+## 4.78.0
+**`(feat):`** Add more traceability to `.fern/metadata.json` so generator output makes it
+clearer how and by whom the SDK was generated. The IR `generationMetadata`
+object now carries four additional optional fields:
+  * `invokedBy`: source of the CLI invocation (`autopilot`, `autorelease`,
+    `ci`, or `manual`). Set explicitly via the `FERN_INVOKER` environment
+    variable, otherwise inferred from standard CI env vars.
+  * `requestedVersion`: the raw value passed to `--version` (e.g. `AUTO` or
+    `1.2.3`) so consumers can tell whether auto-versioning was requested.
+  * `ciProvider`: the name of the CI provider (e.g. `github`, `gitlab`) when
+    running in CI. Only the provider name is recorded — no repo, run,
+    branch, commit, or actor metadata is captured.
+  * `originGitCommitIsDirty`: whether the Fern configuration repository had
+    uncommitted changes at the time of generation.
+
+The existing `originGitCommit` field continues to record the git commit of
+the Fern configuration repository at the time of generation.

 ## 4.77.0
 **`(feat):`** Add `fern replay` commands to CLI v2: `init`, `resolve`, `status`, and `forget`.
