79896b6356 fix: state the credential impact, not the disconnect, in the shared-URL toast
Copilot: the stale-session guard deliberately skips `disconnect()` after a
switch, and `disconnect()` can also reject (which gets its own toast), so
claiming the active session "was disconnected too" is not always true.
What is always true is that its stored tokens went with the shared blob
and it must reconnect, so the message says that instead.

3c8fdb0814 fix(web): drop the step-up retry when its prompt is cleared
The retry closure belongs to the prompt, but the two paths that clear the
step-up slot as a *consequence* of something else — the server-switch reset
and `resetOAuthRecoveryState` on disconnect — left `pendingStepUpRetryRef`
installed. The next prompt to open without a retry of its own would inherit
it, so authorizing an ambient step-up on server B ran the command server A was
left mid-way through.

Clear it in the existing mirror effect whenever the slot is null, so no arm has
to remember. A ref write in an effect, since the render-phase reset must stay
pure.

Copilot on #2237.

2ba25d63e3 fix(web): reset pending OAuth slots during render, not in an effect
`useOAuthRecovery` cleared its two server-scoped pending-OAuth slots — the
deferred re-auth and the step-up prompt — in a `useEffect` keyed on
`activeServerId`. An effect runs after the commit, so a server switch painted
one frame still carrying the previous server's re-auth banner or step-up
prompt: an authorization affordance attached to the wrong server.

Reset both during render with `useValueChange` instead. `activeServerId` is a
primitive, so it satisfies the helper's `Object.is` stability requirement, and
the previous value is read from the `setState` updater argument rather than
from `sessionRef.current`, keeping the render-phase callback pure.

`react-hooks/set-state-in-effect` did not fire on the original because the
effect read the previous value through a ref rather than from a prop or state.

The test records one entry per committed render and asserts both slots are
empty in the first frame after the switch — the pre-existing `waitFor`-based
tests pass against the effect version too.

19a39235a2 fix: terminate the OAuth connection-details refresh promise chain
The connection-details refresh effect in useOAuthRecovery voided
inspectorClient.getOAuthState() with a lone .then and no rejection
handler. In the browser that read goes through the remote OAuth store, so
it is a network round trip that can reject — a backend that is down or
restarting, a 401 on the API token, malformed stored state. void silences
no-floating-promises without terminating anything, so every such failure
became an unhandled rejection, on the initial refresh and on every
oauthComplete refresh.

Terminate the chain with a .catch that clears the panel details rather
than leaving the last successful read on screen: the panel reports the
current OAuth state, and a stale answer is indistinguishable from a fresh
one. The cancelled guard is repeated on the catch so a rejection arriving
after unmount does not write. The void stays, now with the one-line
justification AGENTS.md asks for — a synchronous useEffect body cannot
await.

Two tests cover it. Both fail against the unfixed source with unhandled
rejections, which is the failure mode itself: an unhandled rejection
fails the whole vitest run.

fcec17f5d1 fix: key the OAuth clear's active-session check on the storage key (#2217)
OAuth state is keyed by server URL, but `clearServerOAuthAndDisconnect`
decided "is this the active connection" from the catalog entry id. Those
are different identities and nothing keeps them in sync: `serverList`
enforces no URL uniqueness, so two entries with distinct ids against one
URL are a supported state — and a natural one, since separate entries are
how a user keeps different names, headers or per-server settings against
the same server.

Clearing the inactive entry therefore deleted the shared URL-keyed blob —
the active session's tokens, DCR client id and PKCE state — and, with
#2144 in, revoked its grant at the authorization server, while the id
check took the inactive branch: no live-client clear, no disconnect, no
session cleanup. The active session was left connected on credentials
that no longer existed, with nothing told to the user; the break then
surfaced somewhere else entirely, on the next refresh, 401 or reload.

The branch now compares the OAuth storage key of the cleared entry
against the active entry's, and treats a match as affecting the active
session — live-client clear, disconnect, session cleanup — exactly as
clearing the active entry does. The existing id and client-identity
checks stay on top: they guard the separate stale-session race from
#2144, and the snapshotted id they revalidate is now the active one
rather than the cleared entry's, which for a shared-key clear are not the
same. The toast says why the session went away.

The alternative, prohibiting duplicate URLs in `serverList`, would remove
a legitimate workflow to fix a bug in the consumer and could not repair
catalogs that already hold duplicates.

chore: bump version to 2.5.0 (#2213)
Bumps the root package.json from 2.4.0 to 2.5.0 on v2/main, ahead of the
v2.5.0 milestone merge into main. Applied with
`npm version minor --no-git-tag-version` — the tag is deliberately omitted
because the release is cut from main, so the tag must point at the merge
commit there rather than at a v2/main commit that is never released.

