Summary

This is PR 1 of a 4-PR split of #725, opened in response to review feedback that the combined branch changed four distinct contracts at once and could not be reviewed against a stable baseline.

It defines the provider identity contract and wires every consumer boundary it touches onto that contract, so no caller is left on the old mental model. It does not implement cross-process locking or the full writer-inventory transaction — that stays with #894.

Note

#893 (2/4) is stacked on this PR and should merge after it.

The contract

Persisted provider rows and credential-store entries answer two different questions, and mixing them let one profile's mutation reach another profile's row and secret.

  • Credential identitycredstore.NormalizeProvider (trim + ToLower), exposed as config.SameProviderIdentity. Callers deciding whether two spellings share one stored secret use it rather than strings.EqualFold: Unicode case folding equates s and ſ while strings.ToLower does not, so an EqualFold comparison can promise a survivor access to a key it can never look up.
  • Exact row identity — trimmed provider.Name equality, used by every row-targeting mutator (MarkProviderAPIKeyStored, ProviderPersisted's mutating callers, SetProviderModel, ClearProviderKeyStored, RemoveProvider, and the oldName lookups in RenameProvider/EditProvider).
  • Publication validationValidatePersistedProviderNames rejects persisted rows repeating a folded identity, whether the spellings are identical or only case variants. writeConfigFile guards every write with it, and Resolve() validates user config before merging.

The four shared helpers (the "front door")

Defining two rules is not enough — every boundary that gated on one rule and mutated with the other needed one place to cross between them:

Helper What it owns
ResolvePersistedProviderName(path, input) User/session spelling → the exact persisted row. Exact wins, credential identity is a fallback, an identity matching 2+ rows is an error, not an arbitrary pick. SetActiveProvider's loop was extracted into it rather than copied a fourth time.
CredentialKeyRetained(providers, removedName) Retention by ownership, not name survival: keep the shared secret only when a remaining row has APIKeyStored. A markerless case variant can no longer orphan a key ApplyStoredAPIKey will never read. ProviderKeyRetainedAfterRemoval(path, name) answers the same question before mutating, so confirmation copy and behavior share one predicate.
PublishProviderCredential(path, exactName, key) One operation for validate → snapshot → store.SetMarkProviderAPIKeyStored, restoring the previous stored value when publication is rejected instead of deleting the shared entry.
applyProviderKeyRemovalToSession(name) (TUI) Reconciles savedProviders / providerProfile with a disk key removal, so the session cannot claim a key that is gone until restart.

Consumer boundaries wired onto it

  • auth openrouter — preflights before EnsureCatalogProvider's case-insensitive lookup, then publishes through PublishProviderCredential. A legacy openrouter/OPENROUTER config no longer costs the user their working key, and a login that could not be persisted now exits non-zero while still printing the minted key for manual use.
  • auth logout — clears the marker before deleting the secret, and both halves address the store beside the config being edited rather than one using the default-path store.
  • providers remove / providers rename — resolve the user's spelling to the exact row between the ProviderPersisted gate and the mutator, so zero providers remove work against a sole WORK row works instead of failing "not found"; an ambiguous duplicate config errors before anything is touched.
  • TUI provider manager — delete and edit resolve the row spelling; retention uses CredentialKeyRetained; the delete confirmation text is computed from ProviderKeyRetainedAfterRemoval so it cannot promise a key removal the delete will not perform.
  • TUI wizard manage-key remove — marker first, secret second, then session reconciliation.
  • Model persistenceswitchProviderModel persists with the spelling SetActiveProvider resolved, and persistSelectedModel resolves before writing; write failures on a persisted row are surfaced instead of dropped into _, _ =.
  • EqualFold audit — every provider-name comparison in auth.go, picker.go, provider_wizard.go, provider_wizard_discovery.go, session.go, and EnsureCatalogProvider was classified by intent and moved to either exact row spelling or SameProviderIdentity.

activeProvider repair

Repairing a case-duplicate config could strand activeProvider on a third spelling (WoRk with rows work/WORK) that matches no remaining row exactly, blocking every exact mutator. RemoveProvider now re-points it at the survivor's own spelling when exactly one row carries the identity.

Live-session reconciliation

Three spellings exist, not two: credential identity, the persisted row's exact name, and the live session's name (m.providerName, ZERO_PROVIDER, resumed session metadata), which may differ from disk. The session spelling gets its own predicate rather than reusing either config-level rule:

  • sessionRowName(live, providers) resolves the live spelling to the row it refers to. An exact spelling wins — so case-variant siblings (work vs WORK) and s/ſ stay distinct, and a session never follows a mutation aimed at its sibling — and only a credential identity carried by exactly one row resolves to that row's own spelling. Anything else falls back to exact equality rather than guessing, which keeps env-derived and ambiguous cases out. It feeds the manager's ● active marker, the rename ZERO_PROVIDER sync, the delete "keeps running" note, and the edit restart note. reloadProviderManagerRows resolves once into manageActiveName so render and sync share one value.
  • syncSavedProviderModel is the single reconciliation point for a persisted model change. The manager's rows and the picker's model sections read savedProviders, not the live profile, so switchProviderModel and handleModelCommand (via persistSelectedModel, which now returns the exact row it wrote) both mirror the write into that list — otherwise /providers kept showing the previous model until restart.

Legacy case-duplicate configs are rejected at read time

ValidatePersistedProviderNames runs on user-config load, so a pre-existing config with rows differing only by case (work + WORK) now fails Resolve(). Interactive zero, TUI startup, auth logout, and wizard key removal all refuse to run until it is repaired. This is intentional — ambiguous configs are rejected rather than silently coalesced — but it is a user-visible behavior change for configs that worked before this PR, so it needs a release note.

Repair path: zero providers remove WORK (the exact row spelling). RemoveProvider reads config.json directly instead of going through Resolve, so it still works while everything else refuses to start; hand-editing config.json works too. Rename/edit cannot shrink a duplicate — those mutators validate before mutating. The rejection message now names that command instead of only describing the problem.

A guided in-TUI repair or a zero providers repair-config command is a larger change than this slice; #893 is the natural home if we want one.

Scope: what #894 still owns

This PR wires boundary compatibility — preflight before capture, resolve before exact mutation, ownership-based retention, session sync, and restore-on-failure for the OpenRouter/explicit-key publication path (PublishProviderCredential: preflight → snapshot → set → publish → restore).

It does not make capture atomic everywhere. providers add, zero setup, wizard finalize, and manager edit-with-new-key still run preflight → SecureProviderProfile (store Set) → config write, with documented fail-soft on store errors and no rollback if the config write fails after a successful capture. Preflight removes the validation-failure-after-capture case; what remains is a rare write failure (permissions, disk full) leaving a store entry without apiKeyStored — pre-merge-base behavior, not a new regression here. Each of those call sites now carries a one-line comment saying so, so the next reader does not assume OpenRouter-grade rollback already landed.

It also deliberately does not introduce cross-process locking or a single transaction spanning the full writer inventory; the premature CommitProviderProfile/lockProviderWrite implementation was reverted for that reason. #894 introduces one authoritative transaction over every config/key lifecycle mutation with its declared fail-closed lock policy, and owns atomic capture+publish for the paths listed above.

Tests

  • TestProviderIdentityMatrix (internal/cli) — one table-driven test over CLI + config writer + credstore temp dirs covering case-variant remove/rename/use, ambiguous duplicate rejection with byte-for-byte config comparison, shared-credential retention, markerless-survivor deletion, stale activeProvider repair, and s vs ſ end to end.
  • Regressions for OpenRouter key preservation on rejected publication, logout marker cleanup for a case-variant argument, delete-confirmation retention copy, wizard session sync, wizardProviderStoredKey Unicode identity, and case-variant model persistence.
  • Config-level tests for ResolvePersistedProviderName, CredentialKeyRetained, ProviderKeyRetainedAfterRemoval, and PublishProviderCredential's restore/delete rollback paths.
  • TestModelSwitchSyncsSavedProviders — a case-variant switch mirrors onto the row SetProviderModel actually wrote, leaves unrelated rows alone, and shows through providerManagerRowMeta without a restart; persistSelectedModel returns the resolved row spelling its caller mirrors with.
  • TestProviderManagerSoleRowCaseVariantTracksLiveSession — live work against a sole WORK row gets the active marker, and a rename carries onto providerName, providerProfile, and ZERO_PROVIDER.
  • TestProviderManagerCaseVariantDeleteDoesNotChangeLiveSibling — the sibling guard: rows work+WORK, live work, deleting WORK leaves the live session, its env export, and the status notes untouched.

Pre-existing tests adjusted

  • TestProviderWizardManageKeyRemoveReportsCleanupFailures/stored key deletion — now asserts the marker is cleared before the secret delete is attempted (the new ordering).
  • Three fixtures relying on case-insensitive row matching still exercise whitespace trimming: TestSetActiveProviderSwitchesConfiguredProvider, TestSetProviderModelUpdatesConfiguredProvider, TestRemoveProviderDeletesAndHandsOffActive.
  • TestProviderManagerCaseVariantEditDoesNotChangeLiveSibling was split in two. Its fixture held a single row (WORK) with live work, so it never exercised the sibling case its name claimed — it was exactly the sole-row case, and now asserts the sync as …SoleRowCaseVariantTracksLiveSession. The real sibling guard moved to a two-row delete fixture; edit cannot be used for it because EditProvider rejects a duplicate-identity config before mutating.
  • assertAmbiguousConfigUnchanged follows the rejection message now naming the repair command.

Walkthrough

Provider identity handling now uses trimmed lowercase credential-store identities while preserving exact persisted names. Configuration writes and migrations validate names before side effects. CLI and TUI provider operations preserve shared credentials and reject ambiguous or colliding names.

Merge Risk: 🔵 Low · up to 705de

The PR changes provider identity matching, persistence, and credential cleanup across CLI and TUI flows. It is mergeable with explicit owner follow-up because some failure paths can expose unredacted details or leave credential state inconsistent, while the remaining concerns are bounded and do not indicate a release-blocking correctness or availability issue.

