SECTOR 305

Miami on the map. Console on the glass.
A doctrine-driven fictional PSAP dispatch simulator where process—not spectacle—decides the watch.

South Beach swagger at the door. A ruthless instrument on the glass.

What the hell is this?

SECTOR 305 is a deterministic emergency-communications training simulation set inside a fictional Miami-area public-safety answering point. You work the A-console: own the queue, verify imperfect locations, classify priority, build the response, protect airtime, obtain readbacks, maintain unit status, and leave a defensible record.

The simulation does not grade whether the story had a heroic ending. It grades whether your process held together under pressure.

This is not an arcade city-management game, a production CAD, or an official certification product. It is a deep fictional training instrument built to make operational discipline playable.

The glass

The console puts the full watch in one coherent instrument:

Priority-and-age incident queue with imperfect information
CFS classification, location confidence, safety flags, and radio composition
Police, fire, EMS, air, hospital, and special-use presentation boards
Last-known unit tracks over a layered Miami GIS sector plate
Fictional built-in channel bank with a clean local-adapter seam
Live hard-fail and coaching feedback
Keyboard-complete checkride path
Original title music featuring David Lombardo on lead guitar
Seventeen-track original scenario score with automatic radio ducking
Dedicated score desk: on/off, previous/next, direct track selection, and bed level

Music that knows when to get out of the way

The title performance crosses into a rotating watch score when the console opens. Seventeen original David Lombardo tracks are leveled for background use, looped per watch, and automatically ducked beneath dispatch and unit traffic. The score desk exposes the whole catalog without mixing music controls into the radio path.

The loop that remembers

SECTOR 305 carries performance forward without points, streak bait, or fake credentials. Every completed watch updates a local mastery record. Doctrine findings become operational domains—location, priority, assignment, status, radio, tempo, documentation, safety, multi-call awareness, and information constraints.

The next launch arrives with one explicit objective:

WATCH DIRECTIVE · LOCATION
Verify before you launch.

A clean follow-up watch does not erase the lesson. It converts the objective into retention: prove that the discipline still holds under pressure.

Pass clean—or learn exactly why you did not


Qualified Zero hard fails. The next watch asks you to hold the standard.	Corrective Evidence-backed failures become the next watch's operating focus.

Why it hits differently

System	What it means in the watch
Deterministic simulation kernel	The same seed and command stream reproduce the same evaluation.
Information-set fairness	Hidden scenario truth cannot grade you until the relevant cue becomes knowable.
Doctrine packs	Priority, statuses, assignment, radio, location, and rubric law are data-driven.
Sacred replay artifact	A `SessionRecord` stores commands; the engine re-derives state and the debrief.
Adaptive mastery	Persistent findings shape the next objective without turning performance into points.
Restrained presentation	Neon belongs to the shell. The live CAD uses EFIS-like semantic color.
Authentic texture	City GIS atmosphere, imperfect last-known mapping, fictional channels, and an original Miami score ground the fiction.

Pass clean—or learn exactly why you did not


Qualified Zero hard fails. The next watch asks you to hold the standard.	Corrective Evidence-backed failures become the next watch's operating focus.

Why it hits differently

System	What it means in the watch
Deterministic simulation kernel	The same seed and command stream reproduce the same evaluation.
Information-set fairness	Hidden scenario truth cannot grade you until the relevant cue becomes knowable.
Doctrine packs	Priority, statuses, assignment, radio, location, and rubric law are data-driven.
Sacred replay artifact	A `SessionRecord` stores commands; the engine re-derives state and the debrief.
Adaptive mastery	Persistent findings shape the next objective without turning performance into points.
Restrained presentation	Neon belongs to the shell. The live CAD uses EFIS-like semantic color.
Authentic texture	City GIS atmosphere, imperfect last-known mapping, fictional channels, and an original Miami score ground the fiction.

