Production-readiness gauntlet exploiting the dual Rust/Go
implementation as a measurement instrument.
## Phase 1 — Full smoke chain
21/21 PASS in ~60s. Substrate intact across the full service surface.
## Phase 2 — Per-component scrum (token-volume fix)
Prior wave (165KB diff): Kimi 62 tokens out, Qwen 297 → no useful
analysis. This wave splits today's commits into 4 focused bundles
(36-71KB each):
c1 validatord (46KB) → 0 convergent / 11 distinct
c2 vectord substrate (36KB) → 0 convergent / 10 distinct
c3 materializer (71KB) → 0 convergent / 6 distinct (Opus emitted
a BLOCK then self-retracted in same response)
c4 replay (45KB) → 0 convergent / 10 distinct
Reviewer engagement vs prior wave: Kimi went 62 → ~250 tokens out
once bundles dropped below 60KB.
scripts/scrum_review.sh hardening:
* Diff-size guard (warn >60KB, hard-fail >100KB,
SCRUM_FORCE_OVERSIZE=1 override)
* Tightened prompt — file path must appear EXACTLY as in diff
so post-processor can grep WHERE: lines reliably
* Auto-tally step dedupes by (reviewer, location); convergence
counts distinct lineages (closes the prior `opus+opus+opus`
false-convergence bug)
## Phase 3 — Cross-runtime validator parity probe (the headline finding)
scripts/cutover/parity/validator_parity.sh sends 6 identical
/v1/validate cases to Rust :3100 AND Go :4110, compares status+body.
Result: **6/6 status codes match · 5/6 body shapes diverge.**
Rust returns serde-tagged enum: {"Schema":{"field":"x","reason":"y"}}
Go returns flat exported-fields: {"Kind":"schema","Field":"x","Reason":"y"}
Both round-trip inside their own runtime; a caller swapping one for
the other would break parsing silently. Captured as new _open_ row
in docs/ARCHITECTURE_COMPARISON.md decisions tracker.
This is the "use the dual-implementation as a measurement instrument"
return — single-repo scrums can't catch this class of cross-runtime
drift.
## Phase 4 — Production assessment
ship-with-known-gap. Validator wire-format gap is documented, not
regressed. ~50 LOC future fix on Go side (custom MarshalJSON on
ValidationError to match Rust's serde shape).
Persistent stack config (/tmp/lakehouse-persistent.toml) gains
validatord on :3221 + persistent-validatord binary so operators
bringing up the persistent stack get the new daemon automatically.

`jq --arg` and `curl --data-binary @-` both read stdin/argv-bound
buffers. Diffs >~128KB blow past the kernel's argv limit even when
piped via stdin (because we still build `body` as a shell variable
first, then feed it to curl). Voice-ai full bundle was 156K and
hit it.
Switch to writing user/system/body to mktemp files, jq reads via
--rawfile, curl reads via @file. Same on-the-wire shape, no argv
involvement. Cleanup with rm at the end.

Phase 4-bundle review (128KB diff) hit "Argument list too long" when
curl --data was passed the body as a literal arg. Pipe via stdin
with --data-binary @- instead. Lifts the practical bundle size from
~30KB to whatever fits in process memory.
Caught while running the harness scrum on golangLAKEHOUSE today —
the bigger Phase A+B harness diff (4566 lines) tripped it.

Bash driver wrapping /v1/chat for Opus + Kimi + Qwen3-coder review
runs. Used today to scrum the 4-phase wave (1,624 LoC of chatd +
config-refactor + Rust cleanup) and caught 2 BLOCKs + 2 WARNs.
Usage:
./scripts/scrum_review.sh <bundle.diff> <bundle_label>
Output: reports/scrum/_evidence/<DATE>/verdicts/<bundle>_<reviewer>.md
verbatim, per the evidence-only convention. Per-reviewer latency +
token counts captured in the report header.
System prompt enforces the BLOCK/WARN/INFO + WHERE/WHAT/WHY shape
per feedback_cross_lineage_review.md — leads with verdict, no
preamble (Kimi tends to spend tokens thinking otherwise).
Reviewer fleet matches project_golang_lakehouse.md "Scrum routing":
- opencode/claude-opus-4-7
- openrouter/moonshotai/kimi-k2-0905
- openrouter/qwen/qwen3-coder
This is the first dogfood of chatd as the scrum vehicle — eats its
own /v1/chat dispatcher.
