Design preference: a **DB-observable signal** so cancellation survives across the async + boundaries already used by the orchestrator, consistent with the DB-backed approval model (Rule 5). +2. **Observation points:** the loop checks the signal at **state boundaries** — before `DECIDING` and + before `TOOL_EXECUTING`. This bounds worst-case cancellation latency to one tool execution. +3. **In-flight tool:** a running `execute_command` subprocess is terminated via the **existing sandbox** + `SandboxProcess.terminate()`/provider terminate (`provider.py:45-48,187-207`) — no new mechanism. +4. **`terminate()` becomes real:** it sets the signal (and triggers the in-flight sandbox kill); the + loop transitions `CANCELLING → CANCELLED`, persists a final checkpoint + audit, and returns + `cancelled`. +5. **Wiring (the missing link):** the orchestrator's agent branch (`orchestrator.py:210-216`) and the + **timeout path** must invoke `terminate()` — today they never do. The scheduler/timeout integration + reuses `resolve_execution_timeout` (already honored by Hermes `execute_command`, `hermes.py:119`). + +## 5. Heartbeats & timeouts + +- Heartbeat stays as-is (`hermes.py:291-299`) — real per-step `last_heartbeat`. +- **Timeout** becomes a real terminal state (`TIMED_OUT`) when the configured budget (wall-clock via the + ADR-010 timeout, and/or the configurable step bound, Cap 19) is exceeded — replacing the silent + `max_steps` stop that currently reports success. + +## 6.

Today all + collapse to `COMPLETED` + exit `0`. (→ lifecycle-design.) +3. **Planning?** Goal-derived, advisory, revisable; the plan artifact becomes *real* (generated) not + decorative. (→ capability-model.) +4. **Search?** Behind a `SearchProvider` abstraction (runtime-abstraction rule); the canned response + becomes a **test double only**; production wires a real provider, subject to sandbox network policy + (cross-track). (→ tooling-design.) +5. **Resume?** Reconstruct trajectory from the already-persisted `agent_steps` + last checkpoint, then + continue — mirroring the existing `resume_research_run`/`resume_briefing_run` precedent. (→ + recovery-design.) +6. **Cancellation?** Cooperative: a cancellation signal observed at loop boundaries; `terminate()` sets + it and is **wired into the orchestrator + timeout path**; in-flight subprocess killed via the sandbox. + (→ lifecycle-design.) +7. **Checkpoints write-only → recoverable?** Define the recovery contract; resume reads the latest + checkpoint for `workflow_id` for plan/cursor and `agent_steps` for trajectory (no schema change + needed at design level). (→ recovery-design.) +8. **Experimental requires:** no prod mock; real exit status; real search; structured tool-calls; + goal-derived plan; tests covering the real-LLM branch. (Honesty achieved; full lifecycle safety may + still be partial.) +9. **Pilot requires:** Experimental **plus** wired+tested cancellation, working+tested resume, + sandbox-confined file tools (R-05), fail-fast init, configurable step budget, and one audited real + governed run producing genuine output. (Honest **and** lifecycle-safe **and** contained.) +10. **Intentionally deferred:** multi-agent/hierarchical coordination; dependency-graph/advanced + replanning; new tools beyond the existing set; per-step Discord streaming; non-OpenRouter backends; + full **Production Ready** status. v1.1.0 targets **Experimental→Pilot only**. + +## 5.

