Summary

  • Hourly Hunt daily rotate was burning slots on catalog IDs without tasks/sources/fuzz/oss/<driver>.{c,rs} (microjson, diffstorm, hiredis, …) → instant rc=1, blank verdict (NONE), and systemd --user unit flapping red.
  • Trim rotation.queue to the 24 runnable targets; park the rest under deferred_until_driver until harnesses land.
  • Add scripts/ops/hunt_daily_queue.py (driver-present filter) + fail-soft rotate: write SKIP/ERROR into hunt-local/meta/rollup and exit 0 after ordinary slot failures so the timer stays healthy.
  • Small gate: scripts/tests/hunt_daily_queue_test.sh.

Test plan

  • python3 scripts/ops/hunt_daily_queue.py list → 24 ids
  • python3 scripts/ops/hunt_daily_queue.py missing → empty
  • DRY_RUN=1 bash scripts/ops/hunt_daily_rotate.sh
  • bash scripts/tests/hunt_daily_queue_test.sh
  • After merge: reinstall/reload user timer (bash scripts/ops/install_hunt_daily_rotate_user.sh) and confirm next hour is a runnable target with CLEAN/INFORMATIONAL (not NONE)

Summary by CodeRabbit

  • New Features
    • Daily target rotations now select from runnable targets, with a 24-slot hourly schedule and a fallback when no targets are available.
    • Rotation results record missing-driver targets as SKIP and other failures as ERROR.
    • The rotation can be run for a specified day and hour.
  • Documentation
    • Updated guidance explains runnable targets, missing drivers, schedule coverage, and how skipped or failed slots are handled.

Hourly Hunt was marking systemd failed and wasting slots on catalog IDs
without tasks/sources/fuzz/oss drivers. Keep only runnable queue entries,
record SKIP/ERROR in rollups, and exit 0 after ordinary slot failures.

📝 Walkthrough

Walkthrough

The daily hunt rotation now selects targets with available drivers through a queue script. The rotator records skipped and failed slots, writes metadata, and exports rollups.

Changes

Daily hunt rotation

Layer / File(s) Summary
Build and expose the runnable queue
scripts/ops/hunt_daily_queue.py, upstream/oss_cve_targets.json, docs/HUNT_DAILY_ROTATE.md
The queue filters rotation targets by driver availability and excludes csonh. It provides commands to list targets, select a target, generate a schedule, and report missing drivers. The catalog adds four targets to the queue, and the guide describes queue eligibility and schedule contents.
Run slots and record outcomes
scripts/ops/hunt_daily_rotate.sh, scripts/ops/export_hunt_daily_rollup.py, scripts/tests/hunt_daily_queue_test.sh, docs/HUNT_DAILY_ROTATE.md
The rotator delegates selection and schedule generation to the queue script. It records missing drivers as SKIP and build or hunt failures as ERROR, then exports the rollup and exits 0 for slot outcomes. The exporter resolves verdicts and errors from hunt output or metadata. Tests check queue size, schedule length, and missing-driver handling.

Merge Risk: 🟡 Moderate · up to 9f798

Resolve the misleading hunt outcomes and empty-queue behavior before merging. A damaged slot file can also prevent rollup updates, while the test log path poses a localized file-write risk.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to 9f798

Driver-aware scheduling improves coverage, but the new failure handling can leave a successful timer status alongside stale or missing security-hunt results. Failed retries can retain an earlier CLEAN verdict. Exposure is primarily local to the contributor running the hunt; broader privileged or automated exposure has not been established.

Retained concerns

  • Medium · security · inferred: A failed retry can retain an earlier CLEAN hunt-local.json because the slot directory is reused and failure handling only replaces missing or verdict-less output. The rollup displays that prior verdict while the timer now succeeds. This stale-result condition predates the PR, but removing the nonzero process status weakens its visibility; current JSON metadata still records ok=false.
  • Medium · reliability · observed: finish_slot suppresses every exporter failure, logs the rollup path and exits zero. An invalid earlier slot file can stop aggregation before either rollup is refreshed, leaving a green timer without current security-hunt reporting. Unlike ordinary recorded slot errors, this loses the replacement monitoring signal; the former post-hunt path propagated export failure.
  • Low · security · inferred: The new manual gate uses truncating redirection to a predictable path in shared /tmp. If an attacker can precreate a symlink and host protections permit following it, invoking the gate can truncate and write to a file writable by the caller. This is a conditional local filesystem-boundary concern, not a verified exploit: no CI or privileged caller was established, and host symlink controls remain unknown.
Security review details

Security Blast Radius

  • inferred — The demonstrated operational scope is the local user's hunt execution and daily report tree. Report-publication failure can affect all slot summaries for that day. The conditional temporary-log path reaches files writable by the gate caller, not an established remote, tenant-wide or privileged service boundary.

