Transact provider config and credential writes (3/4)

[PierrunoYT]

Summary

This is PR 3 of the 4-PR split of #725, following the review request to separate provider identity, credential ownership, transactional persistence, and selection UX into independently reviewable contracts.

Important

This PR is stacked on #893 and should be merged after it.
GitHub requires this cross-fork PR to target an upstream branch, so the displayed diff includes #892 and #893.
Review only the final commit: fix(providers): transact provider config and keys. Once the predecessors merge, this diff will collapse to that commit.

What changed

• Adds one config-layer provider transaction owning exclusive cross-process locking, config read and validation, in-memory mutation, credential changes, atomic config publication, conditional rollback, and ownership-checked release.
• Fails closed when lock acquisition, timeout, creation, cleanup, or release fails. Age-based lock stealing is intentionally removed because a slow live keyring holder cannot safely be distinguished from an abandoned lock by age.
• Routes provider add/setup, catalog ensure, OpenRouter key persistence, active/model writes, manager edit/rename/remove, marker cleanup, logout API-key cleanup, STT credential writes, and plaintext-key migration through the shared boundary.
• Commits OpenRouter profile creation, minted-key storage, and marker publication together.
• Rolls credentials back only when the stored value still exactly matches the value written by the failed transaction.

Scope

Provider-selection presentation, ZERO_PROVIDER explanations, and case-only live-session synchronization remain in PR 4.

Validation

• make fmt-check
• go vet ./...
• go test ./...
• go test -race ./internal/config ./internal/cli ./internal/tui -count=1
• go run ./cmd/zero-release build
• go run ./cmd/zero-release smoke
• make lint-static (0 issues.)
• make vulncheck (No vulnerabilities found.)
• git diff HEAD --check

Refs #721. Split of #725. Stacked on #893.

Walkthrough

This change centralizes provider identity resolution and credential mutations. Provider writes now use transactions with locking and rollback. CLI and TUI authentication flows preflight configuration before saving credentials. Provider repair, status, refresh, logout, and model management use canonical identities.

Changes

Provider identity and credential transaction safety

Layer / File(s)	Summary
Identity resolution and provider matching internal/config/..., internal/credstore/...	Provider resolution now supports exact names, normalized identities, catalog ownership, unnamed OpenAI profiles, Unicode distinctions, and ambiguity checks.
Credential transactions and locking internal/config/credentials.go, internal/config/provider_commit.go, internal/config/provider_lock_*, internal/credstore/credstore.go	Credential and provider changes now use serialized transactions, rollback, OS-level locks, lock-release error handling, and transactional plaintext-key migration.
CLI authentication and provider commands internal/cli/...	CLI authentication, provider mutations, setup, repair, status, refresh, logout, migration reporting, and dependency wiring now use resolved identities and transactional configuration APIs.
OAuth manager and TUI management internal/oauth/..., internal/tui/...	OAuth flows now preflight configuration, commit tokens through callbacks, enforce catalog ownership, synchronize provider state, and redact credential-related errors.
Diagnostics and documentation internal/doctor/..., README*, CHANGELOG.md, docs/oauth-subscriptions.md	Diagnostics report provider-resolution failures, and documentation describes provider repair and OAuth validation behavior.

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🟠 High · up to 2ed0d

This PR centralizes provider and credential writes behind cross-process transactions, but a lock ownership race can still permit concurrent updates and cause provider or credential changes to be lost or overwritten. Some error paths may also expose configuration details, and tests depend on the host credential backend. The lock race should be fixed before merging.

Pin the credential-store backend in these two logout tests.

TestRunAuthLogoutResolvesCatalogIdentity and TestRunAuthLogoutDeletesCatalogIDToken do not set ZERO_CRED_STORAGE. Every other logout test in this file does (Lines 610, 654, 702, 742, 872, 919, 962).

Both tests still reach config.DeleteProviderCredentials, which opens the provider key store. Without the override the backend can resolve to the OS keyring. Both tests assert exitSuccess, so a keyring that is absent or locked turns them into environment-dependent failures on a headless runner.

💚 Proposed fix

 func TestRunAuthLogoutResolvesCatalogIdentity(t *testing.T) {

Add an ambiguous-catalog-id failure case.

The table covers only resolutions that succeed. remove is destructive, and the resolution rule that protects it is "reject a catalog id claimed by more than one profile". Nothing here pins that rule for providers use|remove|rename.

Do not discard the credentialStore() error in setKey and deleteKey.

The code is correct today. snapshotCredential opens the store first and returns any error, and credentialStore() memoizes op.store, so the second call cannot fail. The safety depends on that call order alone. If snapshotCredential ever returns early before the store is opened, store becomes nil and the next store.Set/store.Delete panics.

Propagate the error instead of discarding it.

