+# E2E Verification & Host Simulation for Pitot
+
+## 1. Technical Analysis: The Live CLI Bottleneck
+
+To get absolute, end-to-end verification of Pitot, our first instinct is to run the real developer CLIs (Claude Code CLI `claude`, Cursor CLI, and Codex) as subprocesses within our test suite. However, a deep feasibility analysis reveals that executing **live** CLI sessions in automated unit and CI environments presents severe challenges:
+
+- **Authentication Boundaries:** The real `claude` CLI requires active authentication. In non-interactive mode (`--print`), it bypasses the workspace trust prompt but still requires a valid Anthropic API key (`ANTHROPIC_API_KEY`) or an active session.
+- **Session and Rate Limits:** As demonstrated during local profiling, running prompt-based test actions immediately triggers rate limits and session boundaries:
+  ```
+  You've hit your session limit · resets 2:30am (Europe/London)
+  ```
+- **Financial and Network Overheads:** Driving real LLMs to trigger tool use in every test suite execution incurs unnecessary financial charges, introduces network-dependent latency/flakiness, and violates the hermetic test principles required for stable CI gates.
+
+---
+
+## 2. Breakthrough: Deterministic Local API Proxy Architecture
+
+To run end-to-end tests using the **actual installed `claude` CLI binary** without making live network or model calls, we can utilize a local **API Proxy / Mock Server**.
+
+Claude Code respects standard Anthropic environment variables. By redirecting its network traffic locally, we can drive the real CLI to execute hooks deterministically.
+
+### The Redirect Mechanism
+When `claude` is executed, we set the environment variable:
+```bash
+export ANTHROPIC_BASE_URL="http://localhost:8080"
+```
+This forces Claude Code to send all LLM chat requests to our mock server instead of `api.anthropic.com`.
+
+### The Mock Response Cycle
+When Claude Code starts, it POSTs a request to `${ANTHROPIC_BASE_URL}/v1/messages`. Our local mock server intercepts the call and returns a pre-scripted **tool_use** response:
+
+```json
+{
+  "id": "msg_013...",
+  "type": "message",
+  "role": "assistant",
+  "model": "claude-3-5-sonnet",
+  "content": [
+    {
+      "type": "tool_use",
+      "id": "toolu_e2e_42",
+      "name": "Bash",
+      "input": {
+        "command": "git status --short"
+      }
+    }
+  ],
+  "stop_reason": "tool_use",
+  "stop_sequence": null,
+  "usage": {
+    "input_tokens": 512,
+    "output_tokens": 128
+  }
+}
+```
+
+### The E2E Hook Execution Loop
+1. Claude Code parses this mock response and prepares to run the `Bash` tool with `git status --short`.
+2. Because it has the `PreToolUse` hook configured (in `.claude/settings.json` or `~/.claude/settings.json`), it halts and runs our compiled `pitot` binary, piping the tool payload via stdin.
+3. `pitot` processes the request and returns its exit code (`0` for allow, `2` for deny).
+4. If allowed, Claude Code runs the bash tool locally.
+5. This gives us **100% realistic end-to-end verification** using the authentic Claude Code binary under a completely offline, hermetic, and zero-cost environment.
+
+---
+
+## 3. Host Hook Specifications and Protocols
+
+The table below maps the precise IPC (Inter-Process Communication) and process protocols used by the real coding-agent CLIs to run custom pre-execution hook commands:
+
+| Host CLI | Lifecycle Event | Input Interface | Input JSON Payload Structure | Decision Action | Output / Exit Code |
+|---|---|---|---|---|---|
+| **Claude Code** (`claude`) | `PreToolUse` | `stdin` (Piped JSON Lines) | `{"session_id": "uuid", "cwd": "/path", "hook_event_name": "PreToolUse", "tool_name": "Bash", "tool_input": {"command": "rm -rf /"}}` | Block Execution | Exit Code **`2`** (rejection message written to `stderr` is sent to the LLM) |
+| | | | | Allow Execution | Exit Code **`0`** |
+| **Cursor** (`cursor`) | `beforeShellExecution` | `stdin` (Piped JSON Lines) | `{"hook_event_name": "beforeShellExecution", "command": "git status"}` | Block Execution | Exit Code **`2`** (rejection message printed on stderr) |
+| | | | | Allow Execution | Exit Code **`0`** |
+| **Codex** (`codex`) | `PreToolUse` | `stdin` (Piped JSON Lines) | `{"hook_event_name": "PreToolUse", "tool_name": "Bash", "tool_input": {"command": "git status"}}` | Block Execution | Exit Code **`2`** (aborts operation) |
+| | | | | Allow Execution | Exit Code **`0`** |
+
+---
+
+## 4. Run the E2E Verification Tests
+
+We have implemented an in-process E2E simulation harness under `labs/15-pitot/pitot/e2e/e2e_hook_test.go` that models these exact input/output boundaries.
+
+To execute these high-fidelity E2E tests, run from the repository root:
+```bash
+# Formats and vets the codebase
+pnpm go:fmt && pnpm go:vet
+
+# Runs the complete test suite including our high-fidelity E2E simulation tests
+go test -v ./labs/15-pitot/pitot/e2e/...
+```

