grid.js was classifier-only; make it embed ANY embeddable full-page tool the
cascade resolves as default_tool — classifier (incoming/), transmittal
(staging/), archive (the index) — as an iframe scoped to the current dir
(<dir>/<tool>.html). This is the browse-as-shell bridge from the ADR: browse
stays the top-level app and the heavy tools open in-pane (the gridView), so
navigating to staging/ or archive/ inside browse shows transmittal/archive
without leaving the shell, with ?view=browse falling back to the folder
listing (and the standalone tools still served directly at the no-slash URL).
EMBEDDABLE = {classifier, transmittal, archive}; tables/forms embed in the
preview pane instead, landing/browse don't self-embed. resolveViewMode keys
off grid.availableHere() (now generic). Validated in a containerized browser:
each dir embeds its tool, ?view=browse overrides to the listing.

// grid.js — in-pane tool embed for browse (the browse-as-shell bridge; see
|
|
// ARCHITECTURE.md's ADR). Loads a heavy, full-page tool as an iframe scoped to
|
|
// the current directory so the user gets that tool's full workflow without
|
|
// leaving the browse shell. browse stays the top-level app; the cascade's
|
|
// default_tool decides which tool embeds here.
|
|
//
|
|
// Availability: the cascade decides — `state.scopeDefaultTool` (the
|
|
// X-ZDDC-Default-Tool header) must name one of the EMBEDDABLE full-page tools:
|
|
// classifier (archive/<party>/incoming/), transmittal (…/staging/), archive
|
|
// (the archive index). tables/forms embed in the preview pane instead
|
|
// (table-leaf / form view); landing/browse don't self-embed. Operators extend
|
|
// by setting default_tool on a dir — no code change. Iframe src:
|
|
// <currentDirURL>/<tool>.html. Server mode only (file:// has no server).
