Signal Banner Redesign — Expandable Email + Re-classification Implementation Plan
For agentic workers: REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (
- [ ]) syntax for tracking.
Goal: Expand signal banners to show full email body, add inline re-classification chips, and remove single-click stage advancement (always route through MoveToSheet).
Architecture: Backend adds body/from_addr to the signal query and a new POST /api/stage-signals/{id}/reclassify endpoint. The StageSignal TypeScript interface gains two nullable fields. Both InterviewCard.vue (kanban) and InterviewsView.vue (pre-list) get an expand toggle, body display, and six re-classification chips. Optimistic local mutation drives reactive re-labeling; neutral triggers a two-call dismiss path to preserve Avocet training signal.
Tech Stack: FastAPI (Python), SQLite, Vue 3, TypeScript, Pinia, useApiFetch composable
Spec: docs/superpowers/specs/2026-03-19-signal-banner-reclassify-design.md

Task 1: Backend — body/from_addr fields + reclassify endpoint
Files:
- Modify:
dev-api.py(lines ~309–325 signal SELECT + append block; after line 388 for new endpoint) - Modify:
tests/test_dev_api_interviews.py(fixture schema + 4 test changes)
Step 1.1: Write the four failing tests
Add to tests/test_dev_api_interviews.py:
# ── Body/from_addr in signal response ─────────────────────────────────────
def test_interviews_signal_includes_body_and_from_addr(client):
resp = client.get("/api/interviews")
assert resp.status_code == 200
jobs = {j["id"]: j for j in resp.json()}
sig = jobs[1]["stage_signals"][0]
# Fields must exist (may be None when DB column is NULL)
assert "body" in sig
assert "from_addr" in sig
# ── POST /api/stage-signals/{id}/reclassify ────────────────────────────────
def test_reclassify_signal_updates_label(client, tmp_db):
resp = client.post("/api/stage-signals/10/reclassify",
json={"stage_signal": "positive_response"})
assert resp.status_code == 200
assert resp.json() == {"ok": True}
con = sqlite3.connect(tmp_db)
row = con.execute(
"SELECT stage_signal FROM job_contacts WHERE id = 10"
).fetchone()
con.close()
assert row[0] == "positive_response"
def test_reclassify_signal_invalid_label(client):
resp = client.post("/api/stage-signals/10/reclassify",
json={"stage_signal": "not_a_real_label"})
assert resp.status_code == 400
def test_reclassify_signal_404_for_missing_id(client):
resp = client.post("/api/stage-signals/9999/reclassify",
json={"stage_signal": "neutral"})
assert resp.status_code == 404
- Add the four test functions above to
tests/test_dev_api_interviews.py
Step 1.2: Also extend test_interviews_includes_stage_signals to assert body/from_addr
The existing test (line 64) asserts id, stage_signal, and subject. Add assertions for the two new fields after the existing assert signals[0]["id"] == 10 line:
assert "body" in signals[0]
assert "from_addr" in signals[0]
- Add those two lines inside
test_interviews_includes_stage_signals, afterassert signals[0]["id"] == 10
Step 1.3: Update the fixture to include body and from_addr columns
The job_contacts CREATE TABLE in the tmp_db fixture is missing body TEXT and from_addr TEXT. The fixture test-side schema must match the real DB.
Replace the job_contacts CREATE TABLE block (currently id, job_id, subject, received_at, stage_signal, suggestion_dismissed) with:
CREATE TABLE job_contacts (
id INTEGER PRIMARY KEY,
job_id INTEGER,
subject TEXT,
received_at TEXT,
stage_signal TEXT,
suggestion_dismissed INTEGER DEFAULT 0,
body TEXT,
from_addr TEXT
);
- Update the
tmp_dbfixture'sjob_contactsschema to addbody TEXTandfrom_addr TEXT
Step 1.4: Run tests to confirm they all fail as expected
cd /Library/Development/CircuitForge/peregrine/.worktrees/feature-vue-spa
/devl/miniconda3/envs/job-seeker/bin/pytest tests/test_dev_api_interviews.py -v
Expected: 5 new/modified tests FAIL (body/from_addr not in response; reclassify endpoint 404s); existing 8 tests still PASS.
