+bounded Vallm review round. The review runs deterministic complexity and
+security checks, attempts Vallm syntax analysis, and uses an OpenRouter
+semantic judge supplied by the existing organization-level
+`OPENROUTER_API_KEY` secret.
+
+The semantic judge is `google/gemini-3.1-pro-preview`, selected from the current
+live `llm-code-benchmark/v1` report because it is the only compared model that
+qualified for both repair and validation (repair 1.000, validation 0.929,
+security 1.000 and availability 100%). Vallm's Python-oriented `--regression`
+mode is intentionally not used for TypeScript: the separate required `verify`
+job owns TypeScript compilation and the repository's 335-test regression
+suite. Koru remains the read-only semantic, complexity and security review
+boundary. Vallm still attempts syntax analysis, but 0.1.94 passes the uppercase
+language enum `TYPESCRIPT` to a parser that accepts lowercase `typescript`.
+The workflow now applies a pinned lowercase compatibility boundary before
+parsing and still blocks if any `syntax.unsupported` finding remains.
+
+The repaired execution budget is explicit and layered. GitHub terminates the
+whole job after 10 minutes; Vallm and its LiteLLM request are bounded to 420
+seconds so report construction, artifact upload and attestation retain roughly
+three minutes of the job budget after an active-review timeout (less the setup
+time already consumed). Responses are capped at 8192 tokens. LiteLLM retries are
+disabled, therefore provider HTTP errors such as 401, 402, 403 or 404 fail
+immediately rather than consuming the timeout. A pinned compatibility boundary
+lowercases Vallm 0.1.94's language ID before tree-sitter parsing. Semantic
+`info` and `warning` findings remain in the attested report as advisory when
+Vallm's file-level verdict is `pass`; semantic errors and every syntax,
+complexity, security, provider, malformed/missing-result or timeout finding
+remain blocking.

   No credential value appears in the workflow output.
+- Pull request #3 exposed that the original Koru configuration had drifted from
+  the current benchmark winner. Run `30712589077` still used
+  `openrouter/deepseek/deepseek-v4-pro`; Vallm also attempted `pytest` for the
+  TypeScript diff and the semantic request failed with OpenRouter 401 `User not
+  found`. The workflow now uses the qualified Gemini model and delegates
+  regression to the already passing required `verify` job. The 401 cannot be
+  repaired in repository code: a trusted repository or organization owner must
+  rotate the `OPENROUTER_API_KEY` Actions secret and rerun the exact commit.
+- Pull request #4 run `30712853708` passed the read-only Koru gate for commit
+  `a4eb0f9`. Its attested `t2c.koru-code-review/v1` report records
+  `openrouter/google/gemini-3.1-pro-preview` and an empty supported-source set,
+  so no provider request or cost occurred. This proves the deployed workflow
+  configuration and no-source path; it does not supersede the required live
+  rerun after secret rotation.
+- Workflow dispatch `30713017811` then exercised that workflow against the
+  exact two-file TypeScript diff from pull request #3. The report records the
+  Gemini judge and no longer contains a regression/`pytest` error. It rejects
+  fail-closed because OpenRouter still returns 401 `User not found`; it also
+  retains Vallm 0.1.94's `TYPESCRIPT` parser warning. Report construction,
+  artifact upload and provenance attestation passed. AC-21 therefore remains
+  open until the secret is rotated and the upstream parser defect is fixed or
+  replaced with equivalent deterministic Koru-job evidence.
+- The user subsequently authorized repository-secret rotation. A fresh
+  repository-level `OPENROUTER_API_KEY` was written through `gh` stdin on
+  2026-08-01 without exposing its value; it takes precedence over the stale
+  organization secret only for `semcod/todo2code`. Dispatch `30714664770`
+  proves the credential and increased provider limit now work: Gemini reviewed
+  both TypeScript files with no provider error. Both file-level verdicts are
+  `pass`, but Koru correctly remains non-passing under the current fail-on-any-
+  finding policy because Vallm emits its known uppercase-language parser
+  warning plus advisory whole-file findings unrelated to the model-default
+  diff. The remaining AC-21 blockers are review context/parser policy, not the
+  GitHub credential.
+- The timeout/policy repair bounds the complete job to 10 minutes and the
+  active review to 420 seconds, caps output at 8192 tokens, disables retries
+  (including 404), normalizes the Vallm TypeScript language ID and separates
+  advisory semantic warnings from blocking deterministic/provider/semantic
+  errors without removing any finding from the attested JSON.
+- Repaired workflow dispatch `30746421293` reviewed the exact pull request #3
+  range `2e87205..6b79527` with Gemini in 1 minute 24 seconds. Its attested
+  report selects `src/config/env.ts` and `test/config-env.test.ts`, records 2/2
+  passed, no failed files, no parser/provider finding and exit 0. All five
+  whole-file semantic observations remain visible as advisory; the policy
+  records Vallm's original exit 2 before deterministic normalization.
+- A follow-up exact-stack LiteLLM probe used a local HTTP endpoint: HTTP 404
+  produced `NotFoundError` after about 705 ms with exactly one request and the
+  8192-token ceiling intact. A slow endpoint with a 0.5-second probe ceiling
+  produced `Timeout` after about 799 ms with exactly one request. Fresh local
+  `npm run verify` and Docker `e2e-core` pass; Docker `e2e-full` still stops at
+  the separately attributed stale Rust lock with `cargo fetch --locked` exit
+  101, without any ticket-018 change to the SDK.