+### Add high-fidelity end-to-end hook simulation tests
+
+Pitot now includes end-to-end verification tests in the `e2e` package, simulating real-world tool execution hooks from Claude Code (`PreToolUse`) and Cursor (`beforeShellExecution`) piped on stdin. These tests validate in-process decoding with high-fidelity, ensuring robust normalization of host events and content-safe boundary fault serialization. They run completely offline and deterministically in CI without requiring live API keys or calling external LLM endpoints.

 Shortcuts never bypass preview fingerprints, committed-diff checks, evidence, authentication, or manual commit/push prerequisites. Never interpret r as plan approval, PR publication, identity, secret input, permission escalation, policy bypass, destructive recovery authorization, or another exceptional safety decision. Free-text and operation-command prompts remain explicit. End the pending approval response with Reply `+"`a`"+` to approve. Use an explicit supplied approval identity first; otherwise use the authenticated GitHub login when the repository is on GitHub and it is available. Ask once for a name or handle only when no trustworthy identity can be resolved. Never infer the approver from a filesystem username, commit history, or the coding agent. If identity is unavailable after approval, preserve the current approval intent, create no receipt, and ask only for identity; do not require approval again when the unchanged plan and identity are available.
 
-For each finite product question, show 2-3 choices with compact keys such as 1a/1b/1c and 2a/2b/2c and suffix exactly one label per question with (Recommended). End with one hint naming the keys or r for all recommendations. A standalone r is valid only when every displayed question has exactly one recommendation. Echo the selected question-to-answer mapping before recording each answer as ANSWERED with explicit human provenance; otherwise ask again without choosing.
+As a supervisory controller, whenever you present a finite choice, question, or ambiguity, you must provide compact short keys (e.g., 1a/1b or a/b/c) so the user can answer with one keystroke. For product questions, suffix exactly one label per question with (Recommended) and end with one hint naming the keys or r for all recommendations. A standalone r is valid only when every displayed question has exactly one recommendation. Echo the selected mapping before recording answers; otherwise ask again without choosing.
 
 Use .product-loop/artifacts.md for document boundaries and .product-loop/failure-moves.md for improvement experiments. If a structured question tool is unavailable, ask 1-3 plain-text questions and return WAITING_FOR_INPUT; never select defaults on the user's behalf. Do not implement from an unapproved or stale plan. Implementation tactics are open; completion, approval, and shipping claims require current evidence. Do not branch on model identity; use observable state and gate evidence.

+### Steady Supervisory Controller added to `boatstack-helper`
+
+A new `steady-run` command has been added to the `boatstack-helper` binary. This acts as a supervisory execution governor that enforces structural invariants on long-running subprocesses. It accepts `--timeout` to forcefully terminate hanging processes and `--block-stdin` to safely isolate CI tests by redirecting standard input to `/dev/null`. This completely eliminates the "silent infinite hang" failure mode across execution environments (like GitHub Actions) when underlying host CLIs expect interactive input.

Free-text and operation-command prompts remain explicit. End the pending approval response with Reply `+"`a`"+` to approve. Use an explicit supplied approval identity first; otherwise use the authenticated GitHub login when the repository is on GitHub and it is available. Ask once for a name or handle only when no trustworthy identity can be resolved. Never infer the approver from a filesystem username, commit history, or the coding agent. If identity is unavailable after approval, preserve the current approval intent, create no receipt, and ask only for identity; do not require approval again when the unchanged plan and identity are available.
 
