+             link_type ENUM('duplicate','related') NOT NULL DEFAULT 'related',

+    UniqueConstraint(issue_id, linked_issue_id) — uq_issue_link
+```
+
+**Connects a duplicate to its original, or two issues about the same thing**, so whoever picks one up can reach the other.
+
+**One row is stored per pair and shown on BOTH issues.** The stored direction carries meaning for `duplicate` — `issue_id` is a duplicate *of* `linked_issue_id` — so the same row reads differently at each end: "Duplicate of #B" on one, "Duplicated by #A" on the other. `related` is symmetric and reads "Related to" from either side. `IssueLink.LABELS` is keyed `(link_type, is_source)` and is the only place that wording lives; `label_for(viewing_issue_id)` / `other_issue(viewing_issue_id)` resolve a row against whichever issue is on screen.
+
+Storing one row rather than a mirrored pair keeps the direction unambiguous and makes unlinking a single delete. The cost: **uniqueness cannot be expressed by the UniqueConstraint alone.** `(A,B)` and `(B,A)` are distinct rows to MySQL but the same link to a person, so **`IssueLink.exists_between(a, b)` is the only correct duplicate check** — it looks both ways. The constraint catches the exact-duplicate row; `exists_between()` catches the reverse.
+
+**A link is PURELY NAVIGATIONAL.** Marking a duplicate does **not** touch either issue's status, `resolved_at`, SLA, assignee or followers, and fires no notification. Closing the duplicate stays a separate, deliberate action. Do not add side effects here without saying so in the UI — the link control reads as navigation, and a status write from it would be invisible.
+
+**Two FKs from one table to `issues`, so both relationships pin `foreign_keys`** — the same failure mode as phase56's third `inspections`→`users` FK (§17), which raises on first ORM *use*, not at import. `Issue.links_from` / `Issue.links_to` are the two storage directions; **`Issue.all_links()` merges them** into the single list a person actually sees. Both relationships cascade `all, delete-orphan` (and both FKs are `ON DELETE CASCADE`), so deleting an issue takes its links from *either* end — a surviving link would render a dead row on the other issue's page.
+
+**Nothing here is tenant-aware, deliberately.** The table lives in the tenant DB and routes through `RoutingSession`, so a link can only reach an issue in the same tenant. Scope *within* a tenant is the caller's job — **see rule 110.**

+`phase54` / `phase55` port the ST August-2026 work (ST calls them phase51 /
+phase52; the ids differ because MT's chain was already past those numbers —
+match by NAME, not number, when comparing the two repos).
+
+#### phase54 — per-account notification overrides
+
+Creates `user_notification_matrix` (§5). **No backfill, deliberately** — an
+empty table means every account inherits the global matrix, i.e. exactly
+today's routing, so the migration cannot change who gets notified. Backfilling
+from the current global columns would freeze every account at today's routing
+and silently break later changes to those columns. Table-existence check —
+safe to re-run.
+
+#### phase55 — restrict forms to specific contracts
+
+Creates `template_contracts` (§5 `TemplateContract`). **No rows for a template
+means SHARED**, so every pre-existing form stays available everywhere and the
+migration cannot change behaviour on deploy. Table-existence check — safe to
+re-run.
+
+#### phase56 — assign a follow-up to another inspector
+
+Adds `inspections.follow_up_assigned_to` (FK → `users.id`, ON DELETE SET NULL)
+— see §27c. **No backfill:** NULL means the follow-up belongs to the
+inspection's own inspector, which is what every existing row already means, so
+deploying cannot change who owns anything.
+
+**This is the THIRD FK from `inspections` to `users`** (`inspector_id`,
+`follow_up_requested_by`, and now this). Every relationship spanning the two
+tables must pin `foreign_keys` explicitly or the mapper is ambiguous — and it
+raises on first ORM *use*, not at import, so the app starts cleanly and then
+every request 500s. Column + constraint checks — safe to re-run.
+
+ST calls this phase53; MT's chain was already past that number. Match by NAME.
+
+#### phase57 — link related and duplicate issues
+
+Creates `issue_links` (§5 `IssueLink`). **Purely additive** — nothing reads the
+table until a person creates a link, so an empty table is exactly today's
+behaviour and there is nothing to backfill.
+
+Both issue FKs are `ON DELETE CASCADE`, so a direct SQL delete of an issue
+cannot leave a link pointing at a row that no longer exists (the ORM cascade on
+`links_from`/`links_to` covers the application path). The index names
+deliberately match what SQLAlchemy's `index=True` generates —
+`ix_issue_links_issue_id`, `ix_issue_links_linked_issue_id` — which matters more
+in MT than in ST: a tenant **bootstrapped** from the baseline and one
+**upgraded** through the chain must end up with the same schema, down to the
+index names.
+
+Table-existence check — safe to re-run, as every migration from phase33 on must
+be. `downgrade()` drops the table, discarding every link; no issue is affected,
+since a link never held state belonging to one.
+
+ST calls this phase54; MT's chain was already past that number. Match by NAME.

+`phase41` → `phase52` are the single-tenant feature-parity track — see
+MULTI_TENANT_PLAN.md §12. Two notes on that tail:
+
+* **`phase51_external_inspector`** widens the `users.role` ENUM. It must be
+  deployed together with its code: MT tested `role == 'inspector'` literally in
+  ~80 places, and widening the ENUM alone drops external inspectors into the
+  *unscoped* branch, which is a cross-tenant data leak rather than a cosmetic
+  bug. Use `User.INSPECTOR_ROLES` / `user.is_inspector`, never a literal.
+* **ST's `phase50_default_modern` is deliberately NOT ported.** It overwrites
+  every saved `ui_theme` preference, which in MT would run against every tenant
+  DB. Set `DEFAULT_UI_THEME=modern` per tenant instead. See
+  MULTI_TENANT_PLAN.md §12.3.
+
+Migration revision IDs must be **≤ 32 characters** to fit
+`alembic_version.version_num VARCHAR(32)`.

