# PHASE 0 — PinScope / Periscope forensic audit

**Status:** observational only. No source, license, git history, remotes, or fork relationship was modified as part of this audit.  
**Goal:** architectural independence of Periscope from PinScope — not deletion of every inherited line.  
**Does not implement Phase 1.** Disposition labels are inventory, not a rewrite plan.

## 1. Executive summary

Periscope is a **live GitHub fork** of Faradworks/Pinscope (AGPL-3.0). Upstream has **five** commits and has not moved since 2026-07-17. GitHub `main` on the fork is only **three** commits ahead (Docker / OSS / README). The **product** (DeepSeek, rebrand, PCB exam, finding engine, v2.32.1) lives on `cursor/pcb-review-plan-44dd`: **92** commits ahead of upstream, **89** ahead of `origin/main`, **not merged** to the default branch. GitHub lists **no pull requests**.

On the product snapshot (`facbaa2`, 404 files, 123 544 text lines):

| Class | Files | File % | Lines | Line % |
| --- | --- | --- | --- | --- |
| UPSTREAM (identical blob) | 125 | 30.9% | 45 211 | 36.6% |
| DERIVED (measurable overlap with an upstream path or rename) | 127 | 31.4% | 52 455 | 42.5% |
| REPLACEMENT (same path, Jaccard < 0.20) | 4 | 1.0% | 359 | 0.3% |
| NEW (no upstream match at the thresholds below) | 139 | 34.4% | 24 437 | 19.8% |
| THIRD_PARTY (`vendor/` except empty `__init__.py` mis-tagged — see §3) | 9 | 2.2% | 1 082 | 0.9% |
| UNKNOWN | 0 | — | — | — |

**PinScope-lineage share (UPSTREAM + DERIVED + REPLACEMENT):** 63.4% of files, 79.4% of lines.  
**New / vendored share (NEW + THIRD_PARTY):** 36.6% of files, 20.7% of lines.

Architectural independence is **not** blocked by leftover strings. It **is** blocked by: (1) the still-PinScope pipeline (`periscopex` ← `pinscopex`: graph, parsers, `validate.py`, extraction, Next.js report shell); (2) Faradworks legal/metadata identity still shipping in the UI; (3) GitHub `main` not carrying the product; (4) Clerk / Anthropic seams still in the runtime graph; (5) vendored ImpedenceFinder with **no license file and GitHub `license: null`**.

Most important to replace **first** (identity and branch topology), not the finding engine or PCB job: Faradworks terms/privacy/contact/metadata; then isolate Clerk and Anthropic; keep parsers/graph as KEEP until a later phase.

## 2. Method and non-goals

**Compared trees**

- Upstream: `git fetch` of `https://github.com/Faradworks/Pinscope.git` into a **local** remote named `upstream` on a disposable clone. This audit did not `git remote set-url`, force-push, rewrite history, or detach the GitHub fork.
- Product: `origin/cursor/pcb-review-plan-44dd` (also compared `origin/main` and `origin/cursor/deepseek-71c5`).
- File identity: `git ls-tree` blob SHAs.
- Text overlap: line-**set** Jaccard on `git show` text. Thresholds (fixed, not guessed): identical SHA → UPSTREAM; same path and Jaccard ≥ 0.20 **or** ≥ 20 shared lines → DERIVED; same path and below that → REPLACEMENT; path only in HEAD with identical SHA to an unmatched upstream blob, or Jaccard ≥ 0.15 against a basename / `pinscopex`→`periscopex` map → DERIVED/REPLACEMENT with `renamed_from`; `vendor/` → THIRD_PARTY; else NEW.
- Licenses: root `LICENSE` blob vs upstream; npm `license` field on **every** `frontend/package-lock.json` `packages` entry (827 entries, 0 missing); PyPI JSON `info.license` / `license_expression` / License classifiers for each `backend/requirements.txt` name; ImpedenceFinder GitHub API + tree + `pyproject.toml` + `LICENSE` URL. **No license was inferred from a package name.**
- Strings: ripgrep for `Pinscope`, `PinScope`, `pinscope`, `Faradworks`, `faradworks`, `SPDX`, `copyright` (lockfile excluded from hit lists). Matches were classified, not deleted.

