OpenPRD 0.2 fixed eight body sections, none of which asked what the thing is
built on or how it earns. The stack got chosen in the first implementation PR
instead of at review, and a PRD could be filled out completely without anyone
writing down who pays. PRD 0006 had already grown a hand-rolled
`## Business model` section, which is the gap showing.
0.3 adds two required sections between `UX Notes` and `Success Metrics`:
- Tech Stack — languages, frameworks, datastores, third-party services, and
anything the work must not depend on. It makes the requirements costable.
- Monetization — the revenue model: who pays, for what, how much, and when.
`_None._` stays a valid answer, but it now has to be said out loud.
Adding required sections would normally invalidate every document already
written, so a document is now held to the section list its own `openprd:` key
fixes. A 0.2 document keeps conforming with eight sections, forever; a 0.3
document needs ten. Adoption is per document, and `logicsrc prd validate
--expect-version 0.3` (new flag, wiring up the validator option that already
existed) reports the stragglers as OP-L-VERSION.
The front-matter schema is untouched — both additions are body sections.
Conformance bundle proves both directions: invalid/missing-monetization.md
fails with OP-C-SECTION-MISSING, and valid/legacy-0-2.md passes unedited.
This repo's own PRDs 0001-0006 stay at 0.2 as standing evidence that the
compatibility rule holds. PRD 0007 records the decision at 0.3.

Reshape OpenPRD from a private single-file (prd/<slug>/prd.md, gitignored) into a
published, numbered proposal collection like BIP/EIP/DIP: prd/NNNN-slug.md +
0000-template.md + a README index, committed to the repo, with a lifecycle
(Draft → Review → Accepted → Final; Rejected/Withdrawn/Superseded).
Tools (e.g. moshcode /prd) consume this to publish PRDs into whatever repo the
user is working in.
- docs/openprd.md — rewritten: numbering, lifecycle, directory layout, conformance.
- docs/openprd/0000-template.md — the canonical template.
- packages/schemas/schemas/openprd-prd.schema.json — 4-digit id, status enum,
authors, discussion/implementation, supersedes/superseded-by.
- fixture updated to 0.2.
