+# RTSPS and TLS certificates
+
+This guide explains how Kerberos Agent connects to an IP camera over RTSPS,
+how to issue a camera certificate with a private CA, and how to validate the
+complete trust path. It also explains why some apparently corrupted trust
+bundles can still allow a connection.
+
+The camera-specific steps were verified with a Bosch FLEXIDOME micro 3100i.
+Other Bosch firmware versions may use different labels or ports.
+
+The commands were tested with Smallstep CLI `0.30.6` and OpenSSL `3.5.6` on
+Debian. Check `step certificate sign --help` when using an older Smallstep CLI.
+The OpenSSL isolation flags `-no-CApath` and `-no-CAstore` require a version that
+lists them in `openssl s_client -help`.
+
+## Tested configuration
+
+| Setting | Value |
+| --- | --- |
+| Camera | Bosch FLEXIDOME micro 3100i |
+| Example camera address | `10.0.30.11` |
+| RTSPS port | `9554` |
+| Main stream | `rtsps://<user>:<password>@10.0.30.11:9554/?inst=1` |
+| Sub stream | `rtsps://<user>:<password>@10.0.30.11:9554/?inst=2` |
+| Certificate SAN | `IP Address:10.0.30.11` |
+| Bosch certificate usage | `HTTPS` |
+| Agent trust input | Issuing intermediate plus root CA |
+
+Replace the example address and certificate names throughout this guide. Keep
+camera credentials out of source control and percent-encode reserved URL
+characters in usernames and passwords.
+
+## Mental model
+
+### RTSPS, SRTSP, TLS, and SRTP
+
+- The standard URL scheme is `rtsps://`. Do not use `srtsp://`.
+- Bosch interfaces and documentation may use SRTSP or Secure RTSP as product
+  terminology.
+- RTSPS carries the RTSP control connection over TLS. With gortsplib, media is
+  normally interleaved over the same TCP/TLS connection for this camera.
+- SRTP is a separate media protection mechanism and is negotiated only when the
+  camera advertises an appropriate secure RTP profile.
+
+Encryption alone does not prove which camera the Agent reached. Verified TLS
+also checks that:
+
+1. The camera certificate is signed by a trusted authority.
+2. The certificate is valid at the current time.
+3. The URL host matches a certificate Subject Alternative Name (SAN).
+
+Modern Go verification uses SANs for identity. A Common Name alone is not
+sufficient. Connecting to `10.0.30.11` requires an IP SAN with that exact value,
+not `DNS:10.0.30.11` and not only a device-name DNS SAN.
+
+### Agent behavior
+
+Kerberos Agent uses gortsplib for RTSP and RTSPS. With the normal configuration,
+gortsplib receives a nil custom TLS configuration and Go performs standard
+certificate and hostname verification with the process trust pool.
+
+`AGENT_CAPTURE_IPCAMERA_RTSPS_INSECURE=true` is an explicit escape hatch that
+sets `InsecureSkipVerify` for camera clients. It should be false in a verified
+deployment.
+
+## Communication and certificate flow
+
+The certificate is used during the TLS handshake, before the first RTSP command
+is exchanged. It is not attached to `DESCRIBE`, `SETUP`, or `PLAY`, and the CA
+trust bundle is never sent to the camera.
+
+```mermaid
+sequenceDiagram
+  participant Agent as Kerberos Agent
+  participant Trust as Go trust pool
+  participant Camera as Camera RTSPS :9554
+
+  Agent->>Trust: Load system roots and append AGENT_CAPTURE_IPCAMERA_RTSPS_CA_FILE
+  Agent->>Camera: Open TCP connection
+  Agent->>Camera: Send TLS ClientHello
+  Camera-->>Agent: Send TLS ServerHello and camera certificate
+  Agent->>Trust: Verify chain, validity, serverAuth, and URL host against SAN
+  Trust-->>Agent: Accept or reject the camera identity
+  Agent->>Camera: Complete TLS handshake
+  Note over Agent,Camera: All following traffic is encrypted by TLS
+  Agent->>Camera: DESCRIBE with RTSP authentication
+  Camera-->>Agent: Return SDP and available media tracks
+  Agent->>Camera: SETUP selected video and audio tracks over TCP
+  Agent->>Camera: PLAY
+  Camera-->>Agent: Send interleaved RTP and RTCP media over TLS
+```
+
+The files and keys have distinct roles:
+
+| Material | Location | Purpose | Sent over the connection |
+| --- | --- | --- | --- |
+| Camera leaf certificate | Camera | Identifies the camera and binds its public key to its SAN | Yes, by the camera during the TLS handshake |
+| Camera private key | Camera | Proves that the camera owns the presented certificate | No |
+| Intermediate and root CA PEM bundle | Agent | Lets Go build and trust the camera certificate chain | No |
+| RTSP username and password | Agent configuration or URL | Authenticates the Agent to the RTSP service after TLS succeeds | An authentication response is sent inside TLS; its form depends on the RTSP authentication method |
+
+For an `rtsps://` URL, the Agent parses the URL and gives gortsplib the host and
+TLS settings. gortsplib opens the TCP connection and starts TLS. Go compares the
+certificate presented by the camera with the local trust pool, checks its
+validity period and server usage, and matches the URL hostname or IP address to
+the certificate SAN. Only a successful handshake creates the encrypted channel
+needed for the RTSP exchange.
+
+The Agent then sends `DESCRIBE`, selects the advertised video and audio tracks,
+sends `SETUP`, and starts delivery with `PLAY`. For the tested camera, gortsplib
+uses interleaved TCP, so the RTSP control messages and RTP/RTCP media remain
+inside the same encrypted TLS connection. Main stream, sub stream, and enabled
+audio backchannel clients each establish and verify their own connection.
+
+If certificate verification fails, the TLS handshake does not complete and no
+usable RTSP session is established. Setting
+`AGENT_CAPTURE_IPCAMERA_RTSPS_INSECURE=true` keeps traffic encrypted but skips
+certificate-chain and hostname verification, so an attacker could impersonate
+the camera. It is not equivalent to trusting the camera certificate.
+
+## Decide the certificate identity first
+
+Choose the stable name used in every Agent URL before creating the certificate:
+
+- For an IP URL, add that address as an IP SAN.
+- For a DNS URL, add the exact hostname as a DNS SAN.
+- Add both when clients legitimately use both forms.
+
+A certificate stops matching if the camera IP changes. Use a static address,
+DHCP reservation, or stable DNS name.
+
+## Configure RTSPS in the Bosch UI
+
+1. Sign in to the camera as an administrator.
+2. Open **Configuration**.
+3. Open **Network > Network Services**.
+4. Enable **RTSPS**.
+5. Confirm port `9554`, or record the configured alternative.
+6. Click **Set**.
+
+RTSP on port `554` and RTSPS on port `9554` are separate services. Enabling
+RTSPS does not make an `rtsp://` URL secure.
+
+## Generate the private key and CSR on the camera
+
+Keeping the TLS private key on the camera avoids exporting it to an operator
+workstation or deployment system.
+
+1. Open **Service > Certificates**.
+2. Click **Add**.
+3. Select **Generate signing request**.
+4. Select `RSA 2048bit` or the stronger option supported by all clients.
+5. Enter a unique file name, such as `agent-rtsps`.
+6. Enter a descriptive Common Name and any required organization fields.
+7. Click **Generate**.
+8. Download the resulting CSR from the certificate table.
+
+On the tested firmware, this form contains no SAN field. The downloaded CSR
+therefore has no IP SAN. The CA must add the SAN while signing.
+
+Inspect the CSR before signing:
+
+```bash
+openssl req -in camera.csr.pem -noout -verify -subject
+openssl req -in camera.csr.pem -noout -text
+```
+
+The first command must report `Certificate request self-signature verify OK`.
+An absent `Subject Alternative Name` section is expected for this firmware.
+
+## Prepare Smallstep
+
+Use an existing organizational CA when one is available. Creating a new CA
+creates a new long-lived trust domain that must be distributed, protected,
+backed up, and eventually rotated.
+
+### Install the CLI on Debian amd64
+
+```bash
+curl -fsSL \
+  https://dl.smallstep.com/cli/docs-ca-install/latest/step-cli_amd64.deb \
+  -o /tmp/step-cli_amd64.deb
+sudo dpkg -i /tmp/step-cli_amd64.deb
+rm /tmp/step-cli_amd64.deb
+step version
+```
+
+Use the official package matching the host architecture on other systems.
+
+### Create a dedicated offline CA
+
+Skip this section when using an existing CA.
+
+```bash
+umask 077
+mkdir -p "$HOME/.step/secrets" "$HOME/.step/camera"
+
+openssl rand -base64 48 > "$HOME/.step/secrets/camera_ca_password"
+chmod 600 "$HOME/.step/secrets/camera_ca_password"
+
+step ca init \
+  --pki \
+  --name "UUG Camera CA" \
+  --password-file "$HOME/.step/secrets/camera_ca_password"
+```
+
+This produces:
+
+```text
+$HOME/.step/certs/root_ca.crt
+$HOME/.step/certs/intermediate_ca.crt
+$HOME/.step/secrets/root_ca_key
+$HOME/.step/secrets/intermediate_ca_key
+$HOME/.step/secrets/camera_ca_password
+```
+
+The files under `secrets/` are sensitive. Keep them mode `600`, never commit
+them, and back them up to encrypted persistent storage. A devcontainer can be
+rebuilt or deleted; it is not sufficient as the only CA backup.
+
+## Add the SAN while signing
+
+Copy the camera CSR into a protected working directory:
+
+```bash
+cp camera.csr.pem "$HOME/.step/camera/camera.csr.pem"
+```
+
+Create `$HOME/.step/camera/bosch-rtsps.tpl`:
+
+```json
+{
+  "subject": {
+    "commonName": {{ toJson .Insecure.CR.Subject.CommonName }}
+  },
+  "ipAddresses": ["10.0.30.11"],
+  "keyUsage": ["keyEncipherment", "digitalSignature"],
+  "extKeyUsage": ["serverAuth", "clientAuth"]
+}
+```
+
+The template preserves the camera CSR public key, sets the IP identity, and
+creates a TLS leaf rather than a CA certificate.
+
+Sign it with a validity period that ends before the intermediate CA expires.
+A one-year leaf is preferable to a ten-year leaf when automated renewal is
+available:
+
+```bash
+step certificate sign \
+  --template "$HOME/.step/camera/bosch-rtsps.tpl" \
+  --bundle \
+  --not-after 8760h \
+  --password-file "$HOME/.step/secrets/camera_ca_password" \
+  "$HOME/.step/camera/camera.csr.pem" \
+  "$HOME/.step/certs/intermediate_ca.crt" \
+  "$HOME/.step/secrets/intermediate_ca_key" \
+  > "$HOME/.step/camera/bosch-rtsps-chain.pem"
+```
+
+For an online `step-ca`, do not assume `step ca sign` accepts a `--san` flag. It
+does not. Authorize SANs in the one-time token or configure a provisioner
+template that produces the required SANs.
+
+## Validate before upload
+
+Inspect the leaf certificate, which is the first PEM block in the chain file:
+
+```bash
+openssl x509 \
+  -in "$HOME/.step/camera/bosch-rtsps-chain.pem" \
+  -noout -subject -issuer -dates -ext subjectAltName -ext extendedKeyUsage
+```
+
+Confirm the SAN separately because some OpenSSL versions display only the last
+requested extension:
+
+```bash
+openssl x509 \
+  -in "$HOME/.step/camera/bosch-rtsps-chain.pem" \
+  -noout -ext subjectAltName
+```
+
+Verify the path and IP identity:
+
+```bash
+openssl verify \
+  -CAfile "$HOME/.step/certs/root_ca.crt" \
+  -untrusted "$HOME/.step/certs/intermediate_ca.crt" \
+  -verify_ip 10.0.30.11 \
+  "$HOME/.step/camera/bosch-rtsps-chain.pem"
+```
+
+Confirm that the signed leaf uses the exact public key from the camera CSR:
+
+```bash
+csr_key=$(
+  openssl req -in "$HOME/.step/camera/camera.csr.pem" -pubkey -noout |
+    openssl pkey -pubin -outform DER 2>/dev/null |
+    sha256sum | cut -d' ' -f1
+)
+
+cert_key=$(
+  openssl x509 -in "$HOME/.step/camera/bosch-rtsps-chain.pem" -pubkey -noout |
+    openssl pkey -pubin -outform DER 2>/dev/null |
+    sha256sum | cut -d' ' -f1
+)
+
+test "$csr_key" = "$cert_key"
+```
+
+Do not upload a certificate when any of these checks fail.
+
+## Upload and assign the certificate
+
+1. Return to **Service > Certificates**.
+2. Click **Add > Upload certificate**.
+3. Select the leaf-plus-intermediate PEM chain.
