How the work gets made

Every number in this deck was counted off the disk this morning.

What sits between a question and a delivered answer

Work passes down through all five. Nothing skips a layer, including work done at two in the morning.

1. 01Engines — code that computes, instead of judgement that estimatesPhysics, arithmetic and standards implemented once, tested, and called by every project. A number that did not come out of an engine does not go in a document.
2. 02Gates — executable checks that refuse to build a wrong documentRun before the deliverable is produced, not after it is sent. Each gate is tested by planting the defect it is meant to catch, because a gate that has never failed proves nothing.
3. 03The council — six independent models across five vendors, in parallelSubstantive claims are attacked before they ship. Disagreement is settled by running the code or citing the source, never by majority.
4. 04The record — append-only decision logs, audit logs, provenance on every factWhat was decided, when, on what basis, and what it superseded. Never edited — corrections are new entries that preserve the original.
5. 05Delivery — deploy, then prove the deployCompare the local file, the file on the server and a cache-busted fetch. A successful deploy that was never verified once reversed an entire strategy on a stale cache.

Layer one — the engines

The rule that produced them: no project computes its own physics. If the engine lacks something, extend the engine, then import it.

• One engine, imported everywhere — never forkedSix separate implementations of the same reverberation formula once existed across projects. On identical inputs they disagreed by up to 62.6%, and each project had quietly picked its own. Now there is one, and a parity test proves every copy reproduces the reference exactly.
• Extensions are additive and gatedEleven extension modules — speech intelligibility with a direct-field term, absorber design from porous-medium theory, seven-band reverberation, measured loudspeaker coverage, a treatment solver, uncertainty. Each ships with two tests: it must reduce to what it extends, and it must match an independent calculation at twenty or more interior points.
• Measured data beats a class average, alwaysLoudspeaker coverage is computed from the manufacturer's own measured balloon data. A generic model once made a room look ten times worse than it was — the error was in the placeholder, not the room.
• Standards are implemented, not citedISO 9613-1 air absorption per band from temperature and humidity. IEC 60268-16 intelligibility. ISO 3382-1 admissibility gates on measured data. The standard number in a document means the code implements it.

Layer two — gates, and what they have actually caught

Layer three — the council

• Six models, five distinct vendor lineages, asked in parallelOpenAI, Google, xAI, Mistral and Meta. Read agreement by lineages, not head-count — two models from the same vendor share their blind spots and count as roughly one voice.
• Two of the seats can run code to check themselvesWhich is why a derivation from an executable seat outweighs one from a seat that can only reason over the brief it was given.
• Evidence settles disagreement, not the voteThree models against one does not decide anything. The code does, or a cited source does. A measurement three absent members could not overturn outranks a unanimous show of hands.
• A failed seat gets a row saying why“Not consulted” and “could not be consulted” are different facts and never share a row. A seat that is never called is a seat whose defects are never found.
• And it earns its keep on the things that matterOn this week's work a seat built its unit economics on a prime rate of 8.5%. The actual rate was 6.75%, from the Federal Reserve's own series. Another asserted a federal filing obligation that had been permanently ended a month earlier. Both would have been false claims in front of people who check.

Layers four and five — the record, and proving delivery

• Every fact carries where it came fromSourced with a link · primary, quoted from the statute or the data series · a decision we made · or deliberately absent with the name of who to ask. There is no fifth category, and an absent line is never filled with an industry average.
• Decisions are append-onlyA decision log where nothing is ever edited. A correction is a new row that names the row it supersedes and preserves the original claim, so the reasoning survives being wrong.
• Audit logs record the instrument, not just the resultA search that reports nothing has told you about your search, not about the world. Four such findings in one session were wrong: a grep that could not follow symlinks, a scan whose perimeter was never stated, a cost priced without listing the directory, and a pipeline read from the wrong end. A negative finding is not reportable until the search has been made to succeed once.
• Deploys are verified three waysThe local file, the file on the server, and a cache-busted fetch — compared by checksum. This deck's own deployment was verified that way before this sentence was written.
• And the result is always something you can look atFindings come back as a page you can scan in ninety seconds, with the action and the open question separated from the detail — never as a wall of text.

Six implementations of the same formula, disagreeing by 62%.

