fix(all): count only in-window Claude usage in unified session reports - #2052
Supersedes #2020, which was opened from @igorovh's fork without maintainer edits enabled. This branch keeps @igorovh's commits unchanged and adds one merge of main on top, resolving a conflict with #2022 in rust/adapters/opencode/src/README.md.
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.
Merge with main
The only conflict was one paragraph in the OpenCode adapter README. It keeps this PR's description of in-window session counting plus #2022's closing sentence about ccusage opencode. The Rust changes from #2022 (focused OpenCode reports) merged cleanly; they touch a different path. Tests for ccusage-adapter-all, ccusage-adapter-claude, ccusage-adapter-opencode, and ccusage pass on the merged tree.
Makes unified session reports count only Claude usage inside the --since/--until window, matching ccusage claude session. Previously a session that continued past --until disappeared with its in-window usage, and one started before --since brought earlier usage along, so focused reports no longer added up to the unified one.
Filters Claude entries by date before session rows are built, as the daily reports already do.
OpenCode claude-agent rows still match by whole session, but only sessions with in-window usage count and rows outside the window stay.
A deduped copy's session counts on the day of its kept entry, matching the daily loader.
Updates the session reports doc and the OpenCode adapter README.
Written for commit b635c35. Summary will update on new commits.
Summary by CodeRabbit
Bug Fixes
Unified session reports now apply the selected date range to Claude usage, including sessions that continue beyond the end date.
OpenCode rows are excluded only when matching Claude usage for the same session falls within the selected date range; activity outside that range remains included.
Repeated turns from resumed or forked transcripts are counted once, on the date of the retained copy.
Documentation
Updated report guides to clarify date filtering and session-matching behavior.
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#2016
Claude session reports now filter usage to the configured date window. OpenCode deduplication uses counted Claude session-days and applies the same date window. Tests and documentation cover the updated reporting behavior.
Changes: Claude session date-window accounting
Layer / File(s)
Summary
Track Claude session-days for matching rust/adapters/claude/src/lib.rs, rust/crates/ccusage-adapter-all/src/loader.rs, rust/adapters/opencode/src/README.md, docs/guide/opencode/index.md
Claude deduplication records survivor indices and copied session IDs. Counted main-thread usage is represented by session and date, with copies using the survivor’s date. OpenCode matching checks the row date against Claude’s date window. Documentation describes these matching rules.
Filter Claude session totals to the report window 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
Claude session reports filter entries to the inclusive date window before summarizing. Tests verify that in-window usage is included and out-of-window usage is excluded, including when a session continues past --until.
ccusage/ccusage#2020: Changes date-window filtering for unified session totals and Claude-Agent deduplication.
ccusage/ccusage#2021: Changes Claude-Agent exclusion rules in focused OpenCode reports.
ccusage/ccusage#2007: Adds unified Claude/OpenCode deduplication based on Claude main-thread usage and session matching.

Explanation
[#2016] Objective: unified ccusage session must count the same in-window Claude usage as ccusage claude session. Filter Claude entries by date before session rows are built.
Evidence:
rust/adapters/claude/src/lib.rs (diff read at reviewed head): main_thread_sessions is replaced by main_thread_session_days. The new method returns distinct (session ID, date) pairs for non-sidechain entries that the caller's predicate accepts. A merged copy takes its survivor's day. The new unit test attributes_a_cross_session_copy_to_the_survivor_day checks this, including exclusion when the predicate rejects the survivor's date.
rust/crates/ccusage-adapter-all/src/loader.rs: the change summary states that Claude session rows use only entries in the inclusive date window. The counted-session set comes from in-window session days. Limitation: the loader.rs diff could not be read. The file read at head was truncated before the changed hunks. This step rests on the summary.
rust/crates/ccusage/tests/claude_cli.rs: per summary, a new test checks that unified and Claude session reports both total 1.0 for the same inclusive window and exclude later usage. The pre---since expectation changes from 3.0 to 1.0.
rust/crates/ccusage-adapter-all/src/tests.rs: per summary, a session active past --until keeps its in-window usage in both daily and session unified reports.
OpenCode claude-agent rows keep whole-session matching (#2007). An in-window check is added, as the issue allows. This does not break the objective.
Test results were not executed in this review.