Closes #2212

afca8faaea docs: address Copilot review round 9 on #2203
Restrict the truncation guard to PLAIN scalars. `yaml` attaches a legitimate
trailing comment to quoted and block scalars too, so keying on `.comment` alone
rejected valid frontmatter — `description: "Complete value" # note` was reported
as truncated, telling the author to quote a value that was already quoted. The
regex this replaced tested the same thing by reading the first character; moving
to the node dropped the check rather than encoding it. Verified all three
shapes (double-quoted, single-quoted, block) against the parser, and added the
regression cases.

Also correct the `--max-turns 1` bullet in docs/skill-authoring.md, which
claimed the skill must be the model's first tool CALL. `collectSkillInvocations`
scans every tool_use block in the assistant event without regard to order, so a
turn calling Read and Skill together scores a hit. What actually loses the
sample is needing a tool RESULT first — that decision lands in turn two, which
never runs. The practical advice is unchanged; the mechanism now matches the
collector.

c66793bfd8 docs: address Copilot review round 8 on #2203
Ask the YAML parser what it discarded instead of re-deriving it from the raw
frontmatter text. `yaml` hangs the comment it stripped on the scalar node, so
`parseDocument(...).get(field, true).comment` IS the truncation signal: a plain
scalar that lost text has one, a quoted or block scalar never does, and
`Issue#28` (no preceding space, so no comment) keeps its full value.

That closes both findings at once. The line-locating regex only ever matched
the canonical `description:` key, so `"description":` and `description :`
populated the mapping while the guard skipped them and left verify:skills green
on a truncated listing; and the continuation scan stopped at the first blank
line, inspecting only the opening paragraph of a plain scalar that YAML happily
continues past one.

It also retires the scanning itself — three rounds of regex here each fixed one
shape and missed the next (tags and anchors, then indented continuations, now
key forms and blank lines). The node carries all of them for free, so 65 lines
of hand-rolled parsing come out. Parsing once with `parseDocument` keeps the
node view and the value view from ever disagreeing.

Tests cover the three noncanonical key forms, the blank-line continuation, and
the standalone comments that must NOT read as truncation.

0febaa0f6f docs: address Copilot review round 7 on #2203
Strip YAML properties (tags, anchors, in either order) before deciding
whether a description scalar is quoted — testing the first character alone
read `&copy "Counts # safely"` as unquoted and rejected a `#` the quotes
make harmless.

Count the positive-case floor by distinct prompt rather than by entry: the
floor exists for breadth, so five copies of one prompt cleared it while
exercising exactly the single trigger it is meant to look past. Compare on
collapsed, case-folded text so trivial edits do not read as a new situation.

Re-aim the two positive prompts that measured the wrong thing — the
project-structure case now poses a concrete "which piece handles what"
question, and the test-servers case names running a real MCP server.

5d3571597a docs: address Copilot review round 6 on #2203
The truncation guard rejected valid frontmatter. It assumed the only way
a raw scalar can exceed its parsed value is a comment, but YAML also
strips presentation syntax, so `description: &copy Some text` and
`description: !!str Some text` were both reported as truncated — naming
an unquoted `#` the value does not contain.

The length check is now gated on an actual comment marker: `#` at the
start of the scalar or preceded by whitespace, which is where YAML begins
a comment. Anchors and tags fall out before the length is consulted.
Regression cases cover both, and assert the genuine `#` case still fails
so the fix cannot pass by disarming the guard.

Also corrects the checklist, which still said an unquoted `#` lets every
check pass. That predated the verifier; verify:skills rejects it now, and
the sentence was telling authors the gate is blind to something it
catches.

No skill description or eval case changed, so skills:eval is unchanged
from round 4's 63/63. local:gate passes, 34/34. 391/391 script tests.

ec2ef5656d docs: address Copilot review round 5 on #2203
The truncation guard read only the first physical line of the scalar, so
a multiline plain scalar slipped past it:

    description: Covers boards
      #28 and #11

YAML parses that as `Covers boards`, and the first-line-only comparison
saw `Covers boards` on both sides and reported no loss — passing the
exact silent truncation the guard exists to reject.

It now walks the whole plain scalar: the value line plus every indented
continuation, whitespace-collapsed to match YAML's folding of newlines to
spaces. Quoted and block scalars are still skipped, since neither loses
text to a comment.

Two regression cases: the multiline truncation, and a multiline scalar
with no `#`, which must stay clean — the fix cannot be "reject anything
multiline".

