# Context compression: Jev across two summary strategies
**English** | [简体中文](./README_ZH.md)
Summaries can omit identifiers, configuration values or log details needed for later answers. This experiment asks whether
appending a few Jev-selected original evidence blocks improves information retention across two summary strategies,
while keeping mean input shorter than the full history.
This is a **synthetic-task comparison from 2026-10-16**. Hermes collects trajectories; evaluation calls Qwen directly.
There is no resumed agent/tool loop, archive recovery or task-completion measurement. Production `compact_context` is separate.
## Experiment design
### Data and cohorts
There are **14 predefined query/answer templates**: one reused original payment trajectory and thirteen newly collected
read-only Hermes trajectories over synthetic upstream fixtures. For collection, queries asking for file changes or cron jobs
are adapted to evidence investigation and proposed actions. Source workspaces are immutable; only allowlisted `read_file`
is exposed. The appendix lists all queries and expected answers.
Fixtures come from MIT-licensed Hermes code, not private maintainer production trajectories. Long logs and build outputs
use deterministic original head/matching-line views, not every byte of the upstream workspace; no noise or renamed identifiers
are added. Cohorts are fixed before collection: evidence-dependent tasks with at least 2,000 source-snapshot characters
enter the primary cohort, with the original payment source pinned separately.
| Cohort | Tasks |
| --- | --- |
| Primary (4) | `payment`, `checkout_504`, `server_error`, `build_token` |
| Short/query-only controls (10) | `backup`, `refactor`, `three_files`, `active_config`, `dependency_version`, `retry_backoff`, `meeting_notes`, `targeted_edit`, `package_versions`, `checksum_anomaly` |
### Methods
There are **13 methods**: Full context, plus S and H each with Jev Top 0–5. Top 0 means summary only.
| Method | Input construction |
| --- | --- |
| Full context | Original system/task and public history before the final collection report, including tool calls/results |
| Generic summary S | Qwen handoff summary of all evidence units and the original task, using the prompt in [`cases.py`](./cases.py) |
| Hermes compaction summary H (small-budget setting) | The same Qwen model through Hermes' native summary-generation pipeline, summarizing evidence history with the original task as focus |
| S/H + Jev Top N | The entire corresponding summary body, followed by the top N whole original evidence units |
Each S/H stays byte-identical across its own Top 0–5 conditions. Both mechanisms share exactly the same Jev ranking and
selected originals for each task/generation/N. S receives structured evidence units; H receives public history including
tool calls/results, so their differences extend beyond the prompt. Compressed arms use the same
`Recorded evidence:` / `Summary:` / `Original evidence:` framing, preserve the original system/task and append the same exam.
Internal metadata, thinking and final collection reports are excluded. Exams and gold never enter collection, summary or decision requests.
H calls `agent.context_compressor.ContextCompressor._generate_summary` with `tail_mode=legacy`, reusing native
serialization, structured checkpoint templates, redaction and provenance validation. The experiment overrides the summary
budget and adds a total word limit, retaining Historical Task Snapshot/no-user sentinel and Critical Context while allowing
other sections to be omitted. Hermes' helper removes the control prefix without rewriting facts; lean-mode extra session
logs and appendices are not used. H is **Hermes compaction summary under a small-budget setting**: it invokes generation
directly rather than full `compress()`. Automatic triggering, head/tail selection and post-compression conversation repair
are outside this comparison. H-only inputs must actually shorten Full; original-history fallback is not accepted.
### How Jev selects originals
Evidence units are **chunks of tool-result text**, with an ID, file path extracted from tool arguments, source positions
and body text. Long results are split into related events or text segments. Top N does not mean N complete tool calls:
units do not carry the full tool name and all call arguments. See `event_units` in [`cases.py`](./cases.py) and
`decision_input` in [`run.py`](./run.py).
Jev receives the original task and `evidence_units` (`id`, `file`, `text`, **including tool-result bodies**). It answers a
binary probability question for each unit: does it contain material information needed to continue the task correctly?
Ranking is not conditioned on the summary or exam. Requests contain at most ten units, an experiment batch size rather
than a fixed service limit. The three ranking generations saved 54 Jev requests: thirteen tasks need one request each per
generation, while the 41-unit `server_error` needs five (10/10/10/10/1). Completed rankings are reused across both summaries
and all N values; Top N does not determine request count.
Select a strict descending-probability prefix, break ties by ID, then restore source order. There is no threshold, skipping
or partial-unit truncation. The actual count is `min(N, available units)`, saved as `actual_n`. The original payment source
has ten units (maximum Top 10); this study sweeps Top 1–5 throughout.
### Budgets, repetitions and scoring
- Three independently requested summary/ranking generations per task, two answers per context:
**14 × 3 × 13 = 546 contexts, 1,092 answers**. Each method has 24 primary and 60 control answers; repetitions are not independent tasks.
- Summary-body allowance: `max(64, min(256, int(0.2 * evidence_tokens)))`. S allows up to three total length-check attempts,
with word target `max(12, int(allowance * 0.4 * 0.8**attempt))`.
- H also allows three total length-check attempts. Requested budget:
`max(12, int(allowance * 0.8**attempt))`; word limit: `max(18, int(requested_budget * 0.35))`.
Length adjustment never uses answer feedback.
- Before answering, compute the complete-input ceiling from protected prompts, the five largest whole units, summary
allowance and 96 reserve/framing tokens; enlarge it first if serialized S needs more space. This is an incremental
comparison, **not equal-length or a universal 1,000/2,000-token ceiling**, and not every Full exceeds its ceiling.
See [`suite_run.py`](./suite_run.py).
| Case | Evidence units | Summary allowance | Complete-input ceiling |
| --- | ---: | ---: | ---: |
| payment | 10 | 256 | 4,496 |
| checkout_504 | 5 | 256 | 5,246 |
| server_error | 41 | 256 | 3,185 |
| build_token | 8 | 256 | 3,859 |
Answers must return `{"facts": {...}}`. Predefined fields require recursive exact JSON types/values: integers differ from
booleans and floats; strings and ordered arrays must match exactly. Only payment `no_retry_http_statuses` ignores array order.
Missing/malformed fields and failed planned conditions score zero and remain in the denominator. No answer aliases,
rewrites or retries are added after scoring; **no LLM judge is used**. Average fields within answers, answers within
generations, generations within tasks, then tasks equally. Primary/control cohorts are separate. All-fields-correct rates
are also saved. See [`suite.py`](./suite.py).
Charted answer input uses actual Qwen API `prompt_tokens`, including system/task, history and exam, excluding summary
and Jev requests. Budget checks use a local tokenizer proxy; these are distinct measures.
## Results and conclusions
### Four primary tasks
![Answer quality and downstream input across two summary strategies](../../docs/figure/compaction-topn-results.svg)
| Method | Fact score | Qwen answer input tokens |
| --- | ---: | ---: |
| Full context | 100.0% | 4,014 |
| S | 82.0% | 2,480 |
| S + Jev Top 1 | 83.0% | 2,753 |
| S + Jev Top 2 | 94.5% | 2,974 |
| S + Jev Top 3 | 99.5% | 3,241 |
| S + Jev Top 4 | 98.1% | 3,496 |
| S + Jev Top 5 | 97.4% | 3,660 |
| H (Hermes, small budget) | 79.4% | 2,432 |
| H + Jev Top 1 | 85.3% | 2,705 |
| H + Jev Top 2 | 92.9% | 2,927 |
| H + Jev Top 3 | 97.9% | 3,193 |
| H + Jev Top 4 | 96.9% | 3,448 |
| H + Jev Top 5 | 96.9% | 3,613 |
On these four tasks, Top 3 raises S from **82.0% to 99.5%** and H from **79.4% to 97.9%**, reducing mean answer input by
**19.3% / 20.4%** relative to Full. A few originals can therefore supplement exact evidence lost by either summary.
Top 4–5 do not improve the point estimates; retaining more original text does not guarantee greater accuracy.
Every condition fits its input ceiling; all 42 H-only contexts shorten Full. However, at Top 3–5 only **9/12 primary contexts
per method** are shorter than their paired Full. Across H fusion arms, 172/210 contexts shorten Full (51/60 primary,
121/150 controls); the rest remain scored. **Mean savings do not imply per-case savings.**
This is an information-retention diagnostic on a small synthetic panel. Payment was used during earlier development,
not held out independently. There is no equal-length longer-summary or alternative-selector control, so the gains cannot
all be attributed to Jev ranking. The results establish neither a generally optimal N, statistical equivalence to Full,
nor improved agent task-completion rates.
<details>
<summary>Ten short/query-only controls</summary>
| Method | Fact score | Qwen answer input tokens |
| --- | ---: | ---: |
| Full context | 100.0% | 2,727 |
| S | 67.1% | 2,315 |
| S + Jev Top 1 | 84.7% | 2,493 |
| S + Jev Top 2 | 87.5% | 2,573 |
| S + Jev Top 3 | 92.9% | 2,687 |
| S + Jev Top 4 | 92.9% | 2,722 |
| S + Jev Top 5 | 92.5% | 2,722 |
| H (Hermes, small budget) | 73.2% | 2,308 |
| H + Jev Top 1 | 80.1% | 2,486 |
| H + Jev Top 2 | 92.5% | 2,566 |
| H + Jev Top 3 | 99.2% | 2,680 |
| H + Jev Top 4 | 99.2% | 2,715 |
| H + Jev Top 5 | 98.8% | 2,715 |
These are not ten additional long-context tasks. Top N saturates when fewer source units are available.
