Audit roadmap

Latest reliability review: 2 October 2026 end-to-end audit. The paired 0.15.3 / 0.6.3 patch addresses ingest indexing, region aliases, replay, redraws, shutdown and installation identity. Exact-commit Actions and release receipts determine delivery status; older rows below are historical.

Latest UI review: 2026-09-13 audit and refinement. The paired refinement implements A07, A08, A10 and part of A09, with layer organization and scoped reset; release evidence is separate.

Updated: 12 September 2026. This roadmap turns the end-to-end audit into tracked delivery work. Audit IDs A01–A12 are retained; F IDs track features and R IDs track validation risks.

This is the worldwide source-release roadmap. Shared work is paired with CartoLite Canada; A04/O1 is tracked upstream and is not an operator rollout for this repository.

Status and completion rules

• Planned: accepted direction, implementation has not started.
• Active: current work package.
• Implemented: code and regression coverage are present; merge, release and runtime evidence are tracked separately below.
• Review: implementation and regression checks are in a pull request; consult its exact-commit Actions checks.
• Done: merged with passing checks. Release/deployment is recorded separately.
• Needs setup: an external configuration, provider choice, or physical test is required.

Each item needs its acceptance check, edition parity, and an exact CI result before it becomes Done. Code completion does not imply a production rollout. All build/test execution for roadmap work uses GitHub Actions. Fixtures must be synthetic.

Milestones

Milestone	Status	Deliverable / exit condition
M1 — Security and data correctness	Implemented	A01, A02, A03, A05 and A06 are implemented in the paired corrective release. Merge/release requires the existing full CI plus focused regressions in both editions.
O1 — Canada recovery operations	Needs setup	A04 and R09; independently verifiable backup, isolated restore, monitoring, and current deployment identity. This is a separate Canada operations package.
M2 — Usability and portable operation	Planned	A07–A12; honest count/window labels, optional storage, keyboard continuity, readable mobile counters, dependency/release policy, and identifiable worldwide installs.
M3 — Follow and display refinement	Planned	F01–F08; area-constrained follow, readable cards, shared display/motion controls, layer strengths, camera controls, cross-view selection and bounded discovery/focus.
M4 — Optional additions	Planned	F09–F12; bookmarks, ground elevation context, configured tile types and localization/exhibition polish. Provider-dependent work follows A01 and R08.
V1 — Resilience and scale evidence	Planned	R01–R09 exercised where their related code changes; improve measured bottlenecks and preserve privacy, rendering and runtime budgets.

Corrective backlog

ID	Priority	Scope	Status	Work and acceptance
A01	P1	Both	Implemented	Upgrade MapLibre 5.19.0 to patched 6.4.1, adapt ESM imports and bundled worker setup, and scan runtime dependencies from the lockfile. Exact-revision type/build, map, terrain, route-layer, recovery and browser gates pass. Track WebGL2 as the map minimum.
A02	P1	Both	Implemented	Check source-prefix uniqueness before checking coordinates. A positioned/unpositioned collision never creates a guessed origin leg; independently resolved downstream hops remain visible.
A03	P1	Both	Implemented	Coalesce capacity-eviction resets after an authoritative snapshot. Crossing node/route caps leaves the browser consistent and bounded, with no dangling endpoint references or reset per packet.
A04	P1	Canada	Needs setup	Configure the documented encrypted off-host backup and restore path. Prove a checksummed isolated restore with the matching image/version and independent monitoring; preserve production throughout validation.
A05	P2	Both	Implemented	Reject non-finite RF/coordinate values and impose a bounded MQTT envelope before normalization. Synthetic invalid numbers and over-limit JSON/hex are rejected; valid RSSI-only and SNR-only packets still work.
A06	P2	Both	Implemented	Run retention maintenance during quiet periods and avoid unnecessary checkpoint writes. With no new messages, expired routes/nodes leave the API, checkpoint and connected client; quiet connected feeds remain ready.
A07	P2	Both	Implemented	Label cumulative observation totals honestly and describe windows as “links heard within this period.” Never imply current totals are unique packets counted within the chosen interval.
A08	P2	Both map pages	Implemented	Guard access to browser storage itself and fall back to in-memory preferences. A throwing storage getter cannot prevent startup or control use.
A09	P2	Both	Planned	Transfer keyboard selection focus to details, restore it on close, add Netgraph keyboard pan/zoom/reset, and bounded node/area browsing. Find → details → neighbour → close works without a pointer.
A10	P2	Both Netgraphs	Implemented	Give every phone counter a visible or accessible name; prefer a concise nodes/links summary with optional area/component detail. Validate at 320–480 px without overlap.
A11	P2	Both delivery processes	Planned	Make dependency contributions testable without production credentials, retain trusted provider verification, enforce worldwide exact-revision merge/release checks and enable dependency alerting. M1 covers the runtime lockfile scan and automatic publication of the verified manual-run status on the exact commit; repository enforcement and alerts remain planned.
A12	P2	Worldwide	Planned	Improve setup identity, require an instance-specific MQTT client ID, and refresh upgrade/rollback instructions. A documented install reports its actual revision/version; independent instances have distinct identities.

P1 means next corrective work; P2 means the next refinement cycle. MapLibre advisory GHSA-jrc7-96c5-q579 affects the audited dependency. The audit established the vulnerable version, not exploitation of this application.

