**Notes**:

* Added repo path anchors, ASCII text normalization, safe segment filtering, sensitive segment redaction, and bounded label helpers.
* `normalizeLegionIssuePathSegments` strips protocol and drive prefixes, anchors known repo paths, and falls back to `Uncharted` for empty inputs.
* `sanitizeLegionSectorLabel` builds compact slash-separated labels from sanitized path segments only.

**Files Changed**:

* `.spec_system/specs/phase23-session01-pure-camp-reconciliation/tasks.md` - marked T005 complete.

**Verification**:

* Command/check: inspected `normalizeLegionIssuePathSegments` and `sanitizeLegionSectorLabel` in `apps/web/src/lib/legionCamps.ts`
  * Result: PASS - helpers strip absolute prefixes, use known repo anchors, remove unsafe segments, and bound label length.
  * Evidence: Code only stores sanitized ASCII segments and fallback labels, not raw path roots.
* Command/check: `bash -lc 'source "$HOME/.nvm/nvm.sh" && nvm use 26.2.0 >/dev/null && npm --workspace apps/web run typecheck'`
  * Result: PASS - web TypeScript project compiled after adding helpers.
  * Evidence: `tsc -b --noEmit` exited 0.
* UI product-surface check: N/A - pure helper code only.

* `.spec_system/specs/phase23-session01-pure-camp-reconciliation/tasks.md` - marked T006 complete.

**Verification**:

* Command/check: inspected `stableLegionCampHash`, `legionSectorIdForKey`, `legionCampIdForSectorKey`, and `legionCellForSectorKey` in `apps/web/src/lib/legionCamps.ts`
  * Result: PASS - ids are deterministic and cell placement preserves a previous cell for unchanged sector keys.
  * Evidence: The cell helper reuses `previousSectors[sectorId].cell` only when `dirKey` matches and the cell is valid.
* Command/check: `bash -lc 'source "$HOME/.nvm/nvm.sh" && nvm use 26.2.0 >/dev/null && npm --workspace apps/web run typecheck'`
  * Result: PASS - web TypeScript project compiled after adding helpers.
  * Evidence: `tsc -b --noEmit` exited 0.
* UI product-surface check: N/A - pure helper code only.
* UI craft check: N/A - no UI surface changed.

**BQC Fixes**:

* Contract alignment: camp ids and sector ids are both derived from the same safe sector key, matching the Phase 23 contract that camp ids are sector ids.
* State freshness on re-entry: previous cell reuse is conditional on matching sector identity, preventing stale cell carryover for changed sectors.

***

### 2026-07-05 16:41 - Checkpoint After T006

* Tests/checks: web typecheck passed.

* `.spec_system/specs/phase23-session01-pure-camp-reconciliation/tasks.md` - marked T007 complete.

**Verification**:

* Command/check: inspected `apps/web/tests/legionCamps.test.ts`
  * Result: PASS - factories create contract-shaped codebase issue, camp, and sector fixtures.
  * Evidence: Fixture smoke test asserts stable defaults for `id`, `severity`, `filePath`, `issueIds`, `tier`, `dirKey`, and `cell`.
* Command/check: `bash -lc 'source "$HOME/.nvm/nvm.sh" && nvm use 26.2.0 >/dev/null && npm test -- apps/web/tests/legionCamps.test.ts'`

* `.spec_system/specs/phase23-session01-pure-camp-reconciliation/tasks.md` - marked T008 complete.

**Verification**:

* Command/check: inspected `issueSeverityWeight` and `legionCampTierForHp` in `apps/web/src/lib/legionCamps.ts`
  * Result: PASS - `error`, `warning`, and `info` map through the exhaustive constant map and tier gates resolve `camp`, `fort`, and `citadel`.
  * Evidence: Unknown severity values are routed through a `never` assertion at compile time.
* Command/check: `bash -lc 'source "$HOME/.nvm/nvm.sh" && nvm use 26.2.0 >/dev/null && npm --workspace apps/web run typecheck'`
  * Result: PASS - web TypeScript project compiled after adding helpers.
  * Evidence: `tsc -b --noEmit` exited 0.

* Added small-repo deeper splitting when primary grouping is too coarse.
* Added sector budget enforcement with deterministic high-pressure retention and `Borderlands` overflow grouping.
* Added sector record creation with stable ids, previous-cell reuse, `fogPct: 0`, and aggregate newest issue timestamps.

