Use the owned Gecko automation browser for locate observations, uploads and downloads.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
Owned Gecko can answer `BrowserInstruct` `action = "observe"` when this
installation selects the `locate` Exact Output. Repeat its observed
`lane = "automation"` and `tabId`; supply an optional `instruction`. The model
chooses only observed node IDs. The worker checks the original document and
target meaning again and returns fresh node observations with a separate
`inference` explanation. A match is not a click or permission to act. Preserve
its documentId/nodeId and perform the normal guarded interaction only when the
user's task authorizes it. A truncated scene does not establish that every match
was found. If locate is disabled or its model route is unavailable, inspect that
configuration rather than moving the tab to another browser.
Uploads use `BrowserAct` `action = "upload"` on an owned Gecko tab
(`lane = "automation"`) with the observed `tabId`. The host must first
authorize and snapshot the requested files through the Keeper's file-read
context. A raw path is not that authority. Never invent an `uploadId` or reuse
a grant from another call.
For owned Gecko downloads, use `BrowserRead` with `mode = "downloads"` and the

The line at the top of this page pins the label git:20261027.4fe0239, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
A 17 of 17 checks passed. Fixed automatic checks with no AI involved, so the same checks give the same answer every run.
