A snippet had no field for prose, so what a session learned about one went
into when_to_use — the trigger joined onto every chunk it is embedded as. A
sweep found write-ups of up to 3 KB there, headings and all.

- notes: stored after the code under `## Notes`, parsed back from the body,
  carried by every path that rebuilds it (update, merge, un-merge). A
  snippet with no notes composes the body it always did.
- create/update_snippet (MCP) take notes and return trigger_advice when
  when_to_use is long, headed or multi-paragraph. Advice, not a refusal.
- Tool docs, the reusing-code skill and the editor hint describe the trigger
  as the situation and point the explanation at notes.
- Editor gains a Notes field; the detail view renders it as markdown.

bvandeusenandClaude Opus 5.5 66e21a6c60 refactor(notes): a snippet's and lesson's stored title is its name; the trigger joins it only in the embedded document (milestone 427)

The title was `subject — trigger` because the stored title WAS the
embedded one, and the join is what makes these kinds rank on the
situation they apply to (#2485). Every surface that shows a title then
showed the trigger too -- menus, lists and search rows ran to kilobytes.

- embeddings.document_title(title, note_type, data, body) joins the
  trigger from `data` (body fallback) at embed time. Idempotent: an
  un-migrated composed title comes out the same, never doubled. The
  embed path, the startup backfill and the dedup gate's semantic signal
  all use it, so the embedded text -- and every vector -- is unchanged.
- Writers store the subject: snippet create/update (service, REST, MCP)
  and lesson_document. Both compose_title helpers are removed.
- Readers: dedup takes `data`; the menus strip the embedded title from a
  passage; list rows project `when_to_use`, which SnippetListView reads.
- 0108 rewrites existing rows on an exact `' — ' || <own trigger>`
  suffix with raw SQL, leaving updated_at alone so the backfill does not
  re-embed the corpus for identical vectors. Downgrade recomposes.

`usage_for_notes` is named for notes and works on every note row, yet the chip
reached snippets and rules only. Notes had it nowhere. Lessons had it collected
and shown nowhere a person could reach, because #4196 taught `/api/lessons` to
attach it and `KnowledgeView` — the only lesson list in the UI — browses through
`/api/knowledge`, so `listLessons` still has no consumer.

The cause was not a missing line. SEVEN call sites carried their own copy of the
same few lines: two REST lists, two REST details, two MCP lists, one MCP detail.
Each read perfectly well alone, so "which doors attach usage?" had no answer
anywhere in the code — the same asymmetry test_system_tagging_door_parity.py
records for System tagging (#4249), where whichever door nobody exercised for a
kind is the one that never grew the feature.

`attach_usage(rows, key="id")` is now that answer, and all seven go through it.
A detail payload is a one-row list, so the single-record doors share the seam
rather than keeping a second shape beside it. Deliberately NO try/except: the
fail-open already lives in `usage_for_notes`, which reports through
`_report_failure("readout")` and returns the zero-filled map. Wrapping it again
would swallow the REPORT as well as the error, and a silently-swallowed readout
failure is exactly #2663 — every counter reading zero in production for weeks
while the writes landed fine.

`/api/knowledge` now attaches usage, which closes both holes at once: it is how
notes, lessons and processes are all browsed. `KnowledgeView` renders the badge
on the card footer, looking the advice up per row because the feed is mixed.

The advice moves to utils/deadWeight.ts. Canon #3460 says each caller owns its
own const, and that held while each caller showed ONE kind; a mixed feed would
need five of its own and the next surface another five. The canon's actual
invariant — advice is kind-specific and never baked into the badge — is kept:
it is still a prop. The three existing callers now read the same table, so the
sentence has one home rather than four. Recorded against #3460 so the next
reader is not left re-litigating it.

`_row_id` rejects bools explicitly: `int(True)` is 1, so a row carrying a flag
under the key would be credited with note #1's counts, and a wrong chip is worse
than no chip because it reads as a measurement. A row with no usable id is
skipped rather than failing the page.

Tests pin the PROPERTY, not one route: no door calls the aggregate directly
(AST, so a comment naming it is not a false positive), and every door that shows
usage reaches the seam. Plus the N+1 guard — one aggregate per page, asserted on
await_count, because the per-row version reads more naturally and is invisible
in review.

`set_record_systems` is not a dumb setter. It runs its own `can_write_note`
and then links only the Systems the given user can READ. Four of twenty
call sites handed it the record's owner instead of the acting user, which
did two quiet things at once: the access check became trivially true, since
an owner can always write their own record, and the System filter used the
owner's visibility rather than the actor's.

