-Accessibility requirements and compliance for the Burble voice-first communications platform.
-These requirements ensure Burble is usable by everyone, regardless of ability.
+Adaptive-maintenance contract for Echidna. When an upstream dep,
+toolchain, prover binary, schema, or external API shifts, this file
+declares the migration sequence. Each adjustment is an error code, a
+probe to detect drift, and the deterministic-fix-or-defer recipe.

+- description: rust-toolchain.toml pin behind current stable
+- probe: rustc --version | grep -q $(cat rust-toolchain.toml 2>/dev/null | grep channel | cut -d'"' -f2)
+- severity: low
+- adjust: bump rust-toolchain.toml to current stable; run `cargo update --workspace` to refresh transitives
+- defer-if: any pinned-feature crate breaks on bump
+
+### A002-julia-channel-drift
+- description: juliaup default channel mismatches Project.toml `julia` compat
+- probe: julia --version | grep -q "$(grep -E '^julia = ' src/julia/Project.toml | cut -d'"' -f2 | head -1)"
+- severity: low
+- adjust: juliaup default release ; juliaup update
+- defer-if: a key dep (Flux, CUDA, GNN) doesn't yet support new Julia
+
+### A003-chapel-version-bump
+- description: chapel-ci.yml pin behind upstream
+- probe: grep -E '^CHAPEL_VERSION:' .github/workflows/chapel-ci.yml | grep -q '2.8.0'
+- severity: medium
+- adjust: bump CHAPEL_VERSION env in chapel-ci.yml ; verify .deb URL + SHA via curl
+- defer-if: existing chapel source uses removed syntax (out/label keywords, char-quote rules)
+
+### A004-idris2-version-drift
+- description: idris2 binary doesn't match src/abi/echidnaabi.ipkg pin
+- probe: idris2 --version | grep -q "0.8.0"
+- severity: medium
+- adjust: install matching idris2 via guix or upstream binary
+- defer-if: 0.8.0 reserved-keyword rules break src/abi/ (see [[reference_idris2_0_8_0_reserved_keywords]])
+
+### A005-zig-version-drift
+- description: zig binary doesn't match ffi/zig pin
+- probe: zig version | grep -q "0.15"
+- severity: low
+- adjust: install matching zig version
+- defer-if: 0.15 breaking changes hit ffi/zig (see [[reference_zig_015_breaking_changes]])
+
+## Dep-Adjust
+
+### A010-cargo-deps-major-bump-available
+- description: a tracked Cargo dep has a major bump available
+- probe: cargo outdated --workspace --depth 1 2>/dev/null | grep -E '^\w+\s+\S+\s+\S+\s+\d' | head -5
+- severity: low
+- adjust: review changelog; bump via `cargo update -p <crate> --precise <new>`; run full test suite
+- defer-if: major bump introduces API break with no migration path (nom 7→8, rand 0.9→0.10 examples)
+
+### A011-julia-pkg-major-bump-available
+- description: a tracked Julia pkg has a compat-bound bump available
+- probe: julia --project=src/julia -e 'using Pkg; Pkg.status(outdated=true)' 2>&1 | grep -q '⌃'
+- severity: low
+- adjust: review upstream NEWS; bump `[compat]` in Project.toml; Pkg.resolve()
+- defer-if: GNN-stack (Flux/CUDA/GraphNeuralNetworks) interlock requires waiting on co-bump