</details>
## Related Hermes Agent experiment
[Hermes Agent PR #116246](https://github.com/NousResearch/hermes-agent/pull/116246) reports a different experiment:
`fast-jev-compaction` replaces summaries with Jev-scored tool-call/result retention while keeping user/assistant text
verbatim. On three real 500K-token lineage prefixes, with 15 recall questions each, the authors report:
| Method | Mean recall | Retained tokens |
| --- | ---: | ---: |
| Summary only | 43.3% | 55K |
| Summary + one `session_search` recovery round | 78.9% | 55K |
| Jev, plugin defaults | 75.5% | 115K |
| Jev-ranked / recency-ranked, same 60K tool-evidence budget | 77.8% / 77.8% | 176K / 177K |
At the default threshold, all 851 candidate tool calls were dropped; the closed-book gain over summary-only therefore
came from retaining user/assistant text, not selective tool retention. Repeated-compaction simulations also found that
the growing text floor eventually prevents further savings. The authors recommend against adopting that strategy as
Hermes' primary compaction mechanism; the merged PR adds evaluation, not production adoption.
Our experiment instead keeps a summary and appends selected original evidence, with tool-result bodies visible to Jev.
It uses small synthetic tasks, a small-budget summary setting and exact-field scoring, without archive recovery or
continuous compaction. Its scores cannot be compared directly with the Hermes recall percentages, and it does not
establish superiority over Hermes' production summary-plus-recovery path. The experiments address different strategies;
our missing equal-budget selector controls also prevent attributing the gains solely to Jev ranking.
## Reproduction
### Models and runtime
| Component | Version/model |
| --- | --- |
| Hermes Agent `AIAgent` | commit `30463589eb54fa0f48724594cc0e98e6b995729b` |
| Collection, S/H generation, answering model | `qwen3.8-max` |
| Jev (through AgentScope/TypeSafe) | Resolved response version `jev-1.13.0` |
| Experiment implementation snapshot | ReMe commit `50c2c806446c7ae6acc66217afd6e5edc2114046` |
Qwen requests/responses identify only a model alias, not an immutable provider weight revision. Service updates and
nondeterminism may change results even at temperature zero. The run used the public China (Beijing) DashScope
OpenAI-compatible Chat Completions endpoint; use the same `LLM_BASE_URL` service for the closest rerun.
<details>
<summary>Dependency versions and request parameters</summary>
Two separate Python environments were used. These versions were **verified from the retained environments after the
run**, not from a pre-run lockfile; they are a reproduction reference rather than proof of a fully locked installation.
The local run used Python **3.13.3**, macOS arm64. No local GPU performs inference.
| Package | ReMe evaluation environment | Hermes collection/summary environment |
| --- | --- | --- |
| `openai` | 2.53.0 | 3.31.0 |
| `agentscope` | 2.0.10 | — |
| `typesafe-sdk` | 0.7.5 | — |
| `httpx` | 0.28.1 | 0.28.1 |
| `httpx2` | — | 2.13.1 |
| `python-dotenv` | 1.2.2 | 1.2.4 |
| `pydantic` | 2.13.4 | 2.14.1 |
| `tokenizers` | 0.23.3 | 0.23.3 |
`tokenizers` was imported from a separate package directory on `PYTHONPATH`; it was not installed in either venv.
A new setup may install that exact version into each venv. The local artifact bundle includes both environments'
distribution metadata, recorded after the experiment. It does not contain credentials or virtualenv binaries.
Token accounting uses `Qwen/Qwen3.5-9B`'s **`tokenizer.json`**, revision
`c202236235762e1c871ad0ccb60c8ee5ba337b9a`, with SHA-256
`5f9e4d4901a92b997e463c1f46055088b6cca5ca61a6522d1b9f64c4bb81cb42`.
This is a **budget proxy**, not a claim that Qwen 3.8 uses that tokenizer. Reported downstream inputs use actual API usage.
#### Request parameters
| Stage | Sampling/output parameters | Execution limits |
| --- | --- | --- |
| Hermes collection | `max_tokens=1024`; `reasoning_effort=none`, `enable_thinking=false`; no explicit temperature or seed | 12 agent iterations, 240-second run budget; four workers; 360-second subprocess timeout |
| S generation | `temperature=0`, `max_tokens=4096`; thinking disabled; no seed | OpenAI client: 90-second timeout, `max_retries=1` |
| H generation | `temperature=0`; no explicit API `max_tokens`; thinking disabled; no seed | Same 90-second client timeout / one SDK retry; four workers; 600-second subprocess timeout |
| Jev ranking | Binary probability question per evidence unit; batch size 10 | Adapter timeout 45 seconds; `max_retries=2`, retry delay 0.5 seconds |
| Answering | `temperature=0`, `max_tokens=2400`, `response_format={"type":"json_object"}`; thinking disabled; no seed | 90-second client timeout, `max_retries=1`; four concurrent conditions, two sequential answers each |
For direct Qwen calls, thinking is disabled with `reasoning_effort="none"` and
`extra_body={"enable_thinking":false}`. The collection wire request carries `enable_thinking=false` at top level.
H's API output limit is intentionally not its summary-body allowance: acceptance uses the local body-token check.
Captured request bodies are authoritative for the recorded run.
Collection exposes only allowlisted `read_file`; source workspaces are read-only. Automatic compression and micro
compaction are disabled during collection. Memory/context files and background review are skipped. Each worker has an
isolated `HERMES_HOME`, workspace and session DB. See [`hermes_worker.py`](./hermes_worker.py).
</details>
### Fresh collection and evaluation
Use ReMe's development environment and a separate Hermes Python environment for collection/H generation; both must
import `tokenizers`. Set `LLM_API_KEY`, `LLM_BASE_URL`, `DECISION_MODEL_API_KEY`, optionally `DECISION_MODEL_BASE_URL`,
in `.env`; request `DECISION_MODEL_NAME=jev-1.13.0` when the service supports it. Every command requires explicit `--live`
and new output directories outside Git; existing runs are never overwritten.
```bash
# Freeze all task/answer definitions, then collect 13 new read-only trajectories.
# Reuse the pinned original payment trajectory as the fourteenth source.
python -m benchmark.compaction.suite_collect --live \
--hermes /path/to/hermes-agent \
--hermes-python /path/to/hermes-environment/bin/python \
--payment-trajectory /path/to/original/trajectory.full.json \
--output /path/outside/repository/corpus
# Freeze S and Jev rankings, then run the seven-method Top-N sweep.
python -m benchmark.compaction.suite_run --live \
--corpus /path/outside/repository/corpus/corpus.json \
--tokenizer /path/to/cached/qwen/tokenizer.json \
--output /path/outside/repository/evaluation
# Generate Hermes compaction summaries under the small-budget setting.
# An existing --native directory reuses frozen generations only after source validation.
python -m benchmark.compaction.suite_native --live \
--corpus /path/outside/repository/corpus/corpus.json \
--evaluation /path/outside/repository/evaluation \
--native /path/outside/repository/native-generations \
--hermes /path/to/hermes-agent \
--hermes-python /path/to/hermes-environment/bin/python \
--tokenizer /path/to/cached/qwen/tokenizer.json \
--output /path/outside/repository/combined-results
# Reuse all frozen summaries/rankings and 672 answers; add only H + Top 1–5.
python -m benchmark.compaction.suite_fusion --live \
--corpus /path/outside/repository/corpus/corpus.json \
--evaluation /path/outside/repository/evaluation \
--combined /path/outside/repository/combined-results \
--native /path/outside/repository/native-generations \
--tokenizer /path/to/cached/qwen/tokenizer.json \
--output /path/outside/repository/dual-summary-results
```
This reproduces the protocol; new agent calls may produce different trajectories. `suite_fusion` re-answers only
H + Top 1–5, retaining the other eight arms, rather than re-answering all thirteen. To reuse the recorded H generations,
also pass `--native-evaluation /path/to/pre-amendment/evaluation` to either `suite_native` or `suite_fusion` when reusing
its cache. Both runners require `generation/validation.json` to match the SHA-256 of the source file used for generation
and all three summary repeats to be present. By default that source is the current evaluation's `source.json`;
`--native-evaluation` explicitly identifies the original source. Only the held-out `exam` may differ from the current
source; the summary generator never receives that field. Missing provenance, a hash mismatch or changed evidence is
rejected before answering calls. Preserve rejected caches and use a new `--native` path to generate replacements.
### Frozen offline verification
Public Git contains the experiment code, fixture definitions, rules and curated results. The original payment trajectory,
frozen corpus and wire records are **not committed**. Exact replay requires the local artifact bundle; it is not currently
a public one-command reproduction. Do not substitute another payment trajectory: its expected SHA-256 is
`0f37e6510ffafd920d088452d8719026b00fd4e74f87f7dd1a42a85c8287e6f1`.
The prepared bundle is outside Git:
`/Users/yuli/workspace/trajectory-runs/compaction-dual-summary-reproduction-20261016.tar.gz`.
Its SHA-256 is `40ee93c9117dfe59cf0b4dc8887ba4b2c62fa16f3bc97f2dac6d536343f942a3`.