**Classifier caveat (empty blobs):** git empty-file SHA `e69de29` is shared by `backend/__init__.py` (UPSTREAM) and three HEAD empty files. The rename heuristic tagged `backend/periscopex/__init__.py`, `tests/impedancefinder/__init__.py`, and `vendor/impedancefinder/__init__.py` as DERIVED-from-`backend/__init__.py`. That is **not** a meaningful derivation. Corrected intent: package markers NEW / THIRD_PARTY. Counts in §1 are the **raw** classifier (reproducible). Adjusted: DERIVED 124, NEW 141, THIRD_PARTY 10.

**Non-goals:** no refactors, no PCB/finding-engine edits, no license changes, no history rewrite, no “delete every PinScope line.”

## 3. Git history map

### 3.1 Exact upstream and remotes (GitHub, not this clone)

From `GET https://api.github.com/repos/manvalan/periscope` (2026-09-20):

| Field | Value |
| --- | --- |
| `full_name` | `manvalan/periscope` |
| `fork` | `true` |
| `parent.full_name` / `source.full_name` | `Faradworks/Pinscope` |
| `default_branch` | `main` |
| `license.spdx_id` | `AGPL-3.0` (same as parent) |
| `created_at` | 2026-07-17T16:23:01Z |
| Parent `pushed_at` | 2026-07-17T07:34:32Z |
| Fork `pushed_at` | 2026-09-20T07:13:57Z |
| Open / listed PRs | `[]` (empty) |

GitHub still records a **fork of Faradworks/Pinscope**. This audit did not detach it.

Visible `origin` branches: `main`, `cursor/deepseek-71c5`, `cursor/pcb-review-plan-44dd`. Upstream GitHub has only `main`.

### 3.2 Upstream commit list (complete — 5 commits)

| SHA | Date | Author | Subject |
| --- | --- | --- | --- |
| `6672d2be5744239bd6edfee8abc2ac43d3705f93` | 2026-07-17 | Siddharth Kothari `<Sid@faradworks.com>` | Pinscope open-source core (root commit; extracted from cloud codebase; auth/billing in private gateway) |
| `6e83ef9da021ae3a21b76bf38058f034e8dc40d9` | 2026-07-17 | Siddharth Kothari | Remove internal review case log; public support address |
| `f89ca0803f571a57703766a154d628def1fe3696` | 2026-07-17 | Siddharth Kothari | README: rewrite for the public launch |
| `a8c242933a6917aaeeade383c09f0ea998d467d0` | 2026-07-17 | Siddharth Kothari | README: add pipeline diagram |
| `b26ad3509f4a19878fb7050aad3da9eacba8d914` | 2026-07-17 | Sid / GitHub | Update README.md (demo screenshot) |

`upstream/main` **is** `b26ad35`. Fork `origin/main` contains those five plus three fork-only commits. **0** upstream commits are missing from the fork (ahead/behind `upstream/main...origin/main` = `0 3`).

### 3.3 Divergence

```
6672d2b  Pinscope OSS root (Faradworks)
   …
b26ad35  upstream/main = merge-base
   ├─ origin/main (+3)
   │     4888092 Docker, remove Clerk, OSS mode
   │     2c5d9d3 Document fork changes in README
   │     ab1c5b0 Fix Anthropic skill references and backend git support
   └─ origin/cursor/pcb-review-plan-44dd (+92 from upstream, +89 from origin/main)
         48246f3 Adapt Pinscope to DeepSeek, auto datasheets, shared library
         … DeepSeek, KiCad, layout F1, placement, impedance, rebrand 8d2b856,
           PCB job 16c606a, finding engine dc65e96, … facbaa2 (2.32.1)
         origin/cursor/deepseek-71c5 is 14 commits behind pcb-review (linear ancestor)
```

`origin/main` does **not** contain DeepSeek, `periscopex`, PCB exam, or the rebrand. A clone of default `main` is still branded Pinscope plus Docker.

