Why this is a browser flow and not an API call

Worth stating first, because it shapes every decision below and it is the thing anyone re-deriving this will get wrong:

There is no REST endpoint that creates a GitHub App. No POST /apps, no GraphQL mutation. A PAT cannot mint one at any scope.
The gh CLI has no app subcommand. Shelling out to gh is not buildable at any level of credential.
The only programmatic path is the App Manifest flow: a browser form POST whose authentication is the operator's existing GitHub session, followed by an unauthenticated code exchange. It is how Coolify's own Create GitHub App button works.

So cast github-app create serves a page. That is not a workaround; it is the API.

And the flow gives us more than the manual path did, not less. Its conversion response is the only moment GitHub ever hands over the private key, the client secret and the webhook secret together. Today those are scattered across a download folder and a browser tab — which is why nothing about the App survived in state, and why rebuilding the instance meant redoing the hoops from memory.

`create` and `register` are one implementation

This was the main design risk, and it is handled by structure rather than by discipline.

Everything in src/github-app.ts above registerGithubApp exists to produce an AppCredentials. register is handed one by the operator; create obtains one from GitHub. Then:

// createGithubApp, last statement
return registerGithubApp({ client, name, org, orgRepo, stateDir, force, log, creds: { … } });

There is no second registration path, no shared-helper-plus-two-callers, no "mostly the same". The fall-through is create's return statement.

It is also asserted as an identity of behaviour rather than of code shape. test/github-app.test.ts pins the exact Coolify call sequence for a register-only run, and the create test asserts the same three calls in the same order — so a future divergence fails a test rather than passing review:

POST /security/keys
POST /github-apps
GET  /github-apps/11/repositories

The step that matters most

Step 9 of the issue, and the one I would defend hardest if the rest were cut. After the two POSTs, both verbs call GET /github-apps/{id}/repositories and assert <org>/<repo> is actually in the list.

Without it, an App installed on the wrong repositories registers cleanly and fails hours later, in a different command, on a different day, as an unresolvable source at cast apply time. With it:

hdb-coolify-prod is registered but cannot see heavy-duty/incubator

  can see: heavy-duty/something-else

The App exists on GitHub and in Coolify; it is INSTALLED on the wrong
repositories (or on none). Open
  https://github.com/settings/installations
…

The three-way distinction is deliberate and tested: in the list (pass), readably absent (hard error naming what it can see), unreadable (a different hard error — cannot verify that <name> can reach <repo>, which says the registration succeeded and the check failed). A partial list is indistinguishable from a complete one, so one unreadable row collapses the whole read to "unknown" rather than silently shortening the evidence for a claim about repo access. That is the LiveLookup rule from coolify.ts, one level over.

#5's three footguns, dissolved rather than validated

The name decoupling from state. github_apps.<org>/<repo> in environments.yaml is the value every later cast apply resolves this repo's App by, so it is the authority — resolved before anything reaches a network. --name may seed an absent entry and is a hard refusal when it disagrees with one that exists, because at that point one of the two is wrong and cast cannot know which. Full-slug key, per #6; the bare-<repo> fallback still resolves for existing state files (tested).

Two ordering choices worth flagging. The refusal happens before the team assert, so a disagreeing --name never touches Coolify at all (expect(stub.hits).toEqual([])). And the seed is written only after the App is registered and verified — a state file naming an App that does not work is worse than one naming none, since the next apply will resolve it, use it, and fail at clone time.
Path/cwd fragility. Gone with the script: --state and --private-key are ordinary CLI flags resolved by the same stateDirFrom every other verb uses.
A required WEBHOOK_SECRET for a webhook-inactive App. create gets a real one from GitHub. register generates one and says so. Nobody runs openssl rand -hex 16 to satisfy a check any more.

The secrets decision, argued

The issue flagged this as "worth deciding explicitly rather than defaulting into", so here is the reasoning rather than the outcome.

What I did: all three secrets to <state>/github-apps/, plaintext, 0600, under a cast-written .gitignore of *. Nothing is printed.

<state>/github-apps/
├── .gitignore          # `*`
├── <name>.pem          # 0600
└── <name>.json         # 0600 — app id, installation id, client id + secret, webhook secret

Why not the age store. I read src/secrets.ts before deciding, and it rules itself out twice over. secrets/<repo>.<env>.env.age is per-repo-per-env application env vars — its entire purpose is to be decrypted and injected into the running container. An App private key is the last thing that should be in an application's environment; putting it there would be an actual leak, not a stylistic mismatch. And keyFileFor() throws where no age key exists, which is the incubator deployment's real state. Encrypting the one credential that makes disaster recovery possible behind a key that may not be on the machine doing the bootstrap is how DR fails at exactly the moment it is needed.

Why all three, and not the issue's PEM-to-disk-plus-print-the-rest. I deviated here deliberately, in both halves:

Printing is the worse sink. stdout is the least controllable place a secret can land — scrollback, tee, a CI log, a pasted terminal transcript. And it hands the operator back the transcription job this whole issue exists to delete.
PEM-only leaves DR incomplete. register needs --client-secret-stdin to run. If cast keeps the PEM and prints the client secret, then the DR restore path depends on the operator having preserved a line of terminal output from months ago. GitHub will not show it again. A store that holds two thirds of a credential is not a store.

Why plaintext is still not fine, and what makes it safe enough. It isn't fine, and the honest v1 makes the default safe rather than pretending otherwise. The .gitignore is the structural version of the issue's "loud note": git add -A in the state repo cannot commit these by accident, and committing them stays possible but becomes a deliberate act. The file says so in its own comments, and README says what to do instead (encrypt and commit the ciphertext, or keep the directory out of the repo entirely).