 ### phase40_support_chat_kb
 
 Creates three tables backing support chat persistence and the AI knowledge base:
@@ -1418,6 +1566,20 @@ set -a; . /etc/jqc/control.env; set +a
 | 95 | **Chat history is loaded from DB — never pass client-sent history to Groq** | phase40. `POST /support/chat/message` loads prior turns from `SupportChatMessage` (newest-first, limit 40, reversed). The JSON body sends only `{ message, session_id }` — no history array. This prevents history tampering by clients and ensures accuracy across page reloads. |
 | 96 | **`db.session.flush()` to get session ID before first message insert** | When creating a new `SupportChatSession` in `chat_message()`, call `db.session.flush()` after `db.session.add(chat_session)` to get the autoincrement `id` before constructing `SupportChatMessage` rows. If Groq fails, `db.session.rollback()` undoes the flush — no orphaned empty session is left in the DB. |
 | 97 | **`send_billing_email()` derives the From address from `APP_BASE_URL` — same pattern as rule 64** | `urlparse(app.config['APP_BASE_URL']).netloc` is extracted before the background thread starts and passed as `sender=f'noreply@{netloc}'` to `Message()`. Falls back to `MAIL_DEFAULT_SENDER` when `APP_BASE_URL` is absent or yields an empty netloc (`sender=None` triggers Flask-Mail's default). Do not hardcode a sender string or duplicate the derivation logic — extend via `send_billing_email()` only. |
+| 99 | **`User.CUSTOMER_ROLES` is for ACCOUNT MANAGEMENT; `role == 'customer'` is for CAPABILITY — never swap them** | Widening a capability check to `CUSTOMER_ROLES` hands a third-party Customer Inspector the customer portal (fails OPEN, nothing errors). Narrowing an account-management check back to `'customer'` strands every Customer Inspector in a page that no longer lists or edits them. `CUSTOMER_ROLES` / `is_customer_account` appear ONLY in: the `/customers` list query and its guards, the `auth.list_users` exclusion, the customer-facing support surface (`_is_customer_side()`), and narrowing uses that WITHHOLD something from an external account (`_assignable_staff_for()`). |
+| 100 | **A per-account notification opt-IN must survive a globally-OFF column** | `notify_by_matrix()` skips a role column early when the matrix says off. For the two customer columns that `continue` must also ask `any(overrides.values())`, or the override saves, displays as on, and never sends. Equally, `notify_customers_for_facility()` re-queries recipients from assignment rows, so `notify_by_matrix()` must hand it `allowed_user_ids` or the facility-scoped path bypasses every override. Both halves are needed. |
+| 101 | **Per-account overrides are enforced in `notify()`, not only `notify_by_matrix()`** | Follower fan-out and direct assignee notifications call `notify()` straight. Gating only the matrix left the editor offering rows ("Issue assigned") that read as Off while the notifications kept arriving. Only an explicit `False` suppresses; the `getattr(recipient, 'is_customer_account', False)` test is deliberate so an unavailable attribute SENDS rather than silently dropping. |
+| 102 | **A template with NO `template_contracts` rows is SHARED, not hidden** | The empty set means "available on every contract" — that is what makes phase55 additive and why it needed no backfill. Reading it the other way hides every pre-existing form from every contract at once. The convention lives in exactly one place, `InspectionTemplate.available_query()`. A facility with no contract gets shared forms only (fail-closed). |
+| 103 | **A bulk-action form must live OUTSIDE the table; row checkboxes join it via the HTML5 `form=` attribute** | Wrapping the table nests the per-row delete/unfollow forms inside the bulk form, and browsers silently discard nested forms (rule 9) — the row buttons post nothing, with no console error and no server log. Applies to all four list templates (classic + modern). |
+| 104 | **Bulk deletes: DB rows first, storage files second** | Collect the keys, `db.session.delete()` every row, `commit()`, and only then `storage.delete()`. `_collect_inspection_photos()` is shared by the single and bulk inspection delete paths so the two cannot drift — a key missed there is an invisible permanent storage leak. |
+| 105 | **The flag-issue assignee list is contract-scoped, and BOTH call sites must use `_assignable_staff_for()`; a failed flag-issue POST must return non-2xx** | `execute()` renders the dropdown, `flag_issue()` builds the choices that validate the POST — the choices are the security boundary. An org-wide list let anyone assign another client's Customer Inspector, who was then emailed the facility name and issue description. And the offcanvas JS branches on `res.ok`, so a 200 re-render of an invalid form reads as success: the panel closes, the page reloads, and no issue exists. |
+| 106 | **Name the Groq model in the chat error log, and keep `_DEFAULT_GROQ_MODEL` current** | Groq retires models without notice; when the configured one disappears the API 404s and EVERY question returns the generic "problem reaching the AI assistant" reply, with nothing else broken — invisible until a customer complains. The fix needs no deploy, only `GROQ_MODEL`, which is exactly what the log line must say. |
+| 107 | **`viewer_is_our_staff` in `issues/view.html` is an explicit role ALLOWLIST, and `external_inspector` is absent on purpose** | `not current_user.is_customer_account` fails OPEN — a missing attribute yields Jinja `Undefined`, `not Undefined` is true, and the internal-process chrome renders for exactly the accounts it must be hidden from. This is not a rule-87 violation: rule 87 governs capability/scoping, where a Customer Inspector must behave like our inspector; this asks "does this person work for us?", the one place the two genuinely differ. |
+| 108 | **A follow-up has exactly ONE owner: use `follow_up_owner` (row) / `follow_up_owned_by()` (query) — never re-derive it** | Assignee when set, original inspector otherwise. The API's two arms must be mutually exclusive (`follow_up_assigned_to == me` OR `assigned_to IS NULL AND inspector_id == me`); drop the `IS NULL` and two people turn up for the same re-inspection. The authorship filter must be DEFERRED when `follow_up_required=true` is requested, or the rows the assignee needs are hidden before the ownership test runs. |
+| 109 | **Inspector READ access is facility scope; WRITE access is authorship** | `index()` lists by facility (rule 58), so `view()`/`export_pdf()` must too — scoping reads by authorship made the list offer rows that said "Access denied" on click, and locked the follow-up assignee out of the parent inspection. `execute`, `save_draft_ajax`, `upload_photo_ajax` and `flag_issue` keep the authorship check: readable is not editable. |
+| 110 | **An issue link is a pointer to another issue — filter it by scope on ALL THREE surfaces** | A link exposes the far issue's id, description, facility and status, so an unfiltered panel lets a customer read an issue at a facility they hold no assignment to, simply because one of our staff linked it. Three surfaces have to hold the line and only one is a real boundary: `_readable_links()` filters what the panel RENDERS, `link_search()` scopes what the picker FINDS, and `add_link()` re-checks on POST — the search is a convenience and must never be trusted as the gate. All three resolve scope through `_viewer_facility_scope()` / `_issue_in_scope()`, the same pair `issues.view()` now uses, so the panel cannot end up more permissive than the page it sits on. `_issue_in_scope` takes a resolved scope rather than a user, so filtering a list costs one assignment query, not one per row. A link to an issue outside your scope reports "not found", never "access denied" — whether another customer's issue exists is not something the link box should confirm. Cross-TENANT isolation is a different layer and is already handled: `RoutingSession` has bound the session to `g.tenant`'s database, so an id from another tenant does not resolve at all. |
+| 111 | **The MT connection ceiling is `workers x [ default pool + cache_cap x tenant pool ]` — never just the default pool** | `config.SQLALCHEMY_ENGINE_OPTIONS` governs only the default bind; in MT nearly every request runs on a per-tenant engine from `app/tenancy/engine_cache.py` with its own `TENANT_ENGINE_*` pool, and each worker caches up to `TENANT_ENGINE_CACHE_MAX` of them. Sizing against the default pool alone is how a box reaches "Too many connections" while the health check reports headroom. `scripts/db_health.py` does the full arithmetic; the cache cap is the multiplier worth lowering first. Both pools set `pool_pre_ping` — without it an idle overnight surfaces as `OperationalError 2006` on the next request. |
+| 112 | **The SLA cron narrows to candidates in SQL; the prefilter is a conservative SUPERSET, never an equality** | `send_sla_alerts()` runs every 30 minutes **per tenant**, so reading the whole open-issue backlog to decide in Python multiplied by the tenant count. The three filters each mirror a `continue` in the loop, and one of them — `reported_at IS NOT NULL` — is a correctness fix, not a speed one: `sla_status()` raises `TypeError` on a NULL and one such row aborted that tenant's entire run. The prefilter deliberately does NOT replicate the "already notified at_risk and still only at_risk" skip (that would mean writing the per-severity deadline arithmetic a second time, in SQL); the loop still applies it, so extra rows are read but no extra notification is sent. Pinned by `tests/test_sla_candidate_query.py` — a change that makes the prefilter narrower than the loop is a silently unsent alert. |
 | 98 | **Reports R1 + R2 contract cascade is client-side only — facility_id is the sole DB filter** | The Contract dropdown in `reports/issues_aging.html` and `reports/sla_compliance.html` has no `name` attribute and is never submitted. It exists only to narrow the Facility `<select>` in the browser via `GET /inspections/facilities_for_project/<id>`. The routes receive and filter on `facility_id`; `contract_id` plays no role server-side. Do not add server-side `contract_id` filtering to these routes — it would duplicate what `facility_id` already provides. |

