• Add E2B through its maintained adapter, using an organization template and encrypted API key in the existing sandbox configuration and agent assignment flows.
• Page sandbox_read_file through the public workspace backend with line offsets, up to 2,000 lines per page, and the existing 40,000-character limit.
• Keep sandbox leases, command behavior, and durable artifact downloads while covering credential isolation, paging, truncation, and cancellation.

Rebased onto main f200d41f9055e8967102da2d8f9b4b5c5e529a72. Application and test changes are preserved. The two documentation conflicts retain main's lifecycle guidance plus E2B and paging details.

• Setup, migration, seeding, and SDK build passed.
• Focused sandbox tests, Platform build, hosted checks/reviews, and both browser suites are running for this head.
• The Platform browser suite uses a command-line 600-second test budget, matching the journey's existing budget and avoiding the previously diagnosed 30-second multi-step usage-limit timeout. No test code changed.

This follow-up replaces the custom sandbox path normalization loop with node:path.posix.resolve, preserves virtual workspace mapping and containment checks, and pins experimental @tanstack/ai-harness to 0.1.0. It removes 12 net lines. Compaction is outside this change.

Check	Result
Hosted checks	All 11 currently reported checks passed for this head
Focused sandbox tests	17 passed across path resolution and sandbox tool tests
Formatting and type-aware lint	Passed
Frozen-lockfile install	Passed, with no dependency version changes
Platform and SDK builds	Passed
Binary smoke	Passed with a disposable database, removed afterward
Todos deterministic browser suite	66 passed in 5.0m
Platform browser suite	13 passed, 1 usage-limit flow exceeded its 30-second test timeout in a 7.1m run
Focused Platform rerun	4 passed in 4.4m, including preflight, the dashboard journey, and the usage-limit flow, with a command-line 180-second timeout

The original usage-limit trace contained only a test timeout. Every step completed, and the final page showed the expected deletion confirmation and remaining rows. The focused rerun changed only the command-line timeout. No usage-limit source or test code changed. The original report and trace were preserved outside the worktree before the rerun.

Current local reports: platform/e2e/.output/report/index.html (focused rerun) and examples/todos/e2e/.output/report/index.html (66-test suite). Original Platform suite evidence: /tmp/astralbeam-harness-evaluation-J91hcF/platform-browser-first-run/report/index.html.

Live E2B remains unverified without an organization API key. The earlier live paging/download check was blocked before sandbox execution by the seeded OpenAI connection's invalid_api_key. Neither external check is counted as passing.

The new commit is unsigned because signing was unavailable in this session. Signing configuration was not changed.

Check	Result
Hosted checks	All 12 passed, including Platform unit/integration tests, builds, and security reviewer
Platform browser suite	14 passed in 6.5m
Todos deterministic browser suite	66 passed in 5.0m
E2B form browser check	2 passed, including sign-in setup, in 1.9m
Local Platform checks	Formatting, OpenAPI freshness, lint/types, and Knip passed
Local Platform tests	680 passed, 2 skipped, 2 email-delivery test timeouts; all 6 email-delivery tests passed on an isolated rerun without code changes
Builds	Platform, SDK, and Todos passed
Todos checks/unit tests	Checks passed, 3 tests passed
Binary smoke	Passed with a disposable database before the test-only simplification; production code unchanged

Codex code and security reviews completed with no findings for this head.

The E2B form check verifies the base template default, a masked API key, and clearing credentials when switching providers. Paging, virtual workspace paths, empty files, long-line truncation, cancellation, credential isolation, and failed cleanup passed in local tests.

The live paging/download browser check was blocked before sandbox execution because the seeded OpenAI provider rejected its API key (invalid_api_key). Live E2B remains unverified without an organization API key. These external checks are not counted as passing.

Local browser reports: platform/e2e/.output/report/index.html and examples/todos/e2e/.output/report/index.html. The live paging failure report was retained separately outside the worktree.

Template defaults, masked API key, and credential clearing when switching providers. The recording uses disposable seeded data and a synthetic key.