102-148: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Collapse the two clear functions into one predicate-driven helper.

ClearProviderKeyStored and ClearProviderKeyStoredCaseVariants differ only in the name-match predicate. The read, unmarshal, loop, and write logic are identical. Extract a shared helper so a future change to the read-modify-write sequence cannot drift between the two.

♻️ Proposed refactor
+func clearProviderKeyStored(path, provider string, matches func(rowName string) bool) (bool, error) {
+	path = strings.TrimSpace(path)
+	provider = strings.TrimSpace(provider)
+	if path == "" || provider == "" {
+		return false, nil
+	}
+	data, err := os.ReadFile(path)
+	if err != nil {
+		if os.IsNotExist(err) {
+			return false, nil
+		}
+		return false, fmt.Errorf("read config %s: %w", path, err)
+	}
+	var cfg FileConfig
+	if err := json.Unmarshal(data, &cfg); err != nil {
+		return false, fmt.Errorf("invalid config JSON %s: %w", path, err)
+	}
+	changed := false
+	for index := range cfg.Providers {
+		if matches(cfg.Providers[index].Name) && cfg.Providers[index].APIKeyStored {
+			cfg.Providers[index].APIKeyStored = false
+			changed = true
+		}
+	}
+	if !changed {
+		return false, nil
+	}
+	return true, writeConfigFile(path, cfg)
+}

ClearProviderKeyStored then passes func(row string) bool { return strings.TrimSpace(row) == provider }, and ClearProviderKeyStoredCaseVariants passes a credstore.NormalizeProvider comparison.

I found issues that need to be addressed before this is ready.

This review respects the stated 1/4 split. The findings below do not ask to fold the later catalog, transaction, or UX work into this PR; they identify cases where PR1 changes a shared identity contract that existing CLI/TUI code already consumes. Each boundary needs to remain backward-compatible until its designated successor lands, or the producer and its dependent consumer need to move into the same mergeable slice.

Findings

  • [P1] Validate before storing a credential for a new provider
    internal/cli/provider_setup.go:58
    The new collision check is inside UpsertProvider, but Go evaluates SecureProviderProfile(profile, configPath) first. That helper immediately calls Store.Set, and the store canonicalizes WORK to work. Consequently, starting with a valid saved work profile holding key OLD, zero providers add ... --name WORK --api-key NEW overwrites the work secret with NEW and only then rejects the duplicate config row. The command reports failure while the existing provider has silently changed credentials. saveSetupProvider and the TUI wizard have the same capture-before-validation ordering; plaintext-key migration also writes secrets before the new write-time validator can reject an invalid file.

    The root cause is splitting one logical provider update across independently mutating config and credential-store operations, with validation occurring after the first side effect. The planned transaction work in PR3 is a suitable long-term home, but PR1 cannot expose the rejecting UpsertProvider behavior while existing callers still capture first. Either land a narrow preflight/rollback bridge with this producer change, or defer this behavior change to the transaction slice. Add regression coverage that asserts a rejected case-variant add/setup leaves both config bytes and the existing store entry unchanged.

  • [P2] Keep the shared credential when repairing a case-duplicate config
    internal/config/writer.go:401
    This new path intentionally allows RemoveProvider("WORK") to repair a legacy work/WORK config and leave the exact work row. After that successful config write, both the CLI and TUI unconditionally delete the removed name from the credential store. Because the store canonicalizes both spellings to work, cleanup deletes the survivor's shared key; its surviving apiKeyStored: true marker then causes the repaired provider to be presented as credentialed although runtime key lookup fails.

    The root cause is treating a row deletion as proof that its credential identity has no remaining owners. The planned credential-candidate work in PR2 can own the final shared-credential policy, but this PR's new repair behavior must not reach current unconditional cleanup first. Either keep the prior non-repairing behavior until that consumer changes, or add the narrow post-mutation ownership check now. Only delete when no same-identity survivor remains; otherwise retain the key and preserve the survivor's marker. Exercise the full CLI and TUI cleanup paths with a legacy duplicate and assert the remaining row can still load its key.

  • [P1] Clear the marker with the same identity used to delete the key
    internal/cli/auth.go:452
    auth logout WORK calls ForgetProviderKey, whose credential-store deletion canonicalizes the argument to work, then calls the newly exact-only ClearProviderKeyStored(configPath, "WORK"). A normal config row named work is not matched, so its secret is removed while apiKeyStored stays true. This is a regression from the base implementation's EqualFold cleanup: subsequent status/selection logic sees a configured credential, while ApplyStoredAPIKey cannot load one. The TUI's key-removal flow has the same mismatch, and the new ClearProviderKeyStoredCaseVariants helper is unused.

    The root cause is one lifecycle operation using two different identity relations: normalized identity for secret deletion and exact spelling for marker cleanup. The summary assigns logout/API-key cleanup migration to PR2, so PR1 should preserve the old compatible clearer until PR2 switches both halves of the lifecycle together—or move this exact-match change with that PR2 consumer work. The final operation should either clear every marker that refers to the removed credential or reject an ambiguous request before deleting anything. Add logout and TUI regressions for a mixed-case saved row and verify that no stale marker remains.

  • [P1] Stop using Unicode case folding for live provider identity
    internal/tui/provider_manager.go:634
    The new contract deliberately permits s and Unicode long-s (ſ) as distinct credential identities because strings.ToLower keeps their store keys distinct. The provider manager still uses strings.EqualFold, which equates them. If the session runs ſ and the user edits non-active s, the config edit targets the correct exact row, but the subsequent live-session sync treats it as the active provider and rewrites m.providerName, m.providerProfile.Name, and ZERO_PROVIDER to the edited name. The manager's in-memory edit/remove helpers use the same incompatible comparison.

    The root cause is leaving a second provider-identity implementation at a consumer boundary after defining the credential store as the authority. The summary assigns TUI synchronization to PR4, so this does not require absorbing that UX work here: PR1 can instead avoid making the distinct s/ſ state reachable by current TUI consumers until PR4, or move the minimal comparison fixes alongside this contract change. Audit provider-name comparisons by intent: use exact persisted spelling to address a row, and config.SameProviderIdentity only when reasoning about a shared credential. Add a live-session test covering active ſ plus an edit/remove of s.

  • [P2] Do not turn a case-variant providers use request into a successful no-op
    internal/cli/provider_onboarding.go:63
    ProviderPersisted now returns false unless the input spelling exactly matches the saved row. The fallback added for environment-derived providers is unchanged and uses strings.EqualFold. For a saved OpenAI row, zero providers use openai therefore concludes it is not persisted, finds the row in the resolved list case-insensitively, prints the environment-provider explanation, and exits successfully without calling SetActiveProvider or changing config. Before this PR, the same command selected the saved row.

    The root cause is the CLI's classification path applying a broader matching rule than the mutation path. The summary assigns provider-selection UX to PR4, so retain the previous compatible lookup until that slice updates the classification and mutation paths together, or include only the small bridge that prevents this false-success result now. Do not use EqualFold as a proxy for credential identity here, since it also incorrectly conflates the Unicode identities this PR explicitly preserves. Add CLI tests for exact, case-variant, environment-derived, and s/ſ inputs.

  • [P2] Validate implicit provider names before accepting persisted identities
    internal/config/writer.go:26
    The validator indexes the trimmed raw name, so an empty name and openai are accepted as different identities. Later, normalizeProvider supplies openai for an empty name and the merge path uses the same effective name. A persisted file containing both rows therefore passes the new invariant while resolving to one semantic provider—the exact resolver coalescing/ambiguous-ownership situation the validator says it prevents.

    The root cause is validating raw serialization names rather than the names the resolver and credential lifecycle actually use. Either reject blank persisted provider names at the file boundary or canonicalize each name with the same effective-name rule before duplicate detection. Include a persisted {name:""} plus {name:"openai"} regression test and ensure the error is raised before any credential migration or config rewrite.

Addressed the latest review in 50bca0a.

  • Preflight provider writes before CLI/setup/TUI credential capture, and validate before plaintext-key migration.
  • Preserve shared credentials when repairing legacy case-duplicate rows.
  • Clear stored-key markers using credential identity for logout and TUI key removal, while failing closed on ambiguous configs.
  • Replace provider-name EqualFold comparisons at the affected CLI/TUI boundaries with exact row matching or config.SameProviderIdentity as appropriate.
  • Restore case-variant providers use behavior without conflating s and ſ.
  • Reject blank persisted provider names before implicit openai normalization.
  • Added regression coverage for CLI, TUI, resolver, migration, and credential-store paths.

Validation: focused regressions, affected package suites, go vet ./..., go test ./..., release build, release smoke, govulncheck, and git diff HEAD --check passed. make is unavailable on this Windows workstation; advisory static lint still reports the unrelated pre-existing ST1005 finding in internal/peermsg/private_dir_windows.go:107.

Addressed all latest CodeRabbit findings in 70773eae.

  • Extended ambiguous-logout coverage to preserve OAuth credentials as well as API keys.
  • Removed secret-bearing values from credential migration test failures.
  • Switched TUI live-provider updates and restart messaging to exact trimmed persisted-name matching, with case-variant edit/delete regressions.
  • Made provider deletion text accurately describe conditional shared-key retention.
  • Surfaced stored-key deletion and marker-cleanup failures in the provider wizard, kept the wizard open, redacted errors, and added injected failure-path tests.

Validation:

  • focused CodeRabbit regression tests
  • go vet ./...
  • go test ./...
  • go run ./cmd/zero-release build
  • go run ./cmd/zero-release smoke
  • go run golang.org/x/vuln/cmd/govulncheck@v1.3.0 ./...
  • git diff HEAD --check
  • changed files are gofmt-clean

make is unavailable on this Windows workstation. The pinned advisory static lint still reports only the unrelated pre-existing ST1005 finding at internal/peermsg/private_dir_windows.go:107.

