Pull request overview
SessionTimelineChart에서 타임라인 구간별 툴 호출 요약을 계산할 때, 기존의 중첩 반복(O(N*M))을 투포인터 기반 단일 순회(O(N+M))로 바꿔 렌더링 시 불필요한 순회를 줄이려는 PR입니다.
Changes:
- 툴 호출 요약 생성 로직을
filter기반 반복에서 투포인터 방식으로 변경해 시간 복잡도 개선 - 툴 요약 문자열 생성 로직을
formatToolSummary헬퍼로 분리 - (부수적으로) 파일 전반의 포맷팅(quote/semicolon/줄바꿈) 변경

- The two-pointer merge in chartData assumes toolCalls are sorted by parsedTimestamp; unlike the previous filter-based approach, unsorted TOOL messages would cause tool calls to be skipped/assigned to the wrong bar. Consider defensively sorting toolCalls (or at least sorting only when an out-of-order element is detected) so SessionTimelineChart stays correct even if callers provide unsorted messages.

packages/web/src/components/dashboard/session-timeline-chart.tsx:5
- This file was reformatted to double-quotes + semicolons, which is inconsistent with other dashboard chart components (e.g., packages/web/src/components/dashboard/token-usage-chart.tsx:1-5 and model-share-chart.tsx:1-6 use single quotes and omit semicolons). If the repo formatter/lint expects the existing style, this will create noisy diffs and possibly lint failures; consider reverting formatting-only changes and keeping the optimization minimal.

- These pnpm overrides use a ">=" range for Next.js (e.g. ">=15.5.21"), which has already resulted in a major upgrade to next@16.x in pnpm-lock.yaml. That’s a high-risk, unrelated change for a PR that claims to only optimize SessionTimelineChart; consider pinning to a concrete 15.x version (or splitting dependency upgrades into a separate PR).

- The new two-pointer bucketing logic is a core behavioral change (which tool calls get attributed to which timeline bar), but the existing SessionTimelineChart tests only assert that the chart renders. Adding a unit test that asserts toolSummary for multiple timeline points/tool calls would help prevent silent regressions.

- This file was reformatted to use double quotes + semicolons, while the surrounding web codebase commonly uses single quotes and omits semicolons (e.g. other components under packages/web/src/components). This makes the diff noisier than necessary and may conflict with repo formatting/lint expectations.

- Similarly, the
packages/webimporter now recordsnext-authwithspecifier: '>=5.0.0-beta.32'and resolves5.0.0-beta.32, while packages/web/package.json still declares"next-auth": "5.0.0-beta.30". This will breakpnpm install --frozen-lockfileand should be resolved by updating the manifest (if intended) and regenerating the lockfile, or by reverting the lock/override changes.
package.json:29 - This PR description focuses on a
SessionTimelineChartperformance optimization, but package.json introduces a large set of pnpmoverridesthat force upgrades across the dependency graph (e.g., next/next-auth/sharp/body-parser/js-yaml). That’s a significant scope change with upgrade risk and should either be called out explicitly in the PR description or split into a separate dependency-upgrade PR.

- The new two-pointer merging logic changes how tool calls are bucketed into timeline intervals. The existing test (session-timeline-chart.test.tsx) only asserts that the chart renders, but doesn’t validate
toolSummarybehavior across multiple timeline points or boundary cases (exactly-at-prev/exactly-at-current timestamps). Adding targeted tests would help prevent subtle regressions in this optimization.

- In pnpm-lock.yaml, the importer specifiers for packages/web have been rewritten to
next: specifier: '>=15.5.21'andnext-auth: specifier: '>=5.0.0-beta.32', but packages/web/package.json still declaresnext: "15"andnext-auth: "5.0.0-beta.30". This mismatch typically causespnpm install --frozen-lockfileto fail (and it also effectively upgrades Next/NextAuth far beyond what the manifest declares). Please either update packages/web/package.json to the intended versions/ranges or regenerate/revert the lockfile so the importer specifiers match the manifest.
package.json:29 - The PR description is scoped to a rendering-performance optimization in SessionTimelineChart, but this change adds a large set of root-level pnpm overrides (e.g., for next/next-auth/sharp/postcss/etc.). This is a substantial dependency-policy change and materially increases review and rollout risk relative to the stated purpose. Consider splitting dependency overrides into a separate PR (or explicitly updating the PR description with rationale, intended versions, and compatibility expectations).

