 The existing target-uid config query already requires executing this same NODE before any F check, so a root-only executable mode that prevents the dropped uid running it fails preflight. No new root NODE execution is introduced.

+## Static review0186 and upstream drift
+
+Duckworth0186 statically approves164e16647/6887825e4, subject to green gate and log review. N1: M2 is the stand-in for the brief's diagnostic outer-bound mutant. It removes the shared legacy_run outer timer; its named killer runs only the precheck diagnostic in exec/hop with an independently guarded stalled supervisor, exact outer-timeout reason and bounded return. The fixed per-call production budget is also pinned by the inventory assertion. Keep the accepted M1-M15 scope. N2: M5 must die at the streams test because the wiring test reads runner text from source. N3: stderr disk growth retains the old talk.err risk; only root's tail read is bounded, with no new cap claim.

+Sage2898 publication: original branch6887825e4 pushed after range check. Drift48e450ce8..94c33a43c on five manifest paths is only31added DEFERRED lines, inserted into its gaps section; no deletion or source/test drift. UPSTREAM-DRIFT.diff/json retain it. Final integration must keep those entries and row276's appended closure; no integration or manifest rewrite has happened yet. No tests or Node ran.

++- **The case supervisor reports a fast child as an inner-session failure.**
++  (Row 253 N1, mos-1297 item 5.) A child that exits before the supervisor
++  verifies its session is reaped first, so the supervisor exits 85
++  (inner-session) instead of the child's own code. Mos measured rc85 in 39
++  of 40 fast-child bash runs. It fails closed, so it is not a 10-27 defect;
++  row 253 fixed only its own fixture (PYTHON_STUB execs python3). The
++  product fix is Vikunja 532, after 10-27. (2026-10-22)
++
++- **boardSend /api/seen returns 400 for a scan failure after writeMark.**
++  (Webby N2 on row 198, ruled sage-2867.) The mark is written, then the
++  rescan fails, and the client gets 400 as if its request were bad. Webby
++  suggests 500. It does not hold the 198 gate; binds the next row that
++  touches serve.mjs. (2026-10-22)

++- **Stale "row 203" text in the access command.** (Quackerjack, row 203
++  BUILD.md follow-up.) packages/cli/src/access.mjs lines 26-27, its help
++  string at line 36 and line 44, and packages/cli/README.md line 1107 say
++  peer homes stay unread "until row 203" adds the federation key. Row 203
++  changes only scripts/mosaic-config.mjs and test-config.sh, so once it
++  lands those lines point at a row that did not do the work. Binds the next
++  row that edits access.mjs. (2026-10-22)
++
++- **A remote outage can make the first library lookup outlast the tool
++  timeout.** (Row 224 residual, sage-2819.) In each 60 s window the first
++  lookup still runs an inline fetch, and that fetch can take longer than the
++  60 s tool timeout. Bound the inline fetch in a later row. (2026-10-22)
