docs: re-center on watch streams and a native watch direction - #59

Conversation
Priority 4 of proposal 0006 asks for the exhaustion transition, and the choice between client-go's utilities and a small loop, to be settled before implementation. This adds that design, and nothing else. - Continuation lives in gateway/kube's watcher, beneath the gateway and SharedBackend, so one reopen serves every subscriber and the wire is unchanged. - client-go's RetryWatcher is not used: it cannot own the streaming list's initial snapshot, retries most failures without a bound, and makes 401/403 terminal where a fresh cycle can refresh credentials. - The checkpoint is the last upstream event or bookmark resourceVersion, taken before projection. Continuation is armed only after the snapshot boundary. - 410 resyncs, 401/403 start a fresh cycle, and transient failures get at most three backoff reopens. A watch that dies before an event counts as a failure. Then ErrWatchClosed hands over to the gateway's existing quick-end rule and the client's bounded budget. - The authorization and credential-lifetime consequences are stated, with one open question (capping continuation age), and an evidence and measurement plan is given.

…atch direction Lead with live resource views and treat editing as an optional layer. Record native Kubernetes watch JSON through a host proxy as the preferred transport direction in a new field report, slim completed proposals and remove superseded field reports and the duplicate Vue guide.

RetryWatchercomparison by failure phase.
RetryWatchertreats open failures and in-stream error events differently: it retries an opening 410 and an in-stream 401/403, but stops on an in-stream 410 and on opening 401/403. The current wording describes these statuses as if each has one retry outcome. State the behaviors by phase before using them to justify the custom loop.

Keep bookmark-only reconnects inside the failure budget.
A bookmark resets the counter under this rule. If each reopened watch emits a bookmark and then closes immediately, the counter resets on every reopen, so the watcher can reopen indefinitely without backoff or returning ErrWatchClosed to the gateway. Reset the count only after a watch remains useful for a minimum interval, or separately bound rapid closes.

… slice Describe the native host-proxy source and the gateway's projected views as a choice of guarantees rather than a framing preference, note that the SSE connector's HTTP 4xx rule does not apply to native 410 history expiry, and narrow the next native work to a read-only LIST/WATCH viewer that re-lists on reconnect and reuses the existing lifecycle and read-only store.

Direction change. Stacked on #58 (→ #57 → #55 → #54 → #53). This PR started as a design proposal for upstream continuation. It now also changes what krm-stream says it is and where it is going.
The new direction
fetch, reusing the same connection lifecycle and resource store, with no SSE wrapper in between. The gateway stays for what only it provides: projection/redaction, update suppression and shared upstream watches.What's in it
b5cc779: the upstream continuation design for the gateway's Kubernetes backend, added to proposal 0006 (unchanged from the original PR).1cdf1c4: re-centres the docs on watch-first, as described above.docs/field-reports/third-our-identity.md, the request: native watch connector, recovery acceptance, native/full/spec comparison and save progress under suppressed churn.docs/vue.md; the Vue guidance now lives inexamples/vue.Docs only, no behaviour change. Local link and anchor check passes.
Next
The first native connector slice is read-only. It re-lists on every reconnect, which is the same contract gateway SSE has today. Resume, streaming lists and native editing come later.