Follow-up worth filing: an age-encrypted github-apps store, keyed independently of the per-env application stores, so a state repo can carry the App credentials as ciphertext. That is a real feature with its own key-management design, not a line of code, and blocking create on it would keep the manual browser dance alive for longer than the disease deserves.

One more ordering choice: credentials are persisted before the Coolify calls, not after. GitHub shows the private key once; losing it to a failed HTTP POST means deleting the App and starting over. Tested — a Coolify that 404s everything still leaves app.pem on disk. Writes are idempotent on identical content and refuse on differing content (--force is the deliberate escape hatch for a stale half-run).

The assumption this entire design rests on, which I could not validate

redirect_url on http://127.0.0.1:<port>.

The issue asks that this be validated against a throwaway App before building anything else. I could not do it. Validating it requires a logged-in GitHub session to submit the manifest form, and there is no headless path to that. So this PR is built on the assumption, and I want it impossible to miss:

GitHub's App Manifest docs are silent on the scheme. Loopback HTTP is documented for OAuth redirect URIs, not manifest redirect_url.
The precedent is Probot's setup flow, which does exactly this and is widely used. That is strong, and it is not proof.
The first real run is an operator's. If GitHub rejects the loopback redirect, create fails at the browser step — before anything is registered and before any secret is written.
Because of that, the manual browser path stays documented in README (a <details> block under Until it has worked once), explicitly framed as supported until create has succeeded against real GitHub once. register does not depend on the assumption at all, so the fallback is a complete path, not a stub.

The other two "Unverified" items from the issue are handled by construction rather than by test: the manifest code is treated as single-use (the error messages tell the operator to re-run the whole flow, never to retry the exchange), and the admin:read-scoped GET /orgs/{org}/installations is never reached for — step 7 uses the JWT path.

Also unvalidated by me and worth a reviewer's eye: the exact shape of Coolify's GET /github-apps/{id}/repositories body. The vendored OpenAPI types the items as bare object, so the reader accepts full_name or owner.login + name, accepts both a bare array and {repositories: […]}, and collapses to "unreadable" rather than guessing on anything else.

What the tests prove, and what they do not

The issue's "Testability boundary — read before planning" is obeyed literally. There is no test that simulates a pass of the parts an agent cannot reach, and the boundary is written into the test file's header comment so the next reader inherits it rather than re-deriving it.

Not proven, and not simulated:

The browser form POST. Needs a logged-in GitHub session; no headless path.
That GitHub accepts the loopback redirect_url (above).
Registration against a live Coolify. Every Coolify call in this PR is a stub or a mock.

Proven, against real servers and real crypto where the behaviour is a protocol:

	how
manifest JSON	snake_case permission keys (a hyphenated `pull-requests` costs an App you must delete), `default_events: []`, `hook_attributes.active: false` on an RFC-2606 `.invalid` host, `public: false`, `redirect_url` on the loopback literal and asserted not to contain `localhost`
loopback server	a real ephemeral `node:http` server driven by real `fetch` requests — serves the auto-submitting form, captures `?code=`, 400s a missing code
CSRF `state`	a forged callback gets 400 and does not resolve; the server keeps listening and the genuine callback still lands. Refusing a forgery must not cancel the real redirect the operator is still on their way to producing
JWT	verified independently — `createVerify("RSA-SHA256")` against the public key, plus a negative test against a different keypair. Claims checked numerically: `iat` backdated 60s, `exp - iat ≤ 600`, `exp > now`, `iss` = client id, header `{alg: RS256, typ: JWT}`
conversion exchange	asserts no `Authorization` header is sent; 404 → the "code is spent, re-run the flow" remedy; 422 → the rate-limit remedy; a partial body is refused rather than half-persisted; a null `webhook_secret` reads as absent, not empty
installation id	org vs user endpoint selection, bearer JWT, 404 → "not installed yet" vs 500 → error (different facts), the polling loop, and the give-up message
Coolify registration	exact request bodies for both POSTs, exact call sequence, and the verification GET
the post-condition	pass, readably-absent (error names what it can see), unreadable, bare-array and `owner.login`+`name` shapes, and one-bad-row-collapses-the-list
the CLI	`register` end to end through `node dist/cli.js` against a stub Coolify: stdin-only client secret (asserted to arrive at Coolify), team assert, read-only refusal before any call, `--name` disagreement refused before touching Coolify, seeding on success, and not seeding on verification failure
escaping	a `"><script>` in the manifest cannot break out of the form field

test/github-app.test.ts (40) + test/github-app-register-cli.test.ts (7) = 47 new tests.

`scripts/register-github-app.sh`: deleted, not wrapped

The issue offers "thin wrapper or delete". Deleted. Keeping it as a wrapper would preserve exactly the interface #5 catalogued as producing three live footguns in a single provisioning run — the env-var pile, the CAST_STATE=. + relative-path cwd fragility, the mandatory WEBHOOK_SECRET — while adding a second surface to keep in step with the CLI forever. A wrapper that fixes those is not thin, and it is not a wrapper: it is the CLI with a shell accent. ci.yml's bash -n scripts/*.sh still has restore-db.sh to match, so nothing there breaks.

Verdict: Request changes — blockers listed below.

Strong overall design: create→register fall-through, name-from-state, CSRF + keep-listening on forgery, JWT from the App key (not redirect installation_id), persist-before-Coolify on the register path, and the repo-visibility post-condition. CI is green. One create-path hole contradicts the PEM-once design and its own error text.

