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 context 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.