+### A012-dependabot-pr-backlog
+- description: open dependabot PRs accumulating
+- probe: gh pr list --repo hyperpolymath/echidna --author 'app/dependabot' --state open --limit 50 --json number | jq 'length' | grep -q '^0$'
+- severity: low
+- adjust: triage with `just blocked-pr-triage` style sweep; auto-merge low-risk patches
+- defer-if: dependabot phantom-version (e.g. rand 0.10 not on crates.io)
+
+## Schema-Adjust
+
+### A020-capnp-schema-out-of-sync
+- description: crates/echidna-wire/schemas/*.capnp changed but bindings stale
+- probe: git diff --quiet HEAD~10 crates/echidna-wire/schemas/ && git diff --quiet HEAD~10 crates/echidna-wire/src/
+- severity: high
+- adjust: just capnp-gen ; verify Rust/Julia/Idris2/Zig/AffineScript bindings all regenerated
+- defer-if: schema bump requires owner approval (Cap'n Proto IPC is owner-gated per #194)
+
+### A021-graphql-sdl-no-export
+- description: src/interfaces/graphql/schema.rs changed but no SDL file tracked
+- probe: test -f src/interfaces/graphql/schema.graphql
+- severity: medium
+- adjust: cargo test --package echidna-graphql export_schema (writes schema.graphql) ; commit it
+- defer-if: schema considered internal-only
+
+### A022-openapi-spec-drift
+- description: REST handlers changed but OpenAPI spec stale
+- probe: test -f src/interfaces/rest/openapi.json && cargo run -- export-openapi 2>/dev/null | diff -q - src/interfaces/rest/openapi.json
+- severity: medium
+- adjust: regenerate via aide / utoipa ; commit ; CI diff-gate
+- defer-if: aide/utoipa not yet adopted; file follow-up to wire
+
+### A023-verisim-er-schema-drift
+- description: crates/echidna-wire/schemas/verisim_er.capnp diverged from docs/architecture/VERISIM-ER-SCHEMA.md crosswalk table
+- probe: diff <(grep -E '^\| .+ \| .+ \|' docs/architecture/VERISIM-ER-SCHEMA.md) <(parse schema → rows)
+- severity: high
+- adjust: update whichever lags; both must move together
+- defer-if: VerisimDB upstream schema is itself in flux (federation pending)
+
+## Prover-Adjust
+
+### A030-new-prover-added-upstream
+- description: an upstream prover repo bumped to a new release
+- probe: scripts/provision_corpora.sh --status | grep -E 'ahead' | head -1
+- severity: low
+- adjust: pin new tag in scripts/provision_corpora.sh ; just provision-corpora ; just corpus-ingest-saturation <name> ; retrain
+- defer-if: upstream release breaks the extractor (file in src/rust/corpus/<name>.rs)
+
+### A031-prover-kind-enum-expansion
+- description: a new prover backend is wanted (ProverKind::all_core gap)
+- probe: manual — owner identifies
+- severity: medium
+- adjust: add variant to ProverKind enum; implement ProverBackend trait; wire ProverFactory::create; tier-assign in docs/PROVER_COUNT.md
+- defer-if: prover lacks open-source binary distribution
+
+## Workflow-Adjust
+
+### A040-standards-reusable-sha-stale
+- description: a standards-reusable workflow caller is behind current main
+- probe: grep -rE 'uses: hyperpolymath/standards/.+@[0-9a-f]{40}' .github/workflows/ | while read l; do sha=$(echo "$l" | grep -oE '[0-9a-f]{40}'); current=$(gh api repos/hyperpolymath/standards/commits/main --jq .sha); [ "$sha" = "$current" ] || echo STALE; done | head -1
+- severity: low
+- adjust: bump SHA pin; verify the SHA exists via `gh api repos/hyperpolymath/standards/commits/<sha>`
+- defer-if: a recent reusable change introduces breaking input shape
+
+### A041-action-sha-pin-fake
+- description: a 3rd-party action SHA pin is fake (does not exist upstream)
+- probe: scripts/verify-action-shas.sh 2>&1 | grep -q 'FAKE'
+- severity: critical
+- adjust: replace with current real SHA via `gh api repos/<org>/<action>/commits/<branch>`
+- defer-if: never — fake SHA is a supply-chain hazard
+
+### A042-codeql-cron-drift
+- description: codeql cron drifted from standards canonical schedule (monthly per cut 3)
+- probe: grep -A 2 '^on:' .github/workflows/codeql.yml | grep -q 'cron.*0 0 1 \*'
+- severity: low
+- adjust: bump to '0 0 1 * *' monthly; or drop file entirely and let standards reusable provide
+- defer-if: project-specific gate requires more frequent scan
+
+@adjust-philosophy:
+- always check before adjust (every recipe has both)
+- never adjust without an explicit defer-if escape hatch
+- adjustments cascade: bump rust → cargo update → check tests → check ABI → check container
+- prefer the narrowest change that resolves the drift

+Breakage and rollback contract for Echidna. When a build, test, prover
+backend, ABI proof, container, or training pipeline goes wrong, this

+a probe to detect it, and a `recovery:` recipe pointing at the
+self-heal action.
+
+Error-code namespace: B###
+Recovery sequence is "narrowest-first": prefer reverting a single

+### D001-stale-local-branches
+- description: local branches whose remote-tracking is gone
+- probe: git for-each-ref refs/heads --format '%(refname:short) %(upstream:track)' | grep -q '\[gone\]'
+- severity: low
+- dust: git fetch --prune ; for b in $(git for-each-ref refs/heads --format='%(refname:short) %(upstream:track)' | awk '/gone/ {print $1}'); do gh pr list --repo hyperpolymath/echidna --head "$b" --state merged --json number --jq '.[0].number' | grep -q '^[0-9]' && git branch -D "$b"; done
+- reversible: yes (re-fetch from origin if needed)