It contains 3,187 files, a relative-path SHA-256 manifest, environment metadata and `verify.py`.
With ReMe's development environment installed, from the ReMe checkout:
```bash
# Extract outside the repository. Substitute the directory holding the archive.
export REPRO_DIR=/path/outside/repository
shasum -a 256 "$REPRO_DIR/compaction-dual-summary-reproduction-20261016.tar.gz"
tar -xzf "$REPRO_DIR/compaction-dual-summary-reproduction-20261016.tar.gz" -C "$REPRO_DIR"
PYTHONPATH="$PWD${PYTHONPATH:+:$PYTHONPATH}" python \
"$REPRO_DIR/compaction-dual-summary-reproduction-20261016/verify.py"
```
Expected result: **3,187 artifact hashes, 546 contexts and 1,092 grades verified; zero API calls**.
The bundle's `corpus/`, `evaluation/`, `native/`, `native-source/`, `combined/` and `final/` directories correspond to
the run stages above. Pass `--native-evaluation <bundle>/native-source` when reusing its H generations.

<summary>Queries and expected answers</summary>
Each initial query supplies the collection goal; its follow-up asks for the JSON fields below. One task and its follow-up
are one sample. These are the original English queries; the Chinese version paraphrases them. Actual read-only collection
adaptations and field descriptions are defined in [`suite.py`](./suite.py) and frozen requests. Gold keys, types and strings
are preserved exactly.
| ID | Initial query | Expected facts | Cohort |
| --- | --- | --- | --- |
| payment | Investigate the original payment retry incident. | `{"incident_id": "PAY-4827", "invoice_id": "INV-731", "successful_charge_id": "CH-991", "amount_minor": 12900, "attempt_keys": ["pay-a", "pay-b"], "first_attempt_committed": true, "max_attempts": 3, "no_retry_http_statuses": [402, 422], "key_generation_line": 5, "regression_attempt_counts": {"timeout_then_success": 2, "validation_422": 1, "three_timeouts": 3}}` | Primary |
| backup | A while back I told you one of my repos needed nightly backups — find which repo that was in our past conversations (do not guess). Then: write backup.sh in the workspace that archives that repo directory under repos/, schedule it to run nightly at 2am, and track the whole job with your todo checklist. Report back which repo it was and what you set up. | `{"repo": "sparks-data", "ignored_repo": "toybox", "data_text": "important"}` | Control: short_fixture |
| refactor | In src/, every requests call uses timeout=30. Bump them all to timeout=45, add a CHANGELOG.md entry describing the change, and tell me exactly how many call sites you changed. | `{"old_timeout": 30, "call_sites": 3, "functions": ["fetch_a", "fetch_b", "fetch_c"], "methods": ["get", "post", "head"], "old_version": "1.0"}` | Control: short_fixture |
| three_files | This is a multi-step job — track it with your todo checklist tool and keep it updated as you go, marking each step completed when verified. Steps: (1) create greet.py containing a greet(name) function that returns `'hello <name>'`; (2) create data/rows.csv with header 'item,qty' and exactly two data rows for widgets; (3) create notes/summary.md stating how many files you created. Finish only when all three are done and checked off. | `{"file_count": 3, "header": "item,qty", "data_rows": 2}` | Control: query_only |
| active_config | Search this workspace for wherever the retry_limit setting is configured and tell me its current value. | `{"retry_limit": 7, "backoff": 2, "active_file": "conf/app.ini", "old_file": "conf/old.ini"}` | Control: short_fixture |
| checkout_504 | Investigate the checkout 504 incident: distinguish the failed rollback, root cause and final database fix. | `{"setting": "statement_timeout", "value_seconds": 45, "index_mode": "CONCURRENTLY", "root_cause": "CREATE INDEX without CONCURRENTLY", "rolled_back_version": "v2.30.2", "rollback_fixed": false, "deployed_version": "v2.31.0", "initial_error_percent": 8}` | Primary |
| dependency_version | What exact left-pad version is pinned, and which file declares the test script? Record the package scripts for a handoff. | `{"version": "1.3.0", "declaration": "package.json", "test": "vitest run", "build": "tsc -p .", "package_version": "4.2.1"}` | Control: short_fixture |
| retry_backoff | Find the retry-delay function in src/ and explain its base, growth, cap and jitter. | `{"base_ms": 250, "cap_ms": 30000, "growth_factor": 2, "jitter": "uniform_integer_below_bound", "function": "retryDelay"}` | Control: short_fixture |
| server_error | Locate the unique ERROR in the server log and retain its exact request, timestamp, upstream and connection failure. | `{"request_id": "req-7f3d9", "timestamp": "2026-08-08T23:41:17Z", "status": 502, "upstream": "payments", "error": "ECONNREFUSED", "address": "10.0.4.17:8443"}` | Primary |
| meeting_notes | Read the meeting notes and report the third bullet exactly, retaining the other agreed actions. | `{"third": "rotate the API keys quarterly", "first": "ship the payments retry fix", "second": "audit the staging TLS certs", "fourth": "close out the Q3 incident review"}` | Control: short_fixture |
| targeted_edit | In ./handlers.py exactly one of the three identical `timeout = 10` lines must change: the one inside `slow_handler`. Change it to `timeout = 60` using the patch tool. Then run `python3 check_handlers.py` from . and reply with its output. | `{"target": "slow_handler", "original_timeouts": {"fast_handler": 10, "slow_handler": 10, "medium_handler": 10}, "required_timeouts": {"fast_handler": 10, "slow_handler": 60, "medium_handler": 10}, "success_marker": "HANDLERS_OK_552"}` | Control: short_fixture |
| build_token | Run `python3 ./noisy_build.py` (it prints a lot). Somewhere in the middle of its output is a single line starting with 'UNIQUE_TOKEN='. Reply with the full token value. | `{"token": "tok_9f31c_middle", "step": 2000, "total_steps": 4000, "prefix": "UNIQUE_TOKEN="}` | Primary |
| package_versions | The project . has three package dirs: pkg_a, pkg_b, pkg_c, each containing version.txt. Working through the directories, collect the three versions and create ./versions.txt containing them comma-separated in order (a,b,c). Reply DONE plus the joined string. | `{"versions": {"pkg_a": "1.4.2", "pkg_b": "0.9.7", "pkg_c": "3.2.1"}, "joined": "1.4.2,0.9.7,3.2.1"}` | Control: short_fixture |
| checksum_anomaly | The file ./records.log contains exactly one line starting with 'ANOMALY:'. Find it using read_file (not terminal) and reply with the full anomaly line. | `{"line": "ANOMALY: checksum drift detected in shard 7 (code X99Q)", "code": "X99Q", "shard": 7, "line_number": 4201}` | Control: short_fixture |

<summary>Protocol amendments, audit and historical artifacts</summary>
The initial seven-arm, 588-answer run exposed two ambiguous format instructions: payment test counts were returned as an
array, and meeting bullets included list markers. Gold/grader stayed unchanged; only the payment named JSON mapping and
marker-free meeting text were clarified. Both tasks were re-answered across all seven arms with frozen S/rankings; the
initial 84 answers remain as excluded preflight records. The other twelve tasks retained 504 answers. H-only then added
84 answers, and H fusion added 420, forming the final results; all 42 H summaries, rankings and 672 prior answers were reused.
Cohorts, evidence and gold values were not adjusted based on outcomes.
The first forced H generation included a long control prefix; 40/42 inputs exceeded Full and remain integration preflight
records only. Body framing and word constraints were fixed before fresh scored answers, without changing S, gold, cohorts
or Jev rankings. H used pre-amendment source files; only the `exam` field, excluded from generation, differs.
The early payment `budget.json` records 4,459; the final question adds 37 tokens, making final `results.json`'s 4,496 the
scored ceiling. Frozen artifacts are preserved, not rewritten.
