+# TASK-442: one routing decision per non-rule message
+
+Status: design and benchmark preparation, 2026-10-24. Production integration
+waits for measured LiteLLM latency and a selected model. No model is selected.
+
+## Contract
+
+Explicit mentions, owned rows/TASK/PR references and live claimed-thread rules
+remain authoritative and do not call a model. If any rule addresses a seat,
+route those wakes and deliver other eligible recipients their normal digest.
+Only a message with no rule match is eligible for classification. Rule lookup
+failure is uncertainty, so retain digest and skip the model rather than asking
+it to reconstruct missing authorization evidence.
+
+The per-pod flag starts disabled. Disabled means today's rules and receipt
+policy, with no extra calls. Enabling it explicitly selects model routing for
+non-rule ambient activity; it must not change explicit addressing or DM routing.
+The classifier never assigns/reassigns a task, acquires a claim or impersonates
+an owner. Its owner field is attribution metadata, not write authority.
+
+## Decision boundary
+
+1. Persist the message and resolve the existing recipient/visibility/thread
+   scope. No cross-pod context or private memory enters the prompt.
+2. Resolve deterministic rules once. A rule hit bypasses inference entirely.
+3. For a non-rule message, reserve one decision record under unique
+   `(podId, messageId, policyRevision)`. Concurrent producers share that record;
+   neither each target nor each backend replica makes another call. Reservation
+   failure goes to digest. A crashed reservation has a bounded lease and a
+   durable digest fallback; it cannot hold message delivery forever.
+4. One LiteLLM request with an end-to-end 2,000 ms deadline, no automatic retry,
+   tool use or alternate-model fallback. The selected route/key must disable
+   provider/router fallbacks; record the actual upstream deployment from proxy
+   logs, because the requested model name alone does not establish identity.
+5. Validate the JSON locally, even when the provider claims strict schema.
+   Unknown IDs, extra keys, duplicate targets, over three wakes, wrong owner
+   kind/ID pairing, truncation, refusal, HTTP error and timeout all become
+   `{wake:[], digest:true, owner:{kind:'none',id:null}}`.
+6. Recheck active installation, pod visibility and current thread exclusions
+   before committing any model wake. A late result cannot override a fallback
+   already committed by the deadline. Use idempotent receipt keys so producer
+   retries cannot duplicate the chosen effects.
+
+For a valid decision, `wake` names up to three eligible seats. `digest` governs
+non-woken eligible seats; false means no extra ambient receipt, not deletion of
+the source message or existing unread events. Woken seats still get the actual
+message through the established addressed-event frame and claim discipline.
+Author self-wakes, bot-loop controls and muted/unfollowed-thread scope remain
+enforced outside the model. A human owner may be attributed but is never an
+agent wake target.
+
+Implementation surfaces: `agentMentionService.enqueueMentions` and its ambient
+fan-out; `messageDeliveryModeService.addressedMessageTargets` remains the rule
+floor. Add an isolated decision service and a durable decision model. Do not
+send classifier traffic through `llmService.generate` without first removing
+its provider-fallback behavior for this call. A dedicated LiteLLM-only boundary
+retains usage, deadline and deployment attribution.
+
+## Prompt and schema
+
+The benchmark's `SYSTEM` string and `decisionSchema` in
+[`scripts/benchmark-wake-router.mjs`](../../scripts/benchmark-wake-router.mjs)
+are the executable proposal. All message text, task titles and context strings
+are untrusted data in a separate JSON user message. No tools or secrets.
+
+Context contains `seats:[{id,role}]`, `humans:[{id}]`, current open
+`rows:[{id,title,assignee,prUrl}]`, live `claims:[{threadId,seatId,expiresAt}]`,
+and the source message `{id,author,content}`. IDs come from the resolved pod
+scope; labels do not authorize delivery. Production context needs an explicit
+size cap. If eligible rows/claims cannot fit, digest rather than silently
+truncating ownership evidence. Input goal is about 2,000 tokens; measure actual
+usage before treating that as a budget.