I found issues that need to be addressed before this is ready.

Findings

  • [P1] Preserve the existing OpenRouter key when validation rejects the config
    internal/cli/auth.go:134
    saveOpenRouterProviderKey writes the newly minted key before validation. For a legacy config containing openrouter and OPENROUTER, EnsureCatalogProvider returns an existing row without applying the new persisted-name validation, so store.Set overwrites their shared normalized credential. MarkProviderAPIKeyStored then rejects the duplicate names, and its error path deletes that normalized entry instead of restoring the previous value. The command reports a failed login, but the invalid config remains and both profiles have lost the previously working API key.

    The root cause is splitting one logical credential update into an unvalidated config lookup, a destructive store write, and a later validating config mutation. Validate the complete persisted config before any credential side effect; longer term, make the key replacement and marker publication one transaction that records and restores the prior store value if publication fails. Add a regression with a legacy duplicate config and an existing key that proves the config bytes and original credential survive rejection.

  • [P1] Do not use Unicode case folding to choose a saved provider
    internal/tui/model.go:4469
    This PR deliberately permits s and Unicode long-s ſ as separate credential identities, but the model-picker branch still uses strings.EqualFold. With s active and a picker item owned by ſ, EqualFold treats the owner as already active and runs handleModelCommand against s rather than switching to ſ. When it does need a switch, savedProviderByName in command_center.go has the same comparison and can return the first s row for a request for ſ. A user selecting a model for one provider can therefore send requests using the other provider's endpoint and credential.

    The root cause is that the new identity authority was applied to some manager paths but not to all ownership and lookup boundaries. Audit this flow by intent: select persisted rows by exact trimmed spelling, and compare credential identities with config.SameProviderIdentity, never strings.EqualFold. Add a picker/recent-model regression with saved s and ſ profiles that verifies selecting either one builds and persists the intended profile.

  • [P1] Serialize validation, credential capture, and config publication
    internal/cli/provider_setup.go:56
    The new preflight is a check-then-use sequence. Process A can preflight WORK while no profile exists; process B can then create work with key B; A next calls SecureProviderProfile, which normalizes both spellings and overwrites B's credential with key A. A's later UpsertProvider sees B's row and correctly rejects the case collision, but the surviving work profile is now silently associated with A's key. The same sequence exists in setup and the TUI wizard.

    The root cause is treating validation, credential-store mutation, and config publication as separate operations while the store and config share the same provider identity. Put the whole read/validate/capture/publish sequence behind one provider-config transaction or lock, revalidate under that lock immediately before mutation, and roll back only the write owned by the failed operation. Exercise two concurrent case-variant setup attempts and assert that the rejected attempt cannot alter the winning profile or its key.

  • [P2] Delete the key unless a surviving row actually references it
    internal/cli/provider_onboarding.go:479
    The new survivor check retains the stored key whenever a same-identity row remains, even when that row has apiKeyStored: false. Repairing a legacy config such as {work: apiKeyStored:true, WORK: apiKeyStored:false} by removing work leaves only WORK, but ApplyStoredAPIKey will not read the retained secret because its marker is false. The credential is therefore orphaned even though the user removed the only profile that referenced it. The provider-manager path duplicates the same predicate.

    The root cause is using name equivalence as a proxy for credential ownership. Preserve a shared key only when at least one remaining same-identity profile has APIKeyStored; otherwise delete it. Centralize that ownership predicate so the CLI and TUI cleanup paths cannot drift, and add coverage for both the marker-sharing and markerless-survivor repair cases.

Addressed jatmn's latest review findings in commit 8e9823b7 and pushed the fixes to this PR branch:

  • Added a serialized provider config/key commit boundary covering validation, credential capture, and config publication, with ownership-checked credential rollback. Provider add, setup, and the TUI wizard now use it; a concurrent work/WORK regression verifies the rejected writer cannot alter the winner's row or key.
  • OpenRouter persistence now validates the complete persisted config before touching the credential store and restores the previous key if marker publication fails. Added a legacy duplicate regression asserting unchanged config bytes and preserved credentials.
  • Centralized the survivor predicate as config.ProviderCredentialSurvives; a key is retained only when a remaining same-identity row has APIKeyStored. CLI and TUI removal paths use the same predicate, with marker-sharing and markerless coverage.
  • Replaced Unicode EqualFold provider selection in the model-picker path and savedProviderByName with exact trimmed persisted-name matching. Added s/ſ coverage.

Validation completed: focused regressions, go test ./..., go vet ./..., release build, release smoke, govulncheck, and git diff HEAD --check. make is unavailable on this Windows workstation; advisory static lint still reports only the unrelated pre-existing ST1005 finding at internal/peermsg/private_dir_windows.go:107. The race regression could not run because this environment has CGO disabled (-race requires cgo).

Consider making the provider-identity behavior more explicit in output and tests. When key deletion is skipped because another row shares the provider identity, explain that the key was retained for the other profile rather than reporting only that no key was removed. Also add the reverse "s" lookup assertion in the identity test to ensure distinct folded identities remain independently addressable.

Both CLI commit callers report the unsanitized input profile instead of ProviderCommitResult.Persisted. CommitProviderProfile returns the persisted row with APIKey cleared and APIKeyStored set.

I found issues that need to be addressed before this is ready.

Findings

  • [P1] Restore the ChatGPT service-tier contract
    internal/tui/commands.go:272
    On the base, /fast is a supported ChatGPT-subscription command and its priority selection flows through model.serviceTieragent.Options.ServiceTierzeroruntime.CompletionRequest → the chat-completions and Codex Responses request bodies. This head removes every link in that chain: it deletes the command/dispatch/state, removes the request fields, and stops serializing service_tier in both OpenAI transports. A subscriber who had fast mode enabled before updating now receives an unknown-command response and silently sends default-tier requests instead of service_tier: "priority"; there is no warning, migration, or release-note claim. This PR is supposed to establish provider identity primitives, not remove a ChatGPT capability. Rebase this branch so the existing end-to-end command and wire contract remains unchanged. If deprecation is intentional, make it a separate compatibility PR that documents the affected plans, explicitly clears/migrates saved state, and has release notes.

  • [P2] Do not silently discard supported high reasoning settings
    internal/providers/openai/provider.go:506
    On the base, openAIReasoningEffort forwards minimal, low, medium, high, xhigh, and max; this head accepts only the first four. The same unrelated cleanup removes ultra from modelregistry.ValidReasoningEffort and deletes the per-model live-catalog effort metadata that lets the picker validate choices. A session/profile already using xhigh or max does not get an error: it continues running with reasoning_effort omitted from the API request, silently changing output quality and cost/latency behavior; ultra becomes newly invalid. This capability removal is unrelated to identity validation. Rebase it out of this PR and preserve the existing wire values and metadata. Any future narrowing needs a separately reviewed compatibility policy covering persisted preferences, active sessions, picker validation, user-facing error text, and migration/release notes.

  • [P1] Preserve the ChatGPT live-model discovery protocol
    internal/tui/picker.go:409
    Before this change, modelPickerDiscoveryOptions obtains the OAuth resolver and the exact selected login key, then supplies both the resolver and CodexAccountResolverForLogin(loginKey) to DiscoverCatalog. The resolver makes a 401 refreshable, while the account resolver lets discoverOpenAIModels attach the matching chatgpt-account-id; both are required to query an account-scoped Codex model list correctly. This head instead copies a token into APIKey and passes providermodeldiscovery.Options{}, so the request cannot refresh and lacks the account resolver/header. Separately, it narrows parseModelsResponse from the Codex endpoint's models[].slug protocol (with visibility filtering) to data[].id only. Thus a ChatGPT /model request either fails authorization or cannot parse a successful Codex response, then falls back to the stale static catalog and hides current subscription-entitled models. The deleted picker/discovery tests covered these exact bearer, account-header, refresh, and models[].slug contracts. Rebase these changes out of #892 so the shared account-bound OAuth/discovery path and Codex protocol support remain intact; retain the focused protocol tests rather than deleting them.

  • [P1] Keep the provider transaction out of this identity-only slice
    internal/config/provider_commit.go:1
    The PR description explicitly assigns locking, config/key transactions, rollback, and OpenRouter persistence to #894, and #894's own description promises one transaction over add/setup, catalog ensure, OpenRouter, manager edit/rename/remove, marker cleanup, logout, migration, and the remaining credential writers. This head nevertheless introduces CommitProviderProfile and lockProviderWrite and wires them into only add/setup paths. It does not cover the full writer inventory: saveOpenRouterProviderKey still performs EnsureCatalogProvider → store SetMarkProviderAPIKeyStored outside the lock; manager key edits capture outside it; and logout/marker cleanup use separate unlocked read-modify-write helpers. An OpenRouter flow can therefore read an old config, a concurrent locked add can publish a new provider, and OpenRouter can subsequently write its stale EnsureCatalogProvider snapshot, dropping that provider. Conversely, a logout marker-clear can publish APIKeyStored:false after a concurrent commit stores a replacement secret, leaving that new credential unreachable. The partial lock also uses O_EXCL with no dead-holder recovery, so a crash after acquisition leaves all of its covered writes permanently "busy". Do not expand this transaction inside #892: remove the premature implementation and rebase this PR back to the identity boundary. #894 should introduce a single authoritative transaction for every config/key lifecycle mutation, using its declared fail-closed lock policy and interleaving, rollback, and process-interruption tests.

PierrunoYT added a commit to PierrunoYT/zero that referenced this pull request Aug 14, 2026
Review on Gitlawb#892 asked for the config/key transaction to stay in Gitlawb#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. Gitlawb#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.

I found issues that need to be addressed before this is ready.

The identity primitives in internal/config and internal/credstore are the right foundation. Preflight-before-capture on add/setup/wizard, case-variant marker cleanup on logout, and the resolver's exact-then-identity active selection are real progress. What keeps blocking merge is not “more polish on the same idea” — it is that this PR changed a cross-cutting contract and then stopped halfway through wiring it. The findings below are mostly the same failure mode at different call sites, not nine unrelated bugs.