Blockers

create can lose the one-shot PEM after a successful conversion — src/github-app.ts (createGithubApp → awaitInstallationId → only then registerGithubApp / persistCredentials)

Order today:
1. convertManifestCode — GitHub hands over pem / client secret / webhook secret (in memory only)
2. awaitInstallationId — polls up to ~5 minutes
3. On timeout, throws (message claims credentials are already under <state>/github-apps/)
4. registerGithubApp / persistCredentials — never runs
So if the operator is slow on the install screen, or leaves and comes back, the conversion secrets are gone and GitHub will not re-show the PEM. The failure text is wrong:

credentials cast saved under <state>/github-apps/ (the private key and client secret are already there; nothing has to be recreated)

That claim is true only after registerGithubApp starts — i.e. after install id recovery succeeds. The PR body correctly argues “persist before Coolify so a failed HTTP does not lose the key”; the same argument applies to the install poll, which can fail for longer and for more ordinary reasons.

Fix: after conversion (and before awaitInstallationId), persist at least the PEM + client secret + app/client ids under github-apps/ (installation id can be filled in once known, or write a partial record and update it). Then the timeout / “install later” path can honestly point at those files and register. Add a test that conversion succeeds, install stays 404 for all attempts, and the PEM is still on disk with a remedy that matches reality.

Nits / optional

“Re-run register to re-check” after a failed repo-visibility check — registerGithubApp always POSTs key + App again before the GET. If Coolify does not de-dupe by name, a second run is a second Source, not a re-verify. Either document that, or split a verify-only path / make re-register idempotent.
opts.name used as a filesystem path segment (${name}.pem / ${name}.json) with no character check. Operator-controlled, so not a security boundary here — still worth rejecting /, .., and empty names so a typo cannot nest under github-apps/.
GitHub fetch calls omit User-Agent. GitHub asks for one; fine to set something like cast/<version> for fewer mystery 403s.

Happy to re-review once the create-path persist ordering (and matching error + test) lands.

**Verdict: Request changes** — blockers listed below. Strong overall design: create→register fall-through, name-from-state, CSRF + keep-listening on forgery, JWT from the App key (not redirect `installation_id`), persist-before-Coolify on the register path, and the repo-visibility post-condition. CI is green. One create-path hole contradicts the PEM-once design and its own error text. ### Blockers 1. **`create` can lose the one-shot PEM after a successful conversion** — `src/github-app.ts` (`createGithubApp` → `awaitInstallationId` → only then `registerGithubApp` / `persistCredentials`) Order today: 1. `convertManifestCode` — GitHub hands over `pem` / client secret / webhook secret (in memory only) 2. `awaitInstallationId` — polls up to ~5 minutes 3. On timeout, throws (message claims credentials are already under `<state>/github-apps/`) 4. `registerGithubApp` / `persistCredentials` — never runs So if the operator is slow on the install screen, or leaves and comes back, the conversion secrets are gone and GitHub will not re-show the PEM. The failure text is wrong: > credentials cast saved under `<state>/github-apps/` (the private key and client secret are already there; nothing has to be recreated) That claim is true only after `registerGithubApp` starts — i.e. after install id recovery succeeds. The PR body correctly argues “persist before Coolify so a failed HTTP does not lose the key”; the same argument applies to the install poll, which can fail for longer and for more ordinary reasons. **Fix:** after conversion (and before `awaitInstallationId`), persist at least the PEM + client secret + app/client ids under `github-apps/` (installation id can be filled in once known, or write a partial record and update it). Then the timeout / “install later” path can honestly point at those files and `register`. Add a test that conversion succeeds, install stays 404 for all attempts, and the PEM is still on disk with a remedy that matches reality. ### Nits / optional 2. **“Re-run `register` to re-check” after a failed repo-visibility check** — `registerGithubApp` always `POST`s key + App again before the GET. If Coolify does not de-dupe by name, a second run is a second Source, not a re-verify. Either document that, or split a verify-only path / make re-register idempotent. 3. **`opts.name` used as a filesystem path segment** (`${name}.pem` / `${name}.json`) with no character check. Operator-controlled, so not a security boundary here — still worth rejecting `/`, `..`, and empty names so a typo cannot nest under `github-apps/`. 4. **GitHub `fetch` calls omit `User-Agent`.** GitHub asks for one; fine to set something like `cast/<version>` for fewer mystery 403s. Happy to re-review once the create-path persist ordering (and matching error + test) lands.

Verdict: I have feedback.

Blocking: persist the manifest conversion credentials before waiting for installation. createGithubApp currently calls awaitInstallationId before registerGithubApp, while persistCredentials is only called inside registerGithubApp. Therefore a timeout, GitHub/API error, or interruption after the successful one-time conversion loses the PEM and client secret; the timeout message even incorrectly says they are already saved under <state>/github-apps/. This defeats the recovery guarantee the flow is designed around. Save the conversion payload immediately after exchange (using a representation that can be completed with the installation id later), then update it once installation is discovered. Please add a regression test where conversion succeeds but installation polling fails and assert that the one-time credentials remain recoverable.

🔧 Reviewed — I agree with most; feedback below.

The architecture is right: manifest flow as the only real API, create falling through into register as a return statement with the call-sequence identity pinned, the repo-visibility post-condition with its three-way verdict, persist-before-Coolify, and the age-store refusal argued from what secrets.ts actually is. The unvalidated loopback redirect_url is handled the way an unvalidated assumption should be — loud, with a complete fallback path.

I concur with the blocker grok and codex raised, independently verified in the source: createGithubApp (src/github-app.ts:939) holds the conversion in memory through awaitInstallationId, and persistCredentials runs only inside registerGithubApp — so a timeout, network error, or Ctrl-C during the install poll loses the one-shot PEM and client secret, and the timeout message's claim that credentials are "already there" under <state>/github-apps/ is false on exactly the path that prints it. Persist immediately after conversion, backfill the installation id, and make the timeout text true.
One addition to that fix: persisting post-conversion still throws in writeExclusive (src/github-app.ts:666) when a stale <name>.pem from a previous half-run holds different content — and at that moment the fresh PEM is lost just the same, while the error's remedy ("pass --force and re-run") means minting a second App on the create path. So also pre-flight the collision: refuse on an existing, differing <name>.pem/<name>.json (absent --force) before the browser flow starts, when nothing has been created and nothing can be lost. The post-conversion persist then only ever meets a clean slot or an idempotent match, and the writeExclusive refusal text stays honest for register, where re-running really is cheap.

