ZDDC 59b5550872 refactor: nest lifecycle slots per-party + add virtual top-level aggregators
May 2026 reshape. archive/ is now the only physical project-root
directory; working/, staging/, reviewing/ move from the project root
into each archive/<party>/ folder. Six top-level URLs become virtual
aggregators served via the cascade rather than disk:

  ssr/mdl/rsk           tables rollups across parties with a
                        synthesised $party source-party column
  working/staging/      browse folder-nav listings of parties with
  reviewing             non-empty content in the slot; per-party
                        URLs 302-redirect to archive/<party>/<slot>/

Mkdir at the project root is restricted to `archive` and `_`/`.`-
prefixed system names — virtual aggregator names and ad-hoc folders
return 409.

Plan Review hardcodes the scaffold convention (archive/<party>/
{reviewing,staging}/<tracking>/); the pre-reshape
on_plan_review.{reviewing_root,staging_root} cascade keys are dropped.

document_controller is now subtree-admin of every archive/<party>/
(not of project-root working/staging/ as before), so per-party
lifecycle slots inherit admin authority through the cascade.

// AppAvailableAt reports whether app's virtual HTML can be served at

// (zddc.IsToolAvailableAt). The convention previously hardcoded here
// now lives in defaults.zddc.yaml and is overridable per-directory
// by operators.
//
// Operators can always drop a real <name>.html file at any path to
// override — that path is served by the static handler regardless of
// this function's result. AppAvailableAt is consulted only when no
// real file exists.
//
// Landing is a special case: the cascade declares it available
// universally (since available_tools concat-merges from the root
// baseline), but the dispatcher only auto-serves landing at the
// deployment root. We enforce that here too so callers don't trip
// over project-deep landing requests.

root = filepath.Clean(root)

}
// DefaultAppAt returns the canonical default tool name for requestDir,
// or "" if no specific tool fits. Used by the dispatcher to decide
// which app to serve at a directory URL with no trailing slash —
// trailing-slash URLs serve the browse app for any directory.
//
// Rules (case-insensitive on canonical folder names), under the
// May 2026 reshape:
//
// - <project>/archive/<party>/{mdl,rsk}/... → "tables"
// - <project>/archive/<party>/staging/... → "transmittal"
// - <project>/archive/<party>/{working,reviewing}/...
// → "browse" (hosts the
// markdown editor plugin)
// - <project>/archive/<party>/incoming/... → "classifier"
// - <project>/archive/<party>/{received,issued}/...
// → "archive"
// - <project>/archive/ → "archive"
// - <project>/{ssr,mdl,rsk} → "tables" (project-
// level rollup virtuals
// with synthesized
// $party column)
// - <project>/{working,staging,reviewing} → "browse" (project-
// level folder-nav
// virtuals — per-party
// URLs 302 to the
// canonical archive/
// <party>/<slot>/)
// - any other directory → "" (no default)
//
// The {mdl,rsk} rule wins over the broader archive rule because the
// table editor is a more specific surface for browsing planned
// deliverables than the archive index. Note: the dir at
// archive/<party>/mdl/ itself IS the table — its table.yaml +
// form.yaml + row YAMLs all live there together (self-contained
// directory).
//
// requestDir and root are absolute filesystem paths; requestDir must
// be under root (otherwise "" is returned).
//
// Phase 3b: delegates to zddc.DefaultToolAt, which resolves the
// answer from the .zddc cascade (operator on-disk + embedded
// defaults). The convention previously hardcoded in the switch
// statement below now lives in zddc/internal/zddc/defaults.zddc.yaml
// and is overridable per-directory by operators.
//
// Project root itself (depth-1) still returns "" — the cascade
// doesn't declare a default tool for it (landing is handled by the
// dispatcher's own depth-1 check).