### 3.4 Periscope vs PinScope authorship on product snapshot

`git log --format='%an <%ae>'` on `origin/cursor/pcb-review-plan-44dd` (97 commits including upstream):

| Count | Author |
| --- | --- |
| 88 | Michele Bigi `<mikbigi@gmail.com>` |
| 2 | manvalan `<mikbigi@gmail.com>` |
| 1 | Michele `<mikbigi@gmail.com>` |
| 1 | Cursor Agent `<cursoragent@cursor.com>` |
| 3 | Siddharth Kothari `<siddkot@gmail.com>` |
| 1 | Siddharth Kothari `<Sid@faradworks.com>` |
| 1 | Sid `<44057927+Monacrylic@users.noreply.github.com>` |

PinScope authors = the five upstream commits. Periscope authors = the 92 fork commits (Michele / manvalan / Cursor Agent).

### 3.5 Product commit spine (fork-only, oldest → newest groups)

Not every SHA is repeated here; `git log origin/main..origin/cursor/pcb-review-plan-44dd` is the complete 89-commit list. Grouped:

1. **DeepSeek / library** (`48246f3` … `30aaf55`): OpenAI-compatible provider, local skills, datasheet fetch, catalog passives, reprocess, quote verify.
2. **CAD / KiCad** (`e4fd6c3` … `c5b260b`): hierarchy zip, `.kicad_sch` / `.kicad_pcb` nets, cad-bridge plugin later.
3. **Deterministic schematic checks** (`b1ee445` … `7aed64c`): decoupling, I2C, DNP, sequencing, thermal, errata, layout_rules.
4. **Impedance / antenna** (`6fc2ac5` … `556306b`): vendored ImpedenceFinder, RF tab.
5. **Auth** (`5a69b38`): local multi-user JWT (PinScope-named originally).
6. **Layout F1 / Placement F2** (`2950446` … `86121e6`): domains, satellites, gated xy pack.
7. **Rebrand** (`8d2b856`, `dc364f5`): Pinscope → Periscope, `pinscopex` → `periscopex`, `PS-*` → `PE-*`.
8. **Deploy** (`6b0e44a` … `344ecb3`): `/root/periscope`, Docker networks `pinscope_pinscope` / `pinscope_periscope`.
9. **PCB exam + finding engine** (`721ede4` … `facbaa2`): MODE=pcb, shared `library/extracted`, FACT/REQUIREMENT/INFERENCE.

## 4. File classification vs upstream

Rules: see §2. Full per-file table: **Appendix A**. Snapshot: 404 HEAD files vs 254 upstream files.

**Unmatched upstream path still absent from HEAD:** `backend/pinscopex/__init__.py` (package renamed; other `pinscopex/*` files matched as `periscopex/*`).

**REPLACEMENT (4)** — same path, low overlap:

| Path | Jaccard | Note |
| --- | --- | --- |
| `README.md` | 0.133 | DeepSeek/Periscope README vs Pinscope launch README |
| `frontend/src/lib/auth.ts` | 0.093 | Local JWT + legacy `pinscope_token` vs open-core stub |
| `frontend/src/components/layout/sidebar-auth.tsx` | 0.105 | Local account UI vs Clerk seam stub |
| `skills/extract-pintable/SKILL.md` | 0.066 | Prompt rewritten; sibling `schema.json` / `validate.py` still DERIVED |

**THIRD_PARTY:** `vendor/impedancefinder/*` except `__init__.py` (empty-blob caveat). `SOURCE.md` cites https://github.com/manvalan/ImpedenceFinder commit `a0c8d0ec37c9a1b099082926e50a245778ec8d6e`. Wrapper `backend/periscopex/impedance.py` is NEW. Tests under `tests/impedancefinder/` are NEW (except empty `__init__` mis-tag).

**NEW (high-signal, not exhaustive):** `finding_engine.py`, PCB/placement/antenna/impedance modules, `pcb_pipeline.py` / `placement_pipeline.py`, DeepSeek/local skill/PDF ingest, local auth routers, KiCad plugin, `docs/motore-finding.md`, `docs/piano-pcb-review.md`, `scripts/update-periscope.sh`, `docker-compose.yml`.

**DERIVED core:** `backend/periscopex/{graph,models,parsers,parsers_edif,validate,validation_tools,resolve_passives,derating,bom_summary,taxonomy,pin_mux_check,led_current_check}.py` with Jaccard typically 0.63–0.98 vs `backend/pinscopex/*`. `parsers_edif.py`, `pin_function_tokens.py`, `taxonomy.py` are **identical blobs** after rename.