♻️ Proposed fix

 func (op *providerProfileOperation) setKey(name, value string) error {
 	identity := credstore.NormalizeProvider(name)
 	snapshot, err := op.snapshotCredential(name)
 	if err != nil {
 		return err
 	}

Surface rollback failures instead of discarding them.

The value-comparison guard is right: a credential is only restored when the store still holds exactly what this transaction wrote, so a concurrent winner's secret is never clobbered.

The two restore calls discard their errors. If publication fails and the restore also fails, the credential store and config.json diverge, and the caller sees only the publication error. The user then has a stored key with no matching row, and no signal that cleanup failed.

Return the rollback error from rollbackCredentials and join it into the error runProviderProfileOperation returns, the same way the lock-release error is joined at line 52.

Store a newly supplied key directly under the new name instead of writing it twice.

When an edit supplies both APIKey and an identity-changing NewName, line 799 stores the key under previousName, then lines 810-820 read it back, store it under newName, and delete previousName. The result is correct, and rollback covers every intermediate step, but one logical edit becomes two store writes plus a delete.

Two smaller points in the same block:

• Lines 783 and 790 call credstore.NormalizeProvider directly for the collision check. RenameProvider expresses the identical check through the sameProviderIdentity helper. Use the helper in both places.
• The migration Get at line 810 reads a value this same transaction may have just written, which makes the data flow harder to follow than it needs to be.

Resolve the target name first, then capture the key once under that name.

Silent continue on setKey failure leaves the plaintext key in config.json with no signal.

Leaving the plaintext key in place on a failed store write is the right call, and it matches the documented behavior of the legacy MigratePlaintextProviderKeys at lines 194-197. The new function drops the comment that explained why. Keep that rationale here, since this is the production startup path.

The gap is reporting. A credential-store failure produces (migrated, nil). Startup continues, the secret stays in cleartext in config.json, and nothing tells the user the migration did not complete. Return a count of skipped profiles or a joined error so the caller can warn.

♻️ Proposed change

 	migrated := 0
+	var skipped error
 	_, err := runProviderProfileOperation(path, true, false, func(op *providerProfileOperation) error {
 		for index := range op.config.Providers {

+				// Leave the plaintext key untouched; a failed Set must not strand it.

blocked until #893 lands

[PierrunoYT]

PierrunoYT pushed 8eac938 to address the remaining transactional review findings: sanitized committed provider results at both CLI call sites, consistent credential backends in tests, cross-platform lock permission/contention handling, reported rollback and plaintext-migration failures, direct destination-key writes on rename, and lock-held OAuth ownership validation plus atomic token persistence across CLI/TUI browser, device, and ChatGPT flows.

Validation passed: focused race tests for config/oauth/cli/tui, formatting, vet, full tests, release build and smoke, static analysis, Windows config test cross-compilation, and diff hygiene. make vulncheck continues to report the known dependency findings GO-2026-6222 (golang.org/x/image@v0.44.0, fixed in v0.45.0) and GO-2026-6115 (github.com/ledongthuc/pdf, no fixed release).

[PierrunoYT]

PierrunoYT pushed 8eac938b461acdcb52845fab44b903cafaf8ae9e to close the remaining transactional provider review findings.

Highlights:

• hold the provider transaction boundary across OAuth ownership validation and token persistence
• propagate rollback and credential-store acquisition failures
• correct cross-platform lock contention semantics and pin test credential backends
• preserve failed plaintext migrations with redacted aggregate errors
• strengthen destination-identity and ambiguous catalog-ID coverage

Validation passed: focused race tests, formatting, vet, full tests, release build, smoke, static lint (0 issues), Windows config compilation, and diff hygiene. make vulncheck still reports known GO-2026-6222 (golang.org/x/image@v0.44.0, fixed in v0.45.0) and GO-2026-6115 (github.com/ledongthuc/pdf, no fixed release) dependency findings.

This PR remains stacked behind #893 and still needs stack/base integration with current main before final review.

Document the stale-lock recovery path.

Age-based lock stealing was removed, so a process that dies between lock creation and release leaves .zero-provider-write.lock on disk forever. Every later provider mutation then fails with "provider config/key transaction is busy; retry the operation", and retrying never succeeds.

The fail-closed choice is correct. The user-facing message is not actionable for that state. Two options:

• Include the lock path in the timeout error so the user can remove it.
• Add the recovery step to zero doctor output or the troubleshooting docs.

Example for the first option:

One token-commit boundary is implemented twice. tuiOAuthTokenCommit and catalogOAuthTokenCommit are the same function: the same signature, the same blank-input guard, and the same config.CommitCatalogProviderLogin wrapper around store.Save. This is the transaction boundary for every OAuth token write, so a future change must be applied in both places or the copies drift.

