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.

OpenPRD has existed as a document (docs/openprd.md), a front-matter schema, a
template, and this repo's prd/ collection. Nothing enforced it. This adds the
reference implementation.
@logicsrc/openprd
- parser: front-matter + the eight `##` sections + numbered requirements.
`###` stays content so a long Requirements section can be organized, and
headings or R#-shaped lines inside code fences are ignored
- validation splits the standard's four conformance rules (filename,
front-matter schema, id-matches-prefix, eight sections in order) from
lint (empty section, missing priority tag, numbering gaps, duplicate R#,
date order, one-sided supersession, stale index). Conformance failures are
errors; --strict promotes the rest. Stable codes, file, line, hint
- collection rules the per-file view cannot see: unique ids, monotonic
numbering with no gaps, 0000 reserved for the template, cross-references
that resolve
- lifecycle enforced rather than advisory: Draft cannot jump to Final,
terminal statuses do not resume, Superseded must name its replacement
- deterministic index generation, so `prd index` is idempotent and CI can
diff it
- front-matter rewriting that leaves the body byte-identical
- the optional LogicSRC task bridge the standard describes: each R# becomes
one logicsrc.task, validated against logicsrc-task.schema.json before it
is emitted; creator DID derived from the author email
CLI: logicsrc prd init|new|list|show|validate|lint|index|status|next|tasks|
export. Exit codes stable for CI (0 ok, 1 invalid, 2 usage, 3 not found).
Conformance bundle: packages/schemas/fixtures/openprd/ — 6 documents that must
validate and 12 that must fail, each naming the error code it must produce.
Several rules depend on the filename, so every fixture records the name it is
validated as.
Docs: an Implementation section in docs/openprd.md (CLI, validation model,
task bridge, conformance bundle), the spec added to the site's docs surface,
nav and sitemap entries, and a README section.
Verification: 76 new tests; full monorepo build and all 451 workspace tests
pass. The suite dogfoods this repo — prd/ validates with zero errors and zero
warnings, the embedded template is byte-identical to docs/openprd/0000-
template.md, and all 210 requirements in PRD 0001 map to schema-valid tasks.
prd/README.md is regenerated by the tool it now ships.

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.

OpenPRD is a lightweight, single-file PRD standard (prd/<slug>/prd.md) for
humans and AI agents — the low-ceremony counterpart to OpenSpec's multi-file
change bundles. PRD documents are private by convention; only the standard is
published here.
- docs/openprd.md — the standard: file layout, front-matter, the 8 required
body sections, privacy, and the optional bridge to LogicSRC tasks.
- packages/schemas/schemas/openprd-prd.schema.json — front-matter manifest schema.
- packages/schemas/fixtures/openprd-prd.yaml — a valid manifest fixture.
- packages/validators — register the openprd-prd schema.
