feat(inject): 能力说明 + 约束/偏好分池逐字保真(issue #249 第一批) - #266
Conversation
- 新键 injectGuidanceEnabled(默认关):memory_search / memory_save 工具描述 尾部追加判断指引,并注册 order 150 系统提示段(常量文本、同会话稳定); 指引写英文单一正本(src/guide.js),与 memory.language 管辖的生成内容/块内 标题分家 - 新键 pinnedInjectBudget(0-5,默认 0 = 关闭):约束/偏好类进独立 pin 池, 块头前置、不参与跨轮轮换(也不进轮换历史)、逐字保真(2000 字硬顶,超顶 照旧带截断提示),超预算条数在块内如实标注「另有 N 条未展示」 - 默认档注入块构成逐字节不变(回归首例锁这条);选路统计经可选出参 pinnedStats 透出,injectCandidates 的数组契约不变 - 测试 1220 -> 1228

memory conflicts with current instructions or repository state, it directs the
reader to inspect those current sources before relying on memory; reserve
memory_search for cases where earlier context is needed, while retaining the
warning against treating old memory as current fact. Apply the same wording to
the guide definitions in both source and generated files.
In `@dsh-mneme/src/inject.js`:
- Around line 219-221: Update the budget handling around the pinned check in the
injection loop: when processing a pinned entry, append the full content without
decrementing the shared budget; for non-pinned entries, retain the existing
budget check, decrementing only when full content is accepted and otherwise
using the title-only form.

- 块渲染:pin 条目原先照扣共享 budget,而 PINNED_CONTENT_MAX(2000) > MAX_BLOCK(1500), 一条 pin 就够把 budget 压成负数,同一轮随后的普通候选全部退化成标题行——与本函数 「pin 池不参与块的塌缩预算」的设计注释相反。改为 else-if,pin 只进不出预算。 - guide:优先序那条原写「与指令/仓库冲突时用 memory_search 求证」,但 memory_search 只搜记忆库、读不到当前指令与仓库状态;改为先读指令/仓库本身,工具描述同步改成 「找更新的记忆」。 - 回归:新增「pin 不吃普通候选预算」(1880 字 pin + 普通条目仍带完整正文)与 guide 文案断言。

审阅通过,0 回归(1160 绿,15 个 fail 是环境相关的既有问题)。两个小问题留作后续:
src/service.js:1496「未展示 N 条」把进 general 槽的也算进未展示,计数虚高(PR 自己的超预算测试里展示了 pref#2 仍报"另有 2 条未展示")。src/inject.js:158降级行的「逐字保真」不成立:_full_content短路后返回m.content(有损摘要)且无上限,绕过PINNED_CONTENT_MAX。
不影响合并。
评审(Anans-Ivresse)指出两处——不影响合并,但都是真缺陷: - 「另有 N 条未展示」按 eligible - pinned 直接相减,把被 pin 预算挤下来、却仍被 general 槽选中(即真的在块内)的条目也算成未展示。改成统一按「有没有进 selected」 判:suppressed = eligible 里没进块的条数(评审实测:pref#2 已在块内仍报 2 条)。 suppressed 因此挪到 general 选完之后算,eligible 提到块外留一手。 - injectMemory 的 `_full_content` 早返回唯一效果就是跳过 maxLength(两条分支取的都是 m.content,差别只在截不截),于是 pin 的 PINNED_CONTENT_MAX 在这一路形同不存在。 删掉该分支,只留一条截断路径:超限照旧带提示,原文永远可 memory_get 取回。 语义边界(避免「逐字保真」被过度承诺):对已被 sleep 降级的行,注入的是该行当前正文 (即其摘要)——降级是 sleep 的审计决定,注入层不擅自复原 _full_content;本次修的是 「它不该因此绕过上限」。 测试:两条既有断言正好把旧行为写成了契约,一并改成新契约(旧断言即新测试的反证): inject-content-cap 的「400 字符摘要不加提示」→「照截 + 带提示」;inject-pools 的超预算 用例 →「另有 1 条未展示」并断言被挤下的那条真的在块内。 验证:注入相关三文件 32/32;全量 1229 tests / 1228 pass / 0 fail / 1 skipped; check-sync 43 文件一致;所碰文件 lint 无告警。

