The scheduler rereads +the committed source at the entry's own pin and checks every span/hash; caller +text or a `verified` boolean is not proof. Only a successful explicit confirmation +creates an owner-labeled, signed case under `eval/knowledge-maintenance//cases/` +(or `KB_MAINTENANCE_CASES_DIR`). Dismissal appends a reason without creating a +case. `maintain status` includes owner-addressable observation IDs and outcomes, +including healthy `verified` observations. An owner may explicitly confirm a +healthy observation as an audit positive with `expected: verified`; its presence +alone creates neither a TODO nor a labeled case. Unlabeled candidates stay in service state and never become an oracle +automatically. + +For a correction calibration case, explicitly supply `calibration_kind` as +`correction` and a `correction_oracle` containing `expected_gate` (`pass`, `fail` +or `human`). A passing oracle also supplies `expected_page_sha256`: the hash of +the intended corrected page with its `updated` metadata normalized back to the +original value. The resolver preserves that owner-supplied oracle; it never +invents a corrected page or expected result. Calibration readiness requires audit +positive/negative cases and passing/rejecting correction oracles. + +## Consumer containment and rollout + +`KB_CONTAINMENT_CONSUMERS` is the JSON roster of actual consumer IDs; an upstream +slug is not automatically a consumer ID. The existing owner SSH publisher +installs signed policy through the public SDK installer and returns authenticated +ACKs. Public consumer config, signed policy, policy high-water state, issuance +registry and protocol latch live outside physical paired releases. Installation +and review publication share a lock, so an ACK confirms old-generation writes +have drained. Heartbeats run every 60 seconds; stale policy/ACK, invalid +signature, roster mismatch or replay fails closed after rollout is enabled. + +Direct records retrieval separately from context injection. Strict forwards its +provider-issued usage record. The shared final publication boundary checks +current availability under the installer lock. A hold retains the original +review and requests reassessment without publishing it or silently removing +claims that the model already consumed. Signed operational containment has its +own monotonic generation, independent of snapshot activation or pair rollback. + +Durable correction uses the governed owner rule's existing `retire`/`replace` +operations and quality gates. Installing a local active knowledge snapshot does +not update the provider packaged in the bot; deploy a verified provider/bot pair. +Deploy guards refuse a protocol older than the shared durable latch, including +automatic health-check rollback. Source defaults remain disabled. The explicit +activation sequence below enables the protocol with an empty signed decision +list before trial; automatic corrective holds/publication stay gated by trial, +calibration and authenticated consumer readiness. This document does not enable +a deployment or restart a service. + +## Authority, publisher and consumer configuration + +Use durable paths outside snapshot directories and physical provider/bot releases. +The authority runs in the existing lease-holding knowledge service, with its +existing protected service key. These example paths are deployment choices: + +```dotenv +KB_STATE_DIR=/srv/kb/shared/service +KB_SIGNING_KEY=/srv/kb/owner/service-private.pem +KB_PUBLISHER_PUBKEY=/srv/kb/owner/publisher-public.txt +KB_MAINTENANCE_ENABLED=1 +KB_MAINTENANCE_OWNER=knowledge-maintainer +KB_MAINTENANCE_OWNERS=actual-owner-login +KB_MAINTENANCE_MAX_UNITS=20 +KB_MAINTENANCE_CASES_DIR=/srv/kb/shared/maintenance-cases +KB_MAINTENANCE_REQUIRED_CHECKS=["suite"] +KB_CONTAINMENT_ENFORCE=1 +KB_CONTAINMENT_POLICY_DIR=/srv/kb/shared/containment-authority +KB_CONTAINMENT_CONSUMERS=["native","reviewbot-vllm-omni","reviewbot-vllm-gr"] +KB_CONTAINMENT_CONSUMER_ID=native +KB_CONTAINMENT_PUBLIC_KEY=/srv/kb/owner/service-public.txt +KB_CONTAINMENT_STATE_DIR=/srv/kb/shared/containment-native +KB_CONTAINMENT_RELEASE_FILE=/opt/infermatrix-release/manifest.json +``` + +Also set `KB_MAINTENANCE_COSTS` to a JSON object keyed by the exact configured +generator/judge labels. For example, a service using the current default role +labels could explicitly account each subscription call at an owner-approved +allowance: + +```json +{ + "claude-code:claude-opus-5-5": {"kind":"subscription","accounted_usd":0.5}, + "codex:gpt-6-sol:medium": {"kind":"subscription","accounted_usd":0.5} +} +``` + +This example is not provider pricing. Use the actual role labels and approved +accounting amounts; an absent entry blocks dispatch. Required CI names likewise +must match the repository's real checks. + +The native SDK configuration above uses the authority's signed `policy.json`, +its pinned service public key and a separate durable consumer state directory. +Alternatively, `KB_CONTAINMENT_CONFIG` may supply the complete SDK JSON object +with `enabled`, `policy_path`, `public_keys`, `state_dir` and `consumer_id`. +Do not mix a different explicit config into requests. Use an actual regular +release manifest at `KB_CONTAINMENT_RELEASE_FILE`; the running scheduler hashes +its bytes and proves readiness under its own live lease. Without that file the +SDK falls back to loaded implementation/version hashes, which must be visible +as such in the operator's release inventory. Native readiness is produced by +`native_ack(rt)` on scheduler ticks, not by creating a JSON ACK by hand. + +Each bot instance has its own existing `REVIEWBOT_STATE_DIR` and explicit consumer +identity. For example, the Omni instance uses: + +```dotenv +KNOWLEDGE_MAINTENANCE_ENABLED=true +KNOWLEDGE_MAINTENANCE_CONSUMER_ID=reviewbot-vllm-omni +KNOWLEDGE_MAINTENANCE_POLICY_PATH=/srv/reviewbot/shared/state/knowledge-maintenance/policy.json +KNOWLEDGE_MAINTENANCE_STATE_DIR=/srv/reviewbot/shared/state/knowledge-maintenance +KNOWLEDGE_MAINTENANCE_PUBLIC_KEYS_FILE=/srv/reviewbot/owner/service-public-keys.json +``` + +The key file is a JSON list of public `ed25519 BASE64` strings. The GR instance +uses `reviewbot-vllm-gr` and its own shared state directory. Preserve the physical +paired release's existing `REVIEWBOT_RELEASE_MANIFEST`. Prepare each exact SDK +config with `omni-reviewbot knowledge-maintenance-config`; the generated +owner-only `config.json` is the publisher's `config_file`. A running watcher +refreshes it and writes `heartbeat.json` every 60 seconds. Readiness binds its +consumer, accepted generation/digest, protocol, actual manifest bytes and exact +config digest. Missing, stopped/stale, mismatched or disabled instances cannot +satisfy the runtime ACK barrier. A recently stopped watcher can retain readiness +only within the remaining heartbeat freshness window. + +The existing owner publisher retains `KB_SERVICE_PUBKEY`, `KB_PUBLISHER_KEY` +and `KB_PUBLISHER_GIT_AUTHOR`. Set `KB_CONTAINMENT_TARGETS_JSON` to the exact +owner SSH targets, for example: + +```json +{ + "reviewbot-vllm-omni": { + "host":"owner@review-host", + "python":"/srv/reviewbot/current/.venv/bin/python", + "config_file":"/srv/reviewbot/shared/state/knowledge-maintenance/config.json", + "release_file":"/srv/reviewbot/current/manifest.json" + }, + "reviewbot-vllm-gr": { + "host":"owner@review-host", + "python":"/srv/reviewbot/current/.venv/bin/python", + "config_file":"/srv/reviewbot/shared/state-vllm-gr/knowledge-maintenance/config.json", + "release_file":"/srv/reviewbot/current/manifest.json" + } +} +``` + +Every target has exactly `host`, `python`, `config_file` and `release_file`; +all paths are absolute. The interpreter must belong to the actual deployed +pair. Native is acknowledged locally by the running lease owner, so it needs +no duplicate bot SSH target. The publisher installs through the SDK fence, +waits for a matching heartbeat less than 180 seconds old and returns only +publisher-signed authenticated SSH metadata. It refreshes independently of +paid publishing work. A changed generation can therefore install successfully +while readiness stays pending until the next real heartbeat. Arbitrary JSON +or an installer-only receipt cannot satisfy this barrier. +The 180-second runtime window covers the watcher, publisher and service hops; +the signed policy still expires after 10 minutes, and merge authorizations have +their own shorter lifetime. Native protocol heartbeats run independently of paid +audit work while their separate ledger connection verifies the actual lease. + +## Activation sequence + +1. Deploy the reviewed protocol-capable provider and bot pair with source defaults + disabled. Use a real merged provider SHA; do not pin an uncommitted change. + Verify both physical release identities and preserve shared state on rollback. +2. Prepare the explicit roster, public trust, durable paths and authenticated + transport. Start the signed protocol with an **empty decision list**, without + enabling automatic maintenance corrections. Enable each actual consumer's + SDK protocol configuration, prepare its owner config and verify real native + and bot runtime ACKs. `kb serve` refreshes the authority's signed list; do not + copy policy files around the installer fence or hand-create readiness files. +3. Enable the bounded nightly audit lane, retaining the configured lifecycle + modes and shadow correction behavior during the trial. Verify source-pinned + `unknown` behavior, explicit accounting, fair coverage, protected-entry owner + routing and preservation of original outcomes. Install no live corrective + holds on the strength of an uncalibrated trial finding. +4. Accumulate at least **seven consecutive effective actual nightly cycles**. + Each cycle must include a real definitive original-source semantic review + for **every eligible public repository**, under the same bound policy and + frozen denominator. Empty/no-op runs, missing evidence, execution errors, + budget-limited nights, manual requests and fabricated/backfilled dates do not + count. No command can substitute seven immediate requests for seven nights. +5. Explicitly confirm real defect findings and healthy verified observation IDs + with original-source evidence to build the + audit positive/negative and correction passing/rejecting human corpus. Queue + calibration and an isolated real-SDK revocation drill using distinct stable + request IDs. Confirm current calibration, current roster ACKs and drill + evidence; the isolated drill does not revoke any production knowledge. +6. Review the deployment configuration in a PR and explicitly authorize the + relevant existing `auto_merge` lifecycle scope. The service never flips a + repository's mode because a trial passes. Only the already configured + publishing scope can proceed once all readiness requirements hold. A real + correction then follows hold propagation, normal gates, exact reviewed head + and CI, merge, active-byte verification and authenticated restoration ACKs. + +Keep source updates, semantic audit coverage, proposed corrections, real merged +and active bytes, and consumer propagation visible separately in `maintain status`. +An unregistered reader is outside isolation coverage. A policy or implementation +change invalidates readiness for the previous policy; failed owner requests are +retained and routed for follow-up rather than counted as successful nights. diff --git a/eval/knowledge-maintenance/README.md b/eval/knowledge-maintenance/README.md new file mode 100644 index 00000000..c30d1185 --- /dev/null +++ b/eval/knowledge-maintenance/README.md @@ -0,0 +1,33 @@ +# Human-confirmed maintenance calibration + +This directory holds signed evaluation cases, outside served knowledge. +Cases live at `/cases/.json`.
