAW has tests. A short typed-state-machine spec for dispatch (states: Idle → Dispatching → DecisionEmitted/Failed → Quiescent) would close the loop. **TODO — add to design doc.** +4. **No per-tenant rate limit on hook *installation*.** If an Installed extension can register N hooks, a malicious extension can flood the dispatcher. Cap N somewhere reasonable. **TODO — add to manifest validator.** + +## Where IronClaw diverges but the *why* is weak (review needed) + +1. **`HookDispatchOutcome` is not retriable.** Once a gate denies, the loop has no native primitive to retry-with-context — the user has to re-issue. K8S admission has the same property and it's broadly considered correct, so probably fine, but worth confirming this is what we want for agent loops specifically. +2. **No "soft deny" / "advisory" decision.** OPA distinguishes deny (block) from warn (annotate, allow). ICLAW collapses both into Deny + reason. If we ever want to surface "the policy is uneasy but didn't block," we'd need a new outcome. Probably correct to defer, but log it. +3. **Telemetry-phase observers run even on Gate denial.** Defended above (audit value); confirm with operators that this matches the mental model of "what fired during this turn." + +## Methodology notes + +- Survey was constrained to systems with a public design doc / source. Closed systems (proprietary RASP/EDR products) likely have closer analogs but aren't useful as cite-able prior art. +- Axes were chosen *after* drafting IronClaw's design, so the table is unavoidably colored by ICLAW's vocabulary. A second pass with axes chosen from one of the survey systems (e.g., K8S's admission-controller checklist) would be a useful adversarial check. +- Each row in the matrix should be independently verified against current docs — kernel/Envoy/K8S/OPA APIs all evolve, and this snapshot is May 2026.

Surfaces 7 prioritized follow-ups: - High: per-extension hook-count cap (D3/D4) - High: gate-ref unguessability + one-shot test (S1) - Med: resolver field-level scope (I2) - Med: per-evaluator state ceiling (D5) - Med: poison-stickiness operator runbook - Low: timing side-channel residual acknowledgement (I4) - Low: instruction-marker denylist periodic review (I5) Confirms the load-bearing 'Installed cannot Allow' (E1) property holds via type-level seal + tier-specific installers, backed by compile_time_seal_test and installed_binding_cannot_be_paired_with_ privileged_impl tests.

From 73507568a353af2b2ffb8fae2ac98fcfcd211764 Mon Sep 17 00:00:00 2001 From: Zaki Date: Wed, 13 May 2026 11:22:18 -0700 Subject: [PATCH 23/46] feat(hooks): close threat-model gaps S1 (gate-ref entropy) and D3/D4 (registration flood) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit S1 (gate-ref unguessability, factory side): - Three new tests on `UuidHookGateRefFactory`: - `gate_refs_are_v4_uuids` pins the v4 entropy source (122 random bits per ref per RFC 4122 §4.4); fails if a future change moves to a counter or weaker UUID version. - `gate_refs_have_no_collisions_across_many_calls` mints 20k refs across both namespaces, asserts zero collisions (statistical proxy for entropy quality). - `approval_and_auth_namespaces_do_not_overlap` confirms prefix routing separation. - Doc comment now documents the security property explicitly and delineates factory-side vs gateway-side responsibilities for the one-shot consumption property. D3/D4 (hook registration flood): - New `MAX_HOOKS_PER_EXTENSION = 32` and `MAX_HOOKS_PER_EXTENSION_PER_KIND = 8` consts in `registrar.rs`. - New `HookRegistrar::enforce_registration_caps` runs pre-flight at the top of `install()`, before any binding is inserted. Whole-batch rejection means a partially-installed batch cannot slip past. - Three regression tests: total-cap rejection, per-kind-cap rejection, at-cap acceptance. - Error messages cite the threat-model finding so operators can map rejection back to the design rationale. Threat model updated: S1, D3, D4 marked closed in the cross-cutting properties matrix and the open-follow-ups list. --- crates/ironclaw_hooks/docs/threat-model.md | 15 +- .../ironclaw_hooks/src/middleware/gate_ref.rs | 93 +++++++++++++ crates/ironclaw_hooks/src/registrar.rs | 129 ++++++++++++++++++ 3 files changed, 230 insertions(+), 7 deletions(-) diff --git a/crates/ironclaw_hooks/docs/threat-model.md b/crates/ironclaw_hooks/docs/threat-model.md index aad45d957bb..429c1754b19 100644 --- a/crates/ironclaw_hooks/docs/threat-model.md +++ b/crates/ironclaw_hooks/docs/threat-model.md @@ -62,7 +62,7 @@ Ranked by blast radius of compromise: | # | Vector | Adversary | Mitigation | Test/invariant | Residual | |---|---|---|---|---|---| -| S1 | Forge approval gate-ref to bypass `PauseApproval` | A1 | `UuidHookGateRefFactory` mints UUIDv4 gate-refs; gate-ref namespace is `gate:hook-approval-`; gate consumption is one-shot at the approval gateway | **Gap.** No test pins that gate-refs are unguessable or one-shot. **TODO** | High until tested | +| S1 | Forge approval gate-ref to bypass `PauseApproval` | A1 | `UuidHookGateRefFactory` mints UUIDv4 gate-refs (122 random bits per ref, RFC 4122 §4.4); gate-ref namespace is `gate:hook-approval-` vs `gate:hook-auth-`; one-shot consumption is the approval gateway's responsibility, not the factory's | `gate_refs_are_v4_uuids`, `gate_refs_have_no_collisions_across_many_calls` (20k draws), `approval_and_auth_namespaces_do_not_overlap` | Low (factory side); approval gateway one-shot is its own threat model | | S2 | Spoof `HookId` to impersonate another hook in audit log | A1/A2 | Content-addressed `HookId` (blake3 of length-prefixed fields including extension_id + hook_version); duplicate-id rejection at registry insert | `dispatch::tests::content_addressed_hook_id_test`; `registry::tests::duplicate_hook_id_rejected` | Low | | S3 | Spoof `ExtensionId` in `BeforeCapabilityHookContext.provider` to bypass scope filter | A3 | `provider` is `Option` populated by the *middleware*, not the hook; hook reads ctx but doesn't write it | Hook trait only exposes `&BeforeCapabilityHookContext`; ctx fields are not mutable from hook code (rustc-enforced) | Low | | S4 | Spoof envelope source in prompt patch (e.g., make hook-emitted patch appear as `Memory`) | A1/A2 | `wrap_untrusted(source, trust, body)` source is set by middleware based on patch origin; closed-vocabulary `EnvelopeSource` enum | `prompt_envelope::tests::source_is_caller_chosen` | Low | @@ -107,8 +107,8 @@ Ranked by blast radius of compromise: |---|---|---|---|---|---| | D1 | Slow hook hangs the loop | A1 | `tokio::time::timeout` per hook (configurable); Gate timeout → FailClosed (deny), Observer timeout → FailIsolated | `dispatch::tests::timeout_fails_closed_for_gate` | Low | | D2 | Panicking hook re-panics every call, exhausting log substrate | A1 | Poison sticks on first panic; subsequent calls short-circuit without invoking hook body | `registry::tests::poisoned_slot_skips`; same-dispatch poison re-check | Low | -| D3 | Extension installs N hooks to flood the dispatcher | A1 | **Gap.** No per-extension or per-tenant cap on hook registration count. **TODO** — add to manifest validator | Currently uncapped | High until fixed | -| D4 | Extension registers hooks at every attach point to slow every dispatch | A1 | Same as D3 | Same | High until fixed | +| D3 | Extension installs N hooks to flood the dispatcher | A1 | Pre-flight cap at registrar boundary: `MAX_HOOKS_PER_EXTENSION = 32` total per install batch; rejection is whole-batch so no partial install can slip past | `install_rejects_when_total_exceeds_per_extension_cap`; cap value pinned in `registrar.rs` const | Low | +| D4 | Extension registers hooks at every attach point to slow every dispatch | A1 | Pre-flight cap: `MAX_HOOKS_PER_EXTENSION_PER_KIND = 8` per attach-point per extension; tighter than the total cap because fan-out at one dispatch point is the actual blast radius | `install_rejects_when_per_kind_cap_exceeded`; `install_accepts_at_per_extension_cap` pins the at-cap boundary | Low | | D5 | Predicate evaluator unbounded memory growth (window state per tenant × capability × hook) | A1/A4 | Sliding-window eviction trims expired entries; **but** unbounded distinct tenants × hooks × capabilities is possible | **TODO** — add a hard ceiling per evaluator and a metric for eviction pressure | Med | | D6 | Approval gate-ref accumulation (PauseApproval emitted but never resolved) | A1 | Approval gateway has its own TTL on outstanding refs (separate subsystem); hook side just mints | Out of scope (depends on approval gateway) | Defer | | D7 | Audit-log flood from chatty observer hook | A1/A2 | Observer-failure-isolated means runaway observer doesn't fail the run; emission rate is bounded by dispatch rate | Low (bounded by user activity) | Low | @@ -139,17 +139,18 @@ These properties should hold across the framework.

