CLI and setup

Binding design for pmail, the command-line client: configuration, output and exit codes, setup, setup ses, deploy, upgrade, doctor, destroy, secret and signing-key rotation, dead-letter handling and the client-side behaviour of the mail and admin commands. It implements FR-CLI-1, FR-OPS-1 to FR-OPS-3, FR-CON-7 and FR-BILL-12, build plan milestone M16, the CLI half of M17 (dlq), the deploy --version acceptance of M19, the CLI parts of FR-DOM-7 to FR-DOM-12 (M23: domains add --method, domains update, domains probe, addresses test-forwarding, setup ses), of FR-CON-8 (M24: waitlist invite) and of FR-IDN-6 to FR-IDN-8 (M25: identity-keys, assertions, http-sign, keys rotate web_bot_auth, Agent signing keys), and the edge-case rows H5, J8, J9 and N30 in the edge-case register.

Every command, flag and example is listed in the CLI reference; this page decides how they behave.

main.rs builds a #[tokio::main(flavor = "current_thread")] runtime. Commands are async fn run(ctx: &Ctx, args: …) -> Result<Output, CliError>; main renders the Output or the error and maps the error to an exit code (§3.4). No command calls std::process::exit itself.

pub struct Ctx {
    pub profile: ResolvedProfile,      // url, key (may be absent for setup/deploy/doctor)
    pub mode: OutputMode,              // Human | Json | Quiet

}

2. Configuration and credentials

2.1 The config file

The file is ~/.config/pylota-mail/config.toml (Configuration › CLI configuration). $XDG_CONFIG_HOME/pylota-mail/config.toml is used when XDG_CONFIG_HOME is set; on Windows the file is %APPDATA%\pylota-mail\config.toml.

pub struct ConfigFile {
    pub default_profile: Option<String>,
    pub profiles: BTreeMap<String, Profile>,           // name: ^[a-z0-9][a-z0-9_-]{0,31}$
}
pub struct Profile {
    pub url: Option<String>,                           // https://mail.example.com (no path)
    pub key: Option<String>,                           // pmk_live_… / pmk_test_…
    pub key_env: Option<String>,                       // name of an environment variable
    pub key_command: Option<String>,                   // run through the shell; stdout is the key
    pub identity: Option<String>,                      // default --identity for mail commands
    pub tenant: Option<String>,                        // default --tenant for platform keys
    pub account_id: Option<String>,                    // Cloudflare account ID; written by setup
}

• Unknown keys are an error (deny_unknown_fields), so a typo never silently drops a setting.
• At most one of key, key_env and key_command may be set in a profile (exit 3 otherwise).
• Permissions (Unix). The file and its directory are created with modes 0600 and 0700. Before reading, pmail checks st_mode & 0o077 == 0 and that the owner is the current user; otherwise it refuses with exit 3 and the fix chmod 600 <path>. Writes go to a temporary file in the same directory (mode 0600), then rename, so a crash never leaves a half-written file. On Windows the file is created in the user’s profile directory, which only the user can read by default; no mode check is made.
• The Cloudflare API token is never stored in this file. pmail refuses to write a key named like CLOUDFLARE_* into it. The account ID is not a secret: setup stores it in the profile as account_id (§2.5).

2.2 Precedence

Highest first, per setting:

• A missing profile named by --profile or PYLOTA_MAIL_PROFILE is exit 3. A missing default profile is not an error; the URL and key must then come from flags or the environment.
• Which profile setup and login write. setup and login store a key, so they write the profile named by --profile, default default; PYLOTA_MAIL_PROFILE and default_profile do not change it, so neither command can overwrite another environment’s key by accident. (keys create --save-profile <name> names its profile explicitly; config set changes the profile it resolves.)
• The environment outranks the profile, so a PYLOTA_MAIL_KEY left in the environment keeps overriding a key saved in a profile. login prints a one-line warning to stderr when PYLOTA_MAIL_KEY is set and differs from the key it saved.
• --key on the command line is visible to other users through the process list on most systems. The CLI accepts it (scripts need it) but prints a one-line warning to stderr in human mode, suggesting PYLOTA_MAIL_KEY or a profile.
• The URL must be https:// unless the host is localhost, 127.0.0.1 or [::1]. A trailing /v1 or / is removed.
• The key must match ^pmk_(live|test)_[0-9a-hjkmnp-tv-z]{12}_[0-9a-hjkmnp-tv-z]{52}$ (Security §4.1) before it is sent anywhere; otherwise exit 3.

2.3 Key sources

• key_env: the variable must be set and non-empty, else exit 3 naming the variable.
• key_command: run once per invocation through sh -c (cmd /C on Windows) with stdin closed and a 10-second timeout; stdout is trimmed of surrounding whitespace. A non-zero exit, a timeout or an output that fails the key pattern is exit 3. Its stderr is passed through. The command line is shown in errors; its output never is.

2.4 Resolving names to IDs

Commands accept names where people think in names. resolve.rs turns them into IDs before the main request:

When a mail command needs an identity and none is given, the profile’s identity is used; an identity key uses its own identity (from GET /v1/me); otherwise exit 2 with “Pass –identity”.

When a tenant-scoped command needs a tenant and none is given: a tenant or identity key uses its own tenant; a platform key uses the profile’s tenant, else the default tenant (the one tenant with an empty address_suffix, created by setup). This is why pmail identities create --username bookings --display-name "Acme Car Hire" works with the platform key that setup leaves in the profile. GET /v1/me is called at most once per invocation and cached for that invocation only.

Three commands never fall back to the default tenant. jobs start needs --tenant and ignores the profile’s tenant (§18). usage and usage daily with a platform key send tenant_id only from --tenant or the profile’s tenant; without either the request carries none, and the API answers 400 invalid_request (exit 7), because a platform key must name the workspace whose usage it reads.

2.5 Cloudflare credentials

The commands that call the Cloudflare API or Wrangler with the operator’s own token are listed once, in CLI reference › Commands that use your Cloudflare token. They need:

• CLOUDFLARE_API_TOKEN (environment only; there is no flag, so it never appears in the process list). Missing: exit 3. It is never stored.
• The account ID: --account-id (a global flag, accepted by every command and used by those above), else CLOUDFLARE_ACCOUNT_ID, else the profile’s account_id, which setup writes, else PM_CF_ACCOUNT_ID from the rendered <dir>/wrangler.toml. Missing: exit 3.

The CLI passes both to Wrangler through the child’s environment, never as arguments. The permissions of this token, and of the Worker’s own PM_CF_API_TOKEN, are in one table: Deploy to Cloudflare › Create a Cloudflare API token.

The deployment directory is ./deploy unless --dir <path> is given. It holds wrangler.toml and .bundle/<version>/ (extracted releases). deploy/wrangler.toml doubles as setup’s record of the resource IDs it created, so no other state file exists.

The platform operations (dlq, keys rotate thread|link|cursor|web_bot_auth, jobs, waitlist invite) need no Cloudflare credentials: they are plain API calls with a platform key holding platform:ops (REST API › Platform operations). Neither do identity-keys, assertions create and http-sign, which are plain API calls too, and assertions verify and webhooks verify need no key at all.

2.6 AWS credentials

setup ses (§6.9), destroy --include-ses (§11) and the doctor’s ses check use the operator’s local AWS credentials, from the standard AWS sources: the environment variables AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY and AWS_SESSION_TOKEN, then the profile named by AWS_PROFILE (else default) in the shared files ~/.aws/credentials and ~/.aws/config. The exact resolution order and which further sources are supported (IAM Identity Center sessions, credential_process): verify at build time. There is no flag for a secret key, so none appears in the process list.

• No credentials found: exit 3 for setup ses and destroy --include-ses; the doctor’s ses check is skip.
• These credentials are never written to the config file, never uploaded to the Worker and never printed. The Worker gets its own access key, for the IAM user that setup ses creates, through wrangler secret put on stdin.

3. Output

3.1 Modes

• In JSON mode the document is the API response body, unchanged (FR-CLI-1). List commands print { "data": [ … ], "next_cursor": … }; with --all the CLI follows next_cursor (at most 10,000 items unless --limit says otherwise) and prints one document with every item and "next_cursor": null.
• Commands that are not a single API call (setup, setup ses, deploy, upgrade, doctor, destroy, secrets rotate-master, dlq redrive over several items, mcp config, webhooks verify, assertions verify, ask without a stream) print the documents defined in their sections.
• --json turns off every prompt. A command that needs an answer it was not given fails with exit 2 and says which flag to pass. --yes answers “yes” to confirmations except destroy’s typed confirmation (§11).
• Colour is used only when stdout is a terminal and NO_COLOR is unset.

3.2 Untrusted text in a terminal

Subjects, display names, snippets, filenames, bodies, answers and quotes come from email and are untrusted (API reference). In human and quiet modes every such string passes through output::terminal_safe before it is written:

• C0 controls except \n and \t, DEL, and C1 controls (U+0080–U+009F) are replaced with \u{FFFD}; this removes ANSI escape sequences, which could otherwise rewrite the screen or set the window title.
• Bidirectional controls (U+202A–U+202E, U+2066–U+2069) and zero-width characters (U+200B–U+200D, U+2060, U+FEFF) are shown as <U+202E>-style markers, so “Trojan Source” reordering is visible.
• In tables, newlines are shown as ⏎ and each cell is cut to its column width.

JSON mode prints strings exactly as the API returned them (JSON escaping makes them inert).

