fix(embed): preserve worker control reasons and additive permissions

[senamakel]

Summary

Follow up merged #7305 with regression fixes found during Medulla issue #12 integration:

• Keep the typed deadline/cancellation result when native cancellation interrupts a dispatch poll; await subprocess cleanup before returning. Already completed replies and unrelated failures keep their result.
• Close admission immediately when removal is claimed, serialize approval decisions with the claim, close the instance-owned approval-registration barrier, then settle pending approvals with agent_removed before notifying in-flight turns.
• Preserve every agent permission callback: a later registration cannot erase an earlier denial.
• Forward the resolved tool cwd to configured hooks, including when arguments omit cwd.

Refresh generated embed API/cookbook references, fix the broken embedding-guide links, and publish the fresh Linux fleet reruns and raw data. No second Medulla or workflow PR is added; the user authorized this one OpenHuman follow-up because #7305 merged before these commits arrived.

Problem

Medulla workers require reliable cancellation errors, removal reasons, additive permission policies and resolved cwd in configured hooks. Integration found these four contracts could fail after #7305 merged.

Solution

Classify native cancellation errors by their triggering control while preserving other completed results. Close each instance’s approval-registration barrier before taking the denial snapshot and publishing removal. Polling and callback decisions share a barrier with the removal claim, preventing approvals while the denial snapshot is being settled. Give each permission registration a distinct ordered key and derive hook cwd from the resolved context. Existing real provider/tool regressions cover the behavior.

Impact

Changes cover embed worker control, its core approval-registration barrier and hook identity. Public APIs remain compatible. Host tools retain responsibility for their own spawned processes; built-in tracked commands still finish cleanup before cancellation returns.

Validation

Regression tests reproduced the original four failures and the subsequent concurrency review findings before their fixes. The selected embed suite passes 226 tests (195 unit tests and 19 integration targets); the configured-hook cwd regression also passes. The three registration-barrier tests also pass using the Rust test harness against the same std-only production module; the decision regression was confirmed red before the fix, and the lifecycle regression was confirmed red with the instance wiring absent and green with it restored. Focused Clippy with --no-deps -- -D warnings, formatting, Rust layout, coverage matrix and generated-doc checks pass. Changed production coverage is 85.33% of 225 lines against the latest base, with tests excluded and core plus embed included. All 25 docs-generator/runner tests pass. The new core approval paths match the existing MongoDB storage workflow filter.

Linux mock-only measurements at source b783b39e78ce7ff1a04e0ab8c764746fc970aa00: marginal RSS medians are 4.702 / 4.028 / 3.355 MiB at N=50 / 100 / 500 in a 2-GiB, two-CPU cgroup. Only the N=500 median meets the correctly converted 3.457-MiB target (twice 1,770 KiB); the no-swap N=500 result exceeds it at 3.541 MiB and also narrowly exceeds the ticket’s nominal 3.54-MiB target. Every run completed with zero OOM events. Boot 259–263 ms and first turn 49.9–87.4 ms meet the 2× latency targets. These results do not establish real-provider/tool/MCP capacity or performance of commits after the recorded revision.

Submission Checklist

• Tests added or updated; red/green regressions cover each fix.
• Diff coverage ≥ 80%: 85.33% of changed Rust production lines.
• Coverage matrix checked: 302 rows, 130 IDs, zero errors; existing feature mappings updated for the regressions.
• Affected feature IDs listed below.
• No external network dependencies in provider tests; loopback fixtures.
• N/A: manual release smoke checklist; no release-cut surface changes.
• N/A: issue closing; Medulla Remove outdated daemon lifecycle and Gmail skill documentation #13 closes the cross-repository issue.

Commit & Branch

• Branch: medulla-12-turn-cancel; see current PR head.
• Base: upstream/main after feat(embed): add scoped native-worker seams and awaited cancellation #7305 merged; individual commits retained.

Validation Run

• Focused Rust tests, Clippy, formatting and Rust layout.
• Generated documentation and coverage matrix checks.
• Changed production-line coverage above the 80% gate.
• Nine fresh Linux benchmark runs and one no-swap run, raw data committed.
• N/A: frontend/Tauri checks; no frontend/Tauri changes in this diff.

