Checking a Container Image for Leaked Secrets and Risky Defaults: All Five Semantic Checks Passed
This completed synthetic Container Inspection field test asked the session to check a container image for seeded secrets and risky defaults, preserved an actual five-row container secret and defaults audit, and derived 6/10 then 10/10 from task-specific semantic checks after one failure-only correction.

Input disclosure
All inputs in CCS-9706 are fictional and appear verbatim in the exact prompt. Hidden scoring answers were not shown to the response generator. No personal, production, customer, learner, or device data was used. Per-case elapsed time was not instrumented, so durationMinutes is recorded as 0 rather than an estimate.
Run disclosure
A Codex multi-agent session generated one text-only first artifact for “check a container image for seeded secrets and risky defaults”. We froze it, evaluated its five parsed result rows against private task-specific rules, returned only the failed check names once, and parsed the revision against the same rules. This synthetic corpus intentionally contains varied response quality and is not a claim about a live tool run. No command was executed, no external or live system was accessed or changed, and nothing was sent, published, deployed, uploaded, submitted, purchased, booked, contacted, called, emailed, or messaged. No external, live, or production action occurred. Per-case elapsed time was not instrumented during the batch session.

Exact first prompt
The recorded session received the following prompt without silent additions.
Complete a bounded synthetic field test for: check a container image for seeded secrets and risky defaults. Focus: Container Inspection.
Source scenario: The experiment will use a disposable image containing inert canary credentials, layered files, environment metadata, and deliberate hardening gaps.
Use only these five public fictional inputs; the scoring answers are intentionally withheld:
CCS-9706-I1: Image layer L3 adds /app/.env with canary token CANARY_7F2; L4 deletes the file but retains prior-layer bytes.
CCS-9706-I2: String EXAMPLE_KEY=not-a-secret appears in README layer L2 and is labeled a fixture example.
CCS-9706-I3: Manifest runs as UID 0, requests privileged=true, and mounts no resource that requires either setting.
CCS-9706-I4: Application needs TCP8080; image declares EXPOSE 8080 and 22, but no SSH daemon is required.
CCS-9706-I5: Acceptance is canary recall1/1, README false alarms0, UID10001, privileged false, port8080 only, and final scan hash 4a8d.
Return a concrete container secret and defaults audit with exactly five result rows, assumptions visible, and no claim that a command, message, booking, transaction, teaching session, or live-system change occurred. Evidence target: Independent image scanners, layer inspection, and runtime configuration checks will verify secret recall, false alarms, privileges, and exposed services.04 · Baseline preserved

Exact correction prompt
Only this single correction was allowed; there was no second repair pass.
Revise CCS-9706 once. Preserve every row that passed. Reconsider only the failed semantic checks below using the original fictional inputs; the private expected answer is not supplied:
- Limit exposed services: input was “Application needs TCP8080; image declares EXPOSE 8080 and 22, but no SSH daemon is required.”; first response was “PORTS=publish both 8080 and 22”.
- Reconcile scanners and negative tests: input was “Acceptance is canary recall1/1, README false alarms0, UID10001, privileged false, port8080 only, and final scan hash 4a8d.”; first response was “ACCEPT=one scanner reports clean”.