3.3 Errors

• Human mode prints to stderr:

  error: idempotency_conflict (409): This Idempotency-Key was used with a different request body.
    fix: Use a new Idempotency-Key for a different message, or resend the original body.
    request_id: req_01J9Z4…
  

• JSON mode prints the error envelope to stdout. Errors raised by the CLI itself use the same shape with CLI codes (cli_usage, cli_config, cli_prerequisite, cli_cloudflare, cli_aws, cli_verification, cli_doctor_failed, cli_timeout, cli_interrupted, cli_internal), retryable set as for the matching exit code, and request_id: null.

• A 404 without the service’s envelope is reported as upstream_not_found, exit 9, never as “not found”: it came from a proxy or a wrong host (Errors).

• Cloudflare API failures print the step, the HTTP status and every errors[].code and message from the Cloudflare envelope, plus a fix from a table of known codes (missing permission, zone not found, resource name taken in another jurisdiction).

• AWS API failures (setup ses) print the step, the HTTP status and the AWS error code and message. Request signatures, credentials and the Worker’s new access key are never printed.

3.4 Exit codes

Exit codes are part of the CLI contract (AGENTS.md: “do not silently change a public contract”). New codes may be added; existing ones never change meaning.

4. HTTP behaviour against the API

• All API calls go through the SDK (pylota_mail::Client). The CLI sets User-Agent: pmail/<version> (+https://github.com/PILOTAAI/pylota-mail).
• Timeouts: connect 10 s; request 30 s; wait uses timeout + 15 s; ask and streaming have no overall timeout but abort after 30 s without a byte (the server sends a keep-alive every 10 s).
• Idempotency keys. Mail sends (send, reply, reply-all, forward) take --idempotency-key. When it is omitted, the CLI generates pmail-<ulid> and prints it to stderr in human mode (and includes it in a CLI-generated error document in JSON mode), so a person can rerun the command with the same key after a network error. Every other POST gets a generated key per invocation, so the CLI’s own retries are safe. The exceptions are assertions create and http-sign: their endpoints ignore the header and never record it, because each call mints a new value and stores nothing, so the CLI sends none and a retry simply mints again.
• Retries. A request is retried at most 3 times when the error is retryable by Errors › How a client should retry: network errors and 5xx with backoff 0.5 s, 1 s, 2 s plus up to 250 ms jitter; 429 rate_limited after Retry-After (at most 60 s; longer waits are reported, not slept). Retries reuse the same idempotency key. 409 request_in_progress is retried after 1 s, at most 5 times.
• Cursors are passed through; --all stops on 410 cursor_expired with exit 6 and the items so far are not printed (a partial list would be mistaken for a complete one).

5. The Cloudflare client

cloudflare::Client talks to https://api.cloudflare.com/client/v4 with Authorization: Bearer $CLOUDFLARE_API_TOKEN.

• Responses use Cloudflare’s envelope { success, errors[], messages[], result, result_info }. A non-2xx status or success: false becomes CliError::Cloudflare with the step name.
• List calls follow result_info pages (page, per_page) or cursor where the endpoint uses one.
• Retries: 429 (honouring Retry-After) and 5xx up to 5 times with backoff 1, 2, 4, 8, 16 s. 4xx is never retried.
• Find, then create. Every create is preceded by a lookup by name, and the create only runs when the lookup finds nothing. A create that fails because the name exists (a race with a parallel run) is followed by one more lookup. This is what makes setup safe to re-run (FR-OPS-1).
• Request and response bodies are never logged. --verbose logs method, path (with the account and zone IDs), status and duration to stderr.

6. setup

pmail setup --account-id <account-id> --domain mail.example.com --mail-domain agents.example --jurisdiction eu

6.1 Flags

Billing stays off: setup never writes PM_BILLING, so a self-hosted deployment needs no Stripe account (FR-BILL-12), and the default tenant’s billing mode is disabled. Sign-up stays closed: setup writes PM_SIGNUP = "closed" (FR-CON-8), so people join a self-hosted deployment as the setup owner or by invitation.

SES is not part of setup. A deployment that wants dns_records, send_only or the SES failover runs pmail setup ses afterwards (§6.9).

6.2 Preflight

All checks run before anything is created; each failure is exit 2, 3 or 10 with a fix.

1. CLOUDFLARE_API_TOKEN and the account ID are present (§2.5).
2. --domain is a valid host name (A-label after IDNA conversion, no port, no path) and differs from --mail-domain; so is --console-host when given. --mail-domain is a valid domain. --jurisdiction is eu or default. --daily-send-quota is a positive integer. --backup-bucket is a valid R2 bucket name other than pylota-mail-blobs.
3. node --version reports 22 or later; then npx --yes wrangler@4.139.0 --version prints 4.139.0 (this also fills the npx cache, so later steps do not download).
4. The mail domain is a zone apex: GET /zones?name={mail_domain}&account.id={account_id} returns a zone whose name equals the mail domain. If it does not, the CLI repeats the call for each parent label to name the zone the domain belongs to, and fails with “agents.example is not a zone apex in this account (its zone is example)”. Catch-all routing exists only on an apex (Architecture §7).
5. The API host’s zone is found the same way (the longest parent that is a zone in the account), so Wrangler can attach the Custom Domain; and the console host’s zone, when it differs.
6. Existing mail (H5). GET /zones/{zone_id}/dns_records?type=MX&name.exact={mail_domain}. The expected Email Routing MX hosts are read from GET /zones/{zone_id}/email/routing/dns, never hard-coded. Any other MX record: without --replace-mx, stop with exit 10 (a prerequisite not met: the JSON error code is cli_prerequisite with details.reason = "existing_mx"), and the fix “This domain already receives mail elsewhere; use a dedicated domain, or pass –replace-mx to stop that mail”. With --replace-mx (and a confirmation unless --yes), each foreign record is deleted with DELETE /zones/{zone_id}/dns_records/{id} in step 7.
7. Optional, warn-only: the four models in the template’s [vars] are listed by GET /accounts/{account_id}/ai/models/search?search={name} (endpoint and parameter: verify at build time). A missing model is a warning, because a deployment can override it later.

6.3 Steps

Each step prints created, exists, updated or skipped with the resource and its ID. The Idempotency column says how a re-run behaves.

6.4 Why this order

 resources (2-10) ──► render (11) ──► D1 schema (12) ──► Worker (13) ──► secrets (14)
                                                                             │
   default tenant (21) ◄── bootstrap key (19, 20) ◄── catch-all (17) ◄── health (15, 16)
         │
         ▼
   system identity (22) ──► mail test, PM_TRUSTED_AUTHSERV_ID (23) ──► summary (24)

• Resources before the render. The rendered file needs the D1 ID and the rate-limit namespace IDs, and Wrangler refuses bindings to queues or indexes that do not exist.
• Schema before code (step 12 before 13). The Worker’s first request, cron or queue batch reads D1; an empty database would fail them. This is the same rule deploy follows for every release (§8.4).
• Code before secrets (13 before 14). wrangler secret put attaches a secret to an existing Worker, creating and deploying a new version each time. Until all required secrets exist, the Worker answers 503 unavailable to everything (Observability §7.1), which is harmless because no mail is routed to it yet.
• Catch-all last among the Cloudflare steps (17 after 13–15). Email Routing was enabled in step 7, so MX records exist from then on, but without a catch-all every recipient is unknown and Cloudflare refuses the mail at SMTP time. A catch-all that pointed at a missing Worker, or at a Worker without secrets, would accept mail that then could not be stored. With this order, mail to the platform domain is refused until the Worker can store it durably, and accepted from the moment it can. Mail sent during setup is refused, never lost.
• Keys, domain row and tenant after the catch-all, because they need a working Worker: the tenant’s TenantQuota object ID and the domain’s DomainMonitor object ID can only be minted inside the Worker, and the owner’s sign-in link is sent by it.
• System identity after the default tenant (22 after 21), because its row belongs to that tenant; the owner’s sign-in link waits for it (the Worker retries the send until the system identity’s mailbox exists, at most 2 minutes).
• Mail test last (23): it needs the catch-all, the system identity’s domain and a key, and its result is the authserv-id that Cloudflare’s MX stamps (spike S2 records it first).

Setup therefore performs the first deploy itself. pmail deploy run straight after it finds nothing to change and exits 0 (§8.9), so the documented sequence setup, deploy, keys create works as written.

6.5 The bootstrap key

The first API key cannot be created through the API (there is no key to authenticate with), and the Worker stores only hex(HMAC-SHA256(PM_KEY_PEPPER, key)) (Security §4.1). Setup is the only time the CLI knows the pepper, because it generated it. The bootstrap path:

1. If the current profile has a key and GET /v1/me returns 200 with level: "platform", skip.
2. Read the state: is PM_KEY_PEPPER among the secret names (step 14), and SELECT COUNT(*) AS n FROM api_keys through the D1 query API.
3. Decide:

When. The decision is taken in step 14, when the secret names are listed; the D1 migrations of step 12 have created api_keys, so it can be counted. Rows 1, 2 and 4 upload the new pepper there, with the other missing secrets, and P stays in memory until step 19 inserts the key. Row 3 uploads nothing and stops setup in step 19, after the profile’s key was tried (point 1). With --rotate-pepper, point 1 is not applied.