+### D002-stale-remote-branches
+- description: remote branches whose PR was squash-merged (git's mergedness detector misses)
+- probe: gh pr list --repo hyperpolymath/echidna --state all --limit 50 --json number,headRefName,state,mergedAt | jq '[.[] | select(.state=="MERGED" and (.mergedAt != null))] | length' | grep -qE '^[1-9]'
+- severity: low
+- dust: per merged PR, `gh api -X DELETE repos/hyperpolymath/echidna/git/refs/heads/<branch>` if still present
+- reversible: PR is the durable record; remote branch can be re-pushed
+
+## Worktree-Dust
+
+### D010-dangling-git-worktrees
+- description: registered worktrees pointing at nonexistent paths
+- probe: ! git worktree list 2>&1 | grep -q '\[prunable\]'
+- severity: low

+- reversible: per-worktree only (no commits at risk if worktree is clean)
+- exclude: /tmp/echidna-saturation (other Claude's territory), /tmp/echidna-training-* (active artefacts)
+
+## Cache-Dust
+
+### D020-cargo-target-bloat
+- description: target/ directory exceeds 5GB
+- probe: test -d target && du -sh target | awk '{print $1}' | grep -qE '^[1-9][0-9]+G$'

+- description: dangling podman images (built then orphaned by re-tag)
+- probe: podman images --filter dangling=true --format '{{.ID}}' | wc -l | grep -qE '^[1-9]'

+- severity: low
+- dust: rm src/chapel/lib*.a src/chapel/*.so src/chapel/*.dylib 2>/dev/null || true
+- reversible: yes (just chapel-build regenerates)
+
+## Process-Dust
+
+### D030-orphan-pid-files
+- description: /tmp/*.pid files pointing at no-longer-running PIDs
+- probe: ls /tmp/echidna-*.pid 2>/dev/null | while read f; do kill -0 $(cat "$f") 2>/dev/null || echo "$f"; done | head -1
+- severity: low
+- dust: for f in /tmp/echidna-*.pid; do kill -0 $(cat "$f") 2>/dev/null || rm -f "$f" "${f%.pid}.status"; done
+- reversible: harmless (re-created by next launcher)
+
+### D031-stale-status-files
+- description: /tmp/*.status files marked RUNNING but process dead
+- probe: ls /tmp/echidna-*.status 2>/dev/null | while read f; do pid=$(cat "${f%.status}.pid" 2>/dev/null); grep -q RUNNING "$f" && [ -n "$pid" ] && ! kill -0 "$pid" 2>/dev/null && echo "$f"; done | head -1
+- severity: low
+- dust: per-file: update status to ORPHANED or remove if no longer of interest
+- reversible: harmless
+
+## Artefact-Dust
+
+### D040-prior-run-models
+- description: models/neural/ from prior training runs that aren't the current canonical
+- probe: ls models/neural/ 2>/dev/null | grep -E 'checkpoint_epoch_[0-9]+' | wc -l | grep -qE '^[4-9]|^[0-9]{2,}'
+- severity: low
+- dust: keep best_model + final_model + gnn_ranker; archive epoch checkpoints under models/neural/archive/<run-id>/
+- reversible: yes (data preserved under archive/)
+
+### D041-corpus-snapshot-overlap
+- description: data/corpus/*.json overlapping with newer saturation outputs
+- probe: ls data/corpus/*.json 2>/dev/null | wc -l | grep -qE '^[1-9][0-9]+'
+- severity: low

+- description: training_data/*.jsonl pre-saturation files no longer canonical
+- probe: ls training_data/proof_states_*.jsonl 2>/dev/null | wc -l | grep -qE '^[1-9]'
+- severity: low
+- dust: archive ; do NOT delete (load-bearing for JSONL-fallback training path until full saturation pipeline is the only entry point)
+- reversible: yes
+
+## Source-Dust
+
+### D050-todo-with-no-issue
+- description: TODO/FIXME comments without a tracking issue reference
+- probe: grep -rnE 'TODO|FIXME|XXX' src/ 2>/dev/null | grep -vE '#[0-9]+' | head -1

+- dust: for each: either open a tracking issue + add `// TODO(#N):` prefix, or close out
+- reversible: yes (comment-only)
+
+### D051-unused-imports
+- description: Rust unused imports
+- probe: cargo clippy --workspace 2>&1 | grep -q 'unused import'
+- severity: low
+- dust: cargo fix --allow-dirty --allow-staged
+- reversible: yes (atomic)
+
+### D052-dead-code-warnings
+- description: dead_code warnings
+- probe: cargo build --workspace 2>&1 | grep -q 'warning: .* is never used'
+- severity: low
+- dust: review each — sometimes legitimate forward-prep; otherwise remove
+- reversible: yes (git history)
+
+@dust-philosophy:
+- "leave no trace": every run should be idempotent
+- "narrow blast radius": never combine destructive ops; one dust action per recipe
+- "reversibility first": every dust action should be undoable from git or by re-running a non-dust recipe
+- "exclusion list is sacred": active worktrees + production artefacts NEVER swept (see exclusions in D011)
