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.

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) {
+	t.Setenv("ZERO_CRED_STORAGE", "encrypted-file")
 	storePath := withAuthStore(t)
 func TestRunAuthLogoutDeletesCatalogIDToken(t *testing.T) {

 	storePath := withAuthStore(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.

Add a case with two profiles sharing catalogId: "acme", address it as acme, and assert a non-zero exit with both profiles still present.

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
 	}
-	store, _ := op.credentialStore()
+	store, err := op.credentialStore()
+	if err != nil {

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.

780-822: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value

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 {
 			profile := &op.config.Providers[index]
 			key := strings.TrimSpace(profile.APIKey)
 			if key == "" || strings.TrimSpace(profile.Name) == "" {
 				continue
 			}
 			if err := op.setKey(profile.Name, key); err != nil {
+				// Leave the plaintext key untouched; a failed Set must not strand it.
+				skipped = errors.Join(skipped, fmt.Errorf("migrate stored key for %q: %w", profile.Name, err))
 				continue
 			}

Do not put the key value in the error text.

Review on Twigpine#892 asked for the config/key transaction to stay in Twigpine#894 so
this PR keeps to the provider identity boundary it declares.

Revert the CommitProviderProfile/lockProviderWrite implementation and
restore the PreflightProviderWrite + UpsertProvider callers in the add,
setup, onboarding, wizard, and manager paths. Twigpine#894 owns the single
authoritative transaction over the full writer inventory.

Keep the Unicode credential-identity fix, which is identity scope: match
saved providers with credstore.NormalizeProvider instead of
strings.EqualFold. EqualFold folds "s" and long-s "\u017f" together while
the credential store keeps separate entries, so a lookup could return a
different provider's profile and reach its secret.

Addresses the failing macOS smoke check and the CodeRabbit findings on Twigpine#894.

TestCommitProviderProfileCrossProcessCaseVariantsKeepOneKey gave both
children ZERO_CRED_STORAGE=encrypted-file but left the parent on auto
resolution, which is the keychain on macOS. The parent then read a
different backend than the children wrote and reported
`committed key = "" ok=false err=<nil>`. Linux CI passed because auto
resolves to encrypted-file there. Pin the backend in the parent, as every
sibling test in the file already does; this also stops the test from
reaching a developer's real keychain.

Resolve a sole nameless provider row instead of failing closed. With one
unnamed provider and no activeProvider, activeName stayed empty and
selection was skipped, so resolution returned ErrNoActiveProvider even
though normalization names that row "openai". Default activeName to the
openai identity the row will carry, and cover it with a regression test.

Propagate the committed stored-key state to the local profile in
`providers add` and setup so output surfaces report APIKeyStored
correctly. The plaintext key intentionally stays in memory: it is this
run's only copy for the verification probe, and the JSON snapshot redacts
it. Document that ProviderEdit.Description is applied verbatim while the
other fields treat empty as "unchanged".

Addresses the review tail on Twigpine#892. Both code findings shared one root
cause: live session state and the savedProviders mirror were updated by
different rules at different call sites, with no single reconciliation
policy after a mutation.

Two predicates now own that, instead of spot fixes:

- syncSavedProviderModel is the one place a persisted model change is
  mirrored into savedProviders. The manager's rows and the picker's
  model sections are built from that list, not from the live profile,
  so switchProviderModel and handleModelCommand both updated the client
  and config.json while /providers kept showing the previous model
  until restart. persistSelectedModel now returns the exact row it
  wrote so its caller mirrors onto that row rather than re-deriving it
  from the session's spelling.

- sessionRowName answers "is this the provider I am running on?", a
  third question distinct from credential identity and from exact
  row-targeting. An exact spelling wins, so case-variant siblings and
  s/long-s stay distinct; only an identity carried by exactly one row
  resolves to that row's own spelling. That fixes a sole row the
  session spells differently (ZERO_PROVIDER=openai against a saved
  OpenAI) missing the active marker, the rename ZERO_PROVIDER sync, and
  the delete/edit notes. reloadProviderManagerRows resolves once so
  render and sync share one value.

TestProviderManagerCaseVariantEditDoesNotChangeLiveSibling is split:
its fixture held a single row, so it was the sole-row case rather than
the sibling case its name claimed, and now asserts the sync. The real
sibling guard moves to a two-row delete fixture — edit cannot exercise
it because EditProvider rejects a duplicate-identity config first.

Also documents scope rather than widening it: the ambiguous-config
rejection now names `zero providers remove <exact>` as the repair path,
since that rejection blocks interactive startup for configs that
worked before, and every fail-soft SecureProviderProfile capture site
says that atomic capture+publish is Twigpine#894.

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).

This stacked PR still depends on #893 and must be integrated with current main before review; no merge or review resolution was performed.

Review on Twigpine#892 asked for the config/key transaction to stay in Twigpine#894 so
this PR keeps to the provider identity boundary it declares.

Revert the CommitProviderProfile/lockProviderWrite implementation and
restore the PreflightProviderWrite + UpsertProvider callers in the add,
setup, onboarding, wizard, and manager paths. Twigpine#894 owns the single
authoritative transaction over the full writer inventory.