- The new O(N+M) two-pointer bucketing logic for tool calls is a behavioral change (especially around boundary conditions at
prevTimestamp/currentTimestamp). Existing tests for SessionTimelineChart only assert that the component renders, and don’t validate tool-call assignment ortoolSummaryformatting. Please add test cases with multiple timeline points and tool calls around the boundaries (<= current, > prev) to ensure the optimized implementation matches the previous behavior.

- The override targets here use open-ended ranges (e.g., ">=...") which can make dependency resolution non-deterministic and allow unexpected major upgrades. In this PR, Next ends up resolving to v16 in pnpm-lock.yaml even though
@argos/webdeclares Next "15". Consider pinning override targets to exact versions (or at least constraining them to the intended major) to keep installs predictable and avoid accidental breaking upgrades.

- pnpm-lock.yaml now records
@argos/webwith Next specifier ">=15.5.21" resolving to 16.2.11, and next-auth specifier ">=5.0.0-beta.32". This conflicts with packages/web/package.json where Next is pinned to "15" and next-auth to "5.0.0-beta.30", so installs effectively upgrade versions via overrides. Please align the declared dependency versions (and/or overrides) with what you intend to ship, then regenerate the lockfile so it matches package.json.
packages/web/src/components/dashboard/session-timeline-chart.tsx:140 - The O(N+M) two-pointer merge is a correctness-sensitive change, but the current test suite for this component doesn’t assert the resulting toolSummary bucketing across multiple timeline points (boundary cases like tool calls exactly at prev/current timestamps, multiple tools, etc.). Adding a regression test (e.g., mock a Recharts chart component to capture the
dataprop and assert toolSummary per bar) would help ensure the optimization doesn’t change behavior.

- The tool-call bucketing logic was substantially changed (two-pointer traversal over
usageTimeline/toolCalls), but existing tests only assert the empty-state and that the chart renders. Please add unit tests that validatetoolSummaryoutput across multiple buckets (e.g., multiple tool calls, boundary timestamps atprevTimestamp/currentTimestamp, and multiple tool names) to prevent regressions in the new aggregation behavior.

pnpm-lock.yaml의packages/webimporter가next/next-authspecifier를 각각>=15.5.21,>=5.0.0-beta.32로 기록하고 실제로 Next 16.x / next-auth beta.32를 해석하고 있는데,packages/web/package.json은 여전히next: "15",next-auth: "5.0.0-beta.30"을 선언하고 있어pnpm install --frozen-lockfile(CI)에서 lockfile 불일치로 실패할 가능성이 큽니다. package.json과 lockfile/overrides 중 하나를 기준으로 버전을 정렬하고 lockfile을 재생성해 주세요.

pnpm.overrides가next@>=13.0.0 <15.5.21: ">=15.5.21"처럼 ‘범위 → 더 넓은 범위(>= …)’로 오버라이드되어, 선언된 major 범위를 넘어 Next 16.x로까지 올라갈 수 있습니다(현재 lockfile도 Next 16.2.11로 해석됨). 이 PR 설명은 차트 렌더링 최적화인데, major 프레임워크 업그레이드를 유발하는 overrides 추가는 범위가 크게 달라 리뷰/릴리즈 리스크가 큽니다. 보안 패치 목적이라면 (1) Next 15.x 내에서의 명시적 패치 버전으로 고정하거나, (2) Next 16 업그레이드를 별도 PR로 분리해 주세요.

eslint-config-next를^15.0.0으로 변경하면서, lockfile에서는next가 16.x로 해석되고 있습니다.eslint-config-next는 일반적으로 Next major와 맞추는 편이라(규칙/플러그인/권장 설정), 현재 상태는 린트 규칙 불일치나 예상치 못한 린트 오류를 유발할 수 있습니다.next/next-auth/eslint-config-next의 major 및 specifier를 일관되게 맞춘 뒤 lockfile을 재생성하는 것이 안전합니다.

