FYI tech-debt audit done as a precursor to the the ADR customer-row workbench rebuild; full sweep of /app and /modules surfaced ~80 lines of truly dead UI primitives and one fully-stale module, which have been pruned; the bulk of the visible clutter is the menu sprawl on /workbench and the root launcher, which the ADR's rebuild will collapse rather than the audit

FYI tech-debt audit done; the ADR action item #8 satisfied

Why

The customer-row workbench ADR (delivery/adrs/ADR-0001-customer-centric-delivery-workbench.md, originally filed as coordination/adrs/the ADR and relocated 2026-05-16 since the decision is domain-internal) names a separate tech-debt audit as action item #8 — the menu collapse should not silently absorb stale code in the demoted-route trees. This memo files the audit results so the action item has a referenceable source. The cleanup pass that follows from the findings has already landed.

What was found

The sweep covered every app/**/page.tsx, every directory under modules/, the primitives file app/_components/workbench-ui.tsx (770 lines pre-audit), and lib/. Findings were narrower than expected: the codebase is leaner than the menu sprawl suggests, and most of what looks like dead code is load-bearing cross-domain contract surface that just does not surface in the UI tree.

Truly dead, pruned

Three exports in app/_components/workbench-ui.tsx had zero importers anywhere outside the file and were not used internally:

  • ActionChip — near-duplicate of StatusChip, differing only in font size.
  • ActionButton — form-action mutation primitive built in advance of an unstarted operator-mutation flow.
  • formatDate — date-only formatter shadowed by formatDateTime and formatRelative, which are used.

Removed in this pass. File is down to 692 lines.

modules/integrations/ had zero callers anywhere in the repo (verified by grepping for both the file path and the names of its exports assertAuthorizedSyncRequest, SyncAuthError, SyncRequestAuthDiagnostics). The module was an Airtable sync auth helper for a surface that was either never built or has been replaced. The bash sandbox lacks delete permissions on the mounted repo, so the module is neutralized in place: index.ts reduced to export {}; with a comment naming the cleanup pass, and the test file reduced to a describe.skip block. The directory can be deleted from the operator's shell with rm -rf modules/integrations/ at convenience.

tsc --noEmit passes clean after the pruning (delivery_typecheck exit 0).

Subagent false positives, retained

Initial sweep flagged several candidates that verification rescued:

  • modules/lesson-hold and app/api/v1/delivery/v1/lesson-holds/* — referenced from coordination contracts (contracts/credit-reservation-lock/README.md and three sub-specs at contracts/credit-reservation-lock/). Load-bearing cross-domain API surface; absence of UI callers is by design.
  • modules/dispatcher-inbox — consumed by app/api/dispatcher/inbox/route.ts, the webhook receiver. Load-bearing.
  • modules/lessons route handlers (app/api/lessons/{cancel,complete,debit,no-show,process-outcome}) — cross-domain consumers (Revenue's debit, Coaching's process-outcome).
  • PageShell, PageBody, SectionTitle in workbench-ui.tsx — used internally by OperatorShell. Externally only PageShell is imported (by app/page.tsx), which will go away under the ADR action item #4, but the export stays because the internal usage holds.

Conditionally dead, awaiting the ADR implementation

These die when the rebuild lands, not earlier:

  • app/page.tsx root launcher and its locals (loadHealth, DeliveryHealth, HealthMetric, ArrowIcon) — collapse with the ADR action item #4.
  • app/workbench/page.tsx QUICK_LINKS constant and its grid render — collapse with action item #3.
  • app/_components/workbench-ui.tsx exports PageShell, PageBody, SectionTitle may lose export and become file-local once app/page.tsx is replaced.

Refactor opportunity, not debt

Each demoted route page (/lessons, /locks, /attendance) carries parallel grouping and card-mapping logic. The new modules/customer-workbench/ (per the ADR action item #1) will need similar shapes; an opportunistic consolidation into modules/operator/ helpers is reasonable when the new module lands. Not a blocker for the rebuild.

Bottom line for the rebuild

The audit removed roughly 80 lines of UI primitive code and one dead module. The big visible-clutter payoff is the menu collapse in the ADR's rebuild — the audit's deletions alone would not have moved the operator's experience. The rebuild does. Action item #8 of the ADR is satisfied by this memo.