Please read Why this keeps generating review rounds and How to close this in one pass before touching individual items. Fixing them one file at a time in response to the next comment will produce another round with the same shape.

CodeRabbit also asked for logout fail-closed on config-path resolution and a non-zero exit when provider removal cannot delete the stored key. Those behaviors are unchanged from merge-base dc15e82 and are not introduced by this PR; they are omitted here so this review stays scoped to split-owned defects.


Why this keeps generating review rounds

1. The PR scope and the actual diff disagree

The description says PR 1 is “deliberately limited to internal/config helpers, internal/credstore, and their direct tests — no CLI or TUI behavior changes.” The current head changes 21 files across CLI and TUI: auth, setup, provider onboarding, command center, provider manager, provider wizard, and model lookup. That is not wrong for a split — identity primitives are useless until boundaries consume them — but it means every consumer you touch in this PR must be made internally consistent with the new contract. Shipping new writer.go semantics while leaving adjacent CLI/TUI paths on the old mental model is exactly what produces drip review.

2. The split plan deferred infrastructure, not responsibility for breakage

The 4-PR stack correctly assigns catalog ownership (#893), full config/key transactions (#894), and selection UX (#895) to later slices. That does not mean PR 1 can introduce incompatible producer/consumer pairs and leave them for #894 to discover:

Deferred to later PR Still required in this PR for every path you already changed
#894 — lock + CommitProviderProfile over full writer inventory Validate before store mutation; restore-on-failure instead of blind delete; consistent marker/secret ordering
#893 — credential-candidate ownership resolver Correct survivor predicate: retain key only when a remaining row has APIKeyStored
#895 — list/use UX, ZERO_PROVIDER sync Bridge user/session spelling → exact persisted row before exact mutators; sync in-memory TUI state after disk writes

You already landed and then reverted CommitProviderProfile on 6c65153 per review feedback — correct scope decision. The revert also removed the narrow bridges that had been compensating for capture-before-validate and concurrent TOCTOU on add/setup. Reverting the transaction without replacing it with the small shared helpers below re-opened every boundary the transaction had been masking, which is why OpenRouter key loss and similar issues are back.

3. Reviews have been fixing symptoms, not completing the contract

Across ~6 author commits and 4 jatmn review rounds, the pattern is:

  1. Review identifies a boundary where identity rules disagree (e.g. logout deletes by normalized key, clears marker by exact spelling).
  2. Author patches that boundary (e.g. ClearProviderKeyStoredCaseVariants).
  3. The next review finds the same class at the next caller (wizard remove, OpenRouter save, providers remove work, model persist).
  4. Repeat.

That is not reviewer nitpicking. It is what happens when a repo-wide identity split is implemented as point fixes instead of one shared resolution layer + one credential lifecycle + one session sync policy.

Concrete example from this branch's history:

  • Round 3 (8e9823b) added ProviderCredentialSurvives, CommitProviderProfile, and OpenRouter restore-on-failure.
  • Round 4 (6c65153) correctly removed the partial transaction for #894 — but ProviderCredentialSurvives and the OpenRouter restore path went with it, and callers fell back to the narrower providerIdentitySurvives (name exists, not key owned). The author comment on 8e9823b describes fixes that are not on the current head.

Until the helpers below exist in internal/config and every changed CLI/TUI path uses them, each review pass will keep finding the next unplugged hole.

4. Two identity rules need one front door — you added the rules but not the door

This PR correctly defines:

  • Credential identitySameProviderIdentity / credstore.NormalizeProvider
  • Exact row identity — trimmed provider.Name equality for row-targeting mutators
  • Publication validationValidatePersistedProviderNames on write

The recurring defects all look like:

user/session input  →  [gate uses identity]  →  [mutator uses exact]  →  mismatch
                  or
preflight OK        →  store.Set            →  validate fails       →  destructive rollback
                  or
disk updated        →  in-memory session stale until restart

Merge-base used EqualFold everywhere, which hid the split. This PR made the split real in writer.go but not at every boundary that calls into it. Every finding in this review is one of those four patterns.

5. Tests prove local scenarios, not the invariants

The test additions are substantial and valuable, but they are organized as per-finding regressions (logout case variants, wizard failure injection, repair remove exact spelling). What is missing is enforcement of the invariants this PR claims:

  • No store.Set / SecureProviderProfile before PreflightUserConfig / ValidatePersistedProviderNames passes for the intended write.
  • No CLI/TUI path calls an exact mutator with user input that has not been resolved to a persisted row spelling.
  • No credential delete unless CredentialKeyRetained is false.
  • No successful TUI close after a disk mutation without reloading session provider state.

Without invariant tests, go test ./... staying green does not mean the contract is complete — it means the tested scenarios pass.

6. What will not stop the dripping (please avoid)

  • Another pass of “replace EqualFold at the line mentioned in the review” without auditing all provider-name comparisons by intent.
  • Re-introducing CommitProviderProfile only on add/setup while OpenRouter/logout/wizard stay outside it (#894 owns the full transaction; a second partial lock is worse).
  • Closing items by making confirm text or exit codes look better while the underlying store/config/session divergence remains.
  • Claiming remaining gaps are “#895 UX” when they are correctness bugs in paths this PR already changed (providers remove work, model persist spelling).

How to close this in one pass (recommended approach)

Treat the next commit series as finishing the boundary contract, not answering nine separate tickets.

Step A — Add four shared helpers in internal/config (small; not #894)

These are the minimum infrastructure the split requires. They belong in PR 1 because PR 1 already changed every caller.

ResolvePersistedProviderName(cfg, input) (exact string, error)

  • Collect all rows where sameProviderIdentity(row.Name, input).
  • 0 matches → not found.
  • 1 match → return that row's exact Name.
  • 2+ matches → same error shape as ValidatePersistedProviderNames (ambiguous repair state).
  • SetActiveProvider already contains this loop; extract it instead of copying a fourth time.

CredentialKeyRetained(cfg, removedName) bool

  • True only if some remaining row has sameProviderIdentity(row.Name, removedName) and row.APIKeyStored.
  • Replace duplicated providerIdentitySurvives in provider_onboarding.go and provider_manager.go.
  • When retaining a key but the sole survivor lacks a marker, migrate the marker to the survivor as part of removal (document and test this repair policy once).

PublishProviderCredential(path, exactName, key string) error (name flexible)

  • PreflightUserConfig(path) first.
  • Snapshot existing store value for exactName (if any).
  • store.SetMarkProviderAPIKeyStored(path, exactName).
  • On marker failure: restore snapshot, return error (non-zero at CLI boundary).
  • OpenRouter, setup key capture, and wizard finalize should all call this or an internal equivalent — not hand-rolled Set + Mark + Delete rollback.

ReloadProviderSessionFromDisk(m *model, cfg FileConfig) (or TUI-local wrapper)

  • After any wizard/manager mutation: refresh savedProviders, providerProfile, manageActiveName, providerName from returned FileConfig.
  • One helper prevents the next “disk says X, session says Y” finding.

Step B — One audit, not nine spot fixes

Run these searches across internal/cli, internal/tui, and internal/config and classify every hit:

Search Intent
EqualFold near provider/name Row selection → exact trim; credential question → SameProviderIdentity; neither → bug
ProviderPersisted followed by RemoveProvider / RenameProvider / SetProviderModel Must insert ResolvePersistedProviderName between them
store.Set / SecureProviderProfile / deleteProviderKey Must be preceded by preflight or followed by compensating restore
_, _ = config.Set Must surface or use resolved spelling from prior call's return value
Confirm/copy about key removal Must call CredentialKeyRetained on simulated post-delete cfg

Fix every hit in the same commit series. That is what stops drip.

Step C — One integration matrix test (table-driven)

Add a single table test (CLI + config writer + credstore temp dirs) covering:

Scenario Assert
Legacy openrouter/OPENROUTER + existing key + auth openrouter Config bytes unchanged; key restored
Sole row WORK, providers remove work Succeeds; key removed if applicable
Duplicate work/WORK, providers remove work Unambiguous error before persisted gate passes
{work: stored, WORK: not stored}, remove credentialed row Survivor can ApplyStoredAPIKey OR key deleted — per chosen policy
activeProvider: WoRk, repair remove one duplicate activeProvider is exact survivor spelling
Persisted OpenAI, session openai, model switch Model written to OpenAI row

This catches the class permanently; per-finding tests become rows in the table.

Step D — Be explicit in the PR description about what #894 still owns

After the pass above, update the description to say PR 1 does wire boundary compatibility (preflight, resolve, survivor predicate, session sync) and does not implement cross-process locking or the full writer-inventory transaction. That prevents the next round from re-litigating scope.


Root cause summary (maps findings → pattern)

Pattern Findings
Store/config mutate before validate or without restore P1 OpenRouter
Survivor predicate uses name not ownership P2 providerIdentitySurvives
Identity gate + exact mutator without resolve bridge P2 remove/rename, P2 model persist
Disk updated, session not P2 wizard key remove
Secret before marker, no compensation P2 wizard remove ordering
Repair mutator doesn't normalize derived pointers P2 activeProvider
User-visible copy not driven by same predicate as behavior P2 delete confirm
Leftover EqualFold at identity boundary P3 wizardProviderStoredKey

Findings

  • [P1] Preserve the working OpenRouter key when duplicate-name validation rejects publication
    internal/cli/auth.go:134 (saveOpenRouterProviderKey)

    What happens. saveOpenRouterProviderKey calls EnsureCatalogProvider (first EqualFold match, no validation), then store.Set overwrites the normalized credential, then MarkProviderAPIKeyStored runs ValidatePersistedProviderNames and rejects legacy openrouter/OPENROUTER duplicate rows. The rollback calls store.Delete, removing the working key entirely while config.json is unchanged. The CLI exits 0 and prints a manual-export hint.

