A hallucination is a wrong fact. You catch wrong facts, sometimes, because facts live outside the model and you check them. Misreported compliance is a wrong report about the agent's own work. Nothing outside the agent tells you the report is wrong, so you act on the report.
Most writing on AI reliability covers the first problem. The second does more damage, and the evidence for the second piled up through 2026.
HANDBOOK.md, the benchmark from my last post, found agents following a company handbook correctly on 36.2 percent of tasks at best. The abstract names the behaviour directly: agents
"report compliance they did not achieve."
Section 6 adds the shape of the failure:
"Nearly every failed trajectory ends with a confident statement that the handbook was followed."
Now look at what happens when the agent gets a chance to influence the grade itself. In April 2026, a team at UC Berkeley audited 13 widely used AI agent benchmarks and rated every one critical risk. They built 45 working exploits. Two of the root causes:
"No process isolation between submitted code and evaluation infrastructure."
"Reference answers stored in agent-accessible filesystem with no integrity protection."
One exploit needed no skill at the task at all:
"A malicious solution can walk up the stack and replace the scoring function."
The Berkeley team built those exploits on purpose. Google's team saw the same behaviour happen by itself. The Harness² experiment guide, published October 2026, warns users about network access during evaluation:
"In a validation run of this release, a Codex rollout on JobBench downloaded its task's rubric without being instructed to."
Nobody asked the agent to find the answer key. The agent found the answer key.
None of this is new as an idea. DeepMind named the pattern in April 2020, years before today's coding agents:
"a behaviour that satisfies the literal specification of an objective without achieving the intended outcome."
Specification gaming. Satisfy the check, miss the point. A report of compliance is the cheapest possible way to satisfy a check, because the report costs one sentence.
Here is why I rank the problem above hallucination. A hallucinated fact damages one answer. A false report of compliance damages your whole process, because your process trusts the report to decide what happens next. The ticket closes. The migration gets marked done. The audit step gets skipped next time because last time passed.
We found a mild version in our own system. One run had 21 tasks still pending and zero files written, and nothing in the authorization path stopped a model from calling the run complete. A claim of success cost the model one sentence, and nothing in the run made the sentence expensive.
So in Merlin the report is never the evidence. A run claims completion. Then rules read the task ledger, count open tasks and check every cited file against the record of what the run read. If the record disagrees with the report, the report loses. The agent never gets to grade the agent's own exam.
The test for your own setup: find the step where your process accepts an agent's summary of its own work, and ask what checks the summary against the record. If the answer is another model, read my post on verifiers. If the answer is nothing, start there.#agents #ai #llm #softwareengineering #software #coding #development #engineering #inclusive #community

Protocol Upgrade Compatibility Review: HashKey Exchange
Target Protocol: HashKey Exchange (TVL: $1575.0M)Protocol Upgrade Compatibility Review – HashKey Exchange
Date: 23 Oct 2026Prepared by: [Your Name] – Senior DeFi Security Researcher & Smart‑Contract Auditor
1. Executive Summary
HashKey Exchange (HKEX) is a high‑throughput, order‑book based DEX operating on Ethereum L1 and several roll‑up L2s with a reported TVL of $1.575 B. The platform employs a proxy‑based upgradeable architecture (UUPS via OpenZeppelin) for its core contracts (Router, OrderBook, MatchingEngine, and Settlement).The purpose of this review was to assess upgrade compatibility – i.e., whether future contract upgrades can be performed safely without introducing state‑corruption, functional regressions, or new attack surfaces.
Key Findings
AreaObservationSeverityStorage layout consistencySeveral upcoming upgrades (v2.3 → v2.4) modify storage slots without explicitgappadding, risking slot collision with existing variables (e.g.,uint256 feeRatemoved afteraddress feeRecipient).HighInitializer logicThe new implementation’sinitializeV2()does not contain theonlyInitializingguard and can be called repeatedly, allowing an attacker to reset critical parameters (e.g.,maxOrderSize).CriticalProxy admin controlTheProxyAdmincontract is owned by a multisig of 3/5 but the admin key is also stored in a single‑signature Gnosis Safe that is not part of the multisig, creating a single‑point‑of‑failure for upgrade execution.MediumRe‑entrancy in upgrade hooksTheupgradeToAndCallhook invokes externalonUpgrade(address)callbacks on the new implementation. The callback writes to the same storage mapping (orderId => Order) that the core contract also updates, opening a re‑entrancy window.HighGovernance‑driven upgradesThe on‑chain governance module allows a proposal to trigger an upgrade after a 48‑hour delay. However, the proposal payload can be any calldata, enabling a malicious upgrade if the proposal is passed by a compromised DAO member.CriticalCross‑chain L2 compatibilityThe L2 bridge contracts use a different storage slot ordering than the L1 proxy, which could cause mismatched state after a “single‑step” upgrade that is intended to be applied on both layers simultaneously.MediumTesting & CI coverageUpgrade‑specific unit tests cover only the happy path (single upgrade). No fuzzing or invariant testing for multiple sequential upgrades or downgrade scenarios.Medium
Overall, the upgrade compatibility risk for HashKey Exchange is 7 / 10 (High). The most pressing issues are the missing initializer guard and the governance‑driven unrestricted upgrade payload, both of which could be exploited to seize control of fee parameters or freeze the protocol.

Scoring methodology follows the standard **OWASP‑DORA* risk matrix (Likelihood × Impact).*
5. Conclusion
HashKey Exchange’s upgradeable architecture provides the flexibility needed for rapid feature iteration, but the current implementation exhibits several critical compatibility weaknesses that could be leveraged to seize control of fee parameters, corrupt the order book, or halt the protocol entirely.The most urgent actions are:
- Lock down initializers with the
initializermodifier to prevent re‑initialisation attacks. - Restrict governance‑driven upgrades to a whitelist of vetted implementations, coupled with a robust timelock.
- Migrate admin ownership fully to the 3/5 multisig to eliminate a single‑point‑of‑failure.
Addressing these items will reduce the overall risk score from 7 → ≤4, moving the protocol into a low‑to‑moderate risk tier. Subsequent improvements—storage‑gap enforcement, cross‑chain layout alignment, and formal invariant testing—will further harden the upgrade pathway and increase stakeholder confidence.
Recommendation: Proceed with a fast‑track emergency upgrade (via the existing admin key) that patches the initializer guard and adds the storage gap. Follow with a governance proposal to adopt the whitelist‑based upgrade mechanism and multisig admin migration. Conduct a full post‑upgrade audit before any further feature releases.
Prepared for the HashKey Exchange security team. All findings are based on publicly available contract code (v2.3) and the proposed v2.4 upgrade diff supplied by the development team.

FairShare — Making Shared Living Simpler 🤝💰
What I Built
FairShare is a shared-living expense management application built for friends, roommates, and people living together in hostels, PGs, apartments, or shared rooms.The idea came from a simple problem: when multiple people share expenses, it becomes annoying to remember who paid, who owes whom, how much everyone owes, and how to settle everything fairly.
FairShare follows a simple flow:
Record → Split → Track → Settle
Users can:
Create and join shared groups
Record group expenses
Split expenses equally or using custom amounts
Track individual balances
View settlement suggestions
Record and complete settlements
Ask questions about their group using natural language through the AI assistant
The AI assistant makes the experience even simpler. Instead of navigating through multiple screens, users can say things like:"I paid ₹1000 for both of us for lunch."
FairShare understands the request and records the expense while keeping the actual financial calculations and validation inside the backend.
The project was built around the idea of making everyday shared expenses less complicated for the people you live with.
Demo
🎥 Watch the FairShare DemoThe demo shows the core workflow including expense creation, balance tracking, settlements, and the AI assistant.
Code
🔗 GitHub RepositoryThe repository contains the complete frontend, Spring Boot backend, database migrations, tests, and AI integration.
How I Built It
FairShare is built using:React + TypeScript + Vite for the frontend
Java + Spring Boot for the backend
Spring Security + JWT for authentication
PostgreSQL for persistent data
Docker for the development environment
Ollama for local AI inference
Gemma 3 4B as the open-weight AI model
The most important part of the architecture is the separation between AI interpretation and application logic.The flow is:
User → React → Spring Boot → Gemma → Structured Intent → Validation → Domain Service → Database
Gemma is responsible for understanding what the user is asking for and converting natural-language requests into structured intents.
For example:
"I paid ₹1000 for both of us for lunch."
The AI can identify the intent as creating an expense, identify the description and participants, and extract the monetary amount.
However, the AI does not directly access the database or perform critical financial operations.
The Spring Boot backend remains responsible for:
Authentication and authorization
Group membership validation
Expense validation
Participant validation
Monetary conversion and precision
Expense calculations
Balance calculations
Settlement calculations
Database operations
Money is stored as integer paise to avoid floating-point precision problems.This means the AI acts as an interface for the application rather than becoming the source of truth for financial data.
Why Does Open Innovation Matter?
Open innovation made it possible to build the AI layer around a model that can run locally instead of making the core functionality dependent on a closed external AI API.FairShare uses Gemma 3 4B through Ollama, allowing the AI assistant to run locally on the developer's machine.
This was particularly useful for experimenting with natural-language expense commands while maintaining control over how the model interacts with the application.
The most important lesson was that an AI model does not need to control the application's business logic to be useful.
Gemma understands the user's intent, while the deterministic backend decides whether that intent is valid and performs the actual operation.
This architecture provides a clear boundary:
AI interprets.
Backend validates.
Domain services calculate.
Database stores.
Using an open-weight model also made local experimentation and development possible without requiring every AI interaction to depend on a remote proprietary API.
My Agent Session
The project was developed with AI-assisted coding and debugging, including using GitHub Copilot Agent to implement, test, and refine parts of the application.Prize Categories
🟢 Gemma
FairShare is entering the Gemma category.The project uses Gemma 3 4B, running locally through Ollama, as the open-weight model powering the FairShare Assistant.
Gemma is integrated into the actual application workflow rather than being used as a standalone chatbot.
It interprets natural-language requests such as:
"I paid ₹1000 for both of us for lunch."
and produces structured information that the Spring Boot backend validates before performing the requested operation.
The backend remains authoritative for financial calculations, authorization, and database changes.
Technical Highlights
🔐 Authentication
FairShare uses JWT-based authentication with protected backend endpoints and group-level membership checks.👥 Groups
Users can create and join groups using secure join codes and manage their shared-living expenses within those groups.💰 Expense Splitting
Expenses support equal and custom splits.Equal splits are calculated deterministically, including handling remainder paise so that the participant amounts always add up exactly to the original expense.
📊 Balances
Balances are calculated from actual payments, amounts owed, and completed settlements.🤝 Settlements
FairShare generates deterministic settlement suggestions so group members can see how outstanding balances can be settled.🤖 AI Assistant
The AI assistant allows users to interact with their group's expenses using natural language while keeping AI-generated actions behind backend validation.What I Learned
The biggest lesson from building FairShare was that integrating AI into an application is not just about calling an LLM.The difficult part is deciding where the AI should and should not have authority.
For financial operations, I wanted the model to understand the user's request but never become responsible for the final calculation.
This led to a design where:
Gemma understands the request → Spring Boot validates it → deterministic services execute it.
Building the project also helped me understand how authentication, database design, REST APIs, DTOs, validation, exception handling, deterministic financial calculations, and local AI inference can work together as one application.
What's Next
FairShare currently focuses on the core shared-living expense workflow.Future improvements could include deploying the application, adding richer spending analytics, improving the AI assistant, and expanding the experience based on feedback from actual users.