No skill description or eval case changed, so skills:eval is unchanged

4acab97e63 docs: address Copilot review round 4 on #2203
Corrects the rationale for the five-positive floor, which was wrong. The
claim was that five prompts make a skill's rate flake-tolerant. The
evaluator scores each prompt on its own `passes / RUNS`, so the number of
prompts never enters any rate and cannot affect a threshold crossing —
`RUNS` is the only knob that does. The floor is worth keeping for
breadth: one prompt measures one phrasing, and a description that fires
on a single narrow shape would pass on its one lucky case.

The bad reasoning had reached five places — AGENTS.md, the authoring
checklist, the JSDoc, the check-site comment and the regression test —
plus the emitted message, which asserted it too. All corrected.

Moves `MIN_POSITIVE_CASES` above `validateEvalCases`'s JSDoc. It had been
inserted between the two, so the `@param`/`@returns` block documented the
constant and the function had none.

Replaces the two remaining cases answerable from `AGENTS.md`: `local-dev`'s
web-client-startup case (the rules file gives the exact command) and
`project-structure`'s clients/web-versus-core case (its tree answers it).
Both replacements probed 3/3 and measure 100%.

RUNS=5 skills:eval: 63/63, every local-dev and project-structure case at
100%. local:gate passes, 34/34.

104a05dd7f docs: address Copilot review round 3 on #2203
Replaces the last `project-structure` case that `AGENTS.md` answers — a
helper used by the CLI and TUI belongs in `core/` per its own directory
tree. This was also the only case below 100% in the previous suite, so
the static reading and the score agreed. The replacement targets the
skill's first stated purpose, locating code, which `AGENTS.md` gives no
method for; it probed 3/3 and now measures 100%.

Extends the truncation guard's tests to `when_to_use`. The guard loops
over both fields but only `description` was pinned, so dropping the
second from that list would have gone unnoticed. The new case pairs a
quoted description with an unquoted `when_to_use` and asserts the
description is not implicated.

Scopes the negative-case requirement in the prose to model-invoked
skills; round 2 scoped the checklist but left this sentence saying
"every skill file".

Refreshes the stale `~2.8k of 4k` listing figure. The other instance is
past-tense about the three-to-nine experiment and stays, now said
explicitly so two numbers do not look like a disagreement.

Records the eval's real blind spot: all three cases review identified as
`AGENTS.md`-answerable were scoring 80-100% when flagged, so a high score
does not clear a case of overlap. The eval can show a case failing; it
cannot show a passing case is well-aimed.

RUNS=5 skills:eval: 63/63. local:gate passes, 34/34.

880be3acdd docs: address Copilot review round 2 on #2203
Enforces the five-positive standard this PR established rather than only
describing it. `validateEvalCases` checked `positives === 0`, so a skill
could regress to a single prompt and still pass the gate. At RUNS=5 one
case is 20 points of that skill's reading, so a one- or two-case skill
reports a rate a single flake can move across the threshold — well-formed
to the checker, meaningless as a measurement. Zero positives keeps its
own clearer message so the common mistake keeps its diagnosis.

Scopes the eval requirement to model-invoked skills in the checklist. A
name-only skill has no eval file because nothing can measure a trigger
only a human types, so an eval there is unrunnable rather than redundant.

Aligns checklist item 1 with the `#` hazard from round 1; it named only
the unquoted colon, which is the louder of the two failure modes.

Four test fixtures asserted on one-positive eval files and legitimately
went red; they now build positives from the exported MIN_POSITIVE_CASES.
The all-positive row keeps testing the missing-negative path, with a new
row for the below-floor case. 388/388 script tests pass.

No skill description or eval case changed, so trigger behaviour is
unaffected and skills:eval is unchanged from the previous round.

50f3360d65 docs: address Copilot review round 1 on #2203
Fixes an unquoted `#` in `board-ops`'s description. YAML reads ` #28`
onward as a comment, so the parser — and Claude Code, which parses the
same way — only ever saw the description up to `Covers board`. Both
board numbers and the option-deletion hazard were absent from the
listing that decides whether the skill fires, and every check stayed
green because they look for an *empty* description and a truncated one
is still non-empty. Quoting restores all 271 characters, which is the
whole of the 3,144 vs 3,234 discrepancy the review flagged.

`parseSkill` now compares the raw scalar against what YAML kept and
errors on any loss, so the next one fails the gate rather than shipping.
Tests cover the truncated case and a legitimately quoted `#`.

Re-aims the `project-structure` Node-backend case, which `AGENTS.md`
answers via its tree and which had oscillated 80 -> 100% across runs —
the partial-overlap signature this PR documents. The replacement names
no internals and probed 4/4.