Keep the Unicode credential-identity fix, which is identity scope: match
saved providers with credstore.NormalizeProvider instead of
strings.EqualFold. EqualFold folds "s" and long-s "\u017f" together while
the credential store keeps separate entries, so a lookup could return a
different provider's profile and reach its secret.

Addresses the review tail on Twigpine#892. Both code findings shared one root
cause: live session state and the savedProviders mirror were updated by
different rules at different call sites, with no single reconciliation
policy after a mutation.

Two predicates now own that, instead of spot fixes:

- syncSavedProviderModel is the one place a persisted model change is
  mirrored into savedProviders. The manager's rows and the picker's
  model sections are built from that list, not from the live profile,
  so switchProviderModel and handleModelCommand both updated the client
  and config.json while /providers kept showing the previous model
  until restart. persistSelectedModel now returns the exact row it
  wrote so its caller mirrors onto that row rather than re-deriving it
  from the session's spelling.

- sessionRowName answers "is this the provider I am running on?", a
  third question distinct from credential identity and from exact
  row-targeting. An exact spelling wins, so case-variant siblings and
  s/long-s stay distinct; only an identity carried by exactly one row
  resolves to that row's own spelling. That fixes a sole row the
  session spells differently (ZERO_PROVIDER=openai against a saved
  OpenAI) missing the active marker, the rename ZERO_PROVIDER sync, and
  the delete/edit notes. reloadProviderManagerRows resolves once so
  render and sync share one value.

TestProviderManagerCaseVariantEditDoesNotChangeLiveSibling is split:
its fixture held a single row, so it was the sole-row case rather than
the sibling case its name claimed, and now asserts the sync. The real
sibling guard moves to a two-row delete fixture — edit cannot exercise
it because EditProvider rejects a duplicate-identity config first.

Also documents scope rather than widening it: the ambiguous-config
rejection now names `zero providers remove <exact>` as the repair path,
since that rejection blocks interactive startup for configs that
worked before, and every fail-soft SecureProviderProfile capture site
says that atomic capture+publish is Twigpine#894.

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

Highlights:

  • use sanitized committed.Persisted results at both CLI commit sites
  • 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.

242-293: 🩺 Stability & Availability | 🔵 Trivial

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:

🛠️ Proposed message change
 		if time.Now().After(deadline) {
-			return nil, fmt.Errorf("provider config/key transaction is busy; retry the operation")
+			return nil, fmt.Errorf("provider config/key transaction is busy; retry the operation (if no other zero process is running, remove the stale lock file %s)", lockPath)
 		}

87-96: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

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.

Addresses the failing macOS smoke check and the CodeRabbit findings on Twigpine#894.

TestCommitProviderProfileCrossProcessCaseVariantsKeepOneKey gave both
children ZERO_CRED_STORAGE=encrypted-file but left the parent on auto
resolution, which is the keychain on macOS. The parent then read a
different backend than the children wrote and reported
`committed key = "" ok=false err=<nil>`. Linux CI passed because auto
resolves to encrypted-file there. Pin the backend in the parent, as every
sibling test in the file already does; this also stops the test from
reaching a developer's real keychain.

Resolve a sole nameless provider row instead of failing closed. With one
unnamed provider and no activeProvider, activeName stayed empty and
selection was skipped, so resolution returned ErrNoActiveProvider even
though normalization names that row "openai". Default activeName to the
openai identity the row will carry, and cover it with a regression test.

Propagate the committed stored-key state to the local profile in
`providers add` and setup so output surfaces report APIKeyStored
correctly. The plaintext key intentionally stays in memory: it is this
run's only copy for the verification probe, and the JSON snapshot redacts
it. Document that ProviderEdit.Description is applied verbatim while the
other fields treat empty as "unchanged".

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.”

Re-reviewed at 2498717f. This now carries #892's and #893's heads, and unlike the rest of the stack it has real changes of its own since ccf06307. Those are good. It is blocked only by what it carries.

What is new here, and holds. RemoveProviderAndKey now resolves the persisted identity inside the transaction and returns the spelling it removed, so a concurrent profile write cannot retarget a removal between the lookup and the delete. TestRemoveProviderAndKeySerializesIdentityResolutionAndReassignment parks the removal on the lock seam and shows the case-variant commit waiting behind it. Going back to an exact-spelling match inside the transaction fails that test, the ambiguous-duplicate test, and the case-variant legs in both the config and cli matrices. The CLI still does its project-row ownership check before entering the transaction, and the only two production callers are the CLI and the manager, which passes the exact persisted name, so nothing gains a looser match than it had.

The manager delete is now one synchronous transaction with the marker reconcile from dff3fbf0 applied when the key really went, rather than in the follow-up command. Dropping that call fails the successful-removal leg of TestProviderManagerDeleteReconcilesStoredKeyMarkers on both the live and the saved marker.

The redaction wrappers are pinned as well. Printing the raw transaction error from providers remove or providers rename fails TestProviderMutationsRedactStoredKeyFailures with the key-shaped directory name in stderr, and doing the same in the manager fails the delete leg of TestProviderManagerMutationErrorsRedactConfigPathAndPreserveState.