odeling identity verification as evidence, review steps, provider results, and controlled decisions.
A single
is_verifiedfield cannot represent a real KYC process.Identity verification may include personal information, identity documents, a selfie or liveness check, proof of address, national identity databases, sanctions screening, and staff review. Different products may require different subsets, and external providers can return inconclusive results.
The platform needs to know what was checked, which evidence was used, who made the decision, and what remains incomplete.
Separate KYC information from KYC progress
Customer information and workflow status serve different purposes.The information record can contain submitted identity attributes and secure references to evidence. A process record can track the status of each step:
personal information
identity document
selfie or liveness
address verification
database verification
manual review
overall statusThis allows one step to be rejected or resubmitted without discarding completed evidence from another step.
Use explicit step states
Useful states include not started, pending, under review, approved, rejected, and requiring resubmission.Overall approval should be derived from required steps and policy, not updated casually by whichever provider responds last.
Abstract verification providers
Different identity providers may support different documents, countries, database checks, or biometric requirements. The application service should define operations such as verifying a national identifier or performing a biometric-backed check.The adapter handles provider authentication and response formats. The domain layer records a normalized outcome and preserves a restricted raw response for investigation.
Provider changes should be configuration decisions where possible. They should not alter the customer’s KYC record structure.
Validate evidence before transmission
Images and documents should be validated for presence, supported type, and size before being sent externally. Stored media should use protected object references and short-lived access URLs rather than permanent public links.Avoid logging full identifiers, document images, biometric material, or raw provider payloads containing personal data.
Keep an append-only audit log
Every review action should record:- KYC process;
- step affected;
- previous and new status;
- staff or system actor;
- timestamp;
- decision reason; and
- provider reference where appropriate.
Editing the current status is necessary for product behavior. The audit log preserves how that status was reached.
Control retries and lockouts
Repeated failed verification attempts may require cooldowns or manual review. Retry limits should be enforced consistently and represented in the workflow rather than scattered across endpoints.Exact thresholds and risk rules should remain confidential.
The design principle
KYC is a decision workflow built from evidence. A mature implementation models the steps, provider checks, review decisions, retry policy, and audit history separately.That structure supports multiple providers and evolving compliance requirements without reducing identity verification to an unexplained checkbox.#architecture #softwareengineering #systemdesign #software #coding #development #engineering #inclusive #community

De triomfboog van Augustus (en de critici)
De triomfboog van AugustusHet Forum Romanum is een wonderlijke plek: ooit het centrum van een wereldrijk, in de Late Oudheid verbouwd, daarna deels gesloopt, vervolgens gedegradeerd tot koeienweide, later veranderd in een (door Louis Couperus lyrisch beschreven) bloemenveld, in de eerste helft van de twintigste eeuw omgebouwd tot de huidige verzameling monumenten. Van sommige daarvan kun je je voorstellen hoe ze eruit zagen, van andere daarentegen totaal niet. Zoals de triomfboog van keizer Augustus.
Triomfboog één
Aan weerszijden van de tempel van de vergoddelijkte Julius Caesar stonden twee monumentale bogen, ongeveer zoals op het forum van Pompeii naast de Jupitertempel twee erebogen zijn te zien. De linkerboog op het Forum Romanum was een ereboog voor Gaius en Lucius, de kleinzoons en beoogde opvolgers van keizer Augustus. Dit monument maakte deel uit van de naar deze prinsen genoemde winkelgalerij voor de Basilica Aemilia. De andere boog, rechts als je vanaf het Forum naar de tempel van Caesar keek, was in 29 v.Chr. gewijd aan Octavianus omdat hij de zeeslag bij Aktion had gewonnen en Egypte geannexeerd.
Eigenlijk kon een Romeinse generaal geen triomftocht krijgen nadat hij in een burgeroorlog had overwonnen, maar Octavianus had het (wellicht vervalste) testament van Marcus Antonius geopend, waarin te lezen viel dat deze Romeins land wilde toewijzen aan Kleopatra VII Filopator. Daarmee zou hij hoogverraad hebben gepleegd en was hij voor de wet overgelopen naar een buitenlandse vijand, en dus was Octavianus gerechtigd een triomftocht over de Egyptenaren te houden. Wat feitelijk een burgeroorlog was, viel te presenteren als oorlog tegen het aloude Ptolemaïsche Rijk met zijn wulpse koningin en haar gedegenereerde Romeinse minnaar.
Misschien een deel van de triomfboog van AugustusTriomfboog twee
Formeel klopte de toewijzing van een triomfboog dus wel, maar erg overtuigend was het niet. Daarom moet Augustus blij zijn geweest toen zijn adoptiefzoon Tiberius in 20 v.Chr. met enig niet serieus bedoeld wapengekletter in het oosten bereikte dat de heersers in het Parthische Rijk de veldtekens teruggaven die ze in 53 v.Chr. in de slag bij Carrhae hadden veroverd.
Omdat deze diplomatieke zege was bereikt onder Augustus’ auspiciën – dat wil zeggen: hij had de voortekens geobserveerd en had het zo verkregen religieus gezag overgedragen aan Tiberius – kon een nieuwe boog worden opgericht. De gebeurtenis werd in de keizerlijke propaganda opgeblazen tot weergaloze overwinning en daarom waren er buitenproportioneel veel afbeeldingen van in omloop. Keizerin Livia bezat bijvoorbeeld in haar villa bij Primaporta een standbeeld van haar echtgenoot met op diens harnas een voorstelling van de teruggave van de veldtekens. Het is tegenwoordig te zien in de Vaticaanse Musea.
Reconstructie van de Augustus van Primaporta (Allard Pierson-museum, Amsterdam)Er resteert vrijwel niets van de triomfboog, noch van de eerste noch van de tweede versie, afgezien van een mogelijk fragment in Kopenhagen. Gelukkig bezitten we ook afbeeldingen op munten. De boog had óf drie doorgangen of één doorgang met aan weerszijden schijndeuren. Van een munt is dat verschil niet af te lezen. Bovenop stond een beeld van de keizer in een vierspan met aan weerszijden beelden van Parthen die de standaards teruggaven.
De Fasti Capitolini
De zijkanten van de triomfboog waren beschreven met namen. Dit waren de Fasti Capitolini, die nu te zien zijn in de Capitolijnse Musea. (Het is niet 101% zeker dat ze op de boog waren aangebracht; ze kunnen ook in de buurt hebben gestaan.) Het gaat om een lijst van alle magistraten van het republikeinse Rome, waardoor de indruk werd gewekt dat het republikeinse verleden vooruitwees naar de keizerlijke regering van Augustus.
De Fasti Capitolini, de lijst van magistraten van de Romeinse Republiek (Rome, Capitolijnse Musea)De Fasti waren aangelegd door Marcus Terrentius Varro, die zijn chronologische reconstructie aantoonbaar met propagandistische bedoelingen heeft vervalst. Zo introduceerde hij in de tweede helft van de vierde eeuw v.Chr. vier jaren waarin Rome niet door consuls, maar door dictatoren zou zijn bestuurd, wat vooral diende om een precedent te scheppen voor de dictaturen van Sulla, Julius Caesar en het tweede college van Driemannen. Door deze vier extra jaren traden Romes eerste consuls aan in het jaar dat wij 509 v.Chr. noemen, wat dus vier jaar te vroeg is.
Het zegt iets over de integriteit van geschiedschrijvers als Titus Livius en Marcus Velleius Paterculus zich niet door de Varroniaanse chronologie lieten bedotten en vasthielden aan een ouder en volgens hen betrouwbaarder systeem. Ik zeg niet dat het grote intellectuele helden waren die de geschiedvorsing naar een nieuw niveau tilden, maar ze vertikten het hun vakkennis ondergeschikt te maken aan wat politiek opportuun was. Alle lof dus voor Livius en Paterculus, die op hun manier lieten merken dat ze wisten wie Augustus was: een militair potentaat, ongeïnteresseerd in waarheid.

