Superpowered Dependabot. Auto-discover all outdated packages, preview them grouped by severity so you can snooze any you are not ready for, audit overrides, apply codebase migrations for major bumps, resolve dependency conflicts, and run the quality gate. In CI it runs unattended (no preview); interactively it shows the preview first. On a `main`/`master` run it opens the PR and merges it once checks are green, then cleans up locally; on any other branch it pushes and leaves the PR to you.

## Pre-flight: Worktree check

This wrapper writes a new `pnpm-lock.yaml` and opens a PR, both belong on the main checkout, not a per-SPEC worktree branch. If invoked from a linked worktree, reject hard with a message that surfaces the cached state from main so the user knows whether action is even pending.

Detection (run this first, before anything else):

```bash
. .gaia/scripts/main-only-lib.sh
gaia_update_deps_state_line() {
  local cache_file="$1"
  [ -f "$cache_file" ] && command -v jq >/dev/null 2>&1 || return 0
  local outdated_count checked_at
  outdated_count="$(jq -r '.outdatedCount // 0' "$cache_file" 2>/dev/null)"
  checked_at="$(jq -r '.checkedAt // 0' "$cache_file" 2>/dev/null)"
  [ -n "$outdated_count" ] && [ -n "$checked_at" ] && [ "$checked_at" != "0" ] || return 0
  local now age ago_unit ago_value
  now=$(date +%s)
  age=$((now - checked_at))
  # Format age as <Nm ago> / <Nh ago> / <Nd ago>.
  ago_unit="s"; ago_value="$age"
  if [ "$age" -ge 86400 ]; then ago_unit="d"; ago_value=$((age / 86400));
  elif [ "$age" -ge 3600 ]; then ago_unit="h"; ago_value=$((age / 3600));
  elif [ "$age" -ge 60 ]; then ago_unit="m"; ago_value=$((age / 60));
  fi
  printf 'Cached on main: %s packages outdated (last checked %s%s ago).\n' "$outdated_count" "$ago_value" "$ago_unit"
}
gaia_refuse_if_worktree "/update-deps" gaia_update_deps_state_line || exit 1
```

If the detection does not fire, fall through to the existing `## Pre-flight: Branch check` section.

## Pre-flight: Branch check

```bash
git branch --show-current
```

If the current branch is `main` or `master` **and not running in CI**, set a flag (`SHOULD_CREATE_BRANCH=true`) but **do not create the branch yet**, branch creation is deferred until after Phase 1 confirms there are packages to update. Creating a branch when there is nothing to update pollutes the branch list.

In CI (`CI=true`, set by GitHub Actions, GitLab CI, CircleCI, and most CI providers), skip branch creation, the workflow owns branch management and pre-creates the appropriate branch before this skill runs.

Otherwise set `SHOULD_CREATE_BRANCH=false` and proceed on the current branch.

## Composition: --scope &lt;group-name&gt;

When invoked with `--scope <group-name>` (e.g. `/update-deps --scope react-router`):

- Skip Phase 0 (override audit), out of scope for a single-group run.
- Skip the discovery + preview phase, no preview runs in `--scope`; the
  group's members are known from the companion-group table.
- Skip wave classification, the run is implicitly a single group; treat it
  as Wave A if all members are minor/patch, else Wave B.
- Wave A / Wave B still apply, scoped to the named group's members
  in root `package.json`.
- Quality gate, return value, and final report still run.

Used by the GAIA CI update-deps workflow's wave-B matrix shards to fan
out one PR per major-bump group.

## Companion groups (reference)

The fixed table mapping each package to its group. `gaia update-deps run`
resolves grouping internally and is the source of
truth at runtime; every emitted entry already carries its resolved `group`.
**When any member of a group is outdated, all members present in `package.json`
update together**, so a group moves as one unit (and snoozes as one unit).

Packages not matched form singleton groups. `typescript` is deliberately one of
them: a compiler bump and an ambient type-definition bump (`@types/node`) carry
independent risk and independent migration guides, so they never move as a unit.