**UPSTREAM clusters:** `LICENSE` (identical AGPL-3.0 text), most `frontend/src` primitives / marketing assets, `frontend/public`, `skills/extract-pattern` + `extract-specs` trees, most `taxonomy/*.json`, `simple_project` netlist/BOM/PDF/design_graph, several `backend/services` and routers unchanged.

---

## 5. Architectural dependency map (PinScope → Periscope)

Strengths: **DIRECT** = still the same module/control flow; **INDIRECT** = new code that imports DIRECT modules; **WEAK** = naming, docs, compatibility aliases, unused seams; **NONE** = no PinScope type/control coupling observed.

```
PinScope OSS (pinscopex + FastAPI + Next.js + skills)
    │ DIRECT
    ├─ Design graph / BOM / netlist parsers / taxonomy / derating
    ├─ LLM review loop (validate.py, validation_tools, extraction, pipeline.py)
    ├─ Finding Pydantic model + normalize/dedupe
    ├─ Next.js report / project / admin shell
    ├─ Clerk/billing gateway seams (stubs + remaining calls)
    └─ Claude Console skills contract (manifest + upload_skills.py)
           │
           ▼
Periscope (rebrand + DeepSeek + extra jobs)
    │ INDIRECT (new jobs on the same graph/library)
    ├─ MODE=pcb (pcb_pipeline → parsers_kicad_pcb, graph, validate._parse_review, finding_engine)
    ├─ MODE=placement
    ├─ cad-bridge / KiCad plugin
    ├─ finding_engine.complete_finding() wrapping models.Finding
    └─ datasheet finder / Mouser / local skills (replaces Anthropic upload in practice)
           │
           WEAK
    ├─ pinscope_version alias, pinscopex: localStorage, pinscope_token, JWT issuer pinscope-local
    ├─ Docker network names pinscope_*
    ├─ Faradworks terms/privacy/metadata/Twitter
    └─ CLAUDE.md still describing Console Skills while README forbids Anthropic
           │
           NONE (new engines, still may import geometry types)
    ├─ antenna_geometry / antenna_rf
    └─ vendor ImpedenceFinder (third party) via vendor_path
```

| Subsystem | Strength | Evidence |
| --- | --- | --- |
| `periscopex.graph` / `parsers*` / `models` / `taxonomy` | DIRECT | Rename + high Jaccard; `pipeline.py` still `build_graph` / `parse_bom` / `parse_netlist_any` |
| `periscopex.validate` / `validation_tools` / `services/validation.py` | DIRECT | Same per-IC datasheet review; `complete_findings` grafted at end of validate |
| `services/pipeline.py` + `pipeline_worker.py` | DIRECT | Same stage machine; provider swapped |
| `finding_engine.py` | INDIRECT | NEW; imports `models.Finding`; seeds `PE-*`; used by `validate.py` and `pcb_checks.py` |
| PCB exam (`pcb_pipeline`, `pcb_*`) | INDIRECT | NEW; `ensure_graph` uses PinScope graph; AI path reuses `_parse_review` |
| Placement F2 | INDIRECT | NEW on `functional_groups` + graph |
| Impedance tab | INDIRECT + THIRD_PARTY | NEW facade; solver from vendor |
| Frontend report / wizard | DIRECT / DERIVED | Same App Router tree; FindingCard extended |
| Local auth | REPLACEMENT + WEAK | Replaces Clerk for self-host; Clerk still in `middleware/auth.py`, admin, email |
| Legal content | DIRECT | `terms.md` / `privacy.md` still Faradworks, Inc. |
| `skills/extract-pattern`, `extract-specs` | DIRECT | UPSTREAM blobs |
| `skills/extract-pintable/SKILL.md` | REPLACEMENT | Contract (schema/validate) still DERIVED |
| `scripts/upload_skills.py` | DIRECT | UPSTREAM; README on product branch says do not run it |
| Docker / `update-periscope.sh` | WEAK / NONE | New deploy; leftover `pinscope` host/network names |
| `LICENSE` | DIRECT | Identical AGPL-3.0 |

PCB/finding-engine **code was not modified** for this audit. Observation only: PCB is already a second job, but it is not architecturally independent of PinScope’s graph, pintable cache, or review parser.

