+# AAMAS 官方论文集元数据
+
+`paper_atlas.collectors.aamas` 是按需运行的采集适配器，通过统一入口 `collect aamas-proceedings` 使用。目前只支持已独立核验的 **AAMAS 2012** HTML 版式；其他年份需先核对官方目录和逐篇结构，再增加适配，不能仅替换年份。
+
+## 来源与范围
+
+[官方论文集介绍](https://www.ifaamas.org/Proceedings/aamas2012/)及其 Full Papers、Extended Abstracts、Demos、Doctorial Consortium Abstracts 四个栏目分别列出 136、146、28、24 条，共 334 条。旧 DBLP 候选卷的 310 条不能替代这四类官方目录，也不能全部标记为主会全文。栏目数量来自 2026-11-09 冻结的原始页面；页面结构或数量发生变化时，采集器停止，留待重新核验。
+
+采集标题、逐篇作者、页面实际提供的摘要、官方条目 ID、目录锚点和 PDF 地址。**只保存 PDF 链接，不下载 PDF。** 全文页面的摘要藏在标题链接内部的 `abstract` 元素，作者链接里的 “has N papers” 是界面徽标，二者不会混入标题或姓名。未提供的摘要保存为 `null`，不会用标题、说明文字或其他论文填充。
+
+官方介绍说明了 general、robotics、virtual agents、innovative applications 等投稿轨道，但逐篇目录的主题会话不能独立证明某篇论文的投稿轨道。因此全文和扩展摘要均使用 `proceedings_unspecified`；演示、博士栏目使用 `demo`、`doctoral`。发表形式保留在 `metadata.publication_format` 和 `aamas_proceedings:publication_format` 标签中，会话原文单独保存。它们不是研究类型标注，也不会写入自定义 annotation。
+
+目录条目仅提供发表录用证据，不是原始决定信。`observed_at` 是页面采集时间，不能当作 2012 年的决定日期；官方介绍中的投稿、撤稿、录用汇总数不能识别逐篇拒稿或撤稿，采集器不会由总量相减生成这些决定。
+
+## 运行
+
+在已确认的远程运行环境中，使用 HTTP 缓存采集：
+
+```sh
+paper-atlas collect aamas-proceedings --year 2012 \
+  --cache /data/paper-index/cache/aamas \
+  --out /data/paper-index/collected/aamas-2012
+```
+
+也可使用已冻结的官方页面：
+
+```sh
+paper-atlas collect aamas-proceedings --year 2012 \
+  --snapshots /data/paper-index/collected/historical-next-source-evidence-v1 \
+  --out /data/paper-index/collected/aamas-2012
+```
+
+快照目录需含 `receipts.json`，其中每个响应包含原始 `url`、HTTP `status`、相对 `file`、`bytes`、`sha256` 和 `finished_at`。要求五个准确官方 URL 均唯一匹配且返回 200；验证全部字节数和哈希后才解析，不接受目录穿越或绝对文件路径。快照中其他来源的响应不会被当成 AAMAS 页面。
+
+输出为按数据库 track 分组的三个 JSONL 文件和对应 manifest、五份原始 HTML 证据，以及最后写出的 `aamas-proceedings-2012.json` 采集报告。锁文件避免同一输出目录并发运行。manifest 始终为 `partial`，记录发表形式数量和缺失摘要数；**采集命令不连接数据库，也不导入。**
+
+## 复核与恢复
+
+每条记录携带对应官方页面的 URL、采集时间、字节数、SHA-256 与输出内证据路径。重新运行前先检查已有采集报告和文件哈希；采集中断不等于主库已导入，报告缺失或哈希不一致的目录不能直接作为导入队列。输出中的原始证据应随文件一起保存。
+
+生产导入前仍需单独与主库核验稳定标识、标题、作者及已有投稿，按证据补充 DOI/arXiv 等标识；目录页上的作者计数徽标和会话 ID 不能作为这些标识。需要另建经过核验的增量清单、保护旧历史，完成独立验收后才能计入覆盖。跨来源同一论文不得仅因同题就新增或合并投稿。
+
+本功能的代码、测试或采集成功均不代表 AAMAS 2012 已导入生产，也不证明拒稿全集完整。全库最终去重、摘要和来源覆盖验收属于独立后续阶段。

+# Research types and custom annotations
+
+Research type describes a claimed characteristic of the work (for example a survey,
+benchmark, empirical study or replication). It is independent of topic, paper length,
+conference track, presentation format and acceptance status. No type is inferred from
+those fields. Multiple source-specific or human classifications may coexist; no
+cross-platform vocabulary mapping or automatic classifier is provided.
