Summary

3 files, +98/-45: session-resume stylesheet 35 -> 0 lines, including its CSS_PATH. Textual#226 is merged as da21bbd4784a59e2c6416077d90da30eee87db20; this consumer uses its native declaration API.

Before / After

Before: nested stylesheet selectors identify generic Markdown, Static, container, table and button roles and decide their geometry and colours.

After: NativeLayout supplies one cooperative registration hook. ResumeHeading retains MarkdownH1, ResumeHelp extends Markdown's decoder using the heading LEVEL, and ResumeWarning/ResumeFrame compose NativeTheme + NativeLayout + their original Static/VerticalGroup parents. Table/container/buttons retain DataTable, Center and HorizontalGroup. SessionResumeModal retains DismissibleScreen and its existing store/actions.

The caller remains screens/store.py. Session queries, row keys, actions, selection and dismissal are unchanged. WidgetView is not substituted wholesale: its complete defaults would overwrite inherited Markdown/DataTable overflow, borders and margins.

Deleted decisions and their owners

Deleted the entire 35-line session_resume_modal.tcss and CSS_PATH. Each role owns its irreducible geometry on its class. Warning border/text and frame-border alpha retain actual Styles property descriptors and nominal Variable/TextVariable/Keyword/Percent values.

NativeTheme.apply_native_styles participates in Textual's existing Stylesheet.apply publication, including cache hits and same-name palette refresh through App.refresh_css. Its native_declarations method supports cooperative provider composition. My earlier registration/Mount/theme-signal path was incomplete for KnownPalette.refresh_colours and is deleted, not retained as another invalidation path.

Textual#226 binds NativeDeclaration directly to its property implementation. CSS alone resolves external names. Both paths retain shared substitution, StylesBuilder and PaintState semantics, including automatic contrast and alpha; there is no copied Color.parse shortcut or ColorSystem derivation. A provisional WarningTextColour class was removed because text-warning is an expression rather than the RGB contract.

Evidence and limits

• Final reviewed head34095462775122359861e3e6c7e309f829e621a8 merged as5fde3b5a6818297a72edfcb863a059fa48177d58. Tracked source is clean; retained untracked scripts are preserved. The installed build was independently read as Core04c174d6e8d20b81cbe7f31a467d6eea820d1fab / Toad5fde3b5a6818297a72edfcb863a059fa48177d58 / Textual06317bf19837d9e62fc670767ef5fdf3935d7a73. Installed native provider and stylesheet publication hook match the delivered source; the old stylesheet is absent.
• 10 direct value controls and 6 actual ResumeWarning/ResumeFrame declaration controls returned rc0 after property-owned binding. Artifacts: native-declarations-bind-final and native-consumer-bind-final under /home/ts/.cache/agent-scratch/pi-block-spacing/.
• Two real-node/Stylesheet controls returned rc0 for initial publication and changed variables on the same sheet, including auto75% text and frame20% alpha: native-application-check01.log. No synthetic app or theme signal supplied the result.
• Earlier misleading default-only control and whitespace/alias failures remain retained; they are not passing evidence for corrected epochs.
• Authored Textual regression tests and the affected Toad test tests/textual/test_command_pane_and_resume_modal.py::test_the_resume_modal_lists_a_saved_session_and_returns_it_typed are distinct from executed controls. Author pytest/full suite and physical dialog equivalence are not claimed. claude-ai owns the shared parser execution.
• Final hosted NRA gate41503896727/job125478091521 passed at340954627; suite SKIPPED. The author's exact-head source judgment and explicit growth reasons are recorded, not represented as independent execution. Earlier c89509 failed because the library API had not landed; that original failure remains retained. A skipped suite is not a pass.

Assumed: these controls establish specified declaration/publication behavior, not painted geometry, focus, selection or real dialog acceptance. Those affected application cases remain open. P1088's merged spacing source and open physical acceptance are a separate order; its source delivery claim is now recorded at revision17.
