fix(claude): label alias tier slots in /model; count Anthropic cache tokens as input

[lidge-jun]

Summary

Two independent Claude-surface fixes, bundled.

Claude Code /model showed the OpenCodex alias on tier rows (Refs #6926). Claude Code 2.1.296 labels a tier row (Opus, Sonnet, Fable, Haiku) as ANTHROPIC_DEFAULT_<TIER>_MODEL_NAME, then its own name for a first-party id, then the raw value (read from the shipped binary). OpenCodex set ANTHROPIC_DEFAULT_OPUS_MODEL=ocx-claude-native--gpt-6.1-sol without the label, so the row printed the alias. Gateway rows were already fine because they carry display_name.

• New claudeTierDisplayName / claudeTierDisplayNameEnv in src/claude/context-windows.ts derive the label from the alias in the spelling discovery uses for display_name. ocx-claude-native--gpt-6.1-sol becomes gpt-6.1-sol (native), ocx-claude-cursor--gpt-5.6-luna[1m] becomes gpt-5.6-luna (cursor) · 1M, and the Fable picker alias becomes claude-fable-5-1 (anthropic) · 1M. A trailing --fast stays in the model name, because without the catalog a Fast sibling looks the same as a real --fast model. Non-alias values get no label.
• Labels pair only with slots OpenCodex wrote. ocx claude labels a slot only when setDefault wrote it. launchd system-env labels only tracked slots, and its produced-key sweep unsets a label the config no longer produces. The shell hook exports the label inside the branch that exports the slot, with shellValue quoting. A user-set slot or _NAME always wins, and a native launch drops the generated label together with the proxy-only slot it strips.
• The alias stays the submitted model id, so saved selections and inbound resolution are unchanged, as requested on the issue.
• Uses Refs rather than Closes: this is the confirmed tier-row defect, and closing the issue needs a /model check on the reporter's tier slot.

Anthropic-shaped coding-agent usage dropped cache tokens from input (carried from #6566). usageFromAnthropicShape reported Anthropic's cache-exclusive input_tokens as inputTokens. OpenCodex's contract is inclusive, and normalizeCostTokens returns null when cache read plus cache write exceeds input. A Claude CLI, CodeBuddy or Qoder turn with 12 fresh, 150,000 cache-read and 4,000 cache-write tokens therefore lost its cost estimate. Input is now fresh + cache read + cache write. The partial fold takes the maximum fresh input before adding the folded cache counters once, so repeated cumulative snapshots do not double count. Only this fix is carried. #6566's usage-admission and stable-replay parts stay in that PR, and #6566 stays open. Supersedes #6566 (partial carry: inclusive usage only).

#6532 needs no code change. Its fixes (#6552 0455845834, #6559 26dd8cf657, #6562 33125e62d2) are already on dev, and the issue stays open for live multi-account acceptance.

Docs: docs-site/.../guides/claude-code.md env table, structure/clients/claude-desktop.md (tier labels), structure/providers-and-adapters.md (inclusive usage), and the closed unit devlog/_fin/261011_claude_tier_labels_and_inclusive_usage/.

Verification

• Static checks on the pushed head: bun run typecheck, bun run structure:check and bun run privacy:scan all exit 0.
• Tests were not run locally. This lane's instructions route all test evidence to hosted CI on the exact head. New and updated tests:
  • tests/claude-integration/claude-context-windows.test.ts: labels equal the discovery display_name for base and 1M rows (native, routed, escaped, Fable alias). A real foo--fast model keeps its name. Non-aliases and legacy spellings are covered.
  • tests/claude-integration/claude-cli.test.ts: the launch env pairs the label. A user slot or user label wins. A native launch drops our label and keeps the user's.
  • tests/server/system-env.test.ts: launchd setenv and tracking, the paired shell branch with apostrophe quoting, a user-owned slot left unlabelled, and the sweep that unsets a withdrawn label.
  • tests/providers/codebuddy-protocol.test.ts: the reported 12 / 150,000 / 4,000 shape gives inputTokens 154,012 and a non-null normalizeCostTokens. A repeated-snapshot fold counts cache tokens once. Existing expectations moved to the inclusive totals, and codebuddy-tool-bridge-turn.test.ts was updated to match.
• Independent reviews by a fresh reviewer. Plan audit: FAIL, addressed, then PASS. Final diff: FAIL with one P2 (--fast labels), fixed, then PASS.

Checklist

• Scope stays focused and avoids unrelated cleanup.
• Docs or release notes were updated when needed.
• Security-sensitive changes were reviewed for secrets, auth, and unsafe defaults. No credential or auth path is touched. Labels are non-secret strings derived from configured model ids, and they go through the existing user-wins and tracked-lever paths with shell quoting.

Summary by CodeRabbit

• New Features
  • Claude Code now displays descriptive names for routed models in supported tier slots, while keeping the selected model IDs unchanged. Existing selections and custom labels are preserved, and environment variables let you override generated names.
• Bug Fixes
  • Anthropic usage totals now include cache-read and cache-creation tokens. Partial usage updates count fresh input and cache tokens without double-counting repeated snapshots.
• Documentation
  • Updated setup guidance with model-label overrides and clarified how cached tokens are counted.

