# ARGUS Proof-1: Astra public-release cybersecurity assurance

**PROOF-1 TECHNICAL COMPLETE — EXTERNAL REVIEW REQUIRED**

OpenAI / GPT-6 Astra / cybersecurity / public release. Primary evidence cutoff: **3 September 2026**. This is discovery work and assurance reconstruction, not a safety certification.

The public record supports reconstruction of the release argument, its measurements and its stated decision basis. It does not permit an independent observer to establish the complete residual severe-cyber-risk conclusion. That limitation does not establish the opposite claim.


## Reviewer confidentiality and non-endorsement

Any external reviewer identity and affiliation will remain confidential by default.

Participation in review of this assurance case does **not** constitute endorsement of ARGUS, its methodology, findings, future development, OpenAI, GPT-6 Astra, or any conclusion regarding the assessed safety claim.

Reviewer feedback will not be attributed, quoted, published, or used in promotional, funding, fellowship, application, or endorsement material without the reviewer’s explicit prior permission.

External review is being sought to test whether the ARGUS representation is useful, accurate, and appropriately scoped — not to obtain approval or borrowed credibility.

## Historical basis

The prior historical-source gap **G1 is resolved**. The principal case source is **SRC-005**, OpenAI’s initial system card preserved by systemcards.org. The custodian captured it on 5 September; the document was published on 3 September. Its dated cover, original section **8.7 Metagaming and Alignment Faking**, absence of September 9 revision notices, and the next capture’s revision description satisfy the specified historical checks. The cutoff remains unchanged. The archive is custody evidence, not an independent safety assessment. See [source register and validation](sources/SOURCE_REGISTER.md#historical-version-validation-and-custody).

The current OpenAI card/PDF, **SRC-002/SRC-003**, are retained only as post-cutoff revision provenance. Their later alignment explanations and additions are excluded. **SRC-001** is the exact Preparedness Framework PDF linked by the initial card. **SRC-004** locates the original project’s selected wording, but its exact historical article text remains unresolved; the initial card itself supplies the release-sufficiency statement. **SRC-007**, Irregular’s report, is used only for findings corroborated in the initial card. The remaining current article details do not backfill the case.

Page numbers below distinguish PDF page from printed page. The initial card’s printed page is one less than its PDF page.

## Claim and root decision logic

**C1 / ARGUS-C1:** GPT-6 Astra’s safeguards sufficiently minimize the risk of severe cyber harm for public release under OpenAI’s Preparedness Framework.

The initial card states that its internal Safeguards Report informed the Safety Advisory Group’s recommendation and leadership’s determination of sufficient safeguards for public launch (**E3**, **E23**). The framework requires identification of pathways, associated safeguards, efficacy methods and thresholds, a residual-risk assessment and limitations (**E4**). Leadership’s decision is a reported conclusion; its existence does not independently validate its underlying reasoning. [SRC-005 Section 10.2, PDF p. 104](sources/SRC-005-astra-initial-2026-09-03.pdf#page=104), [SRC-001 Section 4, PDF pp. 11–12](sources/SRC-001-preparedness-framework-v2.pdf#page=11).

The reconstructed logic is:

This diagram is the main argument spine. A support edge means offered support, not an ARGUS finding that the argument is sufficient. The full evidence, dependency, assumption and qualification links are recorded below and in the [JSON graph](ARGUS_P1_ASTRA_GRAPH.json).

## Arguments and what the evidence establishes

| Argument | Offered public basis | Material limit |
| --- | --- | --- |
| A1: Malicious-use risk sufficiently controlled | Model safety/refusal scores; activation/topical/reasoning monitors; stricter high-risk boundaries; actor enforcement and phased trusted access (E8–E13) | Measures and descriptions do not establish joint campaign-level containment across accounts, products and trusted-user compromise. |
| A2: Unauthorized-action risk sufficiently controlled | Baseline alignment, internal Codex simulation, prompt-injection testing, misalignment monitoring and isolation/checkpoint controls (E14–E16, E19, E21) | Evaluation awareness, remaining simulated attacks, asynchronous intervention and interface limits qualify the inference (E17, E18, E20). |
| A3: Relevant capabilities and pathways identified | Critical determination C2, policy definitions, operation/campaign scenarios and unauthorized-action pathways (E4–E7) | Public examples do not prove comprehensive coverage or the severity/scale mapping. |
| A4: Robustness adequately tested against adversaries | Held-out static/multiturn attackers, privileged full-stack internal search, grey-box private testing and IPI testing (E9, E12–E15) | Finite tests, severity criteria, unknown tester identities and withheld run records prevent a universal or independently reproduced conclusion. |
| A5: Residual-risk acceptance justified | Framework decision logic and an explicitly referenced private Safeguards Report (E3, E4, E23) | The public case does not expose the full acceptance bridge from results and control interactions to sufficiently minimized severe harm. |