+4. Click **Upload** and wait for `100%`.
+5. Confirm that the former CSR row is now a `Certificate`.
+6. Confirm that the key icon is present. It proves that the camera associated
+   the certificate with its retained private key.
+7. Open the new certificate's **Usage** selector.
+8. Select only **HTTPS**.
+9. Leave **CBS client** assigned to the original Bosch `DeviceCertificate`.
+10. Click **Set** and wait for the table to reload.
+
+On the tested firmware, there is no separate SRTSP usage. RTSPS presents the
+certificate assigned to HTTPS. Reassigning HTTPS therefore changes both the
+web interface and RTSPS certificate.
+
+After saving, the expected split is:
+
+| Certificate | Usage |
+| --- | --- |
+| Private-CA camera certificate | `HTTPS` |
+| Bosch `DeviceCertificate` | `CBS client` |
+
+The browser may warn about the new HTTPS certificate until the private root CA
+is trusted by the workstation.
+
+## Account for the Bosch chain behavior
+
+The tested firmware served only the leaf certificate on ports `443` and `9554`,
+even when the uploaded file contained the leaf and intermediate. Uploading the
+intermediate separately as a trusted camera certificate did not change the
+served chain.
+
+Confirm the behavior:
+
+```bash
+openssl s_client \
+  -connect 10.0.30.11:9554 \
+  -showcerts </dev/null 2>/dev/null |
+  grep -c '^-----BEGIN CERTIFICATE-----$'
+```
+
+A result of `1` means the client must already have the issuing intermediate.
+Create a portable trust bundle containing the intermediate and root:
+
+```bash
+step certificate bundle \
+  "$HOME/.step/certs/intermediate_ca.crt" \
+  "$HOME/.step/certs/root_ca.crt" \
+  "$HOME/.step/camera/uug-camera-trust-bundle.pem"
+
+chmod 644 "$HOME/.step/camera/uug-camera-trust-bundle.pem"
+```
+
+The trust bundle is public material. The CA private keys and password are not.
+
+## Configure Kerberos Agent
+
+For a process running directly in the same environment:
+
+```dotenv
+AGENT_CAPTURE_IPCAMERA_RTSP="rtsps://<user>:<password>@10.0.30.11:9554/?inst=1"
+AGENT_CAPTURE_IPCAMERA_SUB_RTSP="rtsps://<user>:<password>@10.0.30.11:9554/?inst=2"
+AGENT_CAPTURE_IPCAMERA_RTSPS_INSECURE=false
+AGENT_CAPTURE_IPCAMERA_RTSPS_CA_FILE=/home/agent/data/config/uug-camera-trust-bundle.pem
+```
+
+For a container, mount the public bundle read-only at the exact path visible
+inside the container. The Agent image creates `/home/agent/data/config` and
+includes Debian's `ca-certificates` package:
+
+```bash
+docker run \
+  -v /secure/config/uug-camera-trust-bundle.pem:/home/agent/data/config/uug-camera-trust-bundle.pem:ro \
+  -e AGENT_CAPTURE_IPCAMERA_RTSPS_CA_FILE=/home/agent/data/config/uug-camera-trust-bundle.pem \
+  -e AGENT_CAPTURE_IPCAMERA_RTSPS_INSECURE=false \
+  -e 'AGENT_CAPTURE_IPCAMERA_RTSP=rtsps://<user>:<password>@10.0.30.11:9554/?inst=1' \
+  -e 'AGENT_CAPTURE_IPCAMERA_SUB_RTSP=rtsps://<user>:<password>@10.0.30.11:9554/?inst=2' \
+  kerberos/agent:latest
+```
+
+`AGENT_CAPTURE_IPCAMERA_RTSPS_CA_FILE` starts with the operating system's roots
+and appends the camera bundle only to the gortsplib TLS configuration. Other
+clients, including MoQ, Hub, and Vault, retain the normal public CA chain.
+Restart the Agent after changing trust files.
+
+Do not set `SSL_CERT_FILE` or `SSL_CERT_DIR` in production solely for camera
+trust. They are process-wide and can prevent other clients from validating
+public services. For a deliberate process-wide isolation test, mount an empty
+directory and set `SSL_CERT_DIR` to its path:
+
+```bash
+-v /secure/config/empty-ca-dir:/home/agent/data/config/empty-ca-dir:ro \
+-e SSL_CERT_DIR=/home/agent/data/config/empty-ca-dir
+```
+
+Do not use `SSL_CERT_DIR=`. Go treats an empty value as unset and scans its
+default certificate directories.
+
+Only use that mode when the Agent does not need public roots for other TLS
+connections.
+
+## Validate the live endpoints
+
+### Strict TLS and identity check
+
+Use only the specified bundle, without OpenSSL's default CA locations:
+
+```bash
+openssl s_client \
+  -brief \
+  -connect 10.0.30.11:9554 \
+  -verify_ip 10.0.30.11 \
+  -verify_return_error \
+  -CAfile "$HOME/.step/camera/uug-camera-trust-bundle.pem" \
+  -no-CApath \
+  -no-CAstore \
+  </dev/null
+```
+
+Repeat with port `443`. Both must report `Verification: OK`.
+
+Confirm that identity checking is active by repeating the command with a wrong
+address, such as `-verify_ip 10.0.30.12`. It must fail with an IP address
+mismatch.
+
+### Confirm the live leaf is the generated leaf
+
+```bash
+live_fingerprint=$(
+  openssl s_client -connect 10.0.30.11:9554 -showcerts </dev/null 2>/dev/null |
+    openssl x509 -noout -fingerprint -sha256 |
+    cut -d= -f2
+)
+
+local_fingerprint=$(
+  openssl x509 \
+    -in "$HOME/.step/camera/bosch-rtsps-chain.pem" \
+    -noout -fingerprint -sha256 |
+    cut -d= -f2
+)
+
+test "$live_fingerprint" = "$local_fingerprint"
+```
+
+### Validate the media path
+
+A successful TLS handshake does not prove that RTSP authentication, DESCRIBE,
+SETUP, PLAY, and RTP delivery work. Start a fresh Agent with verified TLS and
+confirm that it connects without an x509 error and receives frames. During the
+verified setup described here, a gortsplib probe completed all RTSP operations
+and received an RTP packet over TCP.
+
+## Why a tampered bundle may still connect
+
+Editing PEM text is not always a useful negative TLS test.
+
+### A certificate can still parse after a byte change
+
+Base64 can remain syntactically valid when one character changes. OpenSSL may
+still list the certificate subject and issuer even though a signature is now
+invalid. Parsing and signature verification are different operations.
+
+### Trust anchors are not validated through a parent
+
+Every certificate loaded into Go's root pool is a trust anchor, including a
+non-self-signed intermediate CA. Verification can terminate at that certificate.
+
+If tampering changes only the intermediate's signature from its parent root,
+but does not change its public key, that intermediate can still validate the
+camera leaf when it is trusted directly. Its now-invalid parent signature is
+not consulted at the trust boundary.
+
+This is equivalent to OpenSSL's partial-chain behavior:
+
+```bash
+openssl s_client \
+  -connect 10.0.30.11:9554 \
+  -verify_ip 10.0.30.11 \
+  -verify_return_error \
+  -partial_chain \
+  -CAfile tampered-bundle.pem \
+  -no-CApath \
+  -no-CAstore \
+  </dev/null
+```
+
+### `SSL_CERT_FILE` does not isolate Go from CA directories
+
+On Unix, Go uses `SSL_CERT_FILE` instead of its default aggregate CA file, but it
+still scans default certificate directories such as `/etc/ssl/certs`. Setting
+`SSL_CERT_FILE` alone therefore does not remove CA certificates installed with
+`update-ca-certificates`. `AGENT_CAPTURE_IPCAMERA_RTSPS_CA_FILE` is appended
+after this system pool is loaded; it does not replace the system roots.
+
+Blank values do not select empty trust sources. Both `SSL_CERT_FILE=` and
+`SSL_CERT_DIR=` are treated as unset, so Go falls back to its default aggregate
+CA file and certificate directories. To test with no trusted certificates on
+Linux, use a non-empty file path that contains no certificates and a non-empty
+directory path that contains no certificates:
+
+```bash
+mkdir -p /tmp/empty-ca-dir
+SSL_CERT_FILE=/dev/null \
+SSL_CERT_DIR=/tmp/empty-ca-dir \
+AGENT_CAPTURE_IPCAMERA_RTSPS_CA_FILE= \
+AGENT_CAPTURE_IPCAMERA_RTSPS_INSECURE=false \
+GOWORK=off \
+go run -tags moq . -action run -port 8080
+```
+
+That fresh process must fail with `x509: certificate signed by unknown
+authority`.
+
+Use exactly one camera trust-distribution approach when possible:
+
+1. Mount a private trust bundle and set
+  `AGENT_CAPTURE_IPCAMERA_RTSPS_CA_FILE`; or
+2. Install the CA certificates into the operating-system trust store.
+
+Using both is valid, but makes isolation tests less obvious.
+
+### Running processes can retain old roots
+
+A long-running Go process may already have loaded and cached the trust pool.
+Always start a new process after changing trust configuration during a negative
+test.
+
+## Perform a meaningful negative test
+
+Do not corrupt only the root or intermediate signature. Instead, give a fresh
+Agent process a completely unrelated CA and hide the default CA directories.
+
+```bash
+mkdir -p /tmp/empty-ca-dir
+
+openssl req \
+  -x509 -newkey rsa:2048 -nodes -days 1 \
+  -subj '/CN=Unrelated Test Root' \
+  -keyout /tmp/unrelated-test-root.key \
+  -out /tmp/unrelated-test-root.crt
+
+SSL_CERT_FILE=/dev/null \
+SSL_CERT_DIR=/tmp/empty-ca-dir \
+AGENT_CAPTURE_IPCAMERA_RTSPS_CA_FILE=/tmp/unrelated-test-root.crt \
+AGENT_CAPTURE_IPCAMERA_RTSPS_INSECURE=false \
+GOWORK=off \
+go run -tags moq . -action run -port 8080
+```
+
+The connection must fail with an unknown-authority or chain-building error.
+Delete the temporary test key and certificate afterward.
+
+To test bundle integrity rather than client distrust, validate the intermediate
+against the root explicitly:
+
+```bash
+openssl verify \
+  -CAfile "$HOME/.step/certs/root_ca.crt" \
+  -no-CApath \
+  -no-CAstore \
+  "$HOME/.step/certs/intermediate_ca.crt"
+```
+
+Store and compare approved SHA-256 fingerprints when detecting unauthorized
+certificate-file changes is a requirement.
+
+Restore an accidentally edited bundle from the protected CA certificates, then
+restart the Agent:
+
+```bash
+step certificate bundle -f \
+  "$HOME/.step/certs/intermediate_ca.crt" \
+  "$HOME/.step/certs/root_ca.crt" \
+  "$HOME/.step/camera/uug-camera-trust-bundle.pem"
+
+openssl verify \
+  -CAfile "$HOME/.step/certs/root_ca.crt" \
+  -no-CApath \
+  -no-CAstore \
+  "$HOME/.step/certs/intermediate_ca.crt"
+```
+
+## Optional system trust installation
+
+On Debian, install both public CA certificates when every process in the system
+should trust this camera PKI:
+
+```bash
+sudo install -m 0644 \
+  "$HOME/.step/certs/root_ca.crt" \
+  /usr/local/share/ca-certificates/uug-camera-ca.crt
+
+sudo install -m 0644 \
+  "$HOME/.step/certs/intermediate_ca.crt" \
+  /usr/local/share/ca-certificates/uug-camera-intermediate-ca.crt
+
+sudo update-ca-certificates
+```
+
+This creates links below `/etc/ssl/certs`. Remove those files and rerun
+`update-ca-certificates` before attempting an isolated trust-bundle test.
+
+## Renewal and recovery
+
+- Renew before the leaf or intermediate expires.
+- Generate a new camera CSR if the firmware cannot renew the existing key.
+- Sign the new CSR with all required SANs.
+- Upload and validate the new certificate before deleting the old one.
+- Preserve an alternate administrative access path while changing HTTPS usage.
+- Back up the CA certificates, encrypted CA keys, and password separately.
+- If the CA private keys are lost, create a new CA and redistribute its trust
+  before replacing camera certificates.
+
+## Production checklist
+
+- [ ] The Agent URL uses `rtsps://`, not `rtsp://` or `srtsp://`.
+- [ ] RTSPS is enabled on the camera and the configured port is reachable.
+- [ ] The certificate SAN exactly matches the Agent URL host.
+- [ ] The leaf public key matches the camera-generated CSR.
+- [ ] The certificate has `serverAuth` extended key usage.
+- [ ] The certificate expires before its issuer.
+- [ ] HTTPS is assigned to the private-CA certificate.
+- [ ] CBS client remains assigned to the Bosch device certificate.
+- [ ] The Agent has the intermediate and root CA certificates it needs.
+- [ ] `AGENT_CAPTURE_IPCAMERA_RTSPS_INSECURE=false`.
+- [ ] The Agent was restarted after trust changes.
+- [ ] A strict TLS check reports `Verification: OK`.
+- [ ] A real Agent connection receives RTP packets.
+- [ ] CA private keys and passwords are backed up outside the devcontainer.