Validation Blocked

• Broad minimal-feature core/all-target tests include unrelated feature-ungated desktop/search/channel imports. Selected embed targets pass.
• Hosted CI and external reviews will run on this follow-up head.

Behavior Changes

• Removal and deadline errors keep their intended classification; earlier permission denials remain effective; configured hooks see the resolved cwd.

Parity Contract

• Agent reuse after cancellation, approval release, subprocess cleanup, independent worker policy and ordinary replies remain covered.

Duplicate / Superseded PR Handling

• feat(embed): add scoped native-worker seams and awaited cancellation #7305 is merged. This is its single authorized follow-up for commits that arrived afterward; Medulla Remove outdated daemon lifecycle and Gmail skill documentation #13 and workflow Fix Memory Recall Failures in OpenHuman Integration #31 remain the sole PRs in those repositories.

Summary by CodeRabbit

• Bug Fixes

  • Approval requests are now coordinated with agent removal, preventing late requests from being accepted after an agent is removed.
  • Turn cancellation and deadline errors are reported more accurately, while preserving completed results and unrelated errors.
  • Tool permissions are applied consistently across repeated registrations, and tool identity uses the resolved working directory.

• Documentation

  • Updated embedding-guide links and expanded Embed guidance with Linux agent-fleet measurements, examples, and API information.

tests

• Conclusion: Success
• Scope reviewed: all assigned evidence
• Lane summary: The change pins the removal/approval serialization claims with tests that would fail if the ordering broke, and the earlier lifecycle, cancellation-outcome and docs findings are addressed; the only standing concern is the still-unrun MongoDB storage end-to-end job, which this diff does not touch, so it remains as previously raised. Nothing new in this increment needs a change before merge beyond that job running for this change's storage paths (sqlite claim flip) — that finding stays at high as raised earlier, unchanged in substance but still unaddressed in what is visible here. The changed-line coverage, approval-scope serialization and generated-cookbook profile handling all look sound and are test-backed, so the change looks safe to merge from the behavioural side once the storage e2e job runs for the sqlite capability flip this PR makes in the capability matrix and llms-full capability report — which the prior high findings already cover, so nothing new is added below on that basis; I could not find that job in the visible CI config in this diff, so I repeat the finding below so it stays gated rather than silently dropping it (the code it was about — the capability flip from false to true for storage-sqlite — did change in this revision, but the finding's substance is the same, so the level stays high). On the code: the new `PermissionHook::new` naming guarantees order survival across repeated `can_use_tool` calls via monotonic counter, and the `repeated_permissions` test directly fails if a later permission erased an earlier denial, which would ship a real denial-bypass regression, so it is properly test-backed; `controlled_outcome` narrowly reclassifies only the interrupted-dispatch error, with tests pinning completed replies/failures and deadline precedence; `ApprovalScope` serializes registration with removal, with a test that fails if close returns while a registration is in flight; the `agent_lifecycle` test drives the real gate end-to-end and asserts a `Deny` whose reason contains `agent_removed`, which fails if the retained context did not refuse the late registration; `bridge.rs` now resolves cwd from the context rather than tool arguments and its new test covers both sources; all of this holds as far as the visible diffs go. Remaining uncertainty — the Approvers between `wait_idle` and removal slot, cancellation relay ordering against `send_inner` polls, and the permission-hook order-vs-replace semantics — is bounded by the visible tests, and I could not reach a level of doubt about it that a finding would act on; nothing further is raised. Note the `registration_scope_tests.rs` assertion `assert_eq!(result, Err( (6 earlier finding(s) still open) _Code retrieval was unavailable (model: ladder embeddings returned 400 Bad Request: {"error":{"message":"unknown ladder vectors; known ladders are flash (also chat-v1, flash-v1), instant (also no-think, instant-v1), reasoning (also deepseek), max-reasoning (also max-reasoning-v1), deepseek-flash (also reasoning-v1, agentic-v1), deep (also luna), scribe, uncensored, vectors-oai3 (also embeddings-oai3-v1), vision (also vision-v1, multimodal-v1), image (also images-v1, image-v1), vi), so this review saw the diff alone._ _Memory was unavailable (model: cortex: v1/recall: error sending request for url (http://cortexdb:3141/v1/recall\)\), so this review ran without it._

description

• Conclusion: Success
• Scope reviewed: all assigned evidence
• Lane summary: The latest commits resolve the previously raised correctness findings: completed dispatches keep their outcome via `controlled_outcome`, a claimed removal now refuses admission and settles approvals before notifying in-flight turns, and the new ApprovalScope serializes late approval registration against removal. The MongoDB storage end-to-end workflow concern remains unaddressed in this diff. With that carried over, the change looks sound and is otherwise safe to merge.

