Durante OS  /  The Algorithm

One unit of work, watched end-to-end.

Seven phases. Six gates. Every transition leaves a receipt. Below is the canonical playthrough — a real work order, run through every stage. Click any phase in the rail to skip in.

RUN · 0241 · liveCASE / Overdue receivable · Acme Industries · $12,400
PHASE 01 / OBSERVE

Surface the signal the room is missing.

The operator's first job isn't to do — it's to notice. Sweep inboxes, tickets, ledgers, CRM. Cluster, score, name what matters before anyone reaches for a tool.

GateSignal lockedSLA · 12 min
↳ Operator moves
  • 01Cluster raw signals across systems by likely situation
  • 02Score each with a hypothesis + confidence (0–1)
  • 03Surface only the few that change what should happen next
OBS · SHA 9b21a4 · 47 signals → 3 named · top 0.91
INPUTRAW

Mixed signal across systems

  • QuickBooks A/R aging report
  • 34 unread emails — 6 vendor threads
  • Slack #ops · 2 escalations
  • Calendar — board call Thu 14:00
OUTPUTSIGNAL

Acme A/R · 41 days overdue

$12,400 outstanding. Repeat customer, FY24 ARR $89k. Last touch 14 days ago — unanswered. Risk: board call references receivables.

CONF · 0.91 · escalate
Gate ▶Signal locked · proceed to Think
PHASE 02 / THINK

Reason before reaching for a tool.

Multi-LLM debate. The signal is interrogated from three angles. Output: a hypothesis with stakes — not a checklist.

GateHypothesis stated3-model consensus
↳ Operator moves
  • 01Three models debate the same signal independently
  • 02Surface dissent, not just the median
  • 03Output a hypothesis with confidence and risk vector
THINK · SHA 4ce7f2 · consensus 0.78 · "ERP cutover broke A/P"
INPUTSIGNAL

Acme · $12,400 · 41d overdue

Inherited from Observe. Context loaded: last 6 invoices paid on-day-32 avg, two prior late episodes (Q1, Q3).

OUTPUTHYPOTHESIS

"ERP migration broke their A/P workflow"

Confidence 0.78. Stakes: relationship intact, just stuck. Recovery path: re-establish A/P contact, accept ACH retransmission.

RISK · low · ESC · operator-led
Gate ▶Hypothesis stated · proceed to Plan
PHASE 03 / PLAN

Pick the smallest reversible next move.

Plans are written as the receipts that will exist once the work is done. If a step can't produce a receipt, it isn't in the plan.

GatePlan approved4 steps · 2 reversible
↳ Operator moves
  • 01Sequence the receipts that will prove the work landed
  • 02Mark reversibility per step — operator can revoke
  • 03Approval window 4 min · auto-flips to escalated past
PLAN · SHA 1e8a09 · 4 steps · approved 08:36 · operator
INPUTHYPOTHESIS

ERP migration broke A/P

Plus context: contact graph, prior communication tone, payment terms (NET-30), relationship value.

OUTPUTPLAN · v1

Approve · revise · reject

Plan surfaces to operator-of-record in 30s. Default approval window: 4 min. Auto-revisable up to step 03; step 04 requires re-plan.

APPROVED · 08:36 · operator
Gate ▶Plan approved · proceed to Build
PHASE 04 / BUILD

Compose the artifact before sending it.

Build is where artifacts are constructed in a sandbox — drafts, regenerated invoices, calendar holds, briefs. Nothing leaves the system here.

GateArtifact staged3 artifacts
↳ Operator moves
  • 01Compose voice-matched email · attachments · cal block
  • 02Version-pin every artifact in the sandbox
  • 03Open the review pane for operator approval
BUILD · SHA a72c33 · 3 staged · staged · awaiting EXEC
INPUTPLAN

4-step recovery plan

Approved at 08:36. Build pulls: brand voice file, invoice template, ACH instructions, Sarah Cho’s contact history.

OUTPUTSTAGED

Sandboxed · review pane

All three artifacts open in a single review pane. Tone, attachments, recipients, send time — adjustable. Nothing has touched the outside world yet.

STATE · staged · awaiting EXEC
Gate ▶Artifact staged · proceed to Execute
PHASE 05 / EXECUTE

Send. Log. Own it.

The only phase that touches the outside world. Every side-effect is bracketed by a pre-flight and a post-flight receipt — even when it fails.

↳ Operator moves
  • 01Pre-flight check (SPF · DKIM · attachment hash)

INPUTSTAGED

3 artifacts · operator-approved

Final approval at 08:43. Send-window opens. Pre-flight: SPF/DKIM check, attachment hash, contact verification.

OUTPUTEFFECT

The world has changed

Email delivered. Invoice received. Hold on calendar. The system now waits — but it isn’t idle. Verify is already watching for the reply.

STATE · sent · awaiting reply
Gate ▶Side-effect logged · proceed to Verify
PHASE 06 / VERIFY

Match outcome to hypothesis.

The conscience of the system. If the world responded differently than predicted, the delta surfaces — and we re-enter Think.

↳ Operator moves

Reply from Sarah Cho · 09:47

“You’re right — we cut over ERPs and the old A/P queue dropped. ACH sent. Thanks for the nudge — appreciate the heads-up.”

PHASE 07 / LEARN

Codify what the run taught the system.

Learn writes back. Doctrine updates. A new pattern is named. Future runs on the same shape now start with a pre-loaded hypothesis.