PR 描述草稿 —— issue #249 第一批
范围
issue #249 的第一批两件事:能力说明 与 B1 约束/偏好分池逐字保真。两个新键都默认关/零:
injectGuidanceEnabledfalsepinnedInjectBudget0(关闭)默认档下注入块与改动前逐字节一致(回归测试第一例锁这条)。分时机注入(N2/N3)与注入可观测性/面板按排期归 #179 与后续批次,本 PR 不碰。
能力说明
memory_search/memory_save追加判断指引。判据是「何时不该用」在现描述里有没有歧义:memory_list/memory_get/memory_update的触发是机械的;memory_register_document([Feature] document 型记忆:agent 产出的长文档入库——注册校验、摘要+指针落库、supersede 记账 #230 已内建Use for … lookups)与memory_runtime(已自带 provision 成本告诫)不重复。memory_delete的描述只有一句"Permanently delete a memory entry.",没有不可逆与可逆替代品的指引——这是全部指引里唯一有数据损失后果的缺口。它属跨工具判断,所以进总则第 5 条(memory_archive/memory_forget可恢复,memory_delete永久),不塞进某个工具描述。src/guide.js),不做 zh/en 双写。理由:注入指引的参照实现(ACP 的ACP_SYSTEM_PROMPT+HOW_TO_COMPRESS_RULES、mnemon 的ROUTING_GUIDANCE、宿主压缩摘要规则)全为英文,仓库既有先例也是工具描述硬编码英文;而memory.language管的是生成出来的记忆内容与块内标题,与本模块是两件事。这是对config.language的一次有意偏离——若你认为该跟language走,改成双语很容易。pin 池
maxInjectedItems名额、也不被documentInjectBudget截断——独立预算的意义正是不让 pin 反向触发「批量塞历史」。injectContentMaxChars的常规截断,只受Math.max(injectContentMaxChars, 2000)的硬顶(超顶照旧带截断提示)。逐字不等于无界——一条超长约束若无上限,会每轮把常驻段吃满。STR.pinnedOverflow,走memory.language,与块内其他文案一致)。pinnedStats透出,injectCandidates的「返回数组」契约不变(约 20 处调用方与测试不受影响)。验证
1228 tests / 1227 pass / 0 fail / 1 skipped(基线 1220 + 新增 8,零回归;skipped 为既有项)test/inject-pools.test.js8 例,逐条对应 §11 验收:默认档零变化 / pin 前置且不占名额 / 超预算如实标注 / 轮换豁免 / 逐字保真 / 硬顶仍带提示 / 能力说明只注册一段且不逐轮复读 / 只动两个工具描述且为尾部追加check-sync:src ↔ lib 43 文件一致;所改文件 lint 无告警待你拍板(这三处都没自行决定)
constraint与codingGate:constraint同属CODING_MEMORY_TYPES,非编码任务里已被src/service.js:1326的codingGate滤掉,pin 池同样拿不到它。本批次不改既有门控;要豁免的话是一行条件,等你的口径。Math.max(injectContentMaxChars, 2000)。autoInject的口径冲突——autoInject已默认true,且是src/index.js:464决定挂不挂注入器的总闸;按稿把它改成「父默认关」,升级即对全体用户关掉注入,属破坏性变更,所以没动。请求一遍复核
这套指引是从议题 §5 的样例与三条参照实现推出来的,担心存在局部过拟合。想请你换角度复核一遍——措辞、遗漏的判断、是否该更短或更硬,特别是总则第 5 条与两个工具描述的追加句:它们会常驻在每个会话的提示里。
