mcp: glyph_seal — standalone seal companion (0.3.0 push, PR 2/5)#110
Merged
Conversation
Tier-2 of the 0.3.0 push: provenance verb completeness. glyph_verify
already existed (re-render-and-compare). The missing companion is
glyph_seal: emit the provenance block as JSON, no SVG, no embedding.
Use cases this unlocks:
- Store the seal next to an audit log entry; verify later without
keeping the rendered SVG around
- Sign the seal with an external key (regulated-industry workflow)
- Pipeline cases where the SVG is rendered downstream and the seal
must travel separately
Same hash inputs as the seal embedded in renderSvg's SVG <metadata>
block, so a standalone-sealed JSON object verifies cleanly against
the SVG returned by glyph_render against the same (spec, rows,
schema) tuple.
Tests: 4 new in server.test.ts covering deterministic hashes, round-
trip with glyph_verify, invalid spec rejection, and self-contained
chart specs (hierarchy/function data with empty rows).
190/190 @glyph/mcp tests pass. Biome clean.