• internal/cli/auth.go#L392-L405: replace catalogOAuthTokenCommit with a call to the same shared helper.

Place the helper where both packages can reach it. internal/config is the natural home because it owns CommitCatalogProviderLogin. If the resulting internal/config → internal/oauth import direction is not acceptable, put it in internal/oauth and inject the config validation callback.

[PierrunoYT]

Rebased onto current upstream/main and addressed the outstanding CodeRabbit findings in c8528ba: ambiguous mutations now assert the complete config remains unchanged; setup verification propagates stored-key read failures; permission tests skip under root; the cross-process test pins its credential backend; lock timeout errors identify the stale lock path; and CLI/TUI OAuth writes share one config-owned commit boundary. Validation passed: focused tests, gofmt, go vet ./..., go test ./..., release build/smoke, staticcheck/unused/ineffassign, govulncheck, and diff hygiene. The targeted -race command could not run on this Windows host because CGO is disabled; CI provides the platform coverage.

Make lock release atomic with ownership validation.

Lines 275-283 read the token and then remove the lock by pathname. Another process can replace the lock after the read and before lockutil.RemoveLockFile.

This release can delete the new holder's lock. Two provider transactions can then write configuration and credentials concurrently.

Use a lock primitive that couples ownership validation with release. Do not fix this with another pathname check.

As per coding guidelines: “Fail closed on ownership, lease, and permission checks.”

[Vasanthdev2004]

The transaction is still good and I still could not break it. The divergence I asked about is answered. The stack item is what keeps this blocked, and it now has teeth rather than being a tidiness complaint.

The divergence is deliberate, and you wrote the reason down. runProviderProfileOperation's doc block says removal and repair pass allowInvalidInput=true "because refusing to delete a row from a config the user cannot otherwise fix is a deadlock". That is the right rule and it is the answer I was after: it is a decision, not a side effect of the rewrite. Good.

But the deadlock has moved rather than gone, and it is live on this head. Same fixture as before, an unnamed row plus a case-duplicate pair. Built this head and ran the chain:

$ zero providers remove groq
Removed provider groq / Active provider: Groq

$ zero providers repair-config
[zero] duplicate persisted provider name "Groq"; remove one of the rows in config.json

$ zero providers list
[zero] persisted provider name cannot be empty; run `zero providers repair-config` to name the legacy provider

list sends the user to repair-config, and repair-config refuses citing a duplicate Groq. After the removal the file contains one row named Groq and one named "". So the error names a duplicate the config does not have, and the user has nowhere to go.

This is not your bug, which is exactly why it blocks. I built #892's current head and ran the identical chain against the identical fixture:

$ zero providers repair-config
Named legacy provider openai in ...\config.json

$ zero providers list
[zero] provider Groq requires model — add "model" to its entry in config.json, or re-run: zero setup <catalog-id> --model <model>

It repairs, and list then gives an error a user can actually act on. So #892 already fixes this and #894 is one commit short of inheriting the fix. Shipping this head without restacking ships a deadlock that is fixed one PR upstream.

On the ordering itself. I stopped asking for a rebase in the abstract and measured it. There is no order that works today:

892 then 893  CONFLICT  internal/cli/auth.go, auth_test.go
893 then 892  CONFLICT  internal/cli/auth.go, auth_test.go
892 then 895  CONFLICT  app_test.go, auth.go, auth_test.go
895 then 892  CONFLICT  internal/cli/app_test.go

893 is contained in 894 is contained in 895 by file set, so those three are cumulative. 892 is not in that chain: 40 files touched by both 892 and 893, 20 of them differing, and five files exist only on 892 (including internal/config/provider_ownership.go and internal/cli/completions.go) that are absent from all three of the others.

Rebase 893 onto 892, 894 onto 893, 895 onto 894 and I will do a proper pass over the series in order. Or tell us 892 is superseded and the other three carry its work, and I will review on that basis instead. Either answer is fine; the current shape is the one that cannot land.

Nothing else from me. Build and vet clean on this head, internal/config, internal/oauth, internal/credstore and internal/tui all green, and CI is green. #893's blocker is fixed and I have approved it.

[PierrunoYT]

Restacked this branch onto the updated #893 head (542c223). The history is now #892 → #893 → #894, as requested. The PR base remains main while the lower fork branches await landing.

The rebase conflicts were all at the provider transaction boundary. I preserved the lower stack's newer provider-row ownership, legacy catalog adoption, composable unnamed-row repair, and project/environment row handling while applying this PR's serialized config/credential writes around those behaviors.

Integration commit 2ed0de1 specifically carries #893's three-state catalog ownership model through CommitCatalogProviderKey, so a legacy catalog-named row is adopted inside the same key transaction rather than treated as a new provider. It also updates the concurrent repair regression for the stacked return contract.

