From 2f67c2502cc260306ea796d7ef791aa3a3a9f66c Mon Sep 17 00:00:00 2001 From: Claude Date: Mon, 3 Aug 2026 01:47:19 +0000 Subject: [PATCH 1/9] feat: add cryptojacking, home-network intrusion, and stalkerware coverage Adds the detection and remediation content for a household whose Wi-Fi has been broken into, and for the cryptojacking that tends to arrive with it. New modules: - crypto_miner_persistence (macOS/Windows/Linux) finds what restarts a miner after it is killed: launch items, cron, systemd units, Run keys, scheduled tasks, shell profiles, and dropped miner configs. Wallet addresses and stratum arguments are treated as high-confidence evidence; a product name alone is not. - win_crypto_miner_detect gives Windows the live-miner detection that previously existed only for macOS: process command lines, established connections to mining-pool ports, and high CPU as a low-confidence lead. - browser_cryptojacking_check covers in-browser mining, which never shows up in a process list: extension code, startup pages, and hosts-file entries. Blackholed mining domains are recognised as protection, not as a threat. - lan_device_inventory lists the devices actually visible on the network, with OUI vendor labels, and says plainly that a quiet device can be missing. - arp_spoof_check looks for traffic interception: the gateway's address answering for other hosts, duplicate addresses, and multiple default routes. - router_security_audit checks the gateway's exposed admin surface and UPnP, and carries the full router reclaim procedure. - stalkerware_scan separates covert monitoring software from workplace and parental products and from dual-use remote access, and leads its guidance with safety planning rather than removal instructions. Supporting content: shared cryptojacking IOC data, a shared neighbour-table helper, expanded known-bloatware datasets (adware, scareware, bundled miners, OEM trials), and the home_network_intrusion profile and five-phase guide, ordered so the network is reclaimed before the devices are cleaned. rescue.runtime gains load_content_module() so modules can share a helper by path, which works in a source checkout, a pip install, and a frozen bundle. Every fix() here is guidance only, marked ActionKind.GUIDANCE, and every external command and filesystem scan is bounded by a timeout or a cap. Also fixes three pre-existing Python 3.12-only f-strings that made win_malware_indicators and win_bsod_analysis fail to load, and test_module_win_scheduled_tasks_security fail to collect, on the declared minimum Python 3.11.

Decide whether this is a safety situation first + +If the person who may have got in is someone you know — a partner, an ex, a +housemate, a family member — stop and read this before doing anything else. + +Cutting off someone's access tells them they have been found out. If that +person has ever frightened you, the safest order of operations is different +from the technical one, and it is worth getting help planning it. In the US, +the National Domestic Violence Hotline is 1-800-799-7233.