    Reproduce. Config with both openrouter and OPENROUTER rows and an existing stored key. Run zero auth openrouter. Store entry is gone; config unchanged.

    Pattern. Capture-before-validate with destructive rollback. Fixed on add/setup via preflight; not applied here. Was fixed in 8e9823b and lost in 6c65153 revert.

    Fix. Route through PublishProviderCredential (see Step A). Non-zero exit on publication failure. Regression: legacy duplicate + existing key → config bytes and key both preserved.

  • [P2] Delete the stored key only when no remaining row still owns the credential
    internal/cli/provider_onboarding.go:479, internal/tui/provider_manager.go:414 (providerIdentitySurvives)

    What happens. Retains the credential whenever any same-identity row remains, even if the only survivor has apiKeyStored: false. Repairing {work: apiKeyStored:true, WORK: apiKeyStored:false} by removing work orphans the secret. CLI/TUI messaging implies success.

    Reproduce. Two case-variant rows; only one marked stored. Remove the credentialed row. Survivor cannot load the retained key.

    Pattern. Name survival used as credential ownership. ProviderCredentialSurvives from 8e9823b addressed this but is not on current head.

    Fix. CredentialKeyRetained in internal/config; delete duplicated predicates. Decide and test marker migration to survivor on repair remove.

  • [P2] Bridge case-variant remove/rename input to the exact persisted row
    internal/cli/provider_onboarding.go:408, runProvidersRename at :515

    What happens. ProviderPersisted uses identity; RemoveProvider/RenameProvider require exact spelling. zero providers remove work on sole row WORK passes persisted check then fails not found. Merge-base EqualFold masked this.

    Reproduce. Sole row WORK. zero providers remove work or rename work acme.

    Pattern. Identity gate + exact mutator without ResolvePersistedProviderName. providers use works because SetActiveProvider bridges; remove/rename do not.

    Fix. Resolve before mutating (Step A). Ambiguous multi-row → error before persisted gate. CLI tests for sole-row case variant and duplicate-row repair.

  • [P2] Sync in-memory provider state after wizard key removal
    internal/tui/provider_wizard.go:1351 (applyManageKeyChoice, Remove branch)

    What happens. Disk and store updated; savedProviders / providerProfile still show APIKeyStored: true until restart.

    Reproduce. Wizard manage-key Remove → /providers or re-enter wizard without restart.

    Pattern. Disk-first mutation without session reconciliation.

    Fix. ReloadProviderSessionFromDisk (Step A) or reload saved providers before closing wizard. Wizard test: in-memory state matches disk immediately.

  • [P2] Clear the persisted marker before deleting the shared secret in manage-key removal
    internal/tui/provider_wizard.go:1341 (applyManageKeyChoice, Remove branch)

    What happens. deleteProviderKey then clearProviderKeyStored. Marker failure after successful delete leaves apiKeyStored: true with no secret.

    Reproduce. Inject marker-clear failure after successful store delete.

    Pattern. Secret-before-marker ordering; logout was fixed, wizard was not.

    Fix. Marker first, secret second, or shared atomic helper with store rollback on marker failure.

  • [P2] Normalize activeProvider when repair removal leaves a stale spelling
    internal/config/writer.go:403 (RemoveProvider active handoff)

    What happens. activeProvider: "WoRk" with rows work/WORK can remain after deleting one duplicate, pointing at no row. Exact mutators fail until manual edit.

    Reproduce. Config above; RemoveProvider(path, "WORK"); activeProvider still WoRk.

    Pattern. Repair mutator fixes rows but not derived pointers that used a third spelling.

    Fix. After removal, if activeProvider matches no remaining exact name and one row remains, set it to that survivor's spelling. Writer test for WoRk scenario.

  • [P2] Match delete confirmation text to shared-key retention policy
    internal/tui/provider_manager.go:780 (renderManageStep), deleteManagerSelection at :366

    What happens. Confirm always promises key removal. Implementation retains key when a same-identity survivor exists. Post-delete notes already branch correctly; confirm does not.

    Reproduce. Case-duplicate rows sharing identity. Delete one from manager.

    Pattern. Copy not driven by same predicate as behavior (CredentialKeyRetained).

    Fix. Compute retention before confirm; share helper with post-delete notes.

  • [P2] Persist model changes with the resolved row spelling used for activation
    internal/tui/command_center.go:583 (switchProviderModel), same in persistSelectedModel

    What happens. SetActiveProvider (identity) succeeds; SetProviderModel (exact) fails silently with _, _ = when session spelling differs from persisted row.

    Reproduce. Row OpenAI; switch model using openai spelling. Session updates; config model does not.

    Pattern. Identity gate + exact mutator; resolved cfg.ActiveProvider ignored.

    Fix. SetProviderModel(path, cfg.ActiveProvider, model) after activation. Surface errors. TUI test for case-variant persist.

  • [P3] Match stored-key detection to credential identity in the wizard
    internal/tui/provider_wizard.go:1310 (wizardProviderStoredKey)

    What happens. Still uses EqualFold; conflates s and ſ despite distinct store keys.

    Reproduce. Distinct s/ſ rows with separate stored keys; wizard for s may attach to ſ flow.

    Pattern. Incomplete EqualFold audit (Step B).

    Fix. SameProviderIdentity for credential matching. Extend wizard tests beyond ASCII case.


Closing note

Nine findings read like a lot. They are one contract finish job: add the four helpers, run the audit once, land the matrix test, update the PR description to match what this slice actually owns. That is the difference between another review round in a week and closing PR 1 so #893#895 can build on a stable baseline.

Thanks — the "one contract finish job, not nine tickets" framing was the right call, and I took the recommended approach rather than patching each site. Pushed as 3fee2c83.

Step A — the four helpers

Helper Notes
config.ResolvePersistedProviderName(path, input) Exact spelling wins, credential identity is a fallback, 2+ identity matches is an error. SetActiveProvider's loop was extracted into it rather than copied a fourth time, as suggested.
config.CredentialKeyRetained(providers, removedName) Ownership, not name survival: retain only when a remaining row has APIKeyStored. Both duplicated providerIdentitySurvives copies are deleted.
config.PublishProviderCredential(path, exactName, key) Preflight → snapshot → store.SetMarkProviderAPIKeyStored; on marker failure it restores the snapshot (or deletes only an entry it created), never the blind store.Delete.
applyProviderKeyRemovalToSession(name) (TUI) Reconciles savedProviders / providerProfile after a disk key removal. Copies the slice before mutating, since model is passed by value with a shared header.

Plus ProviderKeyRetainedAfterRemoval(path, name) so confirmation copy and delete behavior are computed from the same predicate.

Policy decision on the markerless survivor (you left this "per chosen policy"): repairing {work: stored, WORK: not stored} by removing work deletes the key rather than migrating the marker to WORK. Resurrecting a credential onto a row the user never marked seemed worse than requiring a re-add, and it keeps one rule — "the marker is ownership" — instead of two. Documented on CredentialKeyRetained and covered in both directions in the matrix.

Step B — one audit

  • P1 OpenRouterPreflightUserConfig now runs before EnsureCatalogProvider's EqualFold lookup, then PublishProviderCredential owns capture+publish. Non-zero exit on publication failure; the minted key is still printed for manual use.
  • P2 survivor predicate — both call sites on CredentialKeyRetained.
  • P2 remove/rename bridge — resolved between the ProviderPersisted gate and the mutator; ambiguous duplicates error before anything is touched. Same bridge added to the TUI manager's delete and edit paths, whose row names come from the resolved list.
  • P2 wizard session sync and P2 marker-before-secret — both in applyManageKeyChoice.
  • P2 activeProvider normalizationRemoveProvider re-points a stranded WoRk at the survivor's spelling when exactly one row carries the identity.
  • P2 delete confirmation — driven by ProviderKeyRetainedAfterRemoval at arm time.
  • P2 model persistswitchProviderModel uses the spelling SetActiveProvider resolved; persistSelectedModel resolves first. Errors are surfaced in the status line instead of _, _ =, but only for a row that is persisted — env-derived providers stay silent, since there is nothing to write.
  • P3 wizardProviderStoredKey — on SameProviderIdentity.
  • EqualFold sweep — classified every provider-name hit in auth.go (ensureLoginProviderProfile and the OpenRouter active check), picker.go (savedProviderModelPickerItems), provider_wizard.go (appendOAuthLoginProfile), provider_wizard_discovery.go (active-row selection → exact), session.go (resume summary), and config.EnsureCatalogProvider.

Also removed PersistedProviderNames, which the ownership helpers made dead.

Two things I found while doing this

  1. auth logout used two different stores. ForgetProviderKey deletes from the default-path store while the marker cleanup targets configPath. They coincide in production but diverge for a non-default config, so logout could clear a marker while the secret stayed put. Both halves now use the store beside the config being edited, matching providers remove.
  2. An existing test asserted the old wizard ordering (TestProviderWizardManageKeyRemoveReportsCleanupFailures/stored key deletion required the marker to survive a failed secret delete). I inverted it: the new contract is that a failed delete leaves an orphaned secret nothing reads, never a marker claiming a key that is gone. The error message now says so explicitly.

Step C — the matrix

TestProviderIdentityMatrix in internal/cli (CLI + config writer + credstore temp dirs), eight rows:

Scenario Asserts
Sole row WORK, providers remove work Row removed, key deleted
Sole row WORK, providers rename work acme Row and activeProvider renamed
Duplicate work/WORK, providers remove Work Ambiguity error; config byte-for-byte unchanged; key untouched
{work: stored, WORK: stored}, remove work Key kept; survivor can ApplyStoredAPIKey
{work: stored, WORK: not stored}, remove work Key deleted, not orphaned
activeProvider: WoRk, remove one duplicate Exact survivor spelling; exact mutator can address it
Persisted OpenAI, providers use openai activeProvider is OpenAI
s + ſ with separate keys, remove s ſ row and its secret untouched

Per-finding regressions were kept for the OpenRouter rollback, logout marker cleanup, confirmation copy, session sync, wizardProviderStoredKey, and case-variant model persistence, plus config-level tests for each new helper.