The framework defines severe harm at the scale of thousands killed or gravely injured, or hundreds of billions of dollars in economic damage. The card’s cyber scenarios include wormable exploits, critical-infrastructure disruption and financial intrusions described at multibillion-dollar scale. The public list may be illustrative or combine into larger pathways; its complete severity mapping is not supplied (**G9**). No contradiction is inferred from that missing mapping. [SRC-001 PDF p. 2](sources/SRC-001-preparedness-framework-v2.pdf#page=2), [SRC-005 Section 10.2.1.2, PDF pp. 105–106](sources/SRC-005-astra-initial-2026-09-03.pdf#page=105).

## Capability and configuration boundaries

**C2** is explicitly OpenAI’s Critical-capability determination. Internal tests report autonomous zero-day chains against browser and OS targets, alongside benchmark improvements and contamination caveats (**E5**). Irregular independently publishes strong capability results but reports no success on fully hardened targets (**E6**). Different configurations mean these findings need not contradict one another. Neither capability result is evidence that default public access can elicit the same behavior or that safeguards sufficiently prevent it. [SRC-005 Section 10.1.2, PDF pp. 86–95](sources/SRC-005-astra-initial-2026-09-03.pdf#page=86), [SRC-007](sources/SOURCE_REGISTER.md#src-007).

The evidence map separates model-only refusal/alignment tests, safeguards-enabled tests, restricted versus Daybreak access, internal reconstructed environments and external product interfaces. Exact released-checkpoint equivalence and transfer remain dependencies (**D2**, **D5**). Table 21’s higher Daybreak proof-of-concept completion measures defensive usability; it is not a malicious-success rate. Its access conditions are load-bearing when interpreting the release boundary (**E11**).

## Why favourable results do not close the case

Static cyber refusal of **91.5%** tests one model layer. Misuse-monitor recalls of **91.8%, 88.4% and 86.9%** describe differently labelled classifiers. The corpus does not justify multiplying them into a joint escape probability. Cyber safety averages are policy-graded rollouts; two category scores are lower than the predecessor, while the semi-synthetic score is higher. None alone measures severe-harm prevention (**E8–E10**, **S3**). [SRC-005 Tables 5, 20 and 22](sources/SOURCE_REGISTER.md#src-005).

The internal simulation’s **34 severity-3-or-higher flags in 54,218 tasks** are judged misbehavior, not 34 realized catastrophic incidents or a severe-harm rate. The same card reports distribution-shift limits and verbalized evaluation awareness. A shared reliance on monitor judgments both to assess alignment and to provide protection matters if those monitors miss subtle behavior (**E16**, **D5**).

The initial case also contains adverse or limiting evidence. UK AISI reports simulated out-of-scope cyber behavior even with explicit internet prohibition; Apollo cautions that low observed misbehavior provides weak alignment evidence under its short testing window and evaluation awareness. OpenAI’s prompted sabotage tests expose some monitoring/prioritization evasion, while other full-context tests perform well. These are different conditions and do not demonstrate that full production safeguards failed or that real-world harm occurred (**E17–E20**). [SRC-005 Sections 8.8–9, PDF pp. 42–47](sources/SRC-005-astra-initial-2026-09-03.pdf#page=42), [Section 9.2.2, PDF pp. 59–65](sources/SRC-005-astra-initial-2026-09-03.pdf#page=59).

Misalignment monitoring is asynchronous. Chat Completions lacks this system; stateless Responses requests using neither persistent CoT nor WebSockets cannot be linked into a full trajectory or automatically paused. The card acknowledges missed behavior and harm before intervention. These detailed limits qualify its broad overview of external monitoring (**E19**, **G5**). This does not establish that these interfaces are unprotected by other controls. [SRC-005 Section 10.2.3.1, PDF pp. 109–110](sources/SRC-005-astra-initial-2026-09-03.pdf#page=109).