4. Generate the key natively with core::keys and the OS CSPRNG: lookup (12 characters, 60 random bits) and secret (52 characters, 32 random bytes), giving pmk_live_{lookup}_{secret}.
5. Insert it and an audit row in one D1 query request (two statements; see §8.5 on atomicity):

INSERT INTO api_keys (id, lookup, hash, name, level, tenant_id, identity_id, mode,
                      permissions_json, created_by_key_id, expires_at, created_at)
VALUES (?1, ?2, ?3, 'setup-bootstrap', 'platform', NULL, NULL, 'live', ?4, NULL, ?5, ?6);

INSERT INTO audit_log (id, tenant_id, actor_key_id, action, target_type, target_id,
                       details_json, request_id, created_at)
VALUES (?7, NULL, NULL, 'key.create', 'api_key', ?1, '{"via":"pmail setup"}', NULL, ?6);

• ?1 key_ + ULID; ?3 lower-case hex of HMAC-SHA256(P, whole key string); ?4 the JSON array of every permission a platform key may hold (API reference): every permission except identities:sign, which platform keys cannot hold (Agent signing keys §6); ?5 now + 24 h in Unix milliseconds; ?6 now; ?7 aud_ + ULID. The D1 query API takes parameters as strings; SQLite’s integer affinity stores ?5 and ?6 as integers.

6. Save the URL (https://{api_host}) and the key in the profile (§2.1), and drop P from memory.

The bootstrap key expires after 24 hours on purpose. pmail keys create --level platform --name first-key --permissions <list> creates the long-lived key; a platform key needs an explicit --permissions (§18), so setup’s summary prints the whole command with every permission a platform key may hold. When it runs interactively with a profile whose key is named setup-bootstrap, it asks whether to store the new key in that profile and revoke the bootstrap key (DELETE /v1/keys/{id}); --save-profile <name> stores it without asking, and the bootstrap key then expires on its own.

6.6 The platform domain row

The domains row needs a DomainMonitor object ID (monitor_do_id NOT NULL, Data model), which only the Worker can mint (jurisdiction-bound unique IDs). Setup writes everything it learned from the Cloudflare API and leaves the monitor ID empty; the Worker completes the row:

INSERT INTO domains (id, tenant_id, name, kind, method, inbound, zone_id, is_apex, routing_mode,
                     transport, reply_token, receiving, sending, state, state_changed_at,
                     ownership_token, event_subscription_id, records_json, monitor_do_id,
                     created_at, updated_at)
VALUES (?1, NULL, ?2, 'platform', 'platform', 'routing', ?3, 1, 'catch_all',
        'cloudflare', 'subaddress', 1, 1, 'pending', ?4,
        ?5, ?6, ?7, '',
        ?4, ?4)
ON CONFLICT(name) DO UPDATE SET
  zone_id = excluded.zone_id, ownership_token = excluded.ownership_token,
  event_subscription_id = excluded.event_subscription_id,
  records_json = excluded.records_json, updated_at = excluded.updated_at;

Requirement on the Worker (owned by Identities, addresses and domains): the * * * * * cron selects SELECT id, kind FROM domains WHERE monitor_do_id = '' LIMIT 20, mints a DomainMonitor ID in PM_JURISDICTION for each, sets monitor_do_id, sends DomainRequest::Init, and emits domain.created for rows with a tenant_id. The same hook serves domains that pmail domains add onboarded with the local token (§18.1). Setup polls SELECT monitor_do_id FROM domains WHERE kind = 'platform' for up to 2 minutes and reports monitor: started or a warning naming the cron.

6.7 Re-runs and failures

• Every step can be repeated. A failed run stops at the failing step with its Cloudflare error and fix; running the same command again continues, because every earlier step finds its resource.
• Changing --mail-domain, --domain or --jurisdiction on a re-run against a deployed account is refused (exit 2): the platform domain is part of every address and the jurisdiction is fixed at creation. The values are read from the rendered file.
• Setup never deletes anything, except foreign MX records with --replace-mx.
• Interrupting setup (Ctrl-C) finishes the current HTTP request, writes nothing further and exits 130.

6.8 Output

Human mode prints one line per step and then:

Pylota Mail 1.0.0 is running at https://mail.example.com
Platform domain: agents.example (Email Routing catch-all → pylota-mail, Email Sending onboarded)
Default tenant: ten_01JA… (addresses look like name@agents.example)
Console owner: sam@acmecarhire.example (sign-in link sent)
Profile "default" holds a bootstrap key that expires in 24 hours.
Next: pmail keys create --level platform --name first-key --permissions tenants:manage,platform:ops,…
      pmail doctor --mail-test

The real summary prints the --permissions list in full (every permission except identities:sign).

JSON mode prints { "version", "api_url", "platform_domain", "tenant_id", "steps": [ { "step", "status", "resource", "id" } ], "secrets": { … } }, where secrets is present only with --print-secrets. Without --print-secrets, generated secrets are never written to stdout, a file or a log.

6.9 setup ses

pmail setup ses --region eu-west-2 [--allow-non-eu] [--prefix <prefix>] [--dir <path>] [--yes]

Connects the deployment to Amazon SES once, for the dns_records, send_only and smtp_relay (inbound: ses) methods and for the SES failover of J5. The resources and their settings are owned by Domains on any DNS host §4.2; this section decides the CLI’s part. It runs after setup, against the deployment in --dir.

It uses the operator’s local AWS credentials (§2.6), plus the Cloudflare credentials of §2.5 for wrangler secret put, the deploy and the platform identity’s DNS records. Like setup, it is idempotent and reads before it writes: every step looks the resource up first, and creates or updates it only when it is missing or differs. Each step prints created, exists, updated or skipped.

Checks before anything is created (each stops the command):

1. deploy/wrangler.toml exists, and GET https://{PM_API_HOST}/health answers with the CLI’s version (the Worker must confirm the SNS subscriptions later, and step 10 deploys). A different version stops with exit 2 and the fix pmail upgrade, so setup ses never changes the version as a side effect. PM_JURISDICTION and PM_PLATFORM_DOMAIN are read from the file.
2. Region. --region must be one of the regions that receive mail (the list on AWS’s endpoints page, read 2026-10-09, compiled into the CLI); otherwise exit 2, because dns_records could not receive. With PM_JURISDICTION = "eu", a region other than eu-central-1, eu-west-1, eu-west-2 (London), eu-south-1, eu-west-3 and eu-north-1 is refused with exit 2 unless --allow-non-eu is given (N30). For this check eu means “EU or UK”: the UK has an EU adequacy decision under the GDPR (European Commission adequacy decisions, renewed 19 December 2025, read 2026-10-09), so London is an acceptable data location. It differs from Cloudflare’s eu jurisdiction for D1, R2 and Durable Objects, which means the EU only.
3. Account. SES GetAccount in the region. Without production access, the command prints the AWS console steps to request it and stops with exit 14; nothing has been created. On the Essentials plan ($0.16 per 1,000 against $0.10 à la carte, SES pricing read 2026-10-09) it prints a warning and continues. How the plan is read from the account: verify at build time; if it cannot be read, the warning names both prices.

Steps, in order. The numbers in brackets are the rows of Domains on any DNS host §4.2.

AWS operation and field names beyond those cited in Domains on any DNS host (for example the receipt-rule-set calls, CreateAccessKey and the subscription status): verify at build time.

Exit codes (§3.4):

JSON mode prints { "region", "rule_set", "steps": [ { "step", "status", "resource", "id" } ], "policy": { … }, "warnings": [ … ] }. The access key never appears in it.

7. Rendering wrangler.toml

bundle/render.rs renders <dir>/wrangler.toml from the bundle’s deploy/wrangler.toml.tmpl (or the repository’s template with --from-source). The output is the file in Rust workspace §8.

1. Inputs, highest priority first: the values setup or setup ses learned in this run (resource IDs, flags); the values in the existing <dir>/wrangler.toml, if any; the template’s defaults.
2. Preserved operator edits. Every key under [vars] keeps its existing value, so a deployer who sets PM_TRUSTED_AUTHSERV_ID or PM_EMBED_MODEL in the file keeps it across deploy and upgrade. PM_CONSOLE_HOST (default: the API host), PM_SIGNUP (default "closed"), PM_WEB_BOT_AUTH (default "off", Agent signing keys §9), PM_IDENTITY_KEY_OVERLAP_DAYS (default "7") and PM_NOTIFICATIONS (default "on", Notifications) are always written, so the operator sees them. Optional variables are written only when set: PM_AI_GATEWAY, PM_SES_REGION, PM_SES_SNS_TOPIC_ARN, PM_SES_INBOUND_BUCKET, PM_SES_INBOUND_TOPIC_ARN, PM_SES_INBOUND_QUEUE_URL, PM_SES_RULE_SET, PM_CF_SUBDOMAIN_SETUP, PM_DAILY_SEND_QUOTA, PM_BACKUP_BUCKET, PM_SCANNER_URL, PM_SECURITY_CONTACT, and the other console, sign-up and billing variables of Configuration › Variables. The [observability.traces] table is preserved too: its enabled and head_sampling_rate keep their existing values, and the template’s default (enabled = false) is written only when the table is missing. Staging sets enabled = true and head_sampling_rate = 0.1 once, and deploy and upgrade keep it. Staging carries only synthetic mail (Testing §10).
3. Owned sections. Bindings, Durable Object migrations, queues, cron triggers, limits and observability come from the template. They include the Q_DELIVERY producer (used only by POST /v1/platform/dlq/{dlq_id}/redrive to republish dead-lettered delivery events), the six Durable Object bindings including NOTIFY (class Notifier, Notifications §8), the six rate-limit bindings including RL_SIGNIN (10 requests per 60 s per client IP, Cloud sign-up §10) and RL_SIGN (600 signing calls per 60 s per identity, Agent signing keys §6), a second Custom Domain route when PM_CONSOLE_HOST differs from PM_API_HOST, and, when PM_BACKUP_BUCKET is set, the BACKUP R2 binding in the deployment’s jurisdiction. Edits to them are not preserved; the renderer prints a unified diff of what it changed and, in interactive mode, asks before writing when a non-[vars] line would change.
4. Placeholders {…} that remain after merging are an error naming the missing value.
5. Validation: the result must parse as TOML; PM_PLATFORM_DOMAIN, PM_API_HOST and PM_JURISDICTION must equal the values in the D1 platform domain row once it exists (a mismatch means the file was copied from another deployment: exit 3).
6. The file is written atomically, mode 0644 (it holds no secrets).