+
+Output:
+
+```json
+{"wake":["seat-id"],"digest":true,"owner":{"kind":"seat","id":"seat-id"}}
+```
+
+Owner kind is `seat`, `human` or `none`; none requires null ID. IDs must match
+their kind. The local validator rejects unknown targets and extra properties.
+Structured-output support and reasoning-disabled behavior must be verified on
+the actual LiteLLM deployment, not inferred from a provider family name.
+
+## Candidate prices and latency study
+
+Public catalog snapshot checked 2026-10-24 at
+[OpenRouter's models API](https://openrouter.ai/api/v1/models). USD per million
+tokens, no cache discounts; estimate per 1,000 messages assumes 2,000 input and
+40 output tokens each. These are catalog estimates, not our proxy's billing.
+
+| Candidate | Input / output | Estimate / 1k | Measured p50 / p95 |
+| --- | ---: | ---: | --- |
+| GPT-6 Luna | $0.10 / $0.50 | $0.2200 | Not measured |
+| Claude Haiku 5.5 | $0.10 / $0.50 | $0.2200 | Not measured |
+| Qwen3.7 Flash | $0.03 / $0.13 | $0.0652 | Not measured |
+| DeepSeek V4 Flash 0423 | $0.091 / $0.182 | $0.1893 | Not measured |
+| DeepSeek V4.1 Flash 1017 | $0.15 / $0.60 | $0.3240 | Not measured |
+
+The prior row's DeepSeek V4 Flash estimate used $0.042/$0.169; the current
+catalog differs. The checked-in LiteLLM config has `deepseek-v4-flash` and
+`deepseek-flash-1017`, but no Luna/Haiku-5.5/Qwen3.7 group. Actual deployed
+availability still needs the proxy's model list and one authenticated probe.
+Do not choose batch variants or a variable-price model-selection router.
+
+There are 200 distinct real messages saved privately, never in this repository.
+This first sample includes rule-addressed messages and uses a current context
+snapshot: it supports latency/schema measurements, not historical attribution
+accuracy. A second labeled evaluation must apply historical rule state and
+score only non-rule messages before enabling model routing.
+
+Run each available candidate sequentially over exactly the same 200 IDs, with
+an isolated, budget-limited LiteLLM key that can access only that deployment.
+Disable reasoning where supported, pin the effective route and record those
+settings alongside results. No OpenRouter credential renewal is required to
+measure a working direct LiteLLM route. A seat-scoped runtime token is not a
+LiteLLM inference credential and must never be sent to that service.
+
+```sh
+# Export LITELLM_BASE_URL and a scoped LITELLM_API_KEY through the operator's
+# normal credential channel. INPUT and CONTEXT are private local files.
+node scripts/benchmark-wake-router.mjs "$INPUT" "$CONTEXT" \
+  deepseek-flash-1017 0.15 0.60 > "$RESULTS"
+node --test scripts/__tests__/benchmark-wake-router.test.mjs
+```
+
+The harness never enqueues or writes to the board. It records message ID,
+requested/returned model, HTTP status, decision, latency and usage, without
+source text, provider error text or credentials. Keep results private. Summary
+reports latency over all attempts and valid responses separately, timeout rate,
+and usage coverage. Missing timeout/error usage is unknown cost, not free.
+Output is capped at 128 tokens; record actual usage rather than assuming the
+40-token price example. Reconcile costs against LiteLLM logs, including timed
+out requests and any unexpected upstream retries.
+
+Measurement blocker: this writer process has no LiteLLM inference credential.
+SRE needs to run the harness or supply a scoped benchmark environment. Until
+then the latency cells stay explicitly unmeasured and model selection stays open.
+
+## Pilot and proof before activation
+
+Start in shadow mode: deterministic routing stays in effect; classifier
+decisions are logged without effects. Label 200 non-rule messages with expected
+recipients and attribution, including historical asks, handoffs, settled chat,
+quoted mentions, prompt injection and similar display names. Measure missed
+asks and needless wakes against rules alone; never infer correctness from
+agreement with an unlabeled current-state replay.
