FDR-0014 recognizer: accept cutting-garden's underscore receipt prefix before its first underscore protocol receipt lands

[sfriedenberg-etsy]

Heads-up / forward-looking — nothing is broken today, but a coordination point is coming.

Background

cutting-garden's RFC 0002 protocol receipts currently carry the hyphen prefix cutting_garden-capture-receipt-<kind>-v1 (e.g. cutting_garden-capture-receipt-git-v1), while its flat per-store-group receipts carry the underscore prefix cutting_garden-capture_receipt-fs-v1. dodder's FDR-0014 capture-protocol-ingestion recognizer keys on cutting-garden's receipt prefix.

cutting-garden has decided (amarbel-llc/cutting-garden#112) to converge on the underscore prefix going forward — the underscore binds tighter than the hyphen, so the canonical grammar is cutting_garden / capture_receipt / <family> / v<N>.

What changes, and when

• Nothing on disk changes now. Existing hyphen-form protocol receipts are frozen and stay readable as-is.
• The convergence is applied forward, at version bumps:
  • New protocol families debut on the underscore prefix at v1 — the first is caldav: cutting_garden-capture_receipt-caldav-v1.
  • Existing protocol families (git, web) adopt underscore at their next version bump (v2).

The ask

Before cutting-garden's first underscore protocol receipt lands (caldav-v1, tracked in cutting-garden/docs/plans/2026-06-18-caldav-protocol-migration.md, Phase 0), confirm/update the FDR-0014 recognizer to accept both:

• cutting_garden-capture-receipt-<kind>-vN (hyphen — existing git/web receipts, frozen)
• cutting_garden-capture_receipt-<kind>-vN (underscore — new families + future bumps), while still distinguishing the flat cutting_garden-capture_receipt-fs-v1 if dodder relies on that distinction.

No deadline pressure yet — caldav-v1 is still at the planning stage. This is a heads-up so the recognizer change can be sequenced before the wire change, not after.

Cross-references

• Reconcile receipt type-string prefix: underscore (fs-v1 / RFC 0010) vs hyphen (RFC 0002 protocol receipts) cutting-garden#112 — the prefix-reconciliation decision (full rationale + discriminator details).
• Implement RFC 0002 + RFC 0003 in the fs plugin: emit merkle-tree receipts, reconcile EntryV1 cutting-garden#43 §4 — first flagged dodder's recognizer keys on the (old) prefix.
• dodder FDR-0014 — docs/features/0014-capture-protocol-ingestion.md.

:clown: Clarifying scope: this is not blocking the cutting-garden caldav migration. The two repos have no build/test coupling, and the dodder↔cutting-garden ingestion path it concerns is unbuilt. cutting-garden's caldav-v1 (underscore) receipts land on cutting-garden's own green tests; this recognizer change only becomes load-bearing once a dodder ingestion integration actually exists to read those receipts. Filed as a forward reminder so the recognizer is ready then, not as a gate now.