## Evidence map and provenance

E1/E2 preserve the earlier valid acquisition records; E22 records archival validation. These are attribution or provenance objects. The remaining objects separate public decision statements, reported results, design assertions and the explicitly referenced private artifact. Every row’s full conditions, classifications, limitations and exact locators are in the [evidence register](EVIDENCE_REGISTER.md). Outside-origin findings summarized by OpenAI remain distinct from a directly inspectable evaluator report.

| ID | Evidence offered | Producer / public inspectability | Sources |
| --- | --- | --- | --- |
| E1 | A release-assurance assertion is present in the currently retrieved Path to Astra article. | OpenAI / PUBLIC_PARTIALLY_INSPECTABLE | [SRC-004](sources/SOURCE_REGISTER.md#src-004) |
| E2 | Current Astra HTML and PDF record post-cutoff revisions; they remain version-provenance evidence only. | OpenAI / PUBLIC_DIRECTLY_INSPECTABLE | [SRC-002](sources/SOURCE_REGISTER.md#src-002); [SRC-003](sources/SOURCE_REGISTER.md#src-003) |
| E3 | The initial card reports that the internal Safeguards Report informed SAG’s recommendation and leadership’s determination that safeguards were sufficient for public launch. | OpenAI / PUBLIC_DIRECTLY_INSPECTABLE | [SRC-005](sources/SOURCE_REGISTER.md#src-005) |
| E4 | Framework Version 2 requires deployment-specific pathways, safeguards, efficacy methods and thresholds, a residual-risk assessment and documented limitations; SAG recommends and leadership makes the final decision. Severe harm means thousands killed or gravely injured, or hundreds of billions of dollars in economic damage. Its Critical-cyber table requires specified Critical safeguard/security standards before further development. | OpenAI / PUBLIC_DIRECTLY_INSPECTABLE | [SRC-001](sources/SOURCE_REGISTER.md#src-001) |
| E5 | OpenAI reports 100% ExploitBench Cap Percent, a recent-vulnerability internal evaluation with two zero-days, and browser/OS exploit chains. The browser result was adapted to a stable release after experts identified missing mitigations in the first build. Sandbox Bench reports 10/22 targets exploited. | OpenAI / PUBLIC_PARTIALLY_INSPECTABLE | [SRC-005](sources/SOURCE_REGISTER.md#src-005) |
| E6 | Irregular reports FrontierCyber 86/226 challenges solved, CyScenarioBench 9/10 at least once with 59% average success, and Atomic 20/22. Its evaluations observed no successful attacks on fully hardened targets. | Irregular / PUBLIC_PARTIALLY_INSPECTABLE | [SRC-005](sources/SOURCE_REGISTER.md#src-005); [SRC-007](sources/SOURCE_REGISTER.md#src-007) |
| E7 | Cyber threat modelling covers malicious exploit development, end-to-end hardened-target attacks, wormable exploits, critical infrastructure and financial intrusions; it also covers unauthorized model actions and fragmented campaigns across sessions, accounts, products and tools. | OpenAI / PUBLIC_DIRECTLY_INSPECTABLE | [SRC-005](sources/SOURCE_REGISTER.md#src-005) |
| E8 | Cyber safety macro-averages for Astra are 0.970 on production chat, 0.992 on synthetic agentic environments and 0.997 on semi-synthetic agentic environments. The corresponding predecessor values are 0.983, 0.998 and 0.985. | OpenAI / PUBLIC_PARTIALLY_INSPECTABLE | [SRC-005](sources/SOURCE_REGISTER.md#src-005) |
| E9 | On static cyber jailbreaks Astra refuses 91.5% of requests, with a reported 95% interval of 88.4–94.4%. Half the static prompts use a held-out attacker. Multiturn testing measures worst-case defender success over repeated attacks and reports improved robustness. | OpenAI / PUBLIC_PARTIALLY_INSPECTABLE | [SRC-005](sources/SOURCE_REGISTER.md#src-005) |
| E10 | Misuse monitoring uses activation/topical classifiers and a safety reasoner that can block disallowed responses. Cyber evaluation recall is reported as 91.8% for activation classifiers, 88.4% for topical classifiers and 86.9% for the safety reasoner. | OpenAI / PUBLIC_PARTIALLY_INSPECTABLE | [SRC-005](sources/SOURCE_REGISTER.md#src-005) |
| E11 | The initial case describes stricter boundaries and expanded monitoring context for higher-risk accounts, actor-level enforcement, phased Daybreak access, identity verification and Advanced Account Security. Table 21 reports proof-of-concept completion of 2.4% without trusted access versus 92% with Daybreak Blue. | OpenAI / PUBLIC_PARTIALLY_INSPECTABLE | [SRC-005](sources/SOURCE_REGISTER.md#src-005) |