## Phase 1: Discover, preview, decide (orchestrator)

Discover deterministically via the CLI primitive, the single source of truth for
grouping, the ESLint 9.x cap, the `gaia.updateDepsHold` config hold, and the
release-age cooldown (all already applied):

```bash
updates_json="$(mktemp)"
.gaia/cli/gaia update-deps run --emit-updates "$updates_json"
```

Read the payload. If `total_count` is `0`, print `All packages are up to date.`
and exit (no branch, no changes). Each `wave_a[]` and `wave_b[].packages[]` entry
carries `bucket` (`patch` | `minor` | `major` | `nonsemver`), `current`, `latest`,
`group`, `is_pinned`, and `kind`. `total_count` is the genuine-upgrade count;
`actionable_count` is for the statusline only (it already subtracts local
snoozes), ignore it here.

`snoozed[]` lists the groups the human deferred earlier that still match the
currently-offered targets. Each entry carries `group`, `targets`, `snoozed_at`,
and `resurfaces_at` (ISO stamp when the snooze lapses). Build `snoozedGroups`,
the set of their `group` ids, this is what you mark and default-skip below. It
is empty in CI and whenever no active snooze matches the current offer.

`skipped[]` entries with `reason: "held"` are packages capped by the committed
`gaia.updateDepsHold` map in package.json (a durable version ceiling, distinct
from a snooze: it holds in CI too and never lapses until the maintainer lifts
it). They are already excluded from both waves, never installed, so nothing to
apply. Surface them once (see Preview) so the maintainer remembers a hold is
active.

A hold caps only the package it names; a coupled sibling in the same companion
group (e.g. `@vitejs/plugin-react` beside a held `vite`) still updates on its own
line. If a sibling release's peer range demands a version above the ceiling, hold
the sibling too by adding it to the map. The quality gate catches a peer conflict
before merge regardless.

**In CI (`CI=true`) or with `--scope <group>`, skip the preview and decision
entirely.** The apply set is the full payload (CI) or the named group
(`--scope`); jump straight to the apply phases with an empty skip set and no
ledger write.

### Preview

Group the entries for display into four sections in this order: **Major**,
**Non-semver**, **Minor**, **Patch**. A companion group (any `group` not prefixed
`singleton:`) renders as ONE block under the section of its most-severe member
(severity major > nonsemver > minor > patch) and is a single choice that updates
together. Render each row as `name  current → next`; for a companion group, list
its members under one labelled block (e.g. "react-router group, updates
together").

Mark every group in `snoozedGroups` with a trailing `[snoozed until <date>]`
(the entry's `resurfaces_at`, rendered as a plain date). Snoozed groups are
**default-skipped**: they are excluded from the default apply set, so a group the
human already deferred is not silently re-applied each run. The human can still
choose to refresh them.

If `skipped[]` has any `reason: "held"` entries, print one line above the
sections listing them, e.g. `Held by config (not offered): vite (current
8.0.16, ceiling 8.0)`. This is informational, held packages are never part of
any apply set; the line just keeps the active holds visible.

If `update_deps.mode` in `.gaia/automation.json` is `ci`, first print one line:
`CI owns updates; snoozing here only quiets your local statusline.`

Then ask with `AskUserQuestion` (single-select). **When `snoozedGroups` is
non-empty**, offer these options in this order:

- **Update the rest** (default, first option): apply every group EXCEPT the
  snoozed ones; leave the snoozes intact.
- **Choose what to skip**: the human names further package or group names to
  skip; the snoozed groups stay skipped too.
- **Update everything incl. snoozed**: apply every group AND clear the snoozes.
- **Cancel**: exit now, no branch, no changes, no ledger write.

**When `snoozedGroups` is empty**, offer the original three:

- **Update all** (default, first option): apply every group.
- **Choose what to skip**: the human names the package or group names to skip;
  everything else applies.
- **Cancel**: exit now, no branch, no changes, no ledger write.

### Decision

The **skip set** is `snoozedGroups` plus whatever the human names; the **apply
set** is every remaining group. The ledger is full-replace, so any `decline
--skip` call must name every group that should stay snoozed (the pre-existing
snoozes AND any newly named), or the omitted ones are dropped from the ledger.