- Run and confirm
Step 1.5: Update dev-api.py — add body/from_addr to signal SELECT and append
Find the signal SELECT query (line ~309). Replace:
sig_rows = db.execute(
f"SELECT id, job_id, subject, received_at, stage_signal "
With:
sig_rows = db.execute(
f"SELECT id, job_id, subject, received_at, stage_signal, body, from_addr "
Then extend the signals_by_job append dict (line ~319). Replace:
signals_by_job[sr["job_id"]].append({
"id": sr["id"],
"subject": sr["subject"],
"received_at": sr["received_at"],
"stage_signal": sr["stage_signal"],
})
With:
signals_by_job[sr["job_id"]].append({
"id": sr["id"],
"subject": sr["subject"],
"received_at": sr["received_at"],
"stage_signal": sr["stage_signal"],
"body": sr["body"],
"from_addr": sr["from_addr"],
})
- Apply both edits to
dev-api.py
Step 1.6: Add the reclassify endpoint to dev-api.py
After the dismiss_signal endpoint (around line 388), add:
# ── POST /api/stage-signals/{id}/reclassify ──────────────────────────────
VALID_SIGNAL_LABELS = {
'interview_scheduled', 'offer_received', 'rejected',
'positive_response', 'survey_received', 'neutral',
'event_rescheduled', 'unrelated', 'digest',
}
class ReclassifyBody(BaseModel):
stage_signal: str
@app.post("/api/stage-signals/{signal_id}/reclassify")
def reclassify_signal(signal_id: int, body: ReclassifyBody):
if body.stage_signal not in VALID_SIGNAL_LABELS:
raise HTTPException(400, f"Invalid label: {body.stage_signal}")
db = _get_db()
result = db.execute(
"UPDATE job_contacts SET stage_signal = ? WHERE id = ?",
(body.stage_signal, signal_id),
)
rowcount = result.rowcount
db.commit()
db.close()
if rowcount == 0:
raise HTTPException(404, "Signal not found")
return {"ok": True}
Note: BaseModel is already imported via from pydantic import BaseModel at the top of the file — check before adding a duplicate import.
- Add the endpoint and
VALID_SIGNAL_LABELS/ReclassifyBodytodev-api.pyafter the dismiss endpoint
Step 1.7: Run the full test suite to verify all tests pass
/devl/miniconda3/envs/job-seeker/bin/pytest tests/test_dev_api_interviews.py -v
Expected: all tests PASS (13 total: 8 existing + 5 new/extended).
- Run and confirm
Step 1.8: Commit
cd /Library/Development/CircuitForge/peregrine/.worktrees/feature-vue-spa
git add dev-api.py tests/test_dev_api_interviews.py
git commit -m "feat(signals): add body/from_addr to signal query; add reclassify endpoint"
- Commit
Task 2: Store — add body/from_addr to StageSignal interface
Files:
- Modify:
web/src/stores/interviews.ts(lines 5–10,StageSignalinterface)
Why this is its own task: Both InterviewCard.vue and InterviewsView.vue import StageSignal. TypeScript will error on sig.body / sig.from_addr until the interface is updated. Committing the type change first keeps Tasks 3 and 4 independently compilable.
Step 2.1: Update StageSignal in web/src/stores/interviews.ts
Replace:
export interface StageSignal {
id: number // job_contacts.id — used for POST /api/stage-signals/{id}/dismiss
subject: string
received_at: string // ISO timestamp
stage_signal: 'interview_scheduled' | 'positive_response' | 'offer_received' | 'survey_received' | 'rejected'
}
With:
export interface StageSignal {
id: number // job_contacts.id — used for POST /api/stage-signals/{id}/dismiss
subject: string
received_at: string // ISO timestamp
stage_signal: 'interview_scheduled' | 'positive_response' | 'offer_received' | 'survey_received' | 'rejected'
body: string | null // email body text; null if not available
from_addr: string | null // sender address; null if not available
}
- Edit
web/src/stores/interviews.ts
Step 2.2: Verify TypeScript compiles cleanly
cd /Library/Development/CircuitForge/peregrine/.worktrees/feature-vue-spa/web
npx vue-tsc --noEmit
Expected: 0 errors (the new fields are nullable so no existing code should break).