**Files Changed**:

* `apps/web/src/lib/legionCamps.ts` - added sector candidate, grouping, budgeting, and sector record helpers.
* `.spec_system/specs/phase23-session01-pure-camp-reconciliation/implementation-notes.md` - recorded T009 evidence and progress.
* `.spec_system/specs/phase23-session01-pure-camp-reconciliation/tasks.md` - marked T009 complete.

**Verification**:

* Command/check: inspected `buildLegionCampSectorGroups` and its candidate/group selection helpers in `apps/web/src/lib/legionCamps.ts`
  * Result: PASS - sector grouping derives safe keys before ids, deep-splits under the readable-sector floor, caps sector count, and sorts output deterministically.
  * Evidence: Overflow issues are grouped into `LEGION_CAMP_BORDERLANDS_KEY` before sector ids and cells are created.
* Command/check: `bash -lc 'source "$HOME/.nvm/nvm.sh" && nvm use 26.2.0 >/dev/null && npm --workspace apps/web run typecheck'`
  * Result: PASS - web TypeScript project compiled after sector grouping helpers.
  * Evidence: `tsc -b --noEmit` exited 0.
* UI product-surface check: N/A - pure helper code only.
* UI craft check: N/A - no UI surface changed.

**BQC Fixes**:

* Trust boundary enforcement: sector ids and records are derived only after path labels are sanitized and budgeted.

***

### 2026-07-05 16:44 - After T009

* Tests/checks: web typecheck passed.
* Scope check: pure sector reconciliation only; no UI, storage, reducer, or protocol change.

* `.spec_system/specs/phase23-session01-pure-camp-reconciliation/tasks.md` - marked T010 complete.

**Verification**:

* Command/check: inspected `uniqueLegionIssuesById` and `buildLegionCampIssueGroups` in `apps/web/src/lib/legionCamps.ts`
  * Result: PASS - camp groups use sorted unique issue ids and HP sums over the deduped current issue list.
  * Evidence: `issueIds` are mapped from sorted unique issues and HP is reduced through `issueSeverityWeight`.
* Command/check: `bash -lc 'source "$HOME/.nvm/nvm.sh" && nvm use 26.2.0 >/dev/null && npm --workspace apps/web run typecheck'`
  * Result: PASS - web TypeScript project compiled after camp grouping helpers.
  * Evidence: `tsc -b --noEmit` exited 0.
* UI product-surface check: N/A - pure helper code only.
* UI craft check: N/A - no UI surface changed.

**BQC Fixes**:

* Contract alignment: camp grouping preserves the projection contract by emitting only issue ids, aggregate HP, and a `CampTier`.
* Failure path completeness: duplicate issue ids are handled deterministically instead of inflating HP.

***

### 2026-07-05 16:45 - After T010

* Tests/checks: web typecheck passed.
* Scope check: pure grouping logic only; no reducer, UI, protocol, persistence, rewards, or storage changes.

### Task T013 - Implement reconcileLegionCamps outputs

**Started**: 2026-07-05 16:47 **Completed**: 2026-07-05 16:48 **Duration**: 1 minute

**Notes**:

* Added public `reconcileLegionCamps`.
* Clean snapshots return empty camp and sector records with no stale ids.
* Current snapshots dedupe issue ids, derive current sector groups, build current camps, and classify new versus changed surviving camp ids.
* Removed camps are naturally omitted because output is rebuilt from the current scanner snapshot.

**Files Changed**:

* `apps/web/src/lib/legionCamps.ts` - added public reconciliation function, sorted record helper, camp comparison, and timestamp normalization.

  * Result: PASS - clean snapshots remove stale state, current snapshots build only aggregate camps and sectors, and new/changed ids are deterministic.
  * Evidence: Output records include no raw issue messages, prompts, file contents, terminal output, provider payloads, or absolute path fields.
* Command/check: `bash -lc 'source "$HOME/.nvm/nvm.sh" && nvm use 26.2.0 >/dev/null && npm --workspace apps/web run typecheck'`
  * Result: PASS - web TypeScript project compiled after public reconciliation implementation.
  * Evidence: `tsc -b --noEmit` exited 0.
* UI product-surface check: N/A - pure helper code only.
* UI craft check: N/A - no UI surface changed.

