📝 Walkthrough

Walkthrough

Documents sub-second finality as live on TON mainnet, adds TonAPI Streaming API compatibility/auth notes across streaming docs, restructures the API overview into polling and streaming sections with reference links, and adds a casing override for TonAPI in spellcheck config.

Changes

Cohort / File(s)	Summary
Spellcheck Configuration \.cspell.jsonc	Added spelling override mapping TONAPI->TonAPI to enforce preferred casing in Markdown/MDX.
API Overview ecosystem/api/overview.mdx	Replaced single comparison table with separate Requests (polling) and Streaming tables; converted inline URLs to reference-style link targets and expanded the References section.
Streaming Compatibility Notes ecosystem/api/toncenter/streaming/overview.mdx, ecosystem/api/toncenter/streaming/sse.mdx, ecosystem/api/toncenter/streaming/wss.mdx	Inserted notes stating TonAPI provides compatible SSE/WebSocket streaming endpoints, listed example mainnet/testnet URLs, and clarified that Ton Console API keys are used for authentication.
Sub-second Finality Status & Guidance ecosystem/subsecond.mdx	Updated status to live on mainnet (Apr 9, 2026), reworded status/throughput guidance (including ~6.25x indexer throughput), broadened streaming guidance to include TonAPI, adjusted self-hosting and recommended stack instructions and endpoints.

🐇 A hop, a stream, the blocks align,
TonAPI sings in matching time,
Docs split neat and spellings bright,
Mainnet's quick — the world takes flight! ✨

Check name	Status	Explanation	Resolution
Out of Scope Changes check	⚠️ Warning	The PR includes a minor out-of-scope change: a spellcheck configuration update in .cspell.jsonc adding TONAPI->TonAPI mapping, which is not directly required by issue #2069.	Consider removing the .cspell.jsonc change or document its necessity, as it appears unrelated to the primary objective of updating sub-second finality documentation.

In `@ecosystem/subsecond.mdx`:
- Around line 17-23: Replace ambiguous "today" labels and compact timing units
in the table and nearby text: change strings like "Mainnet today" and "Testnet
today" to an explicit date label (e.g., "Mainnet (YYYY‑MM‑DD)" / "Testnet
(YYYY‑MM‑DD)") and normalize unit spacing to SI-style with a space (e.g., "400
ms" not "400ms", "2.5 s" not "2.5s", "~0.4" -> "~0.4 s" where appropriate).
Update the table rows and any other occurrences (including the other instance
noted around line 25) so all timing values consistently use spaced units and the
relative "today" wording is replaced by the chosen explicit date label.
