Closes #2244. Retrieval matches on concept, and concepts are language-agnostic:
asking about a TypeScript union-find scores 0.72-0.73 against a PYTHON snippet,
comfortably over the 0.68 bar. That is useful — a different-language solution
gives you the shape even when the code isn't reusable — but the menu line said
nothing about it, so the reader either dismissed a good structural reference or
pasted Python into a .ts file.

Worth noting this predates the concept-query change: raw TS code already matched
the Python snippet at 0.73, because the embedder reads identifiers and structure
semantically rather than syntactically. The fail state has been shipping quietly;
#2242 only made it an intended use rather than an accident.

- knowledge._note_to_item projects `language` from the data mirror, same shape as
  the existing verification projection — a plain column read, no body parsing.
- The semantic arm carries language through on the item it builds; it is the arm
  where these arise, since a snippet recorded AT the path you're editing is
  almost never in another language.
- _prior_art_line folds it into the marker: [similar 0.72 · python]. Together
  with the score rather than after the title, because the two jointly are the
  judgement being offered.
- One explanatory line is added to the menu, and only when something on it is
  actually tagged.

Two deliberate calls:

LABEL, DON'T FILTER. A stricter threshold for foreign-language hits would
suppress exactly the shape-borrowing this exists for. They were never the
problem; their being undisclosed was.

ONLY CLAIM A MISMATCH YOU CAN ESTABLISH. _foreign_language returns "" when either
side is unknown — unrecognised extension, or a snippet with no recorded language.
A wrong "· python" is worse than no tag. Same-language hits stay unlabelled, so
the common case keeps a clean line and the preamble stays off the menu entirely.
Operator-typed language names fold through an alias table first (py/python3 →
python, tsx → typescript, c++ → cpp); unrecognised names pass through lowercased,
which still makes an unknown-but-equal pair compare equal.

Trap found while building: _note() in the tests is a MagicMock, so `note.data`
auto-created a truthy mock that would have rendered its repr into a menu line.
Both test helpers now set data = None explicitly.

Implements #2242, from the operator's question: would it make more sense to
search by the concept of the snippet than by the code itself?

It would, measurably. A snippet's embedded text is f"{title}\n{body}", and a
snippet's body is composed markdown — When to use / Signature / Location, then
the fenced code — so `when_to_use` appears TWICE in the vector and the document
is prose-forward. The semantic arm was interrogating it with raw code carrying
no prose at all. Measured on the deployed instance against snippet #2222:

  query built from            score   best unrelated   separation
  raw code body               0.743   0.630            0.11
  name + docstring            0.823   0.602            0.22
  hand-written concept prose  0.835   0.583            0.25

A 12-word description beats a near-verbatim reimplementation of the function,
and code-as-query RAISES the noise floor. It's also the cleanest explanation for
the fragment miss recorded on #2223: a short excerpt carries almost no prose to
match a document that is mostly prose.

So build the query from what the code says it's FOR — declarations plus the
first docstring / JSDoc / leading comment block — shaped as "name(params) — what
it does", mirroring a snippet's own title, which is the form that measured 0.823.

Server-side rather than in the hook: no manifest bump, so installed 0.1.20
plugins get this immediately; multi-language parsing in bash would be miserable;
and it's unit-testable here.

Two rules worth calling out, both measured rather than chosen:

- NO DOC, NO REWRITE. A bare identifier is not a concept and scored 0.671 vs the
  code body's 0.743. Separation from noise is identical either way (0.113), but
  the absolute drops under the 0.68 bar, so preferring a bare name would convert
  a comfortable hit into a miss. Undocumented code keeps the raw payload.
- The 48-char floor still judges the RAW payload, before the rewrite. A concept
  query is allowed to be shorter than the floor — that is the point, the best
  queries are short — but a sub-floor edit stays silent even with a docstring.
  Applying the floor after extraction would discard the best queries.

Regex, not a parser: this is on a PreToolUse critical path and an Edit's
new_string is rarely a valid module, so a miss must cost only a fallback. Every
unrecognised language (Vue SFC, config files) degrades to exactly the previous
behaviour.

Telemetry now logs the concept query rather than the code, since retrieval_logs
is what the threshold gets tuned from and the two aren't comparable.

0.68 is left alone: signal rises to 0.82 while noise FALLS to 0.58, so the bar
sits mid-gap instead of near the edge. To be re-measured against the deployed
instance rather than assumed.