Slow computers, +fans running constantly, a hot laptop doing nothing, unfamiliar devices in the +router's list, logins from places you have not been, someone knowing things +they should not. Note dates if you have them. + +This matters for two reasons: it is what tells you whether the problem is +fixed afterwards, and it is the beginning of a record if this ever becomes a +police report or a legal matter. + +## Step 3: Find a device and a network you can trust + +You will need somewhere safe to change passwords from, and it cannot be a +device on the affected network. A phone on mobile data — with mobile data on +and Wi-Fi switched off — is usually the easiest option. Use it for account +changes throughout this guide. + +Do not change important passwords from a machine you have not yet cleaned. If +something on it is recording keystrokes, you are handing over the new password +as you type it. + +## Step 4: Understand the order and why it matters + +The rest of this guide goes: reclaim the network, then clean the devices, then +rebuild the accounts. + +That order is deliberate. Cleaning a laptop first and then reconnecting it to +a network someone else still controls means starting again. Changing passwords +first, on an unclean machine or an intercepted network, means handing over the +new ones. It is slower to do it in this order and much faster than doing it +twice. diff --git a/guides/home_network_intrusion/phase_1.md b/guides/home_network_intrusion/phase_1.md new file mode 100644 index 0000000..6674748 --- /dev/null +++ b/guides/home_network_intrusion/phase_1.md @@ -0,0 +1,62 @@ +--- +profile: home_network_intrusion +phase: 1 +title: "See Who Is On The Network" +automatable_steps: [1, 2] +human_only_steps: [3, 4, 5] +estimated_time: "45 minutes" +--- + +## Step 1: Inventory the devices on the local network + +Run the profile's local-network checks. `lan_device_inventory` lists every +device that has recently talked to this computer, with the manufacturer behind +each hardware address where it can be identified. + +Two things to know before reading the list. It only shows devices that have +been active recently, so it can be incomplete — the router's own admin page is +the authoritative list. And modern phones deliberately use a different, +randomly generated hardware address on every network, so a phone will not +match the address printed on its box. That is privacy behaviour, not an +intruder. + +## Step 2: Check whether anything is intercepting traffic + +`arp_spoof_check` looks for the specific pattern that traffic interception +leaves behind: one device answering for addresses that belong to others, +usually the router's. + +If it reports gateway impersonation, treat the network as actively monitored. +Stop using it for anything sensitive until Phase 2 is done — no logins, no +password changes, no banking. Switch to mobile data for those. + +Mesh systems and Wi-Fi extenders can produce the same pattern legitimately. If +you have one, that is the likely explanation; confirm it before panicking. + +## Step 3: Name every device on the list + +Go through the inventory one line at a time and say what each device is out +loud: phone, laptop, TV, printer, thermostat, doorbell, games console, smart +plug. Most households are surprised by the count — twenty is normal now. + +For anything you cannot name, unplug or power off a suspected device and +re-run Step 1. The entry that disappears is that device. + +## Step 4: Cross-check against the router's own device list + +Sign in to the router (Phase 2 covers how) and open its list of connected +devices — it may be called Attached Devices, Device List, Client List, or +DHCP Clients. It shows devices your computer has not spoken to, which the scan +in Step 1 cannot see. + +Compare the two lists. Anything on the router's list that you cannot account +for is the thing to focus on. + +## Step 5: Do not bother blocking devices by hardware address + +Most routers offer MAC filtering, and it feels like the obvious answer. It is +not: a hardware address can be changed in seconds, and blocking one only tells +the intruder which address to stop using. + +The change that actually removes everyone you have not authorised is a new +Wi-Fi passphrase, which is Phase 2. diff --git a/guides/home_network_intrusion/phase_2.md b/guides/home_network_intrusion/phase_2.md new file mode 100644 index 0000000..818250f --- /dev/null +++ b/guides/home_network_intrusion/phase_2.md @@ -0,0 +1,88 @@ +--- +profile: home_network_intrusion +phase: 2 +title: "Take The Router Back" +automatable_steps: [1] +human_only_steps: [2, 3, 4, 5, 6, 7, 8] +estimated_time: "1 hour" +--- + +## Step 1: Audit what the router is offering to the network + +Run `router_security_audit`. It checks which administrative services your +router is offering to every device on the Wi-Fi — remote login services, the +admin page, provider management interfaces — and whether UPnP is enabled. + +Everything after this step happens in the router's own settings, because the +settings that decide whether someone can get back in are not visible from +outside it. + +## Step 2: Sign in to the router, ideally over a cable + +Connect a computer to the router with an Ethernet cable if you can, so the +next steps do not travel over a network someone else may be watching. Then +open the gateway address the audit reported in a browser. + +If the admin password is still the one printed on the underside of the router, +assume the router has already been reconfigured by someone else, and read +every setting below rather than trusting any of them. + +## Step 3: Update the firmware first + +Look for Firmware Update, Router Update, or Administration. Install whatever +is offered and let it reboot. + +Do this before anything else. If the router has a known vulnerability, new +passwords do not help — the way in was never the password. + +## Step 4: Change the admin password and the Wi-Fi passphrase + +Two different passwords, both long, neither used anywhere else: + +- The **admin password** protects the router's settings. +- The **Wi-Fi passphrase** is what devices use to join. + +Set the wireless security mode to WPA3. If the router does not offer it, +WPA2-AES (sometimes shown as WPA2-PSK AES) is acceptable. Never WEP, never +WPA/TKIP, never open — those are broken and can be cracked in minutes by +someone parked outside. + +## Step 5: Turn off WPS + +WPS lets a device join using an eight-digit PIN instead of the passphrase, and +that PIN can be broken offline. Leaving it on makes the strong passphrase you +just set irrelevant. Turn it off. + +## Step 6: Turn off remote administration, and check the DNS servers + +Find Remote Management, Remote Access, Web Access from WAN, or cloud +management, and turn it off. The router's settings should only be reachable +from inside the house. + +Then open the Internet or WAN page and look at the DNS servers. They should be +your provider's, or a resolver you deliberately chose (for example 1.1.1.1 or +9.9.9.9). Anything else means someone redirected every device in the house to +a name server they control — every phone, TV, and laptop, without touching any +of them. Reset it if it is not what you expect. + +## Step 7: Clear out port forwarding, DMZ, and the guest network + +Delete every port-forwarding rule you did not create yourself, and switch off +any "DMZ host". These are open doors from the internet to a specific device +inside the house, and UPnP can create them automatically on a program's +request. + +Check the guest network too.