-## 26. Coding Rules for AI Assistants
+## 26. Web Portal Design (MT-16)
+
+Two designs share one set of page templates.
+
+* `base.html` is a **one-line dispatcher**: `{% extends jqc_layout %}`. Page
+  templates keep `{% extends "base.html" %}` and need no edits.
+* `layouts/classic.html` is the original chrome, verbatim.
+  `layouts/modern.html` is the sidebar shell.
+* `jqc_layout` comes from `inject_ui_theme()` in `app/__init__.py`, driven by
+  `users.ui_theme` with config `DEFAULT_UI_THEME` as the fallback.
+* Per-page overrides live at `templates/modern/<same path>.html` and are indexed
+  once at boot. Look for `UI themes | modern overrides indexed: N` in the log —
+  `0` on a host that should have them means the directory did not deploy.
+
+**Do not move the template swap into the Jinja loader.** It lives in
+`ThemedEnvironment.get_template()` so the template cache is keyed on the
+*rewritten* name. A loader-level swap caches under the original name, so a
+modern template can be served to a classic user — and in MT, where one worker
+serves many tenants, across tenants.
+
+When adding a page: write it once as a normal template. Only add a
+`modern/` override if the layout genuinely differs; styling alone is handled by
+`static/css/theme_modern.css`, which is scoped to `body.jqc-modern`.
+
+---
+
+## 27. Roles (MT-15)
+
+`users.role` ENUM: `admin`, `director`, `inspector`, `external_inspector`,
+`project_manager`, `customer`, `auditor`.
+
+**Never test `role == 'inspector'`.** `external_inspector` (customer /
+third-party inspectors) has identical capabilities and identical
+`InspectorAssignment` scoping. Use:
+
+* `user.is_inspector` — true for both inspector roles; use for every capability
+  and scoping check
+* `User.INSPECTOR_ROLES` — for `User.role.in_(...)` queries
+* `user.is_external_inspector` — only where the two genuinely differ (display)
+* `user.role_label` / `ROLE_LABELS` — for any role name shown in the UI
+
+A literal comparison sends external inspectors down the unscoped branch, where
+`get_inspector_scope()` returns `None` and every downstream query drops its
+facility filter. That is a cross-customer leak.
+
+External inspectors are **invited**, never given a password: `password_set=False`
+plus an emailed 72-hour token, with `auth.resend_invite` for bounced invitations.
+
+---
+
+## 27b. Customer-side roles, per-account notifications, per-contract forms (Aug 2026 ST parity)
+
+Ported from the single-tenant app (its phase51 + phase52 + the August fixes).
+Nothing here is tenant-aware in its own right — every table lives in the tenant
+DB and every query routes through `RoutingSession` as usual.
+
+### The two customer-side roles
+
+| Stored ENUM value | Display label | Scoped by | Capabilities |
+|---|---|---|---|
+| `customer` | **Customer Director** | `CustomerAssignment` | The portal, unchanged — plus planning scheduled inspections at their own facilities |
+| `external_inspector` | **Customer Inspector** | `InspectorAssignment` | Identical to the internal `inspector`, plus the customer support surface (AI chat + tickets) |
+
+**LABEL-only rename** — the ENUM values are untouched, so no migration and no
+role check moved. `User.ROLE_LABELS` is the one place the names live.
+
+`User.CUSTOMER_ROLES = ('customer', 'external_inspector')` and
+`User.is_customer_account` answer an **account-management** question ("is this
+managed under `/customers`?"). Every **capability** check — portal gates,
+`@customer_required`, `get_customer_scope()`, `notify_customers_for_facility()`,
+the customer branch of each `app/api/*` module — keeps testing
+`role == 'customer'` exactly (rule 99).
+
+Both roles are now created, invited, assigned and switched in **Customer
+Management** (`/customers`); `auth.list_users` excludes them and the
+`/auth/users/...` URLs redirect to `customers.manage`. `UserForm` no longer
+offers `external_inspector`, and `auth.create_user` always requires a password
+— customer-side accounts are invited (they choose their own username and
+password) via `customers.create()`. `POST /customers/<id>/switch-role`
+(admin only) mirrors contracts across the two scoping tables and revokes the
+account's refresh tokens + device rows, because API access differs between them.
+
+### `UserNotificationMatrix` (per-account overrides)
+
+Row `enabled=True` = send even if the global column is OFF; `enabled=False` =
+never send even if it is ON; **no row = inherit**. Inherit is the default, so
+the table shipped empty and changed routing for nobody, and setting a row back
+to inherit DELETES it. Helpers live in
+`app/models/user_notification_matrix.py`; edited on the account's Customer
+Management page as a tri-state. Enforced in **`notify()` as well as**
+`notify_by_matrix()` — follower fan-out and direct assignee notifications reach
+`notify()` straight, so gating only the matrix left rows that read as Off while
+notifications kept arriving. See rules 100 and 101.
+
+### `TemplateContract` (forms per contract)
+
+`InspectionTemplate.available_query(project_id)` is the single definition of
+"which forms may this contract use" — pickers, the POST validation behind them,
+the schedule form and `GET /api/v1/templates` all call it. **No rows = shared**
+(rule 102). Managed in three places: the template list's Edit modal
+(`POST /templates/<id>/rename`, carrying a hidden `contracts_present=1`
+marker), Create Template, and the full form editor. `duplicate_template()`
+copies the restrictions.
+
+### Other ported behaviour
+
+* **Bulk actions** on the issues and inspections lists (`POST /issues/bulk`,
+  `POST /inspections/bulk`) with shared partials in `templates/partials/`.