- **Update the rest** (snoozed groups present) → apply set = payload minus
  `snoozedGroups`. Leave the ledger untouched (the snoozes already match the
  current targets), no `decline` call. **If the apply set is empty** (every
  outstanding group is snoozed), print
  `Snoozed N group(s); nothing else to update.` and exit (no branch).
- **Update all** (no snoozed groups) → clear any prior snoozes, apply
  everything:
  ```bash
  .gaia/cli/gaia update-deps decline --clear
  ```
  Apply set = the full payload.
- **Update everything incl. snoozed** → same action as Update all: clear the
  snoozes (`decline --clear`) and apply the full payload.
- **Choose what to skip** → collect the names, union with `snoozedGroups`, then
  record the whole skip set:
  ```bash
  .gaia/cli/gaia update-deps decline --source "$updates_json" --skip "<snoozed…,named…>"
  ```
  Each name expands to its whole companion group (a partial group cannot be
  skipped); an unknown name errors so you can re-ask. Apply set = the payload
  minus the skip set. Echo the resulting apply set back for confirmation.
  **If the apply set is now empty** (everything is skipped), print
  `Snoozed N group(s); nothing else to update.` and exit (no branch).
- **Cancel** → stop here.

The snooze ledger (`.gaia/local/declined-updates.json`) is local-only and
gitignored: it suppresses the statusline nudge and default-skips the group in
this preview until a newer version ships or 14 days pass. It never HARD-gates a
run, the human can always choose to refresh a snoozed group, and CI ignores it
entirely (CI is the freshness backstop and keeps opening PRs).

Carry the **apply set** (filtered `wave_a` and `wave_b`) into the phases below.

## Override audit + Wave A: Haiku agent

Spawn a **Haiku agent** (`model: "haiku"`) to run the override audit and the
Wave A batch install on the **apply set** computed above. Pass it these
instructions verbatim, substituting the apply set's Wave A entries into the
Wave A input:

---

### Phase 0: Override audit

Each key in the top-level `overrides:` map in `pnpm-workspace.yaml` exists for one of two reasons: to resolve a **peer-dependency conflict**, or to enforce a **security floor** (pin a transitive dependency at or above a patched version to clear a known advisory). The two are detected by different tests, and an override is obsolete only when removing it regresses **neither**. A peer-dep test alone is blind to security-floor pins (a CVE pin never produces a peer-dep error), so it would wrongly delete every one of them. (pnpm 11 reads overrides here; the `package.json` `pnpm.overrides` field is no longer honored.)

**Capture the advisory baseline first**, with every override still in place:

```bash
pnpm audit --json 2>/dev/null > /tmp/audit-baseline.json
jq -r '.advisories // {} | keys[]?' /tmp/audit-baseline.json | sort -u > /tmp/audit-baseline.txt
```

Each `.advisories` key is one advisory ID; `audit-baseline.txt` is the set of advisories the current overrides tolerate, and `audit-baseline.json` keeps the full records the classification below reads. (If a future pnpm emits the `vulnerabilities` shape instead of `advisories`, read whichever key is present, the goal is a stable ID set to diff against.)

**Classify each override against the baseline before toggling.** The toggle test below flags only advisories a removal *introduces*, so it cannot see a stale floor: a pin whose own release has since picked up an advisory already has that advisory in the baseline. Removing it either reintroduces the original advisory, so the pin is retained and stays stale, or introduces nothing new, so it is removed. Neither outcome says the pin needs raising. So, for each override key:

1. Take the key's **target package**: its last `>` segment, minus any trailing `@<range>` selector (a scoped name keeps its leading `@`). `js-yaml@^4.0.0` targets `js-yaml`; `parent>child` targets `child`.
2. When the key's value is an exact version, look for baseline advisories on the target package that list that version among their findings. `pnpm audit` reports only installed versions inside an advisory's `vulnerable_versions`, so a match means the pinned release is itself vulnerable:

