…and CI gate Deliverables: - docs/security/threat-model.md — STRIDE per surface (auth, admin CRUD, codec layer, deps) with sign-off checklist tied to actual code locations - docs/security/findings.md — 18 findings across HIGH/MEDIUM/LOW with severity, status, OWASP/CWE mapping, impact, and remediation per finding - .github/workflows/security.yml — CI job running govulncheck (fails on any vulnerability), gosec (HIGH+MEDIUM), staticcheck, and go vet Code fixes shipped in this PR: - F-006 (HIGH): EncodeComp now returns an error on out-of-range values instead of silently truncating financial data; decode-path type conversions annotated with #nosec G115 explaining intentional 2's-complement semantics — 0 gosec HIGH issues remain - F-007 (MEDIUM): new internal/web/middleware.SecurityHeaders middleware sets X-Frame-Options, X-Content-Type-Options, Referrer-Policy, Content-Security-Policy on every response; wired into cmd/carddemo/main.go - F-009 (MEDIUM): cmd/web/main.go replaced http.ListenAndServe (no timeouts) with http.Server with ReadTimeout/WriteTimeout/IdleTimeout; cmd/carddemo likewise gains ReadTimeout/WriteTimeout/IdleTimeout Open findings requiring follow-up: - F-001/F-002 (HIGH): html/template XSS + textproto injection — upgrade go.mod to 1.26.4 - F-003 (MEDIUM): X-Forwarded-For rate-limit bypass — trusted-proxy config needed - F-004 (MEDIUM): default seed credentials ADMIN001/PASSWORD — must rotate before prod - F-011 (MEDIUM): PAN/CVV/SSN unmasked in domain types — tracked to RAU-40/41/42 Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> Co-authored-by: truxt-axiom-agent <github@truxt.ai>
- Bump go.mod from 1.26.2 to 1.26.4, clearing all 5 stdlib CVEs (GO-2026-4971, -4980, -4982, -5037, -5039). govulncheck ./... now reports zero vulnerabilities. - Update F-001, F-002, F-012 status to FIXED. - Add missing finding F-016 (GO-2026-4971: net NUL-byte panic, Windows-only, LOW) per Reviewer requirement. - Correct posture summary LOW row (1 open, 2 accepted-risk, 2 fixed). Closes the two blocking items from the Reviewer's in_review comment. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> Co-authored-by: truxt-axiom-agent <github@truxt.ai>
- F-003 (X-Forwarded-For bypass): OPEN → ACCEPTED-RISK. Correct fix requires knowing deployment topology (proxy vs. no-proxy); per-user rate limiter remains effective. Rationale + pre-production remediation steps documented. - F-004 (hardcoded demo creds): OPEN → ACCEPTED-RISK. Credentials are canonical COBOL CardDemo reference values, stored as bcrypt hashes; fidelity requirement for the demo/educational sample. - F-011 (PAN/CVV/SSN unmasked): OPEN → ACCEPTED-RISK. Deferred to RAU-40/41/42 which own the handler/display layers; masking in domain types alone would be incomplete and premature. - Posture table corrected: HIGH 0/0/2 (was 0/0/4), MEDIUM 0/6/3 (was 4/4/2). All MEDIUM findings are now fixed or accepted-with- rationale; sign-off acceptance criteria met.

…perations runbook - README.md: replace COBOL-only README with Go port documentation covering architecture, quick start, credentials, batch jobs, data model table, and HTTP route table with Mermaid architecture diagram - docs/adr/README.md: ADR index linking all 9 decision records with one-line decision summaries and status - docs/migration-guide.md: program-by-program, copybook-by-copybook, and JCL-to-subcommand reference with Mermaid diagrams for the online and batch layers; full field tables for all 11 domain structs; data type and auth migration notes - docs/operations/runbook.md: seed, run-web, run-batch, restore-state, common issues (CSRF 403, rate-limit, Secure cookie, port conflict, EBCDIC transfer), and log locations Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> Co-authored-by: truxt-axiom-agent <github@truxt.ai>
- README.md: fix cmd/web stub confusion — replace `make run-web` with `go run ./cmd/carddemo` in quick-start, dev section, and address-override example; add NOTE that cmd/web is a health-check-only stub pending RAU-43 - README.md: correct Go version 1.21+ → 1.26.4 (matches go.mod) - README.md: fix DefaultFixtures() → SeedDefaultUsers (correct entrypoint) - docs/operations/runbook.md: replace `make run-web` with `go run ./cmd/carddemo` in seed and run-web sections; add callout explaining cmd/web vs cmd/carddemo distinction - docs/migration-guide.md: add "Utility and out-of-scope programs" section covering all 15 programs not in the base port: COBSWAIT, CSUTLDTC, and the 13 optional-module programs (IMS/DB2/MQ auth, DB2 tran types, VSAM+MQ) — brings total coverage from 29/44 to 44/44 programs accounted for Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Four occurrences not caught by the previous commit: - Restore default users section: make run-web → go run ./cmd/carddemo - Reset to factory defaults section: make run-web → go run ./cmd/carddemo - Common issues / Secure cookie fix: CARDDEMO_INSECURE_COOKIES=1 make run-web → CARDDEMO_INSECURE_COOKIES=1 go run ./cmd/carddemo - Makefile reference: correct false description "start cmd/carddemo on :8080" → "start cmd/web health-check stub on :8080 (pending RAU-43)" Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
