Proof Gallery (C) 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: the screenshots QC agents capture become visible in the dashboard, grouped by feature (B's lane_features slug) and phase. Ported from Shipyard's real implementation (~/MyDrive/Projects/ResearchAndDevelopment/AgentWorkflow/dashboard/server/{routes,services}/proof.js, src/components/ProofGallery.jsx, src/hooks/useProof.js), adapted from Shipyard's flat state/laneN/*.json file model to CCAM's lane_features DB rows (Task B, already shipped).
Architecture: One new library module server/lib/proof.js (list/file/delete/link, all containment-checked against the lane's own proof root — never LANES_ROOT, since an adopted lane's cwd need not live under it). Routes added inline to server/routes/lanes.js, grouped with the other /:id/* sub-resources, same placement rule B's /:id/features used. CLI gains one primitive, ccam lanes proof-link, which is never auto-invoked — matching "CCAM does not orchestrate," a session or hook calls it explicitly. The Workspace UI adds a ProofGallery panel keyed off the same viewedFeatureSlug state Task B's picker already introduced — no second picker.
Tech Stack: Node fs/path (realpath-based containment, no new dependency), existing Express/route conventions, existing React state from Task B.
Global Constraints
- Every applicable source file MUST start with the project's authorship header — verify with
bash .claude/skills/file-headers/scripts/check-headers.sh. - Path containment is the entire security surface. Every one of
proofFile/deleteProof/listProofresolves +fs.realpathSyncs + asserts the result is inside the lane's proof root (base === p || p.startsWith(base + path.sep)) before any read/write/delete reachesfs. No request path — slug, group, file, image name — ever reachesfsunresolved. Port Shipyard'sproofFile/deleteProof/badNamecheck nearly verbatim; do not "clean up" or abstract this logic, it is the one part of C worth reviewing line-by-line. deleteProofnever touchesticket/. Whole-feature delete iterates every subdirectory exceptticket; group delete refusesgroup === "ticket"outright.- The proof root is
<lane.cwd>/.playwright-mcp/proof, not anything underLANES_ROOT. An adopted lane'scwdcan be anywhere the user can read; proof storage follows the lane, same as Shipyard's.playwright-mcp/proofliving inside the worktree. - Grouping comes from
lane_features(Task B), not from re-deriving "current" via a branch regex. Shipyard'suseProof.jsparsesfeat/<slug>out of the git branch because it has no DB; CCAM already hasgetFeature/active_feature_idas the source of truth, so that derivation is deliberately dropped, not ported. ccam lanes proof-linkis a primitive, not automatic. It runsensureProofLinkonce, on request. Nothing in this plan calls it fromfeature activate,lanes up, or any hook — a session or a project's own hook script decides when to call it, same reasoning as every other "CCAM does not orchestrate" primitive.DELETE /api/lanes/:id/proof/:slugtakes{group?, images?}in the JSON body (express.json()is already mounted globally inserver/index.js), matching Shipyard'sdeleteProof(n, req.body || {})— not query params.- Run
npm run test:server(full suite) andnpm run test:client(when a task touchesclient/) plusbash .claude/skills/file-headers/scripts/check-headers.shbefore every commit. - Never use
git add -A. Stage exactly the files each task names.
Task 1: server/lib/proof.js core
Files:
- Create:
server/lib/proof.js - Test:
server/__tests__/proof.test.js
Interfaces:
- Produces:
proofRoot(lane)→string(<lane.cwd>/.playwright-mcp/proof, NOT realpath'd — the directory may not exist yet);ensureProofLink(lane)→{linked: boolean}(idempotent;falsewhen there was nothing to link, e.g. clone-rootproof/already the correct symlink or absent);listProof(laneId)→Array<{slug, groups: {[group]: string[]}, ticket_report: string, mtime: number}>(mtime = latest file mtime under that slug's dir, seconds; sorted most-recently-touched first);proofFile(laneId, slug, group, file)→string | null(absolute realpath, or null if missing/outside root/wrong extension);deleteProof(laneId, {slug, group, images} = {})→{deleted: number}, throwsObject.assign(new Error(...), {code: "EBADPATH"})for a bad slug/group/image name,{code: "ENOFEATURE"}when the slug's directory doesn't exist. listProofmerges in every slug fromlane-features.js'slistFeatures(laneId)that has no proof directory yet (so a just-activated feature with zero screenshots still appears, with emptygroups) — the CCAM-native replacement for Shipyard's_pending/_activespecial-casing, since B'slane_featuresrow already exists the momentactivateis called.

