[Decision] comment reactions: members cannot react to another user's comment (the author-only update floor refuses it). Store each reaction as the reactor's own record, add one narrow reaction action, or open the floor for the column #22505
Description
Ruled: 6091550406 · letter A amended (reactions column retires; no migration) · 2026-10-10T00:22Z
Filing gate: ② a decision only the maintainer can make. Every fix either loosens a security floor or changes a published storage shape. Filed by the triage seat (seat post #6015, session_01AavokzJ5DndAwitDXvKy4U) from #22500 (measured by the dev of objectstack-ai/hotcrm#2029). Reader: the director seat, to present; then the domain:services seat. ⛔ Not a claim.
Prior rulings read: #4630 (comment authorization, which introduced the author-only update floor); #20558 (a description fix only: reactions is { emoji: userIds[] }, with no ruling on storage or authorization). No ruling on who may write a reaction.
Background (read on main 2e10c9abe0)
-
A reaction is stored on the comment's own row:
sys_comment.reactions, a JSON{ emoji: userIds[] }(plugin-audit/src/objects/sys-comment.object.ts:125). -
The platform's update floor lets only the row's author update a
sys_commentrow. It is deliberate (plugin-security,default-permission-sets.ts, about:1164–:1218, with a moderation alternate). -
objectui's chatter writes a reaction as a PATCH of the whole
reactionscolumn (RecordDetailView.tsx, about:224–:251). -
Measured on 17.7.0 (plugin-security: a member cannot react to another user's comment — reactions are stored on the author's sys_comment row, and the created_by update floor refuses the write (403) #22500):
- a member's reaction on another user's comment → 403;
- the same member's edit of their own comment → 200.
So members can react only to their own comments.
一句话问题
评论的表情回应存在作者那条评论记录里，而平台规定只有作者能改自己的评论。所以普通成员没法给别人的评论点表情。hotcrm 的使用指南写着「可以给评论点表情」。要么改存法，要么开一个口子，要裁的是走哪条。
| 选项 | 做什么 | 客户可感知后果 / 代价 |
|---|---|---|
| A 每个回应一条记录（回应者自己的） | 新增 sys_comment_reaction（评论、表情、用户），归回应者所有；sys_comment.reactions 改为由这些记录汇总的只读字段，或退役（ADR-0087 迁移现有 JSON） |
成员能点、能取消自己的表情；作者专改的底线一字不动；两人同时点不会互相覆盖（现在的整列改写会丢更新）。代价：一个新对象、一次数据迁移、objectui 评论区改读写方式 |
| B 一个窄的「回应」动作 | 服务端提供一个只做「给本人加/去一个表情」的动作，在系统上下文里改作者那条记录；通用 PATCH 仍按底线拒绝 | 成员能点表情；不改数据形状。代价：多一条能写别人记录的特权路径，要单独守住「只能改自己的 id」和「能读这条记录」；整列改写的并发丢更新还在，除非做原子更新 |
C 底线对 reactions 列开例外 |
非作者可以 PATCH 这一列 | 改动最小，但任何成员都能改写别人的回应名单（objectui#11019 那类问题），这是放松安全底线 |
| D 不支持成员回应 | 去掉成员的表情入口，指南改口 | 删一个已发布的能力 |
业务含义直译： A = 每人自己写一张小纸条贴在评论下面；B = 设一个专门的投票箱，只能投自己的票；C = 让大家都能改作者的原稿，只是约定只改表情那一栏；D = 不让大家表态。
四轴分析
os-decision-facets
- ① 项目长远合理性： A 让「谁能写」与「写的是谁的记录」重合，底线不出例外；回应变成可计数、可审计的普通记录，也消掉整列改写的并发问题。B 保留形状，但在底线上开了一条特权写路径。C 直接放松底线。D 倒退。
- ② 实际业务拉动： 实测阻断（plugin-security: a member cannot react to another user's comment — reactions are stored on the author's sys_comment row, and the created_by update floor refuses the write (403) #22500）。一个外部应用（hotcrm）的指南已经承诺这个功能；在仓库内，所有开启了评论的对象都受影响。
- ③ 防 AI 犯错： A 下 AI 写出的应用不需要知道任何例外，按普通的「自己的记录」规则就对。B 要求每个调用方走专用动作，直接 PATCH 仍被拒，容易写错。C 让 AI 以为可以改别人的评论。
- ④ 创业阶段不扩散： B 零件最少（一个动作）；A 多一个对象和一次迁移；C 改动最小，但扩散的是安全面。
推荐 A，回退 B。 ⛔ 不推荐 C（放松安全底线）和 D（删已发布能力）。
- 终态句： 两年后，回应是归回应者所有的普通记录，与 GitHub 和 Slack 的做法同形；评论正文仍然只有作者能改。
- 置信缺口： 现存
reactions数据量未测，生产环境的迁移规模未知；objectui 之外是否还有读这一列的消费方，未全量普查。 - 自检： 只看①选 A；②③④ 是否翻转：否。④ 偏向 B，但 B 的代价是在底线上开特权口子，不是零件数。
裁后执行（维护者只裁方向）
- A ⇒
domain:spec/domain:services：新对象及其权限，reactions列的去向（汇总只读或退役，附 ADR-0087 转换）；- objectui 评论区改为读写回应记录；
- plugin-security: a member cannot react to another user's comment — reactions are stored on the author's sys_comment row, and the created_by update floor refuses the write (403) #22500 由上述 PR 关闭。
- B ⇒
domain:services提供回应动作（只改调用者本人的 id，先校验对评论所在记录的读权限，原子更新）；objectui 点击改走该动作；plugin-security: a member cannot react to another user's comment — reactions are stored on the author's sys_comment row, and the created_by update floor refuses the write (403) #22500 由它关闭。 - C / D ⇒ 照字面执行，并在 plugin-security: a member cannot react to another user's comment — reactions are stored on the author's sys_comment row, and the created_by update floor refuses the write (403) #22500 记录理由。

A, amended — a reaction is the reactor's own record; the
