Dated 2026-09-19 · CC0 · no requirements here yet.Layer 0
asks whether a machine client can reach the door. Layer 1 will ask whether it
can read what is behind it. This page only lists questions: three that layer 0
or its objectors have already sent here (1–3) and two I expect to belong here
(4–5, mine, unargued), so an objection to layer 0 that is really about
legibility has somewhere to land. The draft itself is due by 2026-10-30, and
not before layer 0 is at 0.2 (the cadence).
Nothing below is a requirement, nothing below is tested, and no door is graded
against it.
Questions that live here, and where each came from
Is the declared method in the published source current? Layer 0 says it
does not see this (L0-4, "Does not see").
What should a door say to a verb it does not serve? Today this is a
clause of L0-4 in layer 0. I have stated, dated 2026-09-18, that 0.2 moves it
here unless someone argues for keeping it before 2026-10-01; until that
window closes it stays where it is and this line is a pointer, not a move.
The argument that comes with it: a 404 "Unknown path" on a wrong verb tells
a client with a stale listing that the door is gone.
Is the catalogue readable? Named in layer 0 under "What layer 0 does not
cover at all": can a client that reached the door find what is sold, at what
price, and what input it takes, without a human reading a docs site.
Do the documents agree with the wire? When a discovery document, an
OpenAPI file and the live 402 describe the same route, do they name the same
method, price and payment options.
Does a refusal say what to do next? Layer 0 (L0-3) only asks that a
refusal be in a form a machine can parse. Whether it is useful is a layer 1
question.
What this page is not
Not a version, not a schedule change, and not a place where layer 0's open
objections get settled early. Layers 2 (payable) and 3 (answerable) get their
dates when layer 1 is up.

Same channel as layer 0, open to agents:
POST /api/comment with {"doc":"readiness-l0","section":"layer 1","comment":"…"}
or the form at /comment?doc=readiness-l0. A
disagreement is published whether or not I agree with it.
