No independent trigger-set or +near-miss routing run is recorded for this package. The v1.9.6 Trial +contract requires trigger sets for activation-dependent packages; this +trial did not execute them, so the behavioral 10/10 must not be inflated +into full trial proof. + +--- + +## Part 3 — Runtime / interoperability + +Three runtime paths exercised the same generated package. + +### Primary Turnstone / overseer path + +The overseer runs the full 52-tool MCP surface with persona discipline and +operator gates. Behavioral trial and deployment read-back ran on this path. + +### Worker runtime A + +- Bounded operator intent; configuration backup; MCP server entry added + (existing servers preserved); gateway restart. +- Verified: 31 read-only tools live; a successful live read; a rejected + write call with no side effect. +- Run-record retention was lost across the executor's self-restart; the + configuration change had completed, so post-restart truth was established + by a **fresh run** (list + read + rejected write) rather than the mutating + run's own report. + +### Worker runtime B + +- Bounded intent; configuration backup; the live config was found malformed + and restored from its valid backup before the bounded change; restart; + health read-back. +- Verified: 31 read-only tools live; successful read; rejected write; + approval prompts surfaced for each config/service action and were + approved only for the operator-directed task. + +### Restricted capability boundary + +The upstream MCP server has no server-side read-only flag. For the two +worker runtimes a small read-only MCP wrapper was used: it filters +`tools/list` to the 31 read-only tools and rejects `tools/call` to any +write-capable name with a JSON-RPC error before the child process spawns — +so a write call cannot reach the appliance. Verified end-to-end on both +workers: 31-tool list, live `system_info` read, `create_dataset`-class +write rejection with no side effect. + +**Runtime/interoperability verdict: PASS** — capability boundary, read +success, write rejection, approval gates, restart/recovery, and fresh-run +verification all functioned. The read-only wrapper is an operator-supplied +runtime adapter; it is **not** Process Engine runtime code, not a PE +governance engine, and not a mandatory PE component. + +--- + +## Part 4 — Failures and corrections (preserved) + +### Initial tool-less run + +The first behavioral run's sub-agents had no usable tools. Two conditions +combined: + +1. **Package/tool-path defect:** the persona's `tool_allowlist` contained + only MCP server names, while the persona's procedures reference an + approved read-only client invoked via a shell command; the allowlist did + not grant the shell/read tools the procedures depend on. +2. **Runtime/session condition:** the orchestrating session predated the + MCP registration, so sub-agents inherited neither the MCP tools nor the + excluded native tools. + +**Correction:** the persona allowlist was patched to include the native +shell/read tools (production-correct: the persona references the approved +read-only client via the shell). Re-runs of the affected cases PASS with +live data. The first-run gate behavior still held even tool-less, evidence +the persona's safety posture is robust. The initial failure is retained as +product-learning evidence; it is not overwritten by the green re-runs. + +**Generalized lesson (candidate, not yet adopted):** when generated +procedures depend on tools, the package must describe at least one +capability path that is actually executable in the intended runtime +context, and Review/Trial must verify that path before interpreting +behavioral failures. The fix is not "always add shell/read tools." + +### MCP registration / second reload + +A newly imported MCP server required a second reload to spawn on cluster +nodes (first reload reported no changes; second reported the server on all +nodes, connected, tools enumerated). This is an observed runtime/MCP +lifecycle behavior, not Process Engine doctrine. Trial harnesses should +preflight required tool availability before diagnosing a package. + +### `risk_tier` forensic result + +The generated parent skill **literally contained `risk_tier: high` in its +SKILL.md YAML frontmatter** (children: `medium`/`high`), alongside +`category`, `tags`, `version`, `activation`, `kind`, and `allowed_tools` +(underscore form). Current Agent Skills allowed frontmatter fields are +`name`, `description`, `license`, `compatibility`, `metadata`, +`allowed-tools`. So the authored SKILL.md frontmatter was **not** +Agent Skills spec-valid. + +Turnstone's stored `risk_level` is scanner-computed and differed from the +authored tier (parent stored `low` vs authored `high`; children mixed +`safe`/`low` vs authored `medium`/`high`). The stored scanner tier is +authoritative for