(→ boundary-model, provider-resolution.) +2. **What must fail closed?** Unknown/misspelled provider; missing Docker when isolation is required; + incoherent/unsafe sandbox config at startup; any policy the selected provider cannot enforce. (→ + provider-resolution, security-policy.) +3. **Startup validations?** A lifespan sandbox-config gate (mirroring the A-001 owner gate, + `api.py:67-82`): probe Docker when required; abort on unknown provider; emit a loud audit + warning + for any explicit host-unsafe mode. (→ security-policy.) +4. **Provider resolution?** Explicit known-provider map; **unknown → raise** (remove the + `else→Local` fail-open); availability-checked; validated at startup **and** execute-time. (→ + provider-resolution.) +5. **Runtime containment enforcement?** Containment = the Docker boundary; the `SandboxPolicy` is + **honored or the run fails closed** (no decorative pass); Local is reclassified as *explicitly unsafe, + opt-in only*. (→ runtime-containment, security-policy.) +6. **Hermes file tools participation?** File tools route through the same containment/path-confinement + boundary; owned by Track S, consumed by Track H — single resolution in `R-05-shared-resolution.md`. +7. **Pilot Safe constitutes:** default-secure; fail-closed resolution; startup validation; enforced + policy (or fail closed); file tools confined; audit complete (already true). +8. **Intentionally deferred:** full Production-Safe hardening (seccomp/AppArmor, rootless, image + signing); non-Docker backends (gVisor/Firejail); OS-level "genuinely restricted local mode"; network + egress filtering beyond `--network none`. v1.1.0 targets **Pilot Safe** only. + +## 5. Design principles + +- **Safe by default, unsafe by explicit choice** — invert the current default; host execution becomes a + deliberate, audited opt-in, never a silent fallback. +- **Fail closed, never fail open** — every ambiguity (unknown provider, missing Docker, unenforceable + policy) refuses rather than degrades to host. +- **Reuse the chokepoint** — all containment changes happen behind the existing single + `SandboxManager.execute` seam that all runtimes already use (Rule 9).

A non-enforcing provider (`local`) is allowed only as a deliberate choice and is **declared** + — `sandbox.created` audit carries `policy_enforced=false` and startup emits a loud + `sandbox_host_unsafe_at_startup` warning.

Objective & boundary + +**Objective:** eliminate simulation from the Hermes production path and make outcomes truthful, so the +runtime earns **Experimental** under the `ADR-hermes-v1.1-foundation` gate — while preserving the sound +skeleton (governance, persistence, registry, real file/command tools) AP-105 §4 told us not to lose. + +**Boundary (Architecture Rules 1–10):** no change to governance, approval, scheduler, memory schema, +event taxonomy, or the runtime-abstraction contract beyond the minimum a listed gap requires. No new +tools (the five stay: `web_search`, `read_file`, `write_file`, `execute_command`, `finish`). No new +agent types, model backends, or migrations. + +**H-2 implementation target = the six P0 items** (`H-2-gap-prioritization.md` §2). P1 (terminate, +resume, fail-fast init, budget) and P2 are designed here but built in H-3…H-5. + +## 2. The honest execution model (target) + +A real Hermes run: `validate_goal` (governance, unchanged) → **PLANNING** (model derives a plan *from the +goal*) → loop[ **DECIDING** (model emits a *structured* `ToolCall`) → **TOOL_EXECUTING** (real tool incl. +real search) → observe honest `ToolResult` → persist step+checkpoint+heartbeat (unchanged plumbing) ] → +terminal state (**COMPLETED / FAILED / TIMED_OUT / CANCELLED**) → **real exit status** → persist +artifacts. No mock branch, no canned observation, no always-`0` exit. (`H-1-hermes-master-design.md` Q1; +state machine in `H-1-hermes-lifecycle-design.md` §2.) + +## 3. The ten required answers (explicit) + +### Q1 — How `AsyncMock` is removed from production paths +- **Delete** `from unittest.mock import AsyncMock` (`hermes.py:7`) and the entire `is_mocked` decision + block (`hermes.py:198-223`). The production loop keeps **only** the real-model branch + (`hermes.py:224-246`), upgraded to structured parsing (Q… below). +- **Where the simulation goes:** into **tests**, injected through the *existing constructor seam*. Today + `HermesRuntimeAdapter.