- Run and confirm
Step 2.3: Commit
cd /Library/Development/CircuitForge/peregrine/.worktrees/feature-vue-spa
git add web/src/stores/interviews.ts
git commit -m "feat(signals): add body and from_addr to StageSignal interface"
- Commit
Task 3: InterviewCard.vue — expand toggle, body display, reclassify chips
Files:
- Modify:
web/src/components/InterviewCard.vue
Context: This component is the kanban card. It shows one signal by default, and a +N more button for additional signals. The bodyExpanded ref is per-card (not per-signal) because at most one signal is visible in collapsed state.
Step 3.1: Add bodyExpanded ref and reclassifySignal function
In the <script setup> section, after the dismissSignal function, add:
const bodyExpanded = ref(false)
// Re-classify chips — neutral triggers two-call dismiss path
const RECLASSIFY_CHIPS = [
{ label: '🟡 Interview', value: 'interview_scheduled' as const },
{ label: '✅ Positive', value: 'positive_response' as const },
{ label: '🟢 Offer', value: 'offer_received' as const },
{ label: '📋 Survey', value: 'survey_received' as const },
{ label: '✖ Rejected', value: 'rejected' as const },
{ label: '— Neutral', value: 'neutral' },
] as const
async function reclassifySignal(sig: StageSignal, newLabel: string) {
if (newLabel === 'neutral') {
// Optimistic removal — neutral signals are dismissed
const arr = props.job.stage_signals
const idx = arr.findIndex(s => s.id === sig.id)
if (idx !== -1) arr.splice(idx, 1)
// Two-call path: persist corrected label then dismiss (Avocet training hook)
await useApiFetch(`/api/stage-signals/${sig.id}/reclassify`, {
method: 'POST',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify({ stage_signal: 'neutral' }),
})
await useApiFetch(`/api/stage-signals/${sig.id}/dismiss`, { method: 'POST' })
} else {
// Optimistic local re-label — Vue 3 proxy tracks the mutation
sig.stage_signal = newLabel as StageSignal['stage_signal']
await useApiFetch(`/api/stage-signals/${sig.id}/reclassify`, {
method: 'POST',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify({ stage_signal: newLabel }),
})
}
}
- Add
bodyExpanded,RECLASSIFY_CHIPS, andreclassifySignalto the script section
Step 3.2: Update the signal banner template
Find the signal banner <template v-if="job.stage_signals?.length"> block (lines ~131–163). Replace the entire block with:
<!-- Signal banners -->
<template v-if="job.stage_signals?.length">
<div
v-for="sig in visibleSignals()"
:key="sig.id"
class="signal-banner"
:style="{
background: COLOR_BG[SIGNAL_META[sig.stage_signal].color],
borderTopColor: COLOR_BORDER[SIGNAL_META[sig.stage_signal].color],
}"
>
<div class="signal-header">
<span class="signal-label">
📧 <strong>{{ SIGNAL_META[sig.stage_signal].label.replace('Move to ', '') }}</strong>
</span>
<span class="signal-subject">{{ sig.subject.slice(0, 60) }}{{ sig.subject.length > 60 ? '…' : '' }}</span>
<div class="signal-header-actions">
<button class="btn-signal-read" @click.stop="bodyExpanded = !bodyExpanded">
{{ bodyExpanded ? '▾ Hide' : '▸ Read' }}
</button>
<button
class="btn-signal-move"
@click.stop="emit('move', props.job.id, SIGNAL_META[sig.stage_signal].stage)"
:aria-label="`${SIGNAL_META[sig.stage_signal].label} for ${props.job.title}`"
>→ Move</button>
<button
class="btn-signal-dismiss"
@click.stop="dismissSignal(sig)"
