# Create new Discovery

`POST /api/v1/discovery`

## Request body

- Discovery
  - `daemon_id` string, uuid, required — The daemon this entity refers to.
  - `discovery_type` union, required
    - object
      - `host_id` string, uuid, required — The host the daemon is running on.
      - `type` 'SelfReport', required
    - object
      - `host_naming_fallback` 'Ip' | 'BestService', required
      - `snmp_credentials` object — SNMP credentials for querying devices during discovery Server builds this mapping before initiating discovery
      - `subnet_ids` string[], nullable, required — Subnets to sweep. `null` sweeps every subnet on the network.
      - `type` 'Network', required
    - object
      - `host_id` string, uuid, required — The host the daemon is running on.
      - `host_naming_fallback` 'Ip' | 'BestService', required
      - `type` 'Docker', required
    - object — A one-shot verification of a single host: re-check the addresses and ports already recorded for it, rather than sweeping a subnet. Created by the server only (never via the API) and deleted once its session reaches a terminal phase, so it is not a discovery configuration anyone owns or sees in their scan list.
      - `host_id` string, uuid, required — ID of the host that the daemon is running on — same meaning as every other variant. The host being rescanned is `target_host_id`.
      - `ips` string[], required — Addresses to scan on that host.
      - `ports` PortType[] — Ports already known on that host, re-checked to confirm they are still open. Scanned in addition to the standard discovery set, so a rescan also surfaces newly-opened services.
        - `number` integer, required — TCP or UDP port number
        - `protocol` 'Udp' | 'Tcp', required — Transport protocol the port is open on.
        - `type` 'Ssh' | 'Telnet' | 'DnsUdp' | 'DnsTcp' | 'Samba' | 'Nfs' | 'Ftp' | 'Ipp' | 'LdpTcp' | 'LdpUdp' | 'Ldap' | 'Ldaps' | 'Kerberos' | 'Snmp' | 'SnmpAlt' | 'Rdp' | 'Ntp' | 'Sip' | 'SipTls' | 'Rtsp' | 'Dhcp' | 'Http' | 'MySql' | 'PostgreSQL' | 'MongoDB' | 'Redis' | 'MsSql' | 'Docker' | 'DockerTls' | 'Kubernetes' | 'RabbitMqMgmt' | 'Cassandra' | 'Elasticsearch' | 'InfluxDb' | 'CouchDb' | 'Kafka' | 'Http3000' | 'Http5000' | 'Http8080' | 'Http8081' | 'Http8082' | 'Http8888' | 'Http9000' | 'Https' | 'Https8443' | 'Https9443' | 'Https10443' | 'Mqtt' | 'MqttTls' | 'AMQP' | 'AMQPTls' | 'Wireguard' | 'OpenVPN' | 'BACnet' | 'JetDirect' | 'Custom' — Well-known port identifier. Auto-derived from number+protocol, so it is optional on create.
      - `settings` RescanSettings — Scan settings that apply to a single-host rescan. Deliberately narrower than [`ScanSettings`]: a rescan verifies a known host against a known port set, so the full-scan mechanism (`is_full_scan`, `full_scan_interval`) must not be expressible — promoting a rescan to a 65,535-port sweep defeats the feature. The remaining omissions are settings that cannot bind on a one-or-two address target.
        - `arp_retries` integer, nullable — ARP retry rounds. Matters more here than in a sweep: for a rescan, "did it answer" is the entire answer, so a missed round reads as a dead host.
        - `port_scan_batch_size` integer, nullable — Ports scanned concurrently per host.
        - `probe_raw_socket_ports` boolean — Whether to probe raw-socket ports 9100-9107. Correctness-affecting: with this off the scanner drops those ports from its results, so a printer's known JetDirect port would look like it had disappeared.
        - `scan_rate_pps` integer, nullable — Port scan probes per second. Operators lower this for fragile devices or noisy IDS, and a rescan must respect that as much as a discovery does.