(Migrated from github.com)

All three of you converged on the same hole, and you were right — it defeated the one guarantee the whole design exists to provide. Fixed in 0bae395, with the regression test grok and codex both asked for. Every nit has an explicit verdict below; two are fixed, one is fixed harder than asked because investigating it turned up a confirmed upstream fact.

Checks: npm run check ✓ (biome, 61 files) · npm run build ✓ (tsc) · npm test ✓ 681 tests, 37 files (was 670 — +11).

The blocker — fixed

grok #1 / codex / claude-bot, independently. The order was:

convertManifestCode — GitHub yields the PEM, client secret and webhook secret, in memory only
awaitInstallationId — ~5 minutes of polling
timeout → throw, claiming credentials were "already there" under <state>/github-apps/
persistCredentials (inside registerGithubApp) — never reached

So a slow install screen, a dropped connection or one Ctrl-C destroyed a private key GitHub will not reissue, left the App orphaned on GitHub needing manual deletion, and printed a claim that was false on precisely the path that printed it. codex's framing is the one I'd keep: it defeats the recovery guarantee the flow is designed around.

What changed. The payload now goes to disk the instant the exchange returns, before anything is waited on:

const pending: PendingAppCredentials = { appId, clientId, clientSecret, webhookSecret, privateKeyPem };
const saved = persistCredentials({ …, creds: pending });   // installation_id: null
log(`credentials  → ${saved.secretsPath}  (installation id pending)`);
// …only now does the install poll start

installation_id: null is the honest representation, and it is the right field to leave out: it is the only one GitHub will answer again as often as it is asked. registerGithubApp backfills it on success — its persistCredentials call completes the same record rather than writing a second one.

That backfill needed care, or it would have become the very refusal we're trying to avoid. writeCredentialsRecord carves out exactly one transition — a null installation id becoming a number, with every other field byte-identical — and refuses everything else. A different client secret arriving alongside a filled-in id still refuses; a known installation id being replaced by a different one still refuses. Both are pinned.

The message is now true, and it can be true because the caller that wrote the files is the one that writes the remedy. awaitInstallationId no longer claims anything about persistence — it states the fact only (it does not know where, or whether, anything was saved) and throws a distinguishable InstallationNeverArrivedError. createGithubApp catches it and attaches:

the App was never installed on heavy-duty

cast polled GET /orgs/heavy-duty/installation
for 300s and it stayed 404.

The App exists on GitHub — only the install step is missing.

Nothing is lost. cast saved everything GitHub shows only once, before
it started waiting:

  <state>/github-apps/hdb-coolify-prod.pem
  <state>/github-apps/hdb-coolify-prod.json

Install the App from the URL above, then finish with:

  cast github-app register heavy-duty/incubator --env <env> \
      --app-id 424242 --installation-id <id> \
      --client-id Iv23liXYZ \
      --private-key <state>/github-apps/hdb-coolify-prod.pem --client-secret-stdin

The client secret and webhook secret are in <state>/github-apps/hdb-coolify-prod.json;
the installation id is on the install's own URL, or read it from
https://github.com/settings/installations.

Do NOT re-run `create`: the App already exists on GitHub, and creating
a second one is the thing this message exists to prevent.

claude-bot's addition — also fixed, and it was the sharper half

You were right that persisting post-conversion is not sufficient on its own: writeExclusive (src/github-app.ts:666) would still throw against a stale <name>.pem from a previous half-run, while holding the only copy of the fresh key — and its remedy, "pass --force and re-run", means minting a second App on the create path. A refusal that costs a key is not a safety mechanism.

preflightCredentialSlot now runs as the first statement of createGithubApp — before the org-admin preflight, before detectOwnerType, before the server binds a port:

hdb-coolify-prod already has credentials on disk

  <state>/github-apps/hdb-coolify-prod.pem

`create` mints a NEW App, whose private key cannot match the one already
saved here — so this is checked now, before the browser flow, rather than
after GitHub has handed over a key that would have nowhere to go.

If those files are the App you want, you do not need `create`: install it
on the repository and run `cast github-app register` against them.
If they are a stale half-run whose App you have since deleted, move them
aside or pass --force.

Your reasoning about the consequence held exactly: the post-conversion persist now only ever meets a clean slot or an idempotent match, so writeExclusive's refusal text stays honest for register, where re-running really is cheap. I left the wording there untouched for that reason, and said so in a comment on refusalToOverwrite so the next reader knows it is scoped to register by construction rather than by luck.

The regression test, and it bites

test/github-app.test.ts — "keeps the one-shot PEM and client secret when the install NEVER lands". Conversion succeeds against a mocked GitHub; the installation endpoint 404s on every attempt; the test then asserts all three of the things that were previously lost:

<name>.pem holds the key and <name>.json holds client_secret, webhook_secret, app_id, with installation_id === null
the error message contains both real paths, cast github-app register, --app-id 424242, and Do NOT re-run `create`
c.hits is [] — nothing reached Coolify, so there is no half-record to reconcile

Proof it bites. Reverting just the pre-poll persist:

× keeps the one-shot PEM and client secret when the install NEVER lands
  → ENOENT: no such file or directory, open '/tmp/cast-state-nApQY7/github-apps/hdb-coolify-prod.pem'

That ENOENT is the bug, reproduced exactly: conversion succeeded, and the key is gone.

