The persisted projection cache ([RFC](2026-07-27-session-projection-and-command-log.md), shipped as `dsh-session-projection-cache`) surfaced two gaps in the storage substrate it landed on. Both are properties of the domain-KV stack ([design](2026-07-24-domain-kv-storage-and-workspace.md)), not of the cache itself, and both bite the cache first because it is the first *derived* medium on that stack.

**Where the files actually live.** The shipped composition gives the json backend a relative root — `root: './.storages'` (apps/cli/cordis.yml) — and `AppCLIEntry.composePatches` patches only the session store's root to the global harness home (`$DSH_HOME/sessions`, default `~/.dsh/sessions`, profile-overridable via `persistenceRoot`); no equivalent patch or profile key exists for `storage-json`. `JsonStorageBackend` never resolves its root either — each unit open joins the still-relative path against whatever `process.cwd()` is at that moment (packages/storage/storage-json/src/index.ts) — the exact hazard the JSONL session backend resolves-once to prevent ("later process.cwd() changes cannot split one backend across roots", packages/session-persistence/session-persistence-jsonl/src/index.ts). Net effect: session logs are global across launch directories, but `workspace.json` and `session_projcache.json` land under `<launch dir>/.storages/`. Two launches from different directories share their sessions yet see different workspace registries and different projection caches — and the cache exists precisely to serve the cross-session cold listing, which now misses for every session last cached under another launch directory.

**Where the files actually live.** The shipped Web overlay gives the json backend a relative root — `root: './.storages'` (`apps/cli/config/web.cordis.yml`) — while the shared base defaults the session store to the global harness home (`$DSH_HOME/sessions`, default `~/.dsh/sessions`); no equivalent global root exists for `storage-json`. `JsonStorageBackend` never resolves its root either — each unit open joins the still-relative path against whatever `process.cwd()` is at that moment (packages/storage/storage-json/src/index.ts) — the exact hazard the JSONL session backend resolves-once to prevent ("later process.cwd() changes cannot split one backend across roots", packages/session-persistence/session-persistence-jsonl/src/index.ts).

**How recovery works today.** Inside a healthy medium the cache is fully self-healing by design: a `stateVersion`-mismatched row is discarded and refolded, a log shrunk below a row's watermark is detected by the anchored restore floor and answered with one full re-read, and every background write is fail-soft. But at the *medium* level there is no recovery at all: a truncated, hand-edited, or version-bumped `session_projcache.json` fails `openJsonUnit` with `malformed-medium`/`version-mismatch` (packages/storage/storage-json/src/format.ts), a schema-drifted record fails domain open with `invalid-record` (packages/storage/storage-domain/src/index.ts), the rejection propagates through `SessionProjectionCache[Service.init]`, and under the CLI's fail-loud boot the assembly refuses to start. A file whose entire content is rebuildable from session logs can brick boot. This contradicts the cache package's own stated stance ("a stale or unreadable cache costs a longer tail replay, never a wrong value") and the cache domain spec's JSDoc ("version bumps discard the whole medium"), which today describes an aspiration, not the implementation. The same fail-loud path is *correct* for `workspace.json` — workspace records are authoritative, not derivable — so the missing concept is a per-domain declaration of authority, not a global behavior change.

持久投影缓存([RFC](2026-07-27-session-projection-and-command-log.md),已作为 `dsh-session-projection-cache` 落地)暴露了它所依托的存储基座的两个缺口。二者都是 domain-KV 栈([设计](2026-07-24-domain-kv-storage-and-workspace.md))的属性而非缓存自身的问题,且都首先咬到缓存——因为它是这条栈上第一个*派生*介质。

**文件到底存在哪。** 出厂组合给 json 后端的是相对根目录——`root: './.storages'`(apps/cli/cordis.yml)——而 `AppCLIEntry.composePatches` 只把会话存储的根 patch 到全局 harness home(`$DSH_HOME/sessions`,默认 `~/.dsh/sessions`,可经 profile 键 `persistenceRoot` 覆盖);`storage-json` 没有对应的 patch 也没有 profile 键。`JsonStorageBackend` 自己也从不 resolve 根——每次打开 unit 都把仍然相对的路径 join 到当时的 `process.cwd()` 上(packages/storage/storage-json/src/index.ts)——这正是 JSONL 会话后端用「构造时 resolve 一次」防住的那个隐患("later process.cwd() changes cannot split one backend across roots",packages/session-persistence/session-persistence-jsonl/src/index.ts)。净效果:会话日志跨启动目录全局共享,但 `workspace.json` 和 `session_projcache.json` 落在 `<启动目录>/.storages/` 下。从两个不同目录启动,会话相同,工作区注册表和投影缓存却各是一份——而缓存存在的意义恰恰是跨会话冷列表,如今凡是上次在别的启动目录下缓存过的会话全部 miss。

**现在是怎么恢复的。** 在健康介质内部,缓存按设计完全自愈:`stateVersion` 不匹配的行被丢弃重折,日志缩短到行水位以下由带锚的 restore floor 检出并以一次全量重读回答,每次后台写都是 fail-soft。但在*介质*层面完全没有恢复:被截断、被手改或版本被 bump 的 `session_projcache.json` 会让 `openJsonUnit` 以 `malformed-medium`/`version-mismatch` 失败(packages/storage/storage-json/src/format.ts),schema 漂移的记录让域 open 以 `invalid-record` 失败(packages/storage/storage-domain/src/index.ts),拒绝一路穿过 `SessionProjectionCache[Service.init]`,在 CLI 的 fail-loud 启动下整个组装拒绝启动。一个内容完全可从会话日志重建的文件能把启动搞死。这与缓存包自己声明的立场("a stale or unreadable cache costs a longer tail replay, never a wrong value")和缓存域 spec 的 JSDoc("version bumps discard the whole medium")相矛盾——后者今天描述的是愿望而非实现。同一条 fail-loud 路径对 `workspace.json` 却是*正确*的——工作区记录是权威数据,不可派生——所以缺的概念是按域声明权威性,而不是全局改行为。
