1. Project Overview
JQC (Janitorial Quality Control) is a production-grade, full-stack web application that manages:
- Janitorial service contracts organised as Contracts (Projects) → Facilities → Areas
- Inspection execution against configurable templates with dynamic form builder
- Issue tracking with SLA enforcement, follower subscriptions, and verification workflow
- Customer portal with scoped facility visibility and invitation-based onboarding
- Notification system (in-app + email) driven by an admin-controlled matrix
- Reports — on-demand PDF/CSV/Excel scorecards, scheduled email digests, Issues Aging, SLA Compliance, Follow-up Closure Rate, and per-facility Customer PDF Summary
- Audit trail — immutable log of every create/update/delete action
- Support chat — Groq AI chatbot for customers with preset FAQ chips; escalation to admin via ticketing system; customers can view and reply to their own tickets; admins manage tickets at
/support/admin/tickets - Mobile API — JWT-authenticated REST layer for the iPad native app
- iPad native app — SwiftUI + SwiftData offline-first inspection tool (Phase A + B + C complete)
The application is actively deployed in production and maintained by a single developer/administrator.

Note: `app/routes/broadcast.py` + `app/models/broadcast.py` (admin broadcasts) and
`app/routes/devices.py` (admin device registry, reads `api_device_tokens`) are also
part of the tree — see §7. Device registration on the API side lives in
`app/api/auth.py` only (there is no `app/api/devices.py`).
4. Environment & Configuration
Required Environment Variables
| Variable | Notes |
|---|---|
SECRET_KEY |
Flask secret — no fallback; startup fails if absent |
DATABASE_URL |
e.g. mysql+pymysql://user:pass@localhost/jqc |
MAIL_SERVER |
SMTP hostname |
MAIL_USERNAME |
SMTP login |
MAIL_PASSWORD |
SMTP password |
MAIL_PORT |
465 (SSL) or 587 (STARTTLS) — auto-selects flags |
APP_BASE_URL |
Full URL for email links |
MAIL_DEFAULT_SENDER |
From address |
DIGEST_SECRET |
Authenticates all cron endpoints |
REDIS_URL |
Optional. When set, Flask-Limiter uses Redis for shared rate-limit counters across Gunicorn workers. |
GROQ_API_KEY |
Optional. When set, enables the AI chatbot at /support/chat. Absent → chat input disabled; customers see a "Submit to Support" fallback only. |
GROQ_MODEL |
Optional. Groq model ID. Defaults to llama-3.3-70b-versatile. |
Email SSL Auto-Detection
MAIL_USE_SSL = _mail_port == 465
MAIL_USE_TLS = not MAIL_USE_SSL
Critical: Never set both to True — Flask-Mail breaks silently.

5. Database Models
User
users: id, username (unique, indexed), full_name, email (unique, indexed),
password_hash, role (ENUM), created_at, active,
password_set, set_password_token (indexed), set_password_token_expires
Role ENUM: admin, director, inspector, project_manager, customer
Key property: display_name → full_name.strip() or falls back to username.
Facility / Area
facilities: id, name, address, contact_person, contact_phone, active, project_id (FK),
public_token VARCHAR(48) unique ← Phase 34 (QR landing page)
areas: id, facility_id (FK), name, area_type,
public_token VARCHAR(48) unique ← Phase 39 (per-area QR landing page)
public_token (Phase 34): unguessable per-facility token encoded in the facility's QR code. The QR points at /f/<public_token> — a login-free occupant summary page. Facility.generate_public_token() / ensure_public_token() mint one on demand; new facilities get one at creation, existing rows were backfilled by phase34. Rotating the token (regenerating it) invalidates any printed QR — intentional, for when a code is compromised.
Area.public_token (Phase 39): the same pattern applied per area. The QR points at /f/area/<public_token> — a login-free occupant summary scoped to that single area (its own avg score / inspection count / open-issue count / trend / recent inspection dates), with a "report a problem" form that files the issue with area_id set. Area.generate_public_token() / ensure_public_token() mirror the Facility methods; new areas get a token at creation, existing rows backfilled by phase39. Both public pages obey rule 74 (aggregate + dates only — never checklist names, per-inspection scores, or severity/SLA). Routing: /f/area/<token> and /f/<token> do not collide (tokens are single-segment; area is a literal first segment).
area_type choices: restroom, lobby, hallway, office, kitchen, storage, floor, outdoor, other
Project / CustomerAssignment
projects: id, name, description, project_manager_id, active, created_at
customer_assignments: id, user_id, project_id, facility_id (nullable)
UniqueConstraint(user_id, project_id, facility_id)
inspector_assignments: id, user_id, project_id, created_at
UniqueConstraint(user_id, project_id, name='uq_inspector_project')
ForeignKey user_id → users(id) ON DELETE CASCADE
ForeignKey project_id → projects(id) ON DELETE CASCADE
Inspection
inspections: id, template_id, facility_id, area_id, inspector_id, inspection_date,
overall_score, status (in_progress/completed/flagged), notes, form_data (JSON),
completed_at, parent_inspection_id (self-FK), follow_up_required, follow_up_note,
mobile_local_id VARCHAR(64) nullable indexed ← Phase B
submit_latitude DECIMAL(10,7) nullable ← Phase 25
submit_longitude DECIMAL(10,7) nullable ← Phase 25
mobile_local_id: UUID string generated on the iPad. Used for idempotency — if a submission arrives twice (network retry), the server returns the existing record without creating a duplicate. Set NULL for all web-created inspections.
Score rule: Items with score = 0 mean "unanswered" — excluded from calculation entirely.
Issue
issues: id, inspection_id (nullable), area_id, facility_id (nullable), severity (low/medium/high/critical),
description, photo_path VARCHAR(255), status (open/in_progress/resolved/pending_verification),
assigned_to, reported_by (nullable FK → users, SET NULL on delete),
reported_at, resolved_at, result_notes, result_photos (JSON),
mobile_photo_paths (JSON), ← Phase 19
verified_by, verified_at, verification_note, sla_notified,
mobile_local_id VARCHAR(64) nullable indexed, ← Phase B
vendor_name VARCHAR(100) nullable, ← Phase 26
vendor_contact VARCHAR(200) nullable, ← Phase 26
vendor_notes TEXT nullable, ← Phase 26
handler_type ENUM('internal','facility','vendor') NOT NULL DEFAULT 'internal', ← Phase 35
facility_handler_name VARCHAR(100) nullable, ← Phase 35
facility_handler_contact VARCHAR(200) nullable, ← Phase 35
facility_handler_notes TEXT nullable ← Phase 35
Handler (handler_type, Phase 35) — who is doing the work:
| Value | Meaning | Detail fields | assigned_to role |
|---|---|---|---|
internal (default) |
Janitorial Staff (our crew) | — (the assignee IS the handler) | the handler |
facility |
The facility's own staff | facility_handler_name/contact/notes (free text) |
internal follow-up owner |
vendor |
External contractor | vendor_name/contact/notes (Phase 26) |
internal follow-up owner |
Display labels are perspective-neutral (they read the same for staff and customers) with a descriptor line under the selector and a tooltip on badges: internal → "Janitorial Staff" ("Our janitorial crew handles it."), facility → "Facility Staff" ("The facility's own on-site staff handle it."), vendor → "External Vendor" ("An outside contractor handles it."). Labels/descriptions live in Issue.HANDLER_LABELS / HANDLER_DESCRIPTIONS, the WTForms handler_type choices, and the HANDLER_DESC JS map in both issue templates — keep these in sync. Do not use viewer-relative words like "Our"/"Your" for the stored categories.
assigned_to (a JQC User) is always available: it is the handler for internal, and the internal follow-up owner (e.g. the inspector who verifies/updates) for facility/vendor. Settable in two places, both with a "Handled By" selector that reveals the facility or vendor sub-fields via JS:
- Log New Issue form (
issues/form.html) — at creation, for non-customer staff. Customer-created issues stayinternal(the handler UI is hidden for them, same asassigned_to). - Update Issue panel on the issue detail page (
issues/view.html) — triage after creation.
Triage of handler_type + facility/vendor detail fields on the update panel is admin/director/project_manager only (same gate as vendor fields); on the create form it follows the form's own access (admin/director create for staff). assigned_to editing on update remains admin/director. Issue list is filterable by ?handler_type= and shows a Facility/Vendor badge. Issue.handler_label gives the display string. Not yet exposed in the mobile API.