So one engine was built, and everything else imports it

What is inside it

• Reverberation by four analytic models, plus a geometric solverSabine, Eyring, Fitzroy and Arau-Puchades, plus an image-source simulation. Where they disagree the spread is reported as information rather than hidden — and the geometric model is used where placement matters, because the analytic ones have no term in which placement could appear.
• Speech intelligibility with a direct-field termBuilt to IEC 60268-16. The first version combined direct and reverberant sound as plain numbers when they add as complex amplitudes — optimistic by up to 0.094 in exactly the conditions a reverberant hall occupies. The adversarial review caught it; the fix ships with an interior test at 27 points.
• Absorber design from first principlesPorous medium, perforated facing, impedance stack, random-incidence averaging. Written after a borrowed absorption table was found being applied to a cavity six times deeper than anything it was measured on — the table carried that assumption silently, where a formula carries it visibly.
• Loudspeaker coverage from measured dataThe manufacturer's own measured directivity, not a smooth approximation. It resolved a false alarm: a placeholder model had made a room look ten times less uniform than the measured data showed.
• A treatment solver with per-band corridorsIts first version averaged two frequency bands and reported a room as solved while one of those bands was outside its own limit — and under-prescribed by roughly twenty times on a real hall. It now rejects any target reachable only on average.

Which is why the system is the asset, not any one study.

SUKAR — acoustic simulation engine

A room-acoustics engine written from the physics up: reverberation by four analytic models plus a geometric image-source solver, room modes, speech intelligibility to IEC 60268-16, air absorption to ISO 9613-1, loudspeaker coverage from measured manufacturer balloon data, absorber design from porous-medium theory, and a treatment solver that sizes material per frequency band.

SAE — the Python engine port

The same physics in Python so it can run inside report builders and data pipelines, held to the JavaScript to within 1e-9 by automated parity tests. Two engines that disagree are worse than one; the tests are what stop that happening.

The council — six models, five vendor lineages

Before anything ships, the substantive claims are put to six independent models across OpenAI, Google, xAI, Mistral and Meta, in parallel, each writing its own receipt. Disagreement is resolved by running the code or citing the source — never by counting votes. Two of the seats can read files and run programs to check themselves.

Gates — code that refuses to ship a wrong document

Executable checks that run before a deliverable is built: does the specification prose match the locked design, do the quantities in the drawing match the schedule, is every figure traceable, does the Arabic contain the defects Arabic acquires when it is translated rather than written. A gate that has never been made to fail proves nothing, so each one is tested by planting the defect it is meant to catch.

Deal-flow ledger and billing platform

Every opportunity, quoted or declined, in one file with its own identifier; a billing registry that syncs from it every three hours and never overwrites a status a human has advanced; and an inbox watcher that files pricing-relevant email as draft rows needing review rather than guessing.

Publish Gate — approval before anything goes out

A post-approval checkpoint with an append-only ledger: work is scored against a written standard before it is published, and the record of who approved what cannot be edited afterwards.

Mission control — one map of everything in motion

A single index of every project with its infrastructure facts written by one feeder every four hours and its live status written by another every thirty minutes, reconciled so neither silently overwrites the other.

Contractor-executable engineering studies

Bilingual acoustic and audio-system studies with drawings, bills of quantity, commissioning criteria and vendor handoff packs — built so a contractor can price and build from them without asking a question.

TechTown Damascus — a full digital estate

Website, brand system, media production, campaign material and an acoustic programme for a technology campus — the largest single body of work on the disk.

Naming, identity and campaign platforms

Complete brand systems built from a strategic platform rather than a mood board: the name, the trademark screen, the marks in vector, the identity in use across the surfaces it will actually live on, and the campaign lines that carry it.

Websites, built and hosted

Design and build, deployed on infrastructure I run, with certificates, security guards and version control — not handed to a hosting company and forgotten.

Institutional Arabic that was written, not translated

Arabic composed from the fact rather than from the English sentence, with a grep-able gate that catches the constructions translation produces — the propped-up verbal noun, the calqued aphorism, the dead metaphor — plus Arabic-Indic digits and Levantine months as house style.

score-craft — music written as code

Original composition and arrangement produced as notes, harmony and counterpoint in code, then rendered through sampled instruments to MIDI, stems and a mixdown. Not a generative audio toy — it writes the score.

Film, campaign and launch video

Direction, edit, sound design and delivery — 25 years of audio engineering behind the mix.

Public-address and AV system design

Coverage, intelligibility and level uniformity computed from measured loudspeaker data — then specified, procured, commissioned and measured against the prediction.

The menu, on one page

Ranges are for orientation. Nothing here is a quotation, and every real figure follows a scope conversation — a price given before the brief is read is a guess with a dollar sign on it.

From a question to something you can act on

1. 01The brief gets read before it gets pricedFour separate defects in one quotation last year all traced to pricing before reading. Attachments opened first, then the number.
2. 02The facts get separated from the assumptions, in writingWhat is sourced, what is a decision, what has to be measured, and what is missing. You see this list before any work starts.
3. 03Engines and gates do the arithmeticNothing hand-computed. Nothing hand-transcribed — a hand-copied air-absorption model once failed validation by 0.284 seconds.
4. 04The council attacks itBefore you see it, not after.
5. 05It ships as something you can read in ninety secondsThe answer, the action and the open question first; the detail underneath for whoever needs it.
6. 06And the delivery is provenChecksums, a cache-busted fetch, and a line in the log saying what was checked and with what.