Closes #2223. The write-path prior-art trigger's semantic arm shared
auto-inject's 0.55 threshold, which was tuned on prose. Code embeddings
sit on a much higher similarity floor — any two Python-shaped payloads
share keywords, indentation and structure — so 0.55 landed INSIDE the
noise band. Measured against the live instance:

  near-duplicate of a recorded helper   0.73-0.74   true positive
  unrelated colour math / Vue SFC / CSS 0.55-0.63   false positive
  `x = 1`                               0.58        false positive

6 of 8 probe payloads produced a nudge; 4 were noise. The margin gate
couldn't help — _AUTOINJECT_BAND is relative to the top hit, so with a
single hit it never engages.

Two gates are now the write-path arm's own:

- kb_writepath_threshold, default 0.68 — above every measured false
  positive, still 0.05 below both true positives. Auto-inject keeps
  0.55; it was tuned on prose and is not implicated. The comment this
  replaces explicitly reserved the split for when telemetry showed the
  surfaces wanted different values, so this is the change it described,
  not a reversal of it.
- WRITEPATH_MIN_CODE_CHARS = 48 non-whitespace chars, below which the
  semantic arm doesn't run at all. Whitespace is excluded so a deeply
  indented one-liner can't pass on padding. 48 sits under the smallest
  plausible reusable helper (~60) and well over a degenerate edit, so it
  errs toward keeping recall — precision is the threshold's job. This is
  the cheap half of the operator's #89 idea; the full length<->threshold
  curve stays open there, since they asked to brainstorm it rather than
  have a scale invented for them.

top_k stays shared — "how many titles at once" means the same thing on
both surfaces.

The existing tests were passing `code="x"` / `code="def f(): ..."` into
the semantic arm, i.e. exactly the payloads the floor now drops, so the
gate tests were never exercising a realistic payload. They now use a
REAL_CODE fixture, plus new coverage for the floor (trivial payload,
padding, place-arm unaffected, real helper passes) and a guard on the
constant itself.

Settings UI carries the new knob with the reasoning in its hint, and the
write-path checkbox no longer claims it shares the threshold.

retrieval_logs answers "what did the ranker return, at what scores" — the
right substrate for tuning a threshold. It cannot answer the question the
snippet corpus actually needs: did anyone open this? A snippet nobody
opens is not neutral. It takes a slot in every future auto-inject menu and
crowds out something useful.

Adds note_usage_events (migration 0071): one row per note per event,
either 'surfaced' (we put its title in front of an agent) or 'pulled'
(someone opened it in full), tagged with which surface produced it.

Closes the gap #2082 recorded against this work. The write-path PLACE arm
carries no score, so it has no home in retrieval_logs — folding it in
would corrupt the score distribution that table exists to capture. The
result was that the arm firing on the STRONGEST claim ("there is already a
canonical helper in this exact file") was the one arm nobody could
measure. Both arms now emit usage events under distinct sources, so their
pull-through rates are finally comparable.

Deliberate departures from the task as written:

- Not in-session correlation. The original framing was "correlate
  result_ids against a later get_note in the same session." There is no
  session identity server-side — the MCP endpoint is stateless and the
  hooks send no session id — and adding one would mean threading an
  opaque client-supplied token through every read path. Two independent
  counters answer the question without it: surfaced 40×, pulled 0 is dead
  weight regardless of how those events distribute across sessions.

- Pulls record at the ENTRY POINTS (MCP tools, REST detail route), not in
  snippets_svc.get_snippet, which update and merge also reach. Counting
  those would inflate precisely the number meant to say "someone chose to
  look at this."

- get_note records for every note kind, not just snippets. The auto-inject
  menu surfaces tasks and processes too; scoping this to snippets would
  pin those at zero pulls forever and make them read as dead weight next
  to snippets that merely had a counter.

Surfaced in the Snippets list as an "N/M used" badge, warning-toned once a
record has been offered 3+ times and never opened, with the tooltip saying
what to do about it (usually: its "when to reach for it" doesn't say
when). No badge at all below one surfacing — "0/0" reads as a verdict when
it's an absence of evidence. Also returned from MCP list_snippets so the
agent can see dead weight without opening the UI.

Telemetry keeps the retrieval_telemetry contract throughout: writes are
fire-and-forget, reads degrade to zeroes, and no path can raise into the
surface it observes.

The milestone headline. Auto-inject fires on the operator's prompt; the
moment reuse is actually lost is later, when the agent decides mid-task to
write a helper. A PreToolUse hook on Write|Edit now fires there.

Channel: `additionalContext` with NO permissionDecision, so the note reaches
Claude beside the tool result and the write is never blocked — a recall aid
must not be able to stop the operator's work. Plain stdout would have been
invisible to the model, and deny/ask would have made a nudge into a gate.