+### Direct S3 recording layout
+
+Direct S3 uploads store recordings as
+`<s3.username>/yyyy/mm/dd/<timestamp>-<deviceKey>.mp4`. The timestamp is the
+recording's Unix timestamp in milliseconds, and the date is its UTC date, not the upload
+date. Timestamp and device key come from the recording's `.metadata` upload
+checkpoint, which stores the timestamp in milliseconds. The uploader also
+preserves checkpoint duration, FPS (when available), and encryption status as S3
+object metadata. The device key must be non-empty and contain no path separators.
+Retried uploads use the same object key, even after midnight. Millisecond
+precision keeps recordings starting within the same second distinct.
+
+This replaces the previous `<s3.username>/<filename>.mp4` layout for new uploads.
+Existing objects are not moved; consumers of direct S3 uploads must support both
+layouts when reading historical recordings. Updated Kerberos Vault deployments
+use the same filename and dated layout under the authenticated account directory
+for both direct Vault uploads and Hub-proxied uploads.
+
+Only historical recordings with missing, empty, or FPS-only queue markers fall
+back to the legacy filename format and configured Agent key. A structured
+checkpoint takes precedence over both the filename and current configured key;
+an invalid or unreadable checkpoint is reported as an upload error, not silently
+replaced with filename-derived values.
+For older structured checkpoints, missing camera name, region, and change count
+are recovered from a validated legacy filename. Populated checkpoint fields
+take precedence, and the checkpoint timestamp and device key remain authoritative.
+
+The shorter filename cannot be decoded by legacy filename-only consumers.
+Integrations must preserve structured recording metadata, including the device
+key (`productid`) and recording timestamp (`event-timestamp`), as well as the full
+object key.
+
+### Local recording layout
+
+New local recordings are stored under
+`data/recordings/yyyy/mm/dd/<timestamp>-<deviceKey>.mp4`, using the recording's UTC
+start date and Unix-millisecond timestamp. For example:
+`data/recordings/2026/01/02/1767355200123-device-key.mp4`.
+The filename no longer embeds the camera name, region, change count, or duration,
+and it does not change when the recording is finalized.
+Those attributes, together with FPS and encryption status, are captured in the
+`.metadata` upload checkpoint and sent as structured HTTP/tus metadata.
+
+Existing flat recordings and dated recordings with older long filenames remain
+supported without a migration. Recording lists, day filters, playback, uploaders,
+and automatic cleanup handle both filename formats and layouts. Upload queue
+checkpoints remain flat in `data/cloud/`. Successful-upload removal also resolves
+both local layouts. Deploy the updated Vault alongside Agent for canonical
+`<account-directory>/yyyy/mm/dd/<timestamp>-<deviceKey>.mp4` storage keys and
+metadata-driven Hub integration events.
+Directory decryption also processes dated subdirectories and writes each output
+to a sibling `decrypted/` directory; those outputs are excluded from recording
+lists and automatic cleanup.