+
+`annotation_events` stores both kinds with an explicit `kind` discriminator:
+`research_type` and `tag` are separate domains, even when namespace/value strings
+happen to coincide. Existing platform labels remain in `tags` / `paper_tags`.
+Each assertion carries namespace, value, actor, reason, evidence key, optional source
+record and evidence URL, and the time it was recorded. This is observation time, not
+paper publication time or a conference decision date.
+
+Values are not forced into a global taxonomy: `custom:method=empirical` and
+`platform:declared_type=empirical` retain separate provenance. An explicit platform
+assertion API requires a source record belonging to that paper and matching the
+namespace prefix. The manual CLI only accepts `custom:*`, and cannot retract platform
+assertions. No source type has been automatically assigned to existing papers.
+
+## Initialize explicitly
+
+On the published PostgreSQL dataset, using its protected service file:
+
+```sh
+PGSERVICEFILE=/etc/paper-atlas/pg_service.conf paper-atlas annotate init \
+  --pg-service foundry-research --pg-schema research
+```
+
+This creates one optional table, its indexes, and an upgrade marker in one transaction,
+using the existing dataset writer lock. It does not copy data, change existing papers
+or decisions, or create a PostgreSQL instance. Repeating it is safe; an unexplained
+pre-existing table/marker mismatch fails closed. Readers and ordinary imports do not
+install the extension. Legacy datasets remain readable. A SQLite **sample** uses
+`--db sample.sqlite`; the cutover SQLite backup remains protected against writes.
+
+## Add and retract evidence
+
+Use the canonical paper ID returned by `query`. For a reviewed classification:
+
+```sh
+paper-atlas annotate assert --pg-service foundry-research --pg-schema research \
+  --paper "$PAPER_ID" --kind research_type --namespace custom:method \
+  --value empirical --evidence-key manual:abstract-review \
+  --actor reviewer --reason 'Classified from the explicitly described study design' \
+  --request-id "$REQUEST_ID"
+```
+
+`$REQUEST_ID` must be a new, stable identifier for this action (for example a UUID).
+Retry with the same request ID and identical content after an interrupted response;
+it returns the original event ID. Reusing that ID with changed content is rejected.
+A topic annotation uses `--kind tag --namespace custom:topic --value robotics` instead.
+Optional `--source-record` and `--evidence-url` attach additional evidence; the source
+record must belong to this paper. URLs are retained as evidence and are not fetched.
+
+To withdraw one particular assertion, use its returned event ID:
+
+```sh
+paper-atlas annotate retract --pg-service foundry-research --pg-schema research \
+  --event "$EVENT_ID" --actor reviewer --reason 'Classification corrected after review' \
+  --request-id "$RETRACTION_REQUEST_ID"
+```
+
+Retraction adds an event referencing that assertion, preserving its original content.
+It does not remove another contributor's assertion of the same label, platform tags,
+source metadata or submission/decision history. A retracted assertion can be asserted
+again with a new request ID and evidence; it is a new observation. The API does not
+update or delete past annotation events. Database administrators still control direct
+SQL access. Work reviewed as the same paper may subsequently be merged by the existing
+identity workflow: annotation IDs, original paper IDs, evidence and retraction links
+are retained while the canonical paper reference follows the surviving entity.
