Residual Deprecation Sweep — closing the 2026-05-31 audit 🧹

The deferred proliferation from Lanes 1–3: the same deprecated patterns in non-audited skills. 16 default sub-agents, one per skill, judgment-aware (no blind replace) + an aggregate gap-sweep. Off fresh main (both lanes merged).

What changed

68 files across 16 skills. Mechanical fixes applied everywhere they were real code; model-id modernization applied only to plain "use this model" defaults; everything specialized or deliberate was left and logged.

Left intentionally (judgment, not laziness)

  • gpt-5.2-codex ×20 (dedicated gpt-5-2-codex.md + its sibling rows) — specialized model; deferred to a separate codex-lineup pass rather than create an incoherent "gpt-5.5 standard beside gpt-5.2-codex" doc.
  • gpt-5.2-realtime / gpt-4o-transcribe ×2 — current specialized voice/transcription models; mapping them to gpt-5.5 would strip the capability.
  • gpt-3.5-turbo ×1 — a deliberate cheap/legacy fallback-tier cost illustration in a token-budget script.
  • z.string().email in zod-v4-api.md — these are comments documenting what the new form replaced (the code is already z.email()).

Audit status after this

Lane 1 (#2142) + Lane 2/3 (#2143) + this residual sweep = the entire 2026-05-31 library-currency audit remediated. Only the explicitly-deferred codex/realtime model-lineup verification remains (its own small pass).