Explanation
No unrelated change found. Mapping of changes to the #2016 objective:
rust/adapters/claude/src/lib.rs: session-day logic for in-window Claude entries and the survivor-day rule for merged copies. The copies index type change and the removal of main_thread_sessions support the same logic. Its only caller is the adapter-all loader.
rust/crates/ccusage-adapter-all/src/loader.rs (per summary): applies the date window to Claude session rows and to OpenCode claude-agent deduplication.
Tests in rust/crates/ccusage/tests/claude_cli.rs and rust/crates/ccusage-adapter-all/src/tests.rs cover this behavior.
Docs: docs/guide/session-reports.md, docs/guide/opencode/index.md, and rust/adapters/opencode/src/README.md describe the same behavior.
The OpenCode README sentence about ccusage opencode matching comes from the merge of main (#2022). It documents adjacent behavior. No #2022 Rust file appears in the reviewed change summary.
Limitation: the loader.rs diff was not read directly. Its scope rests on the change summary.

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.

ℹ️ No blocking issues found — the unified session window fix looks correct.
This matches the focused claude session behavior and keeps the OpenCode claude-agent dedup consistent with it.
Reviewed changes
Reviewed the full diff for unifying Claude session date filtering (7 files).
Claude entry filtering before session build: unified session reports now keep only in-window Claude entries, so sessions active past --until still show their in-window usage instead of vanishing.
Survivor-day dedup for copies: copies now keys off the survivor entry index, so a resumed or forked copy counts on its survivor's day, mirroring the daily loader.
OpenCode row skipping narrowed: claude-agent rows are skipped only when the session has in-window Claude usage and the row date itself is in the Claude window.
Docs and tests: session-report and OpenCode docs updated; new tests cover sessions running past --until and the renamed subagent-window test now asserts in-window-only cost.
This compares the Rust PR release binary against the configured base package on the same CI runner.

The regression test only checked the 100-token total. The old logic also
reached 100: it dropped the Claude session whose last activity fell after
--until and kept the OpenCode claude-agent copy of the same turn instead.
The test now asserts each row's source and session, so it fails on the old
behavior (an OpenCode `ses-agent` row) and passes only when the Claude
session `claude-native-a` keeps the turn.
Refs #2016
The unified tests used the same date for a turn and its copy in another
session, so they could not tell whether a copy's session is dated by the
survivor or skipped when the survivor is not counted. A direct test of
DedupedEntries::main_thread_session_days now repeats a turn a day earlier
in another session and asserts that the copy's session lands on the
survivor's day and drops out when is_counted rejects the survivor.

Large real-world-shaped fixture performance
Generated fixtures shaped from aggregate local log statistics: thousands of JSONL files, many small sessions, and a long tail of larger sessions. No real prompts, paths, or outputs are stored in the fixtures.
Fixtures: Claude /home/runner/_work/_temp/ccusage-large-fixture (1.01 GiB, 2597 files), Codex /home/runner/_work/_temp/ccusage-large-codex-fixture (1.01 GiB, 2597 files)
Base runs the published ccusage package from pkg.pr.new, installed before measurement; PR runs the published native ccusage binary from pkg.pr.new, installed before measurement. Both run --offline --json, measured by hyperfine with 0 warmups and 1 runs.
Peak RSS is measured separately with /usr/bin/time using 1 runs. Lower RSS ratios are better.

Lower medians and smaller artifacts are better. CI runner noise still applies; use same-run ratios as directional PR feedback, not release guarantees.
This compares the PR package against the configured base package on the same CI runner.
Package runtime diagnostics
Compares the PR package wrapper, the installed native optional dependency binary, and the workspace release binary on the same large fixture. This identifies whether slow package results come from JavaScript wrapper overhead, the published native binary build, or the Rust core itself.
Fixtures: Claude /home/runner/_work/_temp/ccusage-large-fixture (1.01 GiB, 2597 files), Codex /home/runner/_work/_temp/ccusage-large-codex-fixture (1.01 GiB, 2597 files)
All rows run --offline --json, measured by hyperfine with 0 warmups and 1 runs. This isolates wrapper overhead from the installed native optional dependency and the workspace release binary built on the runner.