+  Toolbar form sits OUTSIDE the table; row checkboxes join it with the HTML5
+  `form=` attribute (rule 103). Deletes remove DB rows first, storage keys
+  second (rule 104).
+* **List filter preservation** — `current_url()` (Jinja global) +
+  `return_url(fallback)` (`utils/decorators`) round-trip the full list URL as
+  `next`, so an edit or delete returns to the filtered page.
+  `safe_redirect_url` still guards every hop.
+* **Flag-issue assignee scoping** — `_assignable_staff_for(inspection, actor)`
+  in `routes/inspections.py` is the single source for both the offcanvas
+  dropdown and `form.assigned_to.choices` (the actual POST validation). A
+  failed flag-issue POST now returns **400**, because the offcanvas JS branches
+  on `res.ok` (rule 105).
+* **Customer Directors plan inspections** — `schedule_manager_required` in
+  `routes/inspection_schedules.py` = the manager set plus `role == 'customer'`.
+  Because that blueprint builds its form by hand (no WTForms SelectField),
+  narrowing the choice lists is NOT the validation: `_scope_errors()`
+  re-checks facility, inspector and form-vs-contract on every POST, and
+  `_schedule_in_scope()` guards edit/delete. Start remains the assignee's.
+* **Support chat serves both customer roles** — `_is_customer_side()` opens the
+  door, then `_support_facilities()` branches per role (CustomerAssignment vs
+  InspectorAssignment) and `_system_prompt_for()` appends
+  `_INSPECTOR_ADDENDUM` for a Customer Inspector. The curated knowledge base is
+  now spliced in **before** the `Rules:` heading (`_STYLE_MARKER`) — appended
+  after it, the prompt's own "ground answers in everything above" put it out of
+  scope, which is why KB entries looked ignored. `/support/admin/knowledge/preview`
+  shows the exact prompt. `GROQ_MODEL` defaults to `_DEFAULT_GROQ_MODEL`
+  (`openai/gpt-oss-120b`); Groq retires models without notice, and the error
+  handler names the model and says to set `GROQ_MODEL` (rule 106).
+* **`COMMENTS_VISIBLE_TO_ALL`** (config, default true) lifts the phase22 read
+  filter so customers see every comment. `is_customer_visible` is still
+  written, so flipping it back restores the old behaviour with nothing to
+  repair. `issues/view.html` gates the internal chrome on
+  `viewer_is_our_staff` — an explicit allowlist of OUR roles, which fails
+  closed and deliberately excludes `external_inspector` (rule 107).
+
+---
+
+## 27c. Follow-up assignment + inspector read access (Aug 2026 ST parity)
+
+Ported from ST (its phase53 + the two fixes shipped beside it).
+
+### Assigning a follow-up (phase56)
+
+A follow-up used to belong implicitly to whoever performed the original
+inspection. `inspections.follow_up_assigned_to` lets a director — or a
+**Customer Director**, for their own facilities — hand the re-inspection to
+someone else. `Inspection.follow_up_owner` (assignee *or* inspector) is the
+single definition of ownership, so the web display, the notification and the
+mobile API filter cannot disagree.
+
+**The assignee takes over**: only the owner is notified, and only the owner
+sees it. In `GET /api/v1/inspections?follow_up_required=true` the two arms are
+mutually exclusive — without `is_(None)` on the second arm the original
+inspector keeps seeing a follow-up handed to someone else and two people turn
+up to do it. The generic "inspectors see only their own inspections" filter is
+**deferred** when follow-ups are requested, because an assigned follow-up lives
+on an inspection somebody else performed.
+
+The picker (`_followup_assignees_for()`) is contract-scoped for the same reason
+the flag-issue list is (rule 105), offers only the two INSPECTOR roles, and the
+POST re-validates against it. A facility with no contract offers nobody —
+fail-closed, the follow-up stays with the original inspector.
+
+**MT-only gap closed on the way:** MT's `GET /api/v1/inspections` had no
+`follow_up_required` filter at all, so the iPad's Follow-up Requests screen
+received the inspector's entire history. The filter now matches the web's
+definition of "follow-up" — flagged, completed, and not yet answered by a
+linked re-inspection (`~follow_ups.any()`).
+
+### Inspector READ access follows the list, not authorship
+
+`index()` scopes an inspector by FACILITY (rule 58), but `view()` and
+`export_pdf()` scoped by authorship — so the list offered rows that answered
+"Access denied" on click, and the follow-up assignee could not open the parent
+inspection they had just been asked to re-inspect. Both reads now use
+`_inspector_may_read()` (facility scope). **Writes stay owner-only**: `execute`,
+`save_draft_ajax`, `upload_photo_ajax` and `flag_issue` keep the authorship
+check. `reinspect()` belongs to the follow-up's owner; the buttons render only
+for `is_own_inspection or owns_follow_up`, so the page never shows a control
+that fails on click.
+
+### One rule, two expressions, three callers
+
+Ownership has to be stated twice — once for a loaded row, once in SQL — so both
+live together in `models/inspection.py`:
+
+* `follow_up_owner` — the property (assignee, else inspector)
+* `follow_up_owned_by(user_id)` — the query predicate
+
+Every query that scopes follow-ups calls the predicate: the mobile list filter,
+the web dashboard card, and the iPad stats KPI. They each used to write their
+own version and three tested AUTHORSHIP, so an assignee saw the work in their
+list while both dashboards read 0 — the stats KPI sitting directly above the
+Follow-up Requests list it disagreed with. Fixed in ST at the same time.
+Pinned by `tests/test_followup_ownership.py`.