 ## Quickstart - Docker
 
 The easiest way to get your Kerberos Agent up and running is to use our public image on [Docker hub](https://hub.docker.com/r/kerberos/agent). Once you have selected a specific tag, run `docker` command below, which will open the web interface of your Kerberos agent on port `80`, and off you go. For a more configurable and persistent deployment have a look at [Running and automating a Kerberos Agent](#running-and-automating-a-kerberos-agent).
 
-    docker run -p 80:80 --name mycamera -d --restart=always kerberos/agent:latest
+**Forthcoming hardened image** (use this mapping only after upgrading to a
+release containing these changes):
+
+    docker run -p 80:8080 --name mycamera -d --restart=always kerberos/agent:latest
+
+The hardened image listens on **8080 inside the container**, not 80. The mapping
+`-p 80:8080` keeps the browser URL `http://localhost/` unchanged. When upgrading,
+change the container side of existing `80:80` or `8082:80` mappings to
+`80:8080` or `8082:8080`. Kubernetes Services must use `targetPort: 8080`.
+Older published images still use their original port: these examples require a
+release containing the hardening changes; pin its published digest in production.
+For the currently published `v3.14.1`, retain the old mapping:
+
+    docker run -p 80:80 --name mycamera -d --restart=always kerberos/agent:v3.14.1
+
+The image uses a Go 1.26 scratch runtime with only required dynamic/media
+dependencies, numeric non-root UID/GID `999:999`, no file capabilities or
+setuid/setgid programs, and an application healthcheck (no curl-based probe).
+UI assets are immutable; demo mode selects its environment without rewriting them.
+Source builds require the patched Go 1.26.10 toolchain or newer.
+It supports dropping all capabilities and preventing privilege escalation:
+
+```sh
+docker run --cap-drop=ALL --security-opt=no-new-privileges:true \
+  -p 80:8080 --name mycamera -d kerberos/agent:latest
+```
+
+See the [image contract](deployments/docker/README.md#image-contract) for writable
+paths, health checks, supported architectures, signature/evidence requirements,
+and release-policy gaps. Functional remote-shell support remains a **pending
+policy exception**, so this is not a claim of full image-hardening baseline or
+CIS compliance.
+Release promotion is also blocked by remaining native-library scan findings;
+this PR is not release-qualified. The existing recording-signing key and trust
+behavior are retained under the user's narrowly scoped exception through
+December 5, 2026 (23:59:59 UTC), recorded for review in this PR. The finding
+remains visible in scan reports; other keys and findings are not exempted.
 
 If you want to connect to a USB or Raspberry Pi camera, [you'll need to run our side car container](https://github.com/kerberos-io/camera-to-rtsp) which proxies the camera to an RTSP stream. In that case you'll want to configure the Kerberos Agent container to run in the host network, so it can connect directly to the RTSP sidecar.
 
     docker run --network=host --name mycamera -d --restart=always kerberos/agent:latest
 
+With host networking, no port mapping applies: the hardened Agent is reachable
+on host port `8080` by default.

 You attach a volume to your container by leveraging the `-v` option. To mount your own configuration file and recordings folder, run the following commands:
 
-    docker run -p 80:80 --name mycamera \
+    docker run -p 80:8080 --name mycamera \
     -v $(pwd)/agent/config:/home/agent/data/config \
     -v $(pwd)/agent/recordings:/home/agent/data/recordings \
     -d --restart=always kerberos/agent:latest
 
 More examples for each deployment and automation tool [can be found in the deployment section](https://github.com/kerberos-io/agent/tree/master/deployments). Be sure to verify the permissions of the directory/volume you are attaching. More information in [this issue](https://github.com/kerberos-io/agent/issues/80).
 