aria-label="Dismiss signal"
>✕</button>
</div>
</div>
<!-- Expanded body + reclassify chips -->
<div v-if="bodyExpanded" class="signal-body-expanded">
<div v-if="sig.from_addr" class="signal-from">From: {{ sig.from_addr }}</div>
<div v-if="sig.body" class="signal-body-text">{{ sig.body }}</div>
<div v-else class="signal-body-empty">No email body available.</div>
<div class="signal-reclassify">
<span class="signal-reclassify-label">Re-classify:</span>
<button
v-for="chip in RECLASSIFY_CHIPS"
:key="chip.value"
class="btn-chip"
:class="{ 'btn-chip-active': sig.stage_signal === chip.value }"
@click.stop="reclassifySignal(sig, chip.value)"
>{{ chip.label }}</button>
</div>
</div>
</div>
<button
v-if="(job.stage_signals?.length ?? 0) > 1"
class="btn-sig-expand"
@click.stop="sigExpanded = !sigExpanded"
>{{ sigExpanded ? '− less' : `+${(job.stage_signals?.length ?? 1) - 1} more` }}</button>
</template>
- Replace the signal banner template block
Step 3.3: Add CSS for new elements
After the existing .btn-signal-dismiss rule, add:
.btn-signal-read {
background: none; border: none; color: var(--color-text-muted); font-size: 0.82em;
cursor: pointer; padding: 2px 6px; white-space: nowrap;
}
.signal-header {
display: flex; align-items: center; gap: 8px; flex-wrap: wrap;
}
.signal-header-actions {
margin-left: auto; display: flex; gap: 6px; align-items: center;
}
.signal-body-expanded {
margin-top: 8px; font-size: 0.8em; border-top: 1px dashed var(--color-border);
padding-top: 8px;
}
.signal-from {
color: var(--color-text-muted); margin-bottom: 4px;
}
.signal-body-text {
white-space: pre-wrap; color: var(--color-text); line-height: 1.5;
max-height: 200px; overflow-y: auto;
}
.signal-body-empty {
color: var(--color-text-muted); font-style: italic;
}
.signal-reclassify {
display: flex; gap: 6px; flex-wrap: wrap; align-items: center; margin-top: 8px;
}
.signal-reclassify-label {
font-size: 0.75em; color: var(--color-text-muted);
}
.btn-chip {
background: var(--color-surface); color: var(--color-text-muted);
border: 1px solid var(--color-border); border-radius: 4px;
padding: 2px 7px; font-size: 0.75em; cursor: pointer;
}
.btn-chip:hover {
background: var(--color-hover);
}
.btn-chip-active {
background: var(--color-primary-muted, #e8f0ff);
color: var(--color-primary); border-color: var(--color-primary);
font-weight: 600;
}
- Add the CSS rules to the
<style>section ofInterviewCard.vue
Step 3.4: Verify TypeScript compiles cleanly
cd /Library/Development/CircuitForge/peregrine/.worktrees/feature-vue-spa/web
npx vue-tsc --noEmit
Expected: 0 errors.
- Run and confirm
Step 3.5: Commit
cd /Library/Development/CircuitForge/peregrine/.worktrees/feature-vue-spa
git add web/src/components/InterviewCard.vue
git commit -m "feat(signals): expandable body + reclassify chips in InterviewCard"
- Commit
Task 4: InterviewsView.vue — expand toggle, body display, reclassify chips (pre-list)
Files:
- Modify:
web/src/views/InterviewsView.vue
Context: This view shows signal banners in the "Applied" pre-list rows. Unlike InterviewCard (one bodyExpanded per card), here each signal row can be independently expanded. Use ref<Record<number, boolean>> keyed by sig.id with spread-copy for guaranteed Vue 3 reactivity (same pattern as sigExpandedIds but for body expansion).