+
+## 29. Photo Object Storage (R2)
+
+**Goal:** photo **files** live in Cloudflare R2 (S3-compatible, $0 egress), not on
+the server's local disk. The DB is not the bottleneck — rows are tiny, PDFs are
+streamed via `BytesIO` and never written to disk. Only photos accumulate, and in
+a multi-tenant deployment they accumulate from every tenant onto one volume.
+
+**No schema change, ever.** The DB stores an unprefixed relative path
+(`uploads/issue_photos/abc.jpg`) and continues to. That string is the storage
+**key**; `app/utils/storage.py` maps it to a backend.
+
+### Key mapping (the rule that matters)
+
+| Layer | Value |
+|---|---|
+| DB (`issues.photo_path`, `result_photos[]`, `mobile_photo_paths[]`, `inspections.form_data`, `inspection_results.photo_path`) | `uploads/issue_photos/abc.jpg` |
+| Local backend, on disk | `app/static/uploads/issue_photos/abc.jpg` |
+| S3 backend, object key | `t<tenant_id>/uploads/issue_photos/abc.jpg` |
+
+The `t<tenant_id>/` prefix is applied **only** inside `S3Backend._object_key()`,
+from `g.tenant`. It never enters the DB, a template, or an API payload — so the
+tenant DB stays portable and every caller stays tenant-agnostic. The **local**
+backend deliberately does not prefix: prefixing would relocate every existing
+file, and the local layout must remain byte-identical to what predates the seam.
+Local mode therefore shares one uploads directory across tenants — an isolation
+weakness inherited from before multi-tenancy, and the reason to move to `s3`.
+
+`S3Backend.save()` **raises** when `MULTI_TENANT_ENABLED` is true and no tenant
+is bound, rather than writing an unprefixed key that a second tenant could later
+collide with. Reads are more forgiving: `read()` / `exists()` / `delete()` try
+the prefixed key and then the bare key, so objects written before the prefix
+existed stay reachable. Pinned by `tests/test_storage_backend.py`.
+
+### Config (all env, per deployment)
+
+`STORAGE_BACKEND=local|s3` (default `local`), plus `R2_ENDPOINT_URL`,
+`R2_ACCESS_KEY_ID`, `R2_SECRET_ACCESS_KEY`, `R2_BUCKET`, `R2_PRESIGN_TTL`
+(default 86400), `R2_MEDIA_FALLBACK` (default false). `boto3` is imported lazily,
+so `local` deployments never touch it — but it **is** in `requirements.txt`,
+because `STORAGE_BACKEND=s3` fails at first upload without it.
+
+`STORAGE_BACKEND` is process-wide, not per-tenant: one bucket, one backend, all
+tenants, isolated by prefix. A per-tenant backend would need the resolver to
+carry a storage selector and `get_backend()` to cache per tenant instead of per
+app — do not half-build it.
+
+**CSP:** `set_security_headers` in `app/__init__.py` derives the R2 host from
+`R2_ENDPOINT_URL` and appends it to `img-src` automatically. Presigned images are
+blocked by the browser without this. A custom R2 domain must be added too.
+
+### Operator scripts
+
+- `scripts/audit_photos.py` — read-only. Per tenant, collects every key its DB
+  references and reconciles against disk. Records the baseline that must still
+  resolve after cutover, and flags any key claimed by more than one tenant.
+- `scripts/migrate_photos_to_r2.py` — copy-only, idempotent, resumable,
+  MD5+size verified. Uploads each tenant's referenced files to `t<id>/…`.
+  Exit 0 only when everything verifies. Orphans (referenced by no tenant) are
+  **not** uploaded — no prefix could legitimately claim them.
+
+Both establish file ownership from tenant DB references, because the shared
+local directory carries none. Both need `CONTROL_DATABASE_URL` +
+`CONTROL_FERNET_KEY`; neither writes to any database.
+
+**Rollback is one env var:** `STORAGE_BACKEND=local` + restart. The sync never
+deletes local files, so the old tree is intact indefinitely.
+
+---
+
+## 30. Database Health Check (`scripts/db_health.py`)
+
+A standalone operations tool for the MySQL side. It imports the app factory for
+config and nothing else — no request layer, no uploads tree — and the plain
+invocation is **strictly read-only** (INFORMATION_SCHEMA / SHOW / EXPLAIN only).
+
+```bash
+set -a; . /etc/jqc/control.env; set +a        # needed for any --tenant but 'default'
+
+python scripts/db_health.py                            # default bind, read-only
+python scripts/db_health.py --tenant all               # every tenant schema
+python scripts/db_health.py --tenant acme --json /tmp/db.json
+python scripts/db_health.py --tenant all --analyze     # refresh optimizer stats (safe)
+python scripts/db_health.py --tenant acme --optimize --yes   # rebuild (LOCKS)
+python scripts/db_health.py --tenant all \
+    --emit-migration migrations/versions/phase58_perf_indexes.py \
+    --revision phase58_perf_indexes
+```
+
+**Every tenant has its own database built from the same chain, so a schema check
+is per tenant, not per deployment.** `--tenant` takes `default` (the
+`SQLALCHEMY_DATABASE_URI` bind — the whole story in single-tenant mode, and the
+fallback bind in MT), a slug, or `all`. Tenant modes resolve through the control
+plane exactly as `control/backup.py` does, and open each tenant with a
+`NullPool` engine: a one-shot CLI must not open a full pool per tenant against
+the very `max_connections` it is checking.
+
+The **server-level** checks (`max_connections`, `wait_timeout`,
+`innodb_buffer_pool_size`, slow-query log, STRICT mode) describe the MySQL
+instance, not a schema, so they run **once** against the first database opened.
+Everything schema-shaped — hygiene, footprint, missing/redundant indexes,
+unindexed FKs, EXPLAIN — runs per tenant, and each finding is tagged with the
+tenant it came from.
+
+**It never DROPs anything.** Redundant indexes are reported with the SQL to run
+by hand, because "unused" is a judgement the tool should not make for you. It
+also refuses to offer an **FK-backed** index as a drop candidate — dropping one
+fails with errno 150.
+
+**Prefer `--emit-migration` over `--apply-indexes` in MT.** An index applied by
+hand to one tenant leaves every other tenant's schema different from it; a
+migration reaches all of them through the normal
+`python -m control.tenant_migrate upgrade --tenant all`. `--emit-migration`
+writes ONE re-runnable migration for the union of what every inspected tenant is
+missing (the chain is shared — emitting one per tenant would produce conflicting
+revisions), with INFORMATION_SCHEMA guards per rule 16. It guesses
+`down_revision` from the versions directory — confirm against
+`python -m control.tenant_migrate heads` before committing.
+
+`RECOMMENDED_INDEXES` in the script is the **single place** the index wish-list
+lives, and every entry names the query that justifies it. An index nothing runs
+is pure write-amplification, so keep speculative entries out — and when a new
+hot query lands, add its index there rather than to an ad-hoc migration, so the
+checker keeps agreeing with the schema.
+
+The connection-ceiling check is MT-aware — see **rule 111**.

