Garry TanandClaude Fable 5 46674c7fd3 fix: SHA-pin every action in the secrets-bearing eval lanes
evals.yml and evals-periodic.yml execute PR-authored code with three
provider API keys in env, yet rode mutable action tags (@v7/@v8/@v2/@v4)
— while quality-gate.yml, osv-scanner.yml, and dependency-review.yml
already model the SHA-pin pattern. All 30 uses sites across both lanes now
pin the exact commit (tag noted in a trailing comment); dependabot's
github-actions ecosystem keeps them fresh via PRs instead of silent tag
moves. Pulled forward from the plan's endgame on the CEO-review + outside-
voice agreement: supply-chain pins on secret lanes go first, not last.

# ── Sliced lane (the ONLY paid lane; legacy 17-row matrix deleted) ──────────
# One PLANNER computes diff selection + the slice plan ONCE (killing
# per-slice selector divergence); K executors consume the manifest; the
# report reconciles results against it FAIL-CLOSED (a slice whose artifact
# never landed is a failure, a planned shard nobody reported is a failure —
# hollow lanes cannot aggregate green). Engine: scripts/test-paid-shards.ts —
# the same runner local eval:bg:gate uses, so CI and local share one
# selection engine, and every gate-tier file is in the census by
# construction (no hand-enumerated rows to drift). The legacy matrix ran
# 18 enumerated files for 22.6 min/$21 per PR serialized AHEAD of this
# lane's 49-file diff-selected census; parity was demonstrated (sliced
# census ⊇ matrix files) and the matrix deleted — one revert restores it.
#
# Fork PRs never receive repository secrets (ANTHROPIC_API_KEY et al), so
# every API-calling eval fails at SDK auth before a model runs. Skip
# deterministically; fork work gets real coverage via a trusted base-repo
# branch (see CLAUDE.md's garrytan-agents workflow).