+
+## Query and analyze
+
+```sh
+paper-atlas query --pg-service foundry-research --pg-schema research \
+  --research-type custom:method=empirical
+paper-atlas query --pg-service foundry-research --pg-schema research \
+  --tag custom:topic=robotics
+paper-atlas query --pg-service foundry-research --pg-schema research \
+  --paper "$PAPER_ID" --annotation-history
+paper-atlas annotate list --pg-service foundry-research --pg-schema research \
+  --paper "$PAPER_ID" --history
+```
+
+`--tag` includes original platform labels and active annotation tags. It never matches
+research types. `--research-type` matches active type assertions only. Paper details
+return separate `tags` (existing provenance), `annotation_tags`, and `research_types`;
+`--annotation-history` additionally includes retractions. A missing extension yields
+empty annotation results rather than changing the database.
+
+For direct SQL analysis, active research-type evidence is:
+
+```sql
+SELECT a.* FROM research.annotation_events a
+WHERE a.kind = 'research_type' AND a.retracts_id IS NULL
+  AND NOT EXISTS (SELECT 1 FROM research.annotation_events r WHERE r.retracts_id = a.id);
+```
+
+Several independent assertions can support one label; count distinct papers/labels
+when appropriate rather than counting evidence rows as papers. Namespaces stay
+separate. Standard paper queries decode the PostgreSQL text codec; direct SQL consumers
+must honor the dataset's documented codec, including NUL/SOH values. SQLite-to-PostgreSQL
+migration recognizes an installed annotation extension and verifies its full row hashes,
+constraints and identity sequence along with the original business tables. An old
+21-table snapshot stays a 21-table migration; no synthetic annotations are generated.

+# 历史年度缺口的当前核对
+
+生产只读快照：2026-11-08 16:34:40.741334 UTC（北京时间11月9日00:34），foundry_data/research。对比已核实的43份首轮官方会议年度清单，使用当前有投稿记录的edition及真实venue_aliases，不沿用旧固定快照的missing_years。
+
+- 清单共1266个会议—年份位置，当前有150个位置尚无投稿记录，涉及25个目标会议。
+- 其中2025年及以前136个；排除已明确非存档的SysML2018首届，剩**135个历史年度待补采或核实，涉及16个会议**。
+- 另有14个2026年度待核实。已知NeurIPS2026和CoRL2026在首轮核查时尚未进入论文集索引，不能一律当已公开论文遗漏；其他年度也需逐个核实发布时间。
+
+这些是“整年没有任何投稿记录”的数量，不是缺论文篇数，也不是完整性百分比。一个年份只有少数记录、只有公开拒稿或缺了某个track，仍会被计作“已有年度”；这些更细缺口及公开拒稿的逐年可获得性尚须继续核验。会议别名共享的联合届次不能当成两批独立论文，未见录用也不能推断拒稿。
+
+| 会议 | 历史缺口年份数 |
+| --- | ---: |
+| ICML | 29 |
+| CVPR | 25 |
+| ACL | 16 |
+| ECCV | 14 |
+| ICCV | 13 |
+| ICAPS | 8 |
+| WWW | 6 |
+| ECML-PKDD | 5 |
+| AISTATS | 4 |
+| ICLR、COLING、IROS | 各3 |
+| ECAI、AAMAS | 各2 |
+| RSS、ICASSP | 各1 |
+
