Trust-but-verify: origin/release/v3.8.49 tip alone (pristine, no PR changes) already measures 2169 with node scripts/check/check-complexity.mjs — i.e. +39 is inherited cycle drift unrelated to this PR (the cyclomatic-complexity ratchet does not run on PR->release fast-gates). This PR's OWN growth adds exactly +1: per-file eslint scoped scan on open-sse/executors/hyperagent.ts (base vs PR) shows extractMessageText() crossing the complexity>=15 threshold for the first time (new violation, complexity 25) from the new Anthropic tool_use/tool_result flattening branches; resolveHyperAgentThreadBinding's existing pre-#8470 violation (18) grows to 25 (still counted once, from the new root-key lookup tier); createHyperAgentThread and execute() are unchanged pre-existing violations. Net repo-wide total = 2169 (inherited drift) + 1 (this PR's own new violation) = 2170. Full-repo re-measurement of the merged branch was attempted but not completed live due to heavy concurrent devbox load (many other /green-prs sessions running the identical full-repo eslint scan in parallel); derived from two independently-clean measurements (base-tip full scan + per-file base-vs-PR delta). Covered by tests/unit/executor-hyperagent.test.ts (19/19). Tighten via --update next cycle.",

OWNER-APPROVED TEMPORARY relax for v3.8.50-3.8.54 PREPARE phase (docs/ROADMAP.md). v1 was +124 (2x daily drift) on 2026-07-27; v2 = v1 +20% buffer = +218 \u2192 +586 total (cycle 2188 measured pristine \u2192 2774 ceiling). Justification: v3.8.50 release cut coincides with high-merge activity (33-PR Train 1D + ~37-PR Train 2 backlog + post-freeze re-home rebase churn); owner accepted enlarging the headroom so the entire PREPARE phase window (5 minor cycles: .50-.54) flows without per-PR rebaseline noise, given that re-tightening happens mechanically at v3.8.51 via #8675/#8700 decomposition work scheduled in .51 (Executor registry in-place + combo.ts decomposition per ROADMAP.md). RE-TIGHTENING MANDATORY in v3.8.51: target 2282 (shrink of 492 from structural extraction during #8675/#8700 decomposition campaigns + combo.ts split scheduled in .52, or via npm run quality:ratchet -- --update if natural shrink appears earlier). The 2282 floor still gives 94 units of post-tighten headroom vs the current pristine 2188. Tracked via roadmap issue (TO BE OPENED as part of this PR). Window: v3.8.50 (release cut, 2026-07-28 target) \u2192 v3.8.54 close (RE-TIGHTEN executed at v3.8.51 prep merge per ROADMAP.md). This entry is the LAST rebaseline in this file unless a measured regression appears. v1 entry retained below for audit trail.",
