engine/profile.py: engine_base_profile() (kernel-only c2-minimum profile),
ProfileContribution (an extension's ON_PROFILE contribution: axis raises + verbs),
derive_profile() folds active extensions' contributions onto the base in deterministic
order then validate() — so configuration->capability is one chain and composition can
never yield an impossible profile (encrypted+native-query rejected). 5 tests green,
96 total, pyflakes clean. Marks T4 done.

Records the accepted decision: shard-wiki's native engine uses feature-control via
OpenFeature for per-shard extension activation (availability only, never authz),
provider-pluggable with a LocalProvider standalone default (mirrors the identity
ladder), at the engine layer, consuming the mature feature-control.evaluate slice.
Adds spec/adr/ series + README; hub decision abf7830f recorded.

cross-links the engine as a canonical-mode shard (federation/union stay in the
orchestrator). reuse-surface engine capability promoted D2->D3 (4204255).

Headless, API-first, agent-optimized native engine = canonical-mode shard backend.
Thesis: a page-store kernel with a typed-extension runtime; everything beyond the
c2-minimum is a typed extension activated per shard, and the shard's §A capability
profile is DERIVED from its active extensions (configuration->capability->conformance).
9 engine invariants (engine-is-one-shard, small kernel, per-shard activation,
profile-from-extensions, headless/agent-first, reuse-not-reinvent, typed+verified).
Kernel (4 concepts), typed-extension model (typed hooks + deterministic composition +
feature-control activation), T2 featureset/conflict-mediation realized, engine-as-shard,
agent-first API surface, module sketch, reuse (consumes feature-control/authorization;
G1 framework proposal), traceability, decisions/open, stability note. Marks T5 done.

Registered capability.wiki.derived-views in reuse-surface (8 wiki.* total, index 20,
validate ok, pushed d985e68). Tracked contributions note (history/260615-...): proposes
two cross-cutting gaps to reuse-surface (G1 typed-extension-framework, G2
translation-fidelity) and records consumptions (feature-control.evaluate,
authorization.policy-evaluate). Sent to the reuse-surface agent via send_message. Marks T3 done.

Adds 'Capability structure for the wiki engine (reuse-surface-aligned)' to
UseCaseCatalog.md (no UC renumbered): a small always-on engine core (EC-1..EC-5),
ten typed per-shard-activatable extensions (X-OVERLAY/AUTHZ/VIEW/STRUCT/ADDR/COMP/
PROV/COLLAB/FED/ATT) each mapped to a reuse-surface capability with activation
defaults, and a conflict-mediation map turning conflicting requirements into
mechanisms. Bridges demand -> the engine typed-extension model (T5). Marks T2 done.

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.

unlinked it (slug taken, cannot recreate). Restoring re-links the file.

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

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.

provenance/. 8 tests green.
