- Line 123: Update connectManagedResourceStream to reject requests with
headers.Authorization when the URL protocol is not https: before calling fetch,
while preserving existing behavior for other requests. Document this HTTPS
requirement in the bearer-token client guidance.
In `@gateway/reauthorize.go`:
- Around line 60-77: Update the reauthorization goroutine around the check
failure branch and the result handling after g.cycle so cancellation caused by
cycle completion is distinguished from a genuine authorization failure: when a
check returns, inspect cycleCtx.Err() and avoid converting that cancellation
into a terminal StreamError, allowing the original recoverable cycle result such
as ErrWatchClosed to propagate. Preserve fail-closed behavior for checks that
fail while the cycle remains active, and add a regression test covering a
blocked Authorizer with a concurrent recoverable cycle completion.

- Around line 32-33: Update the response metadata handling near reconcile so it
accepts both redactedPaths and the legacy redacted array, preferring
redactedPaths when present and falling back to redacted otherwise. Preserve
undefined metadata when neither property is supplied, then pass the selected
value through reconcile’s redactedPaths option.

both “retrying” and “connecting” after the retry delay, while preserving
validation of the connector’s recovery state.
In `@README.md`:
- Line 112: Update the example around connectManagedResourceStream to retain the
returned ManagedStreamHandle and invoke close() during host/view teardown,
ensuring the stream and retry loop stop when the view is disposed;
alternatively, explicitly document that the example remains active for the full
page lifetime.

CodeRabbit follow-through in d521092: each inline finding now has a reply with the implemented correction or an explicit design decision. Also addressed the review-summary GET-test suggestion with TestHostGETReturnsProjectedEnvelope: it checks the object/redactedPaths envelope, retained UID/RV/data, and stripped managedFields/last-applied metadata. For the docstring-coverage warning, I am not adding generic comments solely to meet the bot's 80% heuristic. The public lifecycle/save/authorization contracts and host responsibilities are documented; a specific missing API guarantee warrants a focused correction, but blanket test/helper docstrings are not a merge gate. The HTTPS guidance is now explicit, while transport enforcement remains host-owned. All short-term fixes are implemented; no additional review-driven feature work is deferred silently. The already scoped normative-spec, upstream-continuation and real-API hardening follow-ups remain in proposal 0006. Local task verify passed (104 client tests, Vue, Go, wire/browser, lint, fixtures and package checks). CI is running on d521092. CodeRabbit has reported a review quota limit, so these replies and local verification do not claim a fresh bot approval of the final commit. |

Live editors currently stop recovering after sequence gaps, and quiet shared streams can retain access until their next snapshot cycle. The save guide also discouraged resourceVersion preconditions, leaving narrow merge patches vulnerable to concurrent edits.
This change adds:
SubjectAccessReviewAuthorizeras the canonical name, with a tested deprecatedSSARAuthorizeralias.The wire protocol and existing merge/shared-watch implementations remain compatible. Timed authorization is opt-in. The core client has no new runtime dependencies; Vue dependencies stay in the private example. Host callbacks must honor cancellation; writes, credentials, and application policy remain host-owned.
Validation: 104 client tests, two Vue tests with typechecking, Go suites including gateway race checks, 18 browser tests across module and bundle entry points (including recovery through the visible editor), wire tests, lint, fixture consistency, package validation, and
TestConditionalSaveConflictagainst a real Kubernetes API server. Regression tests cover cycle teardown during reauthorization, concurrent explicit denial, retry replenishment after sustained health, health-timer reset, redaction reconciliation, and saving after deletion.Design follow-up: proposals 0005 and 0006 document the Kubernetes stream/save tradeoffs, client projection choices, and the proposed implementation split. The save-outcome corrections and focused Gateway.Stream regression are now implemented. The normative convergence amendment, upstream continuation, timer-test simplification, real-API status/save composition, and UID-race classification remain separate follow-ups. Local documentation validation checked links and rendered all ten Mermaid diagrams.
Summary by CodeRabbit
Final correction: the copyable editor distinguishes draft conflicts, stale versions, recovery and unavailable resources. A required host live-state callback gates saving; after a refused reconciliation, another click performs only a guarded read until an accepted live read permits a fresh intent. This deliberately allows an extra read without guessing why a response was refused or adding subscriptions. Adopter documentation explains safe rejection versus progress for every projection. Direct example tests cover outcomes, snapshot races, unknown redactions, request serialization and errors. The public Gateway.Stream regression verifies recoverable teardown during reauthorization through the next reset/synced cycle.
task verifyand gateway race tests passed locally.CodeRabbit follow-through: reconciliation accepts both supported redaction formats, the README demonstrates connection cleanup, and the browser recovery assertion accepts the valid connecting transition. A focused GET-envelope test covers the host response contract. Bearer-token HTTPS enforcement is explicitly documented as host-owned. Every inline review thread has a response; the docstring-percentage warning has an explained scope decision.