Ordinary + software that gives someone complete control of the screen. Common leftovers + from "tech support" phone scams. +- **Adware and fake cleaners**, which are a nuisance rather than surveillance, + but tend to arrive by the same route. + +## Step 5: Remove in the right order + +For each thing found: + +1. Record it first — a screenshot, the file path, the date. +2. Remove the startup entry, then reboot. +3. Delete the program itself. +4. Re-run the checks. + +If something reappears after a reboot, stop.

and profile MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds a six-phase guide that doubles as a recovery checklist — `rescue guide identity_theft_recovery` prints the outstanding steps and `--complete ` marks them off, so progress survives across the weeks this actually takes. The phases are ordered the way recovery works rather than the way it feels: 0. The first hour — start a recovery log, write down what is known, and deal with money that has already moved (reporting windows for unauthorised debit charges are short). 1. Confirm the device is not the leak — the only automatable phase, because changing passwords on a machine with a keylogger hands them straight back. Also covers email forwarding rules and carrier port-out locks, which both survive a password change. 2. Freeze — all three credit bureaus plus Innovis, NCTUE, and ChexSystems, which is where phone contracts and bank accounts get opened. 3. Report — IdentityTheft.gov first, because the FTC identity theft report is what unlocks the §605B block and the seven-year extended alert. Then police, IRS/state tax, SSA, CFPB, and the channels specific to SIM swap, medical, criminal, child, and deceased-relative identity theft. 4. Dispute — the distinction between a dispute (30 days, contestable) and an identity theft block (four business days, backed by the FTC report), plus the follow-up schedule for accounts that reappear via a new collector. 5. Monitor and rebuild — the long tail, and what recurrence looks like. The profile pairs the guide with the twelve existing modules that answer the one technical question here: is this device leaking credentials. It claims no automation for anything that happens at a bank or a government agency. US-first, with equivalents for the UK, Canada, Australia, and the EU in phase 2, and free case-managed support services named in phase 5. Also regenerates the integrity manifest for the runtime.py change in the previous commit, which was making every launch print a tamper warning.

