Migration 055 adds the structural pieces the issue's PA-derivation premise
needed (the design-§1.3 verify-before-trust check found all three were
missing today):
- paliad.partner_unit_members.unit_role text DEFAULT 'attorney'
CHECK ('lead'|'attorney'|'senior_pa'|'pa'|'paralegal') — per-unit role
distinction so derivation can target specific tiers without re-
introducing a firm-wide rank column. The same human can be 'attorney'
in one unit and 'lead' in another.
- paliad.project_partner_units junction (project_id, partner_unit_id,
derive_unit_roles[] DEFAULT {pa,senior_pa}, derive_grants_authority bool
DEFAULT false, attached_at, attached_by) with composite PK and RLS
(read = can_see_project; write = global_admin OR project lead).
- paliad.approval_role_from_unit_role(text) helper used by Phase 3 when
derived authority is consulted by the t-138 ladder.
- paliad.can_see_project extended with one EXISTS branch — derivation
walks the path: a user is visible on P if any (ancestor of P) is
attached to a unit they are a member of with a matching unit_role.
No RAISE EXCEPTION (Maria's build constraint). Day-1 deploy = zero
behaviour change because every existing unit member defaults to
unit_role='attorney' and the default derive_unit_roles is {pa,senior_pa},
so until both diverge no derivation happens.
Backend services
----------------
- DerivationService (new, internal/services/derivation_service.go):
AttachUnitToProject, DetachUnitFromProject, ListAttachedUnits,
ListDerivedMembers (path-walking dedupe by closest attachment),
ListDescendantStaffed (descendant-direct rows excluding ancestor-
already-staffed), EffectiveProjectRole (returns role + source ∈
{direct, ancestor, derived} for the t-138 approval gate in Phase 3).
- PartnerUnitService extensions:
PartnerUnitMemberDetail gains UnitRole (db:"unit_role"). Constants
UnitRoleLead/Attorney/SeniorPA/PA/Paralegal + isValidUnitRole.
SetMemberRole(callerID, unitID, userID, role) with admin gate, prior-
role read in tx, audit emit 'member_role_changed'. ListMembers and
ListWithMembers SELECT projection now includes pum.unit_role.
Handlers
--------
- GET /api/projects/{id}/partner-units → ListAttachedUnits
- POST /api/projects/{id}/partner-units → AttachUnitToProject
- DELETE /api/projects/{id}/partner-units/{unit_id} → DetachUnitFromProject
- GET /api/projects/{id}/team/derived → ListDerivedMembers
- GET /api/projects/{id}/team/from-descendants → ListDescendantStaffed
- PATCH /api/partner-units/{id}/members/{user_id}/role → SetMemberRole
- Services bundle gains Derivation; cmd/server/main.go wires it.
Frontend (Team-tab on /projects/{id})
-------------------------------------
Three new subsections rendered after the existing direct+ancestor table:
- "Aus Unterprojekten" — descendant-direct rows with attribution arrow.
- "Abgeleitet (Partner Unit)" — derived rows with [Sicht] / [Sicht & 4-
Augen] badge per the m-locked honesty rule (§3.5).
- "Partner Units" — attached-unit list with attach/detach controls
(lead/admin only) and a form picker for derive_unit_roles +
derive_grants_authority.
Each subsection is hidden when its data is empty (Partner Units block
also surfaces for managers when empty so they can attach).
Loaders + state in projects-detail.ts; renderTeam orchestrates all
four subsections; renderAttachedUnits owns the unit list + detach
handlers; initAttachUnitForm wires the picker + checkbox role-set.
canManagePartnerUnits gates the attach UI on global_admin OR direct
'lead' on the current project.
i18n keys (DE+EN, ~30 new) under projects.team.section.*,
projects.team.derived.*, projects.team.units.*, unit_role.*. Codegen now
emits 1605 keys (was 1494).
CSS additions: .entity-section-heading (subsection h3),
.derived-badge / .derived-badge--authority, .form-checkbox.
Phase 3 (approval extension to honour derived_peer decision_kind) stacks
on top — gates on EffectiveProjectRole returning ('role','derived') being
wired into the t-138 canApprove + inbox SQL.
F-6 from t-paliad-074 architecture audit. The Gitea repo was renamed
m/patholo → mAi/paliad → m/paliad, but go.mod still declared
`mgit.msbls.de/m/patholo` and every internal import echoed the
pre-rebrand name.
Sweep:
- go.mod: module path → mgit.msbls.de/m/paliad
- All *.go files: imports rewritten via sed
- README.md, docs/design-kanzlai-integration.md: mAi/paliad → m/paliad
- Frontend issue-reference comments (mAi/paliad#N → m/paliad#N) in
i18n.ts, theme.ts, sidebar.ts, app.ts, Sidebar.tsx, PWAHead.tsx,
global.css
Verified: go build/vet/test ./... clean, bun run build clean,
no remaining mgit.msbls.de/m/patholo or mAi/paliad references
outside docs that intentionally describe the rename history.
Backend rename (frontend lands in next commit):
- Migration 026: rename paliad.departments → paliad.partner_units,
paliad.department_members → paliad.partner_unit_members, junction FK
department_id → partner_unit_id, plus all constraints/indexes/policies.
Pre-drop seed re-runs migration 019's logic to capture any users.dezernat
drift, then DROP COLUMN. Adds paliad.partner_unit_events audit table
with RLS (any-authenticated read, global_admin write).
- models.User.Dezernat dropped. Department / DepartmentMember →
PartnerUnit / PartnerUnitMember.
- DepartmentService → PartnerUnitService (file renamed via git mv to
preserve blame). Every mutation now opens a tx and emits a
partner_unit_events row in the same tx (created/updated/deleted/
member_added/member_removed). Update emits before/after snapshots;
Delete emits BEFORE the cascade so the FK still resolves, then
ON DELETE SET NULL keeps the historical row.
- /api/departments/* → /api/partner-units/*. Handlers renamed.
- New /admin/partner-units page handler stub.
- AuditService UNIONs the new partner_unit_events source as a 4th
branch; handler accepts AuditSourcePartnerUnitEvents.
- user_service: drop dezernat from CreateUserInput / UpdateProfileInput
/ AdminCreateInput / AdminUpdateInput. CreateUserInput gains
PartnerUnitID *uuid.UUID — onboarding can pick an initial unit and
the membership row + audit event are inserted in the same tx.
- Settings tab aliases drop dezernat/department.
- Legacy /dezernate and /departments now redirect to
/admin/partner-units (admins only see it; non-admins land on the
forbidden bounce).
go build / vet / test compile clean.