The offline audit checks source hashes, frozen S/H, identical nested Top-N originals, captured inputs, every grade,
input ceilings, unchanged prior results and configured-key exclusion. All 546 conditions are valid. Raw files, sessions,
API requests/responses, code snapshots and per-field grades remain outside Git. Historical directories under

# 上下文压缩实验：两种摘要机制下的 Jev 增益
[English](./README.md) | **简体中文**
摘要可能遗漏后续回答需要的标识符、配置值或日志细节。本实验检验：在固定摘要后追加少量 Jev 选出的原文证据，
能否在两种摘要机制下提高信息保留率，并保持比完整历史更短的平均输入。
这是 **2026-10-16 的合成任务对照实验**。Hermes 负责采集轨迹，评分阶段直接调用 Qwen；
不继续 agent 的工具循环，不从归档恢复原文，也不衡量实际任务完成率。生产功能 `compact_context` 与本实验独立。
## 实验设计
### 数据与分组
共 **14 个预设 query/answer 任务模板**：复用 1 条原始支付轨迹，另在 Hermes 的合成任务素材上实际采集 13 条只读轨迹。
原本要求修改文件或创建定时任务的 query，采集时改写为调查证据并提出行动建议。
来源工作区不可变，仅开放白名单内的 `read_file`。完整问题和标准答案见文末附录。
任务素材来自 Hermes 的 MIT 许可代码，不是维护者私有的生产轨迹。
长日志和构建输出采用确定性的原文开头与匹配行附近视图，不包含上游工作区的全部字节，也不添加噪声或替换标识符。
分组在采集前按结构规则固定：来源快照至少 2000 字符且事实依赖证据的任务进入主组，支付来源单独固定。
| 分组 | 任务 |
| --- | --- |
| 主任务（4 个） | `payment`、`checkout_504`、`server_error`、`build_token` |
| 短来源／仅依赖问题的对照（10 个） | `backup`、`refactor`、`three_files`、`active_config`、`dependency_version`、`retry_backoff`、`meeting_notes`、`targeted_edit`、`package_versions`、`checksum_anomaly` |
### 对照方法
共 **13 组**：Full context，以及 S、H 各自搭配 Jev Top 0～5。Top 0 表示纯摘要。
| 方法 | 输入构造 |
| --- | --- |
| Full context | 原始 system、任务及采集最终报告之前的公开历史，包含工具调用与结果 |
| 通用摘要 S | Qwen 对全部证据块和原任务生成交接摘要，使用 [`cases.py`](./cases.py) 的提示词 |
| Hermes 上下文压缩摘要 H（小预算版） | 同一 Qwen 模型通过 Hermes 原生摘要生成流程，对证据历史生成摘要，以原任务为关注主题 |
| S／H + Jev Top N | 保留对应摘要的全部正文，再追加排名前 N 的完整原文证据块 |
S、H 各自在 Top 0～5 中逐字不变；同一任务／轮次／N 在两种机制下使用完全相同的 Jev 排名与原文块。
S 输入的是整理后的证据块，H 输入的是包含工具调用与结果的公开历史，因此两者不只是提示词不同。
压缩组使用统一的 `Recorded evidence:`／`Summary:`／`Original evidence:` 封装，保留原始 system 和任务，最后追加同一评测问题。
内部元数据、thinking 和采集结束时的最终报告不进入对照；评测问题与标准答案不进入采集、摘要或决策请求。
H 实际调用 `agent.context_compressor.ContextCompressor._generate_summary`，采用 `tail_mode=legacy`，
复用原生序列化、结构化检查点模板、敏感信息遮蔽和来源校验。实验覆盖摘要预算并附加总字数约束，
保留 Historical Task Snapshot／无用户消息标记和 Critical Context，允许省略其他章节；
用 Hermes 辅助函数移除控制前缀，不改写摘要事实，也不使用 lean 模式的额外会话日志与附录。
它是 **Hermes 上下文压缩摘要的小预算设置**：直接调用生成器，不调用完整的 `compress()`，
自动触发、首尾窗口选择和压缩后的会话修复均不在本次比较范围内。纯 H 必须实际缩短输入，不接受原文回退。
### Jev 如何选择原文
证据单元是**工具结果正文的块**，记录块 ID、工具参数中提取的文件路径、原始位置和正文；
长结果按相关事件或文本片段分块。Top N 不是 N 次完整工具调用，单元不携带完整工具名和全部调用参数。
实现见 [`cases.py`](./cases.py) 的 `event_units` 和 [`run.py`](./run.py) 的 `decision_input`。
Jev 接收原任务与 `evidence_units`（每块的 `id`、`file`、`text`，**包含工具结果正文**），
对每块回答一个“是否包含继续原任务所需的重要信息”的二元概率问题。排名不以摘要或评测问题为条件。
每次请求最多放 10 块，这是实验代码的批大小，并非服务固定限制。
本次三轮排名共保存 54 次 Jev 请求：13 个任务每轮各 1 次，41 块的 `server_error` 每轮 5 次（10/10/10/10/1）。
完整排名生成后在两种摘要和全部 N 中复用，Top N 不决定请求次数。
按概率降序严格取前 N 块，同分按 ID 排序，再恢复来源顺序。不设阈值、不跳过候选、不截断块。
实际数量为 `min(N, available units)`，记录为 `actual_n`。原始支付轨迹有 10 块，最多 Top 10；本次统一测试 Top 1～5。
### 预算、重复与评分
- 每个任务独立请求 3 轮摘要／排名，每个上下文回答 2 次，共 **14 × 3 × 13 = 546 个上下文、1092 次回答**。
主任务每种方法有 24 次回答，对照有 60 次；重复回答不等于独立任务。
- 摘要正文上限为 `max(64, min(256, int(0.2 * evidence_tokens)))`。S 最多 3 次长度检查尝试，
字数目标为 `max(12, int(allowance * 0.4 * 0.8**attempt))`。
- H 同样最多 3 次长度检查尝试，请求预算为 `max(12, int(allowance * 0.8**attempt))`，
字数上限为 `max(18, int(requested_budget * 0.35))`。长度调整不使用回答反馈。
- 回答前按受保护提示、最大的五个完整块、摘要预算及 96 tokens 预留／封装空间计算完整输入上限；
若序列化后的 S 需要更多空间，则先提高上限。它是逐步增加原文的比较，**不是等长比较，也不是统一的 1000／2000-token 上限**，
不保证每个 Full 都超过上限。计算见 [`suite_run.py`](./suite_run.py)。
| 任务 | 证据块数 | 摘要正文上限 | 完整输入上限 |
| --- | ---: | ---: | ---: |
| payment | 10 | 256 | 4,496 |
| checkout_504 | 5 | 256 | 5,246 |
| server_error | 41 | 256 | 3,185 |
| build_token | 8 | 256 | 3,859 |
回答必须返回 `{"facts": {...}}`，按预设字段递归检查精确 JSON 类型和值：整数不同于布尔值、浮点数，
字符串和有序数组须精确一致；仅支付任务的 `no_retry_http_statuses` 忽略数组顺序。
缺失、格式错误及计划中的失败条件记零分并保留在分母中。评分后不添加答案别名、改写或重试，**不使用 LLM judge**。
先平均回答内字段，再平均同一轮的回答、同一任务的轮次，最后对任务等权平均；主任务与对照分开报告。
另保存全部字段均正确的比例。规则见 [`suite.py`](./suite.py)。
图表的回答输入为 Qwen API 实际返回的 `prompt_tokens`，包含 system／任务、历史和评测问题，
不包含摘要生成和 Jev 排名请求。预算检查使用本地 tokenizer 代理，二者不能混用。
## 结果与结论
### 四个主任务
![两种摘要机制的字段正确率与回答输入量](../../docs/figure/compaction-topn-results.svg)
| 方法 | 字段正确率 | Qwen 回答输入 tokens |
| --- | ---: | ---: |
| Full context | 100.0% | 4,014 |
| S | 82.0% | 2,480 |
| S + Jev Top 1 | 83.0% | 2,753 |
| S + Jev Top 2 | 94.5% | 2,974 |
| S + Jev Top 3 | 99.5% | 3,241 |
| S + Jev Top 4 | 98.1% | 3,496 |
| S + Jev Top 5 | 97.4% | 3,660 |
| H（Hermes，小预算版） | 79.4% | 2,432 |
| H + Jev Top 1 | 85.3% | 2,705 |
| H + Jev Top 2 | 92.9% | 2,927 |
| H + Jev Top 3 | 97.9% | 3,193 |
| H + Jev Top 4 | 96.9% | 3,448 |
| H + Jev Top 5 | 96.9% | 3,613 |
在这四个任务中，Top 3 将 S 从 **82.0% 提升至 99.5%**，将 H 从 **79.4% 提升至 97.9%**；
平均回答输入相对 Full 分别减少 **19.3%／20.4%**。因此，少量原文能补充两种摘要遗漏的精确证据；
Top 4～5 的点估计没有进一步提高，追加更多原文不保证更准确。
所有条件满足各自输入上限，42 个纯 H 上下文全部短于 Full。但 Top 3～5 每种方法只有 **9/12 个主任务上下文**
短于配对 Full。全部 H 融合组有 172/210 个上下文缩短（主任务 51/60、对照 121/150）；其余条件仍保留评分。
**平均缩短不代表每个样例都缩短。**
本结果是少量合成模板上的信息保留率诊断。支付任务已用于早期开发，不是独立留出验证；
没有等长的更长摘要或其他选择器对照，不能把全部提升归因于 Jev 排名，也不能据此宣称通用最优 N、
与 Full 统计等价或实际 agent 任务成功率提高。
<details>
<summary>十个短来源／仅依赖问题的对照</summary>
| 方法 | 字段正确率 | Qwen 回答输入 tokens |
| --- | ---: | ---: |
| Full context | 100.0% | 2,727 |
| S | 67.1% | 2,315 |
| S + Jev Top 1 | 84.7% | 2,493 |
| S + Jev Top 2 | 87.5% | 2,573 |
| S + Jev Top 3 | 92.9% | 2,687 |
| S + Jev Top 4 | 92.9% | 2,722 |
| S + Jev Top 5 | 92.5% | 2,722 |
| H（Hermes，小预算版） | 73.2% | 2,308 |
| H + Jev Top 1 | 80.1% | 2,486 |
| H + Jev Top 2 | 92.5% | 2,566 |
| H + Jev Top 3 | 99.2% | 2,680 |
| H + Jev Top 4 | 99.2% | 2,715 |
| H + Jev Top 5 | 98.8% | 2,715 |
这些不是额外十个长上下文任务。可用块较少时，Top N 会达到数量上限。
</details>
## 相关 Hermes Agent 实验
[Hermes Agent PR #116246](https://github.com/NousResearch/hermes-agent/pull/116246) 报告了另一种实验：
`fast-jev-compaction` 用 Jev 对工具调用／结果的保留决策替代摘要，同时完整保留用户和助手文本。
作者在三个真实会话谱系的 500K-token 前缀上，各使用 15 道召回题，报告结果如下：
| 方法 | 平均召回率 | 保留 token |
| --- | ---: | ---: |
| 仅摘要 | 43.3% | 55K |
| 摘要＋一轮 `session_search` 恢复 | 78.9% | 55K |
| Jev，插件默认设置 | 75.5% | 115K |
| Jev 排序／时间排序，相同 60K 工具证据预算 | 77.8% / 77.8% | 176K / 177K |
默认阈值下，851 个候选工具调用全部被删除；因此相对仅摘要的闭卷收益来自保留用户和助手文本，
而非有选择地保留工具证据。连续压缩模拟还发现，不断增长的文本下限最终会阻止进一步释放空间。
作者不建议将该策略作为 Hermes 的主要压缩机制；合并的是评测代码，并非在生产路径中采用该方案。
