Patches each link of the closed-loop chain (world-truth -> invariant -> dispatch -> worldDelta -> milestone) so the contract can no longer advance on a lie or stall on an unreachable milestone, and surfaces the result on the monitor. - Unblock M6_lighting: add gather.coal producer (mirrors gather.stone, strict expectGain), register it, add the skill-graph node, and make curriculum.shelter.torch two-step (gather coal -> craft torch). craft.torch needed coal but no skill produced it, so the contract pinned on M6 forever and starved M7/M8/M9. One curriculum edit fixes both rails. - M8 no longer falsely satisfied: build-shelter records locations.shelter only on real progress (setLocation moved below the no_progress guard). - M2_bed made monotonic: sleepInBed writes locations.bed when the bot places its own bed, so M2 stays met after the carried bed item is consumed. - Observability: new ink-free tui/format.js helper renders per-tick state / firing rail / active skill / blocked prerequisite / stall reason in the monitor header (fields bot.js already computes but never showed). - Harden the valid-skill-id guardrail: skillRegistryPrompt preserves the "NEVER invent" footer when truncating (a growing registry was dropping it), and fix the stale "tech-tree > autonomous" reflex chain in the escalation prompt. Tests: 494/494 passing; new build-shelter / invariants / format suites plus skill-graph, curriculum, skill-registry cases. lint-patch clean.