8. deploy

pmail deploy [--version <v>] [--from-source [--source-dir <path>]] [--gradual] [--stages <list>] [--stage-wait <duration>] [--force] [--dir <path>]

8.1 Bundle download

1. The version is --version, else the CLI’s own version. A version newer than the CLI is refused (exit 2): the CLI implements the setup steps and migration runner for its own release.
2. GET https://api.github.com/repos/PILOTAAI/pylota-mail/releases/tags/v{version} with Accept: application/vnd.github+json and X-GitHub-Api-Version: 2026-03-10; a 404 is exit 2 (“no such release”). From assets[], take the browser_download_url of pylota-mail-worker-{version}.tar.gz, SHA256SUMS and SHA256SUMS.sig.
3. Download each to <dir>/.bundle/{version}.partial/ with caps: SHA256SUMS ≤ 64 KB, SHA256SUMS.sig ≤ 4 KB, the tarball ≤ 64 MiB. HTTPS only; at most 5 redirects, each to an https URL. HTTPS_PROXY is honoured.

8.2 Signature and checksums

Choice: minisign (Ed25519 signatures in the minisign format), verified with the minisign-verify crate (pin at build time; “a small Rust library with no external dependencies”, crates.io, read 2026-10-09). The SHA256SUMS.sig file produced by cargo xtask release (Rust workspace §9) is a minisign signature of SHA256SUMS.

Why minisign rather than cosign:

• Offline and self-contained. The public key is compiled into pmail; verification needs no network service. Keyless cosign verification depends on Sigstore’s certificate authority and transparency log being reachable and on trusting an OIDC identity, which adds failure modes to every deploy.
• Small trusted code. One dependency-free crate doing Ed25519 over a short file, against the Sigstore client stack (TUF, X.509, Rekor clients) compiled into a CLI that must build for five targets.
• Provenance is still available. Releases also carry GitHub build provenance from actions/attest@v4, verifiable with gh attestation verify (Security). That is the deeper supply-chain check for those who want it; minisign is the mandatory gate on every deploy.

Verification:

1. Parse SHA256SUMS.sig (untrusted comment, signature line, trusted comment, global signature). The signature’s key ID must equal one of the compiled-in key IDs. The CLI carries two keys, current and next, so the signing key can be rotated with a release that adds the next key before it is used.
2. Verify the signature over the exact bytes of SHA256SUMS, and the global signature over the signature plus the trusted comment. The trusted comment must be pylota-mail v{version}, so a valid signature from another release cannot be replayed.
3. Parse SHA256SUMS: lines <64 lower-case hex>␠␠<filename>; filenames match ^[A-Za-z0-9._-]{1,128}$; no duplicates.
4. Compute SHA-256 of the tarball while it streams to disk; it must equal its line. A missing line, a mismatch, or any signature failure is exit 11, the partial directory is deleted, and nothing is deployed. There is no flag to skip verification (FR-OPS-2).

8.3 Extraction

The tarball is extracted to <dir>/.bundle/{version}.partial/ and renamed to <dir>/.bundle/{version}/ when complete. Rules:

• Only regular files and directories. Symbolic links, hard links, devices and FIFOs are refused.
• Every path is relative, has no .. component, no leading /, no drive prefix, and stays inside the target after normalisation. At most 1,000 entries and 128 MiB unpacked.
• Expected contents: build/index.js, build/index_bg.wasm, build/worker/shim.mjs, migrations/d1/*.sql, deploy/wrangler.toml.tmpl, VERSION. VERSION must equal the requested version. Any missing file is exit 11.

8.4 Order of a deploy

verify bundle ─► render wrangler.toml ─► index generation check (§8.7)
      ─► D1 migrations ─► code (wrangler deploy, or gradual §8.6) ─► health ─► doctor subset

• Migrations before code. D1 changes are expand-then-contract (Architecture §7): a release only adds what its code needs, so the running (older) code keeps working against the expanded schema while the new code rolls out. Durable Object SQLite migrations are applied by each object on wake, idempotently (J9); the CLI does not touch them.
• A migration failure stops the deploy before any code changes (exit 10).

8.5 D1 migrations

bundle/migrate.rs applies migrations/d1/NNNN_name.sql in numeric order through POST /accounts/{a}/d1/database/{database_id}/query:

1. SELECT name FROM sqlite_master WHERE type = 'table' AND name = 'schema_migrations'. When it is absent, the database is new and every migration is pending (0001 creates schema_migrations).
2. SELECT version FROM schema_migrations.
3. For each file with a version not in the table, send one request whose sql is the file’s text followed by INSERT INTO schema_migrations (version, applied_at) VALUES ({version}, {now_ms});. The query API runs multiple statements as a batch.
4. Versions present in the table but absent from the bundle (the database is newer than the code being deployed) are allowed for a one-release rollback and reported as a warning; more than one such version is refused (exit 10), matching the expand-then-contract rule.

Whether a multi-statement request to the D1 query API is atomic is not stated in the API reference. Spike S1 checks it: its pass criteria include “a multi-statement D1 query-API request is atomic” (Design › Spikes). Fallback if it is not: every migration file must be re-runnable (CREATE TABLE IF NOT EXISTS, CREATE INDEX IF NOT EXISTS, INSERT OR IGNORE), the schema_migrations insert stays the last statement of the request, and a CI lint over migrations/d1/ enforces both from then on. A request that fails part-way is then simply sent again by the next pmail deploy. Until v1.0 there is one migration, 0001_init.sql (Build plan › M5).

Local integration tests apply the same files with wrangler d1 migrations apply --local (Testing §6.1); that path records Wrangler’s own table in the throwaway local database and never meets a deployed one.

8.6 Code deploy and the gradual flag

Default (--gradual off). npx --yes wrangler@4.139.0 deploy --config <dir>/wrangler.toml --message "pmail deploy v{version}", run with the bundle directory as working directory, so main = "build/index.js" resolves. Wrangler’s output is captured; on failure its last 40 lines are printed and the exit code is 10.

--gradual (the default for upgrade). Versions follow the architecture’s rollout, 10% → 50% → 100% (Architecture §7):

1. Durable Object class changes force a full deploy. If the rendered [[migrations]] tags differ from the deployed ones (read from the previous rendered file), the change cannot be uploaded as a version (Cloudflare deployment management, read 2026-10-09), so the CLI says so and uses the default path at 100%.
2. wrangler versions upload --config … --message "pmail v{version}" --tag v{version} and read the new version ID from its output. wrangler deployments list gives the currently deployed version ID.
3. Smoke test at 0%: wrangler versions deploy {new}@0% {old}@100% -y, then GET https://{api_host}/health with Cloudflare-Workers-Version-Overrides: pylota-mail="{new}" must return 200 with the new version.
4. For each stage p in --stages (default 10,50,100): wrangler versions deploy {new}@{p}% {old}@{100-p}% -y (at 100: {new}@100%), then wait --stage-wait (default 10 minutes; 0 allowed), polling every 30 s: /health with the override header, and the alerts and dlq doctor checks.
5. Abort on any failure, on Ctrl-C, or on a firing alert that was not firing before the deploy: wrangler versions deploy {old}@100% -y, report which check failed, exit 10. D1 migrations already applied stay (they are expansions).

During a gradual deployment each Durable Object runs one version at a time (Gradual deployments with Durable Objects, read 2026-10-09); mailbox schema migrations run on wake and are idempotent (J9).

8.7 Index generation changes

Search §7.3 defines the re-embed process. The CLI’s part runs in every deploy and upgrade, after rendering and before migrations:

1. Read PM_EMBED_MODEL from the rendered [vars], the index bound to VECTORS ([[vectorize]]), and whether a VECTORS_NEXT binding and PM_EMBED_MODEL_PREVIOUS are present.
2. Read the model of the bound index from its description (GET /accounts/{a}/vectorize/v2/indexes/{name}; setup wrote pylota-mail generation=N embed_model=…).
3. Decide:

doctor reports a completed job that has not been finalised as a warn on bindings, with the fix pmail deploy.

VECTORS_NEXT and PM_EMBED_MODEL_PREVIOUS are defined by Search §7.3 and listed in Configuration › Bindings and › Variables.