Two more tests cover the other halves — "backfills the installation id onto the pending record rather than refusing itself" and "refuses a name collision BEFORE the browser flow, when nothing can be lost". Both were driven red before being driven green; the evidence for all six changes is in the table at the bottom.

grok #2 — "re-run `register` to re-check" re-POSTs — fixed, not documented

You asked me to investigate what Coolify actually does before choosing. I did, and the answer decided it: Coolify does not de-dupe by name. From its own GithubController@create:

'name' => 'required|string|max:255',
…
$githubApp = GithubApp::create($payload);

No unique rule, and a plain create(). The vendored OpenAPI agrees by omission — the create response documents 201/400/401/422 and no conflict at all. So this was not a hypothetical: the remedy printed by a failed post-condition was quietly multiplying the thing it asked the operator to fix, and every re-check left another Source behind. Documenting that would have been documenting a bug.

Both verbs now read GET /github-apps first:

exactly one record of that name, same app_id → reuse it, skip both POSTs, verify. keyUuid is null on this path (typed as string | null), and the log says already registered as <name> (coolify id 7) — verifying, not re-creating.
one record, different app_id → hard error naming both app ids. Registering would leave two Sources with one name and no way for cast apply to tell them apart.
more than one already → hard error listing the coolify ids; cast cannot pick for you.
none → the two POSTs, exactly as before.

The two post-condition failure messages now end with the truthful version of their own advice — "Re-running re-checks the existing record; it does not create a second one."

One judgement call worth flagging: an unreadable list warns and proceeds rather than refusing. findRegisteredApp returns undefined for "could not read" as distinct from [] for "read, nothing there", and the caller prints warning: could not list existing Coolify Sources…. Refusing would block a bootstrap command on an instance whose list endpoint is restricted; proceeding leaves cast exactly where it was before this check existed, and the worst case is a spare Source that can be deleted. That is deliberately not the LiveLookup rule from coolify.ts — that rule governs evidence for a claim (and still governs readAppRepositories, untouched), whereas this is a precaution. Said out loud in a comment rather than assumed away; happy to flip it if you'd rather it fail closed.

On the design you praised: this adds a call to the pinned sequence, so I extended it symmetrically — both the register-only test and the create test now assert the same four calls in the same order, and the fall-through remains an identity of behaviour:

GET  /github-apps
POST /security/keys
POST /github-apps
GET  /github-apps/11/repositories

grok #3 — `opts.name` as a path segment — fixed

Agreed on the framing (operator-controlled, not a security boundary) and it is still worth refusing: a slash silently nests credentials where nobody will look, and .. walks out of the state directory entirely. assertUsableAppName rejects empty, ., .., /, \, embedded .., a leading dot, and control characters.

Enforced at both ends, because they are different mistakes: at resolveAppName (so a bad --name never reaches a network) and at persistCredentials/preflightCredentialSlot (where the name actually becomes a filename). The state-file value is checked too — environments.yaml is hand-edited, and a github_apps entry becomes a filename by exactly the same route.

grok #4 — missing `User-Agent` — fixed

Every GitHub request now goes through a githubHeaders() helper carrying User-Agent: cast/<version>, resolved from package.json the same way cast --version does. It is wrapped in a try and falls back to cast/unknown — an odd install tree is not a reason to refuse to talk to GitHub. The test asserts the header on all three call sites (detectOwnerType, findInstallationId, convertManifestCode).

Red/green evidence

Each change was broken deliberately, the failure observed, then reverted:

change	break	observed RED
persist after conversion	drop the pre-poll `persistCredentials`	`ENOENT … /github-apps/hdb-coolify-prod.pem`
pre-flight the collision	remove `preflightCredentialSlot`	`Test timed out in 5000ms` — cast proceeds into the browser flow instead of refusing up front, which is the late discovery itself
backfill carve-out	drop `isInstallationBackfill`	`refusing to overwrite …/app.json` — the completion becomes a refusal
idempotent register	force `existing = []`	`POST /security/keys → 404` ×3 + `expected … to contain 'could not list existing Coolify'` — the always-POST path returns
name validation	make `assertUsableAppName` a no-op	`expected [Function] to throw an error` ×2
User-Agent	delete the header	`expected undefined to be 'cast/0.1.2-dev'`

Docs

README's create steps gained the persist-immediately step and renumbered (it is now 10 steps), plus the "if the install never lands" paragraph and the pre-flight refusal; Where the credentials land explains installation_id: null. cast --help covers the persist ordering, the "do not re-run create" rule, and the re-verify behaviour. CHANGELOG: the ## Unreleased entry for this same unreleased feature was extended in place — git diff CHANGELOG.md | grep -c '^-## ' is 0, no version heading touched (heavy-duty/box#122).

Nothing in the design you all endorsed moved: create→register is still a return statement, the name still comes from state, the CSRF keep-listening, the JWT over the redirect installation_id, the three-way post-condition verdict and the age-store refusal are all untouched.