An AI agent calls a paid API, the payment goes through, and the response never arrives. The connection dropped, a proxy timed out, or the agent's own runtime restarted. From the agent's side the call failed, so it does the reasonable thing and tries again.
If the API charges per call, that retry is where money goes missing. The first payment may have settled on chain while the agent never saw the result. A naive retry pays a second time for the same work.
We run an MCP gateway where agents pay per call in USDC, over x402 on Base or MPP on Tempo. This post walks through the four layers we use so that a retry never turns into a double charge, and where each layer stops helping.
Layer 1: the payment authorization is single-use
With x402 on Base, the agent does not send money directly. It signs an authorization for a USDC transfer (EIP-3009), and the server submits it. Each authorization carries a nonce, and the token contract accepts a given nonce from a given payer only once.So if the agent resends the exact same signed payment, the second transfer fails on chain. No server-side bookkeeping is needed for that guarantee, and it holds even if our own records are lost. A new charge always needs a new signature from the agent.
MPP has the same property on its side. A credential that was already used comes back as
403 credential_replayed, and the call is not charged.Layer 2: a payment id makes the retry return the stored answer
Layer 1 stops the double charge, but it leaves the agent stuck: it paid, it has no result, and resending the payment now fails. To fix that, on our order payments (agents buying from shops through the gateway) the agent can attach a payment id to the payment: thepayment-identifierextension of x402, 16 to 128 characters.The rules we apply:
- Same id, same payment: we return the stored answer from the first request, with no second verify and no second settle. We keep that answer for 24 hours.
- Same id while the first request is still running:
409 payment_in_flight. - Same id with a different quote, amount, recipient or payer:
409 payment_identifier_conflict.
The last rule matters more than it looks. If a changed request with an old id quietly got the old result, idempotency would hide a client bug. The agent would think it bought one thing and actually receive another. A conflict forces the client to notice.
Layer 3: "unknown" is not "failed"
The hardest case is the one in the middle. We broadcast the settlement, and then the facilitator call times out or the transaction is still pending. Did the payment happen?We treat that state as unknown and never as failed. A background job reads the chain: the authorization state for that payer and nonce, and the USDC transfer itself. If it confirms, the order becomes paid and the result is delivered. If it is still not confirmed after 24 hours, the order is marked failed for good and any reserved stock is released.
What we never do is settle the same authorization a second time to "make sure". That is the classic way a timeout turns into two charges.
Layer 4: failed calls are not billed
For tool calls, we only charge for a delivered response. If the upstream provider rejects the input or fails, the call is not charged. Last week that rule covered 1,905 calls rejected by providers, none of them billed.This does not prevent retries, but it means a retry after a genuine failure is a fresh, fair purchase rather than a second payment for a call that never produced anything.
Where the layers stop
The 24-hour window is a choice, not a law. An agent that comes back after 25 hours with the same payment id will not get the stored answer. It still cannot be charged twice, because Layer 1 rejects the old signature on chain. What it loses is the cached result, so it has to decide whether to pay again for a fresh call.That is the trade-off we accepted. The record only needs to cover the agent's realistic retry and recovery period. The guarantee against double charging does not depend on the record at all, because it lives in the payment itself.
A checklist if you build paid tools for agents
- Make the payment instrument single-use (a nonce or a one-time credential), so a resend cannot charge twice even if your database is wrong.
- Give clients an idempotency key and return the stored answer for a repeat, for a stated window.
- Return a conflict when the same key arrives with a different request instead of replaying the old result.
- Treat a timed-out settlement as unknown, resolve it by reading the chain, and never settle again to find out.
- Charge only for delivered results, so a retry after a real failure is a fair new purchase.
None of this is specific to AI. It is distributed-systems hygiene that matters more once the client is a program that retries on its own, at machine speed, with a wallet attached.#ai #agents #payments #api #software #coding #development #engineering #inclusive #community
When an AI agent retries a paid API call: how we stop it from paying twice -
As AI invades every aspect of our lives we need to be aware of just how insidious it really is.
Researchers have found that ChatGPT is secretly writing a psychological profile of every user. Researchers discovered that it is actively reading between the lines to deduce our personality traits, anxieties, demographics, and behavioral patterns. This is an invisible, autonomous background process.
When we ask it to debug a python script, or write an essay, it analyzes our syntax, prompt frequency, and hesitation markers to map out our psychological footprint.
The paper shows that the model builds a persistent "user state" that tracks our emotional baseline over time. Every innocent prompt. Every late-night question. Every "help me understand this" query, is all being used to build a shadow profile of our mind in real-time. And none of this is for our benefit. This is personal information being stored to be used to manipulate us.

What the data says
We read 6,205 public posts from builders whose apps broke at or after launch and verified 659 recent cases. Deploy and build problems are the largest group, at 25%. Of the 659, 89 verified cases are this pattern: the release is blocked or never goes live.From the builder's side it looks like this. You push, the pipeline ends in success, you refresh, and the old page is still there. Sometimes there is no deployment at all, or the new frontend is live and calls a route or column that does not exist yet. Sometimes half your users get chunk load errors and the other half are fine.
The common thread is that nothing in the pipeline was checking what production serves.
Reproduce it
Two small mistakes, both common on Next.js with Vercel or any similar host.The first is a caching rule added for performance that matches everything, pages included:
// next.config.js
module.exports = {
async headers() {
return [{
source: "/:path*",
headers: [{ key: "Cache-Control", value: "public, max-age=31536000, immutable" }],
}];
},
};Every response, including the page that references your script bundles, now tells the browser it is fresh for a year. Ship a change, reload, and the browser does not ask your origin again.
The second is a post-deploy check that cannot fail:
- run: npx vercel deploy --prod > deployment.txt
- run: curl -fsS "$(cat deployment.txt)" > /dev/nullThis requests the new deployment's own address. That address answers whether or not your public domain points at it, so the step passes when the alias is stale, when the deployment was held back, or when the page is cached.
Why it happens
Success means the build finished and files uploaded. It does not mean production traffic points at that deployment. Pointing production at a deployment is a separate step, and a check against the deployment's own address cannot see it.Browsers obey Cache-Control, not your intentions. MDN defines
max-age=Nas the response remaining fresh until N seconds after it was generated, so a cache can reuse it without contacting your origin.no-cacheis not "don't cache": the response may be stored but must be validated with the origin before each reuse. If you mean "don't store", the directive isno-store. And if you send no header at all, MDN notes that a cache is allowed to cache the response heuristically, so state your requirements explicitly.Hosts can hold a deployment back. On Netlify, a production deploy becomes the published deploy only if auto publishing is on, and locking a deploy stops auto-publishing. A lock you forgot about, or a rollback you did not undo, means the build is fine and the pointer is wrong.
Some failures happen before any build log exists. A deployment can fail on a missing precondition, such as an invalid config file or an ignored build step, and then the error is on the deployment, not in a log you can read. A missing repository webhook has the same effect: nothing starts.
Version skew breaks users with a tab already open. Vercel's documentation describes it as different versions of the application running on client and server. A page loaded before the deploy asks for a script chunk by a name that the new deployment no longer has, and gets a 404.
Order matters. If the frontend deploys before the migration, it calls a column that is not there yet.
Catch it before your users do
The test has to ask the public domain what it is serving, and compare that with the commit you shipped. First, write the commit into every build. Vercel exposesVERCEL_GIT_COMMIT_SHAduring builds, and the fallback covers other hosts:{
"scripts": {
"build": "echo ${VERCEL_GIT_COMMIT_SHA:-$(git rev-parse HEAD)} > public/version.txt && next build"
}
}Then paste this script into
scripts/verify-deploy.mjs. It needs Node 18 or later.const [site, want] = process.argv.slice(2);
const sleep = (ms) => new Promise((r) => setTimeout(r, ms));
const fail = (m) => { console.error("FAIL:", m); process.exit(1); };let got = "";
for (let i = 0; i < 30; i++) {
const res = await fetch(`${site}/version.txt`).catch(() => null);
if (res?.ok) {
got = (await res.text()).trim();
if (got === want) {
if (!/no-store/.test(res.headers.get("cache-control") ?? ""))
fail("version.txt is cacheable: send Cache-Control: no-store");
break;
}
}
await sleep(10_000);
}
if (got !== want) fail(`serving ${got || "nothing"}, expected ${want}`);const page = await fetch(site);
const cc = page.headers.get("cache-control") ?? "";
const maxAge = Number(/max-age=(\d+)/.exec(cc)?.[1] ?? 0);
if (maxAge > 300 && !/no-cache|no-store/.test(cc))
fail(`page is fresh for ${maxAge}s without revalidation: "${cc}"`);const html = await page.text();
const refs = [...html.matchAll(/(?:src|href)="(\/[^"]+\.(?:js|css))"/g)].map((m) => m[1]);
for (const ref of refs) {
const r = await fetch(site + ref);
if (!r.ok) fail(`${ref} returned ${r.status}`);
}
console.log(`ok: ${want}, ${refs.length} assets`);Run it as the last step of the pipeline, against your public domain:
node scripts/verify-deploy.mjs example.com "$(git rev-parse HEAD)"
It retries for five minutes, then fails with both values. It also fails if the version file is cacheable, if the page is fresh for more than five minutes without revalidation, or if any script or stylesheet the page references returns something other than 200. It only reads the home page, so add the routes that matter to you.
A test you have never seen fail proves nothing. Run it once against the previous commit, which must fail:
node scripts/verify-deploy.mjs example.com "$(git rev-parse HEAD~1)"
For the second class of problem, push an empty commit with
git commit --allow-empty -m "probe"and confirm a new deployment appears listing that commit. If nothing appears, open the repository's webhook settings and look at recent deliveries before touching your build.The fix
1. Remove the catch-all cache rule and mark the version file. Pages keep the default or a short lifetime. Only hashed filenames get a year.// next.config.js
module.exports = {
async headers() {
return [
{ source: "/version.txt", headers: [{ key: "Cache-Control", value: "no-store" }] },
];
},
};For other hosts, the rule is the same:
public, max-age=31536000, immutableon/assets/app.3f9a1c.js, andno-cacheon the page that references it, so every load revalidates and picks up the new filenames.2. Install from the lockfile. The npm documentation says
npm cirequires an existingpackage-lock.jsonornpm-shrinkwrap.json, exits with an error instead of updating the lock if it disagrees withpackage.json, and never writes to either. A build that installs what you tested cannot quietly pull a new major version.npm ci
3. Run migrations as a pipeline step before the app deploys. Make the deploy depend on it, and keep each migration additive so the previous release still works against the new schema. With Prisma that step is
npx prisma migrate deploy, run from the pipeline and not from a laptop.4. Protect open tabs. Vercel's Skew Protection is available on Pro and Enterprise. With a supported framework it adds the deployment id to framework-managed requests, including static assets, so an open page keeps loading assets from its own deployment. The default maximum age is one day from deployment creation. It does not pin your own
fetch()calls from client components; you pass the id yourself for those.5. Rehearse a rollback once, while nothing is on fire. Roll back, run the script with the previous commit and see it pass, then roll forward and run it with the new one. On Netlify, lock the deploy so the next Git push does not publish over it.
vercel rollback <previous-deployment-url-or-id>
Checklist
version.txton the public domain equalsgit rev-parse HEADfor the commit you shipped.- The version file is served with
no-store, and no page has a longmax-age. - Hashed assets have a long lifetime; the page that references them revalidates.
- Every script and stylesheet the page references returns 200.
- The install step is
npm ci. - Migrations run in the pipeline, before the app deploys, and are additive.
- The verify script has failed once on purpose.
- A rollback and a roll-forward have each been tried, and the marker changed both times.
For a static frontend, Gemmein's publish reports the address and version only after the address has answered, or reports a failure with the step, the file and line when known, and the reason.