+- there was no cutover tooling, and ST's could not be reused (below).
+
+**Why ST's sync script does not port.** The local backend deliberately does not

+from each tenant DB's references, then written under `t<tenant_id>/`.

+## 12. Feature parity with the single-tenant tree (MT-10 → MT-17)
+
+MT forked from the single-tenant codebase (`LT_Janitorial_Quality_Control`, "ST")
+before ST continued shipping features. This section records how that gap was
+closed. It is **complete** as of MT-17.
+
+### 12.1 Why the two trees look more different than they are
+
+A file-by-file comparison of the two trees overstates the gap. Several ST files
+have no MT counterpart *by name* while the feature is fully present under MT's
+own naming. These are **not** gaps and must not be "fixed":
+
+| ST | MT equivalent |
+|---|---|
+| `models/scheduled_inspection.py` | `models/inspection_schedule.py` |
+| `routes/scheduled_inspections.py` | `routes/inspection_schedules.py` |
+| `routes/public.py` | `routes/facility_qr.py` |
+| `models/notification_recipient.py` | `models/project_recipient.py` |
+| `ContractNotificationRecipient` / `get_event_types()` | `ProjectNotificationRecipient` / `get_events()` |
+| `app/add_form_schema.py` | `scripts/add_form_schema.py` |
+| `support/admin_conversation_detail.html` | `support/conversation_detail.html` |
+
+There is also one place where **MT is ahead of ST**: `utils/forms.py`
+`strong_password()` (length + complexity + common-password blocklist) versus
+ST's bare `Length(min=6)`. Porting ST's version would be a downgrade.
+
+### 12.2 Phase log
+
+Migrations `phase41` → `phase56` in `migrations/versions/` are the parity track:
+auditor role, area QR tokens, schedule plan fields, internal handler, frequency
+ENUM widening, recurrence, end date, parent inspection, follow-up attribution,
+schedule acknowledgement, and then:
+
+**Aug 2026 tail — ST parity, ported after MT-17.** ST's chain numbers these
+differently (its phase51/52/53); MT's was already past those numbers, so match
+by NAME:
+
+| MT | ST | What |
+|---|---|---|
+| `phase54_user_notif_matrix` | phase51 | Per-account notification overrides for the two customer-side roles. Empty table = everyone inherits the global matrix, so it shipped changing nothing. See CLAUDE.md §27b. |
+| `phase55_template_contracts` | phase52 | Forms restricted to specific contracts. **No rows = shared**, which is why it needed no backfill. |
+| `phase56_followup_assignee` | phase53 | `inspections.follow_up_assigned_to` — hand a re-inspection to another inspector. NULL = the inspection's own inspector, as before. See CLAUDE.md §27c. |
+
+Shipped alongside them, without migrations: customer-role management under
+`/customers`, bulk actions on the issues/inspections lists, list-filter
+preservation, contract-scoped flag-issue assignees, Customer Directors planning
+their own inspections, and the support surface serving both customer roles.
+
+**MT-15 — External Inspector role. ✅ DONE** (`phase51_external_inspector`)
+Adds `external_inspector` to the `users.role` ENUM: an inspector employed by the
+customer or a third party, with identical capabilities to `inspector` and scoped
+the same way through `InspectorAssignment`.
+
+The ENUM widening and the code **must ship together**. MT had ~80 sites testing
+`role == 'inspector'` with a literal comparison; widening the ENUM alone would
+make every one of them evaluate False for the new role and fall through to the
+*unscoped* branch — `get_inspector_scope()` returns `None`, downstream queries
+drop their facility filter, and an inspector employed by one customer sees every
+other customer's contracts. `User.INSPECTOR_ROLES` (exposed as the
+`is_inspector` property) is now the single definition, and
+`test_external_inspector_scope_is_not_unrestricted` fails loudly if anyone
+reverts a membership test to a literal.
+
+Also in this phase: external inspectors are **invited**, never given a password
+(`password_set=False` + emailed 72-hour token, reusing the customer invite mail),
+with a new `auth.resend_invite` route so a bounced invitation cannot brick an
+account permanently. Creating any other role with a blank password is now
+rejected — it previously stored the hash of the empty string.
+
+**MT-16 — Modern web portal design. ✅ DONE** (`phase52_user_ui_theme`)
+Ports ST's `phase48`. `base.html` became a one-line dispatcher
+(`{% extends jqc_layout %}`); the old chrome moved verbatim to
+`layouts/classic.html`; `layouts/modern.html` is the sidebar shell. All existing
+page templates needed **zero edits** — Jinja resolves `{% block %}` overrides
+through the whole inheritance chain.
+
+`ThemedEnvironment.get_template()` swaps `x.html` → `modern/x.html` for modern
+users. **The swap is in `get_template()`, not the loader, on purpose:** Jinja's
+template cache is keyed on the name `get_template()` receives, so a cached
+modern template can never be served to a classic user — and in MT, where one
+Gunicorn worker serves many tenants, a loader-level swap would leak across
+tenants too.
+
+MT-specific adaptations that ST's files required: tenant branding (ST hardcodes
+its own company name), `inspection_schedules` for ST's `scheduled_inspections`,
+`facilities.qr_print_all` for ST's `facility_qr_print_all`, the billing banner,
+`role_label` for MT-15's new role, and a rewritten tenant-neutral About page.
+`_quota_warning.html` is deliberately **not** in the modern layout — it is a
+per-form include, not chrome, and would render twice on four pages.
+
+**MT-17 — Enrollment intake form. ✅ DONE** (no migration)
+Ports ST's `app/enrollment/` — a public, login-free intake form plus an
+admin-only inbox, kept deliberately outside the schema (flat JSON, no model, no
+migration, deletable package).
+
+**Tenant isolation was the change ST's version required.** ST keeps every
+submission in one flat directory; in MT that directory is shared by every tenant
+on the host, so `/enrollment/admin` would list other organisations' submissions.
