+# Nightly SOTA research agent
+
+`nightly-sota-agent.yml` turns recent public research into at most one
+repository issue and, for low-risk topics, one draft offline-prototype pull
+request. It is intentionally not a general-purpose autonomous coding agent.
+
+## Enablement
+
+The committed schedule is `03:17 UTC` every day. Scheduled runs stay disabled
+until both repository settings exist:
+
+1. Actions secret `COGNITUM_NIGHTLY_API_KEY`, issued with only the Cognitum
+   `completions:mid` scope.
+2. Actions variable `RUVIEW_NIGHTLY_SOTA_ENABLED=true`.
+
+The key must not receive guidance-write, evolve, pods, brain, Flywheel-write,
+or administrative scopes. First run the workflow manually in `dry-run` mode;
+that mode only collects a bounded evidence artifact and never reads the secret
+or writes an issue. Manual `live` mode is restricted to the repository owner.
+
+The repository must also allow GitHub Actions to create pull requests. Normal
+branch protection must require at least one approving review and the
+`Verify contributor harness` status check. The publisher requires that exact
+job-name check to be bound to the GitHub Actions app,
+uses GitHub's effective-active-rules endpoint, and stops before prototype
+generation when either requirement is absent. It does not request an
+administrative token to inspect hidden ruleset bypass actors; safety does not
+depend on that metadata because the publisher has no merge or `main`-push path.
+
+## Authority split
+
+| Job | External credential | Repository authority | Result |
+|---|---|---|---|
+| `collect` | none | contents read | Normalized public Cognitum registry and recent arXiv evidence |
+| `propose` | Cognitum completions key | contents read | One schema-checked proposal |
+| `score` | none | contents read | Frozen Darwin digest, completeness score, honest-null Flywheel replay |
+| `issue` | GitHub token | issue write, PR read | One deduplicated issue |
+| `implement` | Cognitum completions key | contents read | Declarative transform and test vectors |
+| `validate` | none | contents read | Schema, template, syntax, claim, path, digest, and replay checks |
+| `publish` | GitHub token | branch/issue/draft-PR/Actions write | One draft PR and an explicit read-only harness-verifier dispatch |
+
+The Cognitum key and a write-capable GitHub token never coexist in one job.
+Model output is never executable code. Repository-owned templates emit the
+prototype module and tests, which this workflow syntax-checks but never runs.
+
+## Hard boundaries
+
+- Public HTTPS sources are fixed to the Cognitum application registry and the
+  arXiv Atom API. Redirects, oversized responses, unexpected media types, and
+  schema drift fail closed.
+- Retrieved text is `CLAIMED`, untrusted evidence. It is quoted inside a fixed
+  trusted prompt and cannot grant authority.
+- The Darwin genome is read-only. Scheduled jobs never invoke Darwin evolution.
+- Flywheel runs a separate committed honest-null canary. A valid canary stays
+  root-only, rejects its candidate, and reports zero verified improvements and
+  no promotion. It does not evaluate the nightly proposal. The workflow's
+  static authority split and artifact gates are what prevent nightly learning
+  or promotion.
+- High-risk topics stop at an issue. This includes production, security,
+  authentication, release/deployment, workflows, dependencies, firmware,
+  hardware, networking, native plugins, HomeKit pairing, and voice protocols.
+- Low-risk model output is a closed transform DSL: bounded scalar test vectors
+  and 1-8 allowlisted operations (`center`, `normalize-peak`, `absolute`,
+  `square`, `difference`, `moving-average`, or `clip`). Local trusted templates
+  emit exactly five `.md`, `.json`, and `.mjs` files below
+  `examples/research-sota/nightly/<fingerprint>/`. Existing files, symlinked
+  parents, dependencies, binaries, executable modes, and more than 400 lines
+  are rejected.
+- Publication is a draft PR. The agent cannot approve, merge, release, promote,
+  or modify the reviewed shared brain.
+
+## Deduplication and failure behavior
+
+The stable fingerprint hashes sorted evidence IDs, finding class, and subsystem.
+Issues and PRs carry an exact hidden marker. Only markers on
+`github-actions[bot]` records with the automation label are trusted for
+deduplication, so copied issue text cannot suppress future runs.
+
+A failure leaves the last completed bounded artifact for seven days. Model,
+protection-preflight, or validation failures may leave an issue without a PR;
+maintainers can inspect the run and decide whether to continue manually. The
+workflow does not retry a failed model call, force-push a branch, close an
+issue, or delete a branch.

+# ADR-284: Bounded nightly SOTA research agent
+
+| Field | Value |
+|---|---|
+| Status | Accepted - implementation gated off by default |
+| Date | 2026-07-29 |
+| Builds on | ADR-283 |
+
+## Context
+
+RuView needs a repeatable way to notice relevant state-of-the-art work and turn
+it into reviewable repository activity. A nightly model with simultaneous
+network, repository-write, policy-evolution, and execution authority would
+create an unacceptable prompt-injection and supply-chain boundary. It could
+also confuse generated confidence with scientific evidence or silently turn a
+research suggestion into production code.
+
+Cognitum exposes an OpenAI-compatible completion service and a public
+application registry. The contributor harness already commits a Darwin genome
+and a signed Flywheel replay gate. Those components can support nightly
+research without granting unattended learning promotion.