8.8 --from-source

Builds from a local checkout of the repository at the matching tag, named by --source-dir (default: the current directory; a directory without crates/worker is exit 2):

1. Check rustup target list --installed includes wasm32-unknown-unknown, else exit 10 with the install command.
2. cargo install worker-build --version 0.8.7 --locked (skipped when worker-build --version already prints 0.8.7), then worker-build --release in <source-dir>/crates/worker (Rust workspace §8).
3. Use the checkout’s migrations/d1/ and deploy/wrangler.toml.tmpl. No signature applies; the CLI prints the commit (git rev-parse HEAD) and a warning that the build is unverified.

--from-source avoids the GitHub Releases download, not the network: Cargo still needs crates.io for worker-build and the workspace’s dependencies, unless the crates are vendored (cargo vendor) and worker-build 0.8.7 is already installed, and npx still fetches Wrangler from the npm registry unless it is in the npx cache. What else worker-build downloads while it builds: verify at build time.

8.9 No-op redeploys

After a successful deploy the CLI writes # pmail: deployed v{version} sha256={hash of the rendered file without this line} as the last line of wrangler.toml. deploy exits 0 without calling Wrangler when that line matches, migrations are up to date, and /health reports the same version. --force deploys anyway.

8.10 Output

Verified pylota-mail-worker-1.0.0.tar.gz (minisign key 7A3F…, sha256 9c1e…)
Rendered deploy/wrangler.toml (no changes)
D1 migrations: 0 pending
Deployed v1.0.0 (version 095f00a7-…) to https://mail.example.com
Health: ok

JSON: { "version", "worker_version_id", "migrations_applied": [ … ], "gradual": { "stages": [ … ] } | null, "index_generation": "unchanged|started|finalised|canceled|in_progress" }.

9. upgrade

pmail upgrade [--stages 10,50,100] [--stage-wait 10m] [--no-gradual] [--dir <path>]

1. GET https://api.github.com/repos/PILOTAAI/pylota-mail/releases/latest. If its tag is newer than the CLI, print “pmail {cli} is older than the latest release {latest}; install the new CLI first” with the install commands, and exit 2. The CLI’s version decides the Worker version.
2. GET https://{api_host}/health. If the deployed version equals the CLI’s, exit 0 (“up to date”). If the deployed version is newer than the CLI’s, refuse (exit 2): that would be a rollback, which is pmail deploy --version <v>.
3. Run deploy with --gradual (unless --no-gradual), including the index generation check.
4. Run doctor and print its result. A doctor failure after an upgrade is exit 12; the new version stays deployed (the gradual stages already checked health and alerts).

10. doctor

pmail doctor [--mail-test] [--check <name>]… [--dir <path>]

The checks, their failure conditions and fixes are defined in Observability §7.2. This section defines how the CLI runs them.

• Each check returns pass, warn, fail or skip (a prerequisite is missing, for example no API key for alerts). Checks run concurrently, at most 8 at a time, each with a 20-second timeout (mail_test: 150 s); a timeout is fail with reason timeout.

• A Cloudflare API error inside a check makes that check fail, with the step and the Cloudflare error codes in detail (the one exception is quota, below). doctor therefore never exits 10.

• Human output: one line per check, then a summary.

  pass  dns.platform                 MX, SPF, DKIM, DMARC match on both resolvers
  fail  routing.catch_all            catch-all is disabled
        fix: pmail setup (step 17), or PUT /zones/{zone_id}/email/routing/rules/catch_all …
  warn  security_txt                 PM_SECURITY_CONTACT is not set
  13 passed, 1 warning, 1 failed
  

• JSON: { "checks": [ { "name", "status", "detail", "fix" } ], "summary": { "pass", "warn", "fail", "skip" } }.

• Exit 0 with no fail; 12 otherwise.

• --check runs only the named checks.

Data sources:

--mail-test. Needs a key that holds, in the default tenant, identities:read and identities:write (step 1), messages:send (step 2), search:read (wait, step 3), messages:read (the raw message, step 4) and erasure:manage (step 5). The platform key that setup creates holds them; without one of them the check is fail with the missing permission in detail.

1. Create or reuse the identity pmail-doctor in the default tenant (client_id: "pmail:doctor", owner = the setup owner or postmaster@{mail_domain} as a placeholder the operator sees).
2. Send from it to its own platform address pmail-doctor@{mail_domain}, subject pmail doctor {ulid}, Idempotency-Key: pmail-doctor-{ulid}.
3. GET /v1/identities/{id}/wait?subject_contains=pmail%20doctor%20{ulid}&timeout=60, twice at most.
4. pass when the inbound copy arrives with trust.verdict: "pass". The detail prints the Authentication-Results authserv-id seen on the raw message (GET …/messages/{id}/raw, first such header), for PM_TRUSTED_AUTHSERV_ID.
5. Erase the two test messages (DELETE …/messages/{id}), so the check leaves no mail behind.

11. destroy

pmail destroy [--dry-run] [--confirm <platform-domain>] [--skip-erasure] [--keep-dns] [--include-ses] [--dir <path>]

Deletes the deployment and every Cloudflare resource setup created, and, with --include-ses, the AWS resources setup ses created. It is irreversible: point-in-time recovery cannot bring back a deleted database or bucket.

Safety.

• The typed confirmation is mandatory: interactive runs ask the operator to type the platform domain; non-interactive runs need --confirm agents.example matching PM_PLATFORM_DOMAIN. --yes does not replace it.
• --dry-run prints the plan (every resource with its ID, the tenants and their identity counts) and exits 0 without changing anything. Every real run prints the same plan first.
• The resources are found from the rendered file and verified by name in the account before anything is deleted, so a stale file cannot point the command at someone else’s resources.
• AWS resources. When the rendered file holds PM_SES_REGION, the plan lists the resources setup ses created (§6.9: the names there and the PM_SES_* variables). Without --include-ses they are marked “left in place” and are not touched, and the final output repeats the list, warning that the IAM user’s access key stays valid until someone deletes it in the AWS console. With --include-ses, the local AWS credentials (§2.6) are checked before anything is deleted (exit 3 without them) and step 4 deletes the resources.

Order.

1. Stop new mail. PUT /zones/{z}/email/routing/rules/catch_all with "enabled": false.
2. Erase every tenant through the product, unless --skip-erasure: for each tenant, POST /v1/erasure-requests {"tenant_id": …, "scope": "tenant", "reason": "pmail destroy"}, then poll GET /v1/erasure-requests/{id} until completed or completed_with_holds (deadline 2 hours; exit 13 after it, and a re-run resumes). This wipes mailboxes, R2 objects and vectors through the tested erasure path and removes tenant domains’ routing, sending and subscriptions. An erasure skips threads under a legal hold and ends completed_with_holds, listing them in its receipt (FR-PRV-4). Deleting the storage in steps 5 and 6 would destroy that held mail, so the CLI then lists the held threads per tenant and stops with exit 6 (conflict) before step 3. A person releases the holds (or exports the mail and then releases them) and runs destroy again; the erasure re-runs and now removes those threads. --skip-erasure is for a Worker that no longer answers.
3. Tear down remaining domains. For each row left in domains (always the platform domain), the removal steps of Identities, addresses and domains › Domain removal with the local token: literal rules, catch-all disabled, DELETE /zones/{z}/email/routing/dns (unless --keep-dns), DELETE /zones/{z}/email/sending/subdomains/{tag}, the event subscription, and the ownership TXT. SES identities are left to step 4.
4. Amazon SES resources (only with --include-ses; otherwise listed as above). With the local AWS credentials, in the reverse order of §6.9: the two HTTPS subscriptions; the Worker’s access key, then the IAM user pylota-mail-worker and its policy; the SES identities of every domain row that still has ses_identity (left by --skip-erasure) and the platform identity, with the platform identity’s DKIM CNAMEs removed from its zone through the Cloudflare API; the configuration set, its event destination and the delivery-events topic; the receipt rule pm-deliver, and the rule set pylota-mail only when setup created it (an operator’s own active rule set is kept, without the rule); the SQS queue and its subscription; the inbound SNS topic; the inbound S3 bucket, emptied first (it holds raw mail for at most 14 days). Each step reads first and treats AWS’s not-found error as done; any other AWS error is exit 14, and a re-run continues. Operation names beyond those cited in Domains on any DNS host §4.2: verify at build time.
5. Delete the Worker: npx --yes wrangler@4.139.0 delete --name pylota-mail. Wrangler describes this as deleting the Worker and its associated resources; whether the Durable Object namespaces’ storage is removed with it is verified at build time. After step 2 no mail content remains in them.
6. Delete storage: every Vectorize index named pm-mail-chunks* (DELETE /accounts/{a}/vectorize/v2/indexes/{name}); the ten queues (DELETE /accounts/{a}/queues/{queue_id}); the R2 bucket (DELETE /accounts/{a}/r2/buckets/pylota-mail-blobs with the jurisdiction header), and the BACKUP bucket when PM_BACKUP_BUCKET is set. R2 refuses to delete a bucket that still holds objects; staging objects expire within a day by the lifecycle rule, so the CLI reports the bucket as pending and a re-run the next day finishes. The tenant erasures of step 2 sweep the backup bucket too (Privacy §5.4); an object left in it is reported the same way. Last, the D1 database (DELETE /accounts/{a}/d1/database/{id}).
7. Remove the profile’s key (it no longer works) and rename <dir>/wrangler.toml to wrangler.toml.destroyed.

Each step is idempotent; a 404 carrying Cloudflare’s own “not found” code counts as done, any other 404 is an error (the same rule as domain removal).