Task 2: GET/DELETE /api/lanes/:id/proof… + POST /:id/proof-link routes
Files:
- Modify:
server/routes/lanes.js - Test:
server/__tests__/proof-api.test.js
Interfaces:
- Consumes:
server/lib/proof.js'slistProof,proofFile,deleteProof,ensureProofLink(Task 1, already committed).
Routes (register near the other /:id/* sub-resources — after /:id/features/..., before /:id/git, same file):
GET /api/lanes/:id/proof -> { features: [ProofFeature, ...] }
GET /api/lanes/:id/proof/:slug/:group/:file -> image or REPORT.html (Content-Type by extension), 404 if not found/contained
DELETE /api/lanes/:id/proof/:slug body: { group?: string, images?: string[] }
-> { deleted: N }
-> 404 { error: { code: "ENOFEATURE", message } }
-> 400 { error: { code: "EBADPATH", message } }
POST /api/lanes/:id/proof-link -> { linked: boolean }
ProofFeature = {slug, groups: {[group]: string[]}, ticket_report: string, mtime: number}, exactly listProof's shape — no extra computed fields needed (unlike B's featurePayload, there's no pipeline to compute here).

Step 2: Run test to verify it fails
Run: node --test server/__tests__/proof-api.test.js
Expected: FAIL — 404s across the board (routes not registered).
Step 3: Add the routes
In server/routes/lanes.js, add near the top imports:
const proofLib = require("../lib/proof");
Add the routes right after the /:id/features/activate route (search for that, added in Task B) and before /:id/git:
router.get("/:id/proof", (req, res) => {
const lane = lanesLib.getLane(req.params.id);
if (!lane) return res.status(404).json({ error: { code: "ENOLANE", message: "lane not found" } });
res.json({ features: proofLib.listProof(lane.id) });
});
router.get("/:id/proof/:slug/:group/:file", (req, res) => {
const lane = lanesLib.getLane(req.params.id);
if (!lane) return res.status(404).send("not found");
const p = proofLib.proofFile(lane.id, req.params.slug, req.params.group, req.params.file);
if (!p) return res.status(404).send("not found");
const ext = path.extname(p).toLowerCase();
const contentType =
ext === ".html" ? "text/html; charset=utf-8" : ext === ".png" ? "image/png" : "image/jpeg";
res.type(contentType).sendFile(p);
});
router.delete("/:id/proof/:slug", sameOriginGuard, (req, res) => {
const lane = lanesLib.getLane(req.params.id);
if (!lane) return res.status(404).json({ error: { code: "ENOLANE", message: "lane not found" } });
try {
const result = proofLib.deleteProof(lane.id, {
slug: req.params.slug,
group: req.body?.group,
images: req.body?.images,
});
res.json(result);
} catch (err) {
if (err.code === "ENOFEATURE") {
return res.status(404).json({ error: { code: err.code, message: err.message } });
}
if (err.code === "EBADPATH") {
return res.status(400).json({ error: { code: err.code, message: err.message } });
}
res.status(500).json({ error: { code: err.code, message: err.message } });
}
});
router.post("/:id/proof-link", sameOriginGuard, (req, res) => {
const lane = lanesLib.getLane(req.params.id);
if (!lane) return res.status(404).json({ error: { code: "ENOLANE", message: "lane not found" } });
res.json(proofLib.ensureProofLink(lane));
});
path (node:path) is already imported at the top of server/routes/lanes.js for the /worktree route — confirm with grep -n "require(\"node:path\")\|require('path')" server/routes/lanes.js before adding a second import.
