Why

Local development of this repo currently authenticates against the production Zitadel. .env.local.example:70 points AUTH_ZITADEL_ISSUER at auth.catholicdigitalcommons.org, and sign-in relies on a http://localhost:3000 redirect URI registered on that production instance.

cdcf-infra #20 removes that localhost client, per the convention settled in CatholicOS/martyrology-api#26 (local development runs against a local Zitadel, which is why LitCal and Martyrology have no such client).

It cannot be removed first. Auth.js v5 is live here — next-auth 5.0.0-beta.31, lib/auth.ts, app/api/auth/[...nextauth], app/api/auth/zitadel-signout — so that client is in active use. Dropping it without a replacement would delete local sign-in rather than relocate it. This design is the replacement, and #20 waits on it.

What this PR contains

A design document only — docs/superpowers/specs/2026-08-17-local-zitadel-stack-design.md. No compose or env changes yet; status is design, pending implementation plan.

It specifies adding zitadel-db + zitadel services to the compose stack, provisioned by the existing cdcf-infra/auth/setup-zitadel.sh --target local, and making the local instance the default for development rather than an opt-in — if .env.local.example keeps pointing at production, the production origin can never be retired.

Two decisions carry their reasoning:

  • Zitadel gets its own postgres:16-alpine rather than reusing db, which is mariadb:11. This is the single place the martyrology-api template cannot be copied.
  • The port defaults to 8090, not 8080. martyrology-api already defaults its local Zitadel to 127.0.0.1:8080; a third stack there means only one can run at a time, and the collision surfaces as an opaque bind failure.

The image is pinned to ghcr.io/zitadel/zitadel:v4.15.0, matching martyrology-api. The older docs/zitadel-oidc-plan.md says :latest, which is wrong for a stack whose management API is called by versioned path — a silent major bump would break provisioning with no change in this repo.

Ordering

This lands first, then cdcf-infra #20. Until #20 lands, a local provisioning run registers the production origin set — harmless inside a local instance, but not yet correct. Removing the localhost:3000 client from the production Zitadel is #20's step, and happens only after developers are verified onto this stack.

Verification

Reviewed against the repo and against cdcf-infra main. Confirmed accurate: the .env.local.example issuer line, the Auth.js surface, db being mariadb:11, AUTH_ZITADEL_ORG_ID consumed at lib/auth.ts:69, .zitadel-data/ already gitignored, every docs/zitadel-oidc-plan.md section reference in §6, martyrology-api's v4.15.0 pin and 8080 default, port 8090 being free, and — on cdcf-infra main — that --target, --provision-cdcf-website and the exit-13 guard all exist today, so the §4 command runs without waiting for #20.

One correction was made during review (64f81bc): §3.2 described the stray root zitadel/ directory as empty and historyless. It holds an empty, root-owned nginx.conf/ directory, so removal needs elevated privileges; and zitadel/nginx.conf existed as a real file on the unmerged feature/zitadel-integration branch, untouched by this deletion.

§7 documents a manual verification sequence rather than an automated one, and says so plainly — an automated check would need a full browser OIDC round-trip in CI. Step 7, confirming nothing in the flow reaches the production issuer, is the one that actually proves the goal.

One claim could not be verified: that LiturgicalCalendarFrontend also defaults its local Zitadel to 8080. That repo is not cloned locally. It does not affect the decision — the verified martyrology-api collision is sufficient on its own.

Prerequisite for cdcf-infra #20, which removes the http://localhost:3000
client currently registered in the PRODUCTION Zitadel. That client is not
vestigial: Auth.js v5 is live here and .env.local.example points local dev at
auth.catholicdigitalcommons.org, so removing it first would delete local
sign-in rather than relocate it. This stack is the replacement; #20 waits on it.

Two decisions worth their reasons:

Zitadel gets its own postgres:16-alpine rather than reusing `db`, because `db`
is mariadb:11 and Zitadel requires PostgreSQL. This is the one place
martyrology-api's stack cannot be copied.

