Overview
Start the LAN App: How to start FPH LAN EMS, sign in, import an event, and give operators the correct local URLs. This page is written for event leads, LAN operators, check-in staff, POS staff, roster leads, local admins, and support reviewers, so it uses operational language: what the area is for, what can change, what can go wrong, and what proof another reviewer should expect.
EMS LAN work should be treated as an accountable handoff, not as a private technical action. The source context for this page is fph-lan-ems, partner dashboard Offline Snapshot and Sync History, EMS LAN support routes, and the completed EMS LAN task history.
Scope
| Area | What this page covers |
|---|
| Product area | EMS LAN |
| Docs stage | Basics |
| Practical scope | snapshot export, file custody, schema metadata, import validation, warnings, and applied counts |
| Primary outcome | keep an event operating on a trusted local network when internet access is unreliable, then return offline work to the online dashboard with reviewable proof |
Routes and surfaces
| Route or surface | Why it matters | Verification proof |
|---|
/login | Surface, route, host, or integration context readers should have open while following this page. | Confirm the page, host, event, environment, or integration is the one currently being reviewed. |
/control-room | Surface, route, host, or integration context readers should have open while following this page. | Confirm the page, host, event, environment, or integration is the one currently being reviewed. |
/admin/:eventId/:surface | Surface, route, host, or integration context readers should have open while following this page. | Confirm the page, host, event, environment, or integration is the one currently being reviewed. |
/workspace/:eventId/:surface | Surface, route, host, or integration context readers should have open while following this page. | Confirm the page, host, event, environment, or integration is the one currently being reviewed. |
Page-specific records
| Record or contract | What it represents | Verification proof |
|---|
Local SQLite database | Record or contract family that can be read, exported, changed, imported, reconciled, or used as support evidence. | Keep the record ID, count, status, timestamp, or owner needed for another reviewer to verify the handoff. |
Bootstrap credentials | Record or contract family that can be read, exported, changed, imported, reconciled, or used as support evidence. | Keep the record ID, count, status, timestamp, or owner needed for another reviewer to verify the handoff. |
Imported events | Record or contract family that can be read, exported, changed, imported, reconciled, or used as support evidence. | Keep the record ID, count, status, timestamp, or owner needed for another reviewer to verify the handoff. |
Local sessions | Record or contract family that can be read, exported, changed, imported, reconciled, or used as support evidence. | Keep the record ID, count, status, timestamp, or owner needed for another reviewer to verify the handoff. |
Decision owners
| Audience | Responsibility | Verification proof |
|---|
Server operators | Reader group expected to make or review decisions from this page. | Make sure this group has the required access and escalation path before relying on the workflow. |
Event leads | Reader group expected to make or review decisions from this page. | Make sure this group has the required access and escalation path before relying on the workflow. |
LAN admins | Reader group expected to make or review decisions from this page. | Make sure this group has the required access and escalation path before relying on the workflow. |
Mental model
The safe way to use this page is to follow the record, not the screen. A screen, route, file, or response is useful only when staff can connect it to the actor who used it, the record it changed, and the proof that remains afterward.
Use this sequence before relying on the page:
- Identify the exact event, route, file, account, device, or record family.
- Confirm which system is the source of truth at this step.
- Check the role, local account, attendee account, machine token, or service caller.
- Make the narrowest action that matches the workflow.
- Verify the result where the next reviewer will look.
| Shared item | What it means | Verification proof |
|---|
| Snapshot file | Carries event data into or out of the offline environment. | Event ID, export time, format, file owner, and import history match. |
| Local SQLite records | Hold LAN-local check-in, claim, POS, inventory, HR, roster, communications, account, and token state. | Local counts are compared to online records after import. |
| Operator or device identity | Shows who acted in the local environment. | Local user, machine token, Android device, or server operator is named. |
| Exception notes | Explain manual decisions made while disconnected. | A later reviewer can identify what happened and who owns follow-up. |
Operating sequence
| Step | Action | Stop if |
|---|
| 1 | Confirm scope before acting. | The event, file, route, environment, user, or device is unclear. |
| 2 | Check authority before changing state. | The actor can view information but should not make this decision. |
| 3 | Review the visible option, file, route, or record effect. | The action affects access, money-adjacent records, public information, offline state, or external services without a reviewer. |
| 4 | Complete the action only after the expected result is known. | Staff cannot say what success and failure should look like. |
| 5 | Save handoff evidence. | The result exists only in memory, chat, or an unsafe screenshot. |

Verification
| Check | Evidence to keep |
|---|
| Scope check | Event ID, route family, file name, record ID, environment, account, or device name. |
| Actor check | Staff role, attendee account, local user, machine token, service caller, or external system. |
| Result check | Updated record, imported count, response body, audit entry, local note, sync-history row, or visible status. |
| Exception check | Warning, skipped row, validation error, denied permission, partial result, or fallback decision. |
| Handoff check | Named owner and next action for anything unresolved. |
Common mistakes
| Mistake | Why it causes problems | Recovery |
|---|
| Treating a visible screen as complete proof. | Screens may be filtered, stale, local-only, or scoped to one actor. | Check the underlying record, route evidence, sync history, or audit trail. |
| Acting without naming the actor. | Permissions and side effects depend on who or what made the request. | Repeat the check with the correct staff role, attendee account, local user, or service caller. |
| Skipping evidence because the action looked successful. | Support cannot distinguish success, partial success, retry, or workaround later. | Capture timestamp, record ID, result, and reviewer note before closeout. |