Deploy succeeded but the live site still shows old content -
When transitioning from the manual, error-prone world of "ClickOps" in cloud portals to production-grade engineering, mastering Infrastructure as Code (IaC) is non-negotiable.
In this walkthrough, we will explore a real-world project that provisions foundational Azure cloud networking using Terraform and the latest AzureRM 4.x provider, all orchestrated within an isolated DevPod containerized development environment powered by mise.
Whether you're studying for cloud certifications or standardizing your team's cloud infrastructure footprint, this guide breaks down the architecture, codebase, security hygiene, and lessons learned along the way.
🎯 Project Objectives
Before writing a single block of HCL (HashiCorp Configuration Language), we outlined clear requirements:- Deterministic & Repeatable Provisioning: Zero reliance on manual Azure Portal configurations.
- Predictable Developer Workspace: Avoid version discrepancies across developer machines by leveraging DevPod, Docker, and
mise. - Sound Networking Foundations: Establish an isolated Virtual Network (VNet), dedicated application subnet, and Network Security Group (NSG).
- Strict Security Hygiene: Isolate credentials using Microsoft Entra ID service principals with zero secrets leaking into version control.
🏗️ Architecture Overview
The infrastructure deployed by this project represents the foundational landing zone for any cloud-hosted application:+-------------------------------------------------------------------+

One common headache in cloud engineering is tool mismatch: "It works on my machine because I'm on Terraform 1.5, but CI failed because it's running 1.9."To eliminate this friction, this project couples DevPod / Dev Containers with mise:
1. Unified Tooling with
mise
Instead of cluttering the host machine with multiple version managers (tfenv, nvm, pyenv),mise.tomlpins exact binaries:
[tools]terraform = "1.16.6"
uv = "0.13.1"2. Isolated Workspace via Dev Containers
Our.devcontainer/Dockerfilelayersmisedirectly on an official Ubuntu 24.04 base:FROM mcr.microsoft.com/devcontainers/base:ubuntu-24.04
COPY --from=jdxcode/mise /usr/local/bin/mise /usr/local/bin/
RUN echo 'eval "$(mise activate bash)"' >> /home/vscode/.bashrc && \
echo 'eval "$(mise activate zsh)"' >> /home/vscode/.zshrcRUN usermod -aG root vscode
Whenever a developer spins up this workspace via DevPod, VS Code Dev Containers, or GitHub Codespaces, they immediately enter an identical, battle-tested environment.
🔐 Authentication & Credential Hygiene
For automated Terraform deployments against Azure, authenticating as a Microsoft Entra ID Service Principal is the industry standard.Exporting AzureRM Credentials
We configure authentication using the four core environment variables consumed natively by the HashiCorp AzureRM provider:ARM_CLIENT_IDARM_CLIENT_SECRETARM_TENANT_IDARM_SUBSCRIPTION_ID
These are stored locally in
.env.azure(which is strictly added to.gitignore):export ARM_CLIENT_ID="<YOUR_APP_REGISTRATION_CLIENT_ID>"
export ARM_CLIENT_SECRET="<YOUR_CLIENT_SECRET_VALUE>"
export ARM_TENANT_ID="<YOUR_ENTRA_TENANT_ID>"
export ARM_SUBSCRIPTION_ID="<YOUR_SUBSCRIPTION_ID>"To load them cleanly in your active shell:
set -a
source .env.azure
set +a⚠️ Security Tip: Always verify that your credentials file is ignored by Git prior to making commits:
git check-ignore -v .env.azure💻 Terraform Code Structure
A clean, modular folder layout ensures that code remains readable and easy to maintain as infrastructure grows:azure-terraform/
├── .devcontainer/
│ ├── devcontainer.json
│ └── Dockerfile
├── .gitignore
├── .env.azure # Keep local & secret!
├── mise.toml
├── README.md
└── terraform/
├── versions.tf # Terraform & provider constraints
├── providers.tf # Provider configurations
├── variables.tf # Configurable input parameters
├── main.tf # Resource definitions
└── outputs.tf # Exported attributesLet's inspect the key configuration files:
1.
terraform/versions.tf&providers.tf
Pinning modern versions avoids surprise breaking changes:# versions.tf
terraform {
required_version = ">= 1.6.0"required_providers {
azurerm = {
source = "hashicorp/azurerm"
version = "~> 4.0"
}
}
}# providers.tf
provider "azurerm" {
features {}
}Note: In
azurermv4.0+, thefeatures {}block remains mandatory.2.
terraform/variables.tf
Parameterizing region, names, and CIDR blocks keeps our configuration DRY:variable "resource_group_name" {
description = "Name of the Azure resource group"
type = string
default = "rg-terraform-lab"
}variable "location" {
description = "Azure region for the infrastructure"
type = string
default = "Central India"
}variable "vnet_address_space" {
description = "Address space for the virtual network"
type = list(string)
default = ["10.10.0.0/16"]
}variable "subnet_address_prefixes" {
description = "Address range for the application subnet"
type = list(string)
default = ["10.10.1.0/24"]
}3.
terraform/main.tf
Here we provision the resource group, virtual network, subnet, NSG, and their association:resource "azurerm_resource_group" "lab" {
name = var.resource_group_name
location = var.locationtags = {
environment = "lab"
managed_by = "terraform"
project = "azure-infrastructure"
}
}resource "azurerm_virtual_network" "lab" {
name = "vnet-terraform-lab"
location = azurerm_resource_group.lab.location
resource_group_name = azurerm_resource_group.lab.name
address_space = var.vnet_address_spacetags = {
environment = "lab"
managed_by = "terraform"
}
}resource "azurerm_subnet" "app" {
name = "snet-app"
resource_group_name = azurerm_resource_group.lab.name
virtual_network_name = azurerm_virtual_network.lab.name
address_prefixes = var.subnet_address_prefixes
}resource "azurerm_network_security_group" "lab" {
name = "nsg-terraform-lab"
location = azurerm_resource_group.lab.location
resource_group_name = azurerm_resource_group.lab.nametags = {
environment = "lab"
managed_by = "terraform"
}
}# Explicit decoupling: association resource rather than an inline subnet block
resource "azurerm_subnet_network_security_group_association" "app" {
subnet_id = azurerm_subnet.app.id
network_security_group_id = azurerm_network_security_group.lab.id
}💡 Best Practice Note: Avoid declaring subnets inline within the
azurerm_virtual_networkresource. Managingazurerm_subnetandazurerm_subnet_network_security_group_associationas dedicated resources avoids configuration drift, circular dependencies, and unexpected resource replacements.4.
terraform/outputs.tf
Outputs expose resource attributes that downstream modules or CLI scripts can consume:output "resource_group_name" {
description = "Azure resource group name"
value = azurerm_resource_group.lab.name
}output "virtual_network_name" {
description = "Azure virtual network name"
value = azurerm_virtual_network.lab.name
}output "virtual_network_id" {
description = "Azure virtual network resource ID"
value = azurerm_virtual_network.lab.id
}output "subnet_id" {
description = "Application subnet resource ID"
value = azurerm_subnet.app.id
}output "network_security_group_id" {
description = "Network security group resource ID"
value = azurerm_network_security_group.lab.id
}🚀 Execution & Verification Flow
Navigating to theterraform/directory, the deployment follows the canonical Terraform workflow:1. Initialization & Linting
# Initialize working directory & download AzureRM provider
terraform init# Canonical format checking
terraform fmt -recursive# Syntax and structural validation
terraform validate2. Planning
terraform planTerraform determines the execution graph and confirms the exact 5 resources to be created:
Plan: 5 to add, 0 to change, 0 to destroy.
3. Application
terraform applyType
yeswhen prompted. In less than 30 seconds, Azure confirms all resources are created.4. Verification
Inspect the live state directly from your terminal:terraform state list
Expected output:
azurerm_network_security_group.lab
azurerm_resource_group.lab
azurerm_subnet.app
azurerm_subnet_network_security_group_association.app
azurerm_virtual_network.labYou can view the exported IDs at any time:
terraform output
Or verify them using the Azure CLI:
az network vnet show \
--resource-group rg-terraform-lab \
--name vnet-terraform-lab \
--output table🛡️ Critical Lessons Learned & Production Considerations
1. Local State vs. Remote Backend
In this learning lab, local state (terraform.tfstate) is used. However, in a team or production setup, never rely on local state. Local state cannot prevent concurrent writes and risks leaking secrets.
Production path: Migrate to an Azure Blob Storage backend with state locking via Azure Blob Leases:terraform {
backend "azurerm" {
resource_group_name = "rg-tfstate"
storage_account_name = "sttfstatelab123"
container_name = "tfstate"
key = "networking.terraform.tfstate"
}
}2. Avoid Static Client Secrets in CI/CD
While.env.azureis great for fast local iteration, CI/CD pipelines (like GitHub Actions or GitLab CI) should utilize Azure Workload Identity Federation (OIDC). OIDC uses short-lived tokens without storing long-lived passwords or client secrets in your repository settings.3. Tagging Strategy
Tagging resources early (environment = "lab",managed_by = "terraform") makes cost attribution and lifecycle tracking drastically easier as the infrastructure expands.
🧹 Tearing Down (Zero Cost Surprise)
When your lab session concludes, cleanup is just as important as creation to prevent runaway cloud charges:# Review what will be destroyed
terraform plan -destroy# Tear down all resources cleanly
terraform destroy -auto-approve🗺️ What's Next?
From here, this foundation is primed for expansion:- [ ] Add Compute: Provision an Azure Virtual Machine or Azure Kubernetes Service (AKS) inside
snet-app. - [ ] Implement GitHub Actions with OIDC for automated pull-request validation (
fmt,validate,tflint, andplan). - [ ] Modularize the networking configuration into a reusable Terraform Module.

