+The org-required Strix workflow installs a complete hashed lock. Upstream
+`strix-agent==1.5.3` still declares `cryptography<49`, so compile-time
+override keeps `cryptography==50.0.0` (CVE-2026-69247 PKCS#7 timing

 ### Fixed
 
+- Pin required Strix to `strix-agent==1.5.3` so a completed scan writes a durable report artifact, keep `cryptography==50.0.0` (CVE-2026-69247 / CVE-2026-39892) via a compile-time override, and install the complete hashed lock with `--no-deps` so pip cannot re-apply the stale `cryptography<49` bound. The fail-closed missing-artifact gate is unchanged.
 - Materialized base Python locks only when every package line is an exact SHA-256 pin or a bounded relative `-r`/`--requirement` include. A lone `--require-hashes` directive, a dotted include such as `./lock.txt`, or `-r other-hashes.txt` no longer enters the trusted build context.
 - Refused a conflict-scope repository root whose immediate parent is a symbolic link, so a swapped parent cannot redirect the canonical worktree after the last-component check (CWE-367).
 - Bounded the Strix quality self-test's deterministic timeout fixtures to 3-second process and 5-second fake-sleep budgets so exact-head policy evidence completes inside the existing job limit without changing production Strix scanner timeouts, providers, credentials, or review semantics.

+# Strix 1.5.3 atomic report persist + cryptography 50 override
+
+검토 기준일: **2026-08-16**
+
+## Incident
+
+The required Strix check is the central `pull_request_target` /
+`repository_dispatch` workflow in this repository. On current `main`
+(`c47afc2dc68488292c1db7c9d6f82dcd5360f181`) consumer runs still install
+`strix-agent==1.0.4` with `cryptography==50.0.0`. Recent failures that
+were re-read for this increment, not only ContextualWisdomLab/.github#952:
+
+| Consumer | Run | Observed terminal shape |
+|---|---|---|
+| ContextualWisdomLab/mightyETL#315 | [31950271564](https://github.com/ContextualWisdomLab/.github/actions/runs/31950271564) / job 95172565509 | `Tool execute not found in agent strix`, then `No Strix vulnerability report artifact was produced; log-only severity markers are incomplete evidence` |
+| ContextualWisdomLab/.github#1023 | [31952135549](https://github.com/ContextualWisdomLab/.github/actions/runs/31952135549) / job 95177171349 | `Penetration test completed` / `Vulnerabilities MEDIUM: 1`, then exit 2 and `Strix report artifacts emitted warning/fatal/denied/timeout output; failing closed` |
+| ContextualWisdomLab/noema#392 | [31950935010](https://github.com/ContextualWisdomLab/.github/actions/runs/31950935010) | required `strix` red on the same 1.0.4 lock |
+
+The fail-closed missing-artifact rule in `scripts/ci/strix_quick_gate.sh`
+(ContextualWisdomLab/.github#891) is working as designed and is not
+weakened here. Console TUI lines such as `Vulnerabilities MEDIUM: 1` are
+not a passing report.
+
+The crash-after-print shape is the 1.0.4 scanner. Upstream 1.1.0 added
+atomic CSV/MD writes, and 1.4.0+ quit after scan instead of hosting a
+local viewer. Latest PyPI release remains `strix-agent==1.5.3` and still
+declares `cryptography>=48.0.1,<49` (usestrix/strix#859, Intel macOS
+universal2 wheel). See ContextualWisdomLab/.github#952.
+
+A one-line bump is blocked because `uv pip compile` without an override
+refuses `strix-agent==1.5.3` + `cryptography==50.0.0`. Cryptography 50.0.0
+is the floor that closes CVE-2026-69247 (PKCS#7 EnvelopedData
+Bleichenbacher-style timing/error oracle in `pkcs7_decrypt_der` /
+`pkcs7_decrypt_pem` / `pkcs7_decrypt_smime`, introduced in 44.0.0). It
+also sits above CVE-2026-39892 (non-contiguous buffer overflow, fixed in
+46.0.7).
+
+## Decision
+
+1. Pin `strix-agent==1.5.3` and keep `cryptography==50.0.0`. Materialize
+   only exact SHA-256 pins or a bounded relative `-r` include; a lone
+   `--require-hashes` line is not lock evidence.
+2. Resolve the declared upper bound only at compile time through
+   `requirements-strix-ci-overrides.txt` and
+   `scripts/ci/compile_strix_ci_lock.sh`.
+3. Install the complete hashed lock with
+   `pip install --require-hashes --no-deps`. The lock already lists every
+   wheel; `--no-deps` prevents pip from re-applying the stale
+   `cryptography<49` metadata bound that would otherwise make CI
+   uninstallable. Immediately after install, the workflow fail-closes
+   unless `importlib.metadata` reports `strix-agent==1.5.3` and
+   `cryptography==50.0.0`.
+4. Do not scrape console TUI lines as a substitute report. The gate still
+   requires a durable artifact and still fail-closes on warning / fatal /
+   denied / timeout report signals.
+
+A live `pip`/`uv` install of this hashed lock with `--require-hashes
+--no-deps` imported `strix`, ran `strix --help` (including the
+non-interactive “exits on completion” path), and loaded
+`cryptography==50.0.0` together with `strix-agent==1.5.3` on CPython
+3.12.3 and 3.13.15.
+
+## Trust boundary
+
+- The fail-closed missing-artifact rule is unchanged.
+- The override file may contain only `cryptography==50.0.0`.
+- Hashes remain required. `--no-deps` is not an unhashed install.
+- NVIDIA NIM / OpenCode credentials are untouched. This path never uses
+  `COPILOT_GITHUB_TOKEN`.
+
+## Verification contract
+
+`tests/test_strix_agent_cryptography_override.py` proves the input pin,
+the singleton override, both versions in the compiled lock, the compile
+script flags, the `--no-deps` install line, the post-install
+`strix-agent==1.5.3` / `cryptography==50.0.0` metadata check, and that
+quality CI retriggers when any of those files change.
+
+## Rollback
+
+If 1.5.3 regresses a required scan, revert the pin to 1.0.4 and the
+`--no-deps` install together. Do not drop cryptography 50.0.0 to satisfy
+the stale `<49` bound.
+
+## After merge
+
+Consumer required `strix` checks read this workflow from protected
+`main`. After this lands, a new same-head scan installs 1.5.3, persists
+the report directory, and lets the existing gate judge that artifact.
+Findings at or above `STRIX_FAIL_ON_MIN_SEVERITY` still fail the check.
+A completed scan with no threshold finding can go green.
