…26-04-28) Three structural fixes for the PR #23 mise+bun-1.3.13 502 transient class, addressing Aaron 2026-04-28 directives: "is there not a way to fix this?" (don't default to rerun) "we want to use stock and we better not be using that old version of ubuntu" "can you cache and retry?" "we want to make sure dev seutp and build machine setup are as close to the same a possible" "why not cache the whole install/setup" 1. **Comprehensive install cache** on lint-shell, lint-workflows, lint-markdown jobs (previously uncached). Caches everything tools/setup/install.sh writes: ~/.local/bin/mise (the mise binary) ~/.local/share/mise (mise runtimes — bun/dotnet/python/uv/java) ~/.cache/mise (mise download cache) ~/.dotnet/tools (dotnet global tools) ~/.elan (Lean toolchain) ~/.config/zeta (managed shellenv) tools/tla, tools/alloy (verifier jars) Cache key hashes BOTH .mise.toml AND tools/setup/** so install logic changes invalidate cache → vanilla install path gets re-tested whenever discipline changes. 2. **Retry layer** on the install step (CI-only — dev runs stay interactive). Three attempts with 10s/30s backoff. Mise's internal 3-attempt retry was exhausted on PR #23's bun download; wrapping at the install.sh layer catches the case where mise itself gives up. Same shape across all 3 lint jobs. 3. **Ubuntu 24.04 bump** on every workflow that pinned ubuntu-22.04 (gate.yml lint jobs ×6, resume-diff.yml, scorecard.yml, memory-index-duplicate-lint.yml, budget-snapshot-cadence.yml). ubuntu-latest = ubuntu-24.04 since Jan 2025 per Otto-247 WebSearch verification; 22.04 is now LTS-2 stale. Stays on stock GitHub- hosted runner image (no custom pre-installed bun) per Aaron's "we want to use stock" + "vanilla ubuntu so we test do our install scripts work on vanalla and deve machines." Dev↔CI parity: install.sh runs on both surfaces; cache restores state similar to a dev's already-bootstrapped local env; cache key on tools/setup/** + .mise.toml matches what a dev's environment depends on. install.sh stays idempotent so cache hit = fast no-op, cache miss = full vanilla install (which is the install-script validation Aaron wants). Composes with PR #75 curl_fetch helper (downstream curl retries), PR #76 + #79 markdownlint carve-outs (verbatim ferry preservation), Otto-247 version-currency, Otto-235 4-shell portability, Otto-341 mechanism-over-vigilance, and `feedback_structural_fix_beats_process_discipline_velocity_multiplier_aaron_2026_04_28.md`.

This cache entry includes tools/tla and tools/alloy, which are not just tool outputs—they also contain tracked repo sources (for example specs/*.tla and AlloyRunner.java). Since the key only hashes .mise.toml, tools/setup/**, and global.json, a PR that edits files under those directories (without changing setup files) can have its checked-out files overwritten by a restored cache before lint executes, causing CI to analyze stale content. Cache only the downloaded jar targets (for example tools/tla/tla2tools.jar and tools/alloy/alloy.jar) or expand the key to include those tracked directories’ contents.

…Otto-357 strengthen (#83) * tick-history: 2026-04-28T05:44Z — PR #80 MERGED + #81 retry-bump + #82 Otto-357 strengthen + 3 conflict resolutions * fix(pr-83): reconcile verify-don't-parrot streak count — 4 ticks running (was inconsistent 3 vs 4) PR #83 review thread (P2 copilot): the row described the streak count as both "3 ticks running" early and "4 ticks running" later. The conflict was a scope mismatch — the early count was meant to be cumulative ticks-of-discipline-applied (4, matching the observations enumeration), but I'd written it as 3 from an older draft state. Reconciled to a single 4-count framing that explicitly references the observations column (which enumerates the 4 distinct verifications applied this tick: cron-id verify / AUTONOMOUS-LOOP.md grep / CronList freshness / retry-3-failed-on-#23 sourcing).

Summary
Three structural fixes for the PR #23
mise+bun-1.3.13 502transient class, addressing Aaron 2026-04-28 directives in sequence.What changed
1. Comprehensive install cache (lint jobs)
lint-shell,lint-workflows,lint-markdownpreviously had NO cache step (unlikebuild-testat line 156+). Now all three cache everythingtools/setup/install.shwrites:Cache key:
install-${runner.os}-${runner.arch}-${hashFiles('.mise.toml', 'tools/setup/**', 'global.json')}. Hashes BOTH .mise.toml (runtime versions) AND tools/setup/** (install logic itself) so changes to either invalidate cache → vanilla install path re-tested whenever discipline changes.2. Retry layer (install step)
3-attempt retry with 10s/30s backoff. CI-only (dev runs stay interactive — user decides). Mise's internal 3-attempt retry was exhausted on PR #23's bun-1.3.13 download; wrapping at the install.sh layer catches the case where mise itself gives up.
3. Ubuntu 24.04 bump
Per Otto-247 WebSearch verification (April 2026):
ubuntu-latest=ubuntu-24.04since Jan 2025 rollout.ubuntu-22.04is now LTS-2 stale.Bumped:
gate.yml(×6 lint jobs),resume-diff.yml,scorecard.yml,memory-index-duplicate-lint.yml,budget-snapshot-cadence.yml. Stays on stock GitHub-hosted runner image — no custom pre-installed bun — preserving Aaron's "vanilla ubuntu so we test do our install scripts work on vanalla and deve machines."Dev ↔ CI parity