12. Secrets

12.1 secrets rotate-master

The procedure is Security §6.2. The CLI’s part:

1. Refuse if PM_MASTER_KEY_NEXT already exists (a rotation is in progress) unless --resume.

2. Generate K2 (32 bytes, OS CSPRNG) and compute kid(K2) = first 8 bytes of SHA-256(K2), lower-case hex (Security §7.2). Upload it with wrangler secret put PM_MASTER_KEY_NEXT (value on stdin).

3. Poll every 60 s through the D1 query API until the count is 0:

   SELECT
     (SELECT COUNT(*) FROM webhook_endpoints WHERE secret_enc NOT LIKE 'pm1.' || ?1 || '.%')
   + (SELECT COUNT(*) FROM webhook_endpoints WHERE prev_secret_enc IS NOT NULL
                                               AND prev_secret_enc NOT LIKE 'pm1.' || ?1 || '.%')
   + (SELECT COUNT(*) FROM identity_keys WHERE private_enc NOT LIKE 'pm1.' || ?1 || '.%')
   + (SELECT COUNT(*) FROM signing_keys WHERE ciphertext NOT LIKE 'pm1.' || ?1 || '.%')
   + (SELECT COUNT(*) FROM domains WHERE smtp_sealed IS NOT NULL
                                     AND smtp_sealed NOT LIKE 'pm1.' || ?1 || '.%')
   + (SELECT COUNT(*) FROM domains WHERE smtp_pending_sealed IS NOT NULL
                                     AND smtp_pending_sealed NOT LIKE 'pm1.' || ?1 || '.%')
   + (SELECT COUNT(*) FROM users WHERE totp_sealed IS NOT NULL
                                   AND totp_sealed NOT LIKE 'pm1.' || ?1 || '.%')
   + (SELECT COUNT(*) FROM users WHERE recovery_codes_sealed IS NOT NULL
                                   AND recovery_codes_sealed NOT LIKE 'pm1.' || ?1 || '.%')
   + (SELECT COUNT(*) FROM oauth_states WHERE pkce_sealed NOT LIKE 'pm1.' || ?1 || '.%') AS remaining;
   

   The columns are every value sealed under PM_MASTER_KEY (Security §7.2), the same set the Worker’s re-seal sweep covers.

   printing the count each time. With --resume, K2 is not known; the CLI reads the target kid from the most common kid among rows already re-sealed and asks for confirmation.

4. Upload PM_MASTER_KEY = K2, then delete PM_MASTER_KEY_NEXT (wrangler secret delete PM_MASTER_KEY_NEXT --name pylota-mail), then drop K2 from memory.

5. Deadline 24 hours (exit 13; --resume continues).

PM_MASTER_KEY_NEXT is defined by Security §6.2 and listed in Configuration › Secrets. While it is set, doctor warns (secrets).

12.2 Signing keys: keys rotate thread|link|cursor|web_bot_auth

pmail keys rotate thread|link|cursor|web_bot_auth [--revoke-previous] [--yes]

The keys that sign thread tokens, links and console tokens, search cursors, and Web Bot Auth HTTP signatures with their key directory are not Worker secrets: the Worker generates them into D1 signing_keys (Security §6.2, Agent signing keys §2). The command calls POST /v1/platform/keys/{purpose}/rotate, with ?revoke_previous=true when --revoke-previous is given, using a platform key with platform:ops. It needs no Cloudflare credentials, and no secret is ever read back: the API returns key IDs, never key material.

• One command, two meanings. The first argument decides. thread, link, cursor or web_bot_auth rotates that signing key. An argument starting with key_ rotates an API key, as before (POST /v1/keys/{key_id}/rotate, with --overlap-hours). Anything else is exit 2. --revoke-previous with a key_… argument, and --overlap-hours with a purpose, are exit 2, so a mistyped command never does the other thing.

• web_bot_auth. Its key IDs are 43-character JWK thumbprints, where the other purposes use one character. While PM_WEB_BOT_AUTH is off the API answers 422 web_bot_auth_disabled (exit 7).

• Confirmation. Interactive runs ask first, naming the purpose and how long the previous key keeps verifying: 90 days (thread), 7 days (link), 24 hours (cursor), 7 days in the key directory (web_bot_auth). With --revoke-previous the prompt says what stops working at once: thread tokens fall back to header threading; open download links, console sign-in links, invitations, sessions and OAuth flows under the old link key fail; open search cursors fail with 400; for web_bot_auth, the old key leaves the directory, so signatures made with it fail at verifiers once they fetch the directory again (it may be cached for up to 24 hours). Non-interactive runs need --yes (exit 2 otherwise).

• Output. Human mode:

  Rotated thread key: new kid 4 (2026-10-09T10:00:00Z)
  Previous kid 3 verifies until 2027-01-07T10:00:00Z
  

  With --revoke-previous the second line is Previous kid 3: revoked. A web_bot_auth kid is printed in full. --json prints the response unchanged (purpose, kid, created_at, previous.kid, previous.verify_until, previous.revoked).

• After a suspected leak of a signing key: rotate it with --revoke-previous, then run pmail secrets rotate-master (§12.1), because reading a signing key needs both D1 access and PM_MASTER_KEY.

12.3 Other secrets

PM_CF_API_TOKEN and the SES keys (PM_SES_ACCESS_KEY_ID, PM_SES_SECRET_ACCESS_KEY) rotate with wrangler secret put as listed in Security §6.2; the CLI does not wrap them, and a re-run of setup ses never replaces an existing SES key (§6.9). PM_KEY_PEPPER rotates only through pmail setup --rotate-pepper (§6.5). PM_HASH_KEY is not rotatable in v1.0.

13. dlq

Defined in Observability §8.3. Both commands are calls to the platform API with a platform key holding platform:ops (REST API › Platform operations). The CLI makes no D1 query, Queues API call or Cloudflare call, and needs no Cloudflare credentials: the Worker republishes through its own producer bindings.

• pmail dlq list [--queue <name>] [--status open|redriven] [--tenant <tenant>] [--limit <n>] [--all] calls GET /v1/platform/dlq with the filters queue, status (default open), tenant_id, limit and cursor. Human mode shows ID, queue, kind, tenant, age and redrive count. The API never returns the stored body (inbound pointers carry envelope addresses), so the CLI has nothing to redact. --json prints the response unchanged.
• pmail dlq redrive (<dlq-id>… | --queue <name> [--tenant <tenant>]) [--yes] calls POST /v1/platform/dlq/{dlq_id}/redrive once per item, each with its own generated Idempotency-Key. With --queue, the CLI first lists the open items as list --all does, prints the count and asks for confirmation (non-interactive runs need --yes). One line per item; a failed item is reported and the rest continue. The exit code is that of the first failure, or 0. JSON: { "redriven": [ … items … ], "failed": [ { "id", "error" } ] }. Consumers are idempotent (Design conventions §7), so repeating a redrive is safe.

14. login and config

• pmail login [--profile <name>] asks for the API URL and the key (the key with hidden input), calls GET /v1/me, and on 200 writes the profile named by --profile, default default (§2.2); it prints the key’s level, tenant, identity and permissions. With --key-env NAME or --key-command CMD it stores that source instead of the key. Non-interactive use: --url plus PYLOTA_MAIL_KEY. It warns when PYLOTA_MAIL_KEY will keep overriding the saved key (§2.2).
• pmail config show prints the resolved settings and where each came from (flag, environment, profile), with the key shown as pmk_live_7k2m… (prefix and lookup only).
• pmail config set <key> <value> [--profile <name>] sets url, identity, tenant, account_id, key_env, key_command or default_profile. Setting key this way is refused (it would land in shell history); use pmail login.

15. mcp config

pmail mcp config [--client generic|claude-code|cursor] [--name pylota-mail] prints configuration for the current profile’s URL. It never prints a key; the configuration references an environment variable.

The client formats are documented in the MCP reference. The command also prints which tools the current key would see (GET /v1/me permissions mapped through MCP server §3).

16. webhooks verify

pmail webhooks verify --secret-env WEBHOOK_SECRET (--headers <file> | --id <id> --timestamp <ts> --signature <sig>) [--body <file>] [--tolerance 300] [--now <unix>]

Verifies a captured delivery offline, with the same rules as the receiving guide (Receiving › verifying) and Webhooks design:

1. The secret comes from --secret-env (or --secret, with the process-list warning of §2.2); it must start with whsec_; the rest is standard base64.
2. Headers come from --headers (a file of Name: value lines, case-insensitive names) or the three flags: webhook-id, webhook-timestamp, webhook-signature.
3. The body is read as bytes from --body or stdin, unchanged (no newline added or removed).
4. Content = {webhook-id}.{webhook-timestamp}.{body}; expected = standard base64 of HMAC-SHA256(secret_bytes, content). The signature header is split on spaces; every v1, entry is compared in constant time. Valid when any entry matches.
5. The timestamp must be within --tolerance seconds (default 300) of --now or the clock.

Output: valid (exit 0), or invalid: <reason> (exit 11) where reason is no_matching_signature, timestamp_out_of_tolerance, malformed_secret or missing_header. JSON: { "valid": true, "matched": 1, "event_id": "evt_…" }.

