Extend the local plugin system's host<->plugin contract with generic,
capability-neutral facilities, so transport plugins can be built on top
without embedding plugin-specific logic in the host.
Host services (plugin dials a broker-provided HostService gRPC):
- per-plugin namespaced KV store (key/value size and TTL bounded)
- account directory: ListAccounts + ResolveOutboundIdentity, restricted to
the accounts a plugin's declared capability already covers
- InitHostServices lifecycle hook; plugins that don't implement it run
unchanged and are simply offered no host services
Read-only runtime status channel:
- HealthResponse gains an opaque, plugin-defined status_json produced
passively (no config apply, no upstream call, no side effects)
- GET /admin/plugins/:id/status (ungated) and the plugin.status UI-bridge
verb map to Health, so a status UI can poll live state without a step-up
prompt or a "test" side effect
- config.test no longer force-shows a host success toast; the plugin UI owns
result presentation, so plugins that read status do not spam toasts
Document the UI-bridge verb taxonomy (read vs mutate/test gating) and the
status contract under pkg/pluginapi.
Resolves three conflicts, all of the "both branches appended to the same
block" shape. Every one is resolved as a union of both sides; nothing from
either parent is dropped.
- handler/admin/setting_handler_update.go: keep ChannelMonitorHideThroughput
(V2) alongside GrokDefaultTextModel / GrokCrossClientModelMapEnabled /
GrokDefaultBaseURLMode (#5408). UpdateSettings writes every key on each
save, so dropping either side would reset those settings to zero values.
- service/domain_constants.go: keep SettingKeyChannelMonitorHideThroughput
and the three SettingKeyGrok* constants.
- repository/migrations_runner.go: keep the 195 checksum rule (V2) and the
218/219/220 rules (#5408).
Review follow-ups on the reset-credit caching flow:
- Recover account state BEFORE (and independently of) the reset-credit
display cache. A failed cache refresh could previously abort the run and
leave the account rate-limited — the very reason the credit was spent
(#3672 / #3740). The recovered account row is now returned even when the
cache refresh fails.
- Run the post-reset bookkeeping on a detached, time-boxed context and give
the panel reset call a larger timeout. A client abort no longer strands a
consumed (non-refundable) credit with an unrecovered account, and the
chained upstream calls can no longer exceed the client timeout and invite a
retry that spends a second credit.
- Persist the reset-credit snapshot through POST /accounts/:id/quota/refresh
instead of a side-effecting GET flag, so the write is covered by the audit
middleware. A rejected snapshot write now degrades to cache_persisted=false
instead of turning a successful upstream read into a 502 that left the card
without a credit count and the reset button permanently disabled.
- Reject snapshots whose positive count carries no expiration entries, and
drop expired credits (clamping the count) when rehydrating, so a stale
cache can no longer light up the reset button.
- Keep nil quota / rate-limit services nil in the handler's interface fields;
storing a nil *Service made the "not enabled" guards non-nil.
- Time-box the usage-refresh suppression and reuse handleAccountUpdated so the
patched row also enters the auto-refresh silent window.
Admins often recreate groups with the same pricing, routing, and account membership. A server-side duplicate creates an inactive copy for review, preserves eligible account priorities, and recovers ambiguous retries without creating extra groups.
Constraint: Group has no neutral JSON metadata field for durable operation recovery
Constraint: Model routing references account IDs, so copied configuration requires matching bindings
Rejected: Rebuild from the list response | it omits configuration and account priority details
Rejected: Store operation identity in business configuration | it would pollute real group settings
Confidence: high
Scope-risk: moderate
Reversibility: clean
Directive: Keep duplicated groups inactive until an administrator reviews the copied configuration
Tested: Go unit and full tests, go vet, integration-tag compile, frontend Vitest, lint, typecheck, production build, and Playwright duplicate flow
Not-tested: PostgreSQL container integration locally because Docker is unavailable; CI will execute the database-backed suite
Admins often recreate monitors with the same endpoint, model, and request settings. A server-side duplicate keeps the stored API key out of the browser, creates a disabled copy for review, and uses stable operation identity to recover ambiguous retries without creating extra rows.
Constraint: Stored monitor API keys must never be returned to the browser
Constraint: Applying a request template must preserve internal duplicate recovery metadata
Rejected: Rebuild the monitor from list data | list responses only contain a masked API key
Rejected: Copy runtime state and history | a duplicate should start as an unverified configuration
Confidence: high
Scope-risk: moderate
Reversibility: clean
Directive: Keep duplicated monitors disabled until an administrator reviews and enables them
Tested: Go unit tests for repository, service, and admin handler; integration-tag compile; go vet; golangci-lint v2.9; frontend Vitest, ESLint, typecheck, production build; Playwright duplicate flow
Not-tested: PostgreSQL container integration locally because Docker is unavailable; CI will execute the database-backed suite
Admins often need another account with the same provider and routing configuration. Duplicate on the server so credentials never return to the browser, preserve exact group priorities atomically, start the copy paused, and recover the same copy after ambiguous idempotency-store failures.
Constraint: Admin account responses redact credentials, so duplication must remain server-side
Constraint: OAuth and setup-token credentials rotate and must not be shared across account rows
Rejected: Copy raw account JSON to the clipboard | exposes credentials outside the server
Rejected: Duplicate rotating credentials | account-scoped refresh locks can race token rotation
Confidence: high
Scope-risk: moderate
Reversibility: clean
Directive: Keep copies paused, avoid automatic upstream probes, and exclude rotating credential types unless token ownership is redesigned
Tested: Targeted Go tests, Go vet, server build; frontend lint, typecheck, Vitest suite, production build; integration test compiled
Not-tested: Docker-backed PostgreSQL execution because Docker is unavailable