-    chmod -R 755 kerberos-agent/
-    chown 100:101 kerberos-agent/ -R
+The current image runs as UID `999`, GID `999`. Give that user ownership of
+the mounted directories (older image tags may use different IDs):
+
+    sudo chown -R 999:999 agent/config agent/recordings
+

+for reduced-capability deployment and migration guidance.
 
 ## Configure with environment variables
 
 Next to attaching the configuration file, it is also possible to override the configuration with environment variables. This makes deploying with `docker compose` or `kubernetes` much easier and more scalable. Using this approach, we simplify automation through `ansible` and `terraform`.
 
-    docker run -p 80:80 --name mycamera \
+    docker run -p 80:8080 --name mycamera \
     -e AGENT_NAME=mycamera \
     -e AGENT_TIMEZONE=Europe/Brussels \
     -e AGENT_CAPTURE_IPCAMERA_RTSP=rtsp://fake.kerberos.io/stream \
     -e AGENT_CAPTURE_CONTINUOUS=true \
     -d --restart=always kerberos/agent:latest
 
+Set `AGENT_PORT` to change the Agent's internal HTTP port. The environment
+variable takes precedence over `-port`. When using Docker, publish the same
+container port:
+
+```bash
+docker run -p 8082:8082 \
+  -e AGENT_PORT=8082 \
+  --name mycamera \
+  -d --restart=always kerberos/agent:latest
+```
+
+### Health checks and API responses
+
+`GET /health` is an unauthenticated liveness and diagnostics endpoint for
+container orchestrators and external monitors. `healthy` means that the Agent
+HTTP process can serve requests. Camera streams and Hub connectivity are
+reported independently in the response, so an external camera or Hub outage
+does not make Docker restart an otherwise functioning Agent process. Successful
+probes return `200 OK` and are logged at debug level to avoid periodic health
+checks filling production logs.
+
+```bash
+curl http://localhost:8082/health
+```
+
+```json
+{
+  "httpStatusCode": 200,
+  "applicationStatusCode": "get_success",
+  "entityStatusCode": "healthy",
+  "message": "Healthy",

+      }
+    }
+  }
+}
+```
+
+Stream `packagesProcessed` counts complete encoded video access units processed
+since the Agent process started; it does not count individual fragmented RTP
+packets. `fps` is the latest PTS-derived frame-rate estimate. Resolution is the
+most recently observed encoded width and height. `lastPacketAt`, Hub heartbeat
+timestamps, and response metadata timestamps are Unix seconds; `0` means that
+no value has been observed yet. A stream can be configured but temporarily
+disconnected.
+
+Hub `configured` means heartbeat delivery is enabled and has the required URI
+and key. Hub `connected` means the most recent heartbeat succeeded and the last
+success is no more than three minutes old. A failed heartbeat marks it
+disconnected immediately while retaining the last-success timestamp for
+diagnosis.
+
+New JSON endpoints should use this Hub-compatible response envelope rather than
+adding unrelated top-level response shapes. HTTP status describes the transport
+result, `applicationStatusCode` describes the operation, `entityStatusCode` and
+`message` describe the domain outcome, `metadata` carries request/application
+context, and endpoint-specific content belongs in a typed `data` object. Client
+responses must contain safe messages only; detailed internal errors belong in
+structured logs. Existing endpoints retain their legacy response shapes until
+they are migrated deliberately.
+
+### Secure camera streams (RTSPS)
+
+The Agent accepts `rtsps://` camera URLs. Do not use `srtsp://`; RTSPS is RTSP over TLS. For a Bosch FLEXIDOME micro 3100i, enable **Secure RTSP** under **Network > Network Services** and use port `9554`:
+
+```bash
+AGENT_CAPTURE_IPCAMERA_RTSP='rtsps://username:password@camera.example:9554/?inst=1'
+AGENT_CAPTURE_IPCAMERA_SUB_RTSP='rtsps://username:password@camera.example:9554/?inst=2'
+```
+
+Certificate verification is enabled by default. The URL hostname or IP address must match the camera certificate SAN. On this Bosch firmware, RTSPS presents the certificate assigned to **HTTPS**; there is no separate SRTSP certificate usage. Leave **CBS client** assigned to the Bosch device certificate.
+
+For a private CA, mount a PEM trust bundle containing every CA certificate needed to build the camera certificate chain and set `AGENT_CAPTURE_IPCAMERA_RTSPS_CA_FILE` to its path inside the Agent. The bundle is appended to the system roots for camera RTSPS connections only. This Bosch firmware presents only its leaf certificate, so include both the issuing intermediate and root certificates in the bundle. As a temporary fallback, `AGENT_CAPTURE_IPCAMERA_RTSPS_INSECURE=true` disables certificate verification for camera streams only.
+
+See [RTSPS and TLS certificates](README-RTSPS-TLS.md) for the complete Bosch UI, private-CA, deployment, validation, and troubleshooting procedure.

+Remote console access is disabled unless `AGENT_REMOTE_ACCESS_ENABLED=true`.
+The Agent also rejects remote session messages unless Hub encryption or
+end-to-end MQTT encryption is configured and used. A remote shell runs inside
+the Agent process environment as the Agent operating-system user; it is not an
+SSH server and does not expose a new network port. Keep the feature disabled on
+deployments where Hub owners should not have operating-system access.
+
+### Resumable upload chunk size
+
+Hub and Vault resumable uploads use `AGENT_TUS_CHUNK_SIZE_BYTES` as the maximum
+body size of each tus `PATCH` request. The value is a number of bytes, not a
+number of chunks. If the variable is unset or invalid, the Agent uses 8 MiB:
+
+```dotenv
+# 8 MiB (default)
+AGENT_TUS_CHUNK_SIZE_BYTES=8388608
+
+# 4 MiB: more frequent checkpoints on unstable connections
+AGENT_TUS_CHUNK_SIZE_BYTES=4194304
+
+# Disable chunking and send all remaining bytes in one PATCH
+AGENT_TUS_CHUNK_SIZE_BYTES=0
+```
+
+Smaller chunks provide more frequent resumable checkpoints but create more HTTP
+requests. Larger chunks reduce request overhead but require more data to be
+retransmitted when a request fails.
+
+An HTTP 500 during resumable creation is a server/provider failure, not proof
+that the recording filename is invalid. Creation errors include up to 4 KiB of
+the server response, and the final retry error retains the latest failure cause.
+Created upload sessions remain usable if only the optional creation response
+body is interrupted; the successful response's `Location` is retained.
+Check the corresponding Hub/Vault logs and storage-provider configuration.
+As a temporary diagnostic workaround, set `AGENT_DISABLE_RESUMABLE_UPLOAD=true`
+and restart Agent to use ordinary uploads. This does not change the recording
+filename or remove its structured metadata, but interrupted uploads restart
+from the beginning. Remove the override after fixing the provider issue.
+
+### Custom metadata headers for Kerberos Vault
+
+Use `AGENT_KERBEROSVAULT_CUSTOM_HEADERS` to attach your own metadata (for
+example a site, line, or equipment identifier) to every recording uploaded to
+Kerberos Vault. The value is a JSON object whose keys are header names and whose
+values are strings. The Agent sends these as HTTP headers on every upload, and
+Vault adds them to the `metadata` object of its integration messages (Kafka,
+MQTT, SQS, RabbitMQ, etc.):
+
+```json
+{
+  "timestamp": "2026-09-24T15:06:45Z",
+  "key": "agent1/1790262405_3-425_agent1_0-0-0-0_-1_10000.mp4",
+  "device": "agent1",
+  "metadata": {
+    "site_id": "site-1",
+    "line_id": "line-2",
+    "equipment_id": "equipment-3"
+  }
+}
+```
+
+The value must be valid JSON on a single line, so wrap it in single quotes in a
+shell:
+
+```bash
+docker run -p 80:8080 --name mycamera \
+  -e AGENT_CLOUD=kstorage \
+  -e AGENT_KERBEROSVAULT_URI=https://vault.domain.com/api \
+  -e AGENT_KERBEROSVAULT_ACCESS_KEY=xxx \
+  -e AGENT_KERBEROSVAULT_SECRET_KEY=xxx \
+  -e AGENT_KERBEROSVAULT_DIRECTORY=agent1 \
+  -e AGENT_KERBEROSVAULT_CUSTOM_HEADERS='{"site_id":"site-1","line_id":"line-2","equipment_id":"equipment-3"}' \
+  -d --restart=always kerberos/agent:latest
+```
+
+In `docker compose` or an `.env` file:
+
+```yaml
+services:
+  agent:
+    image: kerberos/agent:latest
+    environment:
+      AGENT_CLOUD: kstorage
+      AGENT_KERBEROSVAULT_CUSTOM_HEADERS: '{"site_id":"site-1","line_id":"line-2","equipment_id":"equipment-3"}'
+```
+
+```dotenv
+AGENT_KERBEROSVAULT_CUSTOM_HEADERS={"site_id":"site-1","line_id":"line-2","equipment_id":"equipment-3"}
+```
+
+In Kubernetes, quote the value so YAML keeps it as a string:
+
+```yaml
+env:
+  - name: AGENT_KERBEROSVAULT_CUSTOM_HEADERS
+    value: '{"site_id":"site-1","line_id":"line-2","equipment_id":"equipment-3"}'
+```
+
+Use `AGENT_KERBEROSVAULT_SECONDARY_CUSTOM_HEADERS` for the secondary Vault. In
+ConfigMap deployments you can set shared defaults with the `GLOBAL_` prefix
+(for example `GLOBAL_AGENT_KERBEROSVAULT_CUSTOM_HEADERS`) and override them per
+agent with `AGENT_KERBEROSVAULT_CUSTOM_HEADERS`. You can also set the same JSON
+under **Settings → Persistence → Custom upload headers** in the Agent UI, which
+stores it as `kstorage.custom_headers` in `config.json`.
+
+The rules for this value are:
+
+- It must be a JSON object with string values. Numbers, `null`, arrays, and
+  nested objects are rejected.
+- It can contain up to 32 headers, with names up to 128 characters and values
+  up to 4096 bytes.
+- Header names must be valid HTTP tokens (letters, digits, and ``!#$%&'*+-.^_`|~``).
+  Keys are matched case-insensitively, so `site_id` and `SITE_ID` cannot both
+  be used.
+- Reserved names are rejected: anything starting with `X-Kerberos-`,
+  `Authorization`, `Cookie`, `Host`, `Content-Type`, `Content-Length`,
+  `Trace-Id`, tus protocol headers (`Tus-Resumable`, `Upload-*`), and
+  hop-by-hop headers.
+- Values cannot contain line breaks, tabs, or other control characters.
+
+If the value is invalid, the Agent logs an error and does not upload to that
+Vault until the configuration is fixed. The recording stays queued, so it will
+upload once the value is corrected. Header names reach Vault unchanged, but
+proxies may normalise their casing. If Vault redirects an upload to another
+host, the Agent removes the custom headers and Vault credentials before
+following the redirect.