   ```bash
   jq -r --arg pkg "<target package>" --arg ver "<pinned version>" '
     .advisories // {} | .[]
     | select(.module_name == $pkg and any(.findings[]?; .version == $ver))
     | "\(.id) \(.severity) patched: \(.patched_versions)"' /tmp/audit-baseline.json
   ```

   A value that is not an exact version (a range, or a `$` reference) cannot be matched this way. Skip it here and note it as **unchecked**, naming beside it any baseline advisory on its target package, so the maintainer judges it.
3. A match means the floor is **stale**. Re-floor it, the Bump remedy in `wiki/dependencies/pnpm-audit.md`: set the value to the lowest published version the advisory's `patched_versions` admits above the current pin, taking the highest such version when several advisories match. When `patched_versions` admits nothing (`<0.0.0`, no patched release exists), leave the pin and note it as **stale (no patch)**.

Once every stale key is re-floored, run `pnpm dedupe` once to apply the new pins, then recapture both baseline files with the command above, so the toggle loop diffs against the corrected tree. If that `pnpm dedupe` exits non-zero, restore the old pins, note each as **stale (re-floor failed)**, and continue with the original baseline. Note each applied key as **re-floored**, with its old pin, its new pin, and the advisory IDs. A re-floored key still runs through the toggle loop below like every other key, so its report line carries both verdicts (re-floored, then retained or removed); a re-floored key the loop removes means the patched release now arrives without the pin.

Then, for each override key, one at a time, leaving every other `pnpm-workspace.yaml` setting untouched:

1. Temporarily remove that single key from the `overrides:` map.
2. Run `pnpm dedupe`. A bare `pnpm install`, even `pnpm install --force`, short-circuits with "Already up to date" when only the `overrides:` map changed and leaves the lockfile untouched, so the toggle would not re-resolve and the test below would read the stale tree; `pnpm dedupe` performs a full install that re-resolves and applies the override change. See `wiki/dependencies/pnpm-overrides.md`. If it exits non-zero, restore the key, note as **retained (install error)**, and move to the next key, do not diagnose the failure or run the tests below for this key.
3. **Peer-dep test:** run `pnpm ls 2>&1` and scan for peer-dep errors.
4. **Security-floor test:** run `pnpm audit --json` and extract its advisory IDs the same way. Any ID present now but absent from `/tmp/audit-baseline.txt` means removing this override reintroduced a known vulnerability.

   ```bash
   pnpm audit --json 2>/dev/null | jq -r '.advisories // {} | keys[]?' | sort -u > /tmp/audit-now.txt
   comm -13 /tmp/audit-baseline.txt /tmp/audit-now.txt   # IDs this removal introduced
   ```

5. Decide:
   - Peer-dep errors **or** any newly introduced advisory → the override is load-bearing. Restore the key. Note as **retained** (record which test failed, and the advisory ID + package if it was the security-floor test).
   - Neither regressed → the override is obsolete. Leave it removed. Note as **removed**.

The security-floor test is **severity-agnostic on purpose**: an override is a deliberate maintainer artifact, so any advisory it was silencing, at any severity, is reason to keep it. This is intentionally stricter than the high/critical surfacing floor in the Noise scoping section of `wiki/dependencies/pnpm-audit.md`: deciding whether to *delete a maintainer's pin* warrants more caution than deciding whether to *surface* an advisory for review. A maintainer who wants a pin gone removes it by hand. The stale-floor classification is severity-agnostic for the same reason: a pin that no longer clears its own package's advisories is wrong at any severity.

**After the toggle loop, assert the lockfile matches config.** Once every retained key is restored, the lockfile's top-level `overrides:` block must list exactly the keys present in the `overrides:` map in `pnpm-workspace.yaml`. Compare the two; on any drift (a config key missing from the lockfile block, or vice versa) the floor is unapplied, so run `pnpm dedupe` once more and re-run the quality gate. This assertion guarantees that every retained floor is applied, never silently disabled. It says nothing about whether a floor is current; the stale-floor classification before the toggle loop owns that. Note the tradeoff: `pnpm dedupe` re-optimizes the whole tree, so a single toggle can yield a wider lockfile diff than the one key it touched (it may also drop now-redundant transitives). That broader diff is expected, and correct, the alternative is an unapplied override.

