Replace the header/status-bar layout with a full-height writing column
plus an always-visible side panel holding all metadata. Canonicalize the
new region vocabulary in CONTEXT.md (Writing column, Side panel) and retire
header / status line / edit area as terms-to-avoid.
Consequent sweeps: rewrite the Error UX section in side-panel terms and
give keyboard-disconnect a home (⌨ ✗, disconnect-only); drop the "line N"
readout; reconcile the render module ops and region shadow; sweep the
status-line/edit-area wording across the technical, roadmap, qfd, notes,
README, and ADR-003 docs (incl. the ~11→~13 line-count figure).
The old ADR documented the specific panel choice (GDEY0579T93 + DESPI-c579)
as if it were a freshly weighed option, but the hardware was already on
hand — the real architectural decision was choosing the medium (e-ink over
FSTN graphical / Sharp Memory LCD / OLED-TFT). Rewrite the ADR around the
medium with the panel as instantiation, note the Freewrite Alpha (2023)
data point as honest expectation-setting, and propagate the anchor /
narrative changes through qfd.md, v0.1-mvp-product.md, and README.md.
Two coupled changes that emerged from one /deep-design session, both touching
the same v0.1 paragraphs:
(1) Align Ctrl-G with the user's existing gct shell alias: git add . ->
short-circuit if nothing staged -> commit with an ISO-8601 timestamp (no
wip prefix) -> push -> on push failure, git pull --no-edit then retry.
Atomic from the user's view. Recorded as ADR-010. The previously-planned
v0.7 commit-message-prompt item is removed; it contradicts the
gct/timestamp model.
(2) Replace the v0.1 captive-portal first-run with build-time env-var
config: build.rs reads TW_* env vars and embeds them as constants. No
NVS read, no LittleFS mount, no AP mode, no HTTP server. The v0.1
target user is the dev themselves; the first release usable by non-dev
users is v0.9, and the v0.9 settings entry is reframed accordingly.
ADR-005 updated to describe the build-time path and the v0.9 migration.
The two changes share files because the v0.1 spec is one interlocked
document; splitting further would require line-level surgery without
improving auditability.
CONTEXT.md fixes the project's user-facing vocabulary (Tracked, Local,
Save, Publish) and the principles that fall out of those definitions
(the device is a writing tool, not a sync engine; it does no git work
the user did not explicitly request). README's file-scopes section and
repo-layout listing point at the new glossary so a first-time reader
lands on canonical definitions, and the ADR log carries an inbound link
so future ADRs can rely on the same terms.
The original row collapsed C and C++ together, but they trade differently
on the ESP-IDF target (RAII, generics, binary size, exception story). Split
them so the language-and-runtime decision actually reflects what was
considered.
Adds inline pointers from ADR-007 (storage) to the v0.1 technical
persistence + file-layout sections, from ADR-008 (power) to the v0.1
out-of-scope and roadmap v0.8, and from ADR-009 (keyboard) to spike 4
in the v0.1 technical bring-up order.
Adds a "Related docs" header at the top of adr.md and inline "See also"
pointers from ADR-001 (binary/build tradeoffs → qfd §7) and ADR-002
(render module → v0.1 technical, top H1/H2 functions → qfd §3). Makes
the design-doc set walkable instead of a flat list.
Prior text said "~40 KB of stack space"; the v0.1 technical design's
task table sums to 76 KB (usb 8 + wifi 8 + ui 16 + render 12 + git 32).
Also widens the std::thread stack-cost note from a flat 8 KB to 8–32 KB
to match the per-task budget. No design change — 76 KB still fits
comfortably in the ESP32-S3's 512 KB internal SRAM.