On a single-user install neither is observable. With a share it is an
editor acting with the owner's reach — the shape rule 47 exists to prevent,
and the same reasoning routes/notes.py already spells out for
`set_supersedes` two lines away.

This is NOT a permission change. Every one of the four sites establishes
the caller's write access first: routes/lessons.py and routes/snippets.py
call `can_write_note(uid, …)`, mcp/tools/processes.py does the same, and
mcp/tools/snippets.py reaches `set_record_systems` only after
`update_snippet` has raised PermissionError if the caller may not write. So
nobody gains or loses the ability to edit anything. What changes is whose
reach the tagging runs with, which is exactly the kind of difference that
survives review because every call site reads fine on its own.

The four:

  routes/lessons.py:243      owner_uid      -> uid
  routes/snippets.py:211     owner_uid      -> uid
  mcp/tools/snippets.py:486  note.user_id   -> uid
  mcp/tools/processes.py:196 note.user_id   -> uid

The last one was written earlier in this same session, an hour before the
sweep that found it, with a comment confidently explaining why the owner
was correct. That is the argument for the guard rather than for care: the
unified stance was known and still got it wrong at the next opportunity.

So the guard is the point again. `test_every_tagging_write_acts_as_the_caller`
walks every `set_record_systems` call in src/ and asserts the first argument
is a bare local named `uid` or `user_id` — an attribute access is a record's
owner by construction. Verified against `git show HEAD:` as well as the
working tree: clean now, four offenders on the code it replaces.

Reads are deliberately untouched. `list_record_systems(owner_uid, …)` gates
on reading the NOTE, which the caller can do anyway, so it returns the same
list either way; it is a different operation and churning it would add noise
without changing behaviour.

First consumer of the forge adapter. attach_live_body decorates both
pull surfaces (MCP get_snippet, REST detail) with body_source +
body_freshness when the instance has a forge: 'current' means the
cached code was just found verbatim (whitespace-normalized, the same
normalization the verdict hash uses) in the fetched file, and
provenance restamps to the file's last commit — reflected in the
response and persisted in the background. A snippet body is a FRAGMENT
of its file, so a fetch can honestly CONFIRM the cache or report
divergence, never clobber the record with the whole file: 'diverged'
is the reader's information, and a 404 stamps the mechanically-true
'missing' verdict into the existing attention state — once, not on
every pull of an already-flagged record.

The probe never raises and never blocks past 2.5s (tighter than the
adapter's own timeout — the pull is where a session decides whether
pulling is worth it, #2663's finding); a hung forge costs bounded time
and the cache serves. A no-forge instance's response stays
byte-identical to today's (rule #115 baseline, pinned by test).

services/background.py is the new one home for fire-and-forget tasks
with strong references (the #2663 GC footgun) — telemetry's two copies
predate it and keep their bespoke canaries; new callers use this.

The snippet gate was reading the wrong field, and #2464's UI recipes made it
measurable in both directions at once:

  .btn-danger vs .btn-danger-outline   0.92   siblings, BLOCKED
  .btn-primary re-recorded verbatim
  under a different name              <0.90   a literal copy, ALLOWED

The second is what settles it. Identical code at an identical repo·path·symbol
sailed through because the description differed, while two deliberately
parallel variants were refused because theirs did not. A snippet's embedded
document is mostly prose ABOUT the code, so no threshold fixes this: lowering
it blocks more siblings, raising it admits more copies.

So structure decides. Two exact signals, both index-served off the notes.data
mirror that already exists, no migration and no backfill:

  location  the same named thing in the same file. Requires BOTH path and
            symbol — a path alone is a directory of artefacts, and matching on
            it would refuse every second recipe from one stylesheet.
  code      byte-identical code anywhere, via the same fingerprint the drift
            check uses.

The semantic arm survives as a backstop for a genuine reword that shares
neither, raised to 0.96 so it sits above the 0.92 band where real variants
live. Structural hits say what they matched instead of hedging with "similar",
and point at merge rather than update — two records of one artefact is what
merge exists to fold back together.

find_duplicate_snippets gets the same correction: pairs where both snippets
name a symbol, name DIFFERENT symbols, and hold different code are variants,
not copies. Without it a design system's button family reports as one merge
set — eight recipes, every direct pair over the floor, top score 0.92, one
click from collapsing a component family. The cost is real and stated in the
code: a helper recorded twice under two names no longer reports. That trade
favours the report being usable, and same-symbol and unnamed duplicates — how
re-recording usually looks — still surface. The filter fails open, so a lookup
failure degrades to the old unfiltered report rather than to a reassuring
empty one.

resolve_locations extracted: compose_body, create_snippet and now the gate each
had their own copy of the repo/path/symbol shorthand fallback, and the gate is
the one where a disagreement would mean matching a location the record won't be
stored with. Applied to both create surfaces (#33) — the web UI must not be the
way to record what the agent was stopped from writing.