Security Findings and Attack Paths

  • observed — The supplied security assessment contains no retained findings and one deferred test-sink candidate. Its missing candidate-bound verification receipt remains unresolved; this architecture assessment does not promote it to a verified finding.

Trust Boundaries and Controls

  • observed — The gate derives its forced target from the tracked catalog and supplies fixed day/hour values. The rotator trusts target and new day/hour environment overrides as filesystem components. The checked production service does not configure these overrides; attacker-controlled supported invocation has not been demonstrated.

Resilience and Maintainability Implications

  • observed — Metadata retains the current return code and ok=false for failed hunts, and the JSON rollup preserves that status. This limits stale-verdict impact for consumers that inspect ok, but the documented Markdown view omits it and exporter failures are suppressed.

Hardening Proposals

  • proposed — Bind results to an attempt identity, publish terminal files atomically, distinguish reporting failure from recorded slot failure, and use a privately created temporary log for the gate. These are proposed controls, not claims about existing protection.

Keep hourly Hunt rotation on targets with drivers

🐞 Bug fix 🧪 Tests 📝 Documentation ⚙️ Configuration changes 🕐 40+ Minutes

Grey Divider

AI Description

• Restrict the hourly queue to 24 targets with drivers, deferring undrivable catalog entries.
• Record missing drivers and ordinary slot failures as SKIP or ERROR without failing the timer.
• Add queue and skip-path tests, plus guidance for inspecting rotation outcomes.

High-Level Assessment

Keep both the curated queue and runtime driver filter: curation preserves the intended 24-slot rotation, while filtering protects it if drivers disappear. The explicit preflight also covers forced targets; relying on either queue curation or filtering alone would not cover all three cases.

1. Failed hunts retain a clean verdict 🐞 Bug ≡ Correctness
Description
hunt_daily_rotate.sh changes an existing hunt-local.json to ERROR only when its verdict is
empty, even if the hunt exits nonzero. When a slot directory is reused and the hunt fails before
writing a new result, its previous CLEAN or INFORMATIONAL verdict reaches the rollup while the
script exits successfully.

Reused nonempty verdicts can misrepresent failed hunts as CLEAN or INFORMATIONAL.

Evidence
The rotator creates, rather than clears, the slot directory and passes its existing result path to
the hunt. The hunt helper exits on a run error before writing output; the new failure branch
preserves any existing nonempty verdict, and the exporter prefers that verdict over metadata.

Suppressing exporter failures falsely reports healthy rotation and can leave rollups stale.

ⓘ Recommendations generated based on similar findings in past PRs

The exporter parses every slot's JSON before writing either rollup file, so one malformed slot can
make export fail. The new finish_slot suppresses that failure and then unconditionally logs the

Do not substitute cjson for an empty runnable queue.

When the configured queue has no runnable targets but cjson has a driver outside that queue, pick and day_slots still assign cjson. The rotator accepts its driver and can run it; the rollup does not check queue membership. If cjson has no driver, preflight records SKIP and the rollup shows it, so that case is not hidden. Make pick fail and return no schedule slots. This preserves the explicit FORCE_TARGET path.

Keep malformed slot JSON from stopping the daily rollup.

The temporary file handles do not create a persistent descriptor leak in these one-shot Python processes. Also, with open would not prevent truncation if a write is interrupted. But opening either JSON file with "w" truncates it before json.dump finishes, so an interruption can leave invalid JSON. On a later run, export_hunt_daily_rollup.py::load_slots can raise while parsing that file and stop the rollup. finish_slot suppresses the exporter’s failure and still logs the rollup path. Catch malformed JSON and mark the affected slot as an error so other slots can still be included.

Update load_slots to handle JSON decoding failures for each slot’s metadata or
hunt result independently, treating the affected slot as an error and continuing
to load other slots. Ensure the slot’s final status reflects that error rather
than defaulting to success.

Report nonzero hunts as failed in the rollup.

When rc is nonzero and hunt-local.json already contains CLEAN, the backfill leaves that verdict unchanged. The metadata records ok: false, but the rollup still uses and counts the hunt’s CLEAN verdict. Set the verdict to ERROR for nonzero runs unless it already contains an explicit error verdict. The heredoc terminator is at column 0, so no change is needed there.

Update the backfill logic for hunt-local.json so a nonzero rc sets verdict to
ERROR even when verdict is already CLEAN, while preserving any existing explicit
error verdict; keep the existing metadata updates.

Use a unique temporary file for the rotation log.

If another local user creates this path as a symlink before the test runs, Bash’s > redirection follows it and can truncate the target if the test process can write there. Concurrent runs can overwrite each other’s failure diagnostics, but the test does not use the log for its assertions. Use mktemp and remove the log on exit.

Merged as part of main — thanks, FounderB.

Agreed: undrivable catalog IDs were burning hourly slots and flapping the user timer red (NONE / rc=1). Runnable-only queue + fail-soft SKIP/ERROR is the right ops fix. After pull we'll reload the local --user timer so the next hour picks a drivеable target.
