assessFreshness aged only the entry's own source.verified stamp, so an
entry re-verified against an old source stayed green while a newer source
sat unnoticed (BP-SUB-001 was stamped 2026-07-31, a week after the
superseding-grade article of 2026-07-24 was published). The stamp
certifies the old source; it says nothing about the evidence.
- entries may carry corroborating sources[] with published dates
- new evidence-age rule: stale when the NEWEST published date across all
sources exceeds evidenceStaleAfterDays (default 365); re-verifying the
old source never clears it, only newer evidence does
- source.supersededBy marks a replaced source: stale regardless of stamp
- stale items now carry reasons[] (verified-age / no-verified-date /
superseded / evidence-age)
- BP-SUB-001 gains the 2026-07-24 context-engineering article as a
verified corroborating source (near-verbatim coverage). NOT added to
BP-MECH-*/BP-SIZE-001: own verification found no mechanism-choice or
size-limit content in the article, contrary to the brief's assumption.

The 'living' half of the v5.7 living knowledge base. Same hybrid split as the
optimization lens (Chunk 2b): a deterministic, byte-stable, unit-tested core +
a web/judgment command shell.
- scanners/lib/knowledge-refresh.mjs: pure assessFreshness(register,
{referenceDate, staleAfterDays=90}) — age-based fresh/stale classification of
source.verified; referenceDate injected (never reads the clock) → fully
deterministic. 15 tests.
- scanners/knowledge-refresh-cli.mjs: -cli (NOT an orchestrated scanner →
scanner count stays 15, suite byte-stable). Read-only — never writes the
register, never hits the network. --reference-date/--stale-after/--dry-run,
exit 0/1/3. 8 tests.
- commands/knowledge-refresh.md (opus): CLI stale-report → re-verify each stale
entry by re-reading its source.url → poll CC changelog + Anthropic blog →
apply ONLY human-approved writes, then re-validate the register. No unverified
claim is ever auto-written (Verifiseringsplikt). Web-driven → not byte-stable.
No new agent, no new orchestrated scanner. Docs/badges: commands 19→20,
tests 1068→1091 (20 lib + 32 scanner test files). self-audit A/A, readmeCheck passed.
