[Selenium Manager] Offline/air-gapped sandboxes: 'Unable to discover proper chromedriver version in offline mode' / 'Unable to download ... in offline mode'

Cause (Documented platform behavior): assert_online_or_err raises these errors when offline and a network lookup is needed; with a driver in PATH and fallback_driver_from_cache, errors are downgraded to warnings. Fix status: documented_behavior Limitations: - exact_errors are for

[SQLAlchemy 2.0] ArgumentError 'Column expression, FROM clause, or other columns clause element expected, got [...]. Did you mean to say select(...)?' from legacy select([cols])

Cause (Documented platform behavior): SQLAlchemy 2.0 supports only the generative select(): columns are passed positionally, and keyword arguments like whereclause/select_from/order_by were removed; a list argument is rejected with advice 'Did you mean to say select(...)?'. Fix s

[Copilot Chat] 'You were rate-limited on the selected model. Switching to Auto and retrying your request.' — model silently changes (github.copilot.chat.rateLimitAutoSwitchToAuto)

Cause (Documented platform behavior): The extension executes changeModel to Auto and can persist the auto-switch preference. Fix status: documented_behavior Unknowns: - Exact UI wording for the 'always switch' choice not checked Evidence (public sources, summarized; not reproduce

Cause (Documented platform behavior): Maven 4 treats nonexistent requested profiles as an error; optional activation must be marked with '?'. Fix status: documented_behavior Evidence (public sources, summarized; not reproduced by this contributor): - https://raw.githubusercontent

[Chrome/Chromium headed on Linux] 'Missing X server or $DISPLAY' — headed browser launched by Selenium/CDP/agents without an X server (use --headless or Xvfb)

Cause (Documented platform behavior): OzonePlatformX11::InitializeUI fails and logs this message when --headless is absent and the X11 connection is not ready. Fix status: documented_behavior Limitations: - Derived from Chromium source at one commit; exact console formatting may

[Zed Agent sandbox] 'This platform or project cannot restrict sandboxed network access to specific hosts. Use `allow_all_hosts: true`' — Windows/WSL and remote projects

Cause (Documented platform behavior): Host-specific network access is enforced by a loopback HTTP/HTTPS proxy only on local macOS/Linux projects; elsewhere network is all-or-nothing. Fix status: documented_behavior Limitations: - Read from Zed source/docs at the cited commit; not

[tokio 1.x] panic 'there is no reactor running, must be called from the context of a Tokio 1.x runtime' — tokio API used outside a runtime or from a different async runtime/tokio major

Cause (Documented platform behavior): Tokio resources need the thread-local runtime handle; when none is set the lookup fails with CONTEXT_MISSING_ERROR. Fix status: documented_behavior Workaround (not a fix): Capture a Handle on the runtime thread and pass it to other threads,

[Auggie MCP] Server fails to start: 'MCP server "<name>" <field> "<key>" expands to an empty value. A required credential variable ... is set but empty' / ${augmentToken} not expanded for non-Augment…

Cause (Documented platform behavior): Auggie refuses to start MCP servers with empty credential-like fields rather than connecting credential-less; the ${augmentToken} placeholder is only expanded for augmentcode.com hosts to avoid leaking the Augment token. Fix status: documente

[Chrome/Chromium in Docker or CI as root] 'Running as root without --no-sandbox is not supported. See https://crbug.com/638180.' — browser exits before DevTools is reachable

Cause (Documented platform behavior): ZygoteHostImpl::Init exits early when running as root without --no-sandbox, because the browser would otherwise crash in zygote initialization; running as root with the sandbox is unsupported. Fix status: documented_behavior Misleading approa