Canonical 'rate-limit a capability' use case for the predicate language. 2. large-stake-approval-gate — Installed predicate hook, NumericSum over amount_usd field, PauseApproval at $1000/24h. Manifest-shape + registrar-install coverage from outside Reborn; end-to-end dispatch lives in ironclaw_reborn integration tests because NumericSum needs resolved args (a friction finding documented in the companion doc). 3. pii-redaction-warning — Trusted Rust hook implementing PrivilegedBeforePromptHook, injects a trusted instruction snippet reminding the model to redact PII. Demonstrates the path a system author takes when the predicate language isn't expressive enough. API change (F1 fix): SanitizedArguments::unresolved() promoted from pub(crate) to pub. This is the documented safe default — predicates that need args must fail closed against it — so exposing the constructor cannot weaken any trust property. The sanitizing from_json constructor stays sealed; that's the trust boundary. Without this fix, external hook authors could not construct a BeforeCapabilityHookContext with both a known provider AND unresolved args, which made TDD of their own predicate impossible. Findings documented in docs/real-hooks-findings.md, ranked by severity. Big-picture observation: writing the Trusted Rust hook (F4) was easier than writing the declarative predicate hook (F1 + F2 + F3) — three of seven findings target predicate-authoring ergonomics. The declarative path needs the most polish before third-party extension authors will trust it for non-trivial policy.