CI & Build / Build & push image (push) Successful in 40s
Closes the last of milestone #232. The task said to settle the design
before coding; here is what was settled and why.

THE HAZARD. Restoring a merged-in source from the trash brought the record
back but never stripped its locations off the survivor, so both claimed
the same call sites and the reverse lookup read the duplicate claims as
real. Subtracting blindly is not a fix: a location can arrive from a
source AND genuinely be the survivor's own, and _normalize_locations dedups
them into one, so blind subtraction would strip a call site the survivor
owns. Same problem defeated partial un-merge — `merged_from` recorded ids,
not which locations came from which source.

THE ANSWER. Record per-source attribution AT MERGE TIME, where it is known
exactly: each entry keeps only what that source ADDED, computed
incrementally as sources fold in. Anything the survivor already had, or an
earlier source already brought, is attributed to nobody. Both open
questions fall out of that one change — partial un-merge is exact, and a
survivor-owned location can never be stripped, because it was never
attributed in the first place.

The shape moved from [id] to [{id, locations, tags}]. Free to do: the
corpus holds one snippet and zero merges, so there is no legacy data (rule
#22). A bare int still normalizes to {"id": n} — not legacy tolerance, but
because snippet_fields falls back to PARSING THE BODY when a row has no
`data`, and the body's provenance line can only carry ids. Such an entry
shows history and refuses un-merge with a reason rather than guessing.

WHICH SURFACE. Neither option in the task, quite. Making trash-restore
notice the merge would teach the generic trash path snippet semantics for
one record type. Instead un-merge OWNS the restore: one operation, one
authorization check, trash stays ignorant. Restoring by hand is still
allowed and still leaves both records claiming the same places — so
un-merge treats an already-alive source as the normal case and goes
straight to the subtraction that repairs it. That is the state that
motivated the feature, not an error.

Adds trash.restore_entity(user_id, type, id) — the missing inverse of
delete(), which returns a batch id callers don't keep. Restores the whole
batch, since the batch is the entity plus its cascade.

#231's premise was unifying reusable things already scattered as one-offs.
The create gate PREVENTS a new duplicate and merge_snippets CURES one you
point it at, but nothing FOUND the duplicates already in the record —
someone had to notice them by hand, which is the exact failure the Drafter
exists to remove.

One indexed self-join over note_embeddings, not an N² Python scan:
pgvector's cosine distance is the same operator semantic search uses, so a
similarity floor is a distance ceiling and the work stays in Postgres.
`left.note_id < right.note_id` yields each unordered pair once and drops
the self-pair that would otherwise dominate the ranking.

Pairs are collapsed into merge SETS by connected components. Transitive on
purpose: A~B plus B~C puts all three together even when A and C don't
directly clear the bar, which is what merge actually does (it folds every
source into one survivor). The cost is that a chain of mild resemblances
can rope in a member that isn't really alike — so the UI presents a set as
a proposal, shows the members, and never merges without a confirm.

Two scope decisions worth naming:

- OWN snippets only. merge_snippets requires one owner across the set, so
  surfacing someone else's would propose a merge that cannot be performed.
  The report is bounded by what the operator can act on, not what they can
  see.

- Threshold defaults to 0.82, LOOSER than the write gate's 0.90, and is a
  setting rather than a constant (rule #25). The gate blocks a create and
  has to be unforgiving of noise; this only suggests a merge under review,
  so it must reach further or it would never surface the pairs the gate
  already let through — which are precisely the ones that accumulated.

Fixes a real bug in the merge flow while wiring the UI: selectedList
filtered the selection against the CURRENT PAGE, and doMerge derives its
source ids from that list. A corpus-wide suggested group with off-page
members would have rendered incomplete and silently merged only the
visible subset. A group under review is now the authority for that list.

A recorded snippet points at a repo · path · symbol that WILL rot: files
move, symbols get renamed, implementations diverge from the copy stored
here. Nothing detected any of it, so a record degraded silently from
"canonical reference" to "confidently wrong" — worse than no record, since
it is surfaced with the same authority either way.

