PRs to refine/move to close

IPLD timestamping PR - needs a little more work? need to discuss OED's "string discriminant" proposal
- oed: string registered in namespaces profile per-namespace
  - each namespace should have at least one option AND A DEFAULT if not present in the entry
  - chunny: errors for cross-type/invalid bytes? oed: yes spec should tell you to drop anything with bytes that don't match declared types
- chunny: I was thinking of multicodec as fail-over or backup, but maybe that's too chaotic across contexts
- oed: but navigating this blind, it'll just be bytes, they won't be sniffable
StreamSync PR - needs to incorporate Spencer's input? Are any non-Ceramic streams or systems using this, and would it make sense to find one?
- likely to close soon anyways-- will reopen later if multi-company usecase emerges
DagJWS - I think this just needs an editorial pass for clarity of the "profile"/semi-normative nature of some statements?
- oed: A diagram or even an example CAR file...
- Zach: This is more like a profile for DAG-JOSE... (Joel: That context is hard to reconstruct for the casual reader, tho)

UCAN spec generally
UCAN<>ReCap progress?
- Ceramic waiting on Spruce for recap/ucan feedback (ping @chunningham)

[ ] @oed will ask UCAN group if prf as JWS header make sense to align
[ ] @oed and @bumblefudge to do CLA-bot things offline
[ ] @chunningham to respond to eth magicians post after discussion w/team
- quick read - LGTM w/full URIs, but will discuss
- chunny: where this headed? oed: IPLD shared receipts baybee
- chunny: not just timezone but also precision (nanoseconds vs seconds) - varsig should specify