Photo columns — three distinct fields with different semantics:
| Column | Type | Populated by | Displayed as |
|---|---|---|---|
photo_path |
VARCHAR(255) |
Web form upload OR first iPad photo | "Photo Evidence" (primary) |
mobile_photo_paths |
JSON (list[str]) |
iPad PATCH /issues/<id>/photos — extra evidence photos |
"Photo Evidence" (additional) |
result_photos |
JSON (list[str]) |
Web update form file upload — resolution photos | "Resolution Details" |
Rule: Never write iPad evidence photos into result_photos. They belong in mobile_photo_paths so they appear under "Photo Evidence" on the web, not "Resolution Details".
reported_by: Added in phase18. Set at creation time to the user who filed the issue. Nullable for backward compatibility. Used by GET /api/v1/issues to return issues the inspector created but hasn't been assigned yet.
Notification / NotificationPreference
notifications: id, user_id, title, body, link, is_read, created_at, issue_id,
inspection_id, event_type VARCHAR(50) NULL, digest_pending
notification_preferences: id, user_id, event_type, email_enabled, digest_mode, digest_frequency
IssueComment
issue_comments: id, issue_id (FK), user_id (FK), body, created_at,
status_at_time, is_customer_visible (BOOLEAN, default False) ← Phase 22
is_customer_visible: Staff comments are hidden from customers by default (False). Staff can tick "Share with customer" at post time to set True. Customer-authored comments are always stored as True. Customers see only is_customer_visible=True comments; staff see all.
FacilityScoreAlert
facility_score_alerts: id, facility_id (FK→facilities CASCADE), sent_at DATETIME,
current_avg DECIMAL(5,2), prior_avg DECIMAL(5,2), delta DECIMAL(5,2)
INDEX ix_fsa_facility_sent (facility_id, sent_at)
Records each score-trend alert dispatched for a facility. send_score_alerts() queries this table to skip re-alerting a facility within the last 24 hours, preventing notification storms on persistent score drops.
SupportTicket / SupportTicketReply
support_tickets: id, customer_id (FK→users SET NULL), facility_id (FK→facilities SET NULL),
subject VARCHAR(200), body TEXT, status VARCHAR(20) DEFAULT 'open',
created_at DATETIME
status values: open / answered / closed
support_ticket_replies: id, ticket_id (FK→support_tickets CASCADE), user_id (FK→users SET NULL),
body TEXT, created_at DATETIME
SupportChatSession / SupportChatMessage (Phase 37)
support_chat_sessions: id, customer_id (FK→users CASCADE, indexed),
created_at, updated_at (indexed)
support_chat_messages: id, session_id (FK→support_chat_sessions CASCADE, indexed),
role ('user'|'assistant'), content TEXT, created_at
Persists the customer AI support chat. chat_message() writes both the user turn and the assistant reply into the session (creating one lazily on the first message; session.updated_at bumped each turn). chat() reloads the customer's most recent session into the chat window for continuity (unless ?new=1). Read-only history views exist for the customer (/support/my-conversations) and staff (/support/admin/conversations). SupportChatSession.preview = first user message; .message_count for list views. See §18 "Support Chat".
SupportKnowledge (Phase 38)
support_knowledge: id, title VARCHAR(200), content TEXT, active BOOL,
sort_order INT, created_by (FK→users SET NULL), created_at, updated_at
Admin-curated knowledge entries that "train" the AI chatbot without code changes. _system_prompt_with_kb() in routes/support.py appends every active entry (ordered by sort_order, id) to the base _SYSTEM_PROMPT on each chat request, soft-capped at _KB_MAX_CHARS (6000). Managed by admin/director at /support/admin/knowledge (list/new/edit/delete). The base _SYSTEM_PROMPT is a comprehensive, customer-scoped description of the app; the KB is the incremental, non-dev-editable layer on top. The chatbot is Groq/Llama (GROQ_MODEL, default llama-3.3-70b-versatile) — not fine-tuned; all "knowledge" is prompt context.
Flow:
- Customer submits ticket via chat page modal → status
open→ admins notified (in-app + email) - Admin replies → status auto-advances to
answered→ customer notified (in-app + email, link to/support/my-tickets/<id>) - Customer adds follow-up → status reverts to
open→ admins notified again - Admin can manually set:
open/answered/closed - Closed tickets cannot receive new replies from customers
NotificationMatrix
notification_matrix: id, event_type, role_key, enabled, custom_emails (JSON)
UniqueConstraint(event_type, role_key)
AuditLog
audit_logs: id, user_id (nullable), username (snapshot), user_role (snapshot),
action, entity_type, entity_id, entity_label, details, created_at (indexed), ip_address
RefreshToken / DeviceToken
api_refresh_tokens: id, user_id, token_hash (SHA-256, unique), device_id, device_name,
created_at, expires_at, revoked
api_device_tokens: id, user_id, device_id, apns_token, device_name, app_version,
ios_version, registered_at, last_seen_at ← ios_version + last_seen_at added phase32
UniqueConstraint(user_id, device_id)
api_device_tokens is the single source of truth for device tracking. It is upserted by POST /api/v1/devices/register (in app/api/auth.py) on every app foreground and read by the admin Devices page (/admin/devices). The earlier device_registrations table / DeviceRegistration model was removed — see §17 phase30–32.
Broadcast
broadcasts: id, title VARCHAR(255), body TEXT, target_roles (JSON list of role strings),
sent_by_id (FK→users SET NULL), sent_at DATETIME, recipient_count INT
Admin-authored broadcast messages. Sending a broadcast fans out one Notification row per targeted user; the iPad picks them up through its existing GET /api/v1/notifications?since=... poll — no dedicated broadcast API endpoint exists. recipient_count snapshots how many notifications were created. Managed at /admin/broadcast (see §7 broadcast blueprint).
ContractNotificationRecipient
contract_notification_recipients:
id, project_id (FK→projects CASCADE, indexed),
user_id (FK→users CASCADE, nullable, indexed), -- staff-user recipient
email VARCHAR(200) nullable, -- external email recipient
event_types TEXT (JSON list of event_type keys), created_at
Per-contract additional notification recipients. Each row is ONE extra recipient attached to a Contract who is notified — for the event_types they subscribe to — whenever those events fire within that contract's facilities, in addition to the global NotificationMatrix routing. Exactly one of user_id / email is set (enforced in the route, not the DB):
user_idset → existing staff user → in-app notification + emailemailset → free-form external address → email only
event_types is a JSON list of MATRIX_EVENTS keys. A recipient fires only when the event is in its list. Managed admin-only on the Contract detail page (/projects/<id>) via add_notify_recipient / remove_notify_recipient. Dispatch is resolved centrally in notify_by_matrix() — see §11.
ScheduledInspection
scheduled_inspections:
id, facility_id (FK→facilities CASCADE), template_id (FK→inspection_templates CASCADE),
inspector_id (FK→users SET NULL), frequency ENUM('once','daily','weekly','monthly'),
next_due_date DATE, active BOOL, notes TEXT, created_by, created_at,
last_completed_at DATETIME, advance_notified BOOL, due_notified BOOL, overdue_notified BOOL
inspections.scheduled_inspection_id FK→scheduled_inspections SET NULL ← Phase 36
A plan, not an inspection. Names a facility + template + assigned inspector + next_due_date. Lifecycle:
- The assigned inspector (or a manager) clicks Start →
scheduled_inspections.startcreates a normalin_progressInspection withscheduled_inspection_idset, then redirects to the execute flow. - On completion (execute route, status →
completed),ScheduledInspection.fulfill()runs in the same atomic commit:once→active=False; recurring →next_due_daterolls forward past today via_add_interval()and the three*_notifiedflags reset. - Assignment notification (immediate): on create, the assigned inspector gets an in-app + email "assigned to you" notification; on edit, only when the inspector actually changes (a "reassigned to you" notification to the new assignee). Via
_notify_assignee()in the blueprint usingevent_type=EVENT_SCHEDULED_INSPECTION. - Reminders are dispatched by the cron endpoint (see §11): advance (1 day before) + due-date to the inspector, overdue to admin/director — each fires at most once per occurrence via the
*_notifiedflags. Usesnotify()withevent_type=EVENT_SCHEDULED_INSPECTION. - Dashboard shows an upcoming (next 7 days) / overdue panel for non-customers (inspectors see only their own).
Management (/scheduled-inspections/new|edit|delete) is @project_manager_required; Start is the assigned inspector or a manager; inspectors' list/dashboard views are scoped to their own inspector_id.