        - `use_npcap_arp` boolean — On Windows, use Npcap broadcast ARP instead of SendARP.
      - `target_host_id` string, uuid, required — The host being rescanned.
      - `type` 'Rescan', required
    - object
      - `host_id` string, uuid, required — ID of the host that the daemon is running on
      - `host_naming_fallback` 'Ip' | 'BestService', required
      - `scan_settings` ScanSettings — Scan performance settings. Lives on the discovery entity. Numeric fields are `Option<T>` — `None` means "use daemon default". The daemon unwraps with defaults at point of use.
        - `arp_rate_pps` integer, nullable — ARP packets per second (default: 50)
        - `arp_retries` integer, nullable — ARP retry rounds for non-responsive targets (default: 2 = 3 total attempts)
        - `arp_scan_cutoff` integer, nullable — ARP scan cutoff prefix. Interfaced subnets larger than this prefix are truncated to this many IPs. Default: 15 (= /15, ~131K IPs). Lower values scan more IPs — increase arp_rate_pps accordingly.
        - `full_scan_interval` integer, nullable — Run a full 65k port scan every N scans. Other scans use a light port set. Default: 3. Value of 0 means never full scan. Value of 1 means every scan is full.
        - `is_full_scan` boolean — Whether this specific scan run should do a full 65k port scan. Set by the server before dispatching to the daemon — not user-configurable.
        - `max_discovery_duration` integer, nullable — Hard ceiling on how long a single discovery run may take, in seconds (default: 21600 = 6h). When hit, the run force-completes and any hosts still queued are left un-scanned until the next run. Raise this for very large networks that legitimately need more than the default window.
        - `port_scan_batch_size` integer, nullable — Ports scanned concurrently per host (default: 200, clamped 16-1000)
        - `probe_raw_socket_ports` boolean — Whether to probe raw-socket ports 9100-9107 (default: false). Disabled by default to prevent ghost printing on JetDirect printers.
        - `scan_rate_pps` integer, nullable — Port scan probes per second (default: 500)
        - `use_npcap_arp` boolean — On Windows, use Npcap broadcast ARP instead of SendARP (default: false)
      - `subnet_ids` string[], nullable, required — Subnets to scan. None = scan all interfaced subnets.
      - `type` 'Unified', required
  - `name` string, required — Human-facing name for this discovery.
  - `network_id` string, uuid, required — The network this entity belongs to.
  - `run_type` union, required
    - object
      - `cron_schedule` string, required — Cron expression deciding when the scan runs.
      - `enabled` boolean, required — Whether the schedule is active.
      - `last_run` string, date-time, nullable — When the scan last ran.
      - `timezone` string, nullable — IANA timezone for cron evaluation, e.g. "America/New_York". None = UTC.
      - `type` 'Scheduled', required
    - object — Historical discovery runs are created by the server and cannot be submitted via API
      - `results` DiscoveryUpdatePayload, required — Progress update from daemon to server during discovery
        - `daemon_id` string, uuid, required — The daemon this entity refers to.
        - `discovery_id` string, uuid, nullable — The discovery configuration this session belongs to. Always enriched server-side; daemons do not send this field.
        - `discovery_type` union, required
          - object
            - `host_id` string, uuid, required — The host the daemon is running on.
            - `type` 'SelfReport', required
          - object
            - `host_naming_fallback` 'Ip' | 'BestService', required
            - `snmp_credentials` object — SNMP credentials for querying devices during discovery Server builds this mapping before initiating discovery
            - `subnet_ids` string[], nullable, required — Subnets to sweep. `null` sweeps every subnet on the network.
            - `type` 'Network', required
          - object
            - `host_id` string, uuid, required — The host the daemon is running on.