Step 4: Run test to verify it passes
Run: node --test server/__tests__/proof-api.test.js
Expected: PASS (7 tests)
Step 5: Run the full suite and header audit
Run: npm run test:server && bash .claude/skills/file-headers/scripts/check-headers.sh
Step 6: Commit
git add server/routes/lanes.js server/__tests__/proof-api.test.js
git commit -m "feat(lanes): expose GET/DELETE /api/lanes/:id/proof + proof-link over proof.js (C)"
Task 3: ccam lanes proof-link CLI
Files:
- Modify:
bin/ccam.js
Interfaces:
- Consumes:
POST /api/lanes/:id/proof-link(Task 2, already committed) via the existingposthelper. - Consumes:
resolveLaneArg(already defined inbin/ccam.js).
Step 1: Add the command implementation
In bin/ccam.js, near cmdFeatureShow (search for that function, added in Task B), add:
/** `ccam lanes proof-link [<id>] [--cwd path]` — converge the clone-root
* `proof/` onto `.playwright-mcp/proof` (idempotent). Never run automatically
* by anything else in this codebase; a session or hook calls it explicitly. */
async function cmdLanesProofLink(args) {
const resolved = await resolveLaneArg(args);
if (!resolved) return;
const { linked } = await post(`/api/lanes/${resolved.laneId}/proof-link`);
console.log(
linked
? `${c.green("✔")} linked proof/ -> .playwright-mcp/proof`
: "proof/ already linked, nothing to do"
);
}
Step 2: Wire the subcommand dispatch
In bin/ccam.js's case "lanes": block (search for other lanes subcommands like up/down/hook), add:
if (sub === "proof-link") return cmdLanesProofLink(rest.slice(1));
Step 3: Add the help-table entry
In bin/ccam.js's COMMAND_GROUPS, in the "Lanes" group, add after the lanes hook row:
["lanes proof-link", "[<id>]", "Converge clone-root proof/ onto .playwright-mcp/proof (idempotent, never automatic)"],
Step 4: Manual smoke test
ccam lanes add --cwd $(pwd) --title "smoke"
ccam lanes proof-link
ls -la proof # should be a symlink -> .playwright-mcp/proof
ccam lanes proof-link # second run: "already linked, nothing to do"
Step 5: Commit
git add bin/ccam.js
git commit -m "feat(lanes): add ccam lanes proof-link CLI (C)"
Task 4: Workspace UI — proof gallery panel
Files:
- Modify:
client/src/lib/api.ts - Modify:
client/src/lib/types.ts - Modify:
client/src/pages/Workspace.tsx - Modify:
client/src/i18n/locales/en/lanes.json,client/src/i18n/locales/vi/lanes.json - Test:
client/src/pages/__tests__/Workspace.test.tsx
Interfaces:
- Consumes:
GET /api/lanes/:id/proof,DELETE /api/lanes/:id/proof/:slug(Task 2, already committed). Imagesrcattributes point directly atGET /api/lanes/:id/proof/:slug/:group/:file(no client fetch needed for the images themselves — the<img>tag hits it). - Keys off the same
viewedFeatureSlugstate Task B'sWorkspace.tsxalready introduced — no second picker, no separate "current feature" derivation.
Read client/src/lib/api.ts, client/src/lib/types.ts, and Task B's feature-picker code in client/src/pages/Workspace.tsx FIRST (search for viewedFeatureSlug) before writing anything below — this task is additive to that state, not a parallel selector. Also skim Shipyard's ProofGallery.jsx (~/MyDrive/Projects/ResearchAndDevelopment/AgentWorkflow/dashboard/src/components/ProofGallery.jsx) for the rendering shape (grouped thumbnails, +N overflow at CAP = 8, cleanup-mode multi-select) — port its JSX structure, not its _active/useProof.js state bookkeeping, which Task B's picker already replaces.