The port defaults to 8090, not 8080. martyrology-api and
LiturgicalCalendarFrontend both default their local Zitadel to 8080, so a third
stack there means only one runs at a time, and the collision surfaces as an
opaque bind failure.

The image is pinned to v4.15.0 rather than the existing plan doc's :latest,
because cdcf-infra's setup-zitadel.sh calls the management API by versioned
path; a silent major bump would break provisioning with no change in this repo.

Also records that docs/zitadel-oidc-plan.md has gone stale in a way that is
actively dangerous: its Production Deployment section instructs standing up
Zitadel at auth.catholicdigitalcommons.org, an instance that already exists and
is managed by cdcf-infra. Following it would create a second production IdP.
Its Phase 2 Auth.js work is already done; the WordPress OIDC and passkey phases
are genuinely undone and stay deferred.

Review of the design against the repo found one inaccurate sentence. The
directory is not empty: it holds an empty, root-owned nginx.conf/ directory,
a bind-mount artifact from a compose file that once referenced a file there.
Root ownership means removal needs elevated privileges, which the
implementation would otherwise discover the hard way.

"Has no history" was also too strong. It is true of main, but
zitadel/nginx.conf existed as a real file on feature/zitadel-integration
(9d20fac, 066003d), which still exists on origin and is untouched by this
deletion.

Every other claim in the document verified against the repo and against
cdcf-infra main.

📝 Walkthrough

Walkthrough

The PR adds a local Zitadel development stack with PostgreSQL, Login V2, an nginx proxy, PAT provisioning, local OIDC settings, Compose validation, setup guidance, and updated authentication plans.

Changes

Local Zitadel Authentication Stack

Layer / File(s) Summary
Local stack and authentication target
docker-compose.yml, nginx/zitadel.conf, docs/superpowers/specs/...
The stack adds PostgreSQL storage, pinned Zitadel services, Login V2, proxy routing, persistence, health checks, local ports, and PAT initialization.
Provisioning and application configuration
.env.local.example, README.md, AGENTS.md, docs/superpowers/plans/..., docs/superpowers/specs/...
The project uses local issuer and organization settings and documents PAT-based provisioning, credentials, port coordination, recovery, and required environment variables.
Compose checks and CI wiring
scripts/tests/zitadel_compose.bats, .github/workflows/test-worker.yml
Bats tests validate Compose services, ports, PAT settings, environment examples, and README URLs. CI now runs for Compose changes.
Verification and OIDC plan updates
docs/superpowers/specs/..., docs/superpowers/plans/..., docs/zitadel-oidc-plan.md
The documents define manual local sign-in checks, mark completed or superseded work, and record deferred authentication tasks.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to 2cd2a

The PR introduces the local authentication stack, but startup can report success before the login service is usable, causing local sign-in to fail immediately after launch. The plan also contains an incorrect proxy-port reference and a minor environment-variable documentation error, so merge should wait for the readiness behavior and documentation to be corrected or explicitly accepted.

secret, passes that value to the command, and reuses the same key across
restarts and existing data.
- Around line 28-30: Expand the zitadel-db design section to define the complete
v4.15.0 PostgreSQL connection contract for the zitadel service: host, port,
database, user, password source, and disabled SSL mode. Specify whether the
configuration uses ZITADEL_DATABASE_POSTGRES_DSN or equivalent settings, and
include verification that migrations succeed with a fresh named volume.
- Around line 32-36: Update the Zitadel stack specification to explicitly choose
a login version: either add the v4.15.0 zitadel-login service, route
/ui/v2/login to it, and define the login-client.pat bootstrap contract, or
disable Login V2 before initialization and verify the OIDC authorize flow uses
Login V1.