            - `host_naming_fallback` 'Ip' | 'BestService', required
            - `type` 'Docker', required
          - object — A one-shot verification of a single host: re-check the addresses and ports already recorded for it, rather than sweeping a subnet. Created by the server only (never via the API) and deleted once its session reaches a terminal phase, so it is not a discovery configuration anyone owns or sees in their scan list.
            - `host_id` string, uuid, required — ID of the host that the daemon is running on — same meaning as every other variant. The host being rescanned is `target_host_id`.
            - `ips` string[], required — Addresses to scan on that host.
            - `ports` PortType[] — Ports already known on that host, re-checked to confirm they are still open. Scanned in addition to the standard discovery set, so a rescan also surfaces newly-opened services.
              - …

Deliberately narrower than [`ScanSettings`]: a rescan verifies a known host against a known port set, so the full-scan mechanism (`is_full_scan`, `full_scan_interval`) must not be expressible — promoting a rescan to a 65,535-port sweep defeats the feature.

              - …
            - `target_host_id` string, uuid, required — The host being rescanned.
            - `type` 'Rescan', required
          - object
            - `host_id` string, uuid, required — ID of the host that the daemon is running on
            - `host_naming_fallback` 'Ip' | 'BestService', required
            - `scan_settings` ScanSettings — Scan performance settings. Lives on the discovery entity. Numeric fields are `Option<T>` — `None` means "use daemon default". The daemon unwraps with defaults at point of use.
              - …
            - `subnet_ids` string[], nullable, required — Subnets to scan. None = scan all interfaced subnets.
            - `type` 'Unified', required
        - `error` string, nullable — Failure message, when the run did not complete.
        - `estimated_remaining_secs` integer, nullable — Rough estimate of the time left, in seconds.
        - `finished_at` string, date-time, nullable — When the run finished. `null` while it is still going.
        - `hosts_discovered` integer, nullable — Hosts found so far.
        - `network_id` string, uuid, required — The network this entity belongs to.
        - `phase` 'AwaitingSnapshot' | 'Queued' | 'Pending' | 'Starting' | 'Started' | 'Scanning' | 'Complete' | 'Failed' | 'Cancelled', required
        - `progress` integer, required — Completion of the current phase, from 0 to 1.
        - `scanned` ScannedEntityIds — Canonical IDs of entities scanned in a discovery session. Populated daemon-side at terminal phase from `EntityBuffer`'s `Created` entries. Travels with the terminal `DiscoveryUpdatePayload` to the server, rides the in-memory `EntityOperation::Created` event published for the historical Discovery row (the event scope carries `Entity::Discovery` with the full struct, including `run_type::Historical { results }`), then is stripped before persisting into the historical Discovery row's JSONB (see the `SqlValue::RunType` bind_value handler in `backend/src/server/shared/storage/generic.rs`). Per-entity-service subscribers extract `results.scanned` from the in-memory event and call `DiscoveryFkUpdater::update_discovery_fks` to backfill `last_discovery_id` / `first_discovery_id` on the matched rows. Naming: `scanned_*` because the daemon scans entities — some submissions match existing rows (refresh), others insert new rows. Both populate the EntityBuffer with canonical (server-assigned) IDs.
          - `binding_ids` string[] — Service bindings touched by this discovery.
          - `host_ids` string[] — Hosts touched by this discovery.
          - `interface_ids` string[] — Interfaces touched by this discovery.
          - `ip_address_ids` string[] — IP addresses touched by this discovery.
          - `port_ids` string[] — Ports touched by this discovery.
          - `service_ids` string[] — Services touched by this discovery.
          - `subnet_ids` string[] — Subnets touched by this discovery.
          - `vlan_ids` string[] — VLANs touched by this discovery.
        - `session_id` string, uuid, required — The discovery run this update belongs to.
        - `started_at` string, date-time, nullable — When the run started.