Step 1: Add types and API client methods
In client/src/lib/types.ts, add near LaneFeature (Task B):
export interface ProofFeature {
slug: string;
groups: Record<string, string[]>;
ticket_report: string;
mtime: number;
}
In client/src/lib/api.ts, add to the lanes API object, alongside features:
proof: {
list: (laneId: number): Promise<{ features: ProofFeature[] }> =>
/* the real fetch helper */(`/api/lanes/${laneId}/proof`),
imageUrl: (laneId: number, slug: string, group: string, file: string): string =>
`/api/lanes/${laneId}/proof/${encodeURIComponent(slug)}/${encodeURIComponent(group)}/${encodeURIComponent(file)}`,
delete: (
laneId: number,
slug: string,
body: { group?: string; images?: string[] }
): Promise<{ deleted: number }> =>
/* the real fetch helper, DELETE method, JSON body */(`/api/lanes/${laneId}/proof/${encodeURIComponent(slug)}`, body),
},
Match the exact fetch-helper name/signature this file already uses for a DELETE-with-body call (check how an existing DELETE-with-body client method is written, e.g. search for method: "DELETE" in this file) rather than guessing at the helper's calling convention.
Step 2: Add the gallery panel to Workspace.tsx
Inside the Workspace component, alongside Task B's viewedFeatureSlug/features/viewedFeature state, add:
const [proofFeatures, setProofFeatures] = useState<ProofFeature[]>([]);
useEffect(() => {
if (!currentLane) {
setProofFeatures([]);
return;
}
api.lanes.proof
.list(currentLane.id)
.then((data) => setProofFeatures(data.features))
.catch(() => setProofFeatures([]));
}, [currentLane?.id, viewedFeatureSlug]);
const activeSlug = viewedFeatureSlug ?? currentLane?.active_feature_slug ?? null;
const proofFeature = activeSlug ? proofFeatures.find((f) => f.slug === activeSlug) : null;
(currentLane.active_feature_slug — verify the exact field name the live lane payload uses for "which feature slug is currently active"; Task B's featurePayload/payload may expose it under a different key such as active_feature_id requiring a lookup into features by id instead. Read payload() in server/routes/lanes.js to confirm before writing this line.)
Render the gallery below PipelineMap (near Task B's feature-viewer-banner):
{proofFeature && (Object.keys(proofFeature.groups).length > 0 || proofFeature.ticket_report) && (
<div data-testid="proof-gallery" className="mt-2">
{proofFeature.ticket_report && (
<a
href={`/api/lanes/${currentLane.id}/proof/${proofFeature.ticket_report}`}
target="_blank"
rel="noreferrer"
className="text-xs text-fg-muted"
>
{tLanes("proof.ticketReport")}
</a>
)}
{Object.entries(proofFeature.groups).map(([group, images]) => (
<div key={group} className="mt-1">
<span className="text-xs text-fg-muted">{group} · {images.length}</span>
<div className="flex flex-wrap gap-1">
{images.slice(0, 8).map((img) => (
<img
key={img}
loading="lazy"
className="h-16 w-16 rounded object-cover"
src={api.lanes.proof.imageUrl(currentLane.id, proofFeature.slug, group, img)}
alt={img}
/>
))}
{images.length > 8 && (
<span className="text-xs text-fg-muted">+{images.length - 8}</span>
)}
</div>
</div>
))}
</div>
)}
Match this file's real conditional-rendering, className tokens, and tLanes() conventions — read the surrounding JSX first rather than transcribing this verbatim. Delete/cleanup-mode UI (multi-select + api.lanes.proof.delete) is a ponytail-eligible follow-up, not required for this task's verify step below — a viewer with no delete affordance is still a complete, useful C; add delete once the read path is confirmed working, same increment-by-increment approach the rest of this plan takes.
Step 3: Add i18n strings
Add to both client/src/i18n/locales/en/lanes.json and vi/lanes.json, under the "features" group added in Task B (or a sibling "proof" group, matching whichever this file's existing convention prefers for a related-but-distinct concern):
"proof": {
"ticketReport": "Task report"
}
(Vietnamese translation matching this repo's existing tone in vi/lanes.json.)