**BQC Fixes**:

* State freshness on re-entry: reconciliation rebuilds camps and sectors from the current snapshot and drops absent state.
* Error information boundaries: public output includes aggregate ids, safe labels, HP, tier, counters, cells, and timestamps only.

### 2026-07-05 16:48 - After T013

* Tests/checks: web typecheck passed.
* Scope check: no reducer or persistence wiring; function remains pure and aggregate-only.
* Next task: T014 implement base `rankVisibleLegionCamps`.

### Task T014 - Implement base rankVisibleLegionCamps

**Started**: 2026-07-05 16:48 **Completed**: 2026-07-05 16:48 **Duration**: 1 minute

**Notes**:

* Added public `rankVisibleLegionCamps`.
* Ranking exposes cloned aggregate camp data, safe sector metadata, sorted issue ids, newest issue timestamp, and entrenched/muted flags.
* Stable ordering keeps unmuted camps first, then tier, HP, newest timestamp, sector label, and camp id.

**Files Changed**:

* `apps/web/src/lib/legionCamps.ts` - added base ranking helper and ranking sort helpers.
* `.spec_system/specs/phase23-session01-pure-camp-reconciliation/implementation-notes.md` - recorded T014 evidence and progress.
* `.spec_system/specs/phase23-session01-pure-camp-reconciliation/tasks.md` - marked T014 complete.

**Verification**:

* Command/check: inspected `rankVisibleLegionCamps` and `compareRankedLegionCamps` in `apps/web/src/lib/legionCamps.ts`
  * Result: PASS - helper exposes entrenched/muted metadata and stable order without mutating source camps.
  * Evidence: Returned `camp.issueIds` and sector objects are cloned and no raw issue text/path fields are returned.
* Command/check: `bash -lc 'source "$HOME/.nvm/nvm.sh" && nvm use 26.2.0 >/dev/null && npm --workspace apps/web run typecheck'`
  * Result: PASS - web TypeScript project compiled after base ranking helper.
  * Evidence: `tsc -b --noEmit` exited 0.
* UI product-surface check: N/A - pure selector helper only.
* UI craft check: N/A - no UI surface changed.

**BQC Fixes**:

* Error information boundaries: ranking output includes issue ids and aggregate metadata only, not raw scanner issue messages, prompts, or file paths.
* Contract alignment: ranking remains a selector over existing projection-shaped records.

***

### 2026-07-05 16:48 - Checkpoint After T014

* Tests/checks: web typecheck passed.
* Scope check: implementation work remains inside the pure module and focused tests; Session 02 ranking limits and UI are not implemented here.
* Next task: T015 add severity, tier, aggregate HP, and sorted issue id tests.

### Task T015 - Add severity, tier, HP, and issue id tests

**Started**: 2026-07-05 16:49 **Completed**: 2026-07-05 16:50 **Duration**: 1 minute

**Notes**:

* Added tests for scanner severity weights and camp tier thresholds.
* Added reconciliation coverage for aggregate HP, sorted unique issue ids, new camp ids, and unchanged changed-camp output for new camps.

**Files Changed**:

* `apps/web/tests/legionCamps.test.ts` - added severity, tier, aggregate HP, and sorted issue id tests.
* `.spec_system/specs/phase23-session01-pure-camp-reconciliation/implementation-notes.md` - recorded T015 evidence and progress.
* `.spec_system/specs/phase23-session01-pure-camp-reconciliation/tasks.md` - marked T015 complete.

**Verification**:

* Command/check: `bash -lc 'source "$HOME/.nvm/nvm.sh" && nvm use 26.2.0 >/dev/null && npm test -- apps/web/tests/legionCamps.test.ts'`
  * Result: PASS - focused Legion camp tests passed.
  * Evidence: Vitest exited 0 with severity/tier/HP tests included.
* Command/check: targeted inspection of `apps/web/tests/legionCamps.test.ts`
  * Result: PASS - tests exercise public helpers and `reconcileLegionCamps` output instead of internal implementation details.
  * Evidence: Assertions cover `hp`, `maxHp`, `tier`, sorted `issueIds`, `newCampIds`, and `changedCampIds`.
* UI product-surface check: N/A - pure helper tests only.
* UI craft check: N/A - no UI surface changed.

