Track libavformat RTMP session initialization state so teardown only writes a trailer after the muxer header succeeds. This avoids calling av_write_trailer() on partially initialized sessions when avio_open2() fails with Connection refused.
Add a fault-suite regression for libavformat RTMP connection refusal and update the summary helper to compute all_pass from the actual manifest size instead of a hardcoded seven-row expectation.
Verified by rebuilding cvmmap_streamer and rtmp_output_tester, reproducing the refused-connection path without a crash, and running ./scripts/fault_suite.sh successfully (8/8).
Switch acceptance/fault/release scripts to project-local .sisyphus evidence roots and remove parent-repo path assumptions.
Also harden deterministic behavior with run-id-derived port allocation and tuned fault thresholds so release gate pass and injected-failure flows remain stable in standalone execution.
This commit packages the standalone task-14 acceptance and task-15 fault-suite execution toolchain for downstream validation.
It includes all runnable harness scripts, helper utilities, and generated evidence captures so downstream behavior can be reproduced and reviewed independently from docs and core implementation.
Bundling these assets separately allows QA/automation workflows to validate runtime changes without dragging operational notes or release-gate documentation into the same review unit.