### Wave A input

You are given the **Wave A apply set**: the `wave_a` entries from the
orchestrator's discovery, minus any group the human chose to skip. Each entry
carries `name`, `current`, `latest`, `is_pinned`, and `kind` (`minor` or
`patch`). Do **not** run `pnpm outdated` or re-discover, the ESLint 9.x cap, the
release-age cooldown, and companion-group expansion are already applied. If the
Wave A apply set is empty, skip straight to the quality gate (Wave B groups, if
any, are handled by the orchestrator).

### Wave A (batch minor/patch)

1. Build install args. For each entry: if `is_pinned` use the exact target, else use `^<latest>`. Example: `pnpm add foo@1.2.3 bar@^4.5.0 ...`.
2. Run the single `pnpm add` command.
3. Run `pnpm ls 2>&1`. Scan for peer-dep errors.
4. On error: try one targeted fix in the `overrides:` map in `pnpm-workspace.yaml` (e.g. add a `parent>child` pin), then `pnpm dedupe` to apply it, a bare `pnpm install` won't re-resolve an overrides-only change.
5. If still failing: revert the offending packages (`pnpm add <pkg>@<previous>`) and log them as **skipped** with the reason.
6. Run the quality gate (below). If it fails, revert the entire Wave A batch.

### Quality gate

```bash
pnpm typecheck
pnpm lint
pnpm test --run
pnpm pw
pnpm build
```

### Return value

Report back to the orchestrator with:

- Override audit results (removed / retained, each re-floored key, and each stale or unchecked key left for the maintainer)
- Wave A results (updated packages, any skipped)
- Quality gate results

---

## Branch creation (after discovery)

Phase 1 already exited if nothing was outstanding or the human cancelled or
skipped everything, so reaching here means the apply set is non-empty. After the
Haiku agent returns:

- Updates were confirmed. **Immediately bust the update-check cache** so the statusline reflects the post-update state on the next session regardless of whether this run completes. Use the Write tool to overwrite `.gaia/local/cache/shared/update-check.json`: read the existing cache first, then write it back unchanged **except** `outdatedCount` set to `0` and `checkedAt` set to the current Unix timestamp. **Carry every other field across verbatim, named here or not.** The cache holds fields this step has no reason to know about, and several are observations nothing later can reconstruct (`auditDriftBaseline`, `auditMemoryBaseline`, and the two `harden*` counts), so dropping one silently disarms the nudge it belongs to instead of causing a visible error. If the cache file does not exist, skip this step. (Snoozed groups are already excluded by the ledger on the next real check.)

- If `SHOULD_CREATE_BRANCH=true`, create the branch now and **remember that you created it** (this determines publish behavior in Phase 8):

```bash
git checkout -b "$(bash .gaia/scripts/branch-name-lib.sh name chore update-deps)"
# CREATED_NEW_BRANCH=true, used in Phase 8
```

Otherwise (`SHOULD_CREATE_BRANCH=false`), proceed on the current branch and **remember that you did NOT create a new branch**.

## Phase 5: Wave B (per-group major bumps)

Use the **Wave B groups from the apply set** (the payload's `wave_b` minus any
group the human skipped). If there are none, skip to Phase 6.

For each Wave B group, classify complexity and assign a model:

**Opus** (`model: "opus"`): `react-router`, `react`, `storybook`,
`singleton:typescript`

**Sonnet** (`model: "sonnet"`): `eslint`, all other groups

Spawn one agent per group (or sequentially if resource-constrained), passing it these instructions:

---

### Wave B group instructions

You are upgrading the `{GROUP}` dependency group from `{FROM}` to `{TO}`.