17. ask

pmail ask "<question>" (--identity <id|address> | --tenant <tenant>) [--max-steps 6] [--max-seconds 8] [--include-quarantined] [--no-stream] [--show-trace] [--stream]

1. POST /v1/identities/{id}/search with {"q": question, "mode": "agentic", "budget": {...}, "stream": true} and Accept: text/event-stream (needs search:read and search:agentic). Agentic search is scoped to an identity or a tenant, as the API defines it (REST API › Search): --tenant sends the same body to POST /v1/tenants/{t}/search, which needs a tenant or platform key with the same two permissions and covers up to 100 identities (422 scope_too_large, exit 7, above that); an identity key gets 403 scope_denied (exit 4). search --mode agentic --tenant is the same call without a stream.
2. sse.rs reads events as defined in Search §11.11: lines id:, event:, data:; a blank line ends an event; lines starting with : (keep-alive) are ignored. data is parsed as JSON.
3. Rendering (human mode, terminal):

⋯ step 1  search "claim Golf photos" (hybrid) · 7 hits · 412 ms
⋯ step 2  read thread thr_01JA… · 38 ms

Yes. Admiral accepted claim 7781 on 2 October, after the photos sent on 28 September [1][2].

[1] msg_01JA…  2026-10-02  Admiral Claims <claims@admiral.example>  "Claim 7781 – decision"
[2] msg_01JB…  2026-09-28  Acme Car Hire <compliance@acme.example.com>  "Photos for claim 7781"

answered · confidence 0.86 · 3 steps · 2.8 s

• step events print as dim progress lines on stderr (only when stderr is a terminal, or with --show-trace). evidence events update a counter.
• The answer is printed from the done event, which carries the complete response; citations ([msg_…] markers in answer.text, and sentences[].citations) are renumbered [1], [2] in order of first use and listed with date, sender and subject from evidence. Every string goes through terminal_safe (§3.2).
• insufficient_evidence prints “Not enough evidence to answer.” and the top evidence; budget_exhausted prints the partial answer (if any) marked partial; degraded prints the hybrid results as a search would. All four statuses exit 0; the status is in the last line and in JSON.
• A done event with an error object prints the error as in §3.3 and exits by its code.

4. --json prints only the done event’s data (the same body as the non-streaming call). --json --stream prints each event as one JSON line { "event": "step", "id": 2, "data": {…} } (NDJSON) as it arrives.
5. --no-stream sends stream: false and renders the response the same way.
6. Ctrl-C closes the connection (the server stops at its next state transition) and exits 130.

18. Other client-side behaviour

• search prints a table: date, direction, sender, subject, score and why (first two entries); with --group-by thread one row per thread. degraded: true and semantic_coverage below 0.98 are shown as a warning line. --tenant uses POST /v1/tenants/{id}/search; hits then show the identity. --cursor <cursor> passes a cursor (the next_cursor of the previous page).
• wait prints the message (or timed out), and for --kind verification the code and link on their own lines so a script can read them with --quiet. timed_out: true is exit 13.
• send, reply, reply-all, forward: --text-file and --html-file read bodies; --attach <path> (repeatable) reads files, guesses the content type from the extension (application/octet-stream otherwise) and base64-encodes them; the CLI refuses before sending when the encoded total exceeds 5 MiB unless --allow-large (the tenant may have large_attachments: "link"). Recipients take Name <addr> or addr.
• keys create and webhooks create print the secret once. In human mode it is on its own line after the object, with “shown only once”; --quiet prints only the secret.
• messages raw and messages attachment write bytes to --out <file> (created with mode 0600) or to stdout only when stdout is not a terminal; to a terminal they refuse, so binary or hostile bytes never reach it.
• usage prints the allowances table from GET /v1/usage (feature, granted, used, remaining, resets). A tenant or identity key reads its own workspace and needs no permission (it holds usage:read for its own workspace implicitly); a platform key needs usage:read and a tenant from --tenant or the profile’s tenant, never the default tenant (§2.4): without one the API answers 400 invalid_request (exit 7). usage daily prints one row per day from GET /v1/usage/daily (--from, --to, at most 92 days apart; usage:read, platform or tenant key, with the same tenant rule), including the assertions and http_signatures counts.
• plans list calls GET /v1/plans without an Authorization header, so it works with no key; on a deployment without billing it prints “billing is off”. billing get|set read and change a workspace’s billing account (GET|PATCH /v1/tenants/{t}/billing, platform key with tenants:manage); billing set sends only the flags given (--mode, --plan), and 409 plan_managed_by_stripe is exit 6.
• members list prints members, pending invitations and seats from one call. members invite sends { "email", "role" } (--role defaults to member); with no seat left the API answers 402 billing_limit (seats), exit 8. members remove and invitations revoke take an ID (usr_…, inv_…) or an email address, resolved through members list, and ask for confirmation unless --yes. Removing the owner is 409 owner_required, exit 6.
• jobs start reparse|reembed|reindex sends { "kind", "tenant_id", "identity_ids", "after", "before" }. --tenant is required, and neither the profile’s tenant nor the default tenant replaces it (a job over the wrong tenant is costly to undo); each repeated --identity is resolved to an ID (§2.4); without --identity, identity_ids is null (every identity of the tenant). It prints the job; jobs get <job_id> prints its status and, once it ends, result.
• waitlist invite --count N [--plan P] checks N is 1–500 before sending (exit 2 otherwise) and prints Invited 50; 262 still waiting. from { "invited", "waiting" } (Cloud sign-up §6.1).
• keys create needs --permissions at every level (least privilege is the default, not an option). A platform key has no implicit full set: --level platform without --permissions is exit 2 before any request, with a message listing the permissions a platform key may hold (the API would answer 400 invalid_request). The API also refuses, with 400 invalid_request and details.reason = "permission_not_allowed_for_level" (exit 7), a permission the level cannot hold: identities:sign on a platform key; tenants:manage and platform:ops below platform level; and the tenant-only members:read, members:manage, suppressions:manage, audit:read and usage:read on an identity key. --save-profile <name> writes the new key into that profile.
• Notification preferences have no command: they belong to people, not keys, and are set only in the console (Notifications §2).

18.1 domains add without PM_CF_API_TOKEN

Configuration and Errors (cf_token_required) say that a deployment without PM_CF_API_TOKEN can still add a cloudflare_zone apex with pmail domains add, using the operator’s local token. The API has no request field for registering a domain that a client has already onboarded, so the CLI does it itself, and only when asked with --local-token.

Without --local-token (the default), domains add is a plain API call (§18.2), and the CLI checks nothing locally: the API decides. It maps the two refusals that mean “this deployment is not set up for the method” to exit 3 (config) instead of the API’s exit 7:

• 422 transport_unavailable: the deployment or the tenant’s policy lacks what the method needs. The CLI prints details.reason with its fix (ses_not_configured and ses_receiving_not_configured: pmail setup ses; subdomain_setup_disabled: PM_CF_SUBDOMAIN_SETUP = "on"; zone_creation_not_allowed: the tenant policy domains.allow_create_zone; ses_identity_limit: raise the SES limit; method_not_supported: another method).
• 422 cf_token_required: the deployment has no PM_CF_API_TOKEN. The fix is “set PM_CF_API_TOKEN on the deployment (wrangler secret put PM_CF_API_TOKEN), or, for a zone apex, run again with --local-token”.

The CLI never falls back to the local token on its own.

With --local-token:

1. Prerequisites, checked locally before any request. --method cloudflare_zone (any other method is exit 2: nameservers and delegated_subdomain need zones that the Worker must create and watch); CLOUDFLARE_API_TOKEN and the account ID of §2.5 (exit 3); the domain is a zone apex in that account, found as in setup’s preflight step 4 (a subdomain is exit 2 with the fix “set PM_CF_API_TOKEN on the deployment”: its literal routing rules are created per address over the domain’s life, including retries and retirements, which a one-off CLI run cannot own).
2. Call POST /v1/tenants/{t}/domains as usual, so the key’s permission (domains:write), the tenant and the domain name are checked by the API. If the deployment does have PM_CF_API_TOKEN, the Worker onboards the domain and the result is printed as usual; the local token is not used. Anything other than 422 cf_token_required is handled as usual.
3. On cf_token_required: run steps 1–8 of Identities, addresses and domains › Kind zone with the local token (including the existing-MX and SPF preflights, with --replace-mx as the explicit opt-in).
4. Insert the row through the D1 query API (POST /accounts/{a}/d1/database/{id}/query), with the account ID of step 1: the database is the one named pylota-mail in that account, found by name as in setup step 2, or the database_id of <dir>/wrangler.toml when that file exists. The statement is the one of §6.6 with tenant_id, kind = 'zone', method = 'cloudflare_zone', inbound = 'routing' and state = 'pending'. The Worker’s cron hook mints the monitor, starts verification and emits domain.created. An apex uses the catch-all, so no literal rules are needed.
5. Steps the Cloudflare API cannot do (spike S9) are printed as dashboard steps, and doctor checks them.

A Cloudflare API or D1 failure in steps 3 and 4 is exit 10; every step reads first, so a re-run continues.

18.2 domains add --method

pmail domains add <name> --method <method> [flags] builds the create body of Domains on any DNS host §8 from its flags and calls POST /v1/tenants/{t}/domains (domains:write). --method is required; the CLI never sends the old kind spelling.