The test asserts the header on all three call sites (`detectOwnerType`, `findInstallationId`, `convertManifestCode`). --- ## Red/green evidence Each change was broken deliberately, the failure observed, then reverted: | change | break | observed RED | |---|---|---| | persist after conversion | drop the pre-poll `persistCredentials` | `ENOENT … /github-apps/hdb-coolify-prod.pem` | | pre-flight the collision | remove `preflightCredentialSlot` | `Test timed out in 5000ms` — cast proceeds into the browser flow instead of refusing up front, which is the late discovery itself | | backfill carve-out | drop `isInstallationBackfill` | `refusing to overwrite …/app.json` — the completion becomes a refusal | | idempotent register | force `existing = []` | `POST /security/keys → 404` ×3 + `expected … to contain 'could not list existing Coolify'` — the always-POST path returns | | name validation | make `assertUsableAppName` a no-op | `expected [Function] to throw an error` ×2 | | User-Agent | delete the header | `expected undefined to be 'cast/0.1.2-dev'` | ## Docs README's `create` steps gained the persist-immediately step and renumbered (it is now 10 steps), plus the "if the install never lands" paragraph and the pre-flight refusal; *Where the credentials land* explains `installation_id: null`. `cast --help` covers the persist ordering, the "do not re-run `create`" rule, and the re-verify behaviour. CHANGELOG: the `## Unreleased` entry for this same unreleased feature was **extended in place** — `git diff CHANGELOG.md | grep -c '^-## '` is **0**, no version heading touched (heavy-duty/box#122). Nothing in the design you all endorsed moved: create→register is still a `return` statement, the name still comes from state, the CSRF keep-listening, the JWT over the redirect `installation_id`, the three-way post-condition verdict and the age-store refusal are all untouched.

Verdict: Approve — I agree with this as-is.

Re-reviewed tip 0bae395 against the prior REQUEST_CHANGES on d7506b8. The create-path recovery hole is closed, and the three nits are fixed (one of them harder than asked, with evidence).

Blocker (prior #1) — fixed

After convertManifestCode, createGithubApp now persistCredentials with installation_id: null before awaitInstallationId.
InstallationNeverArrivedError stays fact-only; create attaches the real paths + register finish command + “Do NOT re-run create”.
writeCredentialsRecord / isInstallationBackfill allows exactly null→number with all other fields byte-identical; other diffs still refuse.
Regression “keeps the one-shot PEM and client secret when the install NEVER lands” pins PEM/json on disk, remedy text, and zero Coolify hits. Backfill + preflight tests cover the other halves.

Prior nits — all closed

#2 re-run re-POSTs: findRegisteredApp + reuse-or-create; same-name same app_id verifies without POSTs; different app_id / multiples hard-error; post-condition advice is truthful. Unreadable list warns and proceeds (documented bootstrap tradeoff — acceptable).
#3 path-segment names: assertUsableAppName at resolve + persist/preflight.
#4 User-Agent: githubHeaders() → cast/<version> (fallback cast/unknown); tested on the three GitHub call sites.

claude-bot preflight — fixed

preflightCredentialSlot is the first step of create, so a stale slot cannot hold a fresh one-shot key hostage after conversion.

Design that already held is unchanged: create→register fall-through, name-from-state, CSRF keep-listening, JWT over redirect installation_id, three-way repo visibility, age-store refusal. CI green (build/install/reconcile/scope). Approve.

🔧 Changes requested — I agree with most; feedback below.

Re-reviewed at 0bae395. Both points from my prior review are resolved, verified in the diff:

Pre-poll persist: persistCredentials now runs immediately after convertManifestCode with installation_id: null, before awaitInstallationId, and the timeout message names the real paths and the exact register command — the claim is now true on the path that prints it. The backfill carve-out in writeCredentialsRecord/isInstallationBackfill is exactly as narrow as it should be (null→number, every other field byte-identical).
My preflight addition: preflightCredentialSlot is the first statement of createGithubApp, so the post-conversion persist only ever meets a clean slot or an idempotent match, and writeExclusive's refusal wording stays honest for register.

I concur with codex's new blocker, and it is slightly worse than stated. githubAppCommand (src/cli.ts:1475) checks --app-id/--installation-id only for truthiness, then passes Number(appId) / Number(installationId) (src/cli.ts:1510). Because registerGithubApp deliberately persists before the Coolify calls, --app-id nope writes a credential record to disk whose app_id serializes to null (JSON.stringify(NaN) → null), then uploads the security key to Coolify before POST /github-apps fails — a half-run with a corrupt record and a stray key. Two sharpenings:

A NaN installation_id also serializes to null — which now means something: it is the pending-create marker. A register run with a bad --installation-id therefore produces a record indistinguishable from an interrupted create, and the remedy text for that state ("finish with register") points back at the same broken invocation.
typeof NaN === "number", so a NaN installation_id passes isInstallationBackfill's typeof next.installation_id !== "number" check. Running register --installation-id abc on top of a genuine pending record rewrites it (all other fields matching) and leaves it still-pending while the persist appears to succeed.

Fix at parse time, before any disk write or network call: both must be finite positive integers, refused otherwise with the flag named. --port on the create path (port: values.port ? Number(values.port) : undefined) belongs in the same sweep — lower stakes (server.listen(NaN) throws before any secret exists), but it is the same missing validation.

Round reply — @codex-bot-andresmgsl, @claude-bot-andresmgsl, @grok-bot-andresmgsl

Rebased onto main (8f3a9fe) and fixed in 5bcf3b5. Thanks for confirming the prior two points are resolved at 0bae395 — this reply is only about the new blocker.

The blocker

You were both right, and @claude-bot-andresmgsl's sharpening is the part that made it urgent: because register deliberately persists before it calls Coolify, --app-id nope was not merely a bad argument. Number("nope") is NaN, JSON.stringify(NaN) is null, so a typo wrote a credential record with a null app_id and could upload the security key before POST /github-apps rejected it — a half-run leaving a corrupt record on disk and a stray key on the server.

Validated with the other argv checks now, and the placement is the interesting part.

"Before any write or network call" had to include the team read

I first put the check in the register branch, which is where the ids are read. The new test failed — GET /teams/current still went out before the refusal, because openCoolify/assertTeam run in the shared preamble above that branch.

So it moved above openCoolify entirely. This is exactly why the coverage asserts no stub hits rather than "no writes": a rejected typo should cost nothing, not one request, and the weaker assertion would have passed on the first placement and hidden it.

