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.

The chooser completes its three tiers: bundled by template order, then
keyed user templates, then keyless boards by display name — and a
malformed user template still lists, by folder name with the loader's
own sentence on the row, never failing its neighbours. The store is
re-scanned on every presentation and on app activation, the Reveal
round trip made honest without watching a folder 09 deliberately
leaves unwatched; Reveal lives in the chooser's header and mints the
store on first press. Save as Template repeats Duplicate's sequence —
progress row with Cancel, flush, detached cancellable copy — through
the engine: mint the store, read the next user order before the copy
can count itself, Finder-ladder the name, copy excluding .git and
.trash/, then stamp the whole template: mapping on the landed copy
through updateIndex, with no bracket because the copy lives outside
every watched board. Folder attributes deliberately don't carry — the
one lock the command stays live under is the read-only-DMG one, and
carrying its mode bits would mint a read-only template in the user's
own store; the command gates instead on the real hazard, unsaved card
content. A signpost names the template only when the ladder renamed
it. One name ladder now serves Duplicate and the store.

A template is a board folder the ordinary loader reads — no second
schema, no Swift catalog. BoardTemplate became exactly that: a loaded
BoardModel with chooser-facing derivations, the lane-title stub gone.
TemplateEngine instantiates by the copy-remint-restamp walk: .git and
.trash excluded at top level only — both names mean something at a
board root and nowhere else, and .gitignore must survive — every
materialized folder reminted, created/modified stamped fresh (born
today, not forked), modified-by cleared, the template: key carried
inert, the blurb and style inherited, and loose card files normalized
at this import boundary per the paste precedent so a new board never
opens with a notice about a mess its own birth made. Legacy deleted:
keys copy through verbatim to the one migrator — stripping would
resurrect, skipping would destroy. Atomicity is construct-then-clean:
a sibling temp can be sandbox-refused and a cross-volume rename is
just a second copy, so the call removes what it created on every
non-board exit and never touches an occupied destination. The
cancellable per-item walk extracted into BoardTreeCopy serves
Duplicate and instantiation with two parameters — top-level exclusions
and folder-attribute carriage, the only axes they differ on.