8. Utility Modules
time_utils.py
now_eastern() — always use this, never datetime.utcnow().
audit.py
log_action(action, entity_type, entity_id, entity_label, details) — call after db.session.commit(). This function calls db.session.commit() internally. Calling it before the primary commit will prematurely persist any dirty ORM state in the session.
mail_utils.py
branded_sender(base_url=None) — returns a Flask-Mail (display_name, address) sender tuple whose identity tracks the current host, used by the customer invite email. Two things vary independently:
- Display name (always applied, zero DNS): per-domain brand from
BRAND_NAMES(fallbackDEFAULT_BRAND_NAME), e.g."Gov Services QC". - From address (gated): the authenticated local part (
jqc.noreply) with the host's registrable domain — but only for the authenticated sender's own domain or a domain listed inSENDER_AUTHORIZED_DOMAINS. Every other domain keeps the authenticatedMAIL_DEFAULT_SENDERaddress so it still passes SPF/DMARC and delivers.
So with no DNS work an invite from jqc.govservicesinc.com sends From: "Gov Services QC" <jqc.noreply@ltservicesinc.com> (branded name, deliverable address). After that domain's SPF include: + DKIM are live, add it to SENDER_AUTHORIZED_DOMAINS and it upgrades to <jqc.noreply@govservicesinc.com> — no code change. Falls back to the bare authenticated sender string for unparseable hosts (localhost, empty). Edit BRAND_NAMES / SENDER_AUTHORIZED_DOMAINS as brands and DNS come online. See rule 64.
scope.py
get_customer_scope(user) — returns list[int] facility IDs for customers, None for non-customers.
get_inspector_scope(user) — returns list[int] facility IDs for inspectors (empty list = no assignments = no access), None for non-inspectors. Derived from InspectorAssignment rows → project → active facilities.
forms.py
All WTForms classes. AreaForm.area_type includes floor. UserForm excludes customer role.
notifications.py
notify(), notify_by_matrix(), notify_customers_for_facility() — all email sent in background thread. notify() stores event_type on the Notification record (phase17+). flag_followup route calls notify() for the original inspector.
sla.py
sla_status(issue) → 'ok' | 'at_risk' | 'breached' | None (resolved).
pdf_export.py
ReportLab-based. 12-column grid must be preserved — never collapse in PDF views.
Public functions:
generate_inspection_pdf(inspection, form_fields, form_data, issues, static_folder)— per-inspection PDFgenerate_issues_list_pdf(issues, filter_summary)— landscape issues list PDF (from issues list export)generate_inspections_list_pdf(inspections, filter_summary)— landscape inspections list PDFgenerate_facility_summary_pdf(facility, days, start, now, total_inspections, avg_score, area_scores, open_issues, resolved_count)— customer-facing one-page facility summary PDF (Phase R4)
_build_styles() registered style names: ReportTitle, ReportSub, SectionHead, FieldLabel, FieldValue, MetaLabel, MetaValue, IssueDesc, FooterStyle, SummaryTitle, ReportSubtitle, Meta, ScoreValue, ScoreLabel, SectionHeader, TableHeader, TableCell
The last eight styles (SummaryTitle through TableCell) were added for the facility summary PDF and are available for any future customer-facing PDF functions.
9. Mobile API (Phase 7 / Phase A–E)
CSRF Exemption Pattern — Critical
csrf.exempt(api_bp) does NOT cascade to sub-blueprints. Each child blueprint must be exempted individually in app/__init__.py. The new api_issues blueprint (including its PATCH /issues/<id>/photos route) inherits the exemption already applied to _api_issues_bp. Every new blueprint must add its own csrf.exempt() line before register_api(app).
Auth Flow
POST /api/v1/auth/login→ access token (60 min JWT) + refresh token (30 day opaque hex)- Bearer token on every request
POST /api/v1/auth/refresh→ token rotation (old revoked, new issued)POST /api/v1/auth/logout→ revokes refresh token
Phase A Endpoints
| Endpoint | Auth | Description |
|---|---|---|
GET /api/v1/facilities |
jwt_required | All active facilities scoped to user |

|---|---|---|
PATCH /api/v1/issues/<id>/photos |
jwt_required | Attach extra evidence photos to an issue. Accepts { "result_photos": ["uploads/..."] }. Stores in mobile_photo_paths (NOT result_photos). Idempotent — merges with existing paths, never overwrites. |
Phase B (Stats) Endpoint
| Endpoint | Auth | Description |
|---|---|---|

jwt_required | All comments oldest-first. Returns: id, issue_id, author_name, author_role, status_at_time, body, created_at. Inspectors limited to contracted facilities. |
POST /api/v1/issues/<id>/comments |
jwt_required | Add a comment. Body: { "body": "..." }. Fires notify_by_matrix('issue_comment'). Calls log_action() after commit. |
Phase E Additions to Existing Endpoints
_issue_payload() in issues.py now returns area_name and assigned_to_name (both nullable). These populate LocalIssue.areaNameCache and LocalIssue.assignedToName on the iPad after every pullAssignedIssues(). refreshStatusFromServer() also refreshes them on demand.
stats.py now returns severity_breakdown dict alongside the existing KPIs. Derived from the already-loaded open_issues_all list — zero extra DB queries.
Issue API — _issue_payload() fields
{
'id', 'status', 'severity', 'description', 'assigned_to',
'facility_id', 'facility_name', 'reported_at', 'resolved_at',
'mobile_local_id',
'photo_path', # primary evidence photo (first iPad photo or web upload)
'mobile_photo_paths', # extra evidence photos from iPad (list)
'result_photos', # resolution photos added via web form (list)
# Phase A additions:
'result_notes', # resolution notes entered by web staff
'verified_at', # ISO 8601 datetime when fix was verified (nullable)
'verification_note', # note from the verifier (nullable)
'reported_by_name', # display_name of User who filed the issue (nullable)
# Phase E additions:
'area_name', # name of the Area the issue was flagged in (nullable)
'assigned_to_name', # display_name of currently assigned User (nullable)
}
iOS reads photo_path + mobile_photo_paths into photoServerPaths. It does NOT read result_photos — those are web-only resolution photos.
Issue API Scope Rules
- Inspector:
GET /issuesreturns issues whereassigned_to == current_user.idORreported_by == current_user.id. - Admin / Director / Project Manager:
GET /issuesreturns all non-resolved issues (default) or filtered by?status=. GET /issues/<id>andPATCH /issues/<id>/statusandPATCH /issues/<id>/photosall enforce the same combined inspector check.
Photo Upload Flow (multi-photo issues)
1. iPad calls POST /api/v1/photos/upload × N → gets N server_path strings
2. iPad calls POST /api/v1/issues → sends photo_path = paths[0]
result_photos = paths[1:] (stored in mobile_photo_paths)
3. iPad calls PATCH /api/v1/issues/<id>/photos → sends result_photos = paths[1:]
(PATCH is belt-and-suspenders for race safety)
Web template shows photo_path + mobile_photo_paths together under "Photo Evidence". result_photos (resolution photos from web form) appears under "Resolution Details".
Facility deduplication
pullReferenceData() deduplicates the /api/v1/facilities response by id before upserting. The server may return the same facility ID more than once (one row per contract assignment). Without deduplication, the same building appears twice in every picker. The dedup uses a seenFacilityIds = Set<Int>() filter on the iOS side AND the upsert map (facilityMap) on the server side.
Idempotency Pattern
All Phase B write endpoints accept mobile_local_id (UUID string from device). On receipt, check for existing record and return { 'duplicate': True } without inserting. Web-created records have mobile_local_id = NULL.
Score Calculation (Server-Side)
app/api/inspections.py::_compute_score() mirrors routes/inspections.py::_compute_score_from_form() exactly. Rating value 0 = unanswered → excluded. Returns float 0–100 or None if no scoreable fields.
10. iPad Native App
See the iOS app's own CLAUDE.md for full details. Key integration points:
- App connects to
jqc.ltservicesinc.com(primary) orjqc1.ltservicesinc.com(secondary) — server is user-selectable at login and in Settings. - Server selection is persisted to
UserDefaultsviaServerConfig. Switching server in Settings triggers a logout confirmation alert and clears all server-pulled SwiftData records (serverId != nil) before logout. - All photo evidence from the iPad routes through
mobile_photo_pathson the server — never throughresult_photos.