From here on, every call and every letter gets one line: the date, +the organisation, the person's name, what they said, and any reference number +they gave you. + +This feels like busywork on day one. It is the single most useful thing you +will do. Recovery runs on being able to say "I reported this on the 4th, my +reference is X, and I was told Y" — often months later, to someone who has no +record of the previous conversation. + +## Step 2: Write down what you already know + +What made you realise? A charge you did not make, a letter about an account +you never opened, a rejected tax return, a debt collector, a denied +application, a breach notification. Note the dates and the amounts. + +You will be asked to repeat this story to a dozen organisations. Having it +written down once means it stays consistent, and consistency matters when +somebody is deciding whether to believe you. + +## Step 3: Know what identity theft is not your fault + +You did not cause this by clicking something. The overwhelming majority of +identity theft starts with data that a company lost — a breach, a stolen +laptop, a contractor's database. Reconstructing what you "should have done +differently" burns the energy you need for the next four phases. + +There is also a practical reason not to blame yourself: people who feel +foolish tend to under-report, and under-reporting is what costs money later. + +## Step 4: Understand the order, and why it is this order + +The rest of this guide runs: check the device, freeze the accounts, file the +official reports, dispute the damage, then monitor. + +Freezing comes before reporting because a freeze stops new damage while the +paperwork moves. Reporting comes before disputing because the official report +is what obliges credit bureaus and creditors to act — dispute letters sent +without one get form-letter replies. + +## Step 5: Decide what to do about the immediate money + +If money has actually left an account, that is the one thing that does not +wait for the sequence. Call the bank's fraud line — the number on the back of +the card, not one from a search result or an email — and say the words +"unauthorised transaction" and "fraud". + +Timing rules are real and short. In the US, unauthorised debit card charges +are capped at $50 if you report within two business days of noticing, and can +rise to $500 or the whole balance after that. Credit cards have stronger +protections than debit cards, which is the practical reason to use a credit +card online. diff --git a/guides/identity_theft_recovery/phase_1.md b/guides/identity_theft_recovery/phase_1.md new file mode 100644 index 0000000..6271227 --- /dev/null +++ b/guides/identity_theft_recovery/phase_1.md @@ -0,0 +1,60 @@ +--- +profile: identity_theft_recovery +phase: 1 +title: "Make Sure The Device Is Not The Leak" +automatable_steps: [1, 2, 3] +human_only_steps: [4, 5] +estimated_time: "45 minutes" +--- + +## Step 1: Scan for monitoring and malware on this device + +Run the profile's device checks: `stalkerware_scan`, `keylogger_indicators`, +`malware_scan_indicators` or `win_malware_indicators`, `suspicious_processes` +or `win_suspicious_processes`, and `process_scanner`. + +The point is narrow.

Once you have the FTC identity theft report +from Phase 3, you can upgrade to an extended alert lasting seven years — which +is why this step is worth revisiting after the next phase. + +## Step 4: Call every bank and card issuer, not just the affected one + +For each institution: report the fraud, ask them to add a fraud flag to your +file, and ask what internal verification they can add — a passphrase, a +call-back requirement, or a note that in-branch identification is required. + +Ask each one directly: "Are there any accounts, cards, or applications on file +that I have not told you about?" That question surfaces accounts opened in +your name at a bank you already use, which no credit report search will show +you as quickly. + +## Step 5: Change passwords on financial and government accounts + +Bank, card issuers, payment apps, brokerage, tax authority, benefits, pension, +insurance. New unique password each, two-factor authentication on each, from a +device you cleared in Phase 1. + +Where the account offers it, change the security questions too. Mother's +maiden name and first school are exactly the details that get bought in bulk. + +## Step 6: Reclaim the mail + +Physical mail is still a live channel for identity theft. Check that no +change-of-address request has been filed in your name — in the US, the Postal +Service sends a confirmation letter to the old address when one is filed, so +look back through recent post for one you did not request. + +Sign up for the postal service's daily mail preview if it offers one, so you +can see what should be arriving.

Medicare fraud: 1-800-MEDICARE. +- **Criminal identity theft** (someone arrested using your name) — contact the + arresting agency and the court directly; ask about an identity theft + passport or clearance letter. +- **A child's identity** — the bureaus will create and immediately freeze a + minor's credit file on request, free of charge. Check for one; a child + should have no credit file at all. +- **A deceased relative's identity** — send a copy of the death certificate to + all three bureaus and ask for the file to be flagged "deceased — do not + issue credit". + +## Step 7: Update the log, and file everything in one place + +Add every reference number from this phase to the log: FTC report number, +police report number, IRS and SSA case numbers, CFPB complaint number. + +Keep one folder — paper or a single encrypted archive — with the FTC report, +the police report, and your log.

Each guide now ends with a dedicated reference phase. identity_theft_recovery phase 6 covers free case-managed help (Identity Theft Resource Center, the AARP helpline, the DOJ elder fraud hotline, IDCARE, the Access Now digital security helpline), the official reporting channels, all six credit bureaus and databases that accept freezes, abuse-specific support including coerced debt, free legal aid, and non-US equivalents. home_network_intrusion phase 5 covers abuse support first — because when the intruder is someone known, the safety plan changes the order of the technical work — then free incident response, where to report an intrusion, a pointer to the identity theft guide when accounts are involved, and how to tell whether a router is worth keeping. Both open with the same warning: search results for support numbers are bought by scam call centres, and someone mid-recovery is exactly who they want. Type the domain, use the number on the card, and nothing legitimate is ever paid for in gift cards. That warning is worthless below the list, so it is step 1. stalkerware_scan's safety guidance gains the same country-by-country numbers, plus a note not to look them up from the monitored device — browsing history is one of the things that gets reported. A test asserts the scam-helpline warning stays first in the resources phase, and the step-title check caught one heading too vague to work as a checklist item.