WHERE THE CHECK RUNS. Agent-side, which the task flagged as the design
question to settle first. Scribe has no checkout of the operator's repos
and must not acquire one: giving the server repo access would make every
install a credential problem and break instance-agnosticism (rule #115).
The agent already has the working tree, so it does the comparing; the
server remembers the verdict, makes it queryable, and knows when it has
expired. New MCP tool verify_snippet teaches the four-step procedure and
records the result; a REST endpoint mirrors it so the UI can clear a
marker after a manual fix.

WHY THE VERDICT CARRIES A CODE HASH. A verdict describes the code it was
checked against. Invalidating it on edit means deciding which edits count
— a when_to_use tweak shouldn't void a code check, a rewrite must — which
is fiddly and easy to get subtly wrong, and easy for a new write path to
forget entirely. Stamping the verdict with a hash sidesteps all of it: one
whose code_sha no longer matches is self-evidently expired, computed at
read time, no invalidation branch to maintain.

That makes "expired" the interesting filter case. It is not `drifted`
(nothing was found wrong) and not `unverified` (a check did happen), yet
it plainly needs looking at — so `verification=attention` covers both. To
keep that one index-served predicate rather than a post-filter that would
make the pagination total a lie, data now also mirrors the CURRENT code's
fingerprint as data.code_sha, and a jsonpath compares the two fields
within the row. The filter is implemented in both dialects, SQL and
Python, for the same reason the location filter is: the semantic arm's
candidates arrive already fetched.

A merge deliberately carries no verdict forward — the survivor's code is a
union of several sources, so no prior check describes it, and unverified
is the honest answer.

UI: a danger-toned drift badge on each card (an actively misleading record
outranks a merely unused one), and a "Needs attention" filter. Its empty
state says plainly that never-verified snippets don't appear there —
otherwise `attention` would mean "everything" on day one and be useless as
a worklist.

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.

"What canonical helpers already live in this file?" was unanswerable:
location lived only in the body markdown. It is now a jsonpath containment
query over the `notes.data` mirror added by migration 0070.

- One predicate in two dialects in services/knowledge.py: SQL (`data @?`,
  applied in the browse arm and the keyword arm before count/pagination, so
  totals stay honest) and Python (`location_matches`, for the semantic arm
  which post-filters candidates it already holds). Both must change together.
- Parts are ANDed within a SINGLE locations entry — repo A in one entry and
  path B in another is not "recorded at A/B". `path` also matches as a
  directory prefix, via jsonpath `starts with` rather than `@>`, which the
  same GIN index serves.
- `repo`/`path`/`symbol` reach the service, the REST list and the MCP tool
  under one name with one default (rule #33); the MCP docstring teaches the
  place form, and so does the reusing-code skill (plugin.json bumped).
- UI: a Location disclosure beside the snippet search, with its own empty
  state — "nothing kept there, so what you're about to write is new."

Settles #2083's open question (pre-0070 NULL `data`) by backfilling after
all: `backfill_snippet_data` runs at startup, deriving the mirror from the
body with the same parser the read path trusts. 0070's caution was about
mangling a hand-edited body; this never touches the body. The alternative
was a permanent second body-regex arm, or a query that silently answers
"nothing here" for an old snippet and gets the helper written twice.

  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).

Four defects from the 2026-07-25 review of the recall (#227) and merge (#231)
milestones. The theme: a snippet could be recorded but not fully corrected, and
the agent and web surfaces had drifted apart.

- #2076 language was mis-derived from the first caller tag, so a snippet created
  with tags and no language read that tag back as its language — corrupting the
  tag set and the code fence on the next update. Only the FIRST tag can carry
  the language, since compose_tags emits [language, "snippet", *caller].
- #2077 MCP update_snippet mapped "" to "unchanged", so no field could ever be
  cleared and no snippet detached from its project. Now an omitted field is left
  alone, an empty string clears, and project_id follows the -1 = detach
  convention. A service-level UNSET sentinel keeps None available as the clear.
- #2078 surface parity: adds delete_snippet (MCP had none, so a wrong snippet
  could not be retired by the agent that recorded it), locations on MCP create
  and update, system_ids through the REST routes and the editor, and the
  near-duplicate gate on REST create with a "record it anyway" escape.
- #2079 project scoping: list_snippets takes project_id through the service, the
  MCP tool and the REST route, defaulting to every project — reaching across
  projects is the point when the helper you need was written elsewhere.

