feat(hud): session reset timers and weekly/monthly cost tracking#190
Conversation
…etsAt to UsageData, CostAggregation type, and costHistory to GatherContext Co-Authored-By: Claude <noreply@anthropic.com>
Implements persistSessionCost (atomic write per session), aggregateCosts (merges active files + archive, deduplicates by max cost_usd), and getCostFilePaths (testable path resolution via DEVFLOW_DIR env var). Cleanup runs periodically: archives 24h-old sessions, trims archive at 90 days. Co-Authored-By: Claude <noreply@anthropic.com>
usage-quota: drop Session prefix, add formatCountdown helper for reset timers (↻2h15m format), show countdown after label and before bar. session-cost: extend to show weekly ($18.50/wk) and monthly ($62.30/mo) cost totals from costHistory when available. Co-Authored-By: Claude <noreply@anthropic.com>
render.ts: reorder Line 3 to model · configCounts · sessionDuration · sessionCost. index.ts: remove OAuth fetchUsageData, add extractUsageFromStdin (reads rate_limits from stdin directly), wire persistSessionCost and aggregateCosts for cost tracking. costHistory passed into GatherContext.

… extraction OAuth-based usage fetching removed; rate limits now read directly from stdin.rate_limits on each render. No network calls, no credentials needed. Co-Authored-By: Claude <noreply@anthropic.com>
hud-components.test.ts: add learningCounts/costHistory to makeCtx; update usageQuota tests to drop Session prefix, add resets_at fields, and test countdown rendering; add sessionCost tests for weekly/monthly. hud-render.test.ts: add costHistory to makeCtx; update usage assertions to drop Session prefix, add resets_at fields. cost-history.test.ts: new suite covering persistSessionCost (atomic writes, skip on zero cost, overwrite, concurrent sessions) and aggregateCosts (null handling, file reads, archive, dedup, window sums, malformed entry resilience). credentials.test.ts: deleted — credentials.ts removed.

Three discrepancies between the README preview and actual render: - Line 2 lacked 'Context' label prefix and used wrong quota format (↻ symbol with pre-bar countdown instead of parenthesized post-percent countdown) - Line 3 included ⏱ 15m (sessionDuration) which is removed from defaults - Feature description mentioned 'session duration' — removed Co-Authored-By: Claude <noreply@anthropic.com>
…-history - Extract nowEpoch() helper to deduplicate Math.floor(Date.now() / 1000) across 4 call sites - Add isSessionEntry() type guard replacing all unsafe JSON.parse casts - Fix !costUsd guard to costUsd <= 0 || !Number.isFinite(costUsd) to correctly reject NaN and negative values - Guard mkdirSync with sessionsDirCreated module flag to avoid redundant syscalls - Extract cleanOrphanedTmpFiles() and archiveStaleSessionFiles() from runCleanup to reduce nesting - Extract upsertMax(), readSessionEntries(), readArchiveEntries() from aggregateCosts to thin the orchestrator - Add 30s aggregation cache to avoid repeated filesystem reads on every HUD render tick Co-Authored-By: Claude <noreply@anthropic.com>
…sistence - formatCountdown JSDoc: remove stale "compact, no spaces" note (impl uses spaces) - renderQuotaWindow: add JSDoc showing rendered format - ComponentId JSDoc: replace "16 HUD components" count with accurate description - StdinData.rate_limits resets_at fields: annotate as Epoch seconds - sessionCost: add JSDoc documenting weekly/monthly totals - persistSessionCost call: guard with needsSessionCost so cost is only persisted when the sessionCost component is actually enabled Co-Authored-By: Claude <noreply@anthropic.com>
- Fix module isolation: add vi.resetModules() in beforeEach so module-level singletons (sessionsDirCreated, cachedAggregation) reset between tests; this fixes 15 pre-existing test failures - Fix misleading comment: "cache-busting" → accurate description of why dynamic import is used (DEVFLOW_DIR read at call time) - Add path traversal guard tests for persistSessionCost (/, \, empty string) - Add runCleanup test: verifies stale session files (>24h) are archived to archive.jsonl, triggered by mocking Date.now to a timestamp % 50 === 0 - Add formatCountdown describe block: past timestamp, 2h 30m, 2d 5h, 45m minutes-only, exact day (no hours sub-unit), exact hour (no minutes sub-unit) Co-Authored-By: Claude <noreply@anthropic.com>
