Finding 1 — manifest bypassed sanitization and threat detection: moving the agent-authored manifest to the `manifest_final.json` file artifact removed it from gh-aw's `sanitizeContent` pass and from the auto-generated threat-detection job (which stages only the prompt, agent_output.json, and patches). Add a `safe-outputs.threat-detection` block to both twins that stages the manifest into the detection directory, names it in the detection prompt, and fails closed if a submission was authorized without it. Add a deterministic trusted-boundary rejection (`Test-HiddenOrControlContent`) that fails closed on control/DEL/C1 characters, bidirectional/invisible format characters, and HTML comment sequences in the raw agent body — rejecting rather than stripping so hash-verified evidence lines are never corrupted. Finding 2 — exact-once gates ignored `.errors`: gh-aw diverts rejected, duplicate, or argument-carrying submissions into agent_output.json's sibling `.errors` array, so a duplicate `submit_ci_scan` vanished from `.items` while the run still reported success. Reject a non-empty `.errors` in both the post-steps jq gate and `Assert-ScannerSubmissionFromAgentOutput`, and add `max: 1` to the custom submit-ci-scan safe-job for MCP-time defense in depth. Both changes are mirrored across the main and net11 twins; lock files were regenerated with `gh aw compile --strict`. Adds producer-shaped `.errors` regression tests, hidden/control-content body-rejection tests, a `no-hidden-content-rejection` mutation with load-bearing coverage, and workflow-source invariants for the new controls.

Expanded the reject set to also cover U+061C (Arabic letter mark), U+180E (Mongolian vowel separator), U+200B-200F, U+2028/2029 (line/paragraph separators), and the variation selectors U+FE00-FE0F. - Test-MarkerLikeContent tolerates invalid Unicode: NFKC normalization throws on unpaired surrogates, so fall back to the raw value and let the scalar-walk hidden-content gate reject it with a precise reason instead of an opaque exception. Marker-first ordering is preserved so invisible-character marker-evasion spellings are still caught. - Threat-detection manifest staging keys its fail-closed authorization decision off the download-independent needs.agent.outputs.output_types signal (env OUTPUT_TYPES) instead of the submit_count parsed from the continue-on-error agent_output.json download, so a transient artifact-download failure can no longer fail open. Mirrored in both twins; the threat-detection prompt now names variation selectors and Unicode tag characters explicitly. - Strengthened the no-hidden-content mutation test to assert the mutant actually publishes the reviewer-invisible comment (ok=true, body contains the literal comment), and added scalar-walk regression cases (astral tag/variation-selector chars, unpaired surrogate, BMP marks) plus an over-rejection guardrail accepting a legitimate astral emoji.

Invisible/format code points outside the enumerated ranges still passed the gate: musical (U+1D173-1D17A), interlinear annotation (U+FFF9-FFFB), shorthand format controls (U+1BCA0-1BCA3), and similar. Close the whole Unicode Format (Cf) category in one shot via CharUnicodeInfo.GetUnicodeCategory, after enumerating the invisible Mn/Lo code points (variation selectors, Mongolian FVS, CGJ, Khmer inherent vowels, Hangul fillers) explicitly so a blanket category reject cannot swallow legitimate accents (U+0301) or CJK. 2. Noncharacters (U+xFFFE/U+xFFFF per plane, U+FDD0-FDEF) fell through: they make NFKC normalization throw, so Test-MarkerLikeContent's raw-value fallback never folds a compatibility-spelled marker onto its real token -- letting a fullwidth marker + U+FFFE slip past the marker gate. Reject noncharacters here so this gate is the sound backstop for that fallback rather than a fail-open. Add discriminating regression coverage: Format-category, non-Format invisible, and noncharacter rejection cases; an over-rejection guardrail proving accents + CJK are still accepted; and a marker-smuggled-past-NFKC-folding test proving the noncharacter backstop blocks the fullwidth-marker evasion. Full Pester suite: 1370 passed, 0 failed. Shared script, so both scanner twins are covered; no lock recompile required and strict twin compile stays byte-stable.

This preserves ordinary agent-authored markers such as warning signs without reopening a generic variation-selector steganography channel after arbitrary symbols. Add symmetric positive and negative coverage for both presentation selectors, including warning-sign acceptance and rejection after text or a dollar symbol.