The renderer escapes all scan output today, so there is no live injection path — but the URLs it opens come from permissions-content.json, a data file the content-update mechanism is designed to replace. An unrestricted channel therefore turns "attacker influences shipped content" into "attacker launches local files and registered protocol handlers", which is a poor trade for a tool people run on machines they already suspect are compromised. The walkthrough only ever needs OS settings panes, so the check is an allowlist of scheme prefixes rather than sanitisation — allowlists do not have parser differentials. Matching is startsWith, so a permitted scheme embedded later in a file:// URL does not qualify it. Also sets sandbox: true, denies window.open, and blocks navigation: the renderer only ever loads the bundled local page and has no reason to do any of the three. The predicate lives in its own module so it is testable without booting Electron, and package.json gains the "test" script the desktop app was missing.

That keyword argument reached pathlib in 3.13, so on 3.11 and 3.12 every one of these raises TypeError at runtime — these modules did not work at all on two of the three supported versions, and roughly 45 tests were failing because of it. rescue.fsbounds gains is_file_nofollow / is_dir_nofollow, which get the same no-follow semantics from os.lstat on every supported version and return False rather than raising on a missing or unreadable path, matching how Path.is_file swallows OSError. All 30 sites now go through them. rescue/fsbounds.py's own follow_symlinks arguments are deliberately untouched: those are os.DirEntry objects from os.scandir, where the keyword has been valid all along. user_profile_size additionally needed a testability seam. Its tests mocked only subprocess and then walked the real /Users, so they asserted against whatever happened to be on the host — passing on a developer's Mac and failing anywhere else, which is how the follow_symlinks breakage stayed hidden. The traversal roots are now attributes a test can point at a fixture tree, and the tests build one, covering the skip rules, a missing /Users, and a failing du. They no longer touch the host filesystem. Also drops CliRunner(mix_stderr=False) in test_cli_scan_json: click >= 8.2 removed the parameter and now always captures stdout and stderr separately, which is precisely what these tests want to assert.

charset=UTF-8 Content-Transfer-Encoding: 8bit The remaining failures were not flaky. Each was a test that silently depended on the machine it ran on, so the suite only passed on one developer's macOS box: - notification_center_check (7), kext_audit (1), appleid_security_check (1): each module checks a real path under ~/Library or /Library and returns early if it is absent, so on any non-macOS host check() short-circuited before the mocked subprocess was ever reached. The traversal roots are now attributes a test can point at a fixture; appleid additionally needed a real plist on disk, since patching plistlib.load still left open() to fail. - win_safe_mode_check (2): a time bomb. The uptime fixtures were absolute dates chosen to be "5 days ago" when written; real time moved past them and the 5-day fixture aged into a >30-day uptime, tripping the high-uptime warning it asserts is absent. Fixtures are now computed relative to now. - disk_permissions_repair (1): asserted ownership against a hardcoded uid 501, so it only passed as a typical macOS user and failed as root. It now derives the uid from the process, with /usr/local given a separate non-root uid — "correctly owned" means the running user for a home directory but explicitly *not* root for /usr/local, which one uid cannot express when running as root. - update/test_verify (1): the test signs a tag with `git tag -s` without pinning gpg.format. git honours the ambient setting, so on a machine configured for SSH commit signing it produced an SSH signature while the test asserted on the GPG path. Pinned to openpgp. The verification code itself is correct here — git verify-tag detects the signature type on its own — so only the test changed; no trust check was weakened to get this green. kext_audit's `find` call also gained the timeout it was missing. Full suite: 3405 passed, 0 failed (was 64 failed, 3341 passed).