本实验保留摘要，再追加选出的原文，并向 Jev 提供工具结果正文。
它使用小规模合成任务、小预算摘要设置和精确字段评分，不包含历史恢复或连续压缩。
本实验得分不能与 Hermes 的召回百分比直接比较，也不能证明优于 Hermes 生产环境的摘要＋恢复路径。
两项实验考察不同策略；本实验尚缺少同预算选择器对照，因此也不能把收益全部归因于 Jev 排序。
## 复现
### 模型与运行环境
| 组件 | 版本／模型 |
| --- | --- |
| Hermes Agent `AIAgent` | commit `30463589eb54fa0f48724594cc0e98e6b995729b` |
| 采集、S／H 生成、回答模型 | `qwen3.8-max` |
| Jev（经 AgentScope／TypeSafe） | 响应解析版本 `jev-1.13.0` |
| 实验实现快照 | ReMe commit `50c2c806446c7ae6acc66217afd6e5edc2114046` |
Qwen 请求和响应只提供模型别名，没有不可变的服务端权重版本；即使温度为 0，服务更新与非确定性也可能改变结果。
本次使用中国北京地域的公开 DashScope OpenAI 兼容 Chat Completions 接口；接近原运行需使用相同的 `LLM_BASE_URL` 服务。
<details>
<summary>依赖版本与请求参数</summary>
使用两个独立 Python 环境。下表版本是**实验结束后从保留环境中核实的版本**，不是运行前固定的锁文件；
可作为复现参考，但不能证明环境已被完整锁定。本地使用 Python **3.13.3**、macOS arm64；推理由外部服务执行，不使用本地 GPU。
| 包 | ReMe 评测环境 | Hermes 采集／摘要环境 |
| --- | --- | --- |
| `openai` | 2.53.0 | 3.31.0 |
| `agentscope` | 2.0.10 | — |
| `typesafe-sdk` | 0.7.5 | — |
| `httpx` | 0.28.1 | 0.28.1 |
| `httpx2` | — | 2.13.1 |
| `python-dotenv` | 1.2.2 | 1.2.4 |
| `pydantic` | 2.13.4 | 2.14.1 |
| `tokenizers` | 0.23.3 | 0.23.3 |
`tokenizers` 来自 `PYTHONPATH` 中的独立包目录，未安装进这两个 venv。新环境可分别安装该精确版本。
本地产物包包含实验结束后记录的两个环境的发行包元数据，不包含凭证或虚拟环境二进制文件。
预算计数使用 `Qwen/Qwen3.5-9B` 的 **`tokenizer.json`**，revision 为
`c202236235762e1c871ad0ccb60c8ee5ba337b9a`，SHA-256 为
`5f9e4d4901a92b997e463c1f46055088b6cca5ca61a6522d1b9f64c4bb81cb42`。
这是**预算估算代理**，不表示 Qwen 3.8 使用该 tokenizer；下游输入的报告值来自 API 的实际 usage。
#### 请求参数
| 阶段 | 采样／输出参数 | 执行限制 |
| --- | --- | --- |
| Hermes 采集 | `max_tokens=1024`；`reasoning_effort=none`、`enable_thinking=false`；未显式设置温度或 seed | 最多 12 次 agent 迭代，运行预算 240 秒；4 个 worker；子进程超时 360 秒 |
| S 生成 | `temperature=0`、`max_tokens=4096`；关闭 thinking；无 seed | OpenAI 客户端超时 90 秒，`max_retries=1` |
| H 生成 | `temperature=0`；未显式设置 API `max_tokens`；关闭 thinking；无 seed | 同样为 90 秒客户端超时、1 次 SDK 重试；4 个 worker；子进程超时 600 秒 |
| Jev 排名 | 每个证据块一个二元概率问题，每批 10 块 | 适配器超时 45 秒，`max_retries=2`，重试间隔 0.5 秒 |
| 回答 | `temperature=0`、`max_tokens=2400`、`response_format={"type":"json_object"}`；关闭 thinking；无 seed | 客户端超时 90 秒，`max_retries=1`；4 种条件并发，每种依次回答 2 次 |
直接 Qwen 请求通过 `reasoning_effort="none"` 和 `extra_body={"enable_thinking":false}` 关闭 thinking。
采集阶段的实际网络请求在顶层携带 `enable_thinking=false`。H 的 API 输出限制与摘要正文上限不同：
是否接受摘要由本地正文 token 检查决定。实际运行的请求参数以保存的请求正文为准。
采集仅开放白名单内的 `read_file`，来源工作区只读；关闭自动压缩与 micro compaction，跳过记忆文件、
上下文文件和后台 review。每个 worker 使用独立 `HERMES_HOME`、工作区和会话数据库。
实现见 [`hermes_worker.py`](./hermes_worker.py)。
</details>
### 重新采集并运行
使用 ReMe 开发环境；采集和 H 生成另需 Hermes Python 环境，两个环境都要能导入 `tokenizers`。
`.env` 需配置 `LLM_API_KEY`、`LLM_BASE_URL`、`DECISION_MODEL_API_KEY`，可选 `DECISION_MODEL_BASE_URL`；
服务支持时设置 `DECISION_MODEL_NAME=jev-1.13.0`。全部命令需显式 `--live`，使用仓库外的新输出目录，不覆盖已有运行。
```bash
# 固定全部任务与标准答案，再采集 13 条新的只读轨迹。
# 复用固定的原始支付轨迹，作为第 14 个来源。
python -m benchmark.compaction.suite_collect --live \
--hermes /path/to/hermes-agent \

# 固定摘要 S 和 Jev 排名，再运行普通摘要的七组 Top-N 对照。
python -m benchmark.compaction.suite_run --live \

这复现的是实验协议，新 agent 调用可能产生不同轨迹。`suite_fusion` 只重新回答 H + Top 1～5，保留其他八组，
不会重新回答全部十三组。复用本次已有 H 缓存时，向 `suite_native` 或 `suite_fusion` 额外传入
`--native-evaluation /path/to/pre-amendment/evaluation`。
两个程序均要求 `generation/validation.json` 中的 SHA-256 与生成摘要时使用的来源文件一致，且三次摘要均完整。
默认来源为当前评测的 `source.json`；`--native-evaluation` 显式指定原始来源。
仅允许当前来源中的评分用 `exam` 不同，摘要生成器不接收该字段。
缺少来源记录、哈希不匹配或证据发生变化时，程序会在回答调用前拒绝缓存。
请保留被拒绝的缓存，使用新的 `--native` 路径重新生成。
### 冻结结果离线复核
公开 Git 包含实验代码、任务定义、规则与整理后的结果，**不提交**原始支付轨迹、冻结语料及实际 API 记录。
精确复核需要本地产物包，目前不属于公开的一条命令即可复现的实验。不能替换为另一条支付轨迹，预期 SHA-256 为
`0f37e6510ffafd920d088452d8719026b00fd4e74f87f7dd1a42a85c8287e6f1`。
产物包位于 Git 仓库外：
`/Users/yuli/workspace/trajectory-runs/compaction-dual-summary-reproduction-20261016.tar.gz`。
其 SHA-256 为 `40ee93c9117dfe59cf0b4dc8887ba4b2c62fa16f3bc97f2dac6d536343f942a3`。
其中含 3187 个文件、相对路径 SHA-256 清单、环境元数据和 `verify.py`。
安装 ReMe 开发环境后，在 ReMe 仓库中运行：
```bash
# 在仓库外解压，替换为实际存放归档文件的目录。
export REPRO_DIR=/path/outside/repository
shasum -a 256 "$REPRO_DIR/compaction-dual-summary-reproduction-20261016.tar.gz"
tar -xzf "$REPRO_DIR/compaction-dual-summary-reproduction-20261016.tar.gz" -C "$REPRO_DIR"
PYTHONPATH="$PWD${PYTHONPATH:+:$PYTHONPATH}" python \
"$REPRO_DIR/compaction-dual-summary-reproduction-20261016/verify.py"
```
预期结果：**核验 3187 个产物哈希、546 个上下文和 1092 次评分；零 API 调用**。
产物包内的 `corpus/`、`evaluation/`、`native/`、`native-source/`、`combined/`、`final/` 对应
上述运行阶段。复用其中 H 摘要时传入 `--native-evaluation <bundle>/native-source`。

<summary>完整 query 与标准答案</summary>
初始 query 提供采集目标，后续问题要求返回下表的 JSON 字段；一个任务加一个后续问题仍是一个样本。
中文 query 为释义，英文原文见[英文版](./README.md#queries-and-expected-answers)；实际只读改写及字段说明以
[`suite.py`](./suite.py) 和冻结请求为准。标准答案的键、类型和英文字符串保持原样。
| ID | 初始 query 的中文释义 | 标准事实 | 分组 |
| --- | --- | --- | --- |
| payment | 调查原始支付重试事件。 | `{"incident_id": "PAY-4827", "invoice_id": "INV-731", "successful_charge_id": "CH-991", "amount_minor": 12900, "attempt_keys": ["pay-a", "pay-b"], "first_attempt_committed": true, "max_attempts": 3, "no_retry_http_statuses": [402, 422], "key_generation_line": 5, "regression_attempt_counts": {"timeout_then_success": 2, "validation_422": 1, "three_timeouts": 3}}` | 主任务 |
| backup | 从历史对话确认哪个仓库需要每晚备份，不要猜测；在工作区编写 backup.sh，将 repos/ 下该仓库归档，安排每天凌晨 2 点运行，用待办清单跟踪，并报告仓库与设置。 | `{"repo": "sparks-data", "ignored_repo": "toybox", "data_text": "important"}` | 对照：短来源 |
| refactor | 把 src/ 中所有 requests 调用的 timeout=30 改为 timeout=45，在 CHANGELOG.md 记录变更，并报告实际修改的调用点数量。 | `{"old_timeout": 30, "call_sites": 3, "functions": ["fetch_a", "fetch_b", "fetch_c"], "methods": ["get", "post", "head"], "old_version": "1.0"}` | 对照：短来源 |
| three_files | 用待办清单跟踪并核验：创建含 greet(name)、返回 `'hello <name>'` 的 greet.py；创建表头为 item,qty、含两行 widgets 数据的 data/rows.csv；创建说明新建文件数量的 notes/summary.md。完成并检查三项后再结束。 | `{"file_count": 3, "header": "item,qty", "data_rows": 2}` | 对照：仅依赖问题 |
| active_config | 在工作区查找 retry_limit 配置，并报告当前值。 | `{"retry_limit": 7, "backoff": 2, "active_file": "conf/app.ini", "old_file": "conf/old.ini"}` | 对照：短来源 |