+Submissions are now filed under `<ENROLLMENT_DIR>/t<tenant_id>/`, mirroring
+`storage.tenant_key_prefix()`. When multi-tenancy is on and no tenant is bound,
+`storage.enrollment_dir()` **raises `TenantUnresolved` rather than falling back
+to the root** — a fallback would be a silent cross-tenant leak; an exception is
+loud and safe.
+
+Branding was the second change: ST hardcodes its company name in four places and
+a personal Gmail address as the customer-facing "corrections" contact. Both now
+resolve from `TenantSettings`, with a test that greps the package so they cannot
+silently return.
+
+### 12.3 Deliberate divergence: ST `phase50_default_modern` is NOT ported
+
+ST's `phase50` flips the `ui_theme` column default to `modern` **and** runs:
+
+```sql
+UPDATE users SET ui_theme = 'modern' WHERE ui_theme = 'classic';
+```
+
+That overwrites every saved preference. It was defensible for a single-tenant
+deployment deciding for its own staff after its own A/B test.
+
+**It is not portable to MT.** The same statement runs against *every tenant
+database*, flipping the entire UI for tenants who never saw the test and never
+asked. MT therefore ships the `phase48` semantics only: default `classic`, **no
+backfill of any kind**.
+
+The effective default for accounts that never chose is config
+`DEFAULT_UI_THEME` (`app/__init__.py::resolve_ui_theme`), which reads the
+environment and itself defaults to `classic`. A stored `users.ui_theme` always
+wins. **To put a tenant on the modern design, set `DEFAULT_UI_THEME=modern` in
+that tenant's process environment** — a config change, reversible, with no
+preferences destroyed. `test_new_user_defaults_to_classic` pins this so a future
+port of `phase50` has to be a deliberate act.
+
+### 12.4 Open decisions
+
+- **Seat quota.** `tenancy/quota.py::count_active_users()` counts all active
+  users regardless of role, so external inspectors consume a seat against
+  `max_users`. Intentional (they are real accounts), but tenants near their cap
+  will hit `@quota_soft_check('users')` when inviting third parties. Excluding
+  them is a billing-policy decision, not a bug fix.
+- **`enrollment/schema.py::CORRECTIONS_EMAIL`** is now an empty last-resort
+  default. Decide whether to drop the constant and its two config fallbacks in
+  favour of requiring `TenantSettings.support_email`.
+
+### 12.5 Deferred, with reasons
+
+- **`_handler_split` dashboard cards.** ST's classic dashboard shows handler
+  breakdowns for *opened today* and *unassigned* as well as open issues. MT
+  supplies `handler_breakdown` (open issues) and both MT dashboards render it;
+  the other two would require converting `.count()` queries to `.all()` and
+  fetching full rows for a cosmetic card, which regresses large tenants. If
+  wanted, do it as a SQL `GROUP BY handler_type` rather than ST's Python-side
+  count over fetched rows.
+- **PDF / audit hardening.**
+- **MT-9 iOS client** (see §7).

+Per-account notification overrides (phase51).
+
+The global NotificationMatrix routes an event to whole ROLES: "every Customer
+Director hears about issue_created". That is the wrong grain for customers —
+each customer organisation states on its enrollment form which notifications
+each of its people wants, and two directors on two contracts rarely want the
+same set.
+
+This table is the per-account layer on top. One row = one account's explicit
+answer for one event:

+    enabled=True   send it to this account even if the global column is OFF
+    enabled=False  do not send it to this account even if the global column is ON
+    NO ROW         inherit — whatever the global matrix column says
+
+Inheritance is the default and the safe state: an account with no rows behaves
+exactly as it did before this table existed, so the feature ships without
+changing routing for anyone. Setting a row back to "inherit" DELETES it rather
+than storing a copy of the current global value, so a later change to the
+global matrix still reaches accounts that never expressed an opinion.
+
+Scope: consulted for the two customer-side roles only (User.CUSTOMER_ROLES).

+    The candidate list is scoped by the inspection's CONTRACT, not taken

+
+    1. **Cross-customer leak.** A Customer Inspector could assign an issue to
+       anyone in the system — including another client's Customer Inspector.
+       The assignee is notified by email and in-app with the facility name and
+       issue description, so this handed one customer's data to another. It is
+       a leak whoever flags the issue, so the contract scope is applied to the
+       two inspector roles for EVERY actor, not just customer ones.
+
+    2. An external account should not see our internal org chart at all. For a
+       customer-side actor the list is their co-workers on shared contracts —
+       inspectors assigned to this inspection's contract — and nothing else.
+
+    Rules applied:
+      * inspector / external_inspector  -> only those holding an
+        InspectorAssignment on this inspection's contract (the same rows
+        get_inspector_scope() reads, so the list can never disagree with what
+        the assignee can actually open).
+      * director / project_manager / auditor -> org-wide, but offered ONLY to
+        our own staff. These roles carry no InspectorAssignment rows, so
+        contract-scoping them would remove them entirely and break the normal
+        "escalate to the contract manager" flow.
+      * inactive accounts are never offered.
+
+    A facility with no contract yields no contract-scoped candidates; that is
+    fail-closed and correct — an external actor then gets an empty list and can
+    only leave the issue unassigned.
+
+    Used by BOTH the offcanvas dropdown in execute() and the choices that
+    validate the POST in flag_issue(). They MUST stay identical: a value the UI
+    offers but the choices reject fails `validate_on_submit()`, and the
+    offcanvas JS treats the resulting 200 as success — the issue is silently

