fix: define content and redaction convergence while suppressed writes retain older RVs - #33

…ions Delivered resourceVersions belong to delivered revisions and remain valid conditional-write preconditions, without freshness or downstream resume guarantees. Final bookkeeping-only and spec-projected status-only changes may be suppressed while visible content converges and held versions remain older. Wire emissions are unchanged.
📝 WalkthroughWalkthroughThe change defines visible-state convergence for projected Kubernetes resources, including suppression of final bookkeeping and status-only writes, delivery of Secret redaction changes, conformance fixtures, gateway and client tests, and documentation for stale conditional saves.

Priority: ⬇️ Low Estimated code review effort: 3 (Moderate) | ~25 minutes Change: Other Merge Risk: 🔵 Low · up to The implementation is mergeable, but the proposal should tie status suppression to projection choice and the README should accurately scope when browser clients may receive credentials. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

Keep the positional guarantee while excluding RV from content equality. Add final Secret rotation evidence and explicit suppression observations, consolidate contract prose, and illustrate the read/edit/save architecture and stale-version behavior.

Tie status suppression to the effective projection.
krm-spec/v1 suppresses status-only updates because it ignores status; a consumer's rendering choice does not control the gateway projection. A status-blind consumer can still receive krm-full/v1 and receive status-only events. Name krm-spec/v1 or “a projection that ignores status” here to keep the proposal aligned with the specification.
Proposed wording
- upstream update when projected content excluding `metadata.resourceVersion`, plus redaction records, is unchanged. The goal is not merely smaller status events; a consumer that does not render status receives **no event** for status-only churn.

Qualify the browser credential guarantee.
README.md says that the browser never receives a Kubernetes credential. However, docs/adopting.md Lines 123-128 and packages/krm-stream/README.md Lines 56-60 document an intentionally token-bearing browser mode. Scope this sentence to the default host-owned cookie flow. Otherwise, the documentation gives users an incorrect security boundary.
Proposed wording
- The browser never receives a Kubernetes credential or a raw API-server URL.

Move the quiet-stream explanation into the saving guide and keep links at adoption entry points. Tighten handoff wording and make suppression regression failures report unexpected events before timeout details, with a shorter test deadline.

A final bookkeeping-only write, or status-only write under
krm-spec/v1, is already suppressed even when it advances the upstream RV. The former whole-object equality wording promised more than those emissions provide.Define the visible comparison as projected content excluding
metadata.resourceVersion, plus per-connection redaction records. Preserve the existing guarantee immediately aftersyncedand each subsequent delivered update at its corresponding logical stream position. Catching up after upstream changes stop is explanatory, not a prerequisite for the invariant. Delivered RVs belong to delivered revisions and remain valid conditional-write preconditions, with no freshness or downstream resume guarantee.Validation:
task fixtures-check,task test(111 client tests, 2 Vue tests and both Go modules),task lint, andtask e2e-wirepassed. Relative documentation links/anchors checked; a temporary Go overlay disabling suppression made all three projection tests fail with the unexpected event sequence in 6 seconds total; both changed Mermaid diagrams rendered and visually inspected in Chromium.