+[完整逐年结果](historical-gaps-2026-11-09.json) 保留43目标的官方预期、现有年份数、缺失年份与规范会议匹配。原始只读生产导出保存在 `/data/paper-index/collected/historical-gap-current-20261109-v1.json`。 导出SHA256 `580cdea6dd9869adafe9bc28fb75cf3854bb290ad65aa5a600d9bc368a528b93`。年度对照清单为 `docs/coverage/inventory-2026-11-08.json`；候选来源文件绑定的输入哈希与本目录缺口JSON逐字节一致。来源清单的年份和哈希沿用相应 `*-editions-2026-11-08.json`，不是本轮重新访问所有会议网站；2026发布状态需要后续更新。
+
+## 候选来源与下一步
+
+另一次只读目录核查在现有、已校验的DBLP快照中，为135个历史年度中的**85个**匹配到初步候选论文集，另**50个**尚未按本轮规则匹配到，需要继续识别目录键或寻找官方来源。未匹配不等于会议没举办、未出版或没有公开来源。
+
+[候选卷清单](historical-source-candidates-2026-11-09.json) 保留卷key、标题、出版年份、原始bibliographic counts和出版者链接。初筛使用目标family映射内的四位卷key年份或卷标题唯一显式年份，再按具体会议身份复核；两位键、出版年份与会议年份差异、前身系列及其他目录命名可能漏匹配。原始计数可能含workshop、前言、索引或多个卷，**不能当可直接导入的录用论文数量**。
+
+后续[来源范围复核](historical-source-scope-2026-11-09.md)排除了4个误归ACL的COLING卷，因此候选年度由89修正为85、未匹配年度由46增至50。原卷及排除理由保留在JSON中；135个历史年度缺口不因此改变。ACL1963–1978与COLING1971/1976/1978在当前Anthology目录未列出，继续记为来源待核实，不能一律称作已公开但漏采的论文集。
+
+优先核查已有候选卷较集中的CVPR22年、ICCV12年、ECCV14年和ICML25年。其中ICML早期workshop名称可能属于官方主系列前身，也可能是附属workshop，须对照官方届次证据逐卷区分，不能靠标题包含workshop一刀切。所有候选须经过范围、稳定标识、重复/冲突、原始字段和覆盖预检；这一步没有导入候选卷。
+
+## 复核方法
+
+只读获取当前有记录的edition，不连接papers大文本或标签表：
+
+```sql
+WITH counts AS (
+  SELECT edition_id,count(*) AS submissions
+  FROM submissions GROUP BY edition_id
+)
+SELECT e.id,e.venue_id,v.acronym,e.year,e.track,e.event_key,counts.submissions
+FROM editions e JOIN venues v ON v.id=e.venue_id
+JOIN counts ON counts.edition_id=e.id ORDER BY e.id;
+
+SELECT venue_id,alias FROM venue_aliases ORDER BY venue_id,alias;
+```
+
+逐目标取规范会议名或别名相等的edition年份集合，与该目标edition_census.expected_years做集合差；再把2026与明确非存档的SysML2018单列。保留原始导出与校验哈希，不把每个matched year误当逐篇/逐track完整。
+
+与本清单同一阶段的WWW补采只补1995年现有poster轨道，不新增缺失年度，所以即使其15条增量已验收，135这个年度计数也不会随之下降。早期1994年的50条正式展示候选、307条混合节目候选共357条仍需核实；其中并非每条都是论文。
+
+本清单用于明确第14步剩余范围，不代表第14步完成，也不替代所有导入结束后的第16步全库去重、摘要、约束和实际查询验收。

+# ICML 与 IROS 早期主系列的来源范围
+
+本轮修正采集阶段的届次识别，不修改任何现有生产投稿轨道或历史。正式主系列曾以Workshop命名，不等于附属workshop；也不能反过来把所有旧workshop升为主会。
+
+## 已核实的精确范围
+
+| 会议 | 论文集键 | 依据与行为 |
+| --- | --- | --- |
+| ICML | `conf/icml/1988`、`1989`、`1990`、`1991`、`1992` | [官方历史](https://icml.cc/Conferences/2008/past_icmls.shtml.html)将其列为第5–9届，年份与举办地对应固定目录中的完整标题。1989/1991/1992的Workshop名称不再导致主系列被默认排除；1988/1990保留main并增加来源范围证据 |
+| IROS | `conf/iros/1988`、`1989`、`1990` | [IEEE RAS官方历届目录](https://www.ieee-ras.org/conferences-workshops/financially-co-sponsored/iros/iros-past-and-future-venues/)列出三届与论文集链接，地点及日期对应固定目录标题；这些是IROS主系列 |
+
+规则同时要求family、booktitle基础别名（ML或IROS）、空轨道后缀、完整精确论文集键、匹配的事件年份及固定完整标题。仍执行原有书目年份核查：与事件年不同且标题无明确事件年时拒绝推断。ML91原始标题没有四位年份，使用精确1991卷键、完整标题、逐篇书目年和官方第8届记录，不从两位标题代码猜世纪。