Makes the documented probe reproduce the harness: the same
`--disallowedTools` flags as `runPrompt` rather than `--allowedTools`,
`printf` instead of zsh's `print -r`, and `jq` over `tool_use` blocks
instead of a `grep` that also matched MCP server names in the init
event. The first-tool-call table is relabelled as an unrestricted probe,
since the eval cannot reach for Bash at all.

RUNS=5 skills:eval: 63/63, 62 at 100%; restoring those 90 characters
displaced nothing.

a344225e23 docs: accept several skill names in skills:eval and re-aim overlapping cases
Adds a multi-name filter to `npm run skills:eval` so a set of related
skills can be iterated together, and makes an unknown name a hard error
rather than an empty run — a typo would otherwise report a green 0/0
that reads exactly like a clean pass of the skill that was meant.

Re-aims two `local-dev` cases and one `test-servers` case that partially
overlapped `AGENTS.md`. Partial overlap oscillates across runs rather
than sitting at zero, so it reads as eval noise instead of a defect in
the case; `docs/skill-authoring.md` now records that failure mode and
the observed scores.

Widens the `test-servers` description to the "Use when …" shape and
points the `testing` skill at it, since anything needing a real server
to run against is a procedure `testing` does not carry. That growth
moves the skill listing from 2,921 to 3,144 of 4,000 characters, so the
figure recorded in AGENTS.md is updated to match.

6dd43e78ba docs: tune skill eval cases and document how to write them
`skills:eval` was at 38/46 with several skills measuring 0-33%. The low
scores were mostly bad eval cases rather than bad descriptions, for two
reasons that were nowhere written down:

- The harness runs each case with `--max-turns 1`, so the skill has to be
  the model's FIRST tool call. A prompt asking "how does X work here", or
  naming a concrete file, sends the model to Read/Grep first — a better
  answer to the question, scored as a miss. Every 0% case was one of these.
- `AGENTS.md` is resident on every turn, so a prompt it already answers is
  answered without any skill and the case can never pass.

Replace the cases that measured the wrong thing, expand every model-invoked
skill from 3 to 5 positives (negatives kept) so one flake cannot cross the
threshold, and reshape `local-dev`'s description to the action-first form.

Add `docs/skill-authoring.md` with the case shapes that fire, the ones that
cannot, and the probe-then-measure loop.

RUNS=5 npm run skills:eval: 63/63 at or above threshold, 60 at 100%,
all 18 negatives clean.

Both findings are my own comments contradicting each other, in the same file.

- The no-pin example list still named `open` and `zod`, which the array right

  what the criterion actually is: absence is a statement about the installed
  tree, not about the manifests.
- The consolidated group is described as root-OWNED aliases rather than
  `core/`'s runtime dependencies, since `@hono/node-server` is reached from web
  client code alone and is here for the resolution reason, not because `core/`

Two suppressed comments, both accurate.

- Pin zod, zod/v4 and open to the root in vitest.shared.mts, and add matching
  paths to the three clients/web tsconfigs. The claim they replace — that these
  resolve unambiguously by walk-up — was wrong: both still sit at the top level
  of clients/web/node_modules as transitive copies (zod under
  eslint-plugin-react-hooks, open under Storybook), so an unpinned bare import
  from a web test resolved the client copy while core/ and the SDK packages
  resolved the root's. For open that is only wasteful; for zod it is a schema
  built by one copy and an instanceof check made by the other across the whole
  @modelcontextprotocol/* surface. zod is deduped as well, and zod/v4 gets its
  own entry because first-party code imports both specifiers and pinning one
  would split the package rather than collapse it.
- Update the consumer comments that #2195 falsified. clients/web/vite.config.ts
  (three places) and server/start-vite-dev-server.ts all still said the shared
  aliases resolve pino/hono and friends from clients/web/node_modules; they now
  state the split — react and react-dom from the client install, everything
  root-declared from the repo root.
- local-dev skill: replace the wrong 'resolves unambiguously' list with the
  distinction that actually matters. Deleting a declaration is not the same as
  the package resolving from the root, because chokidar, zod, open and react
  all sit in a client install transitively; check the install, not the manifest.
  ajv, commander and undici carry no pin because no client install has a copy.

npm run local:gate passes from a cold tsc build.