        - `warnings` DiscoveryWarning[] — Non-fatal findings from a completed run — one per occurrence, each carrying the code that identifies it and the detail that fills the sentence. Unlike `error`, these do not mark the run failed. Read through [`deserialize_warnings`] rather than the derived impl, which is what keeps historical records and pre-coded daemons rendering: both send bare strings here, and both land as `Unknown` carrying that text instead of failing the whole payload.
          - union — A single non-fatal finding from one discovery run, about one device, neighbour, or the scan itself. Serialized with the code as the tag, so the generated TypeScript is a discriminated union the UI can switch on exhaustively. The derived `Deserialize` reads that shape; the leniency that keeps historical records and pre-coded daemons working lives in [`deserialize_warnings`], which is applied at the one field that holds these.
            - object — The interface *set* was cut short, so interfaces are genuinely missing.
              - …
            - object — The set was complete and only the attribute columns fell short, so nothing is missing — some descriptions or speeds are just blank. Kept apart from the above because reporting this as possible data loss sends people hunting for interfaces that were never absent.
              - …
            - object — Stopped at our own entry cap. The device is fine and larger than we read.
              - …
            - object — The device does not implement this MIB. Not a fault, and no later scan will change it.
              - …
            - object — The agent answered out of step with what was asked — stale or non-advancing responses.
              - …
            - object — A partial read whose rows are thrown away rather than recorded, so the device contributes nothing for this group however much it answered.
              - …
            - object — A partial read whose rows were recorded as far as they got.
              - …
            - object — Nothing came back for the root of the bridge MIB, which switches commonly do not implement.
              - …
            - object — Nothing came back at all, and the device stopped answering rather than reporting empty.
              - …
            - object — The device published a count, and the read ended before reaching it.
              - …
            - object — The device published a count, the read finished, and it came up short anyway.
              - …
            - object — The device declared the capability, and the read ended without returning any.
              - …
            - object — The device declared the capability, the read finished, and it returned none.
              - …
            - object — Neighbours whose local port matched no interface, so they were discarded entirely.
              - …
            - object — Neighbours whose local port could not be identified but did match an interface number, so they are drawn against a port that may be the wrong one.
              - …
            - object — The column carrying the identifier stopped early, so a rescan may recover these.
              - …
            - object — Rows that never appeared in the identifying column at all.
              - …
            - object — Neighbours listed and then never given an identifier.
              - …
            - object — The identifying column held a value of a type it cannot hold.
              - …
            - object — The record's position in the neighbour table could not be read.
              - …
            - object — SNMP answered and every table came back empty.
              - …
            - object — The device answered correctly and persisting its VLANs failed.
              - …
            - object — The credential's address is not on any subnet this scan covers.
              - …
            - object — Nothing answered at the credential's address during the scan.
              - …
            - object — The port the credential needs was not open, so it was never tried.
              - …
            - object — The credential was refused.
              - …
            - object — The credential is incomplete and could not be used.
              - …
            - object — TLS could not be negotiated.
              - …
            - object — Something answered that is not the expected service.
              - …
            - object — Authenticated, then failed while collecting.
              - …
            - object — Authenticated, then ran out of time while collecting.
              - …
            - object — Nothing was reachable at the address.
              - …
            - object — The attempt timed out before anything answered.
              - …
            - object — The run hit its global time limit, with an estimate of the work left.
              - …
            - object — The run hit its global time limit, with no usable estimate.
              - …
            - object — The advertised identifier matches no host on this network.
              - …
            - object — The advertised identifier matches several hosts, so none can be picked.
              - …
            - object — The far end resolved, and its port id is of a subtype there is no lookup for.
              - …
            - object — The far end resolved, and none of its ports matches the advertised port id.
              - …
            - object — The far end resolved, and several of its ports match, so it identifies none.
              - …
            - object — The run produced more warnings than the scan record holds. Emitted rather than dropping the tail silently — a list that simply stops reads as though that was all of them.