+
+`1991w`/`1988w`等卷键、booktitle中的Workshops后缀、不同届次/地点/完整标题、未列入的年份均不会获得上述主系列豁免。AISTATS/COLT既有精确规则保留；真正的附属workshop仍受默认不采集workshop的边界约束。
+
+## 原始字段、决定与后续导入
+
+采集器仍保存原始proceedings标题（包括Workshop）、书目年、原始作者名、完整来源书目字段及稳定标识；新增 `track_scope_note` 与官方 `track_scope_evidence_url`。接受状态仍只源自该论文的inproceedings书目证据；不从历史目录生成占位论文或拒稿，也不重新导入已经存在的记录。
+
+新规则的输出必须重新做原始来源/标题/作者/稳定标识与现有库冲突预检，再按增量导入。此前被隔离的ICML1988/1990记录不能仅凭代码规则而直接解除全部冲突。当前正在运行的历史批次使用原固定版本和文件，不能在运行中替换其源码或输入。
+
+## 验证与证据
+
+新增回归覆盖：ICML三届Workshop名称、IROS最初三届、ICML原Conference名称的两届、错误卷键/后缀/标题/未知年份，以及归一化记录经过原生文件导入后保留轨道证据。构建与测试仅在已授权的ces-control远程runner执行，本机仅做语法和文本/JSON一致性检查；结果以相应commit的CI回执为准。

+
+从 ACL 候选中排除上述四卷，原始卷字段和排除理由保留在[候选JSON](historical-source-candidates-2026-11-09.json)的 `excluded_cross_venue_candidates` 中。135个历史会议—年份位置仍未关闭；有初步候选来源的年度由89修正为85，尚未匹配的由46增至50。这些数字是目录初筛结果，不是已验证可导入的论文数。
+
+联合届次仍按具体年度的明确会议身份处理，例如有官方联办证据的卷可以属于多个会议。不能一律排除跨family卷，也不能把联合卷重复导入为两批论文。

+# IJCAI 2018、2022 逐条目录与 track 核查
+
+2026-11-08 的只读生产快照中，edition 867（2018）和 871（2022）已正确属于 IJCAI/ECAI 联办会议，但整本论文集的所有投稿仍归在 `main`。本核查用官方目录的逐条 DOI 和分区定位问题，不修改生产数据。
+
+| 年份 | 库中投稿 | 官方目录条目 | DOI 一对一对应 | 官方 Main track | 明确非 main | 当前目录缺项 |
+| --- | ---: | ---: | ---: | ---: | ---: | ---: |
+| 2018 | 870 | 870 | 870 | 709 | 161 | 0 |
+| 2022 | 863 | 862 | 862 | 678 | 184 | 1 |
+
+2018 官方分区为 Main track 709、Invited Speakers 3、Evolution of the contours of AI 6、Sister Conferences Best Papers 46、Survey track 16、Journal track 24、Early Career 19、Doctoral Consortium 17、Demos 30。
+
+2022 官方分区为 Main Track 678、Special Track on AI, the Arts and Creativity 17、Special Track on AI for Good 33、Sister Conferences Best Papers 26、Survey Track 38、Journal Track 19、Early Career 8、Doctoral Consortium 25、Demo Track 18。Special Track 保留独立范围，不因同在正式论文集就合进 main。
+
+## 862/863 差异已定位，不能删一条凑数
+
+数据库独有条目：`conf/ijcai/Fang22`，题名 **Fixed-Budget Pure Exploration in Multinomial Logit Bandits**，DOI `10.24963/ijcai.2022/409`，页码 2951–2957。submission 333599、source_record 3578445、paper 3442268。
+
+[当前官方总目录](https://ijcai.org/proceedings/2022/) 没有这一条，详情页 `/proceedings/2022/409` 本次 HTTP 404；但[官方论文文件](https://ijcai.org/proceedings/2022/0409.pdf) HEAD 返回 HTTP 200、application/pdf、153657 字节。浏览器读取的官方文件标题、作者 Boli Fang、IJCAI-22 页脚及首页 2951 与数据库对应，共七页。服务器没有下载保存 PDF 正文。
+
+因此这是已定位的“当前 HTML 目录缺项但官方文件仍存在”的来源差异。没有证据证明撤稿、拒稿或数据库多收了一篇；保留原条目与发表证据。其当前官方 track 仍待明确，不根据相邻编号擅自归 main。
+
+## 可复核证据
+
+同目录 JSON 保存两份官方 HTML 的 URL、HTTP 状态、时间、字节数和 SHA256，以及生产只读导出 SHA256。服务器快照目录 `/data/paper-index/collected/ijcai-section-audit-v1/` 保留 HTML、来源回执、原始数据库来源导出和 409 HTTP 回执。