Run the watch

Requirements: Node.js 20 or newer.

git clone https://github.com/coldbricks/SECTOR-305.git
cd SECTOR-305
npm install
npm run dev

Open http://127.0.0.1:3050, let the title track breathe, then select BEGIN.

Useful commands:

npm test# core invariants and doctrine behavior
npm run test:e2e # full browser acceptance
npm run typecheck # strict TypeScript
npm run build # production build
npm run validate:packs # doctrine-pack validation
npm run sim -- fail # intentional five-finding checkride
npm run sim -- pass # clean canonical checkride

Verification posture

Current local milestone:

107 core assertions across 17 test files
10 end-to-end browser scenarios
Deterministic pass/fail simulation demos
Pack validation covering 14 natures and 24 rubric rules
Responsive acceptance at 1471px, 1280×720, and 760px
Native keyboard controls, focus visibility, reduced-motion support, and protected radio intelligibility

CI repeats typechecking, core tests, production build, pack validation, both simulations, and Playwright acceptance.

Data, audio, and attribution

Geographic atmosphere is curated from City of Miami GIS Open Data and remains explicitly non-operational.
SE305 zones, units, incidents, doctrine, and scenario truth are fictional training content.
The public channel bank is independently authored fictional training data. Premium third-party radio exports are absent from the public history.
Original music: “Dispatch in Miami” plus seventeen unique scenario-score masters by David Lombardo.

See THIRD_PARTY_NOTICES.md for the publication boundary.

Safety and honesty

SECTOR 305 is a fictional training simulation. It is not affiliated with the City of Miami, Miami-Dade County, any PSAP, RadioReference, APCO, NENA, or IAED. It is not a substitute for agency policy, supervised training, or production dispatch software. Completing an in-product track grants no real credential.

The highest-value contribution is adversarial operational review. If a grade is unfair, a doctrine rule is incoherent, or the console teaches the wrong habit, open an issue with reproducible evidence and the relevant scenario clock.

SECTOR 305

Miami on the map. Console on the glass.
A doctrine-driven fictional PSAP dispatch simulator where process—not spectacle—decides the watch.

South Beach swagger at the door. A ruthless instrument on the glass.

What the hell is this?

SECTOR 305 is a deterministic emergency-communications training simulation set inside a fictional Miami-area public-safety answering point. You work the A-console: own the queue, verify imperfect locations, classify priority, build the response, protect airtime, obtain readbacks, maintain unit status, and leave a defensible record.

The simulation does not grade whether the story had a heroic ending. It grades whether your process held together under pressure.

This is not an arcade city-management game, a production CAD, or an official certification product. It is a deep fictional training instrument built to make operational discipline playable.

The glass

The console puts the full watch in one coherent instrument:

Priority-and-age incident queue with imperfect information
CFS classification, location confidence, safety flags, and radio composition
Police, fire, EMS, air, hospital, and special-use presentation boards
Last-known unit tracks over a layered Miami GIS sector plate
Fictional built-in channel bank with a clean local-adapter seam
Live hard-fail and coaching feedback
Keyboard-complete checkride path
Original title music featuring David Lombardo on lead guitar
Seventeen-track original scenario score with automatic radio ducking
Dedicated score desk: on/off, previous/next, direct track selection, and bed level

Music that knows when to get out of the way

The title performance crosses into a rotating watch score when the console opens. Seventeen original David Lombardo tracks are leveled for background use, looped per watch, and automatically ducked beneath dispatch and unit traffic. The score desk exposes the whole catalog without mixing music controls into the radio path.

The loop that remembers

SECTOR 305 carries performance forward without points, streak bait, or fake credentials. Every completed watch updates a local mastery record. Doctrine findings become operational domains—location, priority, assignment, status, radio, tempo, documentation, safety, multi-call awareness, and information constraints.

The next launch arrives with one explicit objective:

WATCH DIRECTIVE · LOCATION
Verify before you launch.

A clean follow-up watch does not erase the lesson. It converts the objective into retention: prove that the discipline still holds under pressure.
