Zetaris and Meterless

Zetaris: the evidence store every claim is checked against

Remove Zetaris and nothing can be marked verified.

Evidence store. When a file is read, the worker publishes its passages as JSON to a Zetaris FILESTORE table, hands Zetaris the file's PDF rendition, and keeps Zetaris's own PDFBox reading of it: a second extraction, independent of Konkyo's. A file is marked Ready only after Zetaris answers for it. (packages/zetaris/src/evidence.ts)
Pre-check that retrieved documents are present. (checks.ts)
Quote verification: every quote of an answer in one Spark SQL statement, a VALUES list joined to Zetaris's text. The same check covers the Analyst's matrix, study items, lecture notes and audio briefs.
Topic watches: each is a Lightning REST table over OpenAlex; new papers are found with one LEFT ANTI JOIN against the DOIs already seen. (watch.ts)

The engines are vendored unchanged (Apache-2.0) in packages/meterless and driven from packages/agents.

H-MEM (memory.ts): a 👎 with a reason, "wrong passage", or "this item is wrong" becomes a correction in your memory, with where it came from. The Planner reads relevant corrections before every answer; 👍/👎 adjust the confidence of the memories an answer used. Settings → Memory shows, edits and forgets them.
World Model (analyst.ts): each comparison is recorded as sources, claims and supports / contradicts / qualifies relations, each with the passage it was read from.
Markovian (scout.ts): deep search screens what it found in bounded steps that carry only the shortlist forward; its estimate of tokens saved is shown and logged.
