A full T3 scaffold (change + plan workspace, ~7290 tokens) was created for every branch-start that omitted --tier, even for small changes that never read it. - agent-branch-start.sh: default tier T1 (notes.md only); GUARDEX_OPENSPEC_TIER default + normalize_tier fallback both T3->T1. Prints an escalation hint on T1. - agent-branch-merge.sh: pin the integration lane to T3 (it is inherently cross-cutting and needs the plan workspace) so the merge flow is unaffected. - Usage text + tier-guide docs (AGENTS.md, .agent/CLAUDE-CODE-WORKFLOW.md) updated. Tests: new 'DEFAULTS to T1' in branch.test.js; merge-workflow test fixed via the T3 pin. No-new-failures vs base (and one baseline failure now passes). Follow-up: auto-escalate when an agent writes proposal.md/spec.md into a T1 change.

Flip the default OpenSpec tier from T3 (~7290 tokens of change+plan scaffolding) to T1 (notes.md only) for branch-starts that omit
--tier; escalate explicitly with--tier T2/T3. Thegx mergeintegration lane is pinned to T3 (cross-cutting, needs the plan workspace). Usage + tier-guide docs updated.Gate: independent review clean (no CRITICAL/HIGH); failing-test set has zero NEW failures vs base (22 vs 23 — one baseline failure now passes). Baseline-red repo, manual gate.
Follow-up (tracked): auto-escalate when an agent writes proposal.md/spec.md into a T1 change.