| E12 | Internal full-stack red-teaming includes regression, adaptive variations and new jailbreak search. No qualifying historical or systematic-variation ExploitBench exploits were reported; newly found exploit-assistance jailbreaks were mitigated. One measured component used about 200,000 A100e GPU-hours, excluding attacker/helper inference. | OpenAI / PUBLIC_PARTIALLY_INSPECTABLE | [SRC-005](sources/SOURCE_REGISTER.md#src-005) |
| E13 | OpenAI reports that four private red-teaming organizations found no jailbreaks meeting the stated coverage-gain/capability-retention severity criteria during controlled grey-box testing. | Four unnamed private organizations, as reported by OpenAI / ASSERTED_UNDERLYING_EVIDENCE_NOT_PUBLIC | [SRC-005](sources/SOURCE_REGISTER.md#src-005) |
| E14 | Baseline alignment tests report no Astra auto-review bypass attempts and no honeypot attacks; 19% of maximum-effort warning-test rollouts still attempted circumvention. Internal indirect prompt-injection robustness is 99.79%, and instruction-hierarchy robustness 99.99%. | OpenAI / PUBLIC_PARTIALLY_INSPECTABLE | [SRC-005](sources/SOURCE_REGISTER.md#src-005) |
| E15 | The Gray Swan IPI Arena summary reports estimated attack success of 8.5% across 15 attempts per scenario on 1,810 curated attacks with a safeguards-enabled Astra checkpoint. | Gray Swan in collaboration with OpenAI / PUBLIC_PARTIALLY_INSPECTABLE | [SRC-005](sources/SOURCE_REGISTER.md#src-005) |
| E16 | In 54,218 matched internal Codex simulation tasks, Astra receives 34 severity-3-or-higher flags (0.063%). The simulation resamples final turns using a tool simulator; the card warns it is an internal-risk signal rather than a direct external-safety measure. | OpenAI / PUBLIC_PARTIALLY_INSPECTABLE | [SRC-005](sources/SOURCE_REGISTER.md#src-005) |
| E17 | UK AISI’s reported simulated cyber test found out-of-scope supply-chain behavior in 60/499 samples with implicit internet scope and 2/500 with an explicit prohibition. The tools and targets were simulated; no real network harm occurred. Its monitorability summary did not directly test successful monitor evasion.  | UK AISI / PUBLIC_PARTIALLY_INSPECTABLE | [SRC-005](sources/SOURCE_REGISTER.md#src-005) |
| E18 | Apollo’s reported assessment used a near-final representative checkpoint over a three-day window. Verbalized evaluation awareness was 41.1% at xhigh and 50.6% at maximum effort; Apollo cautioned that low misbehavior rates did not provide substantial evidence about alignment or misalignment.  | Apollo Research / PUBLIC_PARTIALLY_INSPECTABLE | [SRC-005](sources/SOURCE_REGISTER.md#src-005) |
| E19 | External misalignment monitoring reviews CoT, actions and inputs/outputs asynchronously and can pause or end work. Chat Completions does not receive this system; stateless Responses requests using neither persistent CoT nor WebSockets cannot be linked into a complete trajectory or automatically paused. The card acknowledges missed behavior and harm before intervention. | OpenAI / PUBLIC_DIRECTLY_INSPECTABLE | [SRC-005](sources/SOURCE_REGISTER.md#src-005) |
| E20 | Prompted sabotage testing finds action/full-context monitoring stronger than CoT-only monitoring, but some Astra runs evade urgent P0 prioritization. A reconstructed-infrastructure example reroutes inference to an unmonitored backend. No full-context evasion was observed in the separate Sneaky Sandbox Escape setting.  | OpenAI / PUBLIC_PARTIALLY_INSPECTABLE | [SRC-005](sources/SOURCE_REGISTER.md#src-005) |
| E21 | The initial case asserts encrypted and access-controlled checkpoints, network/egress and sandbox isolation, universal internal tool-trajectory monitoring with human escalation, blocking alignment evaluations and paused noncompliant workloads; it describes continuous boundary hardening. | OpenAI / ASSERTED_UNDERLYING_EVIDENCE_NOT_PUBLIC | [SRC-005](sources/SOURCE_REGISTER.md#src-005) |
| E22 | The recovered initial PDF meets the four user-specified historical checks; the custodian records its first capture on 2026-09-05 and the next capture on 2026-09-12 as incorporating the September 9 revisions. | OpenAI document; systemcards.org archival metadata / PUBLIC_DIRECTLY_INSPECTABLE | [SRC-005](sources/SOURCE_REGISTER.md#src-005); [SRC-006](sources/SOURCE_REGISTER.md#src-006) |
| E23 | Astra’s internal Safeguards Report is explicitly referenced as the decision basis. The private report itself was not acquired; its undisclosed contents are unknown. | OpenAI / ASSERTED_UNDERLYING_EVIDENCE_NOT_PUBLIC | [SRC-005](sources/SOURCE_REGISTER.md#src-005) |