The only public +path was `new_unresolved(...)`, which sets `provider: None` — and +with `provider = None`, the FU1 scope filter (`OwnCapabilities`) +correctly drops the hook before predicate evaluation, making Hook 1 +look like a non-firing hook for the wrong reason. + +**Why this is friction:** A hook author writing predicate tests for +their own hook cannot reproduce the production dispatch shape (named +provider + unresolved args) without going through Reborn's middleware. +TDD of a predicate's match logic becomes impossible at the crate +boundary. + +**Fix:** Made `SanitizedArguments::unresolved` `pub`. The +`from_json` (sanitizing) constructor stays sealed — that's the trust +boundary. `unresolved` is the safe default and exposing it cannot +weaken any trust property: any predicate that needs args fails closed +against it. + +**Recommendation:** None remaining; done in this PR. + +--- + +### F2 — Manifest deny `reason` text is replaced by a closed-vocabulary label + +**What happened:** Hook 1's manifest sets +`OnExceededAction::Deny { reason: "daily place_order cap exceeded" }`. +At dispatch time, the decision-visible reason is the static label +`"hook_predicate_denied"`, not the manifest text. Same for +`PauseApproval` (`"hook_predicate_pause_requested"`). The manifest +text is preserved in audit milestones but never reaches the model. + +**Why this exists (per the existing code comment in +`installed_hook.rs::evaluate`):** Sinks take `&'static str` reasons +"to keep adversarial format!-built strings out of the seam." A +malicious Installed extension that controlled the deny reason could +inject prompt-text or pretend to be a system message. So the dispatcher +*intentionally* collapses dynamic reasons into a closed vocabulary +for the model-visible path. + +**Why this is still friction:** + +- It surprises hook authors who reasonably expect their manifest + reason to surface to the agent. The first test iteration of Hook 1 + asserted on the manifest text and failed. A hook author writing + end-to-end tests will hit the same wall. +- The closed vocabulary is currently undocumented at the public API + level. It exists only in a comment on a private method. +- Audit gets the rich text via `HookDecisionEmitted` / observer facts, + but a hook author has no obvious way to *see* that during dev + without standing up the milestone-sink wiring. + +**Recommendations:** + +1. Document the closed-vocabulary deny / pause-approval reasons in + the rustdoc of `OnExceededAction` and on `GateDecisionView`. A + hook author should learn this from `cargo doc`, not from a failing + test. +2. Consider adding `OnExceededAction::Deny { code: DenyReasonCode }` + alongside the freeform `reason` so authors can pick from a curated + vocabulary of model-visible codes. This would let predicate hooks + surface *useful* model-visible context without opening a freeform + string channel. +3. Add a one-line example to the predicate-hook docs showing how to + inspect the rich audit reason in a dev loop. + +--- + +### F3 — Hook 2 (NumericSum) cannot be exercised end-to-end from outside Reborn + +**What happened:** Hook 2 uses +`ValueOrRateBound::NumericSum { field: "amount_usd", ... }`. The +predicate needs *resolved* `SanitizedArguments` to evaluate the sum. +Resolved arguments require sanitization (`SanitizedArguments::from_json`, +sealed) plus a `CapabilityInputResolver` wired through middleware. +Both seams live in `ironclaw_reborn`. From a standalone +`ironclaw_hooks` test, the best a hook author can do is: + +- Validate the manifest (`entry.validate()`). +- Install through the registrar. +- Confirm that dispatch with unresolved args **fails closed**. + +The actual "the cap trips at $1000" behavior can only be asserted in +an `ironclaw_reborn` integration test +(`hooks_integration::numeric_sum_predicate_caps_total_value_against_real_inputs`, +which already exists). + +**Why this is friction:** A third-party extension author writing a +NumericSum hook has no way to TDD the *fire* condition without +either (a) depending on `ironclaw_reborn` as a dev-dep (heavy + the +extension probably shouldn't reach into Reborn at all), or (b) +faking the resolver in their crate, which requires the +`SanitizedArguments::from_json` constructor to be reachable. + +**Recommendations (pick one):** + +1. Expose a `SanitizedArguments::for_tests(serde_json::Value)` + constructor behind a `#[cfg(feature = "test-support")]` feature + flag. Extension authors opt in via dev-dep with the feature; + production code can't touch it. Preserves the sanitizer-only-on- + trusted-path property while removing the test-only blocker. +2. Ship a `MockCapabilityInputResolver` as part of `ironclaw_hooks`'s + public surface that takes a `serde_json::Value` and an opaque + transform fn, and runs the resolver+sanitize path under test + harness control. More machinery but doesn't require feature-gating. +3. Accept the friction and document that NumericSum hooks must be + integration-tested via `ironclaw_reborn`. Cheapest, but it's a + real barrier to adoption — declarative predicate hooks promised + "no need to depend on the runtime crate to author one." + +**Tentative pick:** (1). Lowest blast radius, clearest semantics. + +--- + +### F4 — Trusted Rust hooks at `before_prompt` work cleanly (no friction) + +Hook 3 was the easiest of the three to write. The trait surface is +small (`PrivilegedBeforePromptHook::evaluate` takes a context + a +sink), the sink is well-documented, and the type-level +trust-class enforcement was clear from compiler errors — when I +accidentally tried `RestrictedMutatorSink::add_trusted_snippet` (a +nonexistent method on the restricted sink), the compiler error was +informative. + +**The good:** + +- `PatchOrdinalHint::{Last, NearTop}` is a clear, small enum. +- `HookPatchView` projection is exactly what a test wants. +- Budget-aware bow-out (returning early when + `remaining_snippet_byte_budget` is too small) is idiomatic. +- `HookDispatcherBuilder::install_trusted_before_prompt(...)` chain + reads naturally. + +**No recommendations.** This is what the rest of the API should +feel like. + +--- + +### F5 — `HookId::derive` requires the crate's `identity::ExtensionId`, not `ironclaw_host_api::ExtensionId` + +**What happened:** A hook author already holds an +`ironclaw_host_api::ExtensionId` (the authoritative identifier). To +mint a `HookId` via `HookId::derive`, they need +`ironclaw_hooks::identity::ExtensionId` — a different newtype. +Conversion is a one-liner (`identity::ExtensionId(host_ext.as_str().to_string())`) +but the duplication surprises readers. + +**Why this exists:** The hash derivation type is a transparent string +newtype; the host-api type is validated and comparable. +`HookRegistrar` already does the mirroring internally. + +**Why this is friction:** Hook authors who build hook IDs by hand +(as Hook 3 does, because it's a Trusted in-process hook installed +directly without going through the registrar) have to know about both +types. Discoverability is poor — `cargo doc` shows two +`ExtensionId` types and the relationship isn't obvious. + +**Recommendations:** + +1. Add a `From<&ironclaw_host_api::ExtensionId>` impl for + `ironclaw_hooks::identity::ExtensionId`. One-liner, makes the + conversion ergonomic. +2. Document the relationship between the two types in the crate-level + rustdoc. + +--- + +### F6 — `HookManifestEntry` constructor is bare-struct-literal-only + +**What happened:** Hook 1 and Hook 2 each construct a +`HookManifestEntry` via a 7-field struct literal. There's no builder +and no `Default` impl. Adding a new optional field to the struct +would silently change behavior at every call site (because +`#[serde(default)]` makes the field optional at deserialization but +not at construction). + +**Why this is friction:** Friction-by-future-tense. The framework will +grow optional manifest fields (versioning, attribution, additional +scopes). Today's hook-author code becomes broken-by-omission tomorrow. + +**Recommendations:** + +1. `#[derive(Default)]` is not viable directly because of the inner + enums, but a `HookManifestEntry::new(id, kind, body)` constructor + with `..Default::default()`-style field overrides via a small + builder would isolate the surface. +2. Alternatively, mark `HookManifestEntry` `#[non_exhaustive]` and + provide a builder. `#[non_exhaustive]` forces external constructors + to go through a builder, which buys forward compatibility. + +--- + +### F7 — `HookPriority::DEFAULT` is the only easily-discoverable priority + +**What happened:** Building any of the three hooks, the natural +question is "what priority do I want?" The docs don't surface +guidance (e.g., "use `DEFAULT` unless you have a concrete reason; if +you do, here's the convention"). `HookPriority` exposes `DEFAULT` and +arithmetic; no named variants like `HIGH`, `LOW`, `LATE`. + +**Why this is friction:** A hook author guesses or copies. Two hooks +at the same priority order by hook-id (stable but author-opaque). +Result: subtle behavioral coupling. + +**Recommendation:** Add a short rustdoc example to `HookPriority` +explaining the priority space, the stable tiebreaker, and when to +deviate from `DEFAULT`. Optionally add named constants (`EARLY`, +`LATE`). + +--- + +## Summary + +| ID | Severity | Status | +|---|---|---| +| F1 — Sealed `unresolved()` blocks external dispatch tests | High | Fixed in this PR | +| F2 — Closed-vocabulary deny reason is undocumented | Med | Recommendation: rustdoc + `DenyReasonCode` | +| F3 — NumericSum can't be TDD'd outside Reborn | Med | Recommendation: feature-gated test constructor | +| F4 — Trusted Rust before_prompt hooks (no friction) | — | — | +| F5 — Two `ExtensionId` types are confusing | Low | Recommendation: `From` impl + doc | +| F6 — `HookManifestEntry` struct literal is fragile | Low | Recommendation: `#[non_exhaustive]` + builder | +| F7 — Priority guidance is missing | Low | Recommendation: rustdoc | + +**Big-picture observation:** Hook 3 (Trusted Rust hook) was easier to +write than Hook 1 (declarative predicate). That's surprising — the +predicate language was supposed to be the *easier* path. Three of the +seven findings (F1, F2, F3) target predicate-authoring ergonomics. +The declarative path needs the most polish before third-party +extension authors will trust it for non-trivial policy. + +## What this exercise did NOT cover + +- Predicate authors who'd use TOML rather than Rust struct literals. + The serialization round-trip is already tested in `manifest.rs`, + but typo / schema-mismatch ergonomics are a separate exercise. +- Hooks at `after_*` observer points (the dispatcher composes them + similarly to before_prompt; not exercised here). +- Hooks under load (timeouts, panics, contention).

