 2026-11-06 UTC | #797 stall-guard review fix round | Before: managed stdout added or omitted bytes relative to adapter text mode, a signalled child lost its exit-137/stderr receipt, and no-route incurred the instance-running cooldown. After: adapter-specific byte rendering, a fixed signal-name diagnostic and signal exit status, and a 30-second cooldown only for instance-running; no-route can be retried after the route is set. New regression controls fail on 3e754c96a; real local-API adapter comparisons and owned-child death receipts match base behavior. Node 26 harness rerun 270/270; CLI whole-file coverage 1,197 pass and one existing federation skip after two whole-file reruns (one known timing flake and one interim stdout-fallback regression, both rerun green); isolated release 251/251 and gate-lane 61/61. The managed-session copies pass 20/20; all six real guard scenarios pass. Bus project-files independently reproduces the reviewed base hang under an external timeout. Initial namespace-only project-files attempt hit interpreter-unsafe; corrected ordinary-user run retained. Queue refused linked worktree; no push, deploy, model calls, live host, secret, policy, role, contract or schema changes. Exact evidence and remaining review boundary: /mnt/storage/scratch/mosaic-lead/mvp3/stall-guard-r2-report.md.
 
 2026-11-06 UTC | #797 stall-guard integration merge | Before: stall-guard tip 6b2c925b9 and integration 5255e4e74 each supplied a Claude activity route; managed Pi also had two potential marker producers. After: BASE's Claude stream helper is authoritative, the Pi monitor is retained and its extension duplicate is disabled for managed turns, runner metadata suppression and newline filtering coexist, instance-running-only cooldown remains, and known/unknown child-signal receipts survive on both paths. Claude empty-delta handling follows BASE's selected helper; helper SHA pin updated. Node 26 final harness 309 pass, CLI main/lane/release 885/61/251 pass with one FED R7 skip, separately verified guard E2Es 11 pass, bus excluding project-files 1615 pass. Bus project-files had 5 pass then timeout/cancellation on both candidate and exact BASE; gate is not green. One earlier harness run failed the known Claude row-66 timing assertion (exact BASE full harness 277/277 and two file runs 14/14; older-base reproduction recorded by prior review); final rerun passed. An initial signal test invoked the removed Claude monitor and was adapted. Queue refused linked worktree; canonical queue read returned nothing. Local merge candidate only, no push or deployment. Full counts, caveats and evidence: /mnt/storage/scratch/mosaic-lead/mvp3/stall-guard-int-report.md and stall-guard-int-evidence/.
+2026-11-06 UTC | #797 supervisor schema guard implementation | Before: the 3s-only accounting guard refused the 3t archive store. After: the lead-authorized closed 3s/3t fallback preserves 3s compatibility and accepts 3t; store.mjs performs load-time file reads and in-memory schema/migration execution, so it is not imported into the supervisor. The real-Store current-version regression failed on BASE with test-store-schema-refused; synthetic 3s accepts, 3r/3u/missing refuse. DDL diff adds only project_archives objects. README documents owner diagnosis and restoration or campaign end without reset. Sequential Node 26 whole-file gates: budget 102/0, isolated identity 8/0, browser 13/0, lifecycle 2/0; no skips. Evidence: /mnt/storage/scratch/mosaic-lead/mvp3/supervisor-3t-evidence/; local candidate for independent review, no push or deployment.

 halt against the verified ui797 binding on every check/serve tick. The lock is
 preserved, including when a stop was already latched.
 A changed target config refuses rather than halting an unverified data root.
+On `campaign-instance-changed`, the owner must diagnose the campaign's pin,
+binding (including root and store identity), config bytes and ledger target against
+the original evidence. Restore the original files and target identities if they
+can be verified, or end the campaign; there is no supported retarget or recovery
+command. Never reinitialize, reset or raise the existing campaign, or auto-reclaim
+its lock. A refused target is not proof of a halt or quiescence.
 
 At any cap, deadline or accounting refusal, the supervisor fsyncs `stop.json`
 before invoking the existing `mosaic halt --business ... --json` production CLI