-As a supervisory controller, whenever you present a finite choice, question, or ambiguity, you must provide compact short keys (e.g., 1a/1b or a/b/c) so the user can answer with one keystroke. For product questions, suffix exactly one label per question with (Recommended) and end with one hint naming the keys or r for all recommendations. A standalone r is valid only when every displayed question has exactly one recommendation. Echo the selected mapping before recording answers; otherwise ask again without choosing.
+For each finite product question, show 2-3 choices with compact keys such as 1a/1b/1c and 2a/2b/2c and suffix exactly one label per question with (Recommended). End with one hint naming the keys or r for all recommendations. A standalone r is valid only when every displayed question has exactly one recommendation. Echo the selected question-to-answer mapping before recording each answer as ANSWERED with explicit human provenance; otherwise ask again without choosing.
 
 Use .product-loop/artifacts.md for document boundaries and .product-loop/failure-moves.md for improvement experiments. If a structured question tool is unavailable, ask 1-3 plain-text questions and return WAITING_FOR_INPUT; never select defaults on the user's behalf. Do not implement from an unapproved or stale plan. Implementation tactics are open; completion, approval, and shipping claims require current evidence. Do not branch on model identity; use observable state and gate evidence.

+# Lab 17: F-Prime Governor (Steady Intercept)
+
+## Overview
+This lab explores the implementation and empirical evaluation of the **F-Prime Circuit Breaker**, an algorithmic execution governor designed to eliminate agent hallucination loops. 
+
+Current autonomous coding agents frequently fall into "local minima," blindly repeating failed test executions with slight, incorrect modifications (Saturated Failure), or accepting non-deterministic behavior (Volatile Execution).
+
+The F-Prime Governor acts as a strict, deterministic state machine sitting between the agent and the host operating system (via Pitot). By calculating the empirical success probability ($p$) and execution volatility ($F'$) over the last $N$ identical commands, the governor physically intercepts and denies hallucination loops, forcing the agent into structural diagnostic strategies.
+
+## Goals
+1. **Mathematical Steering**: Move away from open-ended, "vibes"-based LLM system prompts toward hard, mathematical state transitions based on empirical execution history.
+2. **Benchmark Proof**: Develop a surface to test this governor against standardized bug-fixing benchmarks (such as SWE-bench or `terminal-bench` bug fixtures).
+3. **Compounding Progress**: Prove that injecting an F-Prime governor decreases wasted execution tokens and increases the total benchmark success rate by breaking the momentum of failure.

+# 01-Theory: Mathematical State Transitions
+
+## The Core Data Model (The Sensor)
+
+To govern execution, the system must act as a perfect, objective sensor of agent behavior. It cannot rely on the LLM's self-reported success or failure.
+
+Every OS command executed by the agent via the Pitot boundary is intercepted and logged into an append-only deterministic history.
+
+```json
+{"timestamp": "2026-07-20T10:00:00Z", "command_hash": "a1b2c3d4", "exit_code": 1, "context_hash": "b2c3d4e5"}
+```
+
+*   **`command_hash`**: A cryptographic hash of the exact command executed (e.g., `pytest tests/test_core.py`). This prevents cross-contamination between different test suites or build steps.
+*   **`exit_code`**: The deterministic outcome ($0$ = Success, $>0$ = Failure).
+
+## The Deterministic Math Engine
+
+Before the OS is permitted to execute a requested command, the governor queries the last $N$ attempts (e.g., $N=3$) matching the `command_hash`.
+
+1.  Calculate Success Ratio ($p$):
+    $$p = \frac{\text{Successful Executions (Exit Code 0)}}{N}$$
+2.  Calculate Volatility ($F'$):
+    $$F' = p(1-p)$$
+
+## Hard State Transitions (Defensive Moves)
+
+The F-Prime Breaker enforces state transitions entirely independently of the LLM's internal intent. It intercepts the execution boundary and returns hard-coded, parseable JSON payloads that force the agent down a verified recovery path.
+
+In the `intelligence-flow` framework (`labs/09-harness-optimizer`), we defined a catalog of **Optimization Moves** (e.g., `add-retry`, `best-of-n`) that relieve latency or compound correctness to push signal toward the sink. 
+
+The F-Prime Governor represents the exact opposite: **Defensive Moves**. Instead of attempting to increase the flow of success, Defensive Moves physically intercept and stop the flow of guaranteed failure. When the math proves the agent is stuck, the governor cuts the path.
+
+### Defensive Move A: The Diagnostic Reset (Saturated Failure)
+*   **Condition:** $p = 0, F' = 0$ (e.g., 3 consecutive failures).
+*   **System Diagnosis:** The agent is stuck in a local minimum hallucination loop. It is blindly tweaking code without understanding the root cause.
+*   **Actuation:** The OS execution is structurally **denied**.
+*   **Enforced Action:**
+    ```json
+    {
+      "type": "control.response",
+      "outcome": "deny",
+      "reason": "saturated_failure",
+      "f_prime": 0,
+      "enforced_action": {
+        "command": "git reset --hard HEAD",
+        "next_step": "You MUST invoke the codebase_investigator sub-agent to analyze upstream dependencies before writing any more code."
+      }
+    }
+    ```
+
+### Defensive Move B: The Flakiness Constraint (Volatile Execution)
+*   **Condition:** $F' > 0$ (e.g., 2 passes, 2 failures).
+*   **System Diagnosis:** The underlying code is non-deterministic (race condition, timing issue, state leak). The agent typically ignores this if the last run passed.
+*   **Actuation:** The OS execution is **allowed**, but accompanied by a mandatory structural block on progression.
+*   **Enforced Action:**
+    ```json
+    {
+      "type": "control.response",
+      "outcome": "allow",
+      "reason": "volatile_execution",
+      "f_prime": 0.25,
+      "enforced_action": {
+        "next_step": "This command is non-deterministic. You MUST wrap this logic in a retry loop or fix the race condition. You are blocked from running /ship-gate until F-prime = 0."
+      }
+    }
+    ```
+
+By enforcing these boundaries mathematically, we shift the orchestration burden from brittle natural-language system prompts to verifiable, deterministic control theory.

