# Task EP.1.1 Activity Domain Foundation - 2026-07-10
## Scope
- introduce the first additive `crm_activities` write model
- add activity API, service, lightweight repository, and read-model shaping
- add foundational UI building blocks for sheet, form, detail, and badges
- preserve legacy lead, opportunity, and quotation follow-up implementations
## Review Summary

- `docs/implementation/task-ar.2-workspace-ui-ux-design-note-2026-07-07.md`
- `plans/task-eng.0.md`
- existing follow-up services and route handlers under `src/features/crm/leads/**`, `src/features/crm/opportunities/**`, and `src/features/crm/quotations/**`
- existing CRM security, audit, and customer detail foundations
## Foundations Reused
- `src/lib/auth/session.ts`
- `src/features/crm/security/server/service.ts`
- `src/features/foundation/audit-log/service.ts`
- `src/features/foundation/display/server/display-resolver.ts`
- existing customer, lead, opportunity, and quotation detail services for primary-record access validation
## Implementation Notes
- `crm_activities` is additive and does not replace existing follow-up tables or audit-backed lead follow-up behavior.
- activity visibility reuses resolved CRM scope plus owner/assignee visibility and an internal-only rule for manager/admin style access.
- pricing-sensitive activity content is redacted when tied to quotation or PO context without quotation pricing visibility.
- follow-up adapters are documented as candidate contracts only in this phase. No data migration or dual-write was introduced.
## Follow-up Gap Analysis
1. Lead follow-up is still audit-log-backed rather than row-backed, so migration needs an adapter that can translate immutable audit entries into activity candidates without rewriting history.
2. Opportunity follow-up is row-backed and is the cleanest EP.1.2 consolidation seam.
3. Quotation follow-up is row-backed and can follow the same adapter path as opportunity follow-up, but pricing visibility rules must stay active when notes expose commercial values.
4. Dashboard and report consumers still read legacy follow-up data today, so EP.1.2 needs continuity checks before any shared activity projection becomes source input.
## Migration Preparation Report
- prepared:
- shared activity write model
- route-handler boundary
- service-owned lifecycle validation
- repository/read-model split
- projection contract interfaces
- basic activity UI foundation
- deferred intentionally:
- timeline projection
- calendar projection
- notification fan-out
- legacy follow-up storage migration
- dashboard/report dataset swap
## Verification Plan
- run `npm run typecheck`
- run `npm run db:generate`
- run targeted manual API smoke checks for create, update, assign, complete, cancel, reschedule, delete
## Residual Risks
- current activity creation UI uses manual primary record id entry because source-record pickers are intentionally deferred to later workspace integration work
- contact primary-record validation remains lightweight and should be revisited when customer workspace activity embedding begins