The lint workflow's prettier --check step failed on this file, and all 7
Codacy findings were the same defect reported separately: "Table pipe does
not align with header" on the §6 table rows.

npm run format:md pads the §6 table cells so every row shares the same pipe
positions, and normalises one *emphasis* to _emphasis_. Both CI steps now
pass locally: format:md:check reports all files formatted, lint:md reports
0 errors over 24 files.

Review found §3.2 labelled "the load-bearing configuration" while omitting
settings the stack cannot start without. Checked against martyrology-api,
which this design names as its template and which already carries all of
them.

Added, with the failure each one prevents:

- masterkey with a value. `start-from-init --masterkey` had no argument.
  It must be exactly 32 characters and must never change, since Zitadel
  cannot decrypt instance data after a rotation.
- The full ZITADEL_DATABASE_POSTGRES_* set, pointed at §3.1's zitadel-db
  rather than the mariadb `db`. Both SSL modes are `disable`; without them
  Zitadel attempts TLS against a non-TLS Postgres and dies during migration.
- LOGINV2_REQUIRED: false. With no zitadel-login container the authorize
  flow would land on an unserved route. Disabling V2 rather than adding the
  container follows the umbrella convention that each property builds its
  own sign-in UI.
- The three FIRSTINSTANCE_ORG_MACHINE_* settings. PATPATH alone names a file
  nothing writes, so the PAT that §4 calls "the entire integration" would
  never exist.
- user: "0" and the /app/zitadel ready healthcheck.

Also resolved a doc-internal inconsistency: §3.2 used ${ZITADEL_PORT:-8090}
while §4 and §5 hardcoded 8090 in three further places, so overriding the
port silently pointed provisioning and Next.js at nothing. Documented as one
value restated four times. Noted that setup-zitadel.sh defaults
ZITADEL_INTERNAL_URL to 8080 for every target, so it must be set explicitly,
and that Compose reads ZITADEL_MASTERKEY / ZITADEL_DB_PASSWORD from .env
rather than .env.local.

Addresses CodeRabbit findings on lines 30, 36 and 45 of PR #286.

Implements docs/superpowers/specs/2026-08-17-local-zitadel-stack-design.md in
three tasks: compose services, flipping local dev onto them, and correcting the
stale OIDC plan doc.

One deliberate departure from the spec. §7 argues verification must be manual
because an automated check would need a browser OIDC round-trip. That holds for
the flow, and the plan keeps it manual. It does not hold for the configuration:
`docker compose config` resolves interpolation without starting a container, so
the image pin, SSL modes, machine-user block and — most importantly — the port
derivation are cheaply testable. The spec itself flags that one port is restated
in four places with nothing validating their agreement, so the plan adds bats
cases that read the port out of the resolved config and require the compose
mapping, ZITADEL_EXTERNALPORT and .env.local.example to agree, including under a
ZITADEL_PORT override. Leaving that untested was the wrong call.

docker-compose.yml joins test-worker.yml's path filters so those cases gate the
file they cover rather than only firing when a test changes.

Local development authenticates against the production Zitadel today, via a
localhost:3000 client registered there. This is the replacement that lets
cdcf-infra #20 remove that client.

Its own postgres:16-alpine rather than the stack's db, which is mariadb:11 and
cannot host Zitadel. Port defaults to 8090 because martyrology-api and
LiturgicalCalendarFrontend both use 8080, and a third stack there means only
one runs at a time.

The bats cases pin what nothing else validates: that the published port and
ZITADEL_EXTERNALPORT stay equal under a ZITADEL_PORT override, since a
mismatch mints issuer URLs that look correct and do not resolve.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Flips AUTH_ZITADEL_ISSUER from the production instance to localhost:8090 and
adds AUTH_ZITADEL_ORG_ID, which lib/auth.ts already reads but no example
documented.

Defaulting rather than documenting an opt-in is the point: while the example
points at production, developers keep using the localhost:3000 client
registered there, and cdcf-infra #20 can never remove it.

