 latency where it plausibly buys recall quality. `mode: "always"` restores
 unconditional pre-reply recall; `mode: "off"` disables the lane.
 
+## Project-scoped memory
+
+Repository work adds a second retrieval boundary alongside provenance. When a
+turn runs inside a Git repository, memory written by that work carries a
+trailing project annotation:
+
+```markdown
+- Use the release helper for package validation. <!-- project: github.com/openclaw/openclaw -->
+```
+
+The identity comes from the normalized `origin` remote, so ordinary clones and
+linked worktrees of the same repository converge on one key. Forks intentionally
+remain separate because their remotes name different repositories. A repository
+without an `origin` uses its absolute root path instead. The resolved identity is
+cached for the process lifetime; semicolons are escaped so one key cannot become
+multiple list entries, and recall never starts Git once per message.
+
+Project scope changes ranking and automatic injection without partitioning the
+files. Ranked search boosts entries from the active repository, mildly demotes
+entries from another repository, and leaves untagged memory neutral. Trigger
+injection is stricter: a tagged entry is eligible only while its repository is
+active. Each full turn also gets a compact, separately budgeted project-memory
+block built from curated entries for that repository. `USER.md` and standing
+intents remain user-level and are never project-scoped.
+
+This matters most for a many-repository worker: a build workaround learned in
+one codebase should not silently steer work in another. In one continuous
+repository session, the annotation is mostly invisible; ranking and bootstrap
+refresh preserve the same learned context across compaction and dreaming. A
+session that moves to another repository updates its active identity on the next
+turn, and a sub-agent derives its own identity rather than inheriting its
+parent's. Sessions outside repositories retain the previous global behavior.
+
+The boundary follows the same research result as the rest of recall: selective,
+query-relevant context outperforms indiscriminate history as sessions and
+corpora grow (LongMemEval, arXiv:2410.10813). Project identity is therefore a
+deterministic eligibility and ranking signal, not another model judgment or a
+new configuration surface.
+
 ## The user model
 
 `USER.md` is a separate curated file for the user model: stable
