Three systems. One brain. Every number has a proof. Every dependency has a map. Every lesson is permanent. No other plumbing company on earth has this.
Three layers that turn scattered data into provable intelligence.
Maps every service, API, timer, database table, person, and KPI as a queryable network. Ask "what breaks if X fails?" and get the answer in milliseconds.
Like a city's electrical grid map. You don't guess which buildings go dark when a transformer fails -- you TRACE the circuit. The graph traces every data circuit in Nexus.
2,808 knowledge chunks with vector embeddings. 28 "brain chunks" encode operational wisdom: error patterns, fix recipes, prevention rules. Zeus searches it in 10 seconds.
Like a surgeon's case history database. Every surgery they've done, every complication they've seen, every technique that worked -- searchable in seconds before the next operation.
Every financial formula exists in 3 formats: LaTeX (proof), Python (automation), Excel (Stephanie). Dimensional analysis catches unit errors. Bounds checking catches anomalies.
Like NASA's triple-redundant flight computers. Three independent systems must agree on every calculation. If any diverge, the mission aborts before the rocket explodes.
54 nodes. 60 edges. The full nervous system mapped.
Blast radius: 9 systems
Blast radius: 14 systems -- everything.
PostgreSQL is the single point of failure. If it goes down: API dies, sync dies, RAG dies, all dashboards blank, all bots fail. Every node in the graph depends on PostgreSQL either directly or through titan-killer.
PostgreSQL is the spinal cord. The graph brain is the nervous system map. Before, we could injure the spine and not know which limbs would go numb. Now the graph shows every nerve path.
2,808 knowledge chunks. 28 brain chunks of operational wisdom.
Every failure that's happened, compressed into searchable knowledge. Phantom revenue, dispatch board empty, auto-tagger dry run, batch edit cascades.
"Before doing X, always check Y." Before revenue queries: check job_status filter. Before editing files: read them first. Before deploying: write to file, SCP, test.
ST tech IDs are local not ST. Vapi PATCH needs full model object. QB tokens expire hourly. WordPress snippets kill the site. 3CX uses OData v1.
Data flow: ST -> Sync -> PostgreSQL -> API -> Frontend. Service map with all ports and timers. Capability maturity levels L1-L5.
job_status filter mandatory. sold_by_id vs technician_id. Exclude cancels. QB is SSoT not ST.
All 11 playbooks chunked and embedded. Field notes (130). SEO keywords (10). Investigation data. Strategy documents.
The RAG brain is like an immune system's antibody library. Every infection (failure) the system has fought creates antibodies (brain chunks) that protect against future infections. The more failures we survive, the stronger the immune response becomes. Auto-tagger was a "virus" -- now the antibody "Before Reporting Working - Check Output" prevents that class of infection permanently.
Every number has a proof. Triple-format validation. Dimensional analysis. Anomaly detection.
\frac{\text{Ad Spend}}{\text{Conversions}}spend / max(conversions, 1)=B2/C2\frac{R_{\text{attr}}}{S_{\text{ad}}}revenue / max(spend, 1)=D2/B2\frac{R - C - O}{R} \times 100((rev-cogs-opex)/rev)*100=((D2-J2-K2)/D2)*100R_p \times \frac{365}{d}period_rev * (365/days)=D2*(365/L2)Every number carries its unit. Invalid operations are caught before they execute.
Dimensional analysis is how physicists catch errors before rockets crash. NASA's Mars Climate Orbiter burned up because one team used pounds, another used newtons. Nobody checked the units. Our math engine checks units on EVERY operation. You literally cannot add dollars to leads -- the system rejects it.
Every number Stephanie sees passed through 5 validation layers.
Root cause: Techs not clicking "Done" in ServiceTitan. Revenue is UNDERSTATED. ST shows $27,949 completed. QB shows $332,943 income. The $305K gap is unclosed jobs.
The trust chain is like a pharmaceutical drug approval process. A drug doesn't go from lab to patient on a hunch. It passes through 5 phases of clinical trials, each one more rigorous than the last. Any phase fails, the drug doesn't ship. Our numbers work the same way -- any layer fails, the number doesn't reach Stephanie.
The anti-scatterbrain system. Minimum context, maximum precision.
50,000 tokens of background dumped into every prompt. CLAUDE.md, memory files, meeting notes, all 40+ memory entries. Claude sifts through noise, misses the signal, edits the wrong file, breaks a downstream system it didn't know existed.
Intent parsed. Graph queried for dependencies. RAG queried for warnings. Math engine checked for applicable formulas. Only the 5-8 relevant nodes injected. Zero noise.
Without the harness, it's like a surgeon reading the entire medical encyclopedia before every operation. With the harness, it's like having a surgical briefing card that shows ONLY the patient's history, the procedure steps, and the known risks. Same surgeon. 10x more precise.
Nexus isn't software. It's a biological system that grows smarter with every interaction.
Tracks its own capabilities across 31 dimensions. Knows what it can and cannot do. Maturity levels L1-L5.
If ad spend spikes or conversion drops, detects the imbalance and triggers correction before it becomes a problem.
28 brain chunks from past failures. Auto-tagger dry run, phantom revenue, batch edit cascades -- all vaccinated against.
2,808 RAG chunks. Compresses raw data into actionable wisdom. Carries across sessions. Never asks the same question twice.
8 timers running 24/7. Rain detected? Alert. Check overdue? DM. Daniel AI call? Intake formatted. Job stale? Closure bot.
$77K/week target. Every metric feeds the 3 equations: Revenue, ROAS, Profit. Recalculates the path every time numbers shift.
One field note becomes blog post, social media, GBP update, email content, ad copy, review response. One input, six outputs.
Graph grows new edges. RAG grows new chunks. Math engine grows new formulas. The system upgrades itself with every session.
Connects Google Ads to ST revenue to weather to reviews. Finds patterns invisible to any single dashboard.
Crashed service? Restarted. Stale data? Refreshed. Token expired? Renewed. Self-healer runs every session.
Plain English interface. Ask Zeus in Slack, get an intelligent answer. No dashboards to learn. No logins to remember.
Revenue trends, seasonal patterns, leading indicators. Tells you next week's problem before it becomes this week's emergency.