The new bats case reads the port out of the resolved compose config and
requires the env example to agree, so the two cannot drift.
Its Production Deployment section instructed standing up Zitadel at
auth.catholicdigitalcommons.org. That instance exists and is managed by
cdcf-infra, so following the section would have created a second production
identity provider.

Also marks Phase 2.1-2.3 done (Auth.js v5 shipped), and §1.1/§1.3 superseded by
the local stack design and by automated provisioning. The WordPress OIDC and
bearer-validation phases are genuinely outstanding and are left as they are.
- README.md: scope masterkey-rotation recovery to zitadel/zitadel-db and
  their db volume instead of `docker compose down -v`, which would also
  wipe db_data/redis_data/wordpress_data.
- AGENTS.md: qualify AUTH_ZITADEL_ISSUER as prod-vs-local and add the
  missing AUTH_ZITADEL_ORG_ID to the canonical env-var reference, so this
  doc no longer contradicts .env.local.example for local development.
- docs/zitadel-oidc-plan.md: replace §1.3's manual console walkthrough
  (still citing port 8085) with a pointer to cdcf-infra's automated
  setup-zitadel.sh flow, and correct the Verification Steps curl target
  from 8085 to 8090.
- scripts/tests/zitadel_compose.bats: cover the previously-unguarded port
  restatements in README.md and the .env.local.example comment block, and
  make the "no production issuer" case assert the file exists so a
  missing/renamed file fails loudly instead of passing by accident.

Four of the five findings verified as still valid against the current tree;
one was already handled and is skipped.

Fixed:

- ZITADEL_DB_PASSWORD is write-once, same as the masterkey but for a
  different reason: POSTGRES_PASSWORD initialises the Postgres role only on
  an empty volume, so changing it once zitadel_db_data exists leaves the role
  on its old password while the variable reads as correct. Documented with
  the recovery sequence in the README, and in the spec's and plan's gotcha
  lists.
- README now uses `docker compose up -d --wait`. Both services define
  healthchecks, so without --wait the command returns mid-migration and the
  provisioning run fails on a PAT that does not exist yet.
- The volume-removal block lists volumes before removing one, and no longer
  hands the reader a literal cdcf-website_zitadel_db_data to paste — the
  prefix is the Compose project name and differs when overridden.
- Added a verification step proving local sign-in actually left production:
  read the resolved issuer from /api/auth/providers, then watch the network
  tab across sign-in and /api/auth/zitadel-signout for any request to the
  production host. Every other step can pass while still using production.
- Corrected a real contradiction with AGENTS.md: the plan's status banner
  called §2.4 (WordPress bearer validation) deferred, but it shipped as
  includes/auth/zitadel-bearer.php, is loaded from functions.php:723 and has
  ZitadelBearerTest.php. Marked done, with §2.4's body flagged stale and
  AGENTS.md named authoritative.

Skipped:

- Removing the obsolete executable instructions from zitadel-oidc-plan.md.
  Those sections already carry superseded banners (§1.1, §1.3, Phase 2,
  Production Deployment), and the design settled on correcting that document
  where it misleads rather than rewriting it. The banners are the quarantine;
  deleting the content would lose the record of the original intent.

Validated: prettier and markdownlint clean over 25 files, `docker compose
config` valid, both healthchecks present, all 14 zitadel_compose.bats pass.

Reverses the Login V1 decision on this branch. Production serves Login V2 —
cdcf-infra auth/docker-compose.prod.yml runs ghcr.io/zitadel/zitadel-login
with LOGINV2_REQUIRED 'true' — so a local stack on V1 exercised a sign-in UI
no deployed environment serves, and any V2-specific bug would first appear
after deploy. The earlier rationale here was wrong on the facts.

The zitadel-login container is interim. cdcf-infra deliberately does not own
a login UI on each property's behalf; the intended end state is each property
implementing sign-in natively against the Zitadel APIs, at which point this
service is dropped. Until cdcf-website does that, it runs what production runs.

