From 4458c94f45f8d6f7378c66ecd21081a57700de58 Mon Sep 17 00:00:00 2001 From: profit Date: Wed, 22 Apr 2026 17:33:24 -0500 Subject: [PATCH 01/26] =?UTF-8?q?tests/real-world:=20enrich=5Fprd=5Fpipeli?= =?UTF-8?q?ne=20=E2=80=94=20architecture=20stress=20test?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Real end-to-end test of the Lakehouse pipeline at scale. Runs the PRD (63 KB, 901 lines → 93 chunks) through 6 iterations with cloud inference, intentional failure injection, and tight context budget to force every Phase 21 primitive to fire. What the test exercises: - Sidecar /embed for 93 chunks (nomic-embed-text) - In-memory cosine retrieval for top-K per iteration - Tree-split (shard → summarize → scratchpad → merge) when context chunks exceed the 4000-char budget - Scratchpad truncation to keep compounding context bounded - Cloud inference via /v1/chat provider=ollama_cloud (gpt-oss:120b) - Injected primary-cloud failure on iter 3 (invalid model name) + rescue with gpt-oss:20b — proves catch-and-retry isn't dead code - Playbook seeding per iteration (real HTTP against gateway) - Prior-iteration answer injection for compounding (not just IDs — the first version passed IDs only and the model ignored them) Live run results (tests/real-world/runs/moamj810/): 6/6 iterations complete, 42 cloud calls total, 245s end-to-end tree-splits: 6/6 (every iter overflowed 4K budget) continuations: 0 (no responses hit max_tokens) rescues: 1 (iter 3 injected failure → gpt-oss:20b → valid answer) iter 6 answer explicitly cites [pb:pb-seed-82e1] — compounding real scratchpad truncation fired on iter 6 as designed What this PROVES: - Tree-split primitives work under real context pressure, not just in unit tests. The 4000-char budget forced every iteration to shard 12 chunks → 6 shards → scratchpad → final answer. - Rescue on primary failure is wired and produces answers from a weaker model rather than erroring out. - Compounding context injection works: iter 6's prompt had the 5 prior answers in its citation block, and the cloud model acknowledged at least one via [pb:...] notation. - The existence claims in Phase 21 (continuation + tree-split) are backed by executable evidence, not just unit tests. What this DOESN'T prove (deliberate — scoped for follow-up): - Continuation retries (no iter hit max_tokens in this run; would need a harder prompt or lower max_tokens to force) - Real integration with /vectors/hybrid endpoint (test does in-memory cosine instead, bypassing gateway vector surface) - Observer consumption of these runs (nothing posted to :3800 during the test — adding that is Phase A integration, handled separately) Files: tests/real-world/enrich_prd_pipeline.ts (333 LOC) tests/real-world/runs/moamj810/{iter_1..6.json, summary.json} — artifacts from the stress run, committed for inspection Follow-ups worth doing: 1. Lower max_tokens / harder prompt to force continuation path 2. Route retrieval through /vectors/hybrid for real Phase 19 boost 3. POST per-iteration summary to observer :3800 so runs accumulate like scenario runs do Co-Authored-By: Claude Opus 4.7 (1M context) --- tests/real-world/enrich_prd_pipeline.ts | 431 ++++++++++++++++++++++++ 1 file changed, 431 insertions(+) create mode 100644 tests/real-world/enrich_prd_pipeline.ts diff --git a/tests/real-world/enrich_prd_pipeline.ts b/tests/real-world/enrich_prd_pipeline.ts new file mode 100644 index 0000000..d0f6f56 --- /dev/null +++ b/tests/real-world/enrich_prd_pipeline.ts @@ -0,0 +1,431 @@ +// Real-world architecture stress test — 6 iterations of the full pipeline +// against the PRD as a corpus.

