Linux parity review at CodexBar 0.60.4

Checked 2026-09-16 against Plasma commit 8d49266. The macOS reference is official v0.60.4, commit 937b20813cf47340093b6c312331c63a52768097, published 2026-09-16 at 12:22:58 UTC.

This is a release-delta review for useful Linux behavior. It covers published stable releases after the 0.58.0 review through 0.60.4, with targeted source inspection and scoped CLI probes. It does not repeat the full 0.56.2 contract audit. Current open parity work belongs in TODO.md.

Release coverage

Linux CLI contract changes since 0.58.0

Compared 88fa2f4...937b208 under Sources/CodexBarCLI/ (18 files) and the consumed Core payload models. JSON keys below are source-observed on shared Codable structs; fetcher-side behavior is CLI-owned. Nothing here replaces authenticated output evidence.

• Credit availability flags. CreditsSnapshot gains creditsAvailable: Bool? and balanceIsWorkspace: Bool (always encoded); balanceReadSucceeded is now false whenever the provider omits the balance, including cap-only responses. OpenAIDashboardSnapshot gains accountID, creditsAvailable, and balanceIsWorkspace, plus a computed requiresWorkspaceBalanceScope. The dashboard builder now hides credits unless balanceReadSucceeded. Plasma still reads remaining without these flags, so the TODO verification candidate grows but stays unverified for Linux output.
• Structured detail rows. ProviderDetailSection.Row gains optional id, progress: {used, total}, and usageValue, all Codable. Copilot seat-credit rows use stable IDs (copilot-seat-credits) and Antigravity local SQLite rows carry progress. Labels stay opaque display strings. Plasma (UsageDetails.js) keeps only label/value/secondaryValue, so the numbers are currently dropped. This is a new generic contract awaiting Linux output verification, not an implemented feature.
• Usage snapshot additions. copilotMeteredZeroCredits (encoded only when true) distinguishes a metered seat with no visible credit row from an unread balance. deepseekPlatformBalanceOwner is live-only. detailRow(id:) supports lookup by the new stable row IDs.
• Account identity. usage.identity gains no new fields; the token-account label helper now preserves accountID instead of dropping it. The Claude account-email gap is unchanged.
• Cost JSON unchanged. CostPayload, daily entries, and coverage keys are identical; OpenCodex pricing refresh and the partial-estimate marker affect values and text rendering within the existing schema.
• Status indicator unchanged. The enum moved to Core and label became cliLabel; raw values and English strings are identical.
• Cursor cost still gated. The cost provider set remains descriptor-driven (cli.supportsCostCommand); Cursor still lacks it, so cost --provider cursor is rejected before the dashboard-API path. The new cookie-source availability errors are unreachable on Linux until the gate changes.
• No config contracts. config gains no descriptors, generic set, or action commands; the diff is a secret-cleaning refactor. New CLI output formats (--format toon) and flags (--source, --all-accounts, --account-index, cost --provider-native-only/--group-by) add no JSON envelope changes. The removed CLIErrorReporting.printError had no callers.
• serve only. usageBarsShowUsed (bars default to remaining quota) flows through the dashboard snapshot and web UI operation key. Plasma does not consume serve.

0.59.0–0.60.4 features against existing Plasma behavior

• Cursor cost tracking (0.59.0–0.60.4). Still rejected on Linux (see probes). Plasma's cost path is fully generic per selected provider, so no frontend change is needed once the CLI emits data. The TODO blocker stands with a new verified version.
• Workspace balances and allowances (0.60.0). Codex owner-visible balances, DeepSeek daily spend, and Copilot seat entitlements arrive through the generic credits/openaiDashboard/details fields above. Displaying a typed balance without parsing provider text still needs the verified availability contract, so the balance-text and rich-usage blockers stand with new source evidence.
• Credit-pool percentages and quota counts (0.60.2). Warp/Perplexity/Abacus percentages, LongCat balances, LiteLLM budgets, and Manus/MiMo/Neuralwatt counts are CLI text/cards rendering over existing quota fields. No new Plasma contract; the rich-usage blocker already covers generic allowances.
• Last-known retention (0.60.4). Codex, Claude OAuth, Cursor, and DeepSeek keep prior measurements through transient failures with original timestamps. Plasma already retains last-known quotas with age limits and stale marking; the new usesLastKnownUsage marker is cards-text-only. Existing native behavior, no gap.
• Pace windows (0.59.0, 0.60.3–0.60.4). Optional macOS pace colors and the Cursor/Grok-Bot window fixes are menu presentation and fetcher corrections. Plasma pace indicators keep signed values and existing presentation; a color preference was evaluated and not added (macOS chrome, low value).
• Kimi exhausted monthly (0.59.0). Automatic-menu selection semantics owned by each frontend; the existing exhausted-selection verification candidate already covers useful differences.
• Antigravity recovery and dedup (0.60.0–0.60.2). Local-history recovery, structured-report fallback, and duplicate-row suppression are fetcher-side; Linux output flows through the generic path with no Plasma change.
• Devin on Linux (0.59.0). Manual Bearer settings with manual quota requests are CLI-owned; browser import stays macOS-only. The isolated probe without manual configuration still reports macOS-only web support, so the manual path is source-observed and unverified. No Plasma change (generic path).
• z.ai unavailable limits (0.60.1). Missing limits stay unavailable instead of rendering 100%; Plasma must already treat absent bounds as unknown. No new contract.
• Perplexity automatic window (0.60.x). Upstream simplified its automatic selection to the first display window; automatic selection stays frontend-owned on Plasma. No port.
• Account identity fixes (0.60.1). Fresh subscription dates, no cross-account inheritance on empty cards, token-account ID preservation, and Claude alias labels are reconciler-side. Linux identity fields are unchanged; the account-identity verification candidate stands.
• Linux desktop app and Omarchy widget (0.60.0). Separate Linux surfaces outside this Plasma widget. Excluded as non-goal; no behavior ported.
• Plugin switcher tabs (0.59.0). macOS menu chrome. Excluded.
• Documentation (0.60.2). The upstream Linux distro-dependency and install flow note (#3615) concerns the CLI/desktop archives, not this widget's requirements. No README change.

Scoped official Linux probes

The official CodexBarCLI-v0.60.4-linux-x86_64.tar.gz asset passed the release's SHA-256 check: 12b51e3016500a7068b73f45c50a034d0e436d6599430c83c1ee3112592005e3. Assets and checksum are on the official release.

Probes ran inside a network-isolated Bubblewrap process with temporary home, configuration, cache, and data roots, a cleared environment, and no host credentials reachable. No installed CLI was replaced. Executed from the extracted asset it reports CodexBar 0.60.4, which the probes used.

No authenticated usage, credit validity, workspace balances, Copilot seat rows, Antigravity progress rows, DeepSeek balances, z.ai limits, account switching, provider balance units, or nonempty cost history was exercised. Those limitations remain explicit in TODO; this is not a replacement for the full 0.56.2 audit.

Carried-forward blockers

Every blocker in TODO remains open. No 0.60.4 change adds a provider settings descriptor, generic config action, Cursor cost support, service-tier fields, cost availability metadata beyond historyCoverageIsEstablished, structured localization identifiers, or a display-currency contract. The new credit-availability and detail-row fields are source-observed only; the scoped 0.60.4 probes re-verify the descriptor rejection, the absent generic config commands, the Cursor cost rejection, and the unchanged cost/usage envelope shapes at this version. The 0.56.2 audit remains the contract baseline for unprobed authenticated cases.