 ## Building for Docker
 
-Inside the root of this `agent` repository, you will find a `Dockerfile`. This file contains the instructions for building and shipping a **Kerberos Agent**. Important to note is that you start from a prebuilt base image, `kerberos/base:xxx`.
-This base image already contains a couple of tools, such as Golang, FFmpeg and OpenCV. We do this for faster compilation times.
+Inside the root of this `agent` repository, you will find a `Dockerfile`. This file contains the instructions for building and shipping a **Kerberos Agent**. It uses Debian Trixie to support the native dependencies used by the Agent, including Media over QUIC.
 
 By running the `docker build` command, you will create the Kerberos Agent Docker image. After building you can simply run the image as a Docker container.
 
     docker build -t kerberos/agent .
 
+### Media over QUIC
+
+The standard AMD64 and ARM64 images include the optional MoQ publisher. Its Rust
+FFI archive requires CGO and glibc 2.38 or newer, which is why the standard image
+uses Debian Trixie. The publisher is disabled unless explicitly enabled at runtime:
+
+    docker run --rm -p 80:8080 \
+      -e AGENT_LIVE_MOQ_ENABLED=true \
+      -e AGENT_LIVE_MOQ_URL=https://relay.uug.ai/anon \
+      kerberos/agent
+
+`AGENT_LIVE_MOQ_BROADCAST_PREFIX` defaults to `devices`. MoQ viewers subscribe to
+a relay and never negotiate with the Agent, so every quality tier is published as
+its own broadcast and switching quality is simply a resubscribe:
+
+| Tier   | Broadcast                             | Source                                     |
+| ------ | ------------------------------------- | ------------------------------------------ |
+| `high` | `devices/<agent-key>/live.hang`       | highest-resolution camera stream           |
+| `low`  | `devices/<agent-key>/live-low.hang`   | sub stream (main stream when none is set)  |
+
+Each tier uploads every frame while it has subscribers. While idle, it continues
+to upload fresh keyframes only. This keeps the relay's latest cached GOP current,
+so a new viewer does not initially render the final frame from the previous
+viewer session, while avoiding the bandwidth cost of continuously sending every
+delta frame. `AGENT_LIVE_MOQ_QUALITY` accepts `high` or `low` to pin the Agent to
+a single tier; viewers requesting the other tier then find no broadcast. Any
+other value (including the default) publishes both. The initial implementation
+publishes H.264 video only.
+
+Two bounded duration settings tune recovery for unusual network conditions:
+
+| Variable | Default | Allowed range |
+| -------- | ------- | ------------- |
+| `AGENT_LIVE_MOQ_MAX_PACKET_AGE` | `1.5s` | `250ms` to `30s` |
+| `AGENT_LIVE_MOQ_WRITE_TIMEOUT` | `5s` | `1s` to `1m` |
+
+Values use Go duration syntax and are clamped to the documented range. The
+dashboard API's `recovery` object reports per-tier reconnects, last successful
+frame/write timing, native write timeouts, watchdog restarts/cooldown, dropped
+run-channel events, and run-worker shutdown timeouts.
+
+The `/anon` relay route is intended for interoperability testing. Production
+deployments must set `AGENT_LIVE_MOQ_URL` to a short-lived, device-scoped
+publisher URL issued by Hub API.
+
+To verify the native SDK in a development container, rebuild the Agent or shared
+monorepo devcontainer so it uses the Trixie base, then run the VS Code task
+`agent: moq verify`. The same check is available from a terminal:
+
+    cd machinery
+    bash ./verify-moq-devcontainer.sh
+
+The check requires glibc 2.38 or newer, runs the tagged package and in-process
+native QUIC lifecycle tests, links the complete Agent with `-tags moq`, and
+executes the resulting binary's version
+command. Both devcontainers also run this check during their post-create setup.
+
 ## What is new?
 
 This repository contains the next generation of Kerberos.io, **Kerberos Agent (v3)**, and is the successor of the machinery and web repositories. A switch in technologies and architecture has been made. This version is still under active development and can be followed on the [develop branch](https://github.com/kerberos-io/agent/tree/develop) and [project overview](https://github.com/kerberos-io/agent/projects/1).

 Kubernetes is great, but you might love OpenShift even more. In this directory you'll find some resources to deploy your Kerberos Agent in an OpenShift cluster using Ansible playbook. We'll review the different tasks of the Ansible playbook step by step; find the complete `playbook.yaml` here.
 
+The playbook's port mapping targets the forthcoming hardened image:
+`containerPort: 8080` and `targetPort: 8080`, with external Service port `80`
+unchanged. Previously published images, including `v3.14.1`, still need the old
+container port 80. Upgrade the image and mapping together and pin its published
+digest. See the [image contract](../docker/README.md#image-contract) for numeric
+UID/GID `999:999`, writable data/cache paths and release blockers. OpenShift SCCs
+may override the UID; provision matching volume permissions and verify your
+cluster's policy rather than granting privileged access. This legacy playbook's
+credential-debugging/certificate-validation settings also require production
+review; the image/port update does not certify the cluster deployment.

 ## Variabeles
 
 We'll have a few `variables` in our `playbook.yml` that will help us to setup secure connection with the OpenShift cluster. We need the `cluster_url` and the `username` and `password` of the OpenShift cluster. If you don't know where to find this, you can find this in the OpenShift web ui.

