Build, provenance and integrity

This archive is built from current allowlisted source, same-runtime fixed data

and public documents. No historical release, preview or experiment is copied.

data/fixed-v0.2/ is generated by scripts/export_fixed_data.py from World

initialization; run it with --check to detect any field or file difference.

The data source files and each exported file carry SHA256 identities.

The start/ page and its saved reports are generated by scripts/build_first_use.py

using this code and fixed data. Samples are synthetic deterministic scripts,

not live model results. Each presentation copy omits only elapsed_seconds and

adds sample_metadata; original state, actions, output and scoring are preserved.

The builder saves unprojected source reports in source-runs/ beside the zip.

build-summary.json binds their hashes to the projected sample hashes by key.

Timing is not a benchmark measure here. Raw build reports are outside the archive

so the source archive can be byte-identically rebuilt.

MANIFEST.json lists every payload SHA256, length and generation/copy origin.

It excludes itself and MANIFEST.sha256 to avoid circular hashes. Check the

manifest sidecar and each payload; a digest establishes consistency, not trust

in an unknown publisher. README entry pages are curated for portability and the

license-scope copy replaces only repository-status prose, retaining license terms.

The checker uses a fresh no-pip virtual environment and clean extraction, without

workspace source or inherited PYTHONPATH. It blocks network attempts in runtime

subprocesses, checks both languages and tasks, expected refusal, data and links.

This is engineering verification, not hostile-code containment or real-model testing.

Build outputs must use a new directory. The optional --engineering-only mode

replaces unfinished public guides with explicit draft placeholders; it is never

a final user candidate and must not be used for acceptance.
