Regular expression for validating CAS (Chemical Abstracts Service) numbers. Matches the standard format of three segments: 2-7 digits, 2 digits, and 1 checksum digit.

PostHog single-event capture path, appended to the configured host.

Self-imposed cap on the length of a text property value, from config.json (analytics.paramValueLimit). Not a PostHog limit (its ceiling is ~1MB) — a privacy guard bounding how much of a search term or error message can leave the device.

Self-imposed cap on how much of a React component stack rides along in a $exception event, from config.json (analytics.componentStackLimit). Unlike JS stack frames (capped by count via STACKTRACE_FRAME_LIMIT), a component stack is one unstructured string, so it's bounded by length.

A JSON-safe value a PostHog event property may hold — the primitives trackEvent always accepted, plus arrays/objects for structured properties like $exception_list.

Serializable subset of RequestInit accepted by backgroundFetch. Only structured-cloneable fields are supported; body must already be a string (callers stringify JSON themselves).

A fully-assembled diagnostics snapshot, ready to render into a report.

Where a captured error originated: a global window/worker hook, an unhandled promise rejection, React's error hooks, an aggregated supplier-search failure, or a callback-style chrome.* API call that set chrome.runtime.lastError.

A single captured exception, trimmed to what a bug report needs.

Minimal metadata stored for each excluded product so the user can review (and eventually un-exclude) their ignore list from settings.

Map of exclusion-key → excluded product entry, as persisted in the excludedProducts IndexedDB object store (via @/utils/idbCache).

Response type that extends the standard Response with additional properties for data and request hash tracking.

Re-exported from ./fetch so callers can reach the request helpers through a single entry point.

Three days in milliseconds — the default freshness window for a cached response.

Options controlling a withTtlCache wrapper.

A single schema.org entity — a JsonObject that normally carries an @type (and, at the top level, an @context). Every Thing in schema.org is modelled this way.

Extracts, normalizes, and queries schema.org JSON-LD found on a page.

Construct it from a DOM (or DOM-like) document with SchemaOrgData.fromDocument, or from already-parsed objects with SchemaOrgData.fromNodes, then use the query helpers (get, first, all) or the type-keyed toNested view.

The result of resolving a structure (SMILES or InChIKey) to searchable identifiers.

Selectable window for the stats views.

Ordered range options for the dropdown, each with its i18n label key. Ordered widest-to-narrowest so the default (all) sits first.

Health verdict for one supplier over the selected range.

The per-supplier counters the classifier reads.

Release-update detection.

Two independent paths, chosen by getInstallSource:

• manual / unpacked (and Firefox/AMO) — the browser never auto-updates, so we poll the GitHub releases API and point the user at the release page.
• Chrome Web Store — Chrome stages the update itself and fires chrome.runtime.onUpdateAvailable in the service worker; nothing here runs.

How long to wait between GitHub release polls on the manual-install path.

How long "Later" suppresses the update prompt before it re-prompts. Sourced from config.json (updatePrompt.snoozeHours).

How the running extension was installed.

One group of release-note bullets, e.g. everything under an ### Added heading.

A newer release than the one currently running.
