A group's template suppression is "coarse by reference" (path for routes,
handler-name for triggers), and both resolution points dropped ANY inherited
row matching that reference across the whole subtree — including one a NEARER
descendant group deliberately re-declared. So an ancestor group G that declines
a far-ancestor's `/x` (or `audit` handler) would also silently kill a child
group H's OWN `/x` / `audit`-bound trigger at the same reference, violating the
documented "an owner can only decline what it inherits, never a descendant's
own rows" invariant.
Fix: gate each decline on the chain DEPTH of the suppressor vs the target's
owner — a suppressor at depth `d_s` may only decline a row whose owner is
strictly ABOVE it (`target_depth > d_s`):
- Routes: `list_route_suppressions` now returns `(app, path, suppressor_depth)`;
the rebuild folds it to the min depth per `(app, path)` and
`compile_effective_routes` skips an inherited route only when
`route.depth > suppressor_depth`. (This also subsumes the old `depth > 0`
inherited-only gate.)
- Triggers: the dispatch anti-join gains `AND sc.depth < c.depth` (the
suppressor's chain depth below the trigger owner's), correlating on the outer
`chain c` that every kv/docs/files/pubsub match query already binds.
An app's own suppression is depth 0 → still declines anything it inherits; a
group's suppression declines only what that group itself inherits. `sealed`
still overrides. No schema change.
Pinned by a new `compile_effective_routes` unit test (a depth-1 descendant
route survives a depth-2 suppression that declines a depth-3 template) and a
new `group_suppression` DB test (same for triggers); all existing suppression /
sealed / template journeys stay green.
