entitled skills: altissimo + extended piccolissimo in the bundle (#907, ADR-0011 home)

[aarontrowbridge]

What changed after the first commit (the ADR-0011 correction)

The first commit on this branch added a staging-script mechanism sourcing skills from amicissimo/skills/ — built on the premise (from amicissimo #403) that piccolissimo/intonatissimo were "staging-local with no canonical home". That premise was wrong, and the branch is reworked:

• ADR-0011 (docs/adr/0011-entitled-skill-surface.md, accepted 2026-08-27) ruled this exact question: entitled skills live in packages/extension/skills/, ship in the vsix, and gate at staging — "entitled is a STAGING gate, not a location". The bundle is the single source of truth, "not an extract pipeline". Hash-verified: the pre-change staged copies were byte-identical to the bundle copies — the boot rsync staged them all along.
• amicissimo The studio manifest: config.toml binds the installation (#402) #404 (the skills/ canonical home) was reverted (amicissimo Literature plane slice 1: the paper record + the unified corpus fold #405/feat(github-app): validator for Connections panel (#403) #406, main e9a6922).
• The staging-script mechanism is dropped (reverted in this branch's second commit) — the boot flow already stages bundle skills; a second source would be a second master.

What this PR now delivers

The content, in its correct home, policy-trimmed:

File	Change
packages/extension/skills/altissimo/SKILL.md	NEW — the measured Altissimo tuning doctrine: ρ-schedule table (default ladder / caps starve / :demand with its honest MIXED real-problem verdict), the churn signature, the AL-entry warm-start laws, what-binds facts, honest arm-comparison rules. Trimmed to usage per ADR-0011 (no fleet doctrine, no vault pointers, no internal roadmap).
packages/extension/skills/piccolissimo/SKILL.md	Extended: matrix-free density routing (4.2×, assert-don't-assume, bang-bang plateau), the two upstream density-path bugs (Piccolo #337 √γ-prescaling, #338 EqualityConstraints endpoint pins), set_state_guess! state warm-starts, the ECO constructor section (envelope + F_pro≠F_avg traps), the measured Magnus caveat, smoke-budget honesty rail.
ops/README.md	staging floor 45 → 46.

Content-policy note for review

Both skills carry surface: entitled, entitlement: issmo (the exact pattern of the already-shipping piccolissimo skill). Reviewed per ADR-0011's per-line test: constructors, kwargs, knob facts, idioms, measured usage guidance ship; internal trait names, threaded-site architecture detail, fleet compute doctrine, and vault pointers stay in the internal tier (already in the armonissima commons + vault cards). The team-internal deep doctrine (falsified-probe narratives, Prestissimo carry-overs, measurement discipline) is NOT in this PR — it rides the armonissima commons updates.

Verification

• Frontmatter mirrors the shipping piccolissimo pattern (leak-guard admits public+entitled).
• The trimmed content is live in the server staging tree (hand-rsynced = what the boot rsync delivers post-merge); the three prior amicissimo-sourced copies were replaced by these trimmed ones.
