An add-on's storage.get read and parsed its whole store file on every call,
and storage.set read, parsed and rewrote it — synchronously, on the main
thread. Traced on a real profile (installed 0.3.70): with a 7.5 MB Aegis
store, 30 of the first 35 s of main-thread time went to storage.get, the
window sat in "Not Responding" from 3 s to 19 s, and the first page showed at
19 s. One get cost ~73 ms; Aegis does dozens per state update.
lib/addon-store.cjs keeps one in-memory copy per store, shared by the
add-on's api.storage (addons-host.js) and its pages (addon-storage-* IPC in
main.js). After a one-time load a get costs microseconds; values are copied
in and out (structuredClone), so callers keep the old semantics. Writes are
coalesced (100 ms) and land as temp-file + rename, and are flushed on quit;
a store that doesn't parse is moved aside instead of being replaced by {}.
Measured on copies of the same profile, dev build:
first page 16.9-17.6 s -> 1.5-1.7 s; main thread blocked 24.7-25.8 s of
30 -> 1.0-1.1 s; longest freeze 13.7-15.0 s -> 0.6 s.
The Aegis side (capping its unbounded txCache) ships separately through
Aegis's own update channel. The boot tracer gains total/longest block columns.
The browser — the consumer face of the stack. Native .bch support with the
resolver built in, so a user installs one app instead of modifying their
operating system. Named for the thread through the labyrinth: the chain is the
thread.
Scope
Electron shell (Chromium engine, no forking): tabs, address bar, history.
In-process .bch resolution — no system daemon, no NRPT, no OS
trust-store changes; reuses bns.js from the BNS repo as a library.
Record handling: h render, ip connect, p/s3 via in-app gateway,
u redirect.
TLS via cert-verify hook (Electron setCertificateVerifyProc) against the
BNS root / on-chain tls fingerprints — no OS store touched.
Provenance indicator: shows whether a page came from the chain / Sia / a
direct server, with NFT category and record type — the decentralized padlock.
Status: not started
Build it in its own session/repo. The ready-to-paste brief is
BROWSER-PROMPT.md (a reference copy in this folder; canonical source is
D:\Dev\NameCoin\BROWSER-PROMPT.md — if they diverge, NameCoin wins). It points
here and reuses the resolver core. theseus.bch is registered and should
eventually serve the browser's own homepage over the protocol it implements.
