Kjell Tore Guttormsen acd1cf1248 fix(commands): stop writing files no later step can read, and payloads nobody asked for
Dogfooding the four read commands (posture, tokens, manifest, whats-active)
surfaced four defect classes, all in the seam between what a command template
promises and what the scanner behind it actually does.

M-BUG-40, fifth arm: posture wrote four temp files it could never read back.
#49 closed the $$/cross-block class in four commands, but posture survived it —
and so did the guard written to prevent exactly this. The guard compared each
$$ path to the block that created it, so a path written once and then read via
prose had no second occurrence to flag. Measured live: written from PID 21614,
read attempted from PID 23772. The invariant is now blanket (no $$ in any temp
path), which also caught fix.md and feature-gap.md.

M-BUG-43: 6 of 7 scanners write their payload to stdout when --raw/--json is
set even when --output-file was given, and the templates redirected only
stderr. Measured: posture 255 182 B, whats-active 35 922 B, drift 28 316 B,
manifest 23 825 B, tokens 8 768 B. fix and feature-gap never read the file they
wrote, so both recovered one letter grade from a quarter-megabyte dump.

tokens swallowed --json and --with-telemetry-recipe: documented, never
threaded, so --json returned the humanized payload where the docs promise
byte-stable v5.0.0 output.

M-BUG-42: manifest's render contract asked for {load}; the payload carries
loadPattern, so the Load column rendered blank for all 96 rows.

Four new tests (1449 -> 1453), each verified red before the fix. The
render-contract test checks {field} names against a live payload from a
fixture, since a hardcoded key list would drift. Frozen v5.0.0 snapshots
untouched.

