The 2026-07-29 integrity design pass, consolidated (DESIGN/01 -
Validation and healing; DESIGN/02 - Components): IntegrityRules
(Storage, pure) is the one home for the identity predicate and
canonical form (BoardWriter.canonicalIdentity deleted, ItemID and the
loader forward to it), the per-field rulebook, uneditable shapes,
per-kind index validation, the reserved-name tables, and the trash
kind discriminator (values trusted - kind: lane/card explicit,
unrecognized falls to shape). LoadResult's ad-hoc channels fold into
one typed Defect stream (looseCardFiles / legacyTombstone /
claimedNameSquatted, per-defect heal signatures); the old accessors
survive as computed views.
HealScheduler (LiveStore) states the six-step heal pattern once -
resting-clear, lock gate, isWritableFile gate (now covering all four
heals), signature memo armed-before-attempt with explicit
clear-on-success, disk re-verify in each write half, one banner-posture
table (BannerCenter keeps all phrasing). The three hand-rolled healers
run on it with behavior preserved - including the
relocation-notice-despite-partial-failure quirk, deliberately. Heals
run at the reload tail AND at registry acquire, closing the
migration-never-fires-at-open asymmetry. Displacement runs first: a
squatted .trash would otherwise fail the migration and arm its memo
against an unchanged picture.
Claimed-name squatters (ruled today, 62c47a2) displace by the shared
Finder-style rename ladder - preserved verbatim, symlinks moved as
links, nothing stamped; AgentGuide's untouchable-skip upgrades to
displace-then-write, the CLAUDE.user.md-taken skip stands. kind stamps
on every create and backfills on any index rewrite via the on-touch
seam (placement resolver stamps nothing when the parent is unknown -
a guessed kind is worse than an absent one; board-root writers declare
theirs). Heal writes mark their EchoLedger receipts (inert in base;
pro-m1's committer will split them into their own commits). The
renumber ask-renumber-ask-again two-step is one shared helper, adopted
at all nine call sites.
69 tests added. 1738 green on both schemes.

Two registries (Kanban/LiveStore/): BoardStoreRegistry shares one live
store and one started, fully wired watcher per open board across its
windows — keyed by file identity (fileResourceIdentifier), never path,
refcounted to order teardown; release matches by store identity so a
board renamed while open can't leak its watcher. BoardRegistry persists
app-private per-board state in Application Support as diff-stable JSON:
records anchored by security-scoped bookmarks, recents = the registry
sorted by lastOpened (counts registry-cached, never scanned), graceful
orphaning with Forget, corrupt files quarantined aside, and files-first
verified — the board tree is untouched byte-for-byte. Timestamps use
ISO8601DateFormatter with fractional seconds: the FormatStyle variant
truncates-then-rounds and drifts a millisecond per round trip.
16 registry tests; full suite 297 tests in 56 suites green. Four
findings filed on the Redesign board.