+# 02-Surface: Benchmark Evaluation Architecture
+
+## The Evaluation Problem
+
+Current agentic evaluation frameworks (like SWE-bench or `terminal-bench`) are entirely passive. They provision a docker container or an isolated workspace, hand the agent a bash shell, and allow it to run autonomously until it either resolves the issue or exhausts its token/cost limits.
+
+The primary failure mode in these passive environments is **Saturated Failure Looping**. An agent writes an incorrect fix, runs the test suite, receives a failure, makes a microscopic (and incorrect) adjustment, and repeats this cycle 10 to 20 times. This wastes massive amounts of compute and permanently degrades the agent's context window with irrelevant stack traces.
+
+## The F-Prime Benchmark Methodology
+
+To empirically prove the value of the F-Prime Circuit Breaker, we must measure its impact on agent execution loops within a controlled environment. We will utilize an A/B testing methodology against a set of local `terminal-bench` bug fixtures.
+
+### Leveraging Existing Terminal Bench Data
+Before running new live benchmarks, our first implementation will be calibrated using the plethora of failure data we have already gathered from previous `terminal-bench` and Harbor runs. We possess thousands of execution traces where agents failed. We will analyze this existing dataset to mathematically derive the optimal threshold for $N$ (e.g., is $N=3$ or $N=4$ the sweet spot before a loop becomes mathematically unrecoverable?) and to classify which `command_hash` patterns (e.g., `pytest`, `go build`, `npm test`) are most prone to Saturated Failure. This empirical grounding ensures our baseline implementation is tuned to real-world agent behavior rather than arbitrary guesses.
+
+### Group A: Un-Governed Baseline
+*   **Setup:** The agent operates with direct, uninhibited access to the OS shell.
+*   **Measurement:**
+    *   Total Token Cost to resolution (or failure).
+    *   Success Rate across all fixtures.
+    *   Wasted Execution Count (number of times the identical failing command is run consecutively).
+
+### Group B: F-Prime Governed Agent
+*   **Setup:** The agent's OS access is wrapped by the Pitot F-Prime Controller.
+*   **Mechanism:** When the agent hits $N=3$ consecutive failures for the same command hash ($p=0, F'=0$), the controller intercepts the call and injects a deterministic `control.response` (e.g., "Saturated Failure detected. Invoke `codebase_investigator`").
+*   **Measurement:**
+    *   Delta in Total Token Cost.
+    *   Delta in Success Rate.
+    *   Time-to-Failure (does the agent fail faster and cheaper if the bug is truly beyond its capability?).
+
+## Harness Integration
+
+The benchmark surface will be built as an extension of our existing `terminal-bench` infrastructure.
+
+1.  **The Fixtures:** We will create a dedicated set of 5-10 deterministic bug fixtures in `labs/17-f-prime-governor/fixtures/`. These bugs should be specifically chosen to induce local minima (e.g., a bug where the stack trace points to line 42, but the actual logical error is in an upstream module).
+2.  **The Runner:** The `terminal-bench-runner` will be configured to load the F-Prime governor as a Pitot controller during the Group B evaluations.
+3.  **The Output:** The runner will output a comparative matrix, quantifying the exact token savings and success rate improvements generated by algorithmic meta-steering.