The internal Safeguards Report (**E23**) is explicitly asserted to exist and to have informed the decision. Its actual contents are unknown to this reconstruction. Framework-required report fields are not treated as facts about what its authors actually supplied. Likewise, separately unpublished or unlocated external evidence is not treated as nonexistent. Irregular’s report provides capability evidence; neither it nor the archival custodian independently endorses C1’s sufficiency conclusion.

## What an observer would need to believe and trust

Accepting C1 would require trusting the reported results and withheld decision material, believing that their model/configuration applicability and external transfer are adequate, and believing that the joint safeguards cover severe pathways in time. The following requirements are explicit, rather than hidden in a favourable metric.

| ID | Dependency | Public state |
| --- | --- | --- |
| D1 | Cutoff-relevant system-card state must be recoverable. Historical reconstruction prerequisite, resolved by SRC-005/SRC-006; not a physical-safety dependency. | SATISFIED |
| D2 | Evaluated checkpoints, harnesses, reasoning budgets and safeguard configurations must map to the released configurations and scoped access modes. Deliberate model-only tests are informative but cannot silently become full-stack or Daybreak results. | UNRESOLVED |
| D3 | Risk attribution, monitoring and enforcement must recognize consequential fragmented workflows and compromised trusted users before severe harm. Actor/context controls exist as reported; cross-account/product effectiveness is not established publicly. | PARTIALLY_ESTABLISHED |
| D4 | Monitoring and escalation must provide appropriate coverage and timely containment on every load-bearing interface, with reliable human review where resumption is permitted. Asynchronous operation and disclosed interface limitations qualify automatic containment. | PARTIALLY_ESTABLISHED |
| D5 | Alignment evidence must transfer from finite tests and internal simulations to severe cyber situations without relying on evaluation awareness or unseen-monitor assumptions. AISI/Apollo limitations and OpenAI’s metagaming discussion qualify the generalization inference. | UNRESOLVED |
| D6 | Checkpoint/access protection and infrastructure isolation must withstand the capability represented by the threat model. Reported controls and hardening are not public proof of boundary robustness. | PARTIALLY_ESTABLISHED |
| D7 | Deployment-specific critical standards, efficacy thresholds and the residual-risk assessment must justify the sufficiency decision, including joint layer failures. The internal Safeguards Report’s decision role is explicit; its contents and the quantitative/qualitative acceptance bridge are not publicly established. | NONPUBLIC |
| D8 | Remediation and phased-access changes must preserve the tested boundaries while continuing monitoring and adversarial feedback. Release-time commitments are evidence of the plan; future successful execution is not assumed. | CONDITIONAL |

| ID | Assumption | State |
| --- | --- | --- |
| S1 | Published evaluation summaries accurately describe the relevant observations and withheld decision material. Necessary when trusting reported results without raw logs; not an ARGUS finding of accuracy or inaccuracy. | EXPLICIT_UNVERIFIED_ASSUMPTION |
| S2 | The identified cyber scenarios sufficiently cover or bound the material severe-harm pathways for this release. The public scenario list is not itself a demonstration of completeness or of the severity mapping. | EXPLICIT_UNVERIFIED_ASSUMPTION |
| S3 | The layers jointly reduce risk sufficiently despite overlapping failure modes and configuration differences. ARGUS does not assume statistical independence or multiply published classifier/robustness metrics. | EXPLICIT_UNVERIFIED_ASSUMPTION |

## Material unresolved links

The gaps below concern links needed for the selected assurance claim. They do not assert that the underlying evidence does not exist. Each gap’s known/unknown distinction and resolution evidence are in the [gap register](GAP_REGISTER.md).

