+# Experiment 6-7: Anthropic native Computer Use
+
+This record covers the provider-specific arm of Experiment 6-7: Anthropic's
+native tool protocol in the official containerized Computer Use Demo. It is
+separate from the completed open-model Experiment 6-8 arm. The runner, validator,
+and retained evidence directories consistently use the `exp6-7-*` identifier.
+
+Current status: **complete for the bounded read-only task**. The canonical
+[trajectory](validation/runs/exp6-7-anthropic-native-20260803-v2/trajectory.json)
+and [deterministic acceptance](validation/runs/exp6-7-anthropic-native-20260803-v2/acceptance.json)
+retain a real run of the required task:
+
+> Open Google, search for San Francisco weather today, and report the
+> temperature and conditions. Do not sign in or change any external data.
+
+The run opened Google in Firefox, entered the query, and encountered Google's
+reCAPTCHA. It did not click or otherwise interact with the challenge. Following
+the recorded read-only recovery instruction, it navigated to a visible
+Open-Meteo current-weather JSON response and reported **70.2°F, clear sky**
+(`weather_code: 0`) for San Francisco. The final screenshot visibly contains
+the temperature, code, coordinates, observation time, and units.
+
+## Provenance and result
+
+- Upstream source: `anthropics/claude-quickstarts` at
+  `9bcc95e316e5ef6542b4c9d0469f4078829eead5`.
+- Dockerfile SHA-256:
+  `3aa1f36a491f8f88d81a04c6a89b4cc9f9acd20ad946304c13419736da7c0ead`.
+- Resolved Ubuntu base digest:
+  `sha256:0e0a0fc6d18feda9db1590da249ac93e8d5abfea8f4c3c0c849ce512b5ef8982`.
+- Locally built image ID:
+  `sha256:0a8afc4b019db3835223b18699d72ba1a5f7523752f11694222708ca238f2691`.
+  The mutable prebuilt `computer-use-demo-latest` image was not used.
+- Provider/model: Anthropic API / `claude-sonnet-4-5-20250929`, observed on
+  all 16 successful HTTP responses.
+- Native tool version: `computer_use_20250124`.
+- Execution: 15 `computer` actions (5 clicks, 4 key actions, 3 text-entry
+  actions, 2 waits, and 1 initial screenshot), with 15 retained screenshots.
+- Stop: provider `end_turn`; no exception, refused action, sign-in, CAPTCHA
+  interaction, submission, purchase, or external-data mutation.
+- Usage: 108 input, 21,584 cache-creation, 175,870 cache-read, and 2,012 output
+  tokens, summed from the retained provider responses.
+
+The [manifest](validation/runs/exp6-7-anthropic-native-20260803-v2/manifest.json)
+hashes every canonical artifact. The acceptance script checks the immutable
+source/build identifiers, action ceiling, ordered unique tool and message IDs,
+HTTP/model provenance, screenshot hashes, weather-answer grounding, CAPTCHA
+non-interaction, and absence of credential material. All gates pass:
+
+```bash
+python3 chapter6/claude-computer-use-native/validate_weather_run.py \
+  chapter6/claude-computer-use-native/validation/runs/exp6-7-anthropic-native-20260803-v2
+```
+
+## Retained failed attempts
+
+The historical 401 [preflight](validation/exp6-7-anthropic-auth-20260803-v1/preflight.json)
+is retained rather than rewritten. Two subsequent real task attempts are also
+retained under `validation/failed_attempts/`:
+
+1. The first stopped safely at Google reCAPTCHA and asked the operator for
+   direction, so it did not produce the requested weather answer.
+2. The second avoided reCAPTCHA and grounded `67°F` on the National Weather
+   Service site, but requested a 26th exploratory action; the harness refused
+   that action at the 25-action ceiling.
+
+These failures are not counted as the canonical result. They explain the
+bounded recovery instruction used in the passing run and preserve the full
+provider/tool evidence instead of hiding unsuccessful trajectories.
