From 61b13586e1ad4d6174bd3bfbd24c3a846854881c Mon Sep 17 00:00:00 2001 From: plind-junior <59729252+plind-junior@users.noreply.github.com> Date: Sat, 25 Jul 2026 03:10:28 +0900 Subject: [PATCH 1/9] feat(capture): extract answer claims once per session, not per turn MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit per-turn stop-hook extraction saw one answer at a time, which produced episodic fragments like "test coverage and green gates are noted at the end" — grammatical enough to pass admission, useless out of context, and filed with a fresh claim budget every turn. capture.answer_mode (default "session") moves answer memory to SessionEnd: finalize hands the whole transcript to capture_session_answers, which ingests every turn's final answer as one content-addressed document (questions stay in metadata so claims can only quote assistant prose), extracts receipt-backed claims with the full session in view, and spends one claim budget per session. identical spans collapse across turns and re-finalizing an unchanged transcript is a no-op. the stop hook stays wired: capture_answer now defers in session mode ("deferred-to-session-end"), and capture.answer_mode: turn restores the legacy per-turn behaviour unchanged. --- CHANGELOG.md | 10 ++ src/vouch/capture.py | 215 ++++++++++++++++++++++++++++++++--- src/vouch/cli.py | 10 +- src/vouch/storage.py | 3 + tests/test_adopt.py | 1 + tests/test_capture.py | 12 ++ tests/test_capture_answer.py | 203 ++++++++++++++++++++++++++++++--- tests/test_capture_scope.py | 5 +- 8 files changed, 427 insertions(+), 32 deletions(-) diff --git a/CHANGELOG.md b/CHANGELOG.md index 8a01124b..6ce3ec3f 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -7,6 +7,16 @@ All notable changes to vouch are documented here.

charset=UTF-8 Content-Transfer-Encoding: 8bit port the strongest idea in ditto's dream pipeline — small-model subject extraction as strict json — into the capture path, adapted to vouch's shape: one llm pass over the whole session record (intent + tool activity + changed files + git stat) instead of per exchange, output decorating the pending mechanical rollup page (title, summary and subjects sections, slugified subject tags, metadata) rather than writing anything durable. subjects become fts-indexed page tags, so a session is findable by subject even when the raw observation text never used those words together. the model is deployment config (capture.enrich.llm_cmd, falling back to compile.llm_cmd); the base install behaves exactly as before. failure never blocks: any llm or parse error files the plain page. the split-failure fallback path skips enrichment so a broken llm_cmd is not called twice in one run. finalize now runs session answers before the summary so the rollup page cites the session-answers source; a cited session page clears the admission gate's uncited-diary rule via the existing citation rule instead of a new exemption. already-captured answers return their source id so a re-finalize still cites it. --- src/vouch/capture.py | 45 +++++- src/vouch/enrich.py | 293 +++++++++++++++++++++++++++++++++++ src/vouch/session_split.py | 36 ++++- tests/test_capture_answer.py | 26 ++++ tests/test_enrich.py | 185 ++++++++++++++++++++++ tests/test_session_split.py | 86 ++++++++++ 6 files changed, 658 insertions(+), 13 deletions(-) create mode 100644 src/vouch/enrich.py create mode 100644 tests/test_enrich.py diff --git a/src/vouch/capture.py b/src/vouch/capture.py index a13dfcdb..f6b652ec 100644 --- a/src/vouch/capture.py +++ b/src/vouch/capture.py @@ -31,6 +31,7 @@ import yaml +from .enrich import Enrichment from .models import ProposalStatus from .secrets import mask_secrets from .storage import KBStore @@ -465,6 +466,7 @@ def build_summary_body( project: str | None = None, generated_at: str | None = None, first_prompt: str | None = None, + enrichment: Enrichment | None = None, ) -> tuple[str, str]: tool_counts: dict[str, int] = {} files: set[str] = set(changed_files) @@ -478,10 +480,13 @@ def build_summary_body( if cmd: commands.append(str(cmd)) # The title is what a reviewer scans in the queue: lead with the human's - # own words when the transcript offers them, else with what changed. + # own words when the transcript offers them, then the enrichment summary + # (what the session accomplished), else with what changed. # The