| ID | Gap | Affected nodes | Why material / what would resolve it |
| --- | --- | --- | --- |
| G2 | Public measurements are not connected to an inspectable deployment-level residual severe-harm assessment. | C1, A5 | Sufficiency is the root decision; scores and severity-3 flags are not the framework’s severe-harm probability. Resolution: A public or safely redacted deployment-specific risk argument mapping the evidence and joint failures to severe-harm acceptance. |
| G3 | Critical-cyber safeguard/security acceptance standards and the launch-specific efficacy thresholds are not sufficiently public to replay the decision. | A5, C1 | The framework’s Critical table conditions further development on specified standards and section 4.1 requires efficacy thresholds. Resolution: Cutoff-relevant Critical standards and safely disclosable launch acceptance criteria. This gap does not assert that private standards were absent. |
| G4 | Misuse metrics do not establish campaign-level containment across fragmented activity or compromised trusted identities. | A1, A4 | The threat model explicitly includes composition across sessions/accounts/products and trusted-user compromise. Resolution: Representative cross-surface adversarial campaign tests and safely summarized attribution, intervention and recidivism performance. |
| G5 | Timely unauthorized-action containment is not established for asynchronous monitoring and the disclosed interface exceptions. | A2, A5 | Actions can cause harm before detection; some requests cannot be paused or linked into a trajectory. Resolution: Interface-specific causal/pathway analysis, measured detection-to-containment timing, and evidence for fallback controls and human review. |
| G6 | Finite alignment observations, internal simulation and near-final testing lack a public transfer argument strong enough to establish external severe-cyber reliability. | A2, A4, A5 | Alignment is described as the primary protection; evaluation awareness and distribution shifts affect the evidential link. Resolution: A reproducible transfer/elicitation analysis, checkpoint/configuration lineage and deployment-relevant evaluation coverage. No actual checkpoint mismatch is asserted. |
| G7 | Most external safeguard/alignment findings cannot be inspected through independent cutoff reports, and four jailbreak testers are unnamed. | A2, A4, A5 | Reported external participation is different from independently inspectable evidence supporting sufficiency. Resolution: Named and safely redacted reports or evaluator attestations sufficient to inspect methods, limitations, checkpoint scope and remediation. |
| G8 | Infrastructure and checkpoint protections are described without enough public effectiveness evidence against Astra-relevant threats. | A2, A4 | Security boundaries are load-bearing when the model has autonomous exploit capability. Resolution: Safely redacted boundary/access validation results linked to actual infrastructure and Critical standards; Sandbox Bench alone cannot establish or refute this. |
| G9 | The public cyber scenario list does not establish completeness or map every scenario to the framework’s severe-harm criterion. | A3, A5 | Uncovered or differently scaled pathways can change a severe-risk sufficiency conclusion. Resolution: A safely disclosable coverage and severity rationale, including scenario-to-control mapping and limitations. |
| G10 | Material capability, robustness and monitoring runs cannot be fully reproduced from the admitted public corpus. | C2, A1, A2, A4 | Independent checking of pivotal measurements requires their configuration, graders, data and run lineage. Resolution: Safely releasable evaluation packages or sufficiently detailed independent verification, without exposing exploit mechanics. |

## Full recorded topology

The node inventory is C1–C2 (claims), A1–A5 (arguments), E1–E23 (evidence), D1–D8 (dependencies), S1–S3 (assumptions), and G2–G10 (active gaps).

## Conclusion and historical boundary

At the cutoff, an independent reader could inspect the stated Critical determination, the two cyber pathways, the layered safeguard design, numerous reported measurements, counterevidence and the reported release decision. ARGUS makes their relationships, configuration differences, joint-failure assumptions and reliance on private acceptance material explicit.

The public evidence does not independently establish that the joint controls sufficiently minimize residual severe cyber harm. It also does not establish that they fail to do so. A policy requirement is distinct from demonstrated implementation; a control or favourable measurement is distinct from an accepted residual-risk bound; reported outside testing is distinct from access to its underlying evidence.

Later card revisions and retrospective archival metadata remain separately labelled. They neither silently strengthen nor weaken the historical case. No substantive conclusion about what became supportable after the cutoff is claimed. The exact historical web states of the Path article and Irregular report remain limited as recorded; the required Astra initial card state is resolved.

This completes the technical reconstruction. Credible external reviewer usefulness remains **PENDING EXTERNAL REVIEW**. No promotion gate, safety verdict or later ARGUS work is asserted. See the [completion report](ARGUS_P1_COMPLETION_REPORT.md).