| checkout_504 | 调查 checkout 504 事件，区分未奏效的回滚、根因及最终数据库修复。 | `{"setting": "statement_timeout", "value_seconds": 45, "index_mode": "CONCURRENTLY", "root_cause": "CREATE INDEX without CONCURRENTLY", "rolled_back_version": "v2.30.2", "rollback_fixed": false, "deployed_version": "v2.31.0", "initial_error_percent": 8}` | 主任务 |

| retry_backoff | 查找 src/ 中的重试延迟函数，解释基数、增长方式、上限与随机抖动。 | `{"base_ms": 250, "cap_ms": 30000, "growth_factor": 2, "jitter": "uniform_integer_below_bound", "function": "retryDelay"}` | 对照：短来源 |
| server_error | 定位服务器日志中唯一的 ERROR，保留精确请求标识、时间戳、上游和连接失败信息。 | `{"request_id": "req-7f3d9", "timestamp": "2026-08-08T23:41:17Z", "status": 502, "upstream": "payments", "error": "ECONNREFUSED", "address": "10.0.4.17:8443"}` | 主任务 |
| meeting_notes | 读取会议记录，准确报告第三条要点，并保留其他已商定行动。 | `{"third": "rotate the API keys quarterly", "first": "ship the payments retry fix", "second": "audit the staging TLS certs", "fourth": "close out the Q3 incident review"}` | 对照：短来源 |
| targeted_edit | 在 ./handlers.py 的三处 timeout = 10 中，仅将 slow_handler 内的一处用 patch 工具改为 timeout = 60；随后在当前目录运行 python3 check_handlers.py 并回复输出。 | `{"target": "slow_handler", "original_timeouts": {"fast_handler": 10, "slow_handler": 10, "medium_handler": 10}, "required_timeouts": {"fast_handler": 10, "slow_handler": 60, "medium_handler": 10}, "success_marker": "HANDLERS_OK_552"}` | 对照：短来源 |
| build_token | 运行输出很长的 python3 ./noisy_build.py，找出中间唯一以 UNIQUE_TOKEN= 开头的行，回复完整 token 值。 | `{"token": "tok_9f31c_middle", "step": 2000, "total_steps": 4000, "prefix": "UNIQUE_TOKEN="}` | 主任务 |

<summary>协议修正、审计与历史产物</summary>
初始七组的 588 次回答暴露两处格式说明歧义：支付测试次数返回为数组，会议要点带列表标记。
标准答案和评分器不变，仅明确支付次数须用指定键的 JSON 映射、会议要点不带列表标记。
两任务的七种方法使用原有 S／排名统一重答，初始 84 次作为预检排除；其他 12 个任务保留 504 次回答。
随后纯 H 新增 84 次，H 融合新增 420 次，组成当前最终结果；全部 42 份 H、排名及已有 672 次回答被复用。
分组、证据、答案值均未因结果调整。
H 首次强制生成包含长控制前缀，40/42 个输入超过 Full，仅作为集成预检保留。
正文封装和字数约束在新的评分回答前固定，不改动 S、标准答案、分组或 Jev 排名。
H 使用格式修正前的来源文件，两版本只有不发送给生成器的 `exam` 字段不同。
支付任务早期 `budget.json` 为 4459；最终问题增加 37 tokens，最终 `results.json` 的 4496 是评分上限。
冻结文件保留原貌，不回写修改。
离线审计核验来源哈希、固定 S／H、相同且嵌套的 Top-N 原文、实际输入、全部评分、输入上限、
已有结果未变与配置密钥未泄露；全部 546 个条件有效。原始文件、会话、API 请求／响应、代码快照和逐字段评分不进入 Git。
历史目录位于 `/Users/yuli/workspace/trajectory-runs/`：
`hermes-fixture14-20261016/`（语料）、`compaction-fixture14-20261016-v2/`（S／排名）、

# Context compaction with decision models
`compact_context` proposes recoverable previews of old tool results. It scores evidence for the current task,
keeps tool calls and uncertain evidence, and leaves source history under the host's control. The provider-independent
`as_decision_model` interface currently supports AgentScope's TypeSafe/Jev adapter.
![Evidence, conservative selection, budget fitting, and source recovery](../figure/decision-context-compaction.svg)
## How it works
1. **Archive first.** Supply an AgentScope 2.x JSON message snapshot, `goal`, optional `next_action`, a read-only tool
allowlist, and `source_refs` mapping original call IDs to recoverable archive locations. References are opaque host
identifiers: ReMe does not open, verify, or create them. The host must archive before applying a proposal and provide
a retrieval tool that resolves them. No reference means no compaction for that pair.
2. **Protect structure and indispensable evidence.** Pair unique `tool_call` / `tool_result` IDs. First, system, recent,
explicitly protected messages and calls stay intact. Failed/unfinished calls, non-text results, invalid inputs,
mismatched tool names, and ambiguous pairs stay intact. `eligible_tool_names` defaults to empty.
3. **Show bounded evidence.** Each request contains its own candidate units: tool name, input, result head/tail preview,
character count and completeness flags. It also carries the goal, next action and bounded first/system/protected/recent text. Thinking is
not sent. Hosts must sanitize inputs and outputs before inference; previews may contain source data.
4. **Ask one question per pair.** Does this evidence contain information needed to continue correctly? The question
measures usefulness, not irrecoverability. Missing or truncated context expresses uncertainty. Oversized units are
left unobserved and retained; they are never scored after their evidence has been removed.
5. **Replace only clearly unnecessary results.** At probability `<= drop_threshold` (default `0.1`), a result can become
a verbatim head/tail excerpt plus its source reference. Higher, invalid, or missing probabilities retain the result.
Provider errors and timeouts retain the affected evidence; external cancellation propagates after requests drain.
No tool call or message is deleted. Replacements occur only when shorter. User/assistant text, thinking, metadata and
source inputs remain unchanged. Explicitly protect constraints, audit receipts and unique evidence; probabilities are
not substitutes for host protection rules. The threshold is a conservative starting point, not a calibrated guarantee.
## Configure and call
```bash
pip install "reme-ai[core,decision]"
export DECISION_MODEL_API_KEY=your-typesafe-api-key
export DECISION_MODEL_BACKEND=agentscope
# Optional: DECISION_MODEL_NAME and DECISION_MODEL_BASE_URL
```
The CLI also loads `DECISION_MODEL_*` from `.env`. See [configuration](./configuration.md#decision-model-configuration).
An omitted or `null` model uses the SDK default.
Start the service in one terminal:
```bash
reme start config=decision_compaction
```
Call from another terminal, using references the host has already archived and can resolve:
```bash
reme compact_context \
goal='Fix payment retries' next_action='Review the retry implementation' \
eligible_tool_names='["search_code"]' source_refs='{"c1":"archive/demo/c1"}' \
options='{"preserve_recent_messages":1}' \
messages='[{"role":"user","content":[{"type":"text","text":"Fix retries"}]},{"role":"assistant","content":[{"type":"tool_call","id":"c1","name":"search_code","input":"{\"path\":\"icons\"}","state":"finished"},{"type":"tool_result","id":"c1","name":"search_code","output":"Old icon search results","state":"success"}]},{"role":"user","content":[{"type":"text","text":"Inspect payment code next"}]}]'
```
A short result may remain unchanged when adding the recovery marker would make it larger.