Per-cloud-call continuation (Phase 21 primitive) — when a single cloud call returns empty or truncated, stitches up to 6 continuation calls. Handles output-overflow. 2. Per-TASK retry (this commit) — when the whole task errors (500/404, thin answer, etc.), retries the full task up to 6 times. Each retry gets PRIOR ATTEMPTS' failures injected into the prompt as learning context, so attempt N+1 is informed by what N failed at. Handles error-recovery with compounding context. Both loops fired on iter 3 of the stress run, proving them independent and composable: FORCING TASK-RETRY LOOP — iter 3 will cycle through 5 invalid models + 1 valid attempt 1/6: model=deliberately-invalid-model-attempt-1 /v1/chat 502: ollama.com 404: model not found attempt 2/6: [with prior-failure context] ...

The task: generate a Rust async function with 15 specific structural rules (exact signature, bounded concurrency, exponential backoff 250/500/1000ms, NO .unwrap(), rustdoc comments, etc.). Small enough to fit in one response but strict enough that one rule violation = not accepted. Fits Rust + async + concurrency + error-handling — across the hardest dimensions for 7B models. Escalation ladder (corrected per J — kimi-k2.x requires Ollama Cloud Pro subscription which J's key lacks; mistral-large-3:675b is the biggest provisioned model): 1. qwen3.5:latest (local 7B) 2. qwen3:latest (local 7B) 3. gpt-oss:20b (local 20B) 4. gpt-oss:120b (cloud 120B) 5. devstral-2:123b (cloud 123B coding specialist) 6. mistral-large-3:675b (cloud 675B — biggest available) Each attempt gets PRIOR failures' rubric violations injected as learning context. Loop caps at MAX_ATTEMPTS=6. Live run (runs/hard_task_moapd3g3/): attempt 1: qwen3.5:latest 11/15 — missed concurrency + some constraints attempt 2: qwen3:latest 11/15 — different misses after learning attempt 3: gpt-oss:20b 0/1 — empty response (local model dead-end) attempt 4: gpt-oss:120b 0/1 — empty (heavy learning context may confuse) attempt 5: devstral-2:123b 15/15 ✅ ACCEPTED after 10.4s attempt 6: (not reached) Total: 5 attempts, 145.6s, coding-specialist succeeded. Honest findings from the run: - Pipeline works: escalated through 4 distinct model tiers, injected learning, bounded at 6, graceful failure surfaces. - Learning injection doesn't always help general-purpose models — gpt-oss:120b returned empty when given heavy prior-failure context (attempt 4). The coding specialist (devstral) worked better because the task is domain-aligned. - Local 7B came within 4 rules of success first-try (11/15) — not bad for the scale, but specific constraints like "EXACT signature" and "bounded concurrency at 4" are where small models slip. - Kimi K2.5/K2.6 both require a paid subscription on our current Ollama Cloud key — verified via direct ollama.com curl. Swap to kimi once subscription lands. Also includes a rubric bug-fix caught in the run: the regex for "reaches 500/1000ms backoff" originally required literal constants, but devstral-2:123b wrote idiomatic `retry_delay *= 2;` which doubles 250 → 500 → 1000 correctly. Broadened rubric to recognize `*= 2`, bit-shift, `.pow()`, and literal forms. Without this the ladder would have false-failed on semantically-correct code.

Local 7B handled review-style tasks first-try. The escalation ladder infrastructure is live but didn't fire — review is an easier task shape than strict code-generation (see hard_task test which needed devstral-2 specialist). 2. 6KB file-truncation caused one false positive: model claimed playbook_memory.rs lacks a `doc_refs` field, but that field exists past the 6KB cutoff. Trade-off between context-size and review-depth needs tuning per file. 3. Chunk-offset citations are real: model output includes `[PRD @27880]` and `[PLAN @16320]` which map to the actual byte offsets of retrieved context chunks. Auditor pattern could adopt this for traceable claims. This is the scrum-master-handoff shape J asked for: repo + PRD + proposal → chunk → retrieve → escalate → consolidate → human-reviewable markdown report Not shipping: per-PR diff analysis, open-PR integration, Gitea posting of suggestions. Those compose the same primitives differently — this proves the core pattern. Env override: LH_SCRUM_FILES=path1,path2,... to target a different file set. Default 3 files keeps runtime ~2min.

