Done

• Integration: hash engine + parity lane A (core) + lane B (UI) merged to xattr main; type clashes resolved (XattrIndex owns STATUS-API/VerificationBadge; UI refs renamed); a fixture fallback that showed invented numbers removed. FEAT-20260927-21/-22/-14 resolved; TASK-20260925-04 superseded.
• X-D10 credential boundary (PRD v2 §9.2): credential-shaped files are listed but never opened, hashed or matched; credential stores never walked; MCP returns them only as listing rows; xattrctl credential-candidates (XEntropy contract v1) and credential-purge. Real store: 959 candidates, 531 hashes + 111 snippets purged. ReplicantDB's own copy routed to its owner as SEC-20260928-01.
• UI on the real store (W1), house standards 12 → 3 FAIL then 0 of the 3 left in code (W3), App Intents with a Metadata.appintents build gate (W6), G3 classifier + G5 query parser — harness 12/13 (W2), FSEvents change feed xattrd --watch (W4: ~2 s event→visible, 14/46 MB RSS), classification in the scan cycle.
• Fixes: store unreadable after another tool's clean close (ISSUE-20260927-51); load-starved tests (ISSUE-20260927-44); build.sh hid a failing target; dead Settings toggles that implied invariants could be turned off; inspector hijacking the window title; review queue proposing document_class as a tag; status --summary.
• Real store on rdmsm4x → schema v2 (84 s; all counts equal; 1,000-row sample identical; clone backup kept).
• Releases: build 8 and build 9 (0.9.0) on all six Macs, notarized (b1ba4f96), stapled, DR unchanged, running on both Intel hosts. Tests 238 (163 + 25 + 50) on arm64 and x86_64.
• Phase 2 step 1: own xattr store on all six hosts (imports 00:24-00:49: rdmpw3265m 1,227,770 · rdmpw3275m 507,761 · rdmbair13m5 62,035 · rdmbair15m5 59,764 · jdmbair13m5 1,560 rows; X-D10 purge on each; read-only on ReplicantDB).
• Watch soak: live governor pause on rdmsm4x (1.9 MB paused); threshold now scales with cores (deea65b, next build). Real-tree latency after the first catch-up scan still to measure.
• Product spec regenerated and published: dev.ecs0.net wiki/xattr.html, eastcoastscience.net (Pages c9ac73d9), rdmbair15m5 Desktop + opened in Chrome. Three target-UI proposals (A/B/C) for Rich to bless; recommendation A.
• SPIKE G11 Mac↔︎Mac answered: #S xattrs sync up to 20 KiB per attribute; 24 KiB+ silently dropped.

For Rich (one line each)

• Bless a target UI: reply A, B or C (spec page, "Target UI options").
• DEC-20260928-01: keep the permissive MCP default (A, recommended) or default-deny agents (B).
• SPIKE-20260925-01: 5 minutes on the iPhone (steps in apps/xattr/docs/SPIKE-G11-ICLOUD-XATTR.md).
