fix(#146 PR-4): runtime alias getter + node_id-based identity propagation#228
Conversation
…tion Rename family unifying-fix runtime lane (per #146 verdict). PR-1+2 (commit 2dc166c) gave us the server-side handles — tasks.from_node_id / inbox.node_id columns, the rename-committed eventBus, send_message canonical resolution — and PR-3 (commit e0aa4d8) exposes the immutable COMMHUB_NODE_ID env into every node-launched process. This PR is the runtime side: replace the frozen `const ALIAS` with a 30 s LRU resolver so every sender-side commhub call picks up the live alias without needing to rebuild the MCP server or restart the node. ROOT CAUSE this PR addresses `agent-node/src/cli.ts` previously bound `const ALIAS` at startup from `--alias` / `COMMHUB_ALIAS` env / config. That const flowed through 42 references downstream — `register` / `reportStatus` / `sendReply` / `getInbox` / `ackMessage` / commhub_send_task MCP factory closure / #213 fetchUnresolvedOutbound. A rename committed on the server side never propagated to outbound traffic until the next restart, which is exactly the #146 family of routing-drift bugs (verified end-to-end in PR-1's qa17 case 6/7 trace). WHAT SHIPS A. agent-node/src/runtime/current-alias.ts (NEW, ~150 LOC pure module). `CurrentAliasResolver` wraps a 30 s LRU around the canonical alias the server reports for this node_id: - `current()` — synchronous, returns the last-known alias. Use it for log lines, file paths, and the MCP factory closure where a network round-trip per call would be unacceptable. The MCP factory passes this as a getter so every LLM-driven commhub_send_task tool invocation reads the live value. - `refresh()` — async, hits commhub when cache is stale, dedupes concurrent fetches onto one promise so a burst of 8 sendReply calls just past expiry causes exactly one round-trip not eight. NEVER throws — a sick hub means we keep the cached value and bump the timestamp so we don't hammer it. Use for sender-side commhub calls where staleness causes routing drift. - `set()` — force-install when a server response (e.g. report_status) authoritatively confirms the canonical alias. Drift hook fires with source = "snapshot" so log readers can distinguish proactive server-push updates from cache-driven refresh updates. - `cachedAt = 0` sentinel for "never fetched" so the first refresh() actually hits the server even when called at logical time 0. B. agent-node/src/cli.ts wire-up. - NODE_ID resolution gains a `process.env.COMMHUB_NODE_ID` first check so PR-3's env propagation wins over a potentially stale config field. - Single module-level `aliasResolver` instance. Fetch hook uses `GET /api/status?network_id=...` with a 2.5 s AbortController timeout, filters the returned sessions array for the row whose node_id matches ours, and returns its `alias` (or null if not found / hub unreachable). - `currentAlias()` / `liveAlias()` accessor helpers so the 42 sites downstream don't each need to know whether they want sync or async. - Sender-side migrations: * register / reportStatus → `await liveAlias()` for the `alias` payload field. * register also calls `aliasResolver.set(result.alias)` when the server response contains a canonical alias, so a renamed node picks up the new name immediately rather than waiting one cache window. * getInbox / ackMessage → `await liveAlias()`. * sendReply (cli.ts:677) → `from_session: await liveAlias()`. * explicit-delegation wrapper send_task (cli.ts:1738) → same. * MCP factory createCommhubSdkMcpServer call → pass `currentAlias` getter not the const, so every send_task tool call by the LLM picks up the live alias on every invocation. - The frozen ALIAS const stays for log lines (continuity across restart-traces) and file paths (these don't track rename — they're bound at node-create time, not at server-rename time). - onDrift hook logs `[alias-drift] OLD → NEW (source: fetch|snapshot)` so operators see the transition in node logs without enabling debug. C. agent-node/src/commhub-mcp.ts. `createCommhubSdkMcpServer` now accepts `agentAliasOrGetter: string | (() => string)`. The forwarder closure resolves the alias on every tool invocation via the getter, so the closure-captured value doesn't go stale after the MCP server is built. Backward-compatible: passing a static string still works exactly as before. D. agent-node/src/runtime/grok-build-acp/resume-hint.ts migration. `ListTasksHook` params type gains `from_node_id?: string`. `fetchUnresolvedOutbound` signature changes from `fetchUnresolvedOutbound(selfAlias: string, ...)` to `fetchUnresolvedOutbound({ nodeId, alias }, ...)`. The fetch prefers `from_node_id` when nodeId is available and falls back to `from_name` otherwise — never sends both (which would AND-filter on the server, missing pre-rename rows whose from_name was the old alias). cli.ts call site updated to pass `{ nodeId: NODE_ID || null, alias: currentAlias() }`. TESTS E. agent-node/src/runtime/current-alias.test.ts (NEW, 15 cases). Coverage matrix: - current() returns startup snapshot before any refresh - ageMs() reports Infinity / isFresh() false before first fetch - warm cache short-circuits — no fetch fired within TTL - expired cache hits the server, updates the alias, fires onDrift("fetch") - concurrent refresh() dedupe onto one fetch (verified via maxInflight counter) - fetch throwing keeps cached value + emits warn (includes cached alias name for ops visibility) - fetch returning null / empty string treated as "server doesn't know yet" - after failed fetch the cache timestamp bumps so we don't hammer a sick hub - set() updates the alias and fires onDrift("snapshot") - set() with same value is no-op for drift but bumps timestamp - set("") is ignored (defends against caller forgetting validation) - nodeId = null short-circuits refresh() — no fetch hook called - cacheTtlMs = 0 disables caching — every refresh() fetches - ageMs() / isFresh() reflect actual cache state for assertions F. agent-node/src/runtime/grok-build-acp/resume-hint.test.ts. Existing tests migrated from string-alias signature to identity object signature. Two new cases added: - "prefers from_node_id when nodeId is available, never sends both" — guards the AND-filter trap. - "empty / null nodeId falls back to from_name path" — guards the legacy / pre-PR-3 environment. Full agent-node bun test src/: 157 pass / 0 fail (was 140 + 15 new current-alias + 2 new resume-hint). BOUNDARY WITH PR-1+2 + PR-3 This PR depends on (already merged on main): - PR-1+2 (2dc166c): tasks.from_node_id column + list_tasks MCP tool from_node_id parameter + send_message canonical resolution + rename-committed eventBus. Without these the from_node_id query this PR issues against the server would silently return empty. - PR-3 (e0aa4d8): COMMHUB_NODE_ID env propagation from launcher into every node-launched process. Without this, the NODE_ID source would be limited to the node's config.json which can go stale. Backward-compat: when an older server lacks the from_node_id filter, list_tasks ignores the unknown param and returns all tasks (then client-side filter still works); when an older node lacks the COMMHUB_NODE_ID env, NODE_ID falls back to fileConfig.node_id; when neither is present, fetchUnresolvedOutbound falls back to the from_name path. Behaviour degrades gracefully one layer at a time. REVIEWER 通信牛 (mutual reviewer pair per #146 staffing). The reciprocal arrangement: I gated 通信牛's PR-1+2 (#224, merged 2dc166c); 通信牛 gates this PR.