Compose gains two services and loses a published port:

- zitadel-login, version-pinned to the backend (mixing versions is
  unsupported upstream), consuming a SECOND first-instance PAT
  (login-client.pat) minted by the new ZITADEL_FIRSTINSTANCE_ORG_LOGINCLIENT_*
  block. The flag alone is not enough: without the container the authorize
  flow redirects to /ui/v2/login and nothing answers. EMAIL_VERIFICATION
  matches production, without which signups land ACTIVE with an unverified
  email and no mail queued.
- zitadel-proxy (nginx, nginx/zitadel.conf) owning ${ZITADEL_PORT:-8090} and
  routing /ui/v2/login* to the UI, everything else to the backend, so both
  share one origin as they do in production. zitadel now publishes no port.

Two local-only bugs found by running it, neither reproducible in production:

- nginx $host strips the port, so Zitadel advertised `issuer:
  http://localhost` and Auth.js refused sign-in with "issuer property does
  not match the expected value". Both Host AND X-Forwarded-Host need
  $http_host — X-Forwarded-Host wins, so fixing Host alone still fails.
  Production is unaffected because it serves on 443.
- The proxy healthcheck used localhost, which resolves to ::1 first while
  nginx listens IPv4-only, so a healthy proxy reported unhealthy and --wait
  failed. Pinned to 127.0.0.1.

Verified end to end on a clean volume: both PATs written on first boot, all
seven services healthy, discovery reports issuer http://localhost:8090, and
sign-in redirects to /ui/v2/login/login?authRequest=V2_… carrying the CDCF
organization id. 18/18 bats pass.

Spec §3.2 is corrected and gains §3.3 for the two new services; the plan's
constraints are updated and its pre-Login-V2 snippets flagged; the README
documents the four services and the interim status of the login container.

Wait for Login V2 readiness before starting the proxy.

Add the upstream Login V2 healthcheck for /ui/v2/login/healthy, and change the proxy dependency to service_healthy. Otherwise, docker compose up --wait can report readiness while Login V2 is still unavailable.

zitadel-proxy’s zitadel-login dependency condition from service_started to

**Architecture:** Four new Compose services — `zitadel-db` (its own PostgreSQL, because the stack's `db` is MariaDB), `zitadel`, `zitadel-login` (the v2 sign-in UI production also runs) and `zitadel-proxy` (nginx, giving all of it one origin on `${ZITADEL_PORT:-8090}`) — with Zitadel writing two first-instance PATs into a bind-mounted `./.zitadel-data/`: `automation-user.pat` for provisioning and `login-client.pat` for the login UI. A host-run `cdcf-infra/auth/setup-zitadel.sh --target local` reads the former and provisions the CDCF app. No provisioning script is added to this repo.

> **Amendment (post-implementation):** this plan was written for a two-service, Login V1 stack. Login V2 was added afterwards to match production, which turned it into four services and moved the published port from `zitadel` to `zitadel-proxy`. The Global Constraints below are current; the literal compose and bats snippets inside Task 1 and Task 2 are **not** — they predate the change. Read `docs/superpowers/specs/2026-08-17-local-zitadel-stack-design.md` §3.2–§3.3 and the committed `docker-compose.yml` / `scripts/tests/zitadel_compose.bats` for the shipped shape.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Correct the current proxy port constraint.

The amendment says the Global Constraints are current. However, the constraint still specifies 127.0.0.1:${ZITADEL_PORT:-8090}:8080. zitadel-proxy publishes port 80; port 8080 is only the backend port.

Proposed fix
-- Published port: `127.0.0.1:${ZITADEL_PORT:-8090}:8080`.

`next dev` writes a managed block into AGENTS.md on every start
(node_modules/next/dist/server/lib/generate-agent-files.js). It opens with its
own H1, so MD025/single-title fired in a file that already has one and
`npm run lint:md` failed on any tree where the dev server had run — reported
three times, since CLAUDE.md and GEMINI.md are symlinks to AGENTS.md. Deleting
the block only recreated the dirty diff, so the block is now committed.

