Sentinel Surveillance Dashboard¶
Monitoring dashboard — instantiates Sanctuary-Aware Source Control
Turns a network of early-warning sentinel sites into one live picture of recurrence, so the first sign of reseeding shows up against the replacement line long before the target re-establishes.
Suppression that isn't watched slides back. Sentinel Surveillance Dashboard aggregates the readings from a sparse but well-placed set of sentinel nodes into one continuous, glanceable picture of whether the target is recurring — and it draws the replacement line right on the picture, so a rising signal is read against the threshold that separates fading from re-establishing. Its defining move is to run on leading indicators from a few decisive watch-points rather than a lagging census of everything: the point is to catch reseeding early, at the nodes most likely to show it first, not to confirm a comeback after it has already happened. It is a display and an alarm, not a verdict — it tells the campaign something is moving here, now, and hands off both the formal confirmation of success and the response to others.
Example¶
A measles-elimination program has driven local transmission down and needs to know the instant it starts to creep back. The Sentinel Surveillance Dashboard pulls from a deliberately chosen network — a handful of sentinel clinics in high-mixing districts, plus wastewater sampling at a few catchments — rather than trying to watch every village. On the board, each node shows its recent detections, and a single panel tracks the running effective reproduction number against the R = 1 replacement line: below it, an outbreak fades; above it, it sustains. For weeks the estimate hovers around ~0.8 and the board is green. Then two sentinel clinics in one district tick up together and a wastewater signal turns positive days before any case cluster is confirmed.
The dashboard does exactly one thing with that: it raises the alarm and localizes it — this district, these nodes, trending toward replacement — while everything else stays quiet. It does not declare the elimination over, and it does not decide what to do. It buys the campaign the days of early warning that are the whole point, so the response can reach the reseeding district before the source re-establishes a foothold. Whether local transmission has truly fallen below replacement for good is a formal call made elsewhere; the board's job is to make sure the first flicker is never missed.
How it works¶
- Read a sentinel network, not a census. Draw from a small set of watch-points chosen for how early and reliably they reveal recurrence, rather than trying to see everywhere at once.
- Render recurrence against the replacement line. Show the running recurrence signal continuously with the below-replacement threshold drawn in, so "fading" versus "re-establishing" is legible at a glance.
- Foreground leading over lagging signals. Weight early sentinel movement ahead of confirmed totals, so the board turns before the comeback is obvious.
- Alarm and localize — then stop. When a node crosses trigger, raise and place the alert; the dashboard does not certify success or mount the response.
Tuning parameters¶
- Sentinel placement and coverage — how many nodes and where (high-risk and upstream versus representative). More coverage detects reseeding earlier but costs more and dilutes attention.
- Alert threshold and smoothing — how sensitive the trigger and how much noise is filtered. Tighter triggers catch reseeding sooner at the price of false alarms; heavy smoothing hides early flickers.
- Leading-versus-lagging weighting — how far early sentinel signals are foregrounded over confirmed counts. Lean leading to buy warning time, lagging to reduce noise.
- Replacement-line display — where the below-replacement reference sits and how its uncertainty band is shown. A hard line with no band invites false confidence.
- Refresh latency — real-time versus periodic updates. Faster catches reseeding earlier but amplifies noise and can provoke over-reaction.
When it helps, and when it misleads¶
Its strength is that it compresses scattered readings into a single recurrence signal a campaign can watch, and it delivers the early warning that makes sanctuary-aware control possible — catching a reseed at a sentinel node before it re-establishes across the cleared zones.
Its failure mode is that a dashboard is only as truthful as its coverage: a blind spot reads as "all clear," turning absence of evidence into apparent evidence of absence, and a green board quietly invites premature stand-down. A single reassuring headline can also mask one rising node. The classic misuse is to treat the continuous display as if it were formal proof of success — declaring victory off a green board.[n1] That certification belongs to the Below-Replacement Confirmation Test, not to the dashboard. The discipline that keeps it honest is to annotate coverage and known blind spots on the board itself, and never to let "the dashboard is green" stand in for the formal below-replacement test.
How it implements the components¶
Sentinel Surveillance Dashboard realizes the detection-and-monitoring side of the archetype — the components that watch for recurrence, without judging or responding:
sentinel_node_network— it operates the chosen set of early-warning watch-points as its sensing layer.recurrence_monitor— it is the continuous instrument that renders whether the target is coming back.below_replacement_confirmation_threshold— it displays the running recurrence estimate against the replacement line as a leading indicator — an early-warning read, not the formal certification.
It does not itself certify that regeneration has fallen below replacement — the formal statistical confirmation is the Below-Replacement Confirmation Test's — nor does it model which nodes are sources (the Source–Sink Network Mapping) or mount the response when an alarm trips (the Source Reduction Program and the rebound plan from the Rebound and Reseeding Stress Test).

Editorial Notes¶
Form Classification¶
Form family: Monitoring, Sensing & Alerting
Rationale: Sentinel Surveillance Dashboard operates as ongoing observation, sensing, or alerting that detects and surfaces state without itself executing the response because it turns a network of early-warning sentinel sites into one live picture of recurrence, so the first sign of reseeding shows up against the replacement line long before the target re-establishes.
Independent corroboration: The frozen evidence defines Sentinel Surveillance Dashboard as 'Turns a network of early-warning sentinel sites into one live picture of recurrence, so the first sign of reseeding shows up against the replacement line long before the target re-establishes', so its operative form is Monitoring, Sensing & Alerting.
Review outcome: Independent reviewer agreement; high confidence.
Origin Attribution¶
Primary origin: Biology & Ecology
Origin pattern: Cross-disciplinary synthesis
Present-day reach: Multi-domain
Rationale: Tracking sentinel organisms, populations, or syndromes to reveal hazards before broad harm is a biological surveillance lineage. EPA documents sentinel animals and WHO shows disease-circulation dashboards; data science and HCI operationalize aggregation and display.

Review resolution: The blind reviewers disagree on primary lineage (biology_ecology versus environmental_climate). Authoritative or primary research supports biology_ecology as the best historical origin: Tracking sentinel organisms, populations, or syndromes to reveal hazards before broad harm is a biological surveillance lineage. EPA documents sentinel animals and WHO shows disease-circulation dashboards; data science and HCI operationalize aggregation and display. The cited EPA, Sentinel Animals in Environmental Monitoring; WHO, Disease Circulation Dashboard directly supports the mechanism's defining operation. All independently supported contributing domains are retained without an arbitrary cap. origin_mode=cross_disciplinary_synthesis records the lineage relationship, while domain_reach=multi_domain records later applicability separately from provenance.
Encyclopedia synthesis: The exact catalogued form synthesizes established practice rather than reproducing a single standard historical label.
Review outcome: Researched adjudication after independent review; high confidence.

Notes¶
The dashboard is a leading-indicator surface and is deliberately not the certifier. Keeping display and certification apart is what prevents a green board from becoming a false all-clear: the board says "nothing is moving that we can see," which is only as strong as where it is looking. The formal, slower judgment that recurrence is truly below replacement — with its coverage assumptions made explicit — is the Below-Replacement Confirmation Test's to make.
[n1] The effective reproduction number (Rt) is the average number of secondary cases generated per case at time t; Rt < 1 is the below-replacement condition under which an outbreak shrinks rather than sustains itself. A dashboard can display a running Rt as an early signal, but a point estimate crossing 1 on a board is a prompt to look, not a certification that transmission has been ended. ↩
