Module migration 

Profile migration, mirroring js/src/browser/migration/index.js.

Copies a person’s data from a real browser profile into a dedicated target profile, one data class at a time, and returns the report shape documented in docs/cli-and-bridge.md. Nothing is ever written to the source profile, and every database read goes through a consistent read-only snapshot, so the migration is safe to run while the source browser is open.

Cookies are returned (not written): a running Chromium re-derives its own cookie encryption, so the launcher seeds them over CDP with the existing seed_cookies path. Every other data class is written into the target profile directory.

Structs

KeystoreHooks

The OS keystore calls a migration makes. The defaults use the same command-stream backed readers as read_browser_cookies.

MigrateProfileOptions

Options for migrate_profile.

MigratedCounts

Per-class migrated counts.

MigrationEntry

One skipped item or warning in a migration report.

MigrationKeys

Injected password keys (keys in the JavaScript API).

MigrationReport

The full result of migrate_profile, including the cookies to seed.

MigrationReportSource

The source a migration read from.

MigrationSource

Where to migrate from (from in the JavaScript API).

MigrationSummary

A migration report without its cookies, as launch_real_browser returns it (the cookies are seeded, never echoed back).

PrimaryPasswordError

A primary (master) password blocks decryption.

TargetKey

A target profile’s encryption key and the version prefix to write.

Constants

ALL_DATA_CLASSES

Every data class a migration can copy, in the order they run.

DBSC_BOUND_COOKIE_NAMES

Rotating Google session-token cookies that DBSC binds to the device key.

MIGRATED_PREFERENCE_PATHS

Dotted paths copied from the source Preferences into the target.

Functions

migrate_profile

Migrate a browser profile into a dedicated target profile directory.

Type Aliases

CookieReader

Reads installed-browser cookies; the default is read_browser_cookies.

SafeStoragePasswordReader

Reads a Safe Storage password for (browser, platform).

SourceKeyResolver

Resolves the source profile’s decryption key for an encryption prefix (v10/v11). Linux uses a hardcoded key for v10 and the keyring for v11. Keys are cached per prefix, including failures.

WindowsKeyReader

Reads and DPAPI-unwraps the key in a Windows Local State file.