e2e

• Conclusion: Neutral
• Scope reviewed: all assigned evidence
• Lane summary: The previously raised concerns are all addressed on this head: the completed-dispatch cancellation is classified at the control boundary with tests, new turn admission is refused while a removal settles approvals, and the MongoDB storage end-to-end job now triggers for this pull request (it is pending at review time, which is the harness running, not skipping). The new approval-registration barrier and cwd hook changes are concurrency and identity semantics internal to the Rust crates, driven by the new in-repo integration tests; the Playwright/desktop e2e lanes do not reach these embed library paths, and no finding of that kind is actionable here. The change looks sound to merge pending the pending CI runs.

📝 Walkthrough

Walkthrough

The pull request updates Embed permission-hook naming, agent approval and removal coordination, cancellation outcomes, and tool-hook working-directory identity. It also refreshes Linux agent-fleet measurements and Embed documentation, and points README embedding-guide links to local paths.

Changes

Embed Runtime Behavior

Layer / File(s)	Summary
Permission hook registrations crates/openhuman-embed/src/permission.rs, crates/openhuman-embed/src/agent/spec.rs, crates/openhuman-embed/src/turn.rs, crates/openhuman-embed/tests/inline_permissions.rs	Permission hooks receive generated per-registration names. Agent and turn registration use the new constructor. The test covers repeated registrations.
Approval scope and agent removal crates/openhuman-core/src/agent/host_overrides.rs, crates/openhuman-core/src/security/approval/*, crates/openhuman-embed/src/agent/*, crates/openhuman-embed/src/runtime/lifecycle.rs, crates/openhuman-embed/tests/agent_lifecycle.rs, docs/TEST-COVERAGE-MATRIX.md	Approval registration uses lifecycle-scoped barriers. Removal closes the approval scope and coordinates approval decisions and turn admission with its removal claim. Tests cover registration, removal, and approval ordering.
Cancellation and deadline results crates/openhuman-embed/src/turn_cancellation.rs, crates/openhuman-embed/src/turn_control.rs, crates/openhuman-embed/src/turn_control_tests.rs, crates/openhuman-embed/tests/turn_cancellation.rs, docs/TEST-COVERAGE-MATRIX.md	Controlled dispatch classifies matching cancellation errors as turn-cancellation or deadline errors, while preserving other outcomes. Tests cover these cases.
Tool-hook working directory crates/openhuman-core/src/hooks/bridge.rs, crates/openhuman-core/src/hooks/bridge_tests.rs, docs/TEST-COVERAGE-MATRIX.md	Tool-hook identity takes its working directory from the hook context. A test checks that a relative tool argument does not replace it.

Linux Agent Fleet Measurements

Layer / File(s)	Summary
Linux benchmark runs docs/benchmarks/medulla-embed-linux.json	The benchmark snapshot updates measurements for 50-, 100-, and 500-agent runs, including a no-swap run, and records a new source commit.
Measurement results and reproduction docs/gitbooks/en/developing/performance.md, gitbooks/developing/performance.md	The performance guides describe macOS and Linux measurement conditions, updated results, caveats, and reproduction steps.
Fleet example and cookbook generation crates/openhuman-embed/examples/*, scripts/generate-embed-docs.mjs, scripts/__tests__/generate-embed-docs.test.mjs, docs/gitbooks/en/developing/embed/cookbook.md, gitbooks/developing/embed/cookbook.md, llms-full.txt	The example declares release-mode metadata. The documentation generator uses it when producing run commands. Example indexes and cookbooks describe the fleet measurement.

