 **A crew thread no longer creates threads itself. It asks its Captain, so every new thread joins a crew from the start (R68). The Capy skill also warns that `tools.capy.read` returns a cut-down view of long files.**
 
 ### Changed
-- **docs/captain.md** has a new section, "New threads join the crew". A crew thread asks its Captain for a new thread, and the Captain creates it in the crew. A thread the crew thread already made gets reported by code in that turn, so the Captain can add it with `crew.add`. A thread in another project goes Captain to Captain: the receiving Captain creates it in its own crew as work, briefs it and returns the result. Only a project with no Captain lets the crew thread create the thread itself, with the code recorded on the work's issue. The cause: GBRA-240 created GBEV-33 directly in another project, and that thread ran outside every crew.

 - **The Capy factory context (`factory.md` point 12)** now has the short version and cites that section. Its byte budget in `test/capy-skill-wrapper.test.ts` goes from 3,300 to 3,450: the page's new size rounded up to the next 25 bytes, and no other point was trimmed.
 - **The Capy skill's host adaptations** say that `tools.capy.read` returns about the first 38,000 characters, with each line cut at 2,000. So a read, change and `tools.capy.write` program saves a truncated file, Drive files included. Edit long files with `tools.capy.edit`, or read and write the whole file in bash or Python and check the line count. `tools.drive.history` restores a recent version. This is how the org knowledge base's rules.md lost 37 rules. The skill's context-budget ceiling (`test/fixtures/context-budget.json`) goes from 5,315 to 5,425 tokens, the measured 5,409 rounded up to the next 25, for this one line.
