The project ships as peltier.io; "hotpath" was the placeholder working name
(CLAUDE.md: "Rename freely; nothing depends on it"). Replaces the product
name in the README front page and every mdBook source chapter — book title,
nav header, and prose ("Peltier profiles…", "Peltier sells…") — plus the
theme CSS comment.
The metaphor is unchanged (a Peltier device is a thermoelectric cooler:
"spot cooling for hot paths"), and the literal noun phrase "hot paths"
stays. Two code identifiers are intentionally left as-is because they are
not prose: the `agent/hotpath_agent/` Python module path and the
`HOTPATH_ISOLATION` env var — renaming those is a code change, not a docs
one.

Phase 5 write-up for the two SPEC §13 forks now that both are built:
- results/phase5/README.md — the full argument for each fork, with the
kernel-lane demo and learned-policy ranking tables and reproduce commands.
- results/phase5/learned-policy.txt — captured `cargo run -p policy` output
over the 34-row ledger.
- docs/src/research-forks.md — new mdBook chapter, wired into SUMMARY.md.
- docs/src/roadmap.md — Phase 5 row added; the Frontier section rewritten
from "out of scope" to "built, both routed to human review", with the
honest note that the actual GPU run needs GPU hardware absent here.
- CLAUDE.md — Phase 5 COMPLETE status paragraph.
No trust-layer or gate change; this is documentation of work already
committed (learned policy b7297ad, kernel lane 5abeb60).

- docs/: an mdBook documentation site — thesis, architecture, measurement
discipline, equivalence gates, agent loop, isolation/anti-reward-hacking,
playbook, ROI, reproduce, roadmap, and the five case studies (pulled from
their single source in results/ via {{#include}}). Builds clean (21
pages).
- .github/workflows/docs.yml: builds mdBook and deploys to GitHub Pages on
push to main (one-time setup: Settings → Pages → Source = GitHub Actions).
- README.md: rewritten as the project front page — the thesis, the verified
results table, layout, quick start, how it stays honest, links to the
book. Replaces the stale Phase-0-era text.

harnessd gains --socket mode (Unix socket, trusted uid, mutating ops
serialized); the harness client speaks socket when
HOTPATH_HARNESS_SOCKET is set. scripts/agent-isolated.sh launches an
attempt with the agent tree confined — mountns mode (repo bind-mounted
read-only, CAP_SYS_ADMIN/CAP_SYS_PTRACE dropped; no credential copying)
or user mode (unprivileged hpagent, bench-metal shape).
scripts/isolation-check.sh + just isolation-check verify the boundary
from the agent's side: 19 checks, both modes, all passing — repo
writes, forged ledger INSERTs, trust-binary replacement, rw remounts,
and userns re-entry all refused; the harnessd socket door works.

Closes the CI-reachable slice of the Phase 1 infra gaps:
- trust-layer job: cargo test + clippy -D warnings + fmt
- target-gates-no-net: fetches pinned targets (new targets/fetch.sh),
regenerates + verifies corpora, runs 'just gates tokei'
mechanically, and executes the bench workload inside a
--network=none container (SPEC 3.1/10 no-net requirement)
- runner-calibration (informational): A/A + injection harness measures
the shared runner's noise floor per run, evidence uploaded as an
artifact — environments are judged empirically, not assumed
- perf-probe (informational): reports which perf event sources work
docs/infra.md maps each remaining hardware requirement (pinned cores,
governor/SMT control, separate-uid trust layer) to the bench-metal
self-hosted runner setup a human can complete in ~15 min.