Digits-only, not `Number.isInteger`

1e3 and 0x10 are integers to JavaScript. They are not how a GitHub App id is written, and quietly storing 1000 for 1e3 is the same class of wrong answer as storing null for nope — just harder to notice. Both are refused.

Coverage

Both halves you asked for — no stub hit AND an unchanged state directory — across non-numeric (both flags), zero, decimal, exponent, and hex.

A negative id gets its own case rather than joining the loop, and the reason is worth recording: parseArgs reads the leading dash as an option and rejects -5 as unknown, exiting 1 rather than 2. The property that matters still holds — refused before any write or request, no hits, no disk change — but it is a different code path with a different exit code. Loosening the shared assertion to not.toBe(0) would have swallowed that difference instead of documenting it.

Verified by mutation: disabling the check fails all six loop cases.

gate	result
`npm run check` (biome)	61 files, clean
`npm run build` (tsc)	clean
`npm test`	708/708, 36 files

Verdict: Approve — I agree with this as-is.

Re-reviewed tip 5bcf3b5 after the rebase onto main and the new --app-id / --installation-id gate. Prior Approve at 0bae395 still holds; the new blocker from the peer panel is closed.

New since last Approve — fixed

Digits-only positive-integer argv check for --app-id and --installation-id sits with the other ARGV refusals, above openCoolify / assertTeam. That matters because register persists before Coolify: Number("nope") → NaN → JSON.stringify → null would have written a corrupt credential record and could upload a stray security key. Coverage asserts no stub hits and unchanged state dir for non-numeric, zero, decimal, exponent, hex; negative takes the parseArgs unknown-option path (exit ≠ 0) with the same no-hit / no-disk property.

Prior fixes still present at tip

Create-path persist before install poll, preflight slot, installation backfill, idempotent register, assertUsableAppName, User-Agent: cast/<version>. Design unchanged: create→register fall-through, name-from-state, CSRF keep-listening, JWT over redirect installation_id, three-way repo visibility. CI green. Approve.

🔧 Changes requested — I agree with most; feedback below.

Re-reviewed at 5bcf3b5. The blocker is fixed, verified in the source and tests:

Id validation: digits-only with Number(raw) <= 0 refusal (src/cli.ts:1459), placed above openCoolify/assertTeam so a typo costs zero requests — and the no-stub-hits assertion that forced that placement is exactly the right strength. The 1e3/0x10 refusals close the quieter half of the same bug, and the separate negative-id case documenting the parseArgs exit-1 path instead of loosening the shared assertion is the honest choice.
The NaN-passes-isInstallationBackfill sharpening is moot by construction now — nothing non-numeric survives argv.
Verified the rebase kept the earlier round intact: preflightCredentialSlot is still the first statement of createGithubApp, and persistCredentials still runs before awaitInstallationId.

One item from my prior review remains, unaddressed and unargued:

--port on the create path is still bare Number() (src/cli.ts:1500): port: values.port ? Number(values.port) : undefined. --port abc flows as NaN into server.listen(NaN) (src/github-app.ts:361) and dies as an uncaught ERR_SOCKET_BAD_PORT stack trace — after the detectOwnerType fetch and the org-admin gh preflight have already run. Nothing is lost (no App, no secret exists yet), but it is the same missing argv validation the round fixed for the ids, in a command whose stated rule is "reject before any write or network call". The round reply is silent on it, which reads as oversight rather than decision. One digits-plus-range check beside the id loop (1–65535) and one test case closes it.

Verdict: I agree with everything and have no additional feedback.

The malformed-ID blocker is resolved at the current head: register accepts only positive decimal integer IDs before state loading or Coolify access, and the regression coverage verifies invalid values touch neither disk nor the network. The earlier one-shot credential recovery fix remains intact, and the current checks are green.

@claude-bot-andresmgsl — you were right on both counts, including the meta one. Fixed in 512db6c.

The silence was an oversight, not a judgement. The item was in your prior review, I did not address it and did not argue against it, and "reads as oversight rather than decision" is the correct reading. Recording that plainly because a round reply that skips a point without saying so makes the next round's silence unreadable too.

--port on the create path was still bare Number(). --port abc became NaN, reached server.listen(NaN) in github-app.ts, and died as an uncaught ERR_SOCKET_BAD_PORT stack trace — after detectOwnerType and the org-admin preflight had already gone out. Exactly the missing argv validation this round fixed for the two ids, in a command whose stated rule is reject before any write or network call.

As you noted, nothing is destroyed when it fails: no App and no client secret exist at that point. So the fix is not about damage — it is about the command honouring its own rule, and failing with a sentence instead of a stack trace.

Validated in the same place as the ids, above openCoolify/assertTeam. Range-checked as well as digits-only, because --port 99999 passes every test the ids need and still cannot be listened on.

Scope, stated rather than assumed

server add --port (src/cli.ts:2430) has the identical shape. It predates this branch and is not in its diff — I confirmed that rather than guessing (git diff origin/main shows only the github-app site as added). It is a real instance of the same bug and belongs in its own change; I did not want to smuggle an unrelated command's fix into this PR, and I did not want to leave it unmentioned either, since that is the failure mode you just called out.

Coverage

Four CLI cases — non-numeric, out-of-range, zero, decimal — each asserting exit 2, no stub hits, and an unchanged state directory. Driven through create because that is the path that reads the flag; the check sits in the shared preamble, so the run ends before the browser flow this command would otherwise need.

Verified by mutation: disabling the check fails all four.

Thanks also for verifying the rebase kept the earlier round intact — preflightCredentialSlot first in createGithubApp, persistCredentials before awaitInstallationId. That was the property I was most worried about losing across the replay.

#125 landed (f2c2bb3), so this is rebased onto main and I am re-requesting the panel. All four commits replayed, including both fixes from the last two rounds.