__init__` already accepts `openrouter_client` (`hermes.py:29-42`); tests pass a + **fake client** (a plain object/`Protocol` impl returning canned completions) instead of an in-module + `AsyncMock`. A new `SearchProvider` seam (Q2) is injected the same way. +- **No silent downgrade:** with the mock branch gone, a missing/invalid key cannot quietly become canned + behavior — it surfaces via fail-fast init (P1-3) or a real error. A **guard test** asserts + `unittest.mock` is not imported by `hermes.py`. +- **Order:** the fake-client + `SearchProvider` test doubles must exist before the branch is deleted, or + the 4 existing `test_hermes.py` tests (which run through the mock path) break. Sequenced in + `H-2-implementation-plan.md`. + +### Q2 — How real search is introduced via `SearchProvider` +- Define a **`SearchProvider` port** — a minimal protocol `search(query: str) -> list[result]` — + resolved by **constructor injection**, mirroring `openrouter_client` (Rule 2; `H-1-hermes-tooling-design.md` + §3). New module e.g. `nexus/execution/runners/search_provider.py` (additive; no schema). +- `_execute_tool`'s `web_search` branch (`hermes.py:84-94`) calls `self.search_provider.search(query)` + instead of returning canned text. The **canned text becomes a test double** behind the same port, + relocated to tests (kills Cap 8 "simulated search in prod"). +- **Production provider choice is an impl-AP decision** (an HTTP search/retrieval backend, or reuse of + the OpenRouter-backed `intelligence/research.py` path). H-2 fixes only the **abstraction + injection + seam**, not the vendor. +- **Egress governance (cross-track, already decided):** real search does network I/O. Per + `R-05-shared-resolution.md` §6, search egress must obey the active sandbox network policy — under + `network=none` it runs as an explicitly control-plane-governed (host) action **or** is disabled; never + a hidden in-container egress (Rule 9). H-2 consumes this rule; Track S owns it. + +### Q3 — How goal-derived planning replaces decorative plans +- Remove the hardcoded literal (`hermes.py:159-163`). In **PLANNING**, one model call derives an initial + plan **from the goal**; it is stored as the existing `agent_plan` artifact (`hermes.py:357-365`, + unchanged schema) and is **advisory & revisable** — it informs/records intent but never a hardcoded + script (`H-1-hermes-capability-model.md` Pillar A). The loop may revise it from the trajectory. +- Target tier: Cap 2 Simulated → **Partially Implemented** (Experimental). Advanced dependency-graph + replanning is **P2**. + +### Q4 — How exit status becomes truthful +- `execute_goal` returns an `exit_code`/`status` **derived from the real loop outcome**, not a constant. + Terminal mapping: genuine `finish` → `0`/COMPLETED; unrecoverable error / `ToolResult.ok=false` + aggregate → non-zero/FAILED. The current swallow-exception-as-finished path (`hermes.py:254-259`) is + replaced by a real FAILED transition; failed steps persist with a non-COMPLETED `ExecutionStatus` + (instead of always `COMPLETED.value`, `hermes.py:269`). +- **No orchestrator change needed for Experimental:** `orchestrator.py:227` already maps + `exit_code != 0 → ExitStatus.FAILURE`. The new TIMED_OUT/CANCELLED *distinctions* (beyond + SUCCESS/FAILURE) are **P1** and may add **additive** enum values (impl-AP-decided; no schema redesign). +- Also fix the summary artifact's hardcoded `exit_code: 0` (`hermes.py:385`) to the real value. + +### Q5 — How `terminate()` becomes functional (designed; P1) +- **Cooperative cancellation** (`H-1-hermes-lifecycle-design.md` §4): `terminate()` sets a + **DB-observable** cancel signal on the existing `ExecutionRecord` (no schema redesign — a status/flag + using existing columns or an additive enum value, impl-AP-decided). The loop checks the signal at + **state boundaries** (before DECIDING and before TOOL_EXECUTING), bounding latency to one tool + execution; an in-flight `execute_command` is killed via the **existing** `SandboxProcess.terminate()` + (`provider.py:47-50`). +- **Wiring (the missing link):** the orchestrator agent branch (`orchestrator.py:210-216`) and the + timeout path invoke `terminate()` — today they never do. Loop transitions CANCELLING → CANCELLED, + persists a final checkpoint+audit, returns `cancelled`. +- **Not in H-2's implementation slice** (Experimental); built in **H-4** (lifecycle). + +### Q6 — How checkpoint recovery becomes resumable (designed; P1) +- Add `resume_goal(execution_id)` (`H-1-hermes-recovery-design.md` §3): (1) load all `AgentStepRecord` + rows ordered by `step_index` → rebuild `self.trajectory`; (2) load latest `WorkflowCheckpointRecord` + for `workflow_id == execution_id` → restore `self.plan` + cursor; (3) `step_index = max+1`; (4) + re-enter the loop at the **CHECKPOINTED** boundary; re-validate the goal through governance first. +- **Pure read over existing data → no schema change.