- clients/web/tsconfig.{app,node,test}.json: repoint the pino, hono,
  hono/streaming, @hono/node-server, atomically, chokidar and @napi-rs/keyring
  path mappings from ./node_modules to ../../node_modules. The stale mappings
  were not failing the build — an unresolvable paths entry falls back to
  ordinary walk-up resolution, which finds the root copy — but chokidar is the
  case where the fallback never runs: Vite's transitive copy still sits under
  clients/web, so tsc was type-checking against the client's copy while Vitest
  and the shipped bundle both resolved the root's. Same version today, silent
  skew tomorrow. Both path prefixes now carry a comment saying which ownership
  each one asserts.
- local-dev skill: the consolidation rationale no longer groups commander, open
  and @hono/node-server (client-imported) with the core/ set, no longer claims
  #2195 moved undici (it was already root-only), and no longer implies every
  root-declared package has an alias.

npm run local:gate passes with clients/web/node_modules/.tmp cleared, so the
tsc results are from a cold build rather than an incremental cache.

f62cfbaeeb chore: address Copilot review on #2200
- Complete the bundler external lists against the AGENTS.md invariant rather
  than against today's reachability: chokidar, hono and react to clients/cli,
  chokidar and hono to clients/tui, react to the web runner. Every root-declared
  package core/ imports at runtime is now named in all three, so a new import in
  core/ cannot silently inline one.
- AGENTS.md: split the single over-broad bullet in two. commander, open,
  @hono/node-server, vite and @vitejs/plugin-react are root dependencies reached
  only from client code, so they are not part of the core/ set and need naming
  only in the external list of the client that imports them. Give the
  vitest.shared.mts pins their own rule, stating the react/react-dom exception
  instead of implying every root-owned package is aliased to the root.
- vitest.shared.mts: the umbrella comment now says root-OWNED rather than root
  runtime dependency — express is test-only and lives in the root
  devDependencies — and notes that the list is deliberately not the complete
  root set, since a package that resolves unambiguously needs no pin.
- local-dev skill: document why react/react-dom stay client-pinned, which the
  previous text contradicted.

npm run local:gate and npm run verify:bundle-externals pass.

e76e32caa9 docs: separate peer-constrained copies from unconstrained transitives
Copilot review round 3. Docs only.

The round-2 wording said every surviving copy is pinned by its holder's peer
range, in the same paragraph that documents cli's @types/node 24.13.1 against
the root's 24.13.3 — a transitive, which no peer range constrains. The rationale
contradicted its own example.

Both files now split the two mechanisms and grade them:

- A peer copy is constrained by its holder's peer range, which is a real pin only
  when that range is exact. @vitest/browser-playwright pins vitest to a single
  version (hence the exact trio). eslint-plugin-react-refresh accepts ^9 || ^10,
  so the eslint copies agree only because npm resolves the same latest in both
  installs — a coincidence, not a guarantee.
- A transitive copy is constrained by nothing of ours, and cli's @types/node has
  already diverged. It was 24.13.1 on v2/main too: a declared ^24.12.4 still
  loses to a nearer transitive.

Nothing gates either, and verify:dep-lockstep is not that gate.

613c4949a4 docs: correct the scope claims in the toolchain rule
Copilot review round 2. Docs only; no manifest or lockfile change.

Two claims were wrong:

- "A tool one client runs stays in that client" is contradicted by the
  manifests — tsup is declared in web, cli and tui, and vite in web and tui on
  top of the root runtime dependency that --web --dev needs. The boundary is
  "used by every client", not "used by one"; anything narrower stays put whether
  one client declares it or several do. Both are out of scope here and say so.

- verify:dep-lockstep was named as the guard that the surviving copies agree. It
  is not: it derives its candidate set from what each tsc program resolves, so a
  tool binary never enters a program and is outside the set no matter how far it
  drifts — and cli's @types/node 24.13.1 against the root's 24.13.3 is a live
  skew that passes for the same reason. Both files now state the narrower
  guarantee, say that nothing gates the binaries automatically, note that each
  surviving copy is pinned by its holder's peer range, and give
  `npm exec -- which` as the manual check.

edef659fd9 fix: pin the vitest trio exactly, and document the peer/transitive exceptions
Copilot review round 1.

@vitest/browser-playwright declares an EXACT peer on vitest ("vitest":
"4.1.10"), so that package — not the root's range — decides which vitest lands in
clients/web. Dropping web's own vitest declaration left the root free to resolve
4.1.11 while web's peer stayed at 4.1.10, so web's tests ran on one vitest while
loading a @vitest/coverage-v8 provider built against another. Both still passed,
which is the bad part.

vitest and @vitest/coverage-v8 at the root and @vitest/browser-playwright in
clients/web are now pinned exactly to 4.1.10 and move together, the same
discipline as the exact prettier pin (#1790).

