Release 0.83.0 — free-tier reasoning cap (W3) + scheduler contract (R6)

Public port of private #326 (28398970), merged 2026-07-31. Version files are
byte-identical to private/master. 3 files: pyproject.toml, graqle/__version__.py,
CHANGELOG.md. No code changes — the code already landed in #245.

⚠️ Contains a BREAKING CHANGE for the free tier

Reasoning on the free tier is now capped per calendar month; over the cap, calls that
previously succeeded raise ReasoningQuotaExceeded. Paid tiers are unaffected. The
CHANGELOG leads with the notice, names the exception and its import path, and gives the
upgrade path — this is the first release where a previously-working call can fail, so it
is called out at the top rather than buried in a feature list.

What ships

W3 reasoning-quota wall (ADR-245 Decision 8)	free monthly cap; gate at the SDK primitive so CLI, MCP, chat and server API are all covered; areason_stream and graq debate carry their own gates (they never reach areason)
CR-010.R6 scheduler contract	--headless / --json, normative exit codes, content-hash incremental rebuild

Verified from the built wheel — not source

Built graqle-0.83.0-py3-none-any.whl, installed it into a clean venv, and exercised
the wall end-to-end:

1) free user at cap, enforcement default ON   → BLOCKED  (quota reached: 30/30)
2) old bypass: GRAQLE_QUOTA_DIR repointed to a
   fresh dir + PYTEST_CURRENT_TEST forged      → STILL BLOCKED, resolves .graqle
3) internal=True (sanctioned tooling)          → ALLOWED

Wheel contents confirmed: reasoning_gate.py + reasoning_quota.py ship; the
sys.modules guard is present; the unconditional GRAQLE_QUOTA_DIR override is
gone; month-pruning is in; graqle/cloud/* and graqle/server/* are stripped
(0 entries each).

This closes the one verification gap I had flagged as outstanding: previously only the
wheel's contents were checked, never an actual install.

Ordering

private #325 (back-port of the paywall-bypass fix) was merged before #326, so the
release is cut from a private master that no longer contains the vulnerable
resolve_quota_dir(). Confirmed on private/master: unconditional override gone,
sys.modules guard present, version 0.83.0.

Rule #0

git remote -v run before push. Public cherry-pick authorised only because private
#326 is merged (2026-07-31T12:28:52, base advanced to 9fee93ac). Sequential gate
satisfied.

After merge

Tag v0.83.0 → PyPI publishes → MCP Registry auto-follows.

Known red: Release Gate (PyPI) — documented repo-wide infra flake (FileNotFoundError,
exit 2) that also failed on #243, #244 and #245, all of which merged. Needs an
owner-approved infra fix (empty GRAQLE_LICENSE secret); unrelated to this diff.