**Scope.** Operate on the **root pnpm project only**.

- Run every `pnpm` command from the project root. Never `cd` into subdirectories or use `-C <path>`.
- For code edits and grep-style searches, scan only `app/`, `test/`, and root config files (`*.config.*`, `tsconfig*.json` at root). Do **not** scan the entire repository, sibling directories may be independent pnpm projects with their own `package.json`/`pnpm-lock.yaml`, and they are out of scope for this skill.
- A directory is "out of scope" if it contains its own `package.json` or `pnpm-lock.yaml`. Skip those subtrees entirely.

1. **Fetch migration guide** via WebFetch using the table below. If no URL applies, scan the GitHub release notes.
2. **Install** the group, **from project root only**:
   - `storybook` group: run `pnpm dlx storybook@latest upgrade` (Storybook's own upgrade tool migrates config alongside the version bump).
   - All others: `pnpm add <pkg1>@<latest> <pkg2>@<latest> ...` for every group member present in root `package.json`.
3. **Conflict check**: `pnpm ls 2>&1`. On peer-dep error, attempt one `overrides:` fix in `pnpm-workspace.yaml`, then `pnpm dedupe` to apply it, a bare `pnpm install` won't re-resolve an overrides-only change. If still failing, revert the group and skip with reason.
4. **Apply breaking changes** within root scope: from the migration guide, identify code-affecting changes (renamed APIs, removed exports, config schema changes). Grep `app/`, `test/`, and root config files for affected patterns. Edit only files inside root scope.
5. **Verify root `package.json` moved**: read root `package.json` and confirm every group member you bumped now shows the new version. If `pnpm add` did not change root's spec (e.g. the dep is declared in a sibling project's `package.json` and not actually consumed by root code), revert the install and report the package as **skipped, not a root dep**. The skill does not resolve cross-project declarations; the maintainer must clean up manually. If the dep is in root `package.json` but has zero call sites in root scope, that's a phantom declaration: bump it anyway so the version stays current, and add a one-line note `phantom: no call sites in root` to the breaking-changes report so the maintainer can investigate.
6. **Quality gate**:
   ```bash
   pnpm typecheck
   pnpm lint
   pnpm test --run
   pnpm pw
   pnpm build
   ```
   On failure, make one remediation pass: apply fixes inferred from the migration guide, then re-run the gate once. If it still fails after that single re-run, revert the entire group and log as skipped. Do not keep iterating.

## Phase 6: Post-update override audit

For every override that was **retained** in Phase 0, repeat the full Phase 0 audit (the stale-floor classification, then both the peer-dep and the security-floor check, re-capturing a fresh advisory baseline against the now-updated tree) now that surrounding packages have moved. A version that landed in Wave A or Wave B may have resolved the original peer-dep conflict or carried the patched transitive dependency that made a security-floor pin obsolete. The toggle test re-resolves with `pnpm dedupe`, never a bare `pnpm install`, exactly as in Phase 0. This is the last phase that mutates the `overrides:` map, so the lockfile settles here: close it with the same assertion Phase 0 runs, the lockfile's `overrides:` block must list exactly the keys in `pnpm-workspace.yaml`, repairing any drift with `pnpm dedupe`.

Run this as a **Haiku agent**. Its dispatch carries every Phase 6 duty, so pass it all four of these:

- **The recipe.** The Phase 0 section and the Quality gate subsection above verbatim, restricted to the keys retained in Phase 0, so every quality-gate run it owes runs those same commands.
- **When to gate.** Run the quality gate once, after the lockfile assertion, whenever it re-floored or removed any key or repaired lockfile drift. No Wave agent gated that change. This replaces the drift-only trigger in the Phase 0 section.
- **On a failed gate.** Restore every key it re-floored or removed to the value it held when this Phase 6 run began, run `pnpm dedupe` to apply the restore, and re-run the lockfile assertion. This is the counterpart of Wave A reverting its whole batch: one gate run cannot say which key broke it, so the restore takes them all. Report each restored removal as **retained (quality gate failed)** and each restored re-floor as **stale (re-floor failed)**. When it changed no key and the gate ran only for a drift repair, there is nothing to restore: report the failure for the maintainer to resolve.
- **What to return.** The override audit results (removed / retained, each re-floored key, and each stale or unchecked key left for the maintainer) and the quality gate results, including a failed gate and whatever restore followed it, so the Phase 7 Quality gate section has the Phase 6 run to report.