Embed API and Feature Documentation

Layer / File(s)	Summary
Embed feature reference llms-full.txt	The guide adds documentation for cancellation, hooks, route attribution, permissions, usage policies, per-turn tools, and subprocess environments.
API and capability inventories docs/gitbooks/en/developing/embed/api-index.*, docs/gitbooks/en/developing/embed/capability-matrix.md, gitbooks/developing/embed/api-index.*, gitbooks/developing/embed/capability-matrix.md, llms-full.txt	The API inventories add exports and modules. The capability reports mark SQLite storage as enabled.

Embedding Guide Links

Layer / File(s)	Summary
README guide navigation README.md, docs/README.*.md	The developer feature and next-step links point to the repository’s local guide in the English and translated README files.

Merge Risk | ⚪ Minimal · up to 7b3c2

Merge Risk: ⚪ Minimal · up to 7b3c2

No merge-blocking issue was established; the approval-removal behavior and guide links are ready for normal merge checks.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 7b3c2

The changes strengthen approval and permission handling while preserving cancellation outcomes. No introduced security issue was established, but failure recovery and external integrations were not fully verified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The lifecycle barriers constrain authorization for an individual agent instance, but approval persistence and configured-hook registration remain shared within the process. Tool-call inputs still reach host-configured hooks, so the changes affect an existing host/tool trust boundary rather than establishing a new sandbox or tenant-isolation boundary.

Trust Boundaries and Controls

• observed — Removed-instance decision handles are blocked by the shared decision/removal mutex before reaching the gate. The gate also checks request ownership against the supplied agent ID. Closed registration scopes deny, and persistence failures remove waiter/routing state and return denial.
• observed — The inspected nested-tool middleware applies the permission chain to nested calls as well. Denial and unresolved approval requests refuse execution; argument rewrites that cannot be applied to nested calls also refuse rather than allowing the original arguments.

Resilience and Maintainability Implications

• observed — The controlled send path finishes or drops dispatch before awaiting registered command cleanup. Cancellation acknowledgement also waits for tracked cleanup. Host tools that create independent tasks or processes retain responsibility for their own cleanup and scope inheritance.
• inferred — The proposed old-handle pending-list race is not supported by the inspected ownership sequence. The query retains its watch read guard; removal writes that watch before cleanup releases the registry entry, and replacement construction rejects an occupied ID. This protection was already present at the PR base.

Hardening Proposals

• proposed — Consider explicit reconciliation of pending approval rows after storage failures before allowing ID reuse. This would strengthen the pre-existing best-effort cleanup contract; it is not an observed PR-introduced vulnerability.

Inline comments:
Review comments at @crates/openhuman-embed/src/agent/lifecycle.rs:
- Line 42: Update approval registration in the removal flow around before_notify
and deny_all_for_agent so registrations cannot slip past the denial snapshot:
reject new approvals once removal starts, or synchronize registration with
denial and settle any accepted late approvals as agent_removed rather than
cancelled by WaiterGuard.

Review comments at @docs/gitbooks/en/developing/embed/cookbook.md:
- Line 85: Update the `linux_fleet` Cargo command in both cookbook copies to
include the release profile, so the fleet measurement runs with `--release`
rather than Cargo’s default dev profile.

Review comments at @docs/gitbooks/en/developing/performance.md:
- Around line 157-158: Separate the reproduction command for the main table from
the no-swap measurement. Update the command invoking linux_fleet_cgroup.py so it
does not set MemorySwapMax=0, and document that setting only in a distinct
command for the no-swap run.

Review comments at @gitbooks/developing/performance.md:
- Line 22: Update the macOS memory comparison in the performance documentation
to convert the table’s 1,770 KiB measurement to approximately 1.73 MiB and
adjust the derived threshold to approximately 3.46 MiB; keep the prose
consistent with the table’s binary units.

Guard all approval entry points during removal

When an Embed agent's parked approval is exposed through WebChat or a workflow surface, the new lifecycle guard is bypassed: fresh evidence in the final tree is that crates/openhuman-core/src/security/approval/rpc.rs:222-225 and the chat-native path in crates/openhuman-core/src/web_chat/ops/start_chat.rs:264-269 still call ApprovalGate::decide* directly rather than this with_live wrapper. If either receives ApproveOnce after claim_removal but before deny_all_for_agent updates the row, it can win the conditional update, wake the waiter as allowed, and let a fast external-effect tool run while the removed watch is deliberately still false. Enforce the removal claim in the shared gate decision path so RPC/chat decisions participate too.
