v2.7

FieldObj bit 20 corrected (override data formatting with value list, inverted, not an edit box marker). Anchor conversion rule and bit 10 naming added.

v2.6

Excellent external contributions, measured to the repo's own standard by Hiromine Fujita (issues #1 and #2). Integer CSS lengths written 1.0pt are dropped at paste, so write 1pt (§26.2, §23). Pasting a theme mints a fresh custom-theme UUID, so capture ThemeName after the paste, not from the theme XML you pasted (§0, §28.1). And the mismatch mechanism pinned down along the way: on a wrong ThemeName the object is rebuilt from FullCSS with supplied LocalCSS discarded (§25.3). All three behaviours round-trip confirmed first party before release.

v2.5

Object anchoring verified. WebViewer handling enhanced. Earlier flag readings corrected from production feedback. Token reduction pass across the spec.

v2.4

Full closure pass against FileMaker Pro 26.0.1.51. Observed items now fully verfified - production testing will continue

v2.3

Eight mechanisms corrected by round trip verification against FileMaker Pro 26.0.1.51. The spec is now close to fully verified.

v2.2

Continued verification and hardening

v2.1

We found a real FileMaker bug — and fixed it (see "Multi-object Text/Button paste corruption and the fix"). Plus: Portal behaviour completely re-verified end to end (several long-standing assumptions turned out wrong once actually tested), and a fresh batch of field/formatting rules confirmed. The most rigorously tested release yet.

v2.0

Layout XML Skill — v2.0

Reverse-engineered specification of FileMaker's undocumented layout clipboard format. All 18 object types documented, flag bits decoded, element-ordering constraints and silent failure modes confirmed across production layouts. Packaged as a Claude skill with the full specification in references/.