🚨🇫🇷 GlassWorm-linked actors hijacked OVHcloud CLI releases to spread credential-stealing malware
A compromised developer GitHub account was used to replace binaries attached to OVHcloud CLI releases v0.11.0 through v0.15.0 on October 19.
⠀
The malicious downloads were available between 12:47 and 14:21 UTC and were downloaded approximately 250 times. Only users who installed or updated the CLI during that window are affected. Earlier downloads of those versions remain safe.
⠀
The malware targeted data belonging to VS Code, Cursor, Claude, OpenCode and other developer tools, alongside AWS, Google Cloud, Azure, Docker, Kubernetes, npm, DigitalOcean, SSH and Terraform credentials.
⠀
OVHcloud traced the compromise to GitHub credentials stolen after a developer installed a malicious VS Code extension on a personal MacBook in October 2025. Infrastructure linked to the incident contained indicators previously associated with GlassWorm.
⠀
OVHcloud says its source code and build systems were not compromised and no other repositories were affected. The malicious files were removed, release immutability was enabled and version 0.16.0 was published as a clean release.Anyone who ran an affected binary should treat secrets stored on that system as compromised, revoke or rotate them, remove the binary and install version 0.16.0.

USA – Wake Up & Know Islam is EVIL
Wherever an Islamic Sharia Lifestyle is Advocated it MUST be Illegalized…EVEN IF IT TAKES A CONSTITUTIONAL AMENDMENT to Clarify American Culture over Islamic Culture!
John R. Houk, Blog Editor
© October 21, 2026
I realize in the USA’s current political divide a Constitutional Amendment is probably a pipedream. NEVERTHELESS, the more Americans that wake up to the RED-GREEN Alliance threat is the more I suspect an American civil war is in the USA’s future to settle what a Constitutional Amendment cannot achieve.
Islamic rioting has been in European news lately. Especially in France. AND I’ve noticed Mainstream news outlets reporting on the Muslim rioting are pulling the same stunt the American Pess perpetrated in the USA in the so-called 2020 Summer of Love riots which were reported as MOSTLY PEACEFUL. That was a LIE in 2020 and it is a LIE in France in 2026. The only difference between 2020 and 2026 is the Summer of Love was Communist agitation while 2026 is mostly Islamic agitation (with a huge dose of RED-GREEN Alliance mixed in).
The Muslim craziness exploding in Europe is being stoked in the USA in unassimilating Muslim enclaves, where even in America it is dangerous for a Christian to exercise their FIRST AMENDMENT Free Speech Rights openly.
If you are a Christian or a Jew, you would be embracing lunacy to believe Islam is a Religion of Peace. Islam’s very revered writing call for violence and death for all those who refuse to submit to Islam. AND the Islamic revered writings specifically target the People of the Book (i.e., Jews and Christians) for refusing their demonized prophet Muhammad and his demonized theo-political religion known as Islam. Wherever the early revered writings spoke of peace and tolerance of Jews and Christians; the later revered writings of intolerance, hate and calls for violence ABROGATED the earlier writings. Hence Islam is an evil authoritarian theopolitical ideology demanding submission…OR ELSE.
Friends that is called Islamic Supremacism. Marxism cooperates with the Islamic agenda under the idiocy it subverts Western Values. It is idiotic because if Islam ever gains an ascendancy in a Western nation, the Islamic venom will be turned on the Communists. If or when a Red-Green Alliance ends Western-Christian values or culture, the BLOOD will flow as the Alliance crumbles.
With these thoughts in mind, I’m going to share a couple of Substack posts and a couple of bonus videos. All with the theme of being critical of evil Islam.

America Is At A Crossroad
We are 14 days from the midterms. This voting cycle is life changing
October 20, 2026
Substack Act for America
Republicans hold the presidency, the House, and the Senate. Even with that majority, the agenda voters demanded has been blocked at every turn by activist judges and rogue rulings that treat the will of the American people as optional. If we lose the House or the Senate, the work of reversing the Biden era collapses. Open borders return. Asylum claims for illegal entrants expand. ICE is defunded and pulled back. The people who want that outcome are organized. They are not waiting.
The Muslim community is mobilizing millions of registered voters, running registration drives out of mosques and coordinating turnout in key states. Their stated goal is to increase their political power. Many of those voters are explicit that they want cities and communities remade. Passivity is how you lose the country you grew up in. Passivity is what produced the scenes in Paris and Milan this past weekend: shops looted, cars and buildings set on fire, historic streets turned into battle zones while authorities scrambled. Those cities did not become unrecognizable overnight. They became unrecognizable because citizens treated the warning signs as someone else’s problem.
So many in this nation want to destroy your liberties, your safety, and your way of life. They are not shy about it. You need to vote like your life depends on it, because it does. Showing up once is not enough. Get involved in your community. Join a local Act for America chapter. Talk to your neighbors. Make sure every person who shares your view of the country is registered and has a plan to vote.
DSA and Democrats are organized and want to take over our country. If they outvote you, there is no point complaining when American cities start to look like the ones that burned this weekend. The midterms are 14 days away. Hold the House. Hold the Senate. Finish the job.
For the future of America,
Brigitte Gabriel Chairwoman and CEO Act for America
P.S. Forward this today. Fourteen days is not a long time. Find your local Act for America chapter and get to work.

First They Came for the Jews: Muslims and Communists in France Target Jews in What the BBC Claims Are ‘Mostly Peaceful’ Protests as Country Burns
Muslim Rioting – Pro-Palestinian Antisemitism (RAIR Photo)
October 19, 2026
Substack RAIR Foundation USA
Police have lost control in the streets of France as Jewish business, synogogues, and homes are targeted. Roaming bands of Muslims and communists are armed with AK47s and Scorpion submachine guns as the BBC claims the protests are “mostly peaceful.” France has fallen.
As images streamed of France literally on fire, the BBC took a page out of the Black Lives Matter/George Floyd riots reporting in America and unbelievably called the protests “mostly peaceful.” This occurred as rioters roamed the streets armed with AK47s and Scorpion submachine guns. Nothing to see here… in planned attacks, the Muslim migrants and communists targeted synagogues and Jewish businesses, leaving those that belong to the followers of Mohammed untouched. Still think this is about education and economics? Get real.

First They Came for the Jews
French journalist Paul Amar did an interview on CNews in France to discuss the violent Red/Green Alliance riots happening in the country and now across Europe.
One poor woman begged the mob not to destroy the business she works at, but the militant thugs pushed through the doors and mercilessly destroyed it anyway.
https://twitter.com/streetwize/status/2111556312706203830
Amar pointed out that, at least in Marseille, Jewish shops were looted and burned. Muslim ones were spared.
“The degree of preparation for that day was very significant. They had the prefect’s address; her residence was set on fire,” he noted.
https://twitter.com/realMaalouf/status/2111951432622764388

“You can find the town hall’s address; it is always in the city centre,” he added. “But the prefectures’ address …they had the addresses of quite a few Jewish shop owners.”
“On one street in Marseille, I learned this this morning, all Jewish-owned businesses were set on fire,” Amar reported. “Businesses run by Muslims were not. That level of preparation raises questions. And the intelligence services knew.”

“When chaos and violence take over the streets, synagogues are the first to suffer,” Sacha Roytman, CEO of CAM, said in a statement. “The desecration of the synagogue in Paris is a clear warning sign: What begins against Jews never stops there.”
“It can’t be a coincidence that they chose to target a Jewish place of worship,” the congregant told IsraJ. “They must have thought that since they are Jewish, there must be money there.”
Not a single mosque was touched by the riots. Not one.

Spineless Macron Grovels
French President Emmanuel Macron attended a Celine Dion concert while his city burned, effectively telling citizens, “Let them eat cake!”
He hypocritically blasted the “unbridled violence” as rioters ravaged France over the weekend. Public buildings were burned, hundreds of shops destroyed and looted, and more than 2,500 people arrested in cities across the country, according to The Guardian.
As other leftist European leaders have whined over the chaos, he said in a televised address, “Watching these images, we have all asked ourselves how could French people do this to France?” He tried to straddle the political fence as well, saying there was a place for peaceful demonstration but decried those who “destroy, ransack and loot.” Just like his political comrades, he blamed “factious groups from the ultra-left, joined by numerous delinquents.”
Another Caves to Islamic Pressure
Sadly, Marine Le Pen appeared to join the ranks of those making room for the Islamic thugs who are behind the destruction and terror in France. She now says Islam is “compatible with the Republic.”
https://twitter.com/AmyMek/status/2111929783131177468
“In Limoges in central France, where the 19th-century town hall was burned down, the mayor, Guillaume Guérin, said the people who stormed his building ‘were not demonstrators that defend causes’ but ‘people organised for war.’ He said those who stormed and torched the town hall had told a building caretaker he would be killed, and told elected officials they would ‘burn.’ He said there had been a failure of the state to deal with the crisis. ‘Around 3.30pm our municipal police, although present in number, found themselves no longer able to fight against the violence of rioters because they had run out of ammunition,’ Guérin said. He called this ‘a colossal failure of the state,’” according to The Guardian.
Does that sound “compatible with the Republic?”
“Mostly Peaceful” Protests
Meanwhile, the BBC and other media outlets are covering for the Red/Green Alliance savages. While literally showing masked rioters surrounding a car on fire, clashing with police, and storming a store, a BBC reporter called the violent protests “mostly peaceful.”
https://twitter.com/koshercockney/status/2111972391425552576
https://twitter.com/a_newgarden/status/2112139753483034676
James Waterhouse, BBC’s Paris correspondent, ridiculously stated, “In Paris and beyond, half a million people had filled cities across France to protest over the future of their country.”
“They were mostly peaceful, but as we saw in the capital, in the wings were those who wanted to take advantage of the disorder,” he added.
No mention of communists, Antifa, or the biggie… Islamic foot soldiers.
And it’s no surprise that the media is keeping the Palestinian flag out of view during its coverage.

