Then checks each path it might have missed.
Chrome and helpers find their place,
The docs record each process trace.
A test keeps watch as sources grow,

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
The documentation match is loose and can hide an undocumented spawn.
The check passes if any single line contains the crate name and the file stem. Common stems such as mod, process, or focus can match unrelated text. For example, any line that mentions tinycomputer-accessibility and the word process passes. A new spawn in crates/tinycomputer-accessibility/src/other/process.rs would then count as documented. Match on the full relative path, or on the stem together with its parent directory.

A new spawn in a reused filename can bypass this guard: for example, crates/tinycomputer-accessibility/src/other/process.rs is accepted because the existing inventory line contains both tinycomputer-accessibility and process, even though that path and process were never documented. Compare the normalized relative path against structured inventory entries rather than matching only the crate and file stem.

There was a problem hiding this comment.
When SessionOptions::endpoint is set to an http://, ws://, or wss:// DevTools endpoint, crates/tinycomputer-browser/src/convert/session.rs forwards it as cdpUrl, causing the module to connect directly to that endpoint. This traffic is neither a model call nor traffic from a browser to a site, so the stated exhaustive egress list omits a supported outbound connection that a host needs to account for.

Adding the link only to the specifications index leaves the new document absent from both docs/README.md and the root "Read The Right Document First" table, so contributors looking for the repository's containment rules through the prescribed entry points will not find it. Add the required links in both places.

This file is placed under tinycomputer-core/tests, but it neither exercises that crate's public API nor follows the required *_tests.rs integration-test naming; instead it crawls unrelated workspace source and documentation. Move this repository-wide policy check into CI/tooling, rather than coupling cargo test -p tinycomputer-core to the checkout layout.

The document is marked Accepted while omitting the specification template's goals/non-goals, proposed behavior, invariants, acceptance criteria, and open questions, and this commit implements the inventory test without creating the required linked implementation plan. Complete those sections and add the plan so the decision and its verification remain auditable.

Part of tinyhumansai/openhuman#7328 (phase 5).
Assesses browser/helper process startup and egress. Result: no enforceable sandbox/proxy contract exists in the module (Chrome is spawned by agent-browser with no proxy forwarded; helpers need host desktop access), so none is added. Adds docs/technical/specs/process-containment.md listing every unsupported process explicitly, and a test that fails when a crate gains a process spawn not named in the doc. No release needed.
