Preserve authenticated home/account navigation and guarded mobile sidebar swipes. Keep both browser task selections. Complete the new account fixture contract and synchronize lifecycle probes on visible registered-key results, without changing their success or security assertions.
Capture the shared authentication stamp as well as generation before dispatch and across response/confirmation/application awaits. Do not let stale setup failure reconciliation overwrite a newer tab's stamp. Add no-event-yet logout and account-change regressions for activation and setup, including prompt, pre-complete and post-dispatch confirmation boundaries.
Addresses MR AC4_CROSS_TAB_ACTIVATION. Validation: activation21/setup40 narrow tests; Web720 unit+625 component, check0/0/build, activation and hosting browser suites; root check/fmt/diff; both explicit real Backend browser suites including native CTAP2. Existing Server exclusions and 15 identical baseline naming findings remain unchanged. No verifier, binding, migration or rendering contract weakened.
Fence displayed identity and native prompt generations, classify secret-free outcomes, recover atomic addition receipts without restoring old credentials, and expose truthful own-key verification metadata. Preserve required verifier and enrollment authority boundaries. Include real-store, production browser, native CTAP2 and visible responsive regressions.
Validation: root check/fmt; API 115; passkey security 25; Web unit 712/component 605; auth/entry/activation/hosting browsers; product auth E2E 8 and two explicit browser suites. Server suite: 1262 lib+12 CLI, 3 ignored and 2 environment-specific exclusions. State-name checker retains 15 byte-identical baseline findings; no new exceptions. Physical keys/mobile and hosted CI remain unverified.
Project alias, cwd, scope and command ceilings from actual sessions. Bind initial attachment cwd once in the shared broker/router while keeping root-relative delegation and detach generations. Preserve caller coordinates across reads, searches, checked checkout and commands; keep provider authorization and symlink boundaries.
Connect real SubWorkers, all filesystem Tools, scoped aliases, HTTP providers and limited Host grants in permanent regressions. Validated related normal suites (workdir http-client, tools, worker, worker-runtime, server-api typescript, fs-operation), workspace-server normal suite (1272 passed, 3 existing ignores), root check, product binary builds, rustdoc/doctests, generated contract checks, format and state-contract names. Test roots are checkout-local; Git parent discovery requires GIT_CEILING_DIRECTORIES at TMPDIR, confirmed against exact b860 baseline.
Expose an optional private same-uid Unix operator adapter and JSONL serve/attach CLI using the production Standalone Profile, store, restore lease and shutdown lifecycle. Remove direct Worker subprocess/discovery/readiness/controller sockets and parent socket callbacks; retain metadata-only peer registration and legacy safety readers.
Validated real Host/client input, events, provenance, disconnect, admitted shutdown and shared production restore/duplicate exclusion; normal standalone/worker/manifest/protocol/client/yoi/tui/server tests, root check, rustdoc, fmt and state-contract audit. Runtime lib: 476 passed, damaged_checkout_does_not_block_restore_but_is_rejected_when_used fails at missing_git diagnostic; unchanged restore logic, not relaxed or retried. Runtime bins/docs pass.
Integrate the published T773 audit contract without overwriting operation outcomes. Preserve bounded admission, send refusal, response loss/timeout and invalid result reasons independently of audit failures and request stages. Signed HTTP/SQLite/log fault tests pass (10), API logging 14 and relevant focused assertions pass. Root check, docs, generated artifacts, fmt/diff and state-contract naming checks pass. Full six-package normal suite ran with no-fail-fast but is not green: long Unix socket fixture paths and existing shared close assertion plus environment-isolation failures are recorded in target/t774 logs. Isolated focused checks resolved the latter; socket validation requires a granted shorter test root. This is a partial checkpoint, not a reviewed completion.
Keep bounded reasons and derived failure stages separate from public classification. Reject provider-authored raw error text on transport decoding. Preserve identity mismatch when cleanup fails and retain its handle for explicit close without opening again. Add signed Runtime HTTP, Registry/API logging, remote mismatch, authorization no-dispatch and deferred fault coverage. Focused tests and Workdir suite pass; full-source validation follows T773 audit contract merge.