              - …
            - object — A warning this binary does not recognise: a bare string from a historical record or a pre-coded daemon, or a code from a newer one. Carries the original text so scan history keeps rendering; the code itself is what reaches the metric, never `detail`.
              - …
      - `type` 'Historical', required
    - object
      - `last_run` string, date-time, nullable — When the scan last ran.
      - `type` 'AdHoc', required
  - `tags` string[], required — Tags assigned to this entity.
  - `created_at` string, date-time, required — When this record was first created.
  - `force_full_scan` boolean — When true, the next scan will be a full port scan regardless of interval
  - `id` string, uuid, required — Server-assigned unique identifier.
  - `integration_targets` IntegrationTarget[], required — Per-daemon integration targeting: which integrations run on this daemon, and on which IPs. Delivered via the init command at registration and editable via the discovery modal. This is the single home for cred↔IP targeting; it replaces the global `credential.target_ips` (race-prone, consumed once). One-shot: a target is offered to the daemon until a scan completes successfully, then dropped by [`Discovery::apply_successful_scan`]. Credentials that earned a durable home during the scan keep being retried from there — `host_credentials` for one that probed successfully, `network_credentials` for a broadcast one (see [`Discovery::take_network_scope_credential_ids`]).
    - union — Per-daemon integration targeting, stored on the `Discovery` entity and delivered via the init command at registration. Each entry references exactly one stored credential and says where it applies on this daemon. This is the single home for cred↔IP targeting — it replaces the global, race-prone `credential.target_ips`. The variants ARE the scopes; their strum [`Target`] discriminants are the capability enum that `CredentialType::targets()` returns and validates against (single source of truth). Every target carries a real `credential_id` — there is no credential-less branch and no nil sentinel; a local socket is just a credential whose type targets only the daemon host.
      - object — The daemon's own host — realized as a 127.0.0.1 IP-override (e.g. a local Docker/Podman socket, or any credential the user pins to the daemon host without naming its IP).
        - `credential_id` string, uuid, required — Credential to use on the daemon host.
        - `scope` 'DaemonHost', required
      - object — All hosts on the network — a broadcast default credential.
        - `credential_id` string, uuid, required — Credential to use across the network.
        - `scope` 'Network', required
      - object — Specific host IPs — one IP-override per address.
        - `credential_id` string, uuid, required — Credential to use on the listed addresses.
        - `ips` string[], required — The host addresses this credential applies to.
        - `scope` 'Hosts', required
  - `scan_count` integer — Number of completed scans (incremented by server on session completion)
  - `updated_at` string, date-time, required — When this record was last modified.

## Response `200`

      - object
        - `host_id` string, uuid, required — The host the daemon is running on.
        - `type` 'SelfReport', required
      - object
        - `host_naming_fallback` 'Ip' | 'BestService', required
        - `snmp_credentials` object — SNMP credentials for querying devices during discovery Server builds this mapping before initiating discovery
        - `subnet_ids` string[], nullable, required — Subnets to sweep. `null` sweeps every subnet on the network.
        - `type` 'Network', required
      - object
        - `host_id` string, uuid, required — The host the daemon is running on.
        - `host_naming_fallback` 'Ip' | 'BestService', required
        - `type` 'Docker', required
      - object — A one-shot verification of a single host: re-check the addresses and ports already recorded for it, rather than sweeping a subnet. Created by the server only (never via the API) and deleted once its session reaches a terminal phase, so it is not a discovery configuration anyone owns or sees in their scan list.
        - `host_id` string, uuid, required — ID of the host that the daemon is running on — same meaning as every other variant. The host being rescanned is `target_host_id`.
        - `ips` string[], required — Addresses to scan on that host.
        - `ports` PortType[] — Ports already known on that host, re-checked to confirm they are still open. Scanned in addition to the standard discovery set, so a rescan also surfaces newly-opened services.
          - `number` integer, required — TCP or UDP port number
          - `protocol` 'Udp' | 'Tcp', required — Transport protocol the port is open on.