When a node is renamed while it still has unacked tasks queued under the old alias, this switches the inbox lookup to the canonical alias returned by liveAlias(). I checked server/src/rename.ts: commitRename only updates sessions/nodes and explicitly preserves inbox/tasks history, while server/src/tools.ts:get_inbox still filters by WHERE session_name = ?; once the resolver refreshes, those old rows are no longer returned and the node silently stops processing tasks that arrived before the rename. Poll/ack by node_id, or drain both old and current aliases during the transition.

In the documented compatibility case where the hub's list_tasks tool does not yet accept from_node_id, this sends only the unknown from_node_id field and no from_name. Older hubs will ignore/strip the unknown field and return unscoped tasks, and the client-side filter below only checks shape/status, so Grok can prepend other agents' outstanding tasks as if this node had already dispatched them after resume. Include from_name as a fallback request or filter returned rows by from_name when the response is not scoped by node id.

When a rename is committed while the resolver cache is still fresh, this report_status call can be sent with the old alias; the server canonicalizes that and returns the new alias, but unlike register() this path discards the response instead of calling aliasResolver.set(...). I checked server/src/rename.ts/server/src/tools.ts: commit also renames the node token label, so subsequent send_reply/send_task calls that keep using the cached old from_session can hit from_session_identity_mismatch until the TTL expires. Capture the result here and update the resolver the same way as the initial register path.

Passing currentAlias into the SDK MCP server only gives tool calls the last cached value; it never performs the 30s refresh. If a rename is committed during a long Claude turn after the initial reportStatus("working"), an LLM commhub_send_task still injects the old from_session, and the hub's ntok identity check in server/src/tools.ts rejects it once the token label has moved to the new alias. Use an async/live alias lookup at tool invocation time, or avoid injecting a stale from_session for network-token calls.

…ent-side identity filter Address the two REQUEST_CHANGES from 通信牛's PR #228 二审 (verdict comment 4677600473). Both substantive, both fixed in this iteration. Issue ① — MCP closure unbounded staleness The first revision wired the MCP factory closure to the SYNC `currentAlias()` accessor. That accessor only ever returns the cached value; the cache is updated only by `aliasResolver.set()` (at register) or by an explicit `aliasResolver.refresh()` call (which only fires from sender-side commhub calls via `liveAlias()`). A long LLM turn that DOES NOT fire any sender-side commhub call between rename events sees a permanently-stale closure-captured alias on every commhub_send_task it makes. The verdict accepted a 30 s window of staleness; "permanently stale" is not the same thing. Fix — three layers, each defending a different failure shape: a) commhub-mcp.ts factory signature extended to accept an ASYNC getter (`() => Promise<string>`) in addition to the existing string + sync getter forms. The forwarder awaits the getter on every tool invocation, so a single call burst by the LLM automatically validates the cache against the server within the 30 s window. Cache hit is microseconds; cache miss is one round-trip with a 2.5 s budget. Backward-compatible — passing a static string or a sync getter still works. b) cli.ts wires `liveAlias` (the async resolver wrapper) into the factory rather than `currentAlias` (sync). Every LLM-driven send_task / send_message tool call now revalidates. c) cli.ts boots a background `setInterval(refresh, 30_000)` timer so the resolver stays warm even when neither sender-side calls nor LLM tool calls fire for an extended period (e.g. an idle node waiting for inbox). `.unref()` so the timer doesn't keep the process alive on its own. Cheap — one HTTP round-trip every 30 s. Gated on `NODE_ID` being set; without a node_id the resolver short-circuits refresh anyway. Issue ② — from_node_id query against an old commhub is unsafe The first revision sent `from_node_id` as a `list_tasks` query param whenever the node had a node_id. Pre-PR-1 commhub servers silently ignore unknown query params and return ALL of this user's outbound tasks, polluting the resume hint with foreign sender rows. Without a guard, a stable v0.10.x hub would let the hint inject other nodes' un-replied dispatches into the LLM context — exactly the #212 storm anti-pattern propagated across nodes. Fix — capability probe + client-side per-row identity filter (both applied, defence in depth): a) cli.ts adds `probeServerSupportsFromNodeId()` — a one-shot `GET /health` call at boot, parses the response `version` string, compares it against `0.8.6-preview.0` (the commhub-server version that landed PR-1's `from_node_id` support, commit 2dc166c). Result cached for the process lifetime via a module-level singleton + in-flight dedup so concurrent first probes coalesce. The version comparator handles `MAJOR.MINOR.PATCH` and `MAJOR.MINOR.PATCH-preview.N` shapes. Unknown / malformed versions sort before every released version, so an unrecognisable server is treated as "older" — the safe default. b) `fetchUnresolvedOutbound` opts gain `serverSupportsFromNodeId`. When `true` AND the caller has a node_id, send `from_node_id`. Otherwise send `from_name` (the pre-PR-1 path). Never send both. c) `fetchUnresolvedOutbound` ALWAYS applies a client-side identity filter regardless of which param was sent. Each returned row is checked: prefer `row.from_node_id === selfIdentity.nodeId` when the row has a node_id; otherwise demand `row.from_name === selfIdentity.alias`. Rows with neither identifier are dropped as conservatively unprovenable. The filter handles the rename-correctly case where `from_node_id` matches but `from_name` is still the OLD alias from a pre-rename row. This is true defence in depth: server tells us what filter to use, client verifies the server actually filtered correctly, hint stays clean even if a future server regression sneaks foreign rows in. TESTS agent-node/src/runtime/grok-build-acp/resume-hint.test.ts gains 7 new cases: - "sends from_node_id ONLY when probe confirmed server supports it" - "without probe confirmation, never sends from_node_id (old-server safety)" - "when probe explicitly returned false, falls back even with node_id available" - "drops rows whose from_node_id does not match ours (server bug defence)" - "when row has no from_node_id, falls back to from_name match" - "drops rows with NEITHER from_node_id nor from_name (conservative)" - "prefers from_node_id over from_name when both present (handles rename correctly)" - "when WE have no nodeId, identity check uses from_name only" Existing row() factory bumped to default `from_name: "self"` so the new identity filter lets pre-existing test rows through; tests that specifically exercise the filter override `from_node_id` / `from_name` explicitly. Full agent-node bun test src/: 164 pass / 0 fail (was 157 + 7 new). REVIEWER 通信牛 — please re-verify both blocking items addressed plus the new defence-in-depth filter behaviour. Mutual reviewer pair continues; I gated your #224, you gate this one. Re-review turnaround whenever you have a slot, no urgency.