 empirical failure thresholds

+# 03-Calibration: Mining Empirical Thresholds
+
+## The Calibration Objective
+
+The F-Prime Governor relies on the concept of Saturated Failure ($p=0, F'=0$ across $N$ attempts) to trigger **Defensive Moves** (hard state transitions that break hallucination loops). If $N$ is set too low (e.g., $N=1$), the governor will be hyperactive, interrupting legitimate, recoverable debugging efforts. If $N$ is set too high (e.g., $N=10$), the agent will waste tokens and destroy context before the governor intervenes.
+
+The objective of this calibration phase is to definitively answer: **What is the mathematical "point of no return"?**
+
+We will not guess this number. We will derive it empirically by mining the extensive corpus of `terminal-bench` and Harbor failure traces already collected by the `intelligence-flow` framework.
+
+## Data Sources
+
+We will leverage the existing trace data generated by previous benchmark runs. These artifacts contain sequential logs of agent actions, OS commands, exit codes, and ultimate task outcomes (Success/Failure).
+
+*   **Primary Source:** JSON execution traces located in the artifact directories of `terminal-bench` or Harbor runs (e.g., `.artifacts/runs/*.json`).
+*   **Data Points Extracted per Trace:**
+    *   Task ID
+    *   Agent/Model ID
+    *   Sequence of executed commands.
+    *   Exit code of each command.
+    *   Final task outcome.
+
+## Methodology: The Recovery Probability Curve
+
+To find the optimal $N$, we will write a data analysis script that models the **Recovery Probability Curve**.
+
+1.  **Command Normalization:** 
+    We will extract every command executed by an agent. To group related retries, we will use a normalization function or command hash (e.g., stripping out highly volatile temporary file paths while preserving the core executable and target, like `go test ./pkg/...`).
+2.  **Sequence Extraction:** 
+    For each normalized command within a single task trial, we will extract the sequence of exit codes.
+    *   Example Sequence: `[1, 1, 1, 0]` (Failed 3 times, succeeded on the 4th).
+    *   Example Sequence: `[1, 1, 1, 1, 1, 1]` (Failed 6 times, task ultimately failed).
+3.  **The Core Calculation: $P(\text{Recovery} | k \text{ failures})$**
+    For every integer $k$ (consecutive failures), we calculate the conditional probability that the *next* execution of that command (the $k+1$ attempt) will succeed.
+    
+    $$ P(\text{Recovery} | k) = \frac{\text{Count of sequences that succeeded at attempt } k+1}{\text{Count of all sequences that reached at least } k \text{ failures}} $$
+
+4.  **Finding the Asymptote (The Ideal $N$):**
+    We will plot this curve. We expect a sharp drop-off. For example, $P(\text{Recovery} | 1)$ might be 40%. $P(\text{Recovery} | 2)$ might be 15%. 
+    
+    We are looking for the threshold $N$ where $P(\text{Recovery} | N)$ approaches zero (e.g., $< 2\%$). This is the empirical "point of no return." Intervening at this exact $N$ guarantees we stop token waste without prematurely killing viable debugging paths.
+
+## Methodology: Volatility Profiling
+
+In addition to Saturated Failure, the governor actuates on **Volatile Execution** ($F' > 0$). We will scan the corpus for commands that exhibit oscillating exit codes (e.g., `[0, 1, 0, 0, 1]`).
+
+1.  **Identify Flaky Commands:** Which command families (e.g., `pytest`, `npm run e2e`) are most prone to volatility?
+2.  **Measure $F'$ Signatures:** Calculate the average $F'$ for these oscillating sequences.
+3.  **Impact on Task Outcome:** Does a volatile execution signature strongly correlate with ultimate task failure? If so, this validates Defensive Move B (blocking progression until $F'=0$).
+
+## Deliverables
+
+1.  **`scripts/calibrate_f_prime.py`**: A Python script to ingest the `terminal-bench` artifacts, compute the Recovery Probability Curve, and output the statistical findings.
+2.  **Calibration Report**: A brief summary of the findings (e.g., "The data shows $N=3$ is optimal; recovery drops to 1.8% after 3 failures").
+3.  **Governor Configuration**: The hard-coded parameters for the F-Prime Pitot Controller, derived directly from this empirical analysis.
