Invert the framework updater from a denylist ("framework owns everything unless
preserved") to an explicit allow-list manifest ("operator owns everything unless
framework"). A path the manifest never anticipated resolves to operator-owned by
the fail-safe default, so it is structurally unreachable by any write or prune.
Root cause (#791): `mosaic update` re-seeds via `install.sh` keep-mode, whose
`rsync -a --delete` + hand-maintained PRESERVE_PATHS denylist wiped operator
paths the denylist forgot (agents/*.conf, policy/*.md, *.local.md, harvester
SOP, tools/_lib/credentials.json, unanticipated fleet files).
- framework-manifest.txt: single SSOT ([framework]/[operator], deny-wins,
UNKNOWN=>operator fail-safe), read by BOTH installers.
- src/framework/manifest.ts: pure resolver (parse/matchGlob/resolveOwnership/
frameworkSubtreeRoots/planPrune) — the testable seam.
- tools/_lib/manifest.sh: bash resolver (compiled globs, fork-free hot path),
sourced by install.sh; parity-tested against the TS resolver.
- install.sh keep mode is now manifest-driven (no --delete): overlay-copy
framework files, scoped-prune only retired framework files inside shipped
subtrees. Operator + unknown paths are never written or deleted.
- file-ops.syncDirectory gains an isOperatorOwned guard; file-adapter derives it
from the shared manifest, replacing the drifted hardcoded preservePaths.
Tests (TDD, red->green):
- HARD GATE test-upgrade-manifest-guard.sh: 10 operator sentinels (incl. an
unanticipated one) survive a keep-mode reseed byte-identical + mtime-unchanged;
retired framework file pruned; secret value absent from output. RED 31 fail on
the old installer -> GREEN 48 pass. Wired merge-blocking into CI.
- manifest-parity.spec.ts (§6.1): bash<->TS agree on 34 paths + subtree roots.
- manifest.spec.ts: 18 tests incl. planPrune property test + shipped-tree
completeness (§6.2).
- test-install-migration.sh F6 flipped: an unanticipated operator fleet file now
MUST survive keep-mode reseed.