reactionscolumn retires; stored reactions are not migrated. A new objectsys_comment_reaction(the comment, the emoji, the user) is owned by the reactor, so the platform's ordinary rule, a member writes their own records, lets a member add or remove their own reaction on anyone's comment, and the author-only update floor onsys_commentis not touched. Two amendments by the maintainer: (1)sys_comment.reactionsretires outright, with no read-only aggregate in its place: readers (objectui's chatter first) read and count the reaction records; (2) no migration of the storedreactionsJSON: existing reactions are not converted into records and disappear with the column; the changeset states this plainly, and the retirement still carries the retirement discipline's own records (a retired-keys or D3 semantic entry as the field's declaration shape requires), which is governance, not data migration. Concurrency is settled by construction: two members reacting at once write two rows, so the whole-column overwrite that lost updates is gone. ⛔ Not taken: B (a privileged path that writes another user's row, to be guarded by hand at every caller, and the lost-update hazard kept unless made atomic), C (any member may rewrite another's reaction list: a loosened security floor), D (a published capability removed).Execution: the
domain:spec/domain:serviceslanes definesys_comment_reactionand its permission-set rows (create, read, delete-own) and retiresys_comment.reactionson the v18 line (Clause-②: yesfor the new object, the retirement declared); objectui's chatter writes and reads reaction records and stops writing the column (an objectui card, landed with or after the platform side so no window writes a retired column); #22500 closes on those PRs. hotcrm's guide stays true once both land.Prior rulings read: #4630 (comment authorization: the author-only update floor, kept); #20558 (the

session_01VYToj6PQehTEKNrjGM9akg(GitHubos-zhuang; written asobjectstack-fleet[bot]via the relay). The maintainer's amended ruling A (6091550406) retiredsys_comment.reactionsand left open whether a read-only aggregate replaces it; the maintainer then delegated that one point to this seat. Thread-read: 6091550406. Read for this judgment, on objectstackorigin/mainb53b949a15, objectuimainand cloudmain: thesummaryfield type is a scalar roll-up (summaryOperations.functioniscount | sum | min | max | avgover one child field,field.zod.ts:1719–:1747), so it cannot express the{ emoji: userIds[] }map; comments are served through the generic data door (http-dispatcher.ts:1818, objectui'sdataSource.find('sys_comment', …)atRecordDetailView.tsx:1907), with no comment service read path that could attach a computed block; the readers of the column are objectui's chatter only (RecordDetailView.tsx:224–:293,:1885–:1920,:2198–:2218andcollaboration/CommentThread.tsx:25,:592–:593, renderingRecord<string, string[]>); cloud has no reader; the engine's filter grammar carries$in.The judgment
No read-only aggregate.
sys_comment.reactionsretires with nothing in its place on the comment row. The reasons, in the order they decide it:summaryroll-up is scalar), so keeping a{ emoji: userIds[] }column current would take a hook writing the author's row in system context on every reaction insert and delete. That is the privileged write path option B was rejected for, moved behind the scenes, plus a denormalised copy to keep consistent.visiblepredicates readrecord.viewer, a block the service attaches on read, and the shared expression validator refuses all 8 as an undeclared field #22211attachedOnReadshape belongs to a service with its own read path, and the comment feed has none. Adding a read hook that queries a second object on every comment find is new machinery for one UI convenience.find; it adds onefindonsys_comment_reactionwithcomment_id$inthe feed's ids and groups client-side into the sameRecord<string, string[]>shapeCommentThreadalready renders, so the rendering code is unchanged and only the write path moves from "rewrite the column" to "create or delete my own record". One extra batched read per feed load, no N+1.Recorded for later, not built now: if a list view ever needs to sort or filter comments by reaction count, a scalar
summaryfield (countoversys_comment_reaction) is the declared, engine-maintained way to add it, on a named need.Prior rulings read: 6091550406 (this card, A amended); ADR-0049; ADR-0056; #22211 A 6070963704 (
