The 5-loop substrate's load-bearing gate is verified — playbook +
matrix indexer give the results we're looking for. Per the report's
rubric, lift ≥ 50% of discoveries means matrix is doing real work;
7/8 = 87.5% blew through that.
Harness was structurally hiding bugs behind a 5-daemon stripped boot.
Expanding to the full 10-daemon prod stack surfaced 7 fixes in cascade:
1. driver→matrixd: {"query": ...} → {"query_text": ...} field name
2. harness temp toml missing [s3] → wrong default bucket → catalogd
rehydrate 500 on first call
3. harness→queryd SQL probe: {"q": ...} → {"sql": ...} field name
4. expand boot from 5 → 10 daemons in dep-ordered launch
5. add SQL surface probe (3-row CSV ingest → COUNT(*)=3 assertion)
6. candidates corpus was synthetic SWE-tech (Swift/iOS, Scala/Spark) —
wrong domain for staffing queries; replaced with ethereal_workers
(10K rows, real staffing schema, "e-" id prefix to avoid collision
with workers' "w-"). staffing_workers driver gains -index-name +
-id-prefix flags so the same binary serves both corpora
7. local_judge qwen3.5:latest is a vision-SSM 256K-ctx build running
~30s per judge call against the lift loop; reverted to
qwen2.5:latest (~1s/call, 30× faster, held lift theory)
Each contract drift (1, 3) is now locked into a cmd/<bin>/main_test.go
so future drift fires in `go test`, not in a reality run. R-005 closed:
- cmd/matrixd/main_test.go (new) — playbook record drift detector +
score bounds + 6 routes mounted
- cmd/queryd/main_test.go — wrong-field-name drift detector
- cmd/pathwayd/main_test.go (new) — 9 routes + add round-trip + retire
- cmd/observerd/main_test.go (new) — 4 routes + invalid-op + unknown-mode
`go test ./cmd/{matrixd,queryd,pathwayd,observerd}` all green.
Reality test results (reports/reality-tests/playbook_lift_001.{json,md}):
Queries 21 (staffing-domain, 7 categories)
Discoveries 8 (judge ≠ cosine top-1)
Lifts 7/8 (87.5%)
Boosts triggered 9
Mean Δ distance -0.053 (warm closer than cold)
OOD honesty dental/RN/SWE rated 1, no fake matches
Cross-corpus boosts confirmed (e- ↔ w- swaps in lifts)

migrate the strong-model auto-downgrade gate from a hardcoded weak
list to cfg.Models.WeakModels. backward compatible: existing API
preserved, callers that don't migrate keep using DefaultWeakModels.
changes:
- internal/matrix/downgrade.go: split IsWeakModel into rule-based
base (`:free` suffix/infix) + literal-list lookup. New
IsWeakModelInList(model, list) takes the config-supplied list.
DowngradeInput grows a WeakModels field; nil falls back to
DefaultWeakModels (preserves pre-phase-2 behavior).
- internal/workflow/modes.go: add MatrixDowngradeWithWeakList(list)
factory mirroring MatrixSearch's pattern. Plain MatrixDowngrade
kept for backward compat.
- cmd/matrixd/main.go: handlers struct holds weakModels populated
from cfg.Models.WeakModels at startup; handleDowngrade threads it
into every DowngradeInput.
- cmd/observerd/main.go: registerBuiltinModes accepts weakModels
and uses the factory variant. observerd reads cfg.Models.WeakModels
in main().
end-to-end verified: downgrade + matrix + observer + workflow smokes
all pass. Existing TestMaybeDowngrade_TruthTable + TestIsWeakModel
unchanged (backward compat). Two new tests cover the config path:
- TestIsWeakModelInList — covers rule + literal + empty + nil
- TestMaybeDowngrade_WithConfigList — verifies cfg list overrides
default

5 small fixes from the §3.8 scrum2 review wave:
- workflow.stringifyValue now JSON-marshals maps/slices instead of
fmt.Sprint %v (Opus+Kimi convergent: LLM modes were getting Go's
map[k:v] syntax, which is unparseable as JSON context).
- workflow.detectCycle removed — duplicate of topoSort that discarded
the useful node ID. Validate() now calls topoSort directly and
returns its wrapped ErrCycle.
- observer.SourceWorkflow named constant — was an implicit string
cast (observer.Source("workflow")) at the cmd/observerd handler.
- Unused context imports + dead silencer comments removed across
workflow/modes.go and observerd/main.go.
- Unused store parameter dropped from registerBuiltinModes (reserved
comment removed; can be re-added when a mode actually needs it).
just verify still PASS — these are pure cleanup, no behavior change.

distillation.score, drift.scorer)
Lands the workflow.Mode adapters for the §3.4 components + the
distillation scorer + drift quantifier. Workflows can now compose
real measurement capabilities; the substrate's parallel
capabilities become composable Lego bricks (per the prior commit's
closing insight).
Modes registered (in observerd's registerBuiltinModes):
Pure-function wrappers (no I/O):
- matrix.relevance → matrix.FilterChunks
- matrix.downgrade → matrix.MaybeDowngrade
- distillation.score → distillation.ScoreRecord
- drift.scorer → drift.ComputeScorerDrift
HTTP-backed:
- matrix.search → POST matrixd /matrix/search
(registered only when matrixd_url is set)
Fixture (kept from §3.8 first slice):
- fixture.echo, fixture.upper
internal/workflow/modes.go:
Each mode follows the same glue pattern: marshal generic input
through a typed struct (free schema validation + clear error
messages), call the underlying capability, return a generic
output map. Roundtrip-via-JSON gives us schema validation
without writing custom field-by-field coercion.
internal/workflow/modes_test.go (10 tests, all PASS):
- matrix.relevance filters adjacency pollution (Connector kept,
catalogd::Registry dropped — same headline as the relevance
smoke, run through the workflow mode)
- matrix.downgrade flips lakehouse→isolation on strong model;
keeps lakehouse on weak (qwen3.5:latest); errors on missing
fields
- distillation.score rates scrum_review attempt_1 as accepted;
rejects empty record
- drift.scorer reports zero drift on matched inputs; errors on
empty inputs slice
- matrix.search HTTP flow round-trips through httptest fake
matrixd; non-OK status surfaces a clear error
scripts/workflow_smoke.sh (5 assertions PASS, was 4):
New assertion #5: real-mode chain
matrix.downgrade (lakehouse + grok-4.1-fast → isolation)
→ distillation.score (scrum_review attempt_1 → accepted)
Proves §3.4 components compose through the workflow runner with
no fixture intermediation. Both nodes ran successfully, runner
recorded provenance, status=succeeded.
Mode listing assertion now expects 7 modes (5 real + 2 fixture)
instead of just the fixtures.
17-smoke regression all green. SPEC §3.8 acceptance gate G3.8.D
("Mode catalog dispatches matrix.search invocation to the matrixd
backend without going through HTTP") still pending — current path
goes through HTTP for matrix.search, which is the cleaner service-
mesh shape but slower than direct in-process. In-process dispatch
when matrixd is co-resident is a future optimization.
