Readiness Scorecard

This chapter summarizes current release readiness by subsystem and ties the score directly to the current hardening ladder.

Overall Readiness

LINC should currently be read as:

  • strong on hermetic evidence production
  • strong on ELF-first symbol and validation workflows
  • useful but more conservative on Mach-O and Windows import-library paths
  • meaningfully hardened on vendored and daemon-style fixtures
  • still dependent on host availability for the largest OpenSSL and Linux-system ladders

For whole-pipeline claims, this score is also capped by downstream gerc anchors that ingest linc evidence in tests/examples.

For Level 1 production, this score should be read as Linux/ELF-first. Apple and Windows readiness should raise confidence, not redefine the primary production envelope.

Subsystem Scorecard

  • source-shaped intake: high
  • JSON artifact stability: high
  • ABI layout evidence: medium-high
  • symbol inventories: high for ELF, medium-high for Mach-O, medium for Windows
  • validation: medium-high
  • link planning: medium-high
  • hermetic large-surface confidence: high
  • host-dependent large-surface confidence: medium-high
  • consumer integration on the documented artifact boundary: high

Canonical Readiness Anchors

The release posture should be judged against these anchors first:

  • vendored zlib
  • vendored libpng
  • plugin ABI fixture
  • combined daemon fixture
  • difficult-record evidence fixtures
  • OpenSSL when available
  • Linux event-loop analysis when available

If those anchors drift, the scorecard should drop even if many smaller unit tests still pass.

How To Read This Scorecard

High means the subsystem is a reliable contract surface for normal downstream use. Medium-high means consumers should still respect the documented limits and expect some host/platform asymmetry. Medium means the subsystem is useful but should not be oversold as equally mature across all supported environments.
