reuse-surface = capability registry at /home/worsch/reuse-surface (helix_forge):
Markdown entries via templates/capability-entry.template.md, D/A/C/R maturity
vectors, reuse-surface CLI (validate/query/export/overlaps), hub at
reuse.coulomb.social. T1 now registers shard-wiki's capabilities as registry
entries; T3 contributes gaps back via REUSE-WP/agent message; T5 evaluates
reusing sibling feature-control for per-shard activation.

The 56af8185 workstream still exists in the DB (finished); clearing the id only
unlinked it (slug taken, cannot recreate). Restoring re-links the file.

WP-0009 git-backed DecisionLog + per-space append authority (keystone backing);
WP-0010 derived views (wikilinks, BackLinks, RecentChanges, AllPages/SiteMap);
WP-0011 incremental union + equivalence index + I-2 verification;
WP-0012 second adapter (git-IS-store) validating the contract on a new substrate.

edit()/overlay()/apply_overlay() on InformationSpace. edit() unifies the write
path through one principled route — draft overlay then apply: write-through-capable
target fast-forwards (APPLIED), read-only target keeps the draft as local truth
(KEPT_DRAFT), external drift refuses (no clobber). Integration tests cover all
four. 64 tests green, pyflakes clean. Flips WP-0008 done.

resolve() layers open overlays onto canonical pages (overlay_state=DRAFT always
surfaced; overlaid body projected when policy.show_drafts); draft-only edits make
a not-yet-existing page resolvable. Never hides an unapplied overlay (I-4). Policy
gains show_drafts. 4 tests green, pyflakes clean.

Overlay value type (id, target, base_rev, body, state) recorded as an
OVERLAY_CREATED decision-log event (coordination-canonical); get()/open_overlays()
reconstruct from the fold. 4 tests green, pyflakes clean. (ADR-05, blueprint §8.2)

FolderAdapter(writable=True) declares WRITE+PER_PAGE, implements write() and
current_rev() (mtime token for drift detection). Conformance gains a
content-preserving positive write probe for WRITE-claiming adapters. 5 tests
green, full suite green, pyflakes clean.

InformationSpace ties the slice together: conformance-gated attach → resolve →
read, with alias() recording coordination decisions in the log. Exposed from the
package root. End-to-end integration test (two folder shards → union read with
layered provenance + chorus + alias redirect + red-link + nonconformant-rejected).
pyflakes clean, 39 tests green. Flips WP-0007 done.

Versioned ShardAdapter ABC (shard_id/profile/keys/read mandatory; optional verbs
raise NotSupported by default = honest absence). FolderAdapter reads a dir of
Markdown into Pages (relpath=key, mtime=source_rev, provenance envelope),
declaring a validated read-only file-store profile. 4 tests green.

Identity = stable shard-scoped handle (not a fingerprint); Placement separate;
Span carries a layered provenance delta. Page model (PageShape incl. the four
computational shapes). CapabilityProfile with orthogonal-core axes + validate()
applying §6.5 implication rules that reject impossible profiles. Imports only
provenance/. 8 tests green.

Decision records for the 10 federation topics + the federation-model taxonomy,
each with a Decided/Deferred/Open footer: star orchestrator positioning, remix
primitives (overlay-default), identity/placement/equivalence + chorus,
event-sourced coordination journal + per-space append authority, server-primary
incremental union, notify-driven freshness, space lifecycle, reference-not-copy
transclusion, detection-core/resolution-policy preset catalog, the federation-
ops capability matrix, and the six selectable/composable federation models.

Fixes B-4. Incremental delta is not additive: a change processes bucket
exits (retract unsupported edges) + entries (add) + propagation across
equivalence neighbours, not just new candidates. Adds an I-2 verification
mechanism: per-partition Merkle-style digest + background consistency-checker
vs sampled fold → scoped self-healing recompute on drift. I-2 now
eventually-verified, not asserted.

Fixes B-2. Capability profiles are verified, not self-asserted: the contract
ships a versioned conformance suite that exercises each declared verb/position
against observed behaviour; passing is an admissibility precondition (lying
profiles rejected at registration); mismatch reported as a capability diff.
Makes I-3 / §6.5 sound rather than aspirational.

Resolves B-1+B-3. Coordination-canonical state = an append-only decision log
in the git journal (events: overlay/binding/alias/merge); queryable current
state = a derived fold (tier-3, indexed). Concurrency: one append authority
per space (lease/leader) → totally-ordered per-space log, read-your-writes
across instances, HA via re-grantable lease, partition yields to log integrity.
Updates §1, §4, §8.1, §8.6, §11. I-6 strengthened (coordination state is now
git-addressable history/patch/review), not bypassed.

Records the round-2 critical review (history/260615-...-review-2) and
establishes SHARD-WP-0006 to: reconcile overview with hardened body (§A),
settle the journal/coordination-state model (event-sourced decision log;
single-vs-multi-writer concurrency — B-1+B-3), require an adapter conformance
suite (B-2), fix incremental-equivalence correctness + I-2 verification (B-4),
and track §C as O-8..O-11.

Fixes B-3/C-3. §9.1 structural per-tenant partitioning of the derived tier
(no shared cross-tenant cache; read-time filtering as defence-in-depth;
reconciles I-2+L5 per partition); new invariant I-13. §8.1 history stays
recoverable AND bounded (gc/repack, squash-compaction of churn preserving
recoverable endpoints, per-shard offload, anti-abuse hooks).
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Fixes D-2/D-3/D-4. §7.3 effective-vs-own provenance (page envelope + span
deltas, near-zero per-span cost). §8.4 projection trivial-by-default
(plain lazy replication), derivation/liveness/view-registry as extension
points only for the computational/typed tail. §11 adds policy/ + provenance/
as dependency-free leaf rails (mechanism never in a rail), tightened import rules.

Fixes D-1. ~6 independent core axes (substrate, write-granularity, opacity,
envelope, access, liveness) with the rest implied via published rules that
forbid impossible profiles; a small named axis-interaction table is the
degradation contract (proof obligation behind 'core logic written once').
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Fixes C-1/C-2. Incremental change-driven maintenance (notify->delta) is
primary; full rebuild is a rare, envelope-respecting, concurrent fallback
(not required cheap). Equivalence via blocking/LSH candidate-gen + verify +
incremental maintenance, replacing O(N^2). Index is derived, per-tenant.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Fixes bug B-2. States the guarantee (read-your-writes for journal-owned
coordination-canonical state; causal across the derived tier; eventual+
freshness-labelled for sharded inputs). Conflict detection+representation =
core mechanism, resolution = policy. Overlay-apply-under-drift semantics
(fast-forward / three-way / refuse+re-present) and journal ordering.