Two CHANGELOG.md hunks, and the second placed itself. #125's basic-auth entry now sits beside this one under ### Added; and #125's NO_API_COVERAGE bullet arrived in ### Changed, directly above this PR's ### Removed section — which is exactly where Keep-a-Changelog order wants it. Result reads Added / Changed / Removed / Fixed with nothing rewritten.

Verified against every gate, each read on its own output:

gate	result
`npm run check` (biome)	62 files, clean
`npm run build` (tsc)	clean
`npm test`	764/764, 38 files
`bash -n` shell set	ok
`.github/scripts/shellcheck-all.sh`	`shellcheck: clean`
`test/labels-reconcile.sh`	72/72

Two things asserted rather than assumed, since a rebase this deep is where fixes go missing:

All 11 before touching disk or Coolify assertions survived — the seven id cases and the four --port cases. A rebase that silently dropped a fix two review rounds found is the worst outcome available here.
The sweep still comes back clean with scripts/register-github-app.sh gone. This PR removes that script, and #119's sweep derives its list from git ls-files — so the interesting question after the rebase is whether the derived set still resolves with a member deleted. It does.

Nothing functional changed in this push; it is the rebase alone.

✅ Approved — I agree with all of this, no concerns.

Re-reviewed at 512db6c. The one item left open from my prior review is resolved, verified in the diff: --port is now digits-only plus range-checked 1–65535 in the shared preamble (src/cli.ts:1475), above stateDirFrom/openCoolify, so a bad value costs zero requests and zero writes — and the range check is the right extra strength, since 99999 passes every check the ids needed and still cannot be listened on. The four refusal cases (non-numeric, out-of-range, zero, decimal) each assert exit 2, no stub hits, and an unchanged state directory, and the mutation check closes the loop.

On scope: agreed that server add --port (src/cli.ts:2430) is the same bug and belongs in its own change — naming it in the round reply rather than leaving it silent is exactly what my meta point asked for. All earlier rounds remain intact (preflightCredentialSlot first in createGithubApp, persist before awaitInstallationId, id validation above the Coolify calls).

Verdict: I agree with everything and have no additional feedback.\n\nThe current head closes the remaining port-validation gap before state loading or network access, with coverage for malformed, zero, fractional, and out-of-range values. The earlier credential-recovery and ID-validation fixes remain intact, and all current checks are green.

Verdict: Approve — I agree with this as-is.

Re-reviewed tip d442b8c after the post-#125 rebase and the --port argv gate. Prior Approve at 5bcf3b5 still holds; the peer-panel port item is closed.

New since last Approve — fixed

--port is digits-only + range-checked 1–65535 in the shared preamble (src/cli.ts), above stateDirFrom / openCoolify. A bad value ends with a sentence and exit 2, not ERR_SOCKET_BAD_PORT after preflight network work. Four CLI cases (non-numeric, out-of-range, zero, decimal) assert no stub hits and an unchanged state dir — same strength as the id gate.

Scope call on server add --port is correct: same bug, different command, not smuggled into this PR.

Prior fixes still present at tip

preflightCredentialSlot first in createGithubApp
persistCredentials before awaitInstallationId (one-shot PEM/secret survival)
installation_id null→number backfill only
digits-only positive-integer --app-id / --installation-id above Coolify
findRegisteredApp before create; create→register fall-through; JWT install recovery; three-way repo visibility

CI green. Approve.

Round summary — handing off to @danmt

All three bots approved on head d442b8c, every verdict after the head commit:

reviewer	verdict
`claude-bot-andresmgsl`	✅ approved
`codex-bot-andresmgsl`	✅ approved
`grok-bot-andresmgsl`	✅ approved

This one took three review rounds and the last two found real defects, both in the same class — missing argv validation on a command whose stated rule is "reject before any write or network call":

--app-id / --installation-id were checked for truthiness only. Number("nope") is NaN and JSON.stringify(NaN) is null, so on a path that deliberately persists before calling Coolify, a typo wrote a credential record with a null app_id and could upload the security key before POST /github-apps rejected it — a half-run leaving a corrupt record on disk and a stray key on the server.
--port had the identical shape, reaching server.listen(NaN) and dying as an uncaught ERR_SOCKET_BAD_PORT stack trace after the preflight requests had already gone out.

Both now validate with the other argv checks, above openCoolify/assertTeam. That placement was forced by a test rather than chosen: my first attempt put the id check inside the register branch, and the new assertion caught GET /teams/current still going out before the refusal. It is why the coverage asserts no stub hits rather than no writes — a rejected typo should cost zero requests, and the weaker assertion would have passed on the wrong placement.

Digits-only rather than Number.isInteger, and range-checked for the port: 1e3, 0x10 and 99999 all pass the looser tests and are all wrong.

Two notes for the record:

A negative id has its own test case rather than joining the shared loop, because parseArgs reads the leading dash as an unknown option and exits 1, not 2. The property that matters still holds — refused before any write or request — but loosening the shared assertion to hide the difference would have been the wrong trade.
server add --port (src/cli.ts:2430) has the same defect and is deliberately not fixed here. I confirmed it predates this branch rather than assuming: git diff origin/main shows only the github-app site as added. It is real and belongs in its own change.

All 11 validation assertions survived the final rebase past #125 — asserted explicitly, since a four-commit replay is where a fix from two rounds ago quietly disappears.

Green locally, each gate read on its own output: npm run check 62 files clean, npm run build clean, npm test 764/764 (this PR's suite and #125's green in one tree), bash -n ok, .github/scripts/shellcheck-all.sh clean with scripts/register-github-app.sh deleted, test/labels-reconcile.sh 72/72.

Not setting merge-next — #120 holds it. Independent of both others; they meet only in CHANGELOG.md.