+     .bulk-check-all   the header select-all box

+     [data-bulk-confirm] optional confirm text, count substituted for {n}

 Each tenant has its own database, hence its own engine + connection pool.
 Engines are created lazily on first use and reused across requests. Total

-a real scaling lever (see MULTI_TENANT_PLAN.md §4); tune via config, or set a
-small pool / switch to NullPool when the tenant count grows large.
+backend connections ≈ workers × cached-tenants × (pool_size + max_overflow),
+so the cache is BOUNDED (MT-21): it holds at most
+``TENANT_ENGINE_CACHE_MAX`` engines and evicts the least-recently-used one
+beyond that, disposing it. Without the bound, a process that has served N
+tenants holds N pools forever, and the connection count grows without limit
+until MySQL's ``max_connections`` (default 151) rejects new sessions.
+
+Worked example — 8 workers, pool_size 2 + max_overflow 3, cache cap 32:
+    8 × 32 × 5 = 1280 worst case, vs. unbounded before this change.
+
+Eviction disposes the engine, which closes its *idle* pooled connections.
+Connections already checked out by another thread stay valid and are closed
+when returned, so eviction is safe under concurrency; the evicted tenant
+simply rebuilds its engine on the next request.
 
 `invalidate(tenant_id)` drops a cached engine (e.g. after credential rotation
 or tenant suspension); the next request rebuilds it.

+------------------------------
+MT-21: bind a browser session to the tenant that issued it.
+
+Why this exists
+---------------
+Every tenant is served by the same Flask application with the same
+``SECRET_KEY``. Before this module, nothing in a signed cookie identified
+*which* tenant it was issued by, so a cookie minted on one tenant host
+validated perfectly on another:
+
+    1. A legitimate user of tenant A logs in at a.jqc.app.
+    2. They copy their session cookie onto b.jqc.app (devtools / curl —
+       host-only cookie scoping stops the *browser* replaying it, but not a
+       person doing it by hand).
+    3. The tenancy middleware resolves Host → tenant B and binds tenant B's
+       database.
+    4. Flask-Login calls load_user('7') and gets **tenant B's user #7**.
+
+The signature was always valid, because it is the same key. The identity was
+never checked against the tenant. Result: authentication as an arbitrary user
+in any tenant whose hostname the attacker knows.
+
+Two layers close this, and both live here:
+
+``SESSION_TENANT_KEY``
+    A ``_tenant_id`` marker written into the session at every point where the
+    session starts carrying identity (login, MFA challenge hand-off,
+    impersonation). ``enforce_session_tenant()`` clears the whole session when
+    that marker disagrees with the resolved tenant, so pre-authentication
+    session state (``mfa_pending_user_id`` and friends) cannot cross tenants
+    either.
+
+``tag_user_id`` / ``parse_user_id``
+    Flask-Login derives BOTH the session ``_user_id`` and the "remember me"
+    cookie payload from ``User.get_id()``, and feeds both back through
+    ``user_loader``. Tagging the id there — ``"<tenant_id>:<user_id>"`` — is
+    therefore a single seam that covers both cookies. Clearing the session
+    alone would not have been enough: a remember-me cookie repopulates the
+    session immediately afterwards.
+
+Single-tenant behaviour is unchanged. When ``MULTI_TENANT_ENABLED`` is False,
+or no tenant is bound (cron, CLI, exempt paths), ids stay bare integers and
+the enforcement is a no-op.

+"""
+app/utils/photo_stamp.py
+------------------------
+Burn a capture-time + geolocation overlay into uploaded evidence photos.
+
+Applied at UPLOAD time (``app/api/photos.py``) rather than on
+``PATCH /issues/<id>/photos``. At upload the raw bytes and any camera EXIF are
+in hand, so nothing has to be read back out of R2, and each upload writes
+exactly one already-stamped object. That also keeps stamping clear of the
+retry/double-burn hazard the PATCH endpoint would have — it is deliberately
+idempotent and re-runnable (CLAUDE.md rule 45), so burning there could stack a
+second bar onto an already-stamped image.
+
+Metadata resolution order
+-------------------------
+1. Client-supplied ``captured_at`` / ``latitude`` / ``longitude`` — most
+   reliable for an offline-first app: the iPad knows when and where the shot
+   was taken even if it syncs hours later.
+2. The image's own EXIF ``DateTimeOriginal`` / ``GPSInfo``.
+3. Server receipt time (last resort; no geo).
+
+FAILURE POLICY
+--------------
+Stamping must never cost us the photo. Every failure path falls back to
+storing the original bytes unmodified — an unstamped photo beats a lost one.
+
+MULTI-TENANT NOTES (MT-12)
+--------------------------
+Ported from the single-tenant tree. This module is tenant-agnostic by
+construction and needs no tenancy awareness:
+
+  - It only transforms bytes. It never touches the DB, ``g.tenant``, or a
+    storage key, so there is nothing here that could leak across tenants.
+  - ``stamp_file_storage()`` returns a FileStorage carrying the ORIGINAL
+    ``filename`` and ``content_type``, so ``storage.save()`` derives exactly the
+    same ``uploads/<subfolder>/<uuid>.<ext>`` key it would have derived for the
+    unstamped upload. The per-tenant ``t<id>/`` prefix is applied further down,
+    inside ``S3Backend._object_key`` — stamping happens strictly upstream of
+    that and cannot interfere with it.
+  - Because the bytes are stamped BEFORE ``storage.save()``, exactly one
+    already-stamped object is written per upload and nothing is ever read back
+    out of R2 to be re-encoded.
+
+Scope matches the single-tenant tree deliberately: only the mobile API upload
+path (``app/api/photos.py``) stamps. Web uploads through
+``routes/inspections._save_photo`` are NOT stamped, there or here — a desk user
+attaching a file has no capture-time or GPS to burn in, and the server receipt
+time would be misleading.