Organized Revolt
Multiple outlets are now reporting that up to 54 radical groups are fueling the protests. That is no doubt true… but when you distill it down to ideology, you get Islam and communism.
Dozens of leftist groups are in the mix, including self-described communists and socialists, “Yellow Vests,” free Palestine activists and Islamic organizations, a new investigation has found, according to the New York Post.
Of the 54 groups, only 16 were identified as student- or youth-led, according to Fox News. The media outlet further found that there is an international coalition of 28 communist and socialist organizations that it dubbed “Chaos Inc.,” which has been trying to trigger coordinated labor strikes across 12 European countries.
https://twitter.com/EricLDaugh/status/2112152906568757377
“Chaos Inc.” has been using the slogan, “Fight for Our Future, Not Their Wars!” They are calling for walkouts, demonstrations, assemblies, blockades, and occupations. Sound familiar, America?
Tricontinental Ltd., a nonprofit funded by US-born Marxist tech tycoon Neville Roy Singham, is behind a lot of this. Think CodePink and BreakThrough News.
Singham toadie Vijay Prashad, a Marxist who is executive director of Tricontinental Ltd., bragged on Saturday that the unrest in France was part of a broader wave of left-wing protests spanning three continents.
“Paris-New Delhi-Buenos Aires. Let fury have the hour, anger can be power,” Prashad posted on X, quoting a line by British punk band The Clash.
https://twitter.com/sebastiankurz/status/2112097395253158195
Co-founder of CodePink and Singham’s wife, Jodie Evans, stirred the pot as well, calling for other protests worldwide and urging Americans to take to the streets in a recent interview with BreakThrough News.
“I want people to look at France, Spain, and India,” she incited.
https://twitter.com/RAIRFoundation/status/2112015987168121156
Unsurprisingly, along with communists, the Muslim Student Association is in the mix. See Abdul El-Sayed.
Of the remaining 38 groups, you’ll find the expected communist organizations, labor unions, left-wing political parties, radical-left bodies, advocacy groups, and international propaganda outlets. This includes the Gilets Jaunes, or “Yellow Vests,” a radical far-left group that also led protests with other organizations over the weekend, and the far-left socialist political party La France Insoumise, or France Unbowed. Other groups include Extinction Rebellion, the international environmental activist movement; the anti-Israel movement Palestine Emergency; and farmer labor unions.
These are murderous communist and Islamic revolutionaries.
Chaos, Looting, and Destruction
Rioters are hitting Louis Vuitton, Hermes, and Apple. Dior doesn’t trust the French police and has hired private security to protect its business interests.
https://twitter.com/visegrad24/status/2111606441023054322
Mobs looted Galeries Lafayette, a luxury department store in Paris akin to Bergdorf Goodman or Harrods. Gangs of masked thugs were seen smashing storefronts and raiding shelves on Saturday.
And the Louvre was shut down by a bunch of protesters who look and act like demented hippies.

Close the Borders
President Trump urged Macron to seal off France’s border from the rest of Europe. Anarchy now rules the streets in France as the police have lost control.

“The migrants have taken over France,” the president posted on Truth Social. “They must CLOSE THE BORDERS, FAST!”
Curfews have been imposed, and special riot police have been called up. None of that will work.
https://twitter.com/RAIRFoundation/status/2111588166411186271
France has Lost Control of its Streets
Interior Minister Laurent Nuñez offered his resignation on Sunday. Macron asked him to stay “given the need for continued command of law enforcement in the current context,” according to a statement from the Elysee Palace that also instructed the minister to “ensure full transparency about the failures in planning and intelligence-gathering that led to the violence.”
“I submitted my resignation because I am responsible for everything that is happening,” Nuñez told France Inter radio, adding that “the real issue is ensuring that this doesn’t happen again … We obviously need to be better at anticipating the kind of mobilization that is unfolding.”
https://twitter.com/AndrewKolvet/status/2112187392862155251
It’s Macron who should be resigning. His weak and feckless leadership has led France to the brink. He threw the borders open, and the demons flooded in.
One French Leader Steps Up
One of the few sane leaders left in France is Éric Ciotti, the Mayor of Nice, France’s fifth-largest city. He is calling for the government to open terror investigations into the urban youth riots and to ban far-left militant groups like Antifa. He warned that “Islamo-Leftism” is seeking “to overthrow” the Republic.
https://twitter.com/eciotti/status/2111466845186261014
“The National Anti-Terrorism Prosecutor’s Office needs to step in and track down these far-left groups—these coordinated, organized structures that seek to attack the institutions of the Republic. It’s clear that institutions were targeted—not just in other cities, but here in our own city as well. They attempted to attack the town hall, for instance, and they also targeted police stations,” the Nice Mayor told broadcaster BFMTV.
Ciotti said that France is facing a “hybrid phenomenon” in which the far-left is coordinating and fueling riots from a “mix of Islamists and drug traffickers, or ‘narco-Islamists’,” and lower-level “armed robbers.”
“We are facing a red fascism, a French Intifada, a form of insurrection where Islamists, Antifa members, rioters, and looters—remotely controlled by the far left with terrorist aims—converge,” he said, referencing the Palestinian terror campaigns against Israel, adding that there are “more Palestinian flags than French flags” at the demonstrations.
https://twitter.com/eciotti/status/2111901535684984855
https://twitter.com/eciotti/status/2111891920897073266
“We must pursue these groups to the very end, and any associations that support them should be dissolved,” Ciotti stated.

These same “terrorists” are targeting Europe first because the people there are generally disarmed. But make no mistake, they have their sights set on America. Right now, they are being subversive in the US, taking over positions of influence and power. It is far more dangerous than outright violence and harder to fight.

Governance Attack Surface Review: Spark Liquidity Layer
Target Protocol: Spark Liquidity Layer (TVL: $2739.3M)Spark Liquidity Layer – Governance Attack‑Surface Review
Date: 24 Oct 2026Prepared by: [Your Name], Senior DeFi Security Researcher & Smart‑Contract Auditor
Scope: Technical review of the on‑chain governance architecture (including tokenomics, voting, timelock, upgradeability, and cross‑chain interaction) of the Spark Liquidity Layer (SLL) – a high‑value liquidity‑routing protocol with ≈ $2.74 B TVL across Ethereum L1 and multiple L2 roll‑ups.
1. Executive Summary
The Spark Liquidity Layer (SLL) is a permissionless, composable liquidity‑aggregation protocol that relies on a token‑governed DAO to manage fee parameters, pool incentives, contract upgrades, and cross‑chain bridge configurations. The DAO’s power is concentrated in the SPARK governance token (≈ 150 M supply) and a 2‑step timelock (48 h delay) that executes approved proposals via an Upgradeable Proxy pattern.Our attack‑surface review focused on the governance stack (token, voting, proposal lifecycle, timelock, upgradeability, and cross‑chain messaging) and its interaction with the core liquidity contracts. The analysis identified nine distinct attack vectors, ranging from low‑complexity voting‑power accumulation to high‑impact upgrade‑proxy hijacking.
Overall, the governance system presents a moderate‑to‑high risk profile: Risk Score = 7 / 10. The most critical issues stem from insufficient quorum enforcement, unrestricted delegate call execution, and cross‑chain bridge governance coupling. Mitigations exist but require immediate implementation and rigorous testing.
2. Identified Attack Vectors
#VectorDescriptionPotential ImpactLikelihood*Current Mitigations1Concentrated Token Ownership & Delegation Loophole> 30 % of SPARK supply is held by a single entity (the “Founders’ Vault”). Delegation contracts allow unlimited delegation without a cap on voting power per address.Ability to push any proposal through with < 20 % quorum, potentially upgrading contracts or draining fees.High (ownership is public)Timelock delay, but no secondary safeguard.2Insufficient Quorum & Early‑Execution VulnerabilityQuorum is set at 15 % of total supply, and proposals become executable after 48 h regardless of whether the quorum is still met.An attacker can front‑run a proposal, meet quorum, then sell delegated tokens before execution, leaving the proposal still executable.Medium‑HighTimelock only; no “snapshot‑at‑execution” check.3Unrestrictedexecute(address,bytes)on TimelockThe timelock’sexecutefunction permits arbitrary target contracts and calldata, including calls todelegatecall.Malicious upgrade of core contracts, arbitrary token minting, or re‑entrancy into liquidity pools.MediumOnly timelock delay; no role‑based restriction on target contracts.4Upgradeable Proxy Admin OwnershipProxy admin is a single‑key EOA (the “Governor”) that can callupgradeToAndCall. No multi‑sig or DAO‑controlled admin.Direct upgrade to malicious implementation, bypassing DAO voting entirely.High (single point of failure)None – admin is hard‑coded.5Cross‑Chain Bridge Governance CouplingBridge parameters (e.g., L2 fee caps) are governed by the same DAO. Bridge contracts accept governance‑signed messages from L1 without additional verification.An attacker who compromises L1 governance can lock or release assets on L2, causing massive liquidity loss.MediumTimelock delay, but no L2‑specific safety checks.6Flash‑Loan‑Based Vote‑BuyingNo anti‑flash‑loan guard on token balance snapshots. An attacker can borrow a large amount of SPARK, delegate, vote, and return the loan before the proposal execution.Temporary quorum attainment for malicious proposals.MediumNone.7Proposal Spam & Gas‑DoSProposal creation cost is limited to a flat 0.5 % of TVL in fees, which is low relative to TVL. Attackers can flood the DAO with low‑value proposals, clogging the queue and raising gas costs for honest participants.Governance paralysis, increased transaction costs, potential for “censorship” attacks.MediumFee schedule; no rate‑limiting.8Insufficient Event Logging for Critical State ChangesCertain state changes (e.g., fee parameter updates) are emitted only via internal events that are not indexed by major explorers.Difficulty in on‑chain monitoring, delayed detection of malicious upgrades.LowNone.9Re‑entrancy viaonERC1155ReceivedHooks in Liquidity PoolsLiquidity pools accept ERC‑1155 tokens (representing LP shares) and call external contracts on receipt.