          - `type` 'Ssh' | 'Telnet' | 'DnsUdp' | 'DnsTcp' | 'Samba' | 'Nfs' | 'Ftp' | 'Ipp' | 'LdpTcp' | 'LdpUdp' | 'Ldap' | 'Ldaps' | 'Kerberos' | 'Snmp' | 'SnmpAlt' | 'Rdp' | 'Ntp' | 'Sip' | 'SipTls' | 'Rtsp' | 'Dhcp' | 'Http' | 'MySql' | 'PostgreSQL' | 'MongoDB' | 'Redis' | 'MsSql' | 'Docker' | 'DockerTls' | 'Kubernetes' | 'RabbitMqMgmt' | 'Cassandra' | 'Elasticsearch' | 'InfluxDb' | 'CouchDb' | 'Kafka' | 'Http3000' | 'Http5000' | 'Http8080' | 'Http8081' | 'Http8082' | 'Http8888' | 'Http9000' | 'Https' | 'Https8443' | 'Https9443' | 'Https10443' | 'Mqtt' | 'MqttTls' | 'AMQP' | 'AMQPTls' | 'Wireguard' | 'OpenVPN' | 'BACnet' | 'JetDirect' | 'Custom' — Well-known port identifier. Auto-derived from number+protocol, so it is optional on create.
        - `settings` RescanSettings — Scan settings that apply to a single-host rescan. Deliberately narrower than [`ScanSettings`]: a rescan verifies a known host against a known port set, so the full-scan mechanism (`is_full_scan`, `full_scan_interval`) must not be expressible — promoting a rescan to a 65,535-port sweep defeats the feature. The remaining omissions are settings that cannot bind on a one-or-two address target.
          - `arp_retries` integer, nullable — ARP retry rounds. Matters more here than in a sweep: for a rescan, "did it answer" is the entire answer, so a missed round reads as a dead host.
          - `port_scan_batch_size` integer, nullable — Ports scanned concurrently per host.
          - `probe_raw_socket_ports` boolean — Whether to probe raw-socket ports 9100-9107. Correctness-affecting: with this off the scanner drops those ports from its results, so a printer's known JetDirect port would look like it had disappeared.
          - `scan_rate_pps` integer, nullable — Port scan probes per second. Operators lower this for fragile devices or noisy IDS, and a rescan must respect that as much as a discovery does.
          - `use_npcap_arp` boolean — On Windows, use Npcap broadcast ARP instead of SendARP.
        - `target_host_id` string, uuid, required — The host being rescanned.
        - `type` 'Rescan', required
      - object
        - `host_id` string, uuid, required — ID of the host that the daemon is running on
        - `host_naming_fallback` 'Ip' | 'BestService', required
        - `scan_settings` ScanSettings — Scan performance settings. Lives on the discovery entity. Numeric fields are `Option<T>` — `None` means "use daemon default". The daemon unwraps with defaults at point of use.
          - `arp_rate_pps` integer, nullable — ARP packets per second (default: 50)
          - `arp_retries` integer, nullable — ARP retry rounds for non-responsive targets (default: 2 = 3 total attempts)
          - `arp_scan_cutoff` integer, nullable — ARP scan cutoff prefix. Interfaced subnets larger than this prefix are truncated to this many IPs. Default: 15 (= /15, ~131K IPs). Lower values scan more IPs — increase arp_rate_pps accordingly.
          - `full_scan_interval` integer, nullable — Run a full 65k port scan every N scans. Other scans use a light port set. Default: 3. Value of 0 means never full scan. Value of 1 means every scan is full.
          - `is_full_scan` boolean — Whether this specific scan run should do a full 65k port scan. Set by the server before dispatching to the daemon — not user-configurable.
          - `max_discovery_duration` integer, nullable — Hard ceiling on how long a single discovery run may take, in seconds (default: 21600 = 6h). When hit, the run force-completes and any hosts still queued are left un-scanned until the next run. Raise this for very large networks that legitimately need more than the default window.