11. Notification System
Event Constants (app/models/notification.py)
EVENT_ISSUE_ASSIGNED = 'issue_assigned'
EVENT_ISSUE_STATUS = 'issue_status'
EVENT_ISSUE_COMMENT = 'issue_comment'
EVENT_ISSUE_FOLLOW = 'issue_follow_update'
EVENT_INSPECTION_DONE = 'inspection_completed'
EVENT_SLA_ALERT = 'sla_alert'
EVENT_ISSUE_FLAGGED = 'issue_flagged'
EVENT_CUSTOMER_INSPECTION_DONE = 'customer_inspection_completed'
EVENT_CUSTOMER_ISSUE_UPDATED = 'customer_issue_updated'
EVENT_SCORE_ALERT = 'score_alert' ← Phase 27
EVENT_SCHEDULED_INSPECTION = 'scheduled_inspection' ← Phase 36
Per-Contract Additional Recipients (Phase 33)
notify_by_matrix() is the single dispatch point for all broadcast events. After routing to the global matrix roles + global custom emails, it calls _notify_contract_recipients(), which:
- Resolves the owning contract via
_resolve_project_id(facility_id, issue_id, inspection_id)— triesfacility_id, then the issue's facility (orissue.area.facility_id), then the inspection's facility. - Loads
ContractNotificationRecipientrows for that project and notifies each one whoseevent_typescontains the firing event. - Deduplicates against users already notified this dispatch (shared
notifiedset) and emails already sent (sharedsent_emailsset), so a user who is both a matrix role AND a contract recipient gets exactly one notification.
Contract recipients fire regardless of matrix role toggles — they are additive, not gated by the matrix. Staff-user recipients use respect_preferences=False (contract config is authoritative, mirroring matrix broadcasts). Commit is the caller's responsibility, same as the rest of notify_by_matrix().

issue.sla_notified prevents duplicate cron notifications.
13. Audit Trail
- Admin-only at
/audit/— director is excluded - Actions:
CREATE,UPDATE,DELETE,LOGIN,LOGOUT,EXPORT - Mobile API routes call
log_action()for all create/update operations - Immutable — never updated or deleted through the application
14. PDF Export
ReportLab — app/utils/pdf_export.py. 12-column grid must be preserved — do not collapse in print/PDF.
15. Scheduled Reports
Types: summary, facility, issues. Frequencies: daily, weekly, monthly.
Cron: POST /scheduled-reports/run?secret=<DIGEST_SECRET>
16. Rate Limiting
limiter = Limiter(
key_func = get_remote_address,

phase21_performance_indexes
Adds four composite indexes covering the highest-traffic multi-column query patterns: (facility_id, inspection_date) and (inspector_id, inspection_date) and (status, inspection_date) on inspections; (facility_id, status) on issues. All single-column indexes already exist from phase12. Uses INFORMATION_SCHEMA.STATISTICS existence check — safe to re-run.
Deploy order for phase21:
flask db upgrade
sudo systemctl restart gunicorn
phase21_template_active
Adds active boolean column to inspection_templates so templates can be deactivated without deletion. Inactive templates are hidden from the inspection-start form but remain accessible in the template management UI. Uses INFORMATION_SCHEMA column existence check — safe to re-run.
phase23_support_tickets
Creates support_tickets and support_ticket_replies tables. Uses table existence check — safe to re-run.
Deploy order:
flask db upgrade
pip install groq # if not already installed
# Set GROQ_API_KEY in environment / systemd unit
sudo systemctl restart gunicorn
phase24_notify_defaults
Data-only migration. Sets enabled=True for ('issue_created', 'admin') and ('issue_created', 'director') rows in notification_matrix if they already exist. Rows that do not yet exist are seeded at runtime by MATRIX_DEFAULTS. No schema change — no existence check needed, UPDATE on missing rows is a no-op.
phase25_inspection_gps
Adds submit_latitude DECIMAL(10,7) NULL and submit_longitude DECIMAL(10,7) NULL to inspections. Populated at submit time — by browser Geolocation API (web) or CoreLocation (iPad). Null for all existing rows. Uses INFORMATION_SCHEMA column existence check — safe to re-run.
inspections/view.html shows a Google Maps embed (admin/director only) when both columns are non-null.
iPad behaviour: InspectionLocationManager begins acquiring a fix when the submit confirm dialog appears. GPS is captured into LocalInspection.submitLatitude/submitLongitude and sent in the POST /api/v1/inspections body. The PATCH endpoint does not accept GPS — creation-time capture only.
phase26_issue_vendor
Adds three nullable columns to issues:
| Column | Type | Purpose |
|---|---|---|
vendor_name |
VARCHAR(100) |
External contractor or vendor name |
vendor_contact |
VARCHAR(200) |
Phone or email for the vendor |
vendor_notes |
TEXT |
Notes about what the vendor is handling |
Displayed in issues/view.html and editable via IssueForm (form.html). Staff-only — not exposed in mobile API. Uses INFORMATION_SCHEMA existence check — safe to re-run.
phase27_score_alerts
Creates facility_score_alerts table. Used by send_score_alerts() in sla.py for 24-hour deduplication of score-drop notifications. Uses table existence check — safe to re-run.
phase28_fix_inspection_notify
Data-only migration. Resets the notification_matrix rows for ('inspection_completed', 'director'), ('inspection_completed', 'admin'), and ('inspection_completed', 'customer') to enabled=True, matching MATRIX_DEFAULTS. These had been inadvertently disabled (likely via an accidental checkbox save on the matrix page), suppressing inspection-completed notifications from both web and mobile API. No schema change.
phase29_broadcasts
Creates the broadcasts table backing the admin broadcast feature (see §5 Broadcast and §7 broadcast blueprint). Uses table existence check — safe to re-run.
phase30–32_device_registry (consolidation — read as a unit)
These three migrations are the history of a false start in device tracking. Net effect after all three: the app tracks devices exclusively in api_device_tokens (DeviceToken model); the short-lived device_registrations table and its DeviceRegistration model no longer exist.
- phase30_device_registry — created a separate
device_registrationstable (the abandoned approach). - phase31_device_registry — drops
device_registrations(DROP TABLE IF EXISTS). - phase32_device_token_columns — the live path. Adds
ios_version VARCHAR(20)andlast_seen_at DATETIMEtoapi_device_tokens(phase31's ALTERs were recorded-but-never-executed, so phase32 re-applies them viaINFORMATION_SCHEMAexistence checks) and drops the orphaneddevice_registrationstable if still present. Safe to re-run.
The dead DeviceRegistration model, app/api/devices.py endpoint, and api_devices blueprint were removed (July 2026). They defined a second POST /api/v1/devices/register that was shadowed at routing time by the api_auth copy and would have crashed anyway (it queried the dropped device_registrations table). Device registration now has a single implementation: register_device() in app/api/auth.py, writing to api_device_tokens. Do not reintroduce a competing device model or a duplicate register route.
phase33_contract_recipients
Creates the contract_notification_recipients table backing per-contract additional notification recipients (see §5 ContractNotificationRecipient and §11). Uses table existence check — safe to re-run.
Deploy order:
flask db upgrade
sudo systemctl restart gunicorn
phase34_facility_qr
Revision id phase34_facility_qr (file phase34_facility_public_token.py). Adds facilities.public_token VARCHAR(48) (unguessable, unique) and backfills a token for every existing facility in the migration body, then creates the uq_facility_public_token unique index. Backs the public QR landing pages (see §5 Facility.public_token and the Public Facility QR section in §7). Uses INFORMATION_SCHEMA checks — safe to re-run.
Deploy order:
pip install qrcode # new dependency (Pillow already present)
flask db upgrade # adds + backfills public_token
sudo systemctl restart gunicorn
phase35_issue_handler
Revision id phase35_issue_handler (file phase35_issue_handler_type.py). Adds to issues: handler_type ENUM('internal','facility','vendor') NOT NULL DEFAULT 'internal' and facility_handler_name/contact/notes. Backfills existing rows with a non-empty vendor_name to handler_type='vendor'. Separates WHO handles an issue (see §5 Issue + the Handler section). INFORMATION_SCHEMA checks — safe to re-run.
Deploy order:
flask db upgrade
sudo systemctl restart gunicorn
phase36_scheduled_insp
Revision id phase36_scheduled_insp (file phase36_scheduled_inspections.py). Creates scheduled_inspections (planned/recurring inspection assignments) and adds inspections.scheduled_inspection_id (FK → scheduled_inspections, SET NULL) that links a completed inspection back to the schedule that prompted it. See §5 ScheduledInspection and the Scheduled Inspections notes in §7/§11. INFORMATION_SCHEMA checks — safe to re-run.