+
+JSON 的 `years[].sections[].records` 每条为 `[submission_id, source_record_id, doi_suffix]`；DOI 为 `10.24963/ijcai.<year>/<doi_suffix>`。这些是现有稳定 ID，不是待插入的新投稿。全部 1732 个当前目录条目均对应唯一数据库来源 DOI，目录与数据库均无重复 DOI，官方目录独有条目为零。
+
+标题仅作辅助核验：NFKC、casefold、去除 Unicode 非 word 字符后，2018 全部一致；2022 有一个拼写差异，DOI `/552` 的 DBLP 标题将 Revisiting、Re-Construction 拼为 Revisting、Re-Constrcution。原始标题均保留，未因此创建或合并论文。
+
+## 未完成事项及修正边界
+
+本次交付只完成来源核查和逐条分区映射，**345 条非 main 的生产分类尚未修正**，第 14 步尚未完成。下一步需要可复用的、带快照前提和验收报告的分区修正流程：
+
+- 保持原 submission、source_record、paper、decision 的 ID 和证据内容；纠正 edition 归属，不制造“新一次投稿”。
+- 同步处理依赖 edition 的 submission_identifiers、覆盖记录与联合会议别名；不能只移动 submissions 一个字段。
+- 保存官方分区文字、URL、源文件 SHA 和原始分类，防止以后 DBLP 整卷刷新把精确 track 覆盖回 main。
+- 对 409 保持单独待核实状态，不推断撤稿、拒稿或当前 main 归属。
+- 修正后独立核验完整投稿/决定历史、稳定标识、各 track 行数及实际查询。研究方法类型不能由 track 自动生成。
+
+这是 2018、2022 两届的完整目录差集和分区证据，不代表其他年份已逐条验收，也不替代所有导入结束后的全库去重。

+# Repairing joint conference membership
+
+EURAI's [official history](https://www.eurai.org/ecai/history) identifies ECAI 2018
+and 2022 as joint IJCAI/ECAI conferences. The pinned DBLP volumes
+`conf/ijcai/2018` and `conf/ijcai/2022` use `IJCAI` as their booktitle and title.
+Existing records can therefore already be present under IJCAI while an ECAI query
+shows a missing year. Adding ECAI as a global alias to the ordinary IJCAI venue
+would incorrectly include all other IJCAI years.
+
+The existing canonical `ECAI+IJCAI` venue has both member aliases. This maintenance
+command changes only the venue reference of the two existing `main` edition rows.
+Edition IDs, submission IDs, decisions, source text, authors, identifiers, tags,
+source links and coverage records stay intact. It does not merge or create papers
+or submissions, resolve per-paper tracks, or turn reviews into negative decisions.
+The DBLP collector applies the joint mapping only to these two exact main volume
+keys; original booktitle/title remain in source metadata with the membership evidence.
+The shared ingestion entry point also resolves these exact pinned source volumes before
+creating an edition, so refreshing an older normalized file cannot recreate a separate
+IJCAI edition. Other sources, years, workshop volumes and additional tracks retain their existing rules.
+
+## Review a read-only plan
+
+Use a runtime containing this repair command. The configured PostgreSQL writer lock
+is used only for the apply operation; do not replace a newer ingestion runtime with
+an older main-based feature branch.