+compliance. Use a release's actual published multi-platform digest, for example
+`kerberos/agent:<version>@sha256:<digest>`, rather than treating mutable `latest`
+as immutable. No new release digest or signature is asserted by this PR.
+
+| Property | Contract |
+|---|---|
+| Identity | Fixed numeric `USER 999:999`, account `agent`, primary group `kerberosio`; not root and no privilege-changing startup. |
+| Startup | Working directory `/home/agent`; exec-form default command `./main -action run`. Standalone binary CLI defaults remain unchanged. |
+| Inbound HTTP | TCP `8080`, configurable with `AGENT_PORT` (overrides `-port`). Use an unprivileged port. Map host `80:8080`, or Service port `80` to `targetPort: 8080`. Terminate inbound TLS at a trusted proxy; the default listener is HTTP. |
+| Privileges | No bundled setuid/setgid programs or file capabilities. Run with all capabilities dropped and `no-new-privileges`; no `NET_BIND_SERVICE` is required. |
+| Writable application paths | Only `/home/agent/data/` (configuration, recordings, snapshots, cloud, tus checkpoints, capture tests and logs). Binary, UI assets and application home remain root-owned/read-only to UID 999. Demo mode serves its environment without rewriting UI assets. |
+| Temporary state | `/tmp`, `/var/tmp`; user font/media caches under `XDG_CACHE_HOME=/tmp/agent-cache`, owned by `999:999` with mode `0700`. Recreate that directory with these permissions when mounting a fresh tmpfs over `/tmp`. |
+| Health | Exec `/home/agent/main -action healthcheck`; five-second bounded localhost `/health` probe on the resolved port, no proxy/redirects, validates the Agent JSON envelope, exits nonzero on failure. Docker timeout is ten seconds. |
+| Readiness and metrics | `/health` is HTTP liveness, not proof of camera, MQTT or Hub readiness. Camera/Hub details are diagnostic. This image does not add a Prometheus metrics listener. |
+| Certificates/time | Debian CA bundle, OpenSSL configuration and timezone data retained. Mount a prepared CA bundle read-only and use `SSL_CERT_FILE` where appropriate for Go clients; native FFmpeg/OpenSSL clients may require their own CA configuration. Do not disable TLS verification as a substitute. |
+| Secrets | Inject application credentials/keys at runtime using the orchestrator's existing environment/configuration mechanisms. Change default credentials before exposing HTTP. Never build production config, `.env`, private keys or registry credentials into an image. No new generic `*_FILE` interface is provided. |
+| Outbound traffic | Configured RTSP/RTSPS/ONVIF camera endpoints, MQTT, Hub/Vault/storage HTTPS endpoints, DNS and optional telemetry; WebRTC may require configured STUN/TURN and negotiated UDP/TCP connectivity. Apply an allowlist suited to the actual enabled integrations. |
+| Architecture | Native AMD64 and ARM64 build/runtime checks; ARMv7 remains a legacy build target needing its own evidence. ARMv6 is blocked by the default builder manifest; see below. |
+
+### Container permissions and hardening
+
+The final image uses `FROM scratch` with an explicitly assembled Debian/glibc
+runtime rather than the whole Debian filesystem. FFmpeg and its required native
+libraries/plugins remain for camera/media functionality, including AAC-to-PCMU.
+Apt/dpkg executables, account/capability-management tools, curl, and bundled
+setuid/setgid permissions are absent. An application subcommand, not shell/curl,
+implements the healthcheck.
+
+```sh
+docker run --cap-drop=ALL --security-opt=no-new-privileges:true \
+  -p 80:8080 --name mycamera -d kerberos/agent:latest
+```
+
+Do not use `--privileged` for ordinary IP cameras. Local cameras still use the
+separate RTSP sidecar; any device access belongs to that sidecar. Host networking
+remains supported, but without a mapping the Agent is reachable on host port
+`8080`, not 80.
+
+The numeric `USER 999:999` does **not** automatically inherit supplementary video
+membership from `/etc/group`. If a deployment deliberately passes a video device
+to Agent, explicitly add the device's host GID: `--group-add 44` for GID 44,
+Compose `group_add: ["44"]`, or Kubernetes `supplementalGroups: [44]`. The runtime
+retains the `video` group record. Match the actual device permissions; this does
+not grant arbitrary device access or replace the separate local-camera sidecar.
+
+**Pending policy exception:** functional remote terminal sessions require
+`/bin/sh`, PTY devices, terminal data and basic GNU utilities. These remain for
+that feature, not healthchecks or debugging convenience. The user chose to
+preserve the feature, but no policy approver, exception owner or expiry has been
+provided. This is not an approved waiver or full baseline/CIS compliance.
+Baseline-qualified release promotion must remain blocked until the exception is
+formally resolved; do not silently remove the feature or manufacture approval.
+
+Bind mounts must be writable by the image's UID/GID; the container does not
+change host ownership at startup. Before migrating an older volume, check the
+user of the exact old and new image with `docker run --rm --entrypoint id IMAGE`
+and adjust only the mounted directories as necessary. For example:
+
+```sh
+sudo chown -R 999:999 agent/config agent/recordings
+```
+
+A read-only root filesystem is not enabled by default: `data/` needs initialized
+writable storage (and FFmpeg or shell sessions may need `/tmp` and `/var/tmp`).
+Empty bind mounts hide packaged configuration/media files; initialize
+them before use. Docker named volumes populate packaged contents on first use.
+Customers enabling read-only root must supply those writable mounts and cache
+ownership, keep the runtime's device/PTY mounts, and validate their enabled media
+and remote-access features. Apply CPU/memory/PID limits, seccomp/AppArmor and
+network policies appropriate to the deployment.
+
+### Building and checking the image
+
+Build from a clean checkout: the default configuration files under
+`machinery/data/config/` are included in the image, so do not replace them with
+production credentials before building. `.dockerignore` excludes local `.env`
+files, credential directories/configuration, test/profiling outputs, recordings,
+upload checkpoints, dependency directories, and unrelated
+repository files from the build context. The builder uses Go `1.26.10` with
+`GOTOOLCHAIN=local`, checksum database verification, and `go mod verify`. Builds
+use `-mod=readonly` to reject implicit module changes, `-trimpath` to omit local
+source paths, and `-buildvcs=false` to omit checkout metadata. CGO remains enabled
+for the native camera/media dependencies.
+
+Source builds require at least Go 1.26.10, matching the pinned security patch floor.
+The Go, Node, and Debian bases are pinned to verified multi-platform manifest
+digests, including AMD64 and ARM64 (and ARMv7 where previously supported).
+The pinned Debian image is used only to assemble the scratch runtime with
+glibc-compatible FFmpeg, CGO, and MoQ dependencies. Its native package dependency
+metadata selects the architecture's dynamic loader, shared libraries, media
+plugins/drivers, and associated data files. This is intentionally broader than
+an `ldd`-only copy, which misses dynamically loaded plugins. Certificates,
+OpenSSL configuration, time zones, font/MIME/pixbuf caches, account records, and
+standard writable `/tmp` and device mount points are retained. The runtime
+uses `XDG_CACHE_HOME=/tmp/agent-cache` for disposable user caches without making
+the application home writable. It contains package provenance in
+`/var/lib/dpkg/status` and license notices, but
+not the package manager. Update it by rebuilding and replacing the image rather
+than installing packages in a running container.
+
+```sh
+docker build --pull -t kerberos/agent:local .
+sh deployments/docker/test-image.sh kerberos/agent:local
+```
+
+The smoke check uses temporary containers and a Docker volume, cleans them up,
+and checks permissions, FFmpeg audio transcoding, H264/sample-video decoding,
+H265 encoding/decoding, font rendering, shell/PTY devices, volume
+initialization/writes, default and custom HTTP ports, health probes, and
+demo-mode startup with a read-only root and immutable UI assets. It enforces
+privileged low ports while running on 8080 with no capabilities and
+`no-new-privileges`, and also checks an overridden port `8082`. PR builds
+run it on native AMD64 and ARM64 runners. It does not replace testing against a
+real camera, hardware codecs/devices, an MQTT-mediated remote shell session, or
+all supported ARM variants. Review and refresh the
+base-image digests regularly for security updates; `--pull` alone does not update
+a pinned digest. `GO_IMAGE` and `RUNTIME_IMAGE` remain overrideable build arguments
+for compatible alternatives. The package repositories are not snapshot-pinned,
+so base digest pins do not make the entire build bit-for-bit reproducible.
+
+Architecture selections are unchanged by this hardening.
+The pinned `golang:1.26.10-trixie` manifest, like the previous Go 1.25 trixie base,
+has no `linux/arm/v6` variant, so the existing ARMv6 nightly target cannot be
+validated with the default base.
+ARMv6 needs a separately reviewed compatible builder/runtime combination; do
+not assume an ARMv7 image runs on ARMv6 hardware.
+
+### Release evidence, vulnerabilities and lifecycle
+
+The hardened release path must build/test the supported release architectures,
+block HIGH/CRITICAL vulnerability/secret/misconfiguration findings, retain scan
+reports and an SBOM, publish build provenance, and sign the **final
+multi-platform index digest**, not just one child manifest. A pending policy
+exception is not an approved scan exception. There are no approved
+vulnerability exceptions in this change; findings require remediation or a
+reviewed owner/expiry/approval record. Scanner/database failures must fail
+closed. Workflow definitions are not evidence that registry publication,
+signing, or scans have already succeeded.
+
+Source scans cover UI production **and build/development** dependencies and retain
+their application inventory/SBOM, because compiled browser assets hide lockfile
+metadata from final-rootfs scanners. Final-image evidence separately covers native
+packages and the Go binary. Current native-library findings remain release
+blockers. The existing embedded recording-signing key and trust behavior are
+retained under the user's time-limited source-secret exception, recorded for
+review in this PR in
+[image-scan-exceptions.json](../../.github/scripts/image-scan-exceptions.json).
+Owner and approver: `@cedricve`; expiry: **December 5, 2026, 23:59:59 UTC**.
+Anyone possessing this shared private key can forge signatures under its
+identity; the exception accepts that risk temporarily, it does not fix it.
+
+The exception matches only that source file's SHA-256, exact scanner rule,
+category, HIGH severity and line location, and requires exactly one match.
+Changes, missing/incomplete approval, expiry or duplicate findings fail closed.
+It cannot exempt an image finding, another secret, a vulnerability or a
+misconfiguration. The policy is loaded from the executing workflow's checkout,
+not the source directory being scanned. Retained `scan.json` still contains the
+redacted HIGH finding; `exception-policy.json`, `exception-decisions.json` and
+`policy.json` record the approval/application, without key material. Review the
+record in PR #350 before merging; repository owners must enforce required reviews.
+This exception does not approve the separate pending remote-terminal policy.
+
+The build jobs run compilation and production-image smoke tests before the
+security gates. A job that fails at **Source/UI dependency and final image gates
+with SPDX SBOMs** is not a compiler or startup failure; inspect its retained
+reports rather than disabling the gate. Patched Go dependencies are checked
+with `govulncheck` as well as the image/source scanner. The pinned
+`golang.org/x/crypto` revision is the official reviewed OpenPGP module split
+for [GO-2026-5932](https://pkg.go.dev/vuln/GO-2026-5932); Agent does not import the
+retired OpenPGP packages.
+
+Debian 13 stable, security and backports currently provide no patched FFmpeg
+7.1.x or libxml2 packages for the blocking findings on either AMD64 or ARM64.
+For example, Debian defers [CVE-2026-58049](https://security-tracker.debian.org/tracker/CVE-2026-58049)
+until an upstream 7.1.x fix; a fix exists in FFmpeg 9. A Wolfi FFmpeg 7 prototype
+had no vendor-scanner findings but still used the same affected upstream
+7.1.5 code and lacked the existing hardware accelerators. It was **not**
+adopted to obtain a misleading clean scan. A newer media stack needs matched
+CGO headers/libraries and validation of codecs, hardware acceleration and
+supported architectures, not an unreviewed mix of testing-distribution packages.
+The user has chosen to keep the default recording-signing key; no trust
+migration or startup change is implemented. Its source-secret finding becomes
+release-blocking again if the scoped exception expires or no longer matches.
+Any future removal would require a separately
+authorized migration: per-installation keys need verifier/public-key provisioning,
+while requiring an injected key changes startup for existing keyless installations.
+
+Before deploying, obtain the release's digest, source revision, supported
+platforms, per-platform SBOM/scan reports, provenance, signature certificate
+identity and policy approvals from its retained release evidence. Verify the
+signature against the **exact trusted workflow identity** and GitHub OIDC issuer,
+not an unrestricted identity regexp:
+
+Workflow artifacts `image-source-evidence` and `image-final-evidence` retain
+sanitized reports, source/application and per-platform SBOMs, provenance, base
+digests and the source revision for 90 days. Successful releases also attach
+`image-security-evidence.tar.gz`. After successful signing,
+`signing-identity.txt` records the exact
+`https://github.com/kerberos-io/agent/.github/workflows/image-release.yml@...`
+identity; the suffix is the executing workflow ref, not necessarily the source
+ref. Require the expected trusted ref, not merely any identity found in an
+artifact. Secret matches/source excerpts are redacted; findings are not waived.
+
+```sh
+# Set these from the trusted release's real evidence, not from this example.
+cosign verify --certificate-identity="$COSIGN_IDENTITY" \
+  --certificate-oidc-issuer=https://token.actions.githubusercontent.com \
+  "$AGENT_IMAGE"
+```
+
+`AGENT_IMAGE` must contain the immutable registry digest. Reject missing,
+mismatched, expired or unapproved evidence; neither a successful local build nor
+`FROM scratch` certifies the image is vulnerability-free. Registry credentials,
+OIDC permissions and repository release protections must be configured by the
+repository owner; this PR does not invent them or certify those external controls.
+
+Review pinned digests and native/package/module findings for every release and
+regularly between releases. Debian 13 has
+[full support until August 9, 2028 and LTS until June 30, 2030](https://www.debian.org/releases/trixie/),
+with reduced LTS architecture/package coverage. The Go 1.26 line is supported
+[until two newer major Go releases exist](https://go.dev/doc/devel/release#policy);
+update its patch pin and replace it before that boundary. The build-only Node 22
+line has [scheduled EOL April 30, 2027](https://github.com/nodejs/Release/blob/main/schedule.json).
+The pinned UI builder is Node `22.23.4` on Alpine `3.24.3`;
+[Alpine 3.24 main support ends June 1, 2028](https://alpinelinux.org/releases/),
+while community support ends at the next stable release. Track both when
+refreshing that build-only base. Rebuilding does not refresh immutable
+base pins automatically, and APT repositories are not snapshot-pinned. Retain the
+actual installed-package/SBOM evidence per architecture and release.