Step D

PR description rewritten: it now states that PR 1 does wire boundary compatibility (preflight, resolve, ownership predicate, restore-on-failure, session sync) and does not implement cross-process locking or the full writer-inventory transaction, which stays with #894.

Validation

go build ./..., go vet ./..., gofmt -l . clean, go test ./... fully green.


On the two invariants I could not encode as tests: "no store.Set before preflight" and "no exact mutator called with unresolved input" are currently enforced by the audit plus the matrix rows, not by a check that would fail on a new unwired caller. If you want that enforced structurally, the natural shape is making SecureProviderProfile and the exact mutators unexported behind the helpers — but that is a larger surface change than this slice should carry, so I left it. Happy to open it as a follow-up if you'd rather have it than a convention.

@coderabbitai — worked through all six. Four fixed in 408f996a, two declined with reasoning below.

Fixed

Report rollback failure instead of discarding it (credentials.go) — taken as suggested. A failed rollback leaves the store holding a key the config does not describe, which is precisely the state the caller needs to hear about, so it is joined into the returned error rather than reported as a plain publication failure. The key value stays out of the message.

Resolve the provider name before calculating key retention (writer.go) — correct catch, and it was reachable: the TUI passes row.profile.Name from the resolved list, so a case-variant spelling removed nothing from remaining and the preview could say "key kept" for a delete that resolves the row and takes the key with it. ProviderKeyRetainedAfterRemoval now resolves through resolvePersistedProviderName first and returns its error.

That surfaced a second case worth handling: with resolution now failing for an env-derived row, a bool keepsKey would have defaulted the prompt to "This also removes its stored API key" for a delete that removes nothing. The confirmation carries a note string instead, and makes no claim at all when there is nothing to promise — no config path, no persisted row, or a config too ambiguous for the delete to proceed. Covered by TestProviderDeleteKeyNoteMakesNoClaimWithoutAResolvableRow and TestProviderDeleteKeyNoteResolvesCaseVariantSpelling.

Add persistence failure regression coverage (command_center_test.go) — added TestSwitchProviderModelReportsPersistenceFailures: unreadable config, a row the write cannot resolve, and the env-derived case that must stay silent (no row to update is not a failure, and a note there would be noise on a normal ambient-OPENAI_API_KEY switch).

Do not print credential values in test failure messages — applied to every assertion this branch added, in credentials_test.go, provider_identity_matrix_test.go, and auth_test.go: presence and length instead of the key, named fields instead of %+v on a ProviderProfile. I left the pre-existing occurrences elsewhere in provider_wizard_test.go / provider_manager_test.go alone as unrelated to this diff.

Declined

Use the user-scoped credential store for runtime credential operations — I do not think this one is reachable, and applying it would regress an existing intentional behavior.

ProviderKeyStore() is defined as ProviderKeyStoreAt(filepath.Dir(DefaultUserConfigPath())), and in these CLI paths configPath comes from deps.userConfigPath, wired to config.DefaultUserConfigPath in app.go. So filepath.Dir(configPath) is the user config dir — the two resolve to the same store in production, and diverge only when a test injects a path.

The configPath-relative form is also a deliberate prior decision rather than an accident: removeStoredProviderKeyAt carries a comment saying the key must be deleted from the store co-located with the config being edited "not the default-path store, so a non-default config path cannot leave the encrypted key behind", and TestRunProvidersRemoveDeletesKeyBesideConfig asserts exactly that. Switching to ProviderKeyStore() would break it.

This diff actually moves toward that convention rather than away: auth logout previously deleted through ForgetProviderKey (default-path store) while clearing the marker at configPath. That is a genuine divergence — for a non-default config, logout could clear the marker while the secret stayed put — so both halves now use the store beside the config, matching providers remove. TestRunAuthLogoutClearsMarkerForCaseVariantSpelling covers it.

Happy to be corrected if the learning refers to a runtime lookup path I have missed, but for these write paths the two stores are the same object and the co-located form is the tested contract.

Serialize credential publication and rollback — the analysis is right that credstore.Store has no interprocess lock and concurrent read-modify-write can lose updates. That work is explicitly assigned to #894, and the human review on this PR asked for the opposite of adding it here: a partial CommitProviderProfile/lockProviderWrite was landed on 8e9823b and removed on 6c65153 as out of scope, with the note that "a second partial lock is worse" than none. #894 introduces one authoritative transaction over the full writer inventory with its declared fail-closed lock policy, plus interleaving and process-interruption tests.

PublishProviderCredential is deliberately shaped to slot into that transaction rather than to hand-roll a competing one: it already funnels validate → snapshot → set → publish → restore through a single entry point, so #894 wraps it instead of rewriting each call site.

Validation

go build ./..., go vet ./..., gofmt -l . clean, go test ./... fully green.

@PierrunoYT Verified the changes in 408f996a.

  • PublishProviderCredential now reports a rollback failure with the publication failure. It does not include the credential value.
  • ProviderKeyRetainedAfterRemoval now resolves the persisted provider name before it calculates retention.
  • The TUI delete confirmation makes no credential claim when no persisted row can be resolved.
  • TestSwitchProviderModelReportsPersistenceFailures covers invalid config, ambiguous rows, and the silent environment-derived case.
  • The changed test assertions do not print stored credential values.

I withdraw the credential-store concern for these config mutation paths. SecureProviderProfile, PublishProviderCredential, and provider removal intentionally use the store beside the edited config. The runtime lookup contract remains separate: it uses config.ProviderKeyStore().

I also accept the serialization boundary. PR #894 owns the complete writer transaction and locking policy. A partial lock in this PR would create a competing transaction boundary.

Thanks for the detailed rationale and the focused regression coverage.

Learning: In Gitlawb/zero, distinguish runtime credential lookup from config-mutating credential operations. Runtime lookups use `config.ProviderKeyStore()` and the default user-config directory because provider API keys are user-scoped. Config-mutating operations, including `config.SecureProviderProfile`, `config.PublishProviderCredential`, and CLI provider removal through `removeStoredProviderKeyAt`, use `config.ProviderKeyStoreAt(filepath.Dir(configPath))` so the credential store is co-located with the config file being edited. `internal/cli/provider_onboarding_test.go:TestRunProvidersRemoveDeletesKeyBesideConfig` verifies this contract.

Learning: In this repository, provider API keys are user-scoped by design: runtime credential lookups intentionally use the user credential store regardless of where a `config.ProviderProfile` was resolved from, and `internal/config/credentials.go:ProviderKeyStoreAt(dir string)` exists primarily for test isolation rather than to support repo-scoped/shared credential stores.

Review on Gitlawb#892 asked for the config/key transaction to stay in Gitlawb#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. Gitlawb#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.

Adds the shared helpers the identity split needs, then routes every CLI and
TUI provider path through them instead of patching each boundary separately.

internal/config:
- ResolvePersistedProviderName bridges credential-identity input to the exact
  persisted row spelling that row-targeting mutators require (exact wins,
  identity is a fallback, ambiguity is an error). SetActiveProvider now uses it.
- CredentialKeyRetained decides key retention by OWNERSHIP (a survivor with
  APIKeyStored), not by name survival, so a markerless case variant can no
  longer orphan a secret. ProviderKeyRetainedAfterRemoval answers the same
  question before mutating, for confirmation copy.
- PublishProviderCredential owns validate -> capture -> publish and restores
  the previous stored key when publication is rejected, replacing hand-rolled
  Set + Mark + Delete rollbacks.
- RemoveProvider re-points an activeProvider stranded on a third spelling.

Consumers:
- auth openrouter preflights before EnsureCatalogProvider and publishes through
  the transaction; a login that cannot be persisted now exits non-zero.
- auth logout clears the marker before deleting the secret, and both halves use
  the store beside the config being edited.
- providers remove/rename resolve user input to the exact row.
- TUI manager delete, manager edit, wizard key removal, and model persistence
  resolve spellings the same way; wizard key removal clears the marker first and
  reconciles the live session; the delete confirmation is driven by the same
  retention predicate as the delete.
- EqualFold audit: provider-name comparisons in auth, picker, wizard, wizard
  discovery, session summary, and EnsureCatalogProvider now use the credential
  store's rule or exact row spelling, by intent.

Tests: a table-driven CLI+config+credstore identity matrix, plus regressions
for OpenRouter key preservation, logout marker cleanup, retention policy,
confirmation copy, session sync, and case-variant model persistence.

- PublishProviderCredential joins a failed rollback into the returned error.
  A store left holding a key the config does not describe is the state the
  caller most needs to hear about, and it must never surface as a plain
  publication failure. The key value stays out of the message.
- ProviderKeyRetainedAfterRemoval resolves the provider name the same way the
  delete does. Previewing against an unresolved case variant removed nothing,
  so a "key is kept" preview could precede a delete that resolves the row and
  takes the key with it.
- The manager delete confirmation carries a note string rather than a bool, so
  a row with nothing to claim — env-derived, no config path, or a config too
  ambiguous for the delete to proceed — makes no promise about the stored key
  instead of asserting a removal that cannot happen.
- Redact credential values from the test failure messages added in this branch:
  report presence and length instead of the key, and named fields instead of a
  whole ProviderProfile.

Tests: persistence-failure coverage for switchProviderModel (unreadable config,
unresolvable row, and the env-derived case that must stay silent), and
confirmation-note coverage for the unresolvable and case-variant rows.

Addresses the review tail on Gitlawb#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 Gitlawb#894.

Addressed review 4996916725 on rebased head 2b8faf39.