The preset inherits the default service and background jobs. For embedding, assemble only the compaction job/component
as shown in [integration tests](https://github.com/agentscope-ai/ReMe/blob/main/tests/integration/test_decision_compaction.py).
## Host token budget
Decision request estimates and downstream input budgets are separate. To enforce `max_output_tokens`, embed the Step
with a synchronous `token_counter(messages)` that counts the host's actual serialized model input, including system
instructions, tool schemas and framing. The counter must return a non-negative integer; configuration without a counter
fails before inference. ReMe's search tokenizers are not model token counters.
```python
step = CompactContextStep(as_decision_model=decision_model, token_counter=count_model_input)
response = await step(
messages=snapshot,
goal="Fix retries",
next_action="Review the patch",
source_refs=archive_refs,
eligible_tool_names=["read_file"],
options={"max_output_tokens": 32000},
)
```
Already within budget means no model requests. Otherwise eligible low-probability results are previewed in increasing
probability order until the budget is met. A replacement must reduce both size and the host count. Required/uncertain
content is never removed to force a fit. If it still does not fit, `reason="budget_exceeded"` and `budget_met=false`:
use host summarization or another fallback before applying. Without a requested budget, all eligible low-probability
results may be previewed and `budget_met` is `null`; the host must check the final input itself.
## Contract and defaults
The standard Response `answer` has `schema_version=2`, proposed `messages`, `changed`, `reason`, `budget_met`, `decisions`
and `stats`. Each decision has the original `call_id`, internal `id`, `action` (`keep` / `preview`), `probability`, `reason`
and `source_ref`. Reasons distinguish protection, uncertainty, unobserved evidence, invalid answers, provider errors,
timeout and no savings. Statistics include before/after sizes and host token counts, candidate/protection counts,
maximum estimated batch-state tokens, request count, usage and elapsed time. Statistics also appear in response metadata.
| Option | Default | Meaning |
| --- | --- | --- |
| `drop_threshold` | `0.1` | Preview only results at or below this probability |
| `preserve_recent_messages` | `6` | Protect this many recent messages |
| `evidence_chars` | `2000` | Maximum characters per input/result preview or recent text |
| `preview_chars` | `300` | Maximum head/tail excerpt in the proposed result, excluding recovery marker |
| `max_state_tokens` | `25000` | Estimated decision-state ceiling |
| `max_request_tokens` | `30000` | Estimated state/questions ceiling, including 256 tokens of overhead |
| `max_output_tokens` | `null` | Optional host-counted input budget |
| `max_concurrency` | `4` | Maximum concurrent decision requests |
| `total_timeout_seconds` | `30` | Overall request and queueing deadline |
The integration suite contains two synthetic scenarios: payment retry debugging and replica-lag investigation, with
important source/log evidence competing against completed unrelated tasks. Run explicitly with configured credentials:
```bash
REME_RUN_DECISION_INTEGRATION=1 pytest tests/integration/test_decision_compaction.py -v -s
```
Only model requests run externally; fixture tool calls are not executed. These cases test behavior, not general task
success. Evaluate real trajectories against recency and rule-based previews, measuring recovery, continuation quality,
latency alongside token reduction. ReMe does not automatically summarize or write persistent memory.
## Jev across two summary strategies
### Background
Summaries shorten history but can omit exact identifiers, configuration values or log details needed for a later answer.
This experiment asks: **can a few Jev-selected original evidence blocks recover information missing from a fixed summary,
and does that benefit occur with both a generic summary and a Hermes summary?** Exact-field score and Qwen answer input show the
tradeoff between retained information and context length.
### Experimental setup
| Item | Recorded setting |
| --- | --- |
| Data | 14 synthetic task templates with predefined queries/answers: one existing payment trajectory and 13 actual read-only Hermes executions. Four primary tasks were selected by source length before collection: payment retries, checkout 504, server-error localization and build-log token lookup. Ten short/query-only controls are reported separately. |
| Framework and models | Hermes Agent `AIAgent`, pinned to `30463589eb54`; **`qwen3.8-max`** for collection, both summary mechanisms and answering. **`jev-1.13.0`** through AgentScope **2.0.10** ranks evidence. Hermes collects trajectories; evaluation calls Qwen directly. |
| Summary mechanisms | **S** uses a generic handoff-summary prompt. **H** is Hermes compaction summary under a small-budget setting: its `legacy` generation pipeline with adjusted budget/length constraints. Summary generation is invoked directly, bypassing automatic triggering and head/tail selection. |
| 13 methods | **Full context** retains all pre-evaluation history. **S + Top 0–5** and **H + Top 0–5** each contribute six methods. Top 0 is summary only; Top N appends N whole evidence blocks. Both curves share identical Jev selections; each generation freezes S/H byte-for-byte. |
| Budget | Forced small-budget simulation: summary-body allowance **64–256 tokens**, derived from evidence length; complete answer-input ceilings are task-specific. Larger N retains more evidence, so lengths differ. Full is an uncompressed reference; it need not exceed every case ceiling. |
| Evaluation | Summarization/ranking receives the original task and evidence, never the held-out questions or gold. Final collection reports are excluded. Answers return JSON and are scored with predefined type-strict field rules, **without an LLM judge**. Average within tasks, then weight tasks equally. |
| Repeats and size | Three summary/ranking generations per task, two answers per context: **546 contexts / 1,092 answers**. The figure shows four primary tasks, 24 answers per method; repeated answers are not additional tasks. Summary/answer temperature is 0, with thinking disabled. |
Jev scores all available evidence against the original task once; N changes the number retained, not ranking-call count.
This is a gold-answer **information-retention evaluation**, without resuming Hermes' tool loop to complete the task.
### Reading the figure and conclusions
![Answer quality and downstream input across two summary strategies](../figure/compaction-topn-results.svg)
- **A: selected originals help both summary mechanisms on this panel.** Full scores 100%; Top 3 improves S from
**82.0% to 99.5%**, and H from **79.4% to 97.9%**. This supports supplementing these summaries with original evidence;
it does not establish general superiority or statistical equivalence to Full.
- **B: higher retention consumes more context than summary alone.** Top 3 uses **3,241 / 3,193** mean answer-input tokens
for S/H, versus Full's **4,014**, reductions of **19.3% / 20.4%**. Both exceed their summary-only input. Top 4–5 do not
improve the scores: more original text does not guarantee better answers.
**Scope:** the primary result covers four synthetic task templates; ten controls are separate. All 42 H-only contexts
shorten Full, but Top 3–5 shorten only **9/12 primary contexts per method**, with every case still scored. Strict field scoring includes format compliance; semantically equivalent wording can still lose credit.
The result shows an information/length tradeoff. Without equal-length longer-summary or alternative-selector controls,
the entire gain cannot be attributed to Jev ranking itself. Agent continuation success remains unmeasured.