The recorded fix deleted the references and relabelled the steps human-led, so the capability was never actually built. These are the real modules. All three are read-only and guidance-only (ActionKind.GUIDANCE, no auto_apply), and none of them reads a secret: no vault, keychain item, cookie database, token value, or SSH key material. Their filesystem roots are class attributes so the tests run off a fixture tree rather than the host. password_manager_check — detects installed managers (macOS app bundles, Windows uninstall registry) and browser profiles that would otherwise be holding the passwords. Browser storage is flagged only when no dedicated manager is present, since that is the posture worth changing. Prefix matching stops at the first hit so KeePassXC is not also reported as KeePass. twofa_audit — the honest one. A local tool cannot tell whether 2FA is enabled on your accounts; that lives at the provider and confirming it means signing in. So it reports what it can observe (authenticator apps, locally recorded platform 2FA) and states account status as NOT CHECKED. Crucially, absence of evidence is reported as unknown, never as "two-factor is off" — an unverified security verdict presented as fact is worse than an admitted gap, and there is a test asserting it can never collapse to False. session_revocation_scan — the post-compromise question: what is still logged in. Counts browser profiles (each holds its own cookies), device-configured accounts, and authorised SSH keys, all of which survive a password change. The guidance puts the password change *before* the sign-out, because revoking first just lets whoever has the password back in, and that is the step people get backwards. A test asserts key material never reaches a finding. Registry now discovers 275 modules; catalog and remediation-code gates pass.

Three of those rows were module-shaped and had no coverage at all. code_signature_audit — the answer to P2's own complaint that "file-name and keyword checks create false positives". Verifies signatures via codesign/spctl and Get-AuthenticodeSignature. Severity is chosen to stay defensible: CRITICAL only for a signature that is present and broken, because a binary modified after signing has no innocent reading; WARNING for unsigned software in a system-wide location; nothing at all for unsigned software in the user's own ~/Applications, which would be pure noise. Verification is slow, so the scan is capped — and the INFO finding states the cap and whether it was hit, because a result that silently examined 40 of 300 apps while implying a full audit is worse than none. security_baseline_diff — P2's "a single snapshot cannot identify what changed". Records persistence, listening ports, browser extensions and protection states, then reports only additions and only protections that went on -> off. The asymmetry is deliberate: reporting removals and re-enablements symmetrically buries the four changes that matter under forty that do not. Two properties are tested rather than assumed — every finding states the trust-on-first-use limit (a machine already compromised at baseline has that baked in), and a protection that merely became unqueryable is never reported as disabled. evidence_bundle — P2's "repair can destroy the information needed to understand a compromise". Runs at priority 90 so it is considered before the modules that propose fixes. check() deliberately writes nothing; creating files is a real effect and belongs behind an explicit human decision. The bundle it can write is redacted by construction, hashes every item, and records what it omitted and why so a gap is visible to the recipient rather than looking like an absence of evidence. It has no network path. A test asserts no collection command can read a credential store. digital_security_reset now includes these plus the three account-recovery modules, with evidence_bundle first. Its description no longer claims the password-manager, 2FA and session steps are entirely human-led, because the device-side half of each is now real — while being explicit that changing passwords, enabling 2FA and revoking sessions still happens at the provider. Also regenerates rescue/security/integrity_manifest.json, which was stale on main: verification reported 8 tampered and 5 added files, so every launch printed a tamper warning. It verifies clean now. Registry discovers 278 modules. Full suite: 3503 passed, 0 failed.

On main it reported 8 tampered and 5 added files, so every launch printed a tamper warning. The regeneration was real but happened on a different lineage. - P0#8 was recorded as done. The profile was made valid by deleting the three module references, not by building the modules. - The baseline was recorded as 3094 passing. It was 64 failed / 3341 passed, with one file that did not parse on the declared minimum Python. The corrections are appended as a dated section rather than edited in place, so what was previously believed stays legible. Also records the current numbers for the two large outstanding migrations, both of which have grown since the roadmap was written (756 subprocess.run sites with 0 through the bounded runner, 435 without timeouts; 169 modules with no emits_codes), and the absence of CI as the gap that let the Python 3.11 breakage ship.

