os.homedir() reads USERPROFILE on Windows and never HOME, so the
isolation setup and every test that moved home were still resolving the
developer's real home directory. Fixtures came back empty, real sessions
leaked into counts, and the code under test wrote plans, receipts and a
sync ledger into the real ~/.config/codeburn during a run.
USERPROFILE now joins the redirected variables and a shared setHome()
helper moves HOME and USERPROFILE together; every spawn env carries both.
The remaining Windows-only failures were POSIX-shaped fixtures: chmod
tricks that only toggle a read-only attribute on NTFS, pid 1 as an
always-alive lock holder, splitting paths on '/', bare tar, mode-bit
expectations, and per-file timeouts too short for the cost of a tsx spawn.
Each gets a platform-aware equivalent so nothing is skipped on Windows and
the POSIX branches stay byte-for-byte what they were.
Full run on Windows: 267 files passed, 2 skipped, 3592 tests passed.
Only Copilot CLI session-store rows carry total_nano_aiu, so a typical user
has a handful of exactly rated requests and hundreds of unrated ones, and
codeburn plan showed the exact-only sum as if it were the whole bill.
Price every unrated request from its tokens at listed API rates (1 credit =
$0.01) and carry that as estimatedCredits alongside creditRatedCalls /
creditUnratedCalls. A session that already carries an exact figure is never
estimated on top of: total_nano_aiu bills that request's whole token set,
JSONL twin included. spentCredits, the bar and percentUsed stay on GitHub's
exact figures. The plan headline, and status JSON via creditsNote, now say
how much of the total is estimated.
Spent credits are finite nanoAiu / 1e9. Token-priced costUSD does not
fill the Copilot bar. Thread nanoAiu through cachedCallToApiCall with
no cache-version bump.
Adds `codeburn plan set <id>` to configure a subscription plan (Claude Pro,
Claude Max, Cursor Pro, or custom). When set, the Overview panel renders
an API-equivalent progress bar against subscription price with a
projected month-end cost.
Closes the loudest demand signal on the repo: issue #11 ("Subscription
vs API Use") from two independent voices, plus the routing-decision use
case raised in #12.
- src/config.ts: extends CodeburnConfig with Plan, adds readPlan/savePlan/clearPlan
- src/plans.ts: presets (claude-pro $20, claude-max $200, cursor-pro $20)
- src/plan-usage.ts: getPlanUsage, resetDay-aware period math (1-28),
median-of-7-day-trailing projection
- src/cli.ts: `codeburn plan [show|set|reset]` subcommand, plan wired
into JSON outputs for report/today/month/status (only when active)
- src/dashboard.tsx: Plan row in Overview, color-coded (green under 80%,
orange near, red over), with days-until-reset
- README.md: Plans section with honest framing (API-equivalent vs
subscription price, not token allowance)
- tests/plan-usage.test.ts, tests/plans.test.ts, tests/cli-plan.test.ts:
period math, presets, CLI round-trip
Resets respect resetDay across month boundaries. Uses median daily spend
(not mean) so one huge day doesn't distort the month-end projection.
Fixes#11