<!-- Payment has 10 units (maximum Top 10); actual N is min(N, available units). -->

`as_decision_model` 是不依赖供应商的概率决策模型接口；当前的 `agentscope` 适配器通过 AgentScope `2.0.10` 调用 TypeSafe API。

pip install "reme-ai[core,classifier-jev]"
pip install "reme-ai[core,decision]"
# 从源码安装时：
pip install -e ".[core,classifier-jev]"
pip install -e ".[core,decision]"

# 基于决策模型的上下文压缩
`compact_context` 为旧工具结果生成可恢复的预览建议：判断证据对当前任务是否仍有用，保留工具调用和不确定的证据。
原始历史由宿主持有。流程使用通用 `as_decision_model` 接口，当前 `agentscope` 适配器连接 TypeSafe/Jev。
![证据观测、保守选择、预算检查和原文恢复](../figure/decision-context-compaction.svg)
## 一次压缩如何工作
1. **宿主先归档。** 提供 AgentScope 2.x JSON 消息、`goal`、可选的 `next_action`、只读工具允许列表，以及
`source_refs`：原始调用 ID 到归档来源的映射。引用是宿主定义的标识；ReMe 不打开、验证或创建归档。
宿主必须在应用建议前保存原始历史，并提供能根据引用取回原文的工具。没有引用的配对不参与压缩。
2. **确定性保护。** 按唯一 ID 配对 `tool_call` 和 `tool_result`。第一条、system、最近和显式保护的消息及调用保留。
未完成或失败的调用、非文本结果、非法输入、工具名不一致和不明确的配对保留。`eligible_tool_names` 默认为空。
3. **展示有界证据。** 每批只携带本批候选的工具名、输入、结果头尾片段、字符数和完整性标记，同时携带目标、
下一步行动和有限的首条、system、保护及近期文本。thinking 不发送。预览可能包含源码等数据，宿主应在推理前处理敏感内容。
4. **每对一个问题。** 判断“这份证据是否包含继续正确执行任务所需的信息”，不再判断能否重新获取。
截断或缺失信息代表不确定。单个证据放不进请求预算时保留，不移除观测内容后继续盲判。
5. **只替换明确无关的结果。** 概率 `<= drop_threshold`（默认 `0.1`）时，允许替换为原文头尾片段和恢复引用。
更高概率、缺失或非法答案保留原文。供应商错误和超时保留受影响证据；外部取消在请求清理后向上传播。
工具调用和消息都不删除。新结果只有更短时才替换。用户与 assistant 文本、thinking、元数据和输入原文不改变。
不可丢失的约束、审计回执和关键证据应显式保护，不能只依赖概率。默认阈值是保守起点，不代表已经校准。
## 配置与调用
```bash
pip install "reme-ai[core,decision]"
export DECISION_MODEL_API_KEY=your-typesafe-api-key
export DECISION_MODEL_BACKEND=agentscope
# 可选：DECISION_MODEL_NAME、DECISION_MODEL_BASE_URL
```
CLI 也从 `.env` 读取 `DECISION_MODEL_*`，详见[决策模型配置](./configuration.md#决策模型配置)。
省略模型名或配置为 `null` 时使用 SDK 默认模型。
在一个终端启动服务：
```bash
reme start config=decision_compaction
```
在另一个终端调用，引用应已由宿主归档并能够解析：
```bash
reme compact_context \
goal='修复支付重试' next_action='检查重试实现' \
eligible_tool_names='["search_code"]' source_refs='{"c1":"archive/demo/c1"}' \
options='{"preserve_recent_messages":1}' \
messages='[{"role":"user","content":[{"type":"text","text":"修复重试"}]},{"role":"assistant","content":[{"type":"tool_call","id":"c1","name":"search_code","input":"{\"path\":\"icons\"}","state":"finished"},{"type":"tool_result","id":"c1","name":"search_code","output":"旧图标搜索结果","state":"success"}]},{"role":"user","content":[{"type":"text","text":"接下来检查支付代码"}]}]'
```
短结果可能因为恢复标记反而更长而保持不变。配置继承默认服务和后台 Job；嵌入宿主时，可参考
[集成测试](https://github.com/agentscope-ai/ReMe/blob/main/tests/integration/test_decision_compaction.py)只装配压缩 Job 与决策组件。
## 主模型 token 预算
决策请求的估算预算与压缩后主模型输入预算独立。使用 `max_output_tokens` 时，宿主必须在构造 Step 时注入同步函数
`token_counter(messages)`，按实际模型输入格式计算 token，包含 system、工具定义和消息封装。函数必须返回非负整数。
缺少计数函数时在推理前报错。ReMe 的检索分词器不能代替模型 token 计数器。
```python
step = CompactContextStep(as_decision_model=decision_model, token_counter=count_model_input)
response = await step(
messages=snapshot,
goal="修复重试",
next_action="检查补丁",
source_refs=archive_refs,
eligible_tool_names=["read_file"],
options={"max_output_tokens": 32000},
)
```
已经满足预算时不调用模型。否则只在低概率候选内按概率从低到高替换，满足预算即停止；替换必须同时减少文本大小和
宿主 token 计数。不会为了满足预算删除必要或不确定的证据。仍然超限时返回 `reason="budget_exceeded"`、
`budget_met=false`，宿主应先执行摘要等后续策略。未指定预算时处理所有符合条件的低概率结果，`budget_met=null`，
由宿主自行检查最终输入。
## 返回值与默认配置
标准 Response 的 `answer` 包含 `schema_version=2`、建议 `messages`、`changed`、`reason`、`budget_met`、
`decisions` 和 `stats`。每个决策记录原始 `call_id`、内部 `id`、动作 `keep` / `preview`、`probability`、
`reason` 和 `source_ref`。原因区分保护、不确定、未观测、非法答案、供应商错误、超时和没有节省。
统计包括前后大小及宿主 token 数、候选和保护数量、最大批次状态估算 token、请求数、usage 和耗时，也写入响应元数据。
| 配置 | 默认值 | 含义 |
| --- | --- | --- |
| `drop_threshold` | `0.1` | 只有不高于此概率的结果允许替换为预览 |
| `preserve_recent_messages` | `6` | 保护最近的消息数 |
| `evidence_chars` | `2000` | 每个输入、结果预览或近期文本的字符上限 |
| `preview_chars` | `300` | 建议结果保留的头尾片段字符上限，不含恢复标记 |
| `max_state_tokens` | `25000` | 决策状态的估算上限 |
| `max_request_tokens` | `30000` | 状态和问题的估算上限，含 256 token 额外预留 |
| `max_output_tokens` | `null` | 可选的宿主计数预算 |
| `max_concurrency` | `4` | 最大并发请求数 |
| `total_timeout_seconds` | `30` | 包含排队的总体请求超时 |
## 验证
两个集成场景分别模拟支付重试排障和副本延迟调查，让重要源码、日志与已经结束的无关任务竞争。
配置凭证后显式运行：
```bash
REME_RUN_DECISION_INTEGRATION=1 pytest tests/integration/test_decision_compaction.py -v -s
```
只有模型请求调用外部服务，历史中的工具不会执行。这些用例验证行为，不证明通用任务成功率。
真实 trajectory 评测应对比近期保留和纯规则预览，同时测量恢复次数、继续执行的质量、时延和 token 节省。
ReMe 不会自动生成摘要或写入长期记忆。
## 两种摘要机制下的 Jev 增益
### 实验背景
摘要可以缩短历史，但可能丢失后续回答需要的精确标识符、配置值或日志细节。本实验考察：**在摘要保持不变的基础上，
追加 Jev 选出的少量原文，能否补回这些信息？这一增益能否同时出现在普通摘要和 Hermes 摘要中？**
同时报告字段正确率和 Qwen 回答输入量，观察信息保留与上下文长度之间的取舍。
### 实验设置
| 项目 | 本次设置 |
| --- | --- |
| 数据 | 14 个预设 query/answer 的合成任务模板：1 条已有支付轨迹，另用 Hermes 实际采集 13 条只读轨迹。按来源长度预先确定 4 个主任务：支付重试、checkout 504、服务器错误定位、构建日志 token 查找；10 个短任务／query-only 对照单独报告。 |
| 框架与模型 | Hermes Agent `AIAgent`，版本固定为 `30463589eb54`；采集、两种摘要和最终回答均使用 **`qwen3.8-max`**。Jev 为 **`jev-1.13.0`**，通过 AgentScope **2.0.10** 调用。采集使用 Hermes，评分阶段直接调用 Qwen。 |
| 两种摘要 | **S**：通用任务交接摘要提示词。**H**：Hermes 上下文压缩摘要（小预算版），复用其 `legacy` 摘要生成流程，调整预算和长度约束；实验直接生成摘要，不经过自动触发和首尾窗口选择。 |
| 13 个对照组 | **Full context** 保留完整的评测前历史；**S + Top 0～5** 和 **H + Top 0～5** 各 6 组。Top 0 是纯摘要；Top N 在原摘要后追加 N 个完整证据块。两条曲线使用相同 Jev 排名和原文，每轮的 S／H 均逐字固定。 |
| 压缩预算 | 主动压缩的小预算模拟：摘要正文上限按证据长度设为 **64～256 tokens**；完整回答输入上限按任务计算。N 增大时保留更多原文，实际输入随之变化，各组并非等长比较；Full 是无压缩参考，不要求每个任务都超过该上限。 |
| 评测 | 原任务和证据用于摘要／排序，评测问题与标准答案不提供给它们；最终采集报告也排除。回答需返回 JSON，按预设字段的严格类型和值规则评分，**不用 LLM judge**。分数先在任务内平均，再对任务等权平均。 |
| 重复与规模 | 每个任务 3 轮摘要／排名，每个上下文回答 2 次；共 **546 个上下文、1092 次回答**。主图只展示 4 个主任务，每种方法 24 次回答；重复回答不等于新增任务。摘要和回答温度为 0，关闭 thinking。 |
Jev 先依据原任务给全部证据块打分，再选择 Top N；N 只影响保留数量，不增加排名调用次数。
这是预设标准答案的**信息保留评测**，没有让 Hermes 在压缩后继续调用工具完成任务。
### 读图与结论
![Answer quality and downstream input across two summary strategies](../figure/compaction-topn-results.svg)
- **A：两种摘要都能从追加原文中获益。** Full 的字段正确率为 100%；Top 3 将 S 从 **82.0% 提升至 99.5%**，
将 H 从 **79.4% 提升至 97.9%**。这支持“摘要 + 关键原文”在本组任务中补充摘要遗漏的信息，尚不能证明通用优势或与 Full 统计等价。
- **B：以更多上下文换取更高的信息保留率。** Top 3 的平均回答输入为 S **3241**、H **3193 tokens**，
相比 Full 的 **4014 tokens** 分别减少 **19.3%／20.4%**，但都高于各自纯摘要。Top 4～5 未继续提分，更多原文不保证效果更好。
**结果边界：** 主结论来自 4 个合成任务模板；10 个短任务对照不混入主图。纯 H 的 42 个上下文均短于 Full，
但 Top 3～5 每种方法仅有 **9/12 个主任务上下文**实际缩短，全部样例均保留评分。严格字段评分包含格式要求，语义相同但格式不同也可能失分。
当前结果展示了信息保留与长度的取舍；尚未加入等长度的更长摘要或其他选择器对照，不能将全部增益归因于 Jev 排序本身。
agent 继续执行的成功率尚未验证。
<!-- 支付轨迹有 10 个证据块，最多 Top 10；实际 N 为 min(N, 可用证据块数)。 -->