Sharing the list across owners is deliberately NOT in here: query_knowledge is
shared with the Knowledge browse surface, so widening it changes behaviour well
beyond snippets. Left open on #2079 for a scope decision.

bvandeusenandClaude Opus 4.8 7a81b7333e feat(scribe): snippet merge UI — multi-select merge, repeatable locations

Step 3 of the snippet-merge milestone (#231): the human surfaces for
merge + multi-location, at v1 quality.

Frontend:
- SnippetListView: a Select mode (checkbox on each card) → a sticky action
  bar → a merge modal that lets you pick which selected snippet is the
  canonical (the others fold in and go to trash). Accent border on selected
  cards, Moss action buttons (Hybrid rule).
- SnippetEditorView: the single Location fieldset becomes a repeatable
  locations list (add/remove rows), so editing a merged snippet no longer
  collapses its call sites — no data loss. Sends `locations`.
- SnippetDetailView: renders every location (Location vs Locations label).
- api/snippets.ts: SnippetLocation type, `locations` on fields/input,
  mergeSnippets().

Backend (editor enablement):
- create_snippet service + POST route accept an optional `locations` list;
  PATCH route forwards `locations` — so the editor's location list works
  uniformly on create and edit. Single repo/path/symbol remain the
  one-location shorthand (MCP create contract unchanged).

Step 2 of the snippet-merge milestone (#231). The dedup gate only PREVENTS
new near-duplicates; merge is the CURE for the ones already scattered.

- services/snippets.py: merge_snippets(user_id, target_id, source_ids) —
  keep the target's scalar fields (name/when_to_use/signature/language/
  code), union the sources' locations + extra tags onto it (so the survivor
  carries every call site as a location), trash the sources (recoverable),
  re-embed the survivor. Pure merge_snippet_fields() factored out for unit
  testing. Returns (survivor_note, merged_ids).
- mcp/tools/snippets.py: merge_snippets(target_id, source_ids) tool (5th),
  and a create_snippet dedup-path nudge toward merge over a forced copy.
- routes/snippets.py: POST /api/snippets/<id>/merge {source_ids} — share-
  aware (can_write target + every source, rule #78) with a same-owner guard
  (cross-owner merge is out of scope).
- plugin reusing-code skill + MCP _INSTRUCTIONS: point found-duplicates at
  merge as the cure (rule #119 surfaces, not a Scribe rule). plugin.json
  0.1.13 -> 0.1.14 in the same change (the #1040 marketplace-ship lesson).
- Tests: pure merge-helper union/dedup; MCP tool (requires a source,
  survivor+merged_ids, not-found); route handler + 5-tool registration.

Step 6 of the Drafter recall milestone (#227): a human-facing surface for
the reusable-code snippets that agents record via MCP, plus the REST API
behind it. Backend embeds snippets inline on create/update so they're
recallable immediately, not only after a restart.

Backend:
- routes/snippets.py: GET/POST /api/snippets, GET/PATCH/DELETE
  /api/snippets/<id>. Share-aware per rule #78 (get_note_for_user +
  can_write_note), writes performed as the owner; list owner-scoped —
  mirrors routes/notes.py. Registered in app.py.
- services/snippets.py: embed on create/update via a _embed_snippet
  fire-and-forget helper, covering BOTH the MCP tool and the REST route
  by construction. A snippet's value is immediate recall, so it can't wait
  for the startup-only backfill (see issue: MCP create path doesn't embed
  inline for notes/tasks generally).
- tests/test_routes_snippets.py: structural registration + handler/service
  contract + PATCH-field ↔ update_snippet-kwarg parity (rule #33).

Frontend (Vue 3 + TS):
- api/snippets.ts: typed client, modeled on api/systems.ts.
- views: SnippetListView (search, skeleton/empty/error states),
  SnippetDetailView (read + copy-to-clipboard, ConfirmDialog delete),
  SnippetEditorView (create/edit all fields, Ctrl/Cmd+S, Esc, autofocus,
  validation). v1 quality per rules #24/#27.
- router: /snippets, /snippets/new, /snippets/:id, /snippets/:id/edit.
- NoteType union widened to include 'snippet'; Snippets nav link added to
  AppHeader (desktop pill bar + mobile menu).
- Design system: Moss --color-action-primary for action buttons, accent
  --color-primary reserved for tags/brand (Hybrid rule); focus rings;
  JetBrains Mono for code/name/signature/location.