MD025 is disabled from an inline directive above the block rather than turned
off in .markdownlint.yml, so the rule still protects every other document.
Placement is deliberate and load-bearing: the generator replaces only the span
between its BEGIN/END markers and preserves content on either side, so a
directive above BEGIN survives regeneration.

Verified rather than assumed — deleted the block, restarted the dev server, and
confirmed it was re-added below a surviving directive (lines 369 and 373), with
lint:md reporting 0 issues across 25 files.

The file began life as CLAUDE.md and still opened with that title and a line
addressing "Claude Code (claude.ai/code)", even though CLAUDE.md and GEMINI.md
are both symlinks to it and any agent reading its own conventional filename
gets these instructions.

Retitled to AGENTS.md and rewritten the opening to address AI coding agents
generally, noting the symlink arrangement so the next tool that wants a
different filename gets another symlink rather than a divergent copy.

The rest of the file needed no change — it is project documentation (build
commands, architecture, REST endpoints, deployment) with no vendor-specific
content: no .claude paths, slash commands, MCP or subagent references.

Not touched: the historical specs and plans under docs/superpowers/ that say
"update CLAUDE.md". They were accurate when written, the symlink means the
instruction still resolves, and rewriting finished design records to match a
later rename would be revisionist.

The env-var reference claimed it "is required for local sign-in". It is not.
lib/auth.ts:69 reads it inside buildOrgScope(), which returns an empty string
when unset, so the org:id scope is simply omitted and Zitadel authorizes any
instance-wide user — CDCF Org members included. The function's own comment
says as much: "If unset, behavior falls back to instance-wide auth ... so a
misconfigured deploy still works for CDCF Org users — it just doesn't enforce
the cross-Org isolation."

Restated as optional, with what setting it actually buys: registrations routed
into the CDCF Org, and sign-ins rejected from sibling-property Orgs and the
umbrella IAM admin. Kept the note that a value from the wrong instance does
fail sign-in confusingly, since that is a real trap when a production Org ID
is carried over to a local Zitadel.

Verified lib/auth.ts:69 still resolves to the env read before citing it again.

.env.local.example and the local-stack spec were checked and left alone —
both describe a WRONG value failing sign-in, which is accurate, rather than
claiming the variable is mandatory.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Every umbrella property runs its own local Zitadel — martyrology-api on 8080,
martyrology-frontend with its own .zitadel-data/, this repo on 8090 — but
ZITADEL_ISSUER, ZITADEL_INTERNAL_URL and ZITADEL_PAT_FILE all describe ONE
instance and were documented as going into the single shared
cdcf-infra/auth/.env.local. That is last-writer-wins across properties.

The failure mode is silent rather than loud: run --provision-martyrology while
the shared file still points at this repo and Martyrology's project is created
inside cdcf-website's Zitadel, because the PAT is a valid IAM_OWNER for that
instance and the call succeeds normally. The script echoes its target
("Target: local (issuer: http://localhost:8090, ...)"), but that is a log line,
not a guard.

setup-zitadel.sh already resolves ENV_FILE="${ENV_FILE:-.env.local}", so a
per-property file needs no change in cdcf-infra. Verified the override works
against the running instance before documenting it:

    ENV_FILE=.env.local.cdcf-website ./setup-zitadel.sh --target local --create-orgs
    -> Target: local (issuer: http://localhost:8090, internal: http://127.0.0.1:8090)
    -> ✓ Org already exists: CDCF (386706282788159494) ...

README, .env.local.example and spec §4 now all instruct
.env.local.cdcf-website with ENV_FILE, and §4 records why. The bats cases that
pin the port restatements across those files still pass — only the filename
changed, not the values.

The convention should be mirrored in cdcf-infra's own docs and the other
properties' READMEs; that is a separate repo and not in this PR's scope.