## 6. Package and lockfile licenses

Root project license: **GNU AGPL v3** text, blob-identical to upstream (`LICENSE` = UPSTREAM). README on the product branch: “AGPL-3.0, same as upstream Pinscope (Faradworks). For commercial licensing of the original, write to dev@faradworks.com.” GitHub API also reports `AGPL-3.0` on both repos. No `SPDX-License-Identifier` headers in the tree (0 files).

There is **no** Python lockfile (`poetry.lock` / `uv.lock` / `requirements.lock`). Versions below are **declared ranges** plus **PyPI’s current JSON license field** (fetched 2026-09-20), not the exact installed wheel in a given deploy.

### 6.1 `backend/requirements.txt` (direct)

## 7. String search: Pinscope / PinScope / pinscope / Faradworks / SPDX / copyright

**Do not remove these in Phase 0.** Classification only.

| Needle | Files | Match lines (approx) | Class of hits |
| --- | --- | --- | --- |
| `PinScope` | 0 | 0 | none |
| `SPDX` | 0 | 0 | none in source |
| `copyright` / `Copyright` | 1 (`LICENSE`) | AGPL template + FSF | UPSTREAM license text |
| `Pinscope` | 3 | 4 | README license line; changelog rebrand notes; deploy CORS comment |
| `pinscope` (any case via listing) | 9 | 30 | legacy IDs, paths, Docker networks, clone URL |
| `Faradworks` | 8 | 67 | terms, privacy, marketing, layout metadata, footers |
| `faradworks` | 7 | 21 | `dev@faradworks.com`, faradworks.com, `@getFaradWorks` |

### 7.1 Compatibility / ops (KEEP or ISOLATE — still serving a migration)

| Location | Hit | Role |
| --- | --- | --- |
| `backend/services/projects.py` | `pinscope_version` alias | Reads old `project.json` |
| `frontend/src/lib/api.ts` | `p.pinscope_version` | Same |
| `frontend/src/lib/auth.ts` | `LEGACY_TOKEN_STORAGE_KEY = "pinscope_token"` | Pre-rebrand JWT |
| `frontend/src/lib/storage-keys.ts` | still **writes** `pinscopex:*` keys | Comment says migrate; implementation still PinScope prefix |
| `scripts/update-periscope.sh` / `docker-compose.yml` | `pinscope_pinscope`, `pinscope.michelebigi.it`, clone `manvalan/pinscope` | Live VPS topology |
| `frontend/content/changelog.md` | historical Pinscope / `PS-*` | Documentation of migration |

### 7.2 Faradworks identity still on the Periscope product UI (REPLACE for independence; not “delete PinScope code”)

| Location | Hit |
| --- | --- |
| `frontend/src/app/layout.tsx` | `authors` / `creator` / `publisher`: Faradworks; `url: https://faradworks.com` |
| `frontend/src/lib/site.ts` | `TWITTER_HANDLE = "@getFaradWorks"`; `SITE_NAME` already `"Periscope"` |
| `frontend/src/components/legal/*` | `© {year} Faradworks` |
| `frontend/content/terms.md` | Entire TOS: Faradworks, Inc. Delaware; ownership of “the Service”; `dev@faradworks.com` |
| `frontend/content/privacy.md` | Faradworks contact |
| `frontend/src/app/(marketing)/page.tsx`, `contact/*` | `dev@faradworks.com` |
| `README.md` | commercial license → `dev@faradworks.com` |

`terms.md` still defines the operator as Faradworks while `SITE_URL` defaults to `https://periscope.michelebigi.it`. That is a **product-identity coupling**, not a parser coupling.

### 7.3 © in LICENSE

FSF copyright on the AGPL **license document** itself (2007). That is expected and KEEP. No per-file `Copyright (C) Faradworks` headers were found in `.py`/`.ts` (search limited as in §2). Absence of headers ≠ absence of copyright; the fork inherits AGPL obligations from the parent work.