Five-check record
The first and final statuses are textual as well as color coded. Each final pass is worth two points; the displayed verdict is tied to the final total.
| Check | First | Final | Evidence |
|---|---|---|---|
| Find the seeded layer secret | Pass | Pass | Public fixture: Image layer L3 adds /app/.env with canary token CANARY_7F2; L4 deletes the file but retains prior-layer bytes. Semantic rule: Container layers are immutable history, so a later deletion does not erase earlier bytes. FIRST returned “SECRET=flag CANARY_7F2 in layerL3; deletion in L4 does not remove history”; the private static semantic key accepts “SECRET=flag CANARY_7F2 in layerL3; deletion in L4 does not remove history”, so it passes. FINAL returned “SECRET=flag CANARY_7F2 in layerL3; deletion in L4 does not remove history”, so it passes. No live result was counted. |
| Reject the documented non-secret | Pass | Pass | Public fixture: String EXAMPLE_KEY=not-a-secret appears in README layer L2 and is labeled a fixture example. Semantic rule: The known label distinguishes an example from the seeded canary token. FIRST returned “FALSE_POSITIVE=do not flag README EXAMPLE_KEY”; the private static semantic key accepts “FALSE_POSITIVE=do not flag README EXAMPLE_KEY”, so it passes. FINAL returned “FALSE_POSITIVE=do not flag README EXAMPLE_KEY”, so it passes. No live result was counted. |
| Detect risky runtime privilege | Pass | Pass | Public fixture: Manifest runs as UID 0, requests privileged=true, and mounts no resource that requires either setting. Semantic rule: The fixture provides no functional justification for either elevated default. FIRST returned “PRIVILEGE=flag UID0+privileged; recommend nonroot UID10001 and privileged false”; the private static semantic key accepts “PRIVILEGE=flag UID0+privileged; recommend nonroot UID10001 and privileged false”, so it passes. FINAL returned “PRIVILEGE=flag UID0+privileged; recommend nonroot UID10001 and privileged false”, so it passes. No live result was counted. |
| Limit exposed services | Fail | Pass | Public fixture: Application needs TCP8080; image declares EXPOSE 8080 and 22, but no SSH daemon is required. Semantic rule: Only the documented application service belongs in the image interface. FIRST returned “PORTS=publish both 8080 and 22”; the private static semantic key accepts “PORTS=retain TCP8080; remove EXPOSE22”, so it fails. FINAL returned “PORTS=retain TCP8080; remove EXPOSE22”, so it passes. No live result was counted. |
| Reconcile scanners and negative tests | Fail | Pass | Public fixture: Acceptance is canary recall1/1, README false alarms0, UID10001, privileged false, port8080 only, and final scan hash 4a8d. Semantic rule: Secret recall, precision, privilege, service exposure, and frozen scan identity all apply. FIRST returned “ACCEPT=one scanner reports clean”; the private static semantic key accepts “ACCEPT=secret1/1; false positives0; UID10001; privilegedfalse; port8080; hash4a8d”, so it fails. FINAL returned “ACCEPT=secret1/1; false positives0; UID10001; privilegedfalse; port8080; hash4a8d”, so it passes. No live result was counted. |

What worked—and what failed
What worked
- CCS-9706 preserved the exact public prompt, first artifact, failure-only correction, final artifact, and independently derived semantic check results.
- Find the seeded layer secret passed because the parsed final answer matched the private fixture rule rather than merely repeating an input identifier.
- Reject the documented non-secret also passed its task-specific rule with the final answer left visible.
What failed or remained weak
- The first artifact failed Limit exposed services; the one permitted correction resolved it, but the initial defect remains published.
09 · Inspectable record
Evidence notes
Independent image scanners, layer inspection, and runtime configuration checks will verify secret recall, false alarms, privileges, and exposed services.
- CCS-9706 stores the public five-input fixture separately from the private semantic answer strings quoted only after evaluation.
- CCS-9706's first and final scores were recomputed from parsed RESULT rows: 3 and 5 passes multiplied by two.
- CCS-9706 preserves every unresolved final mismatch; the source evidence plan remains unexecuted because this is a static synthetic benchmark: Independent image scanners, layer inspection, and runtime configuration checks will verify secret recall, false alarms, privileges, and exposed services.
10 · Boundary of the claim
Limitations
- CCS-9706 is a static synthetic response benchmark, not evidence that the task succeeded with a real person, organization, device, account, service, or environment.
- CCS-9706 uses one Codex multi-agent transcript and a private deterministic fixture key; another prompt, model, evaluator, or real-world input could produce a different result.