- Two-pointer aggregation assumes
toolCallsis sorted by timestamp, butmessagesordering is a prop-level contract and isn’t enforced here. Ifmessagesever arrives out of order,toolSummarywill be wrong becausetoolIndexonly moves forward. Consider sorting the derivedtoolCallsonce (inside theuseMemo) so the algorithm is correct regardless of upstream ordering.
const toolCalls: ToolCallPoint[] = useMemo(() => {
return messages
.filter((m) => m.role === "TOOL")
.map((m) => ({
timestamp: m.timestamp,
toolName: m.toolName ?? "unknown",
parsedTimestamp: new Date(m.timestamp).getTime(),
}));

- The new O(N+M) tool-call bucketing logic is performance-critical and easy to get wrong around boundaries (tool call exactly at bucket timestamp, multiple buckets, tool calls after last usage, etc.), but the existing tests only assert that the chart renders. Please add assertions that
toolSummaryis computed correctly for multiple timeline points and tool calls across boundary timestamps.
const chartData: ChartDataItem[] = useMemo(() => {
// ⚡ Bolt: O(N*M) 루프를 O(N+M) 투포인터로 최적화 (N = 타임라인, M = 툴 호출).
// usageTimeline과 toolCalls 모두 시간순으로 정렬되어 있음을 활용하여,
// 한 번의 순회로 각 타임라인 구간에 속하는 툴 호출을 할당함.
const usageTimestamps = usageTimeline.map((u) =>
new Date(u.timestamp).getTime(),
);
let toolIndex = 0;
return usageTimeline.map((u, idx) => {
const currentTimestamp = usageTimestamps[idx]!;
const prevTimestamp = idx > 0 ? usageTimestamps[idx - 1]! : 0;
const relevantTools: ToolCallPoint[] = [];
while (
toolIndex < toolCalls.length &&
toolCalls[toolIndex]!.parsedTimestamp <= currentTimestamp
) {
if (toolCalls[toolIndex]!.parsedTimestamp > prevTimestamp) {
relevantTools.push(toolCalls[toolIndex]!);
}

- The new
pnpm.overridesentries use open-ended ranges like">=15.5.21"fornextand">=5.0.0-beta.32"fornext-auth. In practice this can jump to new majors (the lock now resolvesnextto 16.2.11) and makes the override intent unclear/risky for a rendering-performance PR. Prefer pinning overrides to an exact version (or at least an upper-bounded range) to avoid accidental major upgrades.

pnpm-lock.yamlnow shows the@argos/webimporter withnextspecifier'>=15.5.21'(resolved to 16.2.11) andnext-authspecifier'>=5.0.0-beta.32', butpackages/web/package.jsonstill declaresnext: "15"/next-auth: "5.0.0-beta.30". This suggests the lockfile was generated under different constraints (or edited indirectly via overrides) and may break frozen installs. Please regenerate the lockfile after aligning intended manifest + override versions.

💡 What:
SessionTimelineChart에서 타임라인 구간별 도구 호출 이력을 병합할 때, O(N*M) 시간 복잡도를 가지던 내부 루프(filter)를 O(N+M) 투포인터 방식으로 최적화했습니다.🎯 Why: 차트를 렌더링할 때마다 불필요한 날짜 객체 생성 및 배열 순회가 반복 발생하여, 데이터가 많을 경우 렌더링 지연(병목)의 원인이 될 수 있기 때문입니다.
📊 Impact: 도구 호출과 타임라인이 길어지는 세션에서 불필요한 배열 순회와 객체 할당을 줄여 차트 리렌더링 및 초기 로딩 성능이 향상됩니다.
🔬 Measurement: 개발자 도구의 Performance 탭에서 렌더링 소요 시간(ms) 단축을 확인할 수 있습니다.