## 8. Duplicated concepts and partial migrations

| Concept | PinScope side (still present) | Periscope side | Migration state |
| --- | --- | --- | --- |
| Package name | `backend/pinscopex` gone; empty `__init__` only unmatched | `backend/periscopex` | **Done** (rename); imports updated |
| Finding IDs | changelog `PS-*` | `PE-*` in finding_engine | **Done** for new IDs; old reports not in repo |
| App version field | `pinscope_version` alias | `periscope_version` | **Partial** — dual read |
| Browser storage | `pinscopex:` keys still **produced** | comment claims migration | **Partial / inverted** |

## 9. Technical quality observations (no rewrite proposals)

These are facts about the snapshot, not a license to rip out PinScope.

1. **Default branch is not the product.** Anyone cloning `manvalan/periscope` without a branch flag gets pre-DeepSeek Pinscope + Docker (`ab1c5b0`). Live notes refer to 2.32.1 on the PCB branch.
2. **Docs disagree:** `CLAUDE.md` (DERIVED, Jaccard 0.67) still titles Periscope but describes Claude Console Skills as required. Product `README.md` (REPLACEMENT) says skills are local and Anthropic must not be used.
3. **Finding engine is a clamp, not a new IR.** `validate.py` still produces `Finding` objects; `complete_findings` fills FACT/REQUIREMENT/INFERENCE. Replacing PinScope review in one shot would discard the working schematic loop.
4. **PCB job correctly refuses auto-place** (comments in `pcb_pipeline.py`) but **depends** on schematic graph + pintable cache (“run schematic review first”). That is coupling, not a bug by itself.
5. **Empty `__init__.py` files** share one git blob; mechanical rename detection over-claims derivation (§2).
6. **`frontend/package-lock.json` is almost identical to upstream** (Jaccard 0.999) while app version moved to 2.26.3/2.32.1 — lock **name-version** stale; dependency licenses still readable from the lock.
7. **PyMuPDF dual AGPL/commercial** on PyPI is a distribution constraint for binaries/SaaS (AGPL network clause already applies via root LICENSE). Recorded, not changed.
8. **ImpedenceFinder** has no license metadata. KiCad formula comments are provenance of **math**, not a license grant.
9. **xlsx@0.18.5** lock field is Apache-2.0 (not guessed from “SheetJS”).
10. **Auth production guard** still mentions Clerk (`backend/main.py`, `update-periscope.sh` dies if `ENVIRONMENT=production` without Clerk). Local JWT exists but deploy script language is mixed.
11. **No per-source-file copyright/SPDX** — harder provenance later; AGPL still applies to the combined work.
12. Tests for NEW modules are substantial (`tests/test_pcb_review.py`, `test_finding_engine.py`, etc.) — quality of *additions* is high relative to unmerged `main`.

## 10. Disposition (KEEP / ISOLATE / REPLACE / REMOVE / INVESTIGATE)

Independence means Periscope can evolve its product, legal identity, and review contract without pretending to be Faradworks/Pinscope. It does **not** mean deleting `graph.py`.

| Area | Action | Why |
| --- | --- | --- |
| AGPL `LICENSE` blob | **KEEP** | Identical upstream license; changing it is out of scope and would not create independence |
| Parsers, graph, taxonomy, BOM, derating, EDIF | **KEEP** | DIRECT lineage; this *is* the schematic core; replacing is a later engineering program |
| `models.Finding` + normalize/dedupe | **KEEP** + **ISOLATE** | Keep types; route new semantics through `finding_engine` |
| `validate.py` LLM loop | **KEEP** for now; **ISOLATE** provider/skills | Working product; independence = provider + finding contract, not a greenfield reviewer |
| PCB / placement / antenna / finding_engine / KiCad plugin | **KEEP** | NEW Periscope surface |
| `vendor/impedancefinder` | **ISOLATE** + **INVESTIGATE** | Boundary already in `impedance.py`; license unknown |
| Faradworks TOS, privacy, footers, layout authors, Twitter, contact email | **REPLACE** | Operator identity; largest *non-engine* coupling |
| `pinscope_version` / JWT issuer / CORS host aliases | **ISOLATE** then expire | Needed for live data; not the architecture |
| `storage-keys.ts` still writing `pinscopex:` | **REPLACE** (write path) after dual-read | Partial migration bug-shaped |
| Clerk seams (`clerk-theme`, JWKS, admin Clerk API, email) | **ISOLATE**; **REMOVE** only when local auth is the only supported mode | Dual stack |
| `anthropic` dependency, `upload_skills.py`, Console-oriented CLAUDE.md | **ISOLATE**; **REMOVE** later if DeepSeek-only is policy | README already forbids Anthropic |
| GitHub `main` vs pcb-review | **INVESTIGATE** (process) | Merge/publish strategy; do not detach fork |
| PyMuPDF dual license + Python transitives | **INVESTIGATE** | No pip lock |
| ImpedenceFinder license from author | **INVESTIGATE** | Blocker for *clean* third-party story, not for reading code |
| `simple_project` / how-it-works.svg | **KEEP** | UPSTREAM fixtures; rebrand docs separately |
| Billing hook / gateway stubs | **KEEP** signatures; **ISOLATE** comments that imply Faradworks cloud | Open-core seam |
| PinScope *strings* in changelog | **KEEP** | Historical accuracy |