• A flag that the chosen method does not allow, or a missing required one, is exit 2 before any request. --smtp-port other than 465 or 587 is exit 2 too (the API would answer 400 smtp_port_not_allowed).
• The SMTP password is never accepted on the command line, from the environment or from the config file. --smtp-password-stdin reads it from stdin up to the first newline (removed); when stdin is a terminal the CLI asks with hidden input. The value is held in memory for the one request and is never printed, logged or included in an error document.
• Output. The domain in pending, then its records as a table with both name (fully qualified) and host (relative to the registrable domain), so the user can enter whichever their DNS host wants (N17); columns type, name, host, value, priority, purpose, required. For nameservers and delegated_subdomain the records are the NS values to set at the registrar or DNS host. --json prints the response unchanged.
• Errors keep their API meaning: 409 domain_not_dedicated (exit 6) prints details.records and the fix --confirm-dedicated; 429 upstream_rate_limited (exit 8) prints the retry time. 422 transport_unavailable and 422 cf_token_required are the two exceptions to the API’s exit code: exit 3, with the fixes listed in §18.1.

18.3 domains update, domains probe and addresses test-forwarding

• domains update <domain> sends PATCH /v1/domains/{domain_id} (domains:write). --transport cloudflare|ses sets transport, which only a platform key may change (403 scope_denied, exit 4, for others). The --smtp-host, --smtp-port, --smtp-username, --smtp-password-stdin and --probe-from flags send a complete smtp object, as on domain create: the CLI reads the domain first and fills host, port, username and probe_from that were not given from its current smtp. The API never returns the password, so --smtp-password-stdin is required with any --smtp-… or --probe-from change (exit 2 otherwise), with the stdin rule of §18.2. The API keeps new smtp values pending until a probe passes and answers 200 with the domain; the CLI prints it and says the probe is running.
• domains probe <domain> sends POST /v1/domains/{domain_id}/probe (domains:write) and prints the probe_id from the 202. The result arrives as a domain health change, so the CLI points to pmail domains health <domain>. More than one probe a minute is 429 rate_limited (exit 8).
• addresses test-forwarding <address> sends POST /v1/identities/{identity_id}/addresses/{address_id}/test-forwarding (identities:write). The argument is an address ID (with --identity) or the address itself, resolved through GET /v1/identities/lookup and the identity’s address list. It prints that the test was sent; the result appears within 10 minutes as the address’s forwarding (ok or failed) in pmail addresses list. A domain without inbound: forward gives 422 transport_unavailable (method_not_supported), exit 7.

18.4 domains subscribe

pmail domains subscribe <domain> [--tenant <tenant>] exists for the spike S9 fallback (Identities, addresses and domains › Kind zone): a Cloudflare-transport domain created without an Email Sending event subscription reports delivery_events: "manual" and details.action = "run pmail domains subscribe <domain>". Delivery events for that domain start once this command has run.

1. GET /v1/domains/{domain_id} (resolved by name as in §2.4). Anything other than transport = "cloudflare", sending = true and delivery_events = "manual" prints the current value and exits 0 without changes (a re-run is a no-op).
2. With the operator’s local CLOUDFLARE_API_TOKEN (exit 3 without it): find the zone ID by name (GET /zones?name=), then run wrangler queues subscription create pm-delivery-events --source email.sending --zone-id <zone_id> --domain <domain> (the flags read from the Wrangler 4 command reference on 2026-10-09). Before creating, list the subscriptions (GET /accounts/{a}/event_subscriptions/subscriptions) and reuse one that already targets this zone and domain, so an interrupted run never makes two.
3. Record the ID through the D1 query API, with the account ID and database found as in §18.1 step 4: UPDATE domains SET event_subscription_id = ?1 WHERE id = ?2 AND event_subscription_id IS NULL. The domain then reports delivery_events: "active".
4. Print the domain. --json prints it unchanged. Wrangler or Cloudflare API failures are exit 10.

pmail doctor (sending.event_subscriptions) fails for every manual domain, with this command as the fix.

18.5 identity-keys, assertions and http-sign

The client side of Agent signing keys. Every command except assertions verify takes --identity (resolved as in §2.4); an identity key uses its own identity. Key management works while the identity is paused (Agent signing keys §2); a deleting or deleted identity is 404 identity_not_found (exit 5). No private key ever reaches the CLI.

identity-keys (identities:read to list, identities:write for the rest; platform, tenant or identity key):

• pmail identity-keys list --identity <identity> [--status active|retiring|retired] [--limit <n>] [--all] calls GET /v1/identities/{id}/keys. Human mode prints a table of kid, status, created_at, verify_until and retired_at, newest first, retired keys included. The public JWKs are in the JSON output only.
• pmail identity-keys create --identity <identity> calls POST /v1/identities/{id}/keys with {}. 201 prints Created key <kid>; 200 prints Active key <kid> already exists and changes nothing. Both exit 0. Keys are also created on the first signing request, so this command is optional.
• pmail identity-keys rotate --identity <identity> calls POST …/keys/rotate and prints the new kid and, when there was one, the previous kid with its verify_until. It asks no confirmation: the previous key keeps verifying through the overlap (PM_IDENTITY_KEY_OVERLAP_DAYS, default 7 days).
• pmail identity-keys revoke <kid> --identity <identity> [--yes] calls POST …/keys/{kid}/revoke. Interactive runs ask first, saying that assertions signed with that key stop verifying at once, as soon as verifiers fetch the JWKS again (it is cached for up to 5 minutes); non-interactive runs need --yes (exit 2 otherwise). An unknown kid is 404 key_not_found (exit 5); a key already retired prints already retired and exits 0.

assertions create (identities:sign, tenant or identity key; a platform key cannot hold the permission and is refused with 403, exit 4):

pmail assertions create --identity <identity> --audience <aud> [--expires-in <60-600>] [--nonce <nonce>] [--ext <json> | --ext-file <file>]

• Sends POST /v1/identities/{id}/assertions with audience, expires_in (default 300), nonce and ext. --ext must parse as a JSON object (exit 2 otherwise); the size and claim-name rules are the API’s (400 invalid_request, exit 7). No Idempotency-Key is sent (§4).
• Output: the response as indented JSON (assertion, kid, expires_at, jwks_uri); --quiet prints only the token, for $(…) in a script. The token is a short-lived credential for its audience: the CLI never writes it to a file or a log.
• A paused identity, or one of a suspended tenant, is 409 identity_paused (exit 6).

assertions verify (no API key and no Cloudflare credentials):

pmail assertions verify <token> --audience <aud> [--issuer <url>] [--now <unix-seconds>]

Checks an assertion offline, the way a verifier should, by calling the SDK’s verify_assertion (Rust workspace §11), which follows Agent signing keys §4.3:

1. The token comes from the argument, or from stdin when it is - (a token on the command line is visible in the process list, as in §2.2).
2. --audience is required (exit 2 without it). --issuer defaults to the resolved API URL (--url, PYLOTA_MAIL_URL or the profile’s url); with none of them, exit 3. It must be https:// except for localhost, 127.0.0.1 and [::1] (exit 2 otherwise).
3. The header must have alg: EdDSA and typ: agent-assertion+jwt; iss must equal the issuer. Only then is {iss}/.well-known/jwks/{sub}.json fetched, without an Authorization header and after checking that sub is a well-formed identity ID. A key URL inside the token is never used.
4. The key whose kid matches verifies the Ed25519 signature; aud must equal --audience; nbf and exp are checked against --now or the clock, allowing 60 seconds of skew.
5. Replay (step 6 of §4.3) needs state across calls, so the CLI does not check it; it prints jti and exp for a caller that keeps a replay cache.

Output: valid and the claims (sub, email, name, org, aud, exp, jti, kid), exit 0; or invalid: <reason>, exit 11 (verification, §3.4), where reason is malformed, unsupported_algorithm, issuer_mismatch, identity_not_found (the JWKS answered 404: the identity is unknown, paused, suspended or deleted), unknown_kid, bad_signature, audience_mismatch, expired or not_yet_valid. A JWKS fetch that fails for another reason (network, TLS, 5xx) is exit 9, not a verdict. JSON: { "valid": true, "kid", "claims": { … } } or { "valid": false, "reason" }.

http-sign (identities:sign, tenant or identity key):

pmail http-sign --identity <identity> --url <https-url> [--method <METHOD>] [--expires-in <30-300>] [--component @method|@path|@query]…

• Sends POST /v1/identities/{id}/http-signatures with url, method, expires_in (default 60) and, when --component is given, components: @authority, signature-agent and from (always signed) plus the repeated --component values. --method is signed only with --component @method, as the API defines it. Other component names are exit 2 before the request. No Idempotency-Key is sent.
• Human and quiet modes print the four headers as Name: value lines, in the order Signature-Agent, From, Signature-Input, Signature, ready for curl -H @file; --json prints the response unchanged (headers, expires_at). The signature expires after --expires-in seconds, so it is made right before the request it signs.
• Errors keep their API meaning: 422 web_bot_auth_disabled (exit 7) while PM_WEB_BOT_AUTH is off; 403 policy_denied (exit 4) while the tenant policy web_bot_auth.allowed is false; 400 invalid_request (exit 7) for a URL that is not https, an expiry outside 30–300 s or a non-ASCII component value; 409 identity_paused (exit 6).

Signing by both commands shares the RL_SIGN limit of 600 calls a minute per identity; over it the API answers 429 rate_limited (exit 8, after the retries of §4).

19. Command-to-endpoint map

This is the command tree: every pmail command and what it calls. A command needs the permission of its endpoint (REST API); the rows for platform operations, members, billing, the newer domain commands and the signing commands name it. Notification preferences have no command: they are set only in the console (Notifications §2).

Tests