Deploy order:
flask db upgrade
sudo systemctl restart gunicorn
# Add to cron (reminders — advance/due to inspector, overdue to admin/director):
# */30 * * * * curl -s -X POST https://yourdomain.com/scheduled-inspections/run \
# -d "token=YOUR_DIGEST_SECRET"
phase37_support_chat
Revision id phase37_support_chat. Creates support_chat_sessions + support_chat_messages so the customer AI support-chat is persisted (see §5 and §18 "Support Chat"). Table existence checks — safe to re-run.
Deploy order:
flask db upgrade
sudo systemctl restart gunicorn
phase38_support_knowledge
Revision id phase38_support_knowledge. Creates support_knowledge (admin-curated AI-chat knowledge entries). Active entries are injected into the chatbot system prompt at request time by _system_prompt_with_kb() (soft-capped at _KB_MAX_CHARS). Table existence check — safe to re-run.
Deploy order:
flask db upgrade
sudo systemctl restart gunicorn
phase39_area_public_token
Revision id phase39_area_public_token. Adds areas.public_token VARCHAR(48) (unguessable, unique), backfills a token for every existing area in the migration body, then creates the uq_area_public_token unique index. Backs the per-area public QR landing pages (see §5 Area.public_token and the public / facilities blueprint rows in §7). Mirrors phase34 exactly, one level down (area instead of facility). INFORMATION_SCHEMA checks — safe to re-run. No new dependency (qrcode + Pillow already present from phase34).
Deploy order:
flask db upgrade # adds + backfills areas.public_token
sudo systemctl restart gunicorn
Deploy order for phases 24–32:
flask db upgrade
sudo systemctl restart gunicorn
# Add to cron:
# 0 8 * * * curl -s -X POST https://yourdomain.com/notifications/check-score-trends \
# -d "token=YOUR_DIGEST_SECRET"
phase22_comment_visibility
Adds is_customer_visible BOOLEAN NOT NULL DEFAULT FALSE to issue_comments. Existing comments default to staff-only visibility. Uses INFORMATION_SCHEMA column existence check — safe to re-run.
phase19_issue_mobile_photos
Adds mobile_photo_paths JSON NULL to issues table. Stores extra evidence photos submitted from the iPad at issue-creation time, separate from result_photos (resolution photos) so they appear under "Photo Evidence" on the web. Uses INFORMATION_SCHEMA existence check — safe to re-run.
Deploy order for phase19:
flask db upgrade # add mobile_photo_paths column
sudo systemctl restart gunicorn
MySQL ENUM Change Protocol (3 steps — always follow)
-- 1. Expand
ALTER TABLE users MODIFY COLUMN role ENUM('admin','supervisor','director',...) NOT NULL;
-- 2. Migrate
UPDATE users SET role = 'director' WHERE role = 'supervisor';
-- 3. Contract
ALTER TABLE users MODIFY COLUMN role ENUM('admin','director',...) NOT NULL;
MySQL Compatibility Rules
- Revision ids must be ≤ 32 characters. Alembic's
alembic_version.version_numcolumn isVARCHAR(32). A longerrevision = '...'value passesflask db upgrade's DDL step but fails when Alembic writes the version row (Data too long for column 'version_num'), often leaving the schema changed but the version un-recorded. The filename may be longer (e.g.phase24_issue_created_notify_defaults.py), but therevisionid inside must be short (phase24_notify_defaults). Count before committing a new migration. CREATE INDEX IF NOT EXISTS— not supported on MySQL < 8.0.12. Always useINFORMATION_SCHEMA.STATISTICScheck first.batch_alter_table— SQLite-only workaround; do not use for MySQL migrations.- Migration deploy order: Always run
flask db upgradebefore swappingapp/__init__.pyif the new version imports models that reference the new columns.
Deprecated SQLAlchemy Patterns
# WRONG
Model.query.get(id)
# CORRECT
obj = db.session.get(Model, id)
if obj is None: abort(404)
18. Frontend Conventions
Active Nav Tab
Detected via request.endpoint.startswith('<blueprint>.') in each nav <a> tag.
Admin Nav Dropdown
Admin-only tools (Users, Audit Trail, Notification Matrix, Broadcast, Devices) are consolidated into a single Admin dropdown in base.html (plain text items, no icons, no dividers — matching sibling top-level nav links). The dropdown toggle shows active when any of its endpoints is active (admin_active flag). The separate user-menu dropdown keeps its own dividers — don't replace_all on dropdown-divider across the file.
Display Names
Always use user.display_name in templates — never .username for display purposes.

Forms
- Flask-WTF CSRF auto-applied to all web forms
- Never nest
<form>tags — browsers silently discard inner forms
Real-Time
SSE banned. All "live" updates use polling.
Issue Photo Evidence Display (view.html)
view.html shows photo_path and mobile_photo_paths together under the "Photo Evidence" heading using a d-flex flex-wrap gap-2 grid. result_photos (resolution photos) appear separately under "Resolution Details". Do not merge these sections — they have different semantic meaning.
Contract → Facility Cascade (filter bars and create form)
The Contract selector is always a plain HTML <select> (never a WTForms field). On change it calls GET /inspections/facilities_for_project/<project_id> and replaces the Facility <option> list. When the Contract is cleared it restores the "All Facilities" placeholder. The filter bars auto-narrow the server-side facility dropdown on page load when contract_id is in the query string.
Pages using this pattern: issues/form.html (create), issues/list.html (filter bar), inspections/list.html (filter bar), scheduled_inspections/form.html (create/edit — Contract selector narrows the facility list; selected_project_id restores it on edit and on POST error).
The issues list and inspections list both accept a contract_id query param that filters the DB query to facilities belonging to that contract (facility.project_id == contract_id) and narrows the facility dropdown in the rendered HTML.
Customer role — contract filter scoping: In inspections.index() and issues.index(), the projects list passed to the template is scoped to contracts the customer is assigned to via CustomerAssignment. Non-customer roles still receive all active projects. This prevents customers from seeing contracts they have no assignment to in the Contract filter dropdown.
Customer Dashboard — "Your Facilities" Panel
Rendered in dashboard.html for current_user.role == 'customer'. Uses a Bootstrap card grid instead of a table:
- Grid:
col-12 col-sm-6 col-lg-4— 3 per row on large, 2 on medium, 1 on small. - Collapse (> 9 facilities): First 9 cards are shown; a "Show all N facilities" toggle reveals the rest. Controlled by inline JS (
toggleFacilitiesbutton,VISIBLE = 9constant). - Live search (> 6 facilities): A
#facilitySearchtext input filters.facility-colcards in real time by matching against the card's full text content. The show-more bar hides while a search query is active. - Count badge: The card header always shows the total facility count as a
badge bg-secondary rounded-pill. - The JS block is only emitted when
customer_facilities|length > 9; the search input is only emitted whencustomer_facilities|length > 6.
Issue Comments — Visibility & Authorship
- Comments live in the left column of
issues/view.htmlunder the issue description, rendered as chat bubbles. - Each bubble shows: colored avatar circle (color keyed to
author.id % 7), display name, role badge (Staff / Customer),is_customer_visiblebadge (staff-only view), status-at-time badge, timestamp, and body. - Staff commenting: A hidden checkbox
name="is_customer_visible"in the Add Comment form defaults to unchecked (staff-only). Checking it marks the comment visible to customers. - Customer commenting: Only shown when
can_customer_comment = is_following or issue.reported_by == current_user.id. Customer POST bypassesIssueUpdateForm; the route setsis_customer_visible=Trueunconditionally. - Read filtering:
GET issues/viewpassesfilter_by(is_customer_visible=True)to customers; staff receive all comments.
Inspection List Filters
inspections.index() accepts five additional query params: date_from, date_to (ISO date strings), score_min, score_max (0–100 floats), inspector_id (int). Inspector filter is suppressed when the viewer has the inspector role (they always see their own only). The inspectors variable is passed to the template only for non-inspector roles so the dropdown is conditionally rendered.
Inspection List — PDF Export & Filter State Preservation
GET /inspections/export-list-pdf — same filter logic as index(), passes current filters as filter_summary string to generate_inspections_list_pdf(). Logs ACTION_EXPORT.
Filter state on back-navigation: list.html adds class insp-list-link to every View/Continue button. On click, JS saves window.location.href to sessionStorage['insp_list_back_url']. view.html reads this key on load and updates the back button href so returning from a detail view restores the previous filter state.
Issues List — ID Filter, Date Filter & PDF Export
issues.index() accepts additional query params: issue_id (exact match on Issue.id), date_from, date_to (ISO date strings applied to Issue.reported_at; date_to expanded to 23:59:59), handler_type (internal/facility/vendor), and unassigned (truthy → Issue.assigned_to IS NULL). handler_type and unassigned are both threaded through the pagination links and shared with export_list_pdf().
