merge: bring main into the audit and state-map work

main gained six PRs (#1-#6) while the audit fixes and the state-map seam
were in progress. Four of main's commits fixed the same bugs this branch
did, independently; where they overlap, the more complete version wins:

- Fingerprints: main's (a0844bb) - catchSite (`member#index` among all
  catches), union/owner as identity, a legacy fingerprint so version-1
  baselines still match, baseline "version": 2. This branch's `catch`
  ordinal is dropped; its fingerprint_test still guards the result.
- verify --rule: main's verifyAnalysis (cf9e0b7), which also reports
  findings in skipped files as NOT SCANNED.
- Unreadable SDK: both kept - this branch's up-front probe gives the
  early, specific error; main's catch around the analyzer (d6b6bcb) is
  the backstop.
- Riverpod: main's "a ref.listen is not a render" (f6411dc) and this
  branch's AsyncError patterns / stored-value tracking compose; the
  fixture keeps both sets of cases.

Ported onto the model-only rules (the seam), since main edited code this
branch had moved into front-end facts:
- excerpt.dart's literal-free, bounded quoting (a prompt-injection
  guard) now also covers front-end facts: SwallowedFailure.handler and
  NonSubscribingRead.excerpt, and the C++ front end elides string
  literals in handler evidence the same way.
- ScanCoverage: runChecks stays source-free; the model carries coverage
  (`scanCoverage` in the state JSON, written by both front ends), so
  `check --model` states coverage like a source check.
- main's softened wording (rendered-not-emitted "probably unreachable",
  the remove-policy dead-handler text, notifier-field-unread) and the
  backticked flag message.

Docs: main's README grew the Firestore query inventory and the output
contract; the README stays short, the inventory moves to
docs/queries.md, and the contract, exit codes, verify and baseline
details join docs/usage.md.

Checked against origin/main on resolved mirrors of the dogfood apps:
nuwayze (102), dex (0) and word_alive (0) identical; tick differs only
by the intended riverpod stored-value fix. On the fixture every
difference is one of this branch's fixes. 214 tests pass.

+# Firestore query inventory
+
+`pipe queries` lists every Firestore query the scanned code can issue, as
+typed, machine-readable records. It is an **inventory only**: no rules, no
+findings, no baseline, and deliberately no index analysis. Deciding whether a
+query needs a composite index, and probing a live project, belong to the
+consumer of this output, which can compare it against `firestore.indexes.json`.
+
+What it recognises:
+
+- **cloud_firestore chains.** Receivers are identified by **static type and
+  library**: an `InterfaceType` named `FirebaseFirestore`, `CollectionReference`,
+  `Query`, `DocumentReference`, `AggregateQuery`, `Filter` or `FieldPath` whose
+  library URI starts with `package:cloud_firestore/` or
+  `package:cloud_firestore_platform_interface/`. Nothing is matched by name, so
+  `Iterable.where`/`take`, or a project class called `Query`, never is.
+- **One record per terminal call**: `get()` (`realtime: false`), `snapshots()`
+  (`realtime: true`), `count()` / `aggregate(...)` (`aggregate: count|sum|average`)
+  on a `Query` or `CollectionReference`. `DocumentReference.get/snapshots` are
+  point reads that need no index: they are counted in `totals.documentReads`
+  and never listed.
+- `collection(path)`, `collectionGroup(id)` and `doc(...)` segments become
+  `scope`, `collection` (the last collection id) and a `path` pattern such as
+  `stores/*/products`. Document ids are expected to be dynamic and cost
+  nothing; a dynamic **collection** id makes the record `partial`, and a fully
+  dynamic one also sets `collection: null`.
+- `where(...)` with every named operator (`isEqualTo` `==`, `isNotEqualTo` `!=`,
+  `isLessThan` `<`, `isLessThanOrEqualTo` `<=`, `isGreaterThan` `>`,
+  `isGreaterThanOrEqualTo` `>=`, `arrayContains` `array-contains`,
+  `arrayContainsAny` `array-contains-any`, `whereIn` `in`, `whereNotIn`
+  `not-in`, `isNull: true` `==` null, `isNull: false` `!=` null); a field may be
+  a string, `FieldPath([...])` (dotted) or `FieldPath.documentId` (`__name__`).
+  `where(Filter.or(...))` / `Filter.and(...)` become a `composite` node.
+- `orderBy(field, descending:)`, `limit`, `limitToLast` (`limit.last: true`),
+  and any cursor (`startAt`, `startAfter`, `endAt`, `endBefore` and their
+  `...Document` forms) as `cursor: true`. `withConverter` passes through.
+- Strings resolve through literals, adjacent and interpolated strings (`*` for
+  each unknown part), `+`, `const` and `final` variables with a literal
+  initializer, and one-return path helpers (`storePath(id) => 'stores/$id'`)
+  with their arguments bound.
+- **Built queries.** A local `Query` variable is the union of its definitions in
+  its function body; a clause added under an `if`, ternary, `switch`, loop,
+  `catch` or closure is `conditional: true`. Two cuts keep that union honest:
+  an assignment textually after the terminal is ignored unless both sit in one
+  loop, and an `if` that encloses both the assignment and the terminal does not
+  make the clause conditional. Fields are followed through their initializer,
+  constructor initializers and assignments in their class.
+- **Helpers.** A getter, method or function in the project that returns a query
+  is summarised and inlined at its call sites with the call's arguments bound.
+  Methods are inlined **one level deep**; getters and fields take no arguments
+  and do not count against that. A query that arrives as a parameter, or from a
+  call pipe cannot follow, is `origin: unknown`, `confidence: unknown`, with
+  the clauses added locally still recorded.
+- `inLoop: true` when the terminal is inside a `for`/`for-in`/`while`/`do` body
+  or a collection `for`, or inside a closure passed to `Iterable.map`/
+  `forEach`/`expand`, `Stream.asyncMap`, or within `Future.wait(...)`. A fixed
+  `Future.wait([a.get(), b.get()])` is not a loop.