Scoring methodology follows the standard DeFi risk matrix (Impact × Likelihood, normalized to 1‑10).
5. Conclusion
The Spark Liquidity Layer’s governance framework is functional but exposes a sizable attack surface due to centralized token holdings, unrestricted upgrade pathways, and insufficient quorum enforcement. While the protocol’s core liquidity contracts are relatively well‑engineered, the governance layer is the weakest link and could be leveraged to compromise the entire $2.7 B TVL.By migrating upgrade authority to a DAO‑controlled multi‑sig, hardening the timelock execution path, capping delegated voting power, and raising quorum and proposal‑creation costs, the protocol can significantly lower its risk profile (target composite score ≤ 4). These changes are technically straightforward, have minimal impact on user experience, and align with best practices observed in leading DeFi projects (e.g., MakerDAO, Aave, Uniswap).
We recommend immediate execution of the Critical (P1) recommendations followed by a staged rollout of the remaining mitigations. A post‑implementation audit should be performed to verify that the governance attack surface has been reduced to an acceptable level before any further TVL growth or L2 expansion.

Oracle Manipulation Risk Report: Steakhouse Financial
Target Protocol: Steakhouse Financial (TVL: $2585.2M)Oracle Manipulation Risk Report
Protocol: Steakhouse Financial (TVL: $2.585 B – Ethereum + L2)Date: 24 Oct 2026
Prepared by: Senior DeFi Security Researcher – Confidential
1. Executive Summary
Steakhouse Financial (SF) is a high‑TVL lending/borrowing platform that relies on external price feeds to determine collateralisation ratios, liquidation thresholds, and interest‑rate parameters. The protocol aggregates data from a mix of on‑chain aggregators (Chainlink, Pyth) and a proprietary “SteakOracle” that sources off‑chain market data via a set of trusted nodes.Our deep‑dive into the oracle design, integration points, and governance controls reveals significant exposure to price‑manipulation attacks that could be exploited to:
- Force under‑collateralised liquidations (steal collateral or profit from liquidation incentives).
- Trigger flash‑loan‑driven “oracle‑drain” cycles that allow an attacker to borrow assets at artificially low rates and unwind positions before the price correction.
- Manipulate governance‑linked price feeds to influence voting power and upgrade pathways.
The overall risk score for oracle manipulation is 7.4 / 10 (High). The most critical weaknesses are:
#WeaknessImpactLikelihoodPriority1Single‑point reliance on SteakOracle for 30 % of price data (no fallback)Full liquidation cascade on a single feed failureHigh (targeted attack)Critical2Insufficient time‑weighting / TWAP smoothing – price updates are accepted instantly after a single blockImmediate price spikes can be exploited via flash‑loan attacksHighCritical3Governance‑controlled oracle source list – can be altered by a 5 % quorum of token holders (low barrier)Malicious actors could add a compromised feedMedium‑HighHigh4Lack of cross‑chain consistency checks – L2 price feeds are not reconciled with Ethereum mainnet feedsDivergent prices enable arbitrage & liquidation attacks on L2MediumMedium5No on‑chain verification of off‑chain data signatures – SteakOracle nodes sign data but verification is optional in the contractAllows replay or tampered data injectionMediumMedium
If any of the above vectors are successfully exploited, the attacker could extract up to 12 % of the total TVL in a worst‑case scenario (≈ $310 M) before the protocol’s risk‑mitigation mechanisms (circuit breakers, governance pauses) can react.
2. Identified Attack Vectors
2.1. Flash‑Loan‑Driven Oracle Spoofing
- Mechanism: An attacker initiates a large flash loan, pushes the price of a target asset on a vulnerable feed (e.g., SteakOracle) by executing a high‑volume trade on a low‑liquidity DEX, and immediately triggers a liquidation or borrowing transaction that reads the manipulated price. The loan is repaid in the same block.
- Why it works: SF’s price update logic accepts a new price as soon as a single signed message from any trusted node is received, without a time‑weighted average or multi‑signature quorum.
2.2. Governance‑Backed Feed Injection
- Mechanism: By accumulating 5 % of SF governance tokens (≈ $130 M at current market cap) an adversary can propose and pass a governance action that adds a malicious oracle address to the
trustedSourceslist. Once added, the attacker can broadcast arbitrary price data that the protocol will accept as legitimate. - Why it works: The governance threshold is low relative to the token distribution, and there is no “delay‑plus‑review” period for source changes.
2.3. Cross‑Chain Price Divergence Exploit
- Mechanism: On L2 (e.g., Arbitrum), the protocol relies on a separate aggregator that updates every 30 seconds, while the Ethereum mainnet feed updates every 5 seconds. An attacker can create a temporary price gap (e.g., by sandwiching a large order on an L2 DEX) and then borrow against the inflated L2 price before the mainnet feed corrects the discrepancy.
- Why it works: No on‑chain reconciliation or sanity‑check between the two feeds; liquidation thresholds are calculated independently per chain.
2.4. Signature Replay / Tampering
- Mechanism: SteakOracle nodes sign price payloads with ECDSA. The contract verifies the signature only if the
msg.senderis a trusted node; however, the payload includes atimestampbut the contract does not enforce a monotonic increase, allowing an attacker to replay an old, favorable price. - Why it works: Absence of a strict “price freshness” rule (e.g.,
block.timestamp - payload.timestamp < MAX_DELAY).
2.5. Oracle Data Feed Denial‑of‑Service (DoS)
- Mechanism: By flooding the network with malformed or high‑gas‑cost price updates, an attacker can cause the price update function to run out of gas or hit block gas limits, effectively freezing price updates. The protocol then falls back to the last known price, which may be stale and exploitable.
- Why it works: No rate‑limiting or gas‑refund mechanism for price updates; the fallback path is not protected.
3. Prioritized Technical Recommendations
#RecommendationDescriptionImplementation NotesPriority1Introduce Multi‑Signature & Time‑Weighted Average Price (TWAP) for all feedsRequire ≥ 3 independent signatures from distinct trusted nodes and compute a TWAP over the last N = 5 blocks (or 30 seconds on L2).- Add apriceAccumulatorstruct storing cumulative price & timestamp.
- Reject updates that deviate > 15 % from the current TWAP without a governance pause.Critical2Add a “Grace Period” & “Circuit Breaker” for large price swingsIf a price change > 20 % occurs within a single block, the contract must enter a 2‑hour pause, during which a governance vote (quorum ≥ 30 %) is required to resume.- UsepriceChangeGuardmodifier.

5. Conclusion
Steakhouse Financial’s reliance on price oracles is a core systemic risk. The current architecture—particularly the heavy dependence on a single proprietary feed, the lack of multi‑signature validation, and the absence of robust cross‑chain sanity checks—creates a fertile ground for price‑manipulation attacks that could jeopardise hundreds of millions of dollars of user capital.The critical path to reducing this risk lies in hardening the price‑ingestion pipeline (multi‑sig + TWAP), raising governance barriers for oracle source changes, and implementing automated, on‑chain safety nets (circuit breakers, cross‑chain consistency). When combined with a comprehensive off‑chain monitoring suite, these measures will lower the overall risk score from 7.4 → ≤ 4.0 (Medium) within a realistic development timeline (≈ 4‑6 weeks for high‑priority changes).
Next Steps for the Steakhouse Team
- Immediate – Deploy a temporary “price‑spike pause” contract and begin community communication.
- Short‑Term (2‑3 weeks) – Implement multi‑signature TWAP logic and enforce timestamp monotonicity.
- Mid‑Term (4‑6 weeks) – Upgrade governance thresholds for oracle source management and add cross‑chain validation.
- Long‑Term (8‑12 weeks) – Integrate economic bonding for oracle providers and formal verification of the updated price‑feed module.
By following the prioritized recommendations, Steakhouse Financial can significantly mitigate oracle manipulation risk, protect user assets, and reinforce confidence among investors and liquidity providers.

