# LinkedIn Studio Plugin — Structure Validator
# Validates the REAL v3.1 layout: registration counts (derived dynamically),
# frontmatter shape, hook drift, and plugin.json fields. Counts are asserted
# against the declared contract below, which is kept in sync with the
# CLAUDE.md "## Agents (N)" / "## Commands (N)" headers (cross-checked here)
# and the STATE.md "Telling" block. Adding or removing an agent, command,
# reference, or skill breaks the count-equality and fails the lint — this is
# the registration guard that gates the remediation plan's later steps.
#
# The stat-consistency grep (one magnitude per algorithm effect across the
# tree) was added in remediation Step 3; the version-consistency grep in
# Step 21. Both are live below (Sections 8 and 9).
#
# Usage: bash scripts/test-runner.sh
# bash 3.2-safe: plain arrays only, no `declare -A`, no `mapfile`/`readarray`.

# The single source of truth for algorithm magnitudes is
# references/algorithm-signals-reference.md. After the Phase-0 reconciliation,
# stale/competing magnitudes — the retired engagement-coefficient folklore, the
# unpublishable model params/brand, and the deployment date — must not reappear
# anywhere else (cite the reference, do not restate). This enforces "one magnitude
# per algorithm effect" by forbidding EVERY retired-class value from returning, so
# the same grep that defines the Phase-0 Success Criterion fails on any survivor.
#
# S9 rebuild: the S8 list forbade only the two S7-named strings and went green
# over six more survivors (the coefficient system in analytics-interpreter/
# content-optimizer/pipeline/glossary, the playbook 15x/5x, the 150B model). This
# list is rebuilt to the FULL criterion. Forbidden classes (each maps to a
# canonical statement in the reference):
#   - Carousel-rate folklore:   6.6% / 6.60% / 1.92%      → reference: "~7% top format"
#   - Link-penalty folklore:    40-50% / 25-40% / -40-60% → reference: one ~38% correlational band
#   - Comment-multiplier folklore: "15x more reach/algorithmic", "5x more effective/
#       less valuable/reach than" → reference: order only, comment ≈ 2x a like
#   - Video-multiplier folklore: "5x more conversations"  → reference: video declining, no multiplier
#   - Engagement-coefficient system: 7-9x, 2.5x, 0.2x, (10x), (8x), "10x weight"
#       → reference: "never hard coefficients to optimize against"
#   - Model params/brand/date:  the PATTERN CLASS [0-9]+[ -]?(B|billion)?[ -]?param
#       (covers 150-parameter / 150B param / 150 billion param) / 360Brew / January 2026
#       → reference: "Not publishable as fact"
#
# S10: the model-precision token is now the pattern CLASS, not a literal-token
# list. S9 forbade only "150 ?B param|150 billion param"; a hyphenated
# "150-parameter" (no "B") slipped both the discovery grep and the lint, surviving
# in glossary.md:10. The criterion is "no asserted model precision in ANY surface
# form", so the lint now enforces the shape (a number adjacent to "param"), not an
# enumeration. An adjacent digit is REQUIRED, so legitimate "param" uses with no
# leading number — "Language parameter", "parameterized", "different parameters",
# "«parametere»", "175-milliarders parametermodell" — do not match.
# Bare "10x"/"15x"/"5x" are deliberately NOT forbidden — they carry legitimate
# uses (collaboration "10x your reach" hyperbole, "5x5x5", posting cadence, pixel
# dims like 1080x1350), so each token targets the retired *phrasing*, not the bare
# number.
#
# Scope covers every dir the criterion's grep covers, including assets/checklists/
# (the 360Brew survivor lived there, outside the S8 scan), assets/templates/, and
# CHANGELOG.md (S10: the 360Brew/January-2026 survivor lived there, outside the S9
# scope). assets/{templates,checklists}/ — not all of assets/ — keeps the scan off
# gitignored runtime data (assets/analytics/, assets/drafts/, voice-samples/).

# Non-vacuity self-test (S10). A grep criterion is only meaningful if it actually
# MATCHES the forbidden forms and does NOT match legitimate ones. S7→S9 each
# shipped a lint that passed green while a survivor slipped, because the proof was
# run once by hand and never committed — so a hyphenated "150-parameter" form was
# never re-checked. This makes the proof PERMANENT: it runs on every invocation
# BEFORE the real scan, so narrowing STALE_STATS back to a literal-token list fails
# the suite instead of silently certifying an unenforced criterion. The positive
# set covers all three model-precision surface forms (incl. the exact S10
# "150-parameter" survivor); the negative set covers the legitimate "param"/x uses
# that live in the tree today.