**BQC Fixes**:

* Contract alignment: tests prove HP and tier outputs match the declared Phase 23 constants.

### 2026-07-05 16:50 - After T015

* Tests/checks: focused Legion camp tests passed.
* Scope check: test coverage remains pure and aggregate-only.
* Next task: T016 add sector coalescing and stability tests.

### Task T016 - Add sector coalescing and stability tests

**Started**: 2026-07-05 16:50 **Completed**: 2026-07-05 16:51 **Duration**: 1 minute

**Notes**:

* Added small-repo deeper split coverage.
* Added large-repo sector budget and `Borderlands` overflow coverage.
* Added absolute/sensitive path label sanitation coverage.
* Added stable cell preservation and sorted record key coverage.

**Files Changed**:

* `apps/web/tests/legionCamps.test.ts` - added sector coalescing, safe label, stable ordering, and stable cell tests.
* `.spec_system/specs/phase23-session01-pure-camp-reconciliation/implementation-notes.md` - recorded T016 evidence and progress.
* `.spec_system/specs/phase23-session01-pure-camp-reconciliation/tasks.md` - marked T016 complete.

**Verification**:

* Command/check: `bash -lc 'source "$HOME/.nvm/nvm.sh" && nvm use 26.2.0 >/dev/null && npm test -- apps/web/tests/legionCamps.test.ts'`
  * Result: PASS - focused Legion camp tests passed with sector coverage.
  * Evidence: Vitest exited 0 with small-repo, large-repo, `Borderlands`, safe label, stable key, and stable cell assertions included.
* Command/check: targeted inspection of `apps/web/tests/legionCamps.test.ts`
  * Result: PASS - tests assert public reconciliation output instead of private sector helpers.
  * Evidence: Assertions inspect `sectors`, `camps`, cells, keys, and serialized aggregate output.
* UI product-surface check: N/A - pure helper tests only.
* UI craft check: N/A - no UI surface changed.

**BQC Fixes**:

* Trust boundary enforcement: tests prove absolute root and sensitive path segments stay out of aggregate output.

***

### 2026-07-05 16:51 - After T016

* Tests/checks: focused Legion camp tests passed.
* Scope check: no UI, reducer, protocol, or persistence behavior added by tests.
* Next task: T017 add entrenchment, preservation, clean snapshot, and aggregate-only privacy tests.

### Task T017 - Add entrenchment, preservation, clean snapshot, and privacy tests

**Started**: 2026-07-05 16:51 **Completed**: 2026-07-05 16:52 **Duration**: 1 minute

**Notes**:

* Added repeated-snapshot entrenchment increment coverage.
* Added HP and membership change reset coverage.
* Added previous `maxHp` and `scarredPct` preservation coverage.
* Added clean snapshot stale-state removal coverage.
* Added aggregate-only privacy coverage and base entrenched ranking metadata coverage.

**Files Changed**:

* `apps/web/tests/legionCamps.test.ts` - added entrenchment, preservation, clean snapshot, privacy, and ranking metadata tests.
* `.spec_system/specs/phase23-session01-pure-camp-reconciliation/implementation-notes.md` - recorded T017 evidence and progress.
* `.spec_system/specs/phase23-session01-pure-camp-reconciliation/tasks.md` - marked T017 complete.

**Verification**:

* Command/check: `bash -lc 'source "$HOME/.nvm/nvm.sh" && nvm use 26.2.0 >/dev/null && npm test -- apps/web/tests/legionCamps.test.ts'`
  * Result: PASS - focused Legion camp tests passed with entrenchment and privacy coverage.
  * Evidence: Vitest exited 0 with repeated-scan, reset, clean snapshot, aggregate-only, and ranking metadata assertions included.
* Command/check: targeted inspection of `apps/web/tests/legionCamps.test.ts`
  * Result: PASS - privacy assertions check serialized public output, not implementation internals.
  * Evidence: Raw messages, prompts, terminal output, provider payload, file contents, absolute path, and sensitive path segment strings are rejected.
* UI product-surface check: N/A - pure helper tests only.
* UI craft check: N/A - no UI surface changed.

**BQC Fixes**:

* State freshness on re-entry: tests prove clean snapshots remove stale state and changed camp content resets entrenchment.
* Error information boundaries: tests prove raw scanner detail does not enter public aggregate output.