Step 4.1: Add bodyExpandedMap, toggleBodyExpand, and reclassifyPreSignal
In the script section, after the dismissPreSignal function (line ~59–63), add:
const bodyExpandedMap = ref<Record<number, boolean>>({})
function toggleBodyExpand(sigId: number) {
bodyExpandedMap.value = { ...bodyExpandedMap.value, [sigId]: !bodyExpandedMap.value[sigId] }
}
const PRE_RECLASSIFY_CHIPS = [
{ label: '🟡 Interview', value: 'interview_scheduled' as const },
{ label: '✅ Positive', value: 'positive_response' as const },
{ label: '🟢 Offer', value: 'offer_received' as const },
{ label: '📋 Survey', value: 'survey_received' as const },
{ label: '✖ Rejected', value: 'rejected' as const },
{ label: '— Neutral', value: 'neutral' },
] as const
async function reclassifyPreSignal(job: PipelineJob, sig: StageSignal, newLabel: string) {
if (newLabel === 'neutral') {
// Optimistic removal
const idx = job.stage_signals.findIndex(s => s.id === sig.id)
if (idx !== -1) job.stage_signals.splice(idx, 1)
await useApiFetch(`/api/stage-signals/${sig.id}/reclassify`, {
method: 'POST',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify({ stage_signal: 'neutral' }),
})
await useApiFetch(`/api/stage-signals/${sig.id}/dismiss`, { method: 'POST' })
} else {
sig.stage_signal = newLabel as StageSignal['stage_signal']
await useApiFetch(`/api/stage-signals/${sig.id}/reclassify`, {
method: 'POST',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify({ stage_signal: newLabel }),
})
}
}
- Add
bodyExpandedMap,toggleBodyExpand,PRE_RECLASSIFY_CHIPS, andreclassifyPreSignalto the script section
Step 4.2: Update the pre-list signal banner template
Find the <!-- Signal banners for pre-list rows --> block (lines ~319–342). Replace it with:
<!-- Signal banners for pre-list rows -->
<template v-if="job.stage_signals?.length">
<div
v-for="sig in (job.stage_signals ?? []).slice(0, sigExpandedIds.has(job.id) ? undefined : 1)"
:key="sig.id"
class="pre-signal-banner"
:data-color="SIGNAL_META_PRE[sig.stage_signal]?.color"
>
<div class="signal-header">
<span class="signal-label">📧 <strong>{{ SIGNAL_META_PRE[sig.stage_signal]?.label?.replace('Move to ', '') ?? sig.stage_signal }}</strong></span>
<span class="signal-subject">{{ sig.subject.slice(0, 60) }}{{ sig.subject.length > 60 ? '…' : '' }}</span>
<div class="signal-header-actions">
<button class="btn-signal-read" @click="toggleBodyExpand(sig.id)">
{{ bodyExpandedMap[sig.id] ? '▾ Hide' : '▸ Read' }}
</button>
<button
class="btn-signal-move"
@click="openMove(job.id, SIGNAL_META_PRE[sig.stage_signal]?.stage)"
>→ Move</button>
<button class="btn-signal-dismiss" @click="dismissPreSignal(job, sig)">✕</button>
</div>
</div>
<!-- Expanded body + reclassify chips -->
<div v-if="bodyExpandedMap[sig.id]" class="signal-body-expanded">
<div v-if="sig.from_addr" class="signal-from">From: {{ sig.from_addr }}</div>
<div v-if="sig.body" class="signal-body-text">{{ sig.body }}</div>
<div v-else class="signal-body-empty">No email body available.</div>
<div class="signal-reclassify">
<span class="signal-reclassify-label">Re-classify:</span>
<button
v-for="chip in PRE_RECLASSIFY_CHIPS"
:key="chip.value"
class="btn-chip"
:class="{ 'btn-chip-active': sig.stage_signal === chip.value }"
@click="reclassifyPreSignal(job, sig, chip.value)"
>{{ chip.label }}</button>
</div>
</div>
</div>
<button
v-if="(job.stage_signals?.length ?? 0) > 1"
class="btn-sig-expand"
@click="togglePreSigExpand(job.id)"
>{{ sigExpandedIds.has(job.id) ? '− less' : `+${(job.stage_signals?.length ?? 1) - 1} more` }}</button>
</template>
- Replace the pre-list signal banner template block
Step 4.3: Add CSS for new elements
The InterviewsView.vue <style> section already has .btn-signal-dismiss, .btn-signal-move, and .signal-actions. Add new rules that do NOT conflict with existing ones — use .signal-header-actions (not .signal-actions) for the right-aligned button group:
