Production collection emits exactly one wrapper-owned + `## codegraph explore` provenance marker and treats any raw stdout line that + contains the same marker text as marker-contaminated input: that whole line + is discarded before the trusted section is retained. Clean semantic lines + from the same output remain eligible. If raw stdout contains only marker- + contaminated lines, collection retains an empty labelled explore section + rather than letting a neutralization annotation become semantic evidence. A + strict manifest with more than one trusted explore marker is therefore + ambiguous and fails closed. Initialization/status banners, an empty labelled + explore section, unlabelled concatenated output, an explicit `No relevant + code found` semantic response prefix after known lifecycle/wrapper + annotations are removed (including irregular ASCII or Unicode whitespace), + truncation/workflow-command annotations without retained semantic bytes, and + control/punctuation-only output are not semantic review evidence. The same + words appearing later inside retained source/code context do not erase + independent semantic evidence. Setup/status bytes cannot redefine the + wrapper-owned explore boundary. When the standard changed-file explore query + returns an explicit empty result, the collector may probe the pinned + CodeGraph `node --file … --symbols-only` interface only for exact current-head + regular files whose repository-relative path can be walked from the checkout + without traversing any symlinked component. The checkout root itself must be + a physical directory whose resolved path equals its absolute path; a symlinked + checkout root or symlinked ancestor invalidates symbol recovery. A regular + file reached through a symlinked parent is not current-head evidence and + cannot seed recovery. The collector caps the structural maps and serializes + each recovered `{path,symbols}` pair as canonical JSON marked explicitly as + untrusted retrieval data before one second `explore`; neither Git filename + bytes nor repository-derived symbol text is reinserted as raw prompt + instructions. Known leading CodeGraph lifecycle/status banners are removed + only for this empty-result classification, so a banner cannot suppress + symbol-seeded recovery while arbitrary preceding output still cannot trigger + a repository probe. The primary explore query preserves each selected changed + path in full instead of truncating individual path identities; it admits at + most 80 changed files and 24,079 aggregate characters. The manifest retains + bounded current-head file content for every selected file through that same + 80-file canonical scope; above 80 files both semantic scope and changed-file + context fail closed rather than reviewing a historical 12-file prefix. + Exceeding either exact-scope budget fails closed instead of querying a prefix. + The changed-file recovery scope removes only Noema's single query-delimiter + space and otherwise preserves filename whitespace bytes exactly, including + tabs, newlines, repeated spaces, and leading/trailing spaces. Symbol-recovery + segmentation likewise preserves the full filesystem-valid path instead of + imposing a separate per-path character cutoff. To keep ambiguous whitespace + parsing bounded, recovery admits at most 512 whitespace tokens and 4,096 + candidate filesystem probes; exhausting either budget fails closed without + issuing a symbol query. Recovery is complete rather than sampled: if the + uniquely recovered changed-file scope contains more than eight files, Noema + does not take an eight-file prefix and retry. The original empty result + remains fail closed until the full selected scope can be represented within + the seed bound. Where literal spaces could be either filename bytes or inter- + path separators, symbol recovery still requires exactly one filesystem-valid + segmentation; multiple valid segmentations fail closed instead of letting an + unchanged lookalike path become a retrieval seed. The node output never + counts as review evidence by itself; deleted, unresolved, symlinked-component, + unindexed, or symbol-less paths leave the original empty result fail closed. + The local host-process CodeGraph fallback also builds a closed execution + environment instead of copying the parent environment: only `PATH` and locale + discovery variables may be propagated; `HOME`, `TEMP`, `TMP`, and `TMPDIR` + are replaced by one fresh per-command private temporary directory and + `NO_COLOR=1` is set explicitly. Process injection, host user configuration/ + credentials, ambient temporary-directory capabilities, credential-helper/ + socket, container/Kubernetes, proxy, arbitrary workflow, and provider + variables such as `NODE_OPTIONS`, `GIT_ASKPASS`, `SSH_AUTH_SOCK`, + `DOCKER_CONFIG`, `KUBECONFIG`, and `HTTPS_PROXY` are not ambient CodeGraph + authority. Production central review still uses the separately attested no- + network sandbox; this host fallback does not replace that isolation boundary. + The production `DockerCodeGraphRunner` now owns the same semantic wrapper and + passes both the exact symbol probe and any symbol-seeded second `explore` + through its verified no-network container boundary. It extracts only the + trusted sandbox copy receipt and sole explore stdout section before semantic + classification, so setup/status bytes cannot satisfy the strict gate and an + empty production explore cannot silently fall back to a host CodeGraph + process. 2. **MEDIUM-or-higher dependency findings can't ride out on an approve.** An unresolved OSV/Trivy/dependency-review finding at MEDIUM+ downgrades an approval to `request_changes` with the finding attached — the org rule is @@ -44,10 +116,14 @@ they hold regardless of what the model says: 3. **Current-head failures remain blocking.** Failed GitHub Checks and MEDIUM-or-higher code-scanning/SARIF alerts deterministically downgrade an approval and retain their exact job, rule, path, and bounded log evidence. -4. **Reviewer independence cannot deadlock.** The exact primary check name - `opencode-review` is ignored by Noema's deterministic failed-check gate; all - other failed checks and unresolved non-outdated inline threads remain - blocking. +4. **Reviewer independence cannot deadlock.** The exact reviewer check names + `noema-review` and `opencode-review`, plus the downstream + `metadata-only gate evaluation`, are excluded from Noema's deterministic + failed-check gate because they cannot be prerequisites for the review that + produces them.