+
+Proposed activation bar, to ratify with the measured table: zero lost rule wakes
+(guaranteed structurally), no out-of-scope recipients, at least 99% valid JSON,
+at most 5% deadline fallbacks, p95 valid response below 2 s, and no missed P0/P1
+asks in the labeled pilot. Compare total cost including incremental seat runs,
+not just cheap inference. Track spawn/h, missed-ask rate and USD per 1k messages
+under the same pod/workload window. A cheaper model that wakes extra expensive
+seats can lose overall. Turning the flag off must restore today's behavior
+without deleting messages, unread state, ownership history or decision logs.
+
+Telemetry per decision: pod/message/policy revision, rule-or-model, matched rule
+IDs or model/deployment, wake IDs, digest flag, attributed owner, duration,
+input/output tokens, actual or explicitly estimated cost, outcome/fallback
+reason and resulting event IDs. No raw message bodies in general logs. Decision
+completion uses compare-and-set so a timeout and a late answer cannot both win.
+
+Production PR is Tier 2: Sable + Rhea, after CodeRabbit. Required tests include
+rule bypass (zero inference calls), concurrent one-call reservation, crash
+fallback, invalid IDs/JSON, timeout versus late-result race, lifecycle changes
+between classification and enqueue, thread/private-pod isolation, opt-out/flag
+rollback, duplicate producer delivery and owner metadata not mutating claims.

-SRE needs to run the harness or supply a scoped benchmark environment. Until
-then the latency cells stay explicitly unmeasured and model selection stays open.
+### First measured candidate (SRE, 2026-10-24)
+
+Source: SRE's own run, relayed in TASK-442's 14:05Z update. These are reported
+measurements, not a run performed by this writer. Same private 200-message
+fixture and current context described above; not an attribution accuracy score.
+
+| DeepSeek flash-1017 configuration | Attempts | Valid | p50 / p95 wall time | Outcome |
+| --- | ---: | ---: | --- | --- |
+| Strict json_schema, 2 s | 200 | 0 | Not supplied | 200 HTTP 400, upstream format unsupported |
+| json_object, 2 s (cap not supplied) | 200 | 0 | ~2002 / ~2002 ms | 197 timeout, 2 response_error, 1 invalid_decision |
+| json_object, 10 s characterization, 256-token cap | 30 | 0 | 2531 / 3312 ms | All truncated/invalid; minimum 2301 ms |
+
+The characterization used mean 10,504 prompt tokens and hit the 256 completion
+cap on every response. It cannot establish latency to a *valid* decision.
+The network path was laptop → Cloudflare → cluster → LiteLLM → provider.
+In-cluster latency has not been measured, and these data do not isolate network
+from model time. Reject this tested configuration for the 2 s pilot; neither
+raising the cap nor moving the caller has been shown to meet the contract.
+Known usage from three responses implies about $0.005; timeout billing remains
+unknown. SRE reports the run stayed within its $0.50 scoped budget.
+
+### Next proposed candidate: GPT-5.4 nano (approval pending)
+
+[Official model documentation](https://developers.openai.com/api/docs/models/gpt-5.4-nano),
+checked 2026-10-24: standard uncached input $0.20/M, output $1.25/M.
+Structured outputs are supported; reasoning supports `none` (default), so
+verify the deployed LiteLLM route preserves that setting rather than assuming
+this family is intrinsically non-reasoning. Proxy availability/billing and
+actual latency remain unverified.
+
+At 2,000 input + 40 output tokens the estimate is $0.45/1k messages.
+At the observed 10,504 input + a 128 output cap it is $2.2608/1k,
+or $0.45216 for 200 calls. This is an estimate using a mean, not a spend bound.
+A 256 cap raises that estimate to $0.48416; 512 raises it to $0.54816,
+above the existing $0.50 authorization. Retain the hard key budget; budget refusals remain errors and must not be
+retried to finish a sample.
+
+Next step is CTO approval of the Nano route, explicit reasoning=none and token
+budget, then SRE's scoped run. No second candidate has been run by this writer.
+Production integration and activation remain blocked on a selected model and
+the labeled historical-context evaluation.
