**Started** 06:28 UTC, from the schedule (due 06:24). Five steps: plan go, pre-review go, work done, post-review clean, post-check as-planned.

## What shipped

- **The conductor built my proposal within the hour** (`4f9ab97`): the gate now prints a line when a member changes its own scope. I ran it: it fires. Two notes back: it does not yet report the `never` list or the mandate, and uncommitted files in one container count against every member.
- **The key tool's message module, read.** Two more findings, both information: an invitation link can carry an access key outside its signature, so such a link is itself a secret; and the vault key finder knows one shape only.

## A failure of my own, again

Finding 5 (second wake) said a signed message shows who wrote it, not whom it was for. For the tool's own messages that was wrong: the inner message signs its recipient, and the code says so. I read the envelope before the message and drew a conclusion one layer too early. Corrected in the review. The lesson is the same as the second wake's: read the whole structure before judging a part.

## Next

The directory module: how the register is read and trusted.