Two arms, different in kind:
- BY PLACE — a snippet recorded at this path (or its directory) is prior art
  by definition, not resemblance, so it is neither scored nor thresholded.
  This is what #2083's reverse lookup was built to answer.
- BY MEANING — semantic search restricted to snippets (new `note_type` filter
  on semantic_search_notes) over the code about to be written.
Place ranks first; the top-k cap spans both arms.

Gates carried over from milestone 93 verbatim: threshold, margin, session
dedup, titles-never-bodies. Own `source='write_path'` in retrieval_logs so
precision is tunable separately — the docstring records that the place arm
is unlogged and hands that to #2085.

Its own on/off in Settings but the SAME threshold/top-k: one "how loud may
Scribe be" knob is easier to reason about than two that drift, and splitting
them later is then a data-backed change rather than a guess.

Details worth keeping: the hook sends a REPO-RELATIVE path because that is
how locations are recorded; the git remote resolves to a project and is never
used as the location `repo` filter (different namespaces, would silently
match nothing); the endpoint stays a GET because a read-scoped API key cannot
POST and every other hook depends on that.

plugin.json 0.1.17 -> 0.1.18. Refs #2082, milestone #232.

bvandeusenandClaude Opus 5 8977bed28d feat(inject): label the record kind on each auto-inject menu line
Every injected hit rendered identically, so a recorded snippet was
indistinguishable from a stray dev-log in the one place prior art most
needs to stand out. Each line now carries its kind — [snippet],
[process], [task], [issue], [note] — and the header says "records"
rather than "notes", which it can no longer claim.

Task-ness wins over note_type in the marker: "there's an open issue
about this" is the more useful thing to know at a glance.

Still title-first: the marker is metadata already on the ORM object,
so no extra query and no bodies (#2084).

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.

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).

gates: a per-user confidence threshold (stricter than pull search), a margin
gate, per-session dedup (exclude_ids), and a top-k ceiling. Each retrieval is
logged to retrieval_logs as source=auto_inject so the threshold can be tuned
from data. Per-user config (enable / threshold / top-k) is DB-backed via

#755 Phase 4. Saved Scribe Processes (DRY pass, Drift Audit, …) now surface as
auto-triggered Claude Code skills instead of pull-only get_process calls.

Design correction vs the plan: stubs live in the USER's ~/.claude/skills/, NOT
plugin/skills/_instance/. The plugin is git-cloned and identical per install, so
instance-specific generated files can't ride in it; personal skills are
live-detected within the session (verified via claude-code-guide). MCP prompts
were the alternative but are pull-only (no relevance auto-surface), so skills are
the right primitive.

- backend: GET /api/plugin/processes manifest (services/plugin_context.
  build_process_manifest) — {name, slug, description} per Process; description is
  the auto-surface trigger (title + preview); slugs deduped, blanks skipped.
- plugin: scribe_sync_processes.sh writes ~/.claude/skills/scribe-proc-<slug>/
  SKILL.md (body = "call get_process(name), follow verbatim") and PRUNES stale
  scribe-proc-* stubs. Fail-open + silent; a transient fetch failure never wipes
  existing stubs. Runs as a 2nd SessionStart hook + via the /scribe:sync command.
- plugin.json 0.1.7 → 0.1.8; README updated.
- tests: build_process_manifest (render, slug dedupe, blank-title skip, preview
  truncation). Sync script's write+prune validated in isolation (plugin/** is not
  CI-covered): correct stubs created, stale pruned, unrelated skills untouched.

The SessionStart hook asked for a project_id via plugin userConfig, which pins
one install to a single project — wrong for an operator working across many
repos/projects. Resolve the active project server-side from the working repo's
git remote instead (a stable identifier, not a dir-name guess).

- repo_bindings table (migration 0064) + RepoBinding model: (user, repo_key) ->
  project, FKs CASCADE.
- services/repo_bindings: normalize_repo_key collapses ssh/https/scp/creds/port/
  .git to host/owner/repo; resolve/set/list/delete.
- GET /api/plugin/context takes ?repo=<remote>; unbound repo -> a "bind this
  repo" hint with a ready bind_repo() call. project_id kept as manual override.
- MCP tools: bind_repo / list_repo_bindings / unbind_repo.
- Hook sends ?repo=$(git remote get-url origin) URL-encoded; all project_id
  handling removed. plugin.json drops the project_id userConfig (0.1.2 -> 0.1.3).
- Tests: normalize equivalence classes + unbound-hint rendering.