Step 4: Write a test
In client/src/pages/__tests__/Workspace.test.tsx, find how Task B's test mocks api.lanes.features.list/.show and follow the same pattern for api.lanes.proof.list:
it("shows the proof gallery for the selected feature", async () => {
vi.mocked(api.lanes.proof.list).mockResolvedValue({
features: [
{ slug: "one", groups: { "qc-local": ["a.png", "b.png"] }, ticket_report: "", mtime: 0 },
],
});
// ... render, select the lane (and "one" via Task B's picker if it isn't already active) ...
// assert screen.getByTestId("proof-gallery") appears with 2 images
});
it("shows no gallery panel when the selected feature has no proof", async () => {
vi.mocked(api.lanes.proof.list).mockResolvedValue({ features: [] });
// ... render, select the lane ...
// assert screen.queryByTestId("proof-gallery") is null
});
Read this file's existing render/selection helpers first and mirror them rather than guessing at the render setup.
Step 5: Run the client test suite
Run: npm run test:client
Expected: green, including the two new tests.
Step 6: Commit
git add client/src/lib/api.ts client/src/lib/types.ts client/src/pages/Workspace.tsx client/src/i18n/locales/en/lanes.json client/src/i18n/locales/vi/lanes.json client/src/pages/__tests__/Workspace.test.tsx
git commit -m "feat(lanes): show proof gallery panel in the Workspace page (C)"
Task 5: Documentation
Files:
- Modify:
docs/LANES.md - Modify:
docs/CLI.md - Modify:
docs/API.md - Modify:
ARCHITECTURE.md - Modify:
docs/superpowers/plans/2026-08-03-shipyard-parity-lanes.md(mark C done)
Interfaces: none — documentation only.
Step 1: docs/LANES.md
Add a new top-level section (after "Per-feature state and archive", before "Cross-lane named locks" — search for both headings) titled ## Proof gallery, covering:
- Why: QC screenshots land on disk during a lane's work; this makes them visible in the dashboard, grouped by feature (Task B's slug) and phase.
- Storage layout:
<lane.cwd>/.playwright-mcp/proof/<slug>/{<phase-group>,ticket}/. ensure_proof_link's purpose and that it is never automatic —ccam lanes proof-linkis an explicit primitive, same "CCAM does not orchestrate" reasoning as every other primitive in this project.- The security invariant stated exactly: every proof route resolves + realpaths + checks containment before touching
fs;deleteProofnever removesticket/. - The Workspace panel reuses Task B's feature picker — no second selector.
Step 2: docs/CLI.md
Add to the ### Lanes table, after the lanes hook row:
| `ccam lanes proof-link [<id>]` | Converge clone-root `proof/` onto `.playwright-mcp/proof` (idempotent, never run automatically) |
Step 3: docs/API.md
Add a ### Lane proof gallery section documenting GET /api/lanes/:id/proof, GET /api/lanes/:id/proof/:slug/:group/:file, DELETE /api/lanes/:id/proof/:slug, POST /api/lanes/:id/proof-link — request/response bodies and status codes exactly as specified in Task 2. Place it as its own subsection under ### Lanes, near the "Lane features" section Task B added (confirm the insertion point with grep -n "^### \|^#### " docs/API.md first).
Step 4: ARCHITECTURE.md
Add a new row to the module responsibility table, near the lib/lane-features.js row:
| `lib/proof.js` | (C) Proof gallery: lists/serves/deletes QC screenshots grouped by feature slug (Task B's `lane_features`) and phase, under `<lane.cwd>/.playwright-mcp/proof/<slug>/<group>/`. Every path is resolved, realpath'd, and containment-checked before touching `fs` — the entire security surface. `ensureProofLink` ports Shipyard's `ensure_proof_link` (converge a stray clone-root `proof/` onto the canonical dir); never auto-invoked, exposed only as `ccam lanes proof-link` |
Step 5: Mark C done in the parent plan
In docs/superpowers/plans/2026-08-03-shipyard-parity-lanes.md, update the status table row for **C** to ✅ **done** <today's date>, and confirm **E**'s dependency line (A2·B·C·D) still reads correctly now that C is done too — do not mark E done, it is unstarted.
Step 6: Verify and commit