@@ -6,6 +6,27 @@ Kubernetes can help you to build a scalable, flexible and resilient deployment.
 
 We've provided an example deployment `deployment-agent.yml` in this directory, which show case you have to create a deployment (and under the hood a pod), to run a Kerberos Agent workload.
 
+These manifests target the forthcoming hardened image: **containerPort and
+Service targetPort are 8080**, while external Service/Ingress port 80 stays
+unchanged. Pin a published hardened release digest before production use.
+Previously published port-80 images (including `v3.14.1`) require the old
+container/target ports; upgrade the image and mapping together. Host-network
+deployments use host port 8080 without Service port translation.
+
+The examples use UID/GID `999:999`, `fsGroup: 999`, a read-only root filesystem,
+no privilege escalation, all capabilities dropped and runtime-default seccomp.
+A non-root init container copies missing packaged data to the writable volume
+without overwriting existing files and initializes the user cache. Temporary
+storage is ephemeral. The PVC example preserves the existing `config/`,
+`recordings/`, `snapshots/` and `cloud/` directories under the same PVC root,
+mounting that root at `/home/agent/data` to cover all writable data paths.
+Ensure the storage driver honors fsGroup or pre-provision UID/GID permissions.
+If deliberately passing video devices, add their actual GID with
+`supplementalGroups`; ordinary IP cameras do not need that group or devices.
+See the [image contract](../docker/README.md#image-contract), including the pending
+remote-terminal policy exception and release blockers. These examples do not
+assert a running cluster or security-policy approval.