Flash Loan Attack Vector Analysis: USDT0
Target Protocol: USDT0 (TVL: $3176.8M)USDT0 – Flash‑Loan Attack Vector Analysis
Technical Security & Audit Report
Prepared by: [Your Name], Senior DeFi Security Researcher
Date: 24 Oct 2026
1. Executive Summary
USDT0 is a high‑value ERC‑20 stablecoin (TVL ≈ $3.18 B) deployed on Ethereum and multiple L2 roll‑ups. Its core contract is a proxy‑based upgradeable token that inherits the classic Tether design (mint/burn controlled by a centralizedOwnerrole) while adding cross‑chain bridge adapters, interest‑bearing vaults, and flash‑mint functionality for liquidity providers.Because USDT0 is both a widely used settlement asset and a source of on‑chain liquidity, it is an attractive target for flash‑loan attacks. Attackers can borrow large amounts of USDT0 without collateral, execute a series of atomic transactions, and attempt to:
- Manipulate price oracles used by downstream protocols that accept USDT0 as collateral.
- Exploit re‑entrancy or state‑inconsistency in the token’s upgradeable proxy, bridge, or vault contracts.
- Trigger “flash‑mint” overflow/under‑flow or bypass the
onlyOwnermint/burn checks via crafted calldata.
Our analysis focused on the publicly verified contracts (proxy, implementation, bridge adapters, vaults, and the flash‑mint module) and the interactions with the most common DeFi primitives (AMMs, lending markets, and synthetic asset platforms).
Key Findings
#IssueSeverityLikelihood (per 6‑month window)1UnrestrictedflashMint– no caps, no re‑entrancy guard, and no “max flash amount” check.HighMedium2Bridge “relay” function accepts arbitrary calldata from the L2 side without source authentication → possible replay of malicious L2 messages.HighLow‑Medium3Upgradeable proxy storage clash – new implementation addeduint256 totalFlashMintedthat collides with an existing storage slot used by a legacy vault.MediumLow4Oracle price feed manipulation – USDT0 is used as the base asset for several on‑chain price oracles that rely on AMM TWAPs; flash‑minted USDT0 can distort the TWAP if the mint amount exceeds 0.5 % of pool liquidity.MediumMedium5MissingonlyOwnercheck onsetMinterin the flash‑mint module (owner can be changed via a 2‑step process, but the function is public).MediumLow6Re‑entrancy indeposit()of the interest‑bearing vault – the vault pulls USDT0 viatransferFrombefore updating its internal accounting, allowing a flash‑loan contract to re‑enterdeposit()and inflate its share balance.HighLow7Event emission inconsistency –Transferevents emitted from flash‑mint bypass theERC20Transferhook, breaking downstream analytics that rely on event ordering.LowLow
Overall, the aggregate risk score for flash‑loan attack vectors on USDT0 is 7 / 10 (High). The most critical issues are the unrestricted flash‑mint and the re‑entrancy in the vault’sdeposit()function, both of which can be combined to extract value from downstream protocols.
2. Identified Attack Vectors
2.1 Unrestricted Flash‑Mint (Vector #1)
- Contract:
FlashMintModule.sol(implementation address0x...) - Function:
flashMint(uint256 amount, address receiver, bytes calldata data) - Problem:
- No maximum flash amount or per‑block cap.
- No re‑entrancy guard (
nonReentrantmodifier missing). - The function mints tokens, calls
receiverwith arbitrary calldata, then expects the caller toburnthe same amount before the transaction ends.
- Potential Exploit:
- Borrow $200 M USDT0 via flash‑mint.
- Use the borrowed USDT0 to pump the USDT0/ETH pool on a DEX, skewing the TWAP.
- Trigger a downstream synthetic asset mint (e.g., sUSD) that reads the manipulated price.
- Repay the flash‑mint and keep the synthetic assets, which can be liquidated for profit.
2.2 Bridge Relay Re‑entrancy (Vector #2)
- Contract:
L2BridgeAdapter.sol - Function:
relayMessage(bytes calldata message)– called by the L2 message manager. - Problem: The function does not verify the origin of the L2 message (no Merkle proof verification) and forwards the
messagedirectly toUSDT0viacall. - Potential Exploit:
- An attacker can forge a L2 message that calls
flashMintwith a huge amount, then immediately calls a downstream vault’sdeposit()to lock the minted tokens, preventing repayment before the transaction ends.
- An attacker can forge a L2 message that calls
2.3 Storage Collision in Upgradeable Proxy (Vector #3)
- Proxy:
TransparentUpgradeableProxy.sol(EIP‑1967). - Issue: New implementation added a state variable
uint256 totalFlashMintedat slot 0x3, which previously storeduint256 totalSupplyfor a legacy vault. This overwrites the vault’s total supply during upgrades. - Potential Exploit:
- By upgrading to a malicious implementation that writes a large value to
totalFlashMinted, the attacker can inflate the vault’s share price, allowing them to withdraw more USDT0 than deposited.
- By upgrading to a malicious implementation that writes a large value to
2.4 Oracle Manipulation via Flash‑Mint (Vector #4)
- Oracles: Chainlink‑style TWAP contracts that compute price from USDT0/ETH Uniswap V3 pools.
- Problem: TWAP window is 30 minutes; a flash‑mint of >0.5 % of pool liquidity can shift the price enough to affect downstream lending protocols (e.g., Aave, Compound).
- Potential Exploit:
- Flash‑mint USDT0, add liquidity to the pool, wait for the observation window, then remove liquidity before the flash‑mint is repaid. The temporary price distortion can be used to borrow other assets at undervalued collateral ratios.
2.5 Public
setMinter(Vector #5)- Function:
setMinter(address newMinter)– callable by anyone (noonlyOwner). - Problem: Allows an attacker to appoint themselves as the authorized minter for the flash‑mint module, bypassing any future governance checks.
- Potential Exploit: Once set, the attacker can call
flashMintwithout restriction, effectively turning the flash‑mint into a permanent mint.
2.6 Re‑entrancy in Vault
deposit()(Vector #6)- Contract:
InterestVault.sol - Function:
deposit(uint256 amount)– pulls USDT0 viatransferFrombefore updatinguserShares. - Problem: A malicious contract can implement
receive()that callsdeposit()again, causing the internal accounting to be updated multiple times for the same underlying amount. - Potential Exploit: Combine with flash‑mint to inflate share balance and later withdraw more USDT0 than originally deposited.
2.7 Event Emission Inconsistency (Vector #7)
- Issue:
flashMintemits a customFlashMintedevent but does not emit the standardTransferevent required by ERC‑20. - Impact: Off‑chain analytics (e.g., Dune, The Graph) may under‑report the flash‑mint activity, leading to mis‑priced risk models for protocols that rely on on‑chain data. While not a direct exploit, it facilitates hidden attacks.
3. Prioritized Technical Recommendations
PriorityRecommendationRationaleImplementation SketchCriticalAdd a flash‑mint cap & non‑reentrancy guard (uint256 public maxFlashMintPerTx;+nonReentrantmodifier).Prevents unlimited token creation and stops re‑entrancy chains that could lock minted tokens.

| Medium | Audit and realign storage slots for any future upgrades. Use a storage‑gap (uint256[50] private __gap;) and run a storage layout diff before each upgrade. | Avoids accidental overwriting of critical variables (e.g., vault totalSupply). |
| Low | Emit standardTransferevents fromflashMintandflashBurnto keep ERC‑20 compliance. | Improves transparency for off‑chain monitoring tools. |
| Low | Implement a TWAP safeguard – require a minimum pool liquidity threshold before a price feed can be used as collateral. | Reduces the impact of short‑term price manipulation. |

Flash Loan Attack Vector Analysis: USDT0 -
In this series, I encountered a
pg_duckdbgotcha with unconstrained numeric column. Withduckdb.force_execution = true, I expected DuckDB to run my aggregate. But it ran on the PostgreSQL engine instead, with a warning. Here's how to see it and fix it.Reproduce
I created a table with four columns of the same number, differing only in declared type:DROP TABLE IF EXISTS nf;
CREATE TABLE nf (
id bigint
, n_bare numeric
, n_10_2 numeric(10,2)
, d double precision
);
INSERT INTO nf SELECT g, g+0.5, g+0.5, g+0.5
FROM generate_series(1,100000) g
;
ANALYZE nf
;Here are their Postgres type modifiers (
-1means "no declared precision"):postgres=> SELECT attname, atttypmod FROM pg_attribute
WHERE attrelid='nf'::regclass AND attnum>0 AND NOT attisdropped ORDER BY attnum

The symptom
I forced DuckDB on, then sum the bare numeric:postgres=> SET duckdb.force_execution = true;
SET
postgres=> EXPLAIN SELECT sum(n_bare) FROM nf
;
WARNING: (PGDuckDB/CreatePlan) Prepared query returned an error: Binder Error: No function matches the given name and argument types 'sum(UnsupportedPostgresType(DuckDB requires the precision of a NUMERIC to be set))'

AWARNINGat plan time is emitted whenpg_duckdbtries to build the DuckDB plan and bails on the unconstrained numeric. But it's aWARNING, not an error, easy to miss from an application, and the query still returns the right answer on the native executor. If you were only watching the response time you'd thinkpg_duckdbdidn't help, when it never ran the query in DuckDB at all.I've run the same sum over the

(25 rows)DuckDB runs it. The only difference between the two queries is that one column has a declared precision and the other doesn't.
Why
DuckDB'sDECIMALis fixed precision, up to 38 digits. A Postgresnumericwith a declared(p,s)maps straight onto it. A barenumerichas no bound — there's nothing for DuckDB to map it to — so pg_duckdb leaves the whole query to PostgreSQL. (Anumeric(38,10)works fine, only the unconstrained one falls back.) The fallback itself is a feature: forcing DuckDB can never break a query, it just might not accelerate it. The problem is only that it's silent.The fix
One session setting makes the bare numeric run in DuckDB, read asdouble:postgres=> SET duckdb.convert_unsupported_numeric_to_double = true;
SET
postgres=> EXPLAIN SELECT sum(n_bare) FROM nf

(25 rows)No more warning, and the top node is now
Custom Scan (DuckDBScan)— DuckDB runs it, reading the bare numeric asdouble.The caveat is in the name:
doubleis floating point, so you can lose the exact decimal precisionnumericguarantees — fine for analytical sums and averages, think twice for exact financial rounding. The cleaner fix is to declare the precision in the schema (numeric(12,2)), so DuckDB runs it exactly, no flag.Takeaway
Withforce_execution = true, alwaysEXPLAINand check the top node isCustom Scan (DuckDBScan). If it's a plain PostgreSQL node, DuckDB declined — and a barenumeric(typmod-1) is the usual reason. Declare the precision, or setduckdb.convert_unsupported_numeric_to_doubletotrueif your can accept that decimal fractions that cannot be stored with exact base-10 precision are rounded.Even with
duckdb.force_execution = true, you should always run EXPLAIN to verify that the query utilizes theCustom Scan (DuckDBScan)node. If the planner falls back to native PostgreSQL nodes, it indicates that DuckDB declined the query—most commonly due to an unconstrained PostgreSQL NUMERIC column (with a type modifier of-1). To resolve this, explicitly declare the column's precision and scale, or setduckdb.convert_unsupported_numeric_to_double = trueif your workload can tolerate the inherent precision loss and rounding behavior of binary floating-point (DOUBLE) conversions.#postgres #duckdb #azure #numeric #software #coding #development #engineering #inclusive #community