  • Fresh base: rebuilt the branch on current upstream/main (ad34dc8d) and force-updated the PR branch. The sole rebase conflict was additive CHANGELOG.md content; the provider Unreleased entries remain above main's complete 0.8.0 release section.
  • Sandbox approval contract: internal/sandbox/command_prefix.go and internal/execution/contracts.go are byte-identical to current main. Versioned/build-suffixed interpreter launchers remain excluded from reusable prefix grants, their regressions remain present, and the current policy version is preserved.
  • Release baseline: .release-please-manifest.json, package.json, and package-lock.json are byte-identical to current main. The release build and smoke test both report 0.8.0.
  • Homebrew boundary: internal/update/installmethod.go is byte-identical to current main, retaining Cellar detection and managed-install refusal behavior.
  • Active-provider repair: RepairUnnamedProvider now treats a nonempty active name that matches no named row as the legacy selector for the sole unnamed row. An explicit providers repair-config --name work migrates that reference to work in the same atomic repair write. A matching named row still preserves the existing active reference. Config-level and real CLI regressions both perform a fresh config.Resolve after repair and assert the repaired row is immediately usable.

Validation on the pushed head:

  • focused config/CLI repair regressions
  • go fmt ./...
  • go vet ./...
  • go test ./... — 85 packages passed, 5 with no tests
  • go run ./cmd/zero-release build
  • go run ./cmd/zero-release smoke
  • pinned static lint — 0 issues
  • pinned govulncheck — no vulnerabilities
  • git diff HEAD --check
  • explicit no-diff checks against main for the sandbox policy, release tuple, and Homebrew files

I found issues that need to be addressed before this is ready.

Merge readiness

  • [P1] Clear the active changes-requested review after addressing the current head
    GitHub review state
    GitHub reports this PR as mergeable but blocked with CHANGES_REQUESTED. The base is current and every required check is green, so there is no rebase or CI blocker, but the branch still needs a fresh approval after the code findings below are fixed.

Overall guidance

These findings are not six unrelated edge cases. Most come from the same underlying problem: resolved providers from user config, project config, environment discovery, and the live session are flattened into ProviderProfile values and then identified again from the display Name. At that point the code no longer knows which source produced a row or whether a name is an exact persisted-row identifier, a credential identity, or only a live/session spelling. Helpers such as ProviderPersisted, ResolvePersistedProviderName, savedProviderByName, and normalized comparisons then try to reconstruct ownership from the string. That works for a sole case variant, but it becomes unsafe as soon as exact case-sibling profiles exist across layers—the configuration resolver explicitly permits that state.

Please address that ownership gap once rather than adding another comparison at each failing call site. A resolved/provider-manager/picker entry should retain enough provenance to answer at least: its exact profile identity, whether it is backed by the user config, and—if so—the exact persisted row name. User-config mutators should require that persisted-row reference; project/env rows should remain session-only unless an explicit operation publishes them into user config. For lookups where only a name is available, use one shared rule: exact match first, normalized fallback only when exactly one candidate exists, and an ambiguity result rather than first-match selection. The active-provider check, picker lookup, provider switch, model persistence, manager edit, manager delete, key-retention decision, and live-state reconciliation should all consume the same resolved identity instead of independently interpreting Name.

The regression suite should exercise this as a matrix, not one helper at a time. Include user work plus project WORK, both active-provider orders, different endpoints/models, one user-backed row plus an env-only sibling, a sole case variant, and s/ſ as distinct credential identities. For delete, edit, model selection, and provider switching, assert all four outcomes: the exact runtime profile passed to newProvider, the exact user-config bytes/row changed (or unchanged), the credential-store key retained/deleted, and the in-memory savedProviders/active session state. Those end-to-end assertions will catch a fix that corrects the visible row but still writes or deletes through the wrong backing identity.

The remaining findings reflect three smaller contract gaps: preflight must happen before irreversible remote work and again before publication; model-only reconciliation must be a partial update rather than a full edit with zero values; and the valid CLI command set should have one authoritative definition—or at least a parity test—so dispatch, help, and generated completions cannot drift apart. Fixing those boundaries and the provider provenance model should close the class of problems represented by this review rather than only the individual reproductions below.

Findings

  • [P1] Do not map an exact project row onto a case-folded user row
    internal/tui/provider_manager.go:358
    The resolved manager may validly contain user work and project WORK, because cross-layer provider merging is exact. Selecting exact WORK makes ProviderPersisted(userConfigPath, "WORK") succeed on user work; ResolvePersistedProviderName then finds no exact WORK in the user file and falls back to work. Delete removes that user row and may delete its normalized credential, while edit applies the project row's draft—including a replacement key—to work. The subsequent in-memory operation targets exact WORK, so it removes or updates a different row than the one changed on disk.

    The root cause is that a manager row carries a resolved profile but no backing-source or persisted-row identity, and the mutation path treats “shares a credential identity with a user row” as “is that user row.” Carry user/project/env provenance and the exact persisted name into providerManagerRow; only call user-config/key mutators for rows explicitly marked user-backed. A project/env row should be removed from the session or reported non-editable, not bridged onto a folded user row. Add delete and edit regressions with user work plus project WORK that assert the user config and credential store remain byte-for-byte unchanged when WORK is selected, while the intended session row is the only in-memory row affected.

  • [P1] Preserve exact provider ownership in model-picker routing
    internal/tui/model.go:4418
    With active user Target and project provider target, an item rendered under exact target compares equal to the active provider through credential normalization, so this branch sends its model to handleModelCommand and rebuilds/persists Target. If a switch path is reached, savedProviderByName("target") returns the first normalized match instead of preferring the exact project profile. savedProviderModelPickerItems also marks both siblings active by credential identity. A selection displayed under one endpoint can therefore rebuild another endpoint and persist the model on the wrong user profile without any visible warning.

    This has the same provenance root cause as the manager defect, plus a first-match lookup. Give picker items a stable resolved owner reference rather than only OwnerProvider string, or resolve that string through one exact-first/unique-normalized helper that returns ambiguity instead of the first match. Compare the resolved owner row—not credential normalization—to the resolved active row, pass that exact profile to newProvider, and persist only when that owner is actually backed by a user row. Cover both active orders for Target/target, give the profiles different base URLs and models, and capture the profile passed to newProvider; the test should also prove that selecting the project row does not update the case-sibling user row in config.json.

  • [P2] Preflight OpenRouter before starting remote authorization
    internal/cli/auth.go:111
    This calls the browser login and receives a newly minted key before the first PreflightUserConfig, which only runs later in saveOpenRouterProviderKey. For a legacy unnamed or duplicate-name config, a failure already knowable from local state is delayed until after the browser flow creates a live remote credential. The command then exits non-zero and hands the orphaned key to the user, despite the new OAuth documentation promising validation before authorization and the sibling CLI/TUI flows doing that initial check.

    The root cause is that validation was placed only inside the publication helper, after the irreversible boundary. Use a two-check lifecycle: call preflightAuthLogin before openRouterLogin to reject known-invalid local state without opening the browser, and retain PreflightUserConfig immediately before EnsureCatalogProvider/publication to catch changes made while authorization was in progress. Add a regression where invalid config makes the injected openRouterLogin callback fail the test if invoked, alongside the existing race/publication tests that prove the second check and credential rollback still work.

  • [P2] Make bare repair avoid or explain a colliding default name
    internal/config/writer.go:145
    For {activeProvider:"Groq", providers:[{name:""},{name:"Groq"}]}, the documented bare providers repair-config assigns Groq to the unnamed row, rejects its own proposed duplicate, leaves the file unchanged, and reports that the file contains duplicate Groq rows. The actual file has one unnamed row; the duplicate exists only in the rejected candidate state, and the working --name <unique> escape is not mentioned. The same problem occurs when the implicit openai fallback is already owned.

    The root cause is that activeProvider is used both to determine whether it already selects a named row and as the unnamed row's default replacement. Once activeMatchesNamedRow is true, that value is evidence that the active pointer belongs to the other row—not a safe inferred name for the unnamed one. In that branch, either choose a deterministic unused name or stop before mutation with an error that says the proposed name collides and shows zero providers repair-config --name <unique-name>. Test both active-name and openai fallback collisions through the CLI, assert the failure leaves the file byte-for-byte unchanged, and assert the guidance command succeeds followed by a fresh Resolve.

  • [P2] Preserve descriptions during model-only saved-state sync
    internal/tui/provider_manager.go:796
    syncSavedProviderModel constructs a partial ProviderEdit with only Name and Model, but applySavedProviderEdit is a full-edit mirror and unconditionally assigns profile.Description from the edit's empty description. Every successful model persistence therefore clears a nonempty description from savedProviders, while config.json retains it. The manager, picker, and any model copies sharing the slice backing array then disagree with disk until a fresh resolution.

    The root cause is using a value struct with no field-presence semantics as both a complete edit and a partial patch. Keep syncSavedProviderModel surgical—copy the slice/profile as needed and update only Model—or introduce explicit optional fields/update masks so an omitted description differs from an intentional clear. Extend both model-persistence paths' tests with a profile containing description, base URL, catalog/provider metadata, and stored-key state; after the switch, assert only Model changed in memory and that unrelated model copies are not accidentally mutated through a shared slice.

  • [P3] Add repair-config to the shared completion command tree
    internal/cli/completions.go:45
    The PR dispatches and documents providers repair-config, but the authoritative providers completion node omits it. Consequently every generated Bash, Zsh, Fish, PowerShell, and Elvish script offers the old command set, so zero providers rep<Tab> cannot discover the recovery command named by the new validation errors.

    The immediate fix is to register the leaf and assert it in completionContexts. The root cause is that dispatch, help text, and completion metadata maintain separate command inventories with no parity check. Prefer deriving those surfaces from one command definition; if that is too large for this PR, add a focused test that enumerates the documented/dispatched provider subcommands and requires every one to appear in the providers completion context. That prevents the next provider command from repeating the same omission across all five generators.