<!-- gaia:maintainer-only:start -->
## Phase 6b: `.gaia/cli` pin sync (GAIA maintainer repository)

`.gaia/cli` is a second workspace root with its own `package.json` and lockfile. `.gaia/cli/src/lint-pin-parity.test.ts` requires it to pin every devDependency it shares with the root at the root's version, except the keys of `MANIFEST_PARITY_EXEMPT` in that file. The phases above bump the root alone, so a run that moves a shared pin leaves the required `Vitest (.gaia/cli)` check red. Run this phase inline, after Phase 6 and before the report:

1. For each devDependency declared in both root `package.json` and `.gaia/cli/package.json`, that is not a key of `MANIFEST_PARITY_EXEMPT`, and whose CLI spec differs from the root's, set the CLI spec to the root's verbatim. The direction is always CLI to root; never edit the root to match the CLI. Skip the rest of this phase only when nothing differs **and** the run left the root `pnpm-lock.yaml` unchanged: a root re-resolve can move a transitive version the pin-parity test compares without touching any pin.
2. Run `pnpm -C .gaia/cli install`, then `pnpm -C .gaia/cli lint`, `pnpm -C .gaia/cli typecheck`, and `pnpm -C .gaia/cli test`. The pin-parity test also compares the versions both lockfiles resolve for a few transitive rule packages, which neither the pin edit nor the install repairs. When that half fails, follow the header's Repair paragraph for the lockfile parity test (re-resolve the lagging workspace with `pnpm update <package>`) rather than adding a pin.
3. Run `pnpm -C .gaia/cli bundle`, then `bash .gaia/scripts/verify-cli-bundle-fresh.sh` from the repository root. Phase 8's `git add -A` commits any bundle that moved.
4. Add a `.gaia/cli pin sync` row to the report's Quality gate table naming each raised pin (`<name>: <old> → <new>`) and the step 2 and 3 results. On a failure, keep the raised pins, since reverting them guarantees the red check this phase exists to prevent, and let the row carry the failure for the maintainer.

The raised pins put `.gaia/cli/package.json` and its lockfile in the diff, which dispatches `code-audit-maintainer-node`. On a run that started on `main`/`master`, Phase 8's merge step covers that dispatch; on any other run, the branch owner does.
<!-- gaia:maintainer-only:end -->

## Phase 7: Final report

Build the report **only** from the agent reports returned to you, plus the snooze decision from Phase 1. Do not add rows from your own memory of the run.

**What goes in each section:**

- **Updated packages**: every package the Haiku agent or a Wave B agent reports as `updated`. Nothing else.
- **Breaking changes applied**: only what Wave B agents report editing in the codebase. Empty if no Wave B group ran.
- **Overrides audited**: only what the Phase 0 / Phase 6 audit reports. If the `overrides:` map was empty, write "None" and move on.
- **Skipped packages**: _only_ packages that were attempted and reverted mid-run (peer-dep conflict, quality-gate failure, manual revert by an agent). **Never** include packages filtered out before installation by a policy rule (e.g. the ESLint 9.x cap or the release-age cooldown). Those are silent by design, surfacing them is noise that adopters see every run. When you cannot tell whether a package was policy-filtered before installation or attempted and reverted mid-run, include it in Skipped, a spurious row is recoverable but a silently dropped real failure is not. If nothing was actually skipped during the run, write "None" or omit the table.
- **Snoozed (deferred this run)**: the companion groups the human chose to skip in the preview, with the version each was snoozed at. These quiet the statusline for 14 days (or until a newer version ships); they are not failures. Omit the section if the human chose "Update all".
- **Quality gate**: the gate result reported by the agents, verbatim.
<!-- gaia:maintainer-only:start -->
- **Phase 6b**: runs inline rather than as an agent, so its `.gaia/cli pin sync` row is the one exception to building the report only from agent reports. Include it whenever Phase 6b ran past step 1, including a failed step it kept in the diff.
<!-- gaia:maintainer-only:end -->

If a section would be empty, write "None" rather than leaving it blank or fabricating filler.