+
+```sh
+PGSERVICEFILE=/etc/paper-atlas/pg_service.conf paper-atlas maintain joint-editions \
+  --pg-service foundry-research --pg-schema research --out joint-plan.json
+```
+
+The preflight requires the existing joint venue and exactly its two member aliases,
+one nonempty unambiguous edition per year, and matching pinned DBLP volume evidence
+for every existing submission. A colliding target edition, missing provenance or
+unexpected source scope fails closed. The plan binds current database/schema, IDs,
+counts and full fingerprints of affected papers, identifiers, source records, tags,
+submissions, decisions and their provenance, and coverage rows. Observation time is
+recorded separately from conference year. These are scoped checks, not a final global
+identity or conference completeness audit.

+# Integrated research runtime
+
+This branch composes the independently reviewed identity guards (PR25), incremental
+coverage (PR27), joint-edition refresh guard (PR29), event identity (PR30), and optional
+annotation support (PR28). It starts from main 1b81d1a and preserves their commits;
+it is an explicit integration dependency, not evidence that those PRs have merged.
+Users merge through Gitea manually. Review this combined diff against main, including
+its conflict resolutions, before using it as the maintained runtime.
+
+The shared Store preserves stable source/identifier anchors before title matching,
+rejects ambiguous unanchored matches, resolves pinned IJCAI/ECAI volumes before event
+lookup, and selects same-year events by event_key. Incremental manifests for a named
+or ambiguous event must state event_key; their parent count and optimistic update
+are checked against that exact event, not the first venue/year/track match.
+
+Query filters compose event_key, status, tags and research type. An earlier rejected
+attempt and a later known acceptance remain distinct; neither annotations nor track
+names infer a research type. Installing this code does not initialize annotation_events.
+Event plans count that optional table when present, alongside the original business
+rows. Annotation initialization and event identity upgrade remain explicit commands
+with their own transactional checks. Neither command imports historical records.
+
+## Production sequencing
+
+1. Verify the exact integrated commit on the approved ces-control runner, including
+   the real PostgreSQL interaction tests and wheel/installed CLI checks.
+2. Stage that exact source in a separate release directory and verify package hashes;
+   leave the current runtime and frozen SQLite backup intact.
+3. Inspect live writers and coordinate through the existing database writer lock.
+   Generate a fresh read-only event plan using that integrated release. Check its
+   database/schema identity, all business counts and preserved history hashes. A plan
+   from before further data or optional-schema changes must not be reused.
+4. Apply only that reviewed file with its actual SHA256, in one transaction. Independently
+   verify the constraint, original edition IDs and fields, assigned Fall source, source
+   and history bytes, ordinary queries, full-text queries and foundry health.
+5. Use the verified integrated release for subsequent writes. Older writers lacking
+   event identity support must not resume against the upgraded schema. Annotation
+   initialization requires a separate explicit operation and acceptance.
+
+These are operational requirements, not claims of completed production deployment.
+The production event-key migration and optional annotation activation have not occurred
+at preparation time. Existing migration/import/repair acceptance remains valid; do not
+rerun those jobs to install source code. Cross-feature tests use disposable fixtures
+and PostgreSQL schemas, never the production research tables.
+
+Coverage output also returns event_key for each independent edition ID. Two same-year
+main events keep their own status/source counts; venue paper totals remain distinct
+work counts rather than sums across events. Legacy datasets without the event column
+return an empty event key and remain read-only compatible.

+# Early WWW archive collector
+
+`paper-atlas collect www-archive` is a maintained metadata adapter. It reads official
+IW3C2 archive HTML, keeps exact source hashes, and separates importable rows from
+program entries that still need review. It fetches no PDF, follows no paper-body or
+reference link, and makes no database connection.
+
+For a fresh source snapshot on the server:
+
+```sh
+paper-atlas collect www-archive \
+  --http-cache /data/paper-index/cache/www-archive \
+  --source-cache /data/paper-index/collected/www-archive-source-v2 \
+  --out /data/paper-index/collected/www-archive-normalized-v2
+```
+
+For reproducible offline replay of the already verified snapshot:
+
+```sh
+paper-atlas collect www-archive \
+  --source-cache /data/paper-index/collected/www-early-archive-source-v1 \
+  --source-cache-sha256 c9388ccef44486e0684c9ee9e8620a465cdc4574e6bc9ea9391d743e01a3312c \
+  --out /data/paper-index/collected/www-archive-normalized-v1
+```
+
+Use a new output directory for another batch. Existing snapshots and normalized
+batches are never overwritten. The manifest hash binds every source URL, byte count,
+response hash and cache filename. Plain files must remain directly within the cache;
+symlinks, escaping paths, duplicate URLs, non-200 responses and altered bytes fail.
