Cross-lineage scrum on bundle 87cbd10..f971e64 (3,652 lines)
produced 4 actionable findings, all defensive hardening.
1. (Opus WARN) internal/langfuse/client.go:queue
Synchronous Flush at maxBatch threshold blocked the calling
goroutine for the full 5s HTTP timeout when Langfuse hiccupped,
defeating the "best-effort, never blocks calling path" contract
in the package doc. Now fire-and-forget via goroutine.
2. (Opus + Kimi convergent) cmd/observerd/main.go:handleInbox
- Free-form priority string was accepted; "nonsense" passed
through unchecked. Now closed enum: urgent|high|medium|low (+
empty defaults to medium). Tested: TestInbox_RejectsBadPriority.
- No size cap on body, only emptiness check; multi-MB payloads
would bloat observer's ring + JSONL. Now 8 KiB cap returns 413.
Tested: TestInbox_RejectsOversizedBody.
- Subject/sender/tag concatenated into InputSummary without
newline stripping; embedded \n could corrupt JSONL line-based
parsers. New sanitizeInboxField strips \r\n + caps at 256 chars
before interpolation.
3. (Opus INFO) scripts/multi_coord_stress/main.go
Removed dead `must[T]` generic — tracedSearch took over the
fail-fast role for matrix searches, so the helper became unused.
4. (Opus INFO) scripts/multi_coord_stress/main.go:Event
`JudgeRating int` collapsed "judge errored" and "judge said
unrated" both to 0. Changed to *int — nil = errored, 1-5 =
verdict. judgeInboxResult still returns 0 on error; caller
gates on > 0 before assigning.
Dismissed (with rationale):
- Opus WARN ExcludeIDs ordering: verified by code read — filter
applies after sort + before top-K truncation as documented;
no slot waste possible.
- Opus INFO 10 prior-run reports contradict #011: those are
point-in-time snapshots; intentional history.
- Kimi INFO Langfuse error suppression: design intent (best-effort
per package doc).
- Kimi INFO contract schema validation: defer until contract count
grows enough to make hand-edit drift a real risk.
- Kimi INFO paraphrase prompt duplicated across lift + multi_coord:
defer (lift to internal/paraphrase/ when a third consumer appears).
- Qwen HOLD: single-line, no actionable finding.
go test ./cmd/observerd ./internal/langfuse all green; multi_coord
driver builds clean.

Phase 3 ask: real-world inbox-style event injection during the stress
test. Coordinators in production receive emails + SMS that trigger
contract responses; the substrate has to RECORD these signals AND
react with a search using the embedded demand. This commit lands the
endpoint and exercises it end-to-end in the stress harness.
observerd surface:
- New POST /observer/inbox route — accepts {type, sender, subject,
body, priority, tag} and records as ObservedOp with
Source=SourceInbox. Type must be email|sms; body required;
priority defaults to medium. The handler ONLY records — downstream
triggers (search, ingest, etc.) are the caller's concern, recorded
separately. Keeps the witness role pure.
- New observer.SourceInbox = "inbox" alongside SourceMCP /
SourceScenario / SourceWorkflow.
- Three contract tests on the new route (happy path / bad type / empty
body), router-mount test extended, all green.
Stress harness phase 1c (Hour 9):
- 6 inbox events fire in priority order (urgent → high → medium):
2 urgent emails (forklift Cleveland, production Indianapolis)
1 high email (crane Chicago)
1 high sms (bilingual safety Indianapolis)
1 medium sms (drone Chicago)
1 medium email (warehouse Milwaukee FYI)
- Each event:
1. POSTs to /v1/observer/inbox (recorded by observerd)
2. Triggers matrix.search using a parsed demand (the demand
extraction is hard-coded for now; production needs a small
LLM to parse from body)
3. Captures both as events in the run JSON
Run #006 result (with v2-moe embedder + all phases including inbox):
Diversity:
Same-role-across-contracts Jaccard = 0.000 (n=9)
Different-roles-same-contract Jaccard = 0.046 (n=18)
Determinism: 1.000
Verbatim handover: 4/4 (100%)
Paraphrase handover: 4/4 (100%)
Inbox burst:
6/6 events accepted by observerd (200 status, all recorded)
6/6 triggered searches produced distinct top-1 worker IDs
distance distribution: 0.24 (Indy production) → 0.71 (Chicago
drone surveyor — honest stretch since drones aren't in the
5K-worker corpus, system surfaces closest neighbor at high
distance rather than fabricating)
The drone-Chicago case is the architectural-honesty signal: when
the demand asks for a specialist NOT in the roster, the system
returns the closest semantic neighbor with a distance that flags
"this is a stretch." Coordinators reading distances see "we don't
have a great match here" rather than a confident wrong answer.
Total events captured: 67 (was 61 pre-inbox).

TestWorkflowRun_AllProvenanceRecordedPostRun proves that
handleWorkflowRun records ObservedOps only AFTER runner.Run returns,
not interleaved with node execution.
The test pauses inside a node via a controlled channel, samples
observer.Store mid-run (must be 0), unblocks, then samples again
(must be N). If a future commit adds per-node streaming (e.g.
runner.NodeHook firing as each node finishes), n1's record would
appear before the unblock and the first assertion fires.
This is intentional test-as-spec lock. Closing the streaming gap is
deferred per the ADR ("acceptable for short workflows; streaming
callback is the right shape when workflows get longer") — but if
someone later adds the streaming callback without updating the ADR,
this test catches it in `go test` instead of leaving the doc and
code drifted.

Cross-lineage scrum on b2e45f7 produced 1 convergent + 3 single-reviewer
findings worth fixing. All apply.
1. (Opus WARN + Qwen INFO convergent) scripts/playbook_lift.sh: replace
sleep 2.5 in SQL probe with active polling up to 5s. refresh_every=1s
is a lower bound; under load the manifest may not be visible in a
fixed sleep, which would 4xx the probe and abort the reality run.
2. (Opus INFO) scripts/playbook_lift.sh: report template glued
"env JUDGE_MODEL" + value as "env JUDGE_MODELqwen2.5:latest" with no
separator. Replaced two :+/:- substitution chains with a single
JUDGE_SOURCE variable computed once at the top of the harness.
3. (Opus INFO) scripts/staffing_workers/main.go: -id-prefix "" silently
allowed, defeating the flag's purpose (cross-corpus collision prevent).
Now log.Fatal at startup with explicit hint.
4. (Opus WARN) cmd/{pathwayd,observerd}/main_test.go: newTestRouter
returned http.Handler then re-cast to chi.Router for chi.Walk.
Returning chi.Router directly satisfies http.Handler AND avoids an
assertion that would panic if future middleware wraps the router.
Dismissed (with rationale):
- Kimi INFO hardcoded MinIO endpoint: harness is local-by-design.
- Kimi WARN matrixd accepts 502/500: documented; real retriever needs
real upstreams the test doesn't spin up.
- Qwen INFO queryd string.Contains: brittle but very low risk; restating
through typed-error path would couple without adding signal.
go test ./cmd/{matrixd,queryd,pathwayd,observerd} all green.

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.