.btn-signal-read {
background: none; border: none; color: var(--color-text-muted); font-size: 0.82em;
cursor: pointer; padding: 2px 6px; white-space: nowrap;
}
.signal-header {
display: flex; align-items: center; gap: 8px; flex-wrap: wrap;
}
.signal-header-actions {
margin-left: auto; display: flex; gap: 6px; align-items: center;
}
.signal-body-expanded {
margin-top: 8px; font-size: 0.8em; border-top: 1px dashed var(--color-border);
padding-top: 8px;
}
.signal-from {
color: var(--color-text-muted); margin-bottom: 4px;
}
.signal-body-text {
white-space: pre-wrap; color: var(--color-text); line-height: 1.5;
max-height: 200px; overflow-y: auto;
}
.signal-body-empty {
color: var(--color-text-muted); font-style: italic;
}
.signal-reclassify {
display: flex; gap: 6px; flex-wrap: wrap; align-items: center; margin-top: 8px;
}
.signal-reclassify-label {
font-size: 0.75em; color: var(--color-text-muted);
}
.btn-chip {
background: var(--color-surface); color: var(--color-text-muted);
border: 1px solid var(--color-border); border-radius: 4px;
padding: 2px 7px; font-size: 0.75em; cursor: pointer;
}
.btn-chip:hover {
background: var(--color-hover);
}
.btn-chip-active {
background: var(--color-primary-muted, #e8f0ff);
color: var(--color-primary); border-color: var(--color-primary);
font-weight: 600;
}

Implementation Notes
[→ Move] button label
The spec says keep [→ Move] (no rename). The template above uses → Move for both InterviewCard and InterviewsView pre-list rows. The old text was → {{ SIGNAL_META[sig.stage_signal].label }} which was verbose and confusing. The spec says "pre-selection hint is still useful; MoveToSheet confirm is the safeguard" — so → Move is correct: it still opens MoveToSheet with the pre-selected stage.
signal-header and signal-header-actions layout note
The existing .signal-banner in both files has display: flex; align-items: center. The .signal-header inner div creates a horizontal flex row for label + subject + action buttons. The action button group uses .signal-header-actions (NOT .signal-actions) to avoid conflicting with the existing .signal-actions rule already present in both Vue files. The existing .signal-actions rule does not include margin-left: auto, which is what pushes the buttons to the right — .signal-header-actions adds that. Do not merge or rename .signal-actions; leave it in place for any existing usages.
Neutral chip type safety
RECLASSIFY_CHIPS includes 'neutral' which is not in StageSignal['stage_signal'] union. The reclassifySignal function handles neutral as a special case before attempting the as StageSignal['stage_signal'] cast, so TypeScript is satisfied. The chip.value in the template is typed as the union of all chip values; the btn-chip-active binding uses sig.stage_signal === chip.value which TypeScript allows since it's a === comparison.
Reactive re-labeling (spec §"Reactive re-labeling")
sig.stage_signal = newLabel as StageSignal['stage_signal'] mutates the Pinia reactive proxy directly. This works because sig is accessed through the Pinia store's reactive object chain — Vue 3 wraps nested objects on access. This would silently fail only if job or stage_signals were marked toRaw() or markRaw(), which they are not. The SIGNAL_META[sig.stage_signal] lookups in the template will reactively re-evaluate when sig.stage_signal changes.
bodyExpandedMap in InterviewsView
Uses ref<Record<number, boolean>>({}) (not Map) because Vue 3 can track property mutations on plain objects held in a ref deeply. The spread-copy pattern { ...bodyExpandedMap.value, [sigId]: !bodyExpandedMap.value[sigId] } is the guaranteed-safe approach (same principle as the sigExpandedIds Set copy-on-write pattern already in the file).