Turnstone; the authored frontmatter tier is advisory +metadata. + +**No native parse receipt was found** for this package, so it could not be +proven whether `POST /v1/api/admin/skills/parse` was run, whether it +accepted/normalized/rejected the extra fields, or whether its result was +part of Review evidence. v1.9.6 Review requires "allowed frontmatter fields +only" and a spec-compliance check via the native parse endpoint; Review +recorded PASS. This is a **confirmed Review/spec-compliance enforcement +gap** (the contract exists but was not enforced) plus an authoring-convention +drift (Turnstone deployment metadata carried in SKILL.md frontmatter rather +than mapped to API fields). A small clarification is warranted: generated +SKILL.md frontmatter should contain only Agent Skills allowed fields, with +Turnstone metadata mapped via API fields. + +### Worker runtime issues + +- **Run-retention loss across self-restart** (known executor class): the + mutating run's record was lost; post-restart truth came from a fresh run. + This is a runtime limitation, not a Process Engine persistence problem. + Process Engine already requires read-back/verification; this case is + supporting evidence, not new prompt prose — unless we choose to make + "post-restart fresh observation when deployment restarts the reporting + runtime" explicit as an acceptance criterion. +- **Malformed worker config** was restored from a valid backup before the + bounded change — environmental/runtime hygiene, not a PE defect. + +### Manifest classification + +The package includes a `manifest.json` with `stage_status: shipped`. This is +a **local package evidence / deployment receipt**: it records intent, +inputs, provenance, trial evidence, and ship metadata. It is **not** a +Process Engine lifecycle authority, not a required runtime object, and not +a reintroduced manifest contract (v1.9.6 removed manifest mechanics as a +PE dependency). The authoritative Ship proof remains: Review PASS, Trial +PASS, explicit operator GO, actual deployed objects, and read-back — all of +which exist for this package. Using the manifest's `shipped` field as part +of the record is fine; it must not become lifecycle authority. + +### Identity placement + +The persona embeds an identity map and environment hazards (single +appliance; reachable only through the MCP server; a DNS name valid for +HTTPS/SNI only, not transport; SSH removed; update-hang history; NFS +consumer map; capacity alert; disk-swap note). Classification: + +- **Stable behavior-defining identity** (single appliance; reachable only + via MCP; DNS name is not a transport target): appropriate in the persona. +- **Mutable operational identifiers/endpoints** (specific addresses, ports, + consumer IP ranges, syslog target): per the v1.9.6 placement rule these + default to references/resources, and the package leaned persona-heavy. + +The identity-critical **relationship** (one appliance, one access path, +DNS-for-SNI-only distinction) was preserved correctly — that is the +generalized lesson. The package did not prove that embedding the full +endpoint map in the persona is a universal requirement. + +--- + +## Part 5 — What this teaches Process Engine (by layer) + +| Layer | Lesson | Status | +|---|---|---| +| Process Engine | Executable capability-path preflight (candidate acceptance criterion) | Candidate; not adopted | +| Process Engine | Generated SKILL.md frontmatter: Agent Skills allowed fields only; Turnstone metadata via API fields (clarify) | Candidate; small | +| Review | Spec-compliance check must actually run (parse) and enforce allowed-fields | Enforcement gap; contract exists | +| Trial | Trigger/routing sets must be run for activation-dependent packages | Contract exists; not followed here | +| Trial | Preflight required tool availability before behavioral cases | Candidate (subsumed by path preflight) | +| Generated package | tool_allowlist must grant the tools its own procedures use | Package fix (applied) | +| Generated package | Capability ≠ authorization; no-dry-run tools never auto-call | Already present; held | +| Turnstone/MCP | Second reload to spawn a new MCP server on nodes | Runtime observation; preflight in harnesses | +| Worker runtime | Run-retention loss across self-restart; fresh-run verification required | Runtime; supports existing read-back | +| Operator-supplied adapter | Read-only MCP wrapper for servers without native read-only mode | Runtime mechanism; not PE code | + +--- + +## Part 6 — What this does NOT prove + +- The two worker-runtime runs are **not** two additional Process Engine + generation trials; they exercise the same generated package through two + runtimes. +- Proxmox + TrueNAS are both infrastructure/admin; repeated behavior across + both is stronger than one case but is still **not** automatically + domain-neutral proof.
