Documentation only. Ready for dispatch after these four repairs.
Replaces pin 5 and t7. The earlier draft required undo to distinguish "never
authored" from "authored to the default", which PLAN_GENESIS_OPS.md section 5
trap 5 explicitly withdrew - and SetMetadata is the disproof: Score::empty
seeds metadata exactly as it seeds tuning_context, and base ingest runs
metadata_chain.seed precisely so a value-restoring undo of the first
operational write restores the pre-operational state. Undo restores the seeded
base settings, default or not, and the distinction must stay UNOBSERVABLE -
code that can tell the two apart is a defect, not a safeguard. Predecessor::Base
vs ::Write earns its keep only for the bookkeeping families, where a base
predecessor returns a map key to absence; ScoreTuningContext is always-valued
like metadata and has no absent state to return to. t7 now asserts the two
cases are indistinguishable rather than that they differ.
Appends epoch 10 to the authoritative ladder with G2b as the event. It stays
monotonic and prefix-closed, and it is the first exercise of the ladder's own
growth path - G-minor's wildcard-free introduced_minor means kind 34 cannot
compile without one.
Adds the explicit non-goal the plan requires: G2b authorizes no pruning or
compaction of the canonical operation log. The rung sharpens that prohibition
rather than relaxing it, because after G2b pruning would discard authored
genesis state rather than merely re-derivable state.
Adds the touch table the gate already referred to but which did not exist,
derived from G2a's actual thirty-file footprint plus G1's one extra rather than
from recollection: the new core type and its export, full ops plumbing
including envdecode/migrate/v0/valuegen/fuzz/vectors, the bundle accept-set
raise and its falsified rationale, the four budgeted boundary crossings, text
projection with companion 0.11.0, all four .tex sources with all four PDFs, both
vector corpora, and P13-S13's closure.
Ratifications folded in: subset design, epiphany_core::TuningContextSettings,
epoch 10.