📝 Walkthrough

Walkthrough

The PR adds derived labels for Claude tier aliases across CLI, launchd, and shell environments while preserving user-provided values. It also changes Anthropic-shaped usage conversion and partial-usage folding to include cache-read and cache-creation tokens in input totals.

Changes

Claude tier labels

Layer / File(s)	Summary
Derive labels for tier aliases src/claude/context-windows.ts, tests/claude-integration/claude-context-windows.test.ts, devlog/_fin/261011_claude_tier_labels_and_inclusive_usage/*	Adds helpers for the four Claude tier slots. The helpers derive labels from recognized aliases, include provider information, and preserve [1m] and --fast in the model label.
Add labels to Claude environments src/cli/claude.ts, src/server/system-env.ts, src/server/system-env-shell.ts, tests/claude-integration/claude-cli.test.ts, tests/server/system-env.test.ts, docs-site/src/content/docs/*/guides/claude-code.md, structure/clients/claude-desktop.md	CLI, launchd, and shell environment writers add labels for tier slots written by OpenCodex. Existing user values take precedence. Native fallback removes a matching label when it strips a proxy-only slot. Tests and documentation cover these paths.

Anthropic-shaped usage

Layer / File(s)	Summary
Include cache counters in input usage src/adapters/coding-agent/protocol.ts, tests/providers/codebuddy-protocol.test.ts, devlog/_fin/261011_claude_tier_labels_and_inclusive_usage/*	usageFromAnthropicShape clamps invalid and negative counters to zero, then includes cache-read and cache-creation tokens in inputTokens. Tests cover result usage and cost normalization.
Fold partial usage snapshots src/adapters/coding-agent/protocol.ts, tests/providers/codebuddy-protocol.test.ts, tests/providers/codebuddy-tool-bridge-turn.test.ts, structure/providers-and-adapters.md	Partial usage folding takes the maximum fresh-input count, then adds the maximum cache counters. Tests and documentation reflect the inclusive totals.

309-320: Label logic matches discovery format, with one edge case to confirm.

claudeTierDisplayName trims the selector and strips the [1m] marker. It then resolves the alias and builds the label. The tests compare the output with discovery display_name for native, routed, escaped and Fable aliases.

The --fast handling is intentionally conservative. The behavior is consistent with the tests at lines 295-302 of the test file.

689-694: Native fallback can leave a stale label when the slot has [1m] or whitespace edge cases.

The code deletes <slot>_NAME only when env[labelName] === label. claudeTierDisplayName(value) trims whitespace and handles [1m]. isProxyOnlyModelId strips only a lowercase [1m]. A slot value ending in [1M] would not match isProxyOnlyModelId, so the slot stays. This is consistent and safe.

The behavior is correct. The strict equality check preserves user labels.

118-123: LGTM!

320-327: Label ownership is evaluated against injectedKeys, which can include a slot tracked from a previous run.

injectedKeys.includes(slot) is true when an earlier run tracked the slot, even if the slot was not written this run. injectLever then refreshes the label. If the user changed the slot after tracking, injectLever for the slot skips the write only when the key is untracked. For a tracked slot it always overwrites. So the label stays consistent with the slot value the code writes.

Names at Line 33-34 are added to MANAGED_SYSTEM_ENV_NAMES, so readTracking keeps them. The produced-key sweep at Lines 346-358 unsets labels that are no longer produced. The tests at lines 827-848 of tests/server/system-env.test.ts cover this path.

⚠️ Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.

Fix the stale claude-* native label in the A-phase notes.

Lines 84-85 say a native claude-* slug gets the label "<slug> (anthropic)". This matches the code at src/claude/context-windows.ts Line 318. But the earlier plan text at Line 16 still says a native claude-* slug maps to "<slug>". The doc contradicts itself. Update Line 16 so readers do not implement the old rule.

Also, Lines 29-30 and 20 still describe the superseded --fast behavior at Line 18 ( · Fast). Lines 95-98 revise it. Mark the earlier lines as superseded.

Verify the /model rendering behavior before documenting it.

The generated ANTHROPIC_DEFAULT_{OPUS,SONNET,FABLE,HAIKU}_MODEL_NAME variables are documented as changing Claude Code’s /model labels. Environment-write tests do not establish that Claude Code renders these labels. Confirm the behavior in a fresh Claude Code process for each affected tier. If Claude Code does not render the generated label, qualify or remove this claim in all affected locale pages.

State when system environment integration writes the pair. The English source, docs-site/src/content/docs/guides/claude-code.md, limits launchd and shell-hook writes to when system environment integration is on. These translations omit that condition, which can imply the writes are unconditional.

• docs-site/src/content/docs/ja/guides/claude-code.md#L34-L34: Add the same system-environment condition.
