Replace the TODO(lean-port) sorry with a complete proof of the
projectionOrdering theorem: for positive SourceValue pairs s1 < s2
with s2 ≤ maxExpected, projectToCoding preserves strict ordering
of the Q0_64 values.
The proof uses Nat-only arithmetic (no Float) and handles two cases:
- a2 < d: both values fit in Q0_64 range, ordering follows from
monotonicity of integer division
- a2 = d: a2*s/d = s clamped to q0_64MaxRaw; a1*s/d < q0_64MaxRaw
via the key inequality (d-1)*s < (s-1)*d

This squashes all local history (768 commits) onto the scrubbed PR #90
baseline. Individual commits were lost during filter-repo corruption;
the working tree content is preserved intact.

* fix(security): remove hardcoded secrets, patch command injection, tighten CORS and Cypher guard
- run_import_workflow.py, run_multi_import.py: replace hardcoded budget
password with BUDGET_PASSWORD env-var (fail-fast if unset)
- server.js /ingest: replace shell-interpolated exec() with execFile()
so user-controlled title/body cannot inject shell commands
- authentik-values.yaml: blank out bootstrap_password and bootstrap_token
so they must be supplied at deploy time via --set or sealed-secret
- cluster-dashboard main.py: restrict CORS from allow_origins=["*"] to
env-configurable whitelist (default: dashboard.researchstack.info),
methods to GET, headers to Authorization+Content-Type
- neo4j_obsidian_connector_router.js (both copies): replace permissive
prefix-only readOnly regex with a deny-list that blocks
CREATE/MERGE/DELETE/DETACH/SET/REMOVE/DROP anywhere in the query, and
route readOnly queries through session.readTransaction()

* fix(security): add CALL procedure allowlist for Cypher readOnly, add OPTIONS to CORS
- Cypher guard: restore positive allowlist for CALL targets (only db.* and
apoc.meta.* allowed in readOnly mode). Extract cypherReadOnlyViolation()
helper for clarity. Both copies updated.
- CORS: add OPTIONS to allow_methods so preflight requests succeed.

* fix(security): use negative lookahead for CALL allowlist, remove dead CALL\s*\{ branch
- Replace two-regex CALL check with single negative-lookahead
CYPHER_CALL_DISALLOWED_RE = /\bCALL\s+(?!db\.|apoc\.meta\.)/i
This correctly blocks queries containing ANY disallowed CALL target,
even when bundled alongside an allowed CALL db.* or CALL apoc.meta.*.
- Remove dead CALL\s*\{ alternative from CYPHER_WRITE_RE — the trailing
\b never matched because { is a non-word character.
- Both copies updated identically.
