Scribe's record kinds get reached for interchangeably, and the moment of
choice is the only moment a correction is cheap. Rule 119 puts product
guidance in the instruction surfaces, so the docstring is where this
belongs — but a docstring that only documents parameters answers "how do I
call this" and leaves "should I be calling this at all" unasked.

The gap was lopsided. create_rule and start_planning already carried real
disambiguators; create_note — far and away the highest-volume surface —
carried none at all. The guidance sat in the rarest tool and was missing
from the most common one.

Each surface now opens with ONE deciding question in its own terms rather
than a pasted block:

  create_note     WHAT ELSE COULD HOLD THIS?      note is right when nothing
                                                  is owed and nothing enforces
  create_task     IS ANYTHING ACTUALLY OWED?      nothing owed -> note;
                                                  an arc -> start_planning
  create_snippet  SHAPE, OR ADVICE?               a snippet is code with a
                                                  LOCATION
  create_process  FOLLOWED, OR READ?              applies uninvoked -> rule

create_project_rule now points at the entity check too; it had only ever
covered rule-vs-rule scope.

The guard asserts STRUCTURE, never wording: each surface must name at least
two siblings. Pinning phrasing would make every improvement a test failure,
and a test that punishes editing is a test that gets deleted. Its second
half asserts the Args: block survives — the first check is satisfiable by
turning a docstring into an essay about the other tools, which would be a
worse contract than the one being fixed.

The guard caught two gaps on its first run, one of them its own: "design
system" is hard-wrapped across a line break in create_rule, so matching the
raw docstring reported it absent. _doc() now flattens whitespace. It also
caught start_planning naming only one alternative, which was true and is
now fixed.

Deliberately NOT built: an intent-router tool. It has a bootstrapping
problem — it is itself a tool that must be reached for — and MCP clients
already list every tool's description. Recorded in #3123; build it only if
wrong-surface reaches survive this.

DRY pass 3's remainder. Both halves start from enumeration, because the task's
candidate list was hypotheses and the process requires counting before
proposing — and counting changed the answer twice.

## The list_* family: a limit with no offset

Enumerated all 19 `list_*` MCP tools first. They are genuinely heterogeneous —
8 take `project_id`, 6 take `limit`, six take no arguments at all — so a
common-parameter guard would invent a convention the API does not have, which
is the over-DRY trap (§5). One contract IS real: a `limit` without an `offset`
is a truncation with no continuation. The caller is told there are 250 results,
handed 50, and given no way to ask for the rest.

Two tools had it, and both were capped over a service that already accepted an
offset: `snippets_svc.list_snippets(offset=0)` was simply not exposed, and
`list_processes` passed a hardcoded `offset=0` into `query_knowledge`. The
capability existed one layer down in both; only the door was missing — the
missing-sibling shape exactly. Both now expose it.

`tests/test_mcp_list_family.py` guards it, with `list_tags` exempted for a
stated reason (a ranked top-N over a bounded vocabulary has no "rest" to page
into). Candidates derived, decision explicit, same design as test_mcp_auth —
plus the reverse checks: a stale exemption, and an offset with no limit, which
would page through an unbounded result set. Verified non-vacuous by running the
sweep against the pre-fix tree, where it fails naming both tools.

## The verb pairs: no finding, which is the finding

`preview`/`apply` and `dry_run`/`commit` do not exist anywhere in the 102
tools — those were guesses about a shape Scribe never adopted. `count_*` does
not exist either. Of the create/delete stems only `project_rule` lacks a
`delete_X`, and deliberately: a project rule IS a rule, `delete_rule` removes
it, and the docstring says so. `force` sits on 6 of 7 duplicate-gated creates;
the exception is `create_system`, whose gate is an exact normalized-NAME match
rather than a semantic near-match — forcing it would split one area's records
across two piles, which its own message explains. No guard added: it would
need a seven-entry exemption list to defend against a hypothetical. Recorded
on the leave-alone list instead, which the process asks for by name.

## The hook config preamble

Not 3 of 6 hooks as recorded — all FIVE carried their own copy, and of four
lines rather than two. The extra two are a guard treating an unexpanded
`${...}` placeholder as unset, so it is never sent as a garbage Bearer token:
precisely the correctness detail a sixth hook would omit with nothing failing
loudly. Now `scribe_config` in scribe_defs.sh, which also declares the two
names it owns. It sets globals rather than echoing, so a token never passes
through a subshell's output where xtrace or a log could catch it, and returns
a status so a caller can bail (`|| exit 0`) or continue degraded — the
session-context hook still owes its static floor when Scribe is unconfigured.

`check_plugin.py` now runs shellcheck with `-x`. Without it the shared helpers
were invisible: every variable they set read as unassigned and every bug inside
them went unlinted at the call site, which is the opposite of what sharing them
was for. All twelve fail-open scenarios still pass, and all five hooks were
probed live against the instance — prior_art and after_write both still name
canon, autoinject returns context, session_context serves 11k chars of rules,
sync_processes stays silent. Plugin 0.1.46 (#2209).

Operator's generalization of #2582: the benefit of nearly every stored
process is the accumulated SHAPE — steps, taxonomy, quality bar — and a
process must not force anything or overwrite the intent of the request
that invoked it. create_process now states the authoring side of the
composition contract: no embedded approach mandates, no pre-granted
approvals, clarify steps seed from the conversation instead of
re-asking it.