+
+## Decision
+
+Add a scheduled GitHub Actions workflow that runs daily at `03:17 UTC`, remains
+disabled until a maintainer enables a repository variable, and supports a
+manual evidence-only dry run.
+
+The live flow has seven jobs:
+
+1. Collect bounded public Cognitum-registry and recent arXiv evidence.
+2. Ask Cognitum `cognitum-mid` for one proposal that is locally validated
+   against a strict schema.
+3. Score proposal completeness using the frozen Darwin policy and verify an
+   honest-null Flywheel replay.
+4. Deduplicate or create one issue.
+5. For a locally classified low-risk proposal only, ask Cognitum for a tiny
+   declarative transform and bounded test vectors. Trusted repository templates
+   turn that data into the prototype module, tests, JSON, and README.
+6. In a job with no external secret or GitHub write token, revalidate every
+   artifact, verify the Flywheel replay, and perform static and syntax checks
+   without executing generated code.
+7. In a job with no model credential, re-hash the validated artifacts, create a
+   new branch, open one draft PR, link it to the issue, and explicitly dispatch
+   the credential-free contributor-harness verifier.
+
+The jobs exchange bounded JSON artifacts. Cognitum receipts retain the
+provider, endpoint, exact resolved tier/model, request ID, a recomputable
+routing attestation, and digest metadata. Credential-free validation rebuilds
+the deterministic request and verifies its digest. The raw-output digest is
+audit metadata only because raw model transcripts are not retained.
+
+## Security and evidence policy
+
+Retrieved titles, abstracts, descriptions, and links are untrusted `CLAIMED`
+evidence. Source hosts, paths, media types, redirects, time, byte counts,
+records, and citations are validated. The fixed trusted prompt states that
+evidence has no instruction authority. Model output is parsed as one JSON
+object and locally reconstructs risk, citations, implementation disposition,
+and fingerprint.
+
+Risk classification is deliberately conservative. Security, authentication,
+cryptography, workflow, dependency, release, deployment, production, firmware,
+hardware, network-server, native/Wasmtime plugin, HomeKit pairing, STT/TTS, and
+satellite-voice proposals are issue-only.
+
+Autonomous implementation is restricted to new files beneath a fingerprinted
+`examples/research-sota/nightly/` directory. The model cannot supply paths or
+source text. It selects only a schema-bounded scalar transform and matching
+test vectors; repository-owned templates deterministically emit exactly five
+files. It cannot edit existing files or add dependencies. File count, size,
+line count, paths, symlink ancestry, numeric bounds, operation schema,
+secret-shaped values, canonical template digests, and accuracy claims are
+checked. Emitted source receives syntax checking, but is not executed.
+
+The deterministic score is named `PROPOSAL_COMPLETENESS`. It is explicitly not
+a novelty, scientific-quality, safety, or performance score.
+
+## Darwin and Flywheel boundary
+
+Nightly automation reads the committed Darwin genome as frozen prompt policy.
+It never calls Darwin evolution or any Cognitum evolve, pod, guidance-mutation,
+brain-write, or promotion endpoint.
+
+Flywheel evaluates the unchanged policy with the repository's honest-null
+fixture. The signed replay must verify, report zero verified improvements, and
+report no promotion. This canary proves only that the committed Flywheel gate
+stayed root-only, rejected its candidate, and did not promote under the frozen
+fixture. It does not evaluate the proposal. The no-learning/no-promotion
+boundary for the nightly run comes from the workflow's static authority split,
+closed commands, and artifact validation.
+
+## Credentials and publication
+
+Scheduled enablement requires:
+
+- repository secret `COGNITUM_NIGHTLY_API_KEY`, limited to
+  `completions:mid`; and
+- repository variable `RUVIEW_NIGHTLY_SOTA_ENABLED=true`.
+
+Model jobs receive no write-capable GitHub token. GitHub mutation jobs receive
+no model key. Validation receives neither. The publish job has the additional
+`actions:write` permission solely to dispatch the read-only
+`ruview-harness-flywheel.yml` verifier with Darwin disabled, because a PR
+created by the workflow token may not trigger ordinary pull-request workflows.
+
+The agent creates draft PRs only. It cannot approve, merge, release, promote a
+Darwin candidate, or update canonical shared-brain records. Before any branch
+write, it re-fetches the issue and repository rules. Publication requires the
+issue to remain open, bot-authored, correctly labelled, and fingerprint-bound;
+`main` must require at least one approving review and the
+`Verify contributor harness` job-name check. The publisher requires that exact
+check name and GitHub Actions integration ID from GitHub's
+effective-active-rules endpoint. GitHub hides
+ruleset bypass actors from read-only tokens, so the workflow is not given an
+administrative token to inspect them. Its safety does not depend on that
+metadata: the publisher can create only a non-default branch and draft PR and
+contains no merge, approval, or `main`-push path. Branch protection and
+maintainer review remain the authority boundary.
+
+## Consequences
+
+RuView gains a low-volume research flywheel with durable evidence, stable
+deduplication, and inspectable failure artifacts. A compromised paper,
+registry record, or model can at worst propose bounded new example files that
+still require static gates and human review.
+
+The tradeoff is intentionally limited autonomy: production ideas become issues,
+generated prototypes are not executed, and a missing credential, service
+outage, schema drift, or validation ambiguity stops the run rather than
+guessing. Maintainers must explicitly enable the schedule and permit Actions to
+create pull requests.