Feature backlog

ID	Milestone	Status	Feature and acceptance
F01	M3	Planned	Follow scope: Everywhere / This area / Selected node, plus confirmed-routes-only. Keep ten seconds as the default; a locked area never expands just because the camera moves. Expose existing selected-node filtering clearly.
F02	M3	Planned	Follow card: Hold, Next and Inspect, observation age, and a distinct observer-only state. Hold/pause stop an active camera ease; Inspect opens existing details and pauses the director.
F03	M3	Planned	Shared Display menu: interface theme, motion, text size and contrast across Map/Netgraph; Calm / Standard / Showcase presets and recoverable custom settings. Preserve OS reduced-motion preferences.
F04	M3	Planned	Independent effect strength: historical lines, packet glow, residue duration and heat strength. Reducing decoration keeps confirmed links available and sharp at distant zooms.
F05	M3	Planned	Terrain/camera controls: compass/reset north, scale, optional pitch, clearer shading vs 3D-height terminology, and zoom-aware terrain contrast. Labels and packet cores remain readable.
F06	M3	Planned	Map ↔ Netgraph continuity: open the selected public node in the other view; preserve useful context and explain nodes absent from that route window.
F07	M3	Planned	Local discovery: role, recently-seen and current-view filters with bounded empty-query browsing; worldwide grid filtering. Filters use downloaded public data and have an obvious reset.
F08	M3	Planned	Netgraph focus: isolate an area/component, mute unrelated decoration, and reduce competing traffic badges. Keep an obvious all-areas reset and preserve all underlying links.
F09	M4	Planned	Local bookmarks / shareable views: named centre/zoom/bearing/pitch/display presets. Shared URLs contain public view settings only, never private configuration or transient packet identifiers.
F10	M4	Planned	Ground elevation context: on-demand approximate ground height and endpoint height difference, optionally a selected-route profile. Remove visual exaggeration from numeric values and handle missing DEM data. Never present it as antenna height or RF coverage.
F11	M4	Needs setup	Actual tile types: operator-configured satellite/hybrid or another approved provider, after A01. Require explicit attribution, credential handling, allowed hosts, contrast and failure fallback. No provider entitlement is assumed.
F12	M4	Planned	Locale / exhibition polish: English/French Canada chrome, extensible worldwide translations, native locale formatting and selectable units; exhibition and explicit keep-awake preferences using existing patterns.

M3 uses existing public data and browser-local settings. M4 terrain features use the existing DEM on demand; additional tile providers require configuration. Route coverage, antenna height, raw RF details and historical interval totals cannot be inferred from the present public state.

Evidence and engineering backlog

ID	Status	Validation / improvement
R01 — Date-line follow	Planned	Test both directions across 179°/−179° in pitched/rotated Follow at detail zoom, desktop and phone. Existing overview seam coverage does not prove this combination.
R02 — Time and replay	Planned	Separate receipt freshness from RF observation age; test out-of-order/future timestamps, retained MQTT messages and browser clock skew. Old/replayed observations must not masquerade as new activity.
R03 — Backend hot path	Planned	Profile sustained ingest at 10k nodes / 20k routes. Reduce whole-node scans in public-ID refresh only with measured evidence and unchanged identity semantics.
R04 — Recovery pressure	Planned	Test concurrent resync, stream capacity refusal and slow state readers; add bounded response work and retry jitter where justified.
R05 — Live event validation	Planned	Validate event shape and sequence before store mutation, reuse existing validators, and recover once on a malformed stream.
R06 — Budget / parity	Planned	Track page-entry and lazy assets alongside total bytes; extract cohesive helpers as touched. Record intentional Canada/worldwide differences and check shared fixes for drift.
R07 — Browser / device coverage	Planned	Add focused Firefox/WebKit evidence where feasible and physical Android GPU, sleep, audio and thermal checks for Canada. Browser emulation is not hardware validation.
R08 — Degraded services	Planned	Exercise basemap-key failure, DEM timeout, region-asset failure and missing WebGL2 independently. Retain useful status/data and explain unavailable features concisely.
R09 — Operational policy	Needs setup	Verify independent monitoring and off-host restore; document the response to lifetime drop alarms and distinguish present pressure from past drops without silently clearing the alarm.

Delivery and parity record

The audited baselines were Canada 0.12.0 (2e827a4) and Worldwide 0.3.1 (6a446ee). M1 is delivered through Canada PR #70 and Worldwide PR #9, targeting releases 0.12.1 and 0.3.2. Use those PR checks and release manifests for exact revisions and validation results.

The migration measured 474,482 compressed JS/CSS bytes for Canada and 446,084 for Worldwide in Actions, including the new 129,701-byte map worker. M1 now enforces total, non-map-worker, and map-worker caps separately. R06 still tracks entry-page/lazy-load measurement. Rendering timing and topology-count gates are unchanged.

For each work package, record its PR, exact checked commit, CI result, counterpart PR or scope exception, and any release/runtime proof. A green candidate PR remains Review until merged; a merged change remains undeployed until an exact release is rolled out and verified.

Preserve public schema v2, conservative route resolution, the single-service/atomic-checkpoint architecture and hardened runtime. Canada keeps its published-image promotion path, geographic scope, Labs and Android. Worldwide adds a prebuilt amd64/arm64 image distribution with coordinate-derived areas, optional exact region filtering, and no Canada-only data, Labs or Android.

Current visual and Docker release package

Active work: Canada 0.14.0 (PR77) and Worldwide 0.5.0 (PR12). This package delivers shared scene/interface themes, six route presets with advanced controls, readable light/dark palettes, adaptive terrain strokes, desktop buildings/camera controls, and Canada region fills/legend. Worldwide additionally gains key-free default maps, runtime provider configuration and tested native Docker image publication.

This covers the theme/preset/contrast parts of F03, line/glow/residue controls in F04, and the camera/shading parts of F05. Their remaining text-size/motion/heat-strength work and the other follow/discovery features remain on the roadmap. R08 gains missing-tile recovery coverage; broader degraded-service scenarios remain tracked. A passing candidate remains unreleased until exact-commit main validation, release verification and applicable live deployment checks complete.