GET /issues/export-list-pdf — same scope + filter logic as index(), applies SLA post-filter for ?sla= param (SLA is computed in Python, not stored). Calls generate_issues_list_pdf().
Both index() and export_list_pdf() carry date_from / date_to in pagination links and the unfollow-next URL.
Inspector Performance — Excel Export
GET /reports/export/inspector-performance generates a .xlsx with two sheets:
- Performance Summary — all inspector KPIs, color-coded cells, totals row
- Inspection Detail — individual inspection records for the period
Accepts start, end, inspector_id query params. Logs an EXPORT audit action. Uses openpyxl.
Dashboard — Grouped Sections
The dashboard cards are organised into two labelled sections separated by a divider rule:
Inspections section (all roles see first 2; staff see all 4):
- Today's Inspections — links to
inspections.indexfiltered by today - Submitted Today — links to
inspections.indexwithstatus=completed+ today's date - Stale In-Progress — inspections with
status=in_progressANDinspection_date < now - 24h; links toinspections.index?status=in_progress - Pending Follow-ups — inspections with
follow_up_required=True; links toinspections.index?status=follow_up
Issues section (customers see first 3; staff see all 5):
- Open Issues — split into THREE cards (all roles), one per handler from
handler_breakdown: Open · Janitorial (handler_type=internal, bg-primary), Open · Facility Staff (handler_type=facility, bg-info), Open · Vendor (handler_type=vendor, bg-warning). Each is a full clickable card linking toissues.index?status=open&handler_type=.... (The single total Open-Issues card with severity C/H/M/L badges was replaced by these three;severity_breakdownis still passed but no longer rendered on the dashboard.) - Issues Opened Today —
date_from=today&date_to=today, with a compact "Handled by" chip split fromopened_today_handler. - Resolved Today —
status=resolved+ today's date range - Pending Verification —
status=pending_verification - Unassigned Open —
status=open&unassigned=1, with a compact "Handled by" chip split fromunassigned_handler.
"Handled by" splits (phase35+): the three Open-Issue cards are dedicated cards; cards 2 and 5 use the compact handler_chips(bd, base) Jinja macro at the top of dashboard.html — full-text chips ("Janitorial N / Facility N / Vendor N") linking to issues.index with the card's own filter (base) plus handler_type=. All breakdowns come from _handler_split(list) over already-loaded issue lists (open_issues_all, opened_today_all, unassigned_all) — no extra queries. Cards with inner links are not wrapped in an outer anchor (nested <a> is invalid). issues.index gained an unassigned=1 filter (Issue.assigned_to.is_(None)), threaded through the list pagination links, so the Unassigned card and its chips link precisely.
Each card has a subtitle line (or the handler split) explaining what it counts. Section dividers use d-flex align-items-center gap-2 with a <div style="flex:1;height:1px;background:#e2e8f0;"> rule.
Inspector Activity table follows the cards for admin/director/PM: all active inspectors, today's completed inspection count per inspector, progress bar scaled to max_count. Green row highlight if count > 0.
Reports — Navigation & New Pages
The Reports main-nav item is positioned second (right after Dashboard). Scheduled Reports was removed from the main nav and is now a sub-nav tab inside Reports (visible to admin/director/PM).
All report pages include {% include 'reports/_subnav.html' %} as the first element inside {% block content %}. The sub-nav tab visibility is role-gated:
| Tab | Roles |
|---|---|
| Overview & Trends | All |
| Issues Aging | All |
| SLA Compliance | All |
| Follow-up Closure | admin, director, project_manager |
| Inspector Performance | admin, director |
| Scheduled Reports | admin, director, project_manager |
Reports — Overview & Trends: "Avg Score by Facility" Contract filter
The Avg Score by Facility card (chart) and the Facility Score Comparison table on reports/index.html share a Contract <select> (#scoreContractFilter) in the chart card header. It is client-side only: reports.index() attaches project_id + contract name to each facility_scores row and passes score_contracts (distinct (project_id, name) present, 0/"No Contract" for unassigned). Selecting a contract filters both the Chart.js bars (renderFacilityChart(pid) mutates the existing chart) and the table rows (.facility-score-row[data-project-id]); default "All Contracts" shows everything. It does not reload the page or affect the top KPIs — only this section. Contracts shown are already role-scoped (customers/inspectors see only theirs).
Reports — Phase R1: Issues Aging (/reports/issues-aging)
Loads all non-resolved issues scoped by role, groups into five age buckets (<24h, 1–3 days, 3–7 days, 1–4 weeks, >4 weeks). SLA status computed per-issue via sla_status(). Filters: severity, facility (both applied in Python after the main query to avoid double-outerjoin conflicts with customer scope).
Excel export: GET /reports/export/issues-aging — one sheet, color-coded severity and SLA columns.
Helper: _load_open_issues_scoped(customer_facility_ids, severity_filter, facility_id_filter) — extracted so both the HTML route and the Excel export share identical query logic.
Reports — Phase R2: SLA Compliance (/reports/sla-compliance)
Loads resolved issues in the date range, computes within_sla() per issue (compares elapsed hours to SLA_HOURS[severity]). Produces:
overall_pct— org/scope-wide compliance %by_severity— dict withtotal,met,pct,sla_hoursper severity tierby_facility— list sorted by compliance % descending
Helper: _sla_within(issue) — used by both the HTML route and the Excel export.
Excel export: GET /reports/export/sla-compliance — 2 sheets: By Severity (with totals row) and By Facility.
Reports — Phase R3: Follow-up Closure (/reports/followup-closure)
@supervisor_required. Loads inspections with follow_up_required=True in date range. Determines which have been re-inspected via a separate SELECT parent_inspection_id FROM inspections WHERE parent_inspection_id IN (...) query — avoids iterating the dynamic follow_ups relationship.
Annotates each inspection with insp._has_followup = insp.id in followed_up_ids (transient Python attribute, not an ORM column).
Excel export: GET /reports/export/followup-closure — one sheet with color-coded "Followed Up?" column (green/red).
Reports — Phase R4: Customer Facility PDF Summary
GET /reports/facility/<id>/summary-pdf — available to all roles with facility access (customer scope enforced). Accepts days param (30/60/90/180/365; default 90). Calls generate_facility_summary_pdf() from pdf_export.py. Downloads directly as a PDF attachment.
A PDF Summary button was added to reports/scorecard.html alongside the existing Full Report and period selector buttons.
Support Chat — Customer UX
GET /support/chat — customer only. Renders:
- Greeting message with
current_user.display_name(injected viavar userName = {{ current_user.display_name | tojson }}— usetojsonnot inline interpolation to prevent XSS/quote breaks). - FAQ quick-reply chips: text stored in
data-faq="..."HTML attribute (HTML-escaped with| e), read in JS viabtn.dataset.faq. Never use| tojsonin anonclick=""attribute — it emits double-quoted JSON inside a double-quoted attribute, breaking HTML parsing and truncating the<script>tag. The FAQ section stays visible for the whole session (phase37) — it is NOT hidden after the first message, and chips are not disabled after clicking (reusable throughout). - Chat history kept client-side in
let history = [], sent with each AJAXPOST /support/chat/message. Server caps at last 20 turns. - Persistence (phase37): conversations are saved to
support_chat_sessions/support_chat_messages. The page reloads the customer's most recent session into the window (continuity) unless?new=1.let sessionId(seeded fromchat_session_id) is sent with each message and updated from the response; the server persists both turns. Header buttons: History (/support/my-conversations) and New (/support/chat?new=1). Staff can review any customer's chats read-only at/support/admin/conversations. Both detail views{% include 'support/_transcript.html' %}. - If
GROQ_API_KEYis absent, input is disabled and a fallback "Submit to Support" link is shown (the reply is still persisted). - "Submit to Support" modal POSTs to
POST /support/tickets; subject pre-filled from last user message in history.
Inspection Execute Page — UX Patterns
- Photo upload-on-select:
uploadPhotoField(input)fires immediately on<input type="file">change. XHR toPOST /<id>/upload-photo. On success, the server path is written to<input type="hidden" id="field_<fid>_server_path">and a<img id="thumb_<fid>">is shown. - Flag-issue as offcanvas:
#flagIssuePanelBootstrap offcanvas contains the flag-issue form. On submit,saveDraft()fires first, then the form is sent viafetch()FormData, then the page reloads. Never navigates away — photos are never lost. - Auto-save draft:
setInterval(autoSave, 60000)calls the save-draft endpoint every 60 s.#autoSaveStatusin the footer shows the last-saved timestamp. - Progress indicator: Counts answered non-zero rating fields vs. total; updates
#progressLabelin the footer on every change. - Scroll restore:
window.scrollYsaved tosessionStorageonbeforeunload; restored onload.