The RepairUnnamedProvider resolution keeps this branch's transactional shape and carries #892's ownership logic into it: legacyName from the merge, unnamedWasActive, the stored-key identity refusal, and the default name only on the bare form. #892's repair tests pass against it.

What blocks it is the resume block from #892's f187303a, which this head contains. Details are on #892. Once that settles and the stack is refreshed onto it, I expect to approve this on the delta alone.

CI is 9 of 9 at head. config, cli, credstore, oauth and provideroauth pass natively here, tui apart from the transcript-scroll test that fails on main on this box too.

Address PR Twigpine#892 review feedback: resume retains the live client identity and model, stored-key case collisions explain manual recovery, and persistence errors appear only once.

Regression tests fail on the reviewed implementation and pass with these changes. Full tests, focused config/CLI/TUI race tests, vet, formatting, release build/smoke, and vulnerability checks pass. Static lint reports four existing suggestions in unchanged files.

Resume restores session history without switching the live client. Keep the retained provider identity and model aligned with that client, and assert the endpoint, credential, client, and resume summary in the regression test.

Apply the shared ownership guard before providers use resolves a saved alias, and check normalized concrete names for remove and rename as well.

Cover project and environment rows, exact and normalized requests, text and JSON responses, unchanged config and credentials on rejection, and exact saved-row addressing.

Re-reviewed at 639ac5ba. The resume fix here holds: putting the block back fails the different-session leg of TestResumeAfterDeletingLiveProjectRow, and dropping the empty-provider clear fails TestResumeHonorsPriorCompaction. Nothing else in this PR's own delta changed since my last pass, and that part I'm happy with.

It is still blocked only by what it carries, but that is now the other way round. This fix is a separate copy of #892's 83fa9ebe, and this head doesn't have #893's new 808af63d. With #893's TestProviderCommandsRejectConcreteCatalogAlias applied here, it fails 16 of its legs, so this head still resolves a catalog alias ahead of a concrete row. The details and the refresh order are in my review on #893. Once the stack is refreshed, I expect to approve this on the delta alone.

CI is 9 of 9 at head.

Retain the reviewed resume implementation and port the unnamed stored-credential collision guard into the provider transaction boundary.

Re-reviewed at bab8db71, now on #893's head. The refresh conflicted in three files, and each resolution keeps one copy of every fix. The resume test and its comment come from below, and RepairUnnamedProvider keeps this PR's transaction with #893's stored-credential sibling check inside it. That check is load-bearing: taking it out fails TestRepairUnnamedStoredProviderCaseCollisionExplainsManualRecovery. #893's TestProviderCommandsRejectConcreteCatalogAlias is in the branch now and passes all 36 legs. internal/cli, internal/config and internal/tui pass here, and CI is 9 of 9 at head. Approving on the delta, as I said I would.

The transaction itself is right: cross-process lock (flock / LockFileEx fail-immediate) on a 0600 lock file with a bounded 5s wait, age-based stealing removed so conflicts fail closed, release bound to file-handle ownership (no unlink race), consistent lock ordering, read-validate-mutate under the lock, temp-plus-rename publishing at 0600, and rollback only when the stored credential still exactly matches what this transaction wrote. Three gaps: the writeProviderNameRepair doc comment says it rewrites only the changed fields but the code restates the whole file with MarshalIndent (a comment-code mismatch against the repo's honesty rule); its writeConfigData predates #1093 so there is no fsync of file or directory after rename, meaning a crash right after a reported commit can lose the transaction (and it textually conflicts with #1093 and #1001 in writer.go); and CommitProviderProfile returns a partial result alongside the error when providers exist.

Pin both the file backend and temporary token path on every new manager and ownership fixture that executes OAuth cleanup. An inherited keyring backend must not bypass test-owned paths.

Validation: full go test ./..., focused TUI race tests, fmt-check, vet, release build/smoke, vulncheck, and diff hygiene pass. Temporary NewStore boundary probes fail all five original paths and pass each fixed path. Advisory lint reports four unchanged findings outside this patch.

Preserve the transaction-layer no-double-delete cleanup regression while applying the predecessor OAuth backend and temporary-path isolation.

Validated with full tests, affected package race tests, inherited-keyring TUI regressions, formatting, vet, release build/smoke, vulnerability checks, and diff hygiene. Advisory lint retains four unrelated existing findings.

Describe whole-document repair publication accurately and document committed results on lock release errors. Strengthen publication-failure coverage with an existing provider row, zero result, unchanged config, and restored credential assertions. Removing the zero-result guard fails the targeted regression.

Re-reviewed at 78f08f60, which merges #893's new commit and adds one of its own. The two doc comments now say what the code does, and the publication-failure test pins the zero result and an unchanged config. Dropping the len(cfg.Providers) == 0 guard fails it, with a committed result returned for a rejected publication. internal/config and the TUI provider tests pass natively on Windows. The latest CI run is 9 of 9; the cancelled checks beside it are a duplicate run on the same commit. Approving.