(All three stored processes were also audited: DRY Pass and Rulebook
Review were already propose-approve-apply with no forcing language;
both gained the seeded-clarify line — data changes, live already.)

Extends #2582's fix per the operator's direction: a stored Process must
incorporate the context it was triggered with, not displace it. No new
plumbing needed — the live context is already in the session; what was
missing is the stated contract. get_process now carries it: live
constraints/scope/focus fold into the procedure and override its
defaults where they disagree; a clarify step asks only what the
conversation has NOT already answered (confirm interpretations, don't
re-ask); stated concerns become lenses the procedure applies, not text
it discards. The sync-generated skill stubs state the short form.

Survey pass 3 (#2250) tabulated capabilities per record kind. Processes came
out lowest on every column, and they are the kind with the most authority:
build_process_manifest turns each one into a skill file on the operator's
machine that auto-surfaces and is followed as written — its own docstring calls
it "the most consequential passive surface Scribe has."

Three gaps closed.

NO PULL TELEMETRY (#2476). get_process recorded nothing, while the auto-inject
menu header names get_process as the way to open that kind. Every note is
embedded regardless of note_type, so a Process is surfaceable — and the getter
the product points at was the one getter that recorded nothing, leaving every
Process permanently at zero pulls and looking like dead weight beside kinds
that merely had a counter.

get_note's own comment already listed processes as a reason to record pulls.
The fix for #2245 covered notes, tasks and snippets: it enumerated the kinds
someone thought of rather than the kinds that exist.

NO DEDUP GATE. create_process had no near-duplicate check and no force flag,
while notes, tasks, snippets and rules all have both. It matters more here than
elsewhere: two near-identical procedures don't just bloat the corpus, they
compete to be followed, and which one wins is decided by a slug collision.

NO DELETE. list/create/get/update, no delete — a kind that reads as one you
cannot retire. Deletion was always possible via delete_note, since a Process is
a note and the trash is kind-agnostic, so this was discoverability rather than
capability. delete_process checks note_type before trashing: the tool is
reached for by name, and letting it destroy an ordinary note whose id happened
to resolve would be a destructive action taken on a mistyped argument.

THE GUARD, which is the part that stops a fourth repeat.

tests/test_mcp_pull_telemetry.py discovers every get_* MCP tool by AST and
requires a record_pulled from any that loads a single note. Not a list of
getters — a get_<newkind> added tomorrow is covered the moment it loads a note
the way the others do. get_milestone is correctly excluded: it calls list_notes
for a milestone's steps, which is a surfacing, not an opening.

The loader NAMES are a list, and that residual weakness is pinned against a
rename rather than papered over. An earlier draft tried to discover new loaders
by return annotation and would have failed on create_note — which also returns
a Note. Readers and writers aren't distinguishable by type, so the honest
version is a pinned list, a non-empty assertion, and a docstring saying which
hole remains.

test_register_attaches_four_tools became a derived check of the module's public
coroutines, so the next tool added can't be left unregistered.

MCP _INSTRUCTIONS updated: product behaviour belongs in the instruction
surfaces, not in a rule (rule #119).

Option B, per the operator. Closes the last inconsistency from the ACL work.

The agent path had drifted into an indefensible position: delete_snippet honoured
editor shares (I made it share-aware so widening the read wouldn't let a VIEWER
trash things) while update_snippet still resolved through the owner-only
notes.get_note. So through an agent you could destroy a colleague's snippet but
not improve it — and the refusal claimed "not found" for a record you could
plainly open.

Now update_snippet, merge_snippets and update_process all resolve the read scope
and then require can_write_note, matching the REST routes and the sharing UI's
own promise that viewer / editor / admin are distinct grants. A viewer grant is
refused with the actual reason ("shared with you read-only — ask its owner for
edit access, or record your own version"), because not-found would send an agent
hunting for a missing id instead of recording its own copy.

Authorised writes are performed as the OWNER, since the underlying note update is
owner-scoped and a shared editor's own id would match nothing.

Merge additionally requires each source to share the TARGET'S owner and to be
writable by the caller — merging trashes the source, so read access isn't enough,
and cross-owner merge stays out of scope (#231). Sources failing either test are
skipped rather than half-merged.

A record the caller cannot read at all still returns not-found rather than
forbidden, so the error can't be used to confirm that an id exists.

Also fixed _fake_snippet's missing user_id proactively — the same
auto-MagicMock-reads-as-foreign trap that broke CI twice (see note 2109).

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).

Renames src/fabledassistant -> src/scribe and all imports, plus the
default DB name and DB user/password (fabled -> scribe) in config +
compose. 952 refs / 154 files. Reverses the old 'internal name stays
fabledassistant' convention.

Code-only: live databases are still physically named 'fabledassistant'.
Deployed environments must set POSTGRES_DB / POSTGRES_USER (or rename the
DB) since the defaults now resolve to 'scribe'. Repo (FabledScribe), git
host (fabledsword), MCP (fabled-git) and the image name (fabledscribe)
are intentionally unchanged.

ruff check src/ clean locally; CI (typecheck + pytest) is the gate.