Local validation (Go 1.26.6):

• make fmt-check
• go vet ./...
• go test ./...
• go test -race ./internal/config
• go run ./cmd/zero-release build
• go run ./cmd/zero-release smoke
• make lint-static — 0 issues
• make vulncheck — no vulnerabilities
• git diff HEAD --check

@Vasanthdev2004 #894 is ready for another look once refreshed CI completes.

readCLIConfigFixture decodes config.FileConfig from a path, which is what readFileConfig in internal/cli/command_center_test.go already does for the same package.

Document the partial-success return.

On a per-profile setKey failure this function keeps going, records the failure in skipped, and still publishes when migrated > 0. It therefore returns a non-zero count together with a non-nil error. That combination is easy to mishandle at the call site: a caller that returns early on err != nil will report the migration as failed while some keys did move and config.json was rewritten. State the contract on the function.

The duplicate work/WORK rows add no coverage here.

ValidatePersistedProviderNames scans providers in order and returns on the first problem. The first row has an empty name, so the empty-name error wins and the case-duplicate branch is never reached. The assertion at Line 507 matches the empty-name message, which names zero providers repair-config.

Split this into two cases, or drop the unreachable rows, so each validation branch is asserted on its own.

kept := saved[:0] compacts in place. Every earlier holder of that slice — the picker snapshot the new syncSavedProviderModel comment at Lines 812-814 explicitly protects against — then sees shifted rows and a duplicated tail element.

The comment contradicts the test name and the assertions.

The comment says an unrelated ambiguous pair "must not suppress deleting every credential for the unambiguous profile" and that "only the final marker-write should fail". The test name says RejectsUnrelatedAmbiguousConfigBeforeCredentialDeletion, and the assertions at Lines 1122-1127 require the OAuth token and the API key to still be present. The documented behavior is the opposite of the pinned behavior.

Rewrite the comment to describe the retained contract: an unrelated ambiguity is rejected before any credential deletion.

Pin the credential backend in this test.

config.ProviderKeyStoreAt(dir) calls credstore.New without ZERO_CRED_STORAGE. On macOS with an available keyring, credstore.New selects the keyring backend, which ignores Dir. store.Set("work", "sk-lower") then writes to the real login keychain, and the exact-name removal at Line 239 reaches op.deleteKey and deletes from it.

Every sibling test that touches the store pins the backend, including Line 679 and Line 788 in this file.

Redact configuration errors before displaying them in both provider-management paths.

The removal and rename flows return errors from provider resolution, persistence, and ownership operations verbatim. These errors can include the user configuration path, while the repair path already applies redaction.ErrorMessage. Apply the same redaction before writing errors to stderr or assigning them to user-facing status fields.

Also applies to internal/tui/provider_manager.go:116-121.

In `@internal/cli/provider_onboarding.go` around lines 493 - 502, Wrap errors from
ResolvePersistedProviderName and RemoveProviderAndKey with
redaction.ErrorMessage before passing them to writeAppError, matching
runProvidersRepairConfig. Apply the same redaction to both error paths in
runProvidersRename, while preserving the existing exitCrash behavior.

Apply the same fix in `@internal/tui/provider_manager.go` around lines 116 - 121:
The manager displays ownership and removal errors without redaction.

Update the doc comment: this function now also rewrites config.json.

The comment still says ForgetProviderKey "removes a provider's stored API key from the credential store". It now delegates to DeleteProviderCredentials, which also clears every apiKeyStored marker sharing the provider's normalized identity and publishes the config. Callers reading the comment will not expect a config write.

📝 Proposed doc change

-// ForgetProviderKey removes a provider's stored API key from the credential store,
-// reporting whether one existed. Used by the lifecycle "remove key" / auth logout.
+// ForgetProviderKey deletes a provider's stored API key and clears every
+// apiKeyStored marker sharing its credential identity, in one transaction
+// against the default user config. It reports whether a credential existed.

Prevent duplicate in-memory profiles for adoptable rows. EnsureCatalogProvider adopts a saved profile with an empty CatalogID when its Name matches the catalog identity. appendOAuthLoginProfile checks only CatalogID, so it appends a second entry to m.savedProviders; the provider manager and picker render both entries. Add the empty-CatalogID adoption guard, using config.SameProviderIdentity for the name comparison.

Restacked this transaction layer onto the CodeRabbit fixes in #893. The conflict resolution preserves DeleteProviderCredentials / DeleteResolvedProviderCredentials transaction semantics while carrying forward the config-adjacent store, legacy adoption, ownership, and diagnostic fixes. New head: 4502b9b. Targeted config/CLI/TUI tests pass; full-stack validation was run on dependent PR #895.