+The command uses UTF-8 where valid and explicitly records an ISO-8859-1 fallback for
+older pages; original bytes remain authoritative for encoding corrections.
+
+## Evidence and outputs
+
+- WWW3 Spring 1995 papers use `event_key=www-1995-spring`, `track=main`. The author,
+  session and abstract indexes must have the same nonempty entry-ID set. The ID is
+  local to this exact event and proceedings section, never a DOI or OpenReview ID.
+- Posters remain `track=poster`. An abstract without a linked author-index entry
+  stays in review even when another index has a placeholder `#` link for it.
+- Paper URLs must agree between author and session indexes. A malformed whitespace
+  URL in the abstract list may use the exact event/entry-ID match only when both
+  independent indexes corroborate the same clean URL. The original href is retained.
+- Canonical names come from the explicitly labeled author index. The source lists
+  them alphabetically; this is **not** original byline order. Both the raw index names
+  and the full abstract-page byline/affiliation text remain in metadata. No person ID
+  or cross-source identity is inferred from a name. Conflicting titles or missing
+  abstracts stay in review. Topic keywords are not treated as an abstract.
+- WWW1 1994 formal presentations and WWW2 1994 mixed categories remain review
+  candidates. The first list contains uncertain business-track annotations and a
+  count discrepancy; the second contains panels, tutorials, products and other
+  activities. Neither presentation listing nor a missing full-text link establishes
+  a regular-paper acceptance or a rejection. Raw category/title/name claims are kept.
+
+The main and poster JSONL files have independent manifests with explicit event key,
+track, count and SHA256. `source_listing_count` records the full recognized abstract
+listing, while `held_entry_count` records excluded entries; neither is a ready-row
+count. Their status stays `partial`: a verified linked subset does
+not prove complete event coverage. `review-candidates.jsonl` contains nested
+candidates and reasons, with no importable decision status. It is excluded from
+`import-queue.json`. `report.json` accounts for ready/held records and every source
+used. Newlines delimit JSONL; Unicode U+2028/U+2029 inside metadata are not line breaks.
+The output is published only after all required source and scope checks pass.
+
+## Before importing
+
+This independent collector branch starts from main; it does not include or silently
+install the event-aware writer. Its output requires the reviewed integrated runtime
+from PR31 (or a main revision containing that implementation). The production event
+schema migration has been independently accepted, preserving existing edition1212
+and its 59 Fall submissions; that is not an import of the Spring proceedings.
+
+Inspect held entries and original author names, preflight every ready row against
+current PostgreSQL stable identifiers and candidate identities, and verify the
+source/year/track/event coverage before running `import records`. When a ready subset
+excludes held entries, preserve the independently known listing total in the existing
+incremental-coverage protocol: bind a freshly checked parent count and expected count,
+and set the full expected count from this manifest. A new source uses previous count
+0 and previous expected count null; an existing source requires its actual current
+values. These live parent values are not guessed by the offline collector. Do not automatically
+run this queue against an older writer. Preserve extended versions and independent
+submission/decision evidence, and keep unresolved identities held. A normalization
+report or passing tests alone do not establish production import, complete historical
+coverage or final global deduplication.
+
+Initial fixed-cache replay (64ced7a, CI1057): 38 main papers and38 posters ready;
+372 entries held (50 first-conference fields,307 mixed program entries,15 posters).
+Independent report44dfd070 verified source hashes,counts and author evidence, finding
+one existing exact-title candidate. That publication is explicitly linked to
+arXiv1811.12161 by its WWW1995/journal-reference declaration; arXiv1810.07232 is a
+different1997 invited chapter and remains separate despite the overlap note. This
+is a preparation observation, not evidence of completed production import or final
+global deduplication.