          - `port_scan_batch_size` integer, nullable — Ports scanned concurrently per host (default: 200, clamped 16-1000)
          - `probe_raw_socket_ports` boolean — Whether to probe raw-socket ports 9100-9107 (default: false). Disabled by default to prevent ghost printing on JetDirect printers.
          - `scan_rate_pps` integer, nullable — Port scan probes per second (default: 500)
          - `use_npcap_arp` boolean — On Windows, use Npcap broadcast ARP instead of SendARP (default: false)
        - `subnet_ids` string[], nullable, required — Subnets to scan. None = scan all interfaced subnets.
        - `type` 'Unified', required
    - `name` string, required — Human-facing name for this discovery.
    - `network_id` string, uuid, required — The network this entity belongs to.
    - `run_type` union, required
      - object
        - `cron_schedule` string, required — Cron expression deciding when the scan runs.
        - `enabled` boolean, required — Whether the schedule is active.
        - `last_run` string, date-time, nullable — When the scan last ran.
        - `timezone` string, nullable — IANA timezone for cron evaluation, e.g. "America/New_York". None = UTC.
        - `type` 'Scheduled', required
      - object — Historical discovery runs are created by the server and cannot be submitted via API
        - `results` DiscoveryUpdatePayload, required — Progress update from daemon to server during discovery
          - `daemon_id` string, uuid, required — The daemon this entity refers to.
          - `discovery_id` string, uuid, nullable — The discovery configuration this session belongs to. Always enriched server-side; daemons do not send this field.
          - `discovery_type` union, required
            - object
              - …

              - …
            - object
              - …
            - object — A one-shot verification of a single host: re-check the addresses and ports already recorded for it, rather than sweeping a subnet. Created by the server only (never via the API) and deleted once its session reaches a terminal phase, so it is not a discovery configuration anyone owns or sees in their scan list.

            - object
              - …
          - `error` string, nullable — Failure message, when the run did not complete.
          - `estimated_remaining_secs` integer, nullable — Rough estimate of the time left, in seconds.
          - `finished_at` string, date-time, nullable — When the run finished. `null` while it is still going.
          - `hosts_discovered` integer, nullable — Hosts found so far.
          - `network_id` string, uuid, required — The network this entity belongs to.
          - `phase` 'AwaitingSnapshot' | 'Queued' | 'Pending' | 'Starting' | 'Started' | 'Scanning' | 'Complete' | 'Failed' | 'Cancelled', required
          - `progress` integer, required — Completion of the current phase, from 0 to 1.
          - `scanned` ScannedEntityIds — Canonical IDs of entities scanned in a discovery session. Populated daemon-side at terminal phase from `EntityBuffer`'s `Created` entries. Travels with the terminal `DiscoveryUpdatePayload` to the server, rides the in-memory `EntityOperation::Created` event published for the historical Discovery row (the event scope carries `Entity::Discovery` with the full struct, including `run_type::Historical { results }`), then is stripped before persisting into the historical Discovery row's JSONB (see the `SqlValue::RunType` bind_value handler in `backend/src/server/shared/storage/generic.rs`). Per-entity-service subscribers extract `results.scanned` from the in-memory event and call `DiscoveryFkUpdater::update_discovery_fks` to backfill `last_discovery_id` / `first_discovery_id` on the matched rows. Naming: `scanned_*` because the daemon scans entities — some submissions match existing rows (refresh), others insert new rows. Both populate the EntityBuffer with canonical (server-assigned) IDs.
            - `binding_ids` string[] — Service bindings touched by this discovery.
            - `host_ids` string[] — Hosts touched by this discovery.
            - `interface_ids` string[] — Interfaces touched by this discovery.
            - `ip_address_ids` string[] — IP addresses touched by this discovery.