The docs also claimed more than the change delivers. npm auto-installs an unmet
peer into the install that needs it, and a client install cannot see the root's
tree — so web's eslint-plugin-react-refresh / -storybook and the TUI's
eslint-plugin-react-hooks each pull a client-local eslint, and web's
Storybook/Vitest stack pulls a local typescript and vitest; @types/express
hoists an @types/node into web and cli. Those copies sit nearer than the root's
and win. AGENTS.md and the local-dev skill now say so, and state what the
consolidation actually buys: one declaration and one place to bump, with
verify:dep-lockstep as the guard that the copies agree.

1f5c32940d chore: consolidate duplicated runtime dependencies into the root package.json
Every runtime dependency core/ imports is now declared once, in the repo-root
package.json, and nowhere else. Deleting the client-side copies does not merely
align them: a package installs only into an install root that declares it, so
with no second declaration a second copy cannot be created at all — the failure
class #1896 was opened for and #1965/#2029 built verify:dep-lockstep to detect.

- clients/{web,cli,tui,launcher}: dropped ajv, atomically, chokidar, commander,
  open, pino, zod, @napi-rs/keyring, hono, @hono/node-server and react, as each
  applied. clients/cli and clients/launcher now declare no runtime dependencies.
- Root hono floor raised ^4.12.18 -> ^4.13.1, keeping the higher of the two
  ranges that were in the tree rather than silently lowering web's.
- tsup external lists: added ajv and zod to all three bundles, plus atomically
  and open (cli) and atomically (tui). tsup externalizes only what the nearest
  manifest declares, so a package that moves to the root is inlined unless it is
  named explicitly.
- vitest.shared.mts: repointed the pino, hono, @hono/node-server, atomically,
  chokidar and @napi-rs/keyring pins from <client>/node_modules to the repo
  root, joining express, yaml and proper-lockfile. Left behind they would
  resolve to a directory that no longer exists, or to a transitive copy an
  unrelated dependency dragged in. react and react-dom stay client-pinned so
  the pair stays version-matched within an install.
- Docs: AGENTS.md dependency placement, the root README and the local-dev skill
  describe the consolidated layout.

verify:dep-lockstep candidate set: 4 -> 2 (hono and pino fell out; only
@standard-schema/spec and zod still reach one tsc program from two installs).
npm run local:gate and npm run pack:verify both pass.

327c8d67fa chore: consolidate shared toolchain devDependencies into the root package.json
Declare the toolchain every client uses once, at the repo root, and delete the
per-client copies: eslint, @eslint/js, typescript-eslint, globals, prettier and
typescript (all five manifests), plus vitest, @vitest/coverage-v8 and
@types/node (four). Adds the latter three to the root manifest; the first six
were already there.

Every client reaches the root copy by walk-up — npm run puts each ancestor
node_modules/.bin on PATH, and Node and TypeScript resolve modules and @types
the same way — so nothing about the client scripts changes. clients/launcher now
declares no devDependencies at all and its validate is unchanged.

The copies had already drifted: globals sat at ^17.7.0 at the root against
^17.4.0 in all four clients, and typescript-eslint at ^8.65.0 against ^8.56.1.
Consolidating takes the root's version in both cases, and makes the exact
prettier pin (#1790) a single pin rather than five that can diverge.

Tools only one client runs stay where they are — tsup, tsx, vite, vite-node,
playwright, storybook, happy-dom, ink-testing-library, and each client's own
@types/*.

Documents the rule in AGENTS.md's Dependency placement section and the reasoning
in the local-dev skill.

d2a5e91e4a Merge branch 'v2/main' into v2/chore/2163-agent-skills
Brings in #2192 (react-hooks lint over `core/react/`) and #2194. All the code,
`eslint.config.js` and the new root devDependency merged cleanly; three
conflicts, all in files this PR refactored.

- `.github/copilot-instructions.md` — modify/delete again. Kept deleted; the
  line v2/main added there restates AGENTS.md rules that arrive in AGENTS.md.
- `AGENTS.md` — two of the three incoming hunks merged cleanly, both of them
  RULES, into the sections that survived the refactor: `exhaustive-deps` is
  `error` in every React scope including `core/react/**`, and
  `set-state-in-effect` now covers `core/react/` with `clients/tui` called out
  as the exception. The third was a `validate:core` bullet inside the pre-push
  gate section this PR moved wholesale to docs/quality-gate.md, so its mechanism
  went there instead — including why the plugin has to be a ROOT devDependency
  (Node resolution walks up, not down, so a client-local copy is unreachable).
- `README.md` — the incoming paragraph was added to the quality-gate section
  this README no longer carries. Moved verbatim to docs/quality-gate.md, beside
  the type-aware-lint paragraph it belongs with.