Ergonomics findings: - F2 (closed-vocab deny reasons): rustdoc on OnExceededAction and GateDecisionView::Deny explaining the audit-vs-model split and why manifest reason text doesn't reach the model. - F3 (NumericSum can't be TDD'd outside Reborn): new test-support feature flag with SanitizedArguments::for_tests(value) that external hook authors can opt into via dev-dep. - F5 (two ExtensionId types): added From<&ironclaw_host_api::ExtensionId> impl for identity::ExtensionId, plus cross-link rustdoc. - F6 (HookManifestEntry struct-literal fragility): added #[non_exhaustive] + HookManifestEntry::new(id, kind, body) + with_scope/with_phase/with_priority/with_description/with_requires_grant builder methods. Migrated 3 external call sites in tests/. - F7 (priority guidance): rustdoc on HookPriority with when-to- deviate guidance, named FIRST/LAST constants documented for Builtin/Telemetry use cases. Tests: 151 unit + 1 + 6 integration in ironclaw_hooks all pass with --all-features. ironclaw_reborn (13 hooks_integration scenarios) unchanged. Threat model updated: I2 / D5 / poison runbook marked closed in both the per-vector table and the cross-cutting properties matrix. Open follow-ups now down to two Low items (I4 timing side-channel residual, I5 instruction-marker denylist refresh) plus the deferred DenyReasonCode enum from F2. --- crates/ironclaw_hooks/Cargo.toml | 9 + .../ironclaw_hooks/docs/operator-runbook.md | 227 ++++++++++++++++++ .../docs/real-hooks-findings.md | 12 +- crates/ironclaw_hooks/docs/threat-model.md | 14 +- crates/ironclaw_hooks/src/evaluator.rs | 116 +++++++++ crates/ironclaw_hooks/src/identity.rs | 25 ++ crates/ironclaw_hooks/src/kinds/gate.rs | 19 ++ crates/ironclaw_hooks/src/manifest.rs | 56 +++++ crates/ironclaw_hooks/src/ordering.rs | 37 +++ .../ironclaw_hooks/src/points/capability.rs | 38 ++- crates/ironclaw_hooks/src/predicate.rs | 22 ++ .../tests/foundation_pipeline.rs | 19 +- crates/ironclaw_hooks/tests/real_hooks.rs | 40 ++- 13 files changed, 578 insertions(+), 56 deletions(-) create mode 100644 crates/ironclaw_hooks/docs/operator-runbook.md diff --git a/crates/ironclaw_hooks/Cargo.toml b/crates/ironclaw_hooks/Cargo.toml index 9a31de3193c..b946e8be11d 100644 --- a/crates/ironclaw_hooks/Cargo.toml +++ b/crates/ironclaw_hooks/Cargo.toml @@ -5,6 +5,15 @@ edition = "2024" publish = false description = "Reborn loop hook framework: trust-tiered points/kinds/decisions, sealed witness types, dispatcher contract." +[features] +default = [] +# Exposes test-only constructors (e.g., `SanitizedArguments::for_tests`) that +# bypass the resolver wiring.

