chore: v2.7.4

[angeloINTJ]

What

SIMUT_VERSION 2.7.3 → 2.7.4. Everything that names the current release catches up:

• the CHANGELOG, in English and Portuguese;
• the three READMEs;
• both user manuals and the docs index;
• the landing page, in its three languages;
• the product manual: chapters 1, 3, 4, 5, 6, 8, 9, 13, 14, 26, 28 and 30, and appendix C, regenerated.

What v2.7.4 ships

Change	PRs
A sensor scan no longer breaks a hardware-I2C BMP280	#175
Four settings nothing reads no longer restart the device	#182
The touch panel's routes and its Configuration section leave the alpha and the Air	#184, #190
Dead code removed	#181
The build configurator	#185–#188
Feature-model groundwork	#168–#174, #180

What the manuals gain

• Chapter 5.
  • The configuration groups: logging and display_pin have no field left, and sensing is only the DS18B20 resolution.
  • Amostra (ms) and Registro Local save without a restart.
  • The Touch Calibration section is on the release only.
  • The page has seven sections, not six: the list had missed v2.7.3's Restart section.
• Chapter 6. The sample interval's restart column. The scan hands the hardware-I2C pins back. GP16 still does not come back, so the advice to restart after a scan stays.
• Chapter 26.
  • The alpha and the Air have 54 routes, not 56. On the bench, the eight panel and TLS routes answer 404 without a session, like an unknown path.
  • The panel-only rows are marked.
  • logging and display_pin leave the restart classes.
• Chapter 3. A new section on the build configurator.
• Chapter 30. The row about the touch reset on an alpha now says the section is not there.

Stale before this release, fixed here

• Landing page. The third release card still said On main — next release about v2.7.2's Air clock and telemetry batches. It is gone, and a v2.7.4 card leads.
• READMEs.
  • They said the alpha's 16×2 LCD had never been on glass. It was, today (below).
  • They counted 410 host test cases in 7 suites. CI runs 420 in 8.
  • The pt-BR and es-ES security sections said 61 routes, 51 gated. check_authz.py counts 62 and 52.
• ConfigApply.h. Four enum comments described fields that chore: P0 stop four dead config fields from forcing a needless reboot #182 moved out: CFG_NET still said HTTPS, CFG_SENSING still named the cadence, and CFG_LOGGING and CFG_PIN have no field left. The fix touches comments only, on the same number of lines: the release and alpha .uf2 built before and after are byte-identical (afa40005, ceda033a).
• flash_budget.json. chore: P0 remove dead code — unregistered staging selftest + unreachable stats screen #181 and feat: P2 routes seam — /api/themes and /api/reset_touch_cal register TFT-only #184 moved measured without moving measured_at_commit, which still described fix: a sensor scan no longer breaks a hardware-I2C BMP280/BME280 #175.

Flash

All six images were built locally at this commit, and each is within its budget.

env	used	margin to budget
release	997,980	2,592
test	1,003,380	2,592
test_https	1,011,036	2,592
asserts	1,000,156	2,592
alpha	963,308	2,920
air	1,003,144	2,960

• measured moves for test only: +8, from fix: the touch-calibration section only on images with a touch panel #190 re-stamping the pages.
• Budgets are unchanged.
• Against the published v2.7.3 .bin: the release is 240 B smaller, and the alpha and the Air are the same size to the byte.
• The configurator's base sizes (feature_costs.json) are these same figures.

Bench

The release candidate was built from main before #190.

image	what was checked
test	web suite 87/0, the console modes, five sensors, a scan with the BMP280 still reading 90 s later, the rehearsed commit, both touch-panel routes, the panel captured
release	the same checks, then 10 min with no restart
Air, alpha	boot, five sensors
release, with the 2.7.4 version string	flashed: the console and the login page say 2.7.4
alpha, on an HD44780 16×2 wired in parallel	the maintainer confirmed on the glass: the boot screen with the version and the progress bar, the connected screen with the IP, and the sensor carousel with the slot and the Wi-Fi level
#190's alpha image	/config 11/11

Found on the bench and pre-existing: #189 (a chunked reply occasionally loses its framing; v2.7.3 does the same). It is listed under Known.

Gates run locally

• The gates: scan_secrets, gen_logcodes --check, check_authz, check_license, check_angulo, check_fsguard, check_air_consistency, gen_features --check, check_features, check_feature_sprawl, test_configurator_rules, test_build_custom, test_configurator_page, test_webui_feature_routes, test_h5_day_merge.
• build_manual --check: 1,732 internal links, none broken.
• The eight native suites: 420 cases.
• The landing page's scripts parse, and every data-i18n key has a pt and an es entry.

After merge

1. gh release create v2.7.4 --target main.
2. release-ota.yml builds and attaches the images.
3. verify_release.py: first against v2.7.3, as a negative control that must mismatch, then against v2.7.4.
4. Flash the published .uf2 on the bench.
