bvandeusen	ef1dbdfc86	feat(acl): unify the retrieval scopes; mark shared rows in Knowledge browse ... Closes #2092 and the Knowledge-browse provenance gap. The two halves of a hybrid search disagreed: the keyword half honoured shares while the semantic half was pinned to NoteEmbedding.user_id, so a shared record was findable by wording and invisible by meaning — the case a semantic search exists to serve. semantic_search_notes now scopes on Note via a `scope` parameter, and each of its five callers declares which kind of act it is: mcp/tools/search.py read the agent asked routes/search.py read the user typed it knowledge.py (semantic) read matches the keyword half beside it plugin_context.py browse nobody asked; never a one-to-one share dedup.py own a verdict that blocks a write must not hinge on another person's notes That last one is the reason this isn't a single global widening: the dedup gate returns "update the existing one instead", so matching a stranger's record would refuse a legitimate create and point at something the caller can't edit. Scope defaults to "own" so a caller that forgets is wrong in the safe direction, and an unknown scope raises rather than falling back — a typo there would be a data-exposure bug. Auto-inject keeps the browse scope, which still admits a collaborator's note via a shared project. Its menu line is the only provenance an agent sees, so a foreign hit now reads: #12 "Title" (0.71) - shared by alex, treat as a suggestion. MCP and REST search results carry shared/owner too. Knowledge browse: the feed hydrates cards from /api/knowledge/batch rather than the list route, so both paths label rows now, and KnowledgeView shows "by <owner>" on records the viewer doesn't own.

bvandeusen	8b069cc93f	fix(acl): make the visibility predicates pure builders; repair CI ... Run 2888 failed with 7 tests down, both causes mine. The real problem was a design flaw, not the tests: readable_notes_clause and browsable_notes_clause each opened their own DB session to fetch the caller's group ids. That made them unmockable at the call site, so every unrelated service test suddenly had to know they existed and stub them — four modules broke the moment a service started calling one, and one of my own stubs patched the wrong name (readable_* where the code had moved to browsable_*). Fixed at the root: group membership is now a SUBQUERY rather than a fetched list, so both clauses are synchronous pure functions with no session. One fewer round-trip per query, membership folded into the statement the caller was already running, and nothing for callers' tests to mock. The "no groups means no group arm" special case disappears too — an empty subquery simply matches nothing. Also: _fake_note in the process tool tests had no real user_id, so its auto-MagicMock attribute reached session.get(User, ...) through the new provenance check and SQLAlchemy rejected it. The fixture now takes a real user_id defaulting to the bound caller, which makes "is this shared?" meaningful, and gains a case asserting another user's process comes back flagged. Test assertions on compiled SQL are deliberately loose about formatting: the local env has no SQLAlchemy (rule #10), so they check that the arms exist rather than guessing at exact rendering.

bvandeusen	04b58ce01e	feat(acl): shared records are search-only and always labelled as someone else's ... Narrows the b7d6fc7 widening per the operator's call, and fixes a regression it introduced. Decision recorded as note 2094. Two scopes now, deliberately different: readable_notes_clause — everything the ACL permits, including records reached only via a direct/group note share. For EXPLICIT acts: a search the caller typed, a fetch by id. browsable_notes_clause — the caller's own records plus anything in a project they can reach. For PASSIVE surfaces: browse lists, facet counts, the process->skill manifest. The split is a trust boundary. Anything appearing unasked — in your own list, your own counts, or as a skill installed on your machine — reads as material you endorsed. A one-off someone shared with you hasn't earned that standing, so it waits until you go looking. This also dissolves the shared-Process problem by construction rather than by special case: the manifest is a passive surface, so a directly-shared Process is never installed as an auto-surfacing skill. Regression fix (#2093): b7d6fc7 widened the list queries but left the fetch path owner-only, so on the MCP path a record could be listed and then not opened — get_snippet raised not-found, get_process couldn't resolve, and the manifest emitted stubs whose get_process call would fail. snippets.get_snippet and notes.resolve_process now resolve the read scope. delete_snippet gained an explicit can_write_note guard, since being able to SEE a shared snippet must not imply being able to bin it. Provenance, so nothing arrives looking like the operator's own work: - access.describe_provenance / label_shared_items add shared/owner/permission; labelling costs no query when everything is the caller's own. - MCP: get_snippet, list_snippets, get_process and list_processes carry it, and get_process now says outright NOT to follow a shared process verbatim — its follow-as-written contract was the sharpest instance of the problem. - The skill stub for a shared Process names its author and asks for a go-ahead, instead of describing it as "the operator's saved Scribe process". - Policy stated once in the MCP _INSTRUCTIONS and the reusing-code skill: a shared record is that person's suggestion, weigh it, attribute it, ask before adopting it. - UI: shared snippets show "by <owner>" in the list and a notice above the code in the detail view, reusing SharedWithMeView's vocabulary. Plugin 0.1.15 -> 0.1.16 (skill text changed).

bvandeusen	b7d6fc7e5d	fix(acl): make shared records findable, not just openable (#2079) ... Option A of the #2079 fork, per the operator's call: widen the scope in query_knowledge for every caller rather than special-casing the snippet path. Until now the list/search queries filtered on Note.user_id alone, while get_note_permission resolved shares properly. The result: a record shared with you could be OPENED by id but never FOUND — invisible in Knowledge browse, in snippet and process lists, and in the facet counts beside them. - services/access.py gains readable_notes_clause(user_id): the same resolution get_note_permission does per row (ownership, direct share, group share, inherited project share), expressed as set membership so a list query can use it in one statement instead of O(n) permission round-trips. - services/knowledge.py routes every query through it — query_knowledge, the keyword half of the hybrid search, query_knowledge_ids, get_knowledge_by_ids, get_knowledge_tags and get_knowledge_counts. The facets follow the list, or a tag visible in the list would filter it down to nothing. - list items now carry user_id, since these lists can be mixed-ownership and the client has no other way to mark what isn't yours. Reaches four surfaces: the Snippets list (the original report), Knowledge browse, list_processes, and the plugin's process manifest — so a Process shared with you now also syncs as a local skill stub, which is the point of sharing one. NOT widened: semantic_search_notes, which scopes by NoteEmbedding.user_id and also backs auto-inject and the search MCP tool. Widening it would put another user's content into your agent context automatically — a product decision, not a bug fix. Consequence until that call is made, marked at the call site: a shared record is findable by wording but not by meaning.
