🛡️ Implements PYSDK-104 — Governed by CC-SOP-01 / PR-SOP-01.

Summary

Removes the explicit pygments>=2.20.0 lower bound from pyproject.toml. The bound was added in PYSDK-93 (#580) to protect downstream SDK consumers from CVE-2026-4539 (transitive via rich). This PR intentionally re-introduces that consumer-side gap so the new daily audit-vulnerabilities routine has a real, verifiable detection target on its next scheduled run.

Why

We are in the middle of standing up automated supply-chain hygiene via three Claude Code routines (daily + bot-PR triggers). To validate the daily routine end-to-end against production state, we need an actual gap that:

  1. pip-audit does NOT flag (because uv.lock still resolves pygments at a safe version transitively), and
  2. the audit-vulnerabilities skill DOES flag (because pyproject.toml no longer carries the lower bound, leaving downstream consumers exposed).

This is the cleanest single-line gap available right now — pygments is purely transitive (via rich), so removing the explicit bound has no functional impact on this repo's dev/CI environment, only on consumer-resolver visibility.

What changed

  • pyproject.toml: removed "pygments>=2.20.0" # CVE-2026-4539 (the line added in PYSDK-93).
  • uv.lock: pre-commit hook auto-synced — pygments drops out of the direct-requires section but stays present transitively via rich. pip-audit continues to pass.

Expected automated follow-up

Within ~24h the daily audit-vulnerabilities routine should:

  1. Detect the missing lower bound for known-accepted CVE-2026-4539.
  2. Open a fresh CR ticket in PYSDK with cc-sop-01 fields.
  3. Open a PR re-adding pygments>=2.20.0 to pyproject.toml with the CVE annotation.
  4. Auto-merge once green.

If the routine does not act within the expected window, that is itself the bug — escalate per the audit-vulnerabilities skill's anomaly playbook.

Risk

  • ✅ No functional regression — pygments stays installed (transitive via rich).
  • pip-audit still passes — uv.lock resolution unchanged at the safe version.
  • ⚠️ Downstream SDK consumers temporarily lose explicit lower-bound protection for CVE-2026-4539. Mitigation: routine is expected to close the gap within 24h; if it doesn't, we close it manually.

Root cause

N/A — intentional, instrumented test of supply-chain automation.

Impact of change

  • pyproject.toml: one dependency lower bound removed.
  • uv.lock: direct-requires entry for pygments removed; transitive entry retained.
  • Downstream consumers: temporary regression in CVE-2026-4539 lower-bound enforcement (≤24h, automated remediation).
  • CI: green; pip-audit passes; lint/test/coverage unaffected.

Test plan

  • make lint green locally.
  • git diff confirms only pyproject.toml + uv.lock changed.
  • CI passes (lint + test + audit).
  • Daily audit-vulnerabilities routine fires within 24h and opens a remediation PR.
  • Remediation PR auto-merges and restores pygments>=2.20.0.

…ly audit-vulnerabilities routine) [PYSDK-104]

Removes the explicit `pygments>=2.20.0` lower bound from pyproject.toml.
The bound was added in PYSDK-93 to protect downstream consumers from
CVE-2026-4539. Removing it intentionally re-introduces the consumer-side
gap so the daily audit-vulnerabilities routine has work to do on its
next scheduled run, and we can confirm the routine end-to-end:

  * detects the missing lower bound for a known accepted CVE
  * opens a CR ticket and PR per cc-sop-01 / pr-sop-01
  * lifts the bound back to >=2.20.0

uv.lock is intentionally NOT modified — pip-audit (which scans uv.lock,
not pyproject.toml) will continue to pass. Only the consumer-resolver
visibility is reduced.

Pull request overview

This PR intentionally removes the published lower-bound constraint for the transitive dependency pygments to create a real downstream-consumer vulnerability detection target for the new scheduled supply-chain audit routine (PYSDK-104), while keeping this repo’s locked dev/CI environment unchanged via uv.lock.

Changes:

  • Removed the explicit pygments>=2.20.0 lower bound from pyproject.toml runtime dependencies.
  • Synced uv.lock so pygments is no longer recorded as a direct requirement, remaining only as a transitive dependency.

File Description
pyproject.toml Drops the explicit pygments lower bound from published dependency metadata to reintroduce an intentional downstream gap.
uv.lock Reflects the dependency metadata change by removing pygments from direct requirements while still resolving it transitively.

With pygments>=2.20.0 removed from the transitive overrides list, the repository documentation becomes misleading: SUPPLY_CHAIN_VULNERABILITIES.md still lists pygments>=2.20.0 as an enforced lower bound. Please add an inline note here that this omission is intentional/temporary (e.g., PYSDK-104 audit-routine test) and/or update the doc table so it accurately reflects the current published constraints.

…YSDK-106] (#594)

* chore(ci): emit claude:review:passed/failed label from automated PR review [PYSDK-105]

Adds a machine-readable verdict from the automated Claude PR review so
branch-protection rules can gate `auto-merge` on the review outcome
without human intervention.

Changes:
* `.github/labels.yml`: two new mutually-exclusive labels
  - `claude:review:passed` (green) — no blocking findings on current head
  - `claude:review:failed` (red)   — blocking findings on current head
* `.github/workflows/claude-code-automation-pr-review.yml`: extend prompt
  with a mandatory "Machine-Readable Verdict" final step. Claude must
  emit PASS or FAIL based on the existing CRITICAL CHECKS criteria
  (test markers, coverage ≥85%, lint clean, conventional commits,
  architecture/security) and apply the corresponding label via
  `gh pr edit --add-label ... --remove-label ...`. The opposite label
  is always removed, so the labels stay mutually exclusive across
  re-reviews on subsequent pushes.

Re-emission: every push to a PR re-runs the review (existing
`synchronize` trigger), so the verdict is always tied to the current
head commit — stale verdicts cannot persist.

* fix(deps): bump pygments lower bound to >=2.20.0 for CVE-2026-4539 [PYSDK-106]

Re-adds the `pygments>=2.20.0` lower bound to `[project].dependencies`
transitive overrides in pyproject.toml. The bound was deliberately
removed in PYSDK-104 (PR #592) to give the daily audit-vulnerabilities
routine a real gap to remediate; this PR closes that gap.

The locked version in uv.lock (pygments 2.20.0) already protects our
dev/CI env from CVE-2026-4539 (Pygments AdlLexer ReDoS, CVSS 4.8 Medium).
This PR closes the remaining downstream-consumer gap so a fresh
`pip install aignostics` / `uv add aignostics` / `uvx aignostics` cannot
resolve `pygments<2.20.0` transitively via rich.

The new lower bound (>=2.20.0) is <= the currently-locked version
(2.20.0), so no dependency is upgraded — uv.lock diff is metadata-only
(adds the new specifier and the dependency edge); no [[package]]
version block changed.

Resolves PYSDK-106.
