The H10-H15 mild conflict node still pointed at C-10-15 (H15's
pre-retirement column). H14's removal renumbered H15 to column 14,
so the roof coordinate becomes C-10-14. Missed in the earlier
sweep — comment line already says "H10-H15" so the intent was
unchanged, only the cell coord was stale.
The doc previously conflated functions (transformations the device
performs) with characteristics (measurable attributes). Surfacing
Functions as their own ontology layer makes HOW names — which pack
a function reference plus an attribute — readable without function
definitions staying implicit.
- new GLOSSARY.md at root: 5-layer ontology stack (WHAT / Function /
Characteristic / Metric+Unit / Target), peer to CONTEXT.md
(device-specific vocabulary)
- qfd.md §2 opens with a Functions inventory (Type, Save, Publish,
Recover, Boot, Provision); Render and Reconnect noted as
sub-functions; Provision flagged as build-time-only in v0.1
- H1 "Keypress → glyph latency" → "Type latency (keypress → glyph)"
- H4 "Cold boot → cursor ready" → "Boot latency (cold)"
(the arrow transformation moves to the Functions inventory; the
parenthetical keeps the residual qualifier)
- cascade through §3 priority list, §6 critical-performance-budget
rows for H1/H4, §8 inconsistencies, and quality-house.md TikZ
column labels
Matrix cell strengths held; no Σ recompute.
Module count / public-API surface is a static source-code property,
not a runtime function nor an artifact characteristic like H10 binary
or H15 build time. It was a refactor-leverage proxy for W9 — proxies
of proxies belong in the ADRs and the component matrix, not in the
HoQ. Removed from §2, §5 matrix, §4 conflict list, and the C12
overloaded-list mention; basement Σ total drops 1674 → 1557 so rel%
recomputed in quality-house.md.
Captures "I can carry the device and write away from a desk" as a
distinct WHAT from W11 (multi-day battery), weight 8. Recomputed
basement Σ (1546→1674); H8 climbs #6→#3 in the §3 priority list as
its voter base widens to include W14, and H12 enters the top six at
#4. §6's "(b) narrow voter base" override for H8 is retired and a new
§7 ADR-008 vs W11+W14 unresolved-conflict bullet records that wall
power in v0.1 now disappoints two WHATs, not one.
reMarkable 2 with Type Folio tested less responsive than Freewrite Smart
Typewriter (Sailfish). With Smart at 3, reMarkable drops one notch to 2.
Total: reMarkable 42 → 41, now tied with Smart at 41.
Sailfish ships on Smart Typewriter Gen 3 as well as Traveler, so the
same firmware-driven bumps apply: W1 2→3 (Smart still trails Traveler
by one notch on panel size), W5 3→4, W9 1→2. Smart total 38 → 41.
Project gets a proper name. Replaces "Ours" / "Our product" placeholders
in the QFD perception zone and the working title "typewriter" in
README/CONTEXT headers and the npm name. "Typewriter" the category
noun (the writing-machine concept) stays unchanged — Typoena is the
brand, typewriter is the category. SoftAP SSID typewriter-setup and the
repo directory are deliberately left as-is.
The Sailfish firmware (2025-11-19) rewrote the Freewrite Traveler OS in
Rust, cut keystroke latency 40–100 %, and trimmed power draw -30 %
typing / -50 % idle. Three rows are bumped: W1 3→4, W5 3→4, W9 1→2.
Freewrite now ties reMarkable at 42; Pomera still #2 at 45.
text width={\qfdWhatW - 0.2}cm doesn't parse — the braces don't
evaluate the arithmetic, so TikZ sees "4.6 - 0.2cm" which isn't a
valid dimension. Pre-compute the narrower width with
\pgfmathsetmacro and reference the resulting macro instead.
Text box anchored at qfdLeftEdge + 0.1 with width qfdWhatW overflowed
0.1 cm past the cell's right edge into the Weight column, clipping
trailing words like "the", "lag,", "hob-". Shrink the box by 0.2 cm
so it has 0.1 cm clearance on both sides.
Each product now gets a profile line across all WHATs using the same
colour and dash pattern its legend entry already advertises, so the
shape of each competitor's strengths/weaknesses is readable at a glance
instead of having to mentally connect the dots.
Raise the header zone (qfdHdrH 3.2 → 4.2) so rotated HOW labels stop
crossing into the roof diamond grid, and wrap the perception title onto
two lines via text width so it stays inside its zone instead of bleeding
left over the H14/H15 column labels.
Drop the duplicated 13x15 strength matrix and 15x15 roof tables from
qfd.md; the same data already lives in quality-house.md's TikZ source.
qfd.md §3/§4 keep the narrative reading (priority list, conflict list)
and point to quality-house.md for the cells and basement sums. Both
files' regenerate/maintenance notes flipped to reflect the new contract.
Renders qfd.md §1-§4 as a classical House of Quality with 13 WHATs x 15
HOWs, roof correlations, and a perception zone scoring reMarkable 2,
Freewrite Traveler, and Pomera DM250 against the v0.1 target. Scores are
guessed, not measured; rationale and caveats are in the doc.
