From b9613a46e097612802b417cf15c967f433c8ece5 Mon Sep 17 00:00:00 2001 From: "Mars.P" Date: Tue, 6 Oct 2026 16:38:40 +0800 Subject: [PATCH] Pin which repository surfaces Claude runs still load The settings pin (--setting-sources user, with the workspace added back as an --add-dir) was documented as loading .claude/rules and as leaving a subdirectory's CLAUDE.md no route. Against Claude 2.1.263 only rules without a paths: frontmatter load from an added directory, and an --add-dir naming a subdirectory does load its memory in place. The sealed-egress note also claimed the runner writes no settings.json, which is false for an acceptance-bearing run's Stop hook; the CLI layers --settings over that file, so the hook still runs. A non-root arm now pins that: an acceptance-bearing Allowlist run's own Stop hook must leave its marker, with --settings on the argv. The E2E only checked that each repository's CLAUDE.md reached the model, so nothing would catch a CLI release that starts loading what the pin drops or stops loading what it keeps. Each Claude arm now plants both sides. .claude/CLAUDE.md, an unscoped rule and an in-repository @import must be in the first request. A skill, a command, an agent, CLAUDE.local.md, a paths:-scoped rule, sub/CLAUDE.md and a repository output style must reach no request, run none of their commands and stay off the init line, after the scripted model has read sub/notes.txt, invoked the skill and the command and delegated to the agent. The scoped rule and sub/CLAUDE.md attach only once that Read happens, so each repository's sub/notes.txt must come back to the model as a tool result. The scripted model gains named Claude tool calls, and refuses with a 400 any call the request does not offer, so a renamed tool fails the run at once. The Codex arm pins that a repository skill's openai.yaml MCP dependency is never started. Dropping --setting-sources (with the hijacking env left out so the run still reaches its broker) fails every drop assertion in the single-repo arms, and in the multi-repo arm the skill, command, agent, CLAUDE.local.md, scoped-rule and sub/CLAUDE.md ones: 2.1.263 reads no settings from a repository below a multi-repo cwd, so that arm's settings checks guard a later CLI. Dropping the add-dir memory switch fails every kept one. --- .github/workflows/sandbox-isolation.yml | 4 +- .../Harnesses/Claude/ClaudeCodeHarness.cs | 33 +- .../NonRootWorkerE2ETests.cs | 14 +- .../RepositoryConfigE2ETests.cs | 357 ++++++++++++++++-- .../ReviewerReadsItsDiffE2ETests.cs | 6 +- .../ScriptedModelUpstream.cs | 56 ++- .../Workflows/ClaudeCodeHarnessTests.cs | 5 +- 7 files changed, 413 insertions(+), 62 deletions(-) diff --git a/.github/workflows/sandbox-isolation.yml b/.github/workflows/sandbox-isolation.yml index 02b10a420..0fb7cbf5e 100644 --- a/.github/workflows/sandbox-isolation.yml +++ b/.github/workflows/sandbox-isolation.yml @@ -411,9 +411,9 @@ jobs: root = ET.parse(path).getroot() counters = root.find('.//{*}Counters') executed, passed = int(counters.get('executed')), int(counters.get('passed')) - assert executed >= 16 and passed == executed, f'expected all 16 non-root arms to run and pass, got executed={executed} passed={passed}' + assert executed >= 17 and passed == executed, f'expected all 17 non-root arms to run and pass, got executed={executed} passed={passed}' text = open(path, encoding='utf-8').read() - for marker in ('[non-root-e2e] ran admission uid=1654', '[sealed-egress-e2e] ran non-root durable uid=1654', '[sealed-egress-e2e] ran non-root non-durable uid=1654', '[sealed-egress-e2e] ran non-root restart uid=1654', '[sealed-egress-e2e] ran non-root relay-refused uid=1654', '[sealed-egress-e2e] ran non-root relay-ipv6', '[broker-socket-e2e] ran non-root socket-channel uid=1654', '[review-diff-e2e] ran non-root network-off-relayed claude-code uid=1654', '[review-diff-e2e] ran non-root network-off-relayed codex-cli uid=1654', '[durable-egress-e2e] ran non-root allowlist-severed uid=1654', '[repo-config-e2e] ran non-root claude-code single-repo Standard uid=1654', '[goal-channel-e2e] ran non-root mentions claude-code Standard uid=1654 confined=True', '[goal-channel-e2e] ran non-root resume claude-code Standard uid=1654 confined=True', '[goal-channel-e2e] ran non-root slash /fix claude-code Standard uid=1654 confined=True', '[goal-channel-e2e] ran non-root slash /security-review claude-code Standard uid=1654 confined=True', '[publish-isolation-e2e] ran non-root claude-code uid=1654 confined=True'): + for marker in ('[non-root-e2e] ran admission uid=1654', '[sealed-egress-e2e] ran non-root durable uid=1654', '[sealed-egress-e2e] ran non-root non-durable uid=1654', '[sealed-egress-e2e] ran non-root restart uid=1654', '[sealed-egress-e2e] ran non-root relay-refused uid=1654', '[sealed-egress-e2e] ran non-root relay-ipv6', '[broker-socket-e2e] ran non-root socket-channel uid=1654', '[review-diff-e2e] ran non-root network-off-relayed claude-code uid=1654', '[review-diff-e2e] ran non-root network-off-relayed codex-cli uid=1654', '[durable-egress-e2e] ran non-root allowlist-severed uid=1654', '[repo-config-e2e] ran non-root claude-code single-repo Standard uid=1654', '[repo-config-e2e] ran non-root claude-code own-stop-hook sealed-egress Standard uid=1654 confined=True', '[goal-channel-e2e] ran non-root mentions claude-code Standard uid=1654 confined=True', '[goal-channel-e2e] ran non-root resume claude-code Standard uid=1654 confined=True', '[goal-channel-e2e] ran non-root slash /fix claude-code Standard uid=1654 confined=True', '[goal-channel-e2e] ran non-root slash /security-review claude-code Standard uid=1654 confined=True', '[publish-isolation-e2e] ran non-root claude-code uid=1654 confined=True'): assert marker in text, f'non-root arm marker "{marker}" is missing — the arm returned early or did not run as the worker uid' print(f'All {executed} non-root arms ran as uid 1654 and passed.')