session uuid stays in the body for traceability. if first_prompt: title = f"session: {_excerpt(first_prompt)}" + elif enrichment is not None and enrichment.summary: + title = f"session: {_excerpt(enrichment.summary)}" else: title = _fallback_title(files, len(observations), generated_at) if project: @@ -492,6 +497,14 @@ def build_summary_body( lines += [f"- session: `{session_id}`", f"- observations: {len(observations)}", ""] if first_prompt: lines += ["## prompt", "", f"> {first_prompt}", ""] + if enrichment is not None and enrichment.summary: + lines += ["## summary", "", enrichment.summary, ""] + if enrichment is not None and enrichment.subjects: + lines += ["## subjects", ""] + for s in enrichment.subjects: + desc = f": {s.description}" if s.description else "" + lines.append(f"- **{s.name}** ({s.type}){desc}") + lines.append("") if files: lines += ["## files modified this session", ""] lines += [f"- {f}" for f in sorted(files)[:20]] @@ -548,17 +561,29 @@ def finalize( intent = ( first_user_prompt(transcript_path) if transcript_path is not None else None ) - result = session_split.summarize( - store, session_id, intent=intent, cwd=cwd, project=project, - generated_at=generated_at, mode=mode, config=cfg, origin=origin, - ) + # Answers run FIRST so the summary page can cite the session source: an + # uncited session page is a diary the admission gate auto-rejects, while + # one citing the receipts-bearing source is reviewable knowledge.

Anyone can reproduce any score on any +machine; that reproducibility is the whole trust model. + +## How a season runs + +1. **Open.** A season issue announces: the pinned bench contract, the public + practice seeds, the bounty pool and split, and `main`'s current + per-category scores (the zeros are the levers — that table is the map of + where the money is). +2. **Enter.** An entry is a pull request labeled `season-N`. Every push gets + practice scores from CI automatically (the `vouchbench-season` workflow's + pull_request path — public seeds, instant feedback). +3. **Freeze.** At the announced cutoff timestamp, the last commit on each + entry is that entry. Pushing after the cutoff voids the entry for the + season (next season it can re-enter). +4. **Score.** A maintainer dispatches the scored run. The scored seeds are + derived from the public drand randomness round at the cutoff time and + recorded in the season issue — they did not exist while entries could + still change, so nothing can be pre-fit to them (commit-reveal). Every + entry and `main` run the same seeds; results are paired. +5. **Review.** Ranked entries get normal code review before any payout. + Grounds for disqualification: benchmark-keyed logic (lookup tables, + category-pattern dispatch, generator-template matching), bypassing the + review gate, or violating the repo's non-negotiables (no write path + around `proposals.approve()`, plaintext storage, no baked model deps). + Near-identical entries: the earlier-opened PR wins (first-seen). +6. **Pay and merge.** Every entry that beats `main`'s composite by the + margin band — `max(0.007, 1.64 x SE_paired)` over the scored seeds — + earns its rank share of the pool (65 / 14 / 10 / 7 / 4 while the field + is small). The winner merges and becomes the champion the next season + must dethrone. + +## Two ladders + +* **Ladder A — the score race** above. +* **Ladder B — flat bounties**: issues labeled `bounty:$X` for benchmark + hardening (new categories, better generators, anti-overfit work), + adapters, and bug fixes. Paid on merge after review. Ladder B is how the + benchmark itself keeps improving. + +## Payment + +Payouts go through a PR-native bounty platform (Polar.sh / Algora) or a +GitHub Sponsors one-time payment, at the maintainer's choice, within a week +of the season closing. The maintainer's decision on scores, bands, and +disqualifications is final; every input needed to re-derive a score +(seeds, commit, command) is public in the season issue. + +## Local loop for contributors + +```bash +pip install -e '.[dev]' +vouch bench run --seeds 1,2,3,4,5,6 # the public practice baseline +vouch bench gen --seed 1 # inspect a dataset + answer key +vouch bench run --seed 1 --json # full report with failures +``` + +The reference baseline and the current lever table live in +`src/vouch/bench.py`'s module docstring.