Where this doc says "see +> threat-model finding X", look up the finding for the design +> rationale. + +## 1. A hook poisoned (sticky failure) + +### What you'll see + +- `RuntimeEvent::HookFailed { hook_id, category, .. }` events for a + specific `hook_id` followed by silence: the hook isn't invoked + again, but capability invocations still flow. +- Audit log shows `HookDispatched` for the hook stops appearing after + the first failure event, even though the hook is still registered. + +### Why this happens (by design) + +The dispatcher implements **sticky poison**: when a hook panics or +trips its failure-policy category (timeout, malformed decision, +attenuation violation), the hook's registry slot is marked poisoned +and the dispatcher *skips* it for the remainder of the process's +lifetime. This is a deliberate divergence from K8s admission webhooks +(which retry per-request). The reasoning is in `prior-art.md` (Axis +5): in an agent loop, a repeatedly-panicking hook is more likely +buggy than transiently faulty, and retrying it makes the loop +unobservable. + +### Recovery options, ranked + +1. **Per-build dispatcher (preferred — no operator action).** The + factory pattern (`with_hook_dispatcher_factory`) constructs a + fresh dispatcher per host build. A new run picks up a fresh + dispatcher with no poison carried over. If your deployment already + uses `with_hook_dispatcher_factory`, the next run recovers + automatically. +2. **Process restart.** If the deployment uses the legacy + `with_hook_dispatcher` (single shared `Arc`), the poison persists + across runs. Restart the process to clear it. This is acceptable + for deployments where runs are short and restart is cheap. +3. **Reinstall the offending extension.** If the hook is misbehaving + for a structural reason (manifest schema drift, predicate + regression, manifest-window parse failure), update the extension + to a fixed version and reinstall. Reinstallation re-derives a + different `HookId` (extension version is hashed in), so the new + binding is fresh and the old poisoned slot becomes irrelevant. +4. **Disable the extension.** Last resort — drop the extension from + the manifest list. The lost functionality is the cost of the + buggy hook. + +### What you should NOT do + +- **Do not manually clear the poison.** There is no API for it, by + design. A poisoned hook indicates a real failure; clearing without + fixing the cause re-introduces the failure. +- **Do not retry the same `HookId`.** Re-installing the same extension + version produces the same content-addressed `HookId` and the + registry still has the poison. + +### Detecting the situation + +- Alert on `HookFailed` events with `category` other than + `AttenuationViolation` (which is usually a code-level bug rather + than runtime). +- Alert on a sustained gap between `HookDispatched` event rate and + registered-hook count — poisoned hooks register but never dispatch. + +--- + +## 2. Predicate evaluator approaches its state ceiling (D5 pressure) + +### What you'll see + +- `PredicateEvaluator::evictions_observed()` counter advances. +- Hooks at high-cardinality attach points (many tenants, many + capability names, many distinct hook ids) start producing + intermittent fail-closed decisions where they used to allow. +- No `HookFailed` events — the eviction is silent at the hook level. + +### Why this happens (by design) + +The predicate evaluator caps both history maps at +`MAX_HISTORY_KEYS = 8192` (per map). When a new `(tenant × +capability × hook × field)` key arrives at the cap, the LRU entry +(the key whose oldest retained timestamp is earliest) is evicted. +The cap defends against unbounded growth across permutations +(threat-model D5). + +### What an eviction *means* + +The evicted key's rolling window is lost. The next invocation +matching that key starts fresh at count=0 or sum=0. For +`InvocationCount` predicates this is a *partial bypass of the rate +limit* — the malicious case is an attacker who can produce many +distinct keys (by varying tenant id, for instance) to force eviction +of a key they want to flood. + +For `NumericSum` predicates the same applies: rolling sums are +forgotten when their key is evicted. + +### Recovery options + +1. **Confirm the eviction pressure is benign.** A counter that ticks + slowly under legitimate growth (new tenants, new capabilities) + doesn't indicate compromise. A counter that spikes during a + specific workload window is the signal to investigate. +2. **Audit incoming traffic for tenant-key cardinality.** If a + single source is producing thousands of distinct tenant ids, that + itself is a security event regardless of the eviction. +3. **Reduce hook density per attach point.** Per-extension caps + (`MAX_HOOKS_PER_EXTENSION_PER_KIND = 8`) bound new installs but + don't shrink an existing install. Audit installed extensions for + redundant hooks. +4. **Increase `MAX_HISTORY_KEYS` if legitimate workload growth has + genuinely outgrown the default.** This is a code change, not a + runtime knob — the cap is a const. Bumping it 2–4× is reasonable; + any larger jump should come with an analysis of why the + per-extension cap (D3/D4) isn't already constraining growth. + +### What you should NOT do + +- **Do not flush the evaluator manually.** Throwing away the entire + history map is much worse than letting LRU run: it resets *every* + active counter, including legitimate workload's. + +### Detecting the situation + +- Alert when `evictions_observed()` advances by more than 0 in a + rolling 1-hour window. The baseline should be exactly zero in + steady state. +- Dashboard the counter alongside per-extension hook counts and + per-tenant traffic. + +--- + +## 3. Hook registration is rejected at install time + +### What you'll see + +- Extension install fails with `HookError::RegistryConstruction` + citing one of: + - "per-extension cap" (threat-model D3) + - "per-kind cap" (threat-model D4) + - manifest validation error (typically scope/grant mismatch or + bad window) + +### Recovery + +These are by-design rejections. The extension author has either: + +1. Declared too many hooks (over `MAX_HOOKS_PER_EXTENSION = 32`) — + refactor to fewer hooks (most extensions need 1–5; reaching the + cap indicates a design issue). +2. Stacked too many hooks at one attach point (over + `MAX_HOOKS_PER_EXTENSION_PER_KIND = 8`) — same advice. +3. Declared `SameTenant` scope without the required grant — surface + the grant in the install UX. +4. Used an unparseable window string — see the error message for + the bad value. + +### What you should NOT do + +- **Do not raise the caps to ship a specific extension.** The caps + exist to bound blast radius. An extension that hits them is + evidence of either a design problem in the extension or an attack; + in either case, raising the cap is the wrong answer. File an + issue against the extension. + +--- + +## 4. Approval gate-ref consumed but the user didn't act + +### What you'll see + +- A `PauseApproval` decision was emitted (audit shows + `HookDecisionEmitted` with summary `PauseApproval`). +- The corresponding gate-ref (`gate:hook-approval-`) appears + in your approval gateway's outstanding-ref list, but no resolution + event has arrived. + +### Recovery + +This isn't a hooks-framework concern — gate-refs are minted by the +factory but consumed and timed-out by the approval gateway (see +threat-model finding S1 on the factory/gateway split). The hook +framework's responsibility ends at minting an unguessable gate-ref. + +Follow the approval gateway's own runbook for stale gate-ref +resolution. + +--- + +## 5. General debugging + +### "I want to see what a hook decided" + +The model-visible `GateDecisionView` carries only the closed-vocabulary +label (`hook_predicate_denied` etc.). The rich manifest-supplied +reason is in the audit log: + +``` +RuntimeEvent::HookDecisionEmitted { hook_id, summary, .. } +``` + +Query the event store by `hook_id` (the 64-char blake3 hex) to see +the per-dispatch trace. + +### "I want to know which extension owns a hook" + +`HookBinding.owning_extension` is set from the manifest at install +time. The registrar logs the mapping. For a content-addressed +`HookId`, the extension can be recovered by replaying +`HookId::derive` candidates against installed extensions — or just +look at the install logs. + +### "I want to disable hooks temporarily" + +Construct the host with the legacy `with_hook_dispatcher` taking an +empty `HookDispatcherBuilder::new(HookRegistry::new()).build_arc()`. +No hooks are registered; no dispatch happens.

HookedLoopPromptPort now requires a HookPromptMaterializationSink and fails closed if patches are emitted without one. The reborn factory installs an InstructionStoreBackedHookSink adapter that delegates to the host's InstructionMaterializationStore, so synthetic msg:hook.* refs are resolvable by the downstream model resolver. New seam trait (HookPromptMaterializationSink) keeps ironclaw_hooks decoupled from LoopRunContext. Critical #2 — OwnCapabilities hooks were inert in production wiring. Factory now installs SurfaceBackedProviderResolver (consults the visible-capability surface for capability_id → provider). With this, ctx.provider is populated and OwnCapabilities-scoped Installed hooks actually fire against their own provider's capabilities. Critical #3 — gate refs were unresolvable. Middleware default switched from UuidHookGateRefFactory to FailClosedHookGateRefFactory. Tests must explicitly opt into UUID (via with_gate_ref_factory) to exercise the affirmative ApprovalRequired path; production deployments must install a router-backed factory. New factory method RebornLoopDriverHostFactory::with_hook_gate_ref_factory. Concerning #5 — AfterModel fired twice + before durable finalization. Removed AfterModel dispatch from HookedLoopModelPort; the transcript port's finalize_assistant_message is now the sole AfterModel boundary (the durable one). Model port wrapper is preserved as a no-op shim for symmetry + future model-response-observed point. Concerning #7 — doc tidy: - CLAUDE.md: 3 trust classes → 4 (Builtin/Trusted/Installed/SelfAuthored with explicit note that SelfAuthored is run-scoped only and not loadable from an external source). - operator-runbook.md: "Audit log" → "durable runtime event stream" where the projection is actually the runtime-event stream, not formal AuditEnvelope records. - prior-art.md: poison-lifetime nuance — per-host-build with the factory pattern, process-lifetime only for the legacy adapter. - prior-art.md:80: trailing whitespace removed.