** Resume **fails closed** on absent/inconsistent + data (never silently restarts). Mirrors `resume_research_run`/`resume_briefing_run` (one resume idiom, + Rule 7). Automatic orphan-triggered resume is **P2**; v1.1.0 ships resume as *invocable*. +- **Not in H-2's implementation slice;** built in **H-4** (recovery). + +### Q7 — How existing Runtime V2 boundaries remain intact +- **Adapter contract preserved.** Hermes stays an `AgentRuntimeAdapter` (`base.py:84-95`); `validate_goal` + + `execute_goal` signatures unchanged. `resume_goal` is an **additive** method on the agent adapter + (default/optional so `CLIRuntimeAdapter`/Gemini/Claude are untouched). +- **Collaborators via injection,** not new framework: `search_provider` joins `openrouter_client` as a + constructor-injected port (Rule 2) — the same pattern the registry already uses. +- **Registry untouched:** `@runtime_registry.register("hermes")` unchanged; routing + (`orchestrator.py:143,210-216`) unchanged except the P1 `terminate()` invocation. +- **Single execution chokepoint preserved:** commands keep routing through `SandboxManager`; files keep + routing through the S-4 confinement seam (Rule 9, no reach-around). + +### Q8 — How `AgentStepRecord` compatibility is preserved +- The **same fields** continue to be written every step: `execution_id`, `step_index`, `thought`, + `tool_name`, `tool_arguments`, `tool_result`, `status`, `last_heartbeat` (`hermes.py:262-273`). + Structured tool-calls populate `tool_name`/`tool_arguments` from the validated `ToolCall`; honest + results populate `tool_result` from `ToolResult.output`/`error`. **No column added or removed.** +- The only *value-level* change: failed steps write a non-`COMPLETED` `ExecutionStatus` value (already in + the enum) instead of always `COMPLETED.value`. This is the **resume system-of-record** + (`H-1-hermes-recovery-design.md` §2) and stays read-compatible with existing tests/consumers. + +### Q9 — How no schema redesign is achieved +- All H-2 (P0) changes are **logic-only**: branch removal, a structured-call validator, a search port, a + plan-generation call, and a real exit-status computation. No tables, columns, or migrations. +- Designed-through P1/P2 items that *could* imply persistence are constrained to **additive enum values** + (e.g. a TIMED_OUT/CANCELLED status, a cancel flag) **decided at the implementation AP** — additive, not + a redesign. Resume is a **read** over existing `agent_steps`/`workflow_checkpoints`. `confinement.py` + already exists (S-4). Net: **zero migrations** for H-2; additive-only enums if/when P1 lands. + +### Q10 — What qualifies Hermes as Experimental after H-2 +Per `ADR-hermes-v1.1-foundation` Prototype→Experimental gate, **all** must hold with tests: +1. **No simulation in the prod path** — `AsyncMock`/`is_mocked` removed (P0-1). +2. **Real exit status** — outcome-derived `exit_code`/status; failures finalize FAILURE (P0-4). +3. **Real search** — `SearchProvider` with a real provider; canned = test double (P0-5). +4. **Structured tool-calls** — schema-validated; malformed = explicit error, not silent `finish` (P0-2). +5. **Goal-derived plan** — generated from the goal, advisory, no literal (P0-3). +6. **Real-LLM-branch tests** — coverage of the real decision path, real search, honest failure (P0-6). +AP-105 ledger Caps 2, 3, 4, 8, 18 reclassify ≥ Partially-Implemented with tests. **Lifecycle safety +(terminate/resume) is NOT required for Experimental** — that is the Pilot bar (H-4). + +## 4.

In scope (H-4) + +| ID | Item | Tier | +|---|---|---| +| P1-1 | Functional `terminate()` (cooperative cancel + in-flight sandbox kill) | Pilot | +| P1-2 | Cooperative cancellation: DB-observable signal, loop-boundary checks, **orchestrator wiring** | Pilot | +| P1-3 | `resume_goal(execution_id)` — read-reconstruct trajectory + plan, continue, fail-closed | Pilot | +| P1-4 | Fail-fast initialization (raise on missing usable key) | Pilot | +| P1-5 | Configurable execution budget (additive config; default preserved) | Pilot | +| P1-6 | Timeout lifecycle: enforce ADR-010 wall-clock + budget → `TIMED_OUT` terminal | Pilot | +| P1-7 | One audited real governed run producing genuine output | Pilot (evidence) | + +## 3.
