remediation: backfill v0.1.0/v0.2.0 gaps (P0+P1)

- vault: add vault-get-secret/vault-set-secret wrappers
- programming-org: implement org-modify (text search-replace) and org-ast-render (AST to Org text)
- programming-literate: implement literate-block-balance-check (paren validation) and literate-tangle-sync-check (org→lisp diff)
- system-self-improve: replace stubs with surgical text editing and error diagnosis; remove dead first defskill
- system-event-orchestrator: implement orchestrator-bootstrap (scan Org files for HOOK/CRON)
- system-archivist: implement Scribe distillation (daily logs→atomic notes) and Gardener link/orphan repair
- system-memory: implement memory-inspect with type/todo/orphan statistics
- core-skills, core-context: fix path relic (skills/ → lisp/, org/)
- docs: add Token Economics section to DESIGN_DECISIONS, remediation roadmap entries

 ** Tasks
 
+*** Remediation: Backfill v0.1.0/v0.2.0 Gaps
+
+These features were marked DONE in prior versions but are stubs, no-ops, or
+missing. They must be completed before v0.3.0 feature work proceeds.
+
+**** TODO P0: Add vault-get-secret / vault-set-secret wrappers :backfill:
+:PROPERTIES:
+:ID:       id-vault-secret-wrappers
+:CREATED:  [2026-05-03 Sun]
+:END:
+=vault-get-secret= and =vault-set-secret= are exported from =core-defpackage=
+and called from =gateway-manager.org= (lines 36, 86, 180) but never defined.
+=gateway-link= crashes at runtime. Add one-line wrappers in =security-vault.org=
+that delegate to the existing =vault-get=/=vault-set= with ~:type :secret~.
+
+**** TODO P0: system-archivist — Scribe + Gardener :backfill:
+:PROPERTIES:
+:ID:       id-archivist-distillation
+:CREATED:  [2026-05-03 Sun]
+:END:
+Scribe: distill daily Org logs into atomic Zettelkasten notes with backlinks.
+Gardener: scan for broken =[[file:]]= links and orphaned =memory-object= entries.
+Wire both as cron jobs via =system-event-orchestrator=.
+Depends on: orchestrator bootstrap (P1 item below).
+
+**** TODO P0: system-self-improve — surgical edit + error fix :backfill:
+:PROPERTIES:
+:ID:       id-self-improve-real
+:CREATED:  [2026-05-03 Sun]
+:END:
+= self-improve-edit=: =org-read-file= → text replace → =snapshot-memory= →
+=org-write-file= → =literate-block-balance-check= → tangle → reload.
+=self-improve-fix=: parse error log → =lisp-structural-check= →
+=lisp-extract= → surgical repair → =repl-eval= verify.
+Remove the dead first =defskill= registration (trigger nil, overwritten by second).
+Depends on: =programming-org=, =programming-literate= (P0 items below).
+
+**** TODO P0: programming-org — fix org-modify + org-ast-render :backfill:
+:PROPERTIES:
+:ID:       id-org-modify-render
+:CREATED:  [2026-05-03 Sun]
+:END:
+=org-modify(filepath, id, changes)= ignores ~changes~ and only logs. Should locate
+node by ID in file and apply changes to its content.
+=org-ast-render(ast)= returns a hardcoded placeholder. Should convert plist AST
+back to Org text.
+
+**** TODO P0: programming-literate — fix both stubs :backfill:
+:PROPERTIES:
+:ID:       id-literate-real
+:CREATED:  [2026-05-03 Sun]
+:END:
+=literate-block-balance-check=: verify all =#+begin_src lisp= blocks in an Org file
+have balanced parentheses. Returns T if all balanced, error message otherwise.
+=literate-tangle-sync-check=: verify =.lisp= file matches tangled output of =.org= file.
+
+**** TODO P1: system-event-orchestrator — bootstrap implementation :backfill:
+:PROPERTIES:
+:ID:       id-orchestrator-bootstrap
+:CREATED:  [2026-05-03 Sun]
+:END:
+=orchestrator-bootstrap= currently only logs. Should scan Org files for =#+HOOK:=
+and =#+CRON:= properties and register them via the existing registries.
+Prerequisite for archivist cron jobs.
+
+**** TODO P1: system-memory — memory introspection :backfill:
+:PROPERTIES:
+:ID:       id-memory-inspect
+:CREATED:  [2026-05-03 Sun]
+:END:
+=memory-inspect= only logs. Should return structured statistics: object count
+by type, TODO state distribution, orphan count, snapshot list. Trigger on
+=:INTROSPECTION= sensor type.
+
+**** TODO P1: Path relic — skills/ → lisp/ in skill-initialize-all :backfill:
+:PROPERTIES:
+:ID:       id-path-relic
+:CREATED:  [2026-05-03 Sun]
+:END:
+=skill-initialize-all= and =context-skill-source= resolve against =skills/=
+under =$PASSEPARTOUT_DATA_DIR=. Core and skills were merged into =lisp/=.
+Update both functions to point at =lisp/=.
+
+**** TODO P2: core-context — semantic retrieval (embeddings) :backfill:
+:PROPERTIES:
+:ID:       id-embeddings
+:CREATED:  [2026-05-03 Sun]
+:END:
+=org-object-vector= is never populated; all similarities are 0.0. Generate
+embeddings via Ollama =nomic-embed-text= at ingest time. Store in
+=memory-object.vector=. Fallback: TF-IDF bag-of-words.
+
+**** TODO P2: core-context — subtree-based skill source loading :backfill:
+:PROPERTIES:
+:ID:       id-skill-subtree
+:CREATED:  [2026-05-03 Sun]
+:END:
+=context-skill-source= reads entire Org files. Add =context-skill-subtree=
+for targeted retrieval of specific function docs or test blocks by heading name.
+
+**** TODO P3: Variable name drift normalization (out of scope for now) :backfill:
+:PROPERTIES:
+:ID:       id-name-normalization
+:CREATED:  [2026-05-03 Sun]
+:END:
+=*memory*= (context) vs =*memory-store*= (memory). =*skills-registry*= with
+underscore (reason/context) vs =*skill-registry*= with hyphen (defpackage).
+Normalization pass across all modules. Touches every file — do after P0-P2
+are stable. Do not mix with functional changes.