New `HookDispatcherBuilderFactory` signature: factory returns a HookDispatcherBuilder, and `RebornLoopDriverHostFactory` attaches a `RunScopedHookMilestoneSink` keyed to the CURRENT run's LoopRunContext inside `build_text_only_host_with_capabilities`, before sealing the dispatcher. The previous zero-arg signature relied on the closure capturing run_context — silently misattributed across reuses; new public API `with_hook_dispatcher_builder_factory` removes that failure mode entirely. Legacy `with_hook_dispatcher_factory` retained for back-compat (its sink-wiring contract stays caller-side). Concerning #6 — TimelineEntry hook metadata. Added 6 optional fields to `TimelineEntry` (hook_id, hook_point, hook_trust_class, hook_decision, hook_failure_category, hook_failure_disposition) and projected them from `RuntimeEvent::Hook*`. Replay consumers now see which hook fired/failed, not just that some hook event happened. Each field is closed-vocabulary (no free-form reason text — that stays in the audit reason payload, not the product replay DTO). Testing gaps from henrypark133 — caller-level tests: #4 (two-run hook telemetry attribution): hook_telemetry_attribution_is_per_run_not_captured Builds two hosts from the SAME builder factory closure with two fresh LoopRunContexts. Asserts each run's hook milestones carry its OWN run_id (no stale captured one). #6 (replay projection contract for hook events): hook_runtime_events_project_with_sanitized_hook_metadata non_hook_runtime_events_project_with_no_hook_metadata Constructs RuntimeEvent::Hook{Dispatched,DecisionEmitted,Failed} and asserts the projection preserves the metadata fields. The negative test guards against cross-contamination on non-hook events.

From 251ae78517f6a5dbccd16344a91d9542d4668cfc Mon Sep 17 00:00:00 2001 From: Zaki Date: Thu, 14 May 2026 06:29:40 -0700 Subject: [PATCH 30/46] feat(hooks): DenyReasonCode + PauseReasonCode closed-vocabulary enums MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Address real-hooks ergonomics finding F2 (deferred from PR #3573). The prior dispatcher collapsed every Installed-tier deny to the static label 'hook_predicate_denied', because manifest reason strings are author-controlled and surfacing them to the model would open a prompt-injection channel. The cost: the agent couldn't tell *why* a hook denied. This PR introduces two closed-vocabulary enums: - DenyReasonCode: Generic / RateLimit / ValueCap / Blocklist / RequiresApproval / OutOfPolicy - PauseReasonCode: Generic / RequiresApproval / OverThreshold / SensitiveAction Each variant has an as_label() returning &'static str (so the sink's &'static str contract is preserved). New OnExceededAction variants 'DenyWithCode { code, reason }' and 'PauseApprovalWithCode { code, reason }' let manifest authors opt into the richer labels while keeping reason audit-only. The legacy Deny { reason } / PauseApproval { reason } variants are retained for back-compat and map to DenyReasonCode::Generic / PauseReasonCode::Generic — existing manifests continue to produce hook_predicate_denied / hook_predicate_pause_requested. Threat-model regression: a hook author cannot smuggle text into the model-visible label because the 'code' field is typed as the enum; there's no String slot exposed model-side. A test (deny_with_code_only_exposes_enum_variants_to_model) documents this as a compile-time property. Tests (+7 new = 161 total): - deny_reason_code_labels_are_stable: pins the label vocabulary so rename/relabel is loud. - pause_reason_code_labels_are_stable: same for PauseReasonCode. - deny_with_code_round_trips_through_json + pause variant: wire round-trip + snake_case tag assertion. - deny_with_code_only_exposes_enum_variants_to_model: compile-time property check. - rate_or_value_cap_with_deny_code_routes_to_code_label: end-to-end affirmative test that the dispatcher emits the code's label. - rate_or_value_cap_with_pause_code_routes_to_code_label: same for pause.

The registry silently accepted Installed bindings with `HookBindingScope::OwnCapabilities` at points (BeforePrompt, AfterModel, AfterCheckpoint) whose dispatch context carries no per-capability provider. The manifest's declared scope had no effect at all — the hook fired against every dispatch. Reject the binding at install time so the operator sees the misconfiguration. 2. `dispatch_observer_at` for `AfterCapability` did not consult the binding's scope, so an Installed observer registered with `OwnCapabilities` fired against every invocation regardless of provider. Add `dispatch_observer_at_with_provider` carrying the resolved capability provider; the capability-port middleware resolves the provider once per invocation and threads it through both the BeforeCapability hook context and the AfterCapability observer dispatch. The dispatcher then enforces `HookBindingScope::permits` on each observer binding. `ObserverHookContext` gains a `provider: Option` field; `#[non_exhaustive]` keeps existing authors compiling.

The `HookDecisionEmitted` milestone therefore carried only the closed- vocab label, and operator-visible audit/SSE context was silently lost end-to-end. The fix splits the channels: - Model sees the closed-vocab label (`hook_rate_limit`, `hook_pause_over_threshold`, ...) via `sink.deny(label)`. This channel is unchanged. - Audit/SSE sees the manifest's free-form `reason` via a new audit-only sink method `record_audit_reason(reason: String)`. The recording sink captures it; the dispatcher reads it after the hook returns and threads it into `LoopHostMilestoneKind::HookDecisionEmitted`. Surface changes: - `PrivilegedGateSink` / `RestrictedGateSink` gain `record_audit_reason(String)` — accepts dynamic `String` (audit-only, no model-facing seam) unlike the `&'static str` decision reasons. - `RecordingGateSink` gains an `audit_reason: Option` field. - `GateHookOutcome::Decision` is now `Decision { decision, audit_reason }`. - `HookDispatcher::emit_decision_with_audit` threads the audit reason into the milestone. - `LoopHostMilestoneKind::HookDecisionEmitted` gains a `#[serde(default, skip_serializing_if = "Option::is_none")]` `audit_reason: Option`. The durable RuntimeEvent projection intentionally drops this field — audit reasons are operator-facing in-memory SSE content, never durable cross-process surface. Tests: - `deny_with_code_records_audit_reason_separately_from_model_label`: asserts the recording sink ends with `Deny { reason: "hook_rate_limit" }` in `state` AND `audit_reason == Some("daily cap of $1000 ...")`. --- crates/ironclaw_hooks/src/dispatch.rs | 43 ++++++++++--- crates/ironclaw_hooks/src/installed_hook.rs | 63 ++++++++++++++++++- crates/ironclaw_hooks/src/sink.rs | 26 ++++++++ .../ironclaw_reborn/src/milestone_events.rs | 24 ++++--- .../src/run_profile/milestones.rs | 24 ++++++- 5 files changed, 160 insertions(+), 20 deletions(-) diff --git a/crates/ironclaw_hooks/src/dispatch.rs b/crates/ironclaw_hooks/src/dispatch.rs index ab00b36020d..8044010a699 100644 --- a/crates/ironclaw_hooks/src/dispatch.rs +++ b/crates/ironclaw_hooks/src/dispatch.rs @@ -90,7 +90,15 @@ pub struct BeforeCapabilityDispatchOutcome { #[derive(Debug)] pub(crate) enum GateHookOutcome { Pass, - Decision(BeforeCapabilityHookDecision), + Decision { + decision: BeforeCapabilityHookDecision, + /// Free-form audit-only reason set by the hook via + /// [`crate::sink::PrivilegedGateSink::record_audit_reason`] / + /// [`crate::sink::RestrictedGateSink::record_audit_reason`].