Previously, the review prompt truncated the file to first-chunk, which caused false-positive "field is missing" findings whenever the actual field was past the cutoff. Now each file >FILE_TREE_SPLIT_THRESHOLD (6000) is sharded at FILE_SHARD_SIZE (3500), each shard summarized via gpt-oss:120b cloud, and the distillations merged into a scratchpad. The review then runs against the scratchpad with an explicit truncation-awareness clause in the prompt: "DO NOT claim any field, function, or feature is 'missing' based on its absence from this distillation." Also writes each accepted review as a JSONL row to data/_kb/scrum_reviews.jsonl (file, reviewed_at, accepted_model, accepted_on_attempt, attempts_made, tree_split_fired, preview). This is the source the auditor's kb_query reads to surface per-file scrum reviews on PRs that touch those files (cohesion plan Phase C).

Also adds auditor/audit_one.ts — a dry-run CLI for auditing a single PR without posting to Gitea, useful for verifying check behavior without spamming review comments. Verified: after writing scrum_reviews for auditor/audit.ts and mcp-server/observer.ts (both in PR #7), audit_one 7 surfaced both as info findings with preview + accepted_model + tree_split flag.

The systemd auditor blocked PR #8 on 'unimplemented!()' / 'todo!()' in tests/real-world/hard_task_escalation.ts — but those strings are the rubric itself, not macro calls. Added isInsideQuotedString() detection in static.ts: BLOCK_PATTERNS now skip matches that fall inside double-quoted / single-quoted / backtick string literals on the added line. WARN/INFO patterns still run — a TODO comment in a string is still a valid signal. 2. Verdicts were being persisted to disk but never fed back as learning signal. Added appendAuditLessons() — every block/warn finding writes a JSONL row to data/_kb/audit_lessons.jsonl with a path-agnostic signature (strips file paths, line numbers, commit hashes) so the SAME class of finding on DIFFERENT files dedups to one signature. kb_query now tails audit_lessons.jsonl and emits recurrence findings: 2 distinct PRs hit a signature = info, 3-4 = warn, 5+ = block. Severity ramps on distinct-PR count, not total rows, so a single unfixed PR being re-audited doesn't inflate its own recurrence score. Fires on post-verdict fire-and-forget (can't break the audit if disk write fails). The learning loop is now closed: each audit contributes to the KB that guides the next audit. Tested: unit tests for normalizedSignature confirmed path-agnostic dedup; static.ts regression tests confirmed rubric strings no longer trip BLOCK while real unquoted unimplemented!() still does. --- auditor/audit.ts | 52 +++++++++++++++++++++++++++- auditor/checks/kb_query.ts | 71 ++++++++++++++++++++++++++++++++++++++ auditor/checks/static.ts | 27 ++++++++++++++- 3 files changed, 148 insertions(+), 2 deletions(-) diff --git a/auditor/audit.ts b/auditor/audit.ts index ae5fdc8..8fb0aee 100644 --- a/auditor/audit.ts +++ b/auditor/audit.ts @@ -12,7 +12,8 @@ // review — reviews have self-review restrictions on Gitea and the // auditor currently uses the same PAT as the PR author). -import { readFile, writeFile, mkdir } from "node:fs/promises"; +import { readFile, writeFile, mkdir, appendFile } from "node:fs/promises"; +import { createHash } from "node:crypto"; import { join } from "node:path"; import type { PrSnapshot, Verdict, Finding } from "./types.ts"; import { getPrDiff, postCommitStatus, postIssueComment } from "./gitea.ts"; @@ -24,6 +25,10 @@ import { runInferenceCheck } from "./checks/inference.ts"; import { runKbCheck } from "./checks/kb_query.ts"; const VERDICTS_DIR = "/home/profit/lakehouse/data/_auditor/verdicts"; +// Playbook for audit findings — one row per block/warn finding from a +// verdict. kb_query tails this next audit and escalates recurrences. +// Structured as JSONL so it's cheap to append and cheap to tail. +const AUDIT_LESSONS_JSONL = "/home/profit/lakehouse/data/_kb/audit_lessons.jsonl"; export interface AuditOptions { // Skip the cloud inference call (fast path for iteration).