+```
+
+- `filters[].valueType`: `string`, `int`, `double`, `num`, `bool`, `timestamp`
+  (`DateTime` or `Timestamp`), `null`, `list`, `map`, `reference`, or
+  `unknown`; `inCount` is the length of a literal list operand.
+- `composite` (optional): `{op: or|and, filters: [filter | {composite}]}`.
+- `limit`: `{kind: literal|variable|none, value?, conditional, last?}`.
+- `orderBy[].dir`: `asc`, `desc`, or `unknown` when `descending:` is not a
+  constant.
+- `confidence`: `exact`, `partial` (the source is known but something is not:
+  every cause is in `reasons`), or `unknown` (the query's source could not be
+  followed). `origin`: `chain`, `variable`, `helper`, `unknown`, `adapter`.
+- `queries` is sorted by site. Status lines and notes go to stderr, so stdout
+  is exactly the document. `--format md` renders the same data grouped by
+  collection, with the coverage line first.
+
+**Injection policy.** The analysed repository is untrusted (see
+[agent briefs](usage.md#agent-briefs)). The inventory never quotes source: every
+collection, path and field name must match `^[A-Za-z0-9_.*/\-]+$` or it is
+replaced with `*` and a reason is added; owners and members are identifiers.
+
+**Unresolved packages.** If `cloud_firestore` is not in the package graph, or
+an import of it does not resolve, the output says so in `notes` (and
+`unresolvedFirestoreUris`) rather than presenting an empty list as a clean
+result; `--require-firestore` turns that into exit 2.
+
+## Adapter config
+
+Server-side code often wraps Firestore in a declarative API that takes a query
+as data, so there is no chain to follow. `--adapter-config` (YAML, or JSON,
+which is a subset of YAML) tells pipe what such an API's arguments mean. The
+resulting records use the same schema with `origin: adapter`. For a gateway
+like this:
+
+```dart
+abstract class FirestoreGateway {
+  Future<List<QueriedDoc>> queryCollection(String collectionPath,
+      {List<WhereEquals> filters = const [], WhereArrayContains? arrayContains,
+       List<WhereRange> ranges = const [], List<OrderBy> orderBy = const [],
+       String? startAfterId, int? limit});
+  Future<List<QueriedDoc>> queryCollectionGroup(String collectionId,
+      {List<WhereEquals> filters = const [], WhereIn? inFilter,
+       WhereArrayContainsAny? arrayContainsAny, List<WhereRange> ranges = const [],
+       List<OrderBy> orderBy = const [], int? limit});
+}
+abstract class FirestoreTransaction {
+  Future<List<QueriedDoc>> queryCollection(String collectionPath,
+      {List<WhereEquals> filters = const [], int? limit});
+}
+// WhereEquals(field, value), WhereIn(field, values), WhereArrayContains(field, value),
+// WhereArrayContainsAny(field, values), WhereRange(field, {gte, gt, lte, lt}),
+// OrderBy(field, {descending = false})
+```
+
+the config is:
+
+```json
+{
+  "adapters": [{
+    "interface": ["FirestoreGateway", "FirestoreTransaction"],
+    "library": "package:nuwayze_functions_dart/src/data/firestore_gateway.dart",
+    "methods": {
+      "queryCollection": {"scope": "collection", "path": 0},
+      "queryCollectionGroup": {"scope": "collectionGroup", "path": 0}
+    },
+    "args": {
+      "filters": "filters", "arrayContains": "filters", "arrayContainsAny": "filters",
+      "inFilter": "filters", "ranges": "filters",
+      "orderBy": "orderBy", "limit": "limit", "startAfterId": "cursor"
+    },
+    "types": {
+      "WhereEquals": {"field": 0, "op": "==", "value": 1},