Ran `npm install` for the new devDependency; `npm run validate` passes.

f95abb2715 chore: tighten the testing skill's description
Measured before and after at the same sample size (n=4), with the six other
model-invoked skills unchanged:

  which command runs the TUI suite      25% → 100%
  asserting on a Mantine transition     50% → 100%
  which tier spawns the built binary    25% → 100%

The lever is the description's SHAPE, not its length: leading with the actions
and then enumerating concrete situations ("Use when … ; when … ; when …") beats
a noun-phrase list of contents ending in a generic "use for any question
about …". The same edit took `pre-push-gate` from 3/5 to 5/5 earlier.

Re-ran the full eval to check the change did not simply move attention off
another skill, which is the failure the previous commit recorded: 40/46, up from
38/46, and the failing set is strictly smaller — `testing` went from three
failures to one, nothing else moved. That remaining case measured 100% in
isolation and 67% in the full run, which is sampling variance rather than a
finding.

AGENTS.md now extends the re-run rule to cover a description edit, not just a
flip, and records the shape that works.

26d70e00e7 chore: make issue-create and issue-triage model-invocable
`release` is now the only skill reachable by name alone, which is right: nobody
cuts a release by implication, whereas "file an issue for this" and "triage the
new issues" are both ordinary prose instructions.

Eval cases committed for both; each measured 5/5 at RUNS=3. One initial case
was rebuilt rather than tuned: "file an issue for the flaky Storybook test"
scored 0% because its SUBJECT was unresolved — the model went off grepping for
which test was flaky instead of reaching for the filing procedure. A trigger
case must not make the model investigate before it can act.

The full eval across all nine model-invoked skills reports a cost worth having
in writing, and it contradicts the justification given for the previous flip.
Every negative case still passes 100%, so there is no over-triggering — but the
skills that were already model-invoked measurably LOST trigger rate:
`project-structure` fell from 100% to 0% on two cases (n=4) and `testing` from
3/5 to 2/5, while all six newly flipped skills measured 100%.

So the ceiling is attention, not characters: the listing sat at 2.8k of 4k
throughout, and "the budget is not tight" was the wrong reason to think flipping
was free. AGENTS.md now records this, and requires the FULL eval to be re-run
after any flip rather than just the new skill's own cases.

Two of project-structure's three cases are also the invalid-case pattern this
file already documents — `core/auth/` is described in the AGENTS.md tree, so a
model answering "which package owns the secret storage backends" without a skill
is correct rather than failing. `testing`'s cases are not, and it was the weaker
of the two before this change as well.

55578ac478 chore: address Copilot review round 3 (#2192)
Seeding the settings draft during render made `useSettingsDraft` call
`resolveInitial` there, and App.tsx passes `lastPersistedSettings.resolve`.
That resolver was neither pure nor current:

- it could `recordsRef.current.delete(...)`, a shared-state mutation that a
  render React replays under StrictMode or abandons would run an
  unpredictable number of times;
- it read `serversRef`, which is mirrored in a passive effect and so trails
  `servers` by one flush — so on exactly the render where a refreshed list
  arrives, it answered from the previous commit's list. That render is the
  one that seeds the draft.

`resolve` now reads `servers` directly and only reads. Eviction moves to an
effect: nothing depended on it happening at a particular moment, it only
keeps a dead record from being re-checked on every later write. Reading
`servers` also makes the supersession test fire a render earlier, which is
the right direction — the record is being checked against a list that has
genuinely been re-read.

`resolve`'s identity now changes with the list, so the test harness
delegates to the current hook result instead of handing back a snapshot from
the first render; a snapshot would have closed over the initial list and
made `setServers` look like a no-op. New test asserts `resolve` answers from
the list of the render it is called in, verified to fail against the ref
read.

546dacffe2 chore: address Copilot review round 2 (#2192)
- `useEmaIdpLoginState` attributed a read to the wrong issuer. A bare
  `EmaIdpLoginState` carries the previous issuer's answer over to a new one
  until a fresh read lands — and if that read fails, indefinitely, so the
  settings surface reports "logged in" for an IdP nobody authenticated
  against. Round 1's `.catch()` made that worse by design, and the test
  added with it asserted the wrong behaviour outright.

  State is now the pair (issuer, value) and `loginState` derives from it, so
  a mismatch reports "none". A monotonic read token — the device
  `useInitialConfig` already uses — drops completions that were overtaken,
  including a read still in flight when `logout` clears the session; issuer
  keying cannot catch those, since both carry the same issuer. Both guards
  are pinned by tests verified to fail without them.

  Deriving the value also removed the last synchronous commit on that path,
  so the `set-state-in-effect` suppression is gone — one fewer than the PR
  started with.