ProxyFix (reverse-proxy awareness)
create_app() wraps app.wsgi_app in werkzeug.middleware.proxy_fix.ProxyFix(x_for=1, x_proto=1, x_host=1). Nginx terminates TLS and forwards over loopback, so without this every request's remote_addr is 127.0.0.1. That would collapse all Flask-Limiter keys into one shared bucket (rate limits become global instead of per-client) and make url_for(_external=True) emit http:// links. x_for=1 trusts exactly one proxy hop (our own Nginx) — do not increase it unless another trusted proxy is added in front, or clients can spoof X-Forwarded-For and defeat rate limiting.

20. Known Constraints & Hard Rules
| # | Rule | Rationale |
|---|---|---|
| 1 | No SSE | Exhausted Gunicorn sync worker pool |
| 2 | now_eastern() always |
utcnow() caused incorrect SLA cutoffs |
| 3 | 3-step MySQL ENUM changes | Skipping causes data loss |
| 4 | Port 465 → SSL; 587 → STARTTLS | Both True breaks Flask-Mail |
| 5 | csrf.exempt() on each child blueprint individually |
csrf.exempt(api_bp) does NOT cascade; Flask-WTF checks leaf blueprint object only |
| 6 | supervisor_required name preserved |
Renaming would touch 30+ route decorators |
| 7 | Score 0 = unanswered | Excluded from calculation — not the same as scoring zero |
| 8 | 12-column grid in PDF | Must not collapse in print/PDF |
| 9 | No nested <form> tags |
Browsers silently discard inner forms |
| 10 | log_action() after db.session.commit() |
Entity ID must exist before audit capture |
| 11 | db.session.get(Model, id) not Model.query.get(id) |
SQLAlchemy 2.x deprecation |
| 12 | filter() before limit() |
SQLAlchemy ordering requirement |
| 13 | Bulk queries in customer list | Per-customer loops cause N+1 |
| 14 | Email in background thread | Never block HTTP response |
| 15 | Open-redirect guards | safe_redirect_url() in app/utils/decorators.py |
| 16 | CREATE INDEX IF NOT EXISTS not on MySQL < 8.0.12 |
Use INFORMATION_SCHEMA.STATISTICS check |
| 17 | batch_alter_table is SQLite-only |
Use direct ALTER TABLE for MySQL migrations |
| 18 | Set REDIS_URL in production |
memory:// is per-process; Gunicorn needs Redis for accurate shared counters |
| 19 | "Project" → "Contract" is UI-only | Backend identifiers unchanged |
| 20 | display_name not username in templates |
Respects full_name; username is login identity only |
| 21 | mobile_local_id idempotency on all mobile write endpoints |
Network retries must not create duplicate records |
| 22 | Photo upload before inspection/issue submission | Server path must be known before the parent record is created |
| 23 | Migration deploy before new app/__init__.py |
New init imports models referencing new columns; columns must exist first |
| 24–29 | (iOS-specific — see iOS CLAUDE.md) | |
| 30 | Do NOT add an explicit Issue.area relationship |
Area.issues declares backref='area', supplying Issue.area automatically. A second declaration raises ConflictingBackreferences at startup. |
| 31 | Do not sync an issue when its parent LocalInspection.syncStatus == "failed" |
Submitting without inspection_id creates orphaned server records |
| 32 | f-string fallback strings must use double-quotes inside single-quoted f-strings | Python 3.11 raises SyntaxError on nested same-delimiter quotes |
| 33–38 | (field ID casting, photo sentinel, notify event_type, follow-up, OperationalError) | See prior rule entries |
| 39 | Inspector issue scope: assigned OR reported — web and API must match | issues.index(), issues.view(), and all API issue endpoints (GET /issues, GET /issues/<id>, PATCH /issues/<id>/status, PATCH /issues/<id>/photos) enforce assigned_to == user.id OR reported_by == user.id for the inspector role |
| 40 | _issue_payload() must return all documented fields |
iPad reads photo_path + mobile_photo_paths into photoServerPaths. Phase A–E added result_notes, verified_at, verification_note, reported_by_name, area_name, assigned_to_name. Omitting any field silently breaks the corresponding iPad display. |
| 41 | log_action() commits internally — always call after db.session.commit() |
audit.py calls db.session.commit() to write the AuditLog row |
| 42 | ~Inspection.follow_ups.any() not == None for dynamic relationships |
follow_ups is lazy='dynamic'; use ~.any() which emits NOT EXISTS |
| 43 | issues.index() outerjoin must precede all filters |
Both customer-scope and facility_filter blocks reference Area.facility_id |
| 44 | iPad evidence photos go to mobile_photo_paths, never result_photos |
result_photos is exclusively for resolution photos added via the web update form. Mixing them causes evidence photos to appear under "Resolution Details" on the web. |
| 45 | PATCH /issues/<id>/photos is idempotent — merge, never overwrite |
Retry-safe: merged = existing + [p for p in new_photos if p not in existing] |
| 46 | Facility deduplication in pullReferenceData() on iOS |
Server may return same facility ID multiple times; deduplicate before upsert using seenFacilityIds = Set<Int>() |
| 47 | Magic-byte validation in _save_photo() |
Added post-phase-19. Reads 8 bytes before saving; rejects files that do not begin with a known image magic (\xff\xd8\xff, \x89PNG, GIF87a, GIF89a). Prevents MIME-type spoofing via extension-only checks. |
| 48 | upload_photo_ajax endpoint on inspections blueprint |
POST /<inspection_id>/upload-photo with @limiter.limit("30 per minute"). Triggers on file selection (not form submit) so photos survive AJAX draft-save and page navigation. Stores in inspection_photos/ subfolder; returns {ok, path}. |
| 49 | Template schema snapshotted at submit time | execute() POST stores form_fields list as _template_schema inside inspection.notes JSON. view() prefers this snapshot over the live template so historical inspection views remain correct if the template changes later. |
| 50 | mobile_local_id UUID format validation on write endpoints |
POST /api/v1/inspections and POST /api/v1/issues validate mobile_local_id against _UUID_RE regex. Rejects non-UUID strings with HTTP 400. Prevents garbage values from being stored as idempotency keys. |
| 51 | Security response headers via @app.after_request |
Added X-Content-Type-Options: nosniff, X-Frame-Options: SAMEORIGIN, Referrer-Policy: strict-origin-when-cross-origin, and a Content-Security-Policy (CDN allowlist + unsafe-inline). Uses setdefault so API responses can override if needed. |
| 52 | Inspection execute.html offline-resilient photo flow |
Photos are uploaded immediately on file selection via uploadPhotoField() (XHR to upload_photo_ajax). Server path is stored in <input type="hidden" id="field_<fid>_server_path">. AJAX draft-save and flag-issue submission read these hidden fields so photos are never lost on navigation. |
| 53 | Flag-issue panel is an offcanvas — not a page navigation | Converted from a navigate-away flow to a Bootstrap offcanvas. Draft is saved first via saveDraft(), then the flag-issue form is submitted via fetch() FormData, then the page reloads. Eliminates the entire class of "photos lost on navigation" bugs. |
| 54 | Bulk issue verification via POST /issues/bulk-verify |
@supervisor_required. Accepts issue_ids list from form. Skips issues not in resolved or pending_verification state. Calls log_action() after db.session.commit() per rule 10. |
| 55 | Scheduled "issues" report groups by facility with SLA status | _build_report_data() now produces issues_by_facility (list of (facility_name, [(issue, sla), ...])) and sla_breached/sla_at_risk counts alongside the flat issues list. CSV builder uses resolved_facility (not area.facility) to avoid crash when area_id is None. |
| 56 | Customer role: POST to issues.view returns 403 |
The view() route checks request.method == 'POST' inside the customer scope block and calls abort(403). Customers have read-only access; the template already hides the update form, but server-side enforcement is required against crafted requests. |
| 57 | Inspector contract scoping: get_inspector_scope() — strict, no fallback |
Inspectors with NO InspectorAssignment rows see nothing (empty list, not None). Returns None only for non-inspector roles. All routes and API endpoints that currently filter by inspector_id or assigned_to/reported_by must instead filter by the facility list returned by get_inspector_scope(). |
| 58 | Inspector scope covers all data in contracted facilities, not just own work | Facility list, inspection list, issue list — all scoped to contracted facilities. Dashboard personal stats (today's work, avg score, trend) additionally filter by inspector_id so the productivity view stays personal. Issues show ALL facility issues, not just assigned ones. |
| 59 | assign_inspector_contracts route replaces the entire assignment set on POST |
The form sends the full checked list; existing assignments not in the POST body are deleted, new ones are inserted. Callers must always POST the complete desired set, not a diff. The page includes Select All / Deselect All buttons (JS-only, no server round-trip) and a live "N assigned" badge that updates on each checkbox change. |
