docs(research): audit official app parity

Summary

• I recorded the essential-parity audit requested by #146; it found no deal-breaking disparity, so the validated native repackage remains the active ChatGPT producer.
• I bound the parity decisions to retrieved source digests, immutable repository revisions, the SHA-256-pinned OpenAI package, and its extracted Electron version evidence.
• I aligned the context and package-runtime guidance on one steady-state policy: pacman and the signed CachyOS repository perform routine upgrades without the retired transition-only IgnorePkg hold.

Changes

• The audit distinguishes essential parity, accepted operational warnings, discretionary port integrations, and explicit reopen conditions.
• Host and audit evidence is dated August 17, 2026; external sources were retrieved again on August 18 with recorded digests and immutable revisions where available.
• Direct extraction of the SHA-256-bound official package confirmed that usr/lib/chatgpt/version contains Electron version 42.3.0, distinct from ChatGPT package version 26.810.52044.
• The evidence inventory records reproducible retrieval and hashing rules for mutable OpenAI documentation, decision records, package provenance, and the retained fallback baseline.
• The maintainer contract now separates the bounded two-transaction producer switch from ordinary signed package upgrades.

Validation

• git diff --check 9364b98a1fc4308d9792c2d77c59cb11d49490d0...d883e94e0fe950894b5acc473fd7f0c03af5de31 — passed.
• CodeRabbit and Greptile approved exact head d883e94e0fe950894b5acc473fd7f0c03af5de31; all five review threads are resolved.
• CodeQL, clippy, Rust and smoke tests, the Debian/RPM/pacman/Nix package builds, CodeRabbit, and Greptile pass on the exact head.
• No test files changed because this is documentation-only; the required smoke, package, and Nix CI still ran and passed.

Checklist

• This pull request is ready for review and is no longer a draft.
• I followed CONTRIBUTING.md, kept the change focused, edited source files rather than generated output, and removed unrelated changes.
• The official-app drift implementation item is not applicable to this documentation-only audit.
• No test files changed; I ran the validation listed above and confirmed that required CI checks pass.
• I reviewed the final diff with my coding agent using maximum reasoning effort, addressed all findings, and reran the relevant tests.

Summary by CodeRabbit

• Documentation
  • Added a comprehensive audit comparing the official Linux app package with the fallback baseline.
  • Documented feature coverage across core functionality, projects, profiles, desktop integration, URI handling, Codex, browser, files, plugins, permissions, and updates.
  • Recorded known limitations, accepted warnings, security and privacy considerations, support boundaries, recovery arrangements, and evidence sources.
  • Clarified package provenance and the transition away from the finishing variant.
  • Documented update and rollback procedures, including signed system upgrades and removal of persistent package holds.

📝 Walkthrough

Walkthrough

The pull request adds an official-app parity audit. It retains the validated native repackage, retires the finishing fork, records accepted omissions, updates package authority guidance, removes the persistent package hold, and defines recovery criteria.

Changes

Official app parity

Layer / File(s)	Summary
Parity decision and capability comparison docs/maintainers/research/official-app-parity-2026-08.md	The audit compares the official package with the fallback baseline across product features, desktop integration, URI handling, Codex, browser support, files, plugins, permissions, and update authority. It records Linux Computer Use and other finishing-fork integrations as accepted omissions.
Runtime and security assessment docs/maintainers/research/official-app-parity-2026-08.md	The audit documents security, privacy, package support, AppArmor, sandbox, update, Wayland, and runtime-security findings.
Update authority and maintenance procedure CONTEXT.md, docs/maintainers/package-runtime-maintenance.md	The validated native repackage uses signed CachyOS packages through pacman without a persistent IgnorePkg hold. The fallback has no active authority unless an accepted rollback assigns authority to chatgpt-updater. Maintenance checks package-manager exclusivity, unexpected transactions, database locks, and unblocked routine upgrades.
Recovery criteria and evidence docs/maintainers/research/official-app-parity-2026-08.md	The audit defines recovery and reopen conditions and lists primary evidence sources, package pins, switch evidence, and retirement closeout evidence.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to d883e

This documentation-only change updates the official app parity record and related repository guidance without introducing runtime behavior changes; no actionable merge-blocking risk remains after normal checks and review.

Poem

I’m a rabbit with records in rows,
The native app stays; the old fork goes.
Holds are removed from the update trail,
Evidence and recovery paths prevail.
I thump through the audit, clear and bright.

Greptile Summary

The maintainer documentation now consistently retires the transition-only IgnorePkg hold and directs routine signed CachyOS upgrades through pacman. The package-switch procedure, repository context, and parity audit describe the same steady-state update policy.

Confidence Score: 5/5

No blocking failure remains.

The focused documentation check confirmed that the former persistent package-hold instructions are absent from the current policy and that the updated documents explicitly require routine package-manager upgrades without the hold.

T-Rex Logs

What T-Rex did

• The focused Git-based documentation check was run against base revision 9364b98 and HEAD, and it confirmed the current documentation no longer contains the IgnorePkg hold instruction, resolving the policy conflict.
• The second focused validation confirmed the old affirmative instruction exists only at the base commit and is absent in HEAD across the three documentation files; no source documentation was modified and reproducible artifacts were created under trex-artifacts/.

In `@docs/maintainers/research/official-app-parity-2026-08.md`:
- Around line 215-233: Update the “Primary Sources” section to record retrieval
dates and immutable snapshot references or content hashes for every external
page supporting a parity decision, including the OpenAI documentation links and
other cited web evidence. Keep the existing source links and audit scope intact
while making each cited page’s evidence reproducible.
- Around line 209-213: Synchronize the update-policy documentation before
declaring steady state: either mark routine CachyOS upgrades as pending until
retirement closeout, or update the dependent CONTEXT.md and switch-procedure
guidance to remove or clearly historicalize the transition-only IgnorePkg hold.
Keep the research result unchanged and ensure the documentation stack presents
only one current policy.
- Around line 20-22: Update the durable documentation’s terminology for
Linux-port modules, including the sections covering Computer Use, AppShots, and
Finishing-Fork Convenience Integrations, replacing generic “integration” labels
with “port integration” or “port integrations.” Keep capabilities such as
Computer Use and AppShots distinct from the port integration that adapts them,
and do not describe these modules as Linux features.
- Line 63: Update the “Both compared builds” statement to document the official
.deb artifact evidence: usr/lib/chatgpt/version contains 42.3.0, alongside the
recipe and SHA-256. If that evidence cannot be reproduced, narrow the statement
to comparing product versions only.