It did not verify clean on `main`.** `verify_package_integrity` reported +8 tampered and 5 added files, so startup verification failed and every launch +printed a tamper warning. The regeneration was real, but it happened on a +different lineage; `main`'s own commits then added `remediation.py`, +`serialize.py`, `threat_map.py`, and two TUI screens without regenerating. +Regenerated here, and it now verifies clean. + +**P0#8 (security-reset profile) was recorded as DONE.** It was made *valid* by +deleting the references to `password_manager_check`, `twofa_audit`, and +`session_revocation_scan` — the profile stopped naming modules that did not +exist, but the capability was never built. Those three modules now exist and the +profile references them again. + +**The test-suite baseline was recorded as "3094 passing".** The suite was not +green: it was 64 failed / 3341 passed, and one file did not even parse under the +declared minimum Python. See below. + +## Python version support was broken, not partially broken + +`pyproject.toml` declares `requires-python = ">=3.11"`. On 3.11: + +- 3 files failed to parse at all (PEP 701 nested-quote f-strings, and a + backslash inside an f-string expression). Two were shipped modules, so module + discovery broke. +- 30 call sites across 16 modules passed `follow_symlinks=` to + `pathlib.Path.is_file()` / `is_dir()`. That keyword arrived in **3.13**, so + every one raised `TypeError` at runtime. Those modules did not work on two of + the three supported versions. + +Both are fixed; `rescue.fsbounds` now exposes `is_file_nofollow` / +`is_dir_nofollow` with the same semantics on every supported version. + +**Nothing was catching this.** There is no `.github/` directory and no CI. A +matrix that actually ran the suite on 3.11 would have caught the largest defect +in the tree. This is the highest-value remaining infrastructure gap. + +## The 64 failures were environment coupling, not flakiness + +Every one was a test that silently depended on the machine it ran on, so the +suite only passed on one developer's macOS box: + +- Modules that check a real path under `~/Library` or `/Library` and return + early if absent, so `check()` short-circuited before the mocked subprocess was + reached (`notification_center_check`, `kext_audit`, + `appleid_security_check`). +- A time bomb: `win_safe_mode_check` used absolute dates chosen to be "5 days + ago" when written. Real time moved past them and the fixture aged into a + >30-day uptime, tripping the warning it asserts is absent. +- `disk_permissions_repair` asserted ownership against a hardcoded uid 501, so + it only passed as a typical macOS user account. +- `test_cli_scan_json` used `CliRunner(mix_stderr=...)`, removed in click 8.2. +- `update/test_verify` signed a tag without pinning `gpg.format`, so on a host + configured for SSH commit signing it produced an SSH signature while asserting + on the GPG path. **No trust check was weakened to green this**; the + verification code was correct and only the test changed. + +The pattern is now a convention: a module's traversal roots are class attributes +so tests can point them at a fixture tree. + +Full suite: **3503 passed, 0 failed.** + +## Planned modules — resolved + +"Planned but missing" was resolved against the roadmap, not guessed. Profiles, +guides, and the threat map reference no missing modules, and every module named +in `docs/superpowers/plans/` exists. Two sources yielded real gaps, both now +closed: + +| Module | Source | Why it exists | +| --- | --- | --- | +| `password_manager_check` | P0#8 | Named, never built | +| `twofa_audit` | P0#8 | Named, never built | +| `session_revocation_scan` | P0#8 | Named, never built | +| `code_signature_audit` | P2 "Trust and reputation verification" | No signature validation existed | +| `security_baseline_diff` | P2 "Baselines and differential scans" | No baseline capability existed | +| `evidence_bundle` | P2 "Evidence collection and forensic handoff" | Nothing preserved evidence before repair | + +Registry now discovers **278** modules.

The counts have **grown** since +the roadmap was written, which is worth knowing before scheduling them: + +- **P0#7 command-runner migration has not started.** 756 `subprocess.run` calls + in modules, **0** routed through `rescue.command.run`, 435 with no timeout. + The roadmap counted 744 and 395. +- **Remediation codes are ~38% migrated.** 169 of 272 pre-existing modules + declare no `emits_codes`; 30% of `Finding()` constructions set `code=`. + (`tests/test_module_code_consistency.py` does guard the ones that do.) +- **No CI**, as above. + +Verified healthy, for balance: `auto_apply = True` appears in **zero** modules, +so auto mode genuinely is read-only as P0#5 intends; there are no +`NotImplementedError` stubs or placeholder TODOs; the only skipped tests are +correctly conditional on `gpg` being available; and both `setup.py` and +`rescue.spec` glob the content directories, so new modules ship without +packaging changes.