| 60 | flag_issue offcanvas form must include <input type="hidden" name="facility_id"> |
IssueForm.facility_id has DataRequired(). The hand-written offcanvas form in execute.html is not rendered by WTForms, so it must explicitly send facility_id. Without it, form.validate_on_submit() silently returns False, the server responds 200 OK with the flag_issue.html template, and the JS treats res.ok as success — no issue is ever saved. Fix: <input type="hidden" name="facility_id" value="{{ inspection.facility_id }}"> inside #flagIssueForm. |
| 61 | Contract→Facility cascade UI pattern: contract selector is UI-only, not a WTForms field | The "Log New Issue" form (issues/form.html) and both filter bars (issues/list.html, inspections/list.html) use a plain HTML <select id="...contract..."> that triggers an AJAX call to GET /inspections/facilities_for_project/<id> on change, repopulating the facility dropdown. IssueForm.facility_id.choices is always set to ALL active facilities in the route so POST validation passes regardless of which contract was selected in the UI. On POST error re-render, the route derives selected_project_id from the submitted facility_id's project_id and passes it to the template so JS can restore both selectors. |
| 62 | issue.resolved_facility.project and inspection.facility.project give the contract |
Project.facilities declares backref='project', so facility.project is a direct ORM attribute (not a dynamic query). Guard all template accesses: ins.facility.project.name if ins.facility and ins.facility.project else '—'. The contract name is displayed in the issues list, issues detail, and inspections list; the issues list also accepts a contract_id query param that pre-filters the facility dropdown server-side. |
| 63 | Customer Contract filter scoped to assigned contracts only | inspections.index() and issues.index() build the projects list differently for customer role: query CustomerAssignment.query.filter_by(user_id=current_user.id) to get assigned project_id values, then filter Project to that set. All other roles still receive all active projects. Pattern mirrors the existing inspector scoping in inspections.start(). |
| 64 | Invitation/reset email From must be a mail-server-authorized identity; never a bare noreply@<full-host> |
Both _send_invite_email (customers.py) and _send_password_reset_email (auth.py) take an optional base_url (call sites pass request.host_url) and build setup_link/reset_link from effective_base, so the link always points at the host the user is on. The From is where deliverability lives: a per-host noreply@jqc.ltservicesinc.com (subdomain, wrong local part) was accepted by the relay then silently dropped by SPF/DMARC — reset/invite mail never arrived while notification mail (which used MAIL_DEFAULT_SENDER) did. Confirmed July 2026 via SMTP A/B test. Current behaviour: reset password sends from the fixed authenticated MAIL_DEFAULT_SENDER (fallback MAIL_USERNAME); customer invite sends from branded_sender(effective_base) (see §8 mail_utils.py), a (display_name, address) tuple. The display name is always per-domain (BRAND_NAMES), but the From address is branded only for the authenticated domain and any SENDER_AUTHORIZED_DOMAINS — all other domains keep the authenticated address so they always deliver. This is the deliverable default: From: "Gov Services QC" <jqc.noreply@ltservicesinc.com> with zero DNS. To brand the actual address for another domain, set up its SPF include + DKIM, then add it to SENDER_AUTHORIZED_DOMAINS. Never brand an address for a domain lacking SPF/DKIM (accepted-then-dropped, the failure above), and never reintroduce noreply@<full-host>. |
| 65 | Customer "Your Facilities" uses a card grid, not a table | See §18 "Customer Dashboard — Your Facilities Panel". Never revert to a full-width table for this section. The show-more threshold is VISIBLE = 9; the search input threshold is > 6. Both thresholds live as JS/Jinja constants in dashboard.html and can be adjusted together if needed. |
| 66 | FAQ chip text must use data-faq attribute, not onclick with | tojson |
| tojson emits "text" (double-quoted) inside onclick="..." (also double-quoted), breaking HTML parsing and silently truncating the <script> block. Use data-faq="{{ text | e }}" and read via btn.dataset.faq in JS. |
| 67 | display_name in JS must use | tojson, not inline Jinja interpolation |
"Hi {{ name }}" in a JS string literal breaks if name contains " or \. Use var name = {{ name | tojson }}; then concatenate. |
| 68 | Support ticket customer replies revert status from answered → open |
When a customer posts a follow-up on an answered ticket, the route sets ticket.status = 'open' so admins see it in their open queue. Admin must manually close or re-answer. |
| 69 | Customer issue create: assigned_to field hidden, facility_id scoped to get_customer_scope() |
issues.create() detects role == 'customer', scopes facilities to the customer's assigned set, sets staff = [] for the assigned_to dropdown, and hides the field in form.html. IssueForm.facility_id.choices must still include all active facilities so POST validation passes. |
| 70 | notify() does NOT commit — caller must db.session.commit() after all notify() calls |
notify() adds a Notification row to the session but leaves the commit to the caller. The support helpers (_notify_admins_new_ticket, _notify_customer_reply, _notify_admins_customer_reply) each call db.session.commit() after the notify() loop. |
| 71 | ProxyFix must wrap app.wsgi_app in create_app() |
Behind Nginx, remote_addr is 127.0.0.1 for every request without it, collapsing all Flask-Limiter keys into one bucket (global instead of per-client rate limiting). x_for=1 trusts exactly one proxy hop. See §19. |
| 72 | Device registration has exactly ONE implementation — register_device() in app/api/auth.py → api_device_tokens |
A second POST /api/v1/devices/register (app/api/devices.py + DeviceRegistration model) was removed July 2026. It was shadowed by the api_auth route at routing time and queried the dropped device_registrations table. Do not reintroduce a competing device model or duplicate register route. |
| 73 | Per-contract recipients are dispatched ONLY inside notify_by_matrix() — never add a parallel path |
_notify_contract_recipients() runs after role + global-custom-email routing and shares the notified / sent_emails dedup sets. Any new event that should reach contract recipients must go through notify_by_matrix() (passing facility_id, or an issue_id/inspection_id that resolves to one). Bypassing it means contract recipients are silently skipped and dedup breaks. Commit stays the caller's responsibility. |
| 74 | The public blueprint (/f/*) is login-free — keep it occupant-safe |
Pages are addressed by unguessable public_token (never facility id), 404 on inactive/unknown facilities, and expose only a quality rating, last-inspected date, and open-issue COUNT — never issue descriptions, inspector names, per-item scores, or any other facility's data. The report POST must stay CSRF-protected (Flask-WTF form), rate-limited, and honeypot-guarded; public-reported issues are created with reported_by=NULL, severity='medium', and routed through notify_by_matrix('issue_created', facility_id=...). Do not add fields that leak internal detail, and do not reuse render_template('base.html') here — the public page is a standalone template with no authenticated nav. |
| 75 | Email is stored lowercased; look it up case-insensitively | User/customer email is normalized to .strip().lower() at every write site (auth.py profile/create/edit, customers.py invite/edit). Forgot-password lookup uses db.func.lower(User.email) == input so a mixed-case legacy row still matches — a plain filter_by(email=...) silently missed them and sent no reset (the failure was invisible because of the generic "if an account exists…" message). Keep both halves: normalize on write, case-insensitive on lookup. |
| 76 | Transactional email From must be an SMTP-authorized identity, per-domain branding via display name only |
Reset-password sends from MAIL_DEFAULT_SENDER; customer invite sends from branded_sender() = (per-domain display name, authorized address). A per-host noreply@<subdomain> sender is accepted by the relay then dropped by SPF/DMARC. See rule 64 and §8 mail_utils.py. |
21. Change Philosophy
- Surgical, additive patches — smallest possible change to achieve the goal
- Preserve all routes, function names, variable names unless explicitly directed otherwise
- Never remove existing functionality unless explicitly directed
- Log all create/update/delete actions via
log_action() - Migration existence checks — all migrations safe to re-run
- Full file contents for 1–3 file changes; deployment map for larger changesets
- Explicit deploy instructions — migration steps separated from code steps
- Root cause analysis on errors — never apply temporary workarounds