# Config-Audit: Fix
Auto-fix deterministic configuration issues. Scans, plans fixes, backs up originals, applies changes, and verifies results.
## Arguments
- `$ARGUMENTS` may contain:
- A target path (default: current working directory)
- `--dry-run`: Show fix plan without applying
- `--global`: Include user-scope config (`~/.claude`) in the scan **and** the fix run
- `--raw`: Pass-through to scanners; produces v5.0.0 verbatim envelope (bypasses the humanizer) for byte-stable diff tooling
`--global` must be passed to **every** step below. The scan that builds the table and
the scan that plans the fixes are two different runs; if only one of them sees the
user scope, the plan and the table describe different config.
## Implementation
### Step 1: Greet and scan
Tell the user:
```
## Config-Audit Fix
Scanning for auto-fixable issues...
```
Parse flags and run scanners silently. Default mode emits humanized JSON — each finding carries `userImpactCategory`, `userActionLanguage`, and `relevanceContext` alongside the v5.0.0 fields:
```bash
RAW_FLAG=""
if echo "$ARGUMENTS" | grep -q -- "--raw"; then RAW_FLAG="--raw"; fi
# Set to --global when the user asked for global scope, otherwise leave empty.
# A placeholder in square brackets does not start with a dash, so the arg loop
# would take it as the scan/fix TARGET instead of a flag.
GLOBAL_FLAG=""
node ${CLAUDE_PLUGIN_ROOT}/scanners/scan-orchestrator.mjs <path> --output-file /tmp/config-audit-fix-scan.json $GLOBAL_FLAG $RAW_FLAG >/dev/null 2>/dev/null; echo $?
```
Exit code 3 → tell user: "Scanner error. Try `/config-audit posture` to check your configuration."
### Step 2: Plan fixes
Run fix planner silently. The fix-cli emits humanized prose to stderr in default mode and v5.0.0-shape JSON to stdout when `--json` is set; we use `--json` here for structured data and let the humanizer-aware rendering layer (this command's prose output below) supply the plain-language wording from the scan envelope above:
```bash
# Re-assign here: each fenced block is its own Bash call, so the value
# set in Step 1 is empty by the time this block runs.
GLOBAL_FLAG="" # --global when the user asked for global scope
node ${CLAUDE_PLUGIN_ROOT}/scanners/fix-cli.mjs <path> $GLOBAL_FLAG --output-file /tmp/config-audit-fix-plan.json 2>/dev/null; echo $?
```
Exit codes: 0 = plan produced, 2 = one or more fixes failed (apply step only), 3 = argument or tool error. On 3, show the stderr message — an unknown flag is rejected by design, not silently ignored.
Read `/tmp/config-audit-fix-plan.json` using the Read tool. Cross-reference each fix-plan entry against the humanized scan envelope (`/tmp/config-audit-fix-scan.json`) by finding ID to recover the humanized `title`/`description`/`recommendation` plus `userImpactCategory`/`userActionLanguage` for grouping.
### Step 3: Present fix plan
Show what will be fixed and what needs manual attention. Group by `userActionLanguage` so the urgency phrasing stays consistent with the rest of the toolchain:
```markdown
### Fix Plan
**Auto-fixable ({N} issues), grouped by impact:**
{For each userActionLanguage bucket in priority order — "Fix this now" → "Fix soon" → "Fix when convenient" → "Optional cleanup" → "FYI":}
#### {userActionLanguage}
| # | ID | Issue | File |
|---|-----|-------|------|
| 1 | {id} | {humanized title} | {file} |
**Manual ({M} issues — require human judgment), grouped by impact:**
{Same userActionLanguage grouping. Render humanized title and recommendation verbatim — the humanizer already produced plain-language strings, do not paraphrase.}
| # | ID | Issue | Recommendation |
|---|-----|-------|----------------|
| 1 | {id} | {humanized title} | {humanized recommendation} |
```
### Step 4: Confirm with user
If not `--dry-run`, ask for confirmation:
```
AskUserQuestion:
question: "Apply {N} auto-fixes? A backup is created first — you can roll back anytime."
options:
- "Yes, apply fixes"
- "Show dry-run only"
- "Cancel"
```
### Step 5: Apply fixes
If confirmed, apply:
```bash
# Re-assign here: each fenced block is its own Bash call, so the value
# set in Step 1 is empty by the time this block runs.
GLOBAL_FLAG="" # --global when the user asked for global scope
node ${CLAUDE_PLUGIN_ROOT}/scanners/fix-cli.mjs <path> --apply $GLOBAL_FLAG --output-file /tmp/config-audit-fix-applied.json 2>/dev/null; echo $?
```
Read `/tmp/config-audit-fix-applied.json` with the Read tool to get applied/failed counts and the backup ID. Exit code 2 means at least one fix failed — report it; `failed[]` carries the reason per fix.
### Step 6: Show results
Run a quick posture check to measure improvement:
```bash
node ${CLAUDE_PLUGIN_ROOT}/scanners/posture.mjs <path> --json --output-file /tmp/config-audit-fix-posture.json >/dev/null 2>/dev/null
```
Use the Read tool on `/tmp/config-audit-fix-posture.json` and take `overallGrade`
and the score from there. That read is the only source for the numbers below:
`--json` prints the same envelope to stdout, but 255 KB of raw JSON in the
transcript to recover one grade is exactly the waste this plugin exists to find.
Present results:
```markdown
### Results
**{applied} fixed** | {failed} failed | Backup created
{If grade improved:}
Score impact: {old_grade} ({old_score}) → {new_grade} ({new_score}) — **+{delta} points**
{If failed > 0:}
{failed} fix(es) couldn't be applied — run `/config-audit plan` for alternative approaches.
**Rollback:** If anything looks wrong, run `/config-audit rollback {backup-id}` to restore.
```
### Step 7: Manual findings
If manual findings exist:
```markdown
### Needs manual attention
These {M} issues require human judgment:
1. **{title}** ({id}) — {recommendation}
2. ...
Run `/config-audit plan` to get a step-by-step guide for addressing these.
```
## Safety
- Backup is **mandatory** — every fix creates a backup first, including file renames (the source file is backed up before the rename, so rollback can restore it at its original path)
- Dry-run by default — user must confirm before changes
- Verify after fix — re-scans in the **same scope** the fix run used, so a `--global` run is verified against user scope too
- Rollback always available — `/config-audit rollback <backup-id>`
- A failed fix is reported, never swallowed — exit 2 plus a `failed[]` entry
