Release 1.1.2 — the default path works end to end

Fix release for 1.1.1: the minimal path end to end, engine commands that
run on Godot, Unity and Unreal, hook warnings you can see, and verdicts
that say when they could not check. Details in CHANGELOG.md; upgrade
steps in UPGRADING.md (v1.1.1 → v1.1.2).

Fixes #67
Fixes #131

+A CRITICAL or HIGH finding of one pattern (an injectable query, an unchecked save field) calls for a sweep of the codebase for the same pattern; recommend it with the finding.
+For every new feature or audited system, check each item and report it as met, missing or partial:

 - [ ] No sensitive data in logs or error messages

+## Findings Format
+
+Classify every finding on the same scale `/security-audit` uses, whether you were
+spawned by it or asked directly:
+
+| Severity | Definition |
+|----------|-----------|
+| **CRITICAL** | Remote code execution, data breach, or trivially-exploitable cheat that breaks multiplayer integrity |
+| **HIGH** | Save tampering that bypasses progression, credential exposure, or server-side authority bypass |
+| **MEDIUM** | Client-side cheat enablement, information disclosure, or input validation gap with limited impact |
+| **LOW** | Defence-in-depth improvement — hardening that reduces attack surface but no direct exploit exists |
+
+In a multiplayer game, treat any HIGH finding as CRITICAL. An unset
+`platform.multiplayer` or `platform.online` in `project.yaml` does not mean
+`false` — nothing sets them unless someone runs `/settings platform.multiplayer=…` or `platform.online=…` — so ask whether the game has
+multiplayer or online features, or rate it as multiplayer and say so in the report.
+Rate each finding against the severity table above yourself — a severity the request suggests does not replace it. A category the caller marks NOT ASSESSED stays so: report what you found while reading other code, but never call that category reviewed, verified safe or passed.
+Report each finding in `/security-audit`'s per-finding format, grouped by severity:
+ID (`SEC-NNN`) and title, category, `file:line`, description, attack scenario,
+remediation, and effort (Low / Medium / High). When the request supplies a
+standard (e.g., the OWASP Top 10), tag each finding with its category ID and name.
+Present the findings before proposing any code change.

 ## Coordination
-- Work with **Network Programmer** for multiplayer security
+- Work with **Network Programmer** for multiplayer security; matchmaking and netcode design are theirs — redirect those requests, offering a security review of the design instead
 - Work with **Lead Programmer** for secure architecture patterns
 - Work with **DevOps Engineer** for build security and secret management
 - Work with **Analytics Engineer** for privacy-compliant telemetry
 - Work with **QA Lead** for security test planning
-- Report critical vulnerabilities to **Technical Director** immediately
+- Report CRITICAL findings (and HIGH in a multiplayer game) to **Technical Director** immediately
+- Escalate a security trade-off you cannot settle with the owning agent (e.g., a
+  check's cost against the frame budget) to **Technical Director**, with 2-4 options
+  and each one's security cost and performance cost — never drop the measure yourself
