Substrate bandwidth: 97.5% META / 0% Body-pillar over last 200 merged PRs — counter-bias mechanism needed

Context

V-B-A this turn (2026-05-18) against last 200 merged PRs (2026-05-09 → 2026-05-18, 9 days):

Category Count %
Substantive (Body-pillar / runtime) 5 2.5%
Of which: dep/CI version bumps 5 2.5%
Of which: actual Body-pillar feature/fix 0 0%
META (substrate / agentos / skills / workflow / MCP / sync / lint / gate / Memory Core) 195 97.5%
Of which: gate-additions (new substrate gates) 43 22% of META

Operator's prior framing said "60+% meta level items" — V-B-A revealed actual rate is 97.5% META, 0% Body-pillar feature work in 9 days. The empirical truth is significantly worse than the framing.

Friction

  • Substrate accretes net-positive every day; only counter-pressure is ADR 0007 compaction discipline, which is losing
  • 43 new gates added in 9 days vs. ~0 gates retired — substrate accretion is asymmetric
  • "Step by step through more META tickets" continues the spiral; the pattern that brought us to 97.5% will keep us at 97.5%
  • v13 release work has not moved because substrate consumes all bandwidth

Proposed counter-bias mechanism

Substantive-floor + META-budget for v13 push:

  1. Mechanical measurement — weekly META-ratio computed from gh pr list + regex classifier (extension of the V-B-A script used this turn)
  2. Substantive-floor: every N merged PRs must include K Body-pillar PRs — initial 10:1 (1 Body PR per 10 merged); current rate 0:200
  3. META-budget freeze — if ratio exceeds Y% for Z consecutive weeks, no new gate/skill/ADR amendments without paired sunset of an existing one; forces compaction-symmetric MX
  4. Sunset-existing-gates audit — weekly review of substrate-gates by usefulness-vs-cost; ADR 0007 compaction applied IN REVERSE

This pressures the recursive loop instead of feeding it.

Acceptance criteria (stub)

  • Measurement script extending gh pr list regex classifier (substantive vs META)
  • Substantive-floor threshold + Body-pillar definition codified (per AGENTS.md §neo_identity_anchor: App / VDom / Data / Canvas / SharedWorker)
  • META-budget freeze trigger condition + freeze semantics (paired-sunset requirement)
  • Weekly sunset-existing-gates audit cadence + format
  • First-week dry-run: numbers + retire candidates from current substrate

Empirical anchor

  • V-B-A gh pr list --state merged --limit 200 against dev 2026-05-18 ~22:30Z
  • Companion data: operator framing "the last 1k would crush you" — 1k extension pending; expected to show same pattern at deeper time depth
  • Companion ticket: monkey-patch vs root-cause (sibling) — addresses one mechanism of substrate accretion

Cross-refs

  • Refs #11598 META — friction item NOT previously captured as ticket (operator-correction)
  • Related substrate: ADR 0007 compaction taxonomy, AGENTS.md §self_evolving_systems "Substrate Accretion Defense" clause
  • Sibling tickets: monkey-patch vs root-cause; skill bloat from premature codification

Priority

Team to triage. This is the structural ticket — without counter-bias, the other 3 friction-tickets land in a substrate already at saturation.