+      "WhereIn": {"field": 0, "op": "in", "value": 1},
+      "WhereArrayContains": {"field": 0, "op": "array-contains", "value": 1},
+      "WhereArrayContainsAny": {"field": 0, "op": "array-contains-any", "value": 1},
+      "WhereRange": {"field": 0, "ops": {"gte": ">=", "gt": ">", "lte": "<=", "lt": "<"}},
+      "OrderBy": {"kind": "orderBy", "field": 0, "descending": "descending"}
+    }
+  }]
+}
+```
+
+- `interface` (a name or a list) + `library`: a call matches when the invoked
+  method's enclosing class is one of these interfaces from that library, or a
+  class implementing one. Names alone never match.
+- `methods.<name>`: `scope` (`collection` | `collectionGroup`), `path` (the
+  argument holding the path or group id), optional `realtime: true`.
+- `args.<named argument>`: a role - `filters` and `orderBy` (a value object, a
+  list literal with `if`/`for`/spread elements, a ternary, or a local list built
+  with `add`/`addAll`; elements under an `if` are conditional), `limit`, or
+  `cursor` (any non-null value).
+- `types.<class>`: how to read one value object, matched by class name and
+  library (the adapter's, or `library:`). `field` and `value` are a positional
+  index or a named argument. The operator is either fixed (`op`), one per
+  present named bound (`ops`), or read from an argument (`opArg`) and mapped
+  through `opMap`, keyed by enum constant name or string value
+  (`{"opArg": 1, "opMap": {"lessThan": "<", "greaterThan": ">"}}`).
+  `kind: orderBy` with `descending` reads an ordering instead of a filter.
+- Every operator must be one of `==`, `!=`, `<`, `<=`, `>`, `>=`,
+  `array-contains`, `array-contains-any`, `in`, `not-in`; a config that names
+  anything else, an unknown role, or a bad scope is refused with exit 2.
+
+## Limits
+
+- Flow-insensitive within a function, apart from the two cuts above: a clause
+  on a path that returns early is still in the union (as conditional).
+- Helper methods are inlined one level deep. A query-consuming wrapper - a
+  method that takes a `Query` parameter and calls `get()` itself - is reported
+  at its own terminal as `unknown`; the clauses its callers pass in are not
+  attributed to it.
+- A collection name taken from a loop variable over a constant list, a map
+  lookup or a runtime value is `*`, with the record `partial`.
+- No index analysis, by design: the output carries what an index check needs
+  (scope, collection group, equality vs. range vs. array operators, order
+  directions, `in` sizes) and leaves the decision to the consumer.
+
+## Calibration
+
+Calibrated on the NuWayze app (Flutter, `lib/`, 827 files) and its Dart backend
+(`functions-dart`, 147 files, with the config above), 2026-09-23:
+
+| package | extracted | independent count | exact / partial / unknown |
+| --- | --- | --- | --- |
+| app | 372 query terminals + 165 document reads | 372 `get`/`snapshots`/`count`/`aggregate` calls whose receiver resolves to `Query`/`CollectionReference` (336 + 36) | 336 / 28 / 8 |
+| backend | 136 adapter calls | 136 `queryCollection(`/`queryCollectionGroup(` call sites by grep | 121 / 15 / 0 |
+
+Every `partial` is a genuinely dynamic collection or field name; the 8
+`unknown` are query-consuming wrappers (a `Query` parameter, or a wrapper that
+applies caller-supplied builder closures). Zero false positives were found:
+records exist only where the receiver type resolves into cloud_firestore.