Print the report. Do not commit.

## Phase 8: Publish

**If nothing was updated** (all packages were already up to date or all were skipped), skip this phase entirely.

**Commit the update.** Stage and commit the applied changes on the current branch. Write the message to a temp file first, then commit from it:

```bash
git add -A
git commit -F <commit-message-file>
```

The commit **subject** must be `chore(deps): <concise summary of what moved>` (use `chore(deps-dev):` when every bump is a devDependency). That subject is load-bearing: it triggers the dep-bump bypass in the merge gate (`wiki/concepts/PR Merge Workflow.md`), so the PR needs no code-audit-frontend marker. The bypass waives that member only; any other member the diff dispatches still earns its own marker. Routing the message through a file rather than `-m` keeps package-manager keywords from tripping shell-hook false positives. The Wave agents already ran the full quality gate over their changes, and Phase 6 kept only the override changes that passed it, so nothing else is owed before committing. A Phase 6 gate failure with nothing to restore is already in the report's Quality gate section for the maintainer.
<!-- gaia:maintainer-only:start -->
A Phase 6b failure is the exception: it keeps its raised pins and reports through its `.gaia/cli pin sync` row, so the required `Vitest (.gaia/cli)` check stays red and step 3's queued merge waits on the maintainer rather than landing.
<!-- gaia:maintainer-only:end -->

Then branch on where the run started.

**If a new branch was created** (interactive run, you were on `main`/`master` at pre-flight and branched off):

1. Push the branch:
   ```bash
   git push -u origin <branch-name>
   ```
2. Open a PR against `main`. Title: the commit subject. Body: the migration report rendered as markdown, via `--body-file` on a temp file (same false-positive reason). Capture the PR number `<N>` and its URL.
3. **Merge when green, then clean up locally.** This step runs only on a `main`/`master` run, it is what "completes the flow." Merge per `wiki/concepts/PR Merge Workflow.md` (the `chore(deps)` title clears its audit-marker gate via the dep-bump bypass):
<!-- gaia:maintainer-only:start -->
   First, run `bash .gaia/scripts/resolve-audit-spawn.sh` and spawn each member it names other than `code-audit-frontend`, per that workflow page's "Spawn the dispatched Code Audit Team members" section. Whenever Phase 6b raised a pin, `code-audit-maintainer-node` is among them. The `chore(deps)` title waives only `code-audit-frontend` (see the bypass paragraph in `wiki/concepts/PR Merge Workflow.md`), so each other member's earned marker is what completes the handshake. Skip this and `GAIA-Audit` stays at `members pending` and the queued merge waits on it indefinitely. Members write their markers only, they do not post the success status themselves; once `wiki/concepts/PR Merge Workflow.md` `#### Posting the status last` conditions hold, post it yourself, `bash .claude/hooks/post-audit-status.sh <path to a current member marker>`, before the merge call below.
<!-- gaia:maintainer-only:end -->
   ```bash
   gh pr merge <N> --squash --delete-branch --auto
   ```
   `--auto` queues the merge so GitHub lands it once the required checks pass (or immediately if they are already green). If the repo has auto-merge disabled and `gh` rejects `--auto`, wait for the required checks to pass (`gh pr checks <N>`), then re-run the merge without `--auto`.

   `gh pr merge` can exit success while the merge is still queued, so verify the terminal state before touching the local checkout with the bounded poll in `wiki/concepts/PR Merge Workflow.md` (`## Post-merge verification before cleanup`), which also stops early on a base-branch conflict or a failed required check.
   - **`state == MERGED`** → clean up locally, then print the merged PR URL:
     ```bash
     git checkout main && git pull origin main
     git branch -D <branch-name>
     git fetch --prune origin
     ```
   - **still not `MERGED`** (auto-merge queued, checks not yet green) → print the