            - `port_ids` string[] — Ports touched by this discovery.
            - `service_ids` string[] — Services touched by this discovery.
            - `subnet_ids` string[] — Subnets touched by this discovery.
            - `vlan_ids` string[] — VLANs touched by this discovery.
          - `session_id` string, uuid, required — The discovery run this update belongs to.
          - `started_at` string, date-time, nullable — When the run started.
          - `warnings` DiscoveryWarning[] — Non-fatal findings from a completed run — one per occurrence, each carrying the code that identifies it and the detail that fills the sentence. Unlike `error`, these do not mark the run failed. Read through [`deserialize_warnings`] rather than the derived impl, which is what keeps historical records and pre-coded daemons rendering: both send bare strings here, and both land as `Unknown` carrying that text instead of failing the whole payload.
            - union — A single non-fatal finding from one discovery run, about one device, neighbour, or the scan itself. Serialized with the code as the tag, so the generated TypeScript is a discriminated union the UI can switch on exhaustively. The derived `Deserialize` reads that shape; the leniency that keeps historical records and pre-coded daemons working lives in [`deserialize_warnings`], which is applied at the one field that holds these.
              - …
        - `type` 'Historical', required
      - object
        - `last_run` string, date-time, nullable — When the scan last ran.
        - `type` 'AdHoc', required
    - `tags` string[], required — Tags assigned to this entity.
    - `created_at` string, date-time, required — When this record was first created.
    - `force_full_scan` boolean — When true, the next scan will be a full port scan regardless of interval
    - `id` string, uuid, required — Server-assigned unique identifier.
    - `integration_targets` IntegrationTarget[], required — Per-daemon integration targeting: which integrations run on this daemon, and on which IPs. Delivered via the init command at registration and editable via the discovery modal. This is the single home for cred↔IP targeting; it replaces the global `credential.target_ips` (race-prone, consumed once). One-shot: a target is offered to the daemon until a scan completes successfully, then dropped by [`Discovery::apply_successful_scan`]. Credentials that earned a durable home during the scan keep being retried from there — `host_credentials` for one that probed successfully, `network_credentials` for a broadcast one (see [`Discovery::take_network_scope_credential_ids`]).
      - union — Per-daemon integration targeting, stored on the `Discovery` entity and delivered via the init command at registration. Each entry references exactly one stored credential and says where it applies on this daemon. This is the single home for cred↔IP targeting — it replaces the global, race-prone `credential.target_ips`. The variants ARE the scopes; their strum [`Target`] discriminants are the capability enum that `CredentialType::targets()` returns and validates against (single source of truth). Every target carries a real `credential_id` — there is no credential-less branch and no nil sentinel; a local socket is just a credential whose type targets only the daemon host.
        - object — The daemon's own host — realized as a 127.0.0.1 IP-override (e.g. a local Docker/Podman socket, or any credential the user pins to the daemon host without naming its IP).
          - `credential_id` string, uuid, required — Credential to use on the daemon host.
          - `scope` 'DaemonHost', required
        - object — All hosts on the network — a broadcast default credential.
          - `credential_id` string, uuid, required — Credential to use across the network.
          - `scope` 'Network', required
        - object — Specific host IPs — one IP-override per address.
          - `credential_id` string, uuid, required — Credential to use on the listed addresses.
          - `ips` string[], required — The host addresses this credential applies to.
          - `scope` 'Hosts', required
    - `scan_count` integer — Number of completed scans (incremented by server on session completion)
    - `updated_at` string, date-time, required — When this record was last modified.
  - `error` string, nullable — Human-readable failure message. Omitted on success.
  - `meta` ApiMeta, required — API metadata included in all responses
    - `api_version` integer, required — API version (integer, increments on breaking changes)
    - `server_version` string, required — Server version (semver)
  - `success` boolean, required — `true` when the request succeeded. `false` responses carry `error` instead of `data`.