A manifest could declare `requires_grant = "anything"` and get a cross-extension binding for free. Fix: `HookRegistrar` now carries a `verified_grants: HashSet` (empty by default — default-deny). Add the host-facing setter `with_verified_grants(...)`. At `install_one`, if `entry.requires_grant` is `Some(g)`, require `g ∈ verified_grants` or reject with a clear error. Tests: - `install_rejects_same_tenant_without_verified_grant` - `install_rejects_same_tenant_when_verified_grants_mismatch` - The existing positive test `installer_propagates_owning_extension_and_scope_from_manifest` now wires the verified grant explicitly (proves the API contract). **P1 #2 prompt_port.rs:150 — zip misalignment** The materialization loop zipped surviving messages against the ORIGINAL unfiltered patch list. `wrap_patches_to_messages` skips metadata patches and over-budget snippets, so the zip silently paired message[0] with patch[0] even when patch[0] was the skipped metadata — materializing the wrong content (or none) under the snippet's synthetic ref. Fix: `wrap_patches_to_messages` now returns `Vec` — surviving messages paired with their content by construction. The caller materializes `entry.safe_content` under `entry.message.content_ref` directly; no zip against unfiltered input. Removed the now-unused `safe_content_for_patch` helper. Test: - `materialization_stays_aligned_when_metadata_patches_are_filtered`: a hook emits `[metadata, snippet]`; asserts only one model message, and the materialized content under its ref contains the snippet's body — proves filtering can no longer desync from materialization. **P2 #3 loop_driver_host.rs:1343 — `with_hook_dispatcher_builder`** Docs said it deferred `build_arc()` to let the host factory finalize wiring; the implementation called `build_arc()` eagerly and routed through the legacy shared-dispatcher adapter, losing per-run dispatcher isolation and the run-scoped milestone sink. Fix: marked `#[deprecated]` with a note pointing callers to `with_hook_dispatcher_builder_factory(|| ...)` for per-build isolation, or `with_hook_dispatcher(...)` if they actually meant the shared adapter. The method body is unchanged so no callers break; they'll see the deprecation warning. No internal callers exist, so the deprecation doesn't trip `-D warnings`.

The wrapper then appended `msg:hook.*` messages to `bundle.messages`, so the downstream model request hit `grant.messages != messages` and failed closed with "model request messages do not match the host-built prompt bundle". Add `with_bundle_authority(authority, run_context)` and re-issue the grant after appending hook messages so it covers the post-hook bundle. Reborn wires `prompt_authority.clone()` + `run_context.clone()` into the wrapper at construction time. P2 — observer installer accepts non-observer points (dispatch.rs): `install_observer` accepted any `HookPointSpec` (including `BeforeCapability` / `BeforePrompt`) and only populated the observer map. Dispatch later found a binding without a gate/mutator impl and fail-closed the capability with "binding present without installed implementation". Reject non-observer points at install time so misuse fails loudly rather than poisoning bindings at dispatch. P2 — batch path skipped AfterCapability observers on inner error (capability_port.rs): The batch loop used `?` directly on `self.inner.invoke_capability(...)`, which propagated the error before dispatching `AfterCapability` observers. Failed batch entries disappeared from telemetry / audit, while the single-invocation path dispatches observers on error. Capture the inner result, dispatch observers, then propagate the error.

New `telemetry::sanitize_audit_reason` strips control characters and caps length at 512 bytes; `emit_decision_with_audit` routes the manifest- supplied reason through it before publishing milestones. Manifest validation also rejects reasons over the same byte limit at install time so the wire-side cap is a defense-in-depth layer, not the only line. - Make hot dispatch O(H) instead of O(H^2). The per-binding poison recheck used to acquire the registry mutex and walk every binding; `ordered_bindings_with_poison_snapshot` now takes the active bindings and the poisoned hook-id set under a single lock, and each loop threads a local `HashSet` that absorbs mid-dispatch poisoning. Removed the redundant `is_poisoned` helper. - Gate `HookDispatcher::registry_for_test` behind `cfg(any(test, feature = "test-support"))`. The accessor previously exposed `&Mutex` in production, letting any `Arc` holder lock and call `HookRegistry::poison` to disable installed hooks. Added `active_bindings_snapshot(point)` as the read-only production-safe replacement. - `#[serde(deny_unknown_fields)]` on every hook-manifest and predicate DTO (`HookManifestEntry`, `HookManifestBody`, `WasmBudget`, `HookPredicateSpec`, `CapabilityPredicate`, `ValueOrRateBound`, `OnExceededAction`). Typoed or unsupported fields (e.g. a manifest-supplied `trust_class`) now fail loud at install time instead of being silently dropped. - Bound predicate trees at install. New `validate_predicate_tree` enforces `MAX_PREDICATE_DEPTH = 8`, `MAX_PREDICATE_NODES = 64`, `MAX_PREDICATE_STRING_BYTES = 256`, and `MAX_MANIFEST_REASON_BYTES = 512`. A hostile registry manifest can no longer install a deep or huge `All`/`Any` tree that the evaluator would recursively walk on every match. - Cap sliding-window samples per key. `MAX_SAMPLES_PER_KEY = 4_096` in the predicate evaluator. Both the invocation-count and numeric-sum histories drop the oldest sample once the cap is reached, bounding memory under attacker-triggered hot capabilities while preserving rate/value-cap semantics over the most recent window. - `split_indexer` / `resolve_path` now fail closed on malformed bracket syntax (`amount[foo]`, `amount[`, trailing garbage). Previously they silently fell back to the parent field, which could let a typoed `NumericSum` predicate evaluate against the wrong value and allow calls the predicate would otherwise have denied. - Honor `PatchOrdinalHint`. `WrappedHookMessage` carries the source patch's `ordinal_hint`; `HookedLoopPromptPort` inserts `NearTop` messages after the bundle's `identity_message_count` and appends `Last` messages at the end. Safety/policy snippets that need early placement now get it. - Update `ironclaw_hooks` top-level docs to reflect the four trust classes (`Builtin`/`Trusted`/`Installed`/`SelfAuthored`) and the now-wired Reborn middleware composition. Tests added: - `manifest::rejects_unknown_top_level_field` - `manifest::rejects_unknown_wasm_budget_field` - `manifest::rejects_predicate_tree_exceeding_max_depth` - `manifest::rejects_predicate_tree_exceeding_max_nodes` - `manifest::rejects_predicate_string_exceeding_max_bytes` - `manifest::rejects_manifest_reason_exceeding_max_bytes` - `points::capability::malformed_indexer_returns_none_not_parent_value` - `telemetry::sanitize_audit_reason_*` (truncate / strip control / preserve / empty) `cargo fmt`, `cargo clippy --all --benches --tests --examples --all-features`, and `cargo test -p ironclaw_hooks` all pass clean.

