Inline comments:
In `@docs/guides/aws-signers/.env.example`:
- Around line 34-36: Reword the cursor signing key note in the .env.example
guidance so it does not claim the prod stage itself refuses to start; the
enforcement happens through Compose variable expansion in the docker-compose
setup. Update the comment near the pagination cursor secret description to match
this behavior, keeping the requirement for a 32-byte hex key but removing any
runtime-startup wording tied to prod.
In `@docs/guides/aws-signers/README.md`:
- Around line 65-67: The README wording for GUARDIAN_DASHBOARD_CURSOR_SECRET
should be updated because the current phrasing incorrectly implies the server
itself enforces the startup failure. Rephrase the explanation in the aws-signers
guide to make it clear that the immediate check happens in the Compose
required-variable validation driven by GUARDIAN_ENV=prod, and that this is what
blocks startup when the secret is missing.
In `@docs/guides/production/docker-compose.yml`:
- Line 24: The docker-compose service is publishing the metrics port externally
via the 9464 mapping, which exposes the endpoint on all interfaces by default.
Update the compose configuration for the affected service entries to bind
metrics to loopback only or remove the published port entirely, and keep the
change consistent across all referenced instances in the docker-compose file.
- Around line 19-20: The production docker compose service is defaulting to an
unstable image tag via the image field that references GUARDIAN_VERSION with a
latest fallback, which can cause non-reproducible deployments. Update the
compose configuration to require an explicit version tag for the guardian image
and remove the latest default from the image reference in the docker-compose
setup, keeping the change localized to the service definition that uses
pull_policy.
In `@docs/superpowers/specs/2026-06-24-production-guide-design.md`:
- Around line 17-25: The spec currently states an AWS-only scope and explicitly
says there is no committed Compose track, which conflicts with the new Docker
Compose deliverables. Update the scope/non-goals text in the production guide
spec to match the implemented `docs/guides/production/docker-compose.yml` and
related README content, using the existing “Scope” section and any references to
`PRODUCTION.md`/Compose so acceptance criteria are consistent.

🚀 New features to boost your workflow:
|
- Attribute cursor-secret enforcement to the Compose ${VAR:?} expansion rather
than a server-side prod guard (the server cursor secret is optional on main;
the hard requirement lands with #301).
- Production compose: require an explicit GUARDIAN_VERSION (drop the :latest
default) and bind the metrics port to loopback (127.0.0.1:9464).
- Track B smoke: drop the unconfirmed "storage encryption" log grep; rely on
ECDSA-signer-ready + clean startup.
- Remove the design-spec artifact from the PR (brainstorming doc, not repo
content).

so any write failure removes the newly created output file before returning the
existing error. Preserve the current error message and successful-write
behavior.
In `@crates/server/src/builder/storage.rs`:
- Line 202: Update StorageKeySource variants and their constructors to store
direct and related encryption keys as SecretString immediately, using the secret
wrapper from src/secret/ and reading-and-wrapping in one expression. Keep
plaintext exposure limited to from_dev_key when parsing the value, and adjust
load() and all affected match arms to access the wrapped secret only where
required.

restarting the server after the update.

LGTM, minor comments:
-
smoke.shcan't run against a locally built image.docker-compose.ymlpinspull_policy: always, soupaborts withmanifest unknownfor any tag not on GHCR. Since the guides README calls this script the CI-job candidate, it should accept a pull-policy override (e.g.SMOKE_PULL_POLICY=missingapplied to the scratch copy). -
Every client defaults to Falcon, so A4/B6's "run the SDK smoke path" fails against the templates'
ecdsa-only gate. The demo,smoke-web, andexamples/rustall default to Falcon, andexamples/rusthas no ECDSA option at all. Add a line to A4 and B6 to select ECDSA, and file a follow-up for an ECDSA path inexamples/rust.

Closes #299.
Two things ship together here: the end-to-end production guide, and the server changes that make its no-AWS track simple enough to follow by hand.
Production guide (
docs/guides/production/)Three tracks to the same hardened shape, each with committed, runnable artifacts:
scripts/aws-deploy.sh+ Terraform.env.aws-ecs.exampledocker-compose.yml,.env.example,operators.example.json,smoke.shdocker-compose.aws-no-ecs.yml,.env.aws-no-ecs.exampleTrack A, the reference deployment, is the recommendation. Track C is for operators who cannot run ECS at all: it keeps secret custody in Secrets Manager and KMS on any Docker host, because Guardian's custody, hosted ECDSA signer, and runbooks are built around AWS today.
smoke.shruns track B end to end with no AWS credentials and no Rust toolchain (identity comes from the image), asserts the prod-stage guards, the prod runtime defaults, metrics gating, and identity stability across restart, and tears down. Track B was also followed by hand from the README, B1 through B6, against a locally built image.PRODUCTION.md,CONFIGURATION.md,TROUBLESHOOTING.md,runbooks/secrets.md,SERVER_AWS_DEPLOY.md,infra/README.md, andspec/api.mdare updated to match.Server changes
ack-keygenships in the image (/app/ack-keygen) and gains--out-dir: writes both ACK key files as0600, refuses to overwrite an existing identity, cleans up if the second write fails. Stdout JSON mode is unchanged (used byaws-deploy.sh).GUARDIAN_ENV=prodapplies the production runtime defaults inside the server viaconfig::stage::Stage: rate limits 200/5000, DB pools 32, canonicalization concurrency 50,jsonlogs. Explicit variables always win;GUARDIAN_MAX_REPLICASis deliberately excluded (topology, not stage). Terraform still injects every value explicitly, so ECS stacks are unaffected. Deployments that setGUARDIAN_ENV=prodwithout those variables (for example the aws-signers guide) pick the new values up on upgrade; upgrade notes added.GUARDIAN_STORAGE_ENCRYPTION_KEY_FILE: the same{active, keys}key document Secrets Manager holds, read from an owner-only file, so self-managed deployments get multi-key rotation. Exactly one key source may be configured.GUARDIAN_ALLOWED_ACCOUNT_SCHEMES(falcon,ecdsa; unset or blank = both): a registration-only gate inconfigure_account. Accounts already in this Guardian's metadata are never affected. Recommendedecdsaon the AWS tracks because only ECDSA has a hosted signer (KMS); the Falcon ACK key stays required at startup either way.

The Rust client reads codes and meta generically and needed no change.Release pin (read before merging)
v0.17.0is already published and has none of these server changes. An older image does not reject the new variables: it boots, stores payloads in plaintext, accepts every scheme, and runs the development rate limits. The templates therefore leaveGUARDIAN_VERSIONblank so Compose refuses to start until a tag is chosen,smoke.shrequires one, and the guide says "later than v0.17.0" and names the banner tell (account_schemeson theack signersline). Once the release containing this PR is tagged, set that tag in.env.example,.env.aws-no-ecs.example, and the README's<version>placeholders.Not in scope
Making the Falcon ACK signer optional, and the dashboard's Falcon-only operator login. Both are separate decisions.
