fix(all): count only in-window Claude usage in unified session reports by ryoppippi · Pull Request #2020 · ccusage/ccusage

ryoppippi · 2026-11-05T09:11:12Z

Opened on behalf of @igorovh (contribution gate blocked them from opening the PR).

Summary

Unified session with --until / --since was building each Claude session from every entry, then keeping it only when last activity fell inside the window. Sessions that continued past --until vanished with their in-window usage, and sessions started before --since brought earlier usage along — so ccusage session disagreed with ccusage claude session and focused reports no longer added up to the unified one.

This filters Claude entries by date before sessions are built (same as ccusage claude session and the other unified sources). OpenCode claude-agent rows still match by whole session per #2007, but only sessions with in-window usage count.

Test plan

CI green
On reporter data: Claude section of unified session matches ccusage claude session; unified session totals match daily
Midnight-crossing Claude Agent session still counted once (session-unit match)

Fixes #2016

Branch: main...igorovh:ccusage:fix/unified-session-date-window

Summary by cubic

Fixes unified session reports counting Claude usage outside the selected --since/--until window, so ccusage session now agrees with ccusage claude session and focused reports add up to the unified one. Sessions that continue past --until keep their in-window usage, and sessions started before --since no longer bring earlier usage along.

Filters Claude entries by date before building sessions, matching the other unified sources.
OpenCode claude-agent rows still match by whole session, but only sessions with in-window usage count, and the row's date must fall inside the Claude source's date range.
Updates docs to describe in-window session totals and the new counting behavior.

Fixes #2016.

Summary by CodeRabbit

Bug Fixes
- Session reports now include Claude usage recorded within the selected date range, even when a session continues beyond the end date.
- Matching OpenCode entries are excluded only when Claude usage for that session was counted within the date range and the entry’s date is also in range.
- When duplicate turns are merged, usage is credited to the day of the kept entry.

The unified session report built each Claude session from every entry and then kept it only when its last activity fell inside the window. A session that continued past `--until` vanished with its in-window usage, and a session started before `--since` brought its earlier usage along, so `ccusage session` disagreed with `ccusage claude session` and the focused reports no longer added up to the unified one. Claude entries are now filtered by date before sessions are built, like `ccusage claude session` and the other unified sources. OpenCode `claude-agent` rows still match by whole session, so a turn crossing midnight is counted once, but only sessions with in-window usage count and a row must fall inside the Claude source's date range. `DedupedEntries` keeps the survivor index of each merged copy, so a copy's session counts on the day of the kept entry, as in the daily loader. Fixes ccusage#2016

Walkthrough

Claude session reports now include usage within the configured date window even when a session continues beyond --until. OpenCode matching uses Claude’s date window for daily reports and remains session-wide for session reports.

Changes: Claude session date-window matching

Layer / File(s)	Summary
Derive counted session days `rust/adapters/claude/src/lib.rs`	`DedupedEntries` now returns counted session and survivor-date pairs. Copies retain their survivor index.
Apply date bounds to reports and matching `rust/crates/ccusage-adapter-all/src/loader.rs`, `rust/crates/ccusage-adapter-all/src/tests.rs`, `rust/crates/ccusage/tests/claude_cli.rs`, `docs/guide/session-reports.md`, `docs/guide/opencode/index.md`, `rust/adapters/opencode/src/README.md`	Claude session loading filters entries and session days to the configured date window. Daily-family OpenCode matching also checks the date window; session matching remains session-wide. Tests and documentation cover these rules.

Full details: Linked Issues check

Explanation

[#2016] Requirement: the unified session report must count the same in-window Claude usage as ccusage claude session. The diff in rust/crates/ccusage-adapter-all/src/loader.rs (load_claude_rows, Session kind) now filters deduped.entries with date_within_range before calling summarize_entry_sessions. The filter_session_summaries_by_last_activity step is removed for Claude rows. Counted sessions come from main_thread_session_days(in_window), so a session that continues past --until keeps its in-window usage. The claude_cli test changes the bounded unified-session expectation from 3.0 to 1.0 and adds a check that session and claude session both report the 1.0 in-window entry and exclude the 2.0 post-window entry. rust/crates/ccusage-adapter-all/src/tests.rs adds unified_session_counts_a_claude_agent_session_active_past_until. Code and tests establish the behavior for the reported case. Not verified: the reporter's dataset totals ($520.34 / 62 sessions) and CI. These are listed unchecked in the PR test plan and cannot be confirmed from the repository. The open question on OpenCode matching is not a requirement. The PR keeps whole-session matching for OpenCode, which the issue allows as an option.

Full details: Out of Scope Changes check

Explanation

All changed areas connect to #2016. rust/crates/ccusage-adapter-all/src/loader.rs: in-window filtering for Claude session rows, and the inclusive date check on OpenCode claude-agent rows in session reports. The PR description states this check is intended. rust/adapters/claude/src/lib.rs: main_thread_sessions is replaced by main_thread_session_days, which returns per-day session pairs. Copy records store the survivor index, and the sidechain post-pass moves into the new method. This supports the in-window session counting. Tests: the new and renamed claude_cli and tests.rs cases cover the fix. Docs (docs/guide/session-reports.md, docs/guide/opencode/index.md, rust/adapters/opencode/src/README.md): these describe the changed counting rule and are legitimate supporting changes. No unrelated behavior change was found in the reviewed hunks. The AI-generated summary of loader.rs says the date check applies to daily-family reports. The code applies it to the Sessions variant, which session reports use. The code and the PR description agree, so this does not affect the verdict.

Full details: Docstring Coverage

Explanation

Docstring coverage is 25.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 4 functions across 4 files. (3 skipped: 3 unsupported.)

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

✅ No new issues found.

Reviewed changes — unified session reports now count only in-window Claude usage, matching ccusage claude session and the other unified sources.

Filter Claude entries before building sessions — the session branch of load_claude_rows applies the date window to entries first instead of keeping whole sessions by last activity, so sessions spanning --until keep their in-window usage and pre-window usage is excluded.
Per-entry session-day dedup for OpenCode — main_thread_sessions becomes main_thread_session_days over survivor entries, so claude-agent rows match by session but only when the session has in-window Claude usage and the row date is in the Claude range.
Docs updated — session-report and OpenCode guides now describe in-window session totals and the session-unit dedup rule.
Tests added — past---until session counted once in daily and session totals, and pre-window subagent usage excluded.

Superseded by #2052, which keeps @igorovh's commits unchanged and merges main on top (this branch has maintainer edits disabled, so the conflict with #2022 couldn't be resolved here). Thanks for the fix!