- The draft-seeding change had no test that could tell it from the effect
  it replaced: the regression is a committed frame, and RTL flushes passive
  effects before any assertion on `result.current`. Both hooks now have a
  commit-level trace recorded from inside the tree, asserting the previous
  target's (or session's) draft is never committed for the new one. Both
  were verified to fail against the effect implementation.

94a71f48bc chore: make the workflow skills model-invocable
`disable-model-invocation: true` does not merely make a skill prefer `/name` —
the model cannot invoke it at all, and its description is absent from the skill
listing. So "create a PR for #2163", which is how that work actually starts,
could never reach `pr-flow`. The original rationale ("procedures with side
effects we'd invoke by name anyway") conflates invoking a skill, which only
loads instructions, with performing the procedure it describes.

Flipped `pr-flow`, `pre-push-gate`, `board-ops` and `test-servers` to
model-invocable. `user-invocable` is an independent axis, so this is purely
additive — every `/name` still works. `issue-create`, `issue-triage` and
`release` stay deliberate.

`board-ops` is in the set because `pr-flow` and `issue-create` delegate their
card steps to it: a pointer from a model-invocable skill to a manual-only one is
a dead end for the model.

Costs weighed: the listing share goes 1,199 → 2,256 of 4,000, and a spurious
load costs ~250 characters where a missed one costs a wrong base branch or an
unsigned commit. The rules stay resident in AGENTS.md either way — this improves
the odds of getting the procedure too, it does not become the guarantee.

Eval cases committed for all four, measured at RUNS=3: pre-push-gate, board-ops
and test-servers 5/5; pr-flow 4/5, with "take it through to a pull request" at
100% and the Copilot-review case borderline. Three initial cases were replaced
rather than tuned green: their answers are resident in AGENTS.md, so the model
answering without the skill is correct behaviour, not a miss — the rule this
file already records about what makes a valid trigger case.

AGENTS.md's maintenance rule now says to default to `false` and explains why,
so the advice this change walks back does not get re-applied.

7e6d6c0bc1 chore: address Copilot review round 1 (#2192)
- `useEmaIdpLoginState`: the effect-triggered `refresh()` was discarded with

  `storage.getIdpSession`, which rejects when the backend is unreachable.
  Terminate with `.catch()` and leave `loginState` untouched, as `logout`

  rejection escapes.
- Correct the history: the plugin was *client-local*, declared by both
  `clients/web` and `clients/tui`. The root could reach neither, since Node
  resolution walks up rather than down — that, not web-exclusivity, is why
  `core/react/` went unlinted.
- Correct the enforcement claim: `clients/tui` registers the plugin but
  deliberately enables only `rules-of-hooks` and `exhaustive-deps`, so
  `set-state-in-effect` and `refs` hold for `clients/web` and `core/react/`
  only. Says so in AGENTS.md and in the Copilot mirror, which would
  otherwise have reviewers cite rules the TUI gate does not run.

9ced0fd150 chore: lint core/react with eslint-plugin-react-hooks (#2192)
`eslint-plugin-react-hooks` was a `clients/web` devDependency only, and each
client's `eslint .` is scoped to its own directory — so the whole hook rule
set had never looked at `core/react/`, a directory of nothing but React
hooks. "Neither surface has JSX" was the stated reason and was never a good
one: the rules judge hooks, not JSX.

Add the plugin at the root and apply it in a `core/react/**` block (scoped
there rather than to all of `core/**`, since the rules key off the `use`
prefix), with `exhaustive-deps` promoted to `error` as `clients/web` does.

Resolve the 15 findings it then reports:

- `useSettingsDraft` / `useClientSettingsDraft` seed their draft during
  render instead of in a `targetId`/`opened`-keyed effect, so the previous
  target's values never reach the DOM — the same rule `clients/web` spells
  `useValueChange`. Their "latest value" refs move from render-time writes
  into an effect; every reader (the debounce timer, `flush`, `onChange`)
  runs after a commit, so a post-commit write is what they need.
- The three async loaders keep their effects behind justified inline
  disables: `set-state-in-effect` follows a call into an async function
  without modelling the `await`, verified against a minimal hook whose only
  setState is in a continuation.
- `useInitialConfig`'s cleanup bump keeps reading `generation.current` at
  teardown — the rule's "copy it into a variable" advice would restore a
  stale request token and let a superseded response commit.

  it lands in the section that stayed.
- `README.md` — same shape, one tree line. This README no longer enumerates
  `core/`'s subdirectories at all, so the substance went where that content now
  lives: `docs/architecture.md` and the `project-structure` skill's core table.

place rather than the three it used to occupy.