Re-approving at 2b8faf39. My approval this morning was dismissed by the rebase plus one new commit, and the new commit is a bug I did not catch.

repair-config --name renamed the unnamed row but left activeProvider pointing at the old legacy selector, so the command reported success and Resolve then could not find the active provider. Driving it here on a config whose activeProvider is groq with a single unnamed row:

$ zero providers repair-config --name legacy-groq
Named legacy provider legacy-groq in ...\config.json     rc=0
   activeProvider = "legacy-groq"   rows = ["legacy-groq"]
$ zero providers list
  * legacy-groq [openai-compatible] ...                  rc=0

Migrating the reference inside the same atomic write is right. A repair that leaves the config unresolvable is not a repair, and doing it in a second write would have its own failure window.

Falsified by dropping the migration:

--- FAIL: .../explicit_name_migrates_legacy_active_reference
    active provider = "legacy", want repaired name
--- FAIL: TestRunProvidersRepairConfigMigratesLegacyActiveReference
    fresh Resolve after repair: no active provider configured: active provider "legacy" not found

The second one asserts through a fresh Resolve, which is the check that matters: it fails the way a user would experience it rather than on an internal field.

sameProviderIdentity as well as exact match in the row scan is the right call too, since the whole point of this PR is that those two spellings are one identity.

Nothing further from me. The bare repair-config note from my last review still stands as a non-blocking nit if you want it.

Six findings from the latest review round, most tracing to one root cause:
resolved providers from user config, project config, environment discovery,
and the live session are flattened into ProviderProfile values and then
re-identified from the display Name. A row's Name says nothing about which
layer produced it, so "shares a credential identity with a user row" was
being treated as "IS that user row" — unsafe as soon as exact case-sibling
profiles exist across layers, which the resolver explicitly permits.

## Provider identity ownership (P1 x2)

internal/config/provider_ownership.go adds the ownership model the review
asked for: LookupProviderName is the ONE shared rule for resolving a
spelling against candidates (exact first, unique-normalized fallback,
Ambiguous — not first-match — for several), and
ResolveProviderRowOwnership/ProviderRowOwnershipAt answer "which exact
persisted row, if any, does this resolved row own?" — rejecting a
credential-identity match when a DIFFERENT resolved row already carries
that persisted row's exact spelling (the case-sibling shadow).

providerManagerRow now carries owner config.ProviderRowOwnership, resolved
once per row against the whole displayed list when the manager reloads.
Delete, edit, and the delete-confirmation key note all consume row.owner
instead of re-deriving it from a name lookup — closing the defect where a
project WORK row edited or deleted through a user work row it merely
shared a credential identity with.

savedProviderByName, the model-picker owner-routing branch, the "is this
row active" badge, and persistSelectedModel/switchProviderModel's
persistence gate are rewritten onto the same rule: compare resolved ROWS,
not credential identities, and refuse to write when ownership is
ambiguous or shadowed rather than picking a row at random.

A necessary follow-up mid-implementation: switchProviderModel's silent
path for a genuinely environment-derived provider (no persisted row at
all) had to stay silent, matching prior behavior — only the surprising
outcomes (shadowed by a sibling, ambiguous) earn the new session-only
note. ProviderRowOwnership.Lookup/.Shadowed exist so callers can tell
these apart without parsing Reason's text.

## OpenRouter preflight (P2)

runAuthOpenRouter now calls preflightAuthLogin before the browser PKCE
flow, matching the sibling chatgpt/login commands, instead of only inside
saveOpenRouterProviderKey after the flow already minted a live remote
credential. The second check stays in place immediately before
publication — the config can change while the browser flow is open.

## Bare repair colliding with its own default name (P2)

RepairUnnamedProvider stops proposing activeProvider as the unnamed row's
name once activeProvider already selects a DIFFERENT named row (evidence
the pointer belongs to that row, not a name for this one), and now checks
the proposed default for a collision BEFORE mutating rather than building
a candidate, rejecting it, and reporting an "ambiguous" state the file
never had. The rejection names the owning row and the working --name
escape. The function also returns the name it actually chose, so the CLI
stops re-deriving it and reporting the wrong one.

## Model-only saved-state sync (P2)

syncSavedProviderModel no longer routes through applySavedProviderEdit,
a full-edit mirror with no field-presence semantics: it now copies the
slice and updates only Model, so a model persistence no longer clears a
nonempty Description (and other holders of the old backing array are not
affected by a copy that never mutated in place).

## Completion parity (P3)

providersSubcommands in command_center.go is the one inventory dispatch,
help, and the completion tree now share (via aliasNodes), plus a parity
test, so repair-config shipping in the first two while no generated
completion script offered it cannot happen again for the next command.

Tests: internal/config/provider_ownership_test.go pins the ownership
matrix (exact, shadowed sibling in both directions, sole case variant,
env-only, ambiguous, distinct s/long-s identities) and the shared lookup
rule directly. internal/tui/provider_ownership_test.go exercises delete,
edit, and model-picker selection end-to-end with a live user `work` +
project `WORK` pair in both active orders, asserting the config bytes,
credential store, and in-memory session state together — not just the
visible row. CLI and config packages get direct regressions for the
OpenRouter preflight ordering and both repair-config collision shapes.

Validation: go build ./..., go vet ./... (also on Linux via WSL,
go1.26.6), gofmt clean, deadcode clean, go test ./internal/{cli,config,
tui}/... green on both Windows and Linux. The internal/cli provider-config
test failures are pre-existing on this branch (confirmed identical
failure set against the unmodified branch) and unrelated to this change.

Addressed jatmn's 2026-08-22 review in 5ad69c0.

Provider identity ownership (P1 x2) — the shared root cause

Both P1s came from the same gap the review named directly: a resolved provider row's display Name says nothing about which layer (user config / project config / environment / live session) produced it, so code re-identified rows from that string and treated "shares a credential identity with a user row" as "IS that user row." With user work and project WORK both validly resolved side by side, that let a manager delete/edit or a picker selection aimed at WORK land on work's config row and credential instead.

New internal/config/provider_ownership.go:

  • LookupProviderName — the one shared rule for resolving a spelling against candidates: exact match wins, a credential-identity match is accepted only when exactly one candidate carries it, and several candidates return Ambiguous rather than the first one found (the first-match bug in the old savedProviderByName/picker routing).
  • ResolveProviderRowOwnership / ProviderRowOwnershipAt — answers "which exact persisted row, if any, does this resolved row own?" A credential-identity match is rejected when a different resolved row already carries that persisted row's exact spelling — the case-sibling shadow.

providerManagerRow now carries owner config.ProviderRowOwnership, resolved once per row against the whole displayed list on reload. Delete, edit, and the delete-confirmation key note all consume row.owner instead of re-deriving it. savedProviderByName, the picker's owner-routing branch, the "is this row active" badge, and persistSelectedModel/switchProviderModel's persistence gate are rewritten onto the same rule — compare resolved rows, not identities, and refuse to write under ambiguity/shadowing instead of guessing.

One thing I want to flag rather than bury: while wiring switchProviderModel I broke the existing silent behavior for a genuinely environment-derived provider (no persisted row at all) — it started emitting a session-only note where it used to say nothing. Fixed by adding ProviderRowOwnership.Lookup/.Shadowed so the caller can tell "not persisted at all" (stay quiet, matches prior behavior) from "shadowed by a listed sibling" or "ambiguous" (worth the note) without parsing Reason text. Caught by the existing TestSwitchProviderModelReportsPersistenceFailures/RecordsRecentHistory tests, not something I added — worth knowing this class of regression is easy to reintroduce at this call site.

OpenRouter preflight (P2)

runAuthOpenRouter now calls preflightAuthLogin before the browser PKCE flow, matching the sibling chatgpt/login commands, instead of only inside saveOpenRouterProviderKey after the flow already minted a live remote credential. The second check stays immediately before publication — config can change while the browser flow is open — and TestRunAuthOpenRouterPreservesExistingKeyWhenConfigRejected now seeds a valid config so the mid-authorization edit happens inside the OAuth callback, actually exercising that second check rather than getting caught by the first.

Bare repair colliding with its own default name (P2)

RepairUnnamedProvider no longer proposes activeProvider as the unnamed row's default once activeProvider already selects a different named row — that's evidence the pointer belongs to that row, not a free name for this one. The collision against the proposed default is now checked before mutation, so the error names the row that owns it and shows the --name escape, instead of building a candidate, rejecting it, and reporting an "ambiguous" state the file never actually had. The function also now returns the name it chose, so the CLI stops re-deriving it (and reporting the wrong one — it used to say "Named legacy provider Groq" about a row it had actually named "openai").

Model-only saved-state sync (P2)

syncSavedProviderModel no longer routes through applySavedProviderEdit — a full-edit mirror with no field-presence semantics that unconditionally assigned the edit's empty Description. It now copies the slice and updates only Model.

Completion parity (P3)

providersSubcommands in command_center.go is the one inventory dispatch, help text, and the completion tree now build from (via aliasNodes), plus TestProvidersSubcommandInventoryMatchesDispatchAndHelp holding all three to it, so repair-config shipping in dispatch+help while no generated completion script offered it can't happen again for the next provider command.

Tests

  • internal/config/provider_ownership_test.go — the ownership matrix the review asked for: exact row, shadowed sibling in both directions, sole case variant, env-only row, ambiguous persisted rows, and s/ſ as distinct identities — plus the shared lookup rule directly.
  • internal/tui/provider_ownership_test.go — delete, edit, and model-picker selection end-to-end with a live user work + project WORK pair in both active orders, asserting config bytes, credential store, and in-memory session state together (not just the visible row).
  • CLI/config regressions for the OpenRouter preflight ordering and both repair-config collision shapes (active-name-owned, openai-fallback-owned).

Validation

go build ./..., go vet ./... (also on native Linux via WSL, go1.26.6), gofmt clean, deadcode clean, go test ./internal/{cli,config,tui}/... green on both Windows and Linux. The internal/cli provider-config failures (active provider "chatgpt" not found) are pre-existing on this branch — confirmed identical failure set against the unmodified branch — and unrelated.

Not addressed: the merge-readiness rebase item and the earlier findings (interpreter-launcher normalization, release manifest rollback, Homebrew detection) from the prior review round — those are outside this round's diff and worth a separate pass.