charset=UTF-8 Content-Transfer-Encoding: 8bit * perf(hooks): restore batched capability dispatch when hooks active Follow-up to PR #3573 addressing a deferred HIGH refactor: the hook capability-port middleware previously downgraded `invoke_capability_batch` into N sequential `invoke_capability` calls whenever any hook was installed. Functional behavior was correct, but every batched call lost its O(1) inner-port semantics the moment a hook was registered, turning bulk dispatch into a per-entry round-trip. This change keeps a two-phase dispatch path: Phase 1 — preflight: walk invocations in order, run `BeforeCapability` hook dispatch for each, and translate restrictive decisions (deny / pause / fail-closed) into outcome slots immediately. Allowed entries are queued for the inner port. A hook-issued suspension still honors `stop_on_first_suspension` and short-circuits preflight, matching the previous sequential semantics. Phase 2 — inner batch: forward the surviving (hook-allowed) invocations to the inner port as a SINGLE `invoke_capability_batch` call, then splice its outcomes back into their original index positions. The inner port's own early-stop on suspension is honored: any queued entry without a corresponding inner outcome is dropped, matching the pre-refactor break-out semantics. `AfterCapability` observers continue to fire per merged entry in original index order, preserving the per-entry telemetry contract established in PR #3573 (serrrfirat finding #3). When the inner batch errors, observers fire for every preflight-resolved entry before the error propagates — keeping failed batch entries visible to telemetry, the same invariant the previous code maintained per-entry. The inner `LoopCapabilityPort` API is unchanged; this is a middleware- local refactor. No downstream crates were touched. Regression coverage (three new tests): - `batch_invocation_remains_batched_when_no_hooks_deny` — inner port sees exactly one batched call, not N sequential - `batch_invocation_filters_denied_entries_and_preserves_index_mapping` — partial denial keeps remaining entries batched in one call, with merged outcomes returned in original index order - `batch_invocation_dispatches_after_capability_observer_per_entry` — observer fires N times even though inner port is called once Refs #3573. Co-Authored-By: Claude Opus 4.7 (1M context) * ci: bump wasmtime 43.0.2 -> 44.0.2 for RUSTSEC-2026-0149 Fixes cargo-deny advisory failure: wasmtime path_open(TRUNCATE) bypassed FilePerms::WRITE host restriction in 43.x. 44.0.2 is the minimum patch that contains the fix. Bumps top-level and crate-level pins (ironclaw_wasm, ironclaw_wasm_sandbox_core, ironclaw_wasm_product_adapters) and refreshes Cargo.lock.

PR #3573 review (MEDIUM) flagged this as deferred — the live install path mirrored validation via `ironclaw_host_api::ExtensionId`, but the newtypes themselves did not enforce their own invariants, so any non-installer construction site (in-process Trusted hooks, hand-built derive() inputs, deserialized manifest data) could smuggle malformed IDs into the blake3 content- addressing hash. Make the inner field private, route construction through validated `new()` constructors with `TryFrom` / `TryFrom<&str>` impls, and gate `serde::Deserialize` via `#[serde(try_from = "String")]` so manifest deserialization fails closed on invalid input. Validation grammar mirrors `validate_name_segment` in `ironclaw_host_api::ids`: - non-empty - max 128 bytes - lowercase ASCII letter/digit start - only `[a-z0-9_.-]` - no `..` or empty dot segments New `InvalidIdentity` error enum (`thiserror`) surfaces specific violation reasons. The `From<&ironclaw_host_api::ExtensionId>` impl preserves the host→identity mirror path; the registrar now uses `(&extension).into()` directly. Construction-site migration: - ~60 call sites updated to `::new(...).expect("valid ... in test")` (test-data) or `(&host_ext).into()` (production registrar path) - two test fixtures had to be re-keyed to legal IDs: `c3-own-A`/`c3-own-A-self` → lowercase, and a `path::module` HookLocalId synthesized for collision testing → `path.module` (the colon was never a legal identifier under any documented rule) Co-Authored-By: Claude Opus 4.7 (1M context) * ci: address fmt + clippy + no-panics Three CI gates were failing on this branch: - "No panics in production code": the `From<&ironclaw_host_api::ExtensionId> for ExtensionId` impl in `crates/ironclaw_hooks/src/identity.rs` had a newly-added `.expect()`. The round-trip is infallible by construction (both validators mirror `validate_name_segment` in the host-api crate), but the no-panics scanner cannot prove that. Annotate the `.expect()` with the `// safety:` suppression the scanner honours, and back the infallibility claim with `extension_id_from_host_api_round_trips_grammar_corners`, a new test that walks every documented grammar corner so the two validators cannot silently drift apart without a test failure. - cargo-deny: RUSTSEC-2026-0149 (wasmtime WASI `path_open(TRUNCATE)` bypasses `FilePerms::WRITE`) is a freshly-published advisory unrelated to this PR. The IronClaw WASM sandbox does not grant guest modules WASI filesystem capabilities backed by host-controlled `FilePerms` — guests communicate via explicit host functions — so the TRUNCATE bypass is not reachable from our guest surface. Ignore in `deny.toml` with a comment that flags it for removal once wasmtime is upgraded. - "Code Style (fmt + clippy)": this is an aggregator job that fails whenever any of `no-panics`, `deny-check`, etc. fail. The underlying `Formatting` and `Clippy (all-features)` checks were already passing. Resolved transitively by the two fixes above. No behavior change: the `.expect()` was always unreachable in practice, the deny ignore is documentation-only, and the new test is pure verification.