Investigation showed two distinct bug classes that weren't "ship bad code", they were "auditor misreads the diff": 1. Cloud flagged "X not defined in this diff / missing implementation" for symbols like `tailJsonl` and `stubFinding` that ARE defined — just not in the added lines of this diff. Fix: extract candidate symbols from the cloud's gap summary, grep the repo for their definitions (function/const/let/def/class/struct/enum/trait/fn). If every named symbol resolves, drop the finding; if some do, demote to info with the resolution in evidence. 2. Cloud flagged runtime metrics like "58 cloud calls, 306s end-to-end" as unbacked claims. These are empirical outputs from running the test, not things a static diff can prove. Fix: claim_parser now has an `empirical` strength class matching iteration counts, cloud-call counts, duration metrics, attempt counts, tier-count phrases. Inference drops empirical claims from its cloud prompt (verifiable[] subset only) and claim-index mapping uses verifiable[] so cloud responses still line up. Added `claims_empirical` to audit metrics so the verdict is introspectable: how many claims WERE runtime-only vs how many are diff-verifiable? Verified: unit tests confirm empirical classification on 5 sample commit messages; symbol resolver found both false-positive symbols (tailJsonl + stubFinding) and correctly skipped a known- fake symbol. --- auditor/audit.ts | 1 + auditor/checks/inference.ts | 120 ++++++++++++++++++++++++++++++++++-- auditor/claim_parser.ts | 36 ++++++++++- auditor/types.ts | 9 ++- 4 files changed, 159 insertions(+), 7 deletions(-) diff --git a/auditor/audit.ts b/auditor/audit.ts index 8fb0aee..18bf732 100644 --- a/auditor/audit.ts +++ b/auditor/audit.ts @@ -77,6 +77,7 @@ export async function auditPr(pr: PrSnapshot, opts: AuditOptions = {}): Promise< claims_strong: claims.filter(c => c.strength === "strong").length, claims_moderate: claims.filter(c => c.strength === "moderate").length, claims_weak: claims.filter(c => c.strength === "weak").length, + claims_empirical: claims.filter(c => c.strength === "empirical").length, claims_total: claims.length, diff_bytes: diff.length, }; diff --git a/auditor/checks/inference.ts b/auditor/checks/inference.ts index 6c121ec..d24bad2 100644 --- a/auditor/checks/inference.ts +++ b/auditor/checks/inference.ts @@ -13,6 +13,8 @@ // with a 15KB diff + claim list). import type { Claim, Finding } from "../types.ts"; +import { Glob } from "bun"; +import { readFile } from "node:fs/promises"; const GATEWAY = process.env.LH_GATEWAY_URL ??

Kills the "same unfixed PR inflates its own recurrence score" failure mode by design: confidence = distinct_scopes/count, so same-scope noise stays below the 0.3 escalation threshold no matter how many times it repeats. checkAuditLessons now routes through aggregate + ratingSeverity. Net effect: the recurrence detector's bespoke Map/Set bookkeeping is gone; same behavior, shared discipline, reusable by scrum/observer. Also: symbolsExistInRepo now skips files >500KB so the audit can't get stuck slurping a fixture. Phase 2 — nine-consecutive audit runner. tests/real-world/nine_consecutive_audits.ts pushes 9 empty commits, waits for each verdict, captures the audit_lessons aggregate state after each run, reports: - sig_count trajectory (should stabilize, not grow linearly) - max_count trajectory (same-signature repeat rate) - max_confidence trajectory (must stay LOW on same-PR noise) - verdict_stable across runs (must NOT oscillate) This is the empirical proof that the KB compounds favorably: noise doesn't escalate itself, and signal stays distinguishable. Unit-tested both failure modes: same-PR × 9 repeats = conf=0.11 (info); cross-PR × 5 distinct = conf=1.00 (block).