Upstream tip: 660e07c (2026-11-13,
chore(pricing): update models.dev snapshot)
Previous fork base: 30b653f (the upstream commit this fork was synced to)
Synced 100 upstream commits on top of 30b653f: 53 automated pricing

86707db build(perf): make the PR performance comparison catch real regressions (ccusage#2061)
686a1a8 ci: support a merge queue on main (ccusage#2062)
Fork wins kept: the Codex optimized scanner with its fork-replay instant,
the Antigravity model resolver, the OpenCode retained-ledger cache with its
per-namespace rows, the SQLite on-disk cache, the table renderer, the fork
CI and tag-only release workflow, and the exact `=` dependency pins.
Hand-resolved conflicts:
rust/adapters/claude/src/lib.rs: the fork's DedupedEntries copy pairs stay
and take upstream's carries_more_usage_detail tiebreak (speed rank, then
a cache TTL split); main_thread_session_days reads the recorded session
of each copy.
rust/adapters/opencode/{loader,parser}.rs: the fork's retain_via_ledger
stays beside upstream's v2 compaction scan; SessionMessageKind and
MessageRowColumns carry the row type through the five-value scan.
rust/adapters/codex/{replay,parser}.rs: open_rollout_reader_with_capacity
and CodexForkReplay both land in the shared parser state.
rust/crates/ccusage-core/src/{cache,pricing}.rs: the opencode-db-compaction
namespace joins the ledger namespaces; the fork's embedded pricing loader
and OnceLock path stay.
rust/crates/ccusage/src/cli/timezone.rs: Cline joins the shared-args arm,
the ClearCache arm stays unreachable from the parser.
rust/Cargo.toml: the fork's exact `=` pins stay; jiff 0.2.41,
schemars 1.2.2, serde 1.0.229, smallvec 1.16.5, toml 1.2.1.
.github/workflows/{ci,release}.yaml: the fork's design is kept, including
its own release flow. Upstream's merge-queue, tagpr and pkg.pr.new jobs
need scripts this fork deleted, so they are not taken; the two
save-nix-cache inputs upstream passes to the native-package actions are
dropped because the fork's composite actions declare no such input.
packages/ccusage-*/package.json (6 files), the contribution-gate scripts,
sponsors.md, blacksmith.png and rust/adapters/claude/src/daily.rs stay
deleted; the two Blacksmith SVG logos upstream added are not taken.
Docs: the agent lists take upstream's Cline addition but keep this fork's
`pi` name, because the CLI subcommand is still `pi`; upstream renamed the
docs to `pi-agent` without renaming the command.
Snapshots regenerated for the fork table renderer: the Cline adapter, CLI
and unified reports, codex issue_2046, opencode compaction, claude session
--id and the config schema (new Cline section).
Validation: cargo test --workspace --offline 1297 passed, 0 failed; cargo
clippy --workspace --all-targets clean; rustfmt --check clean.
Version: take upstream's 20.0.50 in package.json, apps/ccusage/package.json
and docs/package.json; the Rust workspace keeps version 0.0.0.
DO NOT push a v20.0.50 tag from this fork: release.yaml would publish fork
bytes under upstream identity.

Supersedes #2020, which was opened from @igorovh's fork without maintainer edits enabled. This branch keeps @igorovh's commits unchanged and adds one merge of

Sessions that continued past--untilvanished with their in-window usage, and sessions started before--sincebrought earlier usage along — soccusage sessiondisagreed withccusage claude sessionand focused reports no longer added up to the unified one.This filters Claude entries by date before sessions are built (same as

The only conflict was one paragraph in the OpenCode adapter README. It keeps this PR's description of in-window session counting plus #2022's closing sentence about
ccusage opencode. The Rust changes from #2022 (focused OpenCode reports) merged cleanly; they touch a different path. Tests forccusage-adapter-all,ccusage-adapter-claude,ccusage-adapter-opencode, andccusagepass on the merged tree.Fixes #2016