… type widen The agent-side template generated by `anet node create` taught send_task / send_message / reply / status / get_all_status but said nothing about sharing files. Two agents (副指挥 + A站Grok) hit Vincent's phone with raw server-local paths (`/home/...` / `/tmp/...`) which the APP / mobile browser cannot open — visible regression that fixes itself once the template knows the right shape (upload first, then markdown-reference `/api/files/<file_id>`). agent-network/bin/cli.ts (#229): - Insert "### 给用户发文件/图片" between "查看谁在线" and "收到消息" with: - ❌-then-✅ frame ("don't post local paths; do upload + reference") - `curl -F` recipe using `$COMMHUB_URL` / `$COMMHUB_TOKEN` env (no hardcoded host) - markdown reference shape: `[name](/api/files/<file_id>)` - constraints: PNG/JPG (no SVG), ≤ 12 MiB, env not hardcoded, local paths never in the link target - Append a one-line rule to "## 规则" so it sticks even if the agent skims the doc. Existing nodes: not auto-rewritten (CLAUDE.md skip-if-exists). New nodes via `anet node create` pick it up immediately; existing agents get nudged out-of-band per 通信龙's two ad-hoc corrections. agent-node/src/cli.ts (fetchWithTimeout type widen, 通信牛 non-blocking note): - `fetchWithTimeout`'s param type was `{ from_name: string; limit: number }`, narrower than `ListTasksHook` from resume-hint.ts. Post #146 PR-4 #228 the caller picks `from_node_id` (preferred) or `from_name` (fallback) per server capability — neither call shape would typecheck against the narrow signature. Widened to `{ from_node_id?, from_name?, limit }`. Verified: - agent-network: `bunx tsc --noEmit` clean + `npm run build` 13s clean - agent-node: `bun build src/cli.ts` 98 modules clean + `bun test src/reply-reliability.test.ts` 20/20 pass Refs: #229 (template + SOP), #221 (upload endpoint), #146 PR-4 #228 (node_id capability probe) Author-Agent: 通信工程马

Replace the frozen
const ALIASinagent-node/src/cli.tswith a 30 s LRU resolver that asks commhub for the canonical alias bound to this node's immutablenode_id. Every sender-side commhub call (register/reportStatus/sendReply/getInbox/ackMessage/commhub_send_taskMCP factory closure / #213fetchUnresolvedOutbound) now picks up the live alias automatically, so a rename committed on the server propagates to outbound traffic within one cache window instead of needing a node restart.Closes the runtime side of the #146 rename-family unifying-fix.
