 - **A route belongs to the handler it is declared on.** SARIF used to attach routes per file, first declaration wins. In a file that declares `GET /orders/<id>` on one handler and `POST /pay` on another, an injection on the `POST /pay` handler was exported with `codegraph_reachability` set to `GET /orders/<id>`, and a consumer probed the wrong endpoint. Each exposure and confirmed result now takes the route declared on its own handler, else its file's route, else its asset's inbound route. `properties.route_attribution` (`handler`, `file` or `asset`) says which step found it. When the model does not tie a finding to one route, the result carries `route_attribution: "ambiguous"` and `route_candidates`, and no `codegraph_reachability`. **Expect** some results that used to carry a route to carry candidates instead. Those routes were guesses.
 - **A `@mitigates` no longer clears the same asset and threat on a sibling handler.** Coverage was keyed by (asset, threat) for inline annotations. One `@mitigates #orders against #idor` on `update_order` therefore removed the `@exposes #orders to #idor` on `get_order` and on `delete_order` from `validate`, `ci` and `sarif`. When an exposure and a mitigation in the same file are both attached to handlers, the mitigation now covers the exposure only if its handler encloses the exposure's handler: the same function, or a class around the method. A mitigation in a module header, or in another file, covers as before. **Expect** an inline repository with per-handler mitigations to report more open exposures. Each one was already declared and was being hidden. Measured: no exposure changes state on this repository or on the external-mode test fixture.
+- **Every hop of a multi-hop `@flows` gets the whole line.** In a `.gal` sidecar, only the first hop of `A -> B -> C` was sited at its `@source` block; the others were sited at the `.gal` file itself, so they had no handler and no anchor and pointed readers at the sidecar rather than the code. And a `-- "…"` continuation line extended the description of the last hop only. Both now apply to every hop, as SPEC §3.2 `@flows` (Chains) states, and `conformance/flows.json` pins them.
 - **`@flows A -> B via -- "d"` is reported as malformed.** It used to record `-- "d"` as the mechanism and lose the description. `via` must be followed by a mechanism, the same rule that already rejected a trailing bare `via`.
 - **The annotation guides no longer forbid chains.** The agent prompt and `docs/GUARDLINK_REFERENCE.md` said "ONE source → ONE target per line", which the parser has not enforced since chains were added. They now describe one path per line, with chains, and show the route form.

 **Mechanism.** `via` is optional. When present, the mechanism is all the text after `via ` up to the ` -- "` that opens the description, or to the end of the line, with surrounding whitespace trimmed. It may contain spaces, dots, slashes and punctuation: `via TLS 1.3`, `via TypeORM.findOne`, `via POST./restore (multipart)` are all single mechanisms. A flow **without** `via` is a complete flow whose channel is unstated; its mechanism is `null`, and it takes part in the data-flow graph, the diagrams and undefended-path analysis exactly as a flow with one does. A reader MUST NOT drop it.