**REMOVE** is empty for Phase 0. Nothing should be deleted on the basis of this audit alone.

---

## 11. Phase 1 sequence (recommended order; not this change)

Phase 1 should increase **independence**, not maximize diff against PinScope.

1. **Land this audit** on a branch that does not rewrite engines (`docs/development/PINSCOPE_AUDIT.md` only).
2. **Branch topology:** decide how GitHub `main` relates to `cursor/pcb-review-plan-44dd` without detaching the fork (merge/PR of product onto `main`, or document that `main` is archival). Until then, every clone is the wrong tree.
3. **Operator identity:** replace Faradworks TOS/privacy/contact/metadata/Twitter/footers with Periscope operator documents; keep AGPL and a factual “derived from Faradworks/Pinscope” attribution (README already has a form of this).
4. **Compatibility fence:** one module/doc for legacy `pinscope_*` keys, JWT issuer, CORS, Docker network names; stop writing new `pinscopex:` storage keys.
5. **Auth ISOLATE:** make the self-host path (local JWT) the documented default; keep Clerk behind a named seam so admin/email do not assume Clerk.
6. **LLM ISOLATE:** document DeepSeek as the supported provider; treat Anthropic SDK + `upload_skills.py` as optional/legacy so CLAUDE.md matches README.
7. **Finding contract:** keep using `finding_engine` as the independence layer on top of `Finding`; do not rewrite `validate.py` in Phase 1.
8. **Vendor license:** obtain an explicit license for ImpedenceFinder (or stop distributing the vendor tree until known).
9. **Python lock:** add a lockfile so transitive licenses can be audited like npm.
10. **Only then** consider isolating parsers/graph behind a narrower Periscope API — a large KEEP surface, not a Phase 1 delete.

---

## 12. Unresolved questions and evidence gaps

1. **Intent of GitHub `main`:** accidental staleness vs deliberate “OSS mirror of upstream + Docker”? No PRs exist to explain it.
2. **Legal operator of periscope.michelebigi.it** vs documents that still say Faradworks, Inc. — this audit cannot assign a legal entity.
3. **ImpedenceFinder license** (author, KiCad cpp port implications). GitHub API `license` is null.
4. **PyMuPDF** AGPL vs Artifex commercial: which grant is used in the VPS deploy?
5. **Python transitive licenses** without a lockfile.
6. **Whether Anthropic is still reachable** if env keys exist despite README (code path exists; runtime not executed here).
7. **Private Faradworks gateway** files mentioned in upstream CLAUDE.md — not in this repo; cannot audit what the parent still replaces in cloud builds.
8. **Trademark** “Pinscope” / “Periscope” / “Faradworks”: search found **use**, not a registration database. No legal conclusion.
9. **Empty-file DERIVED tags** — see §2; raw vs adjusted counts.
10. **`origin` on the analyst clone** included a local `upstream` remote for fetch-only comparison. GitHub fork remotes were not edited; confirm live GitHub still has `parent: Faradworks/Pinscope` after this docs-only PR.
11. **mbparks/pinscope** (Arduino) is a **different project**; zero code overlap observed; ignored.
12. **Exact installed npm/pip versions on production** (`/root/periscope`) were not inspected; licenses are from lock + PyPI JSON as of 2026-09